The program information instructed is written in an arbitrary program storage area, and the program information written in the arbitrary program storage area is read out and transmitted according to a transfer instruction, so that an information recording medium such as a disc is exchanged in an information recording medium reproducing apparatus. When the main body is set, the program information corresponding to the set information recording medium can be transferred to the program memory by a simple operation of the remote control transmission device without having to input a new program. Also, if the operation mode in the normal mode of the remote control transmission device of the conventional information recording medium reproducing device is the same, the program can be stepped every time the information recording medium is set without modifying the device main body by using the remote control transmission device of the present invention. A desired program can be reproduced without setting the unit. Further, since the remote control transmission device is provided with a battery as a power source, there is no need to provide a backup device in particular, and the configuration is merely an addition of a memory or the like.
Further, even when the main body is performing the reproducing operation, the program information can be input to the program memory in the remote control transmitting apparatus without stopping the operation.
