Method for sharing scanning and printing path of multifunction printer and device therefor

Abstract

The invention discloses a method for sharing a scanning and printing path of a multifunction printer and a device therefor. The method mainly comprises that: file paper to be scanned and printing paper are respectively accommodated in a first feeding groove and a second feeding groove which are provided with external openings and adjacently parallel; a first limit component is arranged beside theoutside of the paper output end of the first feeding groove; a second limit component is arranged beside the outside of the paper output end of the second feeding groove; a shared pivoted component is arranged between the first limit component and the second limit component, and can be controlled to selectively push against and link with the first limit component and the second limit component soas to clamp and transfer the file paper or the paper in the first feeding groove and the second feeding groove; and a power source drives the first limit component and the second limit component or the shared pivoted component to respectively transfer the file paper or the printing paper in the first feeding groove and the second feeding groove for scanning or printing.

Description

Technical field: [0001] The present invention relates to a scanning and printing path sharing method and device of a multifunctional business machine, in particular to a shared feeding power acting direction that can be switched as required, so as to achieve the purpose of sharing scanning and printing conveying power devices. Background technique: [0002] Most of the existing traditional multi-function printer structures with scanning and printing functions are designed to separate the printing module and the scanning module, and each has a different paper picking (scanning document) path and related feeding components, but in fact, the The parts used in the two modules have the same function, and the repeated use of the same components will not only increase the cost and be uneconomical, but also increase the overall volume, which is not conducive to the demands of miniaturization and refinement of products. [0003] In order to solve the above problems, there is an inven...

Problems solved by technology

[0004] 1. Because the documents in the automatic document feeding area and the paper in the automatic paper feeding area are in an overlapping state (not completely separated) beside the carrying roller, but the pressure plate is used to produce different degrees of support. The file or paper corresponds to the correct paper feeding position, and then cooperates with the drive of the carrying roller to complete the feeding (or file) action. In this way, it is very susceptible to differences in different objective conditions (such as: paper surface friction, carrying Roller surface wear, spring fatigue, etc.) affect the accuracy and fineness of its feeding, which is a lack of application

[0005] 2. Furthermore, since (as shown in the figure) the documents in the automatic document feeding area are set between the paper and the carrying rollers in the automatic document feeding area, in use, if there are a large number of scanned documents and once they enter the document In the scanning state, the document in the automatic document feeding area must be completely scanned and sent out before continuing to print (feed the paper from the automatic paper feeding area). Pre-memory printed content), resulting in an increase in the overall cost, which is not conducive to the improvement of product competitiveness
