Problems solved by technology
Therefore, the paper will be subjected to a large force, which will easily cause the paper to be damaged
At the same time, the excessive resistance of the paper separator will easily cause the paper picking roller to run idly
[0008] To sum up, if the paper separation distance is too large or too small, the effect of paper separation will be affected, and accidents such as paper jams or paper damage will occur. However, whether it is figure 1 or image 3 The paper feeding mechanism and the size of the paper separation distance will obviously change with the number of papers placed in the paper slots 12 and 22, that is, it is impossible to maintain a stable and consistent paper separation effect

Embodiment Construction
[0026] In the following description, in order to achieve the consistency of the technical explanation of the present invention, in different embodiments, if there are components with the same function but slightly different shapes, they are still represented by the same names and figure numbers.
[0027] Please refer to Figure 4A As shown in FIG. 4B , it is a side view of a preferred embodiment of the paper feeding mechanism of the present invention under full paper state and empty paper state. As shown in the figure, the paper feeding mechanism can be externally attached to a business machine (not shown) or a printing device (not shown), or directly installed in a business machine or a printing device. The paper feeding mechanism includes a paper separating board 104 , a paper feeding tray 102 , a paper picking roller 109 and a paper picking arm 108 . Wherein, the paper separation board 104 is aligned with the paper feeding port A of the business machine, and on the upper s...

The paper feeding mechanism includes one paper separating board, one paper feeding pallet, one paper taking roller, one paper taking arm and one elastic member. The paper feeding pallet obliquely on the paper separating board support paper; the paper taking roller in front of the paper feeding pallet rolls paper downwards for feeding paper through the paper separating board one sheet by one sheet; the paper taking arm below the paper separating board drives the connected paper taking roller; and the elastic member connected to the paper taking arm provides one force to the paper taking roller for contact to paper and regulate the distance between the paper taking roller and the paper feeding pallet dynamically for matching the thickness of the paper.
Description
technical field [0001] The invention relates to a paper feeding mechanism and a printing device using the paper feeding mechanism, in particular to a paper feeding mechanism with fixed paper feeding rollers to drive documents and a printing device using the paper feeding mechanism. Background technique [0002] In the design of facsimile machines, printers, and even multifunctional business machines, in order to meet the requirements of a large number of paper jobs, there is usually a paper feeding mechanism. The user can put a large amount of paper into the paper feeding mechanism, and the paper feeding mechanism can separate the paper and feed the paper into the machine one by one for faxing, printing, photocopying and other operations. [0003] Please refer to figure 1 As shown, it is a schematic diagram of a typical paper feeding mechanism. As shown in the figure, the paper feeding mechanism 10 has a paper slot 12 , a paper separator 14 , a rotating shaft 16 , a paper ...
