Abstract

A paper supplying device including first feed rollers eccentrically mounted on a horizontal rotational shaft, having convex feed surfaces whereby the feed rollers are capable of coming in contact with a first surface of a paper to fed, pressure rollers disposed as to face the feed surfaces of the feed rollers, for urging the paper toward the feed rollers while contacting the other surface of the paper, a separating plate arranged at the downstream side of the first feed rollers with respect to a feeding direction of the paper, for interrupting the movement of remaining sheets of paper other than the paper in contact with the convex feed surfaces of the first feed rollers, second feed rollers arranged at the downstream side of the first feed rollers with respect to the feeding direction of the paper, for feeding the paper in contact with the feed surfaces, according to an angular displacement of the first feed rollers and a transport arranged at a downstream side of the second feed rollers with respect to the feeding direction of the paper.

Claims

1. A paper supplying device which comprises:

first feed rollers eccentrically mounted on a horizontal rotational shaft, having convex feed surfaces whereby said feed rollers are capable of coming in contact with a first surface of a paper to be fed;

an urging means disposed so as to face said feed surfaces of said feed rollers, for urging said paper toward said feed rollers while contacting the other surface of said paper;

an interrupting means arranged at the downstream side of said first feed rollers with respect to a feeding direction of said paper, for interrupting the movement of remaining sheets of paper other than said paper in contact with said convex feed surfaces of said first feed rollers;

second feed means arranged at the downstream side of said first feed rollers with respect to said feeding direction of said paper, for feeding said paper in contact with said feed surfaces, according to an angular displacement of said first feed rollers; and

a transport means arranged at a downstream side of said second feed means with respect to the feeding direction of said paper.

2. A paper supplying device as in claim 1, wherein said urging means comprises a pair of spaced pressure rollers having a rotary shaft, each end of which is loosely inserted in an elongated opening of respective holding members.

3. A paper supplying device as in claim 1, wherein said interrupting means includes a separating plate having a lower surface whereon a friction member is attached, and urged toward said second feed means by means of a spiral spring arranged on a supporting shaft mounted on said separating plate.

4. A paper supplying device as in claim 1, wherein said second feed means is a paper feed roller.

5. A paper supplying device in claim 1, wherein said transport means includes two sets of two pairs of spaced upper and lower transport rollers, each set of each pair of spaced rollers being disposed on each side of said second feed means.
