Claim 1
Independent Claim
154 words
An automatic original conveying device for conveying an original to a reading position and thereafter retracting the original from the reading position, comprising: means for supporting originals; feeding means for separating and feeding a lowermost one of the originals supported on said supporting means at a first speed; first guide means for leading the original fed by the feeding means to the reading position in a reversed state to that of the originals located on the supporting means; retracting means for retracting the original led to the reading position, at a second speed faster than the first speed, from the same side as that at which the original has been led to the reading position; and second guide means for returning the original to the supporting means from the same side as that from which the original has been fed, in a reversed state to that of said original retracted from the reading position.
Claim 2
Dependent Claim
154 words
An automatic original conveying device for conveying an original to a reading position and thereafter retracting the original from the reading position, comprising: means for supporting originals; feeding means for separating and feeding a lowermost one of the originals supported on said supporting means at a first speed; first guide means for leading the original fed by the feeding means to the reading position in a reversed state to that of the originals located on the supporting means; retracting means for retracting the original led to the reading position, at a second speed faster than the first speed, from the same side as that at which the original has been led to the reading position; and second guide means for returning the original to the supporting means from the same side as that from which the original has been fed, in a reversed state to that of said original retracted from the reading position.
