Abstract
In a paper feed device having a storage for storing thereon a pile of paper leaves and a device for feeding the paper leaves piled on the storage, there is provided separating apparatus for separating an uppermost one of the paper leaves to be fed by the feeding device from the other paper leaves and a blower disposed adjacent to the rear end of the piled paper leaves with respect to the direction of the feed thereof for blowing a flow of pressurized fluid in the direction of feed of the paper leaves. The blower is movable for retraction with respect to the rear end of the piled paper leaves.
Claims1
A paper feed device comprising:
- means for storing a stack of paper leaves to be fed;
- means, located above said storage means, for feeding the topmost paper leaf on the stack in a forward direction;
- means, located at the front end of said storage means, for separating the topmost paper leaf from the stack to allow said feeding means to feed the topmost paper leaf only;
- blowing means for applying pressurized air from adjacent the rear end of the stack in the forward direction at a position remote from the topmost leaf to render the leaves easily separable from adjacent leaves;
- and
- control means for actuating said blowing means at a predetermined time after said feeding means starts to feed the topmost leaf from said stack.
