を特徴とする、自動原稿送り装置。 In an automatic document feeder that is attached to the main body of an image forming apparatus and is provided so as to be freely openable and closable between a closed position in which a document is conveyed onto a contact glass and an open position in which the contact glass is exposed, the automatic document feeder main body is A biasing force that has a biasing means that biases the automatic document feeder in a direction opposite to the direction in which it is intended to rotate due to its own weight, and the biasing force of the biasing means does not act on the automatic document feeder from a closed position. Until the end point of , the weight of the automatic document feeder and the biasing force of the biasing means are balanced, and from the end point of the biasing force to the end point of the opening/closing mechanism where rotation of the automatic document feeder is regulated, the automatic document feeder is in balance. An automatic document feeder characterized in that only the weight of the device itself acts.
