Title: Heating device
Inventor: OKADA TAMOTSU
IPC: G03G15/20
Filed: 1990-02-20
Abstract: PURPOSE:To stably control film approaching by fixing the frame body of a fixing device in a main body device by three points; two of which are disposed on a film driving side and one of which is disposed on a non-driving side in the longitudinal direction of a heating device. CONSTITUTION:The frame body of the fixing device is attached to the main body device by fixing by three-point support; two points are disposed on the inner side of the main body where the film is driven, and one point is disposed on the front side where the film is not driven. By having the three points as the fixed positions in such a way, this device has an advantage to bearing surface accuracy on the main body side and to a twist, and even in the case that the device itself is placed on non-leveled place, the influence on the fixing device can be kept to a minimum. And also, the reason why two points are disposed on the film driving side is that twisting strength in a fixed direction is surely given to the fixing device when the driving is given from the main body side. Thus, the twist toward the fixing device can be restrained to a mini mum, and then, the film approaching can be stably controlled.
