Abstract

PURPOSE:To achieve take-up force and automatic stopping and driving force at a limited space surely, by making a fulcrum common for a cam gear driven with an idler gear which switches and delivers the torque of a capstan to a gear for windig reel and for an idler lever. CONSTITUTION:At a recording or playback mode, an idler lever 44 turns clockwise by taking a fulcrum 43 as an axis through the elastic force of a spring 45 until a lever 47 contacts with a pin 17a, via an exchange lever 47 in which latching with the pin 17a of a main lever is released. Thus, the torque of a capstan gear 29 is always delivered to an automatic stopping cam gear 49 taking the fulcrum 43 as a common fulcrum, and an idler gear 50 borne to the lever 44 is coupled with a friction gear 51 for winding reel and take-up force is delivered only at recording or playback. With this constitution, the take-up force and the automatic stopping and driving force can be picked up surely with a limited space.
