<p>PURPOSE:To arrest or reduce gear noises and to make a recorder and reproducing device thinner in thickness, by constituting the device in such a way that the rotating direction is changed and rotating speed is reduced by means of a worm gear and worm wheel. CONSTITUTION:Since a worm wheel 14 and gear 15 rotate counterclockwise when a worm gear 13 is rotated in a prescribed direction by means of a motor 12, a transmission gear 16 revolves counterclockwise without rotating together with an arm 17 by the action of a clutch 19 until the gear 16 is engaged with a feeding reel turntable 19. When the gear 16 is engaged with the reel turntable 20, the gear 16 rotates clockwise and causes the reel turntable 20 to rotate counterclockwise. When a winding reel turntable 21 is rotated, the worm gear 13 is rotated in the opposite direction by means of the motor 12. When the transmission gear 16 is engaged with the reel turntable 21, the gear 16 rotates counterclockwise and causes the reel turntable 21 to rotate clockwise.</p> |
