PROBLEM TO BE SOLVED: To provide a recorder for detecting the non-delivery of nozzles by irradiating a receiving optics with a light required even if the nozzle train is difficult to be located on a light flux due to a delivery port and delivered ink droplets being small when intending to detect the non-delivery optically using the light flux connecting the receiving/emitting optics. SOLUTION: The non-delivery is detected by providing a recording section with an optical guide coupled with the nozzle train or the optical guide together with an aperture.
