Abstract

An object is to provide a technique that enables avoiding of erroneous attachment of multiple cartridges. A cartridge is attachable to a first attachment portion included in a printing apparatus. The cartridge includes a storage portion capable of storing a liquid. The cartridge includes a protruding portion configured to come into contact with another cartridge attempted to be inserted into the first attachment portion in a state where the cartridge is inserted in a second attachment portion adjacent to the first attachment portion.

First claim

What is claimed is:

1 . A cartridge set comprising:
a first cartridge attachable to a first attachment portion included in a printing apparatus; and a second cartridge attachable to a second attachment portion which is included in the printing apparatus and which is adjacent to the first attachment portion, wherein the first cartridge includes a first protruding portion; the second cartridge includes a second protruding portion; the first protruding portion protrudes in a direction away from the second attachment portion in a state where the first cartridge is attached to the first attachment portion, the second protruding portion protrudes in a direction away from the first attachment portion in a state where the second cartridge is attached to the second attachment portion, and one of the first protruding portion and the second protruding portion overlaps the other in a state where the second cartridge is inserted in the first attachment portion and the first cartridge is inserted in the second attachment portion.

2 . The cartridge set according to claim 1 , wherein
the first protruding portion
protrudes in an opposite direction to a direction in which the second attachment portion is located in the state where the first cartridge is attached to the first attachment portion, and
protrudes from the second attachment portion toward the first attachment portion in the state where the first cartridge is inserted in the second attachment portion, and
the second protruding portion
protrudes in an opposite direction to a direction in which the first attachment portion is located in the state where the second cartridge is attached to the second attachment portion, and
protrudes from the first attachment portion toward the second attachment portion in the state where the second cartridge is inserted in the first attachment portion.

3 . The cartridge set according to claim 1 , wherein the first protruding portion is arranged in an upper portion of a side surface of the first cartridge.

4 . The cartridge set according to claim 1 , wherein
the first cartridge further includes
a first storing portion capable of storing a chromatic color ink, and
a first ejection element substrate capable of ejecting the chromatic color ink stored in the first storing portion to a print medium, and
the second cartridge further includes
a second storing portion capable storing an ink of black color, and
a second ejection element substrate capable of ejecting the ink of black color stored in the second storing portion to the print medium.

5 . The cartridge set according to claim 4 , wherein the first protruding portion is arranged in a first lid portion covering an upper portion of the first storing portion.

6 . The cartridge set according to claim 4 , further comprising:
a first connecting portion to which a first tube for supplying the chromatic color ink from a liquid tank included in the printing apparatus to the first storing portion is connectable; and a second connecting portion to which a second tube for supplying the ink of black color from a liquid tank included in the printing apparatus to the second storing portion is connectable.

7 . A printing apparatus comprising:
a first attachment portion to which a first cartridge storing a first type of liquid is attachable; and a second attachment portion to which a second cartridge storing a second type of liquid different from the first type of liquid is attachable, the second attachment portion being adjacent to the first attachment portion, wherein the first cartridge includes a first protruding portion configured to come into contact with the second cartridge attempted to be inserted into the first attachment portion in a state where the first cartridge is inserted in the second attachment portion, and the second cartridge includes a second protruding portion configured to come into contact with the first cartridge attempted to be inserted into the second attachment portion in a state where the second cartridge is inserted in the first attachment portion.

8 . The printing apparatus according to claim 7 , wherein
the first type of liquid is a chromatic color ink, and the second type of liquid is an ink of black color.

9 . The printing apparatus according to claim 7 , wherein
the first protruding portion
protrudes in an opposite direction to a direction in which the second attachment portion is located in a state where the first cartridge is attached to the first attachment portion, and
protrudes from the second attachment portion toward the first attachment portion in the state where the first cartridge is inserted in the second attachment portion, and
the second protruding portion
protrudes in an opposite direction to a direction in which the first attachment portion is located in a state where the second cartridge is attached to the second attachment portion, and
protrudes from the first attachment portion toward the second attachment portion in a state where the second cartridge is inserted in the first attachment portion.

10 . The printing apparatus according to claim 7 , wherein the first protruding portion is arranged in an upper portion of a side surface of the first cartridge.

11 . The printing apparatus according to claim 7 , wherein the first protruding portion is arranged in a first lid portion covering an upper portion of a first storing portion capable of storing the first type of liquid.

12 . The printing apparatus according to claim 7 , further comprising:
a first connecting portion to which a first tube for supplying the first type of liquid from a liquid tank included in the printing apparatus to an inside of the first cartridge is connectable; and a second connecting portion to which a second tube for supplying the second type of liquid from a liquid tank included in the printing apparatus to an inside of the second cartridge is connectable.

13 . The printing apparatus according to claim 7 , further comprising a carriage movable in a scanning direction, the carriage including the first attachment portion and the second attachment portion.

14 . The printing apparatus according to claim 13 , wherein
the carriage includes
a first cover movable between a fixing position where the first cover fixes the first cartridge attached to the first attachment portion and a release position where the first cartridge is released, and
a second cover movable between a fixing position where the second cover fixes the second cartridge attached to the second attachment portion and a release position where the second cartridge is released, wherein
the first cover is configured to be unmovable from the release position to the fixing position in a state where the second cartridge is inserted in the first attachment portion, and the second cover is configured to be unmovable from the release position to the fixing position in a state where the first cartridge is inserted in the second attachment portion.
