Claims

[Scope of utility model registration request]

A front tray fixed inside the copying machine body, a rear tray that can be freely pulled out of the copying machine body in the paper feeding direction, and a transfer paper stacked on the front tray and the rear tray connected to each other when the rear tray is closed. The copying machine is equipped with a paper feed tray consisting of a flexible holder that is folded into a substantially U-shape and held within the main body of the copying machine when operated, and a drive roller and a driven roller adjust the paper feed side position of the paper feed tray and the position of the photoreceptor. In the transfer paper feeding and conveying device of a copying machine, the transfer paper feeding and conveying device of a copying machine is provided with a conveying belt disposed and supported between near the transfer position and conveying the transfer paper fed from the paper feed tray toward the transfer position. A pressure roller that can freely approach and separate from the outer surface of the conveyor belt is provided at a nearby position, and is connected to the rear tray to press the conveyor belt when the rear tray is closed and to separate the conveyor belt when the rear tray is pulled out. 1. A transfer sheet feeding and conveying device for a copying machine, characterized in that a support member for supporting the pressure roller is provided.
