<p>PURPOSE:To display the direction in which a tape starts to run by blinking a display lamp in directions of fast forwarding (FF)/rewinding (RW) and PLAY coincide with each other, but if the directions of FF/RW and PLAY differ from each other, display lamps of the respective directions are blinked or lighted on. CONSTITUTION:If the power supply is turned ON, a tape running direction detecting circuit 15 while playing detects the running direction; since there is no input from a detection circuit 16, switch circuits 14a, 14b outputs to lighten either display lamp 11a or 11b via diodes 13a or 13b to display the running. If an instruction for the operation of FF or RW is issued by the deck controller, an FF/REW action switch 17 turns ON, and a signal is transmitted to FF/REW tape running direction detecting circuit 16 to detect the running direction to the right-hand side or left-hand side direction. Thus obtained detection signal is transmitted to blinking circuit 12a, 12b and the switch circuits 14a, 14b, and blinking output signals are outputted from either the circuit 12a or the circuit 12b, to turn on in blinking either the running display lamp 11a or 11b.</p> |
