<p>PURPOSE:To simplify constitution and to reduce its size by switching reel shafts and by bringing a couple of pinch rollers into contact and to separate mutually by turns by utilizing the turning force of a motor. CONSTITUTION:An intermediate gear 10 engages with gears 4A and 4B of reel shafts 2A and 2B alternately according to the turning direction of a motor 14, and pinch rollers 17A and 17B come into contact and separate from each other alternately according to the turning direction of a changeover lever 21. IN this constitution, as a tape being reproduced comes to its end, the turning direction of a motor 14 is reversed and a rotary member 9 turns clockwise to turn the changeover lever 21 clockwise through a transmission member 35, a rotary lever 23, etc., thereby bringing the pinch roller 17B into contact with a capstan shaft 3B while separating the pinch roller 17A. The gear 10 engages with the gear 4B of the shaft 2B to change the running speeds of the tape. Thus, the constitution is simplified and reduced in size.</p> |
