An inkjet recording device, capable of reliably detecting obstacles such as wrinkles or foreign particles on a recording medium, is provided with a clearance sensor mechanism for detecting foreign particles and wrinkles on the recording medium. In such an inkjet recording device, printing is performed by scanning with the inkjet head while a platen on which the recording medium is mounted is fed. When a plate-like member provided between the default position in which the platen is on standby and the printing performing position to be scanned by the inkjet head contacts foreign particles or wrinkles of the recording medium mounted on the platen, the concealing member, together with the plate-like member, rotates about the axis line direction of an axis member. When a sensor detects the rotation of the concealing member, the platen is fed in the reverse direction. Further, when the inkjet head starts printing, a solenoid presses a receiving member and rotates the plate-like member.
