Abstract
A photoelectric sensor is utilized for optically detecting the presence of a tape cassette in a loading commencement position to produce an electrical driving signal. Responsive to the driving signal, an electric loading motor is activated to cause a loading arm to swing from one angular position to another angular position. Rotary movement of the loading motor is translated into a pivotal swinging movement of the loading arm by a segmented linkage lever. The linkage lever carries a light beam interrupter piece which may cut off the light beam projected by the photoelectric sensor to enable the latter to generate the electrical driving signal. The linkage lever also carries an arm locking finger adapted to lock the loading arm in a loading completion position.
