<p>PURPOSE:To simplify constitution and improve an operational efficiency by controlling the rotation of a motor according to selected modes and setting each constitution material to the mode position through a cam mechanism controlled by the motor. CONSTITUTION:When switch S6 is closed to select a play mode, control pins 22 and 25 are displaced to dotted-line positions 22' and 25' by the rotation control of control motor M. Then, control lever 16 rotates in the clockwise direction to drive head substrate 3 to a prescribed forward position in the arrow A direction. Meanwhile, control lever 24 rotates in the counterclockwise direction to slide control plate 27 in the arrow B direction, and the connection between support arm 12 and cut part 31 of stand part 30 is released, so that support arm 12 rotates in the counterclockwise direction to compress pinchroller 10 to capstan 9, and the play mode position is set. When the play mode is switched to a stop mode from this position, the reverse operation is performed. Thus, operations can be facilitated by a simple constitution.</p> |
