Original reader returning the original after reading

摘要

An original autoreturn apparatus for use in a moving original exposure type original reader automatically returns an original (OP) read by a reader to an original inserting position. It includes a first photosensor (51) for detecting that the original (OP) is at the inserting position and outputting a corresponding detection signal, and a second photosensor (52) for detecting that an image sensor (1) finished reading the original (OP) and outputting a corresponding detection signal. In operation, the apparatus reverses the rotations of an original drive roller (3) and an original discharge roller (4) in response to the detection signal from the second photosensor (52) and causes the image sensor (1) to be inoperative and maintaining the reversed rotations of the original drive roller (3) and the original discharge roller (4) at least until the first photosensor (51) outputs the detection signal. Thus, the apparatus automatically returns the original (OP) which the image sensor has read to the original inserting position.
