ABSTRACT:
A magnetic recording and reproducing device wherein operation timings of various mechanisms can be set with a high degree of accuracy and construction for driving the individual mechanisms is simplified with a reduced number parts. The device comprises a single cam plate having cams for selectively operating a turning force transmission change-over mechanism, a tape loading mechanism, a pinch roller driving mechanism, a rotational speed change-over mechanism, a brake mechanism and a back tension mechanism. The cam plate is driven to rotate by a motor and transmits the turning force of the motor as a driving force to the mechanisms listed. The brake device is also improved in that slackening of a tape is not caused for a time after completion of a fast feeding mode or a rewinding mode until a reproducing mode or a recording mode is subsequently started.
