- 摘要：
- PURPOSE:To omit an idler and an operation switching mechanism, by adopting a two-way DC motor for the magnetic tape traveling equipment. CONSTITUTION:When a two-wat DC motor 42 is set to a mode of play or recording by the push-button, it rotates at a constant speed, and when it is set to a high speed mode by the quick-feed button, it rotates in one direction or the other direction at a high speed. To the output shaft of the DC motor 42 are fixed the first pulley 44 which has been placed on the same plane with fly-wheels 38, 40, and the second pulley 46 which has been concentrically formed on the upper surface of this pulley 44. The first driving belt 48 is held fast to the first pulley 44 and the grooves for operating as a pulley, which are formed on the outside circumferential surface of one pair of fly-wheels 38, 40.
