Abstract
A cassette (1) for a record carrier (10) is provided with a sliding cover (2) for covering at least one opening (13, 14, 15, 16, 17, 18, 19, 20, 21) in the cassette housing (3), which cover has at least one plate-shaped flange (28) which extends parallel to a main wall (5) of the cassette housing (3), hold-down means (41) overlying its edge zone (31), which extends parallel to the direction of movement (22) of the sliding cover (2) and has a given length (L), in order to hold down the flange (28). Suitably, the hold-down means (41) comprise at least two hold-down members (50, 51) whose dimension (A) parallel to the direction of movement (22) of the sliding cover (2) is only a fraction of the length (L) of the edge zone (31) of the flange (28) of the sliding cover (2), over which edge zone said hold-down members engage.
