External force FP1 (Figure 25) is from the device side terminal group 799 of contact mechanism 70A to the contact portion cp of circuit substrate 400 The external force (active force) of application.External force FP1 is the power of +Y direction.External force FP2 (Figure 24) be because liquid supply needle 640A, 640B, 640C above pushes away valve body 286 to +Z direction side and force application part 285 is made to compress the external force (reaction force) generated in turn.External force FP2 For the power of +Z direction.External force FP3 (Figure 25) is flexible deformation due to liquid supply needle 640A, 640B, 640C of sealing 287, from And the external force generated by the reaction force of flexible deformation.External force FP3 is along the X/Y plane parallel with X-direction and Y-direction Power.By external force FP1~external force FP3, even if second container 20 is in the state of being installed on the second mounting portion 602T, it is also possible to It moves to a certain extent.

In addition, in the case where bracket 520 is located at place of turning back (the switching place of moving direction) of moving direction, bracket 520 acceleration or deceleration becomes larger, and second container 20 generates inertia force big as caused by acceleration and deceleration.By the inertia force, Turning moment MXZ, MXY1, MXY2 are generated in second container 20.

By turning moment MXZ (Figure 24), second container 20 is supplied with liquid supply needle 640A, 640B, 640C to liquid Centered on the insertion position of mouth 280A, 280B, 280C, in the direction DXZ along the XZ plane parallel with X-direction and Z-direction It shakes.The movement of second container 20 as caused by turning moment MXZ is (strictly speaking, from liquid supply port 280A, 280B, 280C The contact site of liquid supply needle 640 and the sealing 287 of valve system 284) it is more remote bigger.In addition, passing through turning moment MXY2 (Figure 25), second container 20 is centered near central axis CC, along the X/Y plane parallel with X-direction and Y-direction Direction DXY2 on rotate.In addition, 204 side of first side of second container 20 is by turning moment MXY1 (Figure 25) with center Centered near axis CC, rotated on the direction DXY1 along the X/Y plane parallel with X-direction and Y-direction.By turning moment The the movement of second container 20 caused by MXY1, MXY2 the remote bigger from central axis CC.In addition, with three central axis CM, The moving in rotation of XZ plane or X/Y plane centered on CC, CN or shake can also be considered as centered on the first central axis CC Moving in rotation or shake.This is because during the first central axis CC is located in the X-direction of three central axis CM, CC, CN Centre.

It is identical as second container 20, it also can produce the effect or turning moment of external force FP1~FP3 in the first container 10 MXZ,MXY1,MXY2.But since second container 20 is the container for accommodating a variety of inks, there are weight ratio the first containers 10 big tendencies.Therefore, second container 20 significantly bears the inertia force generated by the acceleration and deceleration of bracket 520, and rotates Torque MXZ, MXY1, MXY2 also become larger.That is, second container 20 is possible to substantially move with the reciprocating action of bracket 520.? In second container 20, in order to suitably maintain device side terminal group 799 with the contact of contact portion cp, need with the first container 10 not Same means.

A-8. the movement about limitation second container 20:

A-8-1. about external force FP2 and turning moment MXZ

Figure 26 be for illustrating in order to limit second container 20 movement structure figure.Figure 27 is for illustrating limitation The figure of the movement of the X-direction of two containers 20.

As shown in figure 26, under the installation condition of second container 20,235 (strictly speaking, container side card of container side holding section The face of the upside in conjunction portion 235) engaging in device side holding section 632A downside face 633.As a result, for example, can reduce because outer The movement of second container 20 caused by the influence of power FP2 or turning moment MXZ (Figure 24).Thereby, it is possible to reduce circuit substrate 400 Contact portion cp relative to device side terminal group 799 position variation, therefore connecing for circuit substrate 400 can be well maintained The contact of contact portion cp and device side terminal group 799.

By configuring contact portion cp in second side 203 apart from 201 side of bottom surface than the position closer apart from top surface 202 It sets, i.e., at the position of liquid supply port 280A, 280B, 280C, so that turning moment MXZ shown in Figure 24 can also be inhibited It is influenced caused by variation the position of contact portion cp.As described above, the movement of the second container 20 as caused by turning moment MXZ From liquid supply port 280A, 280B, 280C (strictly speaking, contact of liquid supply needle 640 and the sealing 287 of valve system 284 Position) it is more remote bigger.Contact portion cp is positioned close to the position of liquid supply port 280A, 280B, 280C.Therefore, though Second container 20 is centered on central axis CM, CC, CN, in the direction DXY2 along the X/Y plane parallel with X-direction and Y-direction In the case where upper rotation, it can also reduce the variation of the position of contact portion cp.

In the present embodiment, as shown in figure 23, in the X direction, a part of multiple contact portion cp is located at container side card In range WE locating for conjunction portion 235.That is, in the X direction, range WE is Chong Die in a part with range WA.In addition, engaging center CE It is arranged between the first median plane PC and the second median plane PN.By these structures, turning moment MXZ is also able to suppress to contact It is influenced caused by the variation of the position of portion cp.About its reason, it is illustrated following with Figure 24.

The part that second side 203, third side 205, top surface 202 are intersected is as corner L3.By second side 203, The part that 4th side 206, top surface 202 are intersected is as corner R3.When it is assumed that second container 20 does not have engaging part 230, The turning moment MXZ generated due to 520 acceleration and deceleration of bracket is roughly the same on corner R3 and corner L3.When bracket 520 is in the side-X When turning back to side, the anticlockwise turning moment MR3 in Figure 24 in turning moment MXZ is applied to corner R3 (the first feelings Condition).In addition, the clockwise rotary force in Figure 24 when bracket 520 is when +X direction side is turned back, in turning moment MXZ Square ML3 is applied to corner L3 (the second situation).The size of turning moment MR3 and the size of turning moment ML3 are roughly the same.It is another Aspect as above utilizes described in Fig. 9, under the first container 10 and the installation condition of second container 20, in the X direction, second container 20 is bigger than the first container 10 and the interval D 2 of second container 20 with the interval D 1 of pan straddle 60.Therefore, pass through turning moment MR3 And the space ratio that corner R3 can be made to rotate to 606 side of the 4th device side sidewall portion can make corner by turning moment ML3 L3 is big to the space that sidewall portion 605 side in 3rd device side rotates.Therefore, corner R3 is possible to more significantly move than corner L3. In the present embodiment, as described above, engaging center CE is arranged between the first median plane PC and the second median plane PN.That is, card Conjunction center CE is located at apart from the farther position corner R3.Therefore, the corner as caused by turning moment MR3 can more effectively be limited The movement of R3.

As shown in figure 23, by being located at a part of multiple contact portion cp in the X direction locating for container side holding section 235 Range WE in, the variation in the XZ plane of the position of contact portion cp as caused by turning moment MXZ can be reduced.Therefore, energy Enough it is well maintained the contact of contact portion cp with device side terminal group 799.

As shown in figure 26, second container 20 is because of the external force FP2 by +Z direction, with liquid supply port 280A, 280B, 280C Centered on, it is rotated to the direction arrow RYZ.The rotation in direction shown in arrow RYZ refers to, along parallel with Y-direction and Z-direction The rotation of YZ plane.In addition, the lower part that the rotation in direction shown in arrow RYZ is second side 203 is promoted to +Z direction, first The rotation that the top of side 204 declines to -Z direction.When second container 20 is rotated to the direction arrow RYZ, protrusion 262,263 with Device side bottom wall part 601 abuts.Second container 20 is restricted to the rotation in the direction arrow RYZ as a result,.As shown in figure 16, it dashes forward 262,263 are played across the side of the central axis CC and the plane PCP vertical with X-direction of the liquid supply port 280B comprising center There are two formula settings.Thereby, it is possible to more reliably limit rotation of the second container 20 to the direction arrow RYZ.

As shown in figure 16, three liquid supply port 280A, 280B, 280C configurations are on the straight line parallel with X-direction. Even if second container 20 is rotated to the direction arrow RYZ shown in Figure 26 as a result, can also prevent liquid supply needle 640A, 640B, 640C changes to the degree of intrusion of three liquid supply ports 280A, 280B, 280C, the position of intrusion because of each supply mouth. Therefore, it can be well maintained the connection of liquid supply port 280A, 280B, 280C and liquid supply needle 640A, 640B, 640C, The intrusion of the leakage or air of liquid to liquid supply needle 640A, 640B, 640C can be reduced.

A-8-2. about external force FP1, FP3

As shown in figure 26, the external force for being applied to the +Y direction in the external force of the Y-direction of second container 20 is external force FP1 and outer Power FP3, the external force of -Y direction are only external force FP3.Therefore, second container 20 has and is significantly born compared with -Y direction to the side+Y To the tendency of the influence of the external force of application, to height a possibility that +Y direction movement.In the present embodiment, in second container 20 Limitation protrusion 282 (Figure 14) and dress under installation condition, positioned at the position for more leaning on +Y direction side than central liquid supply mouth 280B Set the abutting of lateral confinement wall portion 615.Thereby, it is possible to limit movement of the second container 20 to +Y direction side.Therefore, it can tie up well Hold the contact portion cp of circuit substrate 400 and the contact of device side terminal group 799.

As shown in figure 23, external force FP1 and outer can also be inhibited by intersecting central contact portion cpc with the first median plane PC It is influenced caused by variation of the power FP3 the position of contact portion cp.Intersected by central contact portion cpc with the first median plane PC, such as Shown in Figure 26, multiple contact portion cp can be clamped by central liquid supply mouth 280B and device side terminal group 799.As a result, can Enough reduce the movement of contact portion cp release unit side subgroup 799.Therefore, the contact of circuit substrate 400 can be well maintained The contact of portion cp and device side terminal group 799.

As shown in figure 27, liquid supply port 280A, 280B, the 280C's generated by the component of the X-direction in external force FP3 The movement of X-direction can by make peripheral parts 283A, 283B, 283C and device side limit wall portion 615 it is opposite in the X direction and It is limited.In the case where liquid supply port 280A, 280B, 280C are intended to mobile to X-direction, peripheral parts 283A, 283B, 283C is abutted with device side limitation wall portion 615.The movement of second container 20 in X direction as a result, is restricted.

A-8-3. about turning moment MXY1, MXY2

The influence of turning moment MXY2 shown in Figure 25 can be inhibited in the following manner: by liquid supply port Distance second side 203 ratio configured with contact portion cp of 280A, 280B, 280C configuration on bottom surface 201 is apart from first side 204 closer proximity.As described above, by the movement of the turning moment MXY2 second container 20 generated from central axis CM, CC, CN It is more remote bigger.Contact portion cp is positioned close to the position of central axis CM, CC, CN of liquid supply port 280A, 280B, 280C It sets.Therefore, even if in second container 20 centered on central axis CM, CC, CN, along the XY parallel with X-direction and Y-direction In the case where rotating on the direction DXY2 of plane, it can also reduce the variation of the position of contact portion cp.

The influence of turning moment MXY1 shown in Figure 25 can be inhibited in the following manner: be arranged in bottom surface 201 On, apart from first side 204 than insertion apparatus pleurapophysis in the recess portion 264 (Figure 14) apart from 203 closer proximity of second side Play 638 (Fig. 3, Fig. 5).That is, being inserted into recess portion 264 by device lateral process 638, second container 20 can be limited to direction The movement of DXY1.In addition, it is mobile to direction DXY1 since second container 20 can be limited, it can also limit second side The movement of the direction DXY2 of 203 sides.Therefore, it is able to suppress the variation of the position of contact portion cp, contact portion can be well maintained The contact of cp and device side terminal group 799.

As shown in figure 23, central contact portion cpc does not intersect with the second median plane PN or third median plane PL, with One median plane PC intersection.Thereby, it is possible to reduce the influence of turning moment MXY1 shown in Figure 25.Hereinafter, to central contact portion cpc Position and Figure 25 shown in turning moment MXY1 influence between relationship be described in more detail.

Figure 28 is the schematic diagram for indicating the second container 20V of the first reference example.Figure 29 is the second reference for indicating reference example The schematic diagram of the second container 20W of example.The difference of the second container 20 of second container 20V, 20W and present embodiment of reference example Point is allocation position of the circuit substrate 400 in second side 203.In the second container 20V shown in Figure 28, circuit substrate The position of 400 deviation +X direction sides of the configuration in second side 203, in the central contact portion cpc of circuit substrate 400 and second Heart face PN intersection.In second container 20W (Figure 29), circuit substrate 400 configures the deviation -X direction side in second side 203 Position, the central contact portion cpc of circuit substrate 400 intersects with third median plane PL.

As shown in figure 28, it is configured the case where being biased to the position of 205 side of third side (+X direction side) in circuit substrate 400 Under, when bracket 520 accelerates mobile to +X direction, in corner, the part of R1 generates big turning moment MXY1t.Pass through the rotation Torque MXY1t, second container 20V will substantially be rotated to direction shown in arrow DXY1t.Moreover, near circuit substrate 400 It will substantially be rotated to direction shown in arrow DXY2t.That is, the variation of the position of the contact portion cp on circuit substrate 400 becomes larger.

As shown in figure 29, it is configured the case where being biased to the position of 206 side of the 4th side (-X direction side) in circuit substrate 400 Under, when bracket 520 accelerates mobile to -X direction, in corner, the part of L1 generates big turning moment MXY1w.Pass through the rotation Torque MXY1w, second container 20W will substantially be rotated to direction shown in arrow DXY1w.Moreover, near circuit substrate 400 It will substantially be rotated to direction shown in arrow DXY2w.That is, the variation of the position of the contact portion cp on circuit substrate 400 becomes larger.

On the other hand, present embodiment as shown in figure 25, when with central contact portion cpc be not with the second median plane PN or Third median plane PL intersection, but when circuit substrate 400 is set with the first median plane PC mode intersected, in bracket 520 to+X When direction accelerates mobile, when accelerating mobile to -X direction, corner R1, R2 of second container 20 can generate the rotation of same degree Torque MXY1.Turning moment MXY1w shown in turning moment MXY1t and Figure 29 shown in turning moment MXY1 ratio Figure 28 It is small.Therefore, the contact portion cp in the second container of present embodiment 20, when bracket 520 can be made to accelerate mobile to +X direction Position variation it is smaller than second container 20V.In addition, can make contact portion cp of the bracket 520 to -X direction acceleration when mobile The variation of position is smaller than second container 20W.Thereby, it is possible to be well maintained the contact portion cp of circuit substrate 400 and device side The contact of subgroup 799.

A-9. the effect of container suite and liquid injection system:

According to above embodiment, by making second container 20 accommodate a variety of (being in the present embodiment three kinds) liquid, Compared with every kind of container for accommodating plurality of liquid is respectively set, container suite 5 or liquid injection system 90 can be made small-sized Change.In addition, the second container 20 of plurality of liquid is accommodated by replacement, with the case where replacement accommodates the container of various liquid respectively phase Than can reduce time energy, the frequency of replacement.In addition, container suite 5 has the straight liquid type for not accommodating liquid absorbent material 299 The first container 10 and accommodate liquid absorbent material 299 liquid absorption figure second container 20.By utilizing two types Container, can apply flexibly that structure is simple and the slightly complicated straight liquid for being but suitble to high speed printing of liquid absorption figure and structure of low price The advantages of both types.

In the present embodiment, the first container 10 is straight liquid type container.Therefore, even if the liquid of the first container 10 is high In the case where fastly supplying to print head 540, the inflow of bubble can be also reduced, so as to successfully spray from print head 540 Penetrate liquid.On the other hand, second container 20 is the container of liquid absorption figure.Therefore, when by the liquid at high speed of second container 20 When ground is supplied to print head 540, the flowing of the ink in liquid absorbent material 299 does not catch up with the feed speed of ink, can to have The layer of the ink in liquid absorbent material 299 can be caused to be cut off by air.It is thereby possible to cause not supply to 540 side of print head And the amount (amount of unused ink) of the ink remained in liquid absorbent material 299 increases.In addition, since ink is in liquid absorbent material Flowing in 299 is cut off by air, and it is therefore possible to cause bubble to flow into print head 540.In the present embodiment, it accommodates black The first container 10 of the straight liquid type of chromatic ink is used in high speed printing and when low speed prints, and the liquid for accommodating color inks is inhaled The second container 20 of acceptor type is only used when low speed prints.Thereby, it is possible to carry out the high speed printing using black ink, and The amount of unused ink of second container 20 can be reduced.In addition, due to can reduce bubble from second container 20 to 540 row of print head Out a possibility that, therefore also it is able to suppress the reduction of printing quality.

In addition, pan straddle 60 has the first mounting portion 602W and the second mounting portion 602T according to above embodiment. That is, since the liquid injection system 90 of present embodiment is to be separately mounted to specifically install with two kinds of container 10,20 It is constituted premised on portion 602W, 602T, therefore is able to suppress liquid injection apparatus 50 structure is complicated and change.

In addition, accommodating the ink (pigment inks containing pigment in the first container 10 of straight liquid type according to above embodiment Water), dye ink is accommodated in the second container 20 of liquid absorption figure.Pigment is easy sedimentation, but not due to the first container 10 Accommodate liquid absorbent material, therefore even if in the case where pigment sedimentation, also can by apply to the first container 10 vibrate and Easily disperse pigment.Due to using dye ink in the second container 20 of liquid absorption figure, will not generate such as The problem of being settled as ink containing pigment.Thereby, it is possible to reduce the concentration of the ink sprayed from liquid injection apparatus 50 A possibility that generating deviation.In addition, paint ink is set as by the black ink that will be received in the first container 10, in Xiang Putong In the case that paper prints, it can be more difficult to ooze out than dye ink.On the other hand, the coloured silk by will be received in second container 20 Chromatic ink is set as dye ink, can be improved to the colour rendering in the case where the printing of special paper.That is, according to the present embodiment, it is black It is white be printed in plain paper at high speed implement, colored printing implement to low speed on special paper, thus, it is possible to cope with a variety of printings.

In addition, spraying the compared with second injection oral area 544A, 544B, 544C of the liquid of injection second container 20 The maximum injection quantity that can be sprayed per unit time of the first injection oral area 544D of the liquid of one container 10 is more (Fig. 8). Thereby, it is possible to the ink of the first container 10 is used in high speed printing.In addition, due to using second container when low speed prints 20, therefore a possibility that the flowing that can reduce the ink in liquid absorbent material 299 is cut off by air.
