<p>PURPOSE:To perform both reproducing operation and fast-forward operation in one cartridge insertion slot by moving forth or back a head substrate so that a capstan for reproduction or fast-forward roller abuts on a pinch roller. CONSTITUTION:A head substrate 9 is provided with a head 11 and a capstan 12 for reproduction, and when the fast-forward operation is performed, a head 11 rotates counterclockwise around a fulcrum 10 of rotation together with the head 9 and the capstan 12 for reproduction is separated from a pinch roller 29. On the other hand, a fast-forward roller 31 is pressed against the pinch roller 29 to transmit the driving force of a motor 51. When the fast-forward operation is switched to the reproduction, a plunger 36 is fed with electricity for a short time to transmit the rotation of a motor 15 to a cam gear, the head substrate 9 rotates clockwise around a fulcrum 10 of rotation to release the fast-forward roller 31 and pinch roller 29 from press contacting, and the capstan 12 for reproduction is pressed against the pinch roller 29 to transmit the driving force of the motor 15.</p> |
