<p>PURPOSE:To improve the workability for assembling and decomposition by moving a supporting shaft provided on a tape guide body in the horizontal direction to engage an engaging groove of the supporting shaft with the hole part of an odd-shaped hole after the supporting shaft is inserted to an insertion hole of the odd-shaped hole provided in a link against a flat spring. CONSTITUTION:A supporting shaft 14a is inserted to an insertion hole 17a against a flat spring 18 and is so adjusted that an engaging groove 14b is level with a link 16, and the supporting shaft 14a is moved in the horizontal direction so that the engaging groove 14b is engaged with a hole part 17b. The flat spring 18 is restored to the original position, and a contacting part 18a of the flat spring 18 is placed on a side of the supporting shaft 15a. Therefore, the engaging groove 14b is engaged with the hole part 17b to prevent the supporting shaft 14a from slipping in the vertical direction, and the contacting part 18a of the flat spring 18 is brought into contact with the peripheral part of the supporting shaft 14a to prevent the supporting shaft 14a from slipping in the horizontal direction, and a tape guide body 14 and the link 16 are freely rotatably coupled to each other. By this constitution, the mechanism is made small-sized and thin and the workability for assembling and decomposition is improved.</p> |
