ABSTRACT:
A semicircular thrust arm has an anvil at one end and a rotatably mounted idler wheel at the other. The arm is pivotally mounted at its central portion in a predetermined tape player locale. A pushbutton activated lever mounts on the player and is aligned to forcibly engage the anvil on pushbutton depression. Anvil engagement causes the arm to rotate and forces the idler wheel into the cartridge pressure roller-player capstan interface whereby capstan rotation couples through the idler to the pressure roller. The idler thus reverses the rotatable drive to the pressure roller thereby reversing tape direction.
The rate of tape drive is controlled by selecting a particular ratio of idler wheel diameter to pressure roller diameter. The pressure roller consists of two cylinders fixed to rotate on a common shaft. The first cylinder is of selected diameter for normal tape speeds and the second cylinder, which is engaged by the idler, has a smaller diameter for increased speeds.
