Field of the Invention The present invention relates to a paper-making apparatus and a paper feeding system having the paper-feeding mechanism, and specifically to a paper-feeding mechanism relating to a bidirectional feed (four), and having the paper discharge mechanism Two-way paper feed system. [Prior Art] When the length of the recording medium is too long, a problem of overlap of the recording medium is generated. Generally, the recording medium to be printed or scanned overlaps with the end of the recording medium at the end of the recording medium in the two closely arranged paper roller groups, which easily causes the recording medium to stagnate and easily increases the jam when the recording medium is fed. The phenomenon of printing or scanning is not good. See Fig. a, U.S. Patent Specification US 63 〇 7614 bi, a recording medium scanning method. The recording medium is performing double-sided scanning. 'When the recording medium feed end of the second side travels to the rollers 52 and Μ, the direction of rotation of the two rollers makes the recording medium feed end temporarily unable to enter the folder between the two roller groups. Hold the gap and create deflection. Referring to the ib diagram, the thrust of the feed end of the recording medium overcomes the friction between the recording medium and the roller, and the roller reverses to bring the paper head into the clamping gap. However, these designs are prone to the following problem: the feed end of the recording medium after the formation of the second image is stagnant after entering the gap between the two rollers, which reduces the recording medium throughput of the system. . The recording medium for image formation (especially the recording medium to be scanned) is generally used as a non-smooth and smooth recording medium. When the recording medium feed end is easy to generate a card in two closely-rotating and oppositely turning roller groups. Paper phenomenon. 4/19 1375625 , - , _ • t 100 years 〗 〖Revised replacement page on October 31. When the recording medium enters the gap between the two rollers 52 and 54, the deflection will inevitably occur, and the deflection easily affects the figure. The speed of the recording medium like the formation area will lead to the problem of poor image quality. When the recording medium enters the clamping gap of the rollers 54, 52, since the upper recording medium and the lower recording medium travel in the opposite direction, the traveling direction of the upper recording medium is also opposite to the rotation direction of the paper output roller, so that the upper recording medium is dragged. The situation occurs, resulting in an increase in system torque, and the above recording media may be damaged due to drag. In order to solve the above problem, please refer to FIG. 1c. U.S. Patent No. 6,493,060 B2 discloses a movable driven wheel in a paper discharge mechanism, which enables the recording medium to feed the recording medium on the second side when performing double-sided scanning. Before the end travels to the roller 62, the high-load solenoid valve (Solenoid) is used to overcome the spring force of the driven wheel, so that a gap is formed between the two rollers, so that the feed end of the recording medium does not need to be stagnant and there is no deflection. Pass this wheel set. In contrast, expensive high-load solenoid valves must be used in this design, and an additional lifting mechanism is required to move the driven wheels. In addition, the force that makes the roller instantaneously contact makes the surface of the recording medium produce marks of the wheel engagement, which destroys the integrity of the original recording medium. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a paper discharge mechanism that is free from damage to a recording medium, avoids deflection of the recording medium, and does not reduce the amount of recording media throughput of the system. At the same time, it is also free to move the driven wheel in the paper exit roller up and down, and the lifting mechanism that must be provided for this purpose. The paper exit mechanism, also 5/19 1375625. _ October 3, 100, revised the replacement page will not produce traces of the wheel engagement, destroying the integrity of the original recording media. In order to achieve the above object, the present invention adopts the following technical solution: A paper discharge mechanism includes: a paper discharge roller having a D-shaped cross section formed by a rounded portion and a flat portion, and is selectively selectable. The direction is rotated; and a fitting member is disposed at a position relative to the paper discharge roller; wherein the fitting member and the arc portion of the paper discharge roller are used to clamp and convey a recording medium; the fitting member The gap formed between the flat portion of the paper exit roller is sufficient for the recording medium to pass. Another object of the present invention is to provide a bidirectional paper feeding system having the above-described paper discharge mechanism. In order to achieve the above object, the present invention adopts the following technical solution: a bidirectional paper feeding system comprising: a paper feed roller through which a recording medium enters a scanning area through a feeding path; The recording medium can be scanned by a scanning module; a paper feeding roller, the recording medium is discharged out of the scanning area through the paper feeding roller, and enters a discharging path; a returning roller, the recording medium discharged from the scanning area is sent back through the scanning medium The roller enters the scanning area again through the return path; and a paper discharge mechanism, the recording medium enters the paper discharge mechanism through the discharge path, and the paper discharge mechanism comprises: a paper discharge roller having an arc portion and a plane Part of the cross section has a D-shaped structure and can be rotated from the selective direction; and a fitting member is disposed at a position relative to the paper discharge roller; wherein, when the paper discharge roller rotates forward, the arc portion thereof The matching member can be used to clamp and feed the recording medium; when the paper output roller is reversed, the arc portion thereof is clamped with the fitting member and the The discharged recording medium is sent to the return path, and the in-line scanning is performed; and the plane portion of the paper discharge roller and the fitting member form a 6/19 1375625 - . , _ . . . ' 〗 〖October 3 The 曰 repairer replaces the page gap, which allows the recording medium to pass. The invention can avoid the problem that the recording medium of the recording medium collides with the tail end of the recording medium and the tail end of the recording medium when the second side scans the double-sided scanning, thereby reducing the probability of the recording medium jam. In addition, the present invention has no stagnation during the feeding of the recording medium, and a better throughput rate can be obtained. By controlling the rotation direction and time of the D-shaped roller, the invention achieves the paper feeding requirement required for the recording medium to enter and exit the clamping gap and overlap, so that the recording medium does not need to be deflected between the two rollers. Any force pulls to avoid problems caused by poor scanning quality. The application of the paper discharge mechanism facilitates the compactness of the two-way paper feeding system and the use of an recording medium of an excessively long length, and is free from the deficiencies described in the prior art.

The third preferred embodiment of the present invention is shown in the drawings. Please refer to page 6 for the first embodiment. The same is the same as the paper tearing wheel 109#2=, the same 'different 114', and a spring is also connected to the plane plate 113 by means of the elastic n/1 D The r-force ' of the degree position m is automatically compensated for the height of the flat plate 113. The first and second preferred recording medium transmission modes and operations are the same as the plane handle m/span. Among them, it should be noted that the friction coefficient between the media of the media door is smaller than the friction coefficient between the arc portion a and the body, which is convenient for the paper output roller. 〇9 can explain the recording medium, the first - , % _ is sent by the paper exit roller 1〇9:. In the second preferred embodiment, the recording medium P is shown in Fig. 7 to illustrate a fourth preferred embodiment of the present invention. Please refer to the figure θ35 of the fourth superior sinus sorrow 丨#, > 1 , which is basically the same as the preferred embodiment of the younger brother. The different devices (Ρ,^神2) seem to be combined with the return roller 107 (four), and the intermediate roller _ respectively "7 shots; that is, in the loopback path 4 and the discharge path 2, please set at the ===Γ]22. The upstream position of the drawing unit module 05 of the second wheel 103 and the second paper feed roller 04. The fourth preferred recording medium transmission mode and operation and the first preferred embodiment = waste paper machine 2] includes - the first - curved plate 25, to connect the brother of a paper-pressed magazine] 27, the first paper-grained bombs] 27 even 13/19 1375625 - . p-__;- 100 years] 0 months The 31st correction replacement page is attached to the housing of the paper feeding system 100. Similarly, the second paper presser 122 includes a second curved plate 126 and a second platen spring 128 coupled thereto, the second The platen spring 128 is coupled to a housing (not shown) of the paper feeding system 100. It should be noted that the fourth embodiment is used for unidirectional paper feeding, that is, when processing the first side image of the recording medium. The second paper presser 122 in the provided paper feeding system 100 can prevent the recording medium from being skewed. When bidirectional feeding, that is, when processing the second side image of the recording medium The first paper presser 121 of the paper feeding system 100 can prevent the recording medium from being skewed when being fed back. It is to be noted again that the length of the circular arc portion a is to be able to maintain stable scanning and stable transfer of the recording medium cassette. When the clamping gap f of the second paper feed roller 104 is greater than the distance g of the scanning unit module 105 corresponding to the position g of the scanning area, when the trailing end of the recording medium P enters the clamping gap f of the second paper feed roller 104, The paper roller 109 and the paper output driven wheel 110 start to rotate, so that the feed end of the recording medium P can be held and transported, because the tail portion of the recording medium P is scanned, so that stable scanning and stabilization of the recording medium P are maintained. The transfer is necessary. The application of the paper discharge mechanism facilitates the two-way paper feeding system to be more compact, and the recording medium of an excessively long length can be used without the disadvantages described in the prior art.
