<p>PURPOSE:To simplify a rotating mechanism and to reduce its cost by composing a drive gear for rotating a feed reel base by which reciprocal rotation of a tape is transmitted. CONSTITUTION:By rotating a motor 12 clockwise, a fly wheel 7, movable member 8 and feed reel base 11 are rotated and the drive is turned into the fast forward operation, whereas by rotating the motor unticlockwise to make the reel base 11 reverse, the drive is then changed for the rewinding operation. A head substrate 2 is moved upward by actuating a solenoid 5, while a take-up reel base 1 is turned clockwise in accordance with the same clockwise rotation of the motor, and then a tape 14 is brought into contact with a magnetic head 3 so that the recording or reproducing operation takes place. Since the reciprocal rotation for a take is transmitted by a gear 11a of the reel base 11, a rotating mechanism is thus simplified with cost reduction.</p> |
