求項１に記載のリール駆動機構。[Claims for Utility Model Registration] (1) A reel drive mechanism that uses a single motor as a drive source to perform play, reverse play, fast forward, and rewind operations, with a gear equipped with a motor that is capable of forward and reverse rotation. A pulley and a gear with an idler are rotatably supported independently of each other on the device board, and a lever having two groups of gears with different reduction ratios at both ends is rotatably supported on the device board, By swinging the lever and switching, one of the reduction ratios is selected, thereby switching between the playback speed and fast forward or rewind, and by switching the rotation direction of the motor,
A pail drive mechanism characterized in that operation switching is performed between play and rewind operations and reverse play and fast forward operations. (2) The reel drive mechanism according to claim 1, wherein the geared pulley and the idler gear are supported by a common shaft. (3) The reel drive mechanism according to claim 1 or 2, wherein the lever is substantially dogleg-shaped. (4) The reel drive mechanism according to claim 1 or 2, wherein the lever is approximately U-shaped. (5) Claim 1 characterized in that the gear group having a large reduction ratio consists of a combination of two gears, and a slip means is interposed between these two gears.
The reel drive mechanism described in . (6) The reel drive mechanism according to claim 1, wherein the gear group having a small reduction ratio is composed of three gears and performs two-stage reduction.
