Abstract

PURPOSE: To secure repeated feed of the same paper sheet in the case of the paper feeder of a both-sides copier without any pinch roller, by means of a multi-feed preventing retard roller and a paper leading edge entry guide plate installed near the feed roller.
CONSTITUTION: A paper sheet 13 with its one side already printed stays in its standby position alter its leading edge is inserted between a feed roller 3 and an entry guide plate 10 by means of the transporting pressure and dropping inertia of the weight, and those copied paper sheets are thus piled there successivly. Next, when the roller 3 is driven, transportation of paper sheet 131 is started. Then, the paper sheet just above said paper sheet 131 is transported simultaneousy but it is blocked after being separated from the lower paper sheet 131 owing to the reverse rotation of a retard roller 4. The paper sheet 131 is after reaching transport rollers 12, accelerated by high rotational speed of rollers 12 through allowable racing of a one-way clutch 3c. Here, when the trailing edge of the paper sheet 131 leaves the roller 3, the speed is recovered to its origianl level to be ready for starting transportation of the next paper sheet.
