<p>PURPOSE:To facilitate the extraction and storage of a cassette tape, by turning a pair of rolls in the opposite direction to each other to bring into press-contact them with both sides of the cassette tape. CONSTITUTION:A feeder motor 403 is attached within an elevator stage to turn cassette rolls 401 and 402. A spur gear 404 is adhered to the rotary shaft of the motor 403, and a spur gears 405, 410, 412 or 415 is provided between a spur gear 411 connected directly to the gear 404 and the roll 401 and a spur gear 416 connected directly to the roll 402. When the motor 403 turns counteclockwise, the rolls 401 and 402 turn clockwise and counterclockwise respectively. The same number of teeth is set between both gear groups to turn the rolls 401 and 402, and therefore the same speed of revolution is obtained between both rolls.</p> |
