Abstract

The object of the invention is to a paper tray unit includes a paper size sensor which is attached to a paper tray and determines a paper size in a paper width direction by detecting a position of a paper width guide. In the paper tray unit, a movable member moves in a paper feed direction accompanying movement of the paper width guide. The position of the paper width guide is detected by the paper size sensor detecting or not detecting the movable member.

Description

technical field [0001] The present invention relates to a paper tray unit for placing paper to be supplied by a paper feeding path, and more particularly to a paper tray unit movably provided on its surface perpendicular to the paper feeding direction for positioning the paper in the width direction A paper tray unit is provided with a paper size sensor for detecting the width direction size of the paper by detecting the position of the paper width guide on the back of the guide part. Background technique [0002] Many scanners, facsimile machines, copiers, and the like are equipped with an image reading device for reading image information of a document. As one of the image reading methods of the image reading device, there is a sheet-feed method in which images are read while sequentially feeding a plurality of originals. This paper feeding method is mainly realized by an automatic document feeder (hereinafter referred to as "ADF"). Figure 8 It is a schematic longitudina...
