PURPOSE:To perform tape fast feeding according to the switch operating direction, by starting the electromagnetic hook of operation switching through the power supply or capacitance discharge and turning the scanning direction controlling rotating body for a half, in response to the operating switch. CONSTITUTION:When a scanning switch 1 is connected to a contact 13, a transistor 2 is conducted with the power supply voltage B and connected to a contact 12, through the discharge of a capacitor C1, to excite the run switching electromagnetic hook 3, and the control gear released for latch with the stopper 32 turns by one revolution. Thus, the gear prividing a crank pin 51 turns by a half revolution to switch the tape fast feed via a slide lever 6. With this constitution, the fast feed and rewinding according to the operating direction of the selector switch are made, allowing to switch the fast feed and rewinding with easy operation without malfunction. |
