Further, when the disk 10 is unloaded by the conveying means 500 and the loading arm 510 rotates to the front side, the link plate 550 moves to the right side and the movable piece 611 protrudes to detect the unloading of the disk 10. When the switch 610 detects the insertion or unloading of the disk 10, it outputs a signal to that effect to the control circuit unit 600.

  The control circuit unit 600 is configured as a circuit configuration on a circuit board on which various electrical components are mounted, and controls the operation of the entire disk device 100. In addition, when the control circuit unit 600 recognizes that the operation of unloading the disk 10 has been completed, the control circuit unit 600 performs a temporary rotation process for temporarily rotating the turntable 222. Details of the temporary rotation process will be described later.

[Disk unit operation]
Next, the carry-out operation of the large-diameter disk 10B in the disk device 100 will be described.
FIG. 4 is a plan view showing an internal configuration of the disk device before unloading. FIG. 5 is a plan view showing the internal configuration of the disk device after the disk unloading is started. FIG. 6 is a plan view showing the internal configuration of the disk unloading completion position of the disk device.

First, as shown in FIG. 4, when the large-diameter disk 10B is inserted into the case body 110, the control circuit unit 600 recognizes an operation to carry out the large-diameter disk 10B, and then performs the first movement. The cam 420 is moved to the back side. When the link plate 550 is moved to the right side by the movement of the first moving cam 420, the arms 510, 530, 560, 570, and 580 are rotated to hold the outer edge of the large-diameter disk 10B. Thereafter, when the first moving cam 420 further moves to the back side, the pedestal part 210 moves to the bottom side, and the large-diameter disk 10B is detached from the turntable 222 by an unillustrated eject pin.
Thereafter, the large-diameter disk 10B moves to the front side as shown in FIG. 5 by the driving of the roller 511 of the loading arm 510 and the urging force of the eject arms 570 and 580.

  When shifting from the state shown in FIG. 5 to the state shown in FIG. 6, the guide arm 560 is moved forward (clockwise) by the urging force of the guide urging means 590 in conjunction with the rotation of the arms 510 and 530. The guide member 561 passes over the table mounting portion 222B. Thereafter, when the large-diameter disk 10B is further unloaded and moved to the unloading detection position, the movable piece 611 of the switch 610 protrudes, and the control circuit unit 600 detects that the large-diameter disk 10B has been unloaded. Here, the carry-out detection position is set to a position where the large-diameter disk 10B and the small-diameter disk 10A do not face the table rotation shaft portion 222A. Then, as shown in FIG. 6, the control circuit unit 600 immediately performs a temporary rotation process in which the turntable 222 is rotated in the counterclockwise direction indicated by the arrow Y1 for a predetermined time, for example, several seconds. That is, the turntable 222 is temporarily rotated in a direction in which the portion of the turntable 222 that overlaps the movement locus of the guide member 561 moves toward the carry-out direction.

Here, for example, when the guide member 561 rides on the anti-slip sheet 222D of the turntable 222 as shown in FIG. 3 due to the inclination of the parts, a frictional force is generated between the guide member 561 and the anti-slip sheet 222D. Thus, the guide arm 560 may not return to the carry-in standby position shown in FIG. 1 despite the biasing of the guide biasing means 590.
Even in such a case, the guide arm 560 returns to the loading standby position by the biasing of the guide biasing means 590 by forcibly rotating the turntable 222 counterclockwise by the temporary rotation process.

[Effect of disk unit]
According to the above disk device 100, the following effects can be expected.
(1) The disk device 100 temporarily rotates the turntable 222 after the transporting operation 500 finishes the unloading operation of the disk 10.
For this reason, even if the guide member 561 rides on the anti-slip sheet 222D and the guide arm 560 does not return to the loading standby position in spite of the urging of the guide urging means 590, the guide arm 560 is temporarily moved by the rotation process. It can be returned to the loading standby position. Further, the disk 10 is only rotated temporarily without increasing the biasing force in the carry-out direction by the guide biasing means 590 and without providing the eject lever guide roller as in the prior art. There is no effect on the loading of the machine, and the configuration is not complicated. Furthermore, the distance between the turntable 222 and the guide member 561 in the normal state can be set small, and the disk device 100 can be easily reduced in thickness.

  (2) Since the temporary rotation process is performed immediately after the end of the unloading operation is detected by the disk device 100, the guide arm 560 can be reliably returned to the insertion standby position before the disk 10 is inserted by the user.

  (3) The carry-out detection position that is a reference for starting the temporary rotation process is set to a position where the large-diameter disk 10B and the small-diameter disk 10A do not face the table rotation shaft portion 222A. Therefore, for example, even if the user pulls the large-diameter disk 10B obliquely upward, even if the leading end side of the guide arm 560 is bent toward the turntable 222 side, the table rotating shaft portion 222A and the recording surface of the disk 10 11 is not in contact with the recording surface 11, and the recording surface 11 can be prevented from being damaged.

  (4) During the temporary rotation process, the turntable 222 is rotated in the direction in which the portion of the turntable 222 that overlaps the movement locus of the guide member 561 moves toward the unloading direction, so the guide arm 560 is reliably unloaded. It can be rotated in the direction and returned to the insertion standby position.

[Other Embodiments]
Note that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.

That is, an extraction detection unit that detects a state in which the disk 10 has been extracted from the case body 110 by the user after the carry-out operation is completed may be provided, and when the extraction is detected, the temporary rotation process described above may be performed immediately. .
Further, an insertion detection means for detecting a state in which the disk 10 is inserted into the case body 110 by the user before starting the carry-in operation may be provided, and the temporary rotation process may be immediately performed when the insertion is detected. .

Then, it is possible to provide riding detection means for detecting a state in which the guide arm 560 rides on the turntable 222 after completion of the conveying operation, and when the riding is detected, temporary rotation processing may be performed immediately. According to such a configuration, the processing load can be reduced.
Further, in the above embodiment, the turntable 222 may be temporarily rotated clockwise in the temporary rotation process. That is, the turntable 222 may be temporarily rotated in a direction in which a portion of the turntable 222 that overlaps the movement locus of the guide member 561 moves toward the carry-in direction. According to such a configuration, the guide urging means 590 is applied by rotating the turntable 222 clockwise to temporarily reduce the frictional force between the turntable 222 and the guide arm 560. The guide arm 560 can be returned to the loading standby position by the force.
Moreover, as a guide means of this invention, you may apply the structure which the whole can slide in the front-back direction instead of the guide arm 560 rotated centering on one end side.

Furthermore, the present invention may be applied to a disk device that processes only the small-diameter disk 10A or the large-diameter disk 10B, or a disk having another diameter.
In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.

[Effects of Embodiment]
As described above, the disc device 100 temporarily rotates the turntable 222 after the transporting operation 500 finishes carrying out the disc 10. For this reason, even if the guide member 561 rides on the anti-slip sheet 222D and the guide arm 560 does not return to the loading standby position, the guide arm 560 can be returned to the loading standby position by temporary rotation processing. Further, the disk 10 is only rotated temporarily without increasing the biasing force in the carry-out direction by the guide biasing means 590 and without providing the eject lever guide roller as in the prior art. There is no effect on the loading of the machine, and the configuration is not complicated. Furthermore, the distance between the turntable 222 and the guide member 561 in the normal state can be set small, and the disk device 100 can be easily reduced in thickness.
