Description of the Invention: [Technical Field] The present invention provides a paper feeding mechanism, and more particularly to a paper feeding mechanism capable of correcting the skew condition of a recording medium. [Prior Art] In the design of a facsimile machine, a printer, or even a multifunction machine, in order to meet the demand for a large amount of paper work, there is usually a paper feeding mechanism. The user can place a large amount of paper in the paper feeding mechanism, and the paper feeding mechanism can perform the paper dividing work to feed the paper one by one into the machine for faxing, printing, photocopying, and the like. At present, the high-speed printing machine prevents the paper from being skewed due to the skewing of the paper or the accumulation of tolerances during the conveyance process, so that the printed image seen on the paper is skewed, so Use paper in various ways to eliminate skew of the paper before it enters the print area to reduce the skew of the image. At present, the method for correcting the skew of the paper is mainly divided into two categories: closed loop correction and open loop correction. In the closed loop correction, U.S. Patent No. 5,169,140 and US Pat. No. 5,286,624 disclose the use of a sensor to detect a leading edge. Relative position, and the detection result is transmitted back to the motor, and the skewed paper is corrected by controlling the speed difference between the two motors. However, since the number of parts required for the 1321122 detector plus the motor is large, the cost is high. 'In the control logic, the control logic circuit is complicated because the signal transmitted from the sensor must be processed first, and then the signal is sent to the motor to form a control loop. In addition, in the closed loop correction, there are roughly two ways. In US Pat. No. 6,805,347 B1 and US Pat. No. 5,678,488, it is disclosed that the control of a group of roller sets stops rotating or reversed during the paper feeding process, so that the paper is bucked. ) 'By reducing the rigidity of the paper, the skewed paper can be easily corrected'. However, this method often requires a certain roller group to be reversed and then rotated forward to take some time to correct the paper, thus reducing the paper conveying speed; In another method, it is not necessary to control a certain group of roller groups to stop rotating or reverse in the middle, that is, the feeding operation can be continued, please refer to FIG. 1 and FIG. 2 , and FIG. 1 is a prior art paper feeding mechanism 10 . The paper 12 has not yet been pushed to a schematic diagram of the correction of the skewer n (shutter) 14, and the second diagram is a schematic diagram of the prior art paper feeding mechanism 10 after the paper 12 is pushed to correct the skew gate. The paper feeding mechanism 10 includes a correction skew gate 14 and a The elastic member 16, an input roller 18, a paper feed idler (pinch), a paper feed tray 22', and a paper take-up roller 24. The paper feed tray 22 is used for placing the paper 12'. The paper take-up roller 24 is disposed on the front side of the paper feed tray 22 for rolling the paper 12 toward the paper feed roller 18 and the paper feed idler 20; The roller 18 is used to roll the paper 12; the paper feed idler 20 is used to hold the paper 12 together with the paper feed roller 18; the correction skew gate 14 is mounted on one side of the paper feed roller 18 and the paper feed idler 20, The paper 12 is used to hold the front stop paper 12 together with the paper feed idler 20 by the paper feed roller 18 1321122, thereby correcting the skew of the paper 12; one end of the elastic member 16 is connected to the correction skew gate. 14 and the other end It can be connected to a fixed end (for example, a casing covering the internal components of the paper feeding mechanism 10, etc.) for providing an elastic force to the correction skew gate 14, the elastic member 16 can be a spring, and the correction skew gate 14 can be It is connected to the elastic member 16 in a rotating manner. First, the paper 12 is taken up by the pickup roller 24, passes through the paper feed path of the paper feed tray 22, and hits the correction skew gate 14, and the paper 12 must overcome the elastic force of the elastic member 16 to which the skew gate 14 is attached. The skew gate 14 is pushed to enter the meshing direction of the paper feed roller 18 and the paper feed idler 20. If the paper 12 is in the right state, the paper 12 can enter the meshing roller 18 and the paper feed idler 20 against the elastic force of the elastic member 16 after touching the correction skew gate 14, so that the paper 12 is fed. The roller 18 is clamped together with the paper feed idler 20 and is conveyed into the printing area; if the paper 12 is skewed, the leading edge will first touch the correction skew gate 14, but due to the one side The force of the paper head cannot overcome the elastic force of the elastic member 16. When the paper 12 cannot enter the meshing roller 18 and the paper feed idler 20, it is necessary to wait until the paper 12 is elastically deformed, forcing the paper to be squared. The force of the elastic member 16 overcomes the elastic force of the elastic member 16 and enters the engagement between the paper feed roller 18 and the paper feed idler 20, whereby the paper 12 is held by the paper feed roller 18 and the paper feed idler 20, and is conveyed into the print. region. 1321122 The above-described mechanism for adjusting the skew gate 14 to engage the elastic member 16 has the advantages of lower cost, faster transfer speed, and simple control logic than other methods of correcting skew of the paper, but may result when the paper 12 is light. Even if the paper is squared, the paper 12 cannot effectively overcome the elastic force of the elastic member 16, so that the condition of the skew gate 14 cannot be pushed and the paper jam occurs; or, as shown in Fig. 2, when the paper 12 is After the adjustment of the skew gate 14 is overcome by the elastic force of the elastic member 16, and after the engagement between the paper feed roller 18 and the paper feed idler 20, the tilt angle of the inclined surface is increased due to the correction of the skew gate φ 14 , that is, When the angle between the paper 12 and the correction skew gate 14 becomes small, the clamping force of the skew gate 14 against the paper 12 is too small at this time, so that the paper 12 easily slips off and deviates from the normal paper feed path, causing a problem of paper jam. Therefore, how to find a solution that can reduce the cost and achieve the effect of correcting the skew of the paper is an important task for the design of the current paper feeding mechanism. SUMMARY OF THE INVENTION The present invention provides a paper feeding mechanism that can correct a skew of a recording medium to solve the above problems. The patent application scope of the present invention discloses a paper feeding mechanism capable of correcting a skew condition of a recording medium, comprising a paper feed roller for scrolling a recording medium, and a paper feed idler for holding together with the paper feed roller a recording medium 1321122 body, a correction skew gate mounted on one side of the paper feed roller and the paper feed idler, the correction skew gate includes a resilient pad for the recording medium to be fed by the paper feed roller The paper feed idler co-clamps the front stop gear to thereby correct the skew of the recording medium, and an elastic member is coupled to the correction skew gate for providing an elastic force to the correction skew gate, the correction skew gate It is rotatably connected to the elastic member. [Embodiment] Please refer to FIG. 3, FIG. 4, and FIG. 5. FIG. 3 is a schematic view of a paper feeding mechanism 50 according to the present invention, and FIGS. 4 and 5 show that some components of the paper feeding mechanism 50 are different. Schematic diagram of the perspective of the perspective. The paper feeding mechanism 50 can be applied to a printer, a facsimile machine, a multifunction printer, etc., and the user can put the recording medium 52 into the paper feeding mechanism 50, and the paper feeding mechanism 50 can perform the paper dividing work. The recording medium 52 is fed into the corresponding machine one by one to perform operations such as printing, faxing, photocopying, etc., wherein the recording medium 52 can be a paper or a slide film or the like. The paper feeding mechanism 50 includes at least one correction skew gate 54, at least one elastic member 56, at least one paper feed roller 58, at least one paper feed idler 60, a paper feed tray 62, and a pickup roller 64. The paper feed tray 62 is used for arranging the recording medium 52; the paper take-up roller 64 is disposed on the front side of the paper feed tray 62 for scrolling the recording medium 52 toward the paper feed roller 58 and the paper feed idler 60; The paper feed roller 58 is used to scroll the recording medium 52; the paper feed idler 60 is used to hold the recording medium 52 together with the paper feed roller 58. The plate positive skew gate 54 is attached to the paper feed roller 58 and the paper feed idler. On one side of the 6 ,, the correction slant gate 54 includes a baffle 66, and a smashing shackle 68' is disposed on the baffle 66, that is, the impact surface hit by the recording medium 52 is used for the recording medium 52. The paper feed roller 58 and the paper feed idler 60 together hold the front stop recording medium 52, thereby correcting the condition of the recording medium 52 being skewed. 'Flexibility profile 68 can be made of polyethylene (p〇iyethyiene, pe) The spring element is composed of a sponge material; one end of the elastic member 56 is connected to the correction skew gate 54 and the other end is connected to a fixed luer end (for example, a shell covering the inner component of the paper feeding mechanism 50, etc.) ), is used to provide an elastic force to the correction skew gate 54, and the elastic member 56 is It is a spring, and the correction skew gate 54 is rotatably coupled to the elastic member 56. First, the recording medium 52 is picked up by the pickup roller 64, and passes through the paper feed path ' of the paper feed tray 62 to strike the elastic spacer 68 provided on the shutter 66 of the correction skew gate 64. The recording medium 52 must overcome the correction skew. The elastic force of the elastic member 56 to which the door 54 is attached can push the deflector 66 of the skew opening 54 to enter the spray of the paper feed roller 58 and the paper feed idler 60. If the recording medium 52 is in the correct state, the recording medium 52 can enter the meshing roller 58 and the paper feed idler 60 at the meshing force against the elastic force of the elastic member 56 after touching the elastic spacer 68 of the correction skew gate 54. Therefore, the recording medium 52 is sandwiched by the paper feed roller 58 and the paper feed idler 60, and is transported into the printing area. If the recording medium 52 is in a skewed state, the unilateral leading edge of the recording medium 52 is first touched. The elastic pad 68 provided on the baffle plate 66 of the skew gate 54 is fixed by the 13^1122, but at this time, the force of the one-sided leading edge of the recording medium 52 cannot overcome the elastic force of the elastic member 56 for a time, and it is necessary to wait for the recording medium. After the elastic deformation of 52, the leading edge of the recording medium 52 is forced to be squared to have sufficient force to overcome the elastic force of the elastic member 56. However, in this process, since the elastic pad 68 is a deformable elastic material (such as a polyethylene foam material or a sponge material), the recording medium 52 can be applied with an elastic gasket 68 - pressure to deform the elastic lining 68. Therefore, the elastic lining 68 can provide more holding force and friction to hold the leading edge of the recording medium 52 at a certain point on the impact surface of the elastic pad φ 68, and wait until the leading edge of the recording medium 52 is aligned. The recording medium 52 can overcome the elastic force of the elastic member 56 and enter the meshing direction of the paper feed roller 58 and the paper feed idler 60, whereby the recording medium 52 is held by the paper feed roller 58 and the paper feed idler 60 together. Transfer into the print area. When the recording medium 52 pushes the correction skew valve 54 against the elastic force of the elastic member 56, and enters the meshing roller 58 and the paper feed idler 60, the correction skew gate 54 is rotated to tilt the slope. The angle becomes larger, that is, the angle between the recording medium 52 and the correction skew gate 54 becomes smaller. Referring to FIG. 6, FIG. 6 is a schematic view of the paper feeding mechanism 50 of the present invention after the recording medium 52 is pushed to correct the skew gate 54, because the elasticity The spacer 68 can provide more gripping force and friction to hold the leading edge of the recording medium 52 at a certain point on the impact surface of the elastic lining 68, thereby supporting the leading edge of the recording medium 52, so that the recording medium 52 does not slip off. And deviate from the normal paper feeding path, and 12 1321122 i ' can effectively solve the problem of paper jam. Compared with the prior art, the paper feeding mechanism of the present invention can effectively correct the skew condition of the recording medium by using the design of the elastic pad on the correction skew gate, and the mechanism design can increase the correction of the skew gate holding the recording medium. The clamping force and the friction force can effectively amplify the applicable range of the original elastic component, so that the lighter recording medium can be applied without the problem of paper jam, so the paper feeding mechanism of the present invention has Low cost, faster transfer speed, Φ simple control logic, and the advantages of jamming problems. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the patent application of the present invention should fall within the scope of the present invention.
