Next, the structure to fuser 31 is elaborated.Fig. 3 is the approximate three-dimensional map of the fuser 31 in the image processing system 10 that relates to of expression the utility model, Fig. 4 is the partial exploded view of the fuser 31 in the image processing system 10 that relates to of expression the utility model, and Fig. 5 is the schematic diagram of the fixing roller 310 that relates to of expression the utility model.
As shown in Figure 3, Figure 4, the fuser 31 that relates to of the utility model is made of fixing roller 310, backer roll 311, conveyer 312, C ring 313, lining (bush) 314.
Fixing roller 310 has the metallicity such as aluminium, iron etc., handles so that toner can be thereon not bonding by two-sided coating the (coating) to fixing roller 310.Fixing roller 310 comprises the U-lag 310a of conduct first slot part of accepting conveyer 312 drivings and the groove 310b of conduct second slot part that restriction fixing roller 310 moves vertically at the roller end face.
And fixing roller 310 is formed with the 310c(of pull and stretch portion with reference to Fig. 5 at U-lag 310a), the 310c of pull and stretch portion also can be called as extension, strengthening section etc.In example shown in Figure 5, sense of rotation (arrow m direction among Fig. 5) along fixing roller, the 310c of this pull and stretch portion is not formed on the whole inner surface place of U-lag 310a, be not formed on the whole circumference of fixing roller 310 yet, but only be formed on the side (with reference to a side of the arrow n indication among Fig. 5) that device 312 is exerted pressure that is transmitted of U-lag 310a.
More specifically, in example shown in Figure 5, the 310c of pull and stretch portion is made up of two parts.First is shown in Figure 5 for rectilinear form along the side formation that device 312 is exerted pressure in sense of rotation that is transmitted of U-lag 310a; Second portion forms along the trench bottom of U-lag 310a, be curved shape shown in 5, and this curved shape can be for the part of circular, oval, parabola shaped, hyperbola etc., as long as can be well chimeric with conveyer 312.By the second portion of the 310c of pull and stretch portion is set, guaranteed can not occur crackle as shown in Figure 1.
In example shown in Figure 5, the 310c of pull and stretch portion is formed along the inner surface of U-lag 310a and extends to circumferencial direction.Its development length without limits, as long as can reach the purpose that enlarges with the contact area of conveyer 312.The 310c of pull and stretch portion can be integrally formed with an end of fixing roller 310, also may be separately formed.
Compare with the situation that forms the pull and stretch 310c of portion at the complete cycle (whole circumference) of fixing roller 310, only being transmitted shape that a side that device 312 exerts pressure arranges the 310c of pull and stretch portion and can reducing processing loss to fixing roller 310 of U-lag 310a, and be easy to keep the circularity (cylindrical direction) of the fixing roller 310 after the processing.By forming the pull and stretch 310c of portion, namely carry out pull and stretch processing, thereby the rigidity of the surface of contact between fixing roller 310 and the conveyer 312 is improved, and contact area also becomes extensively, so can relax the concentrated of stress.Thus, can form the tectosome that crackle etc. be difficult for to take place.
Backer roll 311 is be used to making toner be fixed on parts on the thin slice P, and it is set to fixing roller 310 opposed, and backer roll 311 is carried thin slice P with fixing roller 310 clampings.In addition, in order to ensure adding pressure surface, backer roll 311 is with the metallicity modular construction that coiling rubber forms on axle.
Conveyer 312 for example can be implemented as transmission gear etc.In this example, conveyer 312 is enclosed within on the fixing roller 310, and it is that mask is equipped with projection 312a within it, and is chimeric by projection 312a and U-lag 310a be used to the drive transmission part that makes fixing roller 310 rotations, thereby transmits driving to fixing roller 310.The material of conveyer 312 can be used heat stable resin or metal.
C ring 313 is axial parts of restriction fixing roller 310, the chimeric use of groove 310b of itself and fixing roller 310.
Lining 314 is as the bearing of fixing roller 310 and backer roll 311 and play a role, fixedly fixing roller 310 and backer roll 311.
In sum, by a side that only applies at the pressure of conveyer 312 310c of pull and stretch portion is set, thereby compare with the situation that forms the pull and stretch 310c of portion at the complete cycle of U-lag 310a, can reduce the processing loss to fixing roller 310, and be easy to keep the circularity of the fixing roller 310 after the processing.And, owing to be formed with the 310c of pull and stretch portion, thus the rigidity of the surface of contact between fixing roller 310 and the conveyer 312 is improved, and contact area also becomes extensively, so can relax concentrating of stress, is difficult for taking place crackle etc.
Certainly, the 310c of pull and stretch portion also can only be provided with first mentioned above, perhaps, described pull and stretch portion only is formed on a side place in the downstream on the sense of rotation that is positioned at described fixing roller of described U-lag, perhaps, the 310c of pull and stretch portion also can be arranged on the whole inner surface of U-lag 310a, and is not limited only to be arranged on the side that the pressure of conveyer 312 applies.In this case, similarly, also can improve the rigidity of the surface of contact between fixing roller 310 and the conveyer 312, contact area also becomes extensively, so can relax concentrating of stress, is difficult for taking place crackle etc.
In addition, though figure 5 illustrates the example of the 310c of pull and stretch portion, as long as but the rigidity that can make the surface of contact between fixing roller 310 and the conveyer 312 is improved, contact area also becomes extensively, can relax concentrating of stress, then it can be arbitrary form.
In addition, U-lag 310a and projection 312a are chimeric also just to drive an example that transmits, as long as being transmitted, 312 pairs of fixing rollers of conveyer 310 drive, and then also can be other forms.
Above, though image processing system 10 is illustrated as color M FP, it will be understood by a person skilled in the art that, can be used for various image processing systems such as monochrome printers according to fuser 31 of the present utility model.
Though embodiment of the present utility model is illustrated,, these embodiments only are for example of the present utility model is described, are not for limiting scope of the present utility model.For example, as long as need to detect the front end of paper or the position of rear end herein, paper detecting sensor can be arranged in the optional position of paper transportation path, and therefore device described herein and method can embody by multiple other modes.And in the scope that does not exceed the utility model aim, described device and method can be carried out some omissions certainly, be substituted or distortion.Claims and equivalency range thereof contain these modes or the distortion that falls into scope of the present utility model and aim.
