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. The tape guide (32,33) situated in its operating position is disengaged from the displacement device (30) for this guide and is kept urged against the positioning device (68) by means of an urging device (78) provided on the support (70) for the positioning device (68), while the support (70) for the positioning device at the same time constitutes…
