ABSTRACT:
A recording and/or reproducing apparatus having a plurality of modes of operation, for example, at least recording and reproducing modes of operation, includes a main operating mode selecting device of the non-locked push-button type having push-button actuated switches which are selectively closed momentarily for applying a respective trigger signal to a self-holding operation controlling circuit which thereby assumes a condition corresponding to the selected mode of operation and maintains such condition until another trigger signal is received from the main operating mode selecting device, an auxiliary trigger signal generating circuit operative upon the supplying of electric power therethrough, for example, through a timer-controlled switch, to produce an auxiliary trigger signal, an auxiliary operating mode selecting device, for example, in the form of a manually actuable change-over switch, which is selectively disposable in an inoperative position and in one or more operative positions, for example, corresponding to automatically initiated recording and reproducing operations, and semi-conductor switching elements operative in response to the auxiliary trigger signal when the auxiliary mode selecting device is disposed in one of its operative positions to apply an automatic operation initiating trigger signal to the operation controlling circuit for causing the latter to automatically initiate the operation of the apparatus for which the auxiliary mode selecting device has been set.
