ABSTRACT:
A stop/drive mode selector for a tape recording/playback device is capable of feather-touch operation by the plunger of a low power microsolenoid operating through a system of levers and springs. A pinch roller is mounted to a rotatable pinch roller lever. A pivotable drive roller lever, biased by a drive spring, is connected to the pinch roller lever by an interlocking lever. When a locking lever is released by actuating the solenoid, the drive spring, through the drive lever and interlocking lever, rotates the pinch roller lever to bring the pinch roller into contact with the constantly rotating capstan, which thereby drives the tape. When the interlocking lever is rotated by a second stroke of the solenoid plunger, a cam mechanism on the interlocking lever rotates the pinch roller lever to move the pinch roller away from the capstan, stopping the tape and allowing the drive spring to further rotate the drive lever. An eccentric gear on the drive lever then meshes with a drive gear on the capstan to return the drive lever and, through the interlocking lever, the pinch roller lever back to the tape stop mode in which the pinch roller is held out of contact with the capstan.
