Next, be that the imaging device describes with reference to Figure 19 and 20 pairs of ink-jet recording apparatus according to second embodiment of the present utility model.According to second embodiment, hold the ink of same color as the print cartridge of black cylinder, but have different shapes, this print cartridge can be installed on the print cartridge loading part 104 as the ink-jet recording apparatus of black cylinder loading part.Figure 19 illustrates the print cartridge loading part 104 of ink-jet recording apparatus and according to the print cartridge 201y of second embodiment, 201m, the relation between 201c and the 201k (also finger writing or painting box 201 or be called print cartridge 201 when not needing to distinguish between them jointly).Figure 20 is the front view of print cartridge loading part 104.In this embodiment, represent by identical Reference numeral, and omission is to their explanation with components identical among first embodiment.
The print cartridge loading part 104 of apparatus main body 101 comprises: be respectively applied for and receive print cartridge 201y, 201m, the print cartridge patchhole 202y of 201c and 201k, 202m, 202c and 202k (also finger writing or painting box patchhole 202 or when not needing to distinguish between them, be called print cartridge patchhole 202 jointly).
With reference to accompanying drawing 20, the bottom of each patchhole 202 that is arranged on print cartridge loading part 104 as the hollow needle 91 and the needle protection as shown in figure 12 92 of the ink injection part on the apparatus main body side.
In addition, gathering sill 204y, 204m, 204c and 204k (also refer to gathering sill 204 or be called gathering sill 204 jointly when not needing to distinguish between them) are respectively formed at print cartridge patchhole 202y, 202m, on the inside upper surface of 202c and 202k, gathering sill 205y, 205m, 205c and 205k (also refer to gathering sill 205 or be called gathering sill 205 jointly when not needing to distinguish between them) are respectively formed at print cartridge patchhole 202y, and 202m is on the bottom inner surface of 202c and 202k, their position difference, and correspond respectively to and to be loaded into print cartridge patchhole 202y, 202m, the print cartridge 201y among 202c and the 202k, 201m, the ink color of 201c and 201k.
On the other hand, rib 206y, 206m, 206c and 206k (also refer to rib 206 or when not needing to distinguish between them, be called rib 206 jointly), and rib 207y, 207m, 207c and 207k (also refer to rib 207 or be called rib 207 jointly when not needing to distinguish between them) are separately positioned on print cartridge 201y, and 201m is on the precalculated position of 201c and 201k, thereby rib 206y, 206m, 206c and 206k can assemble (engagement) respectively at gathering sill 204y, 204m, among 204c and the 204k, and rib 207y, 207m, 207c and 207k can assemble (engagement) respectively at gathering sill 205y, 205m is among 205c and the 205k.The difference of the color of the ink that rib 206 is held in according to print cartridge between print cartridge 201 with respect to the position of ink supply port parts 25 and difference.The difference of the color of the ink that rib 207 is held in also according to print cartridge between print cartridge 201 with respect to the position of ink supply port parts 25 and difference.
Between a plurality of patterns (type) of each print cartridge 201, described pattern comprises the ink of same color but has different shapes, rib 206 and 207 position are defined with the position relation of the hollow needle 91 of corresponding print cartridge loading part 104, and form rib 206 and 207 under the relation of the position of this qualification.
21 describe below with reference to accompanying drawings.Here print cartridge 201 can be realized by two kinds of patterns: hold the print cartridge 201A that has relatively than the ink bag 2 of low capacity, the shape of this print cartridge 201A has less relatively thickness DA; The print cartridge 201B that holds the ink bag 2 of relatively large capacity, the shape of this print cartridge 201B have relatively large thickness DB (＞DA).In Figure 21, print cartridge 201A and 201B are represented by solid line and dotted line respectively.On first and second case members 11 and the 12 separable directions or constituting thickness DA and the DB that measures print cartridge 201A and 201B on the thickness direction of fexible film 30 of ink bag 2.
With reference to accompanying drawing 21, respectively with the rib 206 of the print cartridge 201A of the gathering sill 204 of print cartridge patchhole 202 and 205 engagements and 207 and the rib of print cartridge 202B be formed on the position identical with ink supply port parts 25.Under the situation of Figure 21, the rib 206 of print cartridge 201A and 201B is formed on from the same position of ink supply port parts 25 deviation distance D.Same, the rib 206 of print cartridge 201A and 201B is formed on from the same position of ink supply port parts 25 deviation distance D.Print cartridge 201A has identical height (along the direction of Y-axis) with 201B, and its ink supply port parts 25 also have identical height.
At this, the rib 206 of print cartridge 201 and 207 indications are contained in the color of ink wherein.In addition because rib 206 and 207 with ink supply port parts 25 between position relation limits as mentioned, rib 206 and 207 is used as positioning element, the position of qualification print cartridge 201 and be arranged on relation between the position of the hollow needle of the bottom of print cartridge patchhole 202 locating 91.
Promptly, under the situation of thin print cartridge 201A that adopts low capacity and jumbo thick print cartridge 201B, when as shown in figure 22 qualification of the relation between the position of the rib 206 of the position of print cartridge patchhole 202 and gathering sill 204 and 205 and big capacity ink box 201B and 207, the print cartridge 201A of low capacity also can be assemblied among the print cartridge patchhole 202, even print cartridge 201A have rib 206 ' and 207 ', they are limited by Figure 22 with the position relation (being represented by the ink supply port parts 25 here) of hollow needle 91.
Yet, if rib 206 ' and 207 ' form with as shown in figure 22 position relation, low capacity print cartridge 201A can be assemblied in the print cartridge patchhole 202, but stops the position alignment of ink supply port parts 25 and hollow needle 91.The result is that print cartridge 201A can not be installed in the print cartridge loading part 104.
In addition, not only have rib 206 ' and 207 ' low capacity print cartridge 201A can insert the print cartridge patchhole 202 of the print cartridge 201 that is used for another color, and the ink supply port parts 25 of print cartridge 201A also aim at the hollow needle 91 of print cartridge patchhole 202, and print cartridge 201A inserts print cartridge mistakenly and inserts in the hole.This has just caused the mixing of ink color, thereby can not obtain required image.
In addition, if rib 206 and 207 with ink supply port parts 25 between the position close tie up between the print cartridge 201 different, be that size is different with ink capacity, this is unfavorable for the user, because so just make when changing print cartridge 201, rib 206 and 207 becomes difficult and trouble with aiming at of gathering sill 204 and 205.
Therefore, the rib 206 that is used to locate and 207 with ink supply port parts 25 between relative position relation at the ink that holds same color but have between difform print cartridge 201A and the 201B and to keep identical, therefore, print cartridge 201A can be loaded in the identical print cartridge patchhole 202 of print cartridge loading part 104 with 201B.That is to say, for as the rib 206 of positioning element and 207 be used for providing ink is concerned to the position between the ink supply port parts 25 of apparatus main body side that print cartridge 201 is with the ink that holds same color but to have another black cylinder (print cartridge) difform and that can be loaded in the same imaging device be identical.
In each independent print cartridge 201, the position that limits as the rib 206 of positioning element and 207 between the ink injection part (hollow needle 91) of print cartridges 201 and print cartridge loading part 104 concerns.
Like this, according to second embodiment, by forming rib, thereby be used to hold between the print cartridge of same color ink, rib and ink supply port parts are (promptly, the ink injection part of print cartridge loading part) it is identical that the relation between keeps, even the shape difference of print cartridge, required print cartridge also can be easily mounted in the print cartridge loading part.This has just improved the operability of print cartridge, and has enlarged the range of choice of print cartridge.
That is to say, in these cases, for the print cartridge 201 that is used to hold the predetermined color ink, under the situation of not considering its ink capacity, each among low capacity type (print cartridge) 201A and large capacity version (print cartridge) 201B all can be installed in the corresponding print cartridge patchhole 202.
In this embodiment, rib 206 and 207 is formed on the print cartridge 201, and is formed in the print cartridge loading part 104 on the apparatus main body side with the gathering sills 204 and 205 of rib 206 and 207 engagements respectively.Yet rib 206 and 207 can be formed on the print cartridge loading part 104, and gathering sill 204 and 205 can be formed in the print cartridge 201, thus rib 206 and 207 respectively with gathering sill 204 and 205 engagements.
Next, with reference to accompanying drawing 23 to 25, the shell fixed structure of the aforesaid separable print cartridge of shell according to the 3rd embodiment of the present utility model is described.Figure 23 is the decomposition diagram according to the print cartridge 301 of the 3rd embodiment of the present utility model.Figure 24 is the sectional view of the part of print cartridge 301.Figure 25 is the perspective view of the print cartridge 301 in assembled state.In this embodiment, element same as the previously described embodiments is represented by identical Reference numeral, and is omitted its explanation.
With reference to accompanying drawing 23, comprise: hold the ink bag 2 of parts as ink, be used to hold the shell 303 of ink bag 2 as the print cartridge 301 of black cylinder.This shell 303 is made of first case member 311 separated from one another and second case member 312.As the above-mentioned print cartridge 1 according to first embodiment, shell 303 can be made of three separable parts (the first, the second and the 3rd case member).
In this embodiment, first and second case members 311 can separate along the thickness direction (or along the X-direction among Figure 23) that formation is contained in the fexible film 30 of the ink bag 2 in the shell 303 with 312.According to this configuration, ink bag 2 can be installed in in first and second case members 311 and 312 one (for example, in first case member 311) in advance.Therefore, can easily detect the state (for example as shown in Fig. 8 of first embodiment) that is installed in the ink bag 2 in first case member 311.
On the other hand, even under the situation of the ink bag that adopts the use fexible film to make, if ink bag and shell are integrally formed, or this shell can separate along the thickness direction perpendicular to fexible film, if ink bag is installed along the longitudinal direction, then be difficult to the ink bag of installing is done last the detection.Therefore, even the ink bag that is mounted is deformed into the shape different with required form, also be difficult to find.
Yet aforesaid separable first and second case members 311 and 312 constitute like this, make when first and second case members 311 and 312 are bonded together, and first and second case members 311 and 312 outer rim center on ink bag 2 and contact with each other.Just, the length of first and second case members 311 and 312 bonding part is relative longer, and therefore, first and second case members 311 and 312 assembly or the hardness of shell 303 may reduce.If the defective of bringing in order to eliminate reducing of hardness puts together the periphery of first and second case members 311 and 312 and all welds together, yet shell 303 just can not reuse.In addition, this also needs special tool equipment and a large amount of time, and this has just caused the reduction of output.
Therefore, the print cartridge 1 among Figure 10 of similar above-mentioned first embodiment, by using screw element 308 as element at four some places, first and second case members 311 are in the same place with 312 fastenings.The result is can guarantee that first and second case members 311 and 312 are fixed together, thereby strengthen hardness.In addition, first and second case members 311 and 312 can also be taken apart.
With reference to accompanying drawing 23 and 24, there is screw element 308 to screw in wherein turnbuckle parts 321a and is formed on four some places on first case member 311 to 321d along equidirectional.The groove 322a that has the head 308a of screw element 308 to pack into wherein is formed in second case member 312 to 322d, and their position is corresponding to 321d with the turnbuckle parts 321a of first case member 311.The through hole that is used for screw element 308 is formed on each the bottom of groove 322a to 322d.
Along with the print cartridge capacity becomes big, the shell of print cartridge also becomes big with the size that is contained in ink bag (ink holds parts) wherein.Therefore, under the situation that separated casing is screwed, need screw shell at a plurality of somes place.In this case, if the direction of screw is different between each point, still have a screw to relax, the time that perhaps screws is elongated.
Therefore, in print cartridge 301, turnbuckle parts 321a is formed on (under the situation of Figure 23) on first case member 311 to 321d, thereby screw element 308 is along screwing on the equidirectional.The result is can carry out on single direction and repeatedly screw operation.This has just increased the operability that screws, and whether also be easy to check has screw not screwed.
In addition, under the situation of using screw element 308 that the case member 311 and 312 that separates is fixed together,, then be used to hold the spatial volume increase of print cartridge 301 if the head 308a of screw element 308 is outstanding from case member 311 or 312.Particularly, in above-mentioned imaging device, print cartridge 301 is placed side by side usually.Therefore, the increase (or increase of the aperture area of the print cartridge patchhole 202 of print cartridge loading part 104) that is used to hold the spatial volume of print cartridge 301 has just caused the increase of whole imaging device size.
Therefore, for print cartridge 301, the groove 322a that the head 308a of screw 308 fits into wherein is formed in second case member 312 to 322d.This head 308a that has just prevented screw element 308 is outstanding from the surface of second case member 312.Therefore, the spatial volume (or increase of the aperture area of print cartridge patchhole 202) that does not just need to make being used in the print cartridge loading part 104 hold print cartridge 301 unnecessarily increases.Therefore, print cartridge 301 and the size that comprises the imaging device of print cartridge 301 reduce.
In addition, if the turnbuckle parts 312a that is used for trip bolt is arranged on the position of overslaugh ink bag 2 to 312d, then ink bag 2 just is in the state of improper shape.Therefore, when a large amount of inks are deposited in the ink bag 2, because the rising of interior pressure is sprayed failure or unfavorable ink drippage and may produce ink.On the other hand, when amount of ink remaining reduced, ink bag 2 can not normal deformation, and a large amount of untapped inks are deposited in the ink bag 2.
Therefore, for print cartridge 301, in order to prevent the above-described problem from occurring, the swivel nut 321a that is used for trip bolt is arranged on the position that not overslaugh is used to hold the space of ink bag 2 to 321d.
In addition, in order to reduce the image-forming apparatus in size, the intraware of print cartridge is with the integrated formation of higher degree.Therefore, print cartridge can have one and only be positioned at the handle component that limits the position, and these parts are used for print cartridge being installed to apparatus main body or print cartridge being taken out from apparatus main body.Especially, in according to the print cartridge that can separate of the present utility model along the fexible film thickness direction, handle component can be arranged on print cartridge assembled portion near, in this assembled portion, the detachable component of print cartridge shell is assembled with each other.In this case, when assembling or dismounting print cartridge, apply a power artificially.Therefore, consider the power bigger that applies than desired value.Therefore, near generation misalignment assembled portion owing to be out of shape, this is unfavorable for operation.
Therefore, in print cartridge 301, turnbuckle parts 321b is arranged on handle component 310 inside of (being equal to the projecting part 42 among Fig. 2), thereby near handle component 301, first and second case members 311 and 312 tighten together, and have increased the intensity of print cartridge 301.
As mentioned above, compare, use the fastening structure of screw not need special instrument, guaranteed firm fixing, and had extraordinary re-usability (recuperability) with the fastening method of for example welding.On the other hand, this fastening method can be expected by anyone, therefore print cartridge easily can be taken apart.Especially, because the user may by mistake damage ink bag to the dismounting that print cartridge carries out out of curiosity.If this causes the leakage of ink, then pollute its environment most probably.In addition, also have the another one problem, i.e. the design of print cartridge may be cancelled from the outside as seen and in a large number owing to screw.
