ABSTRACT:
A cassette loading apparatus used in a recording and reproducing apparatus is provided which includes a cassette holder releasably holding a cassette; side wall members having formed therein first and second guide grooves in which guide pins planted on both side walls of the cassette holder are movably inserted so that the cassette holder is reciprocated between a first position where the cassette can be loaded into and unloaded from the cassette holder and a second position where recording and reproduction can be effected, the second guide grooves extending continuously from one end of the first guide grooves orthogonally thereto; a cassette holder drive unit including a gear and a rotatable arm for moving the cassette holder from the first position to the second position or vice versa; and a supplemental force imparting unit provided on at least one of the side wall members for imparting an urging torque when the guide pins are shifted from the second guide grooves to the first guide grooves, so as to retard the travel speed of the cassette holder before arrival of the cassette holder at the second position.
