PURPOSE:To avoid giving damage to a tape cassette, a magnetic tape draw-out means and a magnetic tape by giving the energizing force to the tape draw-out means in response to the go and return movement of said tape draw-out means between the 1st and 2nd positions. CONSTITUTION:A motor is revolved when a reproduction button is pressed in a pause mode shown in the figure, and a driving gear 160 and a rotor 142 are turned clockwise and counterclockwise respectively. At the same time, a cam 162 starts its clockwise revolutions. When the cam 162 keeps its revolutions up to a revolving angle 180 deg., a pressure pin 53 rubs and shifts on the cam surface to press-fix guide posts 23 and 27 to fixed members 184 and 185, respectively. In this case, the energizing force of a tension spring 152 turns a sectrial gear and an arm counterclockwise. Thus the load is reduced when a large load is generally needed for pressure-fixing of the posts 23 and 27 to the members 184 and 185. This reduces greatly the motor current. |
