The utility model relates to a kind of toner Cartridge, recording unit, handle box and shutter opening and closing device, it can prevent reliably that toner from overflowing, device low price of the present invention, each modular construction is simple, processing ease, and if semi-open state took place, then could return to buttoned-up status easily.

Background technology

Up to now, utilizing electronic photography to form in the imaging device of coloured image, with the image carrier surface of the laser radiation photoconductor drum by LSU (laser scan unit) control, sensitization band etc. forming electrostatic latent image, electrostatic latent image with the Huang (Y) of developer, pinkish red (M), blue or green (C) and deceive (B) toner development so that electrostatic latent image as seen.Be transferred to by transfer printing unit at the toner image that develops on the image-carrier on the defeated medium of note of recording paper etc. of transmission, and in fixation facility, utilize heat and pressure that the toner of toner image is melted and photographic fixing to recording medium.This process is carried out in order, thereby forms predetermined coloured image on recording medium.

By the way, can utilize multiple being used for that toner image is delivered in transferring system on the recording medium, often use the intermediate transfer system that utilizes the intermediate transfer body.In the intermediate transfer system, the intermediate transfer body is set between each Y, M, C and B photoconductor drum and the transfer roll, from the color toner of photoconductor drum etc. by a kind of color of static printing primary depositing on the surface of intermediate transfer body forming toner image, and this toner image is transferred on the recording medium by transfer apparatus.

This intermediate transfer body is divided into intermediate transfer banding pattern and rotation drum type roughly.In arbitrary type, in the rotation of intermediate transfer body, carry out and develop and transfer printing, but they are very different on apparatus-form.That is, as the intermediate transfer body of rotation drum type, around the four pairs of color toner boxes and handle box are arranged on, whole drum rotation; And as intermediate transfer belt, the fixing series connection of the four pairs of color toner boxes and handle box (linearity) is provided with, annular intermediate transfer belt rotation.Intermediate transfer belt can make the machine miniaturization, because the shared volume of rotating part is little in the imaging device space.

In the tandem type intermediate transfer belt, Y, M, C and B photoconductor drum are with this order setting, and each handle box comprises developer roll and charger in addition, are used for to corresponding photoconductor drum supplying toner, and this handle box is arranged near the corresponding photoconductor drum.Be used for being arranged on handle box top (at vertical direction) to the toner Cartridge of handle box supply color toner.

But the imaging device in the background technology has following point: when handle box and toner Cartridge are attached to imaging device or when imaging device was dismantled, if connect or the dismounting Halfway Stopping, shutter was not exclusively opened (semi-open).As compartmentalized box for holding assorted fruits and candies once more from beginning attached or can not be finally attached or dismounting, around probably toner may splash as compartmentalized box for holding assorted fruits and candies.In addition, toner may spill in other cases.

Therefore, make dirty in order to prevent from the imaging device of background technology to change toner hand or parts on every side, toner Cartridge must be carefully and is connected swimmingly or dismounting, and this work is pretty troublesome for the user who carries out this work once in a while.

So, a kind of toner Cartridge and handle box are proposed, even also can attached reliably above-mentioned box when the user is unfamiliar with this work, and can not made dirty by toner on every side (with reference to JP-A-2007-219417).

The liner of the bar that is fixed compression is arranged in the communication path of toner Cartridge and handle box, and handle box is provided with by what elastic component was made and presses member, is used for upwards pushing away handle box and pushing shutter with the location.

Also propose a kind of technology, wherein without the tandem type shutter, and provide the rotation shutter, this shutter is provided with the lock construction element made by elastic plate to prevent that toner can spill (with reference to JP-A-7-152239) when toner is changed.But the shutter of toner Cartridge (JP-A-7-152239) need be provided with the elastic plate of big elastic force so that the sealing load rising of toner.

As mentioned above, each toner Cartridge and the handle box described among the JP-A-2007-219417 all comprise the shutter that is used to open and close the toner passage, fixed bar is rotated and is pressed towards two links of toner Cartridge and handle box, and shutter and fixed bar can wholely move.

But,, need good liner and elastic component with big elastic force for the sealing load of toner in the shutter that raises.And, if shutter is in semi-open state for a certain reason, do not allow to change places from semi-open recovering state.

For the sealing load of the toner that raises, the shutter of the toner Cartridge of describing among the JP-A-7-152239 also needs to have the elastic plate of big elastic pressure.If this causes cost to increase and the sealing load rising may be difficult to open shutter pro rata with elastic pressure, this also is a problem.In addition, also need the intensity of intensifier inside, so complex structure, cause cost further to increase.

Toner Cartridge and handle box in the use background technology, when box connected or dismantles, if change failure, shutter stayed open and I'm afraid that toner might spill.If shutter is semi-open, the state before it can not easily return in the structure.Even now also not any situation can both prevent that toner from spilling and for some reason shutter keep semi-open also can returning to easily to close fully or the simple in structure easy-to-use box of open mode.

To the elastic arm 16 shown in Fig. 7 be discussed briefly.As in Figure 15, two elastic arms 16 are formed with from outside two the jut 16a (outer pawl) of the center line of elastic arm; At the full closing state of shutter, two recesses (slot part in the utility model) that jut 16a cooperates (entering) to form in guide portion 18 inside (two elastic arm 16 sides) by pushing force, and fixed slightly.But when opening and closing hook 14 by when centerline direction is pushed shutter 15 sides to, shutter 15 receives thrusts, and component affacts the shutter skew back face of recess, and this inclined-plane curves inwardly the end of two elastic arms 16.Two elastic arms 16 terminal crooked, thereby inside surface that can sliding guidance portion 18, and shutter 15 can be placed in the state of partially opening.

If shutter 15 is further promoted and slides, the lug boss 32 (seeing Figure 15) of the end of switching hook 14 is near being formed into the convex compression zone 17 (seeing Figure 15) of two elastic arm 16 central authorities and being adjacent to each other; At this moment, shutter 15 is in full-gear.Fig. 8 illustrates the only state of B toner Cartridge 3 slips, and Fig. 9 illustrates the only state of B handle box 2 slips.

Figure 11 illustrates shutter door 13 at the opening/closing skeleton view of state midway, and Figure 12 is the sectional view of length direction (glide direction) when cutting open when Y, M, C, the B every kind color toner box 3 of the imaging device among Figure 11 1 in being arranged on imaging device.In Figure 12, the axle (axle of the present utility model) of Reference numeral 36 expressions first embodiment, be used for floating and freely swing (by the unsteady operation of the degree of freedom (front and back, and swaying direction up and down) on the unsteady strong point side that opens and closes hook 14) so that open and close hook 14.For by the degree of freedom adjustment to carry out swinging operation, axle 36 is stored part and surrounds, this storage area comprises storage wall 36a and opening 36b, this storage wall 36a is used to form the space of preliminary dimension so that open and close hook 14 and float in the unsteady strong point side (rear end side) that opens and closes hook 14, and opening 36b is used for switchings hook 14 strong point sides insertion storage wall 36a (see Figure 21 (a) and (b)) that float.

Detailed structure is described in the back.Open and close hook 14 and be provided with two adjacent parts: the first adjacency section 35a and the second adjacency section 35b, and in the given spatial dimension around the axle 36, float.Therefore, only compare, only can avoid rigid motion in the rotation of shutter 15 side ends by axle 36 simple situations about supporting with opening and closing hook 14.Figure 13 is the skeleton view that the state that shutter door 13 opens fully is shown; Figure 14 is when the sectional view of the imaging device among Figure 13 1 when the length direction of Y, M, every kind of color toner box 3 of C, B is cut open.In Figure 10,14,21 (a), 21 (b), Figure 22 etc.,, in a width of cloth figure, a plurality of swing states are shown simultaneously in order to understand aforesaid action easily.

The opening and closing operations (operation of the opening and closing of the shutter 15 of shutter opening and closing device just) of the shutter 15 of toner Cartridge 3 and handle box 2 among the utility model first embodiment will be discussed below and insert between two shutters 15 detailed structure of switching hook 14 of opening the introducing hole (two intercommunicating pores) of escape hole 15a and connection with the while synchronously.

Figure 15 (a) opens and closes the states that hook 14 and shutter 15 are isolated mutually before being illustrated between the elastic arm 16 that the lug boss 32 that opens and closes hook 14 ends inserts shutters 15; Figure 15 (b) illustrates its state in abutting connection with compression zone 17 (opening initial state) when lug boss 32 slides; Figure 15 (c) illustrates the state when shutter 15 is extruded in abutting connection with compression zone 17 along with lug boss 32, elastic arm 16 crooked and slips in targeting part 18, and shutter 15 is pushed (during opening); And Figure 15 (d) illustrates the state that the escape hole 15a of shutter 15 opens fully.It is integrally formed by resin/ABS etc. to open and close hook 14, owing to is formed by resin, opening and closing 14 on hook has slit 34, and this opens and closes hook can bending on the direction that slit 34 shrinks.Two elastic arms 16 are also formed by ABS resin etc., and curve inwardly in case be received in the force of compression of the direction that they face with each other.

Incidentally, outside the second jut 16a (pawl), two elastic arms 16 also are formed with a pair of first jut 16b (interior pawl), and this first jut forms towards the center line of elastic arm inside, as shown in figure 15.When the second jut 16a of outside (outer pawl) is coupled to the recess of guide portion 18 and is locked by the restoring force of two elastic arms 16, the space that forms by the end of interior pawl broaden (see Figure 15 (a) and (b)).Space in this moment between the pawl allows lug boss 32 to pass through.But, when two elastic arms 16 curve inwardly, the first jut 16b (interior pawl) closer to each other and maintenance and clamping lug boss 32.

For clamping lug boss 32, carry out above-mentioned (a) and (b), (c) and (d) during operation at the second jut 16a (outer pawl) and guiding piece 18, the first jut 16b (interior pawl) carries out the following operation relevant with lug boss 32 simultaneously.

To (b), lug boss 32 is by the space between the first jut 16b (interior pawl) from above-mentioned (a), and can not be sandwiched among the first jut 16b (interior pawl), but in abutting connection with compression zone 17.In case lug boss 32 is in abutting connection with compression zone 17 and get the hang of (c), on the inclined-plane of the recess of guiding piece 18, to creep and produce interior component owing to outer pawl, two elastic arms 16 begin to curve inwardly.At this state (c ') (not shown), lug boss 32 is clamped by compression zone 17 and a pair of first jut 16b (interior pawl).Therefore, two elastic arms 16 are drawing slip in the guide part 18 in clamping lug boss 32.At this moment, open and close hook 14 and shutter 15 and be integral by the lug boss 32 that is held and compression zone 17 and move and move to the fully open position, escape hole 15a is arranged on the state of partially opening simultaneously.They stop at fully open position (d) by the retainer (not shown) that is arranged on the toner Cartridge 3.

The operation of the lug boss 32 from above-mentioned (a) to (b) is common opening and closing operations, and the abnormal conditions of part or full open position may take place for a certain reason.But when unusual, in first embodiment, the failure safe structure that opens and closes hook 14 works.Even in abnormality, the failure safe structure also can make lug boss 32 can not be sandwiched in by the space between the interior pawl in the interior pawl, thereby can clamping lug boss 32.This theme is described in the back.

Therefore, when shutter door 13 is closed, usually switching hook 14 is pushed with the motion sequence of the shutter door 13 shown in Fig. 3,4,10,11 and 12, and by aforesaid operations (a) and (b), (c), (d) and operation (c '), escape hole 15a places full open position from buttoned-up status.On the contrary, if opening/close door 13 opens from state (d), along with at (c) following elastic arm 16 clamping lug bosses 32 of state (c '), lug boss 32 pulled into and opens and closes hook 14, elastic arm 16 before the precalculated position returns to shape and outwards broaden, the second jut 16a (outer pawl) is coupled to the recess of guiding piece 18 and places stationary state.At this moment, can allow lug boss 32 to be disengaged by the association of space between the first jut 16b (interior pawl) and the operation between shutter 15 and switching hook 14.Shutter 15 with open and close hook 14 and separate from integrality.At (d) state, shutter 15 is in buttoned-up status.

Therefore, can realize simultaneously that shutter 15 is moved to open position is withdrawn into off-position to close the operation of escape hole 15a with operation of opening escape hole 15a and the shutter 15 that will be retained in open position.Therefore, the state that shutter 15 is turned back to off-position can produce concurrently simultaneously with the extrusion operation of opening escape hole 15a.

In first embodiment, switching hook 14 is drawn out and shutter 15 is pulled, thereby does not need to overcome the power of elastic force, when shutter 15 is closed, toner discharging port can strengthen high leakproofness simultaneously by relatively little power opening/closing easily, and does not use elastic component such as spring.Therefore, the end of toner Cartridge 3 is not forced in the load of the pushing force of spring, thereby does not need to strengthen the intensity of end, does not need to consider the somewhat complex design of spring pressure and spring wire diameter yet, and structure can be simplified.

Shutter 15 can open and close reliably according to aforesaid operations usually.But, owing to can not affirm that machine does not produce mistake.Therefore, among first embodiment shutter 15 of shutter opening and closing device adopt the failure safe structures in case when fault takes place handling failure.It has can the secondary treating fault structure.

That is, if the escape hole 15a of shutter 15 is semi-open, the shutter opening and closing device that promotes switching hook 14, the first embodiment for some reason returns to shutter 15 easily and closes fully or full open position.For the failure safe structure is provided, the switching hook 14 of first embodiment is integrally formed with resin, and can make lug boss 32 close.In case accept from the inside power in the both sides of lug boss 32, the direction bending that two blade parts 31 can reduce at slit 34 overcomes inside power with elastic force simultaneously.

Figure 16 (a) illustrates half-open position, and wherein the escape hole 15a of shutter 15 opens under the state that switching hook 14 is not pushed; Figure 16 (b) illustrates lug boss 32 that opens and closes hook 14 and the state that is in the described right first jut 16b (interior pawl) adjacency in the state (a); And Figure 16 (c) illustrates blade part 31 pressurizeds that open and close hook 14 and on the inclined-plane of the switching hook side of interior pawl from the both sides bending further to make the gap turn narrow of lug boss 32, allow lug boss 32 by the space between the first jut 16b (interior pawl) (having the space that narrows down therebetween) at semi-open state, and the compression zone 17 of shutter 15 is promoted by lug boss 32.

In case lug boss 32 by the space between the first jut 16b (interior pawl) after, lug boss 32 is clamped by described first right jut 16b and compression zone 17, and makes at shutter 15 and open and close between the hook 14 and become possibility in operational association.Can realize on demand opening fully and close fully.Therefore, if shutter 15 owing to common impossible reason is opened, simply just can return to common state by closing shutter door 13 shutters 15 easily.

Therefore, in first embodiment, may occur in first between elastic arm 16, lug boss 32 and the compression zone 17 by crooked two elastic arms 16 and engage (clamping), and may occur in second between elastic arm 16, lug boss 32 and the compression zone 17 of the bending that has added two blade parts 31 fault-time and engage (clamping), and no matter the position of shutter 15 how, only simply by closing shutter door 13 and will opening and closing hook 14 and shutter 15 cooperations, the escape hole 15a of shutter 15 just can be adjusted to and close fully or full open position.Therefore, the shutter opening and closing device of first embodiment has the safeguard construction of handling any situation.

Figure 17 (a) is the skeleton view when the toner Cartridge of the utility model first embodiment full open position when the shutter side of bottom surface is seen; Figure 17 (b) is the skeleton view when the incomplete open and-shut mode when the shutter side of bottom surface is seen of the toner Cartridge in (a); And Figure 17 (c) is the skeleton view when the buttoned-up status when the shutter side of bottom surface is seen of the toner Cartridge in (a).Figure 17 (a) and (b) and (c) do not illustrate and open and close hook 14 show whole motion, the shape of guide portion 18, the state of two elastic arms 16, the open mode of each escape hole 15a and the shape of closed condition and compression zone 17 when shutter 15 when the bottom surface is seen.At Figure 17 (a) and (b) with (c), the hammerlock 37 of a part that is formed for shutter 15 is locked in the latch mechanism of complete off-position is arranged in the shutter opening and closing device part of toner Cartridge 2.The side of shutter 15 is fixed by the effect of hammerlock 37 as described later.

Figure 18 (a) is the skeleton view when the handle box of the utility model first embodiment full open position when the shutter side of end face is seen; Figure 18 (b) is the skeleton view when the incomplete open and-shut mode when the shutter side of end face is seen of the handle box in (a); And Figure 18 (c) is the skeleton view when the buttoned-up status when the shutter side of end face is seen of the toner Cartridge in (a).Figure 18 (a) and (b) and (c) do not illustrate and open and close hook 14 show whole motion, the shape of guide portion 18, the state of two elastic arms 16, the open mode of each escape hole 15a and the shape of closed condition and compression zone 17 of the shutter 15 the same with toner Cartridge as mentioned above 3.

Next, will whole shape and the operation that open and close hook 14 be discussed.Figure 19 (a) is the skeleton view that opens and closes hook among the utility model first embodiment, and Figure 19 (b) illustrates to open and close the skeleton view that hook inserts the state in the space of attachment portion of toner Cartridge and handle box; Figure 20 is when the skeleton view that opens and closes hook when bottom surface side is seen in the utility model first embodiment; Figure 21 (a) is the schematically showing of the switching hook operation of shutter opening and closing device part under the handle box connection status only in the utility model first embodiment, and Figure 21 (b) is the schematically showing of the switching hook operation of shutter opening and closing device part under the state that connects of toner Cartridge only in the utility model first embodiment; Figure 22 is the schematically showing of the operation of the switching hook of shutter opening and closing device part under handle box and the state that toner Cartridge all is connected in the utility model first embodiment.

Figure 19 (a) is the skeleton view that opens and closes hook 14, and Figure 19 (b) is the skeleton view that the state between the elastic arm 16 that opens and closes hook 14 insertion toner Cartridges 3 and handle box 2 (each shutter opening and closing device) is shown.At Figure 19 (a) with (b), the slit that Reference numeral 34 expression is above-mentioned, two blade parts 31 of the switching hook 14 that is formed from a resin in order to formation.Slit 34 can make two blade parts 31 curve inwardly.Along with the bending of blade part 31, lug boss 32 is close, can carry out the second above-mentioned joint, and lug boss 32 is by compression zone 17 and the described right first jut 16b (interior pawl) clamping.In order to realize bending, can convert power by the inclined-plane of the first jut 16b (interior pawl) swimmingly at compression direction thereby on the inserting side of lug boss 32, form taper surface.Taper surface inserts between the interior pawl, thereby reception is from the reacting force of the opposing squeeze pressure on the inclined-plane of interior pawl, the end of blade part 31 (lug boss 32) side is by the component bending of reacting force, the pitch smaller of lug boss 32, narrowed width, lug boss 32 is by the space between the first jut 16b (interior pawl).

Below, at Figure 19 (a) with (b), Reference numeral 35 expression float portion are used for making switching hook 14 to float around axle 36 at storage area when having some degree of freedom.Float portion 35 comprises the first adjacency section 35a and the second adjacency section 35b, and they are two that are perpendicular to one another, the shape of similar alphabetical L, and the first adjacency section 35a and the second adjacency section 35b are set in the face of axle 36.According to this structure, float portion 35 is swung in the storage area that holds this float portion 35, allow slightly to move up and down and slight seesawing.Open and close hook 14 and carry out swinging operation by the degree of freedom of the effect of float portion 35.Described degree of freedom allows to open and close hook 14 and is inserted between the shutter 15.

But,, still be difficult to be directed to reliably and swimmingly the space between the shutter 15 of toner Cartridge 3 and handle box 2 although float portion 35 has degree of freedom.Therefore, in the switching hook 14 of first embodiment, on the surface of handle box 2 sides, provide rib 33.Figure 20 is the skeleton view when the switching hook 14 of first embodiment when handle box 2 sides are seen, and shows rib 33.

Figure 21 (a) illustrates how to guide when only handle box 2 connects and opens and closes hook 14, and Figure 21 (b) illustrates how to guide when only toner Cartridge 3 connects and opens and closes hook 14.In addition, Figure 22 illustrates how to guide when two handle boxes 2 all are connected with toner Cartridge 3 and opens and closes hook 14.Slit 34 is formed on the central authorities that open and close hook 14, and two blade parts 31 are similar to letter U and extend, and slit 34 is arranged between them, and lug boss 32 is arranged on the end of blade part along slit 34.The height of rib 33 increases gradually to shutter 15 sides, and rib 33 is outstanding at the back side of blade part 31.From the end of the unsteady strong point that opens and closes hook 14, the first adjacency section 35a uprightly is provided with the direction opposite with rib 33.

If toner Cartridge 3 and handle box 2 all are connected in the imaging device 1, rib 33 slides owing on the guiding piece that acts on the upper surface that is arranged on handle box 2 of gravity, and the lug boss 32 of switching hook 14 inserts between the shutter 15 swimmingly.According to the structure and the storage wall 36a that open and close hook 14, if toner Cartridge 3 all is connected with handle box 2, related in operation with the closing movement of the shutter door 13 of storage area 1a, it is mobile along the outer surface (upper surface) of handle box 2 to open and close hook 14, on handle box 2, creep, lower surface (bottom surface) in abutting connection with toner Cartridge 3, turn to and insert the attachment portion (shutter opening and closing device) between toner Cartridge 3 and the handle box 2, and the lug boss 32 that opens and closes hook 14 enters the space between two elastic arms 16 of shutter 15.

That is, at the end that opens and closes hook 14 during, open and close the direction of insertion of hook 14 between toner Cartridge 3 and handle box 2 and turn to and insert in abutting connection with toner Cartridge 3 and handle box 2.Therefore, at the common state that uses this device, in other words, only when toner Cartridge 3 is connected with handle box 2, lug boss 32 enters the space between the elastic arm 16 of shutter 15, the shutter 15 of toner Cartridge 3 and handle box 2 is opened simultaneously, and the device that can avoid being caused by user's manual operation mistake leaks or pollution, and device can be used safely.

Because moving, the first adjacency section 35a of switching hook 14 and the second adjacency section 35b have simultaneously along axle 36 degree of freedom on every side, when the attachment portion (shutter opening and closing device) between end insertion toner Cartridge 3 that opens and closes hook 14 and the handle box 2, if the end of switching hook 14 is clipped between toner Cartridge 3 and the handle box 2 and the motion of lug boss 32 is restricted, the end that opens and closes the unsteady strong point side of hook 14 is not fixed to axle 36.Therefore, related in operation with the opening and closing operations of shutter door 13, the end that the motion that opens and closes hook 14 has degree of freedom and opens and closes hook 14 can insert swimmingly and open and close hook 14 simultaneously and rotate and move up and down.

Because opening 36b is arranged on the position lower than axle 36, when the shutter door 13 of storage area 1a was closed, the first adjacency section 35a that opens and closes hook 14 was around axle 36 and can guide lug boss 32 sides of shutter 15 downwards.According to this structure, at the open position of shutter door 13, the angle that opens and closes hook 14 can be adjusted according to being arranged on the opening 36b on the storage wall 36a and the arrangement of axle 36, thereby the end that opens and closes hook 14 can guide downwards with suitable angle by simple structure.

When shutter door 13 was closed and opens and closes the attachment portion of hook 14 insertion toner Cartridges 3 and handle box 2, the lower surface of the second adjacency section 35b was set to storage wall 36a contactless.Therefore, if open and close the attachment portion that hook 14 inserts toner Cartridge 3 and handle box 2, the motion that is inserted into the end (lug boss 32 sides) of attachment portion is adjusted, but the end of the strong point side of floating moves freely and can break away from; Insert attachment portion to finishing this insertion from opening and closing hook 14, be adjusted if insert the motion of the end of attachment portion, shutter door 13 side freedom, and related in operation with the opening and closing operations of shutter door 13, open and close hook 14 and insert attachment portion swimmingly.

But, if only handle box 2 connects, be directed into the motion of shutter door 13 direct of travel of the lug boss 32 of the related and switching hook 14 that moves in operation and open and close the direction of hook 14 (lug boss 32) from the disengaging of shutter 15 sides, and on handle box 2 from lower one to creeping to higher direction, thereby can prevent that the lug boss 32 that opens and closes hook 14 from inserting flexible arms 16.Because shutter 15 pressurizeds and escape hole 15a can not open.

If only toner Cartridge 3 is connected to imaging device 1, there is not handle box 2 below the toner Cartridge 3, if shutter door 13 is closed so, the lug boss 32 that opens and closes hook 14 does not dangle and does not insert flexible arm 16.In this case, can not open owing to shutter 15 pressurized escape hole 15a yet.In brief, only when toner Cartridge 3 all is connected with handle box 2 shutter 15 just can place open mode.

Related in operation with the motion of shutter door 13, the traffic direction that opens and closes the lug boss 32 of hook 14 is directed into and opens and closes the direction that hook 14 (lug boss 32) inserts the attachment portion of toner Cartridge 3 and handle box 2, thereby close the simple motion of shutter door 13 by utilization, the user can be reliably and easily will be opened and closed hook 14 insertion attachment portions, and does not need to carry out opening and closing the manual working that hook 14 inserts the trouble of connecting portions.

On the contrary, when the user opens shutter door 13 simply, open and close hook 14 and pull out the lug boss 32 that is clamped by two flexible arms 16 and compression zone 17, clamping has the flexible arm 16 of lug boss 32 to slide on guide portion 18, and escape hole 15a is closed gradually.When the second jut 16a (outer pawl) outwards broadens in the precalculated position of guide portion 18 and be coupled to recess on the guide portion 18 (seeing Figure 15), lug boss 32 separates with flexible arm 16 and is in buttoned-up status, opens and closes hook 14 and separates with shutter 15.

Next, will the structure that the escape hole 15a that only carries out shutter 15 in the precalculated position opens and closes operation be discussed.Figure 23 (a) is the enlarged side view of handle box connected major part after toner Cartridge in first embodiment of the present utility model, Figure 23 (b) is the handle box connected skeleton view after toner Cartridge in (a), Figure 24 (a) is the enlarged perspective of handle box connected major part after toner Cartridge in first embodiment of the present utility model, and Figure 24 (b) is the handle box connected side view after toner Cartridge in (a).

Figure 25 (a) is the enlarged side view of major part when toner Cartridge connects after the treating agent box in the utility model first embodiment; Figure 25 (b) is the skeleton view of toner Cartridge when connecting after the treating agent box; Figure 26 (a) is the enlarged perspective of major part when toner Cartridge connects after handle box in the utility model first embodiment; Figure 26 (b) is the side view of toner Cartridge when connecting after handle box; Figure 27 (a) is the enlarged side view of major part, is illustrated in the latch-release state of the shutter of toner Cartridge among the utility model first embodiment and Figure 27 (b) and is the skeleton view of the latch-release state of the shutter that the toner Cartridge in (a) is shown; Figure 28 (a) is the enlarged perspective that is illustrated in the major part of the latch-release state of the shutter of toner Cartridge among the utility model first embodiment, and Figure 28 (b) is the side view of latch-release state that the shutter of toner Cartridge is shown; Figure 29 (a) is the enlarged perspective of major part that locking that the shutter of toner Cartridge is shown was disengaged and carried out to open mode the state of transition, and Figure 29 (b) illustrates the enlarged side view of major part that locking to the shutter of toner Cartridge was disengaged and carried out to open mode the state of transition.

Shown in Figure 23-29, in the handle box 2 and toner Cartridge 3 of first embodiment, be used for adding from the hammerlock 37 of shutter 15 and stretch out towards the pushing force that keeps guiding piece 38 sides, when toner Cartridge 3 and handle box 2 move to the precalculated position, the lock-out state of shutter 15 is disengaged, and escape hole 15a opens.Under the state that in toner Cartridge 3 and handle box 2 at least one pulled out from imaging device 1, shutter 15 is arranged on closed condition.

The shape of hammerlock 37 is similar to leaf spring and forms heeling condition, and it can add downward pushing force.Retainer 37b is arranged on hammerlock 37 ends, and is arranged near the retainer 37b by the 37a of servo-actuated portion that keeps guiding piece 38 guiding.But when retainer 37b turned back to the position of fixing shutter 15 (end of the escape hole 15a of cover plate), hammerlock 37 was arranged on closed condition with the shutter 15 of toner Cartridge 3 and handle box 2.Therefore, when toner Cartridge 3 and handle box 2 were pulled out and taken off, toner can not spill.

Keep guiding piece 38 to be provided with smooth guide surface that the moving direction with shutter 15 extends in parallel and roughly shape such as trapezoidal smooth cam surface (protuberance of the present utility model), shown in Figure 23 to 28.When being pushed to by described effect at it, the 37a of servo-actuated portion of the end that is arranged on hammerlock 37 moves under the state that keeps on the guiding piece 38 and when arriving the pre-position, retainer 37b (insurance division of the present utility model) is fixed on the end that keeps guiding piece 38.Therefore, the position of closing toner discharging port 15a is adjusted in the position of shutter 15.On the other hand, when shutter 15 when pulled, the 37a of servo-actuated portion climbs on the cam surface and along tabular surface and moves from the end (closing the position of escape hole 15a) that keeps guiding piece 38, so shutter 15 moves with the direction that escape hole 15a opens.

Therefore, when toner Cartridge 3 is pushed so that toner Cartridge 3 is attached to imaging device 1, the 37a of servo-actuated portion climbs on the cam surface from the smooth guide surface that keeps guiding piece 38, retainer 37b promotes to overcome the pushing force of hammerlock 37 by action of cam, the stationary state of hammerlock 37 is removed, and the lock-out state (closed condition of escape hole) of shutter 15 motions is removed.When user side is seen, the user can only simply realize these sequences of operation by closing shutter door 13.Therefore, open and close hook 14 and insert between the flexible arm 16, therefore lug boss 32 makes flexible arm 16 bendings in abutting connection with compression zone 17, and flexible arm 16 slides on guide portion 18, and shutter 15 is pushed, and escape hole 15a can be set to full open position.

Hammerlock 37 keeps guiding pieces 38 towards keeping guiding piece 38 to push, and in connection status, cam surface can overcome the pushing force of hammerlock 37 and push back retainer 37b, no matter handle box 2 is to insert before toner Cartridge 3 or behind toner Cartridge.Therefore, shutter 15 can move to the position that escape hole 15a opens, and is irrelevant with the insertion sequence of toner Cartridge 3 and handle box 2.

The 37a of servo-actuated portion climbs on the cam surface and along cam surface from the end that keeps guiding piece 38 and moves, and correspondingly shutter 15 moves to open position.Therefore, retainer 37b overcomes the pushing force of hammerlock 37 along keeping guiding piece 38 to move, unrelaxing thereby the latch-release state can stably keep, and shutter 15 extruding are arranged on lip-deep cover plate and can utilize the pushing force of hammerlock 37 that high toner sealing load is provided simply.

By keeping guiding piece 38 and toner Cartridge 3, handle box 2 to insert the operation parallel work-flow, the locking of shutter 15 is disengaged.Therefore, only shutter 15 is arranged on removable state when toner Cartridge 3 is connected fully with handle box 2, be not connected to fully under the situation of handle box 2 at toner Cartridge 3, can not carry out the transition to the operation that two shutters 15 is arranged on synchronously open mode, can prevent that toner from spilling from toner Cartridge 3.

In order to realize this operation, keep the length of the cam surface of guiding piece 38 form with shutter 15 from the position of closing escape hole 15a (off-position) the corresponding distance of displacement to the position of opening escape hole 15a (open position).Therefore, roughly shape such as trapezoidal cam surface keep up and push away the state of retainer 37b, be set to open position (shutter is opened fully) up to shutter 15 from closed condition, thereby shutter 15 can be stablized the open position that moves to shutter 15 reliably under high toner sealing load, and the retainer 37b that has been forced pushing force is returned, move to the position of opening escape hole 15a up to shutter 15.The shutter 15 of toner Cartridge 3 and handle box 2 can be arranged on open mode synchronously.

When end at the cam surface that keeps guiding piece 38, retainer 37b adjusts shutter 15 when closing the position of escape hole 15a (end), the pushing force of hammerlock 37 is always forced at and is kept guiding piece 38 sides and keep guiding piece 38 not move or be offset from adjusting the position, adjusts the position thereby keep guiding piece 38 to be fixedly attached to reliably.Therefore, under the situation that adds any effects such as earthquake, does not move the position of shutter 15 yet.

In addition, when crawling on the cam surface and at tabular surface from the end that keeps guiding piece 38, moves retainer 37b, shutter 15 can move to the position of opening escape hole 15a, because this structure provides pushing force by hammerlock 37, shutter 15 is easily creeped on the cam surface of retainer 37b and maintenance guiding piece 38, and by adding with the rightabout power of pushing force and push back, fixing can easily the releasing.Each side in the both sides of the protuberance of cam surface all has the smooth curve inclined-plane, and the power on the direction that pushes away shutter 15 produces the power that overcomes pushing force easily gradually on the inclined-plane.

In order to remove the lock-out state of retainer 37b, employing is creeped the 37a of servo-actuated portion on cam surface structure, thereby by the retainer 37b that separates from the end of cam surface is creeped at smooth cam surface, shutter 15 is movably stablized disarm state and can be kept opening fully up to escape hole 15a simply.

Figure 23 (a) is the enlarged drawing of hammerlock 37 major parts when handle box 2 is connected, and Figure 23 (b) illustrates when handle box 2 connects hammerlock 37 and keeps mutual relationship between the guiding piece 38.Figure 24 (a) is the enlarged drawing of the major part of hammerlock 37 when handle box 2 connects; Figure 24 (b) illustrates when handle box 2 connects hammerlock 37 and keeps mutual relationship between the guiding piece 38.The state that handle box shown in it 2 connects.Handle box 2 connects after toner Cartridge 3.That is, these illustrated before the maintenance guiding piece 38 of handle box 2 promotes the 37a of servo-actuated portion of hammerlock 37, and retainer 37b appears at the state of cam surface end.Therefore, at this state, the shutter 15 of handle box 2 keeps closing.

Next, Figure 25 (a) is the enlarged drawing of the major part of hammerlock 37 when toner Cartridge 3 connects; And Figure 25 (b) illustrates when toner Cartridge 3 connects hammerlock 37 and keeps relation between the guiding piece 38.Figure 26 (a) is the enlarged drawing of the major part of hammerlock 37 when toner Cartridge 3 connects; Figure 26 (b) illustrates when toner Cartridge 3 connects hammerlock 37 and keeps relation between the guiding piece 38.The state that toner Cartridge shown in it 3 connects.Handle box 2 connected before toner Cartridge 3.The maintenance guiding piece 38 of handle box 2 does not promote the 37a of servo-actuated portion of hammerlock 37.Therefore, at this state, the shutter 15 of handle box 2 keeps closing in connection.

Figure 27 (a) is the enlarged drawing of the major part of hammerlock 37 when shutter is pushed under the attached completion status of toner Cartridge 3, Figure 27 (b) is the skeleton view that is illustrated in hammerlock 37 when shutter is pushed under the toner Cartridge 3 attached completion statuses and keeps mutual relationship between the guiding piece 38, Figure 28 (a) is the enlarged perspective of the major part of hammerlock 37 when shutter is pushed under the attached completion status of toner Cartridge 3, and Figure 28 (b) is the side view that is illustrated in hammerlock 37 when shutter is pushed under the attached completion status of toner Cartridge 3 and keeps relation between the guiding piece 38.Under this state, the 37a of servo-actuated portion promotes and is arranged on horizontality at cam portion, removes the stationary state of hammerlock 37.Therefore, closing of shutter 15 is disengaged, and if open and close hook 14 and be pushed, shutter 15 moves and can open escape hole 15a.

Figure 29 (a) is the enlarged drawing when hammerlock 37 major part when cam part is raised and is orientated in the horizontal direction, and Figure 29 (b) is a side view.Toner Cartridge 3 has the latch mechanism that is used for shutter 15 is fixed to the off-position of closing escape hole 15a.If toner Cartridge 3 is connected with handle box 2, latch mechanism is disengaged and makes shutter 15 to move to open position.Therefore, only when toner Cartridge 3 is connected with handle box 2, latch mechanism just is disengaged, thereby can prevent to spill device destruction or the pollution that is caused owing to user's manual operation mistake makes toner from toner Cartridge or handle box, and therefore device can be used safely.

As mentioned above, toner Cartridge according to first embodiment, recording unit, handle box and shutter opening and closing device, in order to open the toner connected entrance, open and close the compression zone of the lug boss extruding shutter of hook, thereby second jut of elastic arm is creeped and is moved along guiding piece from the slot part of guiding piece, related with moving in operation of second jut, first jut moves inward, and clamp lug boss from both sides, therefore the lug boss that opens and closes hook by the extrusion operation that opens and closes hook in abutting connection with compression zone, and it is related in operation with the extrusion operation that opens and closes hook, the lug boss that inserts the switching hook between the elastic arm by extrusion operation is clamped from both sides by first jut of the elastic arm that moves inward, thereby can be from slippage between the elastic arm.Therefore, be used for that shutter moved to the operation of the open position that described toner connected entrance is opened and operation that the shutter that is used for being retained in open position is withdrawn into the described off-position that described toner connected entrance is closed can be carried out simultaneously.Therefore, can reliably shutter be turned back to the state of off-position with the parallel simultaneously generation of the extrusion operation of opening the toner connected entrance.

In order to close the toner connected entrance, moving in operation of hook is related with opening and closing, first jut by two elastic arms is pulled out two elastic arms and shutter is moved from the lug boss of the switching hook of both sides clamping, thereby under the situation that lug boss is clamped from both sides by the jut of elastic arm, lug boss moves pulling out on the direction that opens and closes hook, thus the lug boss that opens and closes hook by reliably from sandwich up to pulling out the off-position that moves to shutter fully from opening and closing hook.Therefore, shutter can be withdrawn into the off-position with the front position reliably, and the lug boss of sandwich does not move during moving.

In order to close the toner connected entrance, when second jut of two elastic arms since they fall into guiding piece groove and when mobile, first jut is because the crooked of elastic arm outwards moves, and lug boss is from slippage between the elastic arm, and the clamp operation of switching hook is disengaged by the effect of elastic arm.Therefore, when shutter was pulled off-position, opening and closing hook can easily separate with shutter.

In addition,, adopt utilizing to open and close and be hooked in the structure that pushes back on the assigned direction or move shutter when retracting shutter, thereby the end of shutter is opened and closed the hook extruding with mobile shutter, and open and close hook and be drawn out to retract shutter for the opening/closing shutter.Therefore, do not need to overcome the power of elastic force, and when shutter was closed, when strengthening high leakproofness, toner discharging port can easily open and close by relatively little power.Because do not use the elastic component of spring etc., the end of toner Cartridge is not forced in the load of the pushing force of spring, thereby does not need to strengthen the intensity of end, does not need to consider the somewhat complex design of spring pressure and spring wire diameter, structure can be simplified.

In the utility model, the quantity of elastic arm is two, but is not limited to two, as long as shutter can be by clamping and shutter position can move to off-position or open position reliably.
