The specific embodiment
Please refer to Fig. 1, it illustrates the partial schematic diagram of the image processor of a kind of paper feed mechanism with preferred embodiment of the present invention.Image processor 10 has body 50, image process area 50a, and image processing module 52 is positioned at image process area 50a.Image processor 10 can be the one scan instrument, and then image processing module 52 is scan modules; Image processor 10 also can be a chopping machine, and then image processing module 52 is print modules.Image processor 10 is to be that example is done explanation with the scanner in the present embodiment.Paper feed mechanism 100 is arranged on the body 50, in order to paper (not illustrating) is fed to image process area 50a.Paper feed mechanism 100 comprises carrying platform 120, in order to bearing paper.Lead paper assembly 130 and for example be fixing projection, be arranged on the side of carrying platform 120, advance in order to guide paper.Paper feed unit 140 is arranged at the paper feed end of carrying platform 120, and in order to contact and drive paper, paper feed unit 140 for example is a rubber roll in the present embodiment.Friction impedance component 150 is arranged at a side of paper feed unit 140, leads another side that paper assembly 130 is positioned at paper feed unit 140.Friction impedance component 150 is in order to the friction force between the surface that increases paper and carrying platform 120, contacts during paper is driven by paper feed unit 140 and leads paper assembly 130.In the present embodiment, friction impedance component 150 is preferably contiguous paper feed unit 140 and is provided with.In addition, though paper feed mechanism 100 is used for scanner, also can be installed in chopping machine, duplicator, facsimile apparatus or multifunctional paper feeding machine (multi-function product, MFP) on.So long as can set up the office electronic equipment of automatic paper feeder (automatic document feeder), can use embodiments of the invention.
Please refer to Fig. 2, it illustrates the partial schematic diagram of the paper feed mechanism of Fig. 1 in another angle.As shown in Figure 2, friction impedance component 150 can be suppressor of mono-, or the friction shim with great friction coefficient, friction impedance component 150 comprises suppressor 152 and friction shim 154 simultaneously in the present embodiment, can be considered the first friction impedance component and the second friction impedance component.Please refer to Fig. 3, it illustrates the friction impedance component of Fig. 2 and the lateral plan of loam cake.In the present embodiment, paper feed mechanism 100 comprises that more loam cake 105 is arranged at the offside of carrying platform 120, suppressor 152 is to be arranged at loam cake 105 and to protrude from loam cake 105 towards paper feed carrying platform 120 with shell fragment 152b, with the friction force between the surface that increases paper and carrying platform 120.In the present embodiment, suppressor 152 is made of roller 152a and shell fragment 152b, and roller 152a is arranged on the shell fragment 152b, and shell fragment 152b is arranged at loam cake 105 and provides roller 152a in order to pressure-formed elastic force.Roller 152a also can be idle pulley (idle roller), perhaps only provides friction force with shell fragment.Friction shim 154 is arranged on the paper feed mechanism body 110, together contacts paper and provides paper another friction force with the suppressor 152 of top.In addition, friction impedance component 150 can be regional a formation by carrying platform 120, surface with respect to extra-regional carrying platform 120, the surface of the carrying platform 120 in the zone has high friction coefficient, and the surface that for example will be close to the carrying platform 120 of paper feed unit 140 is processed into a rough surface through frosted.But technology of the present invention is not limited thereto, and friction shim 154 also can up move and be arranged on the carrying platform 120.With Fig. 1 is example, is bench mark with the upper right corner of paper feed unit 140, marks off area I and area I I.Friction shim 154 can be arranged on the area I on the carrying platform 120, also can be arranged at the area I I on the carrying platform 120; Same, also can corresponding friction shim 154 be arranged on the top of area I or area I I as the shell fragment of another friction impedance component or roller.In addition, also can be provided with two groups simultaneously in area I and area I I, or two groups of above friction impedance components 150.As long as paper feed unit 140 is arranged on friction impedance component 150 and leads between the paper assembly 130, can reach the effect of adjusting paper position.The friction impedance component also can only use suppressor 152 or friction shim 154.
In addition, as shown in Figure 1, image processor 10 comprises that more second leads paper assembly 160 and be arranged at movably on the carrying platform 120 with respect to leading paper assembly 130, is positioned at the same side of paper feed unit 140 with friction impedance component 150, advances in order to the guiding paper.In the present embodiment, second to lead paper assembly 160 be can being provided with respect to the mode that carrying platform 120 slides, therefore can be according to the size adjusting limited field of paper.
When paper was driven by paper feed unit 140, friction impedance component 150 provided friction force.If being arranged, width leads the paper of the distance of 160 of paper assemblies less than leading paper assembly 130 and second, in the paper traveling process towards the direction that is not subjected to leading 130 restrictions of paper assembly when crooked, the friction force that friction impedance component 150 provides can be adjusted paper, and paper is offset towards the direction of leading paper assembly 130 in traveling process.Since lead paper assembly 130 can contact paper with the restriction paper moving range, so paper normally state feed-in image processing module 52 carry out subsequent treatment.
Please refer to Fig. 2, paper feed mechanism 100 comprises that more branch paper packing 170 correspondences are arranged at 140 tops, paper feed unit, when two pieces of paper are opened overlapping together by 140 drives of paper feed unit, divides paper packing 170 in order to contact top paper to increase friction force.Because friction force between branch paper packing 170 and the top paper and the friction force between paper feed unit 140 and the following paper respectively greater than the friction force between two paper, make two pieces of paper open and are separated, and reach the function of separation.
The disclosed paper feed mechanism of the above embodiment of the present invention and use its image processor, be to provide the friction impedance component to increase friction force, when paper or file are crooked toward the direction that is not restricted, friction force can be got back to suitable position with paper or file correction, make paper or file with the correct status feed-in, prevent operational mistake.
In sum, though the present invention discloses as above with preferred embodiment, so it is not in order to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when doing various changes and retouching.Therefore, protection scope of the present invention is when looking being as the criterion that accompanying Claim book scope defined.
