Title: Tape pullout device
Inventor: UEDA MASASHI
IPC: G11B15/665
Filed: 1988-04-01
Abstract: PURPOSE:To simplify constitution and to make the position precision of a tape pullout pin accurate by fitting an elastic member to an arm driving means. CONSTITUTION:When a mode cam 7 is rotated clockwise at the time of pulling out a tape, a driving gear 4 rotates counterclockwise through gears 6 and 5, a driving gear spring 3 also rotates counterclockwise, a driving pin 1a is pressed by the spring 3 and a rotating arm 1 turns clockwise. The tape is pulled out in the direction of a cylinder 8 by pins 1b and 1c, and the tape is sandwiched by a capstan 11 and a pinch roller 2a. When the rotating angle of the gear 4 is made larger than the pullout stroke of the arm 1, and when the arm 1 is abutted on a stopper 9, pressure, which has resistance even if the spring 3 is bent and pressure from the tape presses on the pins 1b and 1c, is given to the arm 1. At the time of storage, the spring 3 deforms, and the arm 1 is pressed on the guide hole 10b of a chassis 10 with constant pressure, and therefore positioning is attained.
