As shown in Fig. 4, Fig. 5 (C), the coupling part 102 of coupling component 100 is tubular, has formed on circumferential wall from the center towards first engagement groove 104 and second engagement groove 106 of radiation direction.In addition, in the present embodiment, the center line of first engagement groove 104 and second engagement groove 106 is approximately 90 ° in the angle that core intersects.In addition, first dogleg section 204 of stirrer 200 described later is combined in first engagement groove 104, and second dogleg section 206 is combined in second engagement groove 106.
Also have, shown in Fig. 5 (A), in first engagement groove 104, formed a little bit smaller a little, the roughly rounded clamping part 120 of the diameter of axle than first dogleg section 204, then the diameter of axle than first dogleg section 204 is narrow for its inlet.Because first dogleg section 204 is combined in this clamping part 120, so stirrer 200 is not easy to pull out.
In addition, when being installed in toner cartridge 70 in the laser printer 10, coupling component 100 will be connected with the rotary driving force parts (not shown) that is arranged on laser printer 10 main bodys one side.And coupling component 100 is driven by this rotary driving force parts, rotates towards the S direction, and revolving force is passed to stirrer 200 in the toner cartridge main body 80.
In addition, coupling component 100 is used synthetic resin, and for example, POM (polyacetal resin) makes.
As shown in Figure 4, around the hole of being passed in the coupling part 102 of coupling component 100, pasted seal member 150.The sidewall sections 84 of this seal member 150 sealing toner cartridge main bodys 80 and the space between the coupling component 100, with the colour powder of xerographic printing that prevents toner cartridge main body 80 inside from sidewall sections 84 hole 98 (referring to Fig. 3) and the gap between the coupling component 100 leak into the outside.In addition, this seal member 150 is to use elastomeric material, and for example, neoprene is made.
As shown in Figure 3, stirrer 200 is arranged to roughly traverse the total length of whole toner cartridge main body 80, and shown in Fig. 3 (B), it is the wire rod made from the metal of circular cross section, for example, and the spiral helicine sweep 202 that stainless steel (SUS304WP) forms.In addition, an end of the spiral fashion sweep 202 of stirrer has formed towards the direction bending vertical with rotation (rotation center) M, first dogleg section 204 that combines with first engagement groove 104.In addition, it is crooked laterally about 90 ° also to have formed rotation (rotation center M) with respect to stirrer 200 at the front end of first dogleg section 204, is combined in second dogleg section 206 in second engagement groove 106.In addition, the front end of another end is abandoned free end.
As shown in Figure 4, stirrer 200 obtains revolving force from the coupling part 102 of coupling component 100, rotates to the S direction, and one side stirs the colour powder of xerographic printing in the toner cartridge main body 80, and one side is carried its direction to delivery outlet 90 (referring to Fig. 3 (A)).
In addition, shown in Fig. 3 (A), first dogleg section 204 of stirrer 200, be arranged to inside surface 84A near the sidewall sections 84 of toner cartridge main body 80, because spiral fashion sweep 202 begins to form from this first dogleg section 204, so spiral fashion sweep 202 can be arranged near the inside surface 84A of sidewall sections 84 of toner cartridge main body 80 always.Because spiral fashion sweep 202 is while the part that stirs the colour powder of xerographic printing of carrying toner cartridge main body 80 inside, so it can stir near the colour powder of xerographic printing the inside surface 84A of the sidewall sections 84 of toner cartridge main body 80 and carry.
In addition, as shown in Figure 6, when assembling toner cartridge 70, first dogleg section 204 of stirrer 200 is combined in first engagement groove 104 from the outer circumference surface insertion, and 206 insertions of second dogleg section are combined in second engagement groove 106.When inserting, the end face 200A of stirrer 200 does not contact with first engagement groove 104, second engagement groove 106.In addition, after the insertion, do not contact with the bottom surface portions 102A of coupling part 102 yet.
Because as previously mentioned, stirrer 200 is to make with the wire rod of metal manufacturing, when its end face 200A contacts with the coupling component 100 that is made of resin, when producing friction and scraping, can produce foreign matter (scraping powder), but, owing to the end face 200A of stirrer 200 does not contact with first engagement groove 104, second engagement groove 106, so when assembling toner cartridge 70, can not produce foreign matter (scraping powder).Therefore, also just can not be because of when assembling, producing foreign matter (scraping powder) because of scraping, can not allow this foreign matter (scraping powder) sneak in the colour powder of xerographic printing to be transported in the developing apparatus 20 (referring to Fig. 1) yet and go, the problems such as grade reduction of duplicating take place with colour powder of xerographic printing.
In addition, when (clamping part 120 fronts) midway that are inserted into first engagement groove 104, and after this going in the clamping part 120 and when applying strength in order to embed, at this moment the direction of Cha Ruing may not be the dead ahead, but it is crooked, will strongly be applied on the stirrer 200 and first engagement groove 104, the stirrer 200 and first engagement groove 104 may be out of shape.First dogleg section 204,, is its guiding, so can be inserted to right-on direction because second dogleg section 206 is also inserted second engagement groove 106 midway.Therefore, the stirrer 200 and first engagement groove 104 just can not be out of shape.
Also have, first dogleg section 204 of stirrer 200 and second dogleg section 206 are being inserted in the process of first engagement groove 104 and second engagement groove 106, even owing to error makes first dogleg section 204 of stirrer 200 and second dogleg section 206 run into seal member 150, because the end face 200A of stirrer 200 can not run into seal member 150, so seal member 150 can be not injured.Therefore,, can not make seal member 150 injured and colour powder of xerographic printing takes place leak yet, can insert again even insert error.
Below, the effect of toner cartridge of the present invention is described.
The coupling component 100 of toner cartridge 70 is connected with the rotary driving force parts (not shown) of main body one side that is arranged on laser printer 10, drives coupling component 100 by these rotary driving force parts and rotates.
Coupling component 100 passes to revolving force first dogleg section 204 of the stirrer 200 in first engagement groove 104 that is combined in coupling part 102.Accepted revolving force stirrer 200 afterwards and just rotated, with its spiral helicine sweep 202, Yi Bian stir colour powder of xerographic printing, Yi Bian carry colour powder of xerographic printing towards delivery outlet 90 (referring to Fig. 3).
In addition, as shown in Figure 4, when rotating owing to stirrer 200, the end face 200A of stirrer 200 is contact and connection parts 100 not, so even coupling component 100 rotations, the end face 200A of stirrer 200 can not rub with coupling component 100 yet.Therefore, can not produce because of scraping and cut the foreign matter that gets off.Like this, just can not produce bad phenomenon because of producing foreign matter.
In addition,,, also have so the combination of first dogleg section 204 can not rocked owing in first engagement groove 104, formed clamping part 120, owing to have second dogleg section 206 to be combined in second engagement groove 106, so rocking of H direction is also very little.Like this, stirrer 200 is fixed very firmly, and the rotation center of stirrer 200 can not be offset yet.
Also have, as shown in Figure 5, the center line of the groove of first engagement groove 104 and second engagement groove 106 is very big in the crossing formed angle of the core of coupling component 100, promptly, because coupling part 102 applies strength with a big chunk 102B on the circumferential wall to first dogleg section 204 (referring to Fig. 4), so the coupling part 102 of coupling component 100 can not be out of shape.
Therefore, can transmit revolving force to stirrer 200 with very high efficient, stirrer 200 can successfully rotate.In addition, stirrer 200 can not get loose yet.Therefore, can successfully carry out the stirring and the conveying of colour powder of xerographic printing.
In addition, in the present embodiment, the angle of bend of second dogleg section 206 (angle that the center line of the groove of first engagement groove 104 and second engagement groove 106 intersects on core) approximately is 90 °, but, test findings according to the applicant, if this angle is between 60 ° to 120 ° (referring to Fig. 5), can both firmly fix stirrer 200, in addition, the rotation center of stirrer 200 also is difficult to skew, therefore, can judge, it can transmit revolving force to stirrer 200 with very high efficient, and rotation is with very well.
In addition, the present invention is only limited to the foregoing description.
For example, in the above-described embodiments, first engagement groove 104 and second engagement groove 106 are to form from the center of the coupling part 102 of coupling component 100 along the radiation direction, but, be not limited only to this.For example, as shown in Figure 8, the center line of the groove of first engagement groove 704 and second engagement groove 706 is intersected beyond the center of the coupling part 702 of coupling component 700, and it is combined with first dogleg section 754 and second dogleg section 756 of stirrer 750.
In addition, for example, in the above-described embodiments, be on stirrer 200, to have formed first dogleg section 204 and second dogleg section 206, but, also be not limited only to this.For example, as shown in Figure 9, it also can be such structure, that is, on stirrer 850, do not form second dogleg section, only form first dogleg section 854, in addition, on the coupling part 802 of coupling component 800, only form first engagement groove 804, in second engagement groove 806 that first dogleg section 854 is combined in first engagement groove 804 and on the inwall of the tube of tubular coupling part 802, forms.
