ABSTRACT:
The invention relates to a device for changing modes of a cassette tape recorder, which facilitates reduction of power consumption as well as reduction of noise. A selection gear, hinged on a selection lever, is disengaged from the main gear during which play, record, reverse play, or reverse record mode is selected, during which the selection gear has been engaged with the main gear in stop condition. This prevents movement of the selection lever, unnecessary rotation of the selection gear, and accordingly, prevents the motor driving the main gear from being overloaded.
The device for changing over of modes of a cassette tape recorder includes a transmission lever fixed on a pinch gear shaft for being primarily rotated by a solenoid lever and for being secondarily rotated by a cam gear when play, record, reverse play, and reverse record mode is selected. A selection lever is movably fixed on the same shaft with a main gear, and is movable in an up and down direction. The selection lever is moved downward to disengage the selection.
