Printing-fluid containing device including printing-fluid cartridge and adaptor

A printing-fluid containing device configured to be detachably attached to the cartridge attachment section, the printing-fluid containing device comprising:

• a casing configured to store printing-fluid therein, the casing defining a chamber configured to store printing-fluid therein, the casing having a front wall and a rear wall opposite the front wall, the front wall being apart from the rear wall in a frontward direction, the chamber being disposed between the front wall and the rear wall;
• a supply portion provided at the front wall of the casing and extending in the frontward direction away from the rear wall such that a front end of the supply portion is further frontward of the front wall of the cartridge body, the supply portion being configured to flow the liquid from the chamber in the frontward direction;
• an engagement portion provided at the casing and configured to be engaged with the cartridge attachment section;
• a liquid detection portion provided at the casing and including a light accessible portion configured to be accessed by light emitted from an outside of the printing-fluid cartridge;
• a top wall configured to be detachably attached to the casing;
• and
• an electrical interface provided at the top wall and electrically connectable to an electric contact provided at the cartridge attachment section,
• the top wall being positioned further upward of the supply portion in an upward direction perpendicular to the frontward direction in an attached state where the top wall is attached to the casing,
• the electrical interface being disposed on the top wall such that the electrical interface is positioned further downward of the light accessible portion in the attached state where the top wall is attached to the casing.

• a supply portion provided at the front wall of the casing and extending in the frontward direction away from the rear wall such that a front end of the supply portion is further frontward of the front wall of the cartridge body, the supply portion being disposed further downward of the upper wall in a downward direction opposite to the upward direction, the supply portion being configured to flow the liquid from the chamber in the frontward direction;
• an engagement portion provided at the casing and configured to be engaged with the cartridge attachment section, the engagement portion including a leaf spring;
• a liquid detection portion provided at the casing and including a light accessible portion configured to be accessed by light emitted from an outside of the printing-fluid cartridge;
• a top wall configured to be detachably attached to the casing, the top wall being disposed on the upper wall of the casing in an attached state where the top wall is attached to the casing;
• an electrical interface provided at the top wall and electrically connectable to an electric contact provided at the cartridge attachment section;
• and
• a light attenuation portion provided at the top wall and configured to attenuate light emitted from an outside of the printing-fluid cartridge,
• the top wall being positioned further upward of the supply portion in the upward direction in an attached state where the top wall is attached to the casing,
• the electrical interface being disposed on the top wall such that the electrical interface is positioned further downward of the light accessible portion in the attached state where the top wall is attached to the casing,
• the light attenuation portion being positioned further upward of the electrical interface, the light attenuation portion being disposed between the liquid detection portion and the electrical interface in the frontward direction in the attached state where the top wall is attached to the casing,
• the top wall having a front end and a rear end opposite to the front end in the frontward direction, the light attenuation portion being disposed at a position closer to the rear end of the top wall than to the front end of the top wall.
