Description
- 1. Field of the Invention
- The present invention relates to a paper-feeding mechanism, and more particularly, to a paper-feeding mechanism capable of adjusting skew print media.
- 2. Description of the Prior Art
- When printing to paper with a fax machine, a printer, or a multi-function product, a paper-feeding mechanism is utilized for feeding paper one sheet at a time into machines so as to proceed to faxes, printouts, copies, and so on. For preventing skew images on print media, several methods are applied to get rid of skew feed of print media due to skew position or tolerance.
- There are two kinds of methods for adjusting the skew print media. One is a close loop deskew method, and the other is an open loop deskew method. For the close loop deskew method, U.S Pat. No. 5,169,140 and U.S Pat. No. 5,278,624 disclose a method for detecting relative position of the leading edge of the print media by sensors and transmitting a detecting result to motors. The skew print media can be adjusted by controlling speed of the two motors. However it not only increases cost due to many components of the sensors and the motors but also complicates the control circuit for processing signals transmitted from the sensors and transmitting corresponding signals to the motors.
- There are two kinds of manners for adjusting the skew print media with the open loop deskew method. U.S Pat. No. 6,805,347B1 and U.S Pat. No. 5,678,488 disclose a method for making the print media buckle to reduce rigidity of the print media so as to adjust the print media easily by controlling a gear set to stop rotating or to reverse. However it reduces transmission speed of the print media because it takes time to control the gear set to reverse first and to forward then. There is no need to stop or reverse the gear set halfway and the paper-feeding process continues with the other manner. Please refer to
FIG. 1 andFIG. 2 .FIG. 1 is a diagram of a paper-feeding mechanism 10 when aprint medium 12 has not pushed adeskew shutter 14 in the prior art.FIG. 2 is a diagram of the paper-feeding mechanism 10 when theprint medium 12 has pushed thedeskew shutter 14 in the prior art. The paper-feeding mechanism 10 includes thedeskew shutter 14, anelastic component 16, aninput roller 18, apinch input roller 20, apaper tray 22, and apickup roller 24. Thepaper tray 22 is for positioning theprint medium 12. Thepickup roller 24 is installed in front of thepaper tray 22 for picking up theprint medium 12 to theinput roller 18 and thepinch input roller 20. Theinput roller 18 is for picking up theprint medium 12. Thepinch input roller 20 is for nipping theprint medium 12 with theinput roller 18. Thedeskew shutter 14 is installed on a side of theinput roller 18 and thepinch input roller 20 for blocking theprint medium 12 before theprint medium 12 is nipped by theinput roller 18 and thepinch input roller 20 so as to adjust theskew print medium 12. An end of theelastic component 16 is connected to thedeskew shutter 14, and the other end of theelastic component 16 is connected to a fixed end, such as a housing for covering internal components of the paper-feeding mechanism 10. Theelastic component 16 provides an elastic force to thedeskew shutter 14. Thedeskew shutter 14 is connected to theelastic component 16 in a rotatable manner. Theelastic component 16 can be a spring. - First the
print medium 12 is picked up by thepickup roller 24, passes through a paper-feeding route of thepaper tray 22, and hits thedeskew shutter 14. Theprint medium 12 has to overcome the elastic force provided by theelastic component 16 connected to thedeskew shutter 14 so that theprint medium 12 is capable of pushing thedeskew shutter 14 to enter nip location of theinput roller 18 and thepinch input roller 20. If theprint medium 12 is positioned exactly, theprint medium 12 can overcome the elastic force provided by theelastic component 16 so that theprint medium 12 is capable of pushing thedeskew shutter 14 to enter nip location of theinput roller 18 and thepinch input roller 20. Then theprint medium 12 is nipped by theinput roller 18 and thepinch input roller 20 together and transmitted to a print area. If theprint medium 12 is skew, one leading edge of theprint medium 12 hits thedeskew shutter 14 first but the leading edge of theprint medium 12 can not overcome the elastic force provided by theelastic component 16 so that theprint medium 12 is not capable of pushing thedeskew shutter 14 to enter nip location of theinput roller 18 and thepinch input roller 20 on the instant. After theprint medium 12 deforms so that two leading edges of theprint medium 12 hit thedeskew shutter 14, theprint medium 12 can overcome the elastic force provided by theelastic component 16 so that theprint medium 12 is capable of pushing thedeskew shutter 14 to enter nip location of theinput roller 18 and thepinch input roller 20. Then theprint medium 12 is nipped by theinput roller 18 and thepinch input roller 20 together and transmitted to the print area. - Compared with other methods for adjusting the skew print medium, the paper-
feeding mechanism 10 with thedeskew shutter 14 and theelastic component 16 has advantages of low cost, fast transmission speed, and a simple control circuit. However it is possible that theprint medium 12 still can not overcome the elastic force provided by theelastic component 16 so that theprint medium 12 is not capable of pushing thedeskew shutter 14 after theprint medium 12 deforms so that two leading edges of theprint medium 12 hit thedeskew shutter 14 due to the light print medium. It causes a paper jam problem. Furthermore, as shown inFIG. 2 , when theprint medium 12 overcomes the elastic force provided by theelastic component 16 to push thedeskew shutter 14 and to enter nip location of theinput roller 18 and thepinch input roller 20, theprint medium 12 strays from a normal paper-feeding route easily because of reducing included angle between theprint medium 12 and thedeskew shutter 14 when thedeskew shutter 14 rotates so as to reduce a holding force applied on theprint medium 12 by thedeskew shutter 14. It also causes a paper jam problem. There is a need to find out a solution for both reducing cost and adjusting the skew print medium effectively. - It is therefore a primary objective of the claimed invention to provide a paper-feeding mechanism capable of adjusting skew print media for solving the above-mentioned problem.
- According to the claimed invention, a paper-feeding mechanism includes an input roller for picking up a print medium, a pinch input roller for nipping the print medium with the input roller, and a deskew shutter installed on a side of the input roller and the pinch input roller. The deskew shutter includes a flexible pad for blocking the print medium before the print medium is nipped by the input roller and the pinch input roller so as to adjust the skew print medium. The paper-feeding mechanism further includes an elastic component connected to the deskew shutter for providing an elastic force to the deskew shutter. The deskew shutter is connected to the elastic component in a rotatable manner.
- These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

FIG. 3 andFIG. 4 .FIG. 3 is a diagram of a paper-feeding mechanism 50 of the present invention.FIG. 4 andFIG. 5 are schematic drawings of part components of the paper-feeding mechanism 50 at different view angles of the present invention. The paper-feedingmechanism 50 can be utilized in a printer, a fax, a multifunction product (MFP), and so on. The paper-feedingmechanism 50 is utilized for feeding aprint medium 52, such as paper or transparency, one sheet at a time into machines so as to proceed to faxes, printouts, copies, and so on. The paper-feedingmechanism 50 further includes adeskew shutter 54, at least oneelastic component 56, at least oneinput roller 58, at least onepinch input roller 60, apaper tray 62, and apickup roller 64. Thepaper tray 62 is for positioning theprint medium 52. Thepickup roller 64 is installed in front of thepaper tray 62 for picking up theprint medium 52 to theinput roller 58 and thepinch input roller 60. Theinput roller 58 is for picking up theprint medium 52. Thepinch input roller 60 is for nipping theprint medium 52 with theinput roller 58. Thedeskew shutter 54 is installed on a side of theinput roller 58 and thepinch input roller 60. Thedeskew shutter 54 includes abaffle 66, and aflexible pad 68 disposed on thebaffle 66 and on an impact surface of theprint medium 52 for blocking theprint medium 52 before theprint medium 52 is nipped by theinput roller 58 and thepinch input roller 60 so as to adjust theskew print medium 52. Theflexible pad 68 can be made of polyethylene (PE) forming material or sponge material. An end of theelastic component 56 is connected to thedeskew shutter 54, and the other end of theelastic component 56 is connected to a fixed end, such as a housing for covering internal components of the paper-feedingmechanism 50. Theelastic component 56 provides an elastic force to thedeskew shutter 54. Thedeskew shutter 54 is connected to theelastic component 56 in a rotatable manner. Theelastic component 56 can be a spring. - First the
print medium 52 is picked up by thepickup roller 64, passes through a paper-feeding route of thepaper tray 62, and hits theflexible pad 68 disposed on thebaffle 66 of thedeskew shutter 54. Theprint medium 52 has to overcome the elastic force provided by theelastic component 56 connected to thedeskew shutter 54 so that theprint medium 52 is capable of pushing thebaffle 66 of thedeskew shutter 54 to enter nip location of theinput roller 58 and thepinch input roller 60. If theprint medium 52 is positioned exactly, theprint medium 52 can overcome the elastic force provided by theelastic component 56 so that theprint medium 52 is capable of pushing theflexible pad 68 disposed on thebaffle 66 of thedeskew shutter 54 to enter nip location of theinput roller 58 and thepinch input roller 60. Then theprint medium 52 is nipped by theinput roller 58 and thepinch input roller 60 together and transmitted to a print area. If theprint medium 52 is skew, one leading edge of theprint medium 52 hits theflexible pad 68 disposed on thebaffle 66 of thedeskew shutter 54 first but the leading edge of theprint medium 52 can not overcome the elastic force provided by theelastic component 56 on the instant. After theprint medium 52 deforms so that two leading edges of theprint medium 52 hit thedeskew shutter 54, theprint medium 52 can overcome the elastic force provided by theelastic component 56. Because theflexible pad 68 is made of deformable and flexible material, such as polyethylene forming material or sponge material. A deformed depression of theflexible pad 68 is formed by a pressure force provided by theprint medium 52. Theflexible pad 68 can provide more holding force and friction force to hold the leading edge of theprint medium 52 on the impact surface of theflexible pad 68. When the two leading edges of theprint medium 52 are positioned in alignment, theprint medium 52 can overcome the elastic force provided by theelastic component 56 so that theprint medium 52 is capable of pushing thedeskew shutter 54 to enter nip location of theinput roller 58 and thepinch input roller 60. Then theprint medium 52 is nipped by theinput roller 58 and thepinch input roller 60 together and transmitted to the print area. - When the
print medium 52 overcomes the elastic force provided by theelastic component 56 to push thedeskew shutter 54 and to enter nip location of theinput roller 58 and thepinch input roller 60, thedeskew shutter 54 rotates and an inclined angle of thedeskew shutter 54 increases, that is, an included angle between theprint medium 52 and thedeskew shutter 54 decreases. Please refer toFIG. 6 .FIG. 6 is a diagram of the paper-feedingmechanism 50 when theprint medium 52 has pushed thedeskew shutter 54 of the present invention. Because theflexible pad 68 can provide more holding force and friction force to hold the leading edge of theprint medium 52 on the impact surface of theflexible pad 68, theprint medium 52 can not stray from a normal paper-feeding route. That is, theflexible pad 68 can prevent theprint medium 52 from dropping from thedeskew shutter 54 and avoids a paper jam situation. - In contrast to the conventional paper-feeding mechanism, the paper-feeding mechanism of the present invention disposes the flexible pad on the deskew shutter for adjusting the skew print medium effectively. This mechanism design increases holding force and friction force to hold the print medium by the deskew shutter. It can increase a suitable range of the elastic component solve the problem of paper jam due to light print medium. The paper-feeding mechanism of the present invention has advantages of low cost, fast transmission speed, a simple control circuit, and avoiding paper jam.
- Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
