Next, will print cartridge 40 be described referring to figs. 3 to Fig. 6.White thick arrow among attention Fig. 6 is represented supply lines, and regular point expression signal line.Like Fig. 3 and shown in Figure 4, each print cartridge 40 comprises the housing 41 with almost parallel hexahedral shape.As shown in Figure 4, housing 41 set inside: black dispatch tube 43, optical sensor 69 (detecting unit), memory cell 125 that is filled with China ink bag 42 (the black accomodating units), an end of China ink and 42 connections of China ink bag and the controller 90 (second controller) that is connected with memory cell 125 with optical sensor 69.China ink bag 42 has the extension 42a that the left lower area at Fig. 4 stretches out left.One end of China ink dispatch tube 43 is connected to this extension 42a.
As mention in the early time, the size of print cartridge 40 that is used to hold black ink is bigger and have the black memory capacity bigger than other three print cartridges 40 than other three print cartridges 40, but this difference only is reflected among the chamber 41a, and China ink bag 42 is bigger on sub scanning direction.Because four print cartridges 40 have the identical structure of essence, the description of following print cartridge 40 will be suitable for all print cartridges 40.
Like Fig. 4 and shown in Figure 5, black dispatch tube 43 comprises the pipe 65 that is connected to China ink bag 42, be connected to the pipe 44 of pipe 65 and be coupled to the pipe 45 of an end (left end among Fig. 4) of pipe 44.As shown in Figure 5, the ink passage 66a (second portion) that on sub scanning direction, extends is formed on the inside of pipe 65.Pipe 65 is made up of minor diameter 65a and the large-diameter portion 65b with internal diameter bigger than the internal diameter of minor diameter 65a.Cap 67 is set at the end with regard to sub scanning direction (top among Fig. 5) of pipe 65.
The ink passage 66b (first) that on main scanning direction, extends is formed in the pipe 44 and 45.Pipe 44 be connected to pipe 65 large-diameter portion 65b with pipe 45 opposite ends (right-hand member of Fig. 5), thereby ink passage 66b is communicated with ink passage 66a. Ink passage 66a and 66b formation are formed on the passage 66 (liquid transfer path) in the black dispatch tube 43.In this embodiment, pipe 44 and 45 is all constructed by transparent resin material.
Shown in Fig. 3-5, on an end of pipe 44, form annular lip 47.As shown in Figure 5, annular lip 47 is formed the 47A of circular cylindrical portion around the periphery of annular lip 47.Annular lip 47 further is formed with annular protuberance 48.As shown in Figure 4, O shape circle 48a is configured to around the periphery of annular protuberance 48 and the gap between seal casinghousing 41 and the annular protuberance 48.The annular lip 47 of present embodiment constitutes the part of housing 41.
Like Fig. 3, Fig. 5 and shown in Figure 6, on the outer surface of annular lip 47, form contact point 91.Contact point 91 along sub scanning direction with China ink outlet 46a and put.Contact point 91 is connected to controller 90.As the distortion of present embodiment, contact point 91 can be set at any position, as long as contact point 91 is not positioned at the vertical below of China ink outlet 46a.Position outside being arranged on the contact point 91 of signal transduction system under the China ink outlet 46a can prevent to fall contact point 91 from the China ink that China ink outlet 46a oozes.
In addition, electric power input block 92 is set on the side surface of China ink outlet 46a side of housing 41.On housing 41, form stepped surfaces 41c, thereby housing 41 is recessed towards China ink bag 42 on main scanning direction from annular lip 47 between China ink outlet 46a and electric power input block 92.Electric power input block 92 is set at the opposition side with regard to contact point 91 that stepped surfaces 41c went up and on sub scanning direction, be positioned at China ink outlet 46a.In other words, electric power input block 92 is far away from China ink outlet 46a on sub scanning direction than contact point 91 from China ink outlet 46a on the sub scanning direction.As shown in Figure 6, electric power input block 92 is electrically connected to controller 90 and optical sensor 69.Electric power efferent 162 through with tape deck 1 side of describing at the back is electrically connected, and electric power input block 92 is to controller 90 and optical sensor 69 power supplies.As the distortion of present embodiment, electric power input block 92 can be set at any position, as long as this position is not under China ink outlet 46a.
Position outside being arranged on the electric power input block 92 of electrical power transmission system under the China ink outlet 46a by this way prevents that the China ink that China ink outlet 46a oozes from depositing on the electric power input block 92.In addition, through making electric power input block 92 and China ink outlet 46a far away discretely with China ink outlet 46a than contact point 91 discretely, China ink will become and be not easy to deposit on the electric power input block 92, thereby guarantee electric power input block 92 not short circuits and can not damage controller 90 etc.In addition; Through between electric power input block 92 and China ink outlet 46a, forming stepped surfaces 41c; Electric power input block 92 is being separated on the main scanning direction and on the sub scanning direction with China ink outlet 46a considerably, thereby guarantees that further Mo Buhui deposits on the electric power input block 92.
Shown in Fig. 5 (a), first valve 50 (first opening/closing unit) is set at the inside of the pipe 45 of black dispatch tube 43.Second valve 60 (second opening/closing unit) is set at pipe 44 inside of black dispatch tube 43.First valve 50 comprises flexible seal member 51, spherical component 52 and the helical spring 53 that is used to seal the opening that is formed on pipe 45 left ends.Lid 46 is set on the end of pipe 45.Lid 46 prevents that containment member 51 is from managing 45.China ink outlet 46a is formed on and covers in 46.
One end of helical spring 53 contacts with bulbous member 52, and the other end contacts so that spherical component 52 is pushed towards containment member 51 consistently with end difference 45a on being formed on pipe the inner of 45.In the present embodiment, helical spring 53 is used as the pushing member, but pushing member can realize through the device outside the helical spring, as long as spherical component 52 is pushed towards containment member 51.
The elastic component structure that containment member 51 is formed by rubber etc.Containment member 51 has slit 51a, annular protuberance 51b and bend 51c; This slit 51a penetrates the central authorities of containment member 51 on main scanning direction; This annular protuberance 51b can be fitted in the end of pipe 45; Bend 51c constitute containment member 51 with bulbous member 52 opposed surfaces, this bulbous member 52 is in by in the annular protuberance 51b area surrounded.Bend 51c has the shape that conforms to the outer surface of bulbous member 52.The diameter of section of slit 51a is slightly less than the diameter of the hollow needle of describing the back 153.Therefore, when hollow needle 153 is inserted among the slit 51a, contact with the intimate of hollow needle 153, prevent that China ink is from leaking between slit 51a and the hollow needle 153 thereby containment member 51 flexibly is out of shape the inner surface of slit 51a.
The internal diameter of annular protuberance 51b is slightly less than the diameter of bulbous member 52, and slit 51a is sealed when bulbous member 52 contacts with the inner surface of annular protuberance 51b.More specifically, through contacting between bulbous member 52 and the bend 51c, slit 51a is sealed.In addition, being formed on slit 51a in the containment member 51 helps hollow needle 153 and is inserted in the containment member 51.In addition, because slit 51a is formed in the containment member 51, so although when hollow needle 153 is inserted in the containment member 51 and containment member 51 scraping, also restriction produces the scrapings from containment member 51, and the restriction scrapings gets in the hollow needle 153.Therefore, can prevent to get into the ink passage of ink gun 2 from the scrapings of containment member 51.
Because this structure, shown in Fig. 7 (b), when hollow needle 153 was inserted among the slit 51a via China ink outlet 46a, the end of hollow needle 153 contacted with bulbous member 52 and bulbous member 52 is promoted to leave bend 51c and annular protuberance 51b.At this moment, first valve 50 switches to open mode from closed condition.In addition, when first valve 50 was in open mode, the hole 153b that is formed in the hollow needle of describing in the back 153 had passed through slit 51c.Therefore, hollow needle 153 is communicated with ink passage 43a.On the contrary, when hollow needle 153 moves with when slit 51a withdraws in opposite direction, the pushing force of helical spring 53 makes bulbous member 52 move towards annular protuberance 51b.When annular construction member 52 contacted with annular protuberance 51b, first valve 50 was changed back closed condition from open mode.Along with hollow needle 153 is further pulled out from slit 51a, bulbous member 52 closely contacts with bend 51c.By this way, based on the insertion or the withdrawal of hollow needle 153, first valve 50 takes to allow the open mode and the closed condition of interrupting the connection in the black dispatch tube 43 of the connection in the black dispatch tube 43.First valve 50 in addition,, first valve 50 is used for, so through simple structure, can suppress China ink and leak from first valve 50 with the helical spring 53 of bulbous member 52 towards containment member 51 pushings because being provided with.
On the other hand; When valve member 61 is in shown in Fig. 5 (b) O shape circle 62 with position (open position) that the inner surface of large-diameter portion 65b separates; Second valve 60 is in open mode, and wherein valve member 61 allows the China ink among the ink passage 66a to flow to ink passage 66b via second valve 60.Promptly when second valve 60 was in open mode, ink passage 66a and ink passage 66b fluid were communicated with.And no matter valve member 61 still open positions in the closed position, cannelure 61b and O shape circle 63 all are positioned to lean on than the connecting portion from ink passage 66a and ink passage 66b from cap 67.Therefore owing to contact between the inner surface of O shape circle 63 and large-diameter portion 65b, so the connecting portion of ink passage 66a and ink passage 66b not be formed on large-diameter portion 65b in the space fluid of cap 67 sides of valve member 61 be communicated with.
Like Fig. 4 and shown in Figure 5, switching mechanism 80 (mutual interlocking gear) is set in the housing 41.Switching mechanism 80 is operated so that second valve 60 opens and closes with the operation of actuator 70 (see figure 6)s that the back is described linkedly.Switching mechanism 80 has rod component 81 (mobile member) and helical spring 82, and rod component 81 extends on sub scanning direction.End with regard to sub scanning direction of rod component 81 is fixed to valve member 61, and the other end is projected into outside the large-diameter portion 65b via the opening 67a that is formed in the cap 67.Even when valve member 61 is positioned at the closed position with passage 66, the jag of rod component 81 also keeps exposing outside the large-diameter portion 65b.Roller 83 is set on the jag of rod component 81 and is supported on it with rotatable mode.It is inner that helical spring 82 is set at large-diameter portion 65b.One end of helical spring 82 contacts with valve member 61, and the other end contacts with cap 67.Helical spring 82 pushes towards minor diameter 65a valve member 61 is constant.
Though adopt helical spring 82 as the pushing member in the present embodiment, can use the pushing member outside the helical spring, as long as this member pushes valve member 61 towards minor diameter 65a.Opening 41a be formed on housing 41 in the nearest side of China ink outlet 46a, be on the main scanning direction jag opposed position with rod component 81.
Therefore, when optical sensor 69 not with roller 83 in the face of the time because from the light of light-emitting component output not by roller 83 reflections and thereby do not received by light receiving element, so optical sensor 69 is to controller 90 output signal B.Based on this signal B, controller 90 can confirm that second valve 60 is in closed condition.On the other hand, when optical sensor 66 and roller 83 are opposed, because receive by roller 83 reflections and by light receiving element, so optical sensor 69 is to controller 90 output signal A from the light of light-emitting component output.Based on this signal A, controller 90 can confirm that second valve 60 is in open mode.
In other words, by the signal A of the optical sensor 69 output open mode corresponding to second valve 60, and signal B is corresponding to the closed condition of second valve 60.Thereby controller 90 can confirm whether second valve 60 blocks ink passage 66a, and can export corresponding detection signal.Through detecting the mechanical displacement that is included in the roller 83 in the switching mechanism 80 with optical sensor 69, ink-jet printer 1 can detect the open and-shut mode of second valve 60 more reliably.
As shown in Figure 4, memory cell 125 is set on the tabular component 49.Tabular component 49 is fixed to cylindrical body 48, is positioned at the opposition side of annular lip 47.The sequence code of data with the type of expression print cartridge 40 of scheduled wait time is specified in memory cell 125 storages.Stand-by period is that the required time is calmed down in the black pressure oscillation in the China ink bag 42 when print cartridge 40 is installed in the installation unit of describing the back 150.
Because print cartridge 40 is moved when the user is installed in print cartridge 40 in the installation unit 150, this moves and can in China ink bag 42, produce black pressure variation.Be delivered to ink gun 2 if pressure changes via ink-feed channel 154, then exist to be formed on the ruined possibility of meniscus on the spray-hole, this spray-hole is formed in the ink gun 2.
Yet; As will be described in detail later; The process stipulated time after print cartridge 40 is installed in the installation unit 150; According to the ink-jet printer 1 of present embodiment second valve 60 is changed to open mode from closed condition, to open the ink-feed channel 154 that the China ink bag 42 in the print cartridge 40 is connected to ink gun 2.Therefore, the China ink in the China ink bag 42 is not supplied to ink gun 2, and the black pressure up between installation period changes and alleviated, thereby reduces the ruined possibility of meniscus in the spray-hole.
If should the stipulated time too short, then the China ink in the China ink bag 42 will change at black pressure and be supplied to ink gun 2 before being alleviated, and meniscus is had adverse effect.Yet, do not preferably set the oversize stipulated time yet, wait for the long period because the user is essential before can printing.Therefore, in this embodiment, through the imagination contingent maximum pressure variation and should the China ink pressure oscillation be relieved to the required time of degree of not destroying meniscus and calculate the recommendation of this stipulated time when the user is installed in print cartridge 40 in the installation unit 150.This time is stored in the memory cell 125 recommendation as this stipulated time.This method realizes preventing that black meniscus from destroying and reducing the best balance between the stand-by period that the user carries out recording operation.Here, to be preferably set to black capacity more greatly then long more the stand-by period.The data of memory cell first stipulated time of 125 storage representations in three print cartridges 40 except the print cartridge 40 of storage black ink.The data of memory cell second stipulated time of 125 storage representations of the print cartridge 40 of storage black ink, this second stipulated time is longer than first stipulated time.
In addition, the external device (ED) except ink-jet printer 1 can easily be used to rewrite the data of the China ink amount in the expression print cartridge 40.Therefore, be re-filled and the different China ink amount of initial China ink amount if used up the print cartridge 40 of China ink, then external device (ED) can be used to rewrite data that the expression China ink in the memory cell 125 measures so that reflect the variation of this specification.Through said memory cells 125 is set also therein in print cartridge 40, can reduce the memory capacity that the memory cell in the printer body needs with above-mentioned all storage.
Next, will the installation unit 150 in the body that be formed on ink-jet printer 1 be described with reference to figure 6 and Fig. 7.On sub scanning direction and four installation units 150 putting be set in the printer body, be used for when print cartridge 40 is installed to printer body, receiving each print cartridge 40.Because installation unit 150 has same general configuration, so the following only installation unit that will describe in the installation unit 150.
As shown in Figure 7, installation unit 150 has the recess 151 that conforms to the outer shape of print cartridge 40.Recess 151 have on main scanning direction to inner 151a.Hollow needle 153 (hollow tube), ink-feed channel 154, the contact point 161 that is electrically connected with controller 100, electric power efferent 162 and actuator 70 are set on inner 151a, and wherein this electric power efferent 162 is used for exporting the electric power that is produced by the power subsystem that is arranged on printer body 200 (see figure 6)s.
Hollow needle 153 is by the slit 51a opposed position of the print cartridge that is arranged on regularly and installs 40 and longitudinally directed along main scanning direction.Hollow needle 153 has the interior hollow region 153a that is communicated with ink-feed channel 154 fluids and terminal is used to provide the hole 153b that makes hollow region 153a and external communications (also seeing Fig. 7 (b)) with being formed near it.Because this structure, when print cartridge 40 is installed in the printer body and hole 153b during through slit 51a, hollow needle 153 is in the state that is communicated with pipe 45 sides of ink passage 66b.Yet when when print cartridge 40 is in slit 51a inside by hole 153b when printer body is removed, being communicated with between hollow needle 153 and the ink passage 66b is interrupted.Be communicated with though note when hole 153b passes through slit 51a, between hollow needle 153 and ink passage 66b, setting up, China ink also from China ink bag 42 inflow hollow region 153a, is changed to open mode up to second valve 60.The path of the spray-hole in addition, from the hole 153b of hollow needle 153 to ink gun 2 is the airtight sealing passage that is not exposed to outside atmosphere.Therefore, because the China ink in these passages is not exposed to atmosphere, increase so can suppress black viscosity.
Reflection type optical sensor 170 (detecting unit) is set in each installation unit 150, near the opening of corresponding recess 151.Optical sensor 170 is connected to controller 100 and is used to detect having or not of protuberance 41d, and this protuberance 41d is formed on the outer surface of the housing 41 that constitutes print cartridge 40.Optical sensor 170 comprises light-emitting component and light receiving element, and whether receives light and export signals to controller 100 based on light receiving element.Particularly, export signal C, and export and signal C various signals D when light receiving element does not receive light time optical sensor 170 when light receiving element receives light time optical sensor 170.
Shown in Fig. 7 (b), when print cartridge 40 is installed in the installation unit 150 fully (in installation time, first valve 50 changes to open mode), optical sensor 170 is opposed with protuberance 41d.Because this moment, the light from light-emitting component output received by protuberance 41d reflection and by light receiving element, so optical sensor 170 is to controller 100 output signal C.By this way, controller 100 can detect the installation of print cartridge 40 in installation unit 150 and when accomplish (when first valve 50 switches to open mode from closed condition).
When print cartridge 40 by when installation unit 150 is removed, shown in Fig. 7 (a), optical sensor 170 is not positioned in the opposed position with protuberance 41d, therefore from the light of light-emitting component output by protuberance 41d reflection and do not received by light receiving element.Therefore, optical sensor 170 is to controller 100 output signal D, and controller 100 can detect print cartridge 40 and not be installed in (first valve 50 is in closed condition) in the installation unit 150 thus.
Therefore, optical sensor 170 output signal C are installed in (first valve 50 is in open mode) in the installation unit 150 with expression print cartridge 40, and output signal D is not installed in (first valve 50 is in closed condition) in the installation unit 150 with expression print cartridge 40.Through using optical sensor 170 to detect the relative position of protuberance 41d and hollow needle 153 (installation unit 150); Controller 100 can be distinguished when print cartridge 40 is installed to installation unit 150 neutralizations and not be installed in the installation unit 150, and can detect the open and-shut mode of first valve 50.Through this simple structure, can be at the state of the operation that does not directly detect first valve 50 itself open and-shut mode of detection first valve 50 down.
Like Fig. 2 and shown in Figure 6, housing 1a inside also is provided with buzzer 13.Controller 100 control buzzers 13, for example when making a mistake in one at second valve 60 and optical sensor 69, send various sound notification users when print cartridge 40 normally is not installed in its installation unit 150 and during ink-jet printer 1 ready-to-print.
Next, will the operation that the controller 90 of controller 100 and the print cartridge 40 of ink-jet printer 1 when print cartridge 40 is installed in the body of ink-jet printer 1 carries out be described with reference to figure 8.When through opening the door 1c on the printer body and gradually print cartridge 40 being inserted into user in the installation unit 150 when print cartridge 40 being installed in the body of ink-jet printer 1, the processing of describing among beginning Fig. 8.In this operating period, hollow needle 153 is inserted among the slit 51a that is formed in the containment member 51 gradually, and between contact point 91 and contact point 161 and between the contact point 163 of electric power efferent 162 and the electric power input block 92, sets up and be electrically connected.Through these connections, controller 90 is electrically connected to each other with controller 100 and can exchanges signal.Simultaneously, electric power is supplied to controller 90, actuator 70, memory cell 125 and optical sensor 69.
Shown in Fig. 7 (b), when print cartridge 40 was installed in the installation unit 150, optical sensor 170 was positioned to protuberance 41d opposed, and to controller 100 output signal C.Among the S1 that begins to locate that in Fig. 8, handles, in case receive signal C from optical sensor 170, controller 100 just detects print cartridge 40 and has been installed in the installation unit 150.Shown in Fig. 5 (b), the hollow needle 153 that inserts via slit 51a makes bulbous member 52 separate with annular protuberance 51b, makes first valve 50 move to open mode from closed condition.In addition, be mounted in case detect print cartridge 40, controller 100 just detects the signal of deadline to the fitting operation of controller 90 output expression optical sensors 170.
In case slave controller 100 receives the signal that expression print cartridge 40 is mounted, in S2, controller 90 just reads current China ink amount and the data of stand-by period (stipulated time) the expression print cartridge 40 from memory cell 125.In S3, controller 90 confirms in S2, whether to have read data from memory cell 125.If controller 90 can not read above-mentioned data (S3: not) because data are stored in the memory cell 125; Then in S4; Controller 90 is to controller 100 outputs first rub-out signal; And in case receive this rub-out signal, controller 100 is just controlled buzzer 13 and is sounded, and is not stored in the memory cell 125 to notify user's data.
Yet if confirm successfully to have read data (S3: be) from memory cell 125 at S3 middle controller 90, in S5, controller 90 confirms whether the stipulated time passes after installation is detected.Controller 90 does not continue to wait for (S5: not) when passing at the appointed time.When the stipulated time passes (S5: be), in S6, controller 90 is exported signals to controller 100, instruction control unit 100 operated actuators 70, in a single day and receive this signal, controller 100 just start-up control is operated with operated actuator 70.Through this operation, shown in Fig. 5 (b), actuator 70 moves so that rod component 71 further extends in first valve 50 rod component 71 on main scanning direction.
On the other hand, after controller 100 outputs first rub-out signal, in S12, controller 90 waits for that default time passes after being detected in installation at S4 middle controller 90.The data of expression default time are stored in the memory cell of printer body.Default time is that the fluctuation in the black pressure is relieved to the required enough time of the degree of not destroying meniscus and longer than the stipulated time.After default time passed, controller 90 advanced to S6.
Through actuator 70 this operation, the tip of rod component 71 pass the opening 41a that is formed in the housing 41 and be inserted into roller 83 and cap 67 between.Along with the tip of rod component 71 is inserted into, roller 83 is forced among Fig. 5 along tapered portion 71a upwards.Therefore, valve member 61 also moves up with roller 83 in Fig. 5, is transformed into from the position of passage 66 withdrawals from the position of passage 66.By this way, second valve 60 is transformed into open mode from closed condition, allows the China ink in the China ink bag 42 to flow into hollow needle 153 via black dispatch tube 43.Therefore, China ink can be fed to ink gun 2 from print cartridge 40.At this moment, roller 83 is positioned at and optical sensor 69 opposed position, makes the signal A of optical sensor 69 to the open mode of controller 90 output expressions second valve 60.
In S7, controller 90 confirms whether the operation of actuator 70 is accomplished and continuation wait (S7: not) when the operation of actuator 70 is not accomplished.Whether the operating time that begins to be stored in the memory cell (not shown) in memory cell 125 or the printer body through the operation of confirming from actuator 70 passes, and whether the operation of controller 90 definite actuators 70 is accomplished.
Therefore, if the operating time passes (S7: be), then in S8, controller 90 confirms whether second valve 60 is transformed into open mode from closed condition.Particularly, controller 90 is based on the state of confirming second valve 60 from the signal (the signal A of expression open mode and the signal B of expression closed condition) of optical sensor 69 outputs.If controller 90 receives signal B from optical sensor 69; Represent that then second valve 60 still is in closed condition (S8: not); In S9; Controller 90 is to controller 100 output second rub-out signal, and in case receive this second rub-out signal, and controller 100 is just controlled buzzer 13 and sounded to notify one in user's second valve 60, optical sensor 69 and the actuator 70 mistake has taken place.After buzzer 13 is sounded in S9, the processing that controller 100 finishes among Fig. 8.Based on the sound of buzzer 13, if second valve 60 makes a mistake with optical sensor 69, then the user is with the current print cartridge 40 of new print cartridge 40 replacings, and if actuator 70 make a mistake, then the user keeps in repair the printer body of ink-jet printer 1.
Yet as controller 90 when optical sensor 69 receives signal A (S8: be), controller 90 confirms that print cartridges 40 normally are installed in the installation unit 150, and in S10, gets into holding state, promptly prints SBR.In S11, in a single day this prints the signal of SBR to controller 90 to controller 100 output expressions, and receives this signal, and then controller 100 control buzzers 13 send the sound of expression ink-jet printer 1 ready-to-print.The operation of at this moment, print cartridge 40 being installed is accomplished.
Next, with describing the operation of when printer body is removed, being carried out when print cartridge 40.When print cartridge 40 had been used up China ink, for example, the operator opened a 1c and removes print cartridge 40 from printer body.Along with print cartridge 40 shifts out printer body, protuberance 41d moves to not and optical sensor 170 opposed position, and optical sensor 170 is begun to controller 100 output signal D.As a result, controller 100 identifies first valve 50 and is in closed condition, and print cartridge 40 is just removed from printer body.Next, controller 100 is to the control signal of controller 90 output function actuators 70.In case receive this control signal, controller 90 is just controlled actuator 70 with withdrawal rod component 71.Along with rod component 71 is contracted, second valve 60 changes to closed condition from open mode, thereby blocks the ink passage in the black dispatch tube 43.At this moment, roller 83 is not opposed with optical sensor 69 on main scanning direction, and therefore, optical sensor 69 is to controller 90 output signal B.Therefore, controller 90 is to the signal of the closed condition of controller 100 output expressions second valve 60.Controller 90 continues the signal to the closed condition of controller 100 output expressions second valve 60, up to contact point 91 and contact point 161 (central authorities that promptly 153b has passed through slit 51a up to the hole) separated from one another.
Continue by when installation unit 150 is removed at print cartridge 40, hollow needle 153 is extracted out from the slit 51a of containment member 51, and all breaks off between contact point 91 and the contact point 161 and between electric power input block 92 and the contact point 163 and connecting.Afterwards, the user changes the print cartridge of having removed from printer body 40 with new print cartridge 40, according to said process new print cartridge 40 is installed in the printer body.
When for example in printing ink gun 2 China ink is ejected on the sheet material P; And because the fault of actuator 70, power issue etc.; An actuator through the control of controller 100 in the actuator 70 is made the second corresponding valve 60 when open mode moves to closed condition by operation, and optical sensor 69 is to controller 90 output signal A.In case receive this signal, controller 90 is just represented the signal of second valve, 60 closed conditions to controller 100 outputs.In case receive this signal, controller 100 is just controlled ink gun 2 and is suspended ink-jet, and control feed roller 25, conveying roller 26, supply unit 21 and conveying roller 28 are to be discharged to the current sheet material P that is printed on the paper discharge unit 11.Thereby controller 100 suspends from ink gun 2 ink-jets when being placed in closed condition regardless of which kind of reason second valve 60.This can prevent the ink passage that leads to ink gun 2 from second valve 60, to produce because the big negative pressure that continues to produce from ink gun 2 ink-jets.Avoid the generation of negative pressure can prevent that near the meniscus that forms the jet in the ink gun 2 is destroyed and prevents that air from getting into these openings.
For the ink-jet printer 1 according to the foregoing description, the stipulated time (first stipulated time and second stipulated time) after print cartridge 40 is installed in the corresponding installation unit 150, second valve 60 of print cartridge 40 is switched to open mode.Therefore, after print cartridge 40 is installed in the installation unit 150 and up to black bag 42 ink passage that is connected to ink gun 2 that forms print cartridge 40, produce the time difference that equates with the stipulated time.Thereby, change even when print cartridge 40 is installed in the installation unit 150, in China ink bag 42, produce black pressure owing to the motion of print cartridge 40, after this pressure variation was calmed down, the China ink in the print cartridge 40 just was supplied to ink gun 2.Therefore, the ink-jet printer 1 of present embodiment can prevent to be formed on the destruction of the black meniscus that forms in the jet of ink gun 2.
The data of 125 storage representation stipulated times of memory cell, when the initial China ink amount in the print cartridge 40 was big more, this stipulated time was long more.Therefore, even when the print cartridge (box of storage black ink) comprise the Da Mo amount is installed, present embodiment also guarantee black pressure change calmed down before China ink in the print cartridge 40 be not supplied to ink gun 2.Therefore, can suppress to be formed on the destruction of the black meniscus in the jet of ink gun 2 better according to the ink-jet printer 1 of present embodiment.
In addition, when print cartridge 40 by when the body of ink-jet printer 1 is removed, second valve 60 is placed in closed condition.Because the connection that second valve 60 blocks among the ink passage 43a is so if when first valve 50 is switched to closed condition, be damaged, then second valve 60 can suppress the ink leakage amount.
Modification as present embodiment; Replace being arranged on the optical sensor 170 in the printer body; Sensor 270 can be set in the print cartridge, is used for producing the signal (first valve 50 is in open mode or closed condition) whether expression print cartridge 40 is installed in installation unit 150.Fig. 9 is the block diagram that illustrates according to the electrical construction of ink-jet printer of this modification 1 and print cartridge 40.As shown in Figure 9, sensor 270 is to controller 90 output signals, and controller 90 is transferred to controller 100 with this signal.Sensor 270 can be a reflection type optical sensor for example, and is configured to produce unlike signal when installation unit 150 neutralizations are not installed in the installation unit 150 when print cartridge 40 is installed in.
