PURPOSE:To reduce the power consumption, by carrying out the switching between two modes just by applying a short and instantaneous electric power to a plunger solenoid each time. CONSTITUTION:In the STOP mode, an FWD slider 9 is returned to its returning position and a pinch roller 5 is detached from a capstan 4. At the same time, a toothless gear 16 is set to the nonintermeshing state opposite to a driving gear by a toothless part 16b, and a driving gear 14 of the capstan 4 rotating toward an arrow (l) by a motor driven by the application of the power supply runs idle. One projection of the gear 16 touches a stopper pin 37 of a trigger lever 25 to prevent the rotation of the gear 16 toward an arrow (b). Also in the STOP mode, a locking lever 26 is slightly turned toward an arrow C' by a roller 43, and an end 26a of the lever 26 is shifted at a position apart from a driving pin 35 of a solenoid 33, i.e., a position where no engagement is secured to the solenoid 33. |
