Claims

[Scope of utility model registration request]

A paper feeder that can sequentially feed the same sheets of paper stacked on a paper feed tray, and by attaching a paper feed cassette to the paper feed tray, can sequentially feed the sheets stacked and stored in the paper feed cassette. In the apparatus, a guide plate is provided on the paper feed tray so as to be movable according to the paper size in contact with the edges of the stacked papers and guide the paper, and the amount of movement of the paper is determined by the amount of movement of the guide plate. A paper size detection means for detecting the size is provided, a cutout hole is provided in the bottom plate of the paper feed cassette through which the guide plate passes, and the guide plate guides the paper and detects the size even when feeding paper from the paper feed cassette. A paper feeding device characterized in that it performs the following.
