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 extend Part contact guidance groove 109 groove bottom wall, 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 contacts 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 pivots counterclockwise in fig. 8.When it happens, 142 shell is moved away from below front cover 32 The groove bottom wall of the guiding groove 109 of 101 lower part, and the top of print cartridge 30 is closer to the guidance on the top of shell 101 109 ground of 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 are being locked Determine to slide in portion 145.Although because user pushes next 41 top 41U in direction of insertion 51 anticlockwise moment is applied It is added to print cartridge 30, but the sliding contact between inclined surface 155 and sticking department 145 causes print cartridge 30 suitable around pivoting centre O Hour hands pivot, and pivoting centre O is the center that the ink supply opening 71 of black supply pipe 102 is inserted by it, that is, black supply pipe The center of 102 a part, part contact limit the inner surface of the seal member 76 of ink supply opening 71.Print cartridge in Figure 10 30 posture is the example of the second posture.When print cartridge 30 is in the second posture, as shown in Figure 10, locking surface 151 compares 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 list Face 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 locking 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 in the case where contacting sticking department 145 on removing direction 52, 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 52 On the power of size F of pushing force print cartridge 30 is pushed in direction of insertion 51.In other words, it needs to meet the following conditions: F < U.Figure 12 diagrams are 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 value required by print cartridge 30 Size.Moreover, user pushes below 41 top 41U, that is, push the part above the lower end of top 41U.Therefore, work as print cartridge 30 when being inserted into box mounting portion 110, and power is applied to the portion above the lower end of the top 41U of print cartridge 30 in direction of insertion 51 Point, the size U of the power is greater than the size F of pushing force.Because top 41U is approximately perpendicular to slotting when print cartridge 30 is in the second posture Enter direction 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 figure Show 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 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 It and is observable when observing print cartridge 30 in forward direction 57 (direction of insertion 51).In other words, when print cartridge 30 is first When in posture, operation surface 92 is towards upward direction 54 and backward directions 58 (removing direction 52).Therefore, when user works as print cartridge 30 When pushing operation surface 92 when in the first posture to discharge print cartridge 30, the power of user is towards in downward direction 53 and forward direction 57 (direction of insertion 51) is directed toward.Due to the power being directed toward towards forward direction 57 (direction of insertion 51), locking surface 151 and sticking department 145 separation.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, and wherein Compare the case where print cartridge 30 is pivoted to the second posture from the first posture while sliding on sticking department 145 in locking surface 151, Being applied to operation surface 92 becomes smaller to cause print cartridge 30 to be pivoted to power required for the second posture from the first posture, and uses Family can be easy release print cartridge 30.

When print cartridge 30 is in the first posture, below 142 and following 42 than pivoting centre O remove direction 52 on be positioned to Far, and following 42 are positioned to remote on removing direction 52 than following 142 and are positioned in upward direction 54 than following 142 Far.Moreover, following 142 extend on removing direction 52, and following 42 extend on removing direction 52 and upward direction 54.When When print cartridge 30 is in the first posture, between below 142 and the groove bottom wall of guiding groove 109 and below 42 and guide groove Gap is formed between the groove bottom wall of slot 109.With reference to Figure 11, from following 142 (more specifically, following 142 in downward direction 53 Topmost) to guiding groove 109 groove bottom wall distance D11 be less than in downward direction 53 from following 42 (more specifically, 42 topmost below) to guiding groove groove bottom wall distance D12.With reference to Figure 14, below 42 and the formation of imaginary plane P 3 The angle of β degree therebetween.Imaginary plane P 3 extends and from following 142 perpendicular to 53 He in downward direction on removing direction 52 Upward direction 54.Print cartridge 30 is pivoted between the first posture and the second posture with the angle of γ degree.The angle of β degree is greater than γ degree Angle.

Because distance D12 is greater than the angle of γ degree greater than the angle of distance D11 and β degree, work as print cartridge 30 from first When posture is pivoted to the second posture, 142 rearmost part becomes the lowest part of all parts of print cartridge 30 below front cover 32.If 42 and following 142 extend in the same plane below, then when print cartridge 30 is pivoted to the second posture from the first posture, below 42 Rearmost part will become the lowest part of all parts of print cartridge 30.Therefore, because following 42 rearmost part is than following 142 further from pivot Turn center O positioning, thus following 42 rearmost part by the rearmost part than following 142 53 in downward direction on be positioned to it is remote.However, In this embodiment, because when print cartridge 30 is pivoted to the second posture from the first posture, below 142 rearmost part become print cartridge The lowest part of 30 all parts, so the gap between print cartridge 30 and the groove bottom wall of guiding groove 109 becomes relatively small, The gap is needed in order to make print cartridge 30 be pivoted to the second posture from the first posture.Incidentally, in this embodiment, work as ink When box 30 is in the second posture, 142 rearmost part is such as below, and entire following 42 also become all parts of print cartridge 30 most Lower part.That is, when print cartridge 30 is in the second posture, below 42 extend in a horizontal plane.

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 on removing direction 52 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 at It removes and is moved on 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, user can be easy that print cartridge 30 is inserted into and locked in box mounting portion 110, and can It is easy the print cartridge 30 that release locks in box mounting portion 110.

When print cartridge 30 is pivoted to the second posture from the first posture because following 42 than following 142 further from pivoting centre O Positioning, so following 42 is much more mobile in downward direction 53 than following 142.But because when print cartridge 30 is in the first posture When, below 42 be positioned in upward direction 54 than following 142 it is remote, so the groove bottom wall of following 42 contact guidance groove 109 And following 42 reduction a possibility that moving down is hindered by the contact.

Because when print cartridge is in the first posture, between below 142 and the groove bottom wall of guiding groove 109 and under Gap is formed between face 42 and the groove bottom wall of guiding groove 109, so the groove bottom wall of following 42 contact guidance groove 109 is simultaneously And further decreasing a possibility that moving down by the contact obstruction following 42.

When print cartridge 30 is pivoted to the second posture from the first posture because following 142 than following 42 closer to pivoting centre O Positioning, so following 142 is more mobile less in downward direction 53 than following 42.Therefore, although following 142 on removing direction 52 Extend, but the groove bottom wall of following 142 contact guidance groove 109 and by the contact hinder following 142 to moving down A possibility that dynamic, reduces.On the other hand, because following 142 extend on removing direction 52, above 141 and following There are big distances between 142.Therefore, the capacity of print cartridge 36 can be made bigger.

Because 142 extend on removing direction 52 below front cover 32, it is possible to it is easy to injection-molded front cover 32, because It can be easy to remove mold from front cover 32.
