Description
Technical field
General plotting of the present invention relates to a kind of imaging device.More particularly, general plotting of the present invention relate to a kind of with toner image to the print media fixing device and the imaging device with this fixing device.
Background technology
Imaging device (for example, printer, duplicating machine, scanner, multi-purpose machine etc.) comprises and is used to make by well known to a person skilled in the art that transfer device is transferred to the fixing device of developer image (for example, the toner image) photographic fixing on the paper.
In order to satisfy recent needs, need the temperature of quick rising imprinting area, so that fixing device can reach fixing temperature as soon as possible to high speed imaging equipment.In addition, need thermal stability, thereby carry out the photographic fixing operation when keeping constant temperature, described constant temperature is not subjected to the influence of thermal perturbation (for example, being supplied to the change of type of the paper of imaging device).
Figure 1A to Fig. 1 C is the cut-open view of schematically illustrated traditional fixing device.Figure 1A illustrates roller fixing device, and Figure 1B illustrates the belt fixing device, and Fig. 1 C illustrates and comprises that embossed region forms the another kind of belt fixing device of member.
In Figure 1A, traditional roller fixing device comprises rotation and the closely backer roll 10 and the warm-up mill 20 of contact and be installed in thermal source 30 in the warm-up mill 20 each other.
Gou Zao traditional roller fixing device is when paper P passes owing to the embossed region N that the contact of the backer roll 10 of contact and the pressure between the warm-up mill 20 forms rotatably each other as mentioned above, heat and pressure are applied to by well known to a person skilled in the art that transfer device is transferred on the toner image of lip-deep not photographic fixing of paper P, then, toner image is fused on the paper P.The tradition roller fixing device helps flying print, and this is because when the paper of supplying with temperature reduction relatively after a little while.But, because warm-up mill 20 has bigger thermal capacity, so be difficult to raise fast temperature.Embossed region N utilizes a pair of roller 10 and 20 and form, thereby, produced restriction to how keeping stable embossed region width.
With reference to Figure 1B, another kind of conventional belt fixing device comprise a pair of backer roll 11 and 12 that forms embossed region N, photographic fixing band 22, flexibly support photographic fixing band 22 a side idler roller 40 and heat is applied to thermal source 31 on the photographic fixing band 22.
Gou Zao conventional belt fixing device utilizes thermal source 31 (for example, heating lamp) heat to be applied directly on the zone of photographic fixing band 22 of non-embossed region N as mentioned above, and therefore, photographic fixing band 22 can have little thermal capacity.Thereby the conventional belt fixing device helps making temperature to raise fast.But, the photographic fixing band 22 that applies tension force so that 22 rotations of photographic fixing band can be worn and torn.In addition, but the temperature fast rise of photographic fixing band 22 itself, but in fact since photographic fixing band 22 and described a pair of backer roll 11 with 22 and idler roller 40 contact rotatably and cause a large amount of thermal loss, so the temperature of embossed region N can be with low relatively speed rising.In addition, embossed region N utilizes described a pair of backer roll 11 and 12 to form, and therefore, has restriction to obtaining stable embossed region width.
With reference to Fig. 1 C, comprise photographic fixing band 22 that another traditional belt fixing device that embossed region forms member comprises backer roll 10, rotates by the revolving force that transmits from backer roll 10, be used for contact area between backer roll 10 and photographic fixing band 22 and form the embossed region formation member 50 of embossed region N, flexibly support the idler roller 41 of a side of photographic fixing band 22 and the thermal source 32 that is installed in idler roller 41.
As the conventional belt fixing device that comprises embossed region formation member of constructing among Fig. 1 C the width of embossed region N is increased, this is because embossed region N forms by embossed region formation member 50 is exerted pressure.But when the two ends that embossed region forms member 50 are compressed against when forming embossed region N on the backer roll 10, embossed region forms member 50 can be crooked, thereby be difficult to guarantee stable embossed region width on the Width of paper P.Correspondingly, the marginal portion of paper P contacts fully with backer roll 10, thereby can obtain enough embossed region width.But the deflection that forms member 50 owing to embossed region can not contact the center section of paper P fully with backer roll 10, thus be difficult to obtain enough embossed region width, thus make the photographic fixing effect relatively poor.

Embodiment
Now, will describe the exemplary embodiment of general plotting of the present invention in detail, its example shown in the accompanying drawings, wherein, identical label will be represented components identical all the time.Below, embodiment is described with reference to the accompanying drawings to explain general plotting of the present invention.
Fig. 2 be schematically illustrated according to the present invention the cut-open view of the fixing device of the exemplary embodiment of general plotting, Fig. 3 is the cut-open view of example that the structure of the fixing device shown in Fig. 2 is shown, wherein, this fixing device comprises heat transmission unit in the imprinting area of its embossed region formation member.
In Fig. 2 and Fig. 3, the fixing device of the exemplary embodiment of general plotting can comprise that backer roll 100, photographic fixing band 200, embossed region form member 310 and thermal source 400 according to the present invention.
For toner image is impressed into print media (for example, paper P) and with this toner image to this print media, backer roll 100 can receive driving force and thus the rotation.Backer roll 100 can be long and cylindrical shape.
Embossed region forms member 310 and can be installed in the photographic fixing band 200, thereby can form embossed region N on the contact area between backer roll 100 and the photographic fixing band 200.Embossed region forms member 310 can have the rotation of substantially cylindrical shape with guiding photographic fixing band 200, and can be fixed on the photographic fixing framework (not shown) of fixing device.Embossed region forms member 310 can be for having the metallic elastic body of predetermined elasticity, thereby scalable acts on the pressure on the backer roll 100.
The imprinting area 312 that embossed region forms member 310 can have different shape.For example, though do not illustrate among the figure, in the face of a side of the imprinting area 312 of backer roll 100 can have the curved surface that forms along the periphery of backer roll 100, with by increasing to adhering to of paper P improving photographic fixing efficient.Perhaps, the basal surface in imprinting area 312 can easily to supply with and to discharge paper P, prevent that paper P from stopping up towards backer roll 100 outstanding at least one projection.
