<p>The mechanism has a toothed ring for tape application, carrying a pressure roll for a pull-out pin for taking out the video tape from a cassette and bringing it into recording or playback position. A drive motor rotation is transmitted to the ring by a gear train. A group of control keys switches over the gear train, when a change in the ring rotation direction is required. The ring rotation is stopped by a mechanism interrupting the transmission gear train operation. The gear train has a lever plate with a gear (37) for forward rotation of the ring, and a swivel level with a gear for the ring reverse rotation. The plate and lever are actuated by the recording to playback keys, via a cam section on a slider. The cam section connects the drive motor, when depressed, while on release it actuates the motor reverse rotation.</p> |
