ABSTRACT:
A magnetic tape recording apparatus comprises at least one tape-guide device (18, 18') which is movable between a rest position and an operating position and, for moving said device, a drive member (26, 26') which is coupled to a supporting member (19, 19') of the tape-guide device via a disengageable coupling (27, 27'). The drive member (26, 26') and the supporting member (19, 19') are tensioned relative to each other by means of a spring (45, 45') which acts in the direction of movement, the spring urging the coupling abutments (39, 39', 40, 40', 41, 41', 42, 42') of the disengageable coupling, which abutments are operative in the direction of movement, against each other when the tape guide device is out of its operating position. When the tape-guide device (18, 18') is in its operating position the spring (45, 45') keeps said device in engagement with a positioning device (46, 46') which positions the tape-guide device, the drive member (26, 26' ) being moved with overtravel relative to the supporting member (19, 19') and the coupling abutments of the disengageable coupling (27, 27') being disengaged from each other against the force of the spring (45, 45').
