PURPOSE:To achieve mode switching with a light touch, by providing a lock pin for fast feed and rewinding to a rotating plate energized to a prescribed direction and bearing this rotating plate to a fast feed and a rewinding lever. CONSTITUTION:When a fast feed button 3 is depressed from a stop mode as shown in Figure, an operating pin 22 of a lever 7 contacts a mating plane 22' to slide a switch plate 38 to the left. A lock pin 28 on a rotating plate 24 passes through a nail 28' and a lock release pin 17 contacts a nail 17' to slide a lock release plate 32 to the right, a switch 45 turns on, a solenoid 47 locks a lock plate 35 for fast feed mode. Then, when a rewinding button 5 is depressed, a lock release pin 19, a release nail 19', a release projection 24' and the rotating plate 24 cooperate to release the lock pin 28 and the lever 7 is restored, an operating pin 23 contacts a mating plane 23', the switch plate 38 energizes the solenoid and a lock nail 29' and a pin 29 keep locking the plate 35. Thus, the switching of each mode can be made with a light touch. |
