PROBLEM TO BE SOLVED: To provide a liquid cartridge which can judge whether or not a liquid droplet ejection head of the used liquid cartridge can be reused on the basis of information on a use hysteresis of the liquid droplet ejection head, can manage inventory on the basis of whether or not the reuse is possible, and can further obtain reduction of a price through user's returning of a used ink cartridge, and to provide a liquid droplet ejecting apparatus, a liquid cartridge reader, a liquid cartridge managing system and a management method. SOLUTION: The liquid cartridge 3 is equipped with the liquid droplet ejection head 23 and a storage part 21. The liquid droplet ejecting apparatus 1 writes use hysteresis data of the number of ejection abnormality detection times and an ejection abnormal state into the storage part 21. The liquid cartridge reader 40 reads the use hysteresis data from the storage part 21 of the liquid cartridge 3, judges if it can be reproduced, and generates a resale price. A managing computer 60 connects a plurality of the liquid cartridge readers 40 via a network 61, collects hysteresis data and carries out production control. COPYRIGHT: (C)2006,JPO&NCIPI |
