<p>PURPOSE:To reduce the number of parts, to make a device light, and to reduce its cost by constituting so that a pressing body of the first arm presses or releases the second arm by a master gear which is turned by a rotation of the first motor, and the first or the second idler is driven to a prescribed mode by responding to the second motor. CONSTITUTION:In case a stop state is set to a rewiding state that a supply reel base 10 rotates at a high speed, by depressing a rewiding mode switch, a master gear 8 tunrns a little by a motive power of the first motor, and the first pin 14 provided on the first arm 7 traces on the first cam 15 provided on the master gear 8, but a pressing body of the first arm 7 uses the second motor jointly and controls it, and rotates at a high speed the first idler 1 and the second idler 4 in the direction for making them contact by pressing to the supply reel base 10. A rotating force of a pulley 21 which is made to contact by pressing to a rubber part 5 of the second idler 4 is transferred to the rubber part 5, the second idler 4 is supported by a spring 26, the supply reel base 10 is rotated by a small reduction ratio, and a rewinding state is executed.</p> |
