And the terminal mechanism (not shown) of terminal arrangement part 50 is connected electrically on the splicing ear 37a of circuit board 37, and wherein said circuit board 37 is located in the substrate pockets 46 of print cartridge 14.Like this, in the data such as ink kind, ink surplus, lot number and valid expiration date of being stored in the semiconductor storage of printer 11 institute's actual installation on can obtaining circuit board 37, can also carry out the rewriting of data.

Below, describe from the structure that flow of print cartridge 14 suppressing with the ink of the coupling part leakage of coupling part 49.

When print cartridge 14 was extracted from coupling part 49, the surface of the ink feed pin 71 that exposes was soaked by ink, perhaps has small volume of ink to splash in the transition period of extracting, thereby produced ink leakage.If the user carries out extracting and installing of print cartridge 14 repeatedly more than common number of times ground, then as mentioned above, the quantity of ink that leaks can be detained to flowable degree, thereby, described ink flows through the gap portion of housing body part 32 with the mating part of lid housing 33 with capillarity, and flow to the place of isolation from described support section 43.

As mentioned above, as Fig. 2, Fig. 3 and shown in Figure 4, for described housing body part 32, the above-below direction of establishing each figure is the depth direction of housing.Lid housing 33 coincide with it with the state that cooperates with described housing body part 32, thereby forms container casing 31.Just, as Fig. 2 (A) along the Fig. 2 (B) of (B)-(B) analyse and observe and Fig. 2 (A) along (C)-Fig. 2 (C) of (C) analysing and observe shown in, the sidewall paneling 32b of housing body part 32 is provided with the end face 32c as a composition surface.And, be provided with lower surface 33c at the peripheral part of plate portion 33a of lid housing 33 as another composition surface.

Then, the medial surface 32d of described sidewall paneling 32b is slidably engaged face as one, the lateral surface 45e of inside casing part 45 is slidably engaged face as another, and wherein this inside casing part 45 is to form along near the state that erects the neighboring of covering housing 33.

As shown in Figure 2, the mating part that lid housing 33 cooperates with respect to housing body part 32 is made of the contact mating part 27 and the part 28 that is slidingly matched.Just, contact mating part 27 is so that the above-mentioned end face 32c of housing body part 32 1 sides and the above-mentioned lower surface 33c that covers housing 33 1 sides carry out the relation that face contacts forms.On the other hand, on one side the part 28 that is slidingly matched is to slide with the above-mentioned lateral surface 45e of the inside casing part 45 of lid housing 33 1 sides and the above-mentioned medial surface 32d of the sidewall paneling 32b of housing body part 32 1 sides, form Yi Bian carry out the relation that face contacts.

As mentioned above, the matching relationship of housing body part 32 and lid housing 33 is that composite construction by the described relative engagement part 27 and the part 28 that is slidingly matched forms.

Though the described contact mating part 27 and the part 28 that is slidingly matched look like appearance very close to each other in appearance, but, owing on each surface of end face 32c, lower surface 33c, medial surface 32d, lateral surface 45e, have small concavo-convex, so, contact position at each face, part is contacted place, is in the place of gap state in addition in addition.Therefore,, can produce the capillarity of ink, flow thereby produce ink as described above in the place of this gap state.

Flow in order to suppress above-mentioned ink, on the position of leaving described support section 43, form the gap bigger space segment 29 of gap than the described contact mating part 27 and the part 28 that is slidingly matched, and the ink that will flow through described each mating part 27,28 is stored in the described space segment 29, flows thereby suppress ink in space segment 29.

End at the front surface 32a of said vesse housing 31, the angle part (the crest line part of angle part) that forms of the horizontal side 31a that is connected with it of front surface 32a just, and be arranged between the support section 43 of the nearest part in above-mentioned end, be formed with the space segment 29 shown in Fig. 8 (B).The space segment 29 that is positioned at this place constitutes under the continuum of states as the space at recessed portion 29a and perforation part 29b, wherein said recessed portion 29a is located on the plate portion 33a as lower surface 33c part, connects part 29b and be to shear inside casing part 45 and form.By such recessed portion 29a and the profile status that connects the space segment 29 that part 29b forms shown in Figure 10 (B).If the depth direction of above-mentioned recessed portion 29a is the opposite direction of the depth direction of housing body part 32.And, shown in Fig. 8 (C), can also make described perforation part 29b form the run-though space of four quarter window cave shapes.

Shown in Fig. 2, Fig. 8, Figure 10 (B), described space segment 29 is configured near the left and right end portions of front surface 32a of container casing 31.Therefore, for flowing through the ink that comes from contact mating part 27 and the part 28 that is slidingly matched, can be about described suppress it in the space segment 29 at two places and flow, thereby make it can be to horizontal side 31a one side flow of container casing 31.And above-mentioned space segment 29 can only be made of recessed portion 29a, perhaps, also can only constitute by connecting part 29b.

On the other hand, shown in Fig. 2, Fig. 8, Fig. 9, Figure 10 (C), on the position, the left and right sides of each support section 43, dispose space segment 30.The place that is provided with this space segment 30 is exaggerated in Fig. 9 shows, and is to cover the lower surface 33c of housing 33 1 sides and the lateral surface 45e of inside casing part 45.Be formed on the degree of depth on the opposite direction of depth direction that recessed portion 30a on the lower surface 33c has housing body part 32.And, be formed on recessed portion 30b on the lateral surface 45e and have and the depth direction of housing body part 32 degree of depth on the direction of quadrature roughly.Then, two recessed portion 30a and 30b constitute the space that is communicated with.The cut-away section state of described space segment 30 is shown in Figure 10 (C).

Though between adjacent supports part 43, disposed two above-mentioned space segments 30, also can dispose one.When so only disposing one, preferably the spatial volume that will be got by recessed portion 30a, 30b is set greatlyyer.And described space segment 30 can only be made of recessed portion 30a, perhaps, also can only be made of recessed portion 30b.And, also recessed portion 30b can be implemented in the mode of the run-though space of four quarter window cave shapes shown in Fig. 8 (C).

Above-mentioned space segment 29 and 30 gap size are suitably set according to the rerum natura of inks such as the viscosity of ink, surface tension.

In the above-described embodiments,, recessed portion 29a, 30a, 30b etc. cover housing 33 those sides though being formed on,, as shown in figure 13, also they can be formed on housing body part 32 those sides.The identical symbol of mark on the part identical with the example that illustrates previously.

And, shown in Figure 13 (D), on two faces of end face 32c and lower surface 33c, be formed with recessed portion 30c and 29c respectively, can also form a space segment 38 by two recessed portion 30c and 29c.Assign to constitute a space segment by two such recess, this also can similarly implement between the medial surface 32d of the lateral surface 45a of inside casing part 45 and sidewall paneling 32b.

And, needn't worry that at ink ink that this drips or that splash can flow and be attached on the described circuit board 37 when each support section 43 drips or splash.That is, the installation site that is arranged at the circuit board 37 in the described substrate pockets 46 be set identically with the centre line L 1 of support section 43 (ink supply port 42a) or than it more by last, and, be installed on the position with the front surface 32a quadrature of print cartridge 14.Therefore, the ink that drips etc. can not flow to circuit board 37.

And, needn't worry to reclaim that a mouthful 44a drips or when splashing from useless China ink at ink, this drips or the ink that splashes can flow and be attached on the described circuit board 37.That is, the installation site that is arranged at the circuit board 37 in the described substrate pockets 46 is arranged on and is provided with the side that useless China ink reclaims the position opposite of mouthful 44a.Therefore, the ink that drips can not flow to circuit board 37.

If enumerate the action effect that obtains by the foregoing description, it is as follows.

Even the ink that flows out from the place that the ink feed pin 71 of described box mounting portion 13 1 sides and the ink lead-out member 42 of print cartridge 14 1 sides are coincide flows through above-mentioned mating part 27,28 with capillarity, this ink also can be stored in by in the above-mentioned space segment 29,30 that constitutes than the bigger gap, gap that cooperates part 27,28.Even in this stores phenomenon, ink also is capillarity at the gap portion with the spatial volume that has enlarged, and is in the state that is stored in the space segment 29,30.Therefore, the mobile place that is stopped at described space segment 29,30 of the ink in the mating part 27,28, and prevented that ink from flowing to the mating part 27,28 that further extends forward from space segment 29,30.By such inhibition phenomenon, the inkiness of print cartridge 14 can be limited in the minimum zone, but also can prevent that hand is made dirty by ink when loading and unloading print cartridge 14 on box mounting portion 13 liquid flow.

In the end of the front surface 32a of described container casing 31 be present between the support section 43 in the place of approaching described end, be provided with above-mentioned space segment 29, thereby, suppressed ink flowing in described mating part 27,28 in the space segment 29 in the scope of the front surface 32a that is disposed at described container casing 31.Therefore, can prevent that ink from flowing to outside the scope of described front surface 32a, for example flow to the 31a place, horizontal side of container casing 31.
