[0002]
In the existing paper feeding device, 100ms after the tray outlet motor of the paper feeding box is started, the next sheet of paper starts to float up, and the fan at the front end and the side fan at the front end start to blow air, so that the paper in the paper feeding box floats and is being conveyed. The piece of paper that is floating will come into contact with the next floating paper, so that the next paper is easily taken away by the paper that is being conveyed, which may cause problems such as paper jams and double feeding during continuous paper feeding.

Embodiment Construction
[0019] The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The expression of the structural position of each component such as up, down, top, bottom, etc. in the description is not absolute, but relative. These directional expressions are appropriate when the various components are arranged as shown in the drawings, but when the positions of the various components in the drawings are changed, these directional expressions are also changed accordingly.
[0020] As mentioned in the background art, in the prior art, the next sheet of paper begins to float 100 ms after the tray exit motor of the paper cassette is activated. For ordinary size paper, since the contact and overlap range between the paper being conveyed and the next paper is relatively small, there is no proble...

The invention provides a sheet feeder and an image forming apparatus. The paper feeding device comprises a paper feeding box, a plurality of fans, a carrying belt and a carrying roller. Wherein the plurality of fans comprise a tip fan, at least two side fans and a suction fan; wherein the front end fan has a paper blowing and floating state and a paper separating state, the paper feeding device further comprises a control part, and the control part is configured to control the front end fan to be switched to the paper blowing and floating state according to the length of paper to be conveyed and start the at least two side face fans. The image forming apparatus includes: a paper feeding device configured to convey paper; and an image forming mechanism for forming an image on the sheet.
Description
technical field [0001] The present invention relates to a paper feeding device and an image forming device including the same. Background technique [0002] In the existing paper feeding device, 100ms after the tray outlet motor of the paper feeding box starts, the next sheet of paper starts to float up, and the fan at the front end and the side fan at the front end start to blow air, so that the paper in the paper feeding box floats and is being conveyed. The sheet of paper will come into contact with the next floating sheet of paper, so that the next sheet of paper is easily taken away by the sheet of paper being conveyed, which may cause problems such as paper jams and double-feeding during the continuous feeding of paper. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the prior art, the present invention provides a paper feeding device and an image forming device, which can reduce paper feeding problems such as paper jams...
