Abstract
An image forming apparatus has an automatic original feeder for conveying an original along a path to a transparent platen. This automatic original feeder conveys the original to a position where it lies between the platen and an original conveying device which is disposed on a frame which can cover the transparent platen. The frame is rotatably supported by a supporting member. This supporting member is attached movably up and down relative to the main body of the apparatus and it is elastically urged downward. This biases the original conveying device downwardly, so that the pressure applied to the original by the original conveying device is properly maintained, thereby ensuring reliable conveyance of the original. Clearances between the original conveying device and an original cover plate on the frame are covered with clearance covering members, thereby to prevent an outline of the original conveying device from appearing in a transferred image. The supporting member can be attached to the main body of the apparatus through an adapter member, thereby allowing a single model of automatic original feeder to be mounted on different types of image forming apparatuses. The original conveying device is reversible, the transparent platen has an inclined surface at its infeed/outfeed end, and the feeder has holding extensions which hold down the infeed end of the platen on opposite sides of the original's path.
