Abstract

PURPOSE:To attain multi-functional timer operation with simple and low cost constitution by setting a stop period of operation during the operation of the device and stopping the operation after a set time is elapsed. CONSTITUTION:A prescribed time is counted by being operated during recording or reproduction and the operation is stopped together with the end of count. When a timer 20, e.g., is not operated, the recording/reproduction/stop operation is selected by a mode discrimination circuit 39 in response to the output state of AND gates 30, 32, 34. When a timer switch 11 is turned on, a FF4 19 gives 'H' level to an output Q and the output Q goes to 'L', then AND gates 31, 33, 35 are selected. The operating mode of the timer is set by operating the operation switch in such a way and the time starting the operation is set by the timer switch, then plural timer operations are applied by simple operation.
