A-2. the structure of transmission member 20.
Fig. 2 is the side view of toner Cartridge 10.Describe the structure of transmission member 20 below in detail with reference to Fig. 1 and Fig. 2.
The enlarged side view of the sections in Fig. 3 presentation graphs 2 from the section A-A to the section B-B.Spiral component 23 is arranged to center on and extend along turning axle 21 spirality.As shown in Figure 3, spiral component 23 comprises high angle part 231 that axially is arranged alternately and the low angle part 232 along turning axle 21.Changeing around one of turning axle 21 in corresponding each sections of spiral component 23 at least one low angle part 232 is set with this spiral component.The number percent of the cumulative volume of the spiral component 23 that low angle part 232 is shared is littler than high angle part 231.For example, in the present embodiment low angle part 232 occupy spiral component cumulative volume 1% to 30%.The function of high angle part 231 and low angle part 232 is slightly different each other.That is to say that the major function that high angle part 231 is endowed is that developer feeding is axially being presented developer along turning axle 21 during to imaging device.On the other hand, the major function that is endowed of low angle part 232 is to present and the loose toner that is compacted along the sense of rotation of spiral component 23.
A-3. the structure of spiral component 23
Fig. 4 is the cut-open view of sections of expression from the section A-A to the section B-B, and the structure of the spiral component 23 of expression when developer feed direction upstream side is looked.With reference to Fig. 3 and Fig. 4 sections from the section A-A to the section B-B is described below.
As shown in Figure 4, spiral component 23 extends along the axial spirality of turning axle 21, draws the spiral camber line around turning axle 21.In above-mentioned sections, spiral component 23 is made of high angle part 231A, 231B and the low angle part 232 that is clipped between high angle part 231A, the 231B.For convenience of explanation, suppose that the volume of high angle part 231A and 231B is identical, this volume defines by the cumulative volume of a high angle part 231 is halved.The spiral extension direction of high angle part 231A and 231B is α 1 (embodiment of first angle) with respect to the angle of the axial c of turning axle 21, and wherein the spiral extension direction is the tangential direction that forms the edge (ridge) of the outer shape of each high angle part 231 at each high angle part 231 and the joint between the corresponding low angle part 232.The bearing of trend of low angle part 232 is α 2 with respect to the angle of the axial c of turning axle 21, and wherein this bearing of trend is the tangential direction at edge that forms the outer shape of low angle part 232 at each high angle part 231 and joint between the corresponding low angle part 232.As shown in Figure 3, angle [alpha] 2 is less than angle [alpha] 1.
The top ends of stirring plate 24A supports the end of high angle part 231A.The other end of high angle part 231 is connected to an end of low angle part 232.In addition, the other end of low angle part 232 is connected to the end of high angle part 231B.The other end of high angle part 231B is supported by the top ends of stirring plate 24B.As previously mentioned, high angle part 231A and 231B are the members with equal volume.Therefore low angle part 232 is positioned at high angle part 231A and is connected to center between the end that the end of stirring plate 24A and high angle part 231B be connected to stirring plate 24B.Two ends be connected respectively to high angle part 231A and 231B low angle part 232 be centered close to a position, along axially the looking of turning axle 21 time, becomes 90 to spend and locate with each center of stirring plate 24A and 24B at the center of this position low angle part 232 around rotation.That is to say that 23 bearing of trend becomes 90 to spend with the perpendicular line that extends to turning axle 21 from the center of low angle part 232 from turning axle 21 to spiral component to stir plate 24A and 24B.
Construct all identical a plurality of (for example being 11 in the embodiment of Fig. 2) sections and axially be connected to each other, be offset the phase differential of 180 degree around turning axle 21 each other along turning axle 21 with above-mentioned sections.Therefore, between two perpendicular line that extend respectively from the center of two adjacent low angle parts 232, keep 180 degree angles.
Because on the developer of action of gravity in being filled in vessel, so its lowermost position of developer in vessel more and more is compacted.As shown in Figure 4, when spiral component 23 when the direction shown in the arrow D is rotated, spiral component 23 lower right area in the drawings is subjected to reacting force Fu upwards owing to the inertial force of developer.Simultaneously, spiral component 23 zone, lower-left in the drawings is subjected to downward reacting force Fd.Specifically, low angle part 232 is used for loose developer when the sense of rotation along spiral component 23 transmits developer.Low angle part 232 is subjected to easily from the reacting force Fu of developer and the influence of Fd.Therefore, when spiral component 23 is in the following time of state that the line that wherein connects per two adjacent low angle parts 232 is level (wherein above-mentioned per two adjacent low angle parts 232 is those low angle parts that are provided with each other in 180 degree around turning axle 21), be delivered to the high angle part 231 that is clipped between per two adjacent low angle parts 232 by per two adjacent low angle parts 232 along the reacting force of opposite directions effect.Therefore, in this state, deform probably or break.Stir above-mentioned reacting force that plate 24A and 24B be used for being delivered to high angle part 231 (comprising 231A and 231B) and further scatter and be distributed to turning axle 21, thereby prevent distortion or break.
A-4. developer fill method
The method of filling toner Cartridge 10 with the developer of appropriate amount will be described below.
When filling toner Cartridge 10 with developer, low angle part 232 is as the directrix of learning developer level to be filled.More particularly, the posture of container 11 is remained under the axial horizontal state of the turning axle 21 of transmission member 20 wherein.Fill toner Cartridge 10 with a certain amount of developer, even make that any low angle part 232 of spiral component 23 all is embedded in the developer during the rotation of transmission member 20.In other words, the above-mentioned state of the axial level of turning axle 21 be exactly wherein developer reservoir be arranged so that turning axle 21 is parallel to the state on the plane vertical with gravity direction.Low angle part 232 is provided with 180 degree at interval around turning axle.Therefore, make any low angle part 232 be embedded in total measurement (volume) over half that developer level in the developer equals the vessel of toner Cartridge 10.Therefore, use the developer level over half of the total measurement (volume) of the vessel that occupies toner Cartridge 10 to fill toner Cartridge 10.
Perhaps, can fill developer and make that two adjacent low angle parts 232 all were embedded in the developer when line that remains on the center that wherein connects per two adjacent low angle parts 232 when spiral component 23 was horizontal state.Because low angle part 232 all has constant width and along the length-specific of the sense of rotation of spiral component 23, so can make amount that two adjacent low angle parts 232 all are embedded in (comprising width) developer in the developer greater than half of the total measurement (volume) of the vessel of toner Cartridge 10.Like this, low angle part 232 can contact developer more continually, and developer more effectively therefore can loosen.
Yet it is desirable to spiral component 23 does not have whole being embedded in the developer.In vessel, do not fill in the remaining free space of developer, can not produce reacting force owing to the motion of spiral component 23.Therefore, can be easily under the initial driving state loose developer.In this structure, spiral component 23 will be pushed on the developer in the free space, and developer is made developer spread along all directions by the gas-circulating such as air like this in free space.Therefore easily loose developer.In addition, do not produce reacting force free space have the load that helps reduce to impose on spiral component 23.
A-5. the operation of transmission member
As mentioned above, in case toner Cartridge 10 is filled with the developer of capacity, any low angle part 232 of spiral component 23 just is embedded in the developer.Fig. 5 is the side view of the state that rotatablely moves of expression transmission member 20.Fig. 5 A is illustrated in transmission member 20 and begins to rotate predrive state before.Fig. 5 B represents the and then initial driving state of transmission member 20 after the developer stationary state shown in Fig. 5 A begins to rotate.Fig. 5 C represents that transmission member 20 keeps the driven state of rotation special time.The zone of getting ready among Fig. 5 A to 5C all refers to developer.
Under the predrive state shown in Fig. 5 A, the developer that is filled in the toner Cartridge 10 keeps static.When transmission member 20 during from the rotation of this state, the low angle part 232 of spiral component 23 is along the inwall rotation of vessel, thereby any low angle part 232 all always contacts developer.By all parts of spiral component 23, make developer (sense of rotation and axial c) motion in two directions.Yet, each low angle part 232 with respect to the angle [alpha] 2 of the axial c of turning axle 21 less than the angle [alpha] 1 of each high angle part 231 with respect to the axial c of turning axle 21.Therefore, compare with high angle part 231, low angle part 232 more effectively transmits developer along sense of rotation than c vertically.
Then, under the initial driving state shown in Fig. 5 B, developer is not also fully loosened, but still in the compacting thick and fast of the bottom of vessel quilt.Therefore under this state, the power of resisting to the developer motion is acted on produces the reacting force bigger than other state.On the other hand, still there is the free space that is not filled with developer in the top at vessel under the initial driving state.In this free space, only there is gas such as air.Therefore, spiral component 23 from the regional movement that is filled with developer when not filling the free space of developer, for example when spiral component 23 moved upward above developer surperficial from downside along sense of rotation, spiral component 23 was subjected to less relatively reacting force.Thereby, when in each low angle part 232 under the initial driving state when come out in the interface, developer is loose especially easily.In addition, the stirring plate 24 that turning axle 21 is connected to spiral component 23 stirs developer, makes that developer is loosened more effectively.Thereby, under the initial driving state after and then transmission member 20 begins to rotate, the low angle part 232 loose developers that are compacted.According to rotatablely moving of transmission member 20, a spot of loose developer in toner Cartridge 10 developer and the interface zone between the free space above the developer in move up and down.

B-2. the structure of transmission member 1020.
Fig. 9 is the side view of toner Cartridge 1010.Describe the structure of transmission member 1020 below in detail with reference to Fig. 8 and Fig. 9.
The enlarged side view of the sections in Figure 10 presentation graphs 9 from the section A-A to the section B-B.Spiral component 1023 is arranged to center on and extend along turning axle 1021 spirality.As shown in figure 10, spiral component 1023 comprises first that axially is arranged alternately 1231 (embodiment of high angle part) and the second portion 1232 (embodiment of low angle part) along turning axle 1021.Though second portion 1232 limits especially with respect to the shared number percent of the cumulative volume of spiral component 1023, in the present embodiment second portion 1232 occupy spiral component 1023 cumulative volume about 1% to 30%.
B-3. the structure of spiral component
Figure 11 is the cut-open view of the sections from the section A-A to the section B-B in the presentation graphs 9, and expression is from the structure of the spiral component 1023 when the feed direction upstream side is looked.With reference to Figure 10 and 11 sections from the section A-A to the section B-B among Fig. 9 is described below.
As shown in figure 11, spiral component 1023 extends along the axial spirality of turning axle 1021, draws the spiral camber line around turning axle 1021.Spiral component 1023 is supported by being connected with turning axle 1021 with 1024B via back up pad 1024A.Turning axle 1021, spiral component 1023 and back up pad 1024A and 1024B are the rod components that all has specific thicknesses.Between these members, there is the gap.In above-mentioned sections, spiral component 1023 is made of the 1231A of first, 1231B and the second portion 1232 that is clipped between the 1231A of first, the 1231B.For convenience of explanation, suppose that the volume of 1231A of first and 1231B is identical, this volume is by the cumulative volume of a first 1231 being halved and being defined.The spiral extension direction of 1231A of first and 1231B is α 1 with respect to the angle of the axial c of turning axle 1021.The bearing of trend of second portion 1232 is α 2 with respect to the angle of the axial c of turning axle 1021.As shown in figure 10, angle [alpha] 2 is less than angle [alpha] 1.
Back up pad 1024A is arranged in the above-mentioned sections along the member of the substantially linear of the upstream side of feed direction, and extends along the direction perpendicular to turning axle 1021.Back up pad 1024B is arranged in the above-mentioned sections along the member of the substantially linear in the downstream of feed direction, and also extends along the direction perpendicular to turning axle 1021.When looking, between stirring plate 1024A axially adjacent one another are and 1024B, keep 180 degree angles, as shown in figure 11 along turning axle 1021 along the axial direction that is parallel to turning axle 1021.
The top ends of back up pad 1024A supports the end of the 1231A of first.The other end of the 1231A of first is connected to an end of second portion 1232.In addition, the other end of second portion 1232 is connected to the end of the 1231B of first.The other end of the 1231B of first is supported by the top ends of back up pad 1024B.As previously mentioned, 1231A of first and 1231B are the members with equal volume.Therefore second portion 1232 is positioned at the 1231A of first and is connected to center between the end of back up pad 1024A and the end that the 1231B of first is connected to back up pad 1024B.The center of second portion 1232 that two ends are connected respectively to 1231A of first and 1231B becomes 90 to spend and locate around rotation and each back up pad 1024A along axially the looking of turning axle 1021 time with 1024B.
Construct all identical a plurality of (for example among the embodiment in the drawings being 11) sections and axially be connected to each other, be offset the phase differential of 180 degree around turning axle 1021 each other along turning axle 1021 with above-mentioned sections.Like this, formed spiral component 1023.
B-4., the reason of second portion 1232 is set
Below the reason that second portion 1232 is set will be described.Transmission member 1020 has and will be converted into along the function of the axial linear movement of turning axle 1021 as rotatablely moving of rotation center with turning axle 1021.In order to carry out this function, transmission member 1020 is provided with spiral component 1023.To utilize xyz coordinate system explanation to be provided with the spiral component 1023 of second portion 1232 below and another spiral component 1230 of second portion 1232 will not be set, and will describe the difference between these spiral components.
Figure 12 is the stereographic map that expression is not provided with the spiral component 1230 of second portion 1232 on the xyz coordinate system.In Figure 12, suppose that spiral component 1023 and spiral component 1230 extend along the z direction of principal axis spirality of xyz coordinate system.For the purpose of simplifying the description, suppose that spiral component 1230 does not have thickness on the direction perpendicular to the z axle in the following description.Based on this hypothesis, spiral component 1230 is expressed as the hurricane band that is limited between curve f1 and the f2.The edge of spiral component 1230 is expressed as curve f1 and f2.Curve f1 is a limit near initial point, and curve f2 is another limit.Δ z keeps at a distance between z direction of principal axis upper curve f1 and f2.Symbol Δ z refers to spiral component 1230 along the axial thickness of z.θ refers to the angle that extends in x axle when being parallel to the axial direction of z and looking and the arbitrfary point from the spiral component 1230 between the perpendicular line of x axle.In addition, r refers to the distance between spiral component 1230 and the z axle.That is, r represents the screw diameter of spiral component 1230, and is arbitrary constant in this case.α refers to along the angle between the tangent line of the direction parallel with the perpendicular line that extends to the z axle from arbitrfary point arbitrfary point curve f1 on z axle and the curve f1 at spiral component 1230 when looking.That is, α refers to the axial angle of spiral component 1230 with respect to turning axle 1021, and is arbitrary constant.
Figure 13 is the amplification stereogram of the very little part of curve f1.As shown in the figure, if above-mentioned angle θ offset d θ, the arbitrfary point Q0 on the curve f1 is displaced to a Q1 so.Planar S comprises a Q0 and perpendicular to the z axle.On planar S, obtain some Q2 by putting Q1 rectangular projection.Thereby the track from a Q0 to a Q1 (camber line Q0Q1 hereinafter referred to as) rectangular projection is the track (camber line Q0Q2 hereinafter referred to as) from a Q0 to a Q2.At this moment, obtain the length of camber line Q0Q2 as having the length of the camber line of radius r and interior angle d θ, i.e. rd θ.At camber line Q0Q1 along the axial side-play amount of z (that is, the line segment length of tie point Q2 and Q1) when being dz, the relation of the equation (1) below angle [alpha], dz and d θ satisfy.
r·dθ/dz＝tan?α …(1)
Suppose that curve f1 o'clock gives z=0 in θ=0, to equation (1) integration.So, curve f1 is represented by following equation (2) on the xyz coordinate system.
x＝r?cos?θ
y＝r?sin?θ …(2)
z＝(r/tan?α)·θ
Curve f2 is represented by following equation (3) on the xyz coordinate system simultaneously.
x＝r?cos?θ
y＝r?sin?θ …(3)
z＝(r/tan?α)·θ+Δz
The forming method of resin material has two kinds.A kind of method is injection moulding, wherein is expelled under High Temperature High Pressure by the thermoplastic resin that will heat liquefaction and carries out moulding in the metal pattern.Another kind method is a casting, wherein rigidizer is mixed at normal temperatures in the resin of liquefaction, and the resin that will be mixed with this rigidizer pours in the metal pattern at normal temperatures and pressures.Thereby the resin that is mixed with rigidizer causes polyreaction, therefore finishes moulding.In any of these methods, need make fluent material in the set time, keep given shape by metal pattern, and shaped article need be separated with metal pattern.As mentioned above, constant between spiral component 1230 and the z axle apart from r.Therefore, be used for keeping the metal pattern of spiral component 1230 to have with the shape of z axle as the cylinder V0 at center from the inboard.Figure 14 A represents along the cross section of the cylinder V0 of xy plane cutting.Figure 14 B is the side view at the spiral component 1230 that forms around cylinder V0 when being parallel to the axial direction of z and looking.In Figure 14, suppose that planar S 0, S1, S2, S3 and S4 are perpendicular to the z axle.The curve f1 of spiral component 1230 is at θ=0 place and crossing perpendicular to the planar S 0 of z axle, and is crossing with the planar S 2 perpendicular to the z axle at θ=π place, and crossing with the planar S 4 perpendicular to the z axle at θ=2 π places.The curve f2 of spiral component 1230 is crossing with the planar S 1 perpendicular to the z axle at θ=0 place, and is crossing with the planar S 3 perpendicular to the z axle at θ=π place.
To consider below whether cylinder V0 is divided into cutting part by planar S 0, S1, S2, S3 and S4, so each cutting part can extend along positive y direction of principal axis and negative y direction of principal axis.In the space that is defined between planar S 1 and the S2, spiral component 1230 is not present in the y component in the negative zone.Therefore, the cutting part of cylinder V0 between planar S 1 and S2 (that is, along negative y direction of principal axis) extension downwards.Equally, in the space that is defined between planar S 3 and the S4, it is in the positive zone that spiral component 1230 is not present in the y component, therefore, the cutting part of cylinder V0 between planar S 3 and S4 can make progress (that is, along positive y direction of principal axis) extend.
On the other hand, in the space that is defined between planar S 0 and the S1, it is that positive zone and y component is in the zone of bearing that spiral component 1230 is present in the y component.Therefore, the cutting part of cylinder V0 between these planes can not extend along positive and negative y direction of principal axis.This is because spiral component 1230 is present on these two bearing of trends of cutting part.
As mentioned above, if whole spiral component 1230 be formed on spiral-shaped in, can not extend along any y direction of principal axis as the part of the cylinder that is arranged on the metal pattern in the spiral component to be formed 1230 so.Therefore, spiral component 1023 is improved to comprises two different pieces.Specifically, these two different parts are served as reasons as the first 1231 of the formation of the spiral camber in the spiral component 1230 and the second portion 1232 that is formed by the plane, and reason is as follows.
The section that Figure 15 A represents to be used to make the part of the metal pattern of spiral component 1023 moulding to dissect along the xy plane.
Metal pattern shown in Figure 15 A is solid V1, and its shape is by being divided into above-mentioned cylinder V0 solid V1, V2 and V3 and further removing solid V2 and V3 limits from V0 perpendicular to the planar S 5 of x axle and S6 with two.The x component of planar S 5 is " r1 ", and the x component of planar S 6 is " r1 "." r1 " is less than the radius r of cylinder V0.Because solid V2 and V3 are mutually symmetrical about initial point, so the following solid V2 that only describes saves the description to solid V3.Planar S 5 and S6 are therefore parallel to each other perpendicular to the x axle.Solid V1 is parallel to each other along the face of planar S 5 and S6 cutting.Therefore, when being parallel to the axial direction of z and looking, the part of the face that pass through solid V1 of spiral component 1023 and moulding is for linear and along direction extension parallel to each other.
Figure 15 B is the enlarged side view in the part of the spiral component 1023 that forms around solid V1 when being parallel to the axial direction of x and looking.Some P11, P12, P13 and P14 shown in Figure 15 B are positioned on the curve f1.Point P21, P22, P23 and P24 are positioned on the curve f2.Figure 15 B is illustrated in when look in the spirality inboard of spiral component by these area surrounded.In being clipped in the line L2 and the part between the L3 that is parallel to the z axle, solid V1 and V2 are cut apart each other by planar S 5.The y component of line L2 is-(r
2-r1
2)
1/2, the y component of line L3 is (r
2-r1
2)
1/2
On the other hand, remain on the curved surface of solid V1 by a P11, P12, P22 and P21 region surrounded and by a P13, P23, P24 and the moulding of P14 region surrounded, these zones are firsts 1231.The line segment of the line segment of the line segment of tie point P11 and P12, tie point P13 and P14, tie point P21 and P22 and the line segment of tie point P23 and P24 are corresponding to the edge of first 1231.These edges are all with respect to the angled α 1 of z axle.
Because second portion 1232 is parallel to the y axle, so the solid V1 that contacts with second portion 1232 can extend along positive and negative y direction of principal axis.On the other hand, first 1231 is present in the y component and is negative zone being arranged in part below the second portion 1232 on the negative y direction of principal axis.Therefore, the solid V1 that contacts with the described part of first 1231 can not extend along negative y direction of principal axis.Equally, first 1231 to be present in the y component be positive zone being arranged in part above the second portion 1232 on the positive y direction of principal axis.Therefore, the solid V1 that contacts with described part can not extend along positive y direction of principal axis.Therefore, the part that contacts with line segment between the P22 of solid V1 and the P12 of second portion 1232 needs to extend along positive y direction of principal axis.The part that solid V1 and the P13 of second portion 1232 contact with line segment between the P23 needs to extend along negative y direction of principal axis.Thereby solid V1 comprises the part that need extend along different directions respectively.Therefore solid V1 need be configured such that solid V1 is extended the planar S 10 of passing as cornerwise line segment P13-P22 of second portion 1232 and cuts apart.
B-5. the relation between the angle [alpha] 2 of Δ z and second portion 1232
As previously mentioned, be provided with the linear second portion 1232 that extends along direction parallel to each other substantially when looking with the direction of the axially parallel of turning axle 1021.In addition, adopt metal pattern, the planar S 10 that is positioned on the second portion 1232 when looking with the axial vertical direction of turning axle 1021 on the edge by this metal pattern utilization is cut apart spiral component 1023.Therefore, metal pattern can extend from the inboard of spiral component 1023.
Yet have a kind of situation, that is, the planar S 10 that extends through line segment P13-P22 becomes the above angle of 90 degree with respect to the z axle, and this depends on the magnitude relationship between above-mentioned angle and the z direction of principal axis thickness of indicating spiral component 1230.In this case, even metal pattern is cut apart by planar S 10, metal pattern can not extend from the inboard of spiral component 1023, and reason is as follows.
Figure 16 A is illustrated in each first 1231 to equal under the situation of each second portion 1232 with respect to the axial angle [alpha] 2 of turning axle 1021 with respect to the axial angle [alpha] 1 of turning axle 1021, the side view of the inboard of the spiral component 1023 of looking along the direction that is parallel to the x axle.Figure 16 B is the stereographic map of the state of representing that the spiral component shown in Figure 16 A 1023 wherein combines with the metal pattern that is used to make spiral component 1023 moulding.Figure 16 C is the cut-open view along the plane cutting of the rotation that comprises spiral component 1023, expression and identical state shown in Figure 16 B, and wherein spiral component 1023 combines with metal pattern.
If each first 1231 of spiral component 1023 is bigger with respect to the angle [alpha] 1 of z axle, there is such situation so, that is, the z component of the some P13 shown in Figure 15 B is less than the z component of a P22.In this case,, solid V1 is divided into two solids if being extended the plane of passing line segment P13-P22, these two solids of cutting apart direction interlock each other of extending respectively so along these two solids, thus prevent that the solid of cutting apart from extending.Therefore, the solid of cutting apart can not extend along any direction in the positive and negative y direction of principal axis.
Figure 17 A be illustrated in each first 1231 with respect to the axial angle [alpha] 1 of turning axle 1021 less than under the situation of each second portion 1232 with respect to the axial angle [alpha] 2 of turning axle 1021, the side view of the inboard of the spiral component 1023 of looking along the direction that is parallel to the x axle.Figure 17 B is the stereographic map of the state of representing that the spiral component shown in Figure 17 A 1023 wherein combines with the metal pattern that is used to make spiral component 1023 moulding.Figure 17 C is the cut-open view along the plane cutting of the rotation that comprises spiral component 1023, expression and identical state shown in Figure 17 B, and wherein spiral component 1023 combines with metal pattern.In Figure 17, the z component that the relation between Δ z and the angle [alpha] 2 is designed so that invocation point P13 is always greater than the z component of a P22.As a result,, solid V1 cuts apart the direction interlock each other that can not extend respectively along these two solids of these two solids of cutting apart so if being extended the plane of passing line segment P13-P22.Thereby these two solids of cutting apart all can suitably extend from spiral component 1023.
For the solid V1 as metal pattern is extended from spiral component 1023 as mentioned above, angle [alpha] 2 and Δ z need satisfy following expression 4:
Δz≤2·(r
2-r1
2)
1/2/tan?α2 …(4)
Figure 18 A is illustrated under the situation of z component greater than the z component of a P22 that angle [alpha] 1 equals angle [alpha] 2 and some P13, the side view of the inboard of the spiral component 1023 of looking along the direction that is parallel to the x axle.Figure 18 B is the cut-open view along the plane cutting of the rotation that comprises spiral component 1023, represents the state that the spiral component shown in Figure 18 A 1023 wherein combines with the metal pattern that is used to make spiral component 1023 moulding.If angle [alpha] 1 (=angle [alpha] 2) is enough little with respect to Δ z, is extended two solids the plane of passing line segment P13-P22 cutting apart so and can cut apart the direction interlock each other that solid extends respectively along described.Thereby these two solids of cutting apart all can suitably extend along one of positive and negative y direction of principal axis.In other words, according to second embodiment, each second portion 1232 that is arranged in the spiral component 1023 does not need always less than the angle [alpha] 1 of each first 1231 with respect to axial c with respect to the angle of the axial c of turning axle 1021.When looking with the direction of the axially parallel of turning axle 1021,1232 of second portions need be along direction linear extension parallel to each other.
B-6. the structure of metal pattern
Under the situation of moulding spiral component 1023 only, the metal pattern that is made of the solid V1 with above-mentioned shape only needs to extend from the inboard of spiral component 1023.Yet if spiral component 1020 is connected to turning axle 1021 by back up pad 1024, turning axle 1021 and back up pad 1024 need moulding in solid V1 so.
Figure 19 represents to be used for as mentioned above the mould of moulding turning axle 1021 and back up pad 1024.Shown in Figure 19 A, planar S 7 extends through the some P13 and the P22 of second portion 1232, and is parallel to the x axle.Solid V1 is divided into solid V1L (left side among the figure) and V1R (right side among the figure) by planar S 7.Solid V1L and V1R are mutually symmetrical, and therefore only describe solid V1R below.Solid V1R is the part that will extend downwardly into y axle minus side of metal pattern.Yet the zone up to back up pad 1024 of drawing shade by oblique line among the figure can not be extended downwards, because turning axle 1021 is present in downside.
Figure 19 B is along perpendicular to the cut-open views z axle and solid V1R 8 cuttings of the crossing planar S of above-mentioned zone (drawing shade by oblique line).Solid V5 shown in the figure is the part of solid V1R, and by obtaining from solid V1R excision one zone.This width of waiting to excise the zone equals turning axle 1021 along the axial width of x, and y component that should the zone is for just.In addition, solid V4 obtains by removing solid V5 from solid V1R.After solid V4 extended downwards, solid V5 can be along extending upward away from back up pad 1024R travel direction.
Thereby solid V1R is further divided into solid V4 and V5.Like this, metal pattern can with by separating with the transmission member that back up pad 1024 constitutes with the integrally formed spiral component 1023 of turning axle 1021.
As mentioned above, solid V1R is divided into solid V4 and V5, thus they can be respectively downwards and extend upward.Equally, solid V1L is divided into and can distinguishes up and down the solid that extends.Thereby the solid of cutting apart of each solid V1L and V1R can be the metal pattern that separates according to bearing of trend.
Figure 20 is a stereographic map of representing as mentioned above the parts that extend from the metal pattern as solid downwards.As shown in the figure, metal pattern has zigzag on the whole.These moulds and treat that upwardly extending mould is engaged with each other from downside and upside respectively are to be formed for a mould of transmission member 1020.
B-7. the operation of back up pad and function
To refer back to operation and function that Figure 11 describes back up pad 1024 below.As previously mentioned, spiral component 1023 comprises first 1231 and second portion 1232.Spiral component 1023 be shaped to make each second portion 1232 with respect to the axial angle [alpha] 2 of turning axle 1021 less than the axial angle [alpha] 1 of each first 1231 with respect to turning axle 1021.
Because on the developer of action of gravity in being filled in vessel, so its lowermost position of developer in vessel more and more is compacted.As shown in figure 11, when spiral component 1023 when the direction shown in the arrow D is rotated, spiral component 1023 owing to the inertial force of developer be subjected to along and the upward reaction force in the opposite direction of side shown in the arrow D.For example, right zone in the drawings, spiral component 1023 is subjected to the fully upwards reacting force Fu of effect.Zone, a left side in the drawings, spiral component 1023 is subjected to the reacting force Fd of effect fully downwards.
C. the 3rd embodiment
The 3rd embodiment of the present invention will be described subsequently.The structure of the 3rd embodiment and operation have a lot of common traits with second embodiment.Therefore, only describe the difference of the 3rd embodiment and second embodiment below, omit description common trait.
At first, the difference of the 3rd embodiment and second embodiment is that cylinder V0 just in time is as the solid V1 that keeps the metal pattern of spiral component 1023 from the inboard.That is, in the 3rd embodiment, first 1231 and second portion 1232 all are spiral-shaped.
The difference of the 3rd embodiment and second embodiment also is, the planar S 10 that solid V1 is divided into solid V1L and V1R does not extend through the diagonal line P13-P22 of each second portion 1232.
Figure 21 represents solid V1 is divided into relation between the second portion 1232 of the planar S 10 of solid V1L and V1R and spiral component 1023.As shown in figure 21, second portion 1232 comprises the some P15 as the point on the line of tie point P12 and P13, and as the some P25 of the point on the line of tie point P22 and P23.In the 3rd embodiment, the planar S 10 of cutting apart solid V1 extends through the line of tie point P15 and P25.At this moment, the solid V1 planar S 10 that is used as the border is divided into solid V1L and V1R.As shown in the figure, the angle Y between the line of z axle and tie point P15 and P25 is acute angle (90〉Y〉0) or 90 degree.Therefore, solid V1L can make progress (towards the positive side of y axle) extend and solid V1R (towards y axle minus side) extension downwards.
Below will about can how to extend easily solid V1L and V1R describe each second portion 1232 and turning axle 1021 axially between angle.Figure 22 represents second portion 1232-2 and the 1232-3 as two embodiment, and with reference to these embodiment illustrated each second portion 1232 and turning axle 1021 axially between the influence of angle.Second portion 1232-2 is α 2 with respect to the axial angle of turning axle 1021.Second portion 1232-3 is α 3 with respect to the axial angle of turning axle 1021.Between angle [alpha] 2 and α 3, have the angular dimension relation: 90 ° 〉=γ〉α 2〉α 3〉0.
In this case, the angle φ between angle φ 2 between second portion 1232-2 and the planar S 10 and second portion 1232-3 and the planar S 10 3 is represented by following formula.
φ2＝γ-α2， φ3＝γ-α3 …(4)
Second portion 1232-2 has identical thickness W with 1232-3.In addition, as shown in figure 22, the contact length that second portion 1232-2 contacts with outward flange as the planar S 10 of the cut surface of solid V1 is T2.Another contact length that second portion 1232-3 contacts with outward flange is T3.By used thickness W and angle φ 2 and φ 3 length T 2 and T3 are expressed as follows.
T2＝W/sinφ2， T3＝W/sinφ3 …(5)
From the above-mentioned angular dimension relation between γ, α 2 and the α 3 as can be known, α 2 and α 3 satisfy 90 °〉α 2〉α 3〉0.Therefore, obtain sin φ 3〉sin φ 2.Thereby it is T2 that the length scale between T2 and the T3 is closed〉T3.Therefore, when second portion 1232 and turning axle 1021 axially between angle when reducing, the contact length shortening that second portion 1232 contacts with the outward flange of metal pattern (solid V1).Contact length is long more, is needing the distance of moving metal mould long more on every side when second portion 1232 is pulled out on metal pattern.That is, when contact length increased, metal pattern was difficult to extend more.In other words, metal pattern easier extension when contact length reduces.Can by set less angle as each second portion 1232 and turning axle 1021 axially between angle make the easier extension of metal pattern.Specifically, spiral component 1023 is formed from a resin usually, therefore has plasticity to a certain extent.Thereby, can make metal pattern extension slightly easily by locate further to shorten the part that spiral component 1023 contacts with the outward flange of the cut surface of metal pattern in each this low angle part (for example, second portion 1232).Thereby, fully being out of shape or warpage iff compliant spiral component 1023, metal pattern can extend satisfactorily so.
In aforementioned second embodiment,, be arranged on second portion 1232 in the spiral component 1023 along direction linear extension parallel to each other when when being parallel to turning axle 1021 axial directions and looking.Yet, if cut apart the diagonal line P13-P22 that does not need to extend through each second portion 1232 as the planar S 10 of the solid V1 of the metal pattern that keeps spiral component 1023 from the inboard, second portion 1232 not may need to be formed in when edge direction linear extension parallel to each other substantially when being parallel to turning axle 1021 axial directions and looking so.Promptly, even each second portion 1232 is when along being parallel to the arc that is similar to first 1231 when turning axle 1021 axial directions are looked, each second portion 1232 is also enough less than each first 1231 angle axial with respect to turning axle 1021 with respect to the axial angle of turning axle 1021.
D. modified example
Above embodiment can carry out following modification.But plural above-mentioned embodiment and following modification combination with one another are used.
D-1. the method that is used for turning axle 21 is connected to spiral component 23 is not limited to the described method of first embodiment.In the first embodiment, turning axle 21 is connected at high angle part 231 places by stirring plate 24 with spiral component 23.Yet according to a modified example, turning axle 21 can be connected at low angle part 232 places with spiral component 23.Fig. 6 is the cut-open view of the critical piece in this modified example.As shown in Figure 6, when spiral component 23 when the direction shown in the arrow D is rotated, spiral component 23 lower right area in the drawings is subjected to reacting force Fu upwards owing to the inertial force of developer.Simultaneously, spiral component 23 zone, lower-left in the drawings is subjected to downward reacting force Fd.Fig. 7 represents the spiral component 23 when low angle part 232 is positioned at the vessel bottom.At this moment, in the lower right area in the drawings, the boundary portion E1 between low angle part 232 and the high angle part 231 is subjected to the reacting force Fu that makes progress from developer.In the zone, lower-left in the drawings, the boundary portion E2 between low angle part 232 and another high angle part 231 is subjected to the downward reacting force Fd from developer.Thereby low angle part 232 is subjected to sometimes simultaneously along the reacting force of different directions effect, thus cause probably the distortion or break.
In this embodiment, low angle part 232 is connected to turning axle 21 by the web joint 25 as the embodiment of second link.When being parallel to turning axle 21 axial directions and looking, web joint 25 and stir plate 24 and intersect with 90 degree each other.This structure can be born along the reacting force of different directions effect or the shearing force that produces between low angle part 232 and vessel inwall, also is like this even described reacting force or shearing force act on the low angle part 232.This is because low angle part 232 is connected on the turning axle 21 securely by above-mentioned web joint 25.That is, being connected low angle part 232 that plate 25 supports has improved the intensity of spiral component 23 and prevents distortion and/or break.As a result, spiral component 23 developer that can easily loosen and be compacted.Web joint 25 can only be set as the member that turning axle 21 is connected to spiral component 23, replace being provided with stirring plate 24.
D-2., the position that each low angle part 232 is set in spiral component 23 is not limited to the described position of first embodiment.In the first embodiment, when when being parallel to axial direction and looking, turning axle 21 axially on measure 180 degree angles between two adjacent stirring plate 24A adjacent one another are and the 24B.For each sections between the top that is clipped in per two adjacent stirring plate 24A and 24B a low angle part 232 is set.That is, between the perpendicular line that extends to turning axle 21 from per two low angle parts 232 axial adjacent one another are, keep 180 degree angles along turning axle 21.Yet low angle part 232 is arranged so that alternatively described perpendicular line becomes 120 degree to extend relative to each other.In this structure, the quantitative proportion of the low angle part 232 that the per unit length of spiral component 23 is provided with increases.When this ratio increases, distributed dispersedly from the load that the developer that is compacted applies at the initial driving state, make the intensity of transmission member 20 improve.In addition, the amount of the developer that fill can be decreased to below half of total measurement (volume) of vessel of toner Cartridge 10.
In above embodiment, when when the axial direction that is parallel to turning axle 21 is looked, each low angle part 232 axially becomes an angle of 90 degrees to locate with respect to stirring plate 24A around turning axle 21 with 24B.Yet this angle is not limited to 90 degree.In brief, stirring plate 24 all only need be connected to the optional position on the high angle part 231 that is clipped between per two low angle parts 232.
D-3. it is described that the number of types that constitutes the part of spiral component 23 is not limited to first embodiment.In the first embodiment, spiral component 23 partly is made of two classes, that is, and and high angle part 231 and low angle part 232.Yet spiral component 23 can comprise the 3rd class part, and its axial angle with respect to turning axle 21 is different with low angle part 232 with high angle part 231.At the different part of these types join domain connected to one another place, form ridge naturally as the border between the dissimilar part that is connected.Yet the part that these types are different can be connected to each other to smooth and continuous.In brief, spiral component 23 only needs to comprise dissimilar parts, they with respect to the axial angle of turning axle 21 respectively according to the type of these parts and difference.
