PURPOSE:To switch operations between a receiver and a reproducer with simple operation and structure in response to a program reservation signal of the receiver and the output from a flip flop which changes the stable state with a manual operation. CONSTITUTION:The reservation time of a receiver is stored in a random access memory 23 by a time adjusting circuit 23a according to the operation of a switch 17. At the reservation time, a signal on a line 24 and a signal on a line 22 from a counter 21 are compared with each other by a comparing circuit 25, and a flip-flop F2 is set to supply power to the receiver. When a cartridge is not loaded to a reproducer, the stable output of a flip-flop F3 is inverted by the operation of a control switch 18, and the receiver is operated even if it is not the reservation time. When a cartridge is loaded to he reproducer, the output of a line 2 becomes high-level, and the output from an NAND gate G2 becomes low-level, and the receiver is left inactive. |
