<p>PURPOSE:To attain high reliability, by positioning the moving position of an operating plate switching the operating mode of a magnetic tape device with high accuracy, in moving to a plurality of positions. CONSTITUTION:A capstan motor 78 turns counterclockwise and turns a capstan 74 clockwise. A motor 50 starts turning counterclockwise. The rotation of the motor 50 is delivered to a cam 52 via a belt 44 and a gear 48, but even if the motor 50 starts turning, a sector gear 64 does not move immediately. When the rotary angle of a cam 52 exceeds 50 deg., since the 1st cam follower 62 inserted to one groove 54 of the cam 52 is shifted to the left, the gear 64 turns counterclockwise by taking a shaft 60 as a center. A gear 65 of a magnetic tape unloading means is turned, a guide post is moved and a magnetic tape is drawn out at the outside of a cassette.</p> |
