Abstract
A cartridge includes a concave portion. The concave portion has an opening, first and second side walls, and a bottom wall, and the bottom wall has a tilted surface tilted. The tilted surface is provided with a cartridge side terminal group. The first side wall is provided with a first restriction portion which restricts movements in a +Z axis direction and a +X axis direction of an apparatus side terminal unit, and the second side wall is provided with a second restriction portion which restricts movements in the +Z axis direction and a −X axis direction of an apparatus side terminal unit.
Claims11
A cartridge detachably mountable to a printing apparatus, assuming that three orthogonal spatial directions respectively are an X axis direction, a Y axis direction, and a Z axis direction, positive directions along the X axis direction, the Y axis direction, and the Z axis direction are a +X direction, a +Y direction, and a +Z direction, negative directions along the X axis direction, the Y axis direction, and the Z axis direction are a −X direction, a −Y direction, and a −Z direction, the printing apparatus including an apparatus side terminal unit being movable in the X axis direction and the Z axis direction, the apparatus side terminal unit having an apparatus side terminal group, and a first positioning portion and a second positioning portion provided on both sides of the apparatus side terminal group in the X axis direction, the cartridge is configured to be mounted to the printing apparatus by moving from the +Y axis direction to the −Y axis direction, the cartridge comprising:
- a terminal connection portion configured to be connected to the apparatus side terminal unit when the cartridge is mounted to the printing apparatus, the terminal connection portion including:
- a tilted surface tilted in a direction including the −Y axis direction component and the +Z axis direction component and provided with a cartridge side terminal group which is configured to contact the apparatus side terminal group in a mounted state in which the cartridge is mounted to the printing apparatus;
- a first restriction portion provided on the +X side of the cartridge side terminal group;
- and
- a second restriction portion provided on the +X side of the cartridge side terminal group, wherein:
- the first restriction portion and the second restriction portion configured to receive the first positioning portion and the second positioning portion, respectively, from the −Y axis direction to the +Y axis direction, and restrict the apparatus side terminal unit from moving in the X axis direction and the Z axis direction in the mounted state.
