Thereby the first black receiving element 13 is supported for and can goes up mobile at the first black receiving element 13 and block unit 12 overlapped directions (vertical direction) with respect to second supporting member 30.Therefore, when the first black receiving element 13 moves back and forth, can absorb swing along horizontal direction.The first black receiving element 13 is supported for and can pivots with respect to second supporting member 30 around fulcrum, and these fulcrums are at the top edge of the sidewall 14b of the second black receiving element 30 and the contact point between the wheel 33 (referring to the solid line of Figure 17 A).Therefore, when the first black receiving element 13 moved back and forth, the enough simple structures of energy absorbed the swing along vertical direction.In addition, because wheel 33 supports a side opposite with second supporting member 30 of the first black receiving element 13, so can stably support the first black receiving element 13.
In addition, shown in Figure 17 B and 17C, one second supporting member 30 in two second supporting members 30 is constructed such that guide rod 20 is free unoccupied place to pass along horizontal direction, and another second supporting member 30 in these second supporting members 30 be constructed such that guide rod 20 without any the space pass.Because these guide rods 20 pass second supporting member 30 like this, so even a guide rod 20 for example in these guide rods 20 also can absorb this distortion by this space when horizontal direction is twisted.Therefore, the first black receiving element 13 can move reposefully.And guide rod 20 passes first supporting member 23 and second supporting member 30.
In this structure, at first will the mechanism that be used to connect the block unit 12 and the first black receiving element 13 be described.When the first black receiving element 13 that is positioned at the black receiving position place shown in Figure 4 and 5 during to the motion of the non-black receiving position as shown in Fig. 2 and 3, the diapire 13a of the first black receiving element 13 enters into the block that is positioned at non-closure position place and coils 18 belows.Then, in block dish 18, be in the approximate horizontal state engaging claw 25 (referring to the solid line of Fig. 8) be arranged in the first black receiving element 13 and dyke 32 collisions contiguous with engaging groove 31.
Then, thus engaging claw 25 moves in Fig. 8 to upper right side tilt (referring to the double dot dash line of Fig. 8) around back shaft 24 under the effect of impact force.Thereby engaging claw 25 sliding dykes 32 more engage with engaging groove 31.Therefore, because engaging claw 25 engages with engaging groove 31, be connected on the first black receiving element 13 with engaging groove 31 so have the block unit 12 of engaging claw 25.
Then will describe, and wherein be in the block unit 12 and the first black receiving element 13 and shown in Fig. 2 and 3, move to the position as shown in Fig. 6 and 7 integratedly by the block unit 12 and the first black receiving element 13 in engaging claw 25 and the engaging groove 31 interconnective states to following situation.When the block a shot unit 12 and the first black receiving element 13 were in the state shown in Fig. 2 and 3, if sledge motor 92 (referring to Figure 12) is driven, then belt pulley 22 and belt 21 rotated by the transmission mechanism (not shown).
Then, owing to second supporting member 30 that is connected on the belt 21 moves towards head unit 5 along guide rod 20, so the first black receiving element 13 that is connected on second supporting member 30 also moves towards head unit 5.Therefore, the block unit 12 that is connected on the first black receiving element 13 moves towards head unit 5 integratedly.Then, shown in Fig. 6 and 7, block unit 12 stops at the closure position place, and the first black receiving element 13 stops at black receiving position place.And when the first black receiving element 13 moved, wheel 33 rolled along the top edge of the sidewall 14b of the second black receiving element 14, thereby the first black receiving element 13 is stably moved.
Then will describe following situation, wherein pass through shown in Fig. 2 and 3 in engaging claw 25 and the engaging groove 31 interconnective states in the block unit 12 and the first black receiving element 13, the first black receiving element 13 irrespectively moves to black receiving position with block unit 12.
In this case, at first starting solenoid 28 throws off engaging claw 25 and engaging groove 31.As shown in Figure 8, when being not activated solenoid 28, the disc spring 29 of the connecting rod 28a of leverage component 27 by passing solenoid 28 roughly remains in the level (referring to the solid line of Fig. 8).In this state, if start solenoid 28, then connecting rod 28a overcomes disc spring 29 and moves up, thereby and the leverage component 27 that is connected on the connecting rod 28a moves to lower right tilt (referring to the double dot dash line of Fig. 8) around back shaft 26.Then, an end of the other end of leverage component 27 extruding engaging claw 25.Therefore, thus engaging claw 25 moves to upper right side tilt (referring to the double dot dash line of Fig. 8) around back shaft 24.Therefore, the engaging claw 25 that engages with engaging groove 31 is thrown off with engaging groove 31.
If in this state according to driving sledge motor 92 (referring to Figure 12) with the similar mode of above explanation, then owing to engaging claw 25 is thrown off with engaging groove 31, so have only the first black receiving element 13 to move, and finally stop at the black receiving position place shown in the Figure 4 and 5 along guide rod 20.
Demonstrate to this embodiment example, the combination of the first black receiving element 13, guide rod 20, belt 21, belt pulley 22, first supporting member 23, engaging claw 25, second supporting member 30, engaged groove 31 and sledge motor 92 is as first travel mechanism, and this first travel mechanism makes block unit 12 move back and forth between closure position and non-closure position along the direction of arrow D.In addition, demonstrate to this embodiment example, the combination of guide rod 20, belt 21, belt pulley 22, second supporting member 30 and sledge motor 92 is as second travel mechanism, and this second travel mechanism makes the first black receiving element 13 move back and forth between black receiving position and Fei Mo receiving position along the direction of arrow D.Owing to be used to make block unit 12 first travel mechanism that moves and the shared guide rod 20 of second travel mechanism and the sledge motor 92 that are used to the first black receiving element 13 is moved, so can reduce number of components.Therefore, can reduce the cost of this imaging device 1.Then be elaborated with reference to Fig. 2 to 7 and 9 pairs of block unit 12.Fig. 9 A is
Amplification view, the lip 41 that demonstrates block main body 16 abuts against nozzle and forms lip-deep state.Fig. 9 B is the amplification view of lip 41.Fig. 9 C is the amplification view of film 43.And in Fig. 9 A, block dish 18 does not demonstrate.
Six block main bodys 16 that are arranged side by side on the block dish 18 become corresponding with record head 5a to 5f along the direction identical with the arranged direction of a placement record 5a to 5f and with the pitch arrangement identical with the arrangement pitch of record head 5a to 5f.
Shown in Fig. 9 A, each block main body 16 has tabular pedestal part 40, those lips 41, opening 42, film 43, vertical wall 44, reinforced wall 45 and bonding part 46.This base portion 40 forms the surface in the face of the nozzle of each record head among the record head 5a to 5f.Lip 41 forms the surface setting from the periphery of base portion 40 towards nozzle, forms on the surface thereby can abut against nozzle.These openings 42 pass and open base portion 40.These films 43 cover these openings 42.These vertical walls 44 extend along the side that erects with lip 41 in the opposite direction from the periphery of base portion 40.These reinforced walls 45 extend internally from the inner surface of vertical wall 44.These bonding parts 46 stretch out so that engage with block support 17 along horizontal direction from the lower end of vertical wall 44.
Among the parts that constitute each block main body 16, the parts except lip 41 and film 43 are become one by resin-shaped.Lip 41 is formed by the resin of elasticity greater than these parts, and is fixed on the base portion 40 by thermal weld.Specifically, lip 41 is formed at about 10 degree to the rubber in the scope of about 20 degree by JISA hardness.According to these character of lip 41, when lip 41 abutted against nozzle and forms the surface and go up, lip 41 can form the surface with nozzle and closely contact.Therefore, can improve and be used for the air-tightness of enclosure space that valve nozzles forms the surface.Therefore, when this imaging device 1 did not use, the China ink that can suppress in the nozzle was dry.
In addition, shown in Fig. 9 B, each lip 41 forms the chevron that has a summit in cutaway view.The radius of curvature R on this summit is approximately 1.0mm.According to this structure of lip 41, lip 41 can form the surface with nozzle and further closely contact.
In addition, the maximum height h of each lip 41 to the scope of about 2.0mm, and preferably approximately is 1.5mm at about 1.0mm.The Breadth Maximum w of each lip 41 to the scope of about 2.5mm, and preferably approximately is 2.0mm at about 1.5mm.That is to say that the maximum height h of this lip is about 0.75 to 2.5 times of Breadth Maximum w of lip, preferably approximately is 1.3 times.
According to this structure of these lips 41, the space that is formed surface, base portion 40 and lip 41 encirclements by nozzle can be done as far as possible for a short time.Therefore, further can prevent as far as possible from the China ink of nozzle dry.In addition, when lip 41 abuts against nozzle and forms on the surface, can prevent lip 41 swaying styles.Therefore, lip 41 can stably abut against nozzle and forms on the surface.
Imaging device 1 is aforesaid line head type.Each record head among the record head 5a to 5f of this line head type has big flow nozzle.Therefore, be used for the cleaning operation of head unit 5 of this line head type than the more substantial China ink of string type record head needs with less flow nozzle.If often carry out cleaning operation, then will waste more substantial China ink.According to these lips 41, prevent as far as possible that as mentioned above the China ink in the nozzle is dry, thereby reduce the required number of times that carries out of cleaning operation.Therefore, can reduce the China ink amount of in cleaning operation, wasting.
Each block main body 16 is provided with two openings 42.The position of the quantity of these openings 42, opening 42 etc. is not limited to this embodiment.For example, a plurality of openings 42 can be dispersed in the base portion 40.In addition, base portion 40 can form frame shape, and the whole inside of this framework can form as an opening.
Shown in Fig. 9 C, each film 43 in those films 43 by form from nozzle face side in order lamination nylon film 43a, alumina layer 43d, polyester film 43b and polypropylene film 43c four-level membrane form, wherein alumina layer 43d is deposited on the polyester film 43b.
Each film among the film 43a to 43c is enough thin having flexibility, and has gas barrier.In addition, be deposited on aluminium oxide 43d on the polyester film 43b and have high block steam.Therefore, the gas of 43 pairs of all kinds of this film has excellent isolation, and for example solvent borne China ink or water-based ink also have isolation to the China ink of any kind of.Therefore, have four-layer structure, thereby can realize having the film of flexible and gas isolation simply by this film 43 is formed.
It is to be noted that film 43 is not limited to the combination of three layers of 43a to 43c and aluminium oxide 43d.This film 43 can have and comprises the laminar structure of one deck alumina layer 43d and another layer flexible layer at least.In addition, this film 43 can have multilayer alumina layer 43d.
Replace aluminium oxide 43d, can adopt silica.Aluminium oxide and silica are as long as the thickness that they have several at least dusts just has high gas barrier.
That is to say that before capping, these films 43 are covered with opening 42 (referring to the solid line of Fig. 9 A) in plane.After capping, make these films 43 recessed, thereby the pressure that absorbs in this enclosure space change (referring to the double dot dash line of Fig. 9 A) so that heave towards a side opposite with head unit 5.
As mentioned above, apply malleation by each nozzle and carry out cleaning operation record head 5a to 5f.In other words, the cleaning operation of this embodiment is so-called " pressure wash ".Therefore, needn't in each film 43, otch be set.On the contrary, so-called " suck purge " needs film to have otch, because the otch that suck purge is operated by film comes the enclosure space that nozzle is formed face seal is aspirated.
In addition, even during lip 41 abuts against nozzle and forms on the surface during (during capping) on every side variation of ambient temperature, the interior pressure of enclosure space also changes.But, the same with above-mentioned situation, can absorb this pressure by these films 43 and change.That is to say that when environment temperature raise, these films 43 were heaved so that the pressure that absorbs in this enclosure space changes towards a side opposite with head unit 5.In addition, when falling at ambient temperature, these films 43 are heaved so that the pressure that absorbs in this enclosure space changes towards head unit 5.Therefore, can prevent to destroy owing to the pressure during capping changes the meniscus that causes in the nozzle.Therefore, can keep stable inkjet performance.
These films 43 have the gas barrier that is used for separation gas.By this structure, prevent China ink owing to transmit nozzle to be formed gas in the enclosure space of face seal and dry and remove the saturation state of this enclosure space.
The block main body 16 from substrate 50 predetermined gaps be placed on first vertical wall 51, the bonding part 46 of the main body of blocking a shot simultaneously 16 is inserted in those conjugate foramens of first vertical wall 51.In addition, between block base portion 40 of main body 16 and substrate 50, disc spring 53 is set.These disc springs 53 can be when capping absorption pressure.Lip 41 can be pressed to nozzle and form the surface, the surface is tightr to be contacted thereby these lips 41 form with nozzle.In addition, described a plurality of second vertical wall 52 main body 16 excessive pressure basad 50 when capping that can prevent to block a shot.
In this exemplary embodiment, as shown in Fig. 9 A, three disc springs 53 support the base portion 40 of each block main body 16.The proof resilience power of three disc springs 53 equals 0.5kgf.When capping nozzle and formed the surface, each block main body 16 (lip 41) stably was pressed in nozzle and forms on the surface under the effect of the power of the 0.5kgf that is applied by three disc springs 53.
On the other hand, the meniscus in these nozzles destroys under about 5kPa or bigger pressure condition.The proof resilience power of supposing three disc springs 53 is too big.In this case, even surpass under the situation of 5kPa in the interior pressure that is formed the enclosure space that nozzle is formed face seal that surface, lip 41 and base portion 40 limit during the capping by nozzle, this enclosure space is not opened in block unit 12 yet.Therefore, the meniscus in the nozzle will destroy owing to excessively interior pressure of enclosure space, thereby need cleaning operation.Because the interior pressure of enclosure space increases and the black cleaning operation that destroys like this and avoid waste, the proof resilience power of three disc springs 53 is set at 0.5kgf in this exemplary embodiment for fear of meniscus.In other words, the proof resilience power of these disc springs 53 of block unit 12 is less than the received power in bottom surface of the main body 16 of blocking a shot when the meniscus that crushes in this enclosure space in the bad nozzle.
Specifically, each block main body 16 is 124mm (length) * 19mm (width) * 2mm (degree of depth).When the interior pressure of enclosure space reached 5kPa, base portion 40 and film 43 received the power that forms about 1.20kgf of face side from nozzle.The proof resilience power of three disc springs 53 is that 0.5kgf is less than 1.20kgf.Therefore, before reaching 5kPa, the interior pressure of enclosure space overcomes the elastic force that is applied by three disc springs 53 moves downward block main body 16.Therefore, this exemplary avoids being pressed in the meniscus destruction in the nozzle under the situation about excessively increasing during the capping in enclosure space.
Then be elaborated with reference to Fig. 2 to 7,10 and 11 pairs of first black receiving elements 13.Figure 10 is the cutaway view facing to the first black receiving element 13 of head unit 5 (the first black receiving element 13 is positioned at black receiving position place).Figure 11 is the amplification view that the first black receiving element 13 is cut open along the XI-XI line of Fig. 5.
The diapire 13a of the first black receiving element 13 forms the zone that the nozzle in the surface occupies greater than the nozzle that is arranged on a respective record 5a to 5f.That is to say, even go out under the situation of China ink from all nozzle ejection of each record head 5a to 5f when the first black receiving element 13 is positioned at black receiving position place, the diapire 13a of the first black receiving element 13 also is constructed with the size that can receive the China ink that goes out from all nozzle ejection.
Therefore, can once carry out cleaning operation at each record head 5a to 5f.Therefore, compare with the situation of once carrying out cleaning operation at record head, can be to carry out cleaning operation at a high speed.
In addition, as shown in Figure 3, the diapire 13a of the first black receiving element 13 constitutes has following size, this size makes: when the first black receiving element 13 is positioned at non-black receiving position place, from forming the direction of surface crosswise with nozzle, diapire 13a is overlapping is positioned at the whole block unit 12 at non-closure position place.Therefore, the block unit 12 that is positioned at the first black receiving element 13 at non-black receiving position place and is positioned at non-closure position place can be provided with compactly along the depth direction (direction of arrow D) of imaging device 1.Therefore can reduce the size of this imaging device 1.
In addition, the diapire 13a of the first black receiving element 13 is downward-sloping towards non-black receiving position from black receiving position.Therefore, the China ink that is ejected on the diapire 13a of the first black receiving element 13 that is positioned at black receiving position place by cleaning operation can flow towards the second black receiving element 14 reposefully.
In addition, shown in Fig. 5,10 and 11, on diapire 13a, form six grooves 60 and seven ribs 61.These grooves 60 are from the surface depression of diapire 13a.These ribs 61 are outstanding from the surface of diapire 13a, thereby are provided with on ground, opposite each other with corresponding groove 60.
These grooves 60 make the China ink that ejects from each record head 5a to 5f flow to the second black receiving element 14.These grooves 60 roughly extend along the direction of motion of the first black receiving element 13 is linear.In addition, as shown in figure 11, the cross sectional shape of each groove 60 is roughly V-arrangement.According to this structure of groove 60, China ink can flow fast owing to the capillary force that produces in the China ink in flowing to groove 60.In addition, the cross sectional shape of each groove 60 in these grooves 60 roughly forms V-arrangement.Therefore, the situation that roughly forms U-shaped with groove 60 is compared, and can produce stronger capillary force in the bottom of groove, so China ink can flow reposefully.
In addition, as shown in figure 11, moved in the state of black receiving position at the first black receiving element 13, groove 60 be arranged in the nozzle that is arranged on each record head 5a to 5f under.Therefore, from these nozzles China ink is ejected on the groove 60, therefore the China ink that ejects can flow reposefully along groove 60.
The edge along two guide rods 20 of the edge of the close black receiving position that the sidewall 13b of the first black receiving element 13 is diapire 13a from three sides of diapire 13a and diapire 13a is erect.In other words, the sidewall 13b of the first black receiving element 13 erects from those edges except the edge of the close non-black receiving position of diapire 13a of diapire 13a.
Therefore, can prevent from from the side of close black receiving position or from those side leakage of extending, and can flow towards non-black receiving position along guide rod 20 by the China ink that cleaning operation is ejected on the diapire 13a.
In addition, the zone except groove 60 of the diapire 13a of the first black receiving element 13 is coated with waterproofing membrane.That is to say that this zone has than the regional good water proofing property that forms groove 60.Therefore, the China ink that is ejected on the diapire 13a of the first black receiving element 13 can be collected rapidly in the groove 60, so China ink can flow rapidly.
The first black receiving element 13 also is provided with the comb shape China ink and imports member 62 and wiper 63 except above-mentioned parts.This China ink imports member 62 and is arranged near on the front of black receiving position.This wiper 63 is provided with De Bimo and imports member 62 near black receiving position.
China ink imports member 62 and will form lip-deep China ink by the nozzle that cleaning operation is attached to each record head 5a to 5f and import on the diapire 13a.China ink imports member 62 and forms the comb shape passage, and these comb shape passages make head unit 5 sides be communicated with diapire 13a side, and extend on the scope of record head 5a to 5f along the direction vertical with the direction of motion of the first black receiving element 13.
As shown in figure 10, for the China ink that will be attached on the record head 5a imports the into first black receiving element 13, this path forms from forming spaced surface with nozzle has the position of predetermined gap to extend towards the first black receiving element 13.
Two ends that China ink imports member 62 are fixed on second supporting member 31.Therefore, as mentioned above, when second supporting member 31 moved back and forth, China ink imported member 62 and also moves back and forth with second supporting member 31.This China ink imports member 62 and does not constitute as the first black receiving element 13 and can move both vertically or pivot with respect to second supporting member 31.But, because importing member 62, China ink is fixed on second supporting member 31, can be held in and form spaced surface with nozzle described predetermined gap is arranged so should China ink import member 62, and irrelevant with the motion of the first black receiving element 13.
To import member 62 the same with China ink, wiper 63 along with the vertical direction of the direction of motion of the first black receiving element 13 with the corresponding zone of record head 5a to 5f on erect.In addition, this wiper 63 is removably mounted on the substructure member 64.Two ends of this substructure member 64 are fixed on second supporting member 30.Therefore, the same with China ink importing member 62, wiper 63 also can be held in nozzle formation spaced surface predetermined gap, and irrelevant with the motion of the first black receiving element 13.
According to this wiper 63, when the direction opposite with arrow D moved, can not wipe the nozzle of being removed that is attached to away and form lip-deep China ink by abutting against front end that nozzle forms lip-deep wiper 63 by black guiding elements 62 at the first black receiving element 13.And the China ink of being wiped away by wiper 63 flows downward along wiper 63, and flows on the diapire 13a.Therefore, can remove is not that China ink imports the China ink that member 62 is removed.
Then be elaborated with reference to Fig. 2 to the 7 pair of second black receiving element 14.As shown in Figure 3, be arranged in the state at non-black receiving position place at the first black receiving element 13, the diapire 14a of the second black receiving element 14 constitutes has following size, this size makes: when the direction that forms surface crosswise with nozzle is seen, and diapire 14a the is overlapping whole diapire 13a of the first black receiving element 13.Therefore, the first black receiving element 13 and the second black receiving element 14 that is positioned at non-black receiving position place arranged compactly along the depth direction (direction of arrow D) of imaging device 1.Therefore, can reduce the size of this imaging device 1.
In addition, as shown in Figure 5, in the diapire 14a of the second black receiving element 14, form the connecting hole 70 that passes diapire 14a.These connecting holes 70 import the useless ink container 6 by managing 11 China inks that will flow to from the diapire 13a of the first black receiving element 13 on the diapire 14a of the second black receiving element 14.
As shown in Figure 5, connecting hole 70 be arranged in diapire 14a on the front on the direction of guide rod 20, and be arranged on the extended line of groove 60 of the first black receiving element 13 that moves to black receiving position.At this moment, the end that is positioned on the non-black receiving position side that has moved to the first black receiving element 13 of black receiving position is positioned at connecting hole 70 tops.By connecting hole 70 is arranged in those positions,, the groove 60 by the first black receiving element 13 can directly flow in the connecting hole 70 thereby flowing to the part of the China ink of the second black receiving element 14.Therefore, China ink can be imported to rapidly in the connecting hole 70.In addition, as shown in Figure 4, because diapire 14a is downward-sloping towards connecting hole 70, so the China ink on the diapire 14a can import in the connecting hole 70 reposefully.
In addition, as shown in Figure 5, in diapire 14a, form groove 71, these grooves 71 from connecting hole 70 along guide rod 20 bearing of trend substantial linear extend, and from the surface depression of diapire 14a.The China ink that groove 71 will flow on the diapire 14a imports in the connecting hole 70.The same with the groove 60 in being formed on the first black receiving element 13, each groove 71 its cross section in these grooves 71 are roughly V-arrangement.Therefore, China ink can import in the connecting hole 70 reposefully.
In addition, the zone except groove 71 and connecting hole 70 of the diapire 14a of the second black receiving element 14 is coated with waterproofing membrane.That is to say that this zone has than the regional good water proofing property that forms groove 71 and connecting hole 70.Therefore, the China ink that flows among the diapire 14a of the second black receiving element 14 can be collected in rapidly in groove 71 and the connecting hole 70.Therefore, can discharge China ink rapidly.
Thereby except the first black receiving element 13, the second black receiving element 14 also constitutes like this and arranges.For example,, then it is contemplated that, in the first black receiving element 14, the blotting member is set so that be absorbed in the China ink that goes out from nozzle ejection in the cleaning operation if the second black receiving element 14 is not set.But, in this case, because the China ink that is absorbed has increased the weight of blotting member, so the movement velocity of the first black receiving element 13 will reduce.Therefore, cleaning operation can be not carry out at a high speed.In order to solve the problem that in above situation, produces, it is also contemplated that pipe is connected on the first black receiving element, and can China ink directly be discharged to useless ink container 6 from this pipe.But, in this case, because the first black receiving element 13 constitutes reciprocating motion, so the pipe that connects may disconnect.On the contrary, because the second fixing black receiving element 14 is provided, so the China ink that is ejected on the first black receiving element 13 flows to the second black receiving element.Therefore, can prevent the problems referred to above.
According to above structure, China ink is formed with the connecting hole 70 that is communicated with the useless ink container 6 with larger capacity from the surface of the second black receiving element 14 that the first black receiving element 13 flows into.
In addition, the top edge of the sidewall 14b of the second black receiving element 14 is as the track of wheel 33 rollings.Because this structure has been eliminated necessity that other track is set, so can reduce the number of components of this imaging device 1.
Then the electrical structure of this imaging device 1 is described with reference to Figure 12.Figure 12 is a block diagram, demonstrates the electrical structure of this imaging device 1.
One chip microcomputer (CPU) 80, ROM81, RAM82, gate array (G/A) 83, head driver 84 etc. are installed on imaging device 1.And CPU80, ROM81, RAM82, gate array 83 and head driver 84 interconnect by address bus 85 and data/address bus 86.
