  In a disk device in which a disk is inserted through an insertion slot and carried in, the disk is carried into the housing and the disk is clamped by a rotation drive unit through a series of mechanism operations. Therefore, even when the center hole of the disk transferred by the transfer mechanism is displaced with respect to the rotation drive unit, the clamping operation for clamping the disk to the rotation drive unit is continuously performed. When such a clamping operation is performed, the disk may be unconstrained in a state where the disk is not securely clamped to the rotation drive unit, and the disk may remain in the housing in a free state. There is a possibility of failure that cannot be discharged outside the body.

  Further, as described in Patent Document 1, even in a disk storage type disk device in which a loaded disk is held by a support, the disk held by the selected support is not reliably clamped to the rotation drive unit. If the holding of the disk on the support is released at that time, the disk remains in the housing in a free state, and then the disk cannot be ejected outside the housing.

  In the invention described in Patent Document 2, when the disk is driven to rotate, there is a light quantity defect in the rotation check of the spindle motor provided in the rotation drive unit and the reflected light of the detection light emitted from the optical head. These checks are performed, and when it is determined that there is a disc clamp failure based on these check results, the rotation of the spindle motor is stopped.

  However, if the disc is rotated after performing the operation of clamping the disc to the rotation drive unit, it is possible to stop the disc rotation when it is determined that a disc clamping failure has occurred. The phenomenon that the disc cannot be ejected from the insertion slot of the housing tends to occur.

  In the invention described in Patent Document 3, when the clamping operation is completed, the disk is held so as not to move and a rotation command is given to the rotation driving unit, and the clamping operation is performed depending on whether or not the rotation driving unit actually rotates. It is possible to confirm whether it has been performed reliably. However, even in this operation, when the rotational load of the rotational drive unit is increased in a state where the disk is not reliably clamped, the rotational drive unit cannot be rotated, and the disk is not normally clamped. It is possible to misrecognize that the disc is clamped.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and provides a disk device capable of confirming whether or not a disk is normally clamped to a rotary drive unit after the disk is supplied to the rotary drive unit and a clamping operation is performed. It is intended to provide.

The disk device according to the present invention includes a rotation drive unit (82) on which the disk (D) is installed, a clamp member (86d) for clamping the disk (D) to the rotation drive unit (82), and a disk mounted on the rotation drive unit. A transfer mechanism (17) for transferring to (82);
The disc (D) is moved in a standby position where the transfer mechanism (17) is separated from the outer peripheral edge of the disc (D) clamped by the rotation drive unit (82) and a position where the transfer drive unit (82) can be clamped by the rotation drive unit (82). A power transmission section (16) that is moved between the holding movement operation positions;
A detection member for detecting whether or not the disk (D) is in a position where it can be clamped to the rotation drive unit (82);
After the disk (D) is held at a position where it can be clamped to the rotation drive unit (82) by the transfer mechanism (17) in the transfer operation position, and after the clamp member (86d) performs the clamp operation, the clamp confirmation operation And a control unit (301) for performing
In the clamp confirmation operation, a command to move the transfer mechanism (17) toward the standby position is given, and it is detected by the detection member that the disk (D) remains in a position where it can be clamped to the rotation drive unit (82). Then, it is determined that the disk (D) has been clamped normally, and if it is detected that the disk (D) has moved from a position where it can be clamped to the rotation drive unit (82), it is determined that the clamp is abnormal. Is.

  In the present invention, after the disk carried into the housing from the insertion port is supplied to the rotation drive unit and the clamping operation is performed, it is possible to confirm whether or not the disk is securely clamped to the rotation drive unit. it can. Or, whether any of a plurality of disks stored in the housing is selected and supplied to the rotation drive unit and then clamped, and then the disk is securely clamped to the rotation drive unit. Can be confirmed. Therefore, the rotation drive unit rotates while the clamp is in an abnormal state, and the disk is damaged, or the disk is detached from the rotation drive unit and falls into the housing, so that the disk cannot be ejected out of the housing. It can be prevented in advance.

  In the present invention, when it is determined that the disk (D) is normally clamped, the transfer mechanism (17) is continuously moved to the standby position, and the disk drive mode is entered. If it is determined that the clamp is abnormal, the moving direction of the transfer mechanism (17) is changed to return to the transfer operation position, and the disk (D) is ejected from the rotation drive unit (82).

  In this disk device, the clamping operation is performed in a state where the disk is held by the transfer mechanism, and after the clamping operation is completed, the transfer mechanism leaves the disk and shifts to the disk drive mode. Whether or not the disk is normally clamped can be confirmed only by monitoring the detection member when the transfer mechanism in the series of operations moves away from the disk. Therefore, when the clamping is normally performed, it is possible to immediately shift to the disk drive mode, and no special time is required for confirming the clamping operation, and the operation processing time can be shortened.

  For example, according to the present invention, the transfer mechanism (17) includes rollers (112, 113) for holding a disk (D), and when the transfer mechanism (17) is moved toward the standby position, The rollers (112, 113) are rotated in the transport direction opposite to the moving direction of the transfer mechanism (17).

  The transfer mechanism (17) includes rollers (112, 113) for holding the disk (D). When the transfer mechanism (17) is moved toward the transfer operation position, the roller ( 112, 113) are rotated in the transport direction opposite to the moving direction of the transfer mechanism (17).

  Alternatively, when the transfer mechanism (17) has rollers (112, 113) for holding the disk (D) and the disk (D) is ejected from the rotation drive unit (82), the transfer mechanism (17) is moved toward the standby position, and the rollers (112, 113) are rotated in the same conveying direction as the moving direction of the transfer mechanism (17).

  Further, according to the present invention, when the detection member is loaded to a position where the disk (D) transferred by the transfer mechanism (17) can be clamped to the rotation drive unit (82), the disk (D) is loaded. A loading completion detection member (Fe) to be detected. In this case, the disk (D) is moved by the loading completion detection member (Fe) within the predetermined period after giving a command to move the transfer mechanism (17) toward the standby position. If it is detected that it has moved from a position where it can be clamped, it is determined that the clamp is abnormal.

  In the present invention, the control unit (301) rotates the disc (D) held by the transfer mechanism (17) in the transfer operation position after performing the clamp operation by the clamp member (86d). When a rotation command is given to the drive unit (82) and rotation of the rotation drive unit (82) is not detected, the process proceeds to the clamp confirmation operation. When rotation of the rotation drive unit (82) is detected, it is determined that the clamp is abnormal. can do.

  In the above configuration, after the clamp operation is performed on the disk, first, the rotation drive unit is rotated to perform a first confirmation as to whether the clamp has been normally performed, and then the clamp confirmation operation as a second confirmation. Therefore, it can be accurately confirmed in two stages whether or not the disc has been clamped.

  However, the present invention may omit the first confirmation and perform only the clamp confirmation operation.

  Further, according to the present invention, the clamp member (86d) is a self-clamping claw that protrudes from the rotary table (86) provided in the rotation drive unit (82) and assumes a clamping posture.

  However, the clamp member may move from a position away from the rotation driving unit to a position where the rotation driving unit is pressurized, and clamp the disk with the rotation driving unit.

  In the disk device of the present invention, after the disk inserted from the insertion slot is installed in the rotation drive unit and the clamping operation is performed, or the disk stored in the housing is selected and installed in the rotation drive unit. After the clamping operation is performed, it can be confirmed with high probability whether or not the clamping has been normally performed. Therefore, it is possible to prevent the rotation drive unit from rotating with a defective clamp and damaging the disk or remaining in the housing without being restrained.

  According to the present invention, the clamping operation is performed in a state where the disk is held by the transfer mechanism, and after the clamping operation is completed, the transfer mechanism moves away from the disk and shifts to the disk drive mode. Whether or not the disk is normally clamped can be confirmed only by monitoring the detection member when the transfer mechanism in the series of operations moves away from the disk. Therefore, when the clamping is normally performed, it is possible to immediately shift to the disk drive mode, and no special time is required for confirming the clamping operation, and the operation processing time can be shortened.

The holding part 137c is located closer to the center of curvature of the sliding locus of the switching member 91 than the non-acting part 137a.

  Therefore, while the switching member 91 further slides in the direction (e) shown in FIG. 6 from the position shown in FIG. 6 to the position shown in FIG. The shaft 138 is moved counterclockwise, and the drive lever 135 is rotated counterclockwise. As a result, as shown in FIG. 7, the transfer unit 17 is rotated counterclockwise around the fulcrum shaft 131 to reach the transfer operation position. In the transfer operation position shown in FIG. 7, the drive shaft 133 is located at the Y2 side end of the guide hole 15c, the transmission shaft 138 is held by the holding portion 137c of the unit control slot 137, and the transmission shaft 138 is Since it is held by the holding portion 137c of the control slot 137, the transfer unit 17 is restrained at the transfer operation position shown in FIG.

The power is transmitted from the spur gear 147 a to the large-diameter spur gear 146 b of the integrated gear 146 and further transmitted from the small-diameter spur gear 146 a to the roller gear 144.

  Since the rotational power of the third motor M3 is transmitted to the roller gear 144 via the integral gear 141 that rotates coaxially with the fulcrum shaft 131, the transfer unit 17 is moved from the standby position to the transfer operation position with the fulcrum shaft 131 as a fulcrum. The roller shaft 111 can be driven independently of the operation of rotating to the right. The disk storage type disk apparatus 1 of the present invention is provided with a transfer unit moving means for rotating the transfer unit 17 from the standby position to the transfer operation position, and a roller driving means for rotating the transfer rollers 112 and 113 separately.

Each of the latching portions of the six supports 21 is arranged to be latched at each of the five adjacent pitches of the selection groove 152. Therefore, when the selection shaft 151 rotates counterclockwise when viewed from above, the support members 21 are sent downward along the selection shaft 151 one by one, and when the selection shaft 151 rotates clockwise, the support member 21 is A single sheet is sent upward along the selection axis 151. Then, when any one of the supports 21 hooked on the sparse pitch portion 152c reaches the selection position (a) shown in FIG. 2B, the support 21 at the selection position (a) An interval in the vertical direction in which the drive unit 14 can enter is provided between the support body 21 located in the dense pitch portion 152b.

  The three selection shafts 151 are rotated in synchronization with each other. As the mechanism, a thin small gear (not shown) is integrally fixed to the upper end of each selection shaft 151. Further, a thin ring gear having a large diameter is rotatably provided on the lower surface of the ceiling surface 11 of the upper housing 5, and all the small gears are engaged with the ring gear.

  As shown in FIG. 2B, a rotating shaft 99a is rotatably supported on the lower surface of the ceiling surface 11 of the upper housing 5. The transmission gear 99 is fixed to the lower end of the rotating shaft 99a, and the transmission gear 99 can mesh with the switching gear 98 of the second power transmission unit 16 shown in FIG. A thin gear 99b is fixed to the upper end of the rotating shaft 99a, and the thin gear 99b meshes with the ring gear. That is, in the selection operation for moving any one of the six support bodies 21 to the selection position (a), the second motor M2 provided in the second power transmission unit 16 is driven, and the power is switched to the switching gear. Transmission from 98 to the transmission gear 99 is performed by rotating the ring gear.

  As shown in FIG. 10, each support 21 is provided with holding claws 155, 156, and 157. Each of the holding claws 155, 156, and 157 is supported by the support 21 so as to be able to rotate around the selection shaft 151, and each of the holding claws 155, 156, and 157 is rotated in the direction in which the disk can be held. It is energized. When the disk D transferred by the transfer unit 17 is supplied to the lower surface of the support 21 at the selected position (a), the disk D is held by the support 21 and the holding claws 155, 156, and 157. . A holding release function is provided in the housing 2. When the center hole Da of the disk D supported by the support 21 at the selected position (a) is clamped to the rotary table 86, each holding claw 155 is provided. , 156, 157 are rotated in a direction to oppose the rotation urging force, and the holding of the disk D by the support 21 is released.

(Detection means)
FIG. 9 shows detection means provided in each part of the disk storage type disk device 1.

  Inside the housing 2, detection elements Fe for detecting completion of loading are provided at corners of the left side surface 9 and the rear surface 10. The detection element Fe is provided with a light emitting element and a light receiving element facing each other. This detection element Fe is provided only in one place in the housing 2 and is disposed at the same height as the support 21 moved to the selection position (a).

  A loading detection member 200 is provided on the support 21 in the disk storage area 20. The loading detection members 200 are individually provided on all the supports 21, and each of the supports 21 supports the loading detection member 200 so that it can rotate around the selection shaft 151. Each loading detection member 200 provided on each support 21 is always urged to rotate clockwise as shown in FIG. 9 by a torsion spring (not shown). A holding claw 156 shown in FIG. 10 is integrally formed at the tip of one arm portion 201 extending from the loading detection member 200.

  A light shielding portion 203 is provided at the tip of the other arm portion 202 extending from the loading detection member 200. When the loading detection member 200 is rotated clockwise as shown in FIG. 203 enters the detection element Fe for detecting the completion of loading, and the light from the light emitting element is blocked by the light blocking portion 203, and the light is not received by the light receiving element (OFF). In this embodiment, the loading detection member 200 and the detection element Fe constitute a loading completion detection mechanism.

  As shown in FIG. 10, each support 21 provided in the disk storage area 20 is configured as shown in FIG. 10 except that the disk D supported by the support 21 is clamped on the rotary table 86 of the rotation drive unit 82. The holding claws 155, 156, and 157 protrude to positions where the disk D can be held. As shown in FIG. 9, the loading detection member 200 provided with the holding claws 156 also rotates in the clockwise direction, and the light shielding portion 203 is moved. The sensor element Fe can enter the inside.

  When none of the plurality of supports 21 has moved to the selected position (a), the light shielding unit 203 does not intervene in the detection element Fe, and the detection element Fe receives light generated from the light emitting element. It is detected by the element and the detection output is turned ON. When any one of the supports 21 is selected and reaches the selected position (a) by the operation of the support selection means 22, the light shielding portion 203 provided on the selected support 21 intervenes in the detection element Fe. The light from the light emitting element to the light receiving element is blocked, and the detection output of the detection element Fe is switched to OFF. Therefore, the mechanism control unit 301 shown in FIG. 12 can confirm whether or not the support 21 to be selected has reached the selection position (a) by monitoring the detection output of the detection element Fe.

  Further, when the disk D loaded by the transfer unit 17 is sent to the support body 21 in a state where the support body 21 has been moved to the selected position (a) and stopped, the disk D is held by the support body 21 and each holding unit. While being held by the claws 155, 156 and 157, the arm portion 201 is pushed by the outer peripheral edge of the disk D being fed. Therefore, the loading detection member 200 rotates counterclockwise, the light shielding portion 203 comes out of the detection element Fe, and the detection output of the detection element Fe is switched from OFF to ON. By this detection operation, it can be recognized that the loading of the disk D onto the support 21 at the selected position (a) is completed.

  As shown in FIGS. 9 and 10, the transfer unit 17 is provided with a pair of optical detection elements F1 and F2 that function as insertion detection members. The optical detection elements F1 and F2 are provided in the unit frame 100 of the transfer unit 17 shown in FIG. 8, and sandwich the disk passing between the holding portion 106 of the sliding member 105 and the transfer rollers 112 and 113. The light-emitting element is provided on one side and the light-receiving element is provided on the other side so as to face each other.

  As shown in FIGS. 9 and 10, the optical detection elements F1 and F2 are arranged on the left and right sides with respect to the center of the transferable width of the disk D in the transfer unit 17 (the center of the width dimension W of the insertion port 23 shown in FIG. 1). Are arranged at equal distances. Each of the optical detection elements F1 and F2 faces an intermediate portion 114 provided between the first transfer roller 112 and the second transfer roller 113, and is provided closer to the insertion port 23 than the intermediate portion 114. ing.

  As shown in FIG. 10, when the transfer unit 17 is in the standby position, the optical detection elements F <b> 1 and F <b> 2 are located between the intermediate portion 114 and the insertion port 23. When the disk D is inserted from the insertion port 23, the optical detection elements F1 and F2 are blocked by the disk D before the front peripheral edge hits the first transfer roller 112 and the second transfer roller 113, The detection outputs of both optical detection elements F1, F2 are switched from ON to OFF. Thereby, it can be detected that the disk D is inserted from the insertion slot 23.

  Based on this detection operation, the third motor M3 shown in FIG. 3 is started, and the first transfer roller 112 and the second transfer roller 113 start to rotate in the loading direction. The disk held between the transfer rollers 112 and 113 and the holding unit 106 is sent into the housing 2 by the rotation of the transfer rollers 112 and 113, and the transfer unit 17 is further rotated counterclockwise. , And sent toward the lower surface of the support 21 at the selected position (a).

  As shown in FIG. 9, when the disk D is loaded on the support 21 at the selected position (a) by the rotation of the transfer rollers 112 and 113 after the transfer unit 17 is rotated toward the transfer operation position, The loading detection member 200 is pushed by the disk D, the light shielding portion 203 is separated from the detection element Fe, and the detection element Fe is switched from OFF to ON. As described above, when the detection element Fe is switched to ON, the optical detection elements F1 and F2 are detected so as to be located immediately inside the peripheral edge on the insertion port 23 side of the disk D having a normal outer diameter. The positional relationship between the element Fe and the optical detection elements F1 and F2 is set. Therefore, when the detection output of the optical detection elements F1 and F2 continues to be OFF when the detection element Fe is turned on and the completion of the loading of the disk D is detected, the outside of the disk D in the loading completion state is removed. It can be recognized that the diameter is normal. On the contrary, if the optical detection elements F1 and F2 are switched from OFF to ON before the detection element Fe is switched ON, it can be determined that the outer diameter of the disk D being transported is abnormal.

  As shown in FIGS. 9 to 11, a pair of detection members 251 and 252 are provided immediately inside the insertion slot 23. The detection members 251 and 252 are detection pins extending vertically, and each detection pin vertically traverses the insertion port 23 inside the housing 2. The detection member 251 and the detection member 252 are mounted on a slider (not shown) and supported so as to be linearly movable in the X1-X2 direction independently of each other. And the detection member 251 and the detection member 252 are urged | biased by the direction which mutually approaches with the spring.

  A detection plate 253 extending in the X1-X2 direction is fixed to one detection member 251, and a detection plate 254 extending in the X1-X2 direction is also fixed to the other detection member 252. In the housing 2, mechanical operation type detection switches SW 1, SW 3, and SW 4 that are operated by the detection plate 253 are provided, and the same mechanical operation type detection switch SW 2 that is operated by the other detection plate 254 is provided. ing.

  In FIG. 11, the detection member 251 and the detection member 252 are in the initial position closest to each other by the spring. At this time, the detection switch SW1 is switched ON by the detection plate 253, and the detection switch SW2 is switched ON by the detection plate 254. When the disk D is carried into the housing 2, the detection member 251 is pushed in the X2 direction by the outer peripheral edge of the disk D, the detection member 252 is pushed in the X1 direction, and the detection switches SW1 and SW2 are immediately turned on. Turns off. By confirming that the detection switches SW1 and SW2 are both OFF, the operation in which the disk D is carried into the housing is being performed, and the operation in which the disk D is carried out toward the insertion slot 23. Can be recognized.

  When the center D0 of the disk D moves slightly inward from the insertion slot 23, the detection member 251 is moved the longest distance in the X2 direction, and the detection switch SW4 is switched from OFF to ON for a short time by the detection plate 253. As shown in FIG. 11, when the disk D is carried into the housing 2 and the detection member 251 and the detection member 252 return to the initial positions, the detection switches SW1 and SW2 are switched from OFF to ON again. Therefore, when the disk D is being carried in, the detection switches SW1 and SW2 are first switched from ON to OFF, and then the detection switch SW4 is switched from OFF to ON for a short time and then further OFF, and the detection switch SW1. By confirming that SW2 returns from OFF to ON, it can be determined that the disk D having a normal outer diameter has been loaded.

  Further, when the disk D in the housing 2 is ejected from the insertion slot 23, the detection member 251 is moved in the X2 direction by the outer peripheral edge of the disk D, and the detection switch SW3 is turned from OFF to ON by the detection plate 253. In the latter half of the process in which the disk D is ejected, the detection member 251 returns to the X1 direction, and the detection switch SW3 is switched from ON to OFF. During the disk unloading operation, after the transfer unit 17 returns to the standby position shown in FIG. 10, the third motor M3 is stopped and the first transfer is performed when the detection switch SW3 is switched from ON to OFF. The rotation of the roller 112 and the second transfer roller 113 is stopped. In FIG. 10, the position of the detection member 251 at this time is indicated by (i). When the detection member 251 returns to the position (i), the rotation of the transfer rollers 112 and 113 is stopped, so that the disk D is ejected in a state where a part of the disk D is held inside the housing 2. Can be stopped.

  When waiting for the insertion of the disk D, as shown in FIG. 10, the interval between the detection members 251 and 252 is set wider than the interval between the optical detection elements F1 and F2. Therefore, when the disk D is inserted from the insertion port 23, the optical detection elements F1 and F2 are turned off first, and the disk insertion is detected, and the transfer rollers 112 and 113 are started in the loading direction. Then, after the carry input is given to the disk D, the outer peripheral edge of the disk D hits the detection members 251 and 252. Therefore, when the disk D is inserted by hand, the resistance for moving the detection members 251 and 252 is not felt by the hand, and the insertion feeling of the disk can be improved.

  As shown in FIG. 3, the lower casing 3 is also provided with an operation detection switch SWa. The rack member 32 of the first power transmission unit 12 moves a predetermined distance in the Y1 direction, and the drive slider 85 is moved in the Y1 direction by the drive pin 41 of the switching member 38 that moves together with the rack member 32. When the clamp switching member 80 is operated by the moving force and the clamp pawl 86d assumes the clamping posture as shown in FIG. 5, the operation detection switch SWa is switched from OFF to ON. The operation detection switch SWa functions as a clamp completion detection member.

Is output to the mechanism control unit 301.

(Operation)
Next, the overall operation of the disk storage type disk device 1 of the present invention will be described.
FIG. 10 is a plan view showing a state in which the disc storage type disc device 1 is set to a home position waiting for disc insertion. FIGS. 9 and 11 are plan views showing disc insertion and carry-in operations. In the flowcharts shown in FIG. 13 to FIG. 16, each operation stage controlled by the mechanism control unit 301 is indicated by step (S).

(Disc insertion standby mode)
The home position for waiting for the insertion of the disk D in the disk storage type disk device 1 is an intervention position where the drive unit 14 intervenes in the disk storage area 20 as shown by a solid line in FIG. It is in a standby position along the inside of the front surface 7 of the housing 2.

  When an operation for designating any one of the plurality of supports 21 is performed using an operation unit or a remote controller located on the Y1 side of the front surface 7 of the housing 2, the first power transmission unit 12 shown in FIG. The first motor M1 is started, the rack member 32 and the switching member 38 are driven in the Y2 direction, and a drive slider 85 provided on the lower surface of the unit support base 13 is driven by the drive pin 41 fixed to the switching member 38. As shown in FIG. 3, the drive unit 14 is moved in the Y2 direction, and the drive unit 14 is rotated to the retracted position along the inner side of the right side surface 8 of the housing 2 as indicated by a broken line in FIG.

  Then, the second motor M2 of the second power transmission unit 16 shown in FIG. 6 is started, the power acts on the transmission gear 99 from the switching gear 98, and the selection shaft 151 of the support body selection means 22 is driven. . The support 21 is moved up and down by the selection groove 152 which is a screw groove of the selection shaft 151, and the support 21 to hold the disk D reaches the selection position (a). After the support 21 is stopped at the selected position (a), the rack member 32 and the switching member 38 are moved in the Y1 direction by the first motor M1 of the first power transmission unit 12, which is shown by a solid line in FIG. Thus, the drive unit 14 is rotated to the intervention position shown in FIG. 10, and the home position is set.

  In this home position, the lock switching member 42 of the first power transmission unit 12 shown in FIG. 1 is moved to the Y2 side, the lock member 54 is moved to the X2 side, and the lock member 61 shown in FIG. Is moved to the X2 side, the restraint shaft 77 fixed to the unit support base 13 is held by the restraint portion 56a of the lock control hole 56 formed in the lock member 54, and the restraint shafts 78, 78 are locked members. The lock control holes 62 and 62 formed in 61 are held by the restraining portions 62 a and 62 a. Therefore, the unit support base 13 is held in a lowered posture so as to approach the bottom surface 6 of the housing 2. The drive unit 14 mounted on the unit support base 13 is also lowered to a position approaching the bottom surface 6. As shown in FIG. 10, the rotation drive unit 83 on the drive unit 14 that has moved to the intervention position is in the selected position. It is located below the support 21 in (a).

(Disc loading operation)
In S1 (step 1) of FIG. 13, when a disk insertion operation is performed on the operation unit, the process proceeds to S2, the shutter 24 shown in FIG. 2B operates, and the insertion slot 23 is opened.

  In S8, it is monitored whether any of the optical detection elements F1 and F2 is switched from ON to OFF. In S9, a timer is started when it is detected in S2 that the shutter is opened, and it is monitored whether or not the optical detection elements F1 and F2 are turned off within a predetermined time, and it is determined that neither of them is turned off. If it is determined that the disk D is not inserted, the process proceeds to S10, the shutter 24 is closed, and the process returns to S1 to wait for a new disk insertion operation.

  In S8, when it is determined that one of the optical detection elements F1 and F2 is turned OFF, the process proceeds to S11 and the disk loading operation is performed. In this disk loading operation, first, the third motor M3 of the third power transmission unit 19 shown in FIG. 3 is started with the transfer unit 17 stopped at the standby position approaching the front surface 7 as shown in FIG. Then, the first transfer roller 112 and the second transfer roller 113 rotate in the disk loading direction. The disk D is sandwiched between the transfer rollers 112 and 113 and the sandwiching unit 106 and starts to be transported toward the inside of the housing 2.

  In S12 shown in FIG. 13, when the third motor M3 is started and the transfer rollers 112 and 113 are started, a timer is started by the mechanism control unit 301, and one of the detection switches SW1 and SW2 is turned on within a predetermined time. Monitor whether it switches from ON to OFF. If neither of the detection switches SW1 and SW2 is turned OFF within a predetermined time after the third motor M3 is started, it is determined that the disk D has been pulled out before reaching the transfer rollers 112 and 113, and the process proceeds to S14. Then, the third motor M3 is stopped, and the transfer rollers 112 and 113 are stopped.

  In S12, when the detection switch SW1 or SW2 is switched to OFF, the rotation of the transfer rollers 112 and 113 is continued as it is. The disk D is carried into the housing 2 along the insertion center line Oa shown in FIG. When the detection member 251 is pushed in the X2 direction at the outer peripheral edge of the disk D, and the detection switch SW3 or the detection switch SW4 is switched from OFF to ON by the detection plate 253, the second power transmission unit shown in FIGS. The 16 second motors M2 are started, the meshing of the switching gear 98 and the output gear 94 is released, and the switching member 91 is driven in the direction (e). The drive lever 135 is rotated counterclockwise by the drive inclined portion 137 b of the unit control slot 137 formed in the switching member 91, and the transfer unit 17 rotates counterclockwise around the fulcrum shaft 131. And the transfer operation position shown in FIGS. 9 and 11 is set.

  Even after the transfer unit 17 is set to the transfer operation position and stopped, the operation of the third motor M3 continues, and the disk D is carried into the housing 2 by the rotation force of the transfer rollers 112 and 113, and the disk D D is fed into the support 21 at the selected position (a).

  In S12 shown in FIG. 13, when it is determined that the detection switch SW1 or SW2 has been turned OFF, the mechanism control unit 301 starts a timer, and when both the detection switches SW1 and SW2 do not return to ON within a predetermined time in S16, It is determined that the disk D has not been normally loaded, and the process proceeds to S17 to forcibly carry out the disk D. In the forced carry-out operation of S17, the third motor M3 is reversely rotated, the first transfer roller 112 and the second transfer roller 113 are rotated in the carry-out direction, and the second motor M2 is started, and FIG. 7 is moved in the direction (d) and the transfer unit 17 is rotated in the clockwise direction to return to the standby position shown in FIG.

  In this forced ejection operation, the disk D is completely ejected from the insertion slot 23, the detection members 251 and 252 return to the closest initial position, and the ejection operation is stopped when both the detection switches SW1 and SW2 are turned on. Alternatively, when the detection member 251 returns to the position indicated by (i) in FIG. 10 and the detection switch SW3 is turned from ON to OFF, the forced ejection operation is stopped, and a part of the disk D is The discharging operation may be stopped while being held in the housing 2.

(Disc loading detection)
In S21 shown in FIG. 14, it is monitored whether or not the detection element Fe for detecting completion of loading shown in FIG. 9 is switched from OFF to ON. In S22, a timer is started from the time when both of the detection switches SW1 and SW2 are switched on in S15, and it is monitored whether or not a predetermined time has elapsed. If the detection element Fe is not turned ON within a predetermined time, the disk D being transported may not be able to move into the support 21 and may be stopped. In this case as well, the process proceeds to S17 and the disk is immediately D is forcibly discharged.

  In S21, when it is detected that the detection element Fe is turned on, the mechanism control unit 301 determines that the disk D having a normal outer diameter is loaded on the support 21 at the selected position (a). to decide. At this time, the process proceeds to S23, and energization of the third motor M3 is continued for a short time, and the driving force in the carry-in direction is continuously applied to the transfer rollers 112 and 113 for a predetermined time. In step S24, the third motor M3 is stopped, and the rotation of the transfer rollers 112 and 113 is stopped. At this time, the transfer unit is in the transfer operation position shown in FIGS. 9 and 11, and the disk D is held by the stopped transfer rollers 112 and 113 and the holding unit 106. Further, the center hole Da of the loaded disk D coincides with the convex portion 86b of the rotary table 86 located below the disk D, and it is possible to shift to S25 and shift to the disk clamping operation.

(Disc clamp operation)
The clamping operation after loading the disc (S25) is performed based on the flow shown in FIG.
In the disk clamping operation, as shown in FIGS. 9 and 11, the first power transmission unit 12 shown in FIG. 1 is further obtained in a state where the drive unit 14 stops at the intervention position and the transfer unit 17 stops at the transfer operation position. The rack member 32 is driven in the Y1 direction. In this process, the switching member 38 does not first move in the Y1 direction, the connecting rotation lever 43 is driven in the counterclockwise direction, and the lock member 54 is moved in the X1 direction, and the lock shown in FIG. The member 61 is also moved in the X1 direction. The restraint shaft 77 is lifted by the lifting portion 56 b of the lock control hole 56 provided in the lock member 54, and the restraint shafts 78, 78 are lifted by the lifting portion 62 b of the lock control hole 62 provided in the lock member 61. Therefore, the unit support base 13 is lifted, and the convex portion 86b (see FIG. 4) of the rotary table 86 provided in the drive unit 14 at the intervention position is held on the support 21 at the selected position (a). D enters the center hole Da of D.

  Thereafter, the connecting rotation lever 43 stops, the lock switching member 42 stops, the state where the unit support base 13 is lifted is maintained, and the switching member follows the movement of the rack member 32 in the Y1 direction. 38 moves in the Y1 direction, and the drive slider 85 positioned on the lower surface of the unit support base 13 is moved in the Y1 direction by the drive pin 41 fixed to the switching member 38. At this time, as indicated by a broken line in FIG. 3, the clamp switching member 80 provided in the drive unit 14 in the intervention position moves to the rotation free end side of the drive unit 14, and as shown in FIG. The clamp claw 86d in the 86 has a clamp posture in which it protrudes to the periphery.

  Whether or not the series of clamping operations is completed is determined by moving the rack member 32 moving in the Y1 direction to the clamping operation completion position, and the operation detection switch SWa shown in FIG. Is detected. When the operation detection switch SWa is turned on, the first motor M1 of the first power transmission unit 12 is stopped and the rack member 32 is stopped.

  As shown in FIG. 15, in S31, when it is detected that the operation detection switch SWa is turned on, in S32, the mechanism control unit 301 gives a drive command to the servo motor driver 305 shown in FIG. The spindle motor Ms of the rotation drive unit 82 provided in the drive unit 14 is energized for a short time.

  In S33, it is detected whether or not the spindle motor Ms has rotated at this time. Since the spindle motor Ms is a servo motor and the FG is provided in the rotation detection unit, when the spindle motor Ms rotates, the rotation detection pulse from the FG is fed back to the servo motor driver 305, thereby the mechanism control unit 301. Then, it can be recognized that the spindle motor Ms has rotated. Alternatively, it is possible to detect whether or not the spindle motor Ms has rotated by monitoring the drive current applied to the coil of the spindle motor Ms.

  As shown in FIG. 5, the disc D is clamped between the transfer rollers 112 and 113 of the transfer unit 17 and the clamping unit 106 when the clamping claw 86 d is in the clamping posture and the clamping operation is completed. Therefore, if the disk D is normally clamped by the clamp claws 86d, the spindle motor Ms should not rotate even if the spindle motor Ms is energized. Therefore, in S34, the time after starting the spindle motor Ms is measured, and if the spindle motor Ms does not rotate even after the predetermined time has elapsed, it is highly likely that the disc D has been normally clamped. The process proceeds to S60, and the process proceeds to the clamp confirmation operation.

  In S33, when the spindle motor Ms rotates, there is a high possibility of a clamp abnormality. Clamping abnormality occurs when the inner diameter of the center hole Da of the disk D held on the support 21 is larger than the prescribed one and the center hole Da of the disk D cannot be properly clamped by the clamping claws 86d. Alternatively, it occurs when the clamp pawl 86d protrudes to the clamp posture in a state where the convex portion 86b of the rotary table 86 is not fully within the center hole Da of the disk D.

  In this case, the process proceeds to S35, where the first motor M1 of the first power transmission unit 12 shown in FIG. 1 is started, the rack member 32 is moved in the Y2 direction, and the drive pin 41 of the switching member 38 is used. 3, the drive slider 85 shown in FIG. 3 is moved in the Y2 direction, the clamp switching member 80 is operated, and the clamp pawl 86d is moved back into the convex portion 86b of the rotary table 86 as shown in FIG. . Further, the rack member 32 is moved in the Y2 direction, the connecting rotation lever 43 is rotated, the lock switching member 42 is moved in the Y2 direction, and the lock member 54 and the lock member 61 are moved in the X2 direction. The restraint shaft 77 is restrained by the restraint portion 56 a of the lock control hole 56 provided in the lock member 54, and the restraint shafts 78, 78 are restrained by the restraint portion 62 a of the lock control hole 62 provided in the lock member 61. Then, the unit support base 13 is lowered. Accordingly, the drive unit 14 is also lowered, and the convex portion 86 b of the rotary table 86 comes out of the center hole Da of the disk D.

  Thereafter, the process proceeds to S36, the third motor M3 is started, the transfer rollers 112 and 113 are rotated in the discharging direction, and the second motor M2 is operated to move the transfer unit 17 to the standby position shown in FIG. The disc D is ejected from the insertion slot 23 after returning. In this discharge operation, the detection member 251 moves in the X2 direction at the outer peripheral edge of the disk D, the detection switch SW3 is turned ON by the detection plate 253, and the detection member as the disk D is discharged from the insertion port 23. When 251 returns to the X1 direction and the detection switch SW3 is turned OFF, the rotation of the transfer rollers 112 and 113 is stopped. Therefore, the disc D to be ejected is held in a state where a part thereof remains in the housing 2.

(Clamping operation after selecting support)
When any of the disks D stored in the disk storage area 20 is selected and driven, the drive unit 14 is moved to the retracted position, and the transfer unit 17 is moved to the standby position. Then, the switching gear 98 shown in FIG. 6 is meshed with the output gear 94 and the transmission gear 99, the selection shaft 151 of the support body selecting means 22 is driven by the power of the second motor M2, and any of the support bodies 21 is driven. Is moved to the selected position (a) (S40 in FIG. 16).

  When the support selecting operation is completed, in S41, the drive unit 14 is rotated to the intervention position shown in FIG. 9, and the rotation drive unit 83 is moved to the center hole of the disk D held by the support 21 at the selected position (a). Oppose Da from below.

  In S42, the second motor M2 shown in FIGS. 6 and 7 is started, the switching member 91 is moved in the (e) direction, and the transfer unit 17 is rotated counterclockwise. At the same time, the third motor M3 is started to rotate the transfer rollers 112 and 113 in the carry-out direction, and when the transfer unit 17 moves to the transfer operation position shown in FIG. The motor M3 is stopped. With this operation, the disk D is held by the holding unit 106 of the transfer unit 17 and the transfer rollers 112 and 113.

  Thereafter, the process proceeds to S25 shown in FIG. 15 to perform a clamping operation, further rotate the spindle motor Ms to check whether the clamping operation is normal, and if it is determined that there is a high possibility of normal clamping, The process proceeds to the clamp confirmation operation S60.

(Clamp check operation)
FIG. 17 shows the operation of the first embodiment of the clamp confirmation operation S60.
In S33 of FIG. 15, when the rotation command is given to the spindle motor Ms after the completion of the clamping operation and the rotation driving unit 82 does not rotate, there is a high probability that the clamping operation is normally performed. Still, for example, when the drive unit 14 is raised, the convex portion 86b of the rotation drive unit 82 cannot enter the center hole Da of the disk D and the disk D is pressed against the support 21 by the rotation drive unit 82. The clamp claw 86d may protrude from the lower surface of the disk D to reach a clamp completed state. In this case, even if a rotation command is given to the spindle motor Ms in S32, since the rotation drive unit 82 is pressed against the disk D, the load of the rotation drive unit 82 becomes large and the rotation cannot be performed, and the clamp is normally performed. It will be in the same state as it was.

  Therefore, in the clamp confirmation operation S60, when it is determined in S33 and S34 shown in FIG. 15 that the rotation drive unit 82 does not rotate, a further confirmation operation is performed to drive the disk while the disk D is normally clamped. Increases the probability of switching to mode.

  In S61 shown in FIG. 17, the transfer unit 17 that has been holding the disk D in the transfer operation position shown in FIG. 9 is rotated clockwise toward the standby position shown in FIG. At this time, the roller shaft 111 of the transfer unit 17 is rotated in the same direction as when the disk D is carried inward of the housing 2 (Y2 direction). Therefore, the moving speed of the transfer unit 17 and the transfer speed by the transfer rollers 112 and 113 act in the opposite directions, and the transfer unit 17 is in the standby position without exerting a large force on the disk D in the Y1 direction or Y2 direction. Moved to.

  At this time, if the center hole Da of the disk D is normally clamped to the rotation drive unit 82, the disk D hardly moves, and the loading detection member 200 shown in FIG. The light shielding portion 203 remains in a state where it is removed from the detection element Fe for detecting completion of loading, and light from the light emitting element of the detection element Fe is received by the light receiving element. Continue (ON).

  On the contrary, when the disk D is not normally clamped to the rotation drive unit 82, even when the roller shaft 111 rotates in the same direction as the loading operation when the transfer unit 17 moves toward the standby position, The disk D moves slightly in the Y1-Y2 direction. Since the loading detection member 200 is urged clockwise, when the disk D moves, the light shielding portion 203 of the loading detection member 200 enters the detection element Fe, and the light from the light emitting element cannot be received by the light receiving element (OFF )

  That is, the amount of rotation of the loading detection member 200 from the ON state where the light shielding portion 203 of the loading detection member 200 is disengaged from the detection element Fe to the detection element Fe enters the OFF state is that the disk D is normally clamped. In other words, the amount of movement of the disk D in the Y1-Y2 direction when the transfer unit 17 rotates toward the standby position is set sufficiently shorter. The amount of rotation is set so as not to switch from the ON state to the OFF state if the disk D is normally clamped.

  In S62 of FIG. 17, while the transfer unit 17 is moving toward the standby position, it is monitored whether or not the detection element Fe continues to be ON. In S63, if the detection element Fe continues to be in the ON state even after a predetermined time has elapsed since the transfer unit 71 starts to rotate toward the standby position, and the clamp element is normal in S64. Complete confirmation that there is.

  Note that the predetermined time set in S63 means that the holding unit 106 and the transfer rollers 112 and 113 of the transfer unit 17 moving to the standby position are not detached from the outer peripheral edge of the disk D, and the holding unit 106 and the transfer roller 112. , 113 is set within a period in which the disk D is still being held.

If it is confirmed in S64 that the clamping is normally performed, in S65, the transfer unit 17 is continuously rotated to the standby position in the clockwise direction, and the rotation of the roller shaft 111 is continued. The transfer unit 17 is moved to the standby position. In the standby position, the clamping unit 106 and the transfer rollers 112 and 113 are disengaged from the outer peripheral edge of the disk D, and the transfer unit 17 is moved outward from the outer peripheral edge of the disk D being clamped.
Thereafter, the process proceeds to S66, and the disk drive mode is entered.

  If the detection element Fe is turned off even once within the predetermined time set in S63, the disk D is not normally clamped to the rotation drive unit 82 and the disk D is moved according to the operation of the moving unit 17. The possibility is very high. The predetermined time set in S63 is a period in which the clamping unit 106 and the transfer rollers 112 and 113 of the transfer unit 17 are not detached from the outer peripheral edge of the disk D. 9 is rotated counterclockwise toward the transfer operation position shown in FIG. At the same time, the roller shaft 111 is rotated in the same rotation direction as when the disk is unloaded. By this returning operation, the transfer unit 17 moves to the transfer standby position without causing the disk D to move greatly in the Y1-Y2 direction.

  In the subsequent clamp release operation shown in S68, the switching member 38 is moved in the Y2 direction by the first motor M1 of the first power transmission unit 12 shown in FIG. 1, and first, as shown in FIG. The clamp claws 86d of 82 are retracted into the convex portions 86b, and the clamp is released. Further, the lock switching member 42 shown in FIG. 1 is moved in the Y2 direction, the lock member 54 and the lock member 61 are moved in the X2 direction, the drive unit 14 is lowered, and the convex portion 86b of the rotary drive unit 82 is moved. Moves away from the disk D.

  In S69, the disc is ejected. In this discharge operation, the roller shaft 111 is driven by the third motor M3 to rotate the first transfer roller 112 and the second transfer roller 113 in a direction in which a carrying output in the Y1 direction is given to the disk, and further the second The motor M2 is started, the switching member 91 shown in FIGS. 6 and 7 is moved in the (d) direction, the transfer unit 17 is rotated in the clockwise direction, and returned to the standby position shown in FIG.

  When the disk D is ejected from the insertion slot 23, the detection members 251 and 252 shown in FIG. 11 return to the closest initial position, and the detection switches SW1 and SW2 are both turned on, the ejection operation is stopped. Alternatively, when the detection member 251 returns to the position indicated by (i) in FIG. 10 and the detection switch SW3 is turned from ON to OFF, the third motor M3 is stopped and a part of the disk D is enclosed. The discharging operation is stopped while being held in the body 2.

  In the clamp confirmation operation S60 shown in FIG. 17, it is possible to confirm whether or not the disk D is normally clamped only by monitoring the output of the detection element Fe when moving the moving unit 17 to the standby position. . In other words, as shown in FIG. 11, the disk device performs the clamping operation while holding the disk D by the transfer unit 17 moved to the transfer operation position. Therefore, after the clamping operation is completed, it is necessary to rotate the transfer unit 17 to the standby position and release the holding of the disk D by the transfer unit 17.

  In the clamp confirmation operation S60, it is confirmed whether or not the disk D is normally clamped using the operation period for releasing the above-described disk holding. Therefore, if the disk is clamped normally, the transfer unit 17 continuously moves toward the standby position until S65 shown in FIG. In this way, since the clamp confirmation operation can be performed using the period during which the transfer unit 17 moves to the standby position, it is not necessary to provide a new inspection period for the clamp confirmation, and the processing time can be shortened. .

(Disk drive mode)
When it is confirmed in S64 of FIG. 17 that the disk D is normally clamped to the rotary table 86, the holding claws 155, 156, and 157 shown in FIG. 10 are rotated to support at the selected position (a). The holding of the disk D by the body 21 is released.

  Thereafter, the first motor M1 of the first power transmission unit 12 shown in FIG. 1 is started, and the lock switching member 42 is further moved in the Y1 direction. At this time, the switching member 38 does not move, the drive slider 85 is not driven, and the drive unit 14 maintains the state moved to the intervention position. Then, the connecting rotation lever 43 is driven counterclockwise, and the lock switching member 42 is driven in the Y1 direction. At this time, the lock member 54 is moved in the X1 direction, and the lock member 61 shown in FIG. 2B is moved in the X1 direction.

  A restraint shaft 77 and a restraint shaft 78 provided in the unit support base 13 by a relief portion 56c of the lock control hole 56 provided in the lock member 54 and a relief portion 62c of the lock control hole 62 provided in the lock member 61. 78 is in a free state, and the unit support base 13 and the drive unit 14 supported by the unit support base 13 are elastically supported by the dampers 71, 72, and 73. Therefore, the disk D can be rotationally driven by the spindle motor Ms, and the reproducing operation and the recording operation can be performed by the optical head 83.
