DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention controls a plurality of disk devices (hereinafter referred to as "disk players") for selectively reproducing a plurality of different disks, respectively, by a single compatible controller. About things.

[0002]

2. Description of the Related Art In order to control a plurality of disc players for selectively reproducing a plurality of different discs, a dedicated control device is used for each disc, or a different disc player for controlling each disc player is used. It was controlled by various kinds of control signals.

[0003]

There is already a first disc player for selectively reproducing a plurality of discs and a control device for controlling the first disc player. Thereafter, a plurality of discs different from the disc player are selectively selected. When the second disk player for reproducing the data is developed, the number of disks is different, so that the control cannot be performed by the control device. The present invention is to provide means for solving this.

[0004]

Therefore, in the disk player of the present invention, a control device having at least an operation device and a communication device, and a control device via the communication device of the control device,
A first disk player having a reproducing means for selecting and reproducing a plurality of disks of the disk number of which the disk number is instructed to be reproduced by the operation means, and being replaced by the first disk player and controlled by the control device. When the second disk player receives from the communication means an instruction to play a disk that exceeds the range of selectable disk numbers, the second disk player has a smaller number of disks than the first disk player. And a control device for transmitting a control signal without a disk to the first disk player from the disk number instructed to be reproduced by the operation device by the control signal without the disk from the transmission device. Until the disc playback instruction is sent to the communication means up to It is obtained by, characterized in that a reproduction instruction of the disk.

[0005]

Therefore, even if a disk player with a small number of disks that can be stored is connected to a control device for controlling a disk player with a large number of disks that can be stored, control can be performed in the same manner as a disk player with a large number of disks that can be stored. .

[0006]

FIG. 1 is a connection diagram of a first disk player 1 and a control device 2. In the magazine case 6 for accommodating 10 disks, numbers 1 to 10 are assigned to the respective disks according to the locations where the magazines are accommodated. Control device 2
Is provided with a display 7, an operation button 8 for instructing reproduction and stop of the disk, and an operation button 9 for switching the disk.

The control device 2 includes a control line 5 for notifying the first disk player 1 that control is started, and a serial communication control line 4 for transmitting a control command to the first disk player 1 by the control device 2. And a serial communication control line 3 for transmitting a signal indicating the state of the first disk player 1 from the first disk player 1 to the control device 2.

FIG. 2 is a connection diagram of the second disk player 10 and the control device 2. Second disc player 10
Accommodates a magazine case 11 for accommodating five disks, and numbers 1 to 5 are assigned to each disk according to the location where the magazine case 11 is accommodated.

FIG. 4 is a diagram for explaining the processing of the first disk player device 1 and the second disk player device 10 when the control line 5 is turned on. In the disk player, the control line 5 is turned on. Then, the presence / absence of the magazine case 6 is transmitted via the serial communication control line 4, and then a communication start trigger signal for permitting the transmission of the serial communication control line 4 is transmitted via the serial communication control line 3.

FIG. 5 is a diagram for explaining a processing procedure when the operation button 8 of the control device 2 is pressed. Hereinafter, whether the control device 2 controls the first disc player 1 will be described with reference to FIG. When the operation button 8 of the control device 2 is pressed, the first disc player 1 is notified that the control line 5 is turned on and communication control is started. Next, it waits until the first disc player 1 transmits the presence or absence of the magazine case 6, and after receiving the transmission, waits until there is a communication start trigger. After receiving the communication start trigger signal, the magazine case 6 is removed. If so, this is displayed on the display 7 and the process is terminated. If the magazine case 6 is present, a control command to start reproduction is transmitted to the first disk player 1 via the communication means. After the first disc player 1 starts playing, the display information of the disc number and track number sequentially transmitted from the first disc player 1 is displayed on the display 7 unless the operation button 8 or the operation button 9 is pressed. I do.

When it is received that there is no disc with the corresponding number during the reproduction of the disc, the same operation as when the operation button 9 described below is pressed is performed. After starting playback,
When the operation button 8 of the control device 2 is pressed, a stop control command is transmitted to the first disc player 1 via the communication means, the display 7 is turned off, and the process ends.

When the operation button 9 of the control device 2 is pressed,
If the first disk player 1 is playing the tenth disk at the time of pressing, the control command for switching to the first disk if the first disk player 1 is playing the disk, or to the disk with the number plus one being played otherwise is sent to the communication means. To the first disc player 1 via the PC, and the display on the display 7 is also switched.

FIG. 3 is a diagram for explaining the processing when the second disk player 10 receives a control command for switching the disk number from the control device 2 via the serial communication control line 4. The second disk player 10 transmits that there is no disk with the corresponding number when disks 6 to 10 are specified. As described above, the control device 2 controls the first disc player 1 and the second disc player 1
0 can be controlled by either of them.

[0014]

According to the disk player of the present invention, it is possible to control the disk players having different numbers of disks that can be stored by the common control device.
