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.

Abstract: A gear mechanism (1) is selectively reversible between two end positions and which comprises a driving gear member (3), which can alternately be driven in opposite driving directions (19, 20) and a driving member (5) which can be driven by said driving gear member, one gear member (3) being partly toothed to form a toothed portion (8) which is bounded by two end faces (6, 7). The gear members can be brought into and out of mesh with each other. For bringing the two gear members (3, 5) into mesh with each other in at least one driving direction (19, 20) of the relevant gear member (3) said members carry a pair of actuating stops (34, 35, 43, 44) which correspond to the relevant driving direction, which are axially offset relative to the teeth (8, 9), and which each comprise a stop surface (36, 37, 45, 46) whose geometry is in conformity with that of a tooth-flank surface (38, 39, 47, 48).

Abstract: A recording and/or reproducing apparatus (1) for a magnetic tape (3) that can be drawn out of a cassette (2) introduced into the apparatus is provided for wrapping the magnetic tape around a drum-shaped scanning device (15) of the apparatus with a tape guide device (29), which has at least one tape guide (32,33) which is displaceable by means of a displacement device (30) between a rest position and an operating position and which in its operating position is positioned by means of a positioning device (68) arranged on a displaceable support (70), while it keeps the magnetic tape (3) wrapped around the scanning device (15). For adjusting the tape tension when the magnetic tape (3) wrapped around the scanning device (15) is driven, the apparatus (1) is provided with a tape tension adjustment device (12) comprising a tape tension indicator.
