  The present invention relates to an imaging device and an imaging system including the same.

  2. Description of the Related Art Conventionally, there is known an imaging device such as a security camera or a drive recorder, which can change the shooting direction of a camera attached to an arbitrary attachment position by changing the orientation of the lens of the camera with respect to the attachment member. For example, in a drive recorder, a drive recorder main body having a cylindrical portion (hereinafter referred to as a "dra recorder main body") is attached to the windshield of a vehicle with the cylindrical portion horizontal, and vertically in the horizontal direction as a rotation axis.

JP, 2010-105530, A

  Here, the drive recorder described above is generally attached to the windshield of the vehicle and used for photographing in front of the vehicle, but may not be used as a rear camera for imaging the rear of the vehicle by attaching to the rear glass of the vehicle Thought.

  However, for example, in the case of a one-box type vehicle in which the rear glass is erected almost vertically, after attaching the camera to the rear glass with the mounting member, facing the camera against the rear glass, one of the mounting members mounted on the rear glass The unit may be reflected in the image taken by the camera. In particular, when a wide-angle lens is used, the mounting member tends to be reflected, which may affect the reproduced image. Moreover, when attaching a camera to a rear glass, it discovered that it was desirable to make it as small as possible and to make it inconspicuous, etc., and various problems exist.

  Then, an object of this invention is to provide the small imaging device which can be attached to a desired attachment location, for example in the state which prevented the reflection of the attachment member, and an imaging system provided with the same.

(1) An imaging apparatus comprising: a camera; and a mounting member for mounting the camera at a desired mounting location, wherein the mounting member includes support means for supporting the camera, and a photographing direction of the camera. An imaging apparatus comprising an attachment plate configured to be attachable to the desired attachment point on one side orthogonal to the attachment plate and extending in a direction away from the lens of the camera.

  According to this, when the camera is attached to the desired attachment point so that the desired attachment point and the lens substantially face each other, the attachment plate is attached to the image taken by the camera while earning the attachment area of the attachment plate to the desired attachment point The lens and the mounting plate can be brought close to each other so that the plate is not reflected. That is, the camera can be downsized in a state in which the reflection of the attachment member is prevented.

  For example, if the mounting plate is made smaller in order to eliminate reflections, the mounting plate may become easy to peel off or become unstable if it is stuck to a desired mounting location with double-sided tape etc. By extending them in the direction away from each other, the mounting area of the mounting plate can be increased while the influence on the reflection is suppressed. That is, it is possible to make the mounting plate less likely to be detached from the desired mounting location and to be stable relative to the desired mounting location.

  The desired attachment location may be the desired location at the place where the camera can be attached, for example, the desired location on the rear glass of the vehicle or the desired location on the window glass of the building.

  The support means may be configured to support the camera so as to change the direction of the lens of the camera, and may be configured to rotatably support the camera. In particular, the camera may be supported so as to be able to rotate 360 degrees. For example, if the camera is substantially cylindrical, the support means may be ring-shaped.

  In the case where the support means rotatably supports the camera, the camera may be supported so as to rotate smoothly, and more preferably, the camera may be supported so as to rotate stepwise. For example, the camera may be supported so as to rotate by 5 degrees with respect to the rotation support member.

  Further, in the case where the support means rotatably supports the camera, it is preferable to provide a fixing means for fixing the support means at an arbitrary rotational position. The fixing means may be configured to rotate, for example, when a predetermined rotational torque or more acts, and to hold the rotational position when a rotational torque less than a predetermined torque is applied. For example, it is preferable that the rotational torque by a user rotates the camera be a rotational torque that is greater than or equal to a predetermined value. The rotational torque that is less than a predetermined value be a rotational torque that acts due to vibration of a mounting location (for example, vehicle) . Further, it is preferable that the camera and the fixing means sandwich and fix the supporting means. In this case, the fixing means may be a fixing member which is screwed into the camera to hold the supporting means.

  The mounting plate may be configured to extend from the support means in a direction away from the lens, and more preferably extend from an end of the support means. For example, the mounting plate may be connected to the support means directly or indirectly.

  The shape of the mounting plate is not particularly limited, but may be rectangular, and at least the length in the direction away from the lens may be longer than the length in the direction substantially orthogonal to the direction away from the lens. For example, it may be a substantially rectangular shape in which the direction away from the lens is the longitudinal direction.

  The direction away from the lens may be a radial direction with respect to the lens, and in this case, it may be substantially fan-shaped. The direction away from the lens may be extended in one direction in the radial direction, and in this case, it may be substantially rectangular. For example, in the case where the camera has a substantially cylindrical shape and the lens is disposed on the outer peripheral surface, the direction along the central axis of the camera may be taken.

  The length of the mounting plate in the direction away from the lens (for example, the length in the longitudinal direction) is, for example, adhesion of a position where the camera does not come off unnecessarily from the mounting location It is sufficient to have a bonding area where double-sided tape can exert its force. In this case, the mounting surface of the mounting plate may be substantially flat. By making the mounting surface substantially flat, for example, it becomes easy to attach the mounting plate with a double-sided adhesive tape to any mounting location. For example, the length in the direction away from the lens may be configured so as not to protrude as much as possible from the end of the camera.

  The camera may be configured to have a substantially cylindrical portion in a part, and the whole may be substantially cylindrical. By making the whole camera into a substantially cylindrical shape, it is possible to reduce the change in the shape of the camera when the camera is rotated, for example, use it without discomfort even if it is rotated after being attached to any mounting location. Can. Further, by making the entire camera into a substantially cylindrical shape, for example, it becomes easy to pick the camera, and it is possible to easily rotate the camera when changing the shooting direction. Furthermore, by making the entire camera into a substantially cylindrical shape, it is possible to make the appearance of the camera look pretty.

  The camera may be configured to use a wide-angle lens, for example, a wide-angle lens having a diagonal of 150 to 170 degrees. For example, when attached to the windshield of a car, it is possible to capture a range up to the extent that a pillow appears at a diagonal angle of 160 degrees, and to capture the situation of a vehicle traveling in the right and left lanes when stopping at an intersection . In addition, for example, in a working vehicle such as a forklift, it is possible to capture images including those on the road outside the working vehicle such as a forklift. For this reason, it is possible to confirm from a video recorded a working vehicle such as a forklift stepping on something, dropping a load, or having a step.

(2) The mounting plate has notches at both ends on the lens side in a direction substantially orthogonal to the separating direction when the mounting plate is positioned on the one side of the camera.

  According to this, the lens and the mounting member can be made closer to each other than when the notch is not provided. For example, the mounting plate can be placed in close proximity to the lens. That is, further downsizing of the camera unit is possible. In particular, even in the case of using a wide-angle lens, the lens and the mounting plate can be brought close to each other without the mounting plate being reflected in the image captured by the camera by notching the both ends on the lens side.

  The shape of the notch may be a shape and / or a range based on the range of the image captured by the camera, and in particular, a shape and / or a distortion of the imaging range of the camera caused by the configuration of the optical system. Or it is good to make it a range.

  For example, the shape of the notch may be a rectangular shape, and the notch may be formed more easily and reliably by notching in a rectangular shape.

(3) The attaching member is characterized by having band attaching means capable of attaching a fixing band for fixing the attaching member attached to the desired attachment point to the desired attachment point.

  According to this, the fixing member can be fixed by the fixing band so that the mounting member attached to the desired mounting point does not come off from the desired mounting point. For example, when the attachment member is attached to the outside of the vehicle with a double-sided tape, etc., the attachment member can be prevented from dropping off from the desired attachment location even when the adhesive force of the double-sided tape is reduced.

  For example, the fixing band may be wound around a frame of a work vehicle such as a forklift and the like so as to be fixed, or may have a one-way mechanism which can be tightened only in one direction and does not loosen once tightened. The shape of the fixing band may be a band. For example, a binding band may be used as the fixing band.

  The band attachment means may be provided on the side opposite to the attachment face of the attachment plate, or may be provided on the support means.

  Further, it may be provided at the connecting portion between the mounting plate and the support means. If the connection between the mounting plate and the support means is provided with band attachment means, it may be provided so that the strength of the connection does not decrease. For example, in the case where an insertion hole through which the fixing band can be inserted is provided in the connection part, the connection part may be enlarged so that the strength of the connection part is increased. The size of the

  In addition, the band attachment means may be configured to be able to attach the fixing band so that the fixing band fixes the attachment member while pressing the attachment plate to the desired attachment point, and the desired attachment point and attachment plate The fixing band may be configured to be attachable so that the fixing band fixes the attaching member in a state of being collectively entrapped. For example, when the mounting plate is mounted on the frame of a work vehicle such as a forklift, the band mounting means may be configured such that the mounting plate can be tightened and fixed together with the frame by the fixing band.

  For example, as the band attachment means, it is preferable that the fixing band is a locking part that can be locked. In this case, the mounting plate and the frame are bundled together by the fixing band in a state where the fixing band is locked to the locking part. It is good to make it the structure fixed. The band attachment means is preferably an insertion hole through which the fixing band can be inserted. In this case, with the fixing band inserted, the mounting plate and the frame are collectively fixed by the fixing band. Good.

  For example, in the case where the fixing band is fixed to the mounting plate with the frame of a work vehicle such as a forklift, the insertion hole is formed so as to allow the fixing band to be inserted in a direction that can be wound in a direction substantially orthogonal to the longitudinal direction of the frame. Good. In this way, the mounting plate can be easily fixed to the frame and the fixing band can be shortened.

(4) The mounting plate is connected to the supporting means so as to be symmetrical in a direction orthogonal to the separating direction.

  According to this, when the camera is attached to a desired attachment point so that the desired attachment point and the lens substantially face each other, the lens and the desired attachment point can be brought close to each other. For example, when the camera is attached to the rear glass of the vehicle, it is possible to prevent the camera appearing on the rear glass of the vehicle from being photographed. Also, for example, after being attached to a desired attachment point, the lens can be brought close to the desired attachment point in a state in which the camera is rotated to face the lens to the desired attachment point.

  As a configuration connected to the support means so as to be symmetrical in a direction substantially orthogonal to the separating direction of the mounting plate, for example, the central portion in the direction orthogonal to the separating direction is from the other portion in the orthogonal direction Also, it may be connected to the outer peripheral surface of the support means in a state close to the outer peripheral surface of the support means. For example, in the case where the mounting plate has a substantially rectangular shape, it is preferable that the center in the lateral direction of the mounting plate is connected so as to be closest to the outer peripheral surface of the support means.

(5) The camera has a substantially cylindrical portion, and the support means has a rotational support portion rotatably supporting the substantially cylindrical portion, and the mounting plate is substantially in the axial direction of the substantially cylindrical portion. It is characterized in that it extends in the direction away from the lens in parallel.

  According to this, when the camera is attached to a desired attachment point, the direction of the camera can be easily changed by rotating the camera relative to the rotation support portion. For example, when the lens of the camera is provided at the tip of the substantially cylindrical portion in the axial direction (for example, when the photographing direction of the camera is substantially parallel to the axial direction of the substantially cylindrical portion) The camera can be rotated and adjusted so that the image when projected is the image that is normally viewed. When the lens of the camera is provided on the outer peripheral surface of the substantially cylindrical portion (when the shooting direction of the camera is substantially parallel to the direction substantially orthogonal to the axial direction), the axial direction of the substantially cylindrical portion is taken as the rotation center. The shooting direction of the camera can be easily changed.

  The camera may have a shape having a substantially cylindrical portion in part, and it is more preferable that the whole has a substantially cylindrical shape. By making the whole camera into a substantially cylindrical shape, it is possible to reduce the change in the shape of the camera when the camera is rotated, for example, using it without discomfort even if it is rotated after being attached to a desired mounting location. Can. Further, by making the entire camera into a substantially cylindrical shape, for example, it becomes easy to pick the camera, and it is possible to easily rotate the camera when changing the shooting direction. Furthermore, by making the entire camera into a substantially cylindrical shape, it is possible to make the appearance of the camera look pretty.

  Further, the entire camera may be formed into a substantially cylindrical shape, and a part on the outer peripheral surface may be cut away to provide a flat portion. In this case, a monitor that projects an image may be disposed on the flat portion.

  The lens of the camera may be disposed at an axial tip end of the substantially cylindrical portion, and more preferably disposed on an outer peripheral surface of the substantially cylindrical portion.

  When the lens is disposed on the outer circumferential surface of the camera, the lens may be disposed so as not to protrude at least the outer side than the mounting plate on the outer circumferential surface of the substantially cylindrical portion, so that the image is not broken by the outer circumferential surface It may be disposed on the outer peripheral surface. The camera can be miniaturized by making the lens not protrude from the outer peripheral surface as much as possible. Also, the camera can be cleaned.

  In the camera, the portion where the rotation support portion is disposed may be formed in a concave shape, and when the rotation support portion is attached, the outer peripheral surface of the rotation support portion and the outer peripheral surface of the substantially cylindrical portion are substantially coplanar. It is even better to configure in such a concave shape. By configuring the outer peripheral surface of the rotation support portion and the outer peripheral surface of the substantially cylindrical portion to be located on the same plane, the overall shape of the camera can be clarified.

  Further, for example, when the housing of the camera is formed of two members, the screw portion connecting the two members may be formed in a concave portion in which the rotation support portion is disposed. By forming the concave portion, when the rotation support portion is disposed, the screw portion can be concealed.

  (6) The camera is characterized in that it has a hole, and in the hole, there is provided a connected portion to which the connecting portion of the connection cable can be connected.

  According to this, it is possible to hide the connected part. For example, the connected portion can be prevented from being exposed to the outside.

  The hole portion may be formed, for example, so that the connection portion of the connection cable to which the packing is attached can be inserted while bringing the packing into close contact with the inner wall. By doing this, it is possible to make the inside of the hole in a state in which the connection portion of the connection cable is connected to the connected portion waterproof. Further, for example, when the connector of the connection portion of the connection cable is an HDMI male connector, the connected portion may be an HDMI female connector capable of connecting an HDMI male connector.

  (7) The connected portion provided in the hole is provided with a guiding means capable of guiding the connection portion of the connection cable.

  According to this, even when the connected portion is provided in the hole, the connecting portion of the connection cable and the connected portion can be easily connected. In other words, even when the connected portion in the hole can not be seen, the connection portion of the connection cable and the connected portion can be easily connected. For example, when the connection portion of the connection cable is substantially cylindrical with respect to the substantially cylindrical hole portion, the connection portion can be easily connected to the connection portion simply by rotating the connection portion and searching for the guide portion.

  As a guiding means, for example, a protrusion may be provided at the connection portion of the connection cable, and a groove capable of guiding the protrusion toward the connection portion may be provided on the inner wall of the hole. The groove may be provided, and the inner wall of the hole may be provided with a projection capable of guiding the groove to the connected portion.

  By providing the groove portion in the connection portion of the connection cable, for example, packing such as an O-ring can be easily attached to the connection portion of the connection cable.

  Also, by providing a projection on the inner wall of the hole, for example, when attaching the connection portion of the connection cable to the hole, the connection portion with the connector portion (for example, male connector) of the connection portion of the connection cable is connected When the connection directions of the parts (for example, the female connector) do not match, the tip of the mold part of the connection part can contact the projection of the hole, so the connector part provided at the tip of the connection part becomes unnecessary. It is possible to prevent damage or the like by contacting the connected portion. In this case, the length of the projection may be longer than the length of the connector.

  (8) The hole is formed at the end of the substantially cylindrical portion in the axial direction, and the connected portion is provided such that the connecting portion of the connection cable can be detached in the axial direction. It is characterized by

  According to this, attachment and detachment of the connection portion of the connection cable with respect to the connected portion can be facilitated. For example, when the camera is substantially cylindrical, the cylindrical portion of the camera is pinched with one hand, and the connecting portion of the connection cable is pinched with the other hand. It can be pulled out of the connection.

  Also, for example, when the camera has a substantially cylindrical shape and the mounting plate extends in the axial direction, the mounting plate can be made inconspicuous by connecting the connection portion of the connection cable to the connected portion.

  Furthermore, for example, when the camera has a substantially cylindrical shape and the mounting plate extends in the axial direction, the connection portion of the connection cable can be axially detached from the connected portion, so the connection portion of the connection cable When attaching or removing the mounting plate, the mounting plate can be made difficult to peel off from the mounting location.

  The hole portion may be formed, for example, in such a size that the connection portion of the connection cable in which the packing such as an O-ring is fitted can be inserted, and the size may be such that the packing collapses appropriately. By forming in this way, it is possible to make the connection point between the connected part inside the hole and the connection part of the connection cable waterproof. In this case, it is preferable to provide an attachment portion (for example, an attachment groove) to which a packing such as an O-ring can be attached to the connection portion of the connection cable. By providing the attachment portion, when inserting the connection portion of the connection cable into the hole portion, the packing such as the O-ring can not be easily detached from the connection portion of the connection cable.

  (9) The hole portion is formed at the deepest portion in the axial direction of the substantially cylindrical portion, and the connected portion is characterized in that the connection portion of the connection cable is detachably provided in the axial direction. I assume.

  According to this, since the connected portion is provided at the end of the hole provided in the axial direction, for example, the connection portion (for example, HDMI male connector) of the connection cable can be connected to the connected portion (for example, HDMI female) It can be made difficult to remove from the connector.

  (10) The image pickup device described above, a recording device for recording image data captured by the camera of the image pickup device, and a connection cable for connecting the camera and the recording device are provided.

  According to this, it is possible to miniaturize the camera by separately configuring the camera and the recording device that records the video captured by the camera.

  The connection cable may be configured to be connected in a fixed state to the camera and the recording device (for example, in a state where it can not be pulled out from the camera and the recording device). The configuration in which the connection cable is not pulled out can prevent the connection cable from being pulled out of the camera or the recording device unnecessarily. As a configuration that does not pull out, it may be configured that it can not be pulled out from the beginning, or it may be configured that it can not be pulled out once it is connected. In addition, once connected, removal may be difficult. The configuration that makes extraction difficult may be configuration for the imaging device and the connected portion.

  In addition, it is preferable that the camera and the recording apparatus be configured to be attachable to and detachable from the camera. With this configuration, for example, it is possible to prevent the entire imaging system from being removed or replaced at the time of maintenance, failure, or the like.

  Further, in the connection cable, it is preferable that the shape of the molded portion of the connection cable be different between the camera side and the recording device side in the same state of the electrical wiring. For example, the shape of the mold portion on the camera side may be substantially cylindrical, and the shape of the mold portion on the recording device side may be substantially rectangular. For example, the connection destination of the connection cable may be uniquely determined. By making the shape of the mold portion different, for example, the mold portion on the camera side desired to be waterproofed for installation outdoors has a substantially cylindrical shape and enters the inside of the camera, and the mounting location is waterproofed In the case where the mold portion on the recording device side which does not require waterproofing is formed into a substantially rectangular parallelepiped shape so as not to enter the inside of the recording device, it is possible to prevent erroneous connection. Furthermore, in the case of a substantially cylindrical shape, it is preferable that the connection direction be recognized immediately. For example, a mark indicating the connection direction may be provided.

  (11) The connection cable is detachably configured to the imaging device and the recording device.

  According to this, it is possible to select the connecting cable of the required length and connect the imaging device and the recording device. Therefore, depending on the relationship between the mounting location of the imaging device and the installation position of the recording device, It is possible to prevent the length from being insufficient or being too long. Also, for example, since the camera can be rotated in a state where the connection cable is not connected, the camera can be easily rotated. For example, when rotating the camera in a narrow place or the like, the connection cable does not get in the way.

  For example, in the case of transmitting large-capacity data such as video, it is possible to prevent the video from being obscured by increasing the cable length using a connector. In addition, it is possible to prevent the connection cable from being in the way by being too long.

  Further, each of the imaging device, the recording device, and the connection cable can be individually repaired or replaced at the time of maintenance or at the time of failure.

  The connector portion of the connection portion of the connection cable may be a non-circular connector. For example, the connector portion may have a substantially rectangular parallelepiped shape. The connector portion of the connection portion of the connection cable may use a standardized connector, and in particular, a connector standardized for an application. For example, it is more preferable to use a connector of USB or HDMI cable (hereinafter referred to as "HDMI connector"). By using a standardized HDMI connector, the number of pins can be increased in size and cost. In particular, using pins different from the standardized connector standard, for example, only 5 pins can be obtained in the case of a USB cable connector, but in the case of an HDMI connector, 5 pins or more (for example, 12 pins or more) ) Can be taken. The number of pins may be, for example, eight. In particular, a connector capable of transmitting both power and video may be used. The power may be supplied from the main body side or, conversely, may be supplied from the camera to the main body.

  (12) The camera has a hole, and the hole is provided with a connection terminal to which a connection terminal provided at the tip of the connection portion of the connection cable can be connected. .

  According to this, it is possible to hide the connected terminal. For example, exposure of the connected terminal to the outside can be prevented.

  The hole portion may be formed, for example, so that the connection portion of the connection cable to which the packing is attached can be inserted while bringing the packing into close contact with the inner wall. By doing this, the inside of the hole in a state where the connection terminal of the connection portion of the connection cable is connected to the connection terminal can be made waterproof. Further, for example, when the connection terminal of the connection portion of the connection cable is an HDMI male connector, the connection terminal may be an HDMI female connector capable of connecting an HDMI male connector.

  (13) The hole portion is formed in a substantially cylindrical shape, and the connection portion of the connection cable is formed in a substantially cylindrical shape attachable to the hole portion in a state where a predetermined packing is attached. It features.

  According to this, by forming the hole and the connection portion of the connection cable in a substantially cylindrical shape, it is possible to improve the waterproof performance in the case where the packing is interposed between the hole and the connection portion of the connection cable.

  The predetermined packing may be, for example, an O-ring, and the connection portion may be provided with a mounting groove to which the O-ring can be attached. In this case, the mounting portion may be formed such that the portion where the O-ring engages with the mounting portion is larger than the portion where the O-ring is exposed.

  (14) A guide unit is provided for guiding the connection terminal of the connection portion to the connection terminal provided in the hole.

  According to this, even when the connection terminal is provided in the hole, the connection terminal of the connection portion of the connection cable and the connection terminal can be easily connected. In other words, even in the state where the connection terminal in the hole can not be seen, the connection terminal of the connection cable and the connection terminal can be easily connected. For example, when the connection portion of the connection cable is substantially cylindrical with respect to the substantially cylindrical hole portion, the connection terminal can be easily connected to the connection terminal simply by rotating the connection portion and searching for the guide portion.

  As a guiding means, for example, a protrusion may be provided at the connection portion of the connection cable, and a groove capable of guiding the protrusion toward the terminal to be connected may be provided on the inner wall of the hole. A groove may be provided, and a projection capable of guiding the groove to the connection terminal may be provided on the inner wall of the hole.

  By providing the groove portion in the connection portion of the connection cable, for example, packing such as an O-ring can be easily attached to the connection portion of the connection cable.

  Also, by providing a projection on the inner wall of the hole, for example, when attaching the connection portion of the connection cable to the hole, the connection terminal (for example, male connector) of the connection portion of the connection cable is connected If the connection direction with the terminal (for example, a female connector) is not the same, the tip of the connection portion can contact the projection of the hole, so the connection terminal unnecessarily contacts the connected terminal and is damaged, etc. Can be prevented. In this case, for example, the length of the protrusion may be longer than the length of the connection terminal.

  (15) The guide means is characterized by having a guide protrusion provided in the hole and a guide groove provided in the connection portion.

  According to this, when attaching the connection portion of the connection cable to the hole portion, the connection direction of the connection terminal (for example, male connector) of the connection portion of the connection cable and the to-be-connected terminal (for example, female connector) match In the case where the connection terminal is not in contact, the tip of the connection portion can be in contact with the projection of the hole, so that it is possible to prevent the connection terminal from unnecessarily contacting the connection terminal and damaging or the like. The guide protrusion may be formed to be longer than the length of the connection terminal in the connection direction.

  (16) The connection portion is disposed downstream of the primary insertion portion in which the connection terminal is disposed and the guide groove is formed, and the insertion direction of the primary insertion portion, and the secondary packing on which the predetermined packing is attached And an insertion portion.

  According to this, before the predetermined packing is mounted in the hole, the guide protrusion provided in the hole can be engaged with the guide groove of the connection cable. That is, the guide protrusion and the guide groove can be easily engaged. For example, the connection can be rotated to easily find the guiding projection.

  According to the present invention, it is possible to provide, for example, a compact imaging device that can be attached to a desired attachment location in a state where reflection of the attachment member is prevented, and an imaging system including the same.

  The ring portion 201 can be mounted on the base end side (hereinafter simply referred to as “base end side”) in the central axis A direction of the camera 210, and the camera 210 is relative to the ring portion 201 when the camera 210 is mounted. The diameter of the inner circumferential surface 201b (hereinafter, referred to as "inner diameter") is slightly smaller than the outer diameter of the mounting recess 214 (to be described later, for example, see FIG. 5A) of the camera 210. It is formed to be large. In the present embodiment, the inner diameter of the ring portion 201 is formed to be about 29 mm.

  Further, the diameter of the outer peripheral surface 201 a of the ring portion 201 (hereinafter referred to as “outer diameter”) is such that the outer peripheral surface 201 a of the ring portion 201 and the outer peripheral surface of the camera 210 are substantially coplanar when the camera 210 is mounted. To be positioned, the outer diameter of the outer peripheral surface of the camera 210 is formed to have substantially the same diameter (for example, the same diameter, or a slightly smaller or larger diameter). In the present embodiment, the outer diameter of the ring portion 201 is approximately 33 mm, which is the same diameter as the outer diameter of the outer peripheral surface of the camera 210 (see, for example, FIG. 3A).

  Of the side surfaces 201c and 201d orthogonal to the outer peripheral surface 201a and the inner peripheral surface 201b of the ring portion 201, when the camera 210 is mounted on the ring portion 201, the meshing portion 204 is provided on the side surface 201c that contacts the camera 210. ing. The meshing portion 204 is configured by a plurality of serrated concave portions 204 a and convex portions 204 b formed adjacent to each other in the circumferential direction. On the other hand, nothing is provided on the side surface 201d opposite to the side surface 201c, and it has a substantially planar shape that can be in contact with the fixing member 250.

  As shown in FIG. 4C, the mounting plate 202 is formed in a substantially rectangular plate shape, and when the camera 210 is mounted on the ring portion 201, the camera 210 is arranged along the central axis A in the longitudinal direction. The ring portion 201 is connected to the ring portion 201 via the connection portion 203 so as to extend in a direction away from the lens 231 (for example, see FIGS. 3A to 3C). In the present embodiment, the mounting plate 202 is slightly thinner in the direction away from the lens of the camera 210. The length of the mounting plate 202 in the longitudinal direction is about 39 mm, and the maximum length in the lateral direction Is formed to about 28 mm.

  Further, as shown in FIGS. 4C and 4D, the mounting plate 202 extends along the central axis A with the side surface 201c of the ring portion 201 as the base end, and the shorting at the base end portion of the mounting plate 202. Notches 205a and 205b are provided on both sides in the hand direction. The shape and range of the notches 205a and 205b are set based on the range of the image captured by the camera 210, and in particular, taking into account distortion of the imaging range of the camera 210 caused by the configuration of the optical system or the like. It is set. In the present embodiment, the shapes and ranges of the notch portions 205a and 205b are formed in a substantially rectangular shape in consideration of these, and even when the camera 210 is relatively rotated with respect to the bracket 200, the attachment The board 202 is designed not to be reflected. Further, the notch portion 205 a and the notch portion 205 b are formed to be symmetrical with respect to the central axis A. The end of the mounting plate 202, which is formed by cutting out in a substantially rectangular shape, is formed in an R shape so that the corner is eliminated.

  In a portion of the mounting plate 202 excluding the notches 205a and 205b, a bonding surface 202a to which a double-sided tape for mounting at a mounting location can be attached is provided. That is, the bracket 200 is configured to be attached to the attachment location by affixing the attachment plate 202 to the attachment location with double-sided tape. The affixing surface 202a is formed in a rectangular shape to which a commercially available double-sided tape or the like can be attached. Further, the affixing surface 202a slightly protrudes in the thickness direction of the attaching plate 202 more than the attaching plate 202, so that the attaching place of the double-sided tape on the attaching plate 202 can be easily recognized.

  The adhesion surface 202a has an adhesion area such that the double-sided adhesive tape can exert an adhesive force to such an extent that the bracket 200 attached to the attachment location while supporting the camera 210 does not easily peel off from the attachment location. In the present embodiment, in order to increase the affixing area of the affixing surface 202a, the mounting plate protrudes approximately 10 mm from the base end of the camera 210 in a direction substantially parallel to the central axis A and away from the lens 231. It is a structure. In addition, depending on the adhesive force of the double-sided tape, this protrusion length can also be shortened. By extending the mounting plate 202 in the direction away from the lens 231, it is possible to increase the affixing area of the mounting plate 202 with the proximal end of the mounting plate 202 as close as possible to the lens 231.

  Further, the mounting plate 202 is connected to the ring portion 201 via the connecting portion 203 so as to be symmetrical in the short direction. In other words, when the mounting surface 202 a is viewed from the front, the center of the mounting plate 202 in the short direction is connected to the ring portion 201 via the connecting portion 203 so as to be located on the central axis A. In other words, when the mounting surface 202 a is viewed from the side, the ring portion 201 is connected via the connecting portion 203 so that the center in the short direction of the mounting plate 202 is closest to the ring portion 201 and both sides thereof are symmetrical. (See, for example, FIGS. 2 (e) and (f)).

  The connecting portion 203 is interposed between the ring portion 201 and the mounting plate 202, and the connecting portion 203 is provided with an insertion hole 203a through which a binding band (not shown) can be inserted. The insertion hole 203a penetrates the connection portion 203 substantially in parallel with the circumferential direction of the ring portion 201, and is formed in a substantially rectangular parallelepiped shape so as to allow insertion of a band-like binding band. For example, in the insertion hole 203a, when the bracket 200 is attached to the frame of the forklift, the attachment plate 202 and the frame are collectively wound with a binding band so that the attachment plate 202 is pressed against the frame. It is used when fixing to. That is, the insertion hole 203a plays a role of insurance for enabling the use of the binding band for preventing the drop of the bracket 200.

  By providing the insertion holes 203a, for example, when the camera unit 20 is mounted outside the vehicle, the camera unit 20 can be exposed even when the mounting plate 202 is peeled off from the mounting point of the vehicle by exposing the bracket 200 to weather. It is possible to prevent dropping etc. from the mounting point.

  As shown in FIGS. 5A and 5B, the camera housing 211 is formed in a substantially cylindrical shape having an outer diameter of about 33 mm and a length in the central axis direction of about 50 mm. By making the camera housing 211 into a substantially cylindrical shape, for example, it becomes easy to rotate the camera 210 with respect to the bracket 200, the appearance is also clean, and the size is small and pretty. In addition, for example, even if the camera 210 is rotated, the change in the outer shape is small (for example, basically a substantially cylindrical shape from any point of view), so that it is difficult for the user to feel discomfort or the like.

  A lens arrangement portion 212 in which the lens 231 of the camera module 229 is arranged is provided on the front end side (hereinafter simply referred to as “the front end side”) in the central axis A direction of the camera housing 2111. The lens arrangement portion 212 is a camera housing so that the lens 231 does not protrude beyond the mounting surface 202 a of the mounting plate 202 in the direction in which the lens 231 is orthogonal to the central axis A and in the direction orthogonal to the central axis A. It is formed on the outer peripheral surface 211a of 211 (for example, refer FIG.2 (b) and (c)). In addition, the lens placement portion 212 is provided on the outer peripheral surface 211 a of the camera housing 211 at a substantially central portion in the central axis A direction.

  The outer peripheral surface 211 a of the camera housing 211 is a portion exposed without being hidden by the bracket 200 and the fixing member 250 when the bracket 200 and the fixing member 250 are attached, and in the present embodiment, The length in the central axis A direction is about 30 mm. In addition, the length in the central axis A direction of the portion hidden by the bracket 200 and the fixing member 250 is about 20 mm.

  The lens placement portion 212 is formed with an opening 213 for exposing the lens 231, and as shown in FIG. 6, the lens 231 of the camera module 229 built in the camera housing 211 is from the opening 213. It is exposed through the packing 232. The opening 213 in the present embodiment is formed in a circle having a diameter of about 13 mm. By interposing the packing 232 between the opening 213 and the lens 231 (camera module 229), unnecessary entry of water from the opening 213 is prevented.

  Nothing is provided on the front end side of the lens arrangement portion 212 of the camera housing 211, that is, the front end portion of the camera housing 211 (the front end portion of the camera 210). It is almost flat.

  On the proximal end side of the lens arrangement portion 212 of the camera housing 211, a mounting recess 214 capable of mounting the ring portion 201 of the bracket 200 is provided. The mounting recess 214 has an outer periphery such that when the camera 210 is attached to the ring portion 201 of the bracket 200, the outer peripheral surface 201a of the ring portion 201 and the outer peripheral surface 211a of the camera housing 211 are positioned on the same plane. It is formed in a concave shape with respect to the surface 211a. That is, the mounting recess 214 is formed in a concave shape with respect to the outer peripheral surface 211 a by the thickness of the ring portion 201 of the bracket 200 (about 2 mm in the present embodiment). Further, the outer diameter of the mounting recess 214 is formed to be slightly smaller than the inner diameter of the ring portion 201 of the bracket 200 so that the ring portion 201 of the bracket 200 can rotate on the mounting recess 214.

  At the boundary between the outer peripheral surface 211a and the mounting recess 214, when the ring portion 201 of the bracket 200 is mounted to the mounting recess 214, contact can be made with the side surface 201c of the ring portion 201 (for example, see FIG. 4B). The contact surface 215 is erected in the direction orthogonal to the central axis A. A meshing portion 216 capable of meshing with the meshing portion 204 of the ring portion 201 is formed on a part of the contact surface 215 in the circumferential direction (in the present embodiment, an area of a half circle). The meshing portion 216 is composed of a plurality of concave portions 216 a and a plurality of convex portions 216 b adjacent to each other, and by meshing with any of the plurality of concave portions 204 a and the convex portions 204 b of the meshing portion 204 of the ring portion 201, the camera 210 and the bracket Regulates relative rotation with 200.

  The meshing portion 216 and the meshing portion 204 are formed so as to regulate the rotation at an interval of 5 degrees. By restricting the rotation in steps of 5 degrees, when the camera unit 20 is attached to the vehicle, the orientation of the camera 210 can be adjusted to a desired orientation.

  On the proximal end side of the mounting recess 214 of the camera housing 211, a screw portion 217 is provided, to which the fixing member 250 can be screwed toward the distal end. The screw portion 217 is formed in a concave shape with respect to the mounting recess 214, and at the boundary between the mounting recess 214 and the screw portion 217, a regulating surface 218 that regulates the screwing amount in the axial direction of the fixing member 250 is a central axis. It is set up in the direction orthogonal to A.

  Here, the length in the central axis A direction of the mounting recess 214 is slightly shorter than the length in the central axis A direction of the ring member 21 when the ring portion 201 of the bracket 200 is mounted in the mounting recess 214. Is formed. Therefore, when the ring portion 201 of the bracket 200 is attached to the mounting recess 214, the restriction surface 218 described above is positioned inside the side surface 201d of the ring portion 201. Accordingly, when the fixing member 250 is screwed into the screw portion 217 after the ring portion 201 is mounted in the mounting recess 214, the ring portion 201 is in contact with the fixing member 250 without being restricted by the restricting surface 218. The ring portion 201 can be fixed by being held by the surface 215. At this time, the meshing portion 204 of the ring portion 201 and the meshing portion 216 of the contact surface 215 mesh, and the rotation of the ring portion 201 on the mounting recess 214 is restricted.

  On the other hand, when the screwing amount of the fixing member 250 is reduced, the meshing between the meshing portion 204 of the ring portion 201 and the meshing portion 216 of the contact surface 215 can be released. It is possible to rotate in degrees.

  Further, as shown in FIG. 8C, the male connector 401 has an engaging portion provided on the female connector (in the present embodiment, the female connector 230) of the HDMI in the same manner as the existing HDMI male connector. Engaged engaged portions 401a and 401b are provided.

  In addition, by using the HDMI terminal, the first connection portion 400 can be small and inexpensive, and can arrange more pins. For example, in the case of the USB terminal, only 5 pins can be taken, but by using the HDMI terminal, it becomes possible to arrange pins of 5 pins or more. Further, for example, the thickness of the cord portion 430 can be made thinner by reducing the number of pins as compared to using an existing HDMI cable provided with 12 pins.

  Further, among the pins, a pin for supplying power is also included, and for example, the connection cable 40 supplies power from the device connected to the first connection portion 400 to the device connected to the second connection portion 410. It is possible to supply power from the device connected with the second connection portion 410 to the device connected with the first connection portion 400. That is, the connection cable 40 can supply power in both directions. For example, when the second connection unit 410 is connected to a drive recorder that receives power supply from a cigar socket of a vehicle and the first connection unit 400 is connected to the camera unit 20, the camera unit 20 is connected via the drive recorder. Power supply from the vehicle's cigarette lighter socket.

  The handle portion 405 is a portion which is not inserted into the insertion portion 219 even when the male connector 401 and the female connector 230 are connected, and when the primary insertion portion 403 and the secondary insertion portion 404 are inserted into the insertion portion 219, It is a part that the user grasps. The bellows portion 406 is provided at the proximal end of the first connection portion 400, and is provided to allow flexible movement of the first connection portion 400 and the cord portion 420.

  In the first connection unit 400, the correspondence with the connection target (in the present embodiment, the insertion unit 219) is uniquely identified.

  As shown in FIG. 1, the second connection portion 410 is configured to include an HDMI male connector (hereinafter simply referred to as “male connector”) 411 and a resin-molded mold portion 412. The male connector 411 has the same configuration as that of the male connector 401, and thus the description thereof is omitted. The mold portion 412 is formed in a substantially rectangular shape substantially similar to the HDMI terminal so that the insertion direction of the male connector can be easily understood, as in the connection portion of a general HDMI cable. In addition, the mold portion 412 is not inserted into a connection portion (see, for example, FIG. 9A) 400 of the recording apparatus 30, which will be described later. That is, unlike the first connection portion 400, the second connection portion 410 is configured such that only the male connector 411 is inserted into the connection portion 400.

  There are a plurality of connection cables 40 having different lengths of the cord portion 420. For example, the necessary length according to the distance between the place where the camera unit 20 is provided and the place where the recording device 30 is provided. It is possible to appropriately select one having the code portion 420 of FIG.

  As shown in FIG. 9A, the recording device 30 is formed in a rectangular box shape, and has a plurality of connection portions 300 (four in the present embodiment) to which the second connection portion 410 can be connected, An SD card slot unit 301 in which an SD card is mounted and a microphone unit 302 for recording a sound are configured.

  The female connector 303 to which the male connector 411 of the second connector 410 can be connected is disposed in the connector 300, and the tip of the female connector 303 is exposed. That is, only the male connector 411 is connected to the connection portion 300. In other words, it is configured not to be waterproofed. The SD card slot unit 301 is provided to record an image captured by the camera 210 on the mounted SD card. In the present embodiment, the camera 210 itself does not have a recording medium, and the recording device 30 is configured to perform recording. Thereby, the camera 210 can be miniaturized. The microphone unit 302 is accommodated inside the recording device 30, and can record the voice of the worker, the movement of the work vehicle during work, and the sound of a luggage or the like processed by the work vehicle.

  Further, a sensor unit 5 is connected to the recording device 30, and the sensor unit 5 incorporates an acceleration sensor and a gyro sensor. The sensor unit 5 has a triangle 50 for defining the direction of travel and a horizontal line 51 for defining the horizontal direction. The triangle (progression direction) and horizontal line (direction of travel) for the vehicle actually mounted are It is attached in the state where it is matched with the horizontal direction). By providing a gyro sensor, for example, even in a vehicle that steers with a rear wheel, such as a forklift, a motion of the vehicle (for example, in the case of a forklift, a motion when steering a rear wheel and performing a rotation operation) is detected You will be able to

  Next, a method of using the drive recorder 1 configured as described above will be described with reference to FIGS. 10 to 12. In the following, the case where the drive recorder 1 described above is used by attaching it to the rear glass 101 of the one-box type vehicle 100 and the case where it is used by attaching it to a forklift 110 which is an example of a work vehicle will be described.

  First, the case where it is used by attaching it to the rear glass 101 of the one-box type vehicle 100 will be described with reference to FIG. Here, when the camera unit 20 is connected in advance to the drive recorder attached to the windshield of the vehicle 100 via the connection cable 40 and the camera unit 20 is used as a second camera for photographing the rear of the vehicle This will be described using FIG. 10 is a view showing a state where the camera unit 20 according to the present embodiment is attached to the rear glass 101 of the vehicle 100. As shown in FIG.

  When the camera unit 20 is attached to the rear glass 101, first, the attachment point of the camera unit 20 on the rear glass 101 is determined. Here, when attaching to the rear glass 101, it is necessary to attach to the place which avoided the heat wire 102 arrange | positioned by the rear glass 101. FIG. That is, a place other than the place where the heat wire 102 is disposed is a desired place. In the present embodiment, it is attached to the upper right end of the rear glass 101.

  After the attachment point is determined, next, a connection cable 40 having a length corresponding to the distance between the attachment point and the drive recorder attached to the windshield is prepared. The connection cable 40 may be selected in advance and prepared in accordance with the distance. By using a connection cable of a length corresponding to the required distance, for example, the length of the cord is not insufficient, or the cord is not so long as to be in the way. In particular, the extension of the cord by the connector eliminates the occurrence of a defect such as a loss of image. This is possible because the camera unit 20 and the connection cable 40 are separately configured.

  After preparing the connection cable 40, next, the peeling sheet of the double-sided tape attached to the mounting surface 202a of the mounting plate 202 of the bracket 200 is peeled off so that the central axis A of the ring portion 201 becomes substantially parallel to the horizontal direction. Attach the mounting plate 202 to the rear glass 101. By attaching in this manner, when the camera 210 is supported by the ring unit 201, a wide-angle image in the left-right direction of the vehicle can be taken by the camera 210. For example, the situation of a vehicle traveling in the right and left lanes can be photographed.

  When the mounting plate 202 is attached to the rear glass 101, then the mounting recess 214 of the camera 210 is mounted on the ring portion 201. When the mounting recess 214 is mounted on the ring portion 201, the camera 210 is rotated so that the lens 231 of the camera 210 faces the outside of the vehicle. In the present embodiment, the camera 210 is rotated so that the rear glass 101 and the lens 231 face each other. At this time, for example, even if the camera 210 is rotated 360 degrees, the lens 231 does not contact the mounting plate 202. In addition, even if the camera 210 is made to face the rear glass 101, the lens 231 is not hidden by the mounting plate 202 and can not be photographed. Further, since the connection cable 40 is not connected, the camera 210 can be easily rotated. When the camera 210 is rotated, the fixing member 250 is then screwed into the camera 210 to fix the camera 210 to the bracket 200.

  When the camera 210 is fixed to the bracket 200, next, the first connection portion 400 of the connection cable 40 is connected to the camera 210. Specifically, first, the handle portion 405 of the first connection portion 400 is pinched, and the primary insertion portion 403 is inserted into the insertion portion 219 of the camera 210. When the primary insertion portion 403 is inserted into the insertion portion 219, if the guide protrusion 221 provided on the inner wall of the insertion portion 219 and the guide groove 408 of the primary insertion portion 403 are not engaged, the tip of the primary insertion portion 403 is It abuts on the guide projection 221, and the primary insertion portion 403 can not be inserted any more. That is, when the connection direction of the male connector 401 and the connection direction of the female connector 230 do not coincide with each other, the primary insertion portion 403 can not be inserted more than necessary. At this time, since the length in the insertion direction of the male connector 401 provided at the tip of the primary insertion portion 403 is shorter than the length in the insertion direction of the guide protrusion 221, the male connector 401 and the female connector 230 become unnecessary. There is no chance of contact or damage.

  Next, the user rotates the handle portion 405 while the primary insertion portion 403 is inserted into the insertion portion 219, and engages the guide protrusion 221 with the guide groove 408. At this time, since the handle portion 405 is formed in a substantially cylindrical shape, the user can easily rotate the first connection portion 400. Further, since the first connection portion 400 includes the bellows portion 406, the load on the cord portion 420 due to the rotation can be reduced. At this time, the user may support the camera 210 with the other hand, and since the camera 210 is also formed in a substantially cylindrical shape, it can be easily supported. Furthermore, since the insertion portion 219 is provided at the base end of the camera 210 and the mounting plate 202 of the bracket 200 extends in a direction away from the base end substantially parallel to the central axis A, the first connection portion 400 is rotated. At the same time, even when a force is applied from the base end side in a direction away from the rear glass 101, the mounting plate 202 is not easily peeled off from the rear glass 101.

  When the guide protrusion 221 and the guide groove 408 are engaged due to the rotation of the first connection portion 400, the secondary insertion portion 404 can be inserted into the insertion portion 219. At this time, first, a portion of the secondary insertion portion 404 to which the O-ring 407 is attached is inserted, and when the secondary insertion portion 404 is further pushed from there, the O-ring 407 is crushed and the secondary insertion portion 404 is crushed. Is inserted into the insertion portion 219. By inserting the insertion portion 219 while the O-ring 407 is crushed, the inside of the insertion portion 219 is sealed, and the entry of water or the like is prevented. At this time, since the connection direction of the male connector 401 and the connection direction of the female connector 230 coincide with each other by the guide protrusion 221 and the guide groove 408 being engaged, the guide groove 408 is guided by the guide protrusion 221. , Male connector 401 and female connector 230 are connected.

  When the male connector 401 and the female connector 230 are connected, the second connection portion 410 is then connected to the drive recorder. When the second connection unit 410 is connected to the drive recorder, power is supplied from the drive recorder to the camera 210 via the connection cable 40, and an image captured by the camera 210 can be confirmed on the liquid crystal monitor of the drive recorder. When an image of the camera is displayed on the liquid crystal monitor, the user adjusts the shooting direction of the camera 210 while looking at the liquid crystal monitor. At this time, since the notches 205a and 205b are provided at both ends of the mounting plate 202 of the bracket 200 on the lens side, the liquid crystal monitor can be used even when the camera 210 is faced to the rear glass 101 or when the camera 210 is rotated. The mounting plate 202 will not be reflected.

  Further, since the camera 210 is formed in a substantially cylindrical shape, it is relatively inconspicuous even when attached to the rear glass 101. Further, even when the mounting plate 202 extends in the direction away from the lens 231, the mounting plate 202 does not stand out because the first connection portion 400 is connected to the base end of the camera 210.

  Next, the case where the drive recorder 1 is attached to a forklift 110 and used will be described with reference to FIGS. 11 and 12. FIG. 11 is a view showing a state in which the drive recorder 1 according to the present embodiment is attached to a forklift 110. As shown in FIG.

  As shown in FIG. 11, when the drive recorder 1 is attached to the forklift 110, the camera unit 20 is configured such that the upper frame 111 of the forklift 110 allows the camera unit 20 to simultaneously show the working state by the forklift 110 and the driver driving the forklift 110. Attached to the back of the

  Specifically, first, the release sheet of double-sided tape attached to the attachment surface 202a of the attachment plate 202 of the bracket 200 is peeled off, and the attachment plate is made so that the central axis A of the ring portion 201 becomes substantially parallel to the horizontal direction. 202 is attached to the lower surface 111 a on the rear side of the upper frame 111. By attaching in this manner, when the camera 210 is supported by the ring unit 201, it is possible to take a wide-angle image of the forklift in the left-right direction with the camera 210.

  When the attachment plate 202 is attached to the lower surface 111 a of the upper frame 111, a binding band (not shown) is then inserted through the insertion hole 203 a and wound around the upper frame 111 to press the attachment plate 202 against the upper frame 111. Fix it. Thereby, for example, by exposing the bracket 200 to wind and rain, the bracket 200 is prevented from falling off the upper frame 111 even when the adhesive strength of the double-sided adhesive tape of the mounting surface 202a is reduced.

  When the binding band is wound around the upper frame 111, next, the mounting recess 214 of the camera 210 is attached to the ring portion 201. When the mounting recess 214 is mounted on the ring portion 201, the camera 210 is rotated so that the lens 231 of the camera 210 faces the driver. When the lens 231 of the camera 210 is directed to the driver from the rear of the upper frame 111, the camera and the luggage placed on the claw 113 of the forklift 110 can be simultaneously photographed by the camera 210. Once the rotational position (shooting direction) of the camera 210 is determined, the fixing member 250 is then screwed into the camera 210 to fix the camera 210 to the bracket 200.

  When the camera 210 is fixed to the bracket 200, the recording device 30 is then stored under the sheet 112. By storing the sheet 112 under the sheet 112, the recording device 30 does not get wet with rain. Next, the camera unit 20 and the recording device 30 are connected by a connection cable 40 having a cord length corresponding to the distance between the camera unit 20 and the recording device 30. Specifically, the first connection portion 400 of the connection cable 40 is connected to the camera unit 20, and the second connection portion 410 is connected to the recording device 30. In addition, since the connection of the 1st connection part 400 to the camera unit 20 is the same as that of the above-mentioned, the description is abbreviate | omitted here.

  As described above, when the first connection portion 400 is connected to the camera 210, the inside of the insertion portion 219 is sealed by inserting it into the insertion portion 219 while the O-ring 407 is crushed, so that rain, dust, etc. Is prevented. Therefore, even in a place exposed to wind and rain like the upper frame 111 of the forklift 110, water, dust and the like infiltrate into the camera 210 to prevent the camera 210 from being broken or the like. In the camera 210, the packing 232 is also arranged in the lens arrangement portion 212, and the packing 223 is also arranged between the first housing 211b and the second housing 211c. There is no way to enter. That is, the camera 210 becomes completely waterproof by connecting the first connection portion 400.

  In addition, by using the connection cable 40 having a cord length corresponding to the distance between the camera unit 20 and the recording device 30, the cord becomes unnecessarily long and gets in the way, the cord length becomes insufficient, etc. It is prevented. In particular, in the case of a work vehicle such as a forklift, it is possible to prevent an accident or the like from being caused by an unnecessarily long cord being caught by something.

  When the first connection unit 400 is connected to the camera 210, then the second connection unit 410 is connected to the connection unit 300 of the recording device 30. When the second connection portion 410 is connected to the recording device 30, next, the sensor unit 50 is attached to the seat 112 of the forklift 110. When the front wheel of the forklift 110 is stopped while the rear wheel is steered, the sensor unit 50 may be attached near the location that is the center of rotation. In the present embodiment, the sheet 112 is attached to the lower part. By attaching the lower part of the seat 112, it is possible to make the record of the rotational movement of the forklift 110 close to the feeling of the driver by the rotation of the forklift 110. When the sensor unit is attached, the attachment is completed by connecting the power supply to the recording device 30.

  Next, a reproduction screen in the case where a photographed image photographed by the camera unit 20 attached to the forklift 110 is reproduced by a personal computer or the like will be described with reference to FIG. FIG. 12 is a view showing a photographed image displayed on a liquid crystal monitor using a PC viewer.

  In order to view, on a personal computer, the image photographed by the camera unit 20 and recorded on the SD card of the recording device 30, it is necessary to download a dedicated software to the personal computer. By downloading the dedicated software to a personal computer or the like, it is possible to view the photographed image recorded on the SD card on the personal computer. Hereinafter, a screen on a personal computer projected by dedicated software is called a PC viewer.

  As shown in FIG. 12, the PC viewer is composed of four screens. First, at the upper right, a file list screen 60 in which a file list is displayed is arranged. The file list screen 60 is configured to display a list of files recorded in the SD card. The file list also displays the shooting date, time, and the like.

  Below the file list screen 60, a mounting target display screen 61 is arranged, on which the mounting target to which the camera 210 is mounted is displayed. For example, in FIG. 12, since the camera 210 is attached to the forklift 110, a picture of the forklift is displayed. Further, for example, when the camera 210 is attached to an ordinary automobile, a picture of the ordinary car is displayed, and when attached to a motorcycle, a picture of the motorcycle is displayed. Furthermore, for example, when the camera is mounted on a factory line, a picture of the factory line is displayed. Further, as shown in the attachment target display screen 61, in this picture, the three-dimensional direction and the rotation direction are displayed in X, Y, Z, W.

  On the left side of the file list screen 60, that is, on the upper left of the PC viewer, there is a video screen 62 on which the video of the file selected on the file list screen 60 is displayed. For example, in the case where a video captured with a plurality of cameras is recorded, the video screen 62 can simultaneously display the video captured with each of the cameras. For example, in the case of shooting with four cameras, four screens can be displayed simultaneously. In addition, any one of the four screens can be projected to be larger than the other three, or only the screen of the camera desired to be projected can be projected.

  In addition, on the video screen, up and down reverse, left and right reverse, ○ ° rotation, etc. can be performed by performing predetermined processing (for example, right-click etc. with the cursor placed on the video screen 62). . By performing this operation, it is possible to return the image to the state in which the image is normally viewed, even when the captured image is tilted or reversed depending on the orientation of the camera. Note that once this operation is performed, the state in which the rotation function is reflected is maintained even when other files on the file list are played back.

  Below the video screen 62, the operation state screen 63 of the imaging target (forklift truck 110 in FIG. 12) detected by the acceleration sensor and the gyro sensor is disposed. In the operation state screen 63, the operation of the forklift 110 is displayed by a numerical value and a graph. The user can check the operation of the forklift 110 by looking at the numerical value and the graph.
