<p>PURPOSE:To reduce the number of parts and to thin the loader and also to improve the reliability of mechanical operations by providing a guide member for regulating the height of a 2nd circular-arcuate slider by abutting against a protrusion part of a 1st circular-arcuate slider. CONSTITUTION:The 1st circular-arcuate slider 33 has a small turning angle, and its outer periphery is held with a circular-arcuate slider gear part 33a meshing always with gears 75 and 77. On the other hand, the 2nd circular- arcuate slider 31 and a cam 34 are turned in the same direction covering approximately 180 deg.. Then, the guide member 83 is interposed between the sliders 33 and 31, and its integrally formed boss 83a is engaged with a long groove part 33b of the slider 33 to hold and guide the slider 33. This slider 33 is guided by the boss 83a and turned on the guide member 83. Then, when an end part 31a of the slider 31 is engaged with the guide member 83, and in this case, even when a bending and warpage are generated to some extent on the end part 31d, since the guide member 83 has a tapered surface 83b to be engaged, the slider 31 is guided underneath the guide member 83, so as to regulate the slider in height.</p> |
