<p>PURPOSE:To stabilize the operation of the tape deck by applying spring force to idlers which are provided oppositely and controlling idlers with a sliding plate which slides and also rotates with a fast-forward lever and a rewinding lever. CONSTITUTION:When a rewind button is operated, the rewinding lever 17 is elevated, so the sliding plate 14 rotates clockwise around a guide pin 15 as a fulcrum. When an operation pin 10a is released and an operation pin 9a is further moved to right to insert the operation pin 10a into the projection hole part 19d1 of a head base 19; and the 2nd idler 12 is drawn by a tension spring 13 and interposed between a driving pulley 4 and a payoff reel 6 to transmit rotational force. When the fast-forward lever 16 is elevated, on the other hand, the sliding plate 14 is rotated counterclockwise to release the operation pin 9a while the operation pin 10a is still controlled, and the 1st idler 11 is pressed against a flywheel 2 and a take-up reel 6 with a tension spring 14. Consequently, the transmission mechanism for fast-forward and rewinding operation is simplified and the switching is secured.</p> |
