Liquid cartridge having movable member and contact member, and system using the same

A liquid cartridge comprising:

• a cartridge body accommodating a reservoir configured to store liquid therein, the reservoir being deformable;
• a liquid-supply part provided on the cartridge body and configured to allow the liquid stored in the reservoir to flow out therefrom;
• a movable member movably supported by the cartridge body and including a detected part subject to external detection, the detected part being movable from a detected position to a non-detected position rearward of the detected position;
• and
• a contact member provided at a surface of the reservoir and configured to contact the movable member, the contact member in contact with the movable member restricting the detected part at the detected position from moving to the non-detected position, the detected part at the detected position being positioned higher and exposed upward relative to the cartridge body.

A system comprising:

• a liquid cartridge comprising:
• a cartridge body accommodating a reservoir configured to store liquid therein, the reservoir being deformable in accordance with outflow of the liquid from the reservoir;
• a liquid-supply part provided on the cartridge body and configured to allow the liquid stored in the reservoir to flow out therefrom;
• a movable member movably supported by the cartridge body and including a detected part subject to external detection, the detected part being movable from a first position, to a second position rearward of the first position, and to a third position rearward of the second position, the detected part at the first position and at the second position being positioned higher relative to the cartridge body;
• an urging member provided on the movable member and resiliently deformable;
• and
• a contact member provided at a surface of the reservoir and configured to contact the movable member;
• and
• a cartridge-receiving section, the liquid cartridge being configured to be inserted into the cartridge-receiving section in a frontward direction, the liquid cartridge being configured to be removed from the cartridge-receiving section in a rearward direction, the cartridge-receiving section comprising:
• a first light-emitting part;
• a second light-emitting part disposed rearward of the first light-emitting part;
• and
• an abutting part configured to abut on the urging member, the urging member being resiliently deformed upon contact against the abutting part to generate an urging force to urge the detected part toward the third position, the detected part at the first position moving to the second position upon receipt of the urging force of the urging member, the contact member in contact with the movable member restricting the detected part at the second position from moving to the third position against the urging force of the urging member, the contact member being configured to move in accordance with deformation of the reservoir to release the contact between the movable member and the contact member and to move the detected part at the second position to the third position due to the urging force of the urging member, the detected part at the first position being configured to block light emitted from the first light-emitting part during insertion of the liquid cartridge into the cartridge-receiving section, the detected part at the second position being configured to block light emitted from the second light-emitting part upon completion of mounting of the liquid cartridge in the cartridge-receiving section.
