Abstract
The invention relates to a magnetic-tape-cassette apparatus (1) comprising a deck for playing magnetic-tape cassettes (2), containing a magnetic tape (29). The deck includes at least one drivable capstan (30 or 31) and a pressure roller counterpart (35) which can be applied to the capstan. The pressure roller (35) and a magnetic head (27), past which the magnetic tape (29) is moved, are arranged on a head-mounting plate (26) which is withdrawn in a rest or fast-wind position and which is moved forwards in a play position. In the latter position the pressure roller (35), which is supported on a pivotable support (32) of the head-mounting plate (26), is pivoted against the capstan (30 or 31) by the support. Switching elements (39), for producing muting and/or track direction detection signals, are arranged on the head mounting plate (26) adjacent the pressure-roller supports (32), which elements can be set to a switch position by the pressure-roller supports (32) when these supports are pivoted as a result of the pressure rollers being applied to the capstans during operation of the deck. In this position the switching elements (39) provide muting and/or track direction detection at …
