<p>PROBLEM TO BE SOLVED: To improve reliability of operation of a reel driving mechanism and to make a device compact and thin by press-operating each operation member and forming so that each driving gear and each gear mechanism engage and link one another. SOLUTION: A first gear mechanism 23 has a first gear 23a rotated by a cam gear 22 rotated by a driving motor 20 and a second gear part 23b rotating a gear part 8b of a supply side reel mount 8. A second gear mechanism 25 has an idler gear 24 rotated by the second gear 23b of the first gear mechanism 23, a gear 25b for reproduction rotated by the idler gear 24, and a gear 25a for fast forwarding, and rotates with a winding side reel mount 7 integrally. A reproduction operation lever 31 moves the cam gear 23 in the direction of an axis line, a fast forwarding operation lever 33 moves the idler gear 24 in the direction of an axis line, a rewinding operation gear 34 moves the gear part 8b of the supply mount 8 in the direction of an axis line.</p> |
