ABSTRACT:
Spindle depress/brake apparatus in a disc dictation machine for depressing the record/playback spindle during a disc change cycle and for inhibiting rotational motion of the spindle after a new disc is loaded until the spindle properly engages a phasing slot in the disc. The apparatus includes a pivotally mounted bellcrank resiliently biased in a non-spindle depress direction. The bellcrank includes a Y-shaped first end engaging the spindle having a tooth for inhibiting rotation of the spindle and a second end which includes a cam surface, a mechanical latch and an adjustable stop. The spindle depress/brake apparatus is actuated by motion of the disc change loader carrier mechanism in the machine.
