<p>PURPOSE:To automatically perform the regulation of a tape position without applying adjustment and to reduce the driving force to a tape by providing rotary oblique guides, respectively, and providing a lead which regulates the movement of the tape in a lateral direction generated by the rotation of a rotary oblique guide when the tape runs on a guide peripheral plane part. CONSTITUTION:When the tape 4 runs in the direction of (a) and runs on the guide peripheral plane part 5b by being folded by being wound on the rotary oblique guide 5 at a constant winding angle, the peripheral plane part 5b is rotated in a clockwise direction centering a shaft 5a. At this time, the tape 4 runs with remarkably low frictional resistance, and intends to move while being deviated in the lateral direction (c) along the shaft 5a of the guide 5. However, since the lead 2 exists on the peripheral plane of a cylinder 1 in the moving direction of the tape 4, the tape 4 is brought into contact lightly with the lower end face 2a of the lead 2, then, runs along the lower end face 2a. The tape 4 drawn out from the cylinder 1 passes the rotary oblique guide 6, thereby, the tape 4 runs with the low frictional resistance similarly as in the case of the guide 5, and is returned to original horizontal feed.</p> |
