Claims

[Claims for Utility Model Registration] (1) A feeding device that is movable toward and away from the upper surface of paper on a stacker, and the paper taken out into a feeding path by this feeding device, by a drive motor that can be reciprocated in forward and reverse directions. In a paper feeding device comprising a feeding rotary body for taking in and feeding, and a separating means comprising a separating body disposed close to the feeding rotary body and separating a second sheet and subsequent sheets, the sheet feeder is provided with: 1. A paper feeding device comprising an opening/closing means for opening/closing the feeding path in conjunction with the approaching and separating operations. (2) The feeding means is provided at the front end of a swinging arm that swings in accordance with the forward and reverse rotation of the drive motor on the shaft of the feeding rotary body, and the opening/closing means of the feed passage is spaced apart from the feeding means. It is fixedly installed on the feed passage opening/closing shaft located at the
a stopper member biased in a direction to close the feeding passage; an opening/closing drive arm that is fixed to the shaft of the feeding rotary body and makes the same swinging motion as the swinging arm of the feeding means; 2. The paper feeding device according to claim 1, further comprising an opening/closing driven arm that is fixed to the feeding path opening/closing shaft and operates in conjunction with the opening/closing drive arm.
