Description

  The present invention relates to a recording medium driving apparatus, and more particularly to a recording medium driving apparatus that automatically conveys a recording medium by a driving force of a motor and connects it to a connector.

  Conventionally, a recording medium on which various data has been recorded is manually inserted and held in a holder, and this holder is automatically transported into the housing by a transport mechanism. A recording medium driving device is known in which a movable connector and a fixed connector disposed in a housing are connected (see, for example, Patent Document 1). Here, the movable connector consists of a plurality of clip-shaped female terminals arranged at a predetermined pitch, and the fixed connector consists of a plurality of pin-shaped male terminals arranged at the same pitch as the female terminals. The transport mechanism includes a reduction gear train that rotates using a motor as a drive source, and a rack that meshes with a final gear of the reduction gear train, and this rack is fixed to a side surface of the holder.

In the recording medium driving apparatus schematically configured as described above, when the motor rotates in one direction after the recording medium is inserted and held in the holder, the holder is linearly moved toward the inside of the casing by the transport mechanism using the motor as a driving source. Move on. When the holder moves to the mounting position in the housing, the fixed-side connector disposed in the housing is inserted into the movable connector of the recording medium held by the holder, and the recording medium is mounted in the apparatus. Connector is connected. In addition, when the motor rotates in the opposite direction to the above with the recording medium mounted, the holder moves linearly from the mounting position toward the front of the housing, and accordingly, the movable connector comes out of the fixed connector. After being disconnected, the recording medium is automatically conveyed to the initial position where it can be ejected.
Japanese Patent Laying-Open No. 2004-348812 (page 5-7, FIG. 4)

  In the conventional recording medium driving device described above, the recording medium held by the holder is automatically conveyed by a conveyance mechanism using a motor as a driving source, and the movable side connector of the recording medium is moved relative to the fixed side connector using the conveyance force. The standard value of the connector insertion / extraction force that satisfies this operation is quite high (for example, 2 kg · f). Therefore, if the motor torque is insufficient, the movable side connector and the fixed side connector are securely connected. Cannot connect / disconnect. For this reason, it is necessary to increase the torque of the motor. However, when a high torque motor is used, it is difficult to increase the conveyance speed of the recording medium or the mechanical structure including the conveyance mechanism has high mechanical strength. Various problems occur, for example, strength is required.

  The present invention has been made in view of the actual situation of the prior art, and an object of the present invention is to provide a recording medium driving device capable of realizing a reliable connector connection of a recording medium even when a low torque motor is used. It is in.

  In the present invention, the driving force of the motor is switched during the conveyance of the holder so that the first and second conveyance mechanisms are selectively operated, and the holder is conveyed by the first conveyance mechanism until just before the connector of the recording medium is connected. In addition, while the recording medium connector is connected, the second transport mechanism transports the holder with a transport force larger than that of the first transport mechanism.

  The recording medium driving device of the present invention switches the conveying force of a holder operated by using a motor as a driving source in the middle of conveyance, and is mounted with respect to the conveying force when conveying the recording medium between the media insertion position and the mounting position. Since the transport force when inserting the movable connector of the recording medium into the fixed connector in the housing is increased at the position, the transport force transmission path from the motor to the holder can be used even if a low torque motor is used. In addition, the recording medium can be reliably connected to the connector without using a complicated speed reduction mechanism.

According to the present invention, a recording medium having a movable connector on the distal end side in the insertion direction is inserted and held in a holder at a medium insertion position, and this holder is automatically conveyed from the medium insertion position to a mounting position in a housing by a driving force of a motor. In the recording medium driving device in which the movable connector of the recording medium is connected to the fixed connector disposed in the housing at the mounting position, the holder is connected to the medium insertion position and the mounting position. A first transport mechanism that transports between the movable connector and the fixed connector on the near side before the connection is made, and transports the holder between the switch position and the mounting position. a second conveying mechanism, and a switching means for selectively transmitting the driving force of the motor to the first and second transport mechanism, the first transport mechanism rotatable In addition to a rotary arm, the second transfer mechanism is a slider that can move in a direction perpendicular to the transfer direction of the holder, and the switching means is interposed between the rotary arm and the slider. and towards the second conveying mechanism to the first transport mechanism configured to transport the holder with a large conveyance force.

In the recording medium driving device configured as described above, the conveyance force of the holder operated by using the motor as a drive source is switched during conveyance, and the conveyance force when conveying the recording medium between the media insertion position and the mounting position is short. Since the transport force when inserting the movable connector of the recording medium into the fixed connector in the housing is increased at the mounting position, the transport from the motor to the holder is possible even when a low torque motor is used. Even if a complicated speed reduction mechanism is not used in the force transmission path, the recording medium can be reliably connected to the connector. In addition, the first transport mechanism is composed of a pivotable arm, and the second transport mechanism is composed of a slider that is movable in a direction perpendicular to the transport direction of the holder. Since the switching means is interposed between the slider and the slider, the lever transport ratio from the center of rotation of the rotating arm to the holder and the switching means is used to increase the transport stroke of the holder with a small amount of movement of the switching means. be able to.

In the above configuration, the slider has an inclined hole extending in a direction inclined with respect to the conveyance direction of the holder, and a pin provided on the holder slides in the inclined hole, whereby the movement of the slider is performed. It is preferable to convert the transfer driving force of the holder.

  Further, in the above configuration, the switching means includes a drive member that is movable in the carrying direction of the holder and connected to the rotating arm, and a rotatable relay member connected to the slider, Due to the movement of the driving member in the first range, the rotating arm conveys the holder between the media insertion position and the switching position, and the second range following the first range of the driving member. When the holder is transported by the relay member and the slider between the switching position and the mounting position by the movement of the motor, the driving force of the motor is transferred to the first transport mechanism and the second transport mechanism. It can be switched reliably. In this case, it is preferable that a rack extending in the moving direction is formed on the drive member, and the rotation of the motor is transmitted to the rack via a reduction gear train.

  In the above configuration, the driving member is provided with a long hole extending in the moving direction, and the relay pin has a first pin inserted into the long hole and a second pin connected to the slider. When the distance from the rotation center of the relay member to the first and second pins is set to be substantially the same, the insertion / extraction force of the movable connector with respect to the fixed connector can be increased. .

  In the above configuration, the driving member is provided with an engagement hole having a locking portion and a relief portion, and the rotation arm is provided with a drive pin inserted into the engagement hole, When the drive pin and the locking portion abut, the movement of the first range of the drive member is converted into the rotation of the rotation arm, and the drive pin moves in the escape portion, thereby It is preferable that the driving member is configured such that the movement of the second range is not absorbed and converted into the rotation of the rotating arm.

  Further, in the above configuration, the switching means includes a rotatable cam plate having first and second cam grooves, and a first drive pin provided on the rotating arm is engaged with the first cam groove. In addition, when the second drive pin provided on the slider is engaged with the second cam groove, the configuration of the switching means can be simplified. In this case, it is preferable that a gear portion is formed on the outer peripheral surface of the cam plate, and the rotation of the motor is transmitted to the gear portion via a reduction gear train.

  In the above configuration, the rotating arm includes a first rotating arm connected to the switching unit and a second rotating arm connected to the holder. When the movable arm is rotatably connected on the same axis, and the first and second rotating arms are elastically biased so as to rotate together, the holder is moved to the second transport mechanism. Since the movement of the holder is absorbed by the rotation of the second rotation arm with respect to the first rotation arm when the connector is transported and the connector is inserted / removed, the first rotation connected to the switching means is performed. This is preferable because an excessive force can be prevented from acting on the moving arm.

  As shown in FIGS. 1 to 5, the recording medium driving device according to the present embodiment includes a box-shaped housing 1 installed at a predetermined position (for example, in a console) in a vehicle compartment, and a front opening of the housing 1. And a front panel 2 attached to the end, and a recording medium 3 can be inserted into / extracted from the housing 1 through an insertion port 2a opened in the front panel 2. As shown in FIG. 6, the recording medium 3 is a recording medium in which a hard disk (not shown) as a recording medium is housed in a synthetic resin cartridge 4, and a movable connector 5 is provided on the insertion side end surface of the cartridge 4. ing. Further, a guide groove 4a extending in the insertion / discharge direction and a concave portion 4b for clamping are formed on the left and right side surfaces of the cartridge 4.

  A holder 6 having an open front is disposed inside the housing 1, and the recording medium 3 inserted into the housing 1 from the insertion port 2 a is held by the holder 6. Three pins 6 a, 6 b, 6 c are implanted on the upper surface of the holder 6, and these pins 6 a, 6 b, 6 c are guided in linear guide holes 1 a formed on the upper surface of the housing 1. As a result, the holder 6 can move in the front-rear direction (X1-X2 direction) of the housing 1 between the media insertion position shown in FIG. 3 and the mounting position shown in FIG. A clamper 7 for holding the recording medium 3 is rotatably supported on the left and right inner portions of the holder 6, and both the clampers 7 are rotated toward the inside of the holder 6 by the elastic force of the torsion coil spring 8. It is energized. Note that escape holes 1b are formed on the left and right side surfaces of the housing 1, and both clampers 7 are allowed to rotate outwardly by the escape holes 1b only when the holder 6 is at the media insertion position shown in FIG. It has come to be.

  A low-torque motor 9 is installed on the left side of the housing 1 in the figure, and a worm gear 10 attached to the rotating shaft of the motor 9 is a first stage gear of a simple reduction gear train 11 composed of two reduction gears. Meshed. The final gear of the reduction gear train 11 is meshed with a rack 13 provided on the left side of the drive member 12 in the figure, and the rotation of the motor 9 is converted into a linear motion of the rack 13 via the worm gear 10 and the reduction gear train 11. As a result, the drive member 12 reciprocates in the front-rear direction (X1-X2 direction) of the housing 1. The drive member 12 is formed with a through hole 12 a, a long hole 12 b, and an engagement hole 14, and the through hole 12 a and the long hole 12 b extend linearly in the front-rear direction of the housing 1. The engagement hole 14 includes a locking portion 14a and a relief portion 14b that are continuous in an inverted L shape. The locking portion 14a extends in the left-right direction (Y1-Y2 direction) of the housing 1, and the relief portion 14b is The casing 1 extends in the front-rear direction (X1-X2 direction).

  On the upper surface side of the housing 1, a rotating arm 15 that is a first transport mechanism and a slider 16 that is a second transport mechanism are arranged. The rotating arm 15 is centered on a rotating shaft 17. The slider 16 is supported by the body 1 so as to be rotatable in the direction of arrows AB, and the slider 16 can move in the left-right direction (Y1-Y2 direction) of the housing 1 along the guide pins 1c protruding from the upper surface of the housing 1. It is supported by. As will be described later, the driving force of the motor 9 is selectively transmitted to the rotating arm 15 and the slider 16, and the rotating arm 15 moves the holder 6 to the media insertion position shown in FIG. The slider 16 conveys the holder 6 between the switching position shown in FIG. 4 and the mounting position shown in FIG.

  The rotating arm 15 includes a first rotating arm 18 and a second rotating arm 19 that are coaxially connected via a rotating shaft 17, and the rotating shaft 17 is formed through the drive member 12. It is inserted into the hole 12a. A drive pin 18 a is implanted in the first rotating arm 18, and this drive pin 18 a is inserted into the engagement hole 14 of the drive member 12. As a result, the first rotating arm 18 is rotated with the movement of the driving member 12 only when the driving pin 18 a is in the engaging portion 14 a of the engaging hole 14, and the driving pin 18 a is moved to the engaging hole 14. When moving into the escape portion 14b, the first rotating arm 18 does not rotate even if the driving member 12 moves. A long hole 19 a is formed at the tip of the second rotating arm 19. Of the three pins 6 a, 6 b and 6 c planted in the holder 6, the central pin 6 a is the long hole. 19a is inserted. The distance from the rotation shaft 17 to the pin 6a is set to be sufficiently longer than the distance between the rotation shaft 17 and the drive pin 18a, and the driving force is small for conveying the holder 6, but the first The holder 6 can be transported at a high speed with a large movement amount even with a small rotation angle of the rotating arm 18. Further, the first turning arm 18 is formed with a pair of restriction walls 18b, 18c for restricting the turning of the second turning arm 19, and the first and second turning arms 18, A tension spring 20 is stretched on the end of the arm 19, and the tension spring 20 causes the second rotating arm 19 to be elastically applied in a direction in which it presses against the restriction wall 18 b on the front side of the first rotating arm 18. It is energized. Thus, when the first rotation arm 18 rotates as the drive member 12 moves forward and backward, the first and second rotation arms 18 and 19 rotate integrally around the rotation shaft 17. However, when an external force in the direction of the arrow X2 acts on the second rotating arm 19 from the holder 6 with the first rotating arm 18 stopped, the second rotating arm resists the tension of the tension spring 20. Only 19 is rotated from the restriction wall 18b on the near side of the first rotation arm 18 by a minute angle toward the restriction wall 18c on the back side.

  A relay member 21 having a triangular shape in plan view is rotatably supported in the left inner portion of the housing 1 in the figure, and the driving force of the motor 9 is applied to the rotating arm 15 and the slider by the relay member 21 and the driving member 12. Switching means for selectively transmitting to 16 is configured. First and second pins 21a, 21b and a rotation shaft 21c are implanted at each top of the relay member 21, and the relay member 21 is rotatable about the rotation shaft 21c. The first pin 21a of the relay member 21 is inserted into the long hole 12b of the driving member 12, and when the first pin 21a moves in the long hole 12b as the driving member 12 moves back and forth, the driving member 12 Is not transmitted to the relay member 21, but when the first pin 21a comes into contact with the rear end of the long hole 12b, the relay member 21 rotates about the rotation shaft 21c as the drive member 12 moves. It has become. On the other hand, the second pin 21b of the relay member 21 is inserted into a connecting hole 16a formed in the slider 16, and the slider 16 moves in the left-right direction (Y1-Y2 direction) of the housing 1 as the relay member 21 rotates. To move to. Here, the magnitude of the driving force transmitted from the relay member 21 to the slider 16 can be arbitrarily set according to the distance from the rotation shaft 21c to the first and second pins 21a and 21b. In this embodiment, Since the distances from the rotation shaft 21c to the first and second pins 21a and 21b are set to be substantially equal, even if the low-torque motor 9 is used as a drive source, the rotational drive force of the relay member 21 Thus, the slider 16 moves with a large driving force. The slider 16 is formed with a pair of inclined holes 16c extending obliquely rearward from the front end surface, and these inclined holes 16c overlap the left and right guide holes 1a formed in the housing 1 in a planar manner. . Therefore, when the holder 6 is conveyed to a position where it overlaps with the slider 16, the two left and right pins 6b and 6c of the holder 6 enter the inclined hole 16c while engaging with the guide hole 1a. The inclined hole 16c extends rearward at an inclination angle of 45 ° with respect to the movement direction (X1-X2 direction) of the holder 6.

  Further, first and second detection switches 22 and 23 are installed inside the housing 1, and the motor 9 is started / stopped based on signals from the first and second detection switches 22 and 23. It is supposed to be. The first detection switch 22 is turned on / off by the second rotating arm 19, and the second detection switch 23 is turned on / off by the front end portion of the rack 13 provided on the drive member 12. Further, a fixed-side connector 24 is disposed in the innermost part in the housing 1, and when the recording medium 3 held by the holder 6 is transported to the mounting position shown in FIG. The side connector 5 is connected to the fixed side connector 24. Although the detailed structure is not shown, the movable connector 5 includes a plurality of clip-shaped female terminals arranged at a predetermined pitch, and the fixed-side connector 24 includes a plurality of pin-shaped male terminals as female terminals. It consists of the ones arranged at the same pitch.

  Next, the operation of the recording medium driving device configured as described above will be described.

  FIG. 1 shows a standby state at the time of ejection when the recording medium 3 is not inserted into the housing 1, and in this case, the holder 6 is at the forward position (media insertion position) closest to the housing 1. Further, the drive member 12 is positioned closer to the rear of the housing 1, and the drive pin 18 a of the rotating arm 15 is in the locking portion 14 a of the engagement hole 14. Further, the first pin 21a of the relay member 21 is on the front end side of the long hole 12b of the drive member 12, and the slider 16 is at the end position in the Y1 direction.

  In such a standby state, as shown in FIG. 2, when the user starts to insert the recording medium 3 into the holder 6 in the housing 1 from the insertion opening 2a, both corners on the front end side in the insertion direction of the recording medium 3 are clampers. 7, both clampers 7 are rotated outward by the insertion force of the recording medium 3. When the leading end of the recording medium 3 is inserted to the innermost part of the holder 6, both clampers 7 rotate inward by the elastic force of the torsion coil spring 8 and enter the recess 4b, so that the medium insertion position shown in FIG. As shown, the recording medium 3 is held by a holder 6 by both clampers 7. When the user further pushes the recording medium 3 into the housing 1 from this state, the holder 6 moves slightly in the X2 direction and presses the second rotating arm 19 in the counterclockwise direction (arrow B direction). As described above, only the second turning arm 19 rotates with respect to the first turning arm 18 by a slight angle from the front-side restriction wall 18b toward the back-side restriction wall 18c, and is detected accordingly. The switch 22 is turned on to start the motor 9.

  When the motor 9 starts to rotate in one direction in this way, the rotation of the motor 9 is converted into a linear motion of the rack 13 via the worm gear 10 and the reduction gear train 11, and as shown in FIG. The drive member 12 located near the rear of 1 moves to the near side (X1 direction), and accordingly, the rotation arm 15 rotates about the rotation shaft 17 in the arrow B direction. That is, when the driving member 12 moves in the X1 direction from the media insertion position in FIG. 3 by a predetermined distance (first range), the driving pin 18a of the first rotating arm 18 is moved to X1 by the locking portion 14a of the engaging hole 14. The first and second rotating arms 18 and 19 rotate integrally around the rotating shaft 17 in the direction of the arrow B and are connected to the second rotating arm 19. 6 is conveyed in the X2 direction from the media insertion position shown in FIG. 3 to the switching position shown in FIG. In this case, since the driving force required for the rotating arm 15 may be a small force that can transport the holder 6 holding the recording medium 3 to the switching position, the first and second rotating arms 18, 19 A low torque motor 9 can be used as a drive source, and the conveyance speed of the holder 6 can be increased.

  At the switching position, the holder 6 is transported to a position where it overlaps the slider 16, so that the two left and right pins 6 b and 6 c of the holder 6 enter the inclined hole 16 c of the slider 16 and the movable connector 5 of the recording medium 3. Faces the fixed connector 24 disposed in the innermost part of the housing 1 with a slight gap. During this time, the first pin 21a of the relay member 21 relatively moves from the front end to the rear end in the elongated hole 12b of the drive member 12, so that the drive force of the drive member 12 using the motor 9 as a drive source is relayed. The slider 16 is not transmitted to the member 21 and does not move while being held at the end position in the Y1 direction. In addition, the rotation shaft 17 of the rotation arm 15 relatively moves in the through hole 12a of the drive member 12, and the drive pin 18a is rotated by the first rotation arm 18 in the direction B in the engagement hole 14. Transition from the locking portion 14a to the escape portion 14b.

  When the driving member 12 further moves in the second range from the switching position shown in FIG. 4 toward the front side (X1 direction) of the housing 1 using the motor 9 as a driving source, the driving pin 18a is a relief portion of the engaging hole 14. 14b is relatively moved, the driving force of the driving member 12 using the motor 9 as a driving source is not transmitted to the first rotating arm 18, but instead the first pin 21a is located behind the long hole 12b. Since the relay member 21 rotates in the counterclockwise direction in FIG. 4 around the rotation shaft 21c, the slider 16 has a large driving force from the end position in the Y1 direction to the Y2 direction. Start moving. When the slider 16 starts to move in the Y2 direction in this way, both pins 6b and 6c of the holder 6 are pressed against the oblique side of the inclined hole 16c of the slider 16 and shift to the back side of the guide hole 1a. Is further conveyed in the X2 direction to reach the mounting position shown in FIG. 5, and at this mounting position, the second detection switch 23 is turned on at the front end of the rack 13 and the motor 9 stops. While the holder 6 is conveyed from the switching position to the mounting position, the fixed connector 24 is inserted into the movable connector 5 of the recording medium 3 held by the holder 6, and the recording medium 3 is mounted in the apparatus. The connector is connected in the connected state.

  That is, when the holder 6 is transported from the media insertion position shown in FIG. 3 to the switching position shown in FIG. 4, the driving force of the driving member 12 using the motor 9 as a driving source is switched to the slider 16 via the relay member 21. The holder 6 is conveyed to the mounting position shown in FIG. At this time, since the distance from the rotation shaft 21c of the relay member 21 to the first and second pins 21a and 21b is set to be substantially equal, the sliding amount of the slider 16 with respect to the rotation amount of the relay member 21 is so large. In addition, the conveyance speed of the holder 6 is also slower than the conveyance speed by the rotating arm 15, but the slider 16 moves with a large driving force relative to the rotational driving force of the relay member 21. Therefore, the holder 6 can be used in a short section from the switching position to the mounting position without using the low-torque motor 9 and providing a large speed reduction mechanism in the conveying force transmission path between the motor 9 and the holder 6. Is transferred by the slider 16 with a large driving force, and a high insertion / extraction force (for example, 2 kg · f) required between the movable side connector 5 and the fixed side connector 24 of the recording medium 3 held by the holder 6. ) Can be satisfied. While the holder 6 is transported to the mounting position as the slider 16 moves as described above, the first rotating arm 18 of the rotating arm 15 does not rotate, but the second rotating arm 19 includes A turning force in the direction of arrow B acts from the holder 6. Also in this case, as in the case of insertion of the recording medium 3, only the second turning arm 19 with respect to the stopped first turning arm 18 is moved from the front-side restriction wall 18b to the rear-side restriction wall 18c. Therefore, the external force applied to the first and second rotating arms 18 and 19 can be absorbed.

  Further, when ejecting the recording medium 3 mounted in the apparatus, when an unillustrated eject button is operated, the motor 9 starts to rotate in the reverse direction and the reverse operation is performed, and the holder 6 is mounted. Since the user moves in the X1 direction from the position to the medium insertion position shown in FIG. 3 through the switching position, the user can eject the recording medium 3 to the outside of the housing 1. In this case, while the holder 6 is transported by the slider 16 from the mounting position to the switching position, the movable connector 5 of the recording medium 3 comes out of the fixed connector 24 and is disconnected. 15 is transported from the switching position to the media insertion position.

  FIG. 7 is a main part plan view showing a medium holding state of the recording medium driving apparatus according to the second embodiment of the present invention, FIG. 8 is a main part plan view showing a medium conveying state of the recording medium driving apparatus, and FIG. FIG. 6 is a plan view of a main part showing a media conveyance completion state of the recording medium driving device, where parts corresponding to those in FIGS.

  The recording medium driving apparatus according to this embodiment is different from the first embodiment described above in that the cam plate 25 is used as a switching means for selectively transmitting the driving force of the motor 9 to the first and second transport mechanisms. The rest of the configuration is basically the same. The cam plate 25 is rotatably supported by the housing 1, and a gear portion 25 a engraved on the outer peripheral surface thereof meshes with the final gear of the reduction gear train 11. It can be rotated in both forward and reverse directions as a drive source.

  The cam plate 25 is provided with a first cam groove 26 and a second cam groove 27, and the first cam groove 26 is implanted in the first rotating arm 18 which is a first transport mechanism. The drive pin 18a is engaged, and the second cam groove 27 is engaged with the drive pin 16d implanted in the slider 16 as the second transport mechanism. The first cam groove 26 indicated by a solid line is composed of a non-arc portion 26a in which the distance from the rotation shaft 25b of the cam plate 25 sequentially changes and an arc portion 26b in which the distance from the rotation shaft 25b of the cam plate 25 is constant. The second cam groove 27 indicated by a two-dot chain line is formed on the back surface of the cam plate 25, and the non-arc portion 27a in which the distance from the rotation shaft 25b of the cam plate 25 sequentially changes, and the rotation shaft 25b of the cam plate 25. And a circular arc portion 27b having a constant distance from As in the first embodiment, the distance from the rotation shaft 17 to the pin 6a of the holder 6 is set sufficiently longer than the distance between the rotation shaft 17 of the rotation arm 15 and the drive pin 18a. The driving force (conveying force of the holder 6) when the driving pin 18a traces the inside of the non-circular arc portion 26a of the first cam groove 26 to rotate the first rotating arm 18 is small. The holder 6 can be moved at a high speed with a small rotation angle of the first rotating arm 18. On the other hand, the drive pin 16d of the slider 16 traces within the non-circular portion 27a of the second cam groove 27 and is directly driven by the non-circular portion 27a. Therefore, the slider 16 slides with a large driving force at a low speed. Driven.

  In the recording medium driving apparatus configured as described above, as shown in FIG. 7, the drive pin 18 a on the first rotating arm 18 side is the first at the medium insertion position where the recording medium is inserted and held in the holder 6. The drive pin 16 d on the slider 16 side is located at the end position of the arc portion 27 b of the second cam groove 27. From this state, when the cam plate 25 rotates counterclockwise in the figure using the motor as a drive source, the drive pin 18a on the first rotating arm 18 side arcs in the first cam groove 26 from the end position of the non-arc portion 26a. In order to trace toward the part 26b, as shown in FIG. 8, the rotating arm 15 (first and second rotating arms 18, 19) is rotated in the direction of arrow B to convey the holder 6 to the switching position. To do. During this time, the drive pin 16 d on the slider 16 side traces within the arc portion 27 b of the second cam groove 27, so that the rotational driving force of the cam plate 25 is not transmitted to the slider 16.

  When the cam plate 25 further rotates counterclockwise from the switching position shown in FIG. 8, the drive pin 18a on the first rotating arm 18 side traces within the arc portion 26b of the first cam groove 26. 9 is not transmitted to the first rotating arm 18, and instead the driving pin 16d on the slider 16 side traces the inside of the non-arc portion 27a of the second cam groove 27, which is shown in FIG. As described above, the slider 16 moves in the Y2 direction from the end position in the Y1 direction to transport the holder 6 to the mounting position. Similar to the first embodiment described above, when the slider 16 starts to move in the Y2 direction in this way, both pins 6b and 6c of the holder 6 are pressed against the oblique sides of the inclined hole 16c of the slider 16 to the back side of the guide hole 1a. Therefore, the fixed connector 24 is inserted into the movable connector 5 of the recording medium 3 held by the holder 6, and the recording medium 3 is connected to the connector in a state of being mounted in the apparatus.

  That is, in the second embodiment, the first and second cam grooves 26 and 27 are provided in the cam plate 25 as the switching means, and the holder 6 moves from the media insertion position shown in FIG. 7 to the switching position shown in FIG. While being conveyed, the drive pin 18a is engaged with the arc portion 26b of the first cam groove 26 to rotate the first rotating arm 18, and the holder 6 is moved from the switching position shown in FIG. 8 to FIG. Since the drive pin 16d is engaged with the non-circular arc portion 27a of the second cam groove 27 and the slider 16 is moved while being transported to the mounting position shown in FIG. Can be selectively transmitted to the first transport mechanism (rotating arm 15) and the second transport mechanism (slider 16), and the structure of the recording medium driving device can be simplified accordingly. Further, since the driving force of the holder 6 by the slider 16 can be set sufficiently larger than the driving force of the holder 6 by the rotating arm 15, even if a low torque motor is used as a driving source, the movable side of the recording medium 3 can be used. A high insertion / extraction force (for example, 2 kg · f) required between the connector 5 and the fixed connector 24 can be satisfied.

  The switching position of the holder 6 in each of the above embodiments is set to a position immediately before the movable connector 5 of the recording medium is inserted into the fixed connector 24 in the housing 1. The moving amount of the holder 6 by the moving arm 15) is maximized so that the recording medium 3 can be conveyed as fast as possible. However, when high-speed conveyance of the recording medium 3 is not required, the switching position of the holder 6 may be set closer to the insertion port 2a.

  In each of the above embodiments, an example in which the cartridge 4 containing a hard disk, which is a magnetic disk, is used as the recording medium 3 has been described. However, the present invention is not limited to this. It may be a cartridge type recording medium.
