Ink cartridge, printer, and method for mounting ink cartridge

A printer comprising:

• a printer body;
• and
• an ink cartridge that is mounted in the printer body, wherein
• the printer body includes
• a cartridge receiving section for receiving the ink cartridge,
• an engaging portion formed on an inner surface of the cartridge receiving section,
• electrical coupling portions provided on the inner surface of the cartridge receiving section, and
• an electronic circuit coupled to the electrical coupling portions, and
• the ink cartridge includes
• a cartridge body configured to contain ink to be supplied to the printer body, including a guide portion having a shape that fits into the cartridge receiving section of the printer body, and configured to be linearly inserted to a first position in which the ink cartridge is in a mounted state in the cartridge receiving section,
• an electronic component mounting section configured to mount an electronic component, and configured to move with respect to the cartridge body in a second direction different from a first direction that is a direction in which the ink cartridge is inserted into the cartridge receiving section,
• a holding portion configured to hold the electronic component mounting section at an initial position in which the electronic component mounting section is in a predetermined positional relationship with the cartridge body when the cartridge body is not inserted into the cartridge receiving section,
• an engaged portion provided on an outer periphery of the cartridge body, and configured to move the electronic component mounting section in the second direction from the initial position by engaging with the engaging portion of the printer body and by the cartridge body being inserted in the first direction from a second position before the first position in the cartridge receiving section of the printer body, and
• coupling bodies configured to couple the electronic component to the electronic circuit of the printer body by coupling to the electrical coupling portions of the printer body with the movement of the electronic component mounting section in the second direction.

A method for mounting, in a printer, an ink cartridge including a cartridge body containing ink and an electronic component mounting section on which an electronic component is mounted, the method comprising:

• holding the electronic component mounting section at an initial position that is a predetermined position to the cartridge body in a state in which the cartridge body is not inserted in a cartridge receiving section provided on a printer side;
• linearly inserting, in the cartridge receiving section of the printer, the cartridge body including a guide portion having a shape that fits into the cartridge receiving section along a first direction, which is an insertion direction of the cartridge body into the cartridge receiving section, to a second position before a first position in which the cartridge body is in a mounted state in the cartridge receiving section;
• and
• moving the electronic component mounting section from the initial position in a second direction different from the first direction to couple the electronic component to electrical coupling portions provided on the printer side, by linearly inserting the cartridge body from the second position to the first position along the first direction.
