Abstract

PURPOSE:To simplify a mechanism by switching pinch rollers by engaging a couple of gears, engaging with a pulley pinion all the time, with a rack body when channels are changed. CONSTITUTION:For channel switching, pushing a shifter to right, for example, guides a shaft 21 in the slanting groove 5' to rock a pinion lever 2 to this side. Then, the pinion 3'' of the 1st gear couple 3 engages with an internal gear rack 6' before a rack body 6. Since the large gear 3' of the 1st gear couple 3 engages with the pinion 1'' of a pulley pinion couple all the time, the turning of the pinion 3'' moves the rack body 6 to the left and a pawl 22 provided at the center lower part of the rack body 6 tilts a pinch roller pushing-up lever 7, provided to a fixed shaft 23 freely rotatably, to the left, thus changing pinch rollers over.
