Patent ID: 8262214

Claim:
An ink jet recording apparatus comprising: a guide rail extending in a first direction; an ink head that slidably engages with the guide rail and discharges an ultraviolet light curable ink toward a recording medium; an ultraviolet light irradiation device that is attached to the ink head to move together with the ink head and that irradiates ultraviolet light to the ultraviolet light curable ink discharged from the ink head onto the recording medium; a second head that slidably engages with the guide rail; a carriage that moves along the guide rail; a first connection mechanism that detachably connects the carriage with the ink head; a second connection mechanism that detachably connects the carriage with the second head; and an irradiation prohibition mechanism that prohibits the irradiation by the ultraviolet light irradiation device based on a predetermined condition relating to a connection state between the carriage and the ink head caused by the first connection mechanism, wherein the irradiation prohibition mechanism detects whether the first connection mechanism connects the carriage with the ink head, and prohibits the irradiation by the ultraviolet light emitting device upon detecting that the first connection mechanism does not connect the carriage with the ink head.
