On the other hand, in the CD player main body, as shown in FIG. 14, a command signal sent from a remote control transmitter is received by a light receiving section 21 and supplied to a detection circuit 22 as an electrical signal. The detection circuit 22 demodulates the signal from the light receiving section 21 and extracts a serial data signal. A serial-to-parallel conversion circuit 24 is connected to the output of the detection circuit 22 via a waveform shaping circuit 23, and the waveform-shaped serial data signal is converted into a multiple-bit parallel data signal. The parallel data signal is supplied as a command code signal to a control circuit 25 consisting of a microprocessor. The control circuit 25 includes a RAM 26 for storing programs and a pickup 2.
a pick-up drive system 28 for driving 7;
A signal processing circuit 28 is connected thereto. The signal from the pickup 27 is supplied to the signal processing circuit 29 via the waveform shaping circuit 31.

Next, the processing operation of the received program by the control circuit 25 will be explained according to the flowchart shown in FIG. control circuit 25
Each time a signal is supplied from the serial-to-parallel conversion circuit 24, first, it is determined whether or not it is a stop code (step 151). If it is a stop code, an operation stop command is issued to the pickup drive system 28 (step 152), and it is determined whether a clear code has been supplied (step 152).
153). If it is a clear code, clear the program memory in RAM 26 (step 154),
Set step number S _Z equal to 1 (step
155). If it is not a clear code, it is determined whether it is a disk code (step 156). If it is a disc code, the disc code is temporarily held (step 157), and if it is not a disc code, it is determined whether it is a track code or not (step 158). If it is a track code, the track code is temporarily held (step 159),
If it is not a track code, it is determined whether it is a program code (step 160). If it is a program code, write the disk code and track code held in the program memory storage location specified by step number S _Z (step
161), 1 is added to the step number S _Z , and the calculated value is set as a new step number S _Z (step 162). If it is not program code, execute other processing. By repeating this operation, the program information transmitted from the remote control transmitter is transferred to RAM2.
