  • Patent number: 7815278
    Abstract: A detection unit to optically detect a discharge condition of a droplet is disclosed. The detection unit includes a light emitting element and a light receiving element disposed on opposite sides of an area through which a droplet discharged from a droplet-discharger passes. A diaphragm plate having an aperture and another diaphragm plate having at least two apertures arranged at a pitch in a discharge direction are respectively disposed near front surfaces of the two elements. When light emitted from the light emitting element passes through the apertures, two light beams are received by the light receiving element. When the droplet is discharged and passes in front of the apertures, the two light beams are blocked sequentially by the ink droplet, which causes the quantity of light received by the light receiving element to change, thereby inducing a change in an output from the light receiving element. Based on the change in the output, a discharge-condition of the droplet is determined.

  • Patent number: 7621616
    Abstract: A recording head includes an ink-discharging surface and nozzles. The ink-discharging surface is provided with ink-discharging ports of the nozzles. A light-emitting element and a light-receiving element are disposed opposite each other close to the ink-discharging surface. The light-receiving element outputs a detection signal. A reflector is provided on the ink-discharging surface and reflects light emitted from the light-emitting element toward the light-receiving element. One of the nozzles is driven and whether the nozzle discharges an ink drop is checked on the basis of change in the detection signal due to interception of the reflected light by the ink drop. If the nozzle discharges an ink drop, then whether the nozzle discharges the ink drop in an appropriate direction is checked on the basis of change in the detection signal due to interception of the direct light by the ink drop.
