<p>PURPOSE:To make a device thin by constituting driving rings, which drive loading posts with circular gears having tooth parts on outer or inner peripheral surfaces and guiding and rotating circular gears along the peripheral part of a rotating drum only by wall bodies which guide their outer and inner peripheral surfaces. CONSTITUTION:Loading post driving rings are constituted of circulate gears 14 and 15 which have tooth parts on outer or inner peripheral surfaces and are rotated and driven, and wall bodies 29 and 30 which guide outer and inner peripheral surfaces of these arcuate gears 14 and 15 are disposed along the peripheral part of a rotating drum 13. Wall bodies 29 and 30 which guide outer and inner peripheral surfaces of circulate gears 14 and 15 are constituted integrally and a guide plate 32 which can surely guide the movement of the circulate gears turning along wall bodies 29 and 30 is provided on a part in the peripheral direction of the upper edge part of at least one of wall bodies 29 and 30 constituted integrally. Thus, the gap between both circulate gears 14 and 15 is narrowed to make the device thin.</p> |
