Claim:
A cartridge adapted to be removably attached to a cartridge mounting structure comprising a printing material supply tube fixed to a device front wall member and having a central axis extended in a predetermined direction, a rod provided on the device front wall member and having an axis parallel to the central axis and movable in a direction of the axis, and a sensor configured to detect displacement of the rod, wherein three mutually orthogonal special axes are X axis, Y axis and Z axis, directions along the X axis, the Y axis and the Z axis are respectively X-axis direction, Y-axis direction and Z-axis direction, a negative Y-axis direction represents a direction in which the cartridge is inserted into the cartridge mounting structure, and a positive Y-axis direction represents a direction in which the cartridge is removed from the cartridge mounting structure, the cartridge comprising: a casing including: first two faces opposed to each other in the Y-axis direction, one of the first two faces being a front face having an substantially rectangular shape located on the negative Y-axis side and having a length in the Z-axis direction greater than a length in the X-axis direction, and an another one of the first two faces being a rear face located on the positive Y-axis side; second two faces opposed to each other in the Z-axis direction and intersecting the front face and the rear face, one of the second two faces being a first side face located on a positive Z-axis side, and an another one of the second two faces being a second side face located on a negative Z-axis side; and third two faces opposed to each other in the X-axis direction and intersecting the front face, the rear face, the first side face and the second side face, one of the third two faces being a third side face located on a positive X-axis side, and an another one of the third two faces being a fourth side face located on a negative X-axis side; a printing material containing portion provided inside the casing; a first insertion hole formed in the front face and adapted to receive the rod, the first insertion hole located on the front face at a middle position between the first side face and the second side face; a second insertion hole formed in the front face and adapted to receive the printing material supply tube; and a printing material flow path provided inside the casing and having first and second ends, the first end being a printing material supply port adapted to receive the printing material supply tube therein and located at the second insertion hole, and the second end connected with the printing material containing portion.
