Paper stopping mechanism and automatic paper feed device using same

Abstract

The invention relates to a paper stopping mechanism and an automatic paper feed device using the same. The automatic paper feed device is provided with a paper feed plate and a paper extraction roller wheel. The paper stopping mechanism comprises a guide element, a paper stopping element and a guide groove, wherein the guide element is provided with a shaft sleeve part and an extending arm, wherein the shaft sleeve part is sleeved on the shaft part of the paper extraction roller wheel; the paper stopping element is provided with a paper stopping part, an inserted pin and a supported part, wherein the extending arm of the guide element upwards supports against the supported part of the paper stopping element; and the guide groove is used for containing the inserted pin of the paper stopping element. Thus when the paper extraction roller wheel is close to the paper feed plate, the guide element linked with the paper extraction roller wheel through the shaft sleeve part can drive the inserted pin of the paper stopping element to translate and rotate in the guide groove so that paper can be smoothly fed because the paper stopping part of the paper stopping element no longer obstructs the front edge of the paper positioned on the paper feed plate.

Description

technical field [0001] The invention relates to an automatic paper feeding device, in particular to a paper blocking mechanism in the automatic paper feeding device. Background technique [0002] With the rapid advancement of electronic technology, all routine work in the office today is closely related to business machines such as photocopiers, fax machines, printers, and scanners. Therefore, these business machines have become indispensable information equipment in the office. However, because many business machines often occupy too much space, and even because the utilization rate of each business machine is not the same, it usually results that although some types of business machines have low utilization rates, they still have to be purchased to meet occasional problems. required situation. [0003] In order to solve these problems and conform to the trend of "miniaturization" and "functional integration" of today's information products, a Multi Function Peripheral (MF...

AI Technical Summary

Problems solved by technology

[0006] However, the disadvantage of the above-mentioned traditional paper stop mechanism is that if the cover of the automatic paper feeder is opened due to troubleshooting, when the cover returns to its original position, it may cause paper insertion and cause the paper to be broken. After the paper is taken out, it is reset by the weight method, and the problem of inaccurate movement often occurs due to the counterweight design or the burr of the rotating shaft caused by the production process.
