１項記載の画像形成装置。[Claims for Utility Model Registration] (1) Paper placed on a stack table is fed by a paper feed roller attached to the upper frame of the main body and a double-feed prevention mechanism attached to the lower frame of the main body. In an image forming apparatus including a bypass paper feeder and configured such that the upper frame and the lower frame of the main body can be opened and closed at a predetermined angle, the bypass paper feeder has a mechanism for conveying paper in conjunction with the opening/closing operation of the upper frame of the main body. A locking member configured to be freely retractable on the road is provided, and when the upper frame of the main body is opened, the locking member projects onto the paper conveyance path and prevents the paper on the stack table from entering the inside of the image forming apparatus. An image forming apparatus characterized in that it prevents. (2) Registration of a utility model characterized in that the locking member is provided in conjunction with the lever for opening the upper frame of the main body, and protrudes onto the paper conveyance path when the lever is operated when opening the upper frame. An image forming apparatus according to claim 1.
