The signals of the eject button switch 21 and the switch 24 for detecting complete ejection of the magazine are input to the tray forced ejection control means 19.

The normal operation of the CD autochanger device 1 will be described. When the magazine 3 containing a plurality of trays 5 is inserted from the insertion port 4, the magazine 3 is moved to a predetermined position by the magazine drive mechanism 7. Next, the gantry 11 is raised by the gantry drive mechanism 12 to a position where the tray 5 of the magazine 3 is pulled out. Then, the tray drive mechanism 13 causes one tray 5 to move to the magazine 3
And is stored in the gantry 11. After that, stand 1
1 descends, and when the lowest point is reached, the disc on the tray 5 is reproduced by the player unit 8.

When the reproduction by the player unit 8 is completed, the gantry 11 puts the tray 5 thereon, moves up to the pull-out position, returns the tray 5 to the magazine 3, and moves to the pull-out position in which the CD to be reproduced next is stored. Then, the tray drive mechanism 13 pulls out the tray 5 from the magazine 3 and stores it in the gantry 11. After that, the above-described operation is repeated, and the CDs stored in the magazine 3 are sequentially taken out and reproduced.

Next, in the above CD autochanger device 1, the operation of stopping the operation of the device 1 during the reproduction and ejecting the magazine 3 from the device will be described with reference to the flowchart of FIG. When ejecting the magazine 3, the eject button switch is pressed to turn it on in step S11. As a result, in step S12, the gantry 11 moves up to the tray pull-out position in order to return the tray 5 to the magazine 3. In step S13, it is checked whether the gantry 11 has reached the pull-out position, and when it reaches that position, the tray 5 is stored in the magazine 3 in step S14.

In step S15, it is checked whether or not the tray 5 is completely stored in the magazine 3, and if completed, the gantry 11 is lowered to the lowest point in step S16. In step S17, it is checked whether or not the lowering of the gantry is completed, and when it is completed, the operation of ejecting the magazine 3 from the inside of the casing 2 is performed in step S18. When the ejection of the magazine 3 is confirmed in step S19, this magazine ejection operation ends.

If an abnormality occurs such that the above operation is stopped midway, one of the loops from step S13, 15, 17, and 19 for returning to the original is repeated, and the process cannot proceed to the next step. At this time, the control device 14 detects that points A to D of each loop continue for a certain time or longer, determines that an abnormality has occurred, and stops all the mechanisms in the device. Further, the stoppage of all devices due to the occurrence of such an abnormality occurs not only during the above-described magazine ejection operation but also during other operations.

The recovery operation from such an abnormal stop state in the apparatus of this embodiment will be described with reference to the flowchart of FIG. When attempting a recovery operation, the operator performs an operation of pressing the eject button 4 for 5 seconds or more in step S21. The control device 14 detects this state and starts the following recovery operation. The operation start in step S21 may be automatically performed when the control device 14 detects that an abnormality has occurred at points A to D of each loop.

Next, in step S22, the magazine 3 is ejected to the outside of the casing 2 by the magazine drive mechanism 12. In step S23, the process waits until the ejection of the magazine 3 is completed. When the magazine 3 is ejected to the ejection position indicated by the chain double-dashed line in FIG. 2 and the ejection is completed, the switch 23 for detecting the ejection of the magazine is turned on, and the process proceeds to step S24. In step S24, the LED 22 is turned on and the eject button 21 is illuminated from the back side to notify the operator that the magazine 3 is ready to be pulled out from the casing 2.

In step S25, the process waits until the entire magazine 3 is completely withdrawn from the casing 2. When the operator pulls out the magazine 3 from the casing 2, the magazine 3
The switch 24 for detecting the complete discharge of is turned on, and the process proceeds to step S26. After the magazine 3 is pulled out, when the operator presses the eject button switch 21 in step S26, the process proceeds to step S27. Note that this step S26
Alternatively, instead of pressing the eject button switch 21, the process may automatically proceed to the next by detecting the complete ejection of the magazine 3.

In step S27, the tray forced ejection means 19 of the controller 14 operates the tray drive mechanism 13 of the gantry 11. As a result, when the tray 5 remains on the gantry 11, the tray 5 is discharged to the place where the magazine 3 was. At this time, since the magazine 3 is completely discharged from the casing 2, the tray 5 is discharged to the magazine storage portion without any trouble.

In step S28, the tray 5 is mounted on the mount 11
Waits until the sheet is discharged, and when the switch 25 for detecting the completion of tray discharge is turned on, the process proceeds to step S29. In step S29, the gantry driving mechanism 12 lowers the gantry 11 to the lowest point. In step S30, the process waits until the lowering of the gantry 11 is completed, and when the switch 26 for detecting the completion of the lowering of the gantry is turned on, the process proceeds to step S31 and LED
22 is turned off and the recovery operation is completed.

As described above, according to this embodiment,
When the CD autochanger device abnormally stops and performs a recovery operation, the magazine 3 is first ejected from the inside of the casing 2. After that, on condition that the magazine 3 is completely discharged from the casing 2, the rack 11 is moved to the tray 5
Is discharged to the place where the magazine 3 was. Therefore, even if the tray 5 on the pedestal 11 remains when the apparatus abnormally stops or the tray 5 is being returned from the pedestal 11 to the magazine 3, the tray 5 is discharged. Since the next recovery operation is started from, it is possible to return to the normal state safely and quickly without damaging the tray 5 or other devices.
