Between the first tongue-piece portion 70 and the container side insertion hole 61 in the longitudinal direction of the upper end portion of the inner side surface of the right side wall forming member 51, a pair of through-holes 77 serving as an example of a supplement portion is formed so as to interpose the first to fourth ribs 66 to 69 therebetween in the vertical direction. Between the first tongue-piece portion 70 and the second tongue-piece portion 71 in the longitudinal direction of the upper end portion of the inner side surface of the right side wall forming member 51, a pair of through-holes 77 is formed so as to interpose the second to fourth ribs 67 to 69 therebetween in the vertical direction.
Between the second tongue-piece portion 71 and the third tongue-piece portion 72 in the longitudinal direction of the upper end portion of the inner side surface of the right side wall forming member 51, a pair of through-holes 77 is formed so as to interpose the third rib 68 and the fourth rib 69 therebetween in the vertical direction. A wire 78 is caused to pass through the respective pair of through-holes 77 so as to form an annular shape, and end portions of the wire 78 are connected to each other. In this manner, the respective connection tubes 37 are reliably held.
Next, a configuration of the ink container will be described in detail. As illustrated in
The ink bag 90 is formed by welding peripheral edges of two flexible films 90a in a state where a cylindrical ink outlet portion (not illustrated) is interposed between the outer peripheral edges of the two rectangular-shaped flexible films 90a. That is, the ink bag 90 is a bag body configured to have the flexible films 90a serving as two opposing flexible walls, and is formed so that the two opposing flexible films 90a are caused to come close to each other by consumption of the ink contained inside thereof. In the embodiment, a flexible portion is configured to have the two flexible films 90a configuring the ink bag 90.
In this manner, the ink bag 90 contracts in response to the consumption of the ink. Therefore, it is possible to prevent the ink from not being supplied to the recording head 28 side, which is caused by a negative pressure inside the ink bag 90 in response to the consumption of the ink.
The support member 92 of the respective ink containers 17 includes a first support member 105 and a second support member 106 which are attached to an upper end portion of the ink bag 90 so as to mutually interpose the upper end portion therebetween. Cylindrical-shaped convex portions 123 inserted into an ink bag through-hole (not illustrated) formed in the ink bag 90 are respectively protruded in both end portions in the second support member 106. An engagement cut-out recess 130 engaging with the convex portion 123 inserted into the ink bag through-hole is formed in the second support member 106.
Next, an operation when the respective ink containers 17 internally filled with the ink are set in the case 18 will be described. As illustrated in
Then, both end portions of the first support member 105 are respectively inserted into the cut-out recess 56a (refer to
In the respective ink containers 17, the lower end of the ink bag 90 is lowered (illustrated by the two-dot chain line in
Then, as illustrated in
Then, if the inks of the respective ink containers 17 are consumed by the printing of the sheet P, the ink bag 90 of the respective ink containers 17 is gradually deflated in response to the consumption of the inks. At this time, since the left side wall forming member 52 configuring the container body 20 of the case 18 is transparent, a deflated condition (displacement state) of the ink bag 90 of the respective ink containers 17 inside the case 18 is visibly checked from outside of the case 18 through the left side wall forming member 52 without opening the lid body 21.
In this case, in particular, the left side wall forming member 52 occupies not only the majority of the left side surface of the container body 20, but also the majority of the left half on the front side surface and the rear side surface of the container body 20. The respective ink containers 17 are arranged side by side in the longitudinal direction so as to be parallel to each other in a state of being tilted so that the left side ink container is positioned at the further front side than the right side ink container inside the case 18.
Therefore, the deflated condition of the ink bag 90 of all the ink containers 17 inside the case 18 is visibly checked from the front side of the case 18 (from outside of the case 18). Accordingly, it is possible to estimate the replacement time for the respective ink containers based on the deflated condition of the ink bag 90 in the respective ink containers 17.
The above-described printer 11 includes the recording head 28 which can eject the ink onto the sheet P, the transport unit which transports the sheet P to the recording head 28, the housing 25 which contains the recording head 28 and the transport unit, the case 18 which is arranged on the outer side surface of the housing 25 so that the bottom wall forming member 50 is positioned higher than the bottom surface of the housing 25, and which serves as the holder for holding the ink container 17 containing the ink, and the supply unit (connection tube 37) which supplies the ink from the ink container 17 to the recording head 28.
According to this configuration, there is provided the case 18 which is arranged on the outer side surface of the housing 25 so that the bottom wall forming member 50 is positioned higher than the bottom surface of the housing 25, and which holds the ink container 17 containing the ink. In this manner, it is possible to install even the printer 11 using the ink container 17 having the large containing capacity without increasing the installation space for the printer 11.
In the present embodiment, the ink supply device 15 having the case 18 is provided on the left side surface (one outer side adjacent to the outer side surface having the opening 30 which is the insertion port of the housing 25) of the main apparatus body 14. However, the ink supply device may be provided which has the case holding the ink container 17 on the right side surface (the other outer side adjacent to the outer side surface having the opening 30) of the main apparatus body 14.
At least one ink container 17 out of the multiple ink containers 17 may have the containing capacity different from that of the other ink container 17. According to this configuration, depending on types of the liquid, it is possible to change the containing capacity of the liquid which can be supplied to the recording head.
For example, the multiple ink containers 17 include the ink container 17 containing at least the black ink, and the ink container 17 containing the black ink has the containing capacity larger than that of the other ink container 17. According to this configuration, it is possible to supply the recording head 28 with the more of the black ink frequently used.
The bottom wall forming member 50 of the case 18 may be arranged at a position higher than the bottom surface of the housing 25 by 50 mm. In this manner, in a state where the recording media such as the sheets are stacked one on another up to less than 50 mm, the recording media can be partially placed on the lower portion of the case 18 by being stacked thereon. Therefore, the installation area for the printer 11 including the recording media placed on the left side of the main apparatus body 14 can be reduced.
In the ink container 17, both end portions of the support member 92 are not necessarily supported and suspended by the right recess 56 and the left recess 59 of the case 18. That is, the ink container 17 may be contained in a state of being placed on the inner bottom surface of the case 18. In this case, the inner bottom surface (bottom wall 49) of the case 18 functions as a support portion for supporting the ink container 17.
A hard support portion having a shape which can be supported by the right recess 56 and the left recess 59 of the case 18 may be disposed in the upper end portion (one end side which is the cap 87 side) of the ink bag 90 of the ink container 17, as a liquid container support portion instead of the support member 92. According to this configuration, the ink container 17 can be handled by gripping the support portion. Therefore, it is possible to easily attach and detach the ink container 17 to and from the right recess 56 and the left recess 59 of the case 18.
The ink container 17 is not necessarily supported by the right recess 56 and the left recess 59 of the case 18 via the support member 92. The distance between the right side wall 45 and the left side wall 46 in the case 18 is not necessarily shorter than the width of the ink container 17.
The case 18 holds the multiple ink containers 17 so as not to be overlapped with each other in the height direction of the housing 25. In this manner, the ink containers 17 do not get affected by each other, and the ink can be fully used up.
The case 18 does not necessarily have the transparent left side wall forming member 52 through which the deflated condition of the ink bag 90 in response to the consumption of the ink inside the ink container 17 is visibly checked. The opening 19 of the case 18 is not necessarily disposed in the upper end of the container body 20, and may be disposed on a side surface of the container body 20.
The lid body 21 of the case 18 may be omitted. The ink bag 90 is not necessarily configured to entirely have the flexible film 90a. That is, the ink bag 90 may be configured to have a flexible portion, a portion of which is formed of a flexible material. The material configuring the flexible portion of the ink bag 90 may be transparent or opaque.
The side wall of the container body 20 of the case 18 is not necessarily configured by assembling the right side wall forming member 51 and the left side wall forming member 52 which are laterally divided. That is, the side wall of the container body 20 may be configured by assembling three or more divided members, or may be configured to have one undivided member.
The through-hole 77 formed in the container body 20 of the case 18 may be omitted. The cut-out portion 57 disposed in the edge member 53 of the case 18 may be omitted. Instead of the cut-out portion 57, a hole into which the connection tube 37 can be inserted may be disposed in the edge member 53 of the case 18 as an insertion portion. The right side wall forming member 51 and the left side wall forming member 52 which configure the container body 20 may have a plate shape which is bent in an L-shape.
The color of the respective caps 87 may be matched with the color of the ink contained in the respective ink containers 17 corresponding to the respective caps 87. According to this configuration, it is possible to prevent the cap 87 from being erroneously connected to the ink container 17.
In the printer 11, the case 18 is not necessarily detachably attached to the printing unit 12 of the main apparatus body 14. That is, the case 18 may be fixedly attached to the printing unit 12 of the main apparatus body 14.
In the printer 11, the height of the case 18 is not necessarily set to be lower than the height of the reading surface 13a. That is, the height of the case 18 may be set to be the same as the height of the reading surface 13a, or may be set to be higher than the height of the reading surface 13a.
Next, an operation when the document G larger than the reading surface 13a is read by the reading unit 13 of the printer 11 will be described.
As illustrated in
At this time, the height of the case 18 is aligned with the height of the reading surface 13a. That is, the height of the case 18 is lower than the height of the reading surface 13a by 5 mm.
Therefore, the document G is supported on the case 18 without being partially caught on the side surface of the case 18. Then, if the reading unit 13 is operated in a state where the automatic document feeder 16 is closed, the region on the reading surface 13a in the document G is read.
In this manner, the portion of the document G which protrudes from the reading surface 13a is partially supported by the case 18. Accordingly, the position of the document G is stabilized, thereby enabling the reading unit 13 to accurately read the document G.
