Below, with reference to accompanying drawing, the example of implementing optimal morphology of the present invention and comprising embodiment is described.In following comparative example, example and variation etc.,,, illustrate once with prosign that explanation is afterwards just omitted as far as possible about inscapes such as parts with same function and members with regard to attached as long as can differentiate.In order to make drawing and interest of clarity, even the inscape that should represent at drawing specify as there is no need in the drawings, then no longer be illustrated and suitably omit.
Fig. 1 represents to be suitable for one of image processing system of the present invention example.At first, illustrate that with reference to Fig. 1 the integral body of image processing system constitutes and action.
Image processing system shown in this figure is the image processing system structure that forms the tandem of coloured image.This image processing system has the 1st to the 4th cartridge processing 1Y, 1C, 1M, 1BK in image forming device body of being installed in 7 and the intermediate transfer belt 2 as the intermediate transfer body that disposes with these cartridge processing subtends.Intermediate transfer belt 2 is a kind of seamless belts, and volume hangs on a plurality of rollers 3,4,5 with driven roller and driven voller.Each cartridge processing 1Y to 1BK, have as drum type photoreceptor (hereinafter referred to as " photoconductor drum ") 6Y, 6C, 6M, 6BK as the mounting body, form toner images of different colors on each photoconductor drum respectively, each toner picture is transferred on the intermediate transfer belt in turn.
The formation of each cartridge processing 1Y to 1BK makes it can be along the length direction of the rotating shaft (not shown) of each photoconductor drum 6Y to 6BK, and with respect to image forming device body 7 loading and unloading freely, described length direction can roughly be regarded the switching direction of aftermentioned positioning unit as.
The formation of the 1st to the 4th cartridge processing 1 to 1BK, and will be formed at toner on each photoconductor drum 6Y to 6BK and look like to be transferred to formation on the intermediate transfer belt 2, its difference only is the color difference of each toner picture, and is identical in fact.Therefore, the formation of the 1st cartridge processing 1Y only is described typically and the toner on its photoconductor drum 6Y is looked like to be transferred to formation on the intermediate transfer belt 2 that other explanation is omitted.In addition, among each figure below Fig. 2, for same component part, the English words that only will represent color is paid and is remembered in cartridge processing, photoconductor drum and cartridge processing box body, in the hope of simple and clearization of drawing, omission is all given in the explanation of other component parts.
The 1st cartridge processing 1Y comprises: disposed charging device 11Y with charging roller 8Y etc. around photoconductor drum 6Y, have the display 9Y of developer roll 12Y etc. and had the cleaning device 10Y of cleaning doctor 13Y etc.Each machine box of these devices 11Y, 9Y, 10Y all is to be made of the cartridge processing box body 14Y as common unit box body.
Fig. 2 is the photoconductor drum 6Y of expression cartridge processing 1Y and the partial section that supports the mounting body holding components 15 of this photoconductor drum 6Y.In this figure, the diagram of other inscapes except that cartridge processing 1Y is omitted.Mounting body holding components 15 in this expression, also as shown in Figure 3, have as the supporting axis 16 of rotating shaft with by the bearing 17 that for example ball bearing constituted that is installed on this supporting axis 16 flange 18 of photoconductor drum 6Y by being fixed on its both ends, 19, fixedly be supported on the supporting axis 16.In addition, supporting axis 16 is by not shown bearing, and rotation is assembled on the cartridge processing 14Y freely.
Image forms and moves once beginning, and photoconductor drum 6Y just is driven in rotation along the clockwise direction among Fig. 1,2 rotation drivings in the direction of arrows of intermediate transfer belt.At this moment, surface and the rotation of the charging roller 8Y of charging device 11Y contact photoconductor drum 6Y.Be subjected to the effect of charging roller 8Y, photoconductor drum 6Y is charged with decided polarity.On the photoconductor drum 6Y after the charging, the modulated laser L irradiation through penetrating from the exposure device shown in Figure 1 20 with the not one of cartridge processing 1Y forms electrostatic latent image on photoconductor drum 6Y.
The developer roll 12Y of display 9Y is driven in rotation along the counter clockwise direction among Fig. 1.Upload at this developer roll 12Y and to be equipped with that dry type is existing to be transferred as agent, this existing dividing a word with a hyphen at the end of a line because of electrostatic interaction as the Yellow toner in the agent is attached on the electrostatic latent image that is formed on the photoconductor drum 6Y, but this electrostatic latent image as the Yellow toner picture by videoization.In addition, disposed clamping intermediate transfer belt 2, with the primary transfer roller 21Y of cartridge processing 1Y subtend as the primary transfer means because the effect of this primary transfer roller 21Y, and make the toner that is formed on the photoconductor drum 6Y look like to be transferred on the intermediate transfer belt 2.Attached to the transfer printing remaining toner on the photoconductor drum 6Y of toner after as transfer printing, the cleaning doctor by cleaning device 10Y strikes off from photoconductor drum 6Y surface.
Same fully with foregoing, on each photoconductor drum 6C, 6M of as shown in Figure 1 the 2nd to the 4th cartridge processing 1C, 1M, 1BK, 6BK, form cyan toner picture, magenta toner picture and black toner picture respectively, these toner pictures are overlapping in turn, be transferred to transfer printing has on the intermediate transfer belt 2 of Yellow toner picture.
On the other hand, as shown in Figure 1, the bottom in image forming device body 7 has disposed the paper feeding cassette of taking in as the transfer paper P of one of sheet-shaped recording medium example 22, and the transfer paper P of upper sends towards the direction of arrow B by the rotation of paper feed roller 23.The transfer paper P that is sent supply to intermediate transfer belt 2 and and the secondary transfer roller 24 as the secondary transfer printing means of its subtend configuration between, at this moment by the effect of secondary transfer roller 24, the toner on the intermediate transfer belt 2 looks like to be transferred on the transfer paper P.Transfer printing has the recording medium of toner picture further to be transported to the top, by fixation unit 25.At this moment, by the effect of heat and pressure, the toner picture on the recording medium is by photographic fixing.By the recording medium of fixation unit 25, be discharged in the top row's paper portion 26 that is positioned at image forming device body 7.Attached to the transfer printing remaining toner on the intermediate transfer belt 2 of toner after, remove by the cleaning unit 27 of intermediate transfer belt 2 usefulness as transfer printing again.
Secondly, illustrate that location when cartridge processing 1Y to 1BK is installed in image forming device body 7 constitutes and moves.As described later, example of the present invention is the improvement of being done to location structure (to call " comparative example " in the following text) shown in Figure 7 at Fig. 2, now is described in detail with regard to its details.
Symbol F among Fig. 2, presentation video forms the front side of device, and symbol R presentation video forms the inboard of device, i.e. rear side.Cartridge processing 1C, 1M, the 1BK of cartridge processing 1Y and other, as described later, along fore-and-aft direction, in other words, i.e. the length direction of supporting axis 16, image forming device body 7 loading and unloading are installed in this image forming device body 7 freely relatively.Composing images forms the framework 33 of device 7, has the front side board 28 that is configured in its front side and the base plate 30 (Fig. 3) of back side panel 29 as shown in Figure 3, that be configured in its rear side and fixed side 28,29 usefulness.
Be formed at the opening 31 on the front side board 28 of image forming device body 7 one sides, shown in Fig. 2 and Fig. 4 etc.,,, covered usually by the positioning unit 65 that is used to load and unload the location, can open and close freely with each cartridge processing 1Y to 1BK by each mounting body holding components 15.Positioning unit 65 shown in Fig. 2 and Fig. 4 to 7, mainly is made of single location holding member 32 and pushing means described later.Described location holding member 32 is provided with two faces 45,46 as maintaining part, and it is formed on the mounting hole 37, and when with respect to opening 31 closures of front side board 28 time, each mounting body holding components 15 is kept by the mounting hole 37 of described opening.Described pushing means pushing is maintained at each the mounting body holding components 15 on the face 45,46, positions.
Around framework 33 and location holding member 32, be provided with outer cover plate and by the front shroud of its support (all not shown).
As shown in Figures 2 and 3, location holding member 32 is by a double spread latch 34, can be by direction shown in arrow C, the D, in deciding angular range rotationally, can swing, open and close pivotally connected freely on front side board 28, occupy make-position as shown in Figure 2 usually.When location holding member 32 occupies make-position, when the pilot hole 35a that forms on the holding member 32 of location is embedded on the register pin 36a that is convexly equipped with on the front side board 28, other pilot holes 35b in location holding member 32 formation, be embedded in the register pin 36b that is convexly equipped with on front side board 28, location holding member 32 is located with respect to the framework 33 of image forming device body.The position of location holding member 32 of this moment, be with respect to framework 33 location fixed installation site.Therefore, location holding member 32 is with respect to the framework 33 of image forming device body 7, be positioned on the fixed installation site, be mounted to switching freely.
As shown in Figure 3, on the holding member 32 of location, form mounting hole corresponding to each mounting body holding components 15.Holding member 32 is in as shown in Figure 2 make-position when the location, promptly fixed installation site the time, in its each mounting hole 37, embed, maintain the front part of each mounting body holding components 15, be each bearing 17 in this example.As described later, the front part of each mounting body holding components 15 is located with respect to location holding member 32.Like this, on the holding member 32 of location, be installed under the state of installation site, form the mounting hole 37 that embeds, keeps each mounting body holding components 15 at this location holding member 32.
On the other hand, as shown in Figure 2, the inboard end at the supporting axis 16 of the photoconductor drum 6Y that supports cartridge processing 1Y is fixed with mounting body gear 38.On back side panel 29 rotation supporting freely can with the axle 40 of the cup-shaped gear 39 of mounting body gear 38 loading and unloading, under the state of this figure, mounting body gear 38 is limited on the cup-shaped gear 39.In view of the above, the end of supporting axis 16 inboards is for back side panel 29, is positioned at the length direction of supporting axis 16.Front and inboard at cartridge processing 14Y convex with the pin that not shown non-return is used, and these pins are embedded in the hole (not shown) that is formed on location holding member 32 and the back side panel 29, take this, and can stop cartridge processing 1Y around supporting axis 16 rotations.
The end of each supporting axis 16 inboard of other cartridge processings 1C, 1M, 1BK, also same fully with above-mentioned content, be positioned on the back side panel 29, and its each supporting axis 16 and photoconductor drum 6C, 61M, 6BK and above-mentioned content fully similarly are driven in rotation.
Under the state that stops motor work, when opening not shown Qianmen, make location holding member 32 turn to as shown in Figure 3 open position, then opening 31 is open.Under this state, as cartridge processing 1Y being pulled to the preceding extreme direction shown in the arrow E, then cartridge processing 1Y is drawn out to preceding extreme direction under the guiding of the guide rail that constitutes not shown loading and unloading means.Otherwise if each cartridge processing 1Y is pushed away toward the inboard direction shown in the arrow G, then this cartridge processing 1Y will be pressed into inboard direction under the guiding of above-mentioned guide rail.Secondly as shown in Figure 2, mounting body gear 38 is limited to umbrella gear 39, and the inboard end of supporting axis 16 is located with respect to framework 33,, location holding member 32 is swung to as shown in Figure 2 make-position, makes it with respect to front side board 28 location.Under this state, as described later, the front part of supporting axis 16 can be located framework 33.Then, by the above-mentioned Qianmen of closure, can begin image and form action. Other cartridge processing 1Y, 1M, 1BK are also same fully, can be for image forming device body 7 loading and unloading.
Secondly, just the front of each mounting body holding components 15 is partly done an explanation for the concrete formation that the framework 33 of image forming device body 7 positions.
As previously mentioned, Fig. 4 is that expression is pressed into the image forming device body inboard with each cartridge processing 1Y to 1BK, make location holding member 32 turn to make-position, with the pilot hole 35a that is formed on the holding member 32 of location, 35b is fitted to register pin 36a, the 36b that is convexly set on the front side board 28, with location holding member 32 be positioned the outside drawing during fixed installation site, the view that this figure system is looked from Fig. 2 arrow IV direction.From this figure and Fig. 2 and Fig. 6 as can be known, on the holding member 32 of location, disposed slide unit 41.
On slide unit 41, be formed with the very long slotted hole of a plurality of horizontal directions.In each slotted hole 42, can be slidably inserted into band stepped screw 43 relatively, this respectively is with stepped screw 43 to be screwed onto on the holding member 32 of location.Take this, slide unit 41 can be supported between as shown in Figure 4 the 1st position and the 2nd position as shown in Figure 5 on the holding member 32 of location with moving horizontally.
If make location holding member 32 swing to as shown in Figure 4 make-position from open position shown in Figure 3, then each bearing 17 is embedded in each mounting hole 37 that is formed on the holding member 32 of location.At this moment, as understanding from Fig. 4, the size of each mounting hole 37 is set the cross-sectional area greater than each supporting axis 16 and chimeric each bearing 17 on it for, and each bearing 17 is embedded in each mounting hole 37 with big play.Thus, can like a cork each bearing 17 be embedded in each mounting hole 37.As shown in Figure 4, in each mounting hole 37, be provided with, and another flexure plane 47 vertical guide 45 and surface level 46 state that roughly is orthogonal mutually as the vertical guide 45 that keeps bearing 17 maintaining parts and two faces of surface level 46.
On the other hand, as Fig. 2, Fig. 4, Fig. 5 and shown in Figure 6, set up each push part 44 respectively corresponding to each bearing 17.Also as shown in Figure 7, each push part 44 has the wedge-shaped part 53 that front end forms the tapered wedge shape.In addition, on each push part 44, form the slotted hole 48 that approximate horizontal is extended, in each slotted hole 48, respectively can be chimeric relatively slidably by the brake block of forming by the band stepped screw that is bolted in slide unit 41 49.Take this, each push part 44 can with respect to slide unit 41 with fixed stroke move in the horizontal direction.
In addition, the downside of the flange portion on slide unit 41 tops has the effect of the guide surface 50 that guides this push part 44 when each push part 44 moves in the horizontal direction.Like this, on slide unit 41, form the guide surface 50 that each push part is used.
As shown in Figure 4, be convexly set on each bayonet lock 51 on each push part 44 and the slide unit 41, card ends each end of the extension spring 52 that the means of energizing use respectively.Take this, each push part 44 is given right-hand potential energy in Fig. 4.But when slide unit 41 occupied as shown in Figure 4 the 1st position, each brake block 49 of a side end 61 butts of above-mentioned each slotted hole 48 made each push part 44 stop at as shown in Figure 4 position.At this moment, each push part 44 does not contact each bearing 17 of each mounting body holding components 15.
Like this, each push part 44 under the state of being composed with potential energy by spring 52, is propped up movably and is held in slide unit 41.When slide unit 41 is in the 1st position, compose the restriction that is subjected to being located at the brake block 49 on the slide unit 41 with the push part 44 of potential energy by spring, being under an embargo contacts with mounting body holding components 15.Therefore, when operator's manual operation, when location holding member 32 was swung to as shown in Figure 4 make-position from as shown in Figure 2 open position, each bearing 17 can not disturb each push part 44, and embeds in each mounting hole 37.
Secondly, if the operator incites somebody to action slide unit 41 as shown in Figure 4, it is right-hand by manual operation it to be slided into, when occupying the 2nd position as shown in Figure 5, then the wedge-shaped part 53 of each push part 44 is pressed between each bearing 17 of guide surface 50 and each mounting body holding components 15, each bearing 17 is pressed against on two faces 45,46 of each mounting hole 37.Below further describe the effect of this moment.
If slide unit 41 is begun to move to the 2nd position as shown in Figure 5 from as shown in Figure 4 the 1st position, then compose with potential energy by each spring 52, and, by each push part 44 of each brake block 49 restrictions with slide unit 41, beginning right-hand mobile in Fig. 4.Then, if slide unit 41 arrive between the 1st positions and the 2nd position during fixed position, the wedge-shaped part of being composed with each push part 44 of potential energy by each spring 52 53 just is pressed between each bearing 17 of guide surface 50 and each mounting body holding components 15, is crimped on the outer peripheral face of each bearing 17 and stops.In view of the above, each push part 44 presses against each bearing 17 on two faces 45,46 of each mounting hole 37 forcefully.
Each push part 44 stops (motion) afterwards, if resist potential energy (spring) power of each spring 52, slide unit 41 is moved towards the 2nd position, each brake block 49 is left in each end 61 that then is formed at the slotted hole 48 on each push part 44, the restriction cancellation from each brake block 49 that each push part 44 is suffered.
As mentioned above, the pushing force that forms by the wedge-shaped part of composing by each spring 52 with each push part 44 of potential energy 53, each bearing 17 is crimped on two faces 45,46 of each mounting hole 37, therefore, each mounting body holding components 15 and be the front part of its each photoconductor drum 6Y to 6BK that supports can be made correct positioning with respect to location holding member 32.At this moment, because this location holding member 32 is done correct location with respect to framework 33, therefore, finally each photoconductor drum 6Y to 6BK can do correct location with respect to the framework 33 of image forming device body 7.The operator will locate holding member 32 and be installed on institute's allocation with respect to framework 33, if mobile slide unit 41, just can be with each photoconductor drum 6Y to 6BK with respect to image forming device body 7 location.And, because setting is formed at the cross-sectional area of the size of the mounting hole 37 on the holding member 32 of location much larger than the front end of mounting body holding components 15, so each mounting body holding components 15 can be embedded in each mounting hole 37 like a cork.
Certainly, the location holding member 32 with respect to framework 33 dimensional accuracy, and the spacing of two faces 45,46 of each mounting hole 37 of location holding member 32 and the dimensional accuracy of each one, much less, all be set in can make each photoconductor drum 6Y to 6BK with respect to image forming device body 7 do the location within the fixed accuracy rating (tolerance).
As mentioned above, pushing means are mainly by being constituted with lower member: corresponding to each mounting body holding components 15 be provided with, and each maintaining part on each mounting body holding components 15 for non-contacting non-pushing position and pushing, locate between the pushing position of each the mounting body holding components 15 on each maintaining part (two faces 45,46), a plurality of push part 44 movably; As the means of energizing, compose extension spring 52 with the potential energy of shifting to the pushing locality for each push part 44; When supporting each push part 44 movably, propping up the single slide unit 41 that is held in location holding member 32 movably corresponding to the 1st position of non-pushing position with between corresponding to the 2nd position that pushes the position; At the mobile means (not shown) that slide unit 41 is moved between the 1st position and the 2nd position.
At this, with for example be recorded in the form that the spy opens the locator meams contrast of the picture mounting body unit on the 2001-222207 communique (patent documentation 6), put the problem of its existence in order.[0067] section of above-mentioned communique, putting down in writing following technology item: " ... (part omitted); the axle 12a of the photoconductor drum 12 of cartridge processing 10;, correctly locate, remain in coloured image and form in the device by the bearing portion 201 of the CRG bearing 200 of the unitor 95 of driver element 90, open-close lid unit 500, hole 111 and each accessory 115,116 location of action plate 110.…”。Therefore, technology by the record of above-mentioned communique exists following problem: guaranteed as long as carry out the dimensional accuracy of localization part of bearing portion 201 of the CRG bearing 200 of transverse direction location, can become big with the frictional resistance of axle 120a when chimeric of each photoconductor drum 12, even little by little stagger the opportunity of the axle 120a of each accessory 115,116 each photoconductor drum 12 of butt, locate the easy manipulation that to look to reaching as routine in the past in above-mentioned the present patent application longitudinally.In addition, the problems such as wearing and tearing that also also have the sliding friction because of location, auxiliary section to bring.
As mentioned above, as Fig. 1 to image processing system shown in Figure 7, the push part 44 that the mounting body holding components 15 that having can be with loose fit, promptly be embedded in each mounting hole 37 pushes for two faces 45,46 of each mounting hole 37, this push part 44 has the wedge-shaped part 53 that is pressed between guide surface 50 and the mounting body holding components 15, is used to push mounting body holding components 15.And when slide unit 41 was positioned at the 1st position, the push part 44 by spring 52 is composed with potential energy was subjected to being located at the restriction of the brake block 49 on the slide unit 41, and it is under an embargo with contacting of mounting body holding components 15.When slide unit from the 1st position when move the 2nd position, spring is composed with potential energy, and moved with slide unit 41 by the push part 44 of brake block 49 restriction.When this slide unit 41 arrived position between the 1st positions and the 2nd position, by the push part 44 of spring 52 taxes with potential energy, its wedge-shaped part 53 was pressed between guide surface 50 and the mounting body holding components 15 and stops.Because further to the moving of the 2nd position, the position of slide unit 41, push part 44, spring 52 and brake block 49 is set slide unit, makes push part 44 remove the restriction that is limited by brake block 49.
When allowing slide unit 41 occupy as shown in Figure 5 the 2nd position, because the wedge-shaped part 53 of each push part 44 is pressed between the outer peripheral face of guide surface 50 and each bearing 17, the effect that is subjected to its friction force and spring 52 to compose potential energy power, each mounting body holding components 15 is maintained on the regular position, can continue correctly to locate each photoconductor drum 6Y to 6BK.In addition,, return the 1st position as shown in Figure 4 once more, then because each push part 44 is left the outer peripheral face of each bearing 17, so can make location holding member 32 be rocked to as shown in Figure 3 open position without barrier if by manual operation slide unit 41.
In addition, because the faces that roughly are orthogonal mutually by two faces 45,46 of each mounting hole 37 of each mounting body holding components 15 pushings so can stable status keep each mounting body holding components 15, carry out correct positioning to it.
In addition, as shown in Figure 7, as wedge-shaped part 53 angulations of establishing each push part 44 are θ, and then if this angle θ is excessive, its wedge-shaped part 53 is pressed between guide surface 50 and the bearing 17 needs very big power, and operating performance is low.Otherwise if this angle θ is too little, then the actuating length of push part 44 increases in rain, and operating performance is still low.Based on this viewpoint, this angle θ preferably sets between 5 ° to 45 °, preferably between 15 ° to 20 °.
Again, as Fig. 2 and shown in Figure 7, if be formed at two faces 45,46 of the mounting hole 37 on the holding member 32 of location, be to take to cut the words that the tongue piece 55,56 that shapes makes during by pressure forming, then because the base portion of this tongue piece 55,56 does circular 57, when will locating holding member 32 when turning to as shown in Figure 2 make-position, circular 57 part becomes with bearing 17 and is slidingly connected, so can prevent unfavorable conditions such as this bearing 17 is scratched.
Equally, the face of the push part 44 that contacts with mounting body holding components 15, if taking to cut the tongue piece 58 that shapes during with pressure forming makes, then as shown in Figure 2, because the base portion at its tongue piece 58 forms circular 60, so when working as bearing 17 butts of push part 44 and mounting body holding components 15, can prevent to injure the unfavorable condition of this bearing.
More than Shuo Ming image processing system has a plurality of photoconductor drum 6Y to 6BK, is used to push a plurality of push part 44 of the mounting body holding components 15 of supporting this each photoconductor drum, props up movably respectively and is held in common slide unit 41.Therefore, only move single slide unit 41, just can make 44 actions of all push part, each mounting body holding components 15 is pressed on two faces 45,46 of a mounting hole 37 by each push part 44.
In addition, in image processing system as shown in the figure, it constitutes; Fixedly supporting photoconductor drum 6Y to 6BK on the supporting axis 16 of each mounting body holding components 15, rotation drives the supporting axis 16 of each mounting body holding components 15, and photoconductor drum 6Y to 6BK is rotated.Thus, the front part that is formed in the supporting axis 16 of each mounting body holding components 15 is installed bearing, makes each bearing 17 loose fit in each mounting hole 37.In contrast, correctly constitute when the rotation of each photoconductor drum is supported in each supporting axis freely, do not rotate this supporting axis, and only rotation drives under the situation of photoconductor drum, supporting axis directly can be entrenched in the mounting hole.For this reason, mounting body holding components in the case also can not be provided with pine and be embedded in bearing 17 in the mounting hole 37.
In this routine image processing system, supporting axis 16 is that one is assembled on the photoconductor drum 6Y to 6BK, but also can make each supporting axis with rotation freely, the mode that maybe can not rotate is assembled in the frame side of image forming device body, and photoconductor drum can releasably be assembled at its axis direction with respect to supporting axis.This image processing system can not have the ground of obstruction yet and adopts above-mentioned each structure.In addition, in the case, when the supporting axis rotation is supported on the framework freely, constitute mounting body holding components by its supporting axis and the bearing that is installed on its front part, supporting axis can not rotate be assembled on the framework time, its supporting axis also can directly be entrenched in the location holding member mounting hole in.
, also can be applicable to without barrier in the image processing system that a photoconductor drum only is set to each formation shown in Figure 7 as Fig. 1.
Though illustrate successively, but because location holding member 32, slide unit 41 and each push part 44 etc. all are the sheet metals that is used as sheet material, make above-mentioned each one integrally formed, so it is very cheap, and can guarantee to obtain on fixed intensity and wearing quality, this advantage of permanance, also prove effective very much.
The 1st example
Fig. 8 to Figure 16 represents the 1st example.The 1st example is compared to the image processing system of comparative example shown in Figure 7 as Fig. 1 with conduct, and the main difference point is, uses the positioning unit 70 shown in Fig. 8 etc. to substitute positioning units 65.
Positioning unit 70 is compared with positioning unit 65, and its main difference point is: use the location holding member 32A as holding member shown in Fig. 8 etc. to substitute location holding member 32; Use the slide unit 41A of formation pushing means as shown in figure 15 to substitute slide unit 41; Use the alternative push part 44 of push part 44A to formation pushing means shown in Figure 11 as Fig. 9; Remove the brake block of forming by the band stepped screw 49; Use the spring 71 alternative extension springs 52 to formation pushing means shown in Figure 13 as Figure 10; Clamping slide unit 41A, with the outside of the subtend of location holding member 32A, newly establish cover plate part 90; And has a mobile means as shown in figure 14 92 that slide unit 41A is moved between the 1st position and the 2nd position.Except above-mentioned difference, all the other are identical with positioning unit 65.
As Fig. 8 and shown in Figure 14, the main of positioning unit 70 is made of single location holding member 32A and pushing means described later.Described location holding member 32A is provided with two faces 78,79 as maintaining part, and it is formed on the mounting hole 77, and when with respect to opening 31 closures of front side board 28 time, each mounting body holding components 15 is kept by the mounting hole 37 of described opening.Described pushing means pushing is maintained at each the mounting body holding components 15 on the face 78,79, positions.
As shown in Figure 8, integrally formed tongue piece 80,81 on opening mounting hole 77, described tongue piece 80,81 is respectively equipped with two faces 78,79, as maintaining part, by the deadweight maintenance mounting body holding components 15 of each cartridge processing 1Y to 1BK.Have 78,79 tongue piece 80,81 of two faces, showing perpendicular line greatly is the center, and its both sides are with about equally angle (45 °), and roughly being orthogonal mutually forms.It plays two functions that face is same of V piece used when being used for pole shape axle and centering.
On the other hand, keeping, when locating, such situation arranged with 37 pairs of mounting bodies of the mounting hole holding components 15 that has two vertical guides 45 and surface level 46 shown in Fig. 6 and 7: a kind of is uncertain toward mounting, hold mode on two faces 45,46 of mounting body holding components 15 by the deadweight of each cartridge processing 1Y to 1BK; Another kind is that even lean on the pushing effect of push part 44, mounting body holding components 15 does not contact vertical guide 45 especially yet, and is affiliated on surface level 46, can't remain on the regular position.In this example, this point is also improved.
Same with comparative example as shown in Figure 7, two faces 78,79 are if the words that the tongue piece 80,81 that having cut during by pressure forming shapes forms, then form circle because of base portion at this tongue piece 80,81, so will locate holding member 32A when rotating to as shown in Figure 2 make-position, circular portion and bearing 17 sliding contacts can prevent to injure the unfavorable condition of bearing 17.
In addition, if do not expect this advantage especially, also can not form tongue piece 80,81, and keep at the section of the mounting hole 77 that is equivalent to thickness of slab.The diagram of tongue piece 80,81 just to making drawing succinct bright and show, is then omitted in other figure.In addition, the shape of mounting hole 77 only correctly is illustrated among Fig. 8, then simply is expressed as roughly fan-shaped among other figure.
Certainly, with respect to the spacing of two faces 78,79 of each mounting hole 77 of the dimensional accuracy of the location holding member 32A of framework 33 and location holding member 32A and the dimensional accuracy of each one, much less all be set in to making each photoconductor drum 6Y to 6BK within the fixed accuracy rating (tolerance) in image forming device body location.
As shown in figure 14, cover plate part 90 forms by for example resin is integrated, protrudes at its both ends, left and right sides to form lug boss (boss) 90a that attachment screw is used.On the other hand, at the both ends of location holding member 32A, form the jack of screw 91, cover plate part 90 and location holding member 32A are spirally connected fixing with screw 91.Cover plate part 90 and location holding member 32A are located at the outside of 4 mounting holes 77 with maintaining part by the fixed position that screw 91 is spirally connected.Take this, can guarantee to locate the intensity of holding member 32A, especially very effective to the raising of the transverse strength of screw.
In addition, will form with integrative-structure to the chimeric shape 32c of swing fulcrum (with reference to folding latch shown in Figure 8) from the mounting body holding components retaining part 32b of location holding member 32A toward location holding member 32A.Then, with above-mentioned shape 32c part and mounting body holding components retaining part 32b, connect with the recessed flange that is shaped towards shape 32d.Take this, to mounting body holding components retaining part 32b, can guarantee bigger intensity from the swing fulcrum of location holding member 32A.
As shown in figure 15, in the holding member 32A of location because also form at the long side direction of mounting body holding components retaining part 32b recessed towards shape 32e, so can guarantee to locate the intensity of holding member 32A more.
And, because of recessed towards shape 32e be formed near be positioned at carrier support holding member 32b left and right sides mounting hole 77 about the more lateral of the maintaining part of two ends, so can guarantee to locate the intensity of holding member 32A more.
Shown in Figure 17 A, B, location holding member 32A's is recessed towards shape 32e part, is provided with the part that is slidingly fastened with slide unit 41A.In view of the above, the head end of band stepped screw 43 or the tail end of screw can not protrude the surface of location holding member 32A, are hung wound so can prevent the user by the tail end of screw 43 head ends or screw.
In addition, in example as shown in figure 15,, adopted the engaging of multiple spot compared with the engaging at both ends because the part that is slidingly fastened of location holding member 32A and slide unit 41A is located at both ends and the central portion of slide unit 41A, so, can guarantee to locate the intensity of holding member 32A more fully.
As mentioned above, compare with the slide unit 41 shown in Fig. 6 etc., the main difference of slide unit 41A has been to plug and has constituted the pin 93 of mobile means 92, and in example as shown in figure 15, has set up the part that is slidingly fastened of slip usefulness at central portion.
The pushing means of this example, extremely shown in Figure 13 as Fig. 8, mainly contain with the lower part and constitute: corresponding to each mounting body holding components 15 be provided with, each mounting body holding components 15 on each two face 78,79 is non-contacting non-pushing position, and pushing, locatees movably a plurality of push part 44A between the pushing position of each the mounting body holding components 15 on each two face 78,79; As composing with each push part 44A with spring 71 to the one-tenth U word shape of the means of energizing of the mobile potential energy of the direction of pushing position; When supporting each push part 44A movably, propping up the single slide unit 41A that is held in location holding member 32A movably corresponding to the 1st position of non-pushing position with between corresponding to the 2nd position that pushes the position.
Each push part 44A has between each the mounting body holding components 15 that is pressed on guide surface 50 and each two face 78,79, be used to push the wedge-shaped part 53 of each mounting body holding components 15.Only as shown in figure 13, same with the push part 44 of conduct comparative example as shown in Figure 7, the surface of contact of the push part 44A that contacts with the bearing 17 of mounting body holding components 15, if the tongue piece 58 that cutting during with press molding shapes is made, then because of forming circle at this tongue piece base portion, in the time of bearing 17 butts of push part 44A and mounting body holding components 15, can prevent that the injured unfavorable condition of bearing from taking place.
In Fig. 9, Figure 10, Figure 13 etc., fan-shaped and even circle that the web inner face of slide unit 41A is represented with double dot dash line have been to make drawing succinct, with the bearing 17 at imaginary existence projective representation's mounting hole 77 and mounting body holding components 15.
Has push part 44A with the wedge-shaped part 53 of the same cone shape of above-mentioned comparative example, be formed with: in the non-pushing position of conduct with the corresponding position of lancing shape 41a of slide unit 41A, and form in the moving range of pushing between the position mobile use slotted hole 44b and with the lancing shape 44a of lancing shape 41a subtend, opposite formation with its direction.And slide unit 41A and push part 44A are chimeric shown in Fig. 9 arrow H.Above-mentioned slide unit 41A and push part 44A, as shown in figure 10, set for separately lancing shape 41a relative with 44a to.
Lancing shape 41a and 44a mutually between, mounting the U font be the means of energizing be again the both ends 71a and the 71b of the spring 71 of elastomeric element, be subjected to the effect of the elastic force of this spring 71, push part 44A and slide unit 41A keep relative to, between push part 44A and slide unit 41A, be applied with tension force (tension).
The lancing shape 41a of slide unit 41A, end the angle of bend θ 2 of angle as being used to the card that card ends spring 71 usefulness, as shown in figure 11, set for more than the 45 with respect to the all-moving surface that slips of slide unit 41A.Angle of bend θ 2 as below 45 °, then the hook shape 71b of spring 71 is sandwiched between the lancing shape 41a and push part 44A of slide unit 41A easily, makes the action variation of push part 44A, so undesirable.
With reference to Figure 12, the details of spring 71 is described.Spring 71 is the shapes that roughly become the U font, its two ends be provided with can with each the lancing shape 41a of slide unit 41A and push part 44A and the curved shape 71a and the 71b of 44a hook.
Width between the U word portion open side two ends of spring 71, i.e. curved shape 71a, the width W 1 between the curved interior of 71b is less than the breadth extreme W2 of U word portion.Certainly, for ease of colluding extension, above-mentioned curved shape is made hook-shaped.Set W1＜W2, the tension force of nationality spring 71 can make spring 71 unlikely mobile to top shown in the arrow of Figure 13 thus.
In this example example, because use 4 springs,, much less be mode to avoid resonating etc. so consider loading that their add up to and the relation between the operating physical force, the loading of setting spring 71 and spring constant.
According to this example, by between the lancing shape 44a of the lancing shape 41a of slide unit 41A and push part 44A, mount the both ends 71a that roughly becomes U font spring 71,71b, can make push part 44A keep relative with slide unit 41A to, can remove the brake block 49 of the band stepped screw of conduct comparative example as shown in Figure 7.In addition, by adopting, can also further reduce cost such as the more cheap spring 71 of the extension spring 52 of comparative example shown in Figure 7.
According to this example, if angle of bend θ 2 is set in more than 45 °, the hook shape 71b of spring 71 is unlikely to be sandwiched between the lancing shape 41a and push part 44a of slide unit 41A, and the action of push part 44A can be carried out smoothly.
In addition, according to this example, if the width W 1 of the U word portion open side curved interior of spring 71 is made breadth extreme W2 less than U word portion, and (W1＜W2) then because of the effect of the tension force of spring 71, can make that spring 71 is unlikely to be moved to the top shown in Figure 13 arrow.
As Figure 14 and shown in Figure 16, mobile means 92 is to play the means that make slide unit 41A locomotive function between the 1st position and the 2nd position.It is by constituting with the lower part: as can decided direction promptly the arrow K direction among two figure do oscillating traverse motion, be arranged on the control lever 94 of the functional unit on the cover plate part 90; Control lever 94 works are transformed into the moving movement of slide unit 41A, promptly are transformed into the straight-line to-and-fro movement shift means of approximate horizontal in the oscillating traverse motion of arrow K direction.
This to-and-fro movement shift means mainly is made of following components: be plugged in the pin 93 on the slide unit 41A; Insert logical slotted hole 90b with the supply and marketing 93 that cover plate part 90 roughly becomes horizontal direction to form; Insert and to lead to formed hole 90c on cover plate part 90, the control lever base end part 94a that is connected and fixed with screw 95; The guide groove 94b that the base portion of the control lever 94 that embeds at pin 93 forms.
By guiding, restriction, pin 93 is moved along guide groove 94b, simultaneously, making pin 9 is the center with the screw 95 of control lever base end part 94a, general horizontal direction in slotted hole 90b moves, and the oscillating traverse motion along arrow K direction that control lever 94 is done is transformed into the approximate horizontal rectilinear motion of slide unit 41A.
With reference to Figure 18 to Figure 22 in detail, the mechanism of the bearing accuracy of the positioning unit 70 that improves image forming device body one side is described in detail.In this example, be to improve with regard to register pin 36a, the 36b of comparative example shown in Figure 3 and the chimeric locator meams of pilot hole 35a, 35b to form.
As shown in figure 18, on the holding member 32A of location, be provided with the slide unit 41A that slides in horizontal (general horizontal direction) represented with thick arrow, on this slide unit 41A, be formed with the hole 72 that connects circular hole and long hole shape.In addition, on the holding member 32A of location, be formed with when slide unit 41A occupies the 1st position, corresponding to the hole 73 of the circular hole position in hole 72.
As shown in figure 19, in body one side of image processing system, on the position corresponding, locating shaft 74 is set with above-mentioned each hole 72,73.By making location holding member 32A in image forming device body side oscillation and switching, locating shaft 74 enters in hole 73 and the hole 72.This moment, slide unit 41A occupied the 1st position.
By making slide unit 41A along the horizontal slip of representing with thick arrow, move to the 2nd position, locating shaft 74 and hole 73,72 are chimeric, and location holding member 32A is fixed on the image forming device body side.Take this, location holding member 32A can be fixed on the image forming device body side.
By form the chamfer shape 74a on inclined-plane (circular conical surface) as shown in figure 19 at the front end of locating shaft 74, locating shaft 74 can be easy to enter in each hole 73,72 of location holding member 32A and slide unit 41A.
In addition, shown in the sectional view of Figure 20, by front part at the venturi portion of locating shaft 74, in other words, by in the part of locating shaft 74 with the hole 72 chimeric sides of slide unit 41A, form chamfer shape 74b, can make slide unit 41A make sliding gomphosis easily.
Figure 21 shows the more level and smooth formation of action that makes slide unit 41A.Around the long hole shape portion in the hole 72 of slide unit 41A, form deep-draw shape 75 as protuberance.Its section is shown in Figure 22.By this, the action of slide unit 41A can further become level and smooth.
Figure 23 represents to locate the position relation between holding member 32A and the image forming device body side.Location holding member 32A, the folding latch 34 that can be used as the swing fulcrum is center swing and switching.This fulcrum is arranged on be connected with locating shaft 74 position of more lateral simultaneously of location holding member 32A.That is to say, can understand that in Figure 23, N more is in the outside than M.Take this, can prevent to locate the front that holding member 32A swings to left side among the figure.
As shown in figure 24, on slide unit 41A,, be formed with the consistent convex form 82 of height that contacts with the web inner face of location holding member 32A in locating shaft locating shaft direction nearby.Take this, move to as slide unit 41A under the situation of the 2nd position, can eliminate loosening rocking of being caused by locating shaft 74 directions.
That is, axial loosening the getting final product in this location as long as near the fitting portion of locating shaft 74, can not take place in the shape of location holding member 32A and slide unit 41A.
Secondly, the example of the operation sense that raising slide unit 41A move operation is followed is described.As shown in figure 25, on the holding member 32A of location, be provided with elastomeric element 84, on slide unit 41A, with the position of elastomeric element 84 subtends on, form claw shape 83.For example, elastomeric element of being made up of leaf spring 84 and the claw shape 83 of slide unit 41A when slide unit 41A moves to from the 1st position when occupying the 2nd position, constitute the chimeric sense means that have chimeric sense.
When slide unit 41A when the 1st position moves to the 2nd position, the claw shape 83 of slide unit 41A surmounts elastomeric element 84.Thus, obtain click (Network リ Star Network) sense, operation sense improves.
As shown in figure 26, when slide unit 41A occupied the 2nd position by above-mentioned chimeric sense means, the gap of elastomeric element 84 and claw shape 83 became below the 2mm.Take this, can eliminate the loosening of slide unit 41A horizontal direction.
Secondly, and, the action of the positioning unit 70 of the 1st example is described mainly,, thin portion is constituted also do suitable supplementary notes though there is part to repeat with Figure 32 and Figure 33.
As Fig. 3 explanation, then Figure 32 is the figure that expression will be located holding member 32A appearance when being positioned at institute's Dingan County's holding position.Specifically, the inboard that each cartridge processing 1Y to 1BK is clamp-oned image forming device body, to locate holding member 32A and turn to make-position, make at the pilot hole 35a, the 35b that form on the holding member 32A of this location and be entrenched on register pin 35a, the 35b that is convexly set on the front side board 28 (with reference to Fig. 2 and Fig. 3), thereby, will locate holding member 32A and be positioned on institute's Dingan County's holding position.As comparative example, as Fig. 2 explanation, Figure 32 then is the view of this figure arrow IV direction.From Figure 32 and Figure 33 etc. as can be known, in the holding member 32A of location, disposed slide unit 41A.
On slide unit 41A, form a plurality of slotted holes 42 in the horizontal direction, in this each slotted hole 42, insert the band stepped screw 43 that can slide relatively, this respectively is with stepped screw 43 to be screwed onto on the holding member 32A of location.Take this, slide unit 41A can prop up and be held on the holding member 32A of location movably making horizontal direction between shown in figure 32 the 1st position and the 2nd position as shown in figure 33.
Swing to shown in figure 32 make-position if will locate holding member 32A from above-mentioned open position, then each bearing 17 is embedded into and is formed in each mounting hole 77 of locating on the holding member 32A.At this moment, as shown in Figure 32, the size of each mounting hole 77 is set less than each supporting axis 16 and the cross-sectional area that cooperates each bearing 17 in it, and each bearing 17 can embed in each mounting hole 77 by bigger play.Therefore, can like a cork each bearing 17 be embedded in each mounting hole 77.
On the other hand, be provided with each push part 44A respectively corresponding to each bearing 17.Each push part 44A is when slipping, being directed with respect to slide unit 41A and guide surface 50, and the lancing shape 41a that is also embedded in the slotted hole 44b guides, can move in the horizontal direction fixed stroke.
As previously mentioned, on the lancing shape 41a of the lancing shape 44a of each push part 44A and slide unit 41A, card each end of ending U font spring 71 respectively.Take this, each push part 44A by attached with the potential energy right-hand in Figure 32, but when slide unit 41A occupies shown in figure 32 the 1st position, as shown in figure 10, because the tax potential energy power of spring 71, the punching press base portion of the lancing shape 41a of slide unit 41A are connected to the right part among the figure of push part 44A slotted hole 44b, play the effect of brake block, take this, each push part 44A stops at position shown in figure 32.At this moment, each push part 44A does not contact each bearing 17 of each mounting body holding components 15.
Like this, each push part 44A is under the state of being composed with potential energy by spring 71, removable is held in slide unit 41A, when slide unit 41A is in the 1st position, compose with the push part 44A behind the potential energy through spring, be subjected to being located at the restriction of slide unit 41A lancing shape 41a, forbid contacting mounting body holding components 15.Therefore, the operator is by manual operation, and when location holding member 32A was swung to shown in figure 32 make-position from above-mentioned open position, each bearing 17 can not disturb each push part 44A, and embeds in each mounting hole 77.
Secondly, the operator resists the potential energy of four springs 71 and each push part 44A making a concerted effort for the friction resistibility of the slip slide connecting part of slide unit 41A etc., by as Figure 14 and the rotary manipulation to control lever 90 shown in Figure 16, slide into slide unit 41A shown in figure 32 right-hand, occupy the 2nd position as shown in figure 33, then the wedge-shaped part 53 of each push part 44A is pressed between each bearing 17 of guide surface 50 and each mounting body holding components 15, each bearing 17 is pressed on two faces 78,79 of each mounting hole 77.Below illustrate in greater detail the effect of this moment.
If slide unit 41A is begun to move from shown in figure 32 the 1st position towards as shown in figure 33 the 2nd position, then compose with potential energy by each spring 71, and by each push part 44A of the lancing shape 41a restriction that is embedded into slotted hole 44b, with slide unit 41A, begin to shift to right-hand among Figure 32.Next, arrive institute's allocation between the 1st position and the 2nd position as slide unit 41A, then by the wedge-shaped part 53 of each spring 71 tax with each push part 44A of potential energy, be pressed between each bearing 17 of guide surface 50 and each mounting body holding components 15 outer peripheral face of each bearing 17 of crimping and stopping.Take this, each push part 44A does the brute force pushing of two faces 78,79 of each mounting hole 77 relatively to each bearing 17.
After each push part 44A stops, if resist the potential energy of each spring 71, slide unit 41A is moved, then each end of the slotted hole 44b that on each push part 44A, forms towards the 1st position, leave each lancing shape 41a, remove the restriction of each lancing shape 41a each push part 44A.
As implied above, because compose by each spring 71 wedge-shaped part 53 with each push part 44A of potential energy form pushing force under usefulness, each bearing 17 is crimped on two faces 78,79 of each mounting hole 77, so the front part of each photoconductor drum 6Y to 6BK of each mounting body holding components 15 and these parts of support can be made correct positioning for location holding member 32A.At this moment, as Fig. 2 and Fig. 3 explanation, then because this location holding member 32A can be properly oriented with respect to framework 33, so final each photoconductor drum 6Y to 6BK can be properly oriented with respect to the framework 33 of image forming device body 7.As long as the operator will locate holding member 32A be installed in respect to framework 33 in the fixed position, operation control lever 90, mobile slide unit 41A just can locate each photoconductor drum 6Y to 6BK with respect to image forming device body 7.And, because the size of the mounting hole 77 that forms at location holding member 32A can be set more greater than the cross-sectional area of the anterior end of mounting body holding components 15, so each mounting body holding components 15 can be embedded in each mounting hole 77 like a cork.
Certainly, with respect to the interval of two faces 78,79 of each mounting hole 22 of the dimensional accuracy of the location holding member 32A of framework 33 and location holding member 32A and the dimensional accuracy of each one, much less all to be set in to making each photoconductor drum 6Y to 6BK with respect in the fixed accuracy rating (tolerance) in image forming device body 7 location.
As mentioned above, push part means main composition is as follows: can be provided with corresponding to each mounting body holding components 15, and each maintaining part (two faces 78,79) on a plurality of push part 44A of moving between for non-contacting non-pushing position and pushing position that each the mounting body holding components 15 on each maintaining part (two faces 78,79) is pushed, locatees of each mounting body holding components 15; As the spring 71 of the means of energizing, each push part 44A is composed with potential energy towards moving it the pushing locality; In the time of each push part 44A of removable support, propping up the single slide unit 41A that is held in location holding member 32A movably corresponding to the 1st position of non-pushing position with between corresponding to the 2nd position that pushes the position; Make slide unit 41A be displaced into mobile means 92 between the 1st position and the 2nd position.
According to the 1st example, constitute according to above-mentioned each, can obtain to be better than the operability of comparative example, the effect that cost is cheaper.And even at the 1st example, the position of each inscape etc. is also set for and can be carried out following action.That is to say, when slide unit 41A is in the 1st position, compose each push part 44A with potential energy by each U font spring 71 and be subjected to restriction as each lancing shape 41a of the detent of slide unit 41A, being under an embargo contacts with each mounting body holding components 15 on each two face 78,79.When slide unit 41A from the 1st position when move the 2nd position, compose with potential energy by each U font spring 71, and move with slide unit 41A by each push part 44A of each lancing shape 41a restriction.When slide unit 41A arrived between the 1st position and the 2nd position position, by each push part 44A that each U font spring 71 is composed with potential energy, its wedge-shaped part 53 was pressed between each mounting body holding components 15 on guide surface 50 and each two face 78,79 and stops.By slide unit 41A is further moved to the 2nd position, position to slide unit 41A, each push part 44A, each U font spring 71 and each lancing shape 41a is set, so that each push part 44A removes down from the restriction of each lancing shape 41a.
According to this example, same with above-mentioned comparative example, when allowing slide unit 41A occupy as shown in figure 33 the 2nd position, because the wedge-shaped part 53 of each push part 44A is pressed between the outer peripheral face of guide surface 50 and each bearing 17, be subjected to the effect of its friction force and spring 71 potential energy of composing, each mounting body holding components 15 is remained on the regular position, can make each photoconductor drum 6Y to 6BK continue to be able to correct location.In addition, if by manual operation slide unit 41A, return the 1st position shown in figure 32 once more, then because each push part 44A from the outer peripheral face disengaging of each bearing, therefore can swing to location holding member 32A open position as shown in Figure 3 without barrier.
According to this example, except the aforementioned characteristic formation of this example, much less the part as above-mentioned comparative example formation about it had has the advantage as above-mentioned comparative example, also can bring into play same effect.
Figure 27 to Figure 29 represents the variation 1 of the 1st example.This variation 1 is compared with the 1st example, and main difference is that it has the maintenance of the push part that can improve band wedge-shaped part 53 and the formation of sliding capability.That is, replace the push part 44A that constitutes the pushing means except using push part 44B, other are identical with the 1st example.
As the 1st example,, the slide unit 41A of horizontal slip is set with respect to not giving illustrated location holding member 32A among Figure 27 to Figure 29.On this slide unit 41A, be formed with lancing shape 41a as the 1st fastener.On push part 44B with conical wedge-shaped part 53, be formed with lancing shape 41a direction with slide unit 41A opposite, as the lancing shape 44a and the slotted hole 44b of the 2nd fastener.And, slide unit 41A and push part 44B, chimeric shown in the arrow of Figure 27.Slide unit 41A and push part 44B as shown in figure 28, set separately lancing shape 41a and 41b subtend each other respectively for.
At lancing shape 41a and 41b each other, mounting both ends 71a, the 71b of the spring 71 of U font.By the elastic force of this spring 71, push part 44B remains in slide unit 41A relatively, is applied with tension force between push part 44B and the slide unit 41A.
Close the position of the lancing shape 44a above-below direction of the lancing shape 41a of slide unit 41A and push part 44B: the lancing shape 44a of push part 44B is positioned at the top of the lancing shape 41a of slide unit 41A with respect to wedge surface.
In Figure 29, demonstrated the assembled state of slide unit 41A, push part 44B and spring 71.Here, the lancing shape 44a of push part 44B is with respect to wedge surface, be positioned at the top of the lancing shape 41a of slide unit 41A, thus, the power of the direction of arrow of this figure is worked, push part 44B is contacted with the guide surface 50 of slide unit 41A, make push part 44B vertically keep stable posture.
Figure 30 and Figure 31 represent the variation 2 of variation 1.This variation 2 is compared with variation 1, and main difference is to use push part 44C to substitute push part 44B, and other are as variation 1.
The slide unit 41A of push part 44C and the contact site of guide surface 60 contact with the top both ends of push part 44C.Thus, because of the contact area of push part 44C and slide unit 41A diminishes, can reduce the horizontal friction when mobile of push part 44C.
In addition, as shown in figure 30, the shape at the top both ends of push part 44C is not circular-arc, but the contact of the substantial line of the shape 44c that is in line.Therefore, for example shown in Figure 29, slide unit 41A does laterally to slide, in the time of the bearing 17 of push part 44C pushing photoconductor drum, even produce the power of arrow U direction, because the contact site of push part 44C is a rectilinear form, push part 44C can not eat in the guide surface 50 that enters slide unit 41A and go, so that the action of push part 44C becomes is level and smooth.
In addition, as Figure 30 and shown in Figure 31, at the circular-arc protruding 44d that is formed with on the push part 44 more than 3.Take this, because protruding 44d becomes point to contact with the web face 41c of slide unit 41A, so, can realize the more level and smooth action of push part 44C with respect to slide unit 41A.
According to the 1st above-mentioned example, variation 1 and 2 etc., one is characterised in that, it improved in comparative example shown in Fig. 1 to 7, for location, the hold mode of each mounting body holding components 15 mounting hole 37.But, in the 1st example, variation 1 and 2 etc.,, unfavorable condition as described below was arranged also though be few.That is, not exclusively contact under the state of each face 78,79 of locating holding member 32A at bearing 17, if slide unit 41A enters the 2nd position, then the position of supporting axis (rotating shaft 16) will be in irregular state and be fixed.
At this, just removed the following variation 3 to 6 of above-mentioned unfavorable condition fully and done an explanation.
