<p>PURPOSE:To simplify a construction by controlling the rotation of an electric motor and permitting a continuous reproduction, dubbing and a remote control to stop temporarily. CONSTITUTION:When the button of the 1st recorder having a reproducting function is fixed on a action, a switch SW3 is turned on, and selects a dubbing side 13b. When the SW3 is turned on, a transistor Q 4 is turned on to drive 6 the electric motor 1, whereby reproduction or dubbing is carried out. When the button of the 2nd recorder having recording and reproducing functions is fixed on an action, a SW7 is turned on, and the SW13 selects the dubbing side 13b. When the SW7 is turned on, transistors Qs 8 and 10 are turned on to drive 12 the electric motor 2. Whenever a remote signal is received 31, a temporarily stop signal and a temporarily stop releasing signal are alternately outputted 33 to control the conduction of a transistor Q 50. With this constitution, when the SW 13 is at a continuous reproduction side 13a, the electric drive circuit 6 turns off an electric drive circuit 12, and vice versa. When the circuit 6 stops temporarily the circuit 12 through a remote control with the circuit 12 in an operable state, the circuit 12 can be turned off without affecting the drive action of the circuit 6.</p> |
