Powder jar and imaging device
Technical field
The present invention relates to a kind of powder jar, this powder jar is removably mounted on the powder such as ink powder that is consumed to replenish in the imaging process on the body of imaging device, and relates to a kind of imaging device that comprises this powder jar.
Background technology
For example the imaging device of hybrid machine has at least two functions in printer, duplicating machine or the facsimile recorder.When using imaging device, consumed toner; Thereby, replenish toner to developing cell constantly according to the consumption needs of toner.Typically use the toner container of toner Cartridge for example or toner jar to replenish toner.When the toner jar was sky, it was replaced by new toner jar.
The column toner jar of developing cell that is used for toner is added to traditional imaging device is for known, and for example it is disclosed in Japanese Patent Application No.2000-338758 (being hereinafter referred to as " first document ").
In first document, the toner jar is installed in the body (below be called " device body ") of imaging device as follows.
At first, the retainer that the user will install the toner supplementary units of body draws back, and takes out the slack tank on retainer then.Next, the user laterally is installed in new toner jar in the retainer.The user will have the rear portion of the retainer propelling toner supplementary units of new toner jar.Therefore, the recess that is arranged on the bottom of toner jar combines with the connecting portion at the place, rear portion of toner supplementary units.This position with the toner jar is installed in the toner supplementary units.
The inner peripheral surface of toner jar is provided with the spirality projection.Therefore, when driving connecting portion and rotation toner jar rotationally, the toner that is contained in the toner jar is discharged from opening.The toner of discharging from the toner jar adds in the developing cell.
Aforesaid toner jar cost is relatively low, and reason is, compares with for example having the toner jar of the transfer member of internal stirrers, has used less parts.In addition, above-mentioned toner jar is used for the purpose of recycle, because compare with the toner jar of loose shape, it has high-caliber physical strength.
Because the user need replace the toner jar,, and should prevent that toner from spreading out and the user's that makes dirty hand and clothes so the toner jar should be easy to replacement.In addition, if can not stably discharge the toner of stable quantity and add to the developing cell from the toner jar, it is inhomogeneous that toner concentration becomes.This causes decrease in image quality, for example image blurring or uneven color.Therefore, the toner of stabilizing amount need be discharged to the toner supplementary units from the toner jar and go.
Proposed and realized that various toner jars satisfy such needs.Known example be for example be disclosed in Japanese Patent Application No.2000-139031 (below be called " the cylindricality toner jar in second document ") with spiral toner delivery section.
Have outlet (opening) on an end of this toner jar, this outlet has the diameter less than the spirality tank body.This toner jar is installed in the device body so that the axis substantial horizontal of jar.In addition, the toner jar of the type is discharged toner by rotating from outlet.In addition, can be above device installation toner jar, and grip part (handle) is arranged on the toner jar.Therefore, the user can easily install the toner jar by using its finger.

Below explanation is according to the imaging device of first embodiment.Fig. 1 and Fig. 2 are used to illustrate the general structure of imaging device and the diagrammatic sketch of running.Fig. 1 is the diagrammatic sketch as the printer of imaging device, and Fig. 2 is the amplification diagrammatic sketch of the image-generating unit in the printer.
As shown in Figure 1,4 jar outer cover units 31 that are removably disposed in the top that is arranged in imaging device body (below be called " device body ") 100 respectively with the corresponding toner jar of yellow, reddish violet, blue-green and black 32Y, 32M, 32C and 32K.
Intermediate transfer unit 15 be arranged on jar outer cover unit 31 below.Align towards the intermediate transfer belt 8 of intermediate transfer unit 15 with yellow, reddish violet, blue-green and black corresponding imaging units 6Y, 6M, 6C and 6K respectively.
As shown in Figure 2, comprise photosensitive drums 1Y, and charhing unit 4Y, the developing cell 5Y, the cleaning unit 2Y that are provided with around photosensitive drums 1Y, remove static unit (not shown) etc. with yellow corresponding imaging units 6Y.Imaging processing (charge step, step of exposure, development step, transfer step, cleaning step) is finished on photosensitive drums 1Y, and yellow image is formed on the photosensitive drums 1Y.
Other three image-generating unit 6M, 6C have the structure identical with yellow corresponding imaging units 6Y basically with 6K, adopt the toner color image different with formation of different colours except each image-generating unit.Therefore, omitted explanation to other three image-generating unit 6M, 6C and 6K, and following only to describing with yellow corresponding imaging units 6Y.
As shown in Figure 2, photosensitive drums 1Y is rotatably driven along direction shown in the arrow R1 among Fig. 2 by the drive motor (not shown).The surface of photosensitive drums 1Y is in the charging (charge step) equably of the position of charhing unit 4Y quilt.
Subsequently, shine position on the photosensitive drums 1Y from exposing unit 7, by exposure/scanning the electrostatic latent image of yellow is formed on the surface of photosensitive drums 1Y (step of exposure) at laser beam L.
Subsequently, face the position of developing cell 5Y on the surface of photosensitive drums 1Y, the electrostatic latent image that develops, and form yellow toner image (development step).
Subsequently, face the position that the intermediate transfer belt 8 and first transfer bias are rolled 9Y on the surface of photosensitive drums 1Y, toner image is transferred to (first transfer step) on the intermediate transfer belt 8 from feeling bulging 1Y.In this step, a spot of toner is not transferred and remains on the photosensitive drums 1Y.
Subsequently, face the position of cleaning unit 2Y on the surface of photosensitive drums 1Y, blade 2a collects the toner (cleaning step) that remains on the photosensitive drums 1Y.
At last, face the position of removing static unit (not shown) on the surface of photosensitive drums 1Y, the current potential that remains on the photosensitive drums 1Y is removed.
Therefore, the imaging processing of carrying out on photosensitive drums 1Y finishes.
Other three image-generating unit 6M, 6C and 6K carry out with by the performed identical imaging processing of above-mentioned yellow image-generating unit 6Y.Specifically, in each of image-generating unit 6M, 6C and 6K, shine on the photosensitive drums based on the exposing unit 7 of laser beam L below being arranged on image-generating unit of image information.More particularly, exposing unit 7 with laser beam L reflection, is passed a plurality of optical elements with laser beam L then and shines on the photosensitive drums by rotating polygon mirror by light emitted laser beam L.
Subsequently, development step form toner image transfer printing on each photosensitive drums on intermediate transfer belt 8 with mutual superposition.The result is to form full-color toner image on intermediate transfer belt 8.
As shown in Figure 1, intermediate transfer unit 15 comprises 8, four first transfer bias cylinders of intermediate transfer belt 9Y, 9M, 9C and 9K, and the second transfer printing back-up roller 12 cleans back-up roller 13, tension roller 14, intermediate transfer cleaning unit 10 etc.Intermediate transfer belt 8 is by 12 to 14 tensioning and the supports of three cylinders.In addition, the rotation of the second transfer printing back-up roller 12 makes intermediate transfer belt 8 gyrate along the arrow indicated direction among Fig. 1.
Each of four first transfer bias cylinder 9Y, 9M, 9C and 9K intermediate transfer belt 8 with each clamping of photosensitive drums 1Y, 1M, 1C and 1K respectively.The result is that the opposite polarity transfer bias of polarity and toner is applied on each of the first transfer bias cylinder 9Y, 9M, 9C and 9K.
Intermediate transfer belt 8 rotates along the indicated direction of arrow, and passes through each first transfer nip of the first transfer bias cylinder 9Y, 9M, 9C and 9K continuously.The result is, each toner image transfer printing (first transfer printing) of respective color and overlapping onto on the intermediate transfer belt 8 on each photosensitive drums 1Y, 1M, 1C and 1K.
Subsequently, in the position of the intermediate transfer belt 8 that has overlapping toner image, in the middle of the second transfer printing back-up roller 12 and second transfer platen 19 are interposed in intermediate transfer belt 8, thereby form second transfer nip towards second transfer platen 19.In the full-color toner image that forms on the intermediate transfer belt 8 thereby be transferred on the transfer materials P, this transfer materials P for example is the transfer paper that is transported in second transfer nip.In this step, a spot of toner is not transferred to transfer materials P and goes up and remain on the intermediate transfer belt 8.
Subsequently, at intermediate transfer cleaning unit 10 places, the toner that remains on the intermediate transfer belt 8 is collected.
Therefore, the transfer process of carrying out on intermediate transfer belt 8 finishes.
The transfer materials P that is sent in second transfer nip transports out from the paper feed unit 26 of the bottom that is positioned at device body 100, passes paper supply roll 27 and a pair of registration cylinder 28.
Specifically, the transfer materials P of a plurality of for example transfer papers is stacked in the paper feed unit 26.When direction is rotatably driven shown in the arrow R2 (counterclockwise) of paper supply roll 27 in Fig. 1, top transfer materials P by paper feeding port 26a to a pair of registration cylinder 28 feedings.
This stops operating to registration cylinder 28 so that transfer materials P stops in this cylinder roll gap to registration cylinder 28.When the full-colour image of middle transfer belt 8 during near second transfer nip, 28 pairs on registration cylinder begins to rotate, thereby transfer materials P and full-color toner image synchronously are transported in second transfer nip.At this moment, the opposite polarity transfer bias of toner (voltage) of its polarity and intermediate transfer belt 8 lip-deep full-color toner image is applied on second transfer platen 19.The result is that intermediate transfer belt 8 lip-deep full-color toner image are transferred on the transfer materials P immediately.Therefore, required coloured image is transferred on the transfer materials P.
Change after second transfer nip prints on the transfer materials P at coloured image, transfer materials P is sent on the fixation unit 20.In fixation unit 20, photographic fixing cylinder and pressing roller are applied to heat and pressure on the transfer materials P, thus with the coloured image photographic fixing of institute's transfer printing on transfer materials P.
Subsequently, transfer materials P passes a pair of word bomb and goes out cylinder 29 and be transported to outside the device.Going out cylinder 29 by paired word bomb is ejected into a plurality of transfer materials P as output image outside the device and is stacked on continuously and covers on 30.
Therefore, the image of being carried out by described imaging device forms the processing end.
It more than is explanation to the imaging running that on transfer materials P, forms full-colour image.Yet, can finish imaging operation by only using one, two or three image-generating unit 6Y, 6M, 6C and 6K, thereby form monochrome image, 2 color images or 3 color images.
Next, describe structure and the running of the developing cell 5Y among the image-generating unit 6Y in detail with reference to figure 2.
Developing cell 5Y comprises the developing roller 51Y in the face of photosensitive drums 1Y, doctor blade 52Y in the face of developing roller 51Y, two transmission screw rod 55Y that are arranged on developer reservoir 53Y, 54Y inside, toner feed supplement unit 58Y by opening is communicated with developer reservoir 54Y detects the concentration detection sensor 56Y of toner concentration in the developer etc.Developing roller 51Y comprises the sleeve that is fixed on inner magnet and rotates around this magnet etc.The developer of two components comprises carrier and the toner that is stored among developer reservoir 53Y, the 53Y.

As shown in Figure 6, jar outer cover unit 31 has four jar housing department 31Y, 31M, 31C and 31K corresponding to four toner jar 32Y, 32M, 32C and 32K.Each of four jar housing department 31Y, 31M, 31C and 31K has the part 61 that combines with the joint portion of tank body, and the part (not shown) that is installed together with the installation portion of housing.
When toner jar 32Y is installed to device body 100 the jar outer cover unit 31 on the time, lid 30 is as shown in Figure 1 at first upwards opened to expose jar outer cover unit 31.
Subsequently, shown in Fig. 6 and 7, toner jar 32Y is installed in jar housing department 31Y and goes up (along the indicated direction of arrow).Toner jar 32Y is configured such that the joint portion 63Y on the bottom 62Y of tank body 33Y combines with jar part 61Y of housing department 31Y.Simultaneously, toner jar 32Y is arranged so that the part 39Y slip (with reference to figure 9 and Figure 10) of the straight wall of the installation portion 38Y that is provided with along jar housing department 31Y on the side of housing 34Y.Therefore, toner jar 32Y is installed between part 61Y and the part 39Y.This has limited toner jar 32Y to a certain extent and has shaken in a longitudinal direction.
Because joint portion 63Y is a spill, therefore can erect with bottom 62Y at bottom toner jar 32Y.This is convenient to toner is encased in process among the toner jar 32Y in factory, and is increased in user location, factory or sells the degree of freedom that the subsidiary company place stores toner jar stock.
In the present embodiment, be the part 61Y and the joint portion 63Y combination that is recessed circle of cylindricality, so that the bottom of toner jar 32Y can not be lifted from the wall portion of jar outer cover unit 31.Yet the shape of part 61Y and joint portion 63Y is not limited to these examples; For example, part 61Y and joint portion 63Y can form shown in Fig. 8 A, the 8B such.In Fig. 8 A, part 61Y has the taper that combines with spill joint portion 63Y.In Fig. 8 B, part 61Y comprises the dish 61Ya for disk or cruciform dish that combines with spill joint portion 63Y.In addition, joint portion 63Y can be spill and taper (not shown).
After toner jar 32Y was installed as shown in Figure 7, the user caught the handle 35Y of toner jar 32Y, and roll-shell 34Y.Therefore, the position of toner jar 32Y finally is installed among jar housing department 31Y.
Below explanation is used to install the motion of the housing 34Y of toner jar 32Y.
As shown in Figure 9, housing 34Y is mounted to and makes the straight wall of installation portion 38Y along the part 39Y of jar housing department 31Y slide (by the indicated direction of arrow E).Shown in Fig. 6 and 7, the joint portion 63Y of tank body 33Y combines with jar part 61Y of housing department 31Y.
When toner jar 32Y was installed on jar housing department 31Y, the straight wall of installation portion 38Y contacted with jar part 39Y of housing department 31Y, as shown in figure 10.Spring 44 is shifted the dividing plate 36Y of housing 34Y onto position (being locked in the position of the first block 45a) that toner outlet D is got clogged.
Handle 35Y is from moving along the direction shown in the arrow F in the position shown in Figure 10.Therefore, housing 34Y rotates along the indicated direction of arrow F.When the part of the wall of installation portion 38Y was hindered by part 39Y, housing 34Y stopped operating.
Toner outlet D rotates along with the rotation of housing 34Y, and finally is parked in bottom position (as shown in figure 11).In addition, the retainer 31a of jar housing department 31Y has hindered the rotation of dividing plate 36Y.Therefore, the edge of dividing plate 36Y presses the spring 44 that is at one end kept by the second block 45b, so that dividing plate 36Y opens toner outlet D.
When dividing plate 36Y opened toner outlet D when housing 34Y rotates, installation portion 38Y was installed on the part 39Y, so that the position of toner jar 32Y is installed among jar housing department 31Y.
Therefore, the user clearly feels mechanical click when toner jar 32Y is installed, thereby makes the user know that toner jar 32Y installs.This prevents that the user from correctly not installing toner jar 32Y.This prevents from correctly not replenish toner, and has prevented breaking of toner jar 32Y and jar parts of outer cover unit 31Y.
Especially, because joint portion 63Y combines with part 61Y at the 62Y place, bottom of toner jar 32Y, prevented that therefore bottom 62Y is lifted when tank body 33Y is rotated driving.When tank body 33Y is rotated driving, joint portion 63Y and part 61Y mutual friction mutually; Therefore, joint portion 63Y and part 61Y are preferably made by the material with low-friction coefficient.
When toner jar 32Y removed from jar housing department 31Y, the user carried out and the opposite process of process that toner jar 32Y is installed.Specifically, the user rotates the handle 35Y of toner jar 32Y along opposite direction (direction indicated with arrow among Figure 11 is opposite).Therefore, the installation portion 38Y of housing 34Y discharges from the part 39Y of jar housing department 31Y.Simultaneously, dividing plate 36Y relatively moves and toner is exported D and closes.The user holds handle 35Y when joint portion 63Y is discharged from part 61Y, and upwards pull out toner jar 32Y.

Other three toner jar 32M, 32C have and the identical structure of toner jar 32Y that contains Yellow toner with 32K, and different is its toner that contains different colours separately.The toner jar 32Y that contains Yellow toner only is described therefore; Yet present embodiment also is applicable to other three toner jar 32M, 32C and 32K.
In Figure 14, toner jar 32Y comprises the column tank body 133 as container body.Cylindrical shell 140 (cover) with lid function is arranged on the opening 35 of top end of tank body 133.Housing 140 rotates with respect to tank body 133.Tank body 133 comprises spiral projection (spiral transport part) 136, and when tank body 133 rotated, this projection was transmitted toner to opening 135.Housing 140 comprises cap `141, and this cap has toner outlet (the toner feed supplement opening) 144 that is arranged on the periphery bottom.Handle part 142 is fixed on the cap 141, and cap 141 is installed on the tank body 133.Housing 140 and tank body 133 be arranged on the clearance meshing of claw 143 and tank body 133 on the handle part 142, so that relative to each other can rotate.The place that seal 145 is arranged on tank body 133 and cap 141 combinations spills from this part to prevent toner.The handle part 142 of housing 140 comprises handle 146 and dividing plate 147.In addition, near being installed to place on the tank body 133, housing 140 is provided with jar gear 134.Jar gear 134 is the input gears as input part, and itself and tank body 133 integrally form.
When being installed to toner jar 32Y on the device body 100, at first upwards open to open wide a jar outer cover unit 31 at the lid shown in Fig. 1 30.As shown in Figure 6, after toner jar 32Y is installed on jar housing department 31Y, user's swing handle 146.This makes with handle 146 integrally formed housings 140 and rotates, and dividing plate 147 is moved on housing 140 along circumferential direction, thereby opens toner outlet (toner feed supplement opening) 144.Simultaneously, a housing 140 and a jar housing department 31Y interconnect and are fixed together.Such mechanism is not a main inventive point of the present invention; Therefore omitted detailed description thereof.The jar gear 134 that is installed in the toner jar 32Y among jar housing department 31Y is with the driven wheel (not shown) engagement of device body 100 and by its driving.
On the other hand, when toner jar 32Y removed from device body 100, the user is swing handle 146 in opposite direction.Therefore, discharge among 140 clumps of jar housing departments of housing 31Y.Simultaneously, dividing plate 147 is closed, thereby toner outlet (toner feed supplement opening) 144 closed.The user holds handle 146 when toner jar 32Y is separated from device body 100.Because toner jar 32Y can be installed on the device body 100 or from device body 100 by the top and separate, so understand and realize replacing easily the process of toner jar 32Y easily.In addition, because housing has handle 146, so toner 32Y can be easily mounted on jar outer cover unit 31 by roll-shell 140.When toner jar 32Y separated from installing body 100, even the handle 146 of roll-shell 140, dividing plate 147 can not opened yet.Therefore, when replacing toner jar 32Y,, prevented that the toner accident from spilling owing to keep dividing plate 147 to close.
As mentioned above, when attaching/detaching toner jar 32Y, 32M, 32C and 32K, hold handle 146.Therefore, owing to have only the end of toner jar 32Y to be held, so the center rotating shaft line of tank body 133 departs from the center rotating shaft line of housing 140.This has caused the problem that for example toner disperses and driving torque increases.
Therefore, in the present invention, on inner peripheral surface, be provided as the rib 148 that prevents member, with the tank body 133 that dwindles toner jar 32Y gap with housing 140 overlappings.Shown in Figure 14 and 15, each rib 148 is positioned at a side relative with respect to the central axis of housing 140 and handle 146.
As mentioned above, housing 140 has and is arranged on the side relative with handle 146.Therefore, even when the user holds handle 146 when rotating toner jar 32Y toner jar 32Y is installed in the device, and when only holding the end of toner jar 32Y, each rib 148 can prevent that also tank body 133 from unclamping from housing 140.This prevents to form the gap between housing 140 and tank body 133, thereby prevents that toner from disperseing.In addition, prevented that housing 140 from coming off or almost coming off from tank body 133.This has prevented the dispersion of toner and the increase of torque.In addition, when rotating tank body 133, the center rotating shaft line of each rib 148 restriction tank body 133 too far departs from preposition, so that do not form the gap between opening 135 and handle part 142.Therefore, the center rotating shaft line of tank body 133 can not depart from greatly holds the precalculated position, thereby has prevented the increase of torque.
In addition, owing to prevent that member from being rib 148, so prevent that member is less with the contact area of tank body 133 rotationally.This has reduced to contact the torque that is produced with tank body 133.
In addition, according to present embodiment, shown in Figure 15 to 17, three ribs 148 are parallel to the extension of central axis of housing 140.Rib 148a and handle 146 are relatively located, and rib 148b is positioned at the both sides of rib 148a.Rib 148a prevents that by himself weight tank body 133 from coming off or almost coming off from housing 140.When toner jar 32Y was installed in the device, owing to the load that handle 146 is applied, rib 148a and 148b prevented that tank body 133 from coming off or almost coming off from housing 140.This has prevented the dispersion of toner and the increase of torque.The quantity of rib 148 is not limited to three, and the rib 148 of any amount can be set.But when tank body 133 rotated, too many rib 148 may increase slip load; Therefore, housing preferably only has the rib 148 of minority.
Figure 18 is the skeleton view of housing 140 according to another embodiment of the present invention.In the present embodiment, be provided with as the hemispheric projection 149 that prevents member in the position relative with handle 146, it is similar to rib 148.Be arranged on the hemispherical projections 149 on the edge of housing 140 owing to prevent member, so prevent that the contact area of tank body 133 of member and rotation is quite little.This has reduced to contact with tank body 133 and the torque that produces.
Figure 19 illustrates another embodiment.Downward-sloping because of what gravity caused in order to prevent after tank body 133 is in being installed to device, another rib 148C or projection 149 preferably are arranged on the position corresponding to the bottom of housing 140.Owing to have this structure, when the user held handle 146, rib 148a and rib 148b had prevented that three positions tank body 133 is downward-sloping.In addition, when the toner jar was installed in the device and be driven in device, rib 148C prevented that toner tank body 133 is downward-sloping.
When use had the rib of differing heights, the optimum height of rib 148 was detected.Testing result is illustrated in the table 1.The rib that is used for this test satisfies following condition: shown in Figure 16 and 17, when the axis alignment of the central axis of tank body 133 and housing 140, tank body 133 is 2mm with the clearance delta L of housing 140 overlappings.Based on this condition, used four ribs, each rib has formed the gap beta of 0mm, 0.5mm, 1.0mm and 1.5mm between tank body 133 and housing 140.
[table 1]
Gap beta (mm) Toner disperses The turnability of toner jar
0 O (not disperseing) X (rib and the friction of toner jar and load increase)
0.5 O (not disperseing) O (good)
1 O (not disperseing) O (good)
1.5 X (dispersion) X (axis moves and the increase of loading)
As shown in table 1, the rib that forms 1mm and 0.5mm gap beta can not cause toner to disperse, and the turnability of toner jar is good.The rib that forms the 0mm gap can not cause toner to disperse, but because the big load that the friction of rib 148 and toner jar causes degenerates the turnability of container.In addition, the rib that forms the 1.5mm gap beta causes the turnability of toner dispersion and container to descend, and reason is to have moved central axis and increased rotating load.
The result shows that when clearance delta L was 2mm, the height of rib 148 was preferably about 1mm to 1.5mm.
Preferred embodiment of the present invention more than has been described.Yet, the invention is not restricted to these embodiment, but can carry out various changes.
For example, in a second embodiment, the toner jar is considered to the example of powder jar.Yet the powder jar is not limited to the toner jar; The powder jar can be the box that is used for storage of developer, and this developer is the potpourri of toner and carrier, or only is carrier.
As implied above, in the imaging device according to second embodiment, housing 140 comprises rib 148, and this rib 148 prevents from closely forming the gap between the handle part 142 of contact and the opening 135 mutually.In addition, when housing 140 was installed on the device body 100, rib 148 prevented to form the gap between handle part 142 and opening 135.Therefore, even hold handle 146 as the user when being installed to the toner jar in the device, and only hold an end of toner jar, rib 148 can prevent that also tank body 133 from unclamping from housing 140.This has prevented to form the gap between housing 140 and tank body 133, thereby has prevented the toner dispersion.In addition, in the precalculated position that housing 140 is installed in device body 100 after, roll-shell 140 so that its with the device body 100 the joint portion combine.In addition, when rotating tank body 133, it is too far away out of position that rib 148 has limited the center rotating shaft line of tank body 133, so that do not form the gap between opening 135 and handle part 142.Therefore, prevented that the center rotating shaft line of tank body 133 is too big out of position, thereby prevented the torque increase.
The invention is not restricted to these embodiment.Obviously, under the situation that does not break away from category of the present invention, can carry out various changes to the present invention.In addition, the quantity of parts, position and shape are not limited to these embodiment, and parts, position and the shape that can change over preferred amount are to realize the present invention.
