With reference to the accompanying drawings, various embodiments of the present invention are described.The present invention is applicable to monochrome or color ink-jetting record device, but it is specially adapted to use and has different colours or use color of the same race but have the printer of the different ink materials of different densities (light and shade).The following explanation of doing is that example is carried out with the color printer.

Fig. 2 A, 2B, 2C show the ink cartridge that can be used for color printer that puts forward according to one embodiment of the invention.As shown in the figure, ink cartridge IC includes long (a) 108mm, wide (b) 75mm, the housing 711 of high (c) 22mm.In including, it fills the ink moccasin capsule of making by flexible material (not shown on the figure) of ink.The providing ink part is clogged by a rubber plug (providing ink element) 712.When ink cartridge is inserted into ink cartridge installation site on the primary clustering of pen recorder, the providing ink needle body 714 on the master component will thrust rubber plug 712, so that make the ink in the leather bag offer record-header through feed path.Shown in Fig. 2 C, rubber plug 712 exposes the outer surface at housing 711, if for instance, it is 12.4mm that its center can be positioned at its height (d), is the position of 37mm apart from horizontal lateral distance (e).In the present embodiment, rubber plug 712 leans out about 3mm forward from the front surface of ink cartridge.Like this, even the surface of rubber plug 712 is polluted by ink, also be unlikely to pollute operator's finger.

A garden ring can be set round rubber plug 712, to keep pressure to rubber plug 712.Like this, even when pin is taken out, can prevent that also ink from spilling.This stiffening ring can be disposing with the flat mode of the front surface embedding of housing, its edge can reflexed to the inside.Adopt this structure, between rubber plug 712 and stiffening ring, can form a groove.Therefore, even there is ink to spill, it also can be collected for groove, thereby can prevent leakage.

Shown in Fig. 2 A, be provided with resistor 715 at the top of ink cartridge IC with predetermined resistance.It includes pair of contact, each height (h) 12mm, and wide (i) 6mm, the spacing of contact (j) is 7mm.The distance (g) that its angle is positioned at a side on the ink cartridge end face 901C is 6mm, is the position of 6mm apart from reading end distance from (f).Read assembly 718 on the device can be informed between contact 715a, the 715b of resistor 715 whether set up electrical connection, or the resistance between readout contact.Therefore, whether the information (as color, density, capacity or the like) of ink cartridge or relevant ink has been housed in device, all can have offered pen recorder, so that according to the property driving record-header of ink.

Message elements also can be other form, for example adopt bar code light or magnetic, (electricity can be wiped semiconductor ROM matrix EEPROM to semiconductor devices, or read only memory ROM, the random access memory ram that accumulator is supported), concavo-convex model pattern or the like forms.Utilize predetermined conversion table, can be to employed the ink suitably drive condition or the parameter of setting recording head.

The drive condition of setting comprises driving voltage, pulse width, driving frequency and an emitted dose or the like.Can all select to set to each parameter, also can only select to set wherein a certain, for example only select to set driving voltage, or pulse width, or driving frequency or the like.Can also carry out combination selection to some parameter sets.

Information material on the ink cartridge can provide certain or all conditional parameters for preheating, so that suitably utilize ink with the mode of heating record-header; Can also provide certain or all conditional parameters of relevant ink jet, so that in recording process, obtain best ink jet effect.Under the situation of the multiple ink material that uses different colours, this information material can also comprise that the above-mentioned injection conditions parameter of relevant various ink materials or other have related parameter.

In the bottom side of ink cartridge, and and resistor 715 corresponding positions, shown in Fig. 2 B, be formed with otch partly 716 with predetermined contour structures.Otch partly 716 colors that should be arranged on its ink is on the intrinsic position.By being arranged on the sign element 719 on the master component, can guarantee correctly packing into of ink cartridge.Otch partly 716 can form in following ranges, promptly from a side of ink cartridge towards providing ink partly on 714 the direction, be formed in this example to the scope between the location point before providing ink part 714 apart from the location point of this lateral distance (k) for 9mm, the wide of otch part 716 is 13.5mm, and long is 9mm.Can forming at interval in this scope, (m) is four different otch parts of 2mm.For instance, for the ink cartridge IC(901BK that contains black ink), can be partly at its otch of the position of the most close ink cartridge side formation; The ink cartridge IC(901C of Sheng blue-green ink) otch that is had partly adjoins mutually with the former; Contain the ink cartridge IC(901M of magneta colour ink), the otch that is had partly partly adjoins mutually with the otch that indicates the blue-green ink; And contain the ink cartridge IC(901Y of yellow ink) partly 716 the most close providing inks are partly for the otch that has.On device, dispose corresponding sign element 719, thereby can make each ink cartridge IC be enclosed in right position.

Be used to guarantee that the structure that ink cartridge is enclosed in the tram constitutes, also can comprise a jut that is arranged on the ink cartridge and be arranged on groove on the master component.

With regard to the otch on the ink cartridge partly with regard to, if when device is useful on the cutter that forms the otch part on ink injection device, everything oral area part can utilize this ink injection device to form.Therefore, everything oral area part can form when injecting with providing ink.

In the another one example, otch partly can form before providing ink injects, and on ink-feeding device, be provided with one with the suitable marking device of otch part so that have only the correct ink of color can supply with injection.

If compare with after ink cartridge is filled with ink, forming otch situation partly again, adopt these providing ink method for implanting, the relativeness between otch part and the ink cartridge ink inside color can better be guaranteed.

Ink cartridge can be provided with two guide rails 717, so that with the ink cartridge charging apparatus, and can also gap of formation between bottom surface partly be installed at the distance device.Therefore, even there is ink to bleed, also be difficult to pollute the basal surface of ink cartridge.And, even the bottom surface of device is contaminated, pollutes and also can not expand.

Ink cartridge has excess ink and collects mouthfuls 720, fails the excess ink that is used to write down with collection.This collection mouth can be arranged on partly 712 position of contiguous providing ink.Collected ink is introduced into the excess ink absorber of the ink leather bag below that is arranged in ink cartridge.Between excess ink absorbing material and ink cartridge bottom, can put a plastic resin thin layer.Like this because capillarity between this thin layered element and ink cartridge, with effectively collected excess ink by the outer peripheral areas in the ink cartridge, be diffused in the whole absorbing material.Therefore, with collection mouthful 720 non-conterminous absorbing materials that connect, also can accommodate these inks.

The structure that Fig. 3 A, 3B, 3C show the ink cartridge installation position on the master component of this pen recorder respectively constitutes.At ink cartridge ink cartridge partly is installed and is installed in the passage, a plate 721 and a limit element 722 are arranged.Plate can open and close, and its area equals the cross-sectional area of ink cartridge substantially; Limit element 722 is used for the unlatching of confinement plate 721.Plate 721 is used as protecting component, and when ink cartridge not being installed or changing a plurality of ink cartridge simultaneously, it can prevent that operator's finger is subjected to the injury of ink supply needle 714.

When ink cartridge be unkitted fashionable, as shown in Figure 3A and since the otch of control element 722 partly 723 and the part of plate 721 be meshing with each other, and do not allow plate 721 to be opened.

Plate 721 has rectangular profile, and can rotate around pivot 724.In its rotating range, plate 721 should be an element that can not produce any interference, and promptly it can not contact with ink supply needle 714 or resistance detection element 718.In order to realize this point, can cut a certain of plate or some part, in order to avoid produce disadvantageous influencing each other.By excising its a part of method by this way, the setting of pivot 724, ink supply needle 714 and sensing element 718, what can be provided with is more close each other, and then can reduce device size.In the present embodiment, shown in Fig. 3 B,, just be formed with otch partly 725 and 726 for fear of producing mutual interference mutually between plate 721 and the ink supply needle 714 and between plate 721 and resistance detection element 718.For stoping opening of plate 721, above plate 721, be provided with two limit elements 722.Each limit element 722 all has tapered part 728, and this part 728 can contact with the upper limb part 901b of ink cartridge at its front surface 901a place.Insertion by ink cartridge IC is moved, and it can be around its pivot 727 to inner rotary.The inclination of its relative vertical direction is approximately 45 ° of (θ ₁).In the present embodiment, the inclination of tapered face 728 relative direction of insertion is approximately 30 ° of (θ ₂).The typical angle of these of limit element 722 is considerable to the level and smooth insertion of finishing ink cartridge.In order the thrust of ink cartridge to be converted to the power of direction (outwardly) promotion limit element 722 as shown by arrow E, must have angle θ ₁But the size of this angle can be arbitrarily, as long as it can outwards promote limit element 722 for enough vector component power.If this angle is not less than about 45 °, then when for inserting the very little power of ink cartridge effect to ink cartridge the time, just sure limit element 722 is outwards pushed open.

Be formed on the angle θ of the tapered part 728 of limit element 722 ₂, can be effectively and angle θ ₁Cooperation is converted to outside acting force to limit element 722 with the insertion force with ink cartridge.Angle θ ₂Size also can be arbitrarily, as long as can realize above-mentioned and angle θ ₁The purpose of cooperation gets final product.But, θ ₂In fact should not be preferably about 30 ° greater than 45 °.

Shown in Fig. 3 B, the angle θ of limit element 722 ₁Can utilize retainer 729 to regulate.Limit element 722 is pushed away by sheet spring 730 usually, is return with convenient ink cartridge, can suitably limit plate 721.

Limit element 722 with above-mentioned each angle is herringbone structure and constitutes.When inserting ink cartridge, the front part 901b of ink cartridge will contact with limit element 722.Along with the further insertion of ink cartridge, two limit elements 722 will be substantially simultaneously around separately pivot 727 to inner rotary, thereby plate 721 is discharged by restriction state.

Limiting element 722 preferably is configured on such position, and promptly it can not contact with the resistance 715 on the ink cartridge end face 901C.

Limit element 722 its otch partly before and afterwards each partly have substantially the same length.As shown in Figure 3A, when ink cartridge is positioned at position shown in (4), the front side of limit element 722 partly 722a will contact with an edge 901b of ink cartridge, and after this, when ink cartridge further inserts forward, will promote limit element 722 simultaneously.Preferably when limit element 722 is lifted fully (shown in (5) among the figure), its rear portion is 722b release board 721 partly.By utilizing a kind of like this position relation, after limit element 722 complete release boards 721, the front surface 901a of ink cartridge realizes contacting with plate 721 in the position shown in (6).Then, the locking of plate 721 has just been removed smoothly.Position deviation (p) between position (5) and position (6) can be very little, in this example, though it is limited, also is about 2～3mm.

When ink cartridge is opened along with passage and when further inserting, the providing ink of ink cartridge outlet 712 will be connected with the providing ink assembly 714 on the master component of pen recorder, thereby can be with providing ink to record-header.

Shown in Fig. 3 A and 3B, the periphery of the providing ink assembly 714 in the master component has a jut 719, and the latter can partly 716 be meshed with the otch that had on the ink cartridge, to prevent wrong plug.It also has a sensing element 718 that is used to read resistance, so that whether ink cartridge has been housed in the identification device.

The notch portion 716, providing ink that prevents sign element 719, providing ink coupling assembling 714 and read assembly 718 and ink cartridge that mistake is packed into partly 712 and 715 of resistors, preferably have following mutual alignment relation: promptly the direction of inserting at ink cartridge arrives otch partly 716 and indicate the engagement reference position (1) of 719 of elements successively by following order, connection reference position (2) between providing ink part 712 and the providing ink coupling assembling 714, the contact reference position (3) between resistor and the read assembly 718.According to this mutual alignment relation, when the operator inserted ink cartridge IC, (1) located (referring to Fig. 3 A) in the position, began contact or claimed engagement between the otch part 716 of ink cartridge front surface 901a and the sign element 719.It is in its certain intrinsic position that above-mentioned otch partly is arranged on corresponding to ink color.Then, can differentiate just whether this ink cartridge is the proper position that is enclosed in it.Because at the otch of ink cartridge partly 716 and can partly have only the structural relation of certain simple combination between 716 juts that are meshed 719 with otch, if then ink cartridge is encased in wrong position, after it props up jut 719, can not further be inserted into.Have only after meshing relation formation therebetween, ink cartridge could further be inserted.When carrying out the colour record with pen recorder, this point is effective especially.When carrying out the colour record, each record-header corresponds respectively to different separately colors.Be used in providing ink partly 712 be communicated with before, differentiate earlier whether ink cartridge is encased in the method for tram, can prevent from not wish the ink mixing phenomena that takes place in advance.

When otch part 716 was meshed with sign element 719, the ink coupling assembling 714 in the master component and the providing ink of ink cartridge partly could form connection between 712, made that (2) are located just to allow to supply with ink by ink cartridge in the position.After finishing this work,, the ink in ink supply needle 714 and the ink cartridge is communicated with along with further insertion ink cartridge.In this example, the outstanding forward about 12mm of ink supply needle 714 indicates the outstanding forward about 10mm of element 719.Yet, because the providing ink in the ink cartridge partly is arranged on the position g apart from front surface 901a() and about 3mm distant place, therefore, even ink supply needle 714 is more longer than indicating elements 719, above-mentioned mutual contact relation still can be kept.

If satisfy above-mentioned mutual relationship between the contact position between contact position between ink supply needle 714 and the providing ink element 712 and otch part 716 and the sign element 719, can prevent reliably that then the mistake of ink cartridge from packing into, thereby can avoid contingent ink to mix.Yet, if ink supply needle 714 in fact as yet not with ink cartridge in ink contact, ink supply needle 714 and providing ink partly 712 also can form connection between them.Ink supply needle 714 realizes that with ink the position (2) that is communicated with should lag behind the initial position contacting between otch part 716 and the sign element 719.

After forming the ink connection, provide the contact between element 715 and the sensing element 718 to begin to form in information.Information provides element 715 to provide the information of relevant ink cartridge characteristic with the form of resistor.The read assembly 718 of contact form is used to differentiate whether ink cartridge IC is loaded into.When forming contact between them, the providing ink coupling assembling 714 of pen recorder with ink cartridge in ink realize being communicated with.If after contacting, further insert ink cartridge with read assembly 718, prop up up to the front surface 901a of ink cartridge till the ink cartridge installation wall 731 partly of pen recorder, then packing into of ink cartridge just has been done.As shown in this figure, this butt can (3) be located to form in the position.Yet in order to ensure contacting of 718 of resistor 715 and contacts, after they began therebetween contact, they preferably were mutual rubbing contact.Method with guaranteeing the relative position relation between ink cartridge and ink cartridge installation site can guarantee correctly packing into of ink cartridge, thereby can realize providing ink reliably.

When not satisfying this position when concerning, just can not guarantee normally to supply with ink or stably supply with ink to record-header.

Below with reference to Figure 14 A, 14B, 14C, introduce and prevent that another structure that mistake is packed into from constituting.In this embodiment, the surface of safety cover plate 721 is provided with a small lugs (jut) 721A.Ink cartridge is provided with a groove 750 that allows small lugs to pass through.

It is distinctive position that projection 721A is arranged on respect to this color, and for example being arranged on apart from the distance of cover plate one side is l ₁The position.It is distinctive position that groove 750 on the ink cartridge also is arranged on corresponding to this color, and for example, being arranged on apart from the distance of ink cartridge one side is l ₂The position.If the ink of color of the same race, projection on the safety cover plate and the groove on the ink cartridge (l that matches each other ₁=l ₂), therefore, they can suitably mesh, and allow packing into of this ink cartridge.If ink cartridge is encased on the wrong position, projection on the safety cover plate and the groove on the ink cartridge (l that can not match each other ₁≠ l ₂), therefore, projection will prop up shell body in its front side, to stop the further insertion of ink cartridge.Thereby the mistake that can prevent ink cartridge is packed into.And if ink cartridge is inserted into wrong installation site, this insertion will be stopped halfway, thereby the operator can be easy to pick out this errors present.Compare with aforesaid embodiment, it can identify mistake and pack on distance ink supply needle position quite far away, thereby can further guarantee its safety.In addition, projection 721A can also guide the insertion of ink cartridge effectively, thereby has the advantage that can suitably aim at ink supply needle, has improved operability.

Below with reference to Fig. 4, introduce the mechanism that is used to detect ink tank ink inside recoverable amount.Fig. 4 is the plan view from above of ink tank.Ink tank 701(701BK, 701C, 701M 701Y) is box-like, and has an ink as the providing ink source to possess partly and a residual ink receptacle.Ink cartridge is contained on the master component of pen recorder with removably.Providing ink pipeline 703(703BK, 703C, 703M 703Y) possesses part with the ink of ink tank and is connected.Residual ink pipeline 707(707BK, 707C, 707M 707Y) is used for forming connection between the residual ink receptacle of pump 440 and ink tank.

In this embodiment, should be specifically noted that the configuration mode of the relevant ink tank of following introduction.

If the color difference, then because of their composition difference, it also is different that the curing characteristics of ink increases characteristic with viscosity.For example, according to black, blue-green, magneta colour and yellow order, its viscosity raises and solidifies easier successively.This viscosity raises and curing if take place in ink supply system, and this ink supply system is with blocked.In this example, supply line is made of polyethylene pipe.But, no matter use which type of supply line material, enter through tube wall always have little air, also always have ink solvent vaporization evaporation.Therefore, the air capacity that is introduced into and the evaporation capacity of ink solvent all will increase along with the increase of supply line length.

Consider above-mentioned situation,, then can set gradually each ink tank by this side to providing ink place according to viscosity rising and the easy degree of solidifying if each supply line all stretches in (left side in figure) to same direction.In other words, the viscosity of ink raises and solidifies easily more, and its used length of pipeline just should short more (in the drawings, black, blue-green, magneta colour and yellow ink container set gradually from left to right according to the English name order).By adopting this set-up mode, if the viscosity of ink raises and curing ratio is easier to, the introducing of its air and the evaporation of solvent are also smaller.This is equally applicable to residual ink and accommodates system.

Ink recoverable amount detection means 800 is arranged between the ink holding portion and providing ink pipeline 703 of ink tank 701.Include in the cable 707 and variously be used for detection means 800 and be used to detect whether installed circuit of ink tank.What label 709 was represented is a connector.

Fig. 5 A is the plan view from above of an ink pressure detection means, and Fig. 5 B is its vertical view.Ink passage member 801 has an internal ink passage 803, and is made of crown member 801A and base member 801B.Crown member 801A has a garden shape perforate 805.An annular membrane 807 is sandwiched between crown member 801A and the closure elements 809 at its periphery, topped the neighboring area of opening 805.Four bights at crown member 801A are provided with fixing stopping element (tightening member) 811, and they pass formed through hole 813 vertically at four angles of closure elements 809 respectively.813 upper outside partly is formed with step 813A in the hole.Tightening member 811 has rebound resilience, and has engagement to collude 811A in its end arranged outside.Engagement is colluded 811A and is had one and be skewed end face.

In the through hole 813 of closure elements 809, be provided with tightening member 811.Collude the chimeric mutually of 811A and step 813A by engagement, can be fixed on closure elements 809 on the crown member 801A, thereby film 807 is clamped between crown member 801A and closure elements 809.Top perimeter surface at crown member 801A, a projection part 881 is arranged, and in the lower surface of closure elements 809, the otch part 883 of its position corresponding to this projection part 881 arranged, chimeric by between them, closure elements 809 will be positioned and be fixed on the crown member 801A.

In the centre of film 807, be provided with a supporting member 815, to seal its interior side hole.The base portion of engaged element 817 is fixed on the supporting member 815 with screw or its analog, so that make overhang 815A(on the end face of it and supporting member 815 be positioned at the center of perforate 805) tabling.Engaged element 817 has two and has elastic vertical engagement part 819.Each engagement part 819 all has an engagement to collude 819A in the outside of its end.The top that 819A is colluded in engagement also is skewed.These two engagements partly 819 are separately positioned on by the relative position place on the diametric(al) at perforate 805 centers.

In the center of closure elements 809, be formed with a vertical through hole 821.Two engagement parts 819 are arranged in through hole 821.In through hole 821, be provided with a coiled type spring 823 and a spring compression ring 825.Spring 823 is supported on and is arranged on two engagement part bottom 819 outsides, through hole 821 ring-shaped protrusion parts (spring acceptor).Spring compression ring 825 side within it colludes the 819A tabling with engagement engagement partly.When being in this state, the top of spring 823 has been depressed.Spring 823 is compressed by two parts (annular projection is 821A and spring limit collar 825 partly).Therefore, because the bounce (if ignoring the effect of the ink pressure in ink channel 803) of spring, film 807 and supporting member 815 will be pulled upwardly, thus make supporting member 815 top perimeter partly, can with annular projection partly the basal surface of 821A contact.

Be formed with an otch part 827 and the bottom of Dutch oral area part 827 in a side of closure elements 809.Pair of conductive contact 829 and 831 center partly should be fixed.Two contacts 829 and an end of 831 pass and are formed on the partly hole 827A of 827 bottoms of otch, partly contact the bottom surface of 821A with annular projection, the other end of two contacts is connected with 837 with the lead-in wire 835 of drawing from connector 833, so that and ink recoverable amount testing circuit realization electrical connection.By the bounce that spring 823 is provided, the top perimeter that two contacts 829 and 831 basal surface will be pushed to supporting member 815 is (conduction) partly, thereby can realize the electrical connection between them.

Above-mentioned pressure detection device can be assembled as follows easily.Film 807 is placed in the perforate 805 of pass element 801, and closure elements 809 is fallen from the top of pass element 801, each tightening member 811 and hole, 4 angles 813 are aligned.The dip plane, top that makes the engagement of tightening member 811 collude 811A props up the inside edge in hole 813, exerts pressure then, each tightening member 811 is tilted inwardly, thereby make it enter (even closure elements 809 falls) in the hole 813.When closure elements 809 fastened film 807 at its top when, 811A was colluded in the engagement of tightening member 811, because its bounce (recuperability) will act on the step 813A, and form chimeric.Therefore, closure elements will be positioned and be fixed on the crown member 801A.

Then, spring 823 is sent in the hole 821, and its bottom is dropped on the annular projection part 821A.Spring compression ring 825 is placed on two engagement parts 819, and it is depressed.Like this, the sloped top face that 819A is colluded in the engagement of two engagement parts 819 will be pushed down by the inside edge of spring compression ring 825.Because its elastic reaction, two engagement parts 819 will tilt to the inside, thereby spring compression ring 825 is fallen.Then, two engagements are partly 819 because its bounce and outward-dipping once more, thereby make two engagements collude the inside top surface that 819A is entrenched in spring compression ring 825.By this way, spring compression ring 825 can be connected with two engagement parts 819.Spring 823 is compressed by spring compression ring 825 and annular projection part 821A.Contact 829 and 831 can be arranged on the closure elements 809 in advance.

Adopt this structure to constitute, the distance between spring compression ring 825 and annular projection part 821A is constant, and therefore, the force of compression of spring 823 (bounce) can remain in the predetermined scope.Film 807 can respond the vacuum state in the ink channel 803 is responsive in preset range, and makes supporting member 815 discharge contact elements 829 and 831.

Therefore, if adopt ink pressure detection means in the present embodiment, need not regulate, the pressure that is detected promptly is in its ink recoverable amount and keeps in the stable scope, referring among Fig. 7 shown in the arrow A.

In general, when balladeur train remains static or be mobile, (do not comprise between the balladeur train return period), can utilize this ink detector to detect ink pressure in the ink channel.Below in conjunction with accompanying drawing 6A and 6B, this is given and introduction.When balladeur train 851 towards the left side or right side when returning, the ink in the ink channel 853 will be subjected to the effect of the inertial force of direction as shown by arrows.Because towards between the return period of left side, this inertial force will be attached on the vacuum pressure, and to the right between return period, it also will add a pressure, and therefore, this will produce certain influence.Therefore, can detect the correct quantity of ink of possessing in the ink cartridge 857 with this ink detector 855.

Fig. 8 A and 8B are the plan view from above and the longitudinal cross-section views of a kind of ink pressure detection means (ink is visited the inspection device), and this device is not adopted by the present invention.This detection means comprises a pass element 859 and a closure elements 863 with internal ink passage 861.Hold a film 865 at element 859 and 863 therebetween.Be arranged on the center part 867A of the supporting member 867 in film 865 centres, projection by the through hole 869 that is positioned at closure elements 863 centers.Therein the heart partly 867A than upper part, be threaded into a ring modulator 871.Spring 873 is compressed by the annular projection of 869 bottoms, hole part 869A and regulator 871.When the ink pressure in the ink channel 861 is higher than some predetermined negative pressure, film 865 and supporting member 867 will be elevated owing to the bounce effect of spring 873, and be positioned at annular projection partly two contacts 875 on the 869A bottom surface and 877 end, also the top perimeter that will be supported element 867 is partly pushed down, thereby makes that realization is electrically connected between them.Adopt a kind of like this structure, when the ink pressure in the ink channel 861 is lower than predetermined negative pressure P, film 865 will be made responsive response to this, and supporting member 867 is fallen.Its result is exactly that the end of supporting member and contact 875 and 877 is separated, and can detect this predetermined negative pressure in view of the above.Therefore, by contact 875 and 877 detected negative pressure, corresponding with the bounce of spring 873.

Yet,, need carry out the adjusting operation of very inconvenience, with the level of definite negative pressure that will detect for this class ink pressure detecting device.In the logical journey of assembling, only come compression spring 873 by rotary actuator 871, the pressure-reduction level that is detected can not be settled out.Fig. 7 shows an example that concerns between ink recoverable amount (gram) in ink cartridge and the ink channel ink inside negative pressure.In order to obtain the detection negative pressure of 65 ± 5 millimeters of water, need utilize regulator 871 to adjust the pressure of spring 873 very finely, this is very inconvenient.
