定を行なわせることを特徴とする給紙装置。[Scope of Claim for Utility Model Registration] Copy paper is selectively fed out from cassettes arranged vertically in the main body of an image forming apparatus such as a copying machine, registration timing is set, and the copy paper is transferred to an image bearing section. A paper feeding device that feeds paper in a blocked state, which forms a part of a paper feeding path formed between the cassette and the member for setting the registration timing, and is a part of the paper feeding path. a guide plate that is movable between an open position and an open position where the guide plate is separated from the paper feed path; and a lock that is integrated into one of the guide plates and fixes the guide plate when the guide plate is in the closed position. and a projection on the inner surface of the tiltable cover of the image forming apparatus main body that interferes with each guide plate in the open position to release the guide plates from the open position when the side plate is closed. and a protrusion that displaces the locking means on one of the guide plates in a state immediately before the closed position in a direction to temporarily release the lock, and as the cover is closed, The guide plates in the open state are displaced to the closed state by the projections, and the locking position of the locking means of one guide plate is temporarily released, and when the closed position is reached, again. A paper feeding device characterized in that a guide plate is fixed by the locking means.
