Description

  The present invention relates to an image recording apparatus capable of recording (printing) data such as images and characters on a plurality of types of recording media, and more particularly to a configuration including a manual feed tray on the back side of the apparatus main body of the image recording apparatus. It is.

  Conventionally, a single-function image recording apparatus such as an ink jet type or laser type printer, copying apparatus, facsimile machine, etc., a multifunctional image recording apparatus having a printer function, a copy function, a scanner function, and a facsimile function. A recording medium having a manual feed tray that can manually supply a recording medium such as the above to the apparatus main body is known.

  Among them, the image recording apparatus described in Patent Document 1 includes an image reading device that reads document data and the like in the upper part of the apparatus main body (housing), and a recording medium such as paper is deposited and accommodated in the lower part of the apparatus main body. A paper feeding cassette is arranged, and the recording medium is conveyed to the upper image recording unit via the U-turn path and discharged from the front opening of the apparatus main body, while the manual recording medium is supplied to the image recording unit. A configuration is disclosed in which a first manual feed tray is attached to the back side of the apparatus main body with an inclination so that the base end is downward, and a recording medium related to manual feed is discharged from a front opening.

  On the other hand, in the image recording apparatus described in Patent Document 2, in addition to the above configuration, a second manual feed tray on which a third recording medium such as a DVD is placed is supplied from the front opening of the apparatus body. 3 discloses a configuration in which an image is recorded on the surface of a recording medium by the image recording unit and then returned to the front opening.

  However, in the configurations of Patent Documents 1 and 2, since the first manual feed tray is provided in a fixed posture with respect to the apparatus main body, the first manual feed tray is provided on the back side of the apparatus main body even when the first manual feed tray is not used. Therefore, there is a problem that a large space for the image recording apparatus needs to be provided, and the installation space for the image recording apparatus becomes large.

  In order to solve the above problem, the first manual feed tray can be folded upward from the inclined posture so as to be flush with the back surface of the apparatus main body, with the lower end side support shaft (hinge portion) as the center. What has been constructed is proposed and publicly known.

JP 2001-39557 A (see FIG. 1) JP 2006-91947 A (see FIG. 3)

  By the way, when using the first manual feed tray, the placement length of the recording medium placed on the first manual feed tray in the supply direction (the length from the support shaft toward the free end of the first manual feed tray) is as large as possible. Therefore, there is a demand for stabilization, and an auxiliary tray is attached to the first manual feed tray so as to be extendable or foldable. Further, when configured as described above, since the free end side of the first manual feed tray can be observed from the upper front side of the apparatus main body during use, it is easy to check the manual feed operation.

  However, in the configuration in which the first manual feed tray is folded upward when not in use, the rear of the apparatus main body is recessed with a storage portion having a large height so that the first manual feed tray itself can be stored above the support shaft. Must. On the other hand, the image recording unit of the image recording apparatus is provided at a high position in the apparatus main body, and the recording medium for manual feeding must be supplied substantially horizontally toward the image recording apparatus. The position is necessarily high. Therefore, it is necessary to increase the back side dimension of the apparatus main body above the support shaft for the storage portion.

  On the other hand, there is a demand for a more compact image recording apparatus, and the height of the apparatus main body tends to be lower. In particular, in a model having an image reading device on the upper side of the apparatus main body, the image reading apparatus is often connected via a hinge so as to be openable and closable with respect to the upper surface of the apparatus main body for maintenance. It is practically difficult to form the storage section across the image reading apparatus side. In this case, there is a problem that the height of the apparatus main body becomes larger and bulky.

  In order to solve this problem, the present applicant has proposed that the first manual feed tray is rotated downward and stored in the storage space on the back side of the apparatus main body.

  Further, as in Patent Document 2, the second manual feed tray is supplied from the front opening of the apparatus main body, the image is recorded on the surface of the third recording medium by the image recording unit, and then returned to the front opening. Since the image recording unit is provided on the side close to the back surface of the apparatus main body, the setting unit for the third recording medium in the second manual feed tray is set to the back side of the second manual feed tray. The image recording operation to the label recording area of the third recording medium becomes easy. In this case, in order to meet the demand for shortening the depth dimension of the apparatus main body, the present applicant has proposed that the tip on the back side of the second manual feed tray protrudes outward from the back surface of the apparatus main body.

  Then, if the user turns the first manual tray that is inclined upward without being aware of the second manual feed tray that protrudes from the back of the apparatus main body in a substantially horizontal state, both manual feed trays Interfered with each other, resulting in problems such as a label recording failure of the third recording medium and a problem that the manual feed tray is damaged.

  The present invention has been made to solve the above-described problem, and in addition to a configuration that can be stored in the storage space on the back side of the apparatus main body by rotating the upwardly inclined first manual feed tray downward, A second manual feed tray on which a third recording medium such as a DVD is placed is supplied from the front opening of the apparatus main body, and the image recording unit records an image on the surface of the third recording medium, and then the front opening. An object of the present invention is to provide an image recording apparatus capable of preventing the interference between the first manual feed tray and the second manual feed tray in the configuration of returning to the above.

  In order to achieve the above object, according to the image recording apparatus of the first aspect of the present invention, a back surface opening is provided on the back surface of the apparatus body including the image recording section, and the back surface side end of the apparatus body is provided. The first manual feed tray provided with a mounting plate for feeding the manually fed recording medium to the first conveyance path for the image recording unit is rotated up and down by a hinge provided on the upper side of the rear opening. The second manual feed tray, which is connected in such a manner that the recording medium is placed, can move forward and backward from the front opening to the first conveyance path, and a part of the second manual feed tray can be moved from the rear opening to the outside of the apparatus main body. The first manual feed tray when used is in an obliquely upward posture on the outside of the back surface of the device main body, and the first manual tray is in a downward posture when not in use and the device main body on the back side when not in use. Inside rear storage empty Further, the first manual feed tray has a gate body that is adjacent to the mounting plate on the side close to the hinge portion and is rotatable in parallel with the mounting plate. When the first manual feed tray rotates downward in the rear side storage space direction, the gate body comes into contact with the second manual feed tray protruding outside the apparatus main body. It is configured to be evacuable.

  According to a second aspect of the present invention, in the image recording apparatus according to the first aspect, the rotating shaft portion of the gate body is provided on the side adjacent to the mounting plate.

  According to a third aspect of the present invention, in the image recording apparatus according to the first or second aspect, the protrusion amount of the second manual feed tray from the back opening to the outside of the apparatus main body is the amount of the first manual feed tray. This is smaller than the maximum protrusion amount to the outside of the apparatus main body when rotating between use and non-use.

  According to a fourth aspect of the present invention, in the image recording apparatus according to any one of the first to third aspects, a first upper body is provided at an upper part of the main body of the apparatus and is provided at a rear side end of the main body of the apparatus. It is provided so that it can be opened and closed up and down via a hinge part.

  According to a fifth aspect of the present invention, in the image recording apparatus according to any one of the first to fourth aspects, the contact plate of the side guide provided on the first manual feed tray is high toward the second hinge portion. The side guide is configured to be retractable at the same time in the retracted region of the gate body.

  According to the first aspect of the present invention, the first manual feed tray has a direction in which the gate body is rotatable adjacent to the placement plate on the side close to the hinge portion and parallel to the placement plate. When the first manual feed tray pivots downward in the direction of the rear side storage space, the gate body comes into contact with the second manual feed tray projecting out of the apparatus main body and can be retracted. Therefore, the first manual feed tray can be stored in the back side storage space on the back side of the device body when not in use without increasing the height of the device body, and the image recording device can be made compact. There is an effect that can be formed. When the first manual feed tray is set to the use state, the free end side of the first manual feed tray comes closer to the upper surface of the upper main body, so that the user from the upper front side of the apparatus main body can easily see. Play.

  In the first aspect of the present invention, the first manual feed tray is arranged on the side close to the hinge portion, adjacent to the mounting plate, in a direction in which the gate body is rotatable and parallel to the mounting plate. When the first manual feed tray pivots downward in the rear side storage space direction, the gate body contacts the second manual feed tray protruding from the back opening to the outside of the apparatus main body. Since the first manual feed tray and the tip of the second manual feed tray do not interfere with each other, the second manual feed tray during label printing does not move carelessly because it is configured so as to be able to contact and retract. Inconveniences such as label printing defects can be avoided.

  According to the second aspect of the present invention, since the rotation shaft portion of the gate body is provided on the side adjacent to the mounting plate, when the first manual feed tray rotates, The distance away from the manual feed tray can be increased.

  According to a third aspect of the present invention, a part of the second manual feed tray is configured to be able to protrude out of the apparatus main body from the back opening, and from the back opening to the outside of the apparatus main body. The protrusion amount of the second manual feed tray is smaller than the maximum protrusion amount to the outside of the apparatus main body when the first manual feed tray is rotated between the use time and the non-use time.

  Therefore, if the horizontal gap between the rear surface of the image recording apparatus 1 and other objects such as a wall of the room is set slightly larger than the maximum protruding amount at the installation position of the image recording apparatus, the front end of the second manual feed tray will be used later. It is possible to ensure that other objects do not get in the way when protruding, and that label printing by the second manual feed tray does not hinder.

  According to the fourth aspect of the present invention, the upper body is provided on the upper part of the apparatus body so that the upper body can be opened and closed through a first hinge provided at the rear side end of the apparatus body. Therefore, even when the upper main body is opened and rotated around the first hinge portion in the state where the first manual feed tray is stored in the rear side storage space, the upper main body and the first manual feed are provided on the rear side of the apparatus main body. There is an effect that the tray does not interfere with each other.

  According to the fifth aspect of the present invention, the contact plate of the side guide provided on the first manual feed tray is formed so that the height thereof decreases toward the second hinge portion. Therefore, when the first manual feed tray stored in the back side storage space is rotated to the use state, the user picks the lower end side (free end side) of the first manual feed tray on the contact plate of the side guide. Thus, the first manual feed tray can be easily rotated. Further, if a part of the contact plate of the side guide is configured to be retractable together with the gate body, the first manual feed tray is changed from the use state to the non-use state while the interval between the pair of contact plates is reduced. There is an effect that the posture can be changed.

  The side guide 33 includes a pair of sliders separated in the width direction, and both side edges in the width direction of the recording medium perpendicular to the feeding direction of the recording medium that is erected on each slider and placed on the mounting plate 32. And a rack bar 38 extending in the width direction from each slider, and a pinion 39 rotatably provided on the lower surface of the mounting plate 32 and meshing with both rack bars 38. It has been. Since the contact plate 37 is formed so that the height from the placement plate 32 increases toward the free end side of the arm 31, conversely, the contact plate 37 faces the second hinge portion 34. Since the height of the contact plate 37 is low, the user has a function as a knob that is easy to operate by gripping the contact plate 37 with a finger.

  When the user picks one of the contact plates 37 with his / her finger and moves it in the width direction of the recording medium, the distance between the pair of contact plates 37 can be displaced in the wide and narrow direction. In addition, it has the locking member (both not shown) which is provided in the lower surface of a slider and can displaceably disengage with the engagement tooth formed in the back surface of the mounting board 32. As shown in FIG. Accordingly, the position of the pair of contact plates 37 can be held in a state where the distance between the pair of contact plates 37 is a desired value.

  The back plate 2 c of the housing 2 is provided with a back opening 51, and a storage space 50 is formed between the back opening 51 and the back side of the U-turn transport unit 18. In this storage space 50, the first manual feed tray 30 can be stored with its free end facing downward. In the first embodiment, the second hinge portion 34 is a portion closer to the upper portion of the rear opening 51 and is located slightly higher than the standard height of the first transport path 19 and below the first hinge portion 6. Is set. Accordingly, the first manual feed tray 30 when used is in an obliquely upward position on the outside of the back surface of the housing 2 (see the solid line state in FIG. 6). In such a downward posture, it can be stored in the back side storage space 50 (see the solid line state in FIG. 4A). In this case, it is assumed that the entire side guide unit 33 in the first manual feed tray 30 is also stored in the back side storage space 50. The first manual feed tray 30 is provided with stopper means (not shown) that can maintain an inclined posture during use.

  According to the above configuration, the first manual feed tray 30 can be stored in the back side storage space 50 on the back side of the housing 2 when not in use, without increasing the height dimension of the housing 2. When the manual feed tray 30 is set to the use state, the first manual feed tray 30 free end side comes closer to the upper surface of the upper body 3, so that the user from the upper front side of the housing 2 can easily see. Further, even when the upper main body 3 is opened and rotated around the first hinge portion 6 in the state where the first manual feed tray 30 is stored in the rear side storage space 50, The first manual feed tray 30 does not interfere with each other. Further, when the first manual feed tray 30 stored in the back side storage space 50 is rotated to the use state, the user places a tall part of the contact plate 37 (the lower end side of the first manual feed tray 30 (free side It is easy to rotate the first manual feed tray 30 by gripping the end side.

  3 and 4A show a configuration of a second manual feed tray (also called a label belt) capable of label printing on the surface of an optical disk such as a CD-R or DVD as an example of a third recording medium. This will be explained based on.

[Configuration of the second manual feed tray]
FIG. 3 is a schematic perspective view of the second manual feed tray 45. On the surface of the second manual feed tray 45 made of a synthetic resin material, an optical disk 46 such as a CD-R or DVD as an example of a third recording medium is provided. A circular groove 47 that can be set is formed as a recess. A convex portion 47 a that fits in the central hole 46 a of the optical disk 46 has the same height as the depth of the circular groove 47 in the central portion of the circular groove 47 having the same diameter as the optical disk 46. Further, the surface of the optical disk 46 becomes a label printing area 46 b where a label such as a title can be printed and recorded by the image recording unit 12. On the other hand, the back surface of the optical disk 46 is a data recording area for images and music.

  In the housing 2, on the front opening 2 a side, the second manual feed tray 19 is supported in the width direction of the second manual feed tray 45 on which the optical disk 46 is set, along the first transport path 19 in the direction of the image recording unit 12. An auxiliary conveying means 48 for conveying 45 is provided (see FIG. 4A).

  At the preparation position where the second manual feed tray 45 is not set, the auxiliary transport means 48 is stopped in the housing and close to the front opening 2a side. When a tray set command is input to the image recording apparatus 1, the auxiliary conveyance means 48 is slightly lowered and partially exposed forward from the rear front opening 2a. In this state, the second manual feed tray 45 on which the optical disk 46 is set is placed on the auxiliary transport means 48. Next, when a label printing preparation command is issued, the auxiliary conveying means 48 moves so as to approach the recording unit 12. At this time, the driving roller and the driven roller (spur roller) of the registration roller pair 27 and the discharge roller pair 28 are moved. And the second manual feed tray 45 is inserted into the gap. Next, the gap between the drive roller and the driven roller (spur roller) is narrowed so that the second manual feed tray 45 is sandwiched between the upper and lower rollers, and the tip of the second manual feed tray 45 is moved by the reverse rotation of the two drive rollers. It can be conveyed at the same height level as the first conveyance unit 19 from the rear opening 51 of the housing 2 to a preparation position that protrudes outside by an appropriate dimension L1 (see FIG. 4). Thereafter, when a label printing command is issued, printing recording is performed on the label printing area 46b of the optical disk 46 on the second manual feed tray 45 while the two driving rollers intermittently rotate forward.

  The dimension L1 at which the tip of the second manual feed tray 45 projects outward from the rear opening 51 of the housing 2 at the preparation position is the first dimension when the first manual feed tray 30 is rotated upward from the storage position to the use position. It is set to be smaller than the maximum protruding amount at the front end of the one manual feed tray 30 and smaller than the protruding amount at the front end of the first manual feed tray 30 in the upward inclined posture during use (see FIG. 6).

  By setting in this way, if the horizontal gap dimension between the back surface of the image recording apparatus 1 and another object such as a room wall is slightly larger than the maximum protruding amount at the installation location of the image recording apparatus 1, When the tip of the second manual feed tray 45 is protruded later, other objects do not get in the way, and it can be ensured that the label printing by the second manual feed tray 45 does not hinder.

  Further, as shown in FIG. 5, in the first manual feed tray 30, a dimension H2 from the rotating shaft portion 42 side of the gate body 40 to the edge 40a on the side close to the second hinge portion 34, and a pair of first from the edge 40a. 2 The dimension H1 of the gap 36 formed between the rotation axis 35 connecting the hinge portions 34 is set appropriately, and the width dimension of the gate body 40 between the pair of arms 31 is set to the width of the second manual feed tray 45. By setting the size larger than the dimension, when the first manual feed tray 30 is moved from the upward inclined posture at the time of use to the downward rotation stored in the back side storage space 50, the tip of the second manual feed tray 45 is moved to the gate body 40. The gate body 40 is retracted and rotated so as to move away from the tip of the second manual feed tray 45 against the biasing force of the resilient biasing means, and the tip of the second manual feed tray 45 passes through the gap 36. Easy Since it (see the two-dot chain lines in FIG. 6), the second bypass tray 45 in the label printing is not inadvertently moved, it is possible to avoid a disadvantage such as label printing defects.

  In addition, when the height position of the 2nd hinge part 34 is the same as the height level of the 1st conveyance part 19, and when the height position of the 2nd hinge part 34 is lower than the height level of the 1st conveyance part 19 However, if the dimension H1 of the gap 36 and the height dimension H2 of the gate body 40 are set appropriately, the second manual feed tray 45 is protruded from the rear surface of the housing 2 in the same manner as described above. The one manual feed tray 30 can be changed from the use state to the non-use posture.

  In the state where the tip of the second manual feed tray 45 protrudes outward from the back opening 51 of the housing 2, it is prohibited to rotate the first manual feed tray 30 stored in the back side storage space 50 upward. . And in the 1st manual feed tray 30 accommodated in the back side storage space 50, since the gate body 40 and the mounting plate 32 are hold | maintained on the same plane by the elastic biasing means and the stopper body 43, the gate body 40 is shown. Only does not protrude outward from the rear opening 51 of the housing 2.

  In the posture when the second manual feed tray 45 is used, the recording medium placed on the mounting plate 32 and the gate body 45 is smoothly guided from the inclined second transport unit to the registration roller pair 27. It is preferable to provide an auxiliary horizontal guide plate 49 (see FIGS. 4 and 6) that extends from the upper end of the U-turn transport unit 18 toward the rear opening 51.

  FIG. 7A and FIG. 7B show a second embodiment of the side guide 33. In this embodiment, a part 37b of the contact plate 37 in the side guide 33 is provided so as to be rotatable with respect to the main body 37a via a pin 44. When the interval between the pair of contact plates 37 is narrowed, a part 37 b can contact the gate body 40. Therefore, if the free end side of the gate body 40 is rotated so as to be lifted with respect to the mounting plate 32, the gate body 40 is pushed and a part 37 b is bent with respect to the body 37 a around the location of the pin 44. (See FIG. 7B). That is, as shown in FIG. 6, when the gate body 40 is pushed and retracted at the tip of the second manual feed tray 45, a part 37b of the abutting plate 37 of the side guide 33 can also be retracted. The first manual feed tray 30 can be changed from the use state to the non-use posture while the interval between the contact plates 37 is narrowed.

  As another embodiment, the first manual feed tray 30 may be provided with an auxiliary placement plate (not shown) for supporting the rear side of the recording medium so as to be extendable and foldable.

  Needless to say, the present invention can be applied not only to the multi-function type image recording apparatus 1 but also to a single-function type image recording apparatus that does not include the upper body 3. An effect can be produced.
