[0002]

2. Description of the Related Art Conventionally, when explaining a product or an exhibit at an exhibition or a museum, a magnetic tape player or the like is provided for each product or exhibit in order to make the description unattended. The description recorded on the magnetic tape was reproduced and output as sound from a speaker or the like.

Further, as one method for explaining products or exhibits in a predetermined order, an illumination light and a magnetic tape player are provided corresponding to each product or exhibit, and these illumination lights and magnetic tapes are provided. There is a method of controlling driving of the player by a timer. As another method, the description of each product or exhibit is sequentially recorded on one magnetic tape, and a predetermined signal sound is recorded after the description of each product or exhibit. Has been taken to switch the illumination light.

However, if the explanation is reproduced by using the magnetic tape player as described above, the head position of the explanation cannot be accessed immediately. Also,

On the basis of the comparison result, a drive switching device that selectively switches the on / off state of a plurality of switches connectable to an external device is proposed (Japanese Patent Application No. 3-70426).

With this, it is possible to control the driving of the external device in synchronization with the reproduction information of the optical disk. For example, when sequentially explaining a plurality of exhibits, these descriptions are recorded on the optical disk. By switching the illumination of each exhibit on the basis of the reproduction information, the explanation and illumination of each exhibit can be synchronized with each other, which does not give the viewer an unpleasant feeling.

On / off states of the relays RL1 to RL16 of the external device interface section 31 are switched based on the switching program pattern. Further, when the switching program pattern is not recorded in the subcode information of the reproduction information of the optical disc 1, the control circuit 323 determines each based on the switching pattern and the lead-in area index information stored in the memory 324 in advance. A switching program pattern is generated for each song and stored in the memory 324. Based on this, the relay RL is stored.
The on / off state of 1 to RL16 is switched.

Next, the operation of the embodiment having the above-mentioned structure will be described. In the following description, as described in the conventional example, a method of driving an illumination such as a laser beam while reproducing music will be described as an example. First, as described above, the optical disc player 2 and the drive switching device 3 are connected, and as shown in FIG. 3, the contact signals of the relays RL1 to RL16 of the external device interface unit 31 are the driving states of the illuminations L1 to L16. The relays RL1 to RL16 and the illuminations L1 to L16 are connected so as to be a signal for switching. For example, when the relays RL1 to RL16 are turned on, each relay R
Illumination L1 to L1 corresponding to L1 to RL16
Keep 6 illuminated.

On the other hand, a switching program pattern is recorded in advance in the sub-coding of the optical disc 1. In this switching program pattern, the on / off state of each of the relays RL1 to R116 is set corresponding to a predetermined track number in each music, and a switching instruction of the relay 321c of the information interface circuit 321 is set as a command.

As a result, when the drive switching device 3 is activated via the switch of the operation section 33 to reproduce the optical disk 1, the music reproduced by the disk drive section 21 and the reproduction signal processing section 22 is reproduced by the audio output section 23. Speaker
It is output from 233. At this time, the control circuit 323 determines the presence / absence of the switching program pattern during sub-coding, and when the switching program pattern is recorded, the illuminations L1 to L16 of the illuminations L1 to L16 are reproduced based on the switching program pattern while the music is being reproduced. The lighting state can be switched.

When an ordinary optical disk in which the switching program pattern is not recorded is reproduced, the control circuit 323 controls the index information and the switching pattern stored in the memory so as to be within the reproduction time of each song. A switching program pattern is automatically generated, and on / off states of the relays RL1 to RL16 are switched based on this. As a result, each illumination L
The lighting states of 1 to L16 are switched.

As described above, according to the present embodiment, it is not necessary to manually change the setting of the switching program pattern even when the optical disc 1 is exchanged, and it is possible to save the labor required in the prior art. Therefore, the operability can be significantly improved as compared with the conventional example. Further, since it can be used by being connected to the general-purpose optical disc player 2, the remote control function provided in the optical disc player 2 and the CPU control function such as random play or program play can also be used.

When controlling the driving of 17 or more illuminations, a plurality of drive switching devices 3 may be connected in series as shown in FIG. That is, a reproduction signal is directly input from the optical disk player 2 to the first drive switching device 3A, and a reproduction signal output from the optical link connector 321b of the first drive switching device 3A is output by the optical signal of the second drive switching device 3B. Input to the link connector 321a. further,
The reproduction signal output from the optical link connector 321b of the second drive switching device 3B is input to the optical link connector 321a of the third drive switching device 3C.

In this case, a command in the switching program pattern of the optical disk 1 switches the on / off state of the relay 321c in the information interface circuit 321 of each drive switching device 3A-3C. In other words, the control circuit 323 sets the mode of the above-mentioned command to “11
When it is "1", it is determined that the data in the pack is a switching program pattern. In addition, the mode is "11
When the item is "1", the value of the item is determined, when the item is "001", the relay 321c of the information interface circuit 321 is set to the on state, and when the item is "010", the relay 321c is turned off. . In addition, the control circuit 323
Starts storing the switching program pattern in the pack in the memory 324 when the value of the item is “011”,
When the item is "101", the storage of the switching program pattern in the memory 324 is completed. Further, if the item is “110”, the control circuit 323 turns on the relay 321c, and also activates the drive start command or relay 321c.
It waits in a state where it accepts only two types of commands to turn off. Further, the control circuit 323 starts the switching drive when the item of “111” is received, and then “010”.
The switching drive operation is interrupted when the item is received.

As a result, a plurality of drive switching devices 3A
Since an individual switching program pattern can be set for each of 3C to 3C, the lighting state of a number of illuminations can also be individually controlled.

In this embodiment, the on / off states of the relays RL1 to RL16 are switched according to the track number. However, the relays RL1 to RL16 may be switched so as to correspond to the absolute time T, and may be set according to the application. It is desirable to set.

Further, in the present embodiment, 16 relays RL1 to RL16 are provided in the external device interface section 31 to control the lighting of the illuminations L1 to L16, but the present invention is not limited to this. The number of relays can be increased or decreased as appropriate, and the driving of various devices other than illumination can be controlled. Also, means other than the relay can be used as an interface for controlling the driving of the external device. For example, a circuit that outputs a control signal for controlling driving of an external device based on a signal from the control circuit 323 may be provided.

Further, in the present embodiment, the switching program pattern is recorded on the optical disc 1 on which music is recorded as the main information, but the present invention is not limited to this, and the explanation of the exhibit as described in the conventional example is mainly recorded. The same effect is obtained even with the optical disc 1 recorded as information.

Furthermore, although the drive switching device 3 is constructed as a device independent of the optical disc player 2 in this embodiment, it is needless to say that the same effect can be obtained even if these are integrated.

[0039]

As described above, according to the first aspect of the present invention, the switching pattern is automatically generated only by reproducing the recorded information on the optical disk, and the information reproduction of the optical disk is performed based on the switching pattern. Since the drive of the external device is controlled in parallel with the above, it is possible to easily change the setting of the drive switching pattern of the external device, and it is possible to eliminate the conventional troublesomeness when changing the setting of the switching pattern.

According to the second aspect, switching pattern information is recorded for each optical disk, and when the information on the optical disk is reproduced, drive switching of the external device is performed based on the switching pattern information. It becomes unnecessary to change the setting of the switching pattern every time the optical disk is exchanged, unlike the conventional case.

Further, according to the third aspect, in addition to the above effect, even when a plurality of drive switching devices are connected, an individual switching pattern can be set for each drive switching device.
