PURPOSE:To obtain a low cost and steady operation mobile tape guide device, by securing the operation of the tape guide at the inlet and outlet sides each via the rotations of two rings which interlock the forward and backward rotations of the pinion. CONSTITUTION:The pinion 19 is turned into the desired direction by the reversible rotating drive means and then turned in the direction of the arrow A. Thus the outer and inner rings 17 and 18 turn in the directions of the arrows B and C respectively. Accordingly, both tape guides 4 and 5 interlocking the face rings 17 and 18 draw out the magnetic tape 10 from the tape cassette 9 to then coil the tape 10 up to the setting position. At the same time, the positioning is carried out for the guides 4 and 5 at the inlet and outlet sides each. And also the cam part 17a provided at the outer circumference part of the outer ring 17 has rotations, and thus the roller 27 can shift against the return spring 28 to press the pinch roller 26 to the capstan 7. As a result, the normal running becomes possible for the tape 10. |
