PROBLEM TO BE SOLVED: To attain miniaturization and cost reduction by a simple structure, and to detect a liquid cartridge state of loading. SOLUTION: A liquid cartridge loading detecting mechanism 15 which detects the liquid cartridge 12 state of loading is provided at an intersection of a plurality of liquid cartridge loading parts 21. The liquid cartridge loading detecting mechanism 15 is equipped with: a switch means 36; and a detecting member 32 which has cam parts 39 each projecting to the liquid cartridge loading part 21. While the liquid cartridges 12 are loaded in all of the liquid cartridge loading parts 21, all of the detecting members 32 operate, whereby the switch means 36 operates and outputs a detection signal.
