    • A paper feeding apparatus with a paper size determining means includes a paper tray, paper guide, a belt, a roller set, a sensing mechanism and a control unit. The paper tray has a front surface for supporting paper and a rear surface. The paper guide is movably disposed on the paper tray and for abutting against an edge of the paper in the paper tray. The roller set is rotatably disposed on the rear surface. The belt, connected to the paper guide and wound around the roller set, synchronously moves the paper guide and rotates the roller set. The sensing mechanism disposed on the rear surface senses a to-be-sensed component disposed on the belt or the roller set and thus outputs a sensing signal. The control unit receives the sensing signal and thus determines size of the paper.
    • 具有纸张尺寸确定装置的送纸装置包括纸盘,纸张引导件,皮带,滚子组,感测机构和控制单元。 纸盘具有用于支撑纸张的前表面和后表面。 纸张引导件可移动地设置在纸盘上并且抵靠在纸盘中的纸张的边缘。 辊组可旋转地设置在后表面上。 连接到导纸器并缠绕在辊组上的皮带同步移动纸张导板并旋转滚筒组。 设置在后表面的感测机构感测设置在皮带或辊组上的被感测部件,从而输出感测信号。 控制单元接收感测信号,从而确定纸张的尺寸。
