The invention relates to a magnetic tape apparatus having at least two push buttons (31, 32) which, when their push-button bars (33, 34) are pressed in separately, exercise individual functions on apparatus parts, with it being possible for each of the push-button bars (33, 34), loaded in tension by means of springs (50, 51) in the direction of their initial neutral positions, to be arrested in the pressed-in position, and with it being possible for a spring-loaded blocking member (20) which can be moved by all push-button bars (33, 34) and which interacts with latches on the push-button bars (33, 34) to be adjusted in such a way that, when a push-button bar is pressed in, a push-button bar arrested beforehand is released for withdrawal. In addition, the individual latches (52, 53) of at least two push-button bars (33, 34) with the parts of the blocking member (20) which are allocated to the individual latches (52, 53) have latching arrangements of different design. The different latching arrangements are constructed in such a way that the push-button bars (33, 34) having a different latching arrangement, when they are alternately pushed in, are released by the blocking member (20) for withdrawal. Moreover, it is provided that the blocking member (20), when these push-button bars (33, 34) are pushed in together, likewise releases these two push-button bars for withdrawal. |
