Preferably will be with reference to the accompanying drawings, describe the toner-adding device that makes up according to the present invention in detail, and the preferred embodiment that is used for toner cartridge wherein.

Fig. 1-Fig. 3 represents the major part of the toner cartridge 2 of structure according to the present invention.Toner cartridge 2 has a container 4 and a mechanical switch 6 that is arranged on container 4 bottoms of leaving with toner.Mechanical switch 6 has the major component 8 that brute force is assembled to container 4 lower ends, becomes whole coupler, and the container valve element 10 that is arranged on major component 8 outsides.

Referring to Fig. 6-Figure 10, major component 8 can form by plastic material is Unitarily molded, and as ABS resin or PS resin, one of imaging of processing is cap completely.Major component 8 has first column part 12 and is formed on second column part 14 of first column part, 12 upper ends.Second cylinder 14 has the diameter bigger than first column part 12, so that form annular stepped part 16 between first column part 12 and second column part 14.In upper surface one side of step portion 16, and the inner radial of step portion 16 formation annulus 17, annulus 17 a little axially projects upwards in major component 8.Between the annulus 17 and second column part 14, form an annular recess, in annular recess, place a seal element (not shown).It is fan-shaped when observing vertically that the inner radial of first column part 12 forms a pair of diapire 18-that is 90 ° each other.

Two diapires are provided with respect to the central shaft of major component 8 position with symmetry, and continuous each other in the axle center.In the inside of first column part 12, and the zone except that corresponding diapire 18 radially forms a pair of open-work 20.Two open-works are provided with respect to the position with symmetry, the axle center of major component 8, and be each other 90 °-be fan-shaped when observing vertically.Each diapire 18 has level, the linear top portion of passing the axle center and arriving first column part, 12 radially inner sides, and is declined to become the dip plane from top portion to both sides.Along approaching V-shape perpendicular to the section of diapire 18 top portion directions, and the bottom surface of diapire 18 approaches X-shape, and all bottom surfaces are same planes with the basal surface of first column part 12 basically.

At the end portion of first column part, 12 outer surfaces, the

collar flange

22 and 24 that radially outward outstanding formation in axial direction separates.At the outer peripheral portion that is positioned at the flange 24 that axially makes progress, form outwards axially outstanding engagement in rotation part 26 and locking mesh part 28.Engagement in rotation part 26 (formation engaging-piece) and locking mesh part 28 are placed in respect to symmetrical position, major component 8 axle center.Remove outside the position that forms engagement in rotation part 26 and locking mesh part 28, flange 22 is identical with the diameter of flange 24.The length that engagement in rotation part 26 is given prominence to from flange 24 is greater than the length of locking mesh part 28.Form a groove 29 in a side of locking mesh part 28 along the circumferencial direction of flange 24, flange 24 is not in this groove.

At the inner circumferential surface of second column part 14, along the circumferential direction form the engagement concave surface 14a of four equidistant from distance.Each engagement concave surface 14a is a rectangle when observing from the axle center.At the end portion of the plastic containers 4 of leaving with toner, form a discharge gate (not shown).On the outer circumference surface of this discharge gate, form engagement convex surface with respect to engagement concave surface 14a.By engagement convex surface brute force separately is installed among the corresponding engagement concave surface 14a, container 4 intactly can be fixed on the major component 8.When container 4 was fixed on the major component 8, the discharge gate lower end of container 4 contacted with seal element, leaked to prevent toner.

On the outer circumference surface of second column part 14, form pair of meshing concave surface (side is recessed) 14b.Two engagement concave surface 14b press the symmetric position arrangement with respect to the axle center of major component 8, and are formed up to along the circumferencial direction extension, have constant axial width and constant axial depth in predetermined angular range.This angle is 90 ° or bigger.

With reference to figure 11-Figure 13.Locking member 30 is removable to be installed in flange 24 upper surfaces and between annular stepped part 16 lower surfaces on first column part, 12 outer circumference surfaces.Locking member 30 can by elastic plastic material such as ABS resin or the PS resin is Unitarily molded forms, and it has the body part 31 that comprises the annular plate element, and the annular plate element has predetermined width and preset thickness, also has two ends.Body part 31 can be thought the element of narrow relatively a, thin ribbon shaped, is round basically when observing vertically, and shape resembles a spiral when radially observing, and its two ends are separated from each other.The internal diameter of body part 31 annulus set and the external diameter of first column part 12 nearly equal.By the opposite end is in axial direction moved, locking member 30 is very easy to the conglobate form of elastic deformation, and its opposite end faces with each other basically along circumferencial direction.In case remove added power of enforcement, locking member 30 returns to original spiral-shaped.When locking member 30 becomes circle owing to elastic deformation, provide certain interval between an one end and the other end, and at one end form lock part 32.Lock part 32 has the lock flange part 34 that extends radially outwardly and locking claw type part 36, and this part is axially extended from lock flange part 34 and away from the other end of locking member 30.

When in axial direction observing, lock flange part 34 approaches rectangle.Locking claw type part 36 is peripheral edge portions of lock flange part 34 (along the end parts of peripheral direction away from locking member 30 other ends), and is stretched over lock flange part 34 from the body part 31 of locking member 30.The peripheral width of locking claw type part 36 is less than the peripheral width of lock flange part 34, and it axially outwards gives prominence to the outstanding length of the length of body part 31 less than lock flange part 34 simultaneously.Body part 31 width of locking member 30 are less than the spacing between flange 24 upper surfaces and annular stepped part 16 lower surfaces.The width of the other end of formation lock flange 34 is less than the width of body part 31 1 ends in the body part 31.It is intended that between the upper surface of flange 24 and annular stepped part 16 certain interval is provided, and lock flange part 34 can be moved axially between latched position and locking off-position, and the locking off-position will continue to describe in the back.

The locking member 30 of this structure basically with nervous state of contact be fixed on the outer circumference surface of first column part 12, between the lower surface of the upper surface of flange 24 and annular stepped part 16 (playing flange basically), what utilized is its elasticity.Gu Ding locking member 30 like this, force in the axially spaced-apart of its relative two ends between flange 24 upper surfaces and annular stepped part 16 lower surfaces to move, make locking member 30 be out of shape with the elasticity of shape of ring, its relative two ends face with each other with the direction of circumference basically.Locking claw type part 36 is connected mutually with the groove 29 of flange 24 (limiting the position of locking).This is that therefore, its relative two ends attempt to separate along the claw type direction under the effect of elastic restoring force because locking member 30 is former itself to have spiral-shapedly.On the outer circumference surface of first column part 12, loop concave is determined by the upper surface of flange 24 and the lower surface of annular stepped part 16, and be we can say that locking member 30 is fixed on this loop concave.With regard to the fixedly locked element 30 of this mode, annular stepped part 16 has the effect that can compare with flange 24 basically, that is, make locking member 30 in axial direction resemble above-mentioned the effect of elastic deformation, given a kind of axle spring power thus.Therefore we can say that loop concave is to be determined by the outer circumference surface of first column part 12 and two flanges.Under this stationary state, the thickness of body part 31 should be set for not outstanding from the outer surface of flange 24; The size of the radial front end of locking claw type part 36 should be set for not outstanding from the radial front end of locking mesh part 28; And the size of the radial front end of lock flange part 34 should be set radially outward the certain length of outstanding locking mesh part 28 for.

Next, container valve element 10 will be described.With reference to figure 14-Figure 18, container valve element 10 can by plastic material such as ABS resin or the PS resin is Unitarily molded forms, and its global shape resembles a cap.Container valve element 10 has flat basically diapire 40, and diapire 40 has the circular periphery limit, and first column part 42 extends vertically upward from the circumferential edge of diapire 40, and second column part 44 is formed on the upper surface of first column part 42.Second column part 44 has the diameter bigger than first column part, so that form the annular stepped part 46 of level between first column part 42 and second column part 44.In diapire 40, form a pair of through hole 48.With respect to the axle center of container valve element 10, two through hole is arranged on the position of symmetry, and respectively be basically 90 ° one fan-shaped.At the upper surface of the diapire 40 that does not comprise through hole 48, a seal element (not shown) is set.

Near the circumferential edge part of diapire 40 lower surfaces, the locking release pin 50 that a pair of formation outstanding along the axle center locks release is set.With respect to the straight line that passes the axle center, two lockings discharge pin 50 and are in symmetric position.Near second column part, 44 lower ends, what formation one extended radially outwardly is the flange 52 of ring-type basically.Be positioned at a part of flange 52, form one and compare radially further outstanding extension 54 with other parts.In this extension 54, form a pilot hole 56, constitute and suppress spinner.

In second column part 44 and first column part 42, form first groove 60 and second groove 62.With respect to the axle center of container valve element 10, the position symmetry that first groove 60 and second groove 62 are arranged.All each extends to position near first column part, 42 lower ends since top axial of second column part 44 for groove 60 and groove 62, and rectangular basically when observing from the axle center.The periphery width of first groove 60 is greater than second groove 62.In first column part 42, form a pair of slit 64 and 66.With respect to the axle center of container valve element 10, slit 64 and 66 position symmetries, and along the circumferential direction extend respectively, and have constant axial width.Along the circumferential direction, the coupling of the lower end of an end of slit 64 and first groove 60, and the other end of slit 64 is arranged in from the about 90 ° circumferential position of an end (being the clockwise position of Figure 14).Along the circumferential direction, the coupling of the lower end of an end of slit 66 and second groove 62, and the other end of slit 66 is arranged in from the about 90 ° circumferential position of an end (being the clockwise position of Figure 14).

Along the axial direction of second column part 44, form other a pair of slit 67 near its lower end.With respect to the axle center of container valve element 10, two slits, 67 position symmetries, and along the circumferential direction in predetermined angular range, extend respectively.On the inner peripheral surface of second column part 44, and vertically on relative other groove 67, form engagement convex surface 68.Engagement convex surface 68 extends in predetermined angular range respectively, has constant axial width and the constant thickness that radially inwardly stretches out.This angular range is set narrowlyer than the angular range of corresponding other slit 67.

Compare with regard to the periphery width, be installed in first groove 60 of the lock flange part 34 of the locking member 30 on the major component 8 less than container valve element 10.With respect to first groove 60, lock flange part 34 is suitable for moving axially, but along the circumferential direction can not move basically, and this is to hinder mutually because of it and first groove 60.The radially anterior locations of lock flange part 34 surpasses the excircle part of first column part 42 of container valve element 10.Compare with regard to the periphery width, the engagement in rotation part 26 of major component 8 is less than second groove 62 of container valve element 10.Be formed on the

flange

22 and 24 on major component 8 first column parts 12, its diameter is less than the internal diameter of container valve element 10 first column parts 42.The outer circumference surface of major component 8 second column parts 14, its diameter in lower axial end slightly greater than the internal diameter of container valve element 10 second column parts 44, and in the axial direction the part of face slightly greater than the internal diameter of second column part 44.

The installation of major component 8 and container valve element 10 is carried out respectively in the following manner: main reference Fig. 1-Fig. 5.Locking member 30 is installed on the major component 8, first groove 60 of lock flange part 34 on the major component 8 and container valve element 10 is aimed at.And, the engagement in rotation part 26 of major component 8 and second groove 62 of container valve element 10 are connected.Keep these alignments, major component 8 and container valve element 10 are forced to move towards direction separately vertically.Two engagement convex surfaces 68 that are formed on container valve element 10 second column parts 44 inner peripheral surfaces are installed among the engagement concave surface 14b that is formed on accordingly on major component 8 second circumferential sections 14 outer circumference surfaces.As a result, container valve element 10 and major component 8 link together, so that can rotate relatively but can not move axially, and the inner peripheral surface brute force of container valve element 10 second column parts 44 is provided on the outer circumference surface of major component 8 second circumferential sections 14.Each open-work 20 of major component 8 is closed by corresponding diapire 40 in the container valve element 10.

The engagement in rotation part 26 of major component 8 and locking mesh part 28 are positioned the bottom of container valve element 10 corresponding

recesses

62 and 60, and are positioned at the circumferential ends of

respective slots

66 and 64 thus.Being installed in locking member 30 on the major component 8 is positioned in the annular spaces between container valve element 10 first column parts, 42 inner peripheral surfaces and major component 8 first column parts 12 outer circumference surfaces.Two opposite ends of the lock flange element 34 of locking member 30 along the circumferential direction, are positioned between the peripheral relative two ends of groove 60 of container valve element 10.Locking claw type part 36 axially is installed to downwards by thrust (elastic force) in the groove 29 of flange 24 of major component 8 (promptly being positioned at latched position), the former elasticity because of locking member 30 of outfit.Therefore, the locking mesh part 28 of major component 8 is to the mobile inhibition that is subjected to locking claw type part 36 and lock flange part 34 of slit 64 directions, and major component 8 and container valve element 10 both be fixed to the state of locking.Leave with the container 4 of toner, as previously mentioned, be installed in the axial top of major component 8.

In the toner cartridge 2 of assembling like this, each open-work 20 is closed by corresponding diapire 40 in the container valve element 10, and the relative rotation of major component 8 and container valve element 10 is suppressed securely by 30 of locking members.Like this, if produce any vibration or loading behavior except that replenishing toner, as in transporting the process of toner cartridge, the open-work of major component 8 can not opened, and undesirable toner is drained and also effectively prevented.So, the phenomenon that the toner contamination surrounding environment can not take place or waste toner.

When the lock flange part 34 of locking member 30 was stressed, lock flange part 34 was resisted the thrust that is produced by its elasticity and is axially upwards left the locking mesh part 28 of major component 8, thereby moves up along container valve element 10.Like this, locking claw type part 36 is upwards removed (moving to the locking off-position) from the groove 29 of major component 8 flanges 24.As a result, the state of locked element 30 lockings is released, and the locking member 28 of major component 8 becomes and can move along slit 64, and major component 8 also can begin relative rotation with container valve element 10.When these two parts rotated until about 90 ° relatively, the locking mesh part 28 of major component 8 relatively moved along slit 64, and engagement in rotation part 26 relatively moves along slit 66 simultaneously.Each open-work 20 on the major component 8 has been aimed at corresponding through hole 48 on the container valve element 10, so the toner in the container 4 can be discharged from toner cartridge by discharge gate, open-work 20 and the through hole 48 of container 4.That is to say that container valve element 10 can rotate with respect to major component 8 between off-position that open-work 20 is closed and the open position that open-work 20 is opened.

What Figure 27 one Figure 30 showed is to replenish a mouthful on-off element 76.Replenish mouthful on-off element 76 and can by plastic material such as ABS resin or the PS resin is Unitarily molded form, it comprises a horizontal-extending and has the circular wall part 112 that the diapire 110 and on circular periphery limit extends vertically upward from the circumferential edge of diapire 110.In diapire 110, form a pair of through hole 114.With respect to the axle center that replenishes mouthful on-off element 76, each through hole 114 is arranged in symmetric position, and respectively be 90 ° basically-be viewed as fan-shaped from axial direction.Formed each through hole should be reserved an arcuate zone part 116 (space) between the circumferential edge of the arch section of each through hole and diapire 110.In these each arcuate zone parts 116 of diapire 110, form arc groove 118.With respect to the straight line that passes the axle center, each groove 118 position symmetry, and the radius of groove 118 is slightly greater than the major diameter part of locking member 100.In diapire 110, form a pair of arcuate slot 120.Each slit 120 linearity end from respective through hole 114 in Figure 27 counterclockwise extends, and has predetermined width.One end 122 of slit 120 is positioned at along the circumferential direction from the about 90 ° position of the groove 118 of respective through hole 114.Between the circumferential edge of each slit 120 and diapire 110, also reserve arcuate zone part 116.The width of each slit 120 is slightly greater than the small diameter portion of locking member 100.The periphery radially outward of slit 120 is positioned on the contiguous circumferential face with axle center, and this contiguous circumferential face is essentially the common circle side face of each through hole 114 arch section.Place, axle center at diapire 110 forms a pin part 124 of going out vertically downward.

In circular wall part 112, form each extends and have the predetermined circle width vertically downward since the upper end first groove 126 and second groove 128.First groove 126 degree of depth in axial direction is greater than the degree of depth of second groove, and first groove 126 width along the circumferential direction is greater than the width of second groove 128 simultaneously.Near first groove 126 position that an end (left end among Figure 27) appears at and arc groove 118 1 ends (left end among Figure 27) are same along the circumferential direction, the other end (right-hand member among Figure 27) of first groove 126 is positioned near the symmetric position of second groove 128 with respect to the axle center simultaneously.Second groove 128 has constituted and has been engaged device.

Referring to Figure 21 and Figure 22 and Figure 39, that the additional mouthful on-off element 76 of this spline structure is removable and insert rotationally in the concave surface 82 of body 74 in the mounting seat 70.Under this installment state, the pin part 124 of replenishing mouthful on-off element 76 is installed in the open-work 92 of body 74 rotationally, but the large-diameter portion that is provided in corresponding locking member 100 is simultaneously divided on the outer circumference surface arc groove 118 quilt release properties of additional mouthful on-off element 76, and said locking member 100 projects upwards from the diapire 86 of concave surface 82.Divide the top of outer circumference surface by the large-diameter portion that groove 118 is provided in corresponding locking member 100, replenish mouthful on-off element 76 and be suppressed with respect to the rotation of concave surface 82, the result of this lock-out state replenishes a mouthful on-off element 76 to remain on its off-position.The toner of the diapire 86 of concave surface 82 replenishes mouthful 72 diapires 110 that replenished mouthful on-off element 76 and closes.Second groove 96 of second groove 128 of additional mouthful on-off element 76 and concave surface 82 is aimed at, an end (right-hand member among Figure 23) aligning of first groove 94 in the other end of first groove 126 and the concave surface 82 in the additional simultaneously mouthful on-off element 76.Just, open direction (clockwise direction of Figure 39) along what replenish mouthful on-off element 76, replenish mouthful upstream side (right-hand member among Figure 23) of on-off element 76 first grooves 126 and aim at along a upstream side of opening direction (right-hand member among Figure 27) of first groove 94 in the body 74.And, replenish mouthful other end (left end among Figure 27) in on-off element 76 first groove downstreams, at the other end of opening the direction downstream along body 74 first grooves 94 and the circumferential position between body 74 second grooves 96.In addition, the edge replenishes the lower end aligned of first groove 94 of mouthful lower end of on-off element 76 first grooves 126 axial directions and concave surface 82.As above describe, the position relation between the concave surface 82 of additional mouthful on-off element 76 and body 74 obtains limiting.Be positioned at the low slightly degree of upper surface with replenishing mouthful the top of on-off element 76 circular wall parts 112 than body 74 roofs 80.When replenishing mouthful on-off element 76 when off-position (toner replenish mouthful 72 positions of closing fully) turns to open position (toner replenishes mouthful 72 positions of opening fully), replenish mouthful other end in on-off element 76 first grooves 126 downstreams and be positioned at along opening the position that direction is no more than first groove, the 94 downstream other ends of body 74.

From above description, will be easy to clear to, to from the diapire 86 of concave surface 82, project upwards the locking member 100 of (being positioned at latched position), axial direction along the power of resisting spring element 102 pushes, and can discharge the linking state (be about to locking member 100 and take the locking off-position to from latched position) that replenishes mouthful on-off element 76 major diameters part and arc groove 118.As a result, replenish mouthful on-off element 76 and in rotational direction obtain discharging with respect to the lock-out state of concave surface 82, thereby, replenish a mouthful on-off element 76 and can allow to rotate with respect to concave surface 82.At this moment, only there is the small diameter portion of locking member 100 to be in from replenishing mouthful position that on-off element 76 diapires 110 project upwards.Avoided additional mouthful of on-off element 76 mutual obstruction in rotational direction by replenishing mouthful on-off element 76 slits 120 (seeing Figure 40).In other words, because slit 120 holds the small diameter portion of corresponding locking pin element 100 when rotating, therefore allow to replenish mouthful on-off element 76 and turn to open position along opening direction from off-position.

Referring to Figure 31-Figure 35, receive base 78 and can by plastic material such as ABS resin or the PS resin is Unitarily molded form, it has when from observation near rectangle and horizontally extending installing plate 130 and the plate-like concave surface 132 that extends vertically downward from installing plate 130.Concave surface 132 has column part 134 and is positioned at column part 134 lower ends and the diapire 136 of substantial horizontal extension.In diapire 136, form a pair of through hole 138.Through hole 138 with respect to the axle center of concave surface 132 with the symmetric position arrangement, and be separately 90 ° basically-in axial direction be viewed as fan-shaped.At the upper surface of diapire 136 and in the circumferential edge of through hole 138, form the low degree part 139 that a upper surface is parallel to diapire 136 upper surfaces.The seal element (not shown) is installed on low degree part 139.In diapire 136, also form a pair of open-work 140.Open-work 140 approaches the circumferential edge of concave surface 132, and is arranged to symmetric position with respect to the straight line that passes concave surface 132 axle center.The diameter of each open-work 140 greater than the small diameter portion of locking member 100, is installed in the open-work so that this small diameter portion can move slightly.

The upper end of column part 134 should be outstanding vertically upward from the upper surface of installing plate 130 slightly.At the upper surface of installing plate 130, form a collar flange 142.Collar flange 142 should be arranged to the whole circumference of column part 134 outstanding upper ends is surrounded with constant interval.The upper surface of collar flange 142 is higher than the upper surface of column part 134.Less than the internal diameter of the circular wall part 112 of replenishing mouthful on-off element 76, the internal diameter of collar flange 142 is slightly greater than circular wall part 112 external diameters simultaneously slightly for the external diameter of column part 134.

In column part 134, form first groove 144 and second groove, 146, the first grooves 144 and second groove 146 shaft core position symmetry with respect to concave surface 132.First groove 144 extends axially to the upper surface of diapire 136 from the upper end of column part 134, and has predetermined circumferential width, and is rectangular basically when observing from the axle center.Second groove 146 extends axially near the middle body from the axial direction of the upper end edge column part 134 of column part 134, and has predetermined circumferential width, and is rectangular basically when observing from the axle center.The circumferential width of first groove 144 is greater than the circumferential width of second groove.First groove 144 radially outward forms an engagement convex surface 148 along same direction extension.

Engagement convex surface 148 comprises the sidewall 148a that extends radially outwardly from the opposite end along the circumferencial direction of first groove 144, along sidewall 148a radial direction at arcwall 148b that extends between the outer end and the diapire 148c that between the lower end of sidewall 148a, extends.When observing from the axle center, engagement convex surface 148 is radially basically, and its circumferential width is slightly greater than first groove 144.Engagement convex surface 148 extends to the position on diapire 136 upper surfaces slightly from the lower surface of installing plate 130.The outer circumference surface (outer circumference surface of arcwall 148b) of engagement convex surface 148 is located substantially on the plane identical with collar flange 142 outer circumference surfaces.The inner peripheral surface (inner peripheral surface of arcwall 148b) of engagement convex surface 148 is located substantially on the plane identical with collar flange 142 inner peripheral surfaces.Each sidewall 148a of formed engagement convex surface 148 should be that part column part 134 extends radially outwardly to arcwall 148b and links to each other.Form first groove 144 and engagement convex surface 148 in such a way.On the inner peripheral surface 149 of the arcwall 148b that meshes convex surface 148, the projection 150 that formation one extends radially inwardly from inner peripheral surface.Projection 150 should form, in the central authorities of engagement convex surface 148 (arcwall 148b) circumferencial direction, radially from upper to the next.The upper end of projection 150 is lower than the upper end position of column part 134.

In column part 134, form first slit 152 and second slit 154.The position of first slit 152 and second slit 154 is symmetrical with respect to the axle center, and circumferentially extends with constant axle center width separately.Be coupled along an end of slit 152 circumferencial directions with along the center section of first groove, 144 axial directions, and its other end is arranged in from an end about 90 ° or more (the clockwise position of Figure 31 and Figure 35) on the big circumference position.Be coupled along an end of slit 154 circumferencial directions with along the center section of second groove, 146 axial directions, its other end is arranged in from an end about 90 ° or more (the clockwise position of Figure 31 and Figure 35) on the big circumference position simultaneously.Outer end radially, second groove, 146 upper parts is subjected to the qualification of collar flange 142 inner peripheral surfaces.Like this, the upper end of column part 134 outward radial on the position of second groove 146 extends, and links to each other with the inner peripheral surface of collar flange 142.

In installing plate 130 or on the plate, form four spiral parts 156, two pilot holes 158 and pilot pins 159 that constitute the rotation rejector are installed.Each install spiral part 156 all be by the metal screw element from the lower surface mandatory carriage of installing plate 130 to from installing plate 130 upwardly extending column parts.Pilot pin 159 mandatory carriages are to the embossed section that is formed on collar flange 142 circumferential edge outsides, and are configured to project upwards from the last transverse plane of collar flange 142.With a pilot hole 158 be formed in the installing plate 130, in lower surface one side of embossed section, and in the position coaxial with pilot pin 159, this pilot hole 158 does not show.

The reception base 78 of this structure is installed on the base 74 movably, and the mode of installation should be replenished a mouthful on-off element 76 from top covering, and installing plate 130 be positioned at roof 80 above.Mainly, receive the pilot hole 158 of base plate 78 and the pilot pin 98 and 99 of body 74 and be equipped with the position that the pilot pin decision is installed referring to Figure 19-Figure 23.The mounting hole 97 of spiral part 156 and body 74 is installed is aimed at, and installing plate 130 is connected on the roof 80 of body 74 by means of mild steel machine screw.The column part 134 that receives base 78 is inserted in the circular wall part 112 of replenishing mouthful on-off element 76, so that can rotate relatively.The engagement convex surface 148 that receives base 78 is connected in first groove 94 of base 74.There is the space upper end of first groove 126 that forms in the lower end of engagement convex surface 148 and the additional mouth on-off element 76 circular wall parts 112.Receive second groove 146 of base 78 and second groove 96 of base 74 and aim at, go back and replenish second groove 128 that forms in mouthful on-off element 76 circular wall parts 112 and aim at.The open-work 140 that receives base 78 is provided on the minor diameter of locking member 100, has certain space.Receive the through hole 138 of base 78 and the toner of base 74 and replenish mouthful 72 alignings, and intermediate space is subjected to the shielding of the diapire 110 of additional mouthful on-off element 76.The position relation that receives base 78, body 74 and replenish mouthful on-off element 76 has constituted mounting seat 70 as above-mentioned qualification.

As previously mentioned, (connections) mounting seat 70 on the set feeder hopper of developing apparatus (not shown) is installed, its toner replenishes mouthfuls 72 and is generally closed by replenishing a mouth on-off element 76.Like this, can prevent effectively that article from falling into feeder hopper, perhaps toner is polluted by exotic.To be applied to the feeder hopper type sliding and when being installed in the there with respect to the imaging body as the present invention, can prevent bar none that toner in the feeder hopper is because rotation of installation process or the like and replenish mouthfuls 72 to external leakage by toner.Therefore, the pollution of surrounding environment or the waste of toner have been prevented.As a result, degenerate or shortcoming that developing apparatus is damaged is prevented fully such as developing function, and guarantee to form gratifying image.

Explain below that from the toner cartridge 2 of aforementioned structure the toner by mounting seat 70 replenishes mouthfuls 72, toner is added to process in the feeder hopper (not shown).At first, in the following manner toner cartridge 2 is fixed on the mounting seat 70 and (is positioned at supplementary view): main reference Fig. 1-Fig. 3, Figure 19 and Figure 36-Figure 38 are inserted into container valve element 10 first column parts 42 of toner cartridge 2 in the column part 134 that receives base 78.The lower surface of container valve element 10 flanges 52 is positioned in the upper end that receives base 78 collar flanges 142.At this moment the pilot hole 56 that is provided with in the container valve element 10 is provided on the pilot pin 159 of mounting seat 70.And, the locking mesh part 28 of major component 8 and the lock flange part 34 that is installed in the locking member 30 on the major component 8 are inserted in first groove 144 of receiving unit 78, simultaneously the engagement in rotation part 26 of major component 8 are inserted in second groove that receives base 78 146.The locking of container valve element 10 discharges pin 50 and receives corresponding open-work 140 alignings of base 70 and locking member 100, and locking member 100 is axially promoted downwards, they is arrived lock the off-position.

In case the pilot hole 56 of container valve element 10 is equipped with on the pilot pin 159 of mounting seat 70, finish the location with respect to receiving base 78 of container valve element 10, and its rotation is suppressed.And, because the locking mesh part 28 of major component 8 and lock flange part 34 are inserted in first groove 144 that receives base 78, so lock flange part 34 touches in first groove 144 upper end of the projection 150 that is provided with, and axially upwards relatively move with the elastic force of resisting locking member 30 along first groove 60 of major component 8.As a result, locking claw type part 36 is removed (promptly being positioned at the locking off-position) from the groove 29 of major component 8 flanges 24, the lock-out state of locking member 30 is released.And the engagement in rotation part 26 of major component 8 is inserted in second groove 146 that receives base 78, so that the front end of engagement in rotation part 26 and second groove that replenishes mouthful on-off element 76 be connected, toner cartridge 2 is put on the supplementary view on the mounting seat 70.

When the container 4 of toner cartridge 2 and major component 8 rotate about 90 ° by predetermined direction (among Fig. 1 and Fig. 19 clockwise) then, major component 8 rotates with respect to container valve and 10 and has passed through identical angle.Because engagement in rotation part 26 and second groove 128 that replenishes mouthful on-off element 76 are connected, replenish mouthful on-off element 76 and also rotate together and passed through identical angle (from the position of Figure 39 to the position of Figure 40) with major component.The locking mesh part 28 of major component 8 rotates along first slit 152 that receives base 78, and engagement in rotation part 26 rotates along second slit 154.Two parts touch the end of

respective slots

152 and 154, and their rotation is restricted thus, so that the rotation of major component 8 stops.Major component 8 and replenish mouthful on-off element 76 and turn to off-position from open position, and be positioned at the there.So the toner of the open-work 20 of major component 8, the through hole 48 of container valve element 10, the through hole 114 that replenishes mouthful on-off element 76 and body 74 replenishes mouth 72 and all aims at, make the toner of leaving with in container 4 be discharged in the feeder hopper.

In order to provide toner to replenish from toner cartridge 2 to after the feeder hopper, remove toner cartridge 2 from mounting seat 70, the container 4 of toner cartridge 2 is rotated about 90 ° with major component 8 by above-mentioned opposite direction, make toner cartridge 2 can get back to supplementary view.Each toner replenishes mouthful additional mouthful on-off element 76 of 72 quilts and closes, and the open-work 20 of each major component 8 is closed by container valve element 10 simultaneously.First groove 144 of the locking mesh part 28 of major component 8 and reception base 78 is aimed at, and second groove 146 of engagement in rotation part 26 and reception base 78 is aimed at.So toner cartridge 2 is with respect to mounting seat 70, becomes on the direction and can axially move up removing.

Provide toner cartridge 2 is moved up slightly with respect to mounting seat 70, the locking claw type part of locking member 30 36 because its elasticity and and the groove 29 of major component 8 flanges 24 be connected, become locked state (being positioned latched position).The open-work 20 of major component 8 is locked with closed condition by container valve element 10 as a result.Because toner cartridge 2 moves up, the locking of container valve element 10 discharges pin 50 and locking member 100 upwards separates.So locking member 100 is promoted to latched position by the spring force of spring element 102, thereby the rotation that replenishes mouthful on-off element 76 is suppressed.So toner replenishes mouthful additional mouthful on-off element 76 of 72 quilts and locks with closed condition.Then, toner cartridge 2 is axially moved up from mounting seat 70, make toner cartridge 2 from mounting seat, to remove fully.Moving up of toner cartridge 2 can also provide the spring force of spring element 102 to finish.

Next, Figure 41-Figure 49 has shown another embodiment of the mounting seat of removable installation toner cartridge 2.Figure 41 and Figure 42 show mounting seat 200.Mounting seat 200 comprise one be installed on the developing apparatus (not shown) feeder hopper and have for replenish toner form toner replenish mouthfuls 72 body 204, removablely be installed in additional mouthful of on-off element 206 on the body 204, be installed in replenish mouthful on-off element 206 tops in case can with the joystick elements 207 and removable being installed on the body 204 of its unitary rotation so that replenish the reception base 208 that mouthful on-off element 206 comprises joystick elements 207 from last covering.The body 204 of formation mounting seat 200, additional mouth on-off element 206 and reception base 208 structurally have improvement partly than the body 74 that constitutes aforementioned mounting seat 70, additional mouth on-off element 76 and reception base 78 (with reference to figure 19-Figure 35).Therefore, following description will concentrate on structural difference.Basically with Figure 19-Figure 35 in each identical element of respective element of showing, in Figure 41-Figure 49, just no longer explained, and several numbers identical with Figure 19-Figure 35 of use are represented.
