- the protrusions 137, 138 contact the support plate 126 of the cartridge mounting portion 110 from above when the mounting of the ink cartridge 30 to the cartridge mounting portion 110 is completed. More specifically, the protrusion 137 contacts the protrusion 127 of the support plate 126, and the protrusion 138 contacts the protrusion 128 of the support plate 126.
- the protrusions 137, 138 are optional. When the protrusions 137, 138 are not provided, the protrusions 127, 128 contact the lower surface of the first protrusion 85 from below. The protrusions 127, 128 are also optional. When the protrusions 127, 128 are not provided, the protrusions 137, 138 contact the upper surface of the support plate 126. When both the protrusions 137, 138 and the protrusions 127, 128 are not provided, the lower surface of the first protrusion 85 contacts the upper surface of the support plate 126.
- valve 77 closes the ink supply opening 71. The flow of ink from the ink chamber 36 to the outside of the ink cartridge 30 is blocked.
- the ink cartridge 30 is inserted into the case 101 via the opening 112 of the cartridge mounting portion 110.

- the rod 125 is further inserted into the recess 96.
- the protrusion 137 contacts the protrusion 127 and the protrusion 138 contacts the protrusion 128. With this contact, the movement of the first protrusion 85 in the downward direction 53 is restricted.
- the first wall 161 and the second wall 162 of the main body 163 of the contact unit 160 enter the first space 181 and the second space 182, respectively. While the first guide surface 131 and the third guide surface 133 are guided by the first wall 161 and the second guide surface 132 and the fourth guide surface 134 are guided by the second wall 162, the IC board 64 reaches a position directly below the contacts 106. Until the IC board 64 reaches the position below the contacts 106, the lower ends of the contacts 106 are positioned further in the downward direction 53 than the upper surface of the electrodes 65. When the IC board 64 reaches the position below the contacts 106, IC board 65 pushes up the contacts 106 in the upward direction 54, and the contacts 106 are elastically deformed in the upward direction 54. As such, the electrodes 65 contact the corresponding contacts 106. When this occurs, electrical connection between the IC (not shown) of the IC board 64 and the controller 1 is established, and the controller 1 becomes able to access the IC.
- the IC board 64 When the electrodes 65 contact the contacts 106, the IC board 64 is urged in the downward direction 53 by the elastically deformed contacts 106. Nevertheless, because the protrusions 137, 138 of the first protrusion 85 contact the protrusions 127, 128 of support plate 126, respectively, the movement of the first protrusion 85 in the downward direction 53 is restricted. Therefore, the IC board 64 is accurately positioned relative to the contacts 106 in the downward direction 53 and the upward direction 54.
- the protrusion 43 of the rear cover 31 reaches the lock portion 145, and the inclined surface 155 slides on the lock portion 145.
- the sliding contact between the inclined surface 155 and the lock portion 145 causes the ink cartridge 30 to pivot clockwise in Fig. 8 about a pivot center which is the center of the ink supply opening 71 through which the ink supply tube 102 is inserted.
- the attitude of the ink cartridge 30 in Fig. 8 is an example of a second attitude.
- the lock surface 151 of the protrusion 43 is positioned below the lock portion 145, i.e., positioned further in the downward direction 53 than the lock portion 145.
- the inclined surface 155 is positioned further in the insertion direction 51 than the lock portion 145.
- the ink cartridge 30 pivots counterclockwise in Fig. 9 about the pivot center which is the center of the ink supply opening 71 through which the ink supply tube 102 is inserted.
- the lock surface 151 When the ink cartridge 30 pivots counterclockwise, the lock surface 151 reaches a position in which the lock surface 151 and the lock portion 145 face each other in the insertion direction 51 and the removal direction 52. Moreover, when the ink cartridge 30 pivots counterclockwise, the rear cover 31 contacts the lock portion 145. When this occurs, the impact of the contact tells the user that the insertion of the ink cartridge 30 is completed. When the user stops pushing the ink cartridge 30, the ink cartridge 30 is moved in the removal direction 52 by the urging force of the pulling spring 114 applied via the slider 107 and the urging force of the coil spring 78.
- the attitude of the ink cartridge 30 in Fig. 9 is an example of the first attitude.
- the mounting of the ink cartridge 30 to the cartridge mounting portion 110 is thus completed.
- the ink cartridge 30 is locked or retained in the cartridge mounting portion 110 with the lock surface 151 contacting the lock portion 145 in the removal direction 52 against the urging force of the pulling spring 114 and the urging force of the coil spring 78 in the removal direction 52.
- the protrusion 127 is positioned further in the right direction 55 than the IC board 64.
- the protrusion 128 is positioned further in the left direction 56 than the IC board 64.
- the protrusion 127 is positioned between the board supporting portion 130 and the third wall 173.
- the protrusion 127 is positioned between both ends of the third wall 173 in the insertion direction 51 and the removal direction 52. Therefore, the protrusion 127 overlaps the first space 181 when viewed in the upward direction 54 or the downward direction 53. In this embodiment, the protrusion 127 entirely overlaps the first space 181. In another embodiment, the protrusion 127 partly overlaps the first space 181.
- the protrusion 128 is positioned between the board supporting portion 130 and the fourth wall 174.
- the protrusion 128 is positioned between both ends of the fourth wall 174 in the insertion direction 51 and the removal direction 52. Therefore, the protrusion 128 overlaps the second space 182 when viewed in the upward direction 54 or the downward direction 53. In this embodiment, the protrusion 128 entirely overlaps the second space 182. In another embodiment, the protrusion 128 partly overlaps the second space 182.
- the operation surface 92 When a user wishes to remove the ink cartridge 30 from the cartridge mounting portion 110, the user pushes down the operation surface 92.
- the operation surface 92 When the ink cartridge 30 is in the first attitude, the operation surface 92 is viewable when the ink cartridge 30 is viewed in the downward direction 53 and is viewable when the ink cartridge 30 is viewed in the insertion direction 51.
- the operation surface 92 faces the upward direction 54 and the removal direction 52. Therefore, when the user pushes the operation surface 92 when the ink cartridge 30 is in the first attitude to release the ink cartridge 30, the user's force is directed toward the downward direction 53 and the insertion direction 51.
- the lock surface 151 separates from the lock portion 145. Due to the force directed toward the downward direction 53, the ink cartridge 30 pivots from the first attitude to the second attitude. Therefore, compared to a situation in which the ink cartridge 30 pivots from the first attitude to the second attitude while the lock surface 151 slides on the lock portion 145, the force needed to be applied to the operation surface 92 to cause the ink cartridge 30 to pivot from the first attitude to the second attitude becomes smaller, and the user can readily release the ink cartridge 30.
- the lock surface 151 is positioned below the lock portion 145, i.e., positioned further in the downward direction 53 than the lock portion 145.
- the urging force of the pulling spring 114 and the coil spring 78 moves the ink cartridge 30 in the removal direction 52.
- the urging force is no longer applied to the ink cartridge 30, and the ink cartridge 30 stops moving in the removal direction 52.
- the user can take the ink cartridge 30 out of the cartridge mounting portion 110.
- the ink cartridge 30 is inserted into the cartridge mounting portion 110 and mounted to the cartridge mounting portion 110 while the first guide surface 131 is guided by the first wall 161 and the second guide surface 132 is guided by the second wall 162.

- the IC board 64 if the IC board 64 is positioned offset from the board supporting portion 130 in the left direction 56, the IC board 64 contacts the second wall 162 during the insertion of the ink cartridge 30 into the cartridge mounting portion 110. Therefore, if the IC board 64 is offset from the board supporting portion 130 in the right direction 55 or the left direction 56, the ink cartridge 30 cannot be mounted to the cartridge mounting portion 110.
- the electrodes 65 of the IC board 64 which is supported on the board supporting portion 130 at an accurate position can contact the contacts 106 of the cartridge mounting portion 110 while the electrodes 65 of the IC board 64 which is offset from the board supporting portion 130 in the right direction 55 or the left direction 56 cannot contact the contacts 106 of the cartridge mounting portion 110.
- the electrodes 65 of the ink cartridge 30 and the contacts 106 of the cartridge mounting portion 110 can securely contact each other.
- the IC board 64 may overlap the first wall 161 and the second wall 162 when viewed in the right direction 55 or the left direction 56, or may be positioned further in the insertion direction 51 than the first wall 161 and the second wall 162.
- the IC board 64 is not damaged by the first wall 161 and the second wall 162 when the first wall 161 is guided by the first guide surface 131 and the second wall 162 is guided by the second guide surface 132.
- the electrodes 65 of the ink cartridge 30 contact the contacts 106 of the cartridge mounting portion 110 properly.
- the third wall 173 and the fourth wall 174 extend beyond the electrodes 65 in the upward direction 54, when the ink cartridge 30 contacts something, the IC board 64 is protected by the third wall 173 and the fourth wall 174. A likelihood that the IC board 64 is damaged can be reduced.
- the first guide surface 131 and the third guide surface 133 are staggered along the insertion direction 51 and the removal direction 52

- at least a portion of the third wall 173 does not overlap the contact portion of the IC board 64
- at least a portion of the fourth wall 174 does not overlap the contact portion of the IC board 64. Therefore, if the IC board 64 contacts the board supporting portion 130 via ultraviolet curable adhesive, the optical path of the ultraviolet light directed toward the ultraviolet curable adhesive applied on the contact portion of the IC board 64 in the right direction 55 or the left direction 56 is not blocked when the ink cartridge 30 is manufactured. Therefore, the manufacture of the ink cartridge 30 becomes easy.
- the electrodes 65 still remains in contact with the contacts 106 of the cartridge mounting portion 110.
- the protrusion 137 contacts the protrusion 127 and the protrusion 138 contacts the protrusion 128 when the mounting of the ink cartridge 30 to the cartridge mounting portion 110 is completed, a likelihood is reduced that the ink cartridge 30 rotated around an axis extending in the insertion direction 51. Therefore, the electrodes 65 contact the contacts 106 of the cartridge mounting portion 110 further securely.
- the controller 1 accesses the IC of the IC board 64 via the electrodes 65 and the contacts 106, the controller 1 can read data out of the IC, or write date in the IC, or both.
- the third guide surface 133 and the fourth guide surface 134 are provided to the ink cartridge 30. Nevertheless, the third guide surface 133 and the fourth guide surface 134 are optional. Even if the third guide surface 133 and the fourth guide surface 134 are not provided, the ink cartridge 30 is inserted into the cartridge mounting portion 110 and mounted to the cartridge mounting portion 110 while the first guide surface 131 is guided by the first wall 161 and the second guide surface 132 is guided by the second wall 162.

Abstract
Description
- The present invention relates to a system in which a consumable cartridge is mountable to a mounting portion.
- A known ink-jet printer, as described in
U.S. Patent Number 7,703,902 , has an ink cartridge and a holder to which the ink cartridge is mountable. The ink cartridge has an electrical connection terminal portion, and the holder has a connector configured to contact the electrical connection terminal portion. By correctly determining a relative position between the ink cartridge and the holder, an electrical connection between the electrical connection terminal portion and the connector is secured. - Nevertheless, provided that the electrical connection terminal portion is supported on the ink cartridge at a wrong position, even if the relative position between the ink cartridge and the holder is correctly determined, the electrical connection between the electrical connection terminal portion and the connector may not be secured. In particular, the electrical connection terminal portion may contact the connector right after the ink cartridge is mounted to the holder, but may separate from the connector by shock and vibration when the ink-jet printer is used.
- Therefore, a need has arisen for a system which overcomes these and other shortcomings of the related art. A technical advantage of the present invention is that an electrical interface of a consumable cartridge and a contact of a mounting portion may securely contact each other.
- According to an aspect of the present invention, a system comprises: a mounting portion; a consumable cartridge configured to store a consumable, wherein the consumable cartridge is configured to be inserted into the mounting portion in a first direction and thereby to be mounted to the mounting portion, and configured to be removed from the mounting portion in a second direction opposite the first direction; and a consuming portion configured to consume the consumable to be supplied from the consumable cartridge when mounting of the consumable cartridge to the mounting portion is completed. The consumable cartridge comprises: a consumable chamber configured to store a consumable; a board; a board supporting portion configured to support the board; an electrical interface positioned on the board and facing a third direction which is perpendicular to the first direction and the second direction; a first guide surface positioned further in a fourth direction opposite the third direction than the board, wherein the first guide surface faces a fifth direction which is perpendicular to the first, second, third, and fourth directions; and a second guide surface positioned further in the fourth direction than the board, wherein the second guide surface faces a sixth direction opposite the fifth direction. The mounting portion comprises: a contact configured to contact the electrical interface when the mounting of the consumable cartridge to the mounting portion is completed; a first wall positioned further in the fifth direction than the contact and comprising a portion positioned to overlap a moving path of the board when viewed in the fifth direction, wherein the board moves in the moving path when the consumable cartridge is inserted into the mounting portion; and a second wall positioned further in the sixth direction than the contact and comprising a portion positioned to overlap the moving path of the board when viewed in the sixth direction, wherein when the consumable cartridge is inserted into the mounting portion; a first space is formed, wherein an end of the first space in the sixth direction is defined by the first guide surface, and the first space is opened in the first direction and the third direction, wherein the first space receives the first wall; and a second space is formed, wherein and end of the second space in the fifth direction is defined by the second guide surface, and the second space is opened in the first direction and the third direction, wherein the second space receives the second wall.
- With this configuration, the consumable cartridge is inserted into the mounting portion and mounted to the mounting portion while the first guide surface is guided by the first wall and the second guide surface is guided by the second wall. As a result, the electrical interface on the board of the consumable cartridge contacts the contact of the mounting portion properly.
- If the board is positioned offset from the board supporting portion in the fifth direction, the board contacts the first wall during the insertion of the consumable cartridge into the mounting portion. Similarly, if the board is positioned offset from the board supporting portion in the sixth direction, the board contacts the second wall during the insertion of the consumable cartridge into the mounting portion. Therefore, if the board is offset from the board supporting portion in the fifth direction or the sixth direction, the consumable cartridge cannot be mounted to the mounting portion.
- An electrical interface of the board which is supported on the board supporting portion at an accurate position can contact the contact of the mounting portion while an electrical interface of the board which is offset from the board supporting portion in the fifth direction or the sixth direction cannot contact the contact of the mounting portion. As a result, the electrical interface of the consumable cartridge and the contact of the mounting portion can securely contact each other.
- Incidentally, when the mounting of the consumable cartridge to the mounting portion is completed, the board may overlap the first wall and the second wall when viewed in the fifth direction or the sixth direction, or may be positioned further in the first direction than the first wall and the second wall.
- Optionally, the first guide surface is positioned further in the fifth direction than the board, or positioned at the same position as an end of the board in the fifth direction, wherein the second guide surface is positioned further in the sixth direction than the board, or positioned at the same position as an end of the board in the sixth direction.
- With this configuration, the first wall is guided by the first guide surface and the second wall is guided by the second guide surface while the board is not damaged by the first wall and the second wall.
- Optionally, the consumable cartridge comprises: a third wall comprising a third guide surface positioned further in the fifth direction than the first guide surface and facing the sixth direction, wherein the third guide surface defines an end of the first space in the fifth direction when the consumable cartridge is inserted into the mounting portion; and a fourth wall comprising a fourth guide surface positioned further in the sixth direction than the second guide surface and facing the fifth direction, wherein the fourth guide surface defines an end of the second space in the sixth direction when the consumable cartridge is inserted into the mounting portion.
- With this configuration, the consumable cartridge is inserted into the mounting portion and mounted to the mounting portion while the first guide surface and the third guide surface are guided by the first wall and the second guide surface and the fourth guide surface are guided by the second wall. As a result, the electrical interface on the board of the consumable cartridge contacts the contact of the mounting portion properly.
- Optionally, the third wall and the fourth wall extend beyond the electrical interface in the third direction.
- With this configuration, when the liquid cartridge contacts something, the board is protected by the third wall and the fourth wall. A likelihood that the board is damaged can be reduced.
- Optionally, the first guide surface and the third guide surface are staggered along the first direction and the second direction, and the second guide surface and the fourth guide surface are staggered along the first direction and the second direction. Optionally, when viewed in the fifth direction or the sixth direction, at least a portion of the third wall does not overlap a portion of the board, which portion contacts the board supporting portion, and at least a portion of the fourth wall does not overlap the portion of the board.
- With this configuration, if the board contacts the board supporting portion via ultraviolet curable adhesive, the optical path of the ultraviolet light directed toward the ultraviolet curable adhesive applied between the board and the board supporting portion in the fifth direction or the sixth direction is not blocked when the consumable cartridge is manufactured. Therefore, the manufacture of the consumable cartridge becomes easy.
- Optionally, a dimension of the electrical interface along the fifth direction and the sixth direction is greater than a sum of a gap along the fifth direction and the sixth direction between the first guide surface and the first wall received in the first space and a gap along the fifth direction and the sixth direction between the third guide surface and the first wall received in the first space, wherein the dimension of the electrical interface is also greater than a sum of a gap along the fifth direction and the sixth direction between the second guide surface and the second wall received in the second space and a gap along the fifth direction and the sixth direction between the fourth guide surface and the second wall received in the second space.
- With this configuration, when the first wall moves in the first space and the second wall moves in the second space in the fifth direction and the sixth direction, the electrical interface still remains in contact with the contact of the mounting portion.
- Optionally, the consumable cartridge comprises a first protrusion and a second protrusion positioned away from each other in the fifth direction and the sixth direction, wherein the first protrusion and the second protrusion protrude in the fourth direction, and contact the mounting portion when the mounting of the consumable cartridge to the mounting portion is completed. Alternatively or at the same time, the mounting portion comprises a third protrusion and a fourth protrusion positioned away from each other in the fifth direction and the sixth direction, wherein the third protrusion and the fourth protrusion protrude in the third direction, and contact the consumable cartridge when the mounting of the consumable cartridge to the mounting portion is completed. Optionally, when the consumable cartridge comprises the first protrusion and the second protrusion, and the mounting portion comprises the third protrusion and the fourth protrusion, the first protrusion contacts the third protrusion and the second protrusion contacts the fourth protrusion when the mounting of the consumable cartridge to the mounting portion is completed.
- With this configuration, a likelihood is reduced that the consumable cartridge rotates around an axis extending in the first direction when the mounting of the consumable cartridge to the mounting portion is completed. Therefore, the electrical interface contacts the contact of the mounting portion further securely.
- Optionally, the first protrusion or the third protrusion is positioned further in the fifth direction than the board, and the second protrusion or the fourth protrusion is positioned further in the sixth direction than the board when the mounting of the consumable cartridge to the mounting portion is completed.
- With this configuration, the distance between the first protrusion and the second protrusion or between the third protrusion and the fourth protrusion becomes larger, and therefore the rotation of the consumable cartridge is further suppressed.
- Optionally, when viewed in the third direction or the fourth direction, the first protrusion or the third protrusion at least partly overlaps the first space, and the second protrusion or the fourth protrusion at least partly overlaps the second space when the mounting of the consumable cartridge to the mounting portion is completed.
- Optionally, the system further comprises a controller, wherein the consumable cartridge comprises an integrated circuit electrically connected to the electrical interface, and the controller is configured to access the integrated circuit via the electrical interface.
- When the controller accesses the integrated circuit, the controller can read date out of the integrated circuit, or write data in the integrated circuit, or both.
- Optionally, the third direction is an upward direction and the fourth direction is a downward direction.
- According to another aspect of the invention, a consumable cartridge is configured to be inserted into a mounting portion in a first direction and thereby to be mounted to the mounting portion, and configured to be removed from the mounting portion in a second direction opposite the first direction. The consumable cartridge comprises: a consumable chamber configured to store a consumable; a board; a board supporting portion configured to support the board; an electrical interface positioned on the board and facing a third direction which is perpendicular to the first direction and the second direction; a first guide surface positioned further in a fourth direction opposite the third direction than the board, wherein the first guide surface faces a fifth direction which is perpendicular to the first, second, third, and fourth directions; a second guide surface positioned further in the fourth direction than the board, wherein the second guide surface faces a sixth direction opposite the fifth direction; a third guide surface positioned further in the fifth direction than the first guide surface and facing the sixth direction; and a fourth guide surface positioned further in the sixth direction than the second guide surface and facing the fifth direction, wherein the first guide surface and the third guide surface define ends of a first space in the sixth direction and the fifth direction, respectively, and the first space is opened in the first direction and the third direction, and wherein the second guide surface and the fourth guide surface define ends of a second space in the fifth direction and the sixth direction, respectively, and the second space is opened in the first direction and the third direction.
- With this configuration, the consumable cartridge is inserted into the mounting portion and mounted to the mounting portion while the first guide surface and the third guide surface are guided by a first wall and the second guide surface and the fourth guide surface are guided by a second wall. As a result, the electrical interface on the board of the consumable cartridge contacts a contact of the mounting portion properly.
- If the board is positioned offset from the board supporting portion in the fifth direction, the board contacts the first wall during the insertion of the consumable cartridge into the mounting portion. Similarly, if the board is positioned offset from the board supporting portion in the sixth direction, the board contacts the second wall during the insertion of the consumable cartridge into the mounting portion. Therefore, if the board is offset from the board supporting portion in the fifth direction or the sixth direction, the consumable cartridge cannot be mounted to the mounting portion.
- An electrical interface of the board which is supported on the board supporting portion at a right position can contact the contact of the mounting portion while an electrical interface of the board which is offset from the board in the fifth direction and the sixth direction cannot contact the contact of the mounting portion. As a result, the electrical interface of the consumable cartridge and the contact of the mounting portion can securely contact each other.
- Optionally, the first guide surface is positioned further in the fifth direction than the board, or positioned at the same position as an end of the board in the fifth direction, wherein the second guide surface is positioned further in the sixth direction than the board, or positioned at the same position as an end of the board in the sixth direction.
- The first wall is guided by the first guide surface and the second wall is guided by the second guide surface while the board is not damaged by the first wall and the second wall.
- Optionally, the third guide surface and the fourth guide surface extend beyond the electrical interface in the third direction.
- With this configuration, when the liquid cartridge contacts something, the board is protected by the third guide surface and the fourth guide surface. A likelihood that the board is damaged can be reduced.
- Optionally, the first guide surface and the third guide surface are staggered along the first direction and the second direction, and the second guide surface and the fourth guide surface are staggered along the first direction and the second direction. Optionally, when viewed in the fifth direction or the sixth direction, at least a portion of the third guide surface does not overlap a portion of the board, which portion contacts the board supporting portion, and at least a portion of the fourth guide surface does not overlap the portion of the board.
- With this configuration, if the board contacts the board supporting portion via ultraviolet curable adhesive, the optical path of the ultraviolet light directed toward the ultraviolet curable adhesive applied between the board and the board supporting portion cannot be blocked when the consumable cartridge is manufactured. Therefore, the manufacture of the consumable cartridge becomes easy.
- Optionally, the consumable cartridge further comprises a first protrusion and a second protrusion positioned away from each other in the fifth direction and the sixth direction, wherein the first protrusion and the second protrusion protrude in the fourth direction.
- With this configuration, a likelihood is reduced that the consumable cartridge rotates around an axis extending in the first direction when the mounting of the consumable cartridge to the mounting portion is completed. Therefore, the electrical interface contacts the contact of the mounting portion further securely.
- Optionally, the first protrusion is positioned further in the fifth direction than the board, and the second protrusion is positioned further in the sixth direction than the board.
- With this configuration, the distance between the first protrusion and the second protrusion becomes larger, and therefore the rotation of the consumable cartridge is further suppressed.

The left end of thelock portion 145 is fixed at the left end wall of thecase 101, and the right end of thelock portion 145 is fixed at the right end wall of thecase 101. Thelock portion 145 does not move relative to thecase 101, e.g., does not pivot relative to thecase 101. Thelock portion 145 extends over the four spaces into which the fourcartridges 30 are mountable, respectively. A space is formed around thelock portion 145 in each of the four spaces. Therefore, thelock portion 145 is accessible in theupward direction 54 and in theremoval direction 52. - The
lock portion 145 is used for locking theink cartridge 30 in the mounted position when theink cartridge 30 is mounted to thecartridge mounting portion 110. When theink cartridge 30 is inserted into thecartridge mounting portion 110 and pivots to the mounted attitude as an example of the first attitude, theink cartridge 30 contacts thelock portion 145 in theremoval direction 52, and thelock portion 145 locks or retains theink cartridge 30 against the urging force from theslider 107, which urging force urges theink cartridge 30 in theremoval direction 52, and against an urging force of acoil spring 78 of theink cartridge 30, which urging force also urges theink cartridge 30 in theremoval direction 52. - Referring to

Theink cartridge 30 comprises aninner frame 35, arear cover 31, and afront cover 32. Therear cover 31 and thefront cover 32 are attached to each other, and theinner frame 35 is enclosed by therear cover 31 and thefront cover 32. Therear cover 31 and thefront cover 32 forms the outer shape of theink cartridge 30. Theink chamber 36 is formed in theinner frame 35. In another embodiment, theink cartridge 35 may not have theinner frame 35, and therear cover 31 and thefront cover 32 may define theink chamber 36. - The attitude of the
ink cartridge 30 shown inFigs. 1 ,3 and4 is the mounted attitude, as an example of the first attitude. As described below, theink cartridge 30 comprises afront face 140, arear face 41, anupper face lower face side face side face ink cartridge 30. When theink cartridge 30 takes the attitude shown inFigs. 1 ,3 and4 , the direction extending from therear face 41 tofront face 140 coincides with theinsertion direction 51, the direction extending from thefront face 140 to therear face 41 coincides with theremoval direction 52, the direction extending from theupper face lower face downward direction 53, the direction extending from thelower face upper face upward direction 54. When theink cartridge 30 is inserted into and mounted to thecartridge mounting portion 110, thefront face 140 faces theinsertion direction 51, therear face 41 faces theremoval direction 52, thelower face downward direction 53, and theupper face upward direction 54. - Referring to
Figs. 3 and4 , theink cartridge 30 has a width dimension along theright direction 55 and theleft direction 56, a height dimension along thedownward direction 53 and theupward direction 54, a depth dimension along theinsertion direction 51 and theremoval direction 52. The width dimension is less than each of the height dimension and the depth dimension. Thefront cover 32 comprises thefront face 140, which faces theinsertion direction 51 when theink cartridge 30 is inserted into thecartridge mounting portion 110, and therear cover 31 comprises therear face 41, which faces theremoval direction 52 when theink cartridge 30 is inserted into thecartridge mounting portion 110. Theink chamber 36 is positioned between thefront face 140 and therear face 41. - Referring to

The side faces 37, 38 face theright direction 55 and theleft direction 56, respectively, theupper face 39 faces theupward direction 54, and thelower face 42 faces thedownward direction 53. The side faces 37, 38, theupper face 39, and thelower face 42 extend from therear face 41 in theinsertion direction 51, and the inner space of therear cover 31 is opened toward theinsertion direction 51. Theinner frame 35 is inserted into the inner space of therear cover 31 from the opening, i.e., therear cover 31 covers a rear portion of theinner frame 35. Theink chamber 36 is positioned between theupper face 39 and thelower face 42. - Referring to
Figs. 3 and4 , therear cover 31 comprises aprotrusion 43 extending from theupper face 39. Theprotrusion 43 is positioned at about the center of theupper face 39 in theright direction 55 and theleft direction 56, and extends in theinsertion direction 51 and theremoval direction 52. Theprotrusion 43 comprises alock surface 151 facing theremoval direction 52. Thelock surface 151 extends in theupward direction 54 and thedownward direction 53. Thelock surface 151 is configured to contact thelock portion 145 of thecartridge mounting portion 110 in theremoval direction 52 when the ink cartridge is mounted to thecartridge mounting portion 110. By thelock surface 151 contacting thelock portion 145 in theremoval direction 52, theink cartridge 30 is locked or retained in thecartridge mounting portion 110 against the urging force of the pullingspring 114 transmitted via theslider 107 and the urging force of thecoil spring 78. - The
protrusion 43 comprises aninclined surface 155 in front of thelock surface 151, i.e., positioned further in theinsertion direction 51 than thelock surface 151. Theinclined surface 155 faces theupward direction 54 and theinsertion direction 51. Therefore, theinclined surface 155 is viewable when theink cartridge 30 is viewed in thedownward direction 53 and is viewable when the ink cartridge is viewed in theremoval direction 52. During the insertion of theink cartridge 30 into thecartridge mounting portion 110, thelock portion 145 of thecartridge mounting portion 145 slides on theinclined surface 155 and therefore is smoothly guided to a position more rearward than thelock surface 151, i.e., a position further in theremoval direction 52 than thelock surface 151. - The
rear cover 31 comprises anoperation portion 90 at theupper face 39, and theoperation portion 90 is positioned more rearward than thelock surface 151, i.e., positioned further in theremoval direction 52 than thelock surface 151. Theupper face 39 comprises a subupper face 91 positioned at the rear end of theupper face 39. The subupper face 91 is positioned below the rest of theupper face 39, i.e., the subupper face 91 is positioned further in thedownward direction 53 than the rest of theupper face 39. Theoperation portion 90 is positioned above the subupper face 91, i.e., theoperation portion 90 is positioned further in theupward direction 54 than the subupper face 91, with a space formed therebetween. Theoperation portion 90 extends in theupward direction 54 beyond theprotrusion 43 from a position adjacent to the boundary between the subupper face 91 and the rest of theupper face 39, and then extends obliquely downward, i.e., in theremoval direction 52 and thedownward direction 53. - The
operation portion 90 comprises anoperation surface 92 facing theupward direction 54 and theremoval direction 52. The position of theoperation surface 92 and the position of the subupper face 91 along theinsertion direction 51 and theremoval direction 52 at least partly overlap. In other words, theoperation surface 92 and the subupper face 91 at least partly overlap in thedownward direction 53 and theupward direction 54. In other words, at least a portion of theoperation surface 92 is aligned with at least a portion of the subupper face 91 in thedownward direction 53 and theupward direction 54. Theoperation surface 92 comprises a plurality of protrusions, i.e., a plurality of elongated protrusions, each extending in theright direction 55 and theleft direction 56. The elongated protrusions are spaced apart from each other in theinsertion direction 51 and therearward direction 52. With the elongated protrusions, theoperation surface 92 becomes recognizable to a user, and theoperation surface 92 becomes nonskid when the user operates theoperation surface 92 with his/her finger. - The
operation surface 92 is viewable when theink cartridge 30 is viewed in thedownward direction 53 and when theink cartridge 30 is viewed in theinsertion direction 51. In other words, theoperation surface 92 is viewable when theink cartridge 30 is viewed in the direction extending from theupper face 39 toward thelower face 42 and when theink cartridge 30 is viewed in the direction extending from therear face 41 toward thefront face 140. Theoperation surface 92 is a surface a user operates for unlocking or releasing theink cartridge 30 from the locked state in thecartridge mounting portion 110. Theoperation portion 90 is fixed to therear cover 31, e.g., theoperation portion 90 is integrally molded with therear cover 31, and therefore theoperation portion 90 does not move relative to therear cover 31, e.g., does not pivot relative to therear cover 31. Therefore, a force applied to theoperation surface 92 from a user is directly transmitted to therear cover 31, without changing its direction. In this embodiment, theoperation portion 90 also does not move relative to theinner frame 35 orink chamber 36, e.g., does not pivot relative to theinner frame 35 orink chamber 36. - At least a portion of the
operation surface 92 protrudes further in theupward direction 54 than thelock surface 151. - Referring to
Figs. 3 and4 , thefront cover 32 has a box shape having side faces 143, 144 spaced apart from each other in theright direction 55 and theleft direction 56, theupper face 141 and thelower face 142 spaced apart from each other in thedownward direction 53 and theupward direction 54, and thefront face 140. The side faces 143, 144 face theright direction 55 and theleft direction 56, respectively, theupper face 141 faces theupward direction 54, and thelower face 142 faces thedownward direction 53. The side faces 143, 144, theupper face 141, and thelower face 142 extend from thefront face 140 in theremoval direction 52, and the inner space of thefront cover 32 is opened toward theremoval direction 52. Theinner frame 35 is inserted into the inner space of thefront cover 32 from the opening. Thefront cover 32 covers a front portion of theinner frame 35, which is not covered by therear cover 31. Theink chamber 36 is positioned between theupper face 141 and thelower face 142. - The
upper face 141 of thefront cover 32 and theupper face 39 of therear cover 31 constitute the upper face of theink cartridge 30. Thelower face 142 of thefront cover 32 and thelower face 42 of therear cover 31 constitute the lower face of theink cartridge 30. The side faces 143, 144 of thefront cover 32 and the side faces 37, 38 of therear cover 31 constitute the side faces of theink cartridge 30. Thefront face 140 of thefront cover 32 constitutes the front face of theink cartridge 30, and therear face 41 of therear cover 31 constitutes the rear face of theink cartridge 30. - Each of the front face, the rear face, the upper face, the lower face, and the side faces of the

Thesecond protrusion 86 is positioned below theink supply portion 34, i.e., positioned further in thedownward direction 53 than theink supply portion 34. Theprotrusion 86 has arecess 87 formed in its lower face, and therecess 87 opens in theinsertion direction 51 and thedownward direction 53. A portion of thesecond protrusion 86 defining therecess 87 extends beyond thelower face 142 of thefront cover 32 in thedownward direction 53. During the insertion of theink cartridge 30 into thecartridge mounting portion 110, theslider 107 enters therecess 87 and contacts the portion of thesecond protrusion 86 defining therecess 87. - Although not shown in the drawings in detail, the
inner frame 35 comprises an annular or loop shaped wall, and the inner space surrounded by the wall opens in theright direction 55 and theleft direction 56 at the right and left ends of theinner frame 35, respectively. Films (not shown) are attached to the right and left ends of theinner frame 35, such that the inner space of theinner frame 35 is closed, and the inner space becomes theink chamber 36 configured to store ink therein. Theinner frame 35 comprises afront face 40, and theink supply portion 34 is positioned at thefront face 40. Thefront face 40 of theinner frame 35 is positioned adjacent to thefront face 140 of thefront cover 32, when theinner frame 35 is inserted into thefront cover 32. - Referring to
Fig. 4 , theink supply portion 34 extends from thefront face 40 of theinner frame 35 in theinsertion direction 51 to the outside of thefront cover 32 through theopening 97 formed through thefront face 140 of thefront cover 32. Theink supply portion 34 has a circular cylindrical outer shape. Theink supply portion 34 comprises thecylindrical wall 73 having a circular cylindrical shape having an inner space, aseal member 76, and acap 79. Theseal member 76 and thecap 79 are attached to thecylindrical wall 73. - The
cylindrical wall 73 extends from the inside of theink chamber 36 to the outside of theink chamber 36. The inner space of thecylindrical wall 73 opens to theink chamber 36 at the rear end of thecylindrical wall 73. The inner space of thecylindrical wall 73 opens to the outside of theink cartridge 30 at the front end of thecylindrical wall 73. Communication between theink chamber 36 and the outside of theink cartridge 30 is allowed via the inner space of thecylindrical wall 73. Theink supply portion 34 is configured to supply ink stored in theink chamber 36 to the outside of theink cartridge 30 through the inner space of thecylindrical wall 73. Theseal member 76 and thecap 79 are attached to the front end of thecylindrical wall 73. - The
ink supply portion 34 comprises thevalve 77 and thecoil spring 78 positioned in the inner space of thecylindrical wall 73. Thevalve 77 and thecoil spring 78 are configured to switch the state of theink supply portion 34 between a state in which ink is allowed to flow out of theink chamber 30 through the inner space of thecylindrical wall 73 to the outside of the ink cartridge 30 (seeFigs. 8 and9 ) and a state in which ink is prevented from flowing out of the inner space of thecylindrical wall 73 to the outside of the ink cartridge 30 (seeFigs. 6 and7 ). - The
valve 77 is configured to move in theinsertion direction 51 and theremoval direction 52 to selectively open and close theink supply opening 71 formed through the center of theseal member 76. Thecoil spring 78 is configured to urge thevalve 77 in theinsertion direction 51, such that thevalve 77 contacts theseal member 76 and close theink supply opening 71 when an external force is not applied to thevalve 77. - The
seal member 76 is positioned at the front end of thecylindrical wall 73. Theseal member 76 has substantially a disc shape having theink supply opening 71 formed therethrough in theinsertion direction 51 and theremoval direction 52. Theseal member 76 is made of an elastic material such as rubber, elastomer, etc. The diameter of theink supply opening 71 is slightly less than the outer diameter of theink supply tube 102. Theseal member 76 liquid-tightly contacts the front end of thecylindrical wall 73 while being pressed by thecap 79 which is attached to and covers the outside of thecylindrical wall 73. - Before the
ink cartridge 30 is inserted into thecartridge mounting portion 110, thevalve 77 closes theink supply opening 71. When theink cartridge 30 is inserted into thecartridge mounting portion 110, theink supply tube 102 enters theink supply opening 71. When this occur, the inner surface of theseal member 76 defining theink supply opening 71 liquid-tightly contacts the outer surface of theink supply tube 102 while theseal member 76 is elastically deformed by the outer surface of theink supply tube 102. When theink cartridge 30 is further inserted, the end of theink supply tube 102 passes through theink supply opening 71 and contacts thevalve 77. When theink cartridge 30 is further inserted, theink supply tube 102 pushes and moves thevalve 77 in theremoval direction 52 against the urging force of thecoil spring 78. When this occurs, ink is allowed to flow from theink chamber 36 to theink supply tube 102 through the inner space of thecylindrical wall 73. Although not shown in the drawings, theink supply tube 102 has an opening at or adjacent to the end of theink supply tube 102, and the opening extends from the outer surface of theink supply tube 102 to the inner space of theink supply tube 102. Ink flows from the inner space of thecylindrical wall 73 to the inner space of theink supply tube 102 via the opening of theink supply tube 102. Ink flows from theink chamber 36 to the outside of theink cartridge 30 through the inner space of thecylindrical wall 73 and the inner space of theink supply tube 102. - The
ink supply portion 34 may not necessarily comprise thevalve 77 and thecoil spring 78. For instance, in another embodiment, theink supply opening 71 may be closed by a film. In such an embodiment, when theink cartridge 30 is inserted into thecartridge mounting portion 110, theink supply tube 102 penetrates through the film and passes through theink supply opening 71, such that the end of theink supply tube 102 is positioned in the inner space of thecylindrical wall 73. In yet another embodiment, theink supply opening 71 may be closed by the elasticity of theseal member 76. In such an embodiment, when theink cartridge 30 is inserted into thecartridge mounting portion 110, the outer surface of theink supply tube 102 pushes the inner surface of theseal member 76 defining theink supply opening 71 radially, and thereby opens theink supply opening 71. - Referring to

In other words, the contact portion of theIC board 64 is viewable through therecess 176 when theink cartridge 30 is viewed in theright direction 55. - In another embodiment, the
third wall 173 may be positioned further in theinsertion direction 51 than thefirst guide surface 131, and thefourth wall 174 may be positioned further in theinsertion direction 51 than thesecond guide surface 132. Alternatively, thethird wall 173 may be positioned further in theremoval direction 52 than thefirst guide surface 131, and thefourth wall 174 may be positioned further in theremoval direction 52 than thesecond guide surface 132. Alternatively, thethird wall 173 may be positioned further in theinsertion direction 51 than thefirst guide surface 131, and thefourth wall 174 may be positioned further in theremoval direction 52 than thesecond guide surface 132. - The
third wall 173 is spaced away from theboard supporting portion 130 in theright direction 55 and thefourth wall 174 is spaced away from theboard supporting portion 130 in theleft direction 56. Therefore, when theink cartridge 30 is inserted into thecartridge mounting portion 110, afirst space 181 is formed between thethird wall 173 and theboard supporting portion 130 and asecond space 182 is formed between thefourth wall 174 and theboard supporting portion 130. Thefirst space 181 receives thefirst wall 161 of thecartridge mounting portion 110 and thesecond space 182 receives thesecond wall 162 of thecartridge mounting portion 110. - The right end of the
first space 181 is defined by thethird guide surface 133, and the left end of thefirst space 181 is defined by thefirst guide surface 131. Thefirst space 181 is opened in theinsertion direction 51 and theupward direction 54. Thefirst space 181 extends up to a position further in theremoval direction 52 than theIC board 64. Thefirst space 181 is large enough to receive thefirst wall 161. - When the

Figs. 4 and10 , theink cartridge 30 comprises twoprotrusions first protrusion 85. Theprotrusion 137 is an example of a first protrusion and theprotrusion 138 is an example of a second protrusion. Theprotrusions right direction 55 and theleft direction 56. Eachprotrusion first protrusion 85 in thedownward direction 53 and extends in theinsertion direction 51 and theremoval direction 52. Theprotrusion 137 is positioned further in theright direction 55 than theprotrusion 138. - The
protrusion 137 is positioned further in theright direction 55 than theIC board 64. Theprotrusion 138 is positioned further in theleft direction 56 than theIC board 64. - The
protrusion 137 is positioned between theboard supporting portion 130 and thethird wall 173. Theprotrusion 137 is positioned between both ends of thethird wall 173 in theinsertion direction 51 and theremoval direction 52. Therefore, theprotrusion 137 overlaps thefirst space 181 when viewed in theupward direction 54 or thedownward direction 53. In this embodiment, theprotrusion 137 entirely overlaps thefirst space 181. In another embodiment, theprotrusion 137 partly overlaps thefirst space 181. - The
protrusion 138 is positioned between theboard supporting portion 130 and thefourth wall 174. Theprotrusion 138 is positioned between both ends of thefourth wall 174 in theinsertion direction 51 and theremoval direction 52. Therefore, the protrusion 1387 overlaps thesecond space 182 when viewed in theupward direction 54 or thedownward direction 53.

Fig. 12 , theprotrusions support plate 126 of thecartridge mounting portion 110 from above when the mounting of theink cartridge 30 to thecartridge mounting portion 110 is completed. More specifically, theprotrusion 137 contacts theprotrusion 127 of thesupport plate 126, and theprotrusion 138 contacts theprotrusion 128 of thesupport plate 126. - The
protrusions protrusions protrusions first protrusion 85 from below. Theprotrusions protrusions protrusions support plate 126. When both theprotrusions protrusions first protrusion 85 contacts the upper surface of thesupport plate 126. - Referring to
Fig. 4 , before theink cartridge 30 is inserted into thecartridge mounting portion 110, thevalve 77 closes theink supply opening 71. The flow of ink from theink chamber 36 to the outside of theink cartridge 30 is blocked. - Referring to
Fig. 5 , theink cartridge 30 is inserted into thecase 101 via theopening 112 of thecartridge mounting portion 110. A user pushes therear face 41 of therear cover 31 to insert theink cartridge 30 in theinsertion direction 51 into thecartridge mounting portion 110. A lower portion of thefront cover 32 is positioned in theguide groove 109 of the lower portion of thecase 101. - Referring to
Fig. 6 , when theink cartridge 30 is further inserted into thecartridge mounting portion 110, theslider 107 enters therecess 87 and contacts thesecond protrusion 86 of theink cartridge 30. - Referring to
Fig. 7 , when theink cartridge 30 is further inserted in theinsertion direction 51 against the urging force of the pullingspring 114 urging theslider 107 in theremoval direction 52, thecap 79 of theink supply portion 34 starts to enter theguide portion 105, and therod 125 starts to enter therecess 96. - Referring to
Fig. 8 , when theink cartridge 30 is further inserted in theinsertion direction 51 against the urging force of the pullingspring 114 urging theslider 107 in theremoval direction 52, theink supply tube 102 enters theink supply opening 71 and pushes thevalve 77 away from theseal member 76 against the urging force of thecoil spring 78. The urging force of the pullingspring 114 is applied to theink cartridge 30 via theslider 107 in theremoval direction 52, and the urging force of thecoil spring 78 is applied to theink cartridge 30 in theremoval direction 52. - The
rod 125 is further inserted into therecess 96. Theprotrusion 137 contacts theprotrusion 127 and theprotrusion 138 contacts theprotrusion 128. With this contact, the movement of thefirst protrusion 85 in thedownward direction 53 is restricted. - The
first wall 161 and thesecond wall 162 of themain body 163 of thecontact unit 160 enter thefirst space 181 and thesecond space 182, respectively. While thefirst guide surface 131 and thethird guide surface 133 are guided by thefirst wall 161 and thesecond guide surface 132 and thefourth guide surface 134 are guided by thesecond wall 162, theIC board 64 reaches a position directly below thecontacts 106. Until theIC board 64 reaches the position below thecontacts 106, the lower ends of thecontacts 106 are positioned further in thedownward direction 53 than the upper surface of theelectrodes 65. When theIC board 64 reaches the position below thecontacts 106,IC board 65 pushes up thecontacts 106 in theupward direction 54, and thecontacts 106 are elastically deformed in theupward direction 54. As such, theelectrodes 65 contact the correspondingcontacts 106. When this occurs, electrical connection between the IC (not shown) of theIC board 64 and thecontroller 1 is established, and thecontroller 1 becomes able to access the IC. - When the
electrodes 65 contact thecontacts 106, theIC board 64 is urged in thedownward direction 53 by the elasticallydeformed contacts 106. Nevertheless, because theprotrusions first protrusion 85 contact theprotrusions support plate 126, respectively, the movement of thefirst protrusion 85 in thedownward direction 53 is restricted. Therefore, theIC board 64 is accurately positioned relative to thecontacts 106 in thedownward direction 53 and theupward direction 54. - The
protrusion 43 of therear cover 31 reaches thelock portion 145, and theinclined surface 155 slides on thelock portion 145. The sliding contact between theinclined surface 155 and thelock portion 145 causes theink cartridge 30 to pivot clockwise inFig. 8 about a pivot center which is the center of theink supply opening 71 through which theink supply tube 102 is inserted. The attitude of theink cartridge 30 inFig. 8 is an example of a second attitude. When theink cartridge 30 is in the second attitude, thelock surface 151 of theprotrusion 43 is positioned below thelock portion 145, i.e., positioned further in thedownward direction 53 than thelock portion 145. - Referring to
Fig. 9 , when theink cartridge 30 is further inserted in theinsertion direction 51 against the urging force of the pullingspring 114 urging theslider 107 in theremoval direction 52 and against urging force of thecoil spring 78, theinclined surface 155 is positioned further in theinsertion direction 51 than thelock portion 145. When theinclined surface 155 does not contact thelock portion 145, theink cartridge 30 pivots counterclockwise inFig. 9 about the pivot center which is the center of theink supply opening 71 through which theink supply tube 102 is inserted. - When the
ink cartridge 30 pivots counterclockwise, thelock surface 151 reaches a position in which thelock surface 151 and thelock portion 145 face each other in theinsertion direction 51 and theremoval direction 52. Moreover, when theink cartridge 30 pivots counterclockwise, therear cover 31 contacts thelock portion 145. When this occurs, the impact of the contact tells the user that the insertion of theink cartridge 30 is completed. When the user stops pushing theink cartridge 30, theink cartridge 30 is moved in theremoval direction 52 by the urging force of the pullingspring 114 applied via theslider 107 and the urging force of thecoil spring 78. When this occurs, thelock surface 151 contacts thelock portion 145 in theremoval direction 52 and the movement of theink cartridge 30 relative to thecartridge mounting portion 110 in theremoval direction 52 is restricted, as shown inFig. 9 . The attitude of theink cartridge 30 inFig. 9 is an example of the first attitude. The mounting of theink cartridge 30 to thecartridge mounting portion 110 is thus completed. Theink cartridge 30 is locked or retained in thecartridge mounting portion 110 with thelock surface 151 contacting thelock portion 145 in theremoval direction 52 against the urging force of the pullingspring 114 and the urging force of thecoil spring 78 in theremoval direction 52. - When the mounting of the
ink cartridge 30 to thecartridge mounting portion 110 is completed, theprotrusion 127 is positioned further in theright direction 55 than theIC board 64. Theprotrusion 128 is positioned further in theleft direction 56 than theIC board 64. - When the mounting of the
ink cartridge 30 to thecartridge mounting portion 110 is completed, theprotrusion 127 is positioned between theboard supporting portion 130 and thethird wall 173. Theprotrusion 127 is positioned between both ends of thethird wall 173 in theinsertion direction 51 and theremoval direction 52. Therefore, theprotrusion 127 overlaps thefirst space 181 when viewed in theupward direction 54 or thedownward direction 53. In this embodiment, theprotrusion 127 entirely overlaps thefirst space 181. In another embodiment, theprotrusion 127 partly overlaps thefirst space 181. - When the mounting of the
ink cartridge 30 to thecartridge mounting portion 110 is completed, theprotrusion 128 is positioned between theboard supporting portion 130 and thefourth wall 174. Theprotrusion 128 is positioned between both ends of thefourth wall 174 in theinsertion direction 51 and theremoval direction 52. Therefore, theprotrusion 128 overlaps thesecond space 182 when viewed in theupward direction 54 or thedownward direction 53. In this embodiment, theprotrusion 128 entirely overlaps thesecond space 182. In another embodiment, theprotrusion 128 partly overlaps thesecond space 182. - When a user wishes to remove the
ink cartridge 30 from thecartridge mounting portion 110, the user pushes down theoperation surface 92. When theink cartridge 30 is in the first attitude, theoperation surface 92 is viewable when theink cartridge 30 is viewed in thedownward direction 53 and is viewable when theink cartridge 30 is viewed in theinsertion direction 51. In other words, when theink cartridge 30 is in the first attitude, theoperation surface 92 faces theupward direction 54 and theremoval direction 52. Therefore, when the user pushes theoperation surface 92 when theink cartridge 30 is in the first attitude to release theink cartridge 30, the user's force is directed toward thedownward direction 53 and theinsertion direction 51. Due to the force directed toward theinsertion direction 51, thelock surface 151 separates from thelock portion 145. Due to the force directed toward thedownward direction 53, theink cartridge 30 pivots from the first attitude to the second attitude. Therefore, compared to a situation in which theink cartridge 30 pivots from the first attitude to the second attitude while thelock surface 151 slides on thelock portion 145, the force needed to be applied to theoperation surface 92 to cause theink cartridge 30 to pivot from the first attitude to the second attitude becomes smaller, and the user can readily release theink cartridge 30. - When the
ink cartridge 30 pivots from the first attitude to the second attitude, thelock surface 151 is positioned below thelock portion 145, i.e., positioned further in thedownward direction 53 than thelock portion 145. The urging force of the pullingspring 114 and thecoil spring 78 moves theink cartridge 30 in theremoval direction 52. When theink cartridge 30 separates from theslider 107, the urging force is no longer applied to theink cartridge 30, and theink cartridge 30 stops moving in theremoval direction 52. When this occurs, at least therear cover 31 of theink cartridge 30 is positioned outside of thecase 101, the user can take theink cartridge 30 out of thecartridge mounting portion 110. - According to the above-described embodiment, the
ink cartridge 30 is inserted into thecartridge mounting portion 110 and mounted to thecartridge mounting portion 110 while thefirst guide surface 131 is guided by thefirst wall 161 and thesecond guide surface 132 is guided by thesecond wall 162. As a result, theelectrodes 65 of theIC board 64 of theink cartridge 30 contact thecontacts 106 of thecartridge mounting portion 110, respectively. - Referring to
Fig. 13A , if theIC board 64 is positioned offset from theboard supporting portion 130 in theright direction 55, theIC board 64 contacts thefirst wall 161 during the insertion of theink cartridge 30 into thecartridge mounting portion 110. Similarly, referring toFig. 13B , if theIC board 64 is positioned offset from theboard supporting portion 130 in theleft direction 56, theIC board 64 contacts thesecond wall 162 during the insertion of theink cartridge 30 into thecartridge mounting portion 110. Therefore, if theIC board 64 is offset from theboard supporting portion 130 in theright direction 55 or theleft direction 56, theink cartridge 30 cannot be mounted to thecartridge mounting portion 110. - The
electrodes 65 of theIC board 64 which is supported on theboard supporting portion 130 at an accurate position can contact thecontacts 106 of thecartridge mounting portion 110 while theelectrodes 65 of theIC board 64 which is offset from theboard supporting portion 130 in theright direction 55 or theleft direction 56 cannot contact thecontacts 106 of thecartridge mounting portion 110. As a result, theelectrodes 65 of theink cartridge 30 and thecontacts 106 of thecartridge mounting portion 110 can securely contact each other. - Incidentally, when the mounting of the
ink cartridge 30 to thecartridge mounting portion 110 is completed, theIC board 64 may overlap thefirst wall 161 and thesecond wall 162 when viewed in theright direction 55 or theleft direction 56, or may be positioned further in theinsertion direction 51 than thefirst wall 161 and thesecond wall 162. - Because the
first guide surface 131 is positioned further in theright direction 55 than theIC board 64, or positioned at the same position as the end of theIC board 64 in theright direction 55, and thesecond guide surface 132 is positioned further in theleft direction 56 than theIC board 64, or positioned at the same position as the end of theIC board 64 in theleft direction 56, theIC board 64 is not damaged by thefirst wall 161 and thesecond wall 162 when thefirst wall 161 is guided by thefirst guide surface 131 and thesecond wall 162 is guided by thesecond guide surface 132. - Because the
ink cartridge 30 is inserted into thecartridge mounting portion 110 and mounted to thecartridge mounting portion 110 while thefirst guide surface 131 and thethird guide surface 133 are guided by thefirst wall 161 and thesecond guide surface 132 and thefourth guide surface 134 are guided by thesecond wall 162, theelectrodes 65 of theink cartridge 30 contact thecontacts 106 of thecartridge mounting portion 110 properly. - Because the
third wall 173 and thefourth wall 174 extend beyond theelectrodes 65 in theupward direction 54, when theink cartridge 30 contacts something, theIC board 64 is protected by thethird wall 173 and thefourth wall 174. A likelihood that theIC board 64 is damaged can be reduced. - The
first guide surface 131 and thethird guide surface 133 are staggered along theinsertion direction 51 and theremoval direction 52, and thesecond guide surface 132 and thefourth guide surface 134 are staggered along theinsertion direction 51 and theremoval direction 52. When viewed in theright direction 55 or theleft direction 56, at least a portion of thethird wall 173 does not overlap the contact portion of theIC board 64, and at least a portion of thefourth wall 174 does not overlap the contact portion of theIC board 64. Therefore, if theIC board 64 contacts theboard supporting portion 130 via ultraviolet curable adhesive, the optical path of the ultraviolet light directed toward the ultraviolet curable adhesive applied on the contact portion of theIC board 64 in theright direction 55 or theleft direction 56 is not blocked when theink cartridge 30 is manufactured. Therefore, the manufacture of theink cartridge 30 becomes easy. - Because the dimension L1 of the
electrode 65 is greater than the sum of L2 and L3 and greater than the sum of L4 and L5, when thefirst wall 161 and thesecond wall 162 move in thefirst space 181 and thesecond space 182 in theright direction 55 and theleft direction 56, theelectrodes 65 still remains in contact with thecontacts 106 of thecartridge mounting portion 110. - Because the
protrusion 137 contacts theprotrusion 127 and theprotrusion 138 contacts theprotrusion 128 when the mounting of theink cartridge 30 to thecartridge mounting portion 110 is completed, a likelihood is reduced that theink cartridge 30 rotated around an axis extending in theinsertion direction 51. Therefore, theelectrodes 65 contact thecontacts 106 of thecartridge mounting portion 110 further securely. - When the distance between the
protrusion 127 and theprotrusion 128 or between theprotrusion 137 and theprotrusion 138 in theright direction 55 and theleft direction 56 becomes larger, the rotation of theink cartridge 30 is further suppressed. - When the
controller 1 accesses the IC of theIC board 64 via theelectrodes 65 and thecontacts 106, thecontroller 1 can read data out of the IC, or write date in the IC, or both. - In the above-described embodiment, the
third guide surface 133 and thefourth guide surface 134 are provided to theink cartridge 30. Nevertheless, thethird guide surface 133 and thefourth guide surface 134 are optional. Even if thethird guide surface 133 and thefourth guide surface 134 are not provided, theink cartridge 30 is inserted into thecartridge mounting portion 110 and mounted to thecartridge mounting portion 110 while thefirst guide surface 131 is guided by thefirst wall 161 and thesecond guide surface 132 is guided by thesecond wall 162. In such a case, thefirst space 181 is formed to the right of thefirst guide surface 131, and thefirst space 181 is opened in theinsertion direction 51, theupward direction 54, and theright direction 55. Similarly, thesecond space 182 is formed to the left of thesecond guide surface 132, and thesecond space 182 is opened in theinsertion direction 51, theupward direction 54, and theleft direction 56. - In the above-described embodiment, the ink-
jet printer 10 is an example of the system, but the system is not limited to an ink-jet printer. The system can be an electrographic or laser printer configured to record an image on a sheet of paper with toner, applying the electrographic printing method. The system also can be a thermal transfer label printer configured to record an image on a label, applying the thermal transfer printing method. - In the above-described embodiment, ink is an example of the consumable, but the consumable is not limited to the ink. The consumable can be toner or a label used for the electrographic or laser printer and the label printer.
