Inkjet recording device and inkjet head head-module replacing method

An inkjet recording device comprising:

• an inkjet head including a base frame, a plurality of support devices that are provided on the base frame at regular intervals, a plurality of head modules that are joined in a line by being mounted on the base frame through the support devices, a plurality of position adjusting devices configured to individually adjust the positions of the head modules mounted on the base frame, and a plurality of position detecting devices configured to individually detect the positions of the head modules, which are mounted on the base frame, relative to support reference points that are set at the respective support devices and serve as references;
• a first storage device which is provided on the base frame and in which information about the positions of the respective support reference points is stored;
• second storage devices which are provided in the respective head modules and in which information about the positions of nozzles of the head modules is stored;
• a third storage device in which information about the positions of the nozzles of the respective head modules mounted on the base frame is stored;
• and
• a position-correction-information generating device configured to generate information about the correction of a position, which is required to mount the replaced head module at a normal position, based on the information stored in the first storage device, the information stored in the second storage devices, and the information stored in the third storage device when the head module is replaced.
