することを特徴とする原稿サイズ検知装置。[Claims for Utility Model Registration] In order to optically scan a document placed on a document placement plate, a first optical movable body and a second optical movable body are moved at a ratio of 2:1. A document size detection device that is installed in an image forming apparatus and detects a document size by determining the presence or absence of a document by a plurality of document detection sensors, comprising: a sensor support means for supporting the plurality of document detection sensors; When the movable body is stopped, the document detection sensor is located in the movement path of the second optical movable body so as to face the lower surface of the document placement plate, and when the optical movable body is moved, the document detection sensor is positioned in the second optical state. A document size detecting device comprising: a second state in which the sensor supporting means is positioned below a moving path of a moving body; and a driving means for moving the sensor supporting means.
