Document Type and Number:
Japanese Patent JP2978093
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the tension on a feed belt from fluctuating by holding a second frame in a predetermined position relative to a drive sprocket via a drive bearing hole, and supporting a feed belt so that it has predetermined tension while keeping a predetermined relationship with the drive sprocket.
SOLUTION: A second side frame 12 is held in a predetermined position, via an almost round drive bearing hole, relative to a drive sprocket 15 engaged with a drive shaft DS, and a feed belt 25 is supported by a belt guide 18 integrated with the second side frame 12, while having predetermined tension and keeping a fixed position relative to the drive sprocket 15. Also, a first side frame 11 is kept in a fixed position relative to a positioning shaft SS via a positioning bearing hole 19. Even if a center distance T fluctuates, the feed belt 25 is supported by the belt guide 18 integrated with the first side frame 11, while keeping a predetermined position relative to the drive sprocket 15. Therefore, tension does not fluctuate.
