<p>PURPOSE:To obtain a tape loading device whose constitution is simplified and in which a small motor can be used. CONSTITUTION:In a reproducing mode, a motor 34 is turned, and a fan-shaped rotary gear 30 is turned to the counterclockwise direction. Thereby, a second intermediate gear 40 and a third intermediate gear 41 are turned, individual swivel levers 42, 43 which are fixed to them are turned, and intermediate levers 12C, 12D which are attached to their tip parts and a guide roller 11 are raised along slide grooves 22A, 22B. In addition, a pinch lever 50 is turned to the clockwise direction via a link 44 which is attached to the upper end part of the fan-shaped rotary gear 30, a rotary lever 40 and an intermediate lever 48, and a pinch roller 23 is brought close to a capstan 25. Since a tape loading device 1 is constituted mainly of rotating components, it is constituted simply as compared with conventional case in which a tape loading device is constituted mainly of sliding components. In addition, since the loss of a transmission force is reduced, the motor 34 which is small can be used.</p> |
