Description

Paper separation module and business machine using this paper separation module

technical field

The invention relates to a paper-separating module and a business machine, in particular to a paper-separating module and a business machine which have a stable paper-separating effect and are not easy to jam.

Background technique

With the development of science and technology and the interconnection of human networks, various electronic and electrical products have become indispensable tools in daily life. For example, when working, the commonly used machines in the office include computers, printers, fax machines, photocopiers, etc. Among them, the work efficiency of printers, photocopiers, and fax machines that use paper will be affected. Influence of feeding function.

Taking the current business machine with both photocopying and printing functions as an example, an automatic paper feeding device is installed on it to drive the blank paper carried into the business machine for printing. Before printing, the user places the paper at the paper feeding device (such as a paper tray). When printing, the paper is conveyed in the business machine through the paper feeding device, and the printing device forms images on the paper.

FIG. 1 is a partial schematic diagram of an existing business machine, and FIG. 2 is a schematic diagram of the paper separating module in FIG. 1 . Please refer to FIG. 1 and FIG. 2 at the same time. In the business machine 100, the base plate 101 is used to carry paper, and the roller 150 arranged above the base plate 101 is used to drive the paper forward, and the paper separation module 103 arranged on the base plate 101 separates the paper. Separate one by one.

In detail, the elastic element 103a of the paper separating module 103 is a cantilever beam, and the width and thickness of the elastic element are the same from the connecting end 103b to the free end 103c. With such a structural design, the paper separating module 103 is easily affected by the amount of paper in the paper tray. Furthermore, since the connecting end 103b is connected to the main body 103d of the paper separating module 103, the rigidity of the connecting end 103b is greater than the rigidity of the free end 103c. When the paper 105 is transported, although the paper 105 exerts the same force on the connecting end 103b and the free end 103c, the deformation of the connecting end 103b is smaller than that of the free end 103c. On the other hand, when there are fewer papers in the paper-receiving box, a larger force is needed to deform the elastic element 103a of the paper-separating module, so the leading edge of the paper 105 is easier to deform. damaged.
