<p>PURPOSE:To surely and instantaneously stop the tape-like body by cutting off forcibly a driving force transfer to a reel base, and also, applying the braking in the case of stopping the tape-like body which is running at a high speed. CONSTITUTION:When a tape stop instruction is inputted to a system controller 29 from an operating part 35, or a tape terminal detecting signal by a tape terminal detector 30 is inputted to the system controller 29, the system controller 29 outputs a stop instruction to a capstan motor 26 through a motor control circuit 28, and simultaneously, outputs an instruction for cutting off an electric conduction to an electromagnet. By following it, a plate cam 34 is released and moves quickly in the direction (y) by energizing force of a spring 38, and idle gear 25c is separated instantaneously and forcibly from a gear 22 through a lever 37, a transfer of driving force to a winding reel base 21 from the capstan motor 26 is detached, and subsequently, brakes 31, 32 are released and braking is applied to reel bases 23, 21 and they are stopped.</p> |
