Patent ID: 7175354

Claim:
An inkjet printing device, comprising: a holding unit that is used to hold a substrate to be subjected to printing operation; a housing; an inkjet head that ejects ink onto the substrate held by the holding unit and reciprocates in a lateral direction of the housing, wherein the holding unit is movable between a first posture which allows the inkjet head to eject the ink onto the substrate held by the holding unit and a second posture in which the substrate is loaded onto the holding unit, the holding unit is movable in an anteroposterior direction of the housing and reciprocates between a substrate set position at which the substrate is loaded onto the holding unit and a print position at which the inkjet head ejects ink onto the substrate, and the holding unit includes: a platen rotatable around an axis extending in parallel with the lateral direction and rotates around the axis so that the platen is movable between the first posture in which the platen faces the inkjet head and the second posture in which the substrate is loaded onto the platen; and a locking mechanism that brings the platen into a locked state at the first posture and the second posture.
