PURPOSE:To minimize a kind of switches installed on a panel and to obtain multifunction by releasing a timer reproduction mode on conditions that a forward switch or a reverse one has been operated in the timer reproduction mode. CONSTITUTION:When the forward switch 5 and track number display switch 7 are all turned on, an AND gate 70 generates an output signal. When the reverse switch 6 and the track number display switch 7 are all turned on, an AND gate 72 generates the output signal. When the forward switch 5 or reverse switch 6 is turned on in the midst of reproducing a timer, an OR gate 74 produces a clear signal CLR. A counter part 76 executes addition and subtraction with outputs of the AND gates 70 and 72 and is reset by the signal CLR, whereby the timer reproduction is released. |
