ROTATING BELT MECHANISM AND PHOTOGRAPH DEVELOPING DEVICE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a rotating belt mechanism whose rotating belt is hard to be removed from an end part roller, and a photograph developing device using it.;SOLUTION: A drying part 46 of a photograph developing device is furnished with an endless rotating belt 50, a pair of end part rollers 52, 54 on which the rotating belt 50 is wound around and to add torque to the rotating belt 50 and a tension roller 56 to add tension to the rotating belt 50 by making contact with an inner peripheral surface 501 of the rotating belt 50 as well as provided in the neighbourhood of the end part roller 52. Additionally, a pressurizing roller 64 to pressurize an outer peripheral surface 50R of the rotating belt 50 and to increase a belt winding angle of the end part roller 52 is provided between the tension roller 56 and the end part roller 52. Consequently, as a contact area of a roller surface of the end part roller 52 and the rotating belt 50 increases, the rotating belt 50 becomes hard to meander, and consequently, the rotating belt 50 becomes hard to be removed from the end part roller 52.;COPYRIGHT: (C)2001,JPO
