Fig. 5 shows the schematic diagram of the vertical view of printer shown in Figure 2 10.This schematic diagram is a structural configuration feature of thinking only to illustrate general printer 10, rather than will be accurately or represent the structural configuration of printer 10 pro rata.Printer 10 comprises an amboceptor transmitting portions 47, print zone part 42, service area part 45, ink reservoir 12 and overtravel part 49.Amboceptor transmitting portions 47 comprises paper tray 40 and is arranged on the output pallet 46 of print zone 42 fronts.Be adjacent to print zone 42, along the scan axis of representing with the x axle in the coordinate system 50 51 are service areas 45.Service area 45 is arranged on the right side of the print zone 42 of looking from the front that faces printer 10 in a most preferred embodiment.Be adjacent to print zone 42, opposed and are overtravel parts 49 with service area 45 along scan axis 51.
Overtravel part 49 is to be caused in the overtravel of the either side of print zone 42 by scanning carriage 44.This overtravel is caused in the either side edge location of printing amboceptor by printhead 16.Each printhead in a plurality of printheads 16 is all arranged along scan axis 51 in carriage 44.Therefore, for each nozzle that will link to each other with each printhead in a plurality of printheads 16 of printing place, amboceptor both sides of the edge is located, print tray 44 must overtravel to or extend to outside the printing amboceptor of print zone 42 both sides.This overtravel part 49 equates with the distance of the left side edge of the print-head nozzle distance bracket 44 of the rightmost side at the width at place, printer 10 left sides.Similarly, the overtravel of locating on the right side of printer 10 equates with the distance of the right side edge of the print-head nozzle distance bracket 44 of the leftmost side.
In the embodiment shown in fig. 5, ink reservoir 12 is positioned in the front of service area 45.In this most preferred embodiment, ink reservoir 54,56,58 and 60 all settle abreast along the line that is parallel to scan axis 51.On ink reservoir 12 and ink supply platform 14, use alignment member 62 and 66 can make ink reservoir 12 respectively near being arranged side by side separatedly.Only on the main shaft of ink reservoir 12, place alignment member 62 and make that ink reservoir 12 can be along an auxiliary axis to place near the mode that separates.Go up use alignment member 62 at this auxiliary axis (x axle) and can increase the width of ink supply platform 14 along the x axle.Therefore, alignment member 62 and this kind layout of 66 make ink reservoir 12 can be inlaid in the ink supply platform 14 that is arranged on the compactness in information desk 45 front areas.This compact ink supply platform 14 comprises that alignment member 62 and 66 is inserted in the ink supply platform 14 so that help to guide ink reservoir 12.
Each independent ink reservoir 54,56,58 and 60 all is configured to has certain width on the direction of scan axis 51 (X-axis), have certain length on the direction perpendicular to this width, has certain height on perpendicular to this length and width.Ink reservoir 54,56,58 and 60 can have as shown in Figure 2 identical width or the one or more capacity in these ink reservoirs 54,56,58 and 60 according to required ink reservoir can have either large or small width.For example, in the situation of four look printers 10 shown in Figure 2, if offer the black ink ratio of printhead 16 by ink reservoir 56 by ink reservoir 54,58 and 60 yellow that provide respectively, pinkish red, use sooner with cyan ink, then can use bigger ink reservoir (not shown) replaced oil ink container 54.This bigger ink reservoir that is used for black ink provides the convenience of using so that reduce the frequency of changing ink reservoir to the user.
Ink reservoir 54,56,58 and 60 is to arrange in the mode that separates, and generally is parallel to scan axis 51 so that allow the user can see each ink reservoir 12 and can be easily near each container 12 so that change container 12.In addition, information desk 45 is set in the right side of print zone 42, because information desk 45 has certain width along scan axis 51, this width is generally greater than along the relevant width of scan axis 51 and overtravel part 49.Carriage 44 generally has the overtravel on print zone 42 right sides, same reason, and carriage also has overtravel part 49 in the left side of print zone 42.Yet information desk 45 often has the width big than overtravel part 49 on scan axis 51, because carriage 44 generally can move to outside the print zone 42 to the printhead service fully.
The right side that ink reservoir is set in print zone 42 can be so that the most right-handed person user who accounts among the user be easy to more near ink reservoir 12.And ink reservoir is set in can have more space to set ink reservoir 12 and can not increase the total width of printer 10 on the direction that is parallel to scan axis 51 on the right front of information desk 45.
Fig. 6 a, 6b and 6c show the isometric view of the ink reservoir 12 of the best of the present invention.This ink reservoir 12 comprises an outer surface or shell 72, and this outer surface 72 has with respect to a leading edge 74 and a back edge 76 of ink reservoir 12 being inserted into the direction in the receiving station 14.
Outer surface 72 defines an opening 82 that enters in the cavity at leading edge 74 places of the ink reservoir 12 shown in Fig. 6 c.Storage device 26 with a plurality of coupled electric contacts 24 (shown in Figure 1) is installed in this cavity.Electric contact 24 is configured to and engages the corresponding electric contact 30 that links to each other with receiving station 14 can be in ink reservoir 12 suitably is inserted into printer 10 time.
Also leading edge 74 is provided with fluid issuing 20.The configuration of this fluid issuing 20 makes it can be engaged on the fluid intake 28 on the ink supply platform 14 so that the fluid that forms between ink reservoir 12 and the printer 10 is interconnected.With ink reservoir 12 along the z axle in the insertion of vertical direction and its fluid issuing 20 can be so that air rises to the top of ink reservoir 12 towards back edge 76 on leading edge 74.In use this orientation of ink reservoir 12 can prevent that the air in the ink reservoir 12 is sent to ink supply platform 14 and finally arrives printhead 16.The air of being sent into by printhead 16 can cause the print quality of difference and reduce the reliability of printhead 16.
Alignment member 62 and locking piece 64 are arranged on the ink reservoir 12.Alignment member 62 helps ink reservoir 12 is inserted into receiving station 14.Alignment member 62 is preferably disposed on leading edge 74 places that adjoin ink reservoir 12.Alignment member 62 is set guarantees ink reservoir 12 can correctly aim in early days adjoining leading edge 74 places in insertion process.In other words, if the user attempts ink reservoir 12 is inserted wrong position and/or orientation, he or she can obtain a feedback signal (before part is inserted) immediately.In addition, the user can visually aim at the leading edge spare on the ink reservoir 12 with the leading edge spare on receiving station 14.If these parts are recessed partially from the leading edge 74, difficulty will be compared in then suitable location.Can be by the location of alignment member 62 being adjoined leading edge 74 so that ink reservoir 12 early stage just aligning during insertion.In case ink reservoir 12 is inserted in the receiving station 14, locking piece 64 will mesh so that ink reservoir 12 is fixed in the receiving station 14 (seeing shown in Figure 3) with spring 68.
As previously described, electric and fluid interface is arranged on the leading edge of ink reservoir 12.Alignment member 62 is provided with the part place that can place them near needing strict aligning near leading edge 74.For the cost of the parts that make ink supply platform and ink reservoir reduces, these parts often will the situation counterdie of the tolerance of strictness not form shape have very.Therefore, will be slightly smaller than joggle piece 66 (seeing shown in Figure 4) on receiving station 14 at the joggle piece on the ink reservoir 12 66, difference in size is roughly proportional with the variation of the molding of being expected.Therefore, between corresponding intermeshing alignment member, exist some to arrange difference.These alignment member from fluid and electric interfaces stretch out many more, the effect of the electric and fluid interface on the ink container 12 and the angle difference of the layout between the corresponding interface on the receiving station 14 is also big more.Making this distance reduce to I makes the layout difference of this kind key reduce to minimum.
Be provided with grip part 86 towards back edge 76 at the place, relative two ends of ink reservoir 12.Grip part 86 is a kind of corrugated grasping surfaces, and its shape and texture make that the user is easy to pinch ink reservoir 12 with thumb and forefinger.Thereby grip part 86 provides an overhang, this overhang to be convenient to ink reservoir 12 is being pinched ink reservoir 12 extraction from ink supply platform 14 greatly at back edge 76 places.This overhang is to extend along the y axle in the longitudinal direction, makes that ink reservoir 12 can be along separate on the width of x axle shortly.
The back edge 76 that enlarges is inserted in the ink supply platform 14 except being convenient to pinch also can prevent from the ink reservoir 12 ink reservoir 12 put upside down unintentionally.Whether suitable the back edge 76 that enlarges returned the user and provided one about the visual guide function of orientation in the process of ink reservoir 12 in being inserted into printer 10.In addition, the back edge 76 of expansion can prevent printer 10 in ink reservoir 12 is inserted into ink supply platform 14, because of earlier back edge 76 being inserted the fault that causes.
Ink reservoir 12 has relevant height and the length of being represented by alphabetical H and L respectively in Fig. 6 b.Length L is on the direction that is approximately perpendicular to scan axis 51, and height H is on the direction that is approximately perpendicular to scan axis 51 and length L.Ink reservoir 12 has by the width shown in the letter w among Fig. 6 c.Width W is on the direction that is roughly parallel to scan axis 51.
The width W of ink reservoir 12 will be selected to such an extent that subtract the width W of remaining ink reservoir 12 less than the width relevant with information desk 45.For example, if all ink reservoirs 12 have identical width W, then the width of each ink reservoir 12 is less than the number of the width relevant with information desk 45 divided by ink reservoir 12.Therefore, ink reservoir 12 has the width W relevant with each container so that allow all ink reservoirs 12 can be on width to settle abreast, makes the combined width of each ink reservoir 12 less than the width relevant with information desk 45.The setting of the width of ink reservoir 12 will come fixed so that make printer 10 keep less total width along scan axis 51 according to the width of information desk 45.At Fig. 6 a, in the most preferred embodiment shown in 6b and the 6c, the width W of ink reservoir 12 is roughly 15 millimeters (mm).
