Cassette-type recording and/or reproducing apparatus with inadvertent

Abstract

In an apparatus for recording and/or reproducing signals on a magnetic tape contained in a cassette having at least one aperture which is alternatively obstructed or unobstructed to respectively indicate that signals may be recorded on the tape or that the tape already has signals recorded thereon which are not to be erased; a detector is engageable with an operatively positioned cassette at the aperture of the latter and has first and second states in dependence on whether the aperture is obstructed or unobstructed, respectively, a record push-button is actuable from a rest position to an operative position with the detector in either of its states, and a change-over mechanism changes-over the apparatus to its recording mode of operation in response to actuation of the record push-button only when the detector is in its first state. An ejector is also provided for ejecting the tape cassette from its operative position in response to actuation of the record push-button with the detector in its second state. Further, a lock, which is normally operative to hold the actuated record push-button in its operative position, is released in response to the second state of the detector, and an indicator is made operative to indicate that the operatively positioned cassette has an unobstructed aperture in response to the actuation of the record push-button with the detector in its second state.
