Abstract
A document size detecting device according to the invention is adapted to be mounted in an image forming device for a copying machine or the like, comprising an arm adapted to be folded and unfolded in operative association with the forward and backward movements, respectively, of the optical section of the image forming device, and a plurality of optical sensors attached to the arm at predetermined positions thereon corresponding to various format sizes of documents. When the arm moves to a document detecting position, a downwardly extending projection thereon moves onto a support member, thus supporting the arm at a predetermined position to keep the optical sensors at a predetermined distance from the document-supporting contact glass.
