The purpose of the present invention is to provide a technique by which satisfactory contact between a cartridge-side terminal group and a device-side terminal group is achieved. A printing device is provided with a front surface, a back surface, a first side surface, a second side surface, a third side surface, a fourth side surface, and a recessed portion. The recessed portion has an opening, first and second sidewalls, and a bottom wall, and the bottom wall has an inclined surface inclined in a direction including a minus Y-axis direction component and a plus X-axis direction component. A cartridge-side terminal group is provided on the inclined surface. A first restriction portion that is brought into contact with a first positioning portion in a plus Z-axis direction and the plus X-axis direction in a mounted state to thereby restrict the movement in the plus Z-axis direction and the plus X-axis direction of a device-side terminal portion is provided in the first sidewall. A second restriction portion that is brought into contact with a second positioning portion in the plus Z-axis direction and a minus X-axis direction in the mounted state to thereby restrict the movement in the plus Z-axis direction and the minus X-axis direction of the device-side terminal portion is provided in the second sidewall. |
