Before print cartridge 30 is inserted into box mounting portion 110, valve 77 closes ink supply opening 71.When print cartridge 30 is inserted into box When in mounting portion 110, black supply pipe 102 enters ink supply opening 71.When it happens, in seal member 76 by black supply pipe While 102 outer surface is resiliently deformed, the inner surface for limiting the seal member 76 of ink supply opening 71 contacts fluid tightly The outer surface of black supply pipe 102.When print cartridge 30 is further inserted into, the end of black supply pipe 102 is open 71 simultaneously across ink supply And contact valve 77.When print cartridge 30 is further inserted into, black supply pipe 102 is with resisting the pushing force of helical spring 78 backward Promotion and mobile valve 77 on direction 58.When it happens, ink is allowed through the inner space of cylindrical wall 73 from ink chamber 36 It flow to black supply pipe 102.Although being not shown in drawing, black supply pipe 102 has at the end of black supply pipe 102 Or the adjacent opening in end with black supply pipe 102, and the opening extends to black supply from the outer surface of black supply pipe 102 The inner space of pipe 102.Ink flow to black supply pipe 102 from the inner space of cylindrical wall 73 via the opening of black supply pipe 102 Inner space.Ink flow to ink from ink chamber 36 by the inner space of cylindrical wall 73 and the inner space of black supply pipe 102 The outside of box 30.

Black supply department 34 can not necessarily include valve 77 and helical spring 78.For example, in another embodiment, ink supply is opened Mouth 71 can be closed with envelope.In such an embodiment, when print cartridge 30 is inserted into box mounting portion 110, black supply pipe 102 is passed through It wears the film and passes through ink supply opening 71, so that the end of black supply pipe 102 is located in the inner space of cylindrical wall 73.Another In embodiment, the elasticity that can use seal member 76 closes ink supply opening 71.In such an embodiment, when print cartridge 30 is inserted When entering in box mounting portion 110, the outer surface of black supply pipe 102 radially pushes the seal member 76 for limiting ink supply opening 71 Inner surface, and thus open ink supply opening 71.

With reference to Fig. 6, inner frame 35 includes test section 62, and test section 62 is from inner frame 35 in upward direction 54 Extend above.Test section 62 is protrusion, is had and the continuous inner space of ink chamber 36.Test section 62 is configured to allow for Light passes through there in right direction 55 and left direction 56.Test section 62 is by the opening 98 of front cover 32 to the outside of print cartridge 30 Extend.

With reference to Fig. 6, print cartridge 30 includes detection part 59, and detection part 59 is located in ink chamber 36.Inner frame 35 includes Pivotal axis 61, pivotal axis 61 extend in right direction 55 and left direction 56, and detection part 59 is by pivotal axis 61 Support enables detection part 59 to pivot around pivotal axis 61.

Test section 59 includes float 63, and the specific gravity of float 63 is less than the specific gravity for the ink being stored in ink chamber 36.When Float 63 is immersed in the Mo Zhongshi being stored in ink chamber 36, and buoyancy is on float 63.When ink chamber 36 almost by with When ink filling, due to the buoyancy acted on float 63, detection part 59 pivots counterclockwise in Fig. 6.The one of detection part 59 Part is located in the inner space of test section 62 and the wall of contact detecting 62, restriction test section 62 front end, so that inspection Component 59 is surveyed not pivot in the counterclockwise direction further.When detection part 59 in this position when, detection part 59 should Part is blocked in right direction 55 and left direction 56 through test section 62, sensor 103 light.More specifically, because The part of detection part 59 stops light, so when the light emitted from the light emitting portion of sensor 103 reaches the right side of test section 62 When a face in face and the left side, another face in the right and left of test section 62 and sensor 103 is reached The intensity of light of light receiver become smaller than threshold value, such as zero.The part of detection part 59 fully can prevent light from existing It, can be with partly absorbing light by there in right direction 55 and left direction 56, thus it is possible to vary the path of light or fully Reflected light.

When ink is consumed from ink chamber 36, the black surface in ink chamber 36 is reduced and the top of float 63 is by from ink Surface exposure.When black surface further decreases, float 63 follows the black surface of reduction to move down.When it happens, it detects Component 59 pivots clockwise in Fig. 6, and part in the inner space of test section 62 of detection part 59 removes The optical path extended between the light emitting portion of sensor 103 and light receiver.When it happens, the light of sensor 103 no longer by The part of detection part 59 stops, and the intensity of the light received by the light receiver of sensor 103 becomes larger than or waits In threshold value.

With reference to Fig. 5, from locking surface 151 (more specifically, locking surface 151 in direction of insertion 51 (forward direction 57) Forefront) to front 140 (more specifically, forefront of front 140) distance D1 be greater than remove direction 52 (rearward To on 58) from locking surface 151 (more specifically, rearmost part of locking surface 151) to below 41 (more specifically, below 41 The rearmost part of top 41U) distance D2.Distance D1 is less than in direction of insertion 51 (forward direction 57) from operation surface 92 (more Specifically, operate surface 92 forefront) arrive front 140 (more specifically, forefront of front 140) distance D3.Downward From top 41U (more specifically, lowest part of top 41U) to following 42 (more specifically, following 42 topmost) on direction 53 Distance D4 be greater than in downward direction 53 from lower part 41L (more specifically, lowest part of lower part 41L) to following 42 (more specifically Ground, below 42 topmost) distance D5.In this embodiment, distance D5 is zero.In 51 (forward direction of direction of insertion 57) from top 41U (more specifically, forefront of top 41U) to front 140 (more specifically, forefront of front 140) on Distance D6 be greater than in direction of insertion 51 (forward direction 57) from lower part 41L (more specifically, forefront of lower part 41L) before The distance D7 in face 140 (more specifically, forefront of front 140).Lower part 41L includes being located at sealing in downward direction 53 Part between the central axis 72 and following 42 of the ink supply opening 71 of part 76.Ink supply opening 71 central axis 72 with The central crossbar of ink supply opening 71, and run through the direction of seal member 76 in ink supply opening 71, that is, in this implementation Extend in forward direction 57 and backward directions 58 in example.The center of ink supply opening 71 is at least one of ink supply opening 71 Point center, and when black supply pipe 102 by ink supply opening 71 be inserted into when, limit ink supply opening 71 it is described at least The inner surface of the seal member 76 of a part contacts the outer surface of black supply pipe 102.For example, if limiting ink supply opening 71 The inner surface of seal member 76 has the first inner surface and the second inner surface, and the first inner surface contacts black supply pipe 102 Outer surface, and the second inner surface does not contact the outer surface of black supply pipe 102, then the center of ink supply opening 71 is ink supply opening 71, the center of part that is limited by the first inner surface rather than by the second inner surface.If whole inner surfaces of seal member 76 The outer surface of black supply pipe 102 is contacted, then the center of ink supply opening 71 is the center of entire ink supply opening 71.

With reference to Fig. 6, before print cartridge 30 is inserted into box mounting portion 110, valve 77 closes ink supply opening 71.Mo Congmo chamber Room 36 is blocked to the flowing of the outside of print cartridge 30.

With reference to Fig. 7, print cartridge 30 is inserted into shell 101 via the opening 112 of box mounting portion 110.41 behind rear cover 31 Top 41U ratio below 41 lower part 41L position more backward, that is, than below 41 lower part 41L be positioned in backward directions 58 Far.Therefore, compared with lower part 41L is away from user's positioning, top 41U is positioned closer to user, and user is intended in promotion Print cartridge 30 to be inserted into box mounting portion 110 by portion 41U in direction of insertion 51.Moreover, because top 41U includes that instruction should push away The letter or symbol of dynamic top 41U, so user is prompted to push top 41U.The lower part of front cover 32 is located at the lower part of shell 101 Guiding groove 109 in.More specifically, the second protrusion 86, limit recess portion 87 and be more than front cover 32 below 142 ground prolong The groove bottom wall for the part contact guidance groove 109 stretched, and below front cover 32 142 rear portion also contact guidance groove 109 Groove bottom wall.Therefore, the front of front cover 32 is slightly increased.

With reference to Fig. 8, when print cartridge 30 is further inserted into box mounting portion 110, sliding block 107 enters recess portion 87 and connects Touch the second protrusion 86 of print cartridge 30.Because user pushes behind print cartridge 30 41 top 41U, print cartridge 30 is wound on sliding block 107 and the second contact point between protrusion 86 pivot counterclockwise in fig. 8.When it happens, below front cover 32 142 be moved away from it is outer The groove bottom wall of the guiding groove 109 of the lower part of shell 101, and the top of print cartridge 30 is drawn closer to the top of shell 101 109 ground of guide groove is mobile.

With reference to Fig. 9, when print cartridge 30 with resisting the pushing force for the extension spring 114 that sliding block 107 is pushed on removing direction 52 By further when being inserted into direction of insertion 51, the cap 79 of black supply department 34 initially enters guide portion 105, and bar 125 starts Into recess portion 96.

With reference to Figure 10, when print cartridge 30 with resisting the pushing force for the extension spring 114 that sliding block 107 is pushed on removing direction 52 By further when being inserted into direction of insertion 51, black supply pipe 102 enters ink supply opening 71 and resists helical spring 78 It leaves to pushing force 76 ground of seal member and pushes valve 77.The pushing force of extension spring 114 by remove direction 52 on via sliding block 107 are applied to print cartridge 30, and the pushing force of helical spring 78 is applied to print cartridge 30 on removing direction 52.

Bar 125 in recess portion 96 supports front cover 32 from below.IC plate 64 reaches the position of 106 lower section of contact, and makes While being resiliently deformed in upward direction 54, electrode 65 contacts corresponding contact 106 respectively for contact 106.When it happens, The contact 106 that IC plate 64 is elastically deformed 53 in downward direction on push, but IC plate 64 is supported from below by bar 125.Therefore, Electrode 65 is accurately located in upward direction 54 and in downward direction 53 relative to contact 106.But bar 125 still may not be used Certain support front cover 32.

With reference to Figure 10, the protrusion 43 of rear cover 31 reaches sticking department 145, and inclined surface 155 and horizontal surface 154 exist It is slided on sticking department 145.Although because user pushes next 41 top 41U in direction of insertion 51 anticlockwise moment quilt It is applied to print cartridge 30, but the sliding contact between inclined surface 155 and sticking department 145 causes print cartridge 30 around pivoting centre O It pivots clockwise, pivoting centre O is the center that the ink supply opening 71 of black supply pipe 102 is inserted by it, that is, ink supply The center of a part of pipe 102, part contact limit the inner surface of the seal member 76 of ink supply opening 71.Ink in Figure 10 The posture of box 30 is the example of the second posture.When print cartridge 30 is in the second posture, as shown in Figure 10, locking surface 151 Than sticking department 145 53 in downward direction on be positioned to it is remote.As shown in Figure 10, when print cartridge 30 is in the second posture, locking Surface 151 can also be positioned on removing direction 52 (backward directions 58) remote than sticking department 145.

When print cartridge 30 is in the second posture, the locking surface 151 of protrusion 43 is located at 145 lower section of sticking department, that is, than lock Determine portion 145 53 in downward direction on be positioned to it is remote.When print cartridge 30 is in the second posture, along direction of insertion 51 and direction is removed The position of 52, pivoting centre O and the position of electrode 65 are at least partly overlapped.Therefore, by pushing down on electrode 65 and being applied It is zero or very small for being added to the size for the torque that the pushing force of the contact 106 of print cartridge 30 generates.When print cartridge 30 is in the second posture When middle, below rear cover 31 42 contact shells 101 lower part guiding groove 109 groove bottom wall or closer to shell 101 Lower part guiding groove 109 groove bottom wall positioning.In this embodiment, when print cartridge 30 is in the second posture, below 42 extend in a horizontal plane.When print cartridge 30 is in the second posture, behind 41 lower part 41L ratio below 41 top 41U more To prelocalization, that is, be positioned in direction of insertion 51 than top 41U remote.

With reference to Figure 11, when print cartridge 30 resists the pushing force for the extension spring 114 for pushing sliding block 107 on removing direction 52 simultaneously And resist helical spring 78 pushing force by further when being inserted into direction of insertion 51, inclined surface 155 and horizontal surface 154 are positioned in direction of insertion 51 far than sticking department 145.Because by pushed in direction of insertion 51 next 41 top 41U The anticlockwise moment that generates of user be applied to print cartridge 30, so when inclined surface 155 and horizontal surface 154 do not contact locking When portion 145, print cartridge 30 pivots counterclockwise around pivoting centre O, and pivoting centre O is the ink supply that black supply pipe 102 is inserted by it The center of opening 71.

When print cartridge 30 pivots counterclockwise, wherein locking surface 151 and sticking department 145 are being inserted into the arrival of locking surface 151 Position facing with each other on direction 51 and removal direction 52.Moreover, rear cover 31 contacts sticking department when print cartridge 30 pivots counterclockwise 145.When it happens, the impact of contact informs that the insertion of user's print cartridge 30 is completed.When user stops pushing print cartridge 30, print cartridge 30 are moved up by the pushing force of extension spring 114 and the pushing force of helical spring 78 that apply via sliding block 107 in removal direction 52 It is dynamic.When it happens, as shown in Figure 11, locking surface 151 contacts sticking department 145, and print cartridge on removing direction 52 30 movement on removing direction 52 relative to box mounting portion 110 is limited.The posture of print cartridge 30 in Figure 11 is the first posture Example.So complete the installation that print cartridge 30 arrives box mounting portion 110.It is resisted on removing direction 52 in locking surface 151 The pushing force of extension spring 114 and the pushing force of helical spring 78 the case where contacting sticking department 145 on removing direction 52 Under, print cartridge 30 is locked or is maintained in box mounting portion 110.

In the following paragraphs, print cartridge 30 is described more fully from the second posture to the pivot movement of the first posture.

With reference to Figure 12, meet the following conditions:

FH>GL。

G is the size of the gravity acted on print cartridge 30.F be when print cartridge 30 is in the first posture remove direction 52 on Push the size of the extension spring 114 of print cartridge 30 and the pushing force of helical spring 78.L is the edge when print cartridge 30 is in the second posture Distance of the direction of insertion 51 between the center of gravity M and pivoting centre O of print cartridge 30.H be when print cartridge 30 is in the second posture after The lower end of the top 41U in face 41 from pivoting centre O along the height of the upward direction 54 vertical with direction of insertion 51.

When print cartridge 30 is inserted into box mounting portion 110 by user, user, which needs to be greater than using its size U, is removing direction The power of the size F of pushing force on 52 pushes print cartridge 30 in direction of insertion 51.In other words, it needs to meet the following conditions: F < U. Figure 12 diagram is the print cartridge 30 when pushing dynamic print cartridge 30 of F using its size as user, and F is as being inserted into threshold required by print cartridge 30 It is worth size.Moreover, user pushes below 41 top 41U, that is, push the part above the lower end of top 41U.Therefore, work as ink When box 30 is inserted into box mounting portion 110, power is applied to above the lower end of top 41U of print cartridge 30 in direction of insertion 51 Part, the size U of the power are greater than the size F of pushing force.Because top 41U is approximately perpendicular to when print cartridge 30 is in the second posture Direction of insertion 51, so anticlockwise moment is applied to print cartridge 30, the size of the anticlockwise moment is at least more than product FH.Figure 12 Diagram is when it is behind H 41 lower end of top 41U along the height of upward direction 54 from pivoting centre O that user, which pushes it, Print cartridge 30.On the other hand, print cartridge is applied to by the clockwise moment that gravity generates, the size of the clockwise moment is to multiply Product GL.

Because meeting above-mentioned condition FH > GL, when print cartridge 30 is inserted into box mounting portion 110, it is applied to print cartridge 30 Resultant couple be directed toward counterclockwise.Therefore, completed on sticking department 145 when inclined surface 155 and horizontal surface 154 sliding and When separating in direction of insertion 51 with sticking department 145, anticlockwise moment causes print cartridge 30 to be pivoted to the first posture from the second posture.

The ink amount that the size G of the gravity acted on print cartridge 30 is depended on being stored in print cartridge 30 changes.But if work as The new print cartridge 30 of ink with primary quantity meets condition FH > GL when being inserted into, then relatively low has used print cartridge 30 when its ink is measured Also meet the condition when being inserted into.This is because reducing with inking amount and product GL becomes smaller, and product FH is constant.Change speech It, size G is at least when ink chamber 36 is fully filled by the ink of primary quantity or when the ink in ink chamber 36 is consumed Act on the size of the gravity on print cartridge 30.

Moreover, because the second protrusion 86 of print cartridge 30 receives extension spring 114 via the sliding block 107 below pivoting centre O Pushing force, so the pushing force of extension spring 114 also generates the additional torque for causing print cartridge 30 to pivot counterclockwise.But Even if the torque generated by extension spring 114 is not applied to print cartridge 30, the resultant couple for being applied to print cartridge 30 still will the inverse time Needle is directed toward.

With reference to Figure 14, when print cartridge 30 is in the first posture, the upper end of locking surface 151 is located at the outside of imaginary circles C, and And the lower end of locking surface 151 is located in imaginary circles C.Imaginary circles C is at pivoting centre O with its center and and sticking department 145 intersect.Therefore, when locking surface 151 contact sticking department 145 while pushing force by remove direction 52 on be applied to ink When box 30, sticking department 145 slides on locking surface 151 towards the lower end of locking surface 151.That is, when sticking department 145 and locking When surface 151 contacts, print cartridge 30 further pivots counterclockwise.

With reference to Figure 13, when print cartridge 30 is inserted into box mounting portion 110 by user, user can substitute next 41 top Push to 41U next 41 lower part 41L.But because meeting the following conditions, print cartridge 30 can in Figure 13 pivot counterclockwise Turn:

(Fcosα)N>GL。

Lower part 41L is the plane intersected with the angle of α degree with the first imaginary plane P 1 when print cartridge 30 is in the second posture, And the first imaginary plane P 1 is perpendicularly to the insertion direction 51.N is the vertical line that the second imaginary plane P 2 is extended to from pivoting centre O Length, the second imaginary plane P 2 is vertical with lower part 41L and intersects with the lower end of lower part 41L.

When the power for the size F that user is greater than pushing force using its size pushes lower part 41L in direction of insertion 51, the inverse time Needle force square is applied to print cartridge 30, and the size of the anticlockwise moment is at least more than product (Fcos α) N.Because meeting above-mentioned condition (Fcos α) N > GL, so even if being applied to the resultant couple of print cartridge 30 still when user pushes lower part 41L in direction of insertion 51 So it is directed toward counterclockwise.

When user wishes to remove print cartridge 30 from box mounting portion 110, user pushes down on operation surface 92.With reference to Figure 15 A And 15B, when print cartridge 30 is in the first posture, operation surface 92 is observable when observing print cartridge 30 in downward direction 53 And when in forward direction 57 (direction of insertion 51) observe print cartridge 30 when be observable.In other words, when print cartridge 30 is When in one posture, operation surface 92 is towards upward direction 54 and backward directions 58 (removing direction 52).Therefore, when user works as print cartridge 30 in the first posture when pushing operation surface 92 to discharge print cartridge 30, the power of user is towards in downward direction 53 and forwards It is directed toward to 57 (direction of insertion 51).Due to the power being directed toward towards forward direction 57 (direction of insertion 51), locking surface 151 and locking Portion 145 separates.Due to the power being directed toward towards in downward direction 53, print cartridge 30 is pivoted to the second posture from the first posture.Therefore, with Wherein the case where print cartridge 30 is pivoted to the second posture from the first posture to locking surface 151 while sliding on sticking department 145 Compare, being applied to operation surface 92 to cause print cartridge 30 to be pivoted to power required for the second posture from the first posture becomes smaller, And user can be easy release print cartridge 30.

When print cartridge 30 is pivoted to the second posture from the first posture, locking surface 151 is located at 145 lower section of sticking department, that is, ratio Sticking department 145 53 in downward direction on be positioned to it is remote.Extension spring 114 and the pushing force of helical spring 78 are removing direction 52 Upper mobile print cartridge 30.When print cartridge 30 is separated with sliding block 107, pushing force is no longer applied to print cartridge 30, and print cartridge 30 stops It is moved on removing direction 52.When it happens, the rear cover 31 of at least print cartridge 30 is located at the outside of shell 101, and user can be from Box mounting portion 110 takes out print cartridge 30.

According to above-described embodiment because when print cartridge 30 is inserted into box mounting portion 110 behind rear cover 31 41 lower part Top 41U of the 41L than behind rear cover 31 41 is positioned to far in direction of insertion 51, thus user be intended to push closer to The top 41U of user's positioning, and be not intended to push lower part 41L.When top 41U is pushed, torque is applied to box peace Print cartridge 30 in dress portion 110, so that print cartridge 30 is pivoted to the first posture from the second posture around pivoting centre.In the first posture The locking surface 151 of print cartridge 30 remove direction 52 on contact sticking department 145, and print cartridge 30 remove direction 52 on relative to The movement of box mounting portion 110 is limited, that is, print cartridge 30 is locked in box mounting portion 110.User can be easy in box mounting portion It is inserted into 110 and locks print cartridge 30.

Because next 41 top 41U includes the letter or symbol that instruction should push top 41U, user is prompted to Push top 41U.

Because meeting condition FH > GL, by being generated by behind pushing 41 top 41U and causing print cartridge 30 from the The torque that two postures are pivoted to the first posture become larger than generated by the gravity that acts on print cartridge 30 and cause print cartridge 30 from First posture is pivoted to the torque of the second posture.

Because meeting condition (Fcos α) N > GL, even if 41 lower part 41L is pushed below, behind being pushed 41 lower part 41L is generated and the torque for causing print cartridge 30 to be pivoted to the first posture from the second posture still becomes larger than by acting on In the torque that the gravity on print cartridge 30 generates and print cartridge 30 is caused to be pivoted to from the first posture the second posture.

Because when print cartridge 30 in the second position when the second protrusion 86 than black supply department 34 53 in downward direction on be positioned to Far, and the second protrusion 86 via sliding block 107 from extension spring 114 receive pushing force, so additional torque is applied to ink Box 30 is pivoted to the first posture from the second posture so as to cause print cartridge 30.

Because the position of pivoting centre O and the position of electrode 65 are along direction of insertion 51 when print cartridge 30 is in the second posture At least partly be overlapped, thus by contact 106 pushing force generate and be applied to print cartridge 30 torque size be zero or It is very small.

It is positioned than locking surface 151 further from pivoting centre O because operating surface 92, user easy to operate can grasp Make surface 92 to cause print cartridge 30 to be pivoted to the second posture from the first posture.

Because operating surface 92 when print cartridge 30 is in the first posture towards upward direction 54 and removing direction 52, work as When user's operation operates surface 92 to discharge print cartridge 30 from the first posture, the power of user is towards in downward direction 53 and direction of insertion 51 It is directed toward.Due to the power being directed toward towards direction of insertion 51, locking surface 151 is separated with sticking department 145.Due to towards in downward direction 53 power being directed toward, print cartridge 30 are pivoted to the second posture from the first posture.Therefore, and wherein in locking surface 151 in sticking department 145 The case where print cartridge 30 is pivoted to the second posture from the first posture while upper sliding is compared, and is applied to operation surface 92 to cause ink Box 30, which is pivoted to power required for the second posture from the first posture, becomes smaller, and user can be easy release print cartridge 30.

Because the upper end of locking surface 151 is located at outside and the locking of imaginary circles C when print cartridge 30 is in the first posture The lower end on surface 151 is located in imaginary circles C, so when pushing force is applied to print cartridge 30 on removing direction 52, sticking department 145 slide on locking surface 151 towards the lower end of locking surface 151.

Because operate surface 92 along direction of insertion 51 position and it is secondary above 91 along direction of insertion 51 position at least Partly be overlapped, or operation surface 92 and it is secondary above 91 53 in downward direction on be at least partly overlapped, and in operation table Space is formed between 91 above face 92 and pair, so operation surface 92 becomes to can recognize user.

Because at least part for operating surface 92 is far more prominent in upward direction 54 than locking surface 151, i.e., Make when print cartridge 30 falls in the case where above 39,141 towards in downward direction 53, locking surface 151 still can be operated At least part on surface 92 is protected and can not be damaged.

In the above-described embodiments, 41 top 41U and lower part 41L is continuous behind.41 top 41U behind but It still can be not necessarily with lower part 41L continuous.For example, in another embodiment, behind 41 may include in top 41U and The part extended in forward direction 57 or backward directions 58 between the 41L of lower part.Moreover, in top 41U and lower part 41L Each can be not necessarily plane, that is, flat surfaces, but can be curved surface or ball table in another embodiment Face.
