A novel cassette changer for a tape player wherein a tape cassette accommodating member and a tape driving mechanism are fixed relative to each other during selection of a tape cassette and which has a comparatively small overall size and requires a comparatively low power for moving a tape cassette between the tape cassette accommodating member and tape driving mechanism. The cassette changer comprises a plurality of cassette receiving members each for removably receiving a tape cassette thereon, an accommodating member for receiving the cassette receiving members in a row thereon, an actuating means for selectively moving a cassette receiving members from a home position to a transfer position, a tape driving mechanism mounted in a fixed relationship with respect to the accommodating member for receiving a tape cassette thereon and driving a tape of the tape cassette, and a carrier for receiving a tape cassette from the selected cassette receiving member moved to the transfer position and setting the tape cassette in position onto the tape driving mechanism.

A frequency/voltage conversion circuit is provided with a detection circuit for determining when the input frequency rises above a predetermined level which threatens to inhibit operation of flip-flop devices in the circuit. In response to the detection, a capacitor of a first charging/discharging circuit is forcibly charged to a value above a predetermined level.
