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 member 80. Therefore, the slide member 80 can be moved in the Y direction in the figure by the guide pins 54 and 55 and the guide long holes 82 and 83. The slide member 80 can move on the surface of the base chassis 20 in the Y direction, and moves in the gap 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 from the edge of the slide member 80 in a substantially triangular shape in the illustrated X1 and bent in the Z2 direction. The protruding piece 84 is inserted into a long hole 24 formed in the base chassis 20, and the tip thereof reaches the lower surface of the base chassis 20. A hooking portion 85 is formed at the tip of the protruding piece 84, and a coil spring or the like is formed between the hooking portion 85 and the hooking portion 26 provided at a position in front of the base chassis 20. The urging member (second urging member) S3 is installed in a compressed state. Therefore, the slide member 80 is always urged forward (Y2 direction in the drawing) on the base chassis 20.

  In a state where the slide member 80 is mounted on the surface of the base chassis 20, the small-diameter pinion gear 92 of the moving gear 90 meshes with the first rack portion 21 a formed in the opening hole 21 of the base chassis 20. ing. Further, the large-diameter pinion gear 91 of the moving gear 90 enters the opening hole 51 of the moving member 50 and the opening 61 of the movable member 60, and the second rack portion 62 provided on the movable member 60 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 first sliding groove 12a formed on the surface of the cam member 12, and freely moves in the first sliding groove 12a. It is possible to move to.

Hereinafter, the operation of the recording medium mounting apparatus 10 will be described.
(initial state)
5 and 6 show an initial state before the hard disk is inserted, FIG. 5 is a plan view of the recording medium mounting device, and FIG. 6 is a side view showing an enlarged front portion of the recording medium mounting device. .

  As shown in FIG. 5, the cartridge 2 of the recording medium 1 is inserted into the insertion portion 10 </ b> A of the recording medium mounting apparatus 10 surrounded by the inclined surfaces 31 a, 32 a, 33 a formed on the pair of guide members 30, 30. In the previous initial state, the cam member 12 is rotated clockwise in FIG. For this reason, the sliding pin 93 of the moving gear 90 is located on the Y2 side (the side away from the shaft 11a) in the wide portion 12a3 of the first sliding groove 12a formed in the cam member 12. .

  At this time, the moving member 50 and the movable member 60 are moved to a front position in the Y2 direction in a substantially integrated state by the urging force of the urging member S2. Similarly, the slide member 80 is also moved to the front insertion portion side position (insertion standby position) by the urging force of the urging member S3.

  As shown in FIG. 6, in the initial state, as the moving member 50 is moved to the insertion standby position, the arm portion 72 of the retracting member 70 resists the urging force of the urging member S1 in FIG. It is rotated counterclockwise. That is, the locking portion 74 of the retracting member 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 17a1 of the first switch member 17a is pressed by the pressing portion 53 of the moving member 50, and the switch state of the first switch member 17a is set to OFF. Therefore, the control unit can detect that the recess 2 d of the cartridge 2 is not yet locked by the retracting member 70.

  Further, as shown in FIG. 5, the swing member 15 swings counterclockwise, the actuator 17b1 of the second switch member 17b is pressed by the pressing portion 15b, and the second switch member 17b is ON and the third switch member 17c are set to OFF. Therefore, the control unit can detect from the rotation amount of the cam member that the moving member 50 is located at the insertion standby position.

(Insertion operation)
In this initial state, the cartridge 2 of the recording medium 1 is inserted into the insertion portion 10A. When the cartridge 2 is inserted into the insertion portion 10A, both side surfaces 2B, 2B of the cartridge 2 are placed between the bottom surface 31, the side surface 32, and the top surface 33 of the guide members 30, 30 provided at both ends in the X direction. It is guided in the insertion direction (Y1 direction) while being sandwiched.

  When the cartridge 2 is further inserted in the insertion direction, the front surface 2A of the cartridge 2 comes into contact with the pressed portions 52a and 52a provided on the moving member 50, and the moving member 50 is biased by the biasing member S3. The cartridge 2 is moved together with the cartridge 2 in the insertion direction. When the cartridge 2 is inserted, the elastic force of the urging member S3 functions as a damper of the moving member 50. Therefore, it is possible to provide the recording medium mounting apparatus 10 with an enhanced insertion feeling and excellent operability.

  Here, when the moving member 50 is moved in the insertion direction, the lower ends of the guide pins 54 and 55 of the moving member 50 cause the Y1 side ends of the guide long holes 63 and 64 of the movable member 60 in the insertion direction. In order to press, the moving member 50 and the movable member 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 member 60 is also moved in the insertion direction. Since it is located in the wide part 12a3 of the member 12, it is possible to move the inside of this wide part 12a3 in the insertion direction (see FIG. 7). 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. 7, when the moving member 50 is moved in the insertion direction, the retracting member 70 is also moved in the insertion direction together with the moving member 50. When the engaging portion 74 of the retracting member 70 moves from the support portion 32f of the guide member 30 and reaches the inclined portion 32d, the retracting member 70 is urged clockwise in the figure by the urging 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 at the initial stage of insertion, the rotation of the retracting member 70 is restricted, and the locking portion 74 has the guide long hole 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.

  Thus, in this invention, since the recessed part 2d of the cartridge 2 can be latched when the latching | locking part 74 descend | falls to a height direction (Y direction), when latching the cartridge 2 from a horizontal direction In comparison, the overall width of the 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, since the pressing portion 53 provided on the moving member 50 is disengaged from the actuator 17a1 of the first switch member 17a, the switch state of the first switch member 17a 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 drawing member 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 member 70 cannot lock the recesses 2d, 2d of the cartridge 2. Therefore, the retraction member 70 is not allowed to rotate, and the retraction member 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 member 70 is slightly moved in the insertion direction in the state shown in FIG. 6, but the locking portion 74 is formed in the support hole 32e. It can abut against the restricting portion 32g and prohibit any further movement of the retracting member 70 in the insertion direction. As a result, the pressing portion 53 can maintain the pressing state of the actuator 17a1 of the first switch member 17a and prevent the switch state of the first switch member 17a 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 state and the first switch member 17a is switched to the ON state, the control unit starts the drive motor M and causes the cam member 12 to counterclockwise. Rotate around.

  When the cam member 12 is rotated counterclockwise, the slide pin 93 provided on the moving gear 90 is moved in the insertion direction along the first slide 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. The slide member 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 member 60 having the second rack portion 62 is inserted. Moved in the direction. When the movable member 60 is moved in the insertion direction, the moving member 50 is pulled in the insertion direction via the biasing member S <b> 2, so that the moving member 50 is also moved in the insertion direction together with the movable member 60. When the moving member 50 is moved in the insertion direction, the cartridge 2 locked by the locking portion 74 of the drawing member 70 mounted on the moving member 50 is automatically set to the recording medium mounting device 10. It is conveyed to the back of the. That is, the cam member 12, the moving gear 90, the moving member 50, the retracting member 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. 8, when the cartridge 2 is loaded, the control pin 15a of the swing member 15 is connected to the outer peripheral end portion 12b1 and the inner peripheral end in the second sliding groove 12b of the cam member 12. It is located in parts other than the part 12b2, and the rocking | swiveling member 15 is set to the neutral position. Therefore, since the second switch member 17b and the third switch member 17c are not operated, the control unit can grasp that the cam member 12 is in a loading state.

(Connector connection operation)
As shown in FIG. 8, when the sliding pin 93 passes the connecting portion 12a4 of the first sliding groove 12a, the sliding pin 93 is moved in the insertion direction by the small arc groove 12a2. As shown in FIG. 9, when the sliding pin 93 reaches the innermost peripheral portion 12a5 of the first sliding groove 12a, the cartridge 2 locked to the retracting member 70 as the sliding pin 93 moves. The connecting portion 42 of the internal connector 40 is inserted into the opening 2a provided on the front surface 2A.

  When the insertion connector 3 of the cartridge 2 and the opening 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 member 60 meshing with the large-diameter pinion gear 91 of the moving gear 90 moves in the insertion direction, the movement of the moving member 50 provided with the retracting member 70 for locking the cartridge 2 is restricted. The insertion connector 3 and the internal connector 40 are fitted in an incomplete state. However, since the movable member 60 is moved to the mounting completion position, the urging member S2 provided between the movable member 60 and the movable member 50 is extended with the movement of the movable member 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 insertion connector 3 and the internal connector 40, the moving member 50 is moved to the mounting completion position by the pulling force. The insert connector 3 and the internal connector 40 can be completely fitted.

  When the insertion connector 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 insertion connector 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.

  As shown in FIG. 9, when the mounting (complete fitting) between the plug-in connector 3 and the internal connector 40 is completed, the control pin 15 a of the swinging member 15 is inserted into the second sliding groove 12 b of the cam member 12. In order to enter the inner peripheral end 12b2, the swing member 15 is swung clockwise in FIG. At this time, since the pressing portion 15b of the swinging member 15 presses the actuator 17b1 of the second switch member 17b, the control portion can grasp that the cam member 12 has reached the state where the connector is completely attached. it can.

  In the initial stage of the loading operation, the sliding pin 93 of the moving gear 90 is moved in the insertion direction by the large arc groove 12a1 of the first sliding groove 12a. As shown in FIG. When the pin 93 passes the connecting portion 12a4 of the first sliding groove 12a, it is now moved in the insertion direction by the small arc groove 12a2.

  Here, since the large arc groove 12a1 is formed with a larger curvature than the small arc groove 12a2, the sliding pin 93 is widened as shown in FIG. The moving distance L1 from the position a1 of the part 12a3 to the position a2 of the connecting part 12a4 shown in FIG. 8 is moved. At this time, as shown in FIG. 8, the moving amount of the locking portion 74 of the retracting member 70, that is, the moving distance of the cartridge 2 in the inserting direction is L0.

  The relationship between the moving distance L0 of the cartridge 2 and the moving distance L1 of the sliding pin 93 is L0 ≦ 2 · L1. That is, in the recording medium mounting apparatus 10, when the large arc groove 12a1 is used, the movement of the cartridge 2 is less than about half the moving distance L1 of the sliding pin 93 (that is, the sliding member 80 on which the moving gear 90 is mounted). The distance L1 can be moved.

  On the other hand, in the process from FIG. 8 to FIG. 9, that is, until the sliding pin 93 reaches the position a3 from the connecting portion 12a4 to the innermost peripheral portion 12a5 from the position a2, the sliding pin 93 is in the small arc groove. It is moved by 12a2. Since the small arc groove 12a2 has a small radius of curvature, the sliding pin 93 is moved by the moving distance L2 from the position a2 to the position a3 while the cam member 12 makes a half turn. At this time, as shown in FIG. 9, the moving amount of the locking portion 74 of the retracting member 70, that is, the moving distance of the cartridge 2 in the inserting direction is L3. That is, in the recording medium mounting apparatus 10, when the small arc groove 12a2 is used, the moving distance L2 of the sliding pin 93 (that is, the sliding member 80 on which the moving gear 90 is mounted) and the moving distance L3 of the cartridge 2 are almost equal. The same (L2≈L3).

  Further, as described above, the number of teeth N1 of the large-diameter pinion gear 91 and the number of teeth N2 of the small-diameter pinion gear 92 are in a relationship of N1> N2. Therefore, when the small-diameter pinion gear 92 rotates the first rack portion 21a by, for example, the number of teeth n, the second rack portion 62 that meshes with the large-diameter pinion gear 91 has the number of teeth (N1 / N2) · n (> n). ) Can be moved as much as possible. That is, the amount of movement in the Y direction of the movable member 60 having the second rack portion 62 and the movable member 50 connected to the movable member 60 via the biasing member S2 is determined as the movable gear 90, that is, the movable gear 90. It is possible to increase the amount of movement in the Y direction of the slide member 80 on which the

  That is, in the recording medium mounting apparatus 10 of the present invention, it is possible to move the cartridge 2 by a moving distance that is at least twice as long as the moving distance of the slide member 80. Therefore, since the moving distance of the slide member 80 in the Y direction can be reduced, the recording medium mounting apparatus 10 can be reduced in size.

  If the rotation speed of the cam member 12 is constant, the cartridge 2 moves by the moving distance L0 while the cam member 12 first makes a half turn (while the sliding pin 93 moves in the large arc groove 12a1). Then, during the remaining 1/2 turn (while the sliding pin 93 moves in the small arc groove 12a2), it is moved by the moving distance L3. That is, most of the movement of the cartridge 2 is performed by the large arc groove 12a1, and the large arc groove 12a1 functions as a moving feed portion that moves the cartridge 2 in the insertion direction.

  Further, since the relationship between the movement distance L0 and the movement distance L3 is L0> L3, the large arc groove 12a1 can convey the cartridge 2 at a higher speed than the small arc groove 12a2. Therefore, when the cartridge 2 is inserted into the insertion portion 10 </ b> A, the cartridge 2 can be quickly drawn into the recording medium mounting apparatus 10. For this reason, even if the outer diameter of the recording medium 1 is long in the Y direction as in the case of the large-sized (2.5 inch type) hard disk, the time required to pull the recording medium 1 into the recording medium mounting apparatus 10 is reduced. Can be shortened.

  When the insertion connector 3 of the cartridge 2 is mounted on the internal connector 40 on the recording medium mounting apparatus 10 side, the sliding pin 93 reaches the small circular groove 12a2 provided on the inner peripheral side of the cam member 12. Therefore, the sliding pin 93 is driven with a larger torque than that of the large circular groove 12a1 on the outer peripheral side. Therefore, since a large pulling force is generated in the pulling member 70, the plug-in connector 3 and the internal connector 40 can be fitted and connected with a stronger force. That is, the small circular groove 12a2 of the cam member 12 functions as a connecting portion for mounting the plug-in connector 3 and the internal connector 40 with a stronger force.

  Moreover, when the sliding pin 93 is moving in the small arc groove 12a2, the biasing force of the biasing member S2 as described above exceeds the insertion load between the plug-in connector 3 and the internal connector 40, and the The plug-in connector 3 is inserted into the opening 43 of the internal connector 40.

  Therefore, in the recording medium mounting apparatus 10 of the present invention, in addition to the large pulling force by the pulling member 70, the pulling force of the biasing member S2 acts as an auxiliary, and the plug connector 3 is connected to the inside with a larger mounting force. Since the connector 40 can be completely fitted, the insertion connector 3 and the internal connector 40 can be securely attached.

  Further, since the large arc groove 12a1 for moving the cartridge 2 and the small arc groove 12a2 for connecting the connectors are formed by a continuous first sliding groove 12a, the connectors are separated from each other by a moving operation for moving the cartridge 2. It is possible to quickly shift to a connection operation for connection.

  When the mounting operation of the cartridge 2 in the recording medium mounting apparatus 10 is completed, the entire cartridge 2 is the recording medium mounting apparatus regardless of whether the recording medium 1 is a small recording medium 1 or a large recording medium 1. 10 can be completely retracted. Therefore, an external force does not act on a part of the cartridge 2 during operation, and the possibility of causing a data error or data destruction can be eliminated.

  In the above embodiment, a removable hard disk has been described as an embodiment of a recording medium having a connector. However, the present invention is not limited to this, and for example, an IC memory in the cartridge 2 instead of a magnetic disk. May be a recording medium containing the.

  In the above embodiment, the movable member 60 is configured separately from the moving member 70. However, the present invention is not limited to this, and the second rack portion 62 is opened to the moving member 50. It is also possible to adopt a configuration in which the edge of the hole 51 is formed integrally. However, the separate configuration as described above is advantageous in that the insertion connector 3 and the internal connector 40 can be completely fitted using the pulling force of the biasing member S2.

  Furthermore, in the above embodiment, the moving gear 90 is shown as a two-stage gear composed of two types of pinion gears having different numbers of teeth. However, the present invention is not limited to this, and the moving gear 90 composed of one pinion gear is not limited to this. It is also possible to adopt a configuration in which the first rack portion 21a and the second rack portion 62 are engaged with each other. However, when the two-stage gear is used as described above, the moving amount of the moving member 50 and the moving member 60 is increased with respect to the moving amount of the slide member 80 on which the moving gear 90 is mounted using the gear ratio. This is advantageous in that it can.
