Abstract
A tape withdrawing member drive system forming a part of a loading mechanism for withdrawing a tape from a cassette for movement along a predetermined path of travel including gears driven from a motor through a rotation transmitting device, connecting linkages each including a plurality of joints supported at one end thereof by an end surface of one of the gears and engaging at the joint at the other end thereof one of tape withdrawing members. The system further includes the features that guide grooves for guiding the joints of the linkages and the joints at the other end and extending to the other end surface of the gears include arcuate groove sections concentric with the center of rotation of the gears and arcuate groove sections of radii equal to the length of the second link of each linkages, and that one of the gears is formed on a surface thereof opposite the surface at which the guide groove is formed with a cam groove for manipulating another mechanism and a cam groove for actuating a multiple contact slide switch.
