<p>PURPOSE:To improve reliability and also to simplify a mechanism by reducing the number of components of a pinch-roller driver, by realizing a pinch-roller driving method by one motor as well as the loading and unloading of a tape. CONSTITUTION:Depressing a reproducing or recording button causes motor 29 to rotate in a loading direction. As a result, guide bodies 27 and 27', after loading a magnetic tape on cyclinder 12, are positioned by engagement members 41 and 41'. Then, pinch roller 22 comes in pressure contact with capstan 21 by motor 29. At the same time, motor 29 stops. The moment a stop button is depressed so as to release the recording or reproducing state, motor 29 turns in an unloading direction to free pinch roller 22 and guide bodies 27 and 27' move backward for unloading. In this way, the pinch-roller driving method is performed by one motor and the mechanism can be simplified.</p> |
