Utilize this structure, whether user etc. can correctly close by inspection cover unit 610,620,630 and 640 is confirmed whether developing cell has been installed to correct attaching/detaching part.
As mentioned above, can realize user-friendly printer 10, because user etc. can be easily and do not produced setup error ground developing cell is installed to the attaching/detaching part by above-mentioned cap unit 610,620,630 and 640 being set, becoming.
Other considerations of===(1)===
In the aforementioned embodiment, the container installing mechanism comprises a plurality of opening/closable cap unit 610,620,630 and 640, each cap unit all is connected among attaching/detaching part 50a, 50b, 50c and the 50d separately one, and allows developing cell to be installed to the attaching/detaching part by being closed.As Fig. 8 and shown in Figure 9.In addition, when black developing cell 51 was inserted among four attaching/detaching part 50a, 50b, 50c and the 50d any, cap unit 610,620,630 and 640 was closed.On the other hand, only when cyan developing cell 52 was inserted into attaching/detaching part 50b, cap unit 620 was closed; Only when magenta developing cell 53 was inserted into attaching/detaching part 50c, cap unit 630 was closed; And and if only if yellow developing cell 54 when being inserted into attaching/detaching part 50d, cap unit 640 is closed.
But this structure is not limited to above.For example, the container installing mechanism can be attaching/detaching part 50a, 50b, 50c and 50d.In the case, must in attaching/detaching part 50a, 50b, 50c and 50d, cut-out be set.
But, constitute under the situation of container installing mechanism at cap unit 610,620,630 and 640, can whether close by inspection cover unit 610,620,630 and 640 and confirm that whether developing cell has been installed to correct attaching/detaching part, can realize more user-friendly printer 10 thus.Therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, as shown in Figure 8, each developing cell 51,52,53 and 54 is provided with first rib 581K, 581C, 581M and 581Y and second rib 582C, 582M and 582Y (jut), and be connected among four attaching/detaching part 50a, 50b, 50c and the 50d each cap unit 610,620,630 and 640 each all have first cut-out 617,627,637 and 647 and second cut-out 628,638 and 648, be used to prevent the interference of first rib and this cap unit, thereby this cap unit will be closed.When black developing cell 51 was inserted among four attaching/detaching part 50a, 50b, 50c and the 50d any, cap unit was closed with cap unit 610,620,630 and 640 first cut-outs of interfering owing to preventing.On the other hand, only when cyan developing cell 52 is inserted into attaching/detaching part 50b, cap unit 620 is owing to preventing that first cut-out 627 and second cut-out 628 of interfering with cap unit 620 from closing; Only when magenta developing cell 53 is inserted into attaching/detaching part 50c, cap unit 630 is owing to preventing that first cut-out 637 and second cut-out 638 of interfering with cap unit 630 from closing; And and if only if yellow developing cell 54 when being inserted into attaching/detaching part 50d, cap unit 640 is owing to preventing that first cut-out 647 and second cut-out 648 of interfering with cap unit 640 from closing.
But this structure is not limited to above.For example, cut-out can be arranged in developing cell 51,52,53 and 54, and first rib can be arranged on cap unit 610,620,630 and 640.
In addition, in the aforementioned embodiment, as shown in Figure 8, four attaching/detaching part 50a, 50b, 50c and 50d comprise with cyan developing cell 52 corresponding attaching/detaching part 50b, with magenta developing cell 53 corresponding attaching/detaching part 50c and with yellow developing cell 54 corresponding attaching/detaching part 50d; And first rib 581K, 581C, 581M and 581Y are different between developing cell 51,52,53 and 54.In addition, be connected to attaching/detaching part 50a, 50b, 50c and 50d all cap units 610,620,630 and 640 each all have first cut-out 617,627,637 and 647, the first rib 581K and this cap unit that are used to prevent to be arranged on the black developing cell 51 are interfered; And be connected to attaching/detaching part 50b, 50c and 50d cap unit 620,630 and 640 each all have second cut-out 628,638 and 648, be used for preventing being arranged on cyan developing cell 52, magenta developing cell 53 and yellow developing cell 54 first rib 581C, 581M and 581Y and this cap unit on each and interfere.But this structure is not limited to above.
But, utilize above structure, can allow black developing cell 51 to be installed among four attaching/detaching part 50a, 50b, 50c and the 50d any more reliably, and allow cyan developing cell 52, magenta developing cell 53 and yellow developing cell 54 only to be installed to predetermined attaching/detaching part more reliably.Therefore previous embodiment is preferred.
In addition, in the present embodiment, as shown in Figure 8, each in cyan developing cell 52, magenta developing cell 53 and the yellow developing cell 54 all be arranged on black developing cell 51 on the identical position of first rib 581K have second rib 582C, 582M and 582Y.But this is not restriction.For example, cyan developing cell 52, magenta developing cell 53 and yellow developing cell 54 not necessarily will be provided with second rib.
But, if not being set, second rib and first rib 581C, 581M and 581Y be not arranged in close each other position, then because the deviation during closing cap unit 620,630 and 640 etc. cause these first ribs not interfered with cap unit, developing cell may be installed mistakenly.On the other hand, by on cyan developing cell 52, magenta developing cell 53 and yellow developing cell 54 second rib 582C, 582M and 582Y being set, first rib 581C, the 581M that is arranged in second rib 582C, 582M and the 582Y of same position and is arranged in the position that differs from one another is different with distance between the 581Y.Therefore, becoming to prevent effectively that developing cell from being installed mistakenly, though cap unit 620,630 and 640 when closing not at correct position.Therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, as shown in figure 10, cap unit 640 (610,620,630) has the coupling part 644 (614,624,634) that is connected to attaching/detaching part 50d (50a, 50b, 50c), and the coupling part can be able to be opened/can be closed as axle; And the distance X 1 between coupling part 644 (624,634) and first cut-out 647 (627,637) can be greater than the distance X 2 between coupling part 644 (624,634) and second cut-out 648 (628,638).But this is not restriction.For example, distance X 1 can be less than distance X 2.
But, if developing cell 52,53 and 54 be inserted into mistakenly except that its predetermined attaching/detaching part the attaching/detaching part (for example, if cyan developing cell 52 is inserted into attaching/detaching part 50d mistakenly), then first rib 581C will interfere with cap unit 640.If the user attempts to close cap unit 640 under first rib 581C and cap unit 640 interferes therein the state, then load will be applied to the periphery of coupling part 644.If this load is very big, then cap unit 640 may rupture.Therefore, preferably reduce to be applied to the load of coupling part 644 peripheries under the situation of attaching/detaching part at developing cell 52,53 and 54 misplugs.Compare during less than distance X 2 with distance X 1, by making distance X 1 greater than distance X 2, becoming to reduce to be applied to the load of coupling part 644 peripheries at developing cell 52,53 and 54 misplugs under the situation of attaching/detaching part.Therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, as shown in figure 10, when closing, cap unit 640 (610,620,630) cooperates with developing cell 54 (51,52,53) and is fastened to it at restraint location; And the distance Y 1 between restraint location and first cut-out 647 (627,637) is less than the distance Y 2 between restraint location and second cut-out 648 (628,638).But this is not restriction.For example, distance Y 1 can be greater than distance Y 2.
But, if developing cell 52,53 and 54 be inserted into mistakenly except that its predetermined attaching/detaching part the attaching/detaching part (for example, if cyan developing cell 52 is inserted into attaching/detaching part 50d mistakenly), then when first rib 581C and cap unit 640 interfered, will between the mating part 642a of lock pin 642 and sidewall 580C, produce the gap.Compare during with distance Y 1 greater than distance Y 2, when distance Y 1 during less than distance Y 2 size in gap bigger.This be because when 640 interference of first rib 581C and cap unit cap unit 640 elastic deformations, and deflection becomes big more, then mating part 642a is far away more from interference position.Therefore, under the very big situation in gap, promptly therein under the situation of distance Y 1 less than distance Y 2, becoming to prevent effectively that lock pin 642 mistakes are coupled to sidewall 580C.Therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, developer reservoir is each developing cell 51,52,53 and 54 (developing apparatuses) of all being provided with developer roll 510 (developer carrier), and this developer roll 510 is used to carry the toner that development is carried on the sub-image on the photoreceptor 20, as shown in Figure 5.But this is not restriction.For example, developer reservoir not necessarily will be provided with developer roll 510, and can be the box that holds the toner that will be fed to developing cell 51,52,53 and 54.
For example when holding toner quantitative change little and/or when developer roll 510 is damaged, carry out from the dismounting of attaching/detaching part.Therefore, be that the situation of box is compared with developer reservoir wherein, the frequency that developer reservoir is installed to the attaching/detaching part when developer reservoir is developing cell 51,52,53 and 54 is higher.Consider the effect that can more advantageously reach present embodiment, promptly can realize the effect of user friendly printer 10, therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, the developer of particular color is black toner (black reagent).But this is not restriction, and for example the developer of particular color can be any in cyan toner, magenta toner and the Yellow toner.In these cases, printer 10 will form the monochrome image of this color.
But the frequency of using black toner to form monochrome image is higher than the frequency that forms colored monochrome image.Therefore, be installed to four attaching/detaching part 50a, 50b, 50c and 50d by the black developing cell 51 that allows to hold black toner, becoming to form a large amount of monochrome images, realizes more user-friendly printer 10 thus.Therefore previous embodiment is preferred.

Figure 18 A to 18C is the view of three stop positions that the developing cell grip unit 2050 of rotation is shown.Figure 18 A shows original position (below be called " HP position "), and it is the position of readiness when printer waits for that carries out image forms, and it is still as the stop position of the reference position on developing cell grip unit 2050 sense of rotation.Figure 18 B shows connector attaching/detaching position, and the developing cell side-connector 2054b of yellow developing cell 2054 that is installed to developing cell grip unit 2050 at this place is relative with the device side connector 34 that is positioned at device side.Figure 18 C shows the attaching/detaching position of the yellow developing cell 2054 of installation and removal.
In Figure 18 B and Figure 18 C, at yellow developing cell 2054 explanation connector attaching/detaching position and developing cell attaching/detaching positions, but these positions become in other developing cells each connector attaching/detaching position and developing cell attaching/detaching position during with 90 ° spacing rotation in developing cell grip unit 2050.
At first, will the HP position shown in Figure 18 A be described.It is distolateral that the HP detecting device 31 (Fig. 3) that is used to detect the HP position is arranged on the turning axle 2050e one of developing cell grip unit 2050.HP detecting device 31 is made of a dish and HP sensor, and described dish is used to produce signal and is fixed to the end of turning axle 2050e, and the HP sensor is made up of the optical interruption device that for example has luminous component and light receiving part.The outer peripheral portion of dish is arranged between the luminous component and light receiving part of HP sensor.When the slit in being formed on dish moved to the detection position of HP sensor, the signal of exporting from the HP sensor changed to " H " from " L ".This equipment is configured to like this, detects the HP position of developing cell grip unit 2050 with the umber of pulse based on this variation in the signal level and pulse motor, and by with this HP position as a reference, each developing cell can be positioned developing location etc.
Figure 18 B shows the connector attaching/detaching position by the yellow developing cell of the predetermined umber of pulse of pulse motor rotation being realized from above-mentioned HP position 2054.In this connector attaching/detaching position, the developing cell side-connector 2054b of yellow developing cell 2054 that is installed to developing cell grip unit 2050 is relative with the device side connector 34 that is positioned at device side, and becomes and can connect or separate these connectors.
Utilize Figure 19 A and Figure 19 B to provide further instruction.Figure 19 A shows the view of separation point position, and the developing cell side-connector 2054b and the device side connector 34 of wherein yellow developing cell 2054 are separated from one another.Figure 19 B shows the view of rest position, and the developing cell side-connector 2054b and the device side connector 34 of wherein yellow developing cell 2054 abut against each other.
Figure 19 A shows the developing cell side-connector 2054b of wherein yellow developing cell 2054 and device side connector 34 state separated from one another.Device side connector 34 be configured to its can towards with leave yellow developing cell 2054 and move.Where necessary, device side connector 34 is gone up in the direction (direction of arrow shown in Figure 19 B) towards yellow developing cell 2054 and is moved.Like this, device side connector 34 shown in Figure 19 B against the developing cell side-connector 2054b of yellow developing cell 2054.So the developing cell side storer 2054a that is installed to yellow developing cell 2054 is electrically connected to the cell controller 102 of control module 100, and set up developing cell side storer 2054a and the device between communication.
On the contrary, device side connector 34 is from the state that abuts against each other of the developing cell side-connector 2054b of device side connector 34 and yellow developing cell 2054 wherein shown in Figure 19 B, the direction of leaving yellow developing cell 2054 (with the side of arrow shown in Figure 19 B in the opposite direction) go up and move.Like this, device side connector 34 separates with the developing cell side-connector 2054b of yellow developing cell 2054, shown in Figure 19 A.

===(2) installation developing cell===
The process that developing cell is installed to the attaching/detaching part is described here.
Carry out the installation of developing cell 2051,2052,2053 and 2054 in the same manner, the therefore following process that yellow developing cell 2054 is installed to attaching/detaching part 2050d of only describing.
Yellow developing cell 2054 is installed to attaching/detaching part 2050d is positioned at the attaching/detaching position of yellow developing cell 2054 from developing cell grip unit 2050 wherein state.Supposing does not currently have developing cell to be installed to attaching/detaching part 2050d and provides following explanation.
At first, the user waits and opens developing cell capping 2641.Then, user etc. compare the color of lock pin 2642 and the color of sidewall 2580Y, and judge whether yellow developing cell 2054 is the developing cells that can be installed to attaching/detaching part 2050d.Herein, because the color of the color of lock pin 2642 and sidewall 2580Y all is yellow, so the yellow developing cell 2054 of judgements such as user can be installed to attaching/detaching part 2050d.Should be noted that black developing cell 2051 can be installed to all four attaching/detaching part 2050a, 2050b, 2050c and 2050d, thereby such judgement has not just needed.
Then, the user waits yellow developing cell 2054 is inserted among the attaching/detaching part 2050d.For example, user etc. are holding handle 2590Y, and yellow developing cell 2054 is inserted among the attaching/detaching part 2050d by attaching/detaching dedicated openings 37.
Then, rotation developing cell capping 2641 such as user is to close it.Because first cut-out 2647 be arranged on the corresponding position of second rib 2582Y in and second cut-out 2648 be arranged on the corresponding position of first rib 2581Y in, so first rib 2581Y and second rib 2582Y will not interfere with developing cell capping 2641 when rotating.When developing cell capping 2641 is rotated scheduled volume, first rib 2581Y and second rib 2582Y not with the situation of its interference under, lock pin 2642 cooperates with sidewall 2580Y.Lock pin 2642 is coupled to sidewall 2580Y to be caused developing cell capping 2641 to cooperate with sidewall 2580Y and is fastened to it, thereby developing cell capping 2641 is closed.
On the other hand, developing cell capping 2641 will not closed when cyan developing cell 2052 or magenta developing cell 2053 are inserted among the attaching/detaching part 2050d.For example, as shown in figure 27, if cyan developing cell 2052 is inserted among the attaching/detaching part 2050d, then developing cell capping 2641 will not closed, because the position of second cut-out 2648 not with the corresponding position of first rib 2581C in, thereby first rib 2581C and developing cell capping 2641 interfered.Should be noted that Figure 27 shows wherein when cyan developing cell 2052 is inserted among the attaching/detaching part 2050d not closing state of developing cell capping 2641.
The function of===(2) cap unit===
As mentioned above, boundary portion office between cap unit and developing cell, each cap unit 2610,2620,2630 that printer 10 (image processing system) upward is provided with and 2640 color are different from the color of each developing cell 2051,2052,2053 and 2054 (developer reservoirs).Utilize this structure, become and to realize allowing correctly to dismantle the printer 10 of developing cell from the attaching/detaching part.This is discussed in more detail below.
In printer 10 with photoreceptor 20 (image carrier), attaching/detaching part 2050a, 2050b, 2050c and 2050d and cap unit 2610,2620,2630 and 2640, such situation is arranged, from allowing user wait to distinguish the angle that is contained in the toner color developing cell 2051,2052,2053 and 2054, developing cell 2051,2052,2053 and 2054 to be painted to have and the identical color of color of each toner that holds wherein.For example, such situation is arranged, the sidewall 2580Y that wherein holds the developing cell 2054 of Yellow toner is painted to has the color (yellow) identical with the toner color.In addition, such situation is arranged, wherein from allowing correct developing cell is installed to the angle of attaching/detaching part 2050a, 2050b, 2050c and 2050d, with the preceding face colouring of each cap unit 2610,2620,2630 and 2640.
Under these situations, if the boundary portion office between cap unit and developing cell, the color of cap unit 2640 (2610,2620,2630) is identical with the color of developing cell 2054 (2051,2052,2053), such possibility is then arranged, be that user etc. may be identified as cap unit the part of developing cell improperly, and may attempt state that cap unit therein still covers developing cell part dismounting developing cell down.This may be in the damage of attempting to cause cap unit when attaching/detaching is partly dismantled developing cell.
Be explained in more detail.Herein, the color of supposing the developing cell capping 2641 of cap unit 2640 is yellow, and identical with the color (yellow) of the sidewall 2580Y of developing cell 2054.In the case, the boundary portion office between sidewall 2580Y and capping 2641, the color of developing cell capping 2641 is identical with sidewall 2580Y's.Because developing cell capping 2641 covers the part (i.e. part except that handle 2590Y) of sidewall 2580Y, so if the color of developing cell capping 2641 is identical with the color of sidewall 2580Y, then user etc. may be identified as developing cell capping 2641 part of sidewall 2580Y improperly, and may attempt at developing cell capping 2641 dismounting developing cell 2054 under the closing state still.As mentioned above, under 2641 closing state of developing cell capping therein, lock pin 2642 does not also unclamp with respect to the cooperation of developing cell 2054.Therefore, if dismantle developing cell 2054 under the situation of the cooperation of not unclamping lock pin 2642, then cap unit 2640, i.e. any in developing cell capping 2641, lock pin 2642 and the action button 2643 may rupture.
Consider abovely, in the present embodiment, the boundary portion office between cap unit and developing cell makes the color of the color of cap unit 2640 (2610,2620,2630) and developing cell 2054 (2051,2052,2053) inequality, as shown in figure 20.Like this, user etc. can distinguish developing cell and cap unit.
This utilizes yellow developing cell 2054 and cap unit 2640 to describe in more detail.As mentioned above, developing cell capping 2641 covers the part of the sidewall 2580Y of yellow developing cell 2054, and boundary member is the part of developing cell capping 2641.Like this, in the boundary portion office with respect to sidewall 2580Y, the color of developing cell capping 2641 (Dark grey) is different from the color (yellow) of sidewall 2580Y, and user etc. can distinguish developing cell capping 2641 and comes with sidewall 2580Y.Therefore, user etc. will open developing cell capping 2641, promptly unclamp the cooperation of lock pin 2642 with respect to sidewall 2580Y, and dismantle developing cell 2054 subsequently.The result, can prevent suitably that yellow developing cell 2054 still is developed under the state that unit capping 2641 covers in its part is disassembled, thereby can prevent the damage of cap unit (developing cell capping 2641, lock pin 2642 and action button 2643) when dismantling yellow developing cell 2054 from attaching/detaching part 2050d.
As mentioned above, by cap unit 2610,2620,2630 and 2640 is set according to present embodiment, user etc. can distinguish cap unit and developing cell.Therefore, can prevent that developing cell from partly dismantling from attaching/detaching under its state that is still covered by cap unit, can realize allowing correctly partly to dismantle the printer 10 of developing cell from attaching/detaching thereby become.
Other considerations of===(1)===
In the aforementioned embodiment, as shown in figure 20, cap unit 2640 (2610,2620,2630) covers the part of the sidewall 2580Y (2580K, 2580M, 2580C) of the developing cell 2054 (2051,2052,2053) that is installed to attaching/detaching part 2050d (2050a, 2050b, 2050c), and in the boundary portion office of cap unit and sidewall, the color of cap unit is different from the color of sidewall (oppose side wall 2580Y is yellow).But this is not restriction.For example, cap unit 2640 (2610,2620,2630) can cover the part except that sidewall 2580Y (2580K, 2580M, 2580C).
In addition, in the aforementioned embodiment, as shown in figure 16, sidewall 2580Y (2580K, 2580M, 2580C) be provided with handle 2590Y (2590K, 2590M, 2590C) and sidewall by cap unit 2640 (2610,2620,2630) cover that part of be part except that handle.But this is not restriction.For example, cap unit 2640 (2610,2620,2630) can cover handle 2590Y (2590K, 2590M, 2590C).
If handle 2590Y is covered by cap unit 2640, then user waits and will think and just must open cap unit 2640 in order to dismantle developing cell 2054.On the other hand, if handle 2590Y is not covered by cap unit 2640, even then user etc. may think improperly that cap unit 2640 is closed also and can dismantle developing cell 2054.In the case, cap unit 2640 impaired possibilities become very high.Therefore, the part that covered by cap unit 2640 of sidewall 2580Y is under the situation of the part except that handle 2590Y therein, can more advantageously reach the effect of present embodiment, promptly can realize allowing from the correct effect of dismantling the printer 10 of developing cell of attaching/detaching part.Therefore previous embodiment is preferred.
In addition, in the aforementioned embodiment, as shown in figure 22, cap unit 2640 (2610,2620,2630) has the developing cell capping 2641 (2611,2621,2631) that covers sidewall 2580Y (2580K, 2580M, a 2580C) part, and described developing cell capping has the coupling part 2644 (2614,2624,2634) that is connected to attaching/detaching part 2050d (2050a, 2050b, 2050c) and the coupling part can opened/can closed under as the situation of axle.In addition, boundary member is the part of developing cell capping 2641 (2611,2621,2631); And the color of developing cell capping (Dark grey) is different from the color (oppose side wall 2580Y is yellow) of sidewall 2580Y (2580K, 2580M, 2580C).But this is not restriction.For example, the color of the boundary member of developing cell capping 2641 (2611,2621,2631) can be a Dark grey, and the color of the part except that the part of border can be and the identical color of sidewall 2580Y (2580K, 2580M, 2580C).
But, compare when being different from the color of sidewall 2580Y with color when the boundary member that has only developing cell capping 2641, when the color (Dark grey) of whole developing cell capping 2641 is different from the color (yellow) of sidewall 2580Y, developing cell capping 2641 is distinguished with sidewall 2580Y come easily.Therefore, the color of developing cell capping therein 2641 is different under the situation of color of sidewall 2580Y, becomes can prevent to be disassembled under developing cell 2054 state that the part of sidewall 2580Y is still covered by cap unit 2640 therein.

In addition, as Figure 31 and shown in Figure 32, attaching/detaching part 3050a has connected the cap unit 3610 that is used for attaching/detaching part 3050a to it; Attaching/detaching part 3050b has connected the cap unit 3620 that is used for attaching/detaching part 3050b to it; Attaching/detaching part 3050c has connected the cap unit 3630 that is used for attaching/detaching part 3050c to it; And attaching/detaching part 3050d has connected the cap unit 3640 that is used for attaching/detaching part 3050d to it.In the cap unit 3610,3620,3630 and 3640 each can be opened and closed separately, and when this developing cell is inserted in the attaching/detaching part and in cap unit 3610,3620,3630 and 3640 corresponding one when being closed, each developing cell becomes available.Herein, cap unit 3610,3620,3630 and 3640 corresponding settings with each developing cell, these developing cells will be installed to attaching/detaching part 3050a, 3050b, 3050c and the 3050d that these cap units 3610,3620,3630 and 3640 are connected respectively to.Cap unit is configured to like this, and promptly it can be closed when the developing cell 3051,3052,3053 that should install and 3054 are installed, and it can't be closed when developing cell that installation should not be installed.
The detailed structure of===(3) cap unit===
The detailed structure of cap unit is described below.
At first, description is connected to the structure of the cap unit 3640 of attaching/detaching part 3050d.Figure 33 is the view from the observed cap unit 3640 in the outside of printer 10 (the place ahead).Figure 34 is the rear view of cap unit 3640.
Developing cell capping 3641 has two coupling parts 3644 that are connected to attaching/detaching part 3050d and are spaced apart from each other.Two coupling parts 3644 are supported by attaching/detaching part 3050d, and cap unit 3640 is configured to and can rotates around the rotation axis CL that passes these two coupling parts 3644.In other words, cap unit 3640 is connected to attaching/detaching part 3050d by hinge 3057Y, and hinge 3057Y is made of the member of coupling part 3644 and their attaching/detaching part 3050d of support.Should be noted that the color of developing cell capping 3641 is different from the color of sidewall 3580Y (yellow).
In addition, developing cell capping 3641 is provided with first cut-out 3647, second cut-out 3648 and the 3rd cut-out 3649, and these cut-outs are as mating part.First cut-out 3647 is used to prevent second rib 3582Y and developing cell capping 3641 interference.Second cut-out 3648 is used to prevent first rib 3581Y and developing cell capping 3641 interference.The 3rd cut-out 3649 is used to prevent the 3rd rib 3583Y and developing cell capping 3641 interference.In other words, first cut-out 3647 be arranged on the corresponding position of second rib 3582Y in, second cut-out 3648 be arranged on the corresponding position of first rib 3581Y in, the 3rd cut-out 3649 be arranged on the corresponding position of the 3rd rib 3583Y in.Like this, when being inserted among the attaching/detaching part 3050d as the yellow developing cell 3054 that should be installed to the developing cell of attaching/detaching part 3050d, first cut-out 3647, second cut-out 3648 and the 3rd cut-out 3649 prevent that first rib 3581Y, second rib 3582Y and the 3rd rib 3583Y and developing cell capping 3641 from interfering, and allows developing cell capping 3641 to close (referring to Figure 31) thus.
More specifically, by cooperating of first rib 3581Y and second rib 3582Y and second cut-out 3648 and first cut-out 3647, can distinguish that indication holds the information of toner color in the developing cell, first cut-out 3647 and second cut-out 3648 be arranged in respectively with the second rib 3582Y and the corresponding position of first rib 3581Y that are provided with according to holding the color of toner in the developing cell in.On the other hand, by cooperating of the 3rd rib 3583Y and the 3rd cut-out 3649, distinguish the information about developing cell and toner destination, the 3rd cut-out 3649 is correspondingly arranged with the 3rd rib 3583Y that is provided with according to the destination.For example, realize utilizing the 3rd rib 3583Y and the 3rd cut-out 3649 to distinguish the method for the information of indication destination as follows.Figure 35 is the view that the model that is used to illustrate example how to use the 3rd rib to distinguish destination information is shown., be described based on such example, above-mentioned the 3rd rib indication " Japan " and will a kind of like this 3rd rib in this example and be provided with indication " Europe " and distinguish out as the developing cell of the information of another destination as the destination in this example herein.
For example, with holding its destination is that above-mentioned the 3rd rib (being illustrated by solid line) of developing cell of the toner of " Japan " is compared, and the 3rd rib (being illustrated by dashed line) of developing cell that holds its destination and be the toner in " Europe " is formed on cap unit 3640 (being illustrated by solid line) more by in the position of lining.Like this, be installed to the attaching/detaching part 3050d that the destination is the printer 10 of Japan if the destination is European developing cell, then cap unit 3640 can't be closed.On the other hand, with being connected to the destination is that the 3rd cut-out (being illustrated by solid line) of cap unit 3640 of attaching/detaching part 3050d of the printer 10 of Japan is compared, and the 3rd cut-out (being illustrated by dashed line) of cap unit of attaching/detaching part 3050d that is connected to the destination and is the printer 10 in Europe is cut more by the lining.Like this, be installed to the attaching/detaching part 3050d that the destination is the printer 10 in Europe if the destination is European developing cell, then cap unit can be closed the attaching/detaching part.But, only the 3rd cut-out is cut to such an extent that more will to allow the destination by the lining be that the developing cell of Japan is installed to the attaching/detaching part 3050d that the destination is European printer 10.Consider this point, the destination is that the length of the 3rd rib (being illustrated by dashed line) on the direction that intersects with rotation axis CL of the developing cell in Europe forms to such an extent that be shorter than the 3rd rib 3583Y that the destination is a Japan.In addition, the width that to make the destination be the 3rd cut-out formed in the cap unit of printer in Europe on the direction that intersects with rotation axis CL is narrower than the length of the 3rd rib 3583Y that the destination is the developing cell of Japan.Like this, can prevent that the destination from being that Japanese developing cell by mistake is installed to the printer that the destination is Europe.
In addition, as shown in figure 33, first cut-out 3647 and second cut-out 3648 are arranged on the side of the rotation axis CL of cap unit 3640 rotations place, and the 3rd cut-out 3649 is arranged on the side of more close rotation axis CL.In other words, the distance X 1 between the coupling part 3644 and first cut-out 3647 or second cut-out 3648 ' be set as greater than the distance X 2 between coupling part 3644 and the 3rd cut-out 3649 '.
