The imaginary plane 56 that the jag (front end) that jag (front end) and the China ink of protuberance 76 are measured test section 34 is connected is positioned at the place ahead along direction of insertion 50 of ink supply section 72.In other words, on direction of insertion 50, ink supply section 72 does not extend beyond imaginary plane 56.Therefore, even when print cartridge 30 falls, ink supply section 72 does not directly accept external impact, therefore can protect ink supply section 72 not to be impacted.
Ink-feeding device 100 is arranged in the printer 10.Ink-feeding device 100 is configured to towards record head 21 (seeing Fig. 2) the supply China ink that is arranged in the printer 10.Ink-feeding device 100 comprises box retainer 110, and a plurality of print cartridges 30 can be installed in this box retainer 110.
With reference to figure 3 (A) and 3 (B), box retainer 110 is formed at its inside and holds print cartridge 30.China ink retainer 110 has opening 112 in the front side (left sides among Fig. 3 (A) and 3 (B)) of printer 10.Print cartridge 30 is inserted in the box retainer 110 by opening 112 in the horizontal direction.
With reference to figure 3 (A) and 3 (B), box retainer 110 is provided with sliding component 135.For each print cartridge 30 arranges sliding component 135.Be configured to hold four print cartridges 30 such as compartmentalized box for holding assorted fruits and candies retainer 110, four sliding components 135 that correspond to respectively four print cartridges 30 then are set.
Sliding component 135 is configured to the member that separates with print cartridge 30 and box retainer 110.Sliding component 135 is arranged in the recess 130 of the adjacent end wall 117 of the diapire 132 that is formed on box retainer 110.Opening 129 117 bottom passes end wall 117 in direction of insertion 50 and forms in the end.Recess 130 is continuous with opening 129.Sliding component 135 is formed in the recess 130 along the bottom surface of recess 130 insertion at print cartridge 30/dismounting direction 105 and slides.Sliding component 135 can slide between the position of the surveyed area that leaves fluorescence detector 126 127 as shown in Fig. 3 (A) and the position in surveyed area 127 as shown in Fig. 3 (B).In other words, fluorescence detector 126 is positioned such that the surveyed area 127 of fluorescence detector 126 is positioned at the sliding scale of sliding component 135.
Sliding component 135 is provided with contact site 137, and during being inserted into print cartridge 30 in the box retainer 110, the protruding member 76 of print cartridge 30 contacts with contact site 137.Contact site 137 projects upwards from the main body 136 of sliding component 135.During contact site 137 is located at and is inserted into print cartridge 30 in the box retainer 110 on the course of protuberance 76.
Helical spring 139 is arranged in recess 130.One end of helical spring 139 is connected to the end face 133 of the opening that is positioned at recess 130 112 sides of recess 130.The other end of helical spring 139 is connected to the main body 136 of sliding component 135, so that helical spring 139 is between the main body 136 of the end face 133 of recess 130 and sliding component 135.When helical spring 139 has natural length, namely, when external force was not applied on the sliding component 135, sliding component 135 was positioned to than fluorescence detector 126 more close end faces 133.During being inserted into print cartridge 30 in the box retainer 110, the protruding member 76 pushing contact sites 137 of print cartridge 30.Owing to accept the pressure from protuberance 76, sliding component 135 is mobile in direction of insertion 50, helical spring 139 expansions.When this happens, helical spring 139 is attempted to shorten, so sliding component 135 is being removed the pulling force towards opening 112 of direction 54 acceptance from helical spring 139.Then, when print cartridge 30 arrived the ink supply position, sliding component 135 entered surveyed area 127 to stop the light through surveyed area 127.When sliding component 135 entered surveyed area 127, indirect detection was to the existence of protuberance 76, and the signal of exporting from the light receiver 128 of fluorescence detector 126 changes.By this way, protuberance 76 so that sliding component 135 enters surveyed area 127 and the path of cross-section light in surveyed area 127, comes indirectly-acting in the light by surveyed area 127 by contact and mobile sliding component 135.
With reference to figure 3 (A) and 3 (B), box retainer 110 is provided with locking mechanism 144.When print cartridge 30 during in the ink supply position, the motion of locking mechanism 144 restriction print cartridges 30 on the dismounting direction 54 opposite with direction of insertion 50, and print cartridge 30 is limited in the ink supply position.Locking mechanism 144 be positioned at box retainer 110 in the upper side opposite with fluorescence detector 126 of vertical direction (short transverse 52).In other words, fluorescence detector 126 is positioned at the opposition side of locking mechanism 144.Locking mechanism 144 is positioned at box retainer 110 tops, the opening 112 of adjacent cassettes retainer 110.
With reference to figure 5 (A), when print cartridge 30 when direction of insertion 50 is inserted in the box retainer 110, the end face 44 of rib 43 contacts with the abutting end 146 of locking bar 145.When print cartridge 30 was further inserted into, locking bar 145 pivoted counterclockwise, and abutting end 146 moves up, so that the position of locking bar 145 changes to unlocked position from latched position.The abutting end 146 that has moved up is placed on the upper surface of rib 43.Afterwards, when print cartridge 30 was further inserted into, abutting end 146 slided at the upper surface of rib 43.Then, when abutting end 146 passed through the composition surface 45 of rib 43, locking bar 145 pivoted clockwise, and abutting end 146 moves down (seeing Fig. 6 (A)).
Before print cartridge 30 was inserted into box retainer 110, locking bar 145 was at latched position (seeing Fig. 3 (A)), and the light of fluorescence detector 141 is stopped by the test section 147 of the locking bar 145 in surveyed area 142.Therefore, the signal from fluorescence detector 141 outputs is low level signal (seeing Fig. 8 (A)).When print cartridge 30 is inserted into and locking bar 145 when being pivoted to unlocked position, test section 147 moves to the position outside the surveyed area 142.Therefore, the moment T0 of signal among Fig. 8 (A) from fluorescence detector 141 outputs changes to high level signal from low level signal.
With reference to Fig. 5 (B), when print cartridge 30 is further inserted into, the antetheca 34E of China ink amount test section 34 in Fig. 8 (A) moment T1 and constantly between the T2 through the surveyed area 115 of fluorescence detector 114.Yet, because antetheca 34E is printing opacity, thus from the signal of fluorescence detector 114 outputs among Fig. 8 (A) moment T1 and constantly do not change between the T2 and remain high level signal.
With reference to figure 5 (B), protuberance 76 contacts with the contact site 137 of sliding component 135, and protuberance 76 is at direction of insertion 50 pushing contact sites 137.
When print cartridge 30 was further inserted into, sliding component 135 was accepted from the power of protuberance 76 and beginning mobile in direction of insertion 50.When this happens, helical spring 139 is along with the motion elongation of sliding component 135.Therefore, in helical spring 139, produce the power that helical spring 139 is shunk.The masterpiece that produces in helical spring 139 is used for sliding component 135, as making sliding component 135 in the mobile power of the dismounting direction opposite with direction of insertion 50 54.In other words, sliding component 135 is being removed flexibly pushing on the direction 54 by helical spring 139.
Then, with reference to figure 6 (A), when the ink supply position in the print cartridge 30 arrival box retainers 110, the 34C of exposure section of China ink amount test section 34 is arranged in the surveyed area 115 of fluorescence detector 114.The ink supply position is the position of therein ink tube 122 ink supply of print cartridge 30 can be from black chamber 36 towards box retainer 110, in the present embodiment, is that ink tube 122 inserts position in the through hole 73 of ink supply sections 72 shown in Fig. 6 (A) and 6 (B).When the 34C of exposure section enters surveyed area 115, if scheduled volume or more China ink when being stored in the black chamber 36, that is, and when light barrier 62 when lower position (solid line), light is stopped by the light barrier 62 in surveyed area 115.In this case, the moment T3 of signal among Fig. 8 (A) from fluorescence detector 114 outputs changes to low level signal from high level signal.On the contrary, when the China ink amount in the black chamber 36 during less than scheduled volume, that is, when light barrier 62 when upper position (dotted line), light by surveyed area 115 is not stopped by light barrier 62, so signal remains on high level signal (seeing the dotted line among Fig. 8 (A)).
With reference to figure 6 (A), when print cartridge 30 arrived the ink supply position, the composition surface 45 of rib 43 had passed through the abutting end 146 of locking bar 145.Because abutting end 146 is no longer supported by the upper surface of rib 43, so locking bar 145 pivots clockwise, abutting end 146 moves down and contacts with the upper wall 39 of print cartridge 30.When this happens, the light of fluorescence detector 141 is stopped by the test section 147 at the locking bar 145 of surveyed area 142.Therefore, the moment T5 of signal among Fig. 8 (A) from fluorescence detector 141 outputs changes to low level signal from high level signal.
Next, when by the user when direction of insertion 50 acts on pressure on the print cartridge 30 and removes, the protuberance 76 of print cartridge 30 via sliding component 135 accept from helical spring 139 in the power of removing on the direction 54.With reference to figure 6 (B), the print cartridge 30 that makes capacity is in that to remove direction 54 mobile, and print cartridge 30 is in the corresponding amount in gap of removing between the mobile composition surface 45 with the abutting end 146 that is arranged on locking bar 145 and rib 43 of direction 54.Abutting end 146 and composition surface 45 contact with each other, thereby prevent that print cartridge is in the motion of removing on the direction 54.
On the contrary, with reference to figure 7 (A) and 7 (B), when the print cartridge 30 with fracture protuberance 76 ' when being inserted into box retainer 110, even when print cartridge 30 ' arrival ink supply position, sliding component 135 is not mobile in direction of insertion 50 yet.Therefore, even when print cartridge 30 ' when being installed to box retainer 110, the signal of exporting from the light receiver 128 of fluorescence detector 126 remains high level signal (seeing Fig. 8 (B)) consistently.In other words, the signal of exporting from the light receiver 128 of fluorescence detector 126 does not change.
In the present embodiment because print cartridge 30 ' have a protuberance 76 of fracture, print cartridge 30 ' ink supply section 72 be subject to the impact of external impact.Similarly, if print cartridge 30 ' do not have fully protuberance 76, print cartridge 30 ' ink supply section 72 be subject to the impact of external impact.In this case, the possibility damaged by external impact of ink supply section 72 is high.When print cartridge 30 is installed to box retainer 110 and is used for printer 10, may occur because the ink leakage that the damage of ink supply section 72 causes maybe may occur because China ink can not normally be fed to the record of bad behavior that record head 21 causes from ink supply section 72.And bubble may enter China ink pipe 20 and may gather in the secondary container 28 of record head 21.In this case, when making China ink driven from the actuator (for example, piezoelectric actuator) of nozzle 29 discharges, the power that produces by driven actuator can be absorbed by bubble, and China ink can not discharged from nozzle 29.And, having because actuator is exceedingly driven the situation that causes producing heat, it can cause record head 21 owing to this heat and destroyed problem.In order to reduce this problem, in this embodiment, controller 90 is configured to allow to carry out recording image and cleaning based on the fact that the signal of exporting from the light receiver 128 of fluorescence detector 126 changes printer 10.
With reference to figure 9, controller 90 is configured to control all operations of printer 10.Controller 90 is configured to comprise the microcomputer of CPU91, ROM92, RAM93, EEPROM 94 and ASIC95.
The ROM92 storage program is used for the various operations of CPU91 control printer 12, comprises be used to the program of carrying out the processing shown in Figure 10.RAM93 is used as the storage area of temporary storaging data or signal or the working region that data are processed, and is used for CPU91 and carries out said procedure.The RAM93 storage is as the level (high or low) from fluorescence detector 114,126 and 141 signals of exporting of time series data.Even the setting that the EEPROM94 storage also keeps behind power-off, mark etc.
The analog electrical signal (voltage signal or current signal) of the light intensity that is received by light receiver 128 is depended in light receiver 128 outputs of fluorescence detector 126.Be supplied to controller 90 from the signal of light receiver 128 outputs.Output signal was high level signal when controller 90 determined that level (magnitude of voltage or current value) when signal is more than or equal to the first predetermined threshold, when the level of signal is low level signal during less than the first predetermined threshold.In the present embodiment, when the light of fluorescence detector 126 when surveyed area 127 is blocked, the level of signal is less than the first predetermined threshold, so output signal is confirmed as low level signal.And when not being blocked through the light of surveyed area 127, because the level of signal is more than or equal to the first predetermined threshold, output signal is confirmed as high level signal.
Similarly, the analog electrical signal (voltage signal or current signal) of the light intensity that is received by light receiver is depended in the output of the light receiver of fluorescence detector 141.Be supplied to controller 90 from the signal of light receiver output.Output signal was high level signal when controller 90 determined that level (magnitude of voltage or current value) when signal is more than or equal to the second predetermined threshold, when the level of signal is low level signal during less than the second predetermined threshold.In the present embodiment, when the light of fluorescence detector 141 was blocked in surveyed area 142, the level of signal was less than the second predetermined threshold, so output signal is confirmed as low level signal.And when not being blocked through the light of surveyed area 142, because the level of signal is more than or equal to the second predetermined threshold, output signal is confirmed as high level signal.The second predetermined threshold can be identical with the first predetermined threshold.
Similarly, the analog electrical signal (voltage signal or current signal) of the light intensity that is received by light receiver is depended in the output of the light receiver of fluorescence detector 114.Be supplied to controller 90 from the signal of light receiver output.Output signal was high level signal when controller 90 determined that level (magnitude of voltage or current value) when signal is more than or equal to the 3rd predetermined threshold, when the level of signal is low level signal during less than the 3rd predetermined threshold.In the present embodiment, when the light of fluorescence detector 114 was blocked in surveyed area 115, the level of signal was less than the 3rd predetermined threshold, so output signal is confirmed as low level signal.And when not being blocked through the light of surveyed area 115, because the level of signal is more than or equal to the 3rd predetermined threshold, output signal is confirmed as high level signal.The 3rd predetermined threshold can be identical with the second predetermined threshold with the first predetermined threshold.
In the present embodiment, when print cartridge 30 was not installed to box retainer 110, controller 90 did not allow China ink to consume in printer 10.Controller 90 is configured to allow China ink to consume printer 10 based on the change of the signal of exporting from the light receiver 128 of fluorescence detector 126.
With reference to Figure 10, when the signal from fluorescence detector 141 outputs changes to high level signal (moment T0 among Fig. 8 (A) and 8 (B)) from low level signal, the processing of controller 90 beginning Figure 10.Mean that from the change of the signal of fluorescence detector 141 output print cartridge 30 begins to be inserted into the box retainer 110.At moment T0, the signal of exporting from fluorescence detector 126 is high level signal.In step S1, determine the ink supply position whether print cartridge 30 has arrived in the box retainer 110.In other words, determine whether print cartridge 30 is locked in the ink supply position by locking mechanism 144.Particularly, determine whether change to low level signal from high level signal from the signal of fluorescence detector 141 outputs.When signal changes to low level signal from high level signal, determine that print cartridge 30 has arrived ink supply section.
When definite print cartridge 30 has arrived the ink supply position (S1 is), in step S2, determine from the signal of fluorescence detector 126 outputs low level signal whether.This is determined to correspond to print cartridge 30 and whether has determining of protuberance 76.For example, with reference to figure 8 (A), when from the signal of fluorescence detector 126 output when the moment, T5 was low level signal, this is the moment that changes to low level signal from the signal of fluorescence detector 141 outputs from high level signal constantly, mean that sliding component 135 is arranged in surveyed area 127, light is blocked in surveyed area 127.Therefore, mean that print cartridge 30 has the protuberance 76 of pushing sliding component 135.On the contrary, with reference to figure 8 (B), when from the signal of fluorescence detector 126 output when the moment, T5 was high level signal, mean print cartridge 30 ' have the protuberance 76 of fracture or do not have protuberance 76 at all.
In step S2, when definite signal from fluorescence detector 126 outputs is low level signal, that is, when definite signal from fluorescence detector 126 outputs has changed to low level signal from high level signal (S2 is), controller 90 allows China ink to be consumed (S3) in printer 10.For example, be used for allowing to consume the register that black position mark is arranged on CPU91.Change from the high level signal to the low level signal means that the level of signal has been changed and crosses the first predetermined threshold, from greater than the value of the first predetermined threshold to the value less than the first predetermined threshold.
On the contrary, in step S2, when definite signal from fluorescence detector 126 outputs is high level signal, namely, when definite signal from fluorescence detector 126 outputs remained on high level signal (S2 is no), controller 90 did not allow China ink to be consumed (S4) in printer 10.For example, be used for preventing from consuming the register that black position mark is arranged on CPU91.
By this way, in the printer 10 of present embodiment, determine having or not of protuberance 76 based on the change from the signal of fluorescence detector 126 output during being inserted into print cartridge 30 in the box retainer 110.Then, when determining to have protuberance 76, allow to consume China ink.On the contrary, when definite protuberance 76 does not exist or ruptures, do not allow to consume China ink.Therefore, only when have low can be vitiable the print cartridge 30 of ink supply section 72 when being installed to box retainer 110, allow to consume China ink, when have higher can be vitiable the print cartridge 30 of ink supply section 72 when being installed to box retainer 110, do not allow to consume China ink.Therefore can reduce ink leakage in the box retainer 110, because the record of bad behavior that bad China ink supply causes or because bubble enters the fault that record head 21 causes record head 21.
In the above-described embodiments, when determining to have changed to low level signal from high level signal from the signal of fluorescence detector 141 outputs (S1 is), determine from the signal of fluorescence detector 126 outputs low level signal (S2) whether.But, after print cartridge 30 is locked in the ink supply position by locking mechanism 144, may determine also whether is low level signal (S2) from the signal of fluorescence detector 126 outputs in the moment that triggering signal is supplied from external source.Also the cover sensor that is configured to detect the opening and closing campaign of covering 19 (seeing Fig. 1) can be set at opening 112 places, and when opening 112 tegmentums 19 cover, when signal from cover sensor for seasonable, determine from the signal of fluorescence detector 126 outputs low level signal (S2) whether.
Can adopt the reflection of light detection type photo interrupter that is configured to detection of reflected to replace fluorescence detector 126.When adopting reflection detection type photo interrupter to replace fluorescence detector 126, high level and the low level of the signal of exporting from fluorescence detector 126 among Fig. 8 (A) and 8 (B) are reversed.In this case, determine from the signal of fluorescence detector 126 outputs high signal whether at step S2 middle controller 90 namely, whether change to high level signal from low level signal from the signal of fluorescence detector 126 outputs.From the low level signal to the high level signal, change the level mean signal and be changed and cross the first predetermined threshold, change to value greater than the first predetermined threshold from the value less than the first predetermined threshold.When controller 90 definite signals from fluorescence detector 126 outputs were high level signal, controller 90 allowed to consume China ink in step S3.
