发明名称 DRIVER OF ENDLESS BELT FOR ELECTROPHOTOGRAPHIC DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a driver for an electrophotographic device, preventing the separation of the joint of a guide rib by correcting the transverse sway of an endless belt by means of a driving roller, and capable of stably driving the belt over a long period. SOLUTION: In a driver of an endless belt 1 comprising a flexible filmlike base material formed in an annular shape and a guide rib 3 made from a flexible material and bonded along the side edge of the inner peripheral surface thereof, a driving roller 5 having a mechanism for detecting the transverse sway of the endless belt 1 and for tilting its own rotation axis is retained; that is, when the endless belt 1 is rotated and run using the driving roller 5, meandering of the endless belt 1 occurs, and in the event of the transverse sway of the endless belt 1 to the left, a roller main body 6 is also deviated to the left along with the endless belt 1. When the roller main body 6 is deviated to the left, a bearing 8a moves along a roller support shaft 7a while a bearing 8b moves along a roller support shaft 7b, causing the roller main body 6 to fall at the right side and rise at the left side. As a result, the roller main body 6 is tilted in the take-over direction of the endless belt 1 as shown by the two- dot chain line in (B).
