- the lock surface 151 extends in the upward direction 54 and the downward direction 53.
- the lock surface 151 is configured to contact the lock portion 145 of the cartridge mounting portion 110 in the removal direction 52 when the ink cartridge is mounted to the cartridge mounting portion 110. By the lock surface 151 contacting the lock portion 145 in the removal direction 52, the ink cartridge 30 is locked or retained in the cartridge mounting portion 110 against the urging force of the pulling spring 114 transmitted via the slider 107 and the urging force of the coil spring 78.
- the protrusion 43 comprises reinforcing surfaces 152, 153.
- the reinforcing surfaces 152, 153 are continuous with and extend from the right end and the left end of the lock surface 151 in the right direction 55 and the left direction 56, respectively.
- the reinforcing surfaces 152, 153 extend from a virtual plane toward the insertion direction 51 (the forward direction 57), forming acute angles between the reinforcing surfaces 152, 153 and the virtual plane, respectively, which virtual plane includes the lock surface 151 and extends in the downward direction 53, the upward direction 53, the right direction 55, and the left direction 56.
- the reinforcing surfaces 152, 153 reinforce the strength and the rigidity of the protrusion 43, and therefore a likelihood that the lock surface 151 is damaged is reduced.
- the reinforcing surfaces 152, 153 do not extend more rearward than the lock surface 151, i.e., the reinforcing surfaces 152, 153 do not extend further in the rearward direction 58 than the lock surface 151, the reinforcing surfaces 152, 153 may not contact the lock portion 145 of the cartridge mounting portion 110. Therefore, if the lock surface 145 slides on the lock portion 145, the sliding resistance may not be increased by the reinforcing surfaces 152, 153.
- the protrusion 43 comprises a horizontal surface 154 positioned in front of the lock surface 151, i.e., positioned further in the forward direction 57 than the lock surface 151.

- the inclined surface 155 is viewable when the ink cartridge 30 is viewed in the downward direction 53 and is viewable when the ink cartridge is viewed in the rearward direction 58. Because the horizontal plane 154 is positioned between the lock surface 154 and the inclined surface 155, the lock surface 151 and the inclined surface 155 do not intersect each other at an acute angle. During the insertion of the ink cartridge 30 into the cartridge mounting portion 110, the lock portion 145 of the cartridge mounting portion 145 slides on the inclined surface 155 and the horizontal surface 154 and therefore is smoothly guided to a position more rearward than the lock surface 151, i.e., a position further in the rearward direction 58 than the lock surface 151.
- the protrusion 43 comprises reinforcing surfaces 156, 157.
- the reinforcing surfaces 156, 157 are continuous with and extend from the right end and the left end of the inclined surface 155 in the right direction 55 and the left direction 56, respectively.
- the reinforcing surfaces 156, 157 extend from a virtual plane toward the downward direction 53 forming acute angles between the reinforcing surfaces 156, 157 and the virtual plane, respectively, which virtual plane includes the inclined surface 155 and extends in the right direction 55 and the left direction 56.
- the reinforcing surfaces 156, 157 reinforce the strength and the rigidity of the protrusion 43, and therefore a likelihood that the inclined surface 155 is damaged is reduced.
- the reinforcing surfaces 156, 157 do not extend more upward than the inclined surface 155, i.e., the reinforcing surfaces 156, 157 do not extend further in the upward direction 54 than the inclined surface 155, the reinforcing surfaces 156, 157 may not contact the lock portion 145 of the cartridge mounting portion 110. Therefore, if the inclined surface 155 slides on the lock portion 145, the sliding resistance may not be increased by the reinforcing surfaces 156, 157.

- the operation portion 90 is fixed to the rear cover 31, e.g., the operation portion 90 is integrally molded with the rear cover 31, and therefore the operation portion 90 does not move relative to the rear cover 31, e.g., does not pivot relative to the rear cover 31.

- the central axis 72 of the ink supply opening 71 intersects the center of the ink supply opening 71 and extends in the direction in which the ink supply opening 71 penetrates through the seal member 76, i.e., in the forward direction 57 and the rearward direction 58 in this embodiment.
- the center of the ink supply opening 71 is the center of at least a portion of the ink supply opening 71, and the inner surface of the seal member 76 defining the at least a portion of the ink supply opening 71 contacts the outer surface of the ink supply tube 102 when the ink supply tube 102 is inserted through the ink supply opening 71.
- the center of the ink supply opening 71 is the center of a portion of the ink supply opening 71 defined by the first inner surface, but not by the second inner surface. If the entire inner surface of the seal member 76 contacts the outer surface of the ink supply tube 102, the center of the ink supply opening 71 is the center of the entirety of the ink supply opening 71.
- 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 upper portion 41U of the rear face 41 of the rear cover 31 is positioned more rearward than the lower portion 41L of the rear face 41, i.e., positioned further in the rearward direction 58 than the lower portion 41L of the rear face 41. Therefore, the upper portion 41U is positioned closer to a user than the lower portion 41L is positioned to the user, and the user tends to push the upper portion 41U to insert the ink cartridge 30 in the insertion direction 51 into the cartridge mounting portion 110.
- the upper portion 41U comprises the letter or symbol indicating that the upper portion 41U is supposed to be pushed, the user is urged to push the upper portion 41U.
- a lower portion of the front cover 32 is positioned in the guide groove 109 of the lower portion of the case 101. More specifically, the portion of the second protrusion 86 defining the recess 87 and extending beyond the lower face 142 of the front cover 32 contacts the groove bottom wall of the guide groove 109, and a rear portion of the lower face 142 of the front cover 32 also contacts the groove bottom wall of the guide groove 109. Therefore, a front portion of the front cover 32 is slightly lifted up.
- the slider 107 enters the recess 87 and contacts the second protrusion 86 of the ink cartridge 30. Because the user pushes the upper portion 41U of the rear face 41 of the ink cartridge 30, the ink cartridge 30 pivots counterclockwise in Fig. 8 about the contact point between the slider 107 and the second protrusion 86. When this occurs, the lower face 142 of the front cover 32 moves away from the groove bottom wall of the guide groove 109 of the lower portion of the case 101, and an upper portion of the ink cartridge 30 moves closer to the guide groove 109 of the upper portion of the case 101.
- the ink supply tube 102 enters the ink supply opening 71 and pushes the valve 77 away from the seal member 76 against the urging force of the coil spring 78.
- the urging force of the pulling spring 114 is applied to the ink cartridge 30 via the slider 107 in the removal direction 52, and the urging force of the coil spring 78 is applied to the ink cartridge 30 in the removal direction 52.
- the rod 125 in the recess 96 supports the front cover 32 from below.
- the IC board 64 reaches a position below the contacts 106, and electrodes 65 contact the corresponding contacts 106, respectively, while elastically deforming the contacts 106 in the upward direction 54.
- the IC board 64 is urged in the downward direction 53 by the elastically deformed contacts 106, but the IC board 64 is supported from below by the rod 125. Therefore, the electrodes 65 are accurately positioned relative to the contacts 106 in the upward direction 54 and the downward direction 53. Nevertheless, the rod 125 may not necessarily support the front cover 32.
- the protrusion 43 of the rear cover 31 reaches the lock portion 145, and the inclined surface 155 and the horizontal surface 154 slides on the lock portion 145.
- a counterclockwise moment of force is applied to the ink cartridge 30 because the user pushes the upper portion 41U of the rear face 41 in the insertion direction 51
- the sliding contact between the inclined surface 155 and the lock portion 145 causes the ink cartridge 30 to pivot clockwise about a pivot center O which is the center of the ink supply opening 71 through which the ink supply tube 102 is inserted, i.e., the center of a portion of ink supply tube 102, which portion contacts the inner surface of the seal member 76 defining the ink supply opening 71.
- the attitude of the ink cartridge 30 in Fig. 10 is an example of a second attitude.
- the lock surface 151 is positioned further in the downward direction 53 than the lock portion 145 as shown in Fig. 10 .
- the lock surface 151 may also be positioned further in the removal direction 52 (the rearward direction 58) than the lock portion 145 when the ink cartridge 30 is in the second attitude as shown in Fig. 10 .
- 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 position of the pivot center O and the positions of the electrodes 65 along the insertion direction 51 and the removal direction 52 at least partly overlap. Therefore, the magnitude of a moment of force generated by the urging force of the contacts 106 pushing down the electrodes 65 and applied to the ink cartridge 30 is zero or very small.
- the lower face 42 of the rear cover 31 contacts or is positioned closer to the groove bottom wall of the guide groove 109 of the lower portion of the case 101.
- the lower face 42 when the ink cartridge 30 is in the second attitude, the lower face 42 extends in a horizontal plane.
- the lower portion 41L of the rear face 41 is positioned more forward than the upper portion 41U of the rear face 41, i.e., positioned further in the insertion direction 51 than the upper portion 41U.
- the ink cartridge 30 when the ink cartridge 30 is further inserted in the insertion direction 51 against the urging force of the pulling spring 114 urging the slider 107 in the removal direction 52 and against urging force of the coil spring 78, the inclined surface 155 and the horizontal surface 154 are positioned further in the insertion direction 51 than the lock portion 145. Because the counterclockwise moment of force, which is generated by the user pushing the upper portion 41U of the rear face 41 in the insertion direction 51, is applied to the ink cartridge 30, when the inclined surface 155 and the horizontal surface 154 do not contact the lock portion 145, the ink cartridge 30 pivots counterclockwise about the pivot center O 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. 11 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.
- G is the magnitude of the gravitational force acting on the ink cartridge 30.
- F is the magnitude of the urging force of the pulling spring 114 and the coil spring 78 urging the ink cartridge 30 in the removal direction 52 when the ink cartridge 30 is in the first attitude.
- L is the distance between the center of gravity M of the ink cartridge 30 and the pivot center O along the insertion direction 51 when the ink cartridge 30 is in the second attitude.
- H is the height of the lower end of the upper portion 41U of the rear face 41 from the pivot center O along the upward direction 54 which is perpendicular to the insertion direction 51 when the ink cartridge 30 is in the second attitude.
- Fig. 12 illustrates the ink cartridge 30 when a user pushes the ink cartridge 30 with a force whose magnitude is F as a threshold magnitude required for the ink cartridge 30 to be inserted.
- the user pushes the upper portion 41U of the rear face 41, i.e., pushes a portion above the lower end of the upper portion 41U.
- a force is applied to the portion above the lower end of the upper portion 41U of the ink cartridge 30 in the insertion direction 51, whose magnitude U is greater than the magnitude F of the urging force.
- the upper portion 41U is substantially perpendicular to the insertion direction 51 when the ink cartridge 30 is in the second attitude, a counterclockwise moment of force is applied to the ink cartridge 30, whose magnitude is at least greater than the product FH.
- Fig. 12 illustrates the ink cartridge 30 when a user pushes the lower end of the upper portion 41U of the rear face 41 whose height from the pivot center O along the upward direction 54 is H.
- a clockwise moment of force which is generated by the gravitational force, is applied to the ink cartridge, whose magnitude is the product GL
- the magnitude G of the gravitational force acting on the ink cartridge 30 varies depending on the amount of ink stored in the ink cartridge 30. Nevertheless, if the condition FH > GL is satisfied when a fresh ink cartridge 30 having an initial amount of ink is inserted, the condition is also satisfied when a used ink cartridge 30 whose amount of ink is relatively low is inserted. That is because the product GL becomes smaller as the amount of ink is reduced while the product FH is unchanged.
- the magnitude G is a magnitude of the gravitational force acting on the ink cartridge 30 at least when the ink chamber 36 is completely filled with the initial amount of ink or when ink in the ink chamber 36 is consumed.
- the second protrusion 86 of the ink cartridge 30 receives the urging force of the pulling spring 114 via the slider 107 below the pivot center O, the urging force of the pulling spring 114 also generates an additional moment of force causing the ink cartridge 30 to pivot counterclockwise. Nevertheless, even if the moment of force generated by the pulling spring 114 were not applied to the ink cartridge 30, the overall moment of force applied to the ink cartridge 30 would still be directed counterclockwise.
- the ink cartridge 30 when the ink cartridge 30 is in the first attitude, the upper end of the lock surface 151 is positioned outside of a virtual circle C, and the lower end of the lock surface 151 is positioned within the virtual circle C.
- the virtual circle C has its center at the pivot center O and intersects the lock portion 145. Therefore, when the urging force is applied to the ink cartridge 30 in the removal direction 52 while the lock surface 151 contacts the lock portion 145, the lock portion 145 slides on the lock surface 151 toward the lower end of the lock surface 151. That is, the ink cartridge 30 pivots further counterclockwise when the lock portion 145 and the lock surface 151 contact.
- a user may push the lower portion 41L of the rear face 41 instead of the upper portion 41U of the rear face 41 when the user inserts the ink cartridge 30 into the cartridge mounting portion 110. Nevertheless, because the following condition is satisfied, the ink cartridge 30 can pivot counterclockwise in Fig. 13 : Fcos ⁇ N > GL .
- the lower portion 41L is a plane intersecting a first virtual plane P1 at an angle of ⁇ degrees when the ink cartridge 30 is in the second attitude, and the first virtual plane P1 is perpendicular to the insertion direction 51.
- N is a length of a perpendicular line extending from the pivot center O to a second virtual plane P2 which is perpendicular to the lower portion 41L and intersects the lower end of the lower portion 41L.

- the operation surface 92 faces the upward direction 54 and the rearward direction 58 (the removal direction 52).
- the user's force is directed toward the downward direction 53 and the forward direction 57 (the insertion direction 51). Due to the force directed toward the forward direction 57 (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.
- 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 lower face 142 and the lower face 42 are positioned further in the removal direction 52 than the pivot center O, and the lower face 42 is positioned further in the removal direction 52 than the lower face 142 and is positioned further in the upward direction 54 than the lower face 142. Moreover, the lower face 142 extends in the removal direction 52, and the lower face 42 extends in the removal direction 52 and the upward direction 54.
- a gap is formed between the lower face 142 and the groove bottom wall of the guide groove 109 and between the lower face 42 and the groove bottom wall of the guide groove 109.
- a distance D11 from the lower face 142 (more specifically, the uppermost part of the lower face 142) to the groove bottom wall of the guide groove 109 in the downward direction 53 is less than a distance D12 from the lower face 42 (more specifically, the uppermost part of the lower face 42) to the groove bottom wall of the guide groove in the downward direction 53.
- the lower face 42 and a virtual plane P3 forms an angle of ⁇ degrees therebetween.
- the virtual plane P3 extends from the lower face 142 in the removal direction 52 and is perpendicular to the downward direction 53 and the upward direction 54.
- the ink cartridge 30 pivots between the first attitude and the second attitude by an angle of ⁇ degrees.
- the angle of ⁇ degrees is greater than the angle of ⁇ degrees.
- the rearmost part of the lower face 142 of the front cover 32 becomes the lowermost part of all the parts of the ink cartridge 30. If the lower face 42 and the lower face 142 extended in the same plane, the rearmost part of the lower face 42 would become the lowermost part of all the parts of the ink cartridge 30 when the ink cartridge 30 pivots from the first attitude to the second attitude.
- the rearmost part of the lower face 42 would be positioned further in the downward direction 53 than the rearmost part of the lower face 142 because the rearmost part of the lower face 42 is positioned more remote from the pivot center O than the lower face 142 is.

- the lower face 42 moves in the downward direction 53 more than the lower face 142 because the lower face 42 is positioned more remote from the pivot center O than the lower face 142 is. Nevertheless, because the lower face 42 is positioned further in the upward direction 54 than the lower face 142 when the ink cartridge 30 is in the first attitude, a likelihood is reduced that the lower face 42 contacts the groove bottom wall of the guide groove 109 and the downward movement of the lower face 42 is hindered by the contact.
- the gap is formed between the lower face 142 and the groove bottom wall of the guide groove 109 and between the lower face 42 and the groove bottom wall of the guide groove 109 when the ink cartridge is in the first attitude, a likelihood is further reduced that the lower face 42 contacts the groove bottom wall of the guide groove 109 and the downward movement of the lower face 42 is hindered by the contact.
- the lower face 142 moves in the downward direction 53 less than the lower face 42 because the lower face 142 is positioned closer to the pivot center O than the lower face 42 is. Therefore, a likelihood is reduced that the lower face 142 contacts the groove bottom wall of the guide groove 109 and the downward movement of the lower face 142 is hindered by the contact, although the lower face 142 extends in the removal direction 52.
