Magnetic-tape cassette with a latching cover plate

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.
