JPS6428130A - Circulation system original feeding device - Google Patents

Abstract

PURPOSE:To eliminate the useless time in the circulation of a small quantity of originals by switching the intermittent revolution drive in a successive piling part to the continuous high speed revolution drive when the completion of the successive piling for the final original is detected and speedily feeding a successively piled original group into a recirculation part. CONSTITUTION:An original 1 supplied from an original feeding part A is discharged onto a successive piling tray 19 through a light exposure part B, branching plate 16, and the third roller 14. and slipped along said inclination, and sent out by 10-40mm through the prescribed intermittent turn of the fourth roller 20, and also the succeeding originals 1 are sent out similarly, and when the top edges of the originals are deflected, and the successive piling state is formed in a curved passage 22. When the successive piling for the final original 1 is completed, said completion is detected, and the third and fourth rollers 20 and 23 and a transport belt 24 are continuously driven at each high speed, and speedy feed is carried out until the top edge of a successively piled original group reaches a sensor 26. Then, the originals are retransported into the light exposure part B one by one by the intermittent drive of the transport belt 24 and the revolution of the fifth roller 27. Therefore, even for the circulation of a small quantity of originals, operation can be carried out without wasteful time.
