The housing 3 has a flat shape and includes two large surface portions facing each other and four small surface portions connected to an edge portion of the large surface portion. One of the small surface portions is provided with a slot (insertion opening) 4 parallel to the edge of the large surface portion (hereinafter, the small surface portion provided with the slot 4 is referred to as a front surface portion). The slot 4 is substantially parallel to the long edge portion of the front surface portion of the housing 3. The length of the slot 4 is slightly longer than the diameter of the disk 2, and the dimension (width dimension) in the direction perpendicular to the longitudinal direction is slightly longer than the thickness of the disk 2. Holding members 4a and 4b for holding the disk 2 are provided on both long edges of the slot 4, respectively, and the holding members 4a and 4b face each other. The holding members 4a and 4b are made of a material (for example, a cloth material such as a felt) having a degree of flexibility that does not damage the recording surface of the disk 2 at the time of contact. The distance between the holding members 4 a and 4 b is shorter than the thickness of the disk 2.

  Both side surfaces of the disk 2 are a recording surface for recording information and a non-recording surface for not recording information. The disk 2 is inserted into the slot 4 or carried out of the slot 4 so that the direction perpendicular to the side surface is perpendicular to the longitudinal direction of the slot 4. The disk 2 is inserted into and removed from the slot 4 so that the recording surface faces the holding member 4b. The holding members 4a and 4b hold the disc 2 carried out from the recording / reproducing unit 5 at a take-out position described later. The holding member 4b cleans the recording surface of the disc 2 to be inserted / removed each time the disc 2 is inserted / removed.

  Inside the housing 3, there are provided a recording / reproducing unit 5 (recording / reproducing unit) for recording and reproducing information with respect to the disc 2 and a conveying mechanism 6 (conveying unit) for conveying the disc 2. The transport mechanism 6 is disposed between the slot 4 and the recording / reproducing unit 5. The transport mechanism 6 transports the disc 2 between the carry-in start position and the recording / reproducing unit 5 or between the take-out position and the recording / reproducing unit 5.

  The carry-in start position is a position of the disk 2 where the carry-in is started in a state where a part of the disk 2 is inserted into the slot 4. The take-out position is the position of the disk 2 that has stopped in a state where a part of the disk 2 protrudes from the slot 4. Hereinafter, the direction in which the disk 2 is conveyed from the loading start position to the recording / reproducing unit 5 is referred to as the loading direction, and the opposite direction is referred to as the unloading direction.

  FIG. 2 is a plan view showing an outline of the recording / reproducing unit 5 and the transport mechanism 6 of the disk device 1. FIG. 3 is a plan view showing an outline of the recording / reproducing unit 5 and the front arms 62L and 62R.

The shafts 62LA and 62RA are perpendicular to the front arms 62L and 62R, and the front arms 62L and 62R can rotate in the carry-in direction and the carry-out direction about the shafts 62LA and 62RA. The front arms 62L and 62R are urged toward the slit 4 (unloading direction) by an elastic member (not shown).

  A first fixed roller 62L4 and a second fixed roller 62L5 are sequentially arranged in parallel toward the recording / reproducing unit 5 at the arc-shaped edge portion of the fan-shaped front arm 62L. The first fixed roller 62L4 protrudes from the opening 615L. The second fixed roller 62L5 is located outside the edge portion of the bracket 61 and protrudes in the same direction as the first fixed roller 62L4. The first fixed roller 62L4 and the second fixed roller 62L5 can rotate with the direction perpendicular to the front arm 62L as the axial direction. The first fixed roller 62L4 and the second fixed roller 62L5 are arranged so that the outer peripheral portion of the disk 2 contacts the first fixed roller 62L4 and the second fixed roller 62L5 when the disk 2 is inserted.

  An arcuate guide hole 62L2 is formed in the central portion of the front arm 62L. The guide hole 62L2 corresponds to the guide hole 616 of the bracket 61. A detection lever 642 is inserted through the guide hole 62L2 and the guide hole 616, and the detection lever 642 protrudes from the guide hole 616. The detection lever 642 that has received the pressure moves while being guided by the guide hole 62L2 and the guide hole 616. In addition, the detection lever 642 is urged | biased by the slit 4 side (unloading direction) by the said elastic member.

The first drive roller 62R6 protrudes from the opening 615R. The second drive roller 62R7 is located outside the edge portion of the bracket 61 and protrudes in the same direction as the first drive roller 62R6.

  The first drive roller 62R6 and the second drive roller 62R7 are arranged so that the outer peripheral portion of the disk 2 contacts the first drive roller 62R6 and the second drive roller 62R7 when the disk 2 is inserted. The first drive roller 62R6 and the second drive roller 62R7 have a gear portion (not shown) on their peripheral surfaces.

  Three support shafts (not shown) perpendicular to the front arm 62R are juxtaposed inward at the center of the front arm 62R. The first gear 62R3, the second gear 62R4, and the third gear 62R5 are rotatably supported on the support shaft. The first gear 62R3 meshes with the gear portion of the first drive roller 62R6, and the third gear 62R5 meshes with the gear portion of the second drive roller 62R7. The second gear 62R4 meshes with the first gear 62R3 and the third gear 62R5.

As the roller drive motor 15 is driven, the first gear 62R3 rotates and the second gear 62R4 rotates. The second gear 62R4 rotates the third gear 62R5. The rotation directions of the first gear 62R3 and the third gear 62R5 are the same direction. Therefore, the first drive roller 62R6 and the second drive roller 62R7 rotate in the same direction.
The diameter and the number of teeth of the first gear 62R3, the second gear 62R4, and the third gear 62R5 are set so that the rotation speed per unit time of the first gear 62R3 and the third gear 62R5 is the same. Yes.

FIG. 4 is an explanatory view showing the arrangement of the disk 2 and the front arms 62L and 62R in the middle of loading.
When the disk 2 is inserted into the slot 4 and the outer peripheral portion of the disk 2 is in contact with the first drive roller 62R6 and the second drive roller 62R7, and the roller drive motor 15 rotates forward, the disk 2 has the recording / reproducing unit 5 It is conveyed toward. At this time, as shown in FIG. 4, the front arms 62L and 62R rotate around the shafts 62LA and 62RA toward the recording / reproducing unit 5 side. The detection lever 642 moves while being guided by the guide hole 62L2 and the guide hole 616 by the pressing of the disk 2 and the biasing force of the elastic member.

  On the other hand, when the roller drive motor 15 rotates in the reverse direction with the outer peripheral portion of the disk 2 in contact with the first drive roller 62R6 and the second drive roller 62R7, the disk 2 is unloaded from the recording / reproducing unit 5. At this time, as shown in FIG. 3, the front arms 62L and 62R rotate around the shafts 62LA and 62RA to the opposite side (slot 4 side) from the recording / reproducing unit 5. The detection lever 642 moves while being guided by the guide hole 62L2 and the guide hole 616 by the pressing of the disk 2 and the biasing force of the elastic member.

FIG. 5 is an explanatory diagram showing the arrangement of the disk 2, the first switch 16, the second switch 17, and the third switch 18.
A first switch 16, a second switch 17, and a third switch 18 are provided on the opposite side of the bracket 61 across the front arm 62L. The first switch 1 is arranged at a position close to the slot 4, and the second switch 17 is arranged at a position far from the slot 4. The third switch 18 is disposed between the first switch 16 and the second switch 17. The first switch 16 to the third switch 18 are arranged on the moving path of the detection lever 642. The on / off state of each switch is switched by being pressed by the detection lever 642.

  When the disk 2 is inserted from the slot 4, the disk 2 comes into contact with the first fixed roller 62L4, the second fixed roller 62L5, the first drive roller 62R6, and the second drive roller 62R7 (solid line position in FIG. 5). Further, the disk 2 comes into contact with the detection lever 642. When the disc 2 is further inserted, the detection lever 642 is pressed against the outer peripheral portion of the disc 2. The detection lever 642 presses the first switch 16 to turn it on (the one-dot chain line position in FIG. 5).

  Thereafter, when the disc 2 is carried in slightly in the carrying-in direction from the position of the one-dot chain line in FIG. 5, the detection lever 642 presses the third switch 18 and turns on the third switch 18.

  Further, when the disk 2 continues to be carried and the disk 2 reaches the dotted line position in FIG. 5, the detection lever 642 presses the second switch 17 to turn it on.

  When the recording / reproducing unit 5 starts to carry out the disc 2 clamped by the clamper, the detection lever 642 is pushed by the outer peripheral portion of the disc 2. When the detection lever 642 presses the second switch 17 by pressing the disk 2, the second switch 17 is switched to the off state.

  When the unloading of the disk 2 further proceeds and the detection lever 642 presses the third switch 18, the third switch 18 is turned off. At this time, the disk 2 has been unloaded to the take-out position (the two-dot chain line position in FIG. 5). When the user takes out the disk 2 at the take-out position, the detection lever 642 presses the first switch 16 and the first switch 16 is turned off.

Next, the configuration near the slot 4 will be described. FIG. 6 is an enlarged schematic diagram showing a configuration near the slot 4.
The holding member 4a includes movable pieces 4aa and 4aa that can move at both ends thereof. The moving pieces 4aa and 4aa are separated from the portions of the holding member 4a other than the moving pieces 4aa and 4aa. A concave storage chamber 30 is formed on the front surface of the housing 3 at a portion adjacent to the movable piece 4aa. An elastic member 71 is provided at the bottom of the storage chamber 30. A columnar leg portion 70 is accommodated in the accommodation chamber 30 and is urged toward the slot 4 by an elastic member 71. The leg 70 and the moving piece 4aa are connected.

  A motor 72 is disposed in the housing 3. A circular eccentric cam 73 is connected to the rotating shaft 72 a of the motor 72, and the side surface of the eccentric cam 73 faces the front surface of the housing 3 in which the slot 4 is provided. The connecting position between the rotating shaft 72 a and the eccentric cam 73 is a position that is deviated in the direction perpendicular to the slot 4 from the center of the eccentric cam 73.

An engagement groove 73 a is provided on the circumferential surface of the eccentric cam 73. A driven wheel 74 is engaged with the engagement groove 73a on the slot 4 side. The driven wheel 74 and the leg portion 70 are connected by a connecting rod 75.
A central portion of the connecting rod 75 is rotatably supported by a pivot 76 perpendicular to the front surface portion of the housing 3. At both ends of the connecting rod 75, pivot shafts 77 and 78 perpendicular to the front surface portion of the housing 3 are respectively provided. A driven wheel 74 and a leg portion 70 are rotatably connected to the respective pivot shafts 77 and 78. ing.

As indicated by the arrow in FIG. 6, the eccentric cam 73 rotates by the drive of the motor 72 and reciprocates in the direction orthogonal to the slot 4.
When the eccentric cam 73 moves away from the slot 4, the leg portion 70 approaches the slot 4 by the urging force of the elastic member 71, and the moving piece 4aa approaches the holding member 4b as shown by the arrow in FIG. At this time, the connecting rod 75 rotates about the pivot 76, and the driven wheel 74 is separated from the slot 4 and abuts against the eccentric cam 73. When the moving piece 4aa is close to the holding member 4b, the distance between the moving piece 4aa and the holding member 4b is sufficiently small with respect to the thickness of the disk 2.

  On the other hand, when the eccentric cam 73 approaches the slot 4, the eccentric cam 73 presses the driven wheel 74. Due to the pressure on the driven wheel 74, the connecting rod 75 rotates around the pivot 76, and the leg portion 70 moves away from the slot 4 against the urging force of the elastic member 71. Therefore, as shown by the arrow in FIG. 6, the moving piece 4aa is separated from the holding member 4b. In addition, the mechanism which consists of the motor 72 etc. which were mentioned above is connected with each moving piece 4aa, 4aa.

The driving of the motor 72 described above is controlled by the control unit. FIG. 7 is a block diagram showing a configuration near the control unit.
The control unit 11 includes a CPU (Central Processing Unit), and executes processing based on a control program described later. An ON or OFF signal is input to the control unit 11 from the first switch 16 to the third switch 18, and a control signal (for example, an eject signal indicating that the disc is ejected) is input from the signal input unit 12.

A drive signal is output from the controller 11 to the roller drive motor 15 and the motor 72, and the roller drive motor 15 and the motor 72 rotate forward and backward.
The control unit 11 is connected to the storage unit 13 and the recording / reproducing unit 5, and transmits / receives signals between the storage unit 13 and the recording / reproducing unit 5 to transmit / receive data, transmit drive signals, and the like. The storage unit 13 includes a ROM (Read Only Memory) that stores a control program related to processing executed by the control unit 11, and a RAM (Random Access Memory) that stores work variables generated during the execution of the control program. ing.

  Next, the movement process of the moving piece by the control unit 11 will be described. FIG. 8 is a flowchart for explaining the moving process of the moving piece when the disc is loaded. In the initial state, the eccentric cam 73 is close to the slot 4 and the moving piece 4aa is close to the holding member 4b.

  The controller 11 determines whether or not an ON signal is input from the first switch 16 (step S1), and waits until an ON signal is input from the first switch 16 (step S1: NO). When the ON signal is input from the first switch 16 (step S1: YES), the disk 2 is inserted in the slot 4, and the control unit 11 outputs a forward rotation signal to the motor 72 (step S2). At this time, the roller drive motor 15 rotates and the disk 2 is carried into the recording / reproducing unit 5. The motor 72 rotates positively by a predetermined number, and the moving piece 4aa is separated from the holding member 4b. In the direction perpendicular to the slot 4, the position of the moving piece 4aa is substantially the same position as the other holding members 4a, and the frictional force between the moving piece 4aa and the disk 2 during loading is reduced.

  Next, the controller 11 determines whether or not an on signal is input from the second switch 17 (step S3), and waits until an on signal is input from the second switch 17 (step S3: NO). When the ON signal is input from the second switch 17 (step S3: YES), the roller drive motor 15 is stopped, and the loading of the disk 2 into the recording / reproducing unit 5 is completed. The control unit 11 outputs a reverse rotation signal to the motor 72 (step S4). At this time, the motor 72 rotates in the reverse direction by a predetermined number, and the moving piece 4aa comes close to the holding member 4b.

When an eject signal is input from the signal input unit 12 to the control unit 11, the control unit 11 carries out the disk 2. FIG. 9 is a flowchart for explaining the moving process of the moving piece when the disc is unloaded.
The control unit 11 determines whether or not an eject signal is input from the signal input unit 12 (step S11), and waits until an eject signal is input from the signal input unit 12 (step S11: NO). When an eject signal is input from the signal input unit 12 (step S11: YES), the control unit 11 determines whether an off signal is input from the second switch 17 (step S12), and from the second switch 17 Wait until an OFF signal is input (step S12: NO).

  When an off signal is input from the second switch 17 (step S12: YES), the unloading of the disk 2 has started, and the control unit 11 outputs a forward rotation signal to the motor 72 (step S13). At this time, the roller drive motor 15 rotates and the disk 2 is unloaded from the recording / reproducing unit 5. The motor 72 rotates positively by a predetermined number, and the moving piece 4aa is separated from the holding member 4b. In the direction perpendicular to the slot 4, the position of the moving piece 4aa is substantially the same position as the other holding members 4a, and the frictional force between the moving piece 4aa and the disk 2 during unloading is reduced.

  Next, the control unit 11 determines whether or not an off signal is input from the third switch 18 (step S14), and waits until an off signal is input from the third switch 18 (step S14: NO). When an off signal is input from the third switch 18 (step S14: YES), the roller drive motor 15 is stopped and the disk 2 is carried out to the take-out position. The controller 11 outputs a reverse rotation signal (step S15). At this time, the motor 72 rotates in the reverse direction by a predetermined number, and the moving piece 4aa is close to the holding member 4b. Therefore, the disk 2 carried out to the take-out position is sandwiched between the moving piece 4aa and the holding member 4b.

  In the disk device according to the first embodiment, when the disk 2 is unloaded, the moving piece 4aa is brought close to the holding member 4b to firmly hold the disk 2 and reliably prevent the disk 2 from falling. be able to.

  Further, since the moving piece 4aa is moved away from the holding member 4b during loading or unloading of the disk 2, the frictional force between the moving piece 4aa and the holding member 4b and the disk 2 is reduced. Therefore, the first drive roller 62R6, the second drive roller 62R7, and the disk 2 can be prevented from slipping, and the disk 2 can be smoothly loaded and unloaded. Further, the burden on the transport mechanism 6 when the disk 2 is unloaded can be reduced.

  Further, the moving piece 4aa can be easily approached and separated from the disk 2 inserted into the slot 4.

  Further, since both sides of the disk 2 are held by the moving pieces 4aa, 4aa and the holding member 4b, the carried-out disk 2 is stabilized and the disk 2 can be reliably prevented from falling.

  The disk device 1 according to the first embodiment may be a vertical disk device or a horizontal disk device. Further, although the disk device 1 according to the first embodiment uses the eccentric cam 73 to move the movable piece 4aa, the present invention is not limited to this. For example, the leg portion 70 is made of a magnetic material, and as shown in FIG. 10, a solenoid 80 is provided around the leg portion 70, and the direction and current value of the current flowing through the solenoid 80 according to the output signal from the control unit 11. May be adjusted to control the movement of the moving piece 4aa. In this case, since the control unit 11 can adjust the moving direction and moving distance of the moving piece 4aa, the disc device 1 finely adjusts the distance between the moving piece 4aa and the holding member 4b to hold the disc 2 therebetween. Can be adjusted with high accuracy.

(Embodiment 2)

FIG. 11 is an enlarged schematic diagram showing a configuration near the slot of the disk device according to the second embodiment. Elastic members 79 are provided at the bottom of the storage chamber 30. A columnar leg 70 is accommodated in the accommodating chamber 30, and the leg 70 is connected to the elastic members 79, 79. The leg portion 70 is urged in a direction away from the slot 4 by the elastic members 79, 79. A driven wheel 74 is engaged with the engagement groove 73a on the side opposite to the slot 4.

As indicated by the arrows in FIG. 11, the eccentric cam 73 rotates by driving the motor 72 and reciprocates in the direction orthogonal to the slot 4.
When the eccentric cam 73 rotates and approaches the slot 4, the leg portion 70 is separated from the slot 4 by the urging force of the elastic members 79, 79, and the moving piece 4 aa is held by the holding member as shown by the arrow in FIG. 11. Separates from 4b. At this time, the connecting rod 75 rotates around the pivot 76, and the driven wheel 74 approaches the eccentric cam 73 and contacts the eccentric cam 73.

  On the other hand, when the eccentric cam 73 is separated from the slot 4, the driven wheel 74 is pressed from the eccentric cam 73. The driven wheel 74 is separated from the slot 4. The connecting rod 75 rotates about the pivot 76, and the leg portion 70 approaches the slot 4 against the urging force of the elastic members 79, 79. As shown by the arrow in FIG. 11, the moving piece 4aa is close to the holding member 4b. When the moving piece 4aa comes close to the holding member 4b, the distance between the moving piece 4aa and the holding member 4b is sufficiently small with respect to the thickness of the disk 2.

  Next, the movement process of the moving piece by the control unit 11 will be described. FIG. 12 is a flowchart for explaining the moving process of the moving piece when the disc is unloaded. In the initial state (when the disk 2 is loaded), the eccentric cam 73 is close to the slot 4 and the moving piece 4aa is separated from the holding member 4b.

  The control unit 11 determines whether or not an eject signal is input from the signal input unit 12 (step S21), and waits until an eject signal is input from the signal input unit 12 (step S21: NO). When an eject signal is input from the signal input unit 12 (step S21: YES), the control unit 11 determines whether or not an off signal is input from the third switch 18 (step S22), and from the third switch 18 Wait until an OFF signal is input (step S22: NO).

  When an off signal is input from the third switch 18 (step S22: YES), the disk 2 has been unloaded to the take-out position, and the control unit 11 outputs a normal rotation signal to the motor 72 (step S23). At this time, the motor 72 rotates positively by a predetermined number, and the moving piece 4aa approaches the holding member 4b. The disc 2 carried out to the take-out position is sandwiched between the moving piece 4aa and the holding member 4b.

  Next, the control unit 11 determines whether or not an off signal is input from the first switch 16 (step S24), and waits until an off signal is input from the first switch 16 (step S24: NO). When the off signal is input from the first switch 16 (step S24: YES), it is considered that the disk 2 has been taken out by the user. The controller 11 outputs a reverse rotation signal (step S25). At this time, the motor 72 rotates in the reverse direction by a predetermined number, and the moving piece 4aa is separated from the holding member 4b.

  Since the moving piece 4aa is separated from the holding member 4b when the disc 2 is carried in, the disc 2 is smoothly carried in.

  In the disk device according to the second embodiment, when the disk 2 is unloaded, the moving piece 4aa is brought close to the holding member 4b to firmly hold the disk 2 and reliably prevent the disk 2 from falling. be able to. Further, the moving piece 4aa can be easily approached and separated from the disk 2 inserted into the slot 4. Further, since both sides of the disk 2 are held by the moving piece 4aa and the holding member 4b, the carried-out disk 2 is stable and the disk 2 can be reliably prevented from falling.

  The disk device 1 according to the second embodiment uses the eccentric cam 73 to move the moving piece 4aa, but is not limited to this. For example, the leg portion 70 is made of a magnetic material, and as shown in FIG. 13, a solenoid 80 is provided around the leg portion 70, and the direction and current value of the current flowing through the solenoid 80 according to the output signal from the control unit 11. May be adjusted to control the movement of the moving piece 4aa. In this case, since the control unit 11 can adjust the moving direction and moving distance of the moving piece 4aa, the disc device 1 finely adjusts the distance between the moving piece 4aa and the holding member 4b to hold the disc 2 therebetween. Can be adjusted with high accuracy.

  Among the configurations of the disk device 1 according to the second embodiment, the same reference numerals are given to the same configurations as those in the first embodiment, and detailed description thereof is omitted.
