摘要： A device having a pivotal cover, such as a magnetic tape cassette, for covering one or more front openings between the front edges of two major walls which extend generally parallel away from the opening. The cover has flanges by which it is connected at the sides of the device, through a pivot pin and a straight slot, on the pivot axis, and another pin which engages a circular segment slot. The circular segment slot has a recessed portion which the other pin engages when the cover is closed. The cover must be moved in a direction away from both major walls, to an unlatched position, before it can be pivoted to an open position adjacent one or the other of the major walls.

摘要： A magnetic-tape cassette has a front opening (7) which when the cassette is not in use is covered by a pivotal front cover (20) and a sliding plate (9) which is situated on the outside of the cassette housing (1) adjacent the bottom wall (2) thereof. In the closed position the sliding plate covers the front opening (7) at the bottom and a part of the magnetic tape (18a) which extends across said opening. The top wall (3) of the housing is imperforate and is contiguous with the front cover in the closed position of the cover. In the closed position the sliding plate (9) extends from the front of the cassette housing (1) beyond openings (4) in the bottom wall (2) to cover these openings. The sliding plate is formed with two apertures (15) which expose the openings (4) in the open position of the sliding plate (9). In the closed position the sliding plate (9) is latched by means of at least one latching member (27) which comprises a latching portion (29) and an actuating portion (30), the latter projecting into a slot or groove (32) in the sliding plate (9) near the rear end of the slot or groove when this plate (9) is in the closed position.

摘要： 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.
