Proceed to step 10.

In decision 110, it is determined whether or not the carry key 26b has been pressed, and if it is determined that the carry key 26b has not been pressed, the process directly advances to decision 115.
If it is determined that the carry key 26b has been pressed, the process proceeds to process 116, where 10 is stored in the built-in selection key memory KM, and the process proceeds to process 117. Note that if the total number of segmented program information recorded on the disc 1 used for reproduction exceeds 30, each time the carry key 26b is pressed, the number stored in the selection key memory KM is increased to 10.
Increased by increments. In process 117, selection key memory K
The content of the tens place stored in M, for example, 1.2.3 or 4, etc., is displayed as 10 in the track number display section 36a.
At the same time, a ``-'' sign is displayed on the digit display section 368'' and blinks on the digit display section 36a'' until the D/F select key 26a is pressed. Carry key 26 like this
When b is pressed, 10 or its multiple is temporarily stored in the selection key memory KM, and the 1O digit is displayed on the display section 36a° of the track number display section 36a.
By making the ``-'' sign flash on the display section 36a'', even when more than 20 segmented program information is recorded on the disk 1, the direct key 26
It is now possible to specify the track number corresponding to the segmented program information with a simple operation without increasing the number of items a, and it is also possible to visually indicate that the tens digit of the track number has been memorized. Next, the operation to be taken is suggested, thereby preventing the user from forgetting to press the direct key 26a.

Then, after going through process 117, decision 115
The process proceeds to decision 118 to determine whether or not the play key 24 has been pressed, and if it is determined that the play key 24 has been pressed, the process proceeds to decision 118 to determine whether play (playback state of program information from disk 1) is in progress. to judge. If it is determined that the game is not being played, the process proceeds to decision 119 (FIG. 4B), and if it is determined that the game is being played, the process proceeds to decision 120 (FIG. 4C). On the other hand, if it is determined in decision 115 that the play key 24 is not pressed, the process advances to decision 121,
Similar to decision 118, it is determined whether or not the play is in progress, and if it is determined that the play is in progress, decision 1

In decision 103 mentioned above, direct key 2
Process 107 to proceed when it is determined that 6a has been pressed
Now, add the number stored in the selection key memory KM in the process 116 described above (0 if the carry key 26b is not pressed) and the number of the pressed direct key 26a, and select the sum. It is stored in the key memory KM and proceeds to the digitilon 122, where it is determined whether or not it is in the programming mode. This judgment is made by programming mode indicator light PT.
This is done by detecting whether the programming mode indicator PL is on or off, and if the programming mode indicator light PL is off, the program is not in programming mode but in continuous playback mode or individual playback. It is determined that the mode is selected, and the process proceeds to process 123, where the target address is set to the beginning of the segmented program information represented by the trunk number stored in the selection key memory KM, and the process proceeds to process 124. In process 124, the track number stored in the selection key memory KM is cleared, and the process proceeds to process 125, where the play operation indicator light RL is turned on.

In the subsequent process 126, the muting control signal Cm is supplied to the program information processing section 8 to put the program information processing section 8 into a muting operation state, and the process 12
Proceed to step 7. In process 127, the reproduction address obtained from the decoder 7 is set in order to cause the reading position of the optical head 3 to reach the beginning of the segmented program information represented by the trunk number stored in the selection key memory KM, which is the target address set in process 123. Compare and calculate the playback address data D included in the data Q and the target address, and if the two address data do not match, send a control signal Cc to the reading position control unit 6 to make them match.
supply. As a result, the reading position control section 6 sends out a drive signal C8 to cause the optical head 3 to perform a forward or reverse continuous feeding operation that rapidly moves in the radial direction of the disk 1, and also sends out a drive signal C2. The tracking control means built into the optical head 3 is controlled to perform a track jump operation in the forward or reverse direction, and the optical head 3 performs a search that causes the read position to reach the target address. Make the user take the action in the operating state. After taking such a control state, the process proceeds to decision 128, where it is determined whether or not the playback address data D matches the target address. If it is determined that the playback address data D does not match the target address, the process proceeds to decision 128. Then, the process returns to process 127, and the above-described reading position control by the optical head 3 is performed again, and this is repeated.

If it is determined that the playback address data D matches the target address, the process proceeds to process 129, where the transmission of the muting control signal Cm that was being supplied to the program information processing section 8 is stopped, and the program information The muting state of the processing unit 8 is canceled and the process returns to process 103.

As a result, in the continuous playback mode or the individual playback mode, out of the plurality of segmented program information recorded on disk 1, the specified one can be played back according to the recording sequence order, or only the specified one can be played back. As a result, an audio signal A, which is a reproduction program information signal, is obtained at the output terminal 9.

On the other hand, in decision 122, programming

Therefore, if it is determined that the total programming number flag Fz is not the maximum, and therefore, if there is a possibility that further segmented program information to be provided for reproduction is specified, the process proceeds to process 131 and the total programming number flag Fz is set.
is incremented by 1 and the process proceeds to process 132, where the play operation indicator light RL is made to blink.

Next, the process proceeds to process 133, in which the content stored in the selection key memory KM in process 107, that is, the track number corresponding to the specified section program information, is stored in the programming memo IJPM.
It is stored in the location indicated by the total programming number flag Fz obtained in .

That is, the programming memory PM stores the playback order of selected pieces of program information from among the plurality of segmented program information recorded on the disc 1. The process then proceeds to process 134, clears the selected key memory KM, and returns to process 108. If it is determined in decision 130 that the total number of programming flags Fz is the maximum, the program proceeds to process 134 without going through processes 131-133, executes two consecutive processes 134, and returns to process 108.

Here, in process 132, the play operation indicator light RL
When the programming mode is selected by flashing the program information selection key 26
It is visually indicated that the trunk number corresponding to the segmented program information specified by the operation is stored in the selection key memory KM, and the next operation to be performed is suggested.

Decision 119 (see Fig. 4B
), similar to decision 122 mentioned above,
Determine whether or not you are in programming mode. As a result,
If it is determined that the program is in the programming mode, the process proceeds to decision 135, where it is determined whether the total number of programming flags Fz is O or not, that is, the trunk number corresponding to the designated segment program information is stored in the programming memory PM. In other words, it is determined whether the playback order of the designated segmented program information is stored in the programming memory PM. ~Here, the total number of programming flags Fz7! If it is determined that l<O, that is, if it is determined that the specified playback order of segmented program information is not stored in the programming memory PM, the process proceeds to process 136 to program the operating mode.・Switch from mode to continuous playback mode, extinguish the programming mode indicator PL, turn on the continuous playback mode indicator CL, and in the subsequent process 137, record the target address on the side closest to the playback start end of the disk 1. After entering the segmented program information, that is, the beginning of the segmented program information represented by the trunk number "1", the previous it process 125. Process 126.7'' Process 127. Executes Decision 128 and Process 129 and returns to Decision 103.

As a result, the plurality of segmented program information recorded on the disc 1 are reproduced from the first one in the continuous reproduction mode.

Further, if it is determined in decision 135 that the total number of programming flags Fz is not O, that is, if it is determined that at least one track number corresponding to the designated segmented program information is stored in the programming memory PM. Then, the program proceeds to process 138, in which the program performance flag Fp representing the playback order of the segmented program information is set to 1, and then the process proceeds to process 139. In process 139, the target address is set to the beginning of the segmented program information represented by the trunk number stored in the position indicated by the program performance flag Fp of the programming memory PM, and the process proceeds to process 125, whereupon the flow is as described above. move on.

This allows, under programming mode,
Pre-programming and programming of a designated one of the plurality of segmented program information recorded on disk 1.
Reproduction is performed according to the reproduction order stored in the memory PM.

On the other hand, in the above-mentioned decision 119, programming
If it is determined that the mode is not selected, that is, if it is determined that the mode is continuous playback mode or individual playback mode,
Proceed to decision 140 and trunk number display section 36a
It is determined whether the track number displayed is O, that is, whether the segmented program information has been specified, and if it is determined that the track number is 0, it means that the segmented program information has not yet been specified. If not, the process proceeds to process 137, and the flow proceeds in the same manner as described above.

Further, if it is determined in decision 140 that the trunk number is not O, that is, if classification program information is specified, the process proceeds to process 141 and the target address is set to the track number displayed in the track number display section 36a. After setting the segmented program information to be displayed at the beginning, the process proceeds to process 125, and the process proceeds in the same flow as in the case described above.

As a result, in the continuous playback mode or the individual playback mode, the first one or the specified one of the plurality of segmented program information recorded on the disc 1.
Alternatively, only the first one or the specified one is played.

In addition, decision 1 is executed when it is determined that the game is being played in the digital controllers 118 and 121 described above.
In step 20, it is determined whether the reproduction address data D included in the reproduction address data Q has changed to a new one, and if it is determined that the reproduction address data D has not changed, decision 103 is performed. Return to On the other hand, if it is determined that the playback address/data D has changed to a new one, the process proceeds to step 142, stores the new playback address/data D in the built-in memory, and returns to process 143. move on. In process 143, the track number is displayed on the trunk number display section 36a based on the new playback address data D.

Next, the process proceeds to decision 144, where it is determined whether or not the trunk number displayed on the track number display section 3 (ia) has changed.If it is determined that the track number has not changed, the process proceeds to decision 145, It is determined whether the reading position by the optical head 3 is located in the outermost recording area of the disc 1, that is, in the lead-out area, and if it is determined that it is not located in the lead-out area, decision 103 is made. Returning to step 1, program information reproduction from the disc 1 is continued, and if it is determined that the program information is located at the outermost recording section, the process advances to decision 146 and it is determined whether or not the continuous reproduction mode is selected.

Here, if it is determined that the continuous playback mode is selected, the process proceeds to process 147, in which a muting control signal Cm is supplied to the program information processing section 8 in order to put the program information processing section 8 into a muting state, and further, , proceeding to process 148, the reading position control unit 6. control signal Cc supplied to the motor control unit 11 and motor control signal C supplied to the motor control unit 11
s is stopped, control over the optical head 3 is ended, and the operation of reproducing program information from the disk 1 is ended, and the process returns to decision 103.

On the other hand, if it is determined in decision 144 that the trunk number has changed, or if it is determined in decision 146 that the continuous playback mode is not set, the process proceeds to decision 149, where it is determined whether or not the individual playback mode is set, and the individual playback mode is If it is determined that the mode is not the individual playback mode, the process 147 and 148 described above are executed sequentially to finish the playback operation of the program information from disk 1, and the process returns to decision 103. proceeds to decision 150 to determine if it is in programming mode. If it is determined that the program is not in the programming mode, the process returns to decision 103 to continue playing the program information from disk 1, and if it is determined that the program is in the programming mode, the process proceeds to process 151 to start the program. Increase the performance flag Fl) by 1 to make decision 152.

move on. In decision 152, it is determined whether the total programming number flag Fz is smaller than the program performance flag Fp, and if it is determined that the total programming number flag FZ is smaller than the program performance flag Fp, the process proceeds to process 147. Then, proceeding with the same flow as in the case described above, the operation of reproducing the program information from disk 1 is completed and the process returns to decision 103. If it is determined that the total number of programming flags Fz is not smaller than the program performance flag Fp, Process 13
Proceed to step 9 and proceed with the same flow as in the case described above to continue playing the specified piece of program information among the plurality of segmented program information recorded on the disk 1 according to the playback order prestored in the programming memory PM. .
