Background technique

In today's advanced information technology, even though digitized electronic data is easy to transmit, store, and even be directly displayed on the screen through a display device, due to backup requirements, confidentiality requirements, and confirmation of rights and obligations, it is easy to carry and read instantly. .. etc., there is still a lot of information such as text, images, and tables that must be printed on the surface of the paper.

In the era of massive information generation, the demand for copying, printing and transmitting paper is increasing. The most common electronic devices for copying, printing and transmitting paper include photocopiers, scanners, list machines, fax machines and so on. In order to process multiple copies of paper at a time, a paper feeding mechanism (paperfeeding mechanism) will be provided in the above-mentioned device, the most common of which is an automatic document feeder (Auto Document Feeder; ADF), which is used to feed multiple copies of paper into this type of electronic device. device.

Please refer to FIG. 1A . FIG. 1A is a schematic structural diagram of a conventional paper feeding mechanism 2 . The paper feeding mechanism 2 can be applied in electronic devices (not shown) such as photocopiers, scanners, list machines, facsimile machines, etc., and the paper feeding mechanism 2 can also make the paper 4 every The pages are separated, which means they can be automatically fed one by one. The paper feeding mechanism 2 includes a paper feeding area 6 , a cam 8 , a lifting plate 10 , a first driver 14 , a rubber roller 16 , and a second driver 20 .

When the paper feeding mechanism 2 senses that the paper 4 entering the electronic device has reached a predetermined position, the second driver 20 drives the rubber roller 16 to rotate. The predetermined position may mean that the paper 4 leaves the electronic device, or it may mean that the paper 4 is located at a certain position in the electronic device. By rotating the rubber roller 16 to drive the paper 4 , the paper 4 can be fed into the electronic device one by one to perform functions such as copying, printing, or sending the paper 4 . Wherein, the paper feeding mechanism 2 senses that the paper 4 enters the paper feeding area 6, and senses that the paper 4 has arrived at the predetermined position of the electronic device, respectively through a paper feeding sensor (not shown) and a paper output sensor. The paper feeding sensor and the paper output sensor are well-known techniques in the industry, and will not be repeated here.

However, if the paper is creased, especially at the feeding end of the paper, it will be difficult to feed the paper when copying, printing, or transferring the paper, paper jams may occur, or errors in the displayed data may occur.
