ABSTRACT:
In an apparatus for recording and/or reproducing signals on an information carrier comprising a loading mechanism for loading the information carrier (21, 85), a drawer (10, 76) is provided, which is rectilinearly retractable and extensible between an opened and a closed position which carries a platform (24, 86). The drawer (10, 76) has in side walls (15, 16, 81), viewed in the inward direction, upwardly extending guiding grooves or slots (27, 82, 83) in which the platform (24, 86) is guided so as to be movable in the direction of height with respect to the drawer (10, 76) between an upper and a lower position. The platform (24, 86) is moved during a first part of the inward movement over the horizontally arranged surface (33a, 79a) of at least one positioning element (33, 79) and is held in the grooves or slots (27, 82, 83) at the level of the upper position and is then urged during a second part of the inward movement against at least one fixedly arranged upwardly directed stop (35, 101), then moves in the grooves or slots (27, 82, 83) down the stop (35, 101) in a direction substantially perpendicular to the supporting means (20, 102) for the information carrier to the lower position.
