ABSTRACT:
A retention device for a cassette tape recorder comprises a cassette holder, a platform, a movable plate, a slide plate and a retention lever. The cassette holder is adapted to receive a tape cassette and is movable vertically so that the tape cassette may be engaged and disengaged with the tape drive means. The platform supports magnetic transducer heads and a pinch roller and is slidable so as to cause the heads and pinch roller to come into engagement with the magnetic tape in the cassette. The movable plate is moved with the platform, when it is moved to engage the heads with the tape in the cassette.
The slide plate is slidably mounted on the movable plate, and a tension spring interconnects them; so that the slide plate is moved with the movable plate. The range of the movement of the slide plate is limited to be less than that of the movable plate. The retention lever is pivotally secured at one end on the slide plate, and a mid-point of the lever passes through a hole in the rear portion of the base of the cassette holder so that the other end of the lever may be rotated with respect to the holder. With the movement of the platform, the movable plate, and consequently the slide plate, the retention lever rotates to press the tape cassette firmly against the transducer heads and pinch roller.
