    摘要： An image forming apparatus comprises a paper feed tray, which is attached to the apparatus body so as to be freely opened and closed with respect to the apparatus body, and a paper pressing plate disposed inside the apparatus body. The paper feed tray has a pair of protrusions on the inner surfaces of the side walls thereof. The paper pressing plate has a pair of notches formed by partially cutting the side portions of the plate so that, when the paper feed tray is in the closed position, the protrusions of the paper feed tray are received in the notches and the side faces of the paper pressing plate where the notches are formed face the protrusions in a manner that are almost in contact with the protrusions. When a force acts on the paper feed tray in the closed position to bend inward the side walls of the paper feed tray, the protrusions are pressed against the portions of the paper pressing plate where the notches are formed so as to stop the inward bending of the side walls. Accordingly, even when a user grasps the paper feed tray to lift the apparatus, the paper feed tray can be prevented from becoming detached from the apparatus body.

    摘要： An image forming apparatus comprises a paper feed tray that can be opened and closed with respect to the apparatus body and a cover tray that can double as a manual feed tray. The paper feed tray has first side walls and first protrusions formed on the inner surfaces of the first side walls. The cover tray has: connection portions that are configured to be detachably connected to pivot shafts provided at the apparatus body and that are connected to the pivot shafts so as to rotate about the pivot shafts; second side walls; and second protrusions formed on the outer surfaces of the second side walls. The cover tray serves as a cover for covering sheets of paper stacked on the paper feed tray when it is in a position where the second protrusions are located below the first protrusions. The cover tray serves as a manual feed tray when it is in a position where the second protrusions are placed on the first protrusions so that the cover tray is inclined with one end adjacent to the pivot shafts located lower than the other end.
