Next, the process proceeds to step 2, where the CPU 1 checks whether the enter button 52 (FIG. 6) has been pressed, and if not, proceeds to step 3, and the FROM / TO button 55 (the CPU 1 checks whether or not the key has been pressed, and if not pressed, advances to Step 4 and checks whether CPU No. 10 is pressed by the 10 key 50 (FIG. 6). If it is not pressed, it waits until it is pressed, and if it is pressed, the track number X is stored in the RAM 5 at step 5.

Next, the user proceeds to step 6 and checks with the CPU 1 whether the track number Y has been pressed by the 10 key 50 (FIG. 6), and if not pressed, proceeds to step 7 and the enter button 52 is pressed. The CPU 1 checks whether or not this has been pressed, and if not pressed returns to step 6, if pressed, stores E indicating that it was pressed in the RAM 5 in the step 8 and returns to step 2. That is, the series of operations of the steps 2 to 8 is the creation of a program by random track access, whereby one track digit X is set.

If track number Y is pressed in step 6, the track number Y is stored in RAM 5 in step 9. In step 10, the CPU 1 checks whether the ENTER button 52 has been pressed. If it is not pressed, waits until it is pressed, and if it is pressed, proceeds to step 8 described above and presses the ENTER button 52. Is stored in the RAM 5 and returns to step 2. That is, through the steps 6, 9, and 10 means that a track number X · Y of two digits is set in the creation of the program by the random track.

If the FROM / TO button 55 is pressed in step 3, F representing the beginning of the FROM / TO is stored in the RAM 5 in step 11. Next, the process proceeds to step 12, and the CPU 1 checks whether or not the track number R has been pressed by the 10 key 50, waits until it is pressed, and if so, the track number R is stored in the step 13 RAM ( Remember to 5).

Next, the user proceeds to step 14 and checks in the CPU 1 whether the track number S has been pressed with the 10 key 50, and if not, proceeds to step 15 and if the enter button 52 is pressed. Is checked in the CPU 1, and if it is not pressed, the process returns to step 14, and if it is pressed, the process proceeds to step 18, where T indicating the end of the FROM / TO is stored in the RAM 5. In other words, the series of operations of steps 11 to 18 means that a certain track number R of the first one digit as the starting point is designated when the program is created by continuous track access.

If track number S is pressed in step 14, the track number S is stored in RAM 5 in step 16. In step 17, the CPU 1 checks whether the ENTER button 52 has been pressed. If it is not pressed, waits for it to be pressed. If it is pressed, it goes to step 18 described above to indicate the end of FROM / TO. T is stored in the RAM 5. That is, through steps 14, 16, and 17 means that a track number R · S of the first two digits as the starting point in the program creation by the continuous track access is set.

Next, go to step 19 and check with the CPU 1 whether or not the track number P has been pressed by the 10 key 50. If not, wait until it is pressed. Remember to 5). Next, the user proceeds to step 21 and checks with the CPU 1 whether the track number Q has been pressed by the 10 key 50, and if not, proceeds to step 22 and whether the enter button 52 has been pressed or not. Is checked in the CPU 1, and if not pressed, the process returns to step 21. If it is pressed, the process proceeds to step 8 described above, and the RAM 5 stores E indicating that the enter button 52 is pressed, and the staff Return to 2. In other words, the series of operations of the steps 19 to 22 means that the last one-digit track number P which is the end point in the program creation by the continuous track access is set.

If the track number Q is pressed in step 21, the track number Q is stored in the RAM 5 in step 23. In step 24, the CPU 1 checks whether the ENTER button 52 has been pressed. If not, it waits until it is pressed, and if it is pressed, the process proceeds to step 8 described above. That is, through the steps 21, 23, and 24 means that the number P and Q of the last two-digit track serving as the end point is set in the program creation by the continuous track access.

The CPU 1 checks whether or not E has come from step 5, returns to step 4 if it does not come, and if it is, step 6 program-plays the track number C, or track number 5.

When the reproduction of the program of track number C ends, the process returns to step 2 again and the same operation is repeated for the track numbers 17 and 12. That is, the reproduction of the program by the random track access is sequentially performed.

Next, when F is detected in step 2, the track number at the time of the program by the continuous track access in step 7, that is, the track number 13 is set in the above example. Specifically, first, the corresponding 1 in 10 of track number 13 is set in step 7, and the CPU 1 checks whether or not T has arrived in step 8, and if not yet, returns to step 7 to return to track number 13 3 corresponding to the number of digits of 1 is set, whereby the track number 13 is finally set.

When T comes in step 8, the track number of the end point in the program by the continuous track access in step 9, that is, the track number 25 is set. Also in this case, first, 2 corresponding to 10 digits of track number 25 is set in step 9, and if CPU 10 checks whether or not E has arrived in step 10, and returns to step 9 if it is not yet, returns to track number 25 5 corresponding to 1's digit is set, thereby finally playing back the track number 13 program.

When the program reproduction of the track number A is finished, the process advances to step 12, where the next program included in the program by continuous track access is reproduced. That is, in the above example, the program of track number 12 is reproduced. In step 12, the signs of + and-indicate the direction of increase in FROM / TO when +, and the direction of decrease of FROM / TO when-. In step 13, A = B is checked by the CPU 1, and if not, the process returns to step 11 and repeats the above-described operation. And sequentially 13, 14, 15... Play the program of each track number, and if step A is B in step 13, that is, track number 25, go to step 14, where track number B, the last program in track number 25, is played back and step 2 is returned. .

Hereinafter, the track numbers 30, 45 and 1 are performed in the same manner as the track numbers 5, 17 and 12. When step 3 detects E, step 15 terminates execution of the series of programs.
