Next, the operation of the optical disc changer 10 to which the present invention is applied will be described with reference to FIG. FIG.
5 is a flowchart for explaining a disk exchange process performed during reproduction of a disk in the optical disk changer 10.

First, a predetermined disc is mounted on a playback device (not shown) provided in the optical disc changer 10.
The microcomputer 106 performs the above-described disc reproduction processing in response to a reproduction instruction by a key operation of the reproduction key 10d.

During the reproduction process, the microcomputer 1
06 monitors whether there is an instruction to open the disk exchange door 10a by a key operation of the disk exchange door opening / closing key 10c (step S11), and when there is an instruction to open the disk exchange door 10a (step S11). Yes), a control signal to open the disk exchange door 10a is output to the disk exchange door opening / closing control motor driver 109, and the disk exchange door 10a is opened.

Next, the microcomputer 106
It is determined whether or not there is an instruction to rotate the rotary tray 101 by operating the rotary tray operation dial 10f (step S12). If there is no instruction to rotate the rotary tray 101 (step S12; No), step S1 is performed.
Then, it is determined whether or not there is an instruction to close the disk exchange door 10a by operating the disk exchange door open / close key 10c.

In step S12, when there is a rotation instruction of the rotary tray 101 (step S12; Yes), the microcomputer 106 sends a signal for controlling the rotation of the rotary tray 101 in accordance with the rotation instruction to the rotary tray control motor driver 110. To rotate the rotary tray 101 (step S
13).

Next, the microcomputer 106
Based on the output signals from the first sensor 104a to the third sensor 104c, the slot position of the storage slot of the playing disk after the rotation of the rotary tray 101 is calculated, and the calculated slot position and the loading / unloading position are determined. It is determined whether they match (step S14).

In step S14, if the calculated slot position of the storage slot of the currently playing disk does not match the loading / unloading position (step S14; No), the microcomputer 106 operates by operating the disk replacement door opening / closing key 10c. It is determined whether there is an instruction to close the disk replacement door 10a (step S15).

In step S15, when there is no instruction signal to close the disc replacement door 10a (step S15; No), the microcomputer 106 proceeds to step S12 to determine whether there is an instruction to rotate the rotary tray 101. If the determination is continued and there is an instruction to close the disk replacement door 10a (step S15; Yes),
A control signal for closing the disc replacement door 10a is output to the disc replacement door opening / closing control motor driver 109, and the disc replacement process performed during the reproduction of the disc ends.

Returning to step S14, the description will be continued. In step S14, when the slot position of the storage slot of the disc being reproduced matches the loading / unloading position (step S14; Yes), the microcomputer 106 sets a timer to a preset predetermined time (step S16). Then, the process waits until it is determined that the rotary tray 101 has stopped (step S17).

In step S17, if the microcomputer 106 determines that the set timer has timed out and the rotary tray 101 has stopped (step S17; Yes), the microcomputer 106 issues an instruction to raise the disk discharge rod 116b to drive the disk discharge rod. Control driver 116
(Step S18).

Next, the microcomputer 106
It is determined whether or not there is an instruction to rotate the rotary tray 101 by operating the rotary tray operation dial 10f (step S19). If there is an instruction to rotate the rotary tray 101 (step S19; Yes), the disc ejection rod 116b is lowered. Is output to the disk ejection rod drive control driver 116 (step S20), and the process returns to step S13.

In step S19, when there is no instruction to rotate the rotary tray 101 (step S19; N
o), the microcomputer 106 operates the disk exchange door 10a by operating the disk exchange door open / close key 10c.
It is determined whether or not there is an instruction to close (Step S
21).

In step S21, when there is no instruction signal to close the disk replacement door 10a (step S21; No), the microcomputer 106 proceeds to step S19 to determine whether there is an instruction to rotate the rotary tray 101. Continue the judgment.

In step S21, when there is an instruction to close the disk replacement door 10a (step S21;
Yes), the microcomputer 106 outputs an instruction to lower the disk discharge rod 116b to the disk discharge rod drive control driver 116 (step S2).
2) A control signal for closing the disk replacement door 10a is output to the disk replacement door opening / closing control motor driver 109, and the disk replacement process performed during disk playback is terminated.

As described above, according to the optical disc changer 10 of the present embodiment, when the disc replacement door 10a is opened during the reproduction process of a predetermined disc,
The microcomputer 106 rotates the rotary tray 101 in response to a rotation instruction of the rotary tray 101 by operating the rotary tray operation dial 10f, and monitors whether the storage slot of the disc being played is at the loading / unloading position. Here, when the storage slot is at the loading / discharging position, the disk ejection rod 11 waits for the time until the rotary tray 101 stops completely.
6b to drive the disc ejection rod 116 over its slot.
b is projected.

Therefore, during reproduction of a predetermined disc, if the storage slot of the disc being reproduced is at the loading / unloading position,
The user can easily confirm that the slot at the loading / unloading position is the storage slot of the disc being reproduced. Therefore, another disk is not erroneously loaded onto the storage slot of the disk being reproduced, and the optical disk changer 10 can avoid a disk loading error.

The present invention is not limited to the contents of the above embodiment, and can be appropriately changed without departing from the gist of the present invention. For example, in the present embodiment, a CD is assumed as a disc to be loaded into the optical disc changer 10, but the present invention is not limited to this.
VD, CD-R (CD-Recordable), or CD-RW
(CD-ReWritable) and so on.

The number of disks that can be stored in the optical disk changer 10 is not limited to 200,
Rotary tray 101 such as 300 sheets or 400 sheets
And various settings can be made in accordance with the slot arrangement intervals.

Further, a disk discharge rod and a disk discharge rod drive unit for independently driving the disk discharge rods may be provided at all the slot positions facing the frontage of the disk exchange door 10a. For example, when 20 slots face the frontage of the disc replacement door 10a, 20 disc ejection rods are provided at the slot positions of these opposed slots, and the disc ejections that drive the 20 disc ejection rods independently are provided. A rod drive is provided.

In this case, when the disc exchange door 10a is opened during the reproduction process of the predetermined disc and the rotary tray 101 is rotated in response to an instruction signal by operating the rotary tray operation dial 10f, the microcomputer 106 starts the disc being reproduced. It is monitored whether or not the storage slot is located at the slot position facing the frontage of the disk exchange door 10a. When the storage slot of the disk being played is located at the slot position facing the frontage of the disk exchange door 10a, the microcomputer 106 waits for a predetermined time to elapse, and issues a control signal for driving the disk ejection rod at that slot position. Output to the disk ejection rod drive.

As a result, if the storage slot of the currently playing disk is located at any of the 20 slot positions facing the frontage of the disk exchange door 10a, not only at the loading / unloading position, the disk ejection rod at that slot position will be described. Only drives and the disc ejection rod protrudes into the storage slot of the playing disk, so that even if the slot is not at the loading / unloading position, the user can easily confirm that the slot is the storage slot of the playing disk. It can be confirmed.

Further, as shown in the present embodiment, the disk discharge rod 116b may be driven in conjunction with the operation of the disk replacement door 10a without providing the disk discharge rod driving section 116a.

In this case, when the disk exchange door open / close key 10c is first pressed, the disk exchange door 10a is opened for a predetermined width, and thereafter, the disk exchange door open / close key 10c (or a separately provided disk) is opened again. When the eject key is pressed, the disc exchange door 10a is opened more widely, and the disc eject bar 116b operates in conjunction with the operation of the disc exchange door 10a at this time.

As a result, since it is not necessary to provide the disk discharge rod driving section 116a for driving the disk discharge rod 116b, the configuration of the optical disk changer 10 can be simplified.

Further, an LED (Light Emitting Diode) is provided at the loading / discharging position indicated by reference numeral A1 in the drawing.
