Now, helical spring 132 pushes down on contact member 131.When helical spring 132 has natural length, contact member 131 Surface 133,134 is located at the lower section of recess 129.That is, by the compression and expansion of helical spring 132, contact member 131 can be Moved on above-below direction 53 and 54.

Although not shown in the drawings, inner frame 35 is formed generally annular shape, and on left and right directions 55 and 56 A contralateral surface open wide.The surface unlimited accordingly of inner frame 35 is sealed with framework 35 internally with film (not shown) Form the ink chamber 36 for storing ink.Inner frame 35 includes the antetheca 40 for limiting a part for ink chamber 36.Work as interior sash When frame 35 is accommodated in protecgulum 32, antetheca 40 faces the antetheca 140 of protecgulum 32.More specifically, when inner frame 35 is received When in protecgulum 32, the preceding surface of antetheca 40 faces the rear surface (relative with preceding surface) of antetheca 140.Ink supply 34 is arranged on At antetheca 40.

As shown in fig. 6, ink supply 34 (example of supply department) protrudes forward from the antetheca 40 of inner frame 35.Ink supply 34 With cylindrical shape, and it is outstanding by forming the through hole 97 in the antetheca 140 of protecgulum 32.That is, ink supply 34 In the lower end of antetheca 140.

Ink supply 34 is included in circular cylindrical tubular wall 73, containment member 76 and the cap that inner space is limited in the ink supply 34 79.Containment member 76 and cap 79 are attached to tubular wall 73.

Tubular wall 73 extends to connect the inside and outside of ink chamber 36.Tubular wall 73 has what is opened wide in ink chamber 36 Rear end.Tubular wall 73 has the front end to the external open of print cartridge 30.Therefore, tubular wall 73 is empty by the inside of the tubular wall 73 Between provide fluid communication between the outside of ink chamber 36 and print cartridge 30.Therefore, ink supply 34 can will be stored in ink chamber 36 In ink the outside of print cartridge 30 is fed to by the inner space of tubular wall 73.Containment member 76 and cap 79 are attached to tubular wall 73 front end.

Valve 77 and helical spring 78 are accommodated in the inner space of tubular wall 73.Valve 77 and helical spring 78 are used as making ink supply The state in portion 34 figure 9 illustrates state and Fig. 6 in optionally switch between the state that shows.That is, figure 9 illustrates Under state, it is allowed to which ink flows out ink chamber 36 to the outside of print cartridge 30 by the inner space of tubular wall 73.Figure 6 illustrates shape Under state, the inner space to the outside of print cartridge 30 of ink outflow tubular wall 73 is not allowed.

Valve 77 can move to be formed at the center of containment member 76 to open and close on fore-and-aft direction 51 and 52 Ink supply port 71.Helical spring 78 is by the biased forward of valve 77.Therefore, in the case of no application external force, valve 77 closes sealing structure The ink supply port 71 of part 76.

Containment member 76 is attached to the front end of tubular wall 73.Containment member 76 is by elastomeric material (such as rubber or elasticity Body) formed.Containment member 76 is disc shaped and has the central portion for being formed with through hole.Through hole is in the He of fore-and-aft direction 51 On 52 through containment member 76 central portion with provide limit ink supply port 71 tubulose inner peripheral surface.Ink supply port 71, which has, to be slightly less than The diameter of the external diameter of tattooing needle 102.In the case where containment member 76 is attached to the front end of tubular wall 73, the fit on of cap 79 to tubulose Wall 73 so that the front end fluid-tight contact of containment member 76 and tubular wall 73.

In the state of valve 77 closes ink supply port 71, when print cartridge 30 is inserted into box attachment 110, tattooing needle 102 enters In ink supply port 71.While containment member 76 is resiliently deformed, the outer surface of tattooing needle 102 is with limiting the interior of ink supply port 71 Perimeter surface contacts, to provide and limit the liquid-tight seal of the inner peripheral surface of ink supply port 71.When the terminal part of tattooing needle 102 is moved through When in the inner space of containment member 76 and entrance tubular wall 73, tattooing needle 102 contacts with valve 77.As print cartridge 30 is further inserted Enter in box attachment 110, tattooing needle 102 makes valve 77 overcome the bias force of helical spring 78 and be moved rearwards, so as to open ink supply port 71.Therefore, the ink being stored in ink chamber 36 can flow to the terminal part of tattooing needle 102 by the inner space of tubular wall 73 In.Although not shown in the drawings, flow therethrough of the ink from the inner space of tubular wall 73 by formation in the terminal part of tattooing needle 102 Into the inner space of tattooing needle 102.Therefore, black inner space that can be by tubular wall 36 and the ink being stored in ink chamber 36 Pin 102 flow to the outside of print cartridge 30.

Ink supply 34 can be not provided with the valve 77 for closing ink supply port 71.Alternatively, for example, ink supply port 71 can use film Close.In this case, when print cartridge 30 is inserted into box attachment 110, tattooing needle 102 can stab out the film, thus allow ink The terminal part of pin 102 enters the inside of the inner space of tubular wall 73 by ink supply port 71.Still alternatively, ink supply port 71 can lead to The elastic force for crossing containment member 76 itself is closed.In this case, only when tattooing needle 102 is inserted into ink supply port 71, ink supply port 71 can be pushed and expanded by tattooing needle 102.

Surplus test section 58 is configured to be changed from print cartridge 30 according to the state (that is, remaining ink amount in print cartridge 30) of print cartridge 30 The state of light that is sent (that is, from the headroom sensor 103 of box attachment 110) of outside.

As shown in fig. 6, surplus test section 58 includes outer cover 62 and sensor arm 59.

The upper wall of outer cover 62 from inner frame 35 projects upwards.Outer cover 62 is exposed by forming the through hole 98 in protecgulum 32 To outside so that outer cover 62 projects upwards relative to the roof 141 of protecgulum 32.Restriction connects interior with ink chamber 36 in outer cover 62 Portion space.Outer cover 62 can allow for light to pass through on left and right directions 55 and 56.That is, outer cover 62 has translucency.

Sensor arm 59 is arranged in the ink chamber 36 of inner frame 35.Sensor arm 59 is by left and right directions 55 and 56 The pivot 61 of upper extension supports.Sensor arm 59 can be pivotally displaced around pivot 61.Sensor arm 59 includes float 63 and the Two light barriers 66.

Float 63 has the proportion smaller than the black proportion being stored in ink chamber 36.Therefore, in ink chamber 36, as long as Float 63 is in ink, and buoyancy is just produced on float 63.In other words, in the state of ink chamber 36 is almost full with ink, sensing Device arm 59 is promoted to be pivotally displaced in counter clockwise direction in figure 6 due to the caused buoyancy on float 63.Hereafter In, it is assumed that ink chamber 36 assumes sensor arm 59 in the posture that the solid line in by Fig. 6 represents full of ink.

Second light barrier 66 is plate shape.Second light barrier 66 is arranged in the outer cover 62 of inner frame 35.Specifically, The position of second light barrier 66 will height relative to the roof 141 of protecgulum 32.Because sensor arm 59 is promoted with counterclockwise in figure 6 It is pivotally displaced, the wall of front end of second light barrier 66 with limiting outer cover 62 contacts.Due to the contact, sensor arm 59 is kept The posture that solid line in by Fig. 6 represents.Figure 6 illustrates in the state of, the second light barrier 66, which stops, comes from headroom sensor 103 light is advanced through outer cover 62 on left and right directions 55 and 56.Now the position of the second light barrier 66 is referred to as test position (being represented by the solid line in Fig. 6).

More specifically, when the light sent from the light emission part of headroom sensor 103 incides before light receiver is reached When on the second light barrier 66, the intensity of the light received at light receiver is less than predetermined strength, e.g. zero.Pay attention to second gear Tabula rasa 66 can be blocked in the light advanced on left and right directions 55 and 56 completely, and can partly decay light, can reflect light to change Its direct of travel, or can be with fully reflective light.

When the ink amount reduction in ink chamber 36 and the liquid level of ink are got lower than by the float 63 of the solid line expression in Fig. 6 Position (when sensor arm 59 is in the position of the float 63 when the second light barrier 66 stops that light travels across the posture of outer cover 62) When, decline with the liquid level of inking, float 63 starts to move down.With moving down for float 63, sensor arm 59 is in figure 6 It is pivotally displaced clockwise, so as to which a part for the second light barrier 66 in outer cover 62 is removed by from headroom sensor 103 Light emission part advances to the light path that the light of light receiver is formed.Therefore, received at the light receiver of headroom sensor 103 The intensity of light is equal to or more than predetermined strength.Now the position (position represented by the dotted line in Fig. 6) of the second light barrier 66 is The non-detection position different from test position.

Next, it will describe to be used for the process that print cartridge 30 is attached to box attachment 110.

As shown in fig. 7, before print cartridge 30 is inserted into box attachment 110, valve 77 closes the ink supply port 71 of containment member 76. Therefore, now, the ink flowing from ink chamber 36 to the outside of print cartridge 30 is interrupted.

In addition, as shown in FIG. 7, before print cartridge 30 is attached to box attachment 110, thing is not in surplus biography Between the light emission part and light receiver of sensor 103.Therefore, headroom sensor 103 exports high electricity to the controller of printer 10 Ordinary mail number.Similarly, since thing is not between the light emission part and light receiver of attachment of sensors 113, attachment of sensors 113 export high level signal to the controller of printer 10.

As shown in fig. 7, in the print cartridge 30 being attached to before box attachment 110, movable member 80 is conducted oneself with dignity due to it It is pivotally displaced on the direction represented by arrow 89.Therefore, movable member 80 is in prime.

In order to be attached print cartridge 30, print cartridge 30 is inserted in the shell 101 of box attachment 110 by opening 112, in Fig. 7 It is shown.Now, while antetheca 140 (the preceding surface of antetheca 140) face forward, print cartridge 30 is inserted into box attachment 110. The rear being located relative to due to the top 41U of the rear wall 41 of bonnet 31 for the bottom 41L of rear wall 41, i.e., due to top 41U Nearer from user than bottom 41L from user, user can push top 41U so that print cartridge 30 is forwardly inserted into box attachment In 110.

As noted previously, as prompting the sheet material for being attached to top 41U that user pushes top 41U (for example, such as The symbol of the text of " PUSH ", such as arrow or the figure of explanation finger press), user is encouraged to push top 41U. When print cartridge 30 is inserted into the shell 101 of box attachment 110, the bottom of print cartridge 30, i.e. inserted the bottom of protecgulum 32 and bonnet 32 Enter to be formed in lower guiding groove 109 corresponding in shell 101.

In addition, once print cartridge 30 is inserted into the shell 101 of box attachment 110, the surface 133 of contact member 131 with The rear end in contact of the bottom wall of shell 101.Therefore, surface 133 is configured the bottom wall of shell 101 and pressed upwards on.Therefore, contact member 131 overcome the bias force of helical spring 132 to move up to be received in recess 129.As shown in fig. 7, the quilt of contact member 131 The bottom wall of shell 101 supports from below.

The state shown with print cartridge 30 from Fig. 7 is inserted further along, and print cartridge 30 reaches the state shown in Fig. 8. Now, as shown in figure 8, the cap 79 of ink supply 34 is initially entered in guide portion 105.

In addition, as shown in figure 8, bar 125 faces the recess 96 of protecgulum 32 and is moved to by opening 96A in recess 96. Another surface 84 of the bar 125 come into recess 96 and the movable member 80 in prime connects from its front side Touch, so as to extrude movable member 80 backward.Therefore, movable member 80 is pivotally moved on the direction that arrow 88 represents It is dynamic.That is, movable member 80 is pivotally displaced from prime towards second.

Specifically, first, bar 125 contacts the first flat surface 161.When print cartridge 30 is inserted further along, bar 125 with First flat surface 161 is separated and contacted with inclined surface 163, and is drawn along inclined surface 163 towards the second flat surface 162 Lead.When print cartridge 30 is inserted further along, bar 125 is separated with inclined surface 163 and contacted with the second flat surface 162 (state shown in Fig. 8).When print cartridge 30 is inserted further along, bar 125 separates with the second flat surface 162, so as to again It is secondary to be contacted with inclined surface 163, and guided along inclined surface 163 towards the first flat surface 161.When print cartridge 30 is entered one again When step is forwardly inserted, bar 125 separates and contacted from below with the first flat surface 161 flat with support first with inclined surface 163 Surface 161 (state shown in Fig. 9).Now, movable member 80 is in second.

In addition, figure 8 illustrates in the state of, the first light barrier 67 is located at the light emission part and light of headroom sensor 103 Between acceptance division.Therefore, headroom sensor 103 exports low level signal to the controller of printer 10 rather than high level is believed Number.That is, the signal exported from headroom sensor 103 is changed into low level from high level.On the other hand, attachment of sensors 113 continues High level signal is exported to the controller of printer 10.

The state shown with print cartridge 30 from Fig. 8 is inserted further along, and print cartridge 30 reaches the state shown in Fig. 9.Such as Shown in Fig. 9, the cap 79 of ink supply 34 is had been introduced into guide portion 105, and tattooing needle 102 has overcome the bias force of helical spring 78 Ink supply port 71 is moved through so that valve 77 to be separated from containment member 76.Therefore print cartridge 30 is applied in the biasing of helical spring 78 Power, print cartridge 30 is promoted backward by the bias force.

In addition, now, the basal surface 85A downwards of the first protuberance 85 is configured the shell 101 of box attachment 110 Surface 170 support, surface 170 towards top and positioned at guide portion 105 top.Due to basal surface 85A and surface 170 it Between this contact, print cartridge 30 fixes position on above-below direction 53 and 54.Incidentally, basal surface 85A be arranged to when from Observe overlapping with IC plates 64 during print cartridge 30 in top.That is, basal surface 85A has what is be aligned on above-below direction 53 and 54 with IC plates 64 Part.Alternatively, it can be used for the print cartridge 30 of support attachment instead of surface 170, such as bar 125, to provide print cartridge 30 upper and lower Positioning on direction 53 and 54.

As described above, movable member 80 is extruded by bar 125 and is pivotally moved to second.Now, bar 125 Top surface 125A supports movable member 80 (specifically, first flat surface 161 on another surface 84) from below.In addition, this When, IC plates 64 have arrived at the lower section of contact 106 and contacted from below with contact 106.By this way, electrode 65 electrically connects Make 106 upward elastic deformation of contact simultaneously to contact 106.That is, when movable member 80 is in second, the electricity of print cartridge 30 Pole 65 can be electrically accessed the contact 106 of box attachment 110.Now, the contact 106 that IC plates 64 are elastically deformed pushes down on. However, because bar 125 supports movable member 80 from below, so IC plates 64 can be precisely located relative to contact 106.

In addition, in the state of Fig. 9 is shown, the second light barrier 66 is located at the light emission part of headroom sensor 103 and light connects Between receipts portion.Therefore, the signal exported from headroom sensor 103 to the controller of printer 10 maintains low level.In addition, the One light barrier 67 is located between the light emission part and light receiver of attachment of sensors 113.From attachment of sensors 113 to printer 10 Controller output signal be changed into low level from high level.Therefore, the controller of printer 10 determines that print cartridge 30 is attached To box attachment 110.

In addition, in the state of Fig. 9 is shown, junction surface 130 is in the vertical positioned at the top of corresponding recess 91.That is, connect Touch the bottom wall supports that component 131 is no longer configured the shell 101 of box attachment 110.Therefore, as shown in Figure 10, contact member 131 Move down and be received in recess 91 by the bias force of helical spring 132.Here, because print cartridge 30 is by helical spring 78 bias backward, so the surface 93 of the surface 134 of contact member 131 and recess 91 is from its frontside contacts.That is, contact member 131 surface 134 and the surface 93 of limits recess 91 are engaged with each other.Engagement between surface 134 and surface 93 can limit ink Box 30 is moved rearwards due to the bias force of helical spring 78.That is, print cartridge 30 is fixed relative to the position of box attachment 110, thus Complete print cartridge 30 being attached to box attachment 110.Now, print cartridge 30 is under attached state.

Record first 21 is flowed out to from the print cartridge 30 under attached state and by recording first 21 consumption, be stored in ink with inking Ink amount in chamber 36 is reduced.With the reduction that the ink left in ink chamber 36 is measured, the second light barrier 66 is located in outer cover 62 Be partially moved to from headroom sensor 103 light emission part to light receiver light formed light path skew position.Cause This, the signal exported from headroom sensor 103 is changed into high level from low level.The controller of printer 10 thereby determines that ink chamber Black surplus in 36 diminishes.

Next, the process that will describe to remove from box attachment 100 print cartridge 30 under attached state.

When user grasps and pulls back the print cartridge 30 under attached state, the contact member 131 at junction surface 130 The surface 93 of the recess 91 of extrusion box attachment 110 backward of surface 134.Therefore, contact member 131 passes through from the anti-of surface 93 Active force overcomes the bias force of helical spring 132 to be moved up along surface 93.Therefore, as shown in figure 8, what is had moved up connects Touch component 131 and then by the bottom wall supports for the shell 101 for forming box attachment 110.That is, being moved back for print cartridge 30 is no longer limited It is dynamic.Therefore as user recalls print cartridge 30 backward, it is allowed to which print cartridge 30 moves further back.Print cartridge 30 is finally from box attachment 110 dismountings.

When the print cartridge 30 under attached state is moved rearwards, the first light barrier 67 is also moved rearwards with from attachment of sensors Position skew between 113 light emission part and light receiver.Therefore, from attachment of sensors 113 to the controller of printer 10 The signal of output is changed into high level from low level, so that controller is able to detect that print cartridge 30 from box attachment 110 Dismounting.

When the print cartridge 30 under attached state is moved rearwards, movable member 80 is also moved so as to be positioned in bar 125 Rear.Because bar 125 no longer supports movable member 80, as shown in fig. 7, so movable member 80 focuses on arrow certainly due to it It is pivotally displaced on first 89 direction.That is, movable member 80 is pivotally moved to prime from second.
