Description

  The present invention relates to a recording medium mounting apparatus loaded with a recording medium having a connector such as a removable hard disk, and more particularly to a recording medium mounting apparatus having an autoloading mechanism.

  In recent years, as broadband networks are rapidly spreading, high-performance PCs are becoming cheaper, digital still cameras and digital video cameras are becoming more popular in the home, and broadcasts are being digitized. Digitization of information is progressing. Moreover, in terms of devices that handle information, such as PCs that can record TV and TVs and telephones that can be connected to the Internet, they are entering a new stage beyond conventional categories such as information devices and home appliances.

  Currently, in the field of AV equipment and the like, 3.5 type fixed hard disk drives are used as recording media for recording a large amount of information, but such fixed hard disk drives can cope with a rapidly increasing capacity year after year. It's in a situation that can't be done.

  On the other hand, recent high-density technologies have developed 2.5-inch and 1.8-inch removable hard disk drives (RHDDs) that can sufficiently store large amounts of data.

  In such a removable hard disk, a drive mechanism for rotating the disk and a magnetic head for recording / reproducing are built in the removable hard disk. Therefore, the transfer of signals and the like between a removable hard disk and an external device (recording medium mounting apparatus) loaded with the removable hard disk is generally performed exclusively via a connector.

Therefore, when the removable hard disk is mounted on the recording medium mounting apparatus, the removable hard disk side connector must be mounted on the recording medium mounting apparatus side connector, and when the removable hard disk is removed, the recording medium mounting apparatus side connector is mounted. It is necessary to detach the connector on the removable hard disk side, and such a technique is described in, for example, Patent Document 1 below.
JP-A-4-47554

  However, the magnetic recording apparatus described in Patent Document 1 has the following problems.

  (1) Although the above-mentioned Patent Document 1 includes an eject mechanism for ejecting the removable hard disk to the outside, the operator must perform it manually when inserting the removable hard disk, which is not convenient.

(2) As described above, the removable hard disk large removable hard disk (for example, 2.5 inch, hereinafter referred to as "large disc") and small removable hard disk (e.g., 1.8 inches type, hereinafter "small While such that disk ") has been developed, therefore the size of the case (cartridge) is different depending on the model, easy problem that can not be discharged removable hard disk if it is erroneously inserted is generated.

  That is, when a small disk and a large disk are compared, the vertical dimension (vertical dimension) along the insertion direction of the disk is approximately twice that of the small disk while the large disk is perpendicular to the vertical direction. The horizontal dimension (horizontal dimension) is the same for both discs. For this reason, even if the side surface of the small disk is mis-inserted in the insertion direction (the front surface having the connector is in the lateral direction), it can be inserted into the back via the insertion port. However, since the removable hard disk cannot be driven in the erroneous insertion state as it is, it is necessary to eject the disk to the outside of the insertion slot once and restore the correct orientation, and then reinsert it.

  However, the cartridge in the erroneous insertion state is such that the front and back surfaces provided with connectors face the lateral direction, and the guide plate that guides the disk to the back of the apparatus and the front and back surfaces are opposed to these. A gap is formed between them. For this reason, when the ejecting means described in Patent Document 1, that is, the ejecting roller abuts against one point of the disc and pushes it in the ejecting direction, the orientation of the disc is rotated inside the apparatus, and the disc However, it is difficult to reliably eject the disk.

  The present invention is for solving the above-described conventional problems, and includes a loading mechanism that automatically conveys a recording medium having a connector, and also when a small recording medium is erroneously inserted in an abnormal direction. It is an object of the present invention to provide a recording medium mounting apparatus that can be easily and reliably discharged.

The said loading mechanism, upon insertion of the recording medium is moved in the insertion direction, the moving means to be moved toward the insertion opening is provided at the time of discharge, this movement means, the recording medium, the sides Incorrect insertion that causes the recording medium that is erroneously inserted together with the moving means to be ejected toward the insertion port when it is erroneously inserted into the insertion port in an abnormal state in the insertion direction. A tangent is provided ,
The erroneous insertion contact portion allows the connection between the external connection portion and the internal connector when the recording medium is inserted in a normal state with the front surface facing the insertion direction, and the front surface of the recording medium. Among these, it is formed in the shape which can be contact | abutted to parts other than the said external connection part .

  In the recording medium loading apparatus of the present invention, a recording medium erroneously inserted in an abnormal direction, particularly a small recording medium inserted with the side surface of the cartridge facing the insertion direction can be easily and reliably discharged. .

For example, the erroneous insertion contact portion is a pair of pressed pieces formed on the moving means with a predetermined facing distance in a width direction orthogonal to the insertion direction .

Alternatively, the erroneous insertion contact portion includes a bar extending in the width direction and a pair of leg portions that extend from both ends of the bar to the pair of pressed pieces and are fixed to the pair of pressed pieces. It is a bridging member.

In the above description, the recording medium is inserted in the longitudinal direction, the direction perpendicular to the longitudinal direction is the lateral direction, and the recording medium has the same or shorter length than the lateral length of the recording medium. When the length dimension in the vertical direction is L1 and the width dimension of the external connection portion of the recording medium is W2, the facing distance Wb between the pair of pressed pieces is formed in the range of L1>Wb> W2. Are preferred.

  With the above means, when a recording medium with a normal orientation is inserted, the external connection portion of the recording medium and the internal connector on the apparatus side can be reliably mounted.

  According to the present invention, it is possible to easily and surely take out a recording medium that is erroneously inserted, particularly a small recording medium that is inserted with the side surface of the cartridge facing the insertion direction.

  Two guide elongated holes 82 and 83 extending in the Y direction are formed at both edges in the width direction of the slide means 80, and the guide elongated holes 82 and 83 have guides provided in the moving means 50. The tips of the pins 54 and 55 are inserted. That is, the guide pins 54 and 55 are inserted into the guide long holes 23 a and 23 b of the base chassis 20, and the tips thereof are inserted into the guide long holes 82 and 83 of the slide means 80. Therefore, the slide means 80 is in a state of being able to move linearly in the Y direction in the figure by the guide pins 54 and 55 and the guide long holes 82 and 83. The slide means 80 can move on the surface of the base chassis 20 in the Y direction, and moves in a gap formed between the base chassis 20 and the substrate 39 when moving in the Y1 direction.

  In the vicinity of the guide slot 83, a projecting piece 84 is formed that protrudes from the edge of the slide means 80 in a substantially triangular shape in the X1 direction and is bent in the Z2 direction.

Biting. That is, the moving gear 90 is engaged with the first rack portion 21a and the second rack portion 62 from both sides in the X direction.

  A sliding pin 93 provided on the moving gear 90 is inserted into the sliding groove 12a formed on the surface of the rotating cam 12, and is freely movable in the sliding groove 12a. Yes.

Hereinafter, the operation of the recording medium mounting apparatus 10 will be described.
(initial state)
As shown in FIGS. 4 and 12A, in the initial state before the cartridge 2 of the recording medium 1 is inserted into the insertion slot 111, the rotary cam 12 is rotated the maximum amount in the clockwise direction as described above. The sliding plate 18 is moved to the first closed position in the most Y1 direction. And the front-end | tip of the inclination part 19g of the said door setting part 19A is contact | abutting to the lower part side of the said control convex part 18e, and the operation member 19 is rotated to (alpha) 2 direction with the urging | biasing force of biasing member S4. At this time, the operation pin 19b is positioned at the lower end of the arc groove 11h in the Z2 direction, and the operation pin 19b presses the operation groove 103 of the opening / closing door 100 in the Y2 direction in FIG. It is set to the closed posture rotated about the shafts 101 and 101 in the clockwise direction in FIG. 11 or FIG. 12A.

  4 and 8, the sliding pin 93 of the moving gear 90 is on the Y2 side (side away from the shaft 11a) in the wide portion 12a3 of the sliding groove 12a formed in the rotating cam 12. Is located.

  At this time, as shown in FIG. 8, the moving means 50 and the movable means 60 are moved to the insertion standby position in the Y2 direction shown in the figure in a substantially integrated state by the urging force of the urging member S2. Similarly, the slide means 80 is also moved to the insertion standby position by the urging force of the urging member S3.

  As shown in FIG. 13, as a result of the moving means 50 being moved to the insertion standby position in the initial state, the arm portion 72 of the retracting means 70 is shown in FIG. 13 against the urging force of the urging member S1. And rotated counterclockwise. That is, the locking portion 74 of the retracting means 70 is supported by the support portion 32f in the support hole 32e that climbs the inclined portion 32d of the guide member 30.

  Further, the actuator 17c1 of the third switch member 17c is pressed by the pressing portion 53 of the moving means 50, and the switch state of the third switch member 17c is set to OFF. Therefore, the control unit can detect that the concave portion 2d of the cartridge 2 is not yet locked by the retracting means 70.

  Further, as shown in FIG. 4, the swing member 15 swings counterclockwise, the actuator 17a1 of the first switch member 17a is pressed by the pressing portion 15b, and the first switch member 17a is ON and the second switch member 17b are set to OFF. Therefore, the control unit can detect from the state of rotation of the rotary cam 12 that the moving means 50 is located at the insertion standby position.

(Insertion operation)
In this initial state, when the cartridge 2 of the recording medium 1 is inserted into the insertion port 111 of the nose portion 110, the front surface 2A of the cartridge 2 presses the front surface of the open / close door 100 in the Y1 direction as shown in FIG. 12B. Therefore, the open / close door 100 is set to an open posture rotated toward the inside of the recording medium mounting apparatus. At this time, since the operation pin 19b is pushed by the operation groove 103 and moved in the arc groove 11h in the Z1 direction in the figure, the operation member 19 rotates in the α1 direction against the biasing member S4. The inclined portion 19g of the door setting portion 19A is separated from the control convex portion 18e.

  As shown in FIG. 13, when the cartridge 2 is inserted into the insertion portion 10A through the insertion port 111, both side surfaces 2B and 2B of the cartridge 2 are provided at the guide members 30 provided at both ends in the X direction. It is guided in the insertion direction (Y1 direction) while being sandwiched between the bottom surface 31, the side surface 32, and the top surface 33 of 30.

  When the cartridge 2 is further inserted in the insertion direction, the front surface 2A of the cartridge 2 comes into contact with the bridging member 120, and the moving means 50 provided with the bridging member 120 is pressed in the insertion direction. Therefore, the moving means 50 is moved in the insertion direction together with the cartridge 2 against the urging force of the urging member S3. When the cartridge 2 is inserted, the elastic force of the urging member S3 functions as a damper of the moving means 50, so that the insertion feeling of the recording medium mounting apparatus 10 can be enhanced.

  As described above, the effective width dimension Wa in the X direction of the bar portion 121 of the bridging member 120 is longer than the width dimension W2 of the external connection portion 3 of the cartridge 2 (Wa> W2), and the bar An effective height dimension h in the height direction (Z direction) of the portion 121 is formed to be higher than the height dimension H of the opening 2a of the cartridge 2 (h> H). Therefore, the bridging member 120 can come into contact with a portion of the front surface 2A of the cartridge 2 that avoids the opening 2a provided with the external connection portion 3. That is, in the bridging member 120, the leg portions 122, 122 abut on both side portions 2A1, 2A1 adjacent to the opening 2a, and the bar portion 121 abuts on the upper portion 2A2 of the opening 2a. For this reason, when viewed from the Y2 direction, only the opening 2a of the cartridge 2 can be exposed from a region surrounded by the surface of the base chassis 20 and the bridging member 120.

  Here, when the moving means 50 is moved in the insertion direction, the lower ends of the guide pins 54 and 55 of the moving means 50 cause the Y1 side ends of the guide long holes 63 and 64 of the movable means 60 in the insertion direction. In order to press, the moving means 50 and the movable means 60 are moved in the insertion direction in an integrated state. At this time, the moving gear 90 having the large-diameter pinion gear 91 that meshes with the second rack portion 62 of the movable means 60 is also moved in the insertion direction, but the sliding pin 93 of the moving gear 90 is rotated as described above. Since the cam 12 is located in the wide portion 12a3, the moving gear 90 can be moved in the insertion direction by the width dimension of the wide portion 12a3 (see FIG. 14). Therefore, it is possible to avoid that the damper function by the urging member S3 is hindered by the moving gear 90.

  As shown in FIG. 14, when the moving unit 50 is moved in the insertion direction, the retracting unit 70 is also moved in the insertion direction together with the moving unit 50. When the locking portion 74 of the retracting means 70 moves from the support portion 32f of the guide member 30 and reaches the inclined portion 32d, the retracting means 70 is biased in the clockwise direction in the figure by the biasing member S1. Therefore, the locking portion 74 can descend the inclined portion 32d. However, since the locking portion 74 is supported by the stepped portion 2c provided on the side surface 2B of the cartridge 2 in the initial stage of insertion, the rotation of the retracting means 70 is restricted, and the locking portion 74 has the guide slot 32c. It is regulated so that it cannot reach. Then, when the cartridge 2 is further inserted and the recess 2d provided on the side surface 2B reaches a position where it overlaps the inclined portion 32d of the guide member 30, the retracting member 70 is allowed to rotate. The locking portion 74 descends the stepped portion 2c to reach the guide long hole 32c and locks the concave portion 2d.

  As described above, in the present invention, since the locking portion 74 is lowered in the height direction (Y direction), the concave portion 2d of the cartridge 2 can be locked from the height direction. Compared with the case of stopping, the width dimension of the entire recording medium mounting apparatus 10 can be reduced. Therefore, the width direction of the recording medium mounting device 10 can be reduced particularly.

  At this time, the pressing portion 53 provided on the moving means 50 is disengaged from the actuator 17c1 of the third switch member 17c, so that the switch state of the third switch member 17c is switched from the OFF state to the ON state. Therefore, the control unit on the apparatus main body side detects that the cartridge 2 is inserted into the insertion portion 10A of the recording medium mounting apparatus 10 and the concave portion 2d of the cartridge 2 is locked by the locking portion 74 of the retracting means 70. Is possible.

  Further, when the cartridge 2 is erroneously inserted into the insertion portion 10A in an abnormal state, for example, when the rear surface 2D side of the cartridge 2 is inserted toward the insertion portion 10A, or the cartridge 2 is turned upside down. When inserted in a state, the locking portions 74, 74 of the retracting means 70 cannot lock the recesses 2d, 2d of the cartridge 2. For this reason, the retraction means 70 is not allowed to rotate, and the retraction means 70 is maintained in the state shown in FIG.

  Further, when the cartridge 2 in an abnormal direction is pushed in the insertion direction, the retracting means 70 is slightly moved in the insertion direction in the state shown in FIG. 13, but the locking portion 74 is formed in the support hole 32e. It can abut against the restricting portion 32g and prohibit further movement of the retracting means 70 in the insertion direction. As a result, the pressing portion 53 maintains the pressing state of the actuator 17c1 of the third switch member 17c, and can prevent the switch state of the third switch member 17c from being switched. Therefore, it is possible to prevent the cartridge 2 in an abnormal direction from being automatically conveyed in the insertion direction by a loading operation as will be described later. That is, it is possible to prevent the cartridge 2 in an abnormal orientation from being conveyed to the back of the apparatus.

(Cartridge loading operation)
When the control unit detects that the cartridge 2 is inserted in a normal orientation and the third switch member 17c is switched to the ON state, the control unit starts the drive motor M and causes the rotary cam 12 to move. Rotate counterclockwise.

  When the rotating cam 12 is rotated counterclockwise, the sliding pin 93 provided on the moving gear 90 is moved in the insertion direction along the sliding groove 12a. At this time, the small-diameter pinion gear 92 rolls clockwise while meshing with the first rack portion 21a, so that the moving gear 90 is moved in the insertion direction. Then, the slide means 80 on which the moving gear 90 is mounted is moved in the insertion direction while resisting the biasing member S3.

  At the same time, since the second rack portion 62 that meshes with the large-diameter pinion gear 91 is sent in the insertion direction by the clockwise rotation of the moving gear 90, the movable means 60 having the second rack portion 62 is also inserted. Moved in the direction. When the movable means 60 is moved in the insertion direction, the moving means 50 is pulled in the insertion (Y1) direction via the biasing member S2, so that the moving means 50 is also moved together with the movable means 60 in the insertion direction. . When the moving means 50 is moved in the insertion direction, the cartridge 2 locked by the locking portion 74 of the retracting means 70 mounted on the moving means 50 is automatically set to the recording medium mounting device 10. It is conveyed to the back of the. That is, the rotary cam 12, the moving gear 90, the moving means 50, the retracting means 70, and the like constitute a loading mechanism that conveys the cartridge 2 in the insertion direction.

  The cartridge 2 is moved in the insertion direction with its two side surfaces 2B, 2B being held on the three surfaces of the bottom surface 31, the side surface 32, and the top surface 33 of the guide members 30, 30, but the cartridge 2 is guided. When reaching the back side of the members 30, 30, the guide protrusions 32h, 32h provided on the inner walls of the guide members 30, 30 are inserted into the guide grooves 2b, 2b formed in the side surfaces 2B, 2B. Therefore, the cartridge 2 can be moved in the insertion direction with a more stable posture.

  As shown in FIG. 5, when the cartridge 2 is loaded, the control pin 15 a of the swing member 15 is connected to the outer peripheral end 12 b 1 and the inner peripheral end 12 b 2 in the opening / closing cam portion 12 b of the rotating cam 12. The swing member 15 is set at a neutral position slightly rotated clockwise from the position shown in FIG. Therefore, since the pressing portion 15b is in an intermediate position between the first switch member 17a and the second switch member 17b and neither of them is operated, the control unit confirms that the rotary cam 12 is in a loading state. I can grasp it.

  At this time, the sliding plate 18 is set to the open position slightly moved in the Y2 direction by the locking groove 15c of the swing member 15. Therefore, as shown by a one-dot chain line in FIG. 12B, the control convex portion 18e provided on the sliding plate 18 moves to the position indicated by the solid line in the Y2 direction, and the convex portion 19d of the door setting portion 19A of the operation member 19 is obtained. Lock.

(Connector connection operation)
As shown in FIG. 9, when the slide pin 93 passes the connecting portion 12a4 of the slide groove 12a, the slide pin 93 is moved in the insertion direction by the small arc groove 12a2. As shown in FIG. 10, when the sliding pin 93 reaches the innermost peripheral portion 12a5 of the sliding groove 12a, the front surface 2A of the cartridge 2 that is locked to the retracting means 70 as the sliding pin 93 moves. The connecting portion 42 of the internal connector 40 is inserted into the opening 2a provided in the connector.

  When the external connection portion 3 of the cartridge 2 and the opening portion 43 of the internal connector 40 are attached to each other, an insertion load due to frictional resistance or the like is generated between them. For this reason, even if the movable means 60 meshing with the large-diameter pinion gear 91 of the moving gear 90 moves in the insertion direction, the movement of the moving means 50 provided with the retracting means 70 for locking the cartridge 2 is restricted. The external connection portion 3 and the internal connector 40 are fitted in an incomplete state. However, since the movable means 60 is moved to the mounting completion position, the urging member S2 installed between the movable means 60 and the moving means 50 is extended along with the movement of the movable means 60, The pulling force of the urging member S2 is gradually increased. When the pulling force of the biasing member S2 exceeds the insertion load between the external connecting portion 3 and the internal connector 40, the moving means 50 is moved to the mounting completion position by the pulling force. The connecting portion 3 and the internal connector 40 can be completely fitted.

  When the external connection portion 3 on the cartridge 2 side is completely fitted into the opening 43 of the internal connector 40, each conductive portion 3 a provided in the external connection portion 3 and the opening 43 of the internal connector 40 are inserted. Each provided connection terminal is electrically connected. As a result, digital data can be reproduced and recorded between the recording medium 1 and the main body equipped with the recording medium mounting device 10.

  The opening 2a of the cartridge 2 is exposed from a region surrounded by the surface of the base chassis 20 and the bridging member 120 when viewed from the Y2 direction. The external connector 3 and the internal connector 40 can be securely attached without being obstructed. That is, the bridging member 120 allows the connection between the external connection portion 3 on the cartridge 2 side and the internal connector 40 on the apparatus side when the cartridge 2 is inserted in a normal posture with the front face thereof in the insertion direction. It is formed in the shape to do.

  As shown in FIG. 10, when the mounting (complete fitting) between the external connection portion 3 and the internal connector 40 is completed, the control pin 15 a of the swing member 15 is moved to the inner periphery of the opening / closing cam portion 12 b of the rotating cam 12. In order to enter the end portion 12b2, the swing member 15 is further swung clockwise as shown in FIG. At this time, since the pressing portion 15b of the swing member 15 presses the actuator 17b1 of the second switch member 17b, the control portion has reached the state where the rotation cam 12 has been completely attached to the connector, and the control pin 15a. Can be grasped that the rotation end position which is the inner peripheral end 12b2 has been reached.

  As shown in FIG. 6, when the control pin 15a of the swing member 15 reaches the inner peripheral end (rotation end position) 12b2, the sliding plate 18 is moved to the second closed position in the Y2 direction. Therefore, the control convex portion 18e moves in the Y2 direction, and the concave portion 19e of the door setting portion 19A of the operation member 19 is locked. Thereby, the rotation of the operation member 19 in the α2 direction is allowed. Then, as shown in FIG. 12C, when the cartridge 2 is moved to a position where the external connection portion 3 is attached to the internal connector 40 and the rear surface 2D of the cartridge 2 is separated from the opening / closing door 100, the operation member Since 19 is rotated in the α2 direction by the urging force of the urging member S4, the open / close door 100 is set in the closed posture.

  That is, the outer peripheral end (rotation start position) 12b1 which is one end of the opening / closing cam portion 12b and the inner peripheral end (rotation end position) 12b2 which is the other end close the open / close door 100. A closed groove portion that leads to a posture is formed, and an open groove portion that leads the open / close door 100 to an open posture is formed between the outer peripheral end portion 12b1 and the inner peripheral end portion 12b2. The swing member 15, the sliding plate 18, and the operation member 19 constitute an opening / closing mechanism that opens and closes the opening / closing door 100 between a closing posture and an opening posture.

(Discharge operation)
The discharging operation of the cartridge 2 can be performed by rotating the rotary cam 12 in the clockwise direction. At this time, the rotary cam 12 is moved in the order of FIG. 6 → FIG. 5 → FIG. 4 and FIG. 10 → FIG. Rotated with.

When the rotary cam 12 is rotated slightly clockwise from the state of FIG. 6, it is set to a state in which the control pin 15a has been slightly moved out peripheral side from the inner peripheral end portion (rotation end position) 12b2 The Therefore, since the swing member 15 is slightly rotated counterclockwise, the sliding plate 18 is moved to the open position in the Y1 direction. At this time, for locking the climb convex portion 19d of the inclined portion 19f positioning convex portion 18e from the recess 19e of the door setting portion 19A of the operating member 19 of the sliding plate 18, the opening and closing as shown in FIG. 12 B The door 100 can be set to an open posture.

  At the same time, the sliding pin 93 is moved in the small arc groove 12a2 from the state shown in FIG. 10 to the state shown in FIG. 9, so that the moving gear 90, the sliding means 80, the moving means 50 and the movable means 60 are in the discharge direction (Y2 At the same time, the retracting means 70 and 70 are also moved in the Y2 direction while holding the cartridge 2. Therefore, the external connection part 3 of the cartridge 2 and the internal connector 40 of the recording medium mounting apparatus 10 can be detached.

  When the rotating cam 12 is further rotated in the clockwise direction, the retracting means 70 held by the cartridge 2 are moved to the insertion standby position on the front insertion portion side. At this time, since the open / close door 100 is in the open posture, the rear portion (Y2 side) of the cartridge 2 can be exposed to the outside of the apparatus from the insertion port 111.

Then, as shown in FIG. 4, when the rotary cam 12 is rotated a maximum amount in the clockwise direction, the control pin 15a reaches the outer peripheral end portion (rotation start position) 12b 1, wherein the sliding plate 18 is To reach the first closed position, as shown in FIG. 12A, the control convex portion 18e reaches the tip of the inclined portion 19g from the convex portion 19d of the door setting portion 19A. As a result, the operation member 19 is set in a state in which the opening / closing door 100 can be brought into a closed posture by rotating in the α2 direction by the urging force of the urging member S4. However, in this state, the cartridge 2 is loaded in the insertion port 111, and the opening / closing door 100 is supported on the upper surface of the cartridge 2, so that the closed posture is not caused.

  At this time, the cartridge 2 is moved to the insertion standby position, but as shown in FIG. 13, the locking portion 74 of the retracting means 70 climbs the inclined portion 32d from the guide long hole 32c and reaches the support portion 32f. The locking portion 74 is released from the recess 2d, and the locking of the cartridge 2 is released.

  In this state, the cartridge 2 is stopped with its rear portion exposed to the outside of the apparatus from the insertion port 111. Therefore, the operator can take out the cartridge 2 to the outside by pulling out the cartridge 2 in the Y2 direction.

  When the cartridge 2 is taken out of the apparatus from the insertion port 111, the operation member 19 is rotated in the α2 direction by the urging force of the urging member S4, so that the opening / closing door 100 closes the insertion port 111. Closed posture is set.

  As described above, before the cartridge 2 is inserted into the insertion port 111, after the cartridge 2 is mounted in the apparatus, and after the cartridge 2 is taken out from the insertion port 111, the open / close door 100 is set to the closed posture. Since the insertion port 111 can be closed, it is possible to prevent dust from entering the recording medium mounting apparatus 10.

(Operation when a small disc is inserted in an abnormal direction)
Next, the small disk is in an abnormal direction, that is, in the X direction (X1 direction or X2 direction) in which the front surface of the cartridge 2 (the surface provided with the opening 2a having the external connection portion 3) 2A is lateral. The case where it is inserted in a directed state will be described.

As shown in FIG. 1, the vertical dimension L1 of the small disk is the same as or shorter than the horizontal dimension W1 (W1 ≧ L1). For this reason, in the state where the front surface 2A of the cartridge 2 of the small disk is directed to the side (X direction), that is, in the state where the side surface 2B of the cartridge 2 is directed to the insertion direction (Y1 direction), It is possible to insert into.

Here, the effective width Wa in the X direction of the bar portion 121 of the bridging portion member 120 as described above that are shorter than the longitudinal dimension L1 of the small disk (L1> Wa). For this reason, a small disk inserted in an abnormal direction can always have the side surface 2B of the cartridge 2 in contact with the bridging member 120.

Therefore, even if a small disk in an abnormal direction is inserted from the insertion port 111, the bridging member 120 is pushed in the insertion direction by the side surface 2B of the cartridge 2, so that each of the third switch members 17c is similar to the above. The switch state changes . For this reason, the loading mechanism is actuated to move the transfer means 50 in the insertion direction.

However, even when the loading mechanism reaches the conveyance end state shown in FIG. 10, the external connection portion 3 of the small disk and the internal connector 40 do not fit, so the space between the small disk and the device main body is not. Thus, communication such as data signals is not performed. Therefore, the control unit on the apparatus main body side can recognize that a disc having an abnormal orientation has been inserted into the recording medium mounting apparatus 10 at least at this time.

  As described above, the control unit causes the loading mechanism to perform an operation opposite to the operation at the time of insertion, that is, an operation of discharging the small disc cartridge 2 by rotating the rotating cam 12 clockwise. As a result, the moving gear 90, the sliding means 80, the moving means 50, and the movable means 60 are moved in the Y2 direction, which is the discharging direction.

  At this time, since the bridging member 120 provided in the moving means 50 abuts on the small disk and presses the small disk in the ejecting direction, the small disk in the abnormal direction is removed. It is possible to move to the insertion port 111 along the discharge direction (insertion port direction). Moreover, since the bridging member 120 has a bar shape, the entire bar portion 121 can abut against the side surface 2B of the small disk. For example, the side surface 2B of the small disk moves in the moving direction (Y direction). Even when it is tilted with respect to the X direction orthogonal to the side surface 2B, the side surface 2B can be restored to a state along the X direction while moving. For this reason, even a small disk in an abnormal direction can be reliably removed from the insertion slot 111. In other words, the bridging member 120 functions as an erroneous insertion contact portion that moves a small disk that has been erroneously inserted in the ejecting direction and pushes it out of the insertion port 111.

  FIG. 16 is a front view of a moving member similar to FIG. 15 showing another embodiment of the erroneous insertion contact portion. In this embodiment, the pair of pressed pieces 52a and 52a function as an erroneous insertion contact portion.

  That is, the pair of pressed pieces 52a, 52a shown in this embodiment is formed such that the opposing distance Wb in the X direction is wider than the width dimension W2 of the external connection portion 3, and the vertical dimension of the small disk. It is formed to be shorter than L1 (L1> Wb> W2).

  For this reason, when a normally oriented disk (a large disk and a small disk) is inserted in the same manner as described above, the pair of pressed pieces 52a and 52a are formed with the opening in the front surface 2A as shown in FIG. It is possible to avoid the portion 2a and abut against both side portions 2A1, 2A1 adjacent thereto. The small disk is transported in the insertion direction in the state shown in FIG. 17, but when the transport end state (see FIG. 10) is reached, the opening 2a is the one when viewed from the Y2 direction. Since it is in the state exposed from the area | region enclosed by the to-be-pressed piece 52a and the other 52a, mounting | wearing with the said external connection part 3 and the internal connector 40 is not interrupted by said pair of to-be-pressed piece 52a, 52a. It is possible to allow and reliably connect the two.

  Further, when a small disk is inserted in an abnormal direction as described above, the pair of pressed pieces 52a and 52a can come into contact with the side surface 2B of the cartridge 2, so that the loading mechanism is similar to the above. In operation, the moving means 50 is moved in the insertion direction, and it is recognized by the control unit on the apparatus main body side that a disk with an abnormal orientation has been inserted.

  Then, when the loading mechanism is operated in the reverse direction by the control unit as described above, the moving gear 90 is moved in the Y2 direction which is the discharging direction. At this time, the pair of pressed pieces 52a, 52a Can be brought into surface contact with the side surface 2B of the disc at two places on the left and right sides in the width direction (X direction). Therefore, even when the side surface 2B of the small disk is inclined with respect to the X direction orthogonal to the moving direction (Y direction), the side surface 2B is moved along the X direction (normal posture) while moving. It can be redirected, and a small disk that is in an abnormal direction can be reliably conveyed toward the insertion slot 111.

  That is, the pair of pressed pieces 52 a and 52 a shown in FIG. 17 also function as an erroneous insertion contact portion that moves a small disc that has been erroneously inserted in the ejecting direction and pushes it out of the insertion port 111.

  As described above, in the present invention, the erroneously inserted small disk can be surely discharged by the erroneous insertion contact portion having a simple configuration of the bridging member 120 and the pair of pressed pieces 52a and 52a. It is.

  In the above embodiment, the description has been given using the removable hard disk as the embodiment of the recording medium having the connector. However, the present invention is not limited to this, and for example, in the cartridge 2 instead of the magnetic disk. A recording medium incorporating an IC memory may be used.
