Fig. 7 illustrates the synoptic diagram of the section construction of imaging device in accordance with another embodiment of the present invention.As shown in Figure 7, lid 6 can comprise that leader 7 comes the operation of closing up of guide knobs 70.Leader 7 guide knobs 70 are rotated smoothly and are closed up, and close and cover 6.When lid 6 touched the front end of the knob 70 shown in Fig. 3 dotted portion, because the friction force between lid 6 and the knob 70, knob 70 perhaps can not rotate smoothly.When lid 6 when shutting, the leader 7 of present embodiment pushes away the fore-end of knob 70 on lightly, therefore guarantees to carry out smoothly the operation of closing up of knob 70.
Leader 7 can comprise from covering the guide hump 7a that 6 inside surface 6a stretches out.Guide hump 7a forms like this: when lid 6 was shut, knob 70 at first contacted with leader 7a before the inside surface 6a with lid 6 contacts.
Illustrated that in the present embodiment leader 7 has convex shape, yet leader 7 is not limited to convex shape.Leader 7 can have can be by assign to any other structure of closing up operation of guide knobs 70 of the leading section that upwards pushes away knob 70.
Fig. 8 is the synoptic diagram that illustrates according to the section construction of the imaging device of further embodiment of this invention.Do not indicate the framework of process cartridge unit among Fig. 8, and indicated knob 70a.
As shown in Figure 8, the knob 70a of process cartridge unit can be installed on the outside direction of main body 1 with being inclined upwardly.Knob 70a is inclined upwardly, and therefore when knob 70a contacts with lid 6, can close up more stably.
As shown in Figure 8,, cover 6 and close up knob 70a more reposefully, at knob 70a with cover between 6, from the rotation center (O of knob 70a in order to make when knob 70a and lid 6 when contacting
1) to the line (X) between the contact point (C) with from covering 6 rotation center (O
2) should be set at less than 90 degree to the angle (α) between the inside surface 6a of the lid 6 between the contact point (C).
In state as shown in Figure 8, be called θ about the angle of horizontal direction (H) as operculum 6
1, and line (X) is called θ about the angle of horizontal direction (H)
2, angle (α) is angle (θ so
1) and angle (θ
2) poor (that is α=θ,
1-θ
2).
(α) is more little for angle, and knob 70a can close up more more reposefully.Therefore, preferred angle (θ
1) be set to as far as possible little, perhaps angle (θ
2) be set to big as far as possible.Yet, in order to reduce angle (θ
1), knob 70a will stretch out longer in main body 1 outside direction.Therefore, be preferably on the structure angle (θ
2) be arranged to greatly as far as possible, rather than reduce angle (θ
1).
Angle (θ
2) increase and to mean that the acclivitous angle of knob 70a increases.But, if do not consider installation (or removing) angle of process cartridge unit, only adjust the setting angle of knob 70a arbitrarily, because big difference between installation (or removing) angle of the setting angle of knob 70a and process cartridge unit, cause the user can have any problem when holding knob 70a installation or removing process cartridge unit.
For example, install or remove if process cartridge unit is configured to along continuous straight runs, and knob 70a installs with bigger pitch angle with respect to horizontal direction, the user can not easily install or remove process cartridge unit so.In addition, because the user does not overlap with the direction of removing process cartridge unit (for example horizontal direction) substantially by the direction of holding knob 70a and putting on the power on the process cartridge unit, when the user wants process cartridge unit removed, will apply bigger power to process cartridge unit from imaging device.
In this, as shown in Figure 9, preferred process box 60a is installed on the main body 1 with predetermined angle of inclination, and knob 70a is arranged essentially parallel to the installation direction installation of process cartridge unit 60a.Line among Fig. 9 (P) is represented the installation direction of process cartridge unit 60a, is about to the direction that process cartridge unit 60a packs main body 1 into or removes from main body 1.Line among Fig. 9 (Q) is represented the installation direction of knob 70a.Knob 70a is inclined upwardly a bit from the installation direction of process cartridge unit 60a, with guarantee knob 70a to close up operation more steady.
Main body 1 can provide and be used for the installation of boot process housing unit 60a or the guide rail of removing 8.Guide rail 8 can be provided at respectively on 1 two inner surfaces of main body.The guide hump of reference numerals 67 expression process cartridge unit 60a, it guides by guide rail 8.Guide hump can be provided at respectively on the both sides of process cartridge unit 60a.
Equally, if guide rail 8 is provided on the main body 1, the installation of process cartridge unit 60a (or removing) direction is by the angle of inclination decision of guide rail 8 so.Therefore, the knob 70a of preferred process housing unit 60a is arranged essentially parallel to guide rail 8 installations.
More than describe as seen, the process cartridge unit of each side can make under the state of volume in being installed to imaging device of process cartridge unit and minimize according to the present invention, and this is that knob rotates and closes up because during the lid when shutting main body on, and during the lid on opening main body, the knob rotary expansion.Therefore, the size of imaging equipment body also can reduce.
In addition, because only by opening the operation of lid, the knob of process cartridge unit just is deployed into the outside of main body by opening, so the user can easily hold the knob of process cartridge unit.
Though carried out diagram and description as one exemplary embodiment of the present invention, but those skilled in the art person should be understood that, because technical development can be made multiple variation to the present invention, revise and carry out the replacement of equivalent element, and does not depart from the scope of the present invention.Adopt instruction of the present invention can make multiple modification, displacement, increase and part combination for specific situation, and do not leave scope of the present invention.For example, sheet feeding unit, paper feed unit and fixation unit shown in Figure 1 can be also as shown in Figure 1 the part of image-generating unit.Therefore, be intended to the present invention and be not limited to disclosed a plurality of one exemplary embodiment, but the present invention includes all embodiment within the scope that falls into claims.
