Abstract
An improved cassette tape recorder is disclosed in which a cam disc is used to move a head carriage between intermediate and recording/playback positions. When a playback, record or stop lever is pushed, a solenoid is energized to displace a lock arm to disengage the lock arm from a toothed cam plate integral with the cam disc, thus allowing the cam disc to rotate a half turn. A set plate for controlling pinch roller and take-up units is also operatively connected to the cam disc. The pinch roller is brought into contact with a capstan and a rotating shaft of the take-up unit is brought into engagement with a take-up base at the same time when the head carriage is shifted from the intermediate to the recording/playback position in response to the half turn of the cam disc. A lever arm connects the playback lever and the set plate so that the playback lever is moved into the playback position when the set plate is in contact with the smallest lobe of the cam disc, that is, during the recording operation.
