Because an end of leaf spring 90 (at rear wall 42 side places) is fixed; And the other end of leaf spring 90 (at antetheca 40 side places) is a free end; And because leaf spring 90 processed by elastomeric material, so when quilt during from following extruding, counter clockwise direction 96 strains of leaf spring 90 in Fig. 3.In other words, move pivotally on first one 91 and second ones 92 borders 95 that are centered around between second one 92 and the 3rd one 93, thereby first one 91 and second ones 92 are received in the recess 94.
As shown in Fig. 3, the first angle θ
1Be defined in the dotted line and first one 91 upper surface or the angle between the lower surface that extend along the lower surface of diapire 41, and the second angle θ
2Be defined in this dotted line and second one 92 upper surface or the angle between the lower surface.Here, the second angle θ
2Greater than the first angle θ
1In other words, second one 92 more precipitous with respect to this dotted line than first one 91.
Obviously, first one 91 and second ones 92 combination provides crooked bight to be oriented to be lower than the V-arrangement shape of remainder.In other words, the combined shaped of first area 91 and second area 92 is outstanding towards the diapire 107 of box mounting portion 110 from diapire 41.First one 91 lower surface corresponding to first guiding surface and second one's 92 lower surface corresponding to second guiding surface.
In the above-described embodiments, bonding part (leaf spring 90) has smooth last segmented surface and following segmented surface.Yet arcuate surfaces or spherical surface also are available.In addition, in the embodiment that is described, leaf spring 90 is set at diapire 41 places with recess 94.Yet these can be set in roof 39 and the sidewall 83,84.
The box body 31 of print cartridge 30 can have franking, and this franking stipulates that the user contacts the used cramping zone of print cartridge 30.Alternately, slip-proofing device is set at box body 31, and perhaps part ground forms anti-skidding shape so that user's finger cramping box body 31 in the neighboring of box body 31.For example, the convexity 74 that in Fig. 6, is shown in broken lines can be set for the fingers part.Protruding 74 is outstanding along removing direction 55 from rear wall 42.In addition, protruding 74 vertical positions that are between the upper end of vertual (virtual) horizontal line 54 and box body 31.Through protruding 74, can easily carry out installation and the removing from box mounting portion 110 of print cartridge 30 in the body mounting portion 110 by the user's finger cramping.
The process of the fitting operation of print cartridge 30 in the box mounting portion 110 will be described with reference to figure 6 to Fig. 8.
As shown in Fig. 7, after opening the cover (not shown) that normally covers opening 112, print cartridge 30 is aimed at opening 112, thereby antetheca 40 is in along the front side of installation direction 56.For print cartridge 30 is installed, the user is with the part of his finger grip box body 31, and this part is near rear wall 42.The part by finger grip of box body 31 is not confirmed.Yet, according to the load mode of imagination or hypothesis, suppose that printer 10 often is installed on user's the desk, print cartridge 30 is inserted in the box mounting portion 110 be accompanied by the opening 112 that the user watches box mounting portion 110 downwards attentively.Therefore, the user can be located at the part in the zone of expanding between vertical core and the upper part of box body 31 through his finger cramping commonly used.
In the starting stage that print cartridge 30 is inserted in the box mounting portion 110, the top of leader 35 (fore-end) contacts with bar part 145.When print cartridge 30 was further inserted in the box mounting portion 110, the crimping section 146 of bar part 145 rode on leader 35.Therefore, bar part 145 is pivotally moved along the counter clockwise direction among Fig. 8.,, print cartridge 30 promotes downwards so being held mechanism 144 because thereby bar part 145 is pivotally moved along clockwise direction by the biasing force bias voltage of helical spring 148.Therefore, leaf spring 90 contacts with the upper surface of the diapire 107 of shell 101.Correspondingly, as shown in figure 8 wherein, this upper surface makes first 91 and second 92 strain of leaf spring 90, thereby makes first one 91 and second ones 92 to be received in the recess 94.
When print cartridge 30 was further inserted in the box mounting portion 110, the top 75 of projection 46 (specified interface) was connected to by the slide unit 135 of helical spring 139 towards opening 112 bias voltages.Then, print cartridge 30 is resisted the biasing force of helical springs 139 and is further inserted box mounting portion 110.That is, require the user further to promote the rear wall 42 of print cartridge 30 forward along installation direction 56.Thus, the biasing force of the helical spring 139 installation speed that reduced (mitigation).
As shown in figure 6, when print cartridge 30 was further inserted in the box mounting portion 110, the recess 94 of print cartridge 30 was aimed at the conjugate foramen 108 of box mounting portion 110.Therefore, not having any extruding force is applied on the leaf spring 90 from diapire 107.As a result, the leaf spring 90 that is received in the recess 94 is received in the conjugate foramen 108 to recover initial attitude shown in Figure 3 then.As a result, form with the boundary edge of the formation conjugate foramen 108 of diapire 107 for second one 92 and engage.
Under state shown in Figure 6, print cartridge 30 via projection 46 by the biasing force of helical spring 139 along removing direction 55 bias voltages.Therefore, leave print cartridge 30 if the user discharges his finger, then print cartridge 30 is promoted along removing direction 55 by helical spring 139.Yet,,, keep installment state shown in Figure 6 thus so can suppress print cartridge 30 along the displacement that removes direction 55 because second one 92 boundary edge with conjugate foramen 108 contacts.In other words, leaf spring 90 keeps the installment state of print cartridge 30 as illustrated in fig. 6 with the biasing force that engages opposing helical spring 139 of conjugate foramen 108.
When the user utilize he finger cramping print cartridge 30 rear wall 42 and when removing direction 55 and pull out the print cartridge of being installed fully 30; The boundary edge that is engaged hole 108 for second one 92 promotes, thus leaf spring 90 by strain pivotally to move along direction by 96 signals of the arrow among Fig. 3.Thus, leaf spring 90 breaks away from and is received in the recess 94 from the boundary edge of conjugate foramen 108.At this moment, as shown in figure 8 wherein, at least one part of leaf spring 90 is arranged in recess 94.
Because leaf spring 90 is received in the recess 94, the user can be along removing direction 55 pulling print cartridges 30.Print cartridge 30 is pulled out from box mounting portion 110 through opening 112 by the user then, so that state shown in Figure 7 to be provided.
In the above-described embodiments, maintaining body 144 is not locked in installation site completely with print cartridge 30, but pushes print cartridge 30 downwards.In other words, between maintaining body 144 and print cartridge 30, any locking mechanism is not set.Therefore, even if maintaining body 144 is damaged or destroys, also can carry out print cartridge 30 in the box mounting portion 110 loading and from the unloading of box mounting portion 110.
In addition; If the biasing force of the helical spring 148 in maintaining body 144 is enough greatly to move down print cartridge 30; Diapire 41 is contacted with the diapire 107 of shell 101, the frictional force that then between the diapire 107 of the diapire 41 of print cartridge 30 and shell 101, produces along installation direction 56 can become greater than helical spring 139 along the biasing force that removes direction 55 effects.As a result, can keep the installment state of box 30 in box mounting portion 110.
In addition, when print cartridge 30 was inserted in the box mounting portion 110 incipiently, first one 91 was promoted by the upper surface of diapire 107, between second one 92 of leaf spring 90 and this upper surface, produced frictional force thus.Elasticity through selecting leaf spring 90 or select is linked in the frictional force of second one 92 material of leaf spring 90, and the frictional force between the upper surface of second one 92 of leaf spring 90 and diapire 107 (coefficient of friction that is produced by second area 92) can be greater than the biasing force of helical spring 139.As a result, print cartridge 30 can be maintained at the installation site in the box mounting portion 110.
In addition, as shown in Fig. 3, the second angle θ
2Greater than the first angle θ
1Usually, when leaf spring 90 was pushed by the diapire 107 of box mounting portion 110, if these angles are less, then strain can easily take place in leaf spring 90.Therefore; With help second one 92 by diapire 107 crimps, box 30 compares from the needed power of removing of box mounting portion 110, help first one 91 by diapire 107 crimps, print cartridge 30 can carry out through littler power to the installation process in the box mounting portion 110.
Hereinafter, will utilize accompanying drawing to describe other embodiments of the invention, wherein similarly part and member by marking to avoid repeat specification with those identical Reference numerals of first embodiment.

To the print cartridge 30C according to fourth embodiment of the invention be described with reference to Figure 11 and Figure 12.In the 4th embodiment, box body 31C is formed with the projection 125 as the bonding part on the lower surface of diapire 41.
More specifically, projection 125 has arc spherical surface and is arranged in the outer surface of the diapire 41 of print cartridge 30C, promptly is arranged in the lower surface place of box body 31C.When print cartridge 30C inserted box mounting portion 110, projection 125 was set at the position relative with conjugate foramen 108.As shown in Figure 12, when being mentioned a little, print cartridge 30C is installed in the box mounting portion 110 or from box mounting portion 110, is removed.When print cartridge 30C was installed in the box mounting portion 110, projection 125 engaged with conjugate foramen 108.
In the 4th embodiment, projection 125 is arranged in diapire 41, and still, this projection can be arranged in roof 39, perhaps is arranged in sidewall 83,84.
The bonding part can relatively be arranged in a surface in the surface (outer surface roof 39, diapire 41, antetheca 40 or sidewall 83,84) with the through hole that in the inner rim (that is, roof 111, diapire 107, pair of sidewalls 115,116 or end wall 104) of box mounting portion 110, forms or opening (conjugate foramen 108 among the 4th embodiment), recess (not shown) or protruding (not shown).The surface (outer surface of roof 39, diapire 41, antetheca 40 or sidewall 83,84) that is furnished with the bonding part is corresponding to first surface.The bonding part is forming with the shape of through hole (opening), recess or bump bonds.And then, thereby can being arranged in the first surface place, the bonding part can engage with the adjacent panel 102 of the inner space of partition box mounting portion 110.
Under the installment state of print cartridge 30C in box mounting portion 110, print cartridge 30C is along removing direction 55 by slide unit 135 and helical spring 139 bias voltages.Yet; In the 4th embodiment; Through engaging of the projection 125 (perhaps can be through hole, opening, projection or recess) of print cartridge 30C and the conjugate foramen 108 of box mounting portion 110 (perhaps consistent with the shape of corresponding bonding part projection, recess, opening or protruding), print cartridge 30C can bear the biasing force of slide unit 135 and helical spring 139.As a result, print cartridge 30C can be maintained at the installation site.
Be formed with recess or opening except conjugate foramen 108 like compartmentalized box for holding assorted fruits and candies mounting portion 110, then recess 94 can (alternative projection 125 ground) be set at and this recess or the relative position of opening with leaf spring 90.
When in the plate 102 of roof 111, diapire 107, end wall 104, this pair of sidewalls 115,116 and box mounting portion 110 at least one convexity being set; The bonding part of print cartridge 30C can be to have and to be set on this at least one outer surface in the outer surface of roof 39, diapire 41, antetheca 40 and sidewall 83,84 of box body 31, with relative with this convexity with the recess of the shape of bump bonds.
To the print cartridge 30D according to fifth embodiment of the invention be described with reference to Figure 13.In the 5th embodiment, leader 44D has the shape of the leader 44 that is different from previous embodiment and is used as the bonding part.Leader 35 remains unchanged and can be used on the print cartridge 30D.
Leader 44D is outstanding downwards from diapire 41.As shown in Figure 13, leader 44D have along vertical direction 52 and depth direction 53 extend and transversely direction 51 towards each other a pair of side surface 77,78.Box mounting portion 110 is formed with and has along the pair of sidewalls 76A of installation direction 56 extensions, the guiding groove 109 of 76B.Side surface 77 is relative with sidewall 76A, and side surface 78 is relative with sidewall 76B.This a pair of side surface 77,78 transversely direction 51 between the sidewall 76A of guiding groove 109,76B.That is, the width of leader 44D is less than the width of guiding groove 109.Side surface 77 along installation direction 56 forward and transversely direction 51 outwards extend obliquely, thereby side surface 77 moves closer to sidewall 76A along installation direction 56.Side surface 78 along installation direction 56 forward and transversely direction 51 lean outward and tiltedly extend, thereby sidewall 76B moves closer to side surface 78 along installation direction 56.In other words, the width of leader 44D increases towards antetheca 40 along installation direction 56 gradually.Side surface 77 has the part 77A adjacent with antetheca 40, and part 77A contacts with sidewall 76A.Side surface 78 has the part 78A adjacent with antetheca 40, and part 78A forms with side surface 76B and contacts.The part 78A of the part 77A of side surface 77 and side surface 78 has sufficient area tolerance (square measure) thereby the box body 31 that suppresses to be installed in the box mounting portion 110 with the biasing force of opposing bias voltage box body 31 moves removing on the direction 55.
In this embodiment, side surface 77,78 has flat surfaces (surface), but as side surface 77,78, the scalariform surface also is suitable for.
When print cartridge 30D was installed in the box mounting portion 110 or from box mounting portion 110, is removed, the part 77A of side surface 77,78,78A contacted with sidewall 76A, 76B respectively.As a result, produced the frictional force of the load of the biasing force that applies opposing slide unit 135 and helical spring 139.Therefore, print cartridge 30D can be maintained at installed position.The guiding groove 109 that can engage with leader 44D (bonding part) is corresponding to the sticking department among the 5th embodiment.
Shown in Figure 14 according to the print cartridge 30E of sixth embodiment of the invention.As shown in Figure 14, deadlock lever 151 also can be used as the bonding part.Deadlock lever 151 can be arranged in a place in roof 39, diapire 41 and the sidewall 83,84 of print cartridge 30E.In Figure 14, deadlock lever 15 is disposed in recess 94 places that form in the diapire 41.
In addition, deadlock lever 151 is urged the parts (not shown) along direction 153 pushings.For example adopt torque spring as push part.Torque spring comprises coiler part and two arm portions that extend from each end of coiler part.Coiler part is set at pivot.Thereby two arm portions are connected to the angle that deadlock lever 151 limits along direction 153 bias voltage deadlock levers 151.
When print cartridge 30E was not installed in the box mounting portion 110, deadlock lever 151 was in the primary importance.When print cartridge 30E just had been inserted in the box mounting portion 110, deadlock lever 151 was promoted by the diapire 107 of box mounting portion 110, thus the second place is changed into from primary importance in its position.Relatively the time, thereby deadlock lever 151 is changed into primary importance with its position from the second place to the recess 94 that further is inserted into print cartridge 30 in the box mounting portion 110 as print cartridge 30E once more with the conjugate foramen 108 of box mounting portion 110.As a result, print cartridge 30E can be maintained at installed position.The recess 94 that can engage with deadlock lever 151 (bonding part) is corresponding to the sticking department among the 6th embodiment.
When print cartridge 30E by when box mounting portion 110 removes, print cartridge 30E is drawn out along removing direction 55 under the state that is a little upwards promoted by the user.That is, in the 6th embodiment, with mode among Figure 10 cotype mutually, the height of print cartridge 30E is less than the height of print cartridge 30 shown in Figure 3.
In the 6th embodiment, deadlock lever 151 is set on the print cartridge 30E.Yet deadlock lever 151 can be set at (for example, on the conjugate foramen 108) on the box mounting portion 110.
Shown in Figure 15 according to the print cartridge 30F of seventh embodiment of the invention.As shown in FIG. 15, deadlock lever 151F that can strain extends and has a basic end on the front portion of the diapire 41 that flexibly is supported on print cartridge 30F at least along depth direction 53.Deadlock lever 151F comprises the locking handle 155 that is set at the free end place opposite with basic end, and projection 156 act as the locking pawl.In this embodiment, locking pawl 156 is as the bonding part.Be installed under the installment state in the box mounting portion 110 at print cartridge 30F, locking handle 155 is outstanding from the opening 112 of box mounting portion 110.In addition, be installed under the installment state in the box mounting portion 110 at print cartridge 30F, a surface of locking pawl 156 is to the boundary edge of the diapire 107 of formation conjugate foramen 108, and locking pawl 156 engages with conjugate foramen 108.Can with locking pawl 156 (bonding part) engaging hole engaged 108 corresponding to the sticking department among the 7th embodiment.
When print cartridge 30F by 110 whens unloading from the box mounting portion, user's handling roof 39 is with locking handle 155 and be pulled upwardly box body 31F, and locking pawl 156 is broken away from from the boundary edge of conjugate foramen 108.If the user discharges locking handle 155, then locking handle 155 flexibly moves down with the boundary edge of engage latch pawl 156 with conjugate foramen 108.In the 7th embodiment, identical with mode among Figure 10 and Figure 14, the height of print cartridge 30F is less than the height of print cartridge 30 shown in Figure 3.Therefore, the upwards pivoting action of locking handle 155 makes locking pawl 156 to break away from from the boundary edge of conjugate foramen 108.In addition, because slide unit 135 extruding projections 46, so print cartridge 30F is along removing direction 55 by 110 releases from the box mounting portion.Therefore, deadlock lever 151F helps the user to remove print cartridge 30F from box mounting portion 110.
In the 7th embodiment, deadlock lever 151F is arranged in diapire 41 places, but can be arranged in a place in roof 39, antetheca 40 and the sidewall 83,84 of print cartridge 30F.In arbitrary situation, deadlock lever 151F can for example plate 102, guiding groove 109 and rod 124 engage with a part of box mounting portion 110.
It is contemplated that various modification.
< first modification >
Print cartridge is being inserted in the box mounting portion 110 or removing the process of print cartridge from box mounting portion 110, it is big and apply the frictional force of the resistant load of resisting biasing force that the CONTACT WITH FRICTION of the inner rim of bonding part and box mounting portion 110 (roof 111, diapire 107, antetheca 40, this pair of sidewalls 115,116) can produce biasing force than helical spring 139.As long as can produce this frictional force, just the bonding part is not limited to leaf spring 90.
For example, elastomeric element for example rubber can be used as the bonding part.Elastomeric element can be set at like the lower part and locate: when print cartridge was installed in the box mounting portion 110 or from box mounting portion 110, is removed, the bonding part formed with the inner rim of box mounting portion 110 herein and contacts.Elastomeric element is set at least one outer surface in the outer surface of roof 39, diapire 41, antetheca 40, sidewall 83,84, leader 35 and leader 44 and is stretched along this outer surface.Here, this outer surface be when print cartridge be loaded onto in the box mounting portion 110 or by the inner rim of during 110 unloadings and box mounting portion 110 from the box mounting portion over against the surface.As stated, the bonding part forms at least one in the surface that the part that contacts is roof 39, diapire 41, antetheca 40 and sidewall 83,84 with the inner rim of box mounting portion 110 herein.When print cartridge was installed in the box mounting portion 110, the elastomeric element that is set on the outer surface of print cartridge formed tight the contact with the inner rim of box mounting portion 110, produces frictional force thus.
Yet, can exempt elastomeric element.When not having the elastomeric element that is arranged at outer surface, can produce frictional force with direct contact of the inner rim of box mounting portion 110 through the outer surface of print cartridge.
In addition, elastomeric element can be set at the outer surface of ink-supplying part 37.As shown in Figure 6, when being installed to print cartridge 30 in the box mounting portion 110, ink-supplying part 37 is inserted into tubular retaining part 121.As a result, the elastomeric element that is set at the outer surface place of ink-supplying part 37 closely contacts with the interior perimeter surface of retaining part 121, produces frictional force thus.
In addition, elastomeric element can be set at the interior perimeter surface of air communication passage 32a.As shown in Figure 6, when inserting print cartridge 30 in the box mounting portion 110, rod 124 is inserted among the air communication passage 32a.As a result, the elastomeric element that is set at the interior perimeter surface place of air communication passage 32a closely contacts with the outer surface of rod 124, produces frictional force thus.The part surface that is set at the interior perimeter surface of air communication passage 32a thereby elastomeric element is not set at the whole interior perimeter surface place of air communication passage 32a allows air and atmosphere in the ink chamber 36 when print cartridge 30 is installed in the box mounting portion 110.
In addition, be set in the situation of an outer surface in the outer surface except antetheca 40 in the print cartridge at air communication passage 32a, elastomeric element can be set at antetheca 40 places.Particularly, antetheca 40 can be formed with hole, opening or the recess that is used to arrange elastomeric element.A part of box mounting portion 110 (for example, rod 124) can engage with the hole, opening or the recess that on antetheca 40, form.
In addition, elastomeric element can be set at these pair of sidewalls 85,86 places's (shown in Figure 2) of test section 33.Be installed under the installment state in the box mounting portion 110 at print cartridge 30, sidewall 85,86 respectively with lid 105,106 over against (shown in Figure 5).Therefore, the elastomeric element that is set at these pair of sidewalls 85,86 places closely contacts with lid 105,106, produces frictional force thus.For the inherent function (being used for the function of transmission from the light of optical pickocff 114 emissions) that does not damage test section 33, elastomeric element is set at the part (part outside the light institute irradiation area of optical pickocff 114 emissions) of the sidewall 85,86 of test section 33 and locates.
In addition, the leaf spring 90 of first embodiment can be applied to elastomeric element.Like what with reference to figure 8 time, describe, when print cartridge 30 just is being inserted in the box mounting portion 110, thereby first guide portion 91 of leaf spring 90 is pushed by strain by the diapire 107 towards box mounting portion 110.Because this strain, first guide portion 91 is accommodated in the recess 94.At this moment, first leader 91 contacts with diapire 107 pressure, produces frictional force thus.
In above-mentioned first modification, the CONTACT WITH FRICTION of the inner rim of bonding part and box mounting portion 110 can produce greater than the biasing force that produces by helical spring 139, along the frictional force of installation direction 56.As a result, this frictional force can be resisted the biasing force of helical spring 139 and prevented that print cartridge from moving along removing direction 55.
< second modification >
As the bonding part, also can adopt like lower component: the frictional force that these parts act on when print cartridge is installed in the box mounting portion 110 less than print cartridge by the frictional force of 110 when unloading effects from the box mounting portion.
For example, as the bonding part, the parts (perhaps slip-proofing device) with high frictional behavior also are available.This high friction means is included in a plurality of convexities that form in the presumptive area like the lower part: be installed in the box mounting portion 110 or by when box mounting portion 110 removes, this part place, bonding part contacts with 110 formation of box mounting portion at print cartridge.
Here, identical with the mode of first modification, the bonding part forms at least one outer surface in the outer surface that the part that contacts the place is roof 39, diapire 41, antetheca 40 and sidewall 83,84 with box mounting portion 110.
Second skewed surface that each convexity of high friction means has first skewed surface and extends from first skewed surface.First skewed surface is by directed and extend down along installation direction 56 is oblique along removing direction 55.Second skewed surface is by directed along installation direction 56 and extend down towards rear wall 42 is oblique.
The angular that between first skewed surface and outer surface, limits is greater than the 4th angle that between second skewed surface and outer surface, limits.That is, first skewed surface is more precipitous than second skewed surface with respect to outer surface.
