<p>PURPOSE:To switch power to a pinch roller or a reel board by means of a switching gear to be rotated in the same direction by shifting the selective switching of the pinch roller from the power switching time to the real board only by a main switch body. CONSTITUTION:A head base 30 is moved by the switching rotor driven by a motor to set up a mode. At that time, the main switching body 45 is driven by the switching rotor. When the head base 30 is positioned close to a stop position, a roller switching body 35 on the head base 30 is driven by the main switching body 45 and the pinch roller is selectively switched. After completing the switching, the main switching body 45 drives a mode switching body 36 for the base 30 on the way of advancement of the head base to a play mode position to switch a power transmission route from the real board to an idler rotor 14. In the constitution, mode switching is attained by the simple constitution and executed by a one-way rotating motor.</p> |
