Embodiment
Referring to accompanying drawing Fig. 1, be that example illustrates and illustrated applied enforcement imaging device of the present invention with the duplicating machine.As shown in the figure, this duplicating machine comprises photoconduction (photoconductive) element or the image-carrier as drum 7.Drum 7 has OPC (organic photoconductor) or similar photoconductive layer, and rotates counterclockwise, as shown in Figure 1.Be arranged with charging roller or charging device 102, light writing unit or exposure device 103, developing cell or developing apparatus 1, image transfer roller or image transfer device 110, cleaning foil or cleaning device 105 around drum 7, and discharge lamp or electric discharge device 106.
Be applied with high-tension charging roller 102 negative polarity is filled on the surface of drum 7 equably.ADF (autofile feeder) 120 is installed in the top of printer main body 100.Scanner 130 comprises optical system 131 and CCD (charge-coupled image sensor) array or similar imageing sensor 132.When ADF120 delivered to the glass platen with file, imageing sensor 132 was read image information by optical system 131 by file.Light writing unit 103 scans the surface of drum 7 according to the view data of scanner 130 outputs with laser beam L, thereby forms sub-image on drum 7.Alternatively, view data can be from personal computer, facsimile equipment or similar unshowned image-data output device output.
Developing cell 1 stores the developer of toner and carrier formation, and has developing cylinder 5.Developer is deposited on the developing cylinder 5 with the form of magnetic brush.The developing cylinder 5 that rotates is transported to developing location in the face of drum 7 with developer.As a result, the toner that is included in the developer is transferred to drum 7 from developing cylinder 5, thereby and the development sub-image produce corresponding toner image.The drum 7 that rotates is transported to toner image on the nip or image transfer position that drum 7 and image transfer roller 110 be in contact with one another.
Paper box 109 is positioned at printer main body 100 bottoms, and is loading a stacker or recording medium P.The paper bowl 109a that gets that rotates is transported to registration roller to 107 with the paper P at top from paper box 109.Registration roller makes a short pause paper P to 107, and the forward position of the toner image that forms on the forward position of paper P and drum 7 drives this paper P when the image transfer position is joined then.
Before the forward position of paper P entered image transfer printing nip, the bias voltage that is used for the image transfer printing was applied to image transfer roller 110.Bias voltage makes roller 110 be charged to opposite polarity polarity with toner image, thereby in order to form electric field at nip.So under the effect of electric field and nip pressure, toner is transferred on the paper P from drum 7.
The spray point (not shown) is positioned at the downstream of above-mentioned nip on the paper throughput direction, and makes the paper discharge so that page is easy to break away from drum 7.Spray point is subjected to bias voltage or ground connection.The paper P that breaks away from from drum 7 is transported in the fixing device 108 that comprises warm-up mill 108a and pressure roll 108b.Warm-up mill 108a and pressure roll 108b that well heater is housed press mutually.The paper P that warm-up mill 108a and pressure roll 108b extruding is transferred, thus by heat and pressure with toner image on page P.
After the image transfer printing, cleaning foil 105 is removed the toner that remains on the drum 7.The toner conveyance device (not shown) turns back in the developing cell 1 toner of removing from drum 7, and is used further to develop.Discharge lamp 106 shines the whole surface of the drum 7 that was cleaned by cleaning foil 105, thereby eliminates the electric charge of staying on the drum 7.Use the method, make drum 7 perform the preparation of imaging next time.
To specifically describe drum 7 setting on every side in conjunction with Fig. 2.As shown in Figure 2, implement toner supplementary units of the present invention or install 200 and new toner is added in the developing cell 1 by the hole on the housing that is formed on developing cell 12.Below will describe toner supplementary units 200 in detail.First and second spirals 3 and 4 are positioned at housing, and the magnetic carrier particle that exists in the toner that will replenish and housing transmits additional toner when mixing to developing cylinder 5.
The magnet (not shown) is housed in the developing cylinder 5.Magnet makes developer carrier form magnetic brush on developing cylinder 5.By spiral 3 and 4 to developing cylinder 5 carry and the toner electrostatic precipitation of charging on carrier.The developing cylinder 5 that rotates will be carried to drum 7 attached to the toner on magnetic brush or the carrier.At this moment, doctor blade 6 is adjusted to preset thickness with toner.Then, toner deposits on the sub-image that forms on the drum 7, thereby forms foregoing toner image.
Toner sensor 8 be positioned at first spiral 3 below, the toner content of the developer that retains in the developing cell 1 with monitoring.Toner sensor 8 is set to for example respond the magnetic sensor of developer magnetic permeability, and the magnetic permeability of developer changes with the toner content of developer 1.When the magnetic permeability of developer was reduced to predetermined value, promptly when the toner content of developer descended, the signal of these states was represented in toner sensor 8 outputs.In view of the above, the controller (not shown) that comprises in the duplicating machine main body 100 sends to toner supplementary units 200 and replenishes order.After receiving order, toner supplementary units 200 is replenished toner by hole 2 to the housing of developing cell 1.It should be noted that toner sensor 8 also the perception toner exhaustion state and be close to the state of using up.
Explain toner supplementary units 200 below in conjunction with Fig. 2 to 4.As shown in the figure, toner supplementary units 200 comprises the housing 201 that is used to store the toner bottle 10 that fresh toner is housed.Housing 201 is generally by upper shell or cap 11, lower house or shell main body 12, and latching member or blocking device 13 compositions.Lower house 12 plays a part the shell main body of supporting toner bottle 10, and is formed with the opening 12b that is used to lay toner bottle 10.Upper shell 11 is installed on the lower house 12, to close opening 12b.The upper shell 11 that latching member 13 will be installed on the lower house 12 is locked on the lower house 12.
As shown in Figure 4, toner bottle 10 is provided with helicla flute 10a on its circumferential wall.When toner bottle 10 direction shown in the arrow in Fig. 2 was rotated, the toner that helicla flute 10a will be stored in the toner bottle 10 was carried to bottleneck 10b.As a result, toner is sent from toner bottle 10 through bottleneck 10b.Lid 14 removably is assembled on the bottleneck 10b, and in toner bottle 10 is placed in lower house 12.More specifically, lid 14 is placed on the lid bearing 15 that forms as one with lower house 12.
Lid bearing 15 is provided with toner outlet 15a.Toner guiding piece 16 is provided with porose 16a, and is installed on the part of the lid bearing 15 that is provided with toner outlet 15a.A plurality of mylars 17 are installed in and cover 14 toner endpiece, and along the circumferentially extending that covers 14.Slide plate 18 is installed on the toner guiding piece 16 selectively to open or close hole 16a.A unshowned spring is setovered slide plate 18 consistently so that slide plate 18 tends to block this hole 16a.More specifically, when toner supplementary units 200 was installed on the duplicating machine main body 100, slide plate 18 automatically moved to the position of not blocking hole 16a.
In operation, when the toner content of developer in the developing cell 1 tailed off as toner sensor 8 detects, controller sent to toner supplementary units 200 and replenishes order.In response, the unshowned kinematic train that is arranged in the duplicating machine main body 100 makes 10 bottles of rotations of toner.Kinematic train turns on the toner bottle 10 from the coupled structure transmission that is dynamically connected when being installed on the duplicating machine main body 100 in toner supplementary units 200.
When toner bottle 10 rotated, helicla flute 10a was transported to bottleneck 10b with the toner in the bottle 10.So the bottleneck 10b of toner through rotating with toner bottle 10 is discharged into and covers in the bearing 15.Be installed in the polyester film sheet 17 that covers on 14 and scoop up toner, the result is that toner imports in the toner guiding piece 16 through toner outlet 15a.Thereby, toner on the hole of toner guiding piece 16 16a and the above-mentioned housing that is formed on developing cell 1 hole 2 and add in the developing cell 1.
To make more specific description to the architectural feature of the housing 201 of illustrated embodiment below.As the clear demonstration of Fig. 7, upper shell 11 is provided with a plurality of hook 11a, and lower house 12 is provided with a plurality of flange 12a.Hook 11a is connected to upper shell 11 on the lower house 12 by slight snap fit and flange 12a engagement.Then, latching member 13 locks onto upper shell 11 on the lower house 12.
As shown in Figure 7, upper shell 11 and lower house 12 are respectively equipped with along housing 11 and 12 longitudinally extending rail sections 22 and 23.As shown in Figs. 5 to 7, latching member 13 is provided with parallel groove part 13a and 13b, make trench portions 13a and 13b housing 11 and 12 vertically on stretch.For housing 11 is locked onto on the housing 12, latching member 13 slides on housing 11 and 12 from the end opposite that toner replenishes end by the trench portions 13a that cooperates with rail sections 22 and 23 respectively and 13b.In this state, latching member 13 locks onto housing 11 on the housing 12 reliably.
In addition, as shown in figure 15, latching member 13 is provided with the groove 20 that stretches on the whole length of this part 13.When housing 201 was disassembled with recovery toner supplementary units 200, groove 20 allowed latching members 13 easily to open.So groove 20 helps easily separately upper shell 11 and lower house 12.Afterwards, new latching member 13 is used to once more upper shell 11 be locked onto on the lower house 12.In this mode, housing 201 can have mutually two housings 11 and 12 of locking reliably, and is easy to be separated from each other.
Fig. 6 shows that another kind helps to dismantle easily the ad hoc structure of the latching member 13 of housing 201.As shown in the figure, this latching member 13 is included in the wall 21 that stretches on the whole length of part 13.In dismounting, thin-walled 21 also allows latching member 13 to open easily thereon.
The condition precedent that groove 20 or thin-walled 21 are set be they or it when allowing latching member 13, can open easily in assembling in, prevent in the time of can in the transportation of toner supplementary units 200, be vibrated or impact that latching member 13 from unexpectedly opening.In order to satisfy this condition precedent, it is thick or thinner that the wall that is formed with the latching member 13 of groove 20 or thin-walled 21 should be preferably 1mm, more preferably is 0.7mm.Wall with groove 20 or thin-walled 21 preferably should be by hard frangible resin, and for example polystyrene constitutes.Under any circumstance, groove 20 or thin-walled 21 will shorten and reclaim the required time cycle of toner supplementary units 200.
Be damaged when the dismounting for fear of upper shell 11 and lower house 12, what housing 11 and 12 rail sections 22 and 23 separately preferably should be enough is firm.In addition, must distinguish the toner supplementary units 200 and new toner supplementary units 200 of recycling.In order to distinguish, each in housing 201 that the latching member 13 of particular color is preferably used for reclaiming and the new housing 201.This scheme is convenient to distinguish.
Fig. 8 represents to be in the toner supplementary units 200 of confined state.Dismantle the process of toner supplementary units 200 with the purpose that is illustrated as recycling with reference to figure 9 to 17.At first, as shown in Figure 9, pinch latching member 13, then pushing latching member 13 on the direction of the direction that slips into housing 201 perpendicular to latching member 13 with finger.As a result, latching member 13 fractures and the rail sections 23 of lower house 12 is unclamped from latching member 13.
Subsequently, the hook portion 11a of the upper shell 11 that slightly meshes with the flange 12a of lower house 12 by snap fit unclamps from flange 12a.So as shown in figure 10, upper shell 11 is removed from lower house 12, exposes the toner bottle of using 10 that is positioned on the lower house 12.As shown in figure 11, the latching member 13 that fractures further bends to remove from upper shell 11.
As shown in figure 12, the toner bottle of using 10 takes out from lower house 12 with lid 14.At this moment, being inserted in the drive system of duplicating machine main body 100 and the unitor 30 between the toner bottle 10 also is removed.Subsequently, as shown in figure 13, lid 14 takes off from toner bottle 10.Lid 14 and lower house 12 that cleaning is taken off from toner bottle 10 are to remove toner attached thereto (seeing Figure 14).
After above-mentioned dismounting, new toner bottle 10 is placed on the lower house 12.Then, carry out said process, to reuse toner supplementary units 200 with opposite order.
As shown in Figure 7, latching member 13 and lower house 12 preferably should be provided with claw 24 and hole 25 respectively.Latching member 13 usefulness are installed on the housing 201 with the claw 24 of hole 25 engagements.When being vibrated in transportation or impacting, this has prevented latching member 13 disengagement from housing 201 easily.Alternatively, latching member 13 is lockable on the upper shell 11.For example, shown in Figure 15 to 18, latching member 13 can be provided with claw 24 and flange 26, and upper shell 11 can be provided with hole 25 and claw 27.In this structure, claw 24 and hole 25 engagements, and flange 26 and claw 27 engagements.In this state, latching member 13 locks onto on the upper shell 11.
In the illustrated embodiment, light writing unit 103 is positioned at the toner supplementary units 200 times, as illustrated in fig. 1 and 2.As shown in figure 19, this writing unit 103 comprises the shutter 40 that can pivot around axle 41.Shutter 40 is located the light path that stops laser beam L usually, as shown in figure 19.Arm 42 also is installed on the axle 41, and is stretched in the light path, and toner supplementary units 200 is installed on the duplicating machine main body 100 along this light path, and pulls down from it.When toner supplementary units 200 was installed on the duplicating machine main body 100, arm 42 was in contact with it, and produced angular displacement because of the latching member 13 that is installed on the housing 201.Therefore, only when toner supplementary units 200 was installed on the duplicating machine main body 100, shutter 40 did not stop the light path of laser beam L.
As mentioned above, illustrated embodiment has various following listed unprecedented advantages.
(1) latching member of removing from housing 201 13 can not be reused.When the user plans to reuse the housing 201 that does not have latching member 13, can prevent that the duplicating machine main body from producing fault.This has also realized the method for depositing toner bottle 10 in housing 201 of prevention the problems referred to above.
(2) upper shell 11 and lower house 12 are made into separated components.This combines with the latching member 13 that is installed to upper shell 11, and housing 201 only could be reused when lower-cost upper shell 11 is changed by a new upper shell.In addition, latching member 13 itself separates with 12 with housing 11, and even is lower than upper shell 11 on cost.
(3) when latching member 13 slides on the housing 201, the trench portions 13a of latching member 13 and 13b lay the rail sections 22 and 23 of two housings 11 and 12.This guarantees housing 11 and 12 be connected.
(4) when latching member 13 with housing 11 and 12 mutually during locking, housing 11 and 12 mating part are hidden.This provides housing 201 good outward appearance, and prevents that the user from dismantling housing 201.
(5) latching member 13 is installed on the part away from the opening 10a of toner bottle 10 of housing 11 and 12.So, latching member 13, and then be that the workman of recycle bin is made dirty hardly.
(6) when the rail sections 22 of the trench portions 13a of latching member 13 and 13b and housing 11 and 12 and 23 engagements, claw 24 that cooperatively interacts and hole 25 have prevented that latching member 13 from sliding in the opposite direction.Therefore, when latching member 13 was vibrated or impacts in the process of transportation toner supplementary units 200, latching member 13 can be avoided throwing off from housing 201 easily.
(7) latching member promptly is installed on the housing 11 in the direction that housing 11 is pulled down from housing 12 on the direction of the direction that is installed to housing 12 perpendicular to housing 11.Therefore, both made flange 12a when the hook 11a of housing 11 and housing 12 for the ease of dismounting during by slighter snap-fit engagement, latching member 13 can make two housings 11 be connected reliably mutually with 12.
(8) supposition latching member 13 is subjected to slipping into external force on the direction (vertical direction in the illustrated embodiment) of direction (horizontal direction in the illustrated embodiment) of rail sections 22 and 23 perpendicular to trench portions 13a and 13b.Then latching member 13 loses it and makes housing 11 and 12 function of locking mutually.This has been avoided the user unscrupulously to reuse housing 201 reliably.
(9) particularly, the physical strength of latching member 13 is enough little, so that latching member 13 fragments into two parts at least between trench portions 13a and 13b when being subjected to above-mentioned external force.Thereby when pinching latching member 13 with finger and pushing, latching member 13 is easy to fracture.Particularly, latching member 13 is being as thin as 1mm or littler groove 20d place or the fracture of wall 21 places along trench portions 13a or 13b extension.This helps dismantling easily, reliably housing 201.
(10) but at least the breaking portion of latching member 13 constitute by polystyrene, and make latching member 13 be easier to the fracture.
(11) latching member 13 has the exclusive structure that can only be used for housing 201.Therefore, the user is difficult to replace latching member 13 with other parts that can commercial provide when planning to reuse housing 201.
(12) toner-adding device constitutes with lower house 12.Therefore can when replacing toner bottle 10, carry out the maintenance of toner-adding device.
(13) it is different with the color of the latching member of using 13 to be used to reuse the color of new latching member 13 of toner supplementary units 200.This allows to determine easily with eyes whether toner supplementary units 200 is new that this is convenient to safeguard.
(14) when toner supplementary units 200 when duplicating machine main body 100 is pulled down or is mounted thereto, the hole 16a of toner supplementary units 200 is automatically closed or opened to slide plate 18.Therefore, after toner supplementary units 200 is taken out from duplicating machine main body 100, prevented that toner from leaking through hole 16a.
(15) latching member 13 concerns mobile shutter 40 with what the attaching/detaching with toner supplementary units 200 engaged, and this shutter is used to block the light path of laser beam L.When not having toner supplementary units 200 in the duplicating machine main body 100, shutter 40 blocks above-mentioned light path.This has not prevented to be imaged on when having toner supplementary units 200 in the duplicating machine main body 100 and has carried out.
(16) toner bottle 10 has helicla flute 10a, and when the toner supplementary units 200 that has toner bottle 10 is installed on the duplicating machine main body 100, is copied machine main body 100 and rotates.Thereby toner supplementary units 200 does not need drive source, thereby simple in structure and in light weight.
