Abstract: An external input device is employed, the external input device being configured to operate a robot system including an imaging apparatus capable of changing an imaging point of view and a robot apparatus, the external input device includes a display area, a robot apparatus operation unit configured to operate the robot apparatus, an imaging operation unit configured to operate the imaging apparatus, and an image display unit configured to display an image captured by the imaging apparatus, wherein the robot apparatus operation unit, the imaging operation unit, and the image display unit are displayed on the display area, and wherein the image display unit is disposed between the robot apparatus operation unit and the imaging operation unit.

Abstract: A laser irradiation device in which laser light is adjusted to create a laser beam, including a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that passes the laser beam and reflects visible light; a wavelength-dependent optical screening mechanism that cuts off light of a wavelength region other than visible light from the light that is reflected by the reflection mechanism; image pickup camera configured to capture the visible light reflected with the reflection optical element; and an image adjustment lens unit that adjusts an image in the visible light that is input from the wavelength-dependent optical screening mechanism. The wavelength-dependent optical screening mechanism is provided between the reflection optical element and the image camera.

Abstract: A laser irradiation device comprises a laser oscillator, a laser irradiation head that performs laser processing by directing the laser beam onto the region to be processed; and a transmission mechanism that gets the laser beam through emitted from the laser oscillator to the laser irradiation head. The laser irradiation head comprises: a laser beam adjustment unit that adjusts the laser light to create a laser beam; a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that gets the laser beam through and reflects visible light; a wavelength-dependent optical screening mechanism that cuts off light of a wavelength region other than visible light from the light that is reflected by the reflection mechanism; an image adjustment lens unit that adjusts an image comprising visible light that is input from the wavelength-dependent optical screening mechanism; an image pickup camera that inputs an image; and an image processing mechanism that processes the image.
