To insure maintenance of a fixed position of tape which is being withdrawn from a cassette and looped in a predetermined tape path, a pressing engagement head (23) with a friction surface (24) presses the tape (4) against the scanning device (1) during withdrawal from, or return to, a cassette of the tape. Movement of the head (23) in clamping direction is controlled by a lever (9) which engages a cam (13, 15, 16, 17, 18), rotated by a drive shaft (14) upon withdrawal of the tape from the cassette and placement of the tape into a tape path, the initial position leaving the tape free around the scanning device, withdrawing movement clamping the tape against the scanning device by pivoting of the lever and hence engaging the clamping head (23) against the tape (4) and the tape against the scanning device (1). Preferably, the engagement is resilient, for example by interposition of a leaf spring (21).
