<p>Loading completion of small and large diameter disks is mechanically controlled to provide a mechanical control of a clamping operation and the like. An elongated hole of a third arm with a pin engageable with an elongated hole formed in a chassis couples with a pin mounted on a second arm. As a large diameter disk is loaded, the motion of the second arm is transmitted via the third arm to a slider. As a small diameter disk is loaded, the small diameter disk pushes a pin mounted on the third arm to rotate the third arm. The motion of the third arm is transmitted to the slider. The motion of the slider activates a power transmission mechanism which transmits power of the loading motor to a disk clamping mechanism and a driving mechanism for driving a loading roller supporting lever.</p> |
