PROBLEM TO BE SOLVED: To provide techniques for enabling attachment of a print material cartridge in an appropriately correct state, and enabling reduction in the occurrence of failure due to application of a high voltage to a circuit of the print material cartridge.SOLUTION: A printer includes a cartridge attachment part that includes: a terminal pedestal having a printer-side terminal group disposed on a slope surface and a print material supply pipe. Of the printer-side terminal group, one printer-side ground terminal disposed at the center in a Y direction is protruded more than other plural printer-side terminals. A print material cartridge includes a print material accommodation part and a circuit board 400. The print material accommodation part includes a print material supply port and a board disposal part 180 that is sharply inclined from a plane extended from an opening surface of the print material supply port. One cartridge-side terminal of the circuit board 400 is disposed so as to contact the printer-side ground terminal before the other cartridge-side terminals do when the print material cartridge is attached to the cartridge attachment part. |
