供纸装置
摘要：
一种供纸装置，包括纸张支撑元件、供纸单元、具有引导表面的引导元件，其改进在于，在引导元件中设置有一止动件，该止动件具有一防止堆垛滑动的表面，该表面与引导表面相比具有更高摩擦系数，止动件与一止动件移动机构相接合并由该止动件移动机构选择性地在突出位置和收回位置之间移动，在突出位置，防止堆垛滑动的表面沿着与供纸方向相反的方向从引导表面突出到与纸张堆垛接触的位置，在收回位置，防止堆垛滑动的表面沿着供纸方向从引导表面收回至与纸张堆垛脱离接触的位置。这种供纸装置能正确地一次一张地供给纸张，不会产生供给双层纸张的问题，并能防止柔软纸张突然滑到下游。
摘要（英）：

The utility model provides a paper feeding device, composed of a paper support element, a paper feeding unit, an induction element which has the directing surface. The improvement is that the induction element is provided with a retainer which has a surface to prevent the piling sliding. The surface has the higher coefficient of friction compared with the directing surface. The retainer are engaged with its mobile mechanism, and the mobile mechanism of the retainer moves between the projecting position and withdrawal position selectively. In the projecting position, the surface which prevent the piling sliding projects from the directing surface to the position connected with the paper piling in the opposite direction of the paper feeding. In the withdrawal position, the surface which prevent the piling sliding retracts from the directing surface to the disengaged position to the paper piling in the opposite direction of the paper feeding. The paper feeding device can feed the paper one at a time, and can not bring the problem of feeding the double layers of paper. Also the device can prevent the paper sliding to the lower reaches suddenly.
