Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to Japanese Patent Application No. 2012-046946 filed on Mar. 2, 2012. The entire disclosure of Japanese Patent Application No. 2012-046946 is hereby incorporated herein by reference. 
     BACKGROUND 
     1. Technical Field 
     The present invention relates to a cartridge. 
     2. Related Art 
     As printing devices which ejecta liquid such as an ink (a printing material) from a recording head toward a printing medium, ink jet printers are widely known. 
     The ink jet printers are provided with a carriage and a recording head which is mounted on the carriage. Printing is performed with regard to the printing medium by the ink being ejected from a nozzle which is formed in the printing head while the carriage moves so as to scan with regard to the printing medium. 
     Among ink jet printers, there is an ink jet printer where a cartridge which supplies ink to the recording head is mounted on the carriage (an on-carriage type). The cartridge is mounted with regard to the carriage to be able to be attached and detached. 
     Various formations (outer shapes) are proposed as cartridges which are used in an on-carriage type of printer. In the cartridges which are disclosed in Japanese Laid-Open Patent Application Publication No. 2003-34042 and Japanese Laid-Open Patent Application Publication No. 2005-22345, the height thereof is substantially the same dimension as the depth. In the cartridge which is disclosed in Japanese Laid-Open Patent Application Publication No. 2007-230249, the height thereof is substantially half of the depth. 
     SUMMARY 
     In the on-carriage type of printer, a cartridge which is taller is mounted with regard to the carriage which is provided at a position in the device which is relatively high. As a result, the height of the entire device increases. When such a printer is positioned on a living room table or the like, there is a remarkable visual sense of claustrophobia. 
     However, since the height of the cartridges in the related art is not adequately suppressed to be low, the height of printers is also increasing. On the other hand, in the cartridge, it is not possible to imprudently suppress height since it is necessary to secure a sufficient containment amount of the printing material (the ink). 
     The present invention has been carried out in consideration of the problems described above and has the object of providing a cartridge which is able to secure a sufficient containment amount for a printing material while height is suppressed to be low. 
     A cartridge adapted to be detachably mounted on a carriage in a printing device according to one aspect has a first surface as a lower surface and a second surface as an upper surface opposing each other, a third surface and a fourth surface intersecting with the first surface and the second surface and opposing each other, and a fifth surface and a sixth surface intersecting with the first surface to the fourth surface and opposing each other, where, when a distance between the first surface and the second surface is set as height and a distance between the third surface and the fourth surface is set as depth, the height is ¼ or more and ⅖ or less of the depth. 
     With the cartridge according to the aspect, the height is ⅓ of the depth. 
     With the cartridge according to the aspect, when a distance between the fifth surface and the sixth surface is set as width, the width is ⅓ or more and ½ or less of the height. 
     The cartridge according to the aspect further includes an ink supply port provided in the first surface to protrude from the first surface, one or more convex sections are provided in each of the third surface and the fourth surface, and when a distance between a tip end of the ink supply port and the second surface is set as a maximum height and a distance between a tip end of one of the one or more convex sections, which is the longest in a depth direction among the one or more convex sections which are provided in the third surface, and a tip end of one of the one or more convex sections, which is the longest in the depth direction among the one or more convex sections which are provided in the fourth surface, is set as a maximum depth, the maximum height is ¼ or more and ⅖ or less of the maximum depth. 
     The cartridge according to the aspect further includes an inclined surface provided in a corner portion where the first surface and the third surface intersect and a terminal is provided on the inclined surface. 
     The cartridge according to the aspect is adapted to be detachably mounted to the carriage which moves to reciprocate in a direction which is orthogonal to the fifth surface and the sixth surface. 
     With the cartridge according to the aspect, the first surface to the sixth surface of the cartridge are not provided with a lever for operating when attaching and detaching the cartridge with regard to the carriage.

A pressing force Ps which includes components in the +Z axial direction is imparted from the elastic member  648  with regard to the ink supply port  280  in the cartridge  20  in a state of being mounted in the holder  600 . 
     The terminal platform  700  of the printer  50  is provided more to the +X axial direction side than the ink supply pipe  640 . Device side terminals are provided in the terminal platform  700  so as to be able to be electrically connected to cartridge side terminals which are provided in the circuit substrate  400  of the cartridge  20 . A pressing force Pt which includes components in the +Z axial direction is imparted from the device side terminals which are provided in the terminal platform  700  with regard to the circuit substrate  400  in the cartridge  20  in a state of being mounted in the holder  600 . 
     The first device side fastening section  810  in the printer  50  is provided as a portion of the lever  800  and fastens to the first cartridge side fastening section  210  at a first fastening position  810 L. The first fastening position  810 L is positioned more to the +Z axial direction side and the +X axial direction side than a position where the circuit substrate  400  and the device side terminals which are provided in the terminal platform  700  come into contact. The first device side fastening section  810  limits movement of the cartridge  20  in the +Z axial direction by fastening to the first cartridge side fastening section  210 . 
     The second device side fastening section  620  in the printer  50  is provided as a portion of the holder  600  and is configured to be able to fasten to the second cartridge side fastening section  220  at a second fastening position  620 L.

The second device side fastening section  620  limits movement of the cartridge  20  in the +Z axial direction by fastening to the second cartridge side fastening section  220 . 
     Attaching and detaching of the cartridge  20  is performed while the cartridge  20  is rotated along a flat plane which is parallel to the Z axis and the X axis with the second cartridge side fastening section  220  and the second device side fastening section  620  which are engaged with each other as a rotation pivot during attaching and detaching of the cartridge  20  with regard to the holder  600 . That is, the second cartridge side fastening section  220  and the second device side fastening section  620  function as the rotation pivot of the cartridge  20  during attaching and detaching of the cartridge  20 . The details of the attaching and detaching operation of the cartridge  20  with regard to the holder  600  will be described later. 
     The lever  800  of the printer  50  has a rotation center  800   c  more to the +Z axial direction side and the +X axial direction side than the first fastening position  810 L where the first device side fastening section  810  is fastened to the first cartridge side fastening section  210 . There is a configuration so that fastening and releasing of the fastening to the first cartridge side fastening section  210  using the first device side fastening section  810  is possible due to the rotation of the lever  80  so that the first device side fastening section  810  moves from the first fastening location  810 L in the +X axial direction. 
     An operation section  830 , which is configured so that it is possible to receive an operation force Pr from the user toward the −X axial direction, is formed in the lever  800  more to the +Z axial direction side and the +X axial direction side than the rotation center  800   c . When the operation force Pr is imparted to the operation section  830  by the user, the fastening of the first cartridge side fastening section  210  using the first device side fastening section  810  is released by the lever  800  being rotated so that the first device side fastening section  810  moves from the first fastening location  810 L in the +X axial direction. Due to this, it is possible for the cartridge  20  to be removed from the holder  600 . 
     As shown in  FIG. 5 , in a state where the cartridge  20  is mounted in the holder  600 , the first fastening position  810 L is positioned more to the −Z axial direction side than the second fastening position  620 L with a distance Dz. As a result, the pressing forces Ps and Pt from the holder  600  with regard to the cartridge  20  act in a direction which strengthens the fastening of the first cartridge side fastening section  210  and the first device side fastening section  810  (a direction which includes +X axial components and +Z axial components) in a relationship of balancing the moment with the second fastening position  620 L as the rotation pivot of the cartridge  20 . Due to this, it is possible to stably maintain the cartridge  20  in the designed mounting position.

     In the embodiment, the cartridge side terminal  437  which functions as the grounding terminal is provided in a position which cuts across the flat plane Yc which passes through the center of the width (length in the Y axial direction) of the cartridge  20  and is configured so as to come in contact with the device side terminal (not shown) prior to the other cartridge side terminals  431  to  436 ,  438 , and  439  coming into contact with the device side terminals (not shown) when the cartridge  20  is mounted in the holder  600 . Due to this, since the pressing force Pt which is initially added from the holder  600  to the circuit substrate  400  is generated in the center in the width of the cartridge  20  in a direction along the Y axis, it is possible to suppress an action where the pressing force Pt which is added to the cartridge side inclined surface  408  works as a force to incline the cartridge  20  in the Y axial direction and to mount the cartridge  20  in the holder  600  in a posture which is stabilized. In addition, since the cartridge side terminal  437  which functions as the grounding terminal comes into contact with the device side terminal before the other cartridge side terminals  431  to  436 ,  438 , and  439 , it is possible to reduce defects due to a high voltage using the grounding function of the cartridge side terminal  437  even in a case where a high voltage which is not intended is applied to the cartridge  20  side. 
     In the embodiment, the cartridge side terminal  437  which functions as the grounding terminal is formed to be longer in a direction along the Z axis than the other cartridge side terminals  431  to  436 ,  438 , and  439 . Due to this, it is possible for contact between the cartridge side terminal  437  which functions as the grounding terminal and the device side terminal (not shown) which is provided in the terminal platform  700  of the holder  600  to more reliably occur before contact between the other cartridge side terminals  431  to  436 ,  438 , and  439  and the device side terminals  731  to  736 ,  738 , and  739 . In another embodiment, all of the cartridge side terminals  431  to  439  may be formed with the same size as each other. 
       FIG. 12  is a three-surface diagram illustrating outer shape dimensions of the cartridge  20 . 
     The distance between the first surface  201  and the second surface  202  is set as the height H. The height H is set as 21 mm or more and 33.6 mm or less. 
     The distance between the third surface  203  and the fourth surface  204  is set as the depth D. The depth D is set as 70 mm or more and 122 mm or less. 
     Furthermore, the height H is set as ¼ or more and ⅖ or less of the depth D. For example, the height H is ¼ of the depth D when the height H is 21 mm and the depth D is 84 mm. The height H is ⅖ of the depth D when the height H is 33.6 mm and the depth D is 84 mm. The height H is ¼ of the depth D when the height H is 28 mm and the depth D is 112 mm. The height H is ⅖ of the depth D when the height H is 28 mm and the depth D is 70 mm. 
     Since the height H of the cartridge  20  is set to be ⅖ or less of the depth D, the height H of the cartridge  20  is suppress to be low. Due to this, it is possible to suppress the height of the cartridge  20  to be low. It is possible to provide the printer  50  which is extremely compact in a visual sense. In addition, it is possible to secure a sufficient containment amount of the ink (the printing material) by the depth D being increased while suppressing the height H of the cartridge  20  to be low. 
     Since the height H of the cartridge  20  is set to be ¼ or more of the depth D, it is possible to avoid an increase in the depth dimension of the printer  50 . When the depth D is set to be large with regard to the height H of the cartridge  20 , there is a concern that, in accompaniment with this, the depth dimension of the printer  50  will increase, and as such, the printer  50  will increase in size. Accordingly, it is preferable for the depth D of the cartridge  20  to be approximately four times the height H, that is, for the height H to be ¼ or more of the depth D. 
     The optimal value of the height H is 28 mm. The optimal value of the depth D is 84 mm. In this case, the height H is ⅓ of the depth D. 
     It is possible for the balance between the height H and the depth D of the cartridge  20  to be excellent and the effects described above to be realized in an efficient manner. 
     The distance between the fifth surface  205  and the sixth surface  206  is set as the width W. The width W is set as 9.3 mm or more and 14 mm or less. 
     Furthermore, the width W is set as ⅓ or more and ½ or less of the height H. For example, the width W is ⅓ of the height H when the width W is 9.33 mm and the height H is 28 mm. The width W is ½ of the height H when the width W is 14 mm and the height H is 28 mm. 
     It is possible for the increase in size of the printer  50  to be prevented by, not only the height H of the cartridge  20  being suppressed to be low, but also the dimension of the width W being reduced. 
     The optimal value of the width W is 12.7 mm. The optimal value of the height H is 28 mm. In this case, the width W is 9/20 of the height H. 
     It is possible for the balance between the height H and the width W of the cartridge  20  to be excellent and the effects described above to be realized in an efficient manner. 
     The distance between the tip end of the ink supply port  280  and the second surface  202  is set as a maximum height J. The maximum height J is set as 22.5 mm or more and 36 mm or less. 
     The distance between the tip end of the protruding section  260  in the third surface  203  and the tip end of the second cartridge side fastening section  220  in the fourth surface  204  is set as a maximum depth E. The maximum depth E is set as 79.8 mm or more and 127.6 mm or less. 
     Furthermore, the maximum height J is set as ¼ or more and ⅖ or less of the maximum depth E. For example, the maximum height J is ¼ of the maximum depth E when the maximum height J is 22.5 mm and the maximum depth E is 90 mm. The maximum height J is ⅖ of the maximum depth E when the maximum height J is 36 mm and the maximum depth E is 90 mm. The maximum height J is ¼ of the maximum depth E when the maximum height J is 31.9 mm and the maximum depth E is 127.6 mm. The maximum height J is ⅖ of the maximum depth E when the maximum height J is 31.9 mm and the maximum depth E is 79.75 mm. 
     It is possible for the effects described above to be more sufficiently realized by paying consideration to not only the dimensions of the surfaces (the first surface  201  to the sixth surface  206 ) of the cartridge  20  but also the size of the portion (member) which is provided to protrude from the surfaces of the cartridge  20 . 
     The optimal value of the maximum height J is 31.9 mm. The optimal value of the maximum depth E is 90 mm. In this case, the maximum height J is 7/20 of the maximum depth E. 
     It is possible for the balance between the maximum height J and the maximum depth E of the cartridge  20  to be excellent and the effects described above to be realized in an efficient manner. 
     In this manner, the printer  50 , where the height is low and which is compact in a visual sense, is provided by the height H of the cartridge  20  being suppressed to be approximately ⅓ of the depth D. In particular, this is effective in terms of the printer  50  which is an on-carriage type where it is easy for the height of the printer to be increased. On the other hand, it is possible to realize the cartridge  20  where a sufficient containment amount is secured for the ink while height H of the cartridge  20  is suppressed to be low. 
     As described above, the cartridge  20  is provided with the eighth surface  208  in a corner portion where the first surface  201  and the third surface  203  intersect and the circuit substrate  400  (the cartridge side terminals) is arranged on the eighth surface  208 . 
     Since the portion where the cartridge side terminals are provided (the eighth surface  208 ) does not protrude from the surface of the cartridge  20 , it is possible to further reduce the size of the cartridge  20 . Accordingly, it is possible to contribute to further reducing the size of the printer  50 . 
     The cartridge  20  is mounted to be able to be attached and detached with regard to the carriage  520  which moves to reciprocate in a direction which is orthogonal to the fifth surface  205  and the sixth surface  206 . In this manner, it is possible to achieve a reduction in size even in the printer  50  which is an on-carriage type where the carriage  520  is provided in a position which is relatively high. 
     A lever which is operated when the cartridge  20  is attached and detached with regard to the carriage  520  is not provided in the surfaces (the first surface  201  to the sixth surface  206 ), the seventh surface  207 , and the eighth surface  208  of the cartridge  20 . The lever  800  is provided in the holder  600  of the cartridge  20 . In a case where a lever is provided in a cartridge, it is necessary to secure a certain height for the cartridge in order to secure operability of the operation lever. Contrary to this, since a lever is not provided in the cartridge  20 , it is possible to suppress the height H to be even lower since there are no limits on the height in this manner. Due to this, it is possible to effectively achieve a reduction in the size of the printer  50 . 
     Cartridge Attaching and Detaching Operation Regarding Holder 
       FIG. 13 ,  FIG. 14 , and  FIG. 15  are explanatory diagrams illustrating an attaching and detaching operation of the cartridge  20  with regard to the holder  600 . The cartridge  200  and the holder  600  with a cross section in a position which corresponds to  FIG. 5  are illustrated in  FIG. 13  to  FIG. 15 . 
     As shown in  FIG. 13 , when the cartridge  20  is mounted in the holder  600 , the cartridge  20  is moved into an inner portion of the holder  600  in the −Z axial direction from the second cartridge side fastening section  220  side and the second cartridge side fastening section  220  is inserted into the second device side fastening section  620 . In the state shown in  FIG. 13 , the first cartridge side fastening section  210  in the cartridge  20  is positioned in the +Z axial direction side of the first device side fastening section  810  which is in the lever  800  on the holder  600  side. 
     Next, from the state shown in  FIG. 13 , the cartridge  20  is rotated with the second cartridge side fastening section  220  which is inserted in the second device side fastening section  620  as the rotation pivot in a clockwise direction viewed from the +Y axial direction, that is, by the third surface  203  side being pushed toward a wall section  601  side in the holder  600 . By doing this, as shown in  FIG. 14 , the first cartridge side fastening section  210  progresses in the −Z axial direction with movement in the Y axial direction being limited by the first cartridge side fastening section  210  being guided between a pair of wall sections  860  in the lever  800  and with movement in the ZX axial direction being limited by the first cartridge side fastening section  210  coming in contact with a flat plane  822  between the pair of wall sections  860 . 
     From the state shown in  FIG. 14 , the third surface  203  side of the cartridge  20  is further rotated by being pushed. By doing this, the first cartridge side fastening section  210  is further pressed in the −Z axial direction and progresses from on the flat plane  822  of the lever  800  onto the inclined surface  824 . Then, as shown in  FIG. 15 , the inclined surface  824  of the lever  800  comes closer to being in a state which is parallel to the Z axis due to the lever  800  being rotated in a counterclockwise direction viewed from the +Y axial direction side. In the state shown in  FIG. 15 , the first cartridge side fastening section  210  progresses in the −Z axial direction onto the inclined surface  824  which is closer to being in a state which is parallel to the Z axis. At this time, in the embodiment, an abutting section  880  on a rear surface of the lever  800  abuts against an elastic member  682  and receives a pressing force, which presses to return the lever  800  in a clockwise direction viewed from the +Y axial direction, from the elastic member  682 . The pressing force is an external force which includes components in the −Z axial direction. That is, the rotation area of the lever  800  is limited by the elastic member  682 . A state, where the lever  800  is abutting against and is pressing the elastic member  682 , is maintained from the state shown in  FIG. 15  until the cartridge  20  is further pressed and the first cartridge side fastening section  210  gets past the inclined surface  824  of the lever  800 . 
     When the cartridge  20  is further rotated from the state shown in  FIG. 15  and the first cartridge side fastening section  210  has passed by the inclined surface  824  of the lever  800  and gets past a surface edge section  828 , the lever  800  is returned to its original position and the first device side fastening section  810  moves to the first fastening position  810 L and is fastened to the first cartridge side fastening section  210  as shown in  FIG. 5 . In addition, the ink supply port  280  of the cartridge  20  is connected to the ink supply pipe  640 , and the second cartridge side fastening section  220  and the second device side fastening section  620  are engaged. Due to this, the mounting of the cartridge  20  with regard to the holder  600  is completed. In addition, by the cartridge  20  being correctly mounted in the designed mounting position, the cartridge side terminals  431  to  439  and the device side terminals  731  to  739  are electrically connected and transferring of signals between the cartridge  20  and the printer  50  is performed. 
     In addition, in the embodiment, at the same time as the first cartridge side fastening section  210  passing by the inclined surface  824  of the lever  800  and getting past the surface edge section  828 , the elastic member  682  is separated from the abutting section  880  on the rear surface of the lever  800 . Due to this, it is possible to impart a clicking sensation to the user when the cartridge  20  is mounted into the holder  600 . 
     In addition, in the embodiment, the elastic member  682  does not abut against the lever  800  and an external force is not added in a state where the cartridge  20  is mounted in the holder  600 . Due to this, it is possible to prevent a change in shape of the lever  800  due to consistent pressing by the elastic member  682 . 
     In another embodiment, the elastic member  682  may abut against the lever  800  and press the lever  800  in a direction which includes components in the −X axial direction even in a state where the cartridge  20  is mounted in the holder  600 . Due to this, it is possible to more strongly impart a clicking sensation to the user when the cartridge  20  is mounted in the holder  600 . In another embodiment, the elastic member  682  may be omitted. Due to this, it is possible to reduce the number of parts. 
     Effects 
     As described above, according to the embodiment, the height H of the cartridge  20  is suppressed to be low since the height H of the cartridge  20  is set to be ⅖ or less of the depth D. Due to this, the height of the printer  50  is low and it is possible to provide the printer  50  which is extremely compact in a visual sense. This is effective in terms of the printer  50  which is an on-carriage type where it is easy for the height of the printer to be increased. 
     In particular, it is possible to even more efficiently realize the effects described above by the height H of the cartridge  20  being suppressed to approximately ⅓ of the depth D. 
     It is possible to secure a sufficient containment amount for the ink (the printing material) in the cartridge  20  by the height H of the cartridge  20  being suppressed to be low while the depth D is increased. It is possible to avoid increasing of the depth dimension of the printer  50  since the height H of the cartridge  20  is set to be ¼ or more of the depth D. 
     It is possible to even more sufficiently realize the effects described above by paying consideration to not only the dimensions of the surfaces (the first surface  201  to the sixth surface  206 ) of the cartridge  20  but also the size of the portion (member) which is provided so as to protrude from the surface of the cartridge  20 . 
     It is possible to further reduce the size of the cartridge  20  by the portion where the cartridge side terminals are provided (the eighth surface  208 ) not protruding from the surface of the cartridge  20 . 
     It is possible to further reduce the size of the cartridge  20  since the lever, which is operated when attaching and detaching the cartridge  20  with regard to the carriage  520 , is provided in the holder  600  and not the cartridge  20 . 
     Accordingly, it is possible to contribute to further reducing the size of the printer  50 . 
     Modified Examples of Outer Appearance of Cartridge 
       FIG. 16  includes diagrams (A) to (H) that are explanatory diagrams illustrating modified examples of an outer appearance of a cartridge. In  FIGS. 16(A)  to (H), eight modified examples which are different in terms of the outer appearance of the cartridge are each illustrated in  FIG. 16(A)  to  FIG. 16(H) . The same reference numerals are given with regard to configurations which are the same as the cartridge  20  in the embodiment and the description thereof is omitted. 
     The outer shell of a cartridge  20   a  in  FIG. 16(A)  has a side surface which is an elliptical shape or an oval shape. The first cartridge side fastening section  210  and the circuit substrate  400  are provided on the front surface side of the cartridge  20   a . The ink supply port  280  is formed on the bottom surface side of the cartridge  20   a . The second cartridge side fastening section  220  is formed on the rear surface side of the cartridge  20   a . The cartridge  20   a  has a constant width when the cartridge  20   a  is viewed from the front surface side. 
     A cartridge  20   b  in  FIG. 16(B)  is the same as the cartridge  20  of the embodiment excluding the point where the eighth surface  208  is connected to the −Z axial direction side of the third surface  203 . 
     A cartridge  20   c  in  FIG. 16(C)  is the same as the cartridge  20  of the embodiment excluding the point where the seventh surface  207  is omitted by extending the eighth surface  208  to the first surface  201 . 
     A cartridge  20   d  in  FIG. 16(D)  is the same as the cartridge  20  of the embodiment excluding the point where the point where there is an arrangement where a portion where the second surface  202  and the third surface  203  intersect is cut off and the point where the seventh surface  207  is omitted by the first surface  201  being inclined to the eighth surface  208 . 
     A cartridge  20   e  in  FIG. 16(E)  is the same as the cartridge  20  of the embodiment excluding the point where the circuit substrate  400  is attached to the eighth surface  208  via a spring. 
     A cartridge  20   f  in  FIG. 16(F)  is the same as the cartridge  20  of the embodiment excluding the point where a surface  208   f  which is equivalent to the eighth surface  208  is configured to be movable and the circuit substrate  400  is provided in the surface  208   f.    
     In a cartridge  20   g  in  FIG. 16(G) , the seventh surface  207  is omitted by extending the eighth surface  208  to the first surface  201 , and furthermore, a groove is formed with a shape which is cut out substantially in parallel with the eighth surface  208  from a midpoint in the third surface  203 . Then, the first cartridge side fastening section  210  is provided at a portion which is closer to the eighth surface out of two portions of the third surface  203  which are separated by the groove. Excluding these points, the cartridge  20   g  in  FIG. 16(G)  is the same as the cartridge  20  of the embodiment. 
     In a cartridge  20   h  in  FIG. 16(H) , the seventh surface  207  is omitted by extending the eighth surface  208  to the first surface  201 , and furthermore, the third surface  203  and the first cartridge side fastening section  210  are provided in an arm  212  which is fixed to be able to rotate centered on a pivot with regard to the main body of the cartridge. Excluding these points, the cartridge  20   h  in  FIG. 16(H)  is the same as the cartridge  20  of the embodiment. 
     In any of the cartridges  20   a  to  20   h  which are the respective modified examples in  FIGS. 16(A)  to (H), each of the first cartridge side fastening section  210 , the second cartridge side fastening section  220 , the ink supply port  280 , and the circuit substrate  400  are provided in positions which correspond to the cartridge  20  of the embodiment. Due to this, any of the cartridges  20   a  to  20   h  which are the respective modified examples are compatible with the cartridges  20  in the embodiment. 
     As is understood from each of the modified examples in  FIGS. 16(A)  to (H), various modified examples can be considered in regard to the shape of the outer appearance of the cartridge. Even in a case where the shape of the outer appearance of the cartridge has a shape other than a shape which is substantially rectangular, it is possible to consider six surfaces which are substantially rectangular in a virtual manner as shown by dotted lines in  FIG. 16(A)  and  FIG. 16(D) , that is, for example, the first surface  201  (the bottom surface), the second surface  202  (the upper surface), the third surface  203  (the front surface), the fourth surface  204  (the rear surface), the fifth surface  205  (the left side surface), and the sixth surface  206  (right side surface) shown in  FIG. 6  and  FIG. 7 . 
     In the specifications, the term “surface” (plane) is used with a meaning which encompasses both a plane in a virtual manner (a virtual plane, a plane which does not actually exist) and an actual surface such as described in  FIG. 6  and  FIG. 7 . In addition, in the specifications, the term “surface” is used with the meaning which encompasses both a flat plane and a curved plane. 
     Cartridge using Adaptor 
       FIG. 17  is a perspective diagram illustrating a configuration of a cartridge  20   i  which uses an adapter  299 . The cartridge  20   i  is configured to be able to be separate a containing member  200   i  and the adaptor  299 . The containing member  200   i  has the printing material containing section  200  which contains the printing material in an inner portion thereof. In a case where there is no longer any printing material in the printing material containing section  200 , it is possible to exchange the containing member  200   i  with a new containing member  200   i  or replenish the printing material in the printing material containing member  200 . When performing exchanging of the containing member  200   i  or replenishing of the printing material, it is possible to reuse the adaptor  299 . The cartridge  20   i  in  FIG. 17  is compatible with the cartridge  20  of the embodiment shown in  FIG. 6 . 
     An outer shell  22   i  of the cartridge  20   i  is configured from a combination of the outer shell of the containing member  200   i  and the outer shell of the adaptor  299 . The containing member  200   i  has the ink flow path  282  and the foam resin body  284  in addition to the printing material containing section  200 . 
     The containing member  200   i  of the cartridge  20   i  is provided with a second surface  202   i  which is equivalent to the second surface  202  of the cartridge  20   i . The containing member  200   i  is provided with a first surface  201   i , a third surface  203   i , a fourth surface  204   i , a fifth surface (not shown), a sixth section  206   i , a seventh surface  207   i , and an eighth surface  208   i  which respectively correspond to the first surface  201  and the third to the eighth surfaces  203  to  208  of the cartridge  20   i.    
     The first surface  201   i  and the second surface  202   i  oppose each other in the Z axial direction, the first surface  201   i  is positioned on the −Z axial direction side, and the second surface  202   i  is positioned on the +Z axial direction side.

The fifth surface (not shown) and the sixth surface  206   i  oppose each other in the Y axial direction, the fifth surface (not shown) is positioned on the +Y axial direction side, and the sixth surface  206   i  is positioned on the −Y axial direction side. The seventh surface  207   i  and the eighth surface  208   i  form connection surfaces which connect the first surface  201   i  and the third surface  203   i.    
     The seventh surface  207   i  is a surface which intersects at a right angle with the first surface  201   i . The seventh surface  207   i  is a surface (YZ flat plane) which is parallel to the Y axis and the Z axis. The seventh surface  207   i  as a step surface is a surface which is erected with regard to the first surface  201   i . That is, the seventh surface  207   i  is a surface which extends from the first surface  201   i  in the +Z axial direction. The seventh surface  207   i  is positioned at the −X axial direction side and the −Z axial direction side with regard to the eighth surface  208   i    
     The eighth surface  208   i  is a surface which is connected the seventh surface  207   i  and the third surface  203   i . The eighth surface  208   i  is an inclined surface which is inclined toward a direction which includes components in the +X axial direction and the −Z axial direction. The eighth surface  208   i  is a surface which is inclined with regard to the first surface  201   i  and the third surface  203   i .

     The adaptor  299   j  of the cartridge  20   j  is provided with surfaces which are equivalent to the first surface  201 , the third surface  203 , the fourth surface  204 , and the fifth surface  205  of the cartridge  20   j . The surfaces which are equivalent to the second surface  202  and the sixth surface  206  of the cartridge  20   j  out of the surfaces of the adaptor  299   j  are openings. A space which receives the containing member  200   j  is formed in an inner portion of the adaptor  299   j . The adaptor  299   j  has an opening in a portion of the first surface  201  and is connected to the ink supply pipe  640  by the ink supply port  280  of the containing member  200   j  being exposed via the opening. 
     The configuration of the cartridge  20   j  in  FIG. 18  is the same as the cartridge  20  of the embodiment which is shown in  FIG. 6  including the modified examples excluding the point where the containing member  200   j  and the adaptor  299   j  are able to be separated as described above. Here, in another embodiment or another modified example, a configuration where the containing member and the adaptor are able to be separated may be adopted as with the cartridge  20   j  of  FIG. 18 . 
     Here, the formation of the first cartridge side fastening section  210  has been simplified in the cartridge  20   j  of  FIG. 18  in comparison with the embodiment (refer to  FIG. 6 ), but the first cartridge side fastening section  210  may be the same shape as the embodiment. In addition, the dimensions and ratios of each section in the cartridge  20   j  of  FIG. 18  may be dimensions and ratios which are the same as the embodiment even though there are portions which are different to the embodiment. In addition, the protruding section  260  is omitted in the cartridge  20   j  of  FIG. 18  but the protruding section  260  may be provided in the same manner as the embodiment. 
       FIG. 19  is a perspective diagram illustrating a configuration of a cartridge  20   k  which uses an adapter. The cartridge  20   k  is provided with an adaptor  299   k , an external tank  200 T, a tube  200 L, and an auxiliary adaptor  200 S. The adaptor  299   k  of the cartridge  20   k  includes modified examples and has the same configuration as the adaptor  299   j  in  FIG. 18 . 
     The external tank T 200  of the cartridge  20   k  contains the printing material in an inner portion thereof. In the embodiment, the external tank  200 T is disposed on the outside of the printer  50  shown in  FIG. 1 . The printing material of the external tank  200 T is supplied to the auxiliary adaptor  200 S via the tube  200 L. The auxiliary adaptor  200 S of the cartridge  20   k  has an ink supply port  280   k  which is equivalent to the ink supply port  280 . 
     The external tank  200 T, the auxiliary adaptor  200 S and the tube  200 L function as a containing member  200   k  where the ink is contained. That is, it is possible to interpret the cartridge  20   k  in  FIG. 19  as having the containing member  200   k  as shown by the dotted line in the diagram. An outer shell  22   k  of the cartridge  20   k  is configured from a combination of the outer shell of the virtual containing member  200   k  and the outer shell of the adaptor  299   k.    
     In this manner, it is possible for the cartridge  20   k  in  FIG. 19  to take the configuration where the containing member  200   k  and the adaptor  299   j  are able to be separated in the same manner as the cartridge  20   i  of  FIG. 17  and the cartridge  20   j  of  FIG. 18 . In a case where there is no longer any printing material in the external tank  200 T, it is possible to exchange the external tank  200 T with a new external tank  200 T or replenish the printing material in the external tank  200 T. When performing exchanging of the external tank  200 T or replenishing of the printing material, it is possible to reuse the adaptor  299   k . The cartridge  20   k  in  FIG. 19  is compatible with the cartridge  20  of the embodiment shown in  FIG. 6 . 
     The configuration of the cartridge  20   k  in  FIG. 19  is the same as the cartridge  20  of the embodiment which is shown in  FIG. 6  including the modified examples excluding the point where the containing member  200   k  and the adaptor  299   k  are able to be separated as described above. Here, in another embodiment or another modified example, a configuration where the containing member and the adaptor are able to be separated may be adopted as in cartridge  20   k  of  FIG. 19 . 
     Modified Example Relating to Circuit Substrate  400  and Terminal Arrangement 
     In the embodiment described above, the circuit substrate  400  is provided in the cartridge  20 , but in another embodiment, the circuit substrate  400  need not be provided in the cartridge  20 . That is, the cartridge side terminals may be directly formed on the eighth surface  208 . In this case, the cartridge side inclined surface  408  becomes the surface of the eighth surface  208 . 
     In addition, a portion of wiring and the storage device  420  which are formed on the circuit substrate  400  may be provided on a surface other than the surface of the eighth surface  208 . For example, the wiring, the storage device  420 , and the cartridge side terminals  431  to  439  may be provided on a flexible printing substrate with an area which is larger than the circuit substrate  400  and a portion of the wiring and the storage section  420  may be disposed on the fifth surface  205  which is adjacent to the eighth surface  208  so that the cartridge side terminals  431  to  439  are arranged on the eighth surface  208  by folding over the flexible printing substrate. 
     In addition, the arrangement of the cartridge side terminals and the device side terminals need not be in two rows and may be one row or may be three or more rows. 
     In addition, the formation and the arrangement of the cartridge side terminals  431  to  439  are not limited to  FIG. 11A . 
       FIGS. 20A to 20C  are diagrams illustrating modified examples of the formation of the cartridge side terminals. 
     Circuit substrate  400 A,  400 B, and  400 C which are modified examples shown in  FIGS. 20A to 20C  are the same as the circuit substrate  400  in  FIG. 11A  excluding the point where the surface formation of the cartridge side terminals  431  to  439  is different. 
     In the circuit substrate  400 A of  FIG. 20A , the surface formation of the cartridge side terminals  431  to  439  is not substantially a rectangle as with the circuit substrate  400  in  FIG. 11A  and are irregular polygon shapes. 
     In the circuit substrate  400 B of  FIG. 20B , the surface formation of the cartridge side terminals  431  to  439  is not substantially a rectangle as with the circuit substrate  400  in  FIG. 11A  and are irregular formations which is surrounded by lines and curves. 
     In the circuit substrate  400 C of  FIG. 20C , the surface formation of the cartridge side terminals  431  to  439  are straight line forms with a certain width and have the same formations. The cartridge side terminals  431  to  439  are lined up in one row in the width direction. The cartridge side terminals (the mounting detection terminals)  435  and  439  are respectively disposed on both sides of the arrangement of the lines of the cartridge side terminals  431  to  439 . The cartridge side terminal (the mounting detection terminal)  431  is disposed between the cartridge side terminal (the mounting detection terminal)  435  and the cartridge side terminal (the power source terminal)  436 . The cartridge side terminal  434  (the mounting detection terminal) is disposed between the cartridge side terminal  439  (the mounting detection terminal) and the cartridge side terminal (the power source terminal)  438 . 
     In the circuit substrate  400 A,  400 B, and  400 C which are the modified examples shown in  FIGS. 20A to 20C , the disposing of the contact portion cp with the device side terminals which correspond to the cartridge side terminals  431  to  439  is the same as the embodiment of  FIG. 11A . In this manner, various modifications of the surface formation of each of the terminals are possible as long as the disposing of the contact portions cp is the same. 
     Other Modified Examples 
     It is possible to omit constituent elements which have no relation to the specific aims, actions, and effects out of the constituent elements in the embodiment described above. For example, instead of the storage device  420  of the cartridge  20 , another electric device may be mounted. 
     It is not necessary for each type of member in the embodiment described above to each be configured as independent members and a plurality of the members may be formed in an integrated manner as required. In addition, one member in the embodiment described above may be configured by combining a plurality of members. 
     The invention is not limited to an ink jet printer or an ink cartridge thereof and it is possible to also apply the present invention to an arbitrary liquid ejection device which ejects a liquid other than ink and a liquid containing container thereof. For example, it is possible to apply the present invention to the following various types of liquid ejection devices and liquid containing containers thereof. 
     Image recording devices such as a facsimile device; colorant material ejection devices which are used in manufacturing color filters which are used in image display devices such as liquid crystal displays; electrode material ejection devices which are used in forming electrodes such as in organic EL (Electro Luminescent) displays and field emission displays (FED); liquid ejection devices which eject liquids which includes a bioorganic material which is used in manufacturing biochips; sample ejection devices as precision pipettes; lubricating oil ejection devices; resin liquid ejection devices; liquid ejection devices which eject lubricating oil in a pin point manner in precision machinery such as clocks and cameras; liquid ejection devices which eject a transparent resin liquid such as an ultraviolet curing resin liquid onto a substrate in order to form a small semispherical lens (an optical lens) which is used in optical communication elements or the like; liquid ejection devices which eject an acid or alkali etching liquid in order to carry out etching of a substrate or the like; and other arbitrary liquid ejection devices which are provided with a liquid ejection head which discharges liquid droplets in small amounts. 
     Here, “liquid droplet” refers to a state of a liquid which is discharged from the liquid ejection device and includes liquid bodies with particle shapes and liquid bodies with teardrop shapes as well as liquid bodies which draw out a trail with a thread shape. In addition, it is sufficient if the “liquid” referred to here is a material which is able to be ejected from the liquid ejection device. For example, it is sufficient if the “liquid” is in a state where a substance is in a liquid phase, and materials in a liquid state such as materials with a liquid state where the viscosity is high or low and materials with a liquid state such as sols, gel water, other inorganic solvents, organic solvents, solutions, liquid resins, and liquid metals (metal fusion liquids) are included as “liquids”. In addition, not only liquids as one state of a substance but where particles of a functional material which are formed as a solid material such as a pigment or metal particles are dissolved, dispersed, or mixed in a solvent are included as “liquids”. In addition, ink as described in the embodiments described above, liquid crystals, or the like are given as representative examples of the liquid. Here, various types of liquid compositions such as typical water-based inks, oil-based inks, shell inks, and hot melt inks are included as ink.
