    摘要: A heating roller unit includes a heating roller, a heat source disposed inside the heating roller, and a tubular member at an end of the heating roller. Inside the tubular member, a terminal of the heat source is disposed. The tubular member has an opening via which inside of the tubular member communicates with an outside in a direction intersecting with an axial direction of the heating roller.

    摘要: An apparatus includes: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the source to the subject. When a specular position of the source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the source toward the first specular position and an incident angle from the source toward the second specular position is a reference value or more.

    摘要: A disclosed liquid-jet device includes a liquid-jet head configured to jet liquid droplets; a pattern formation control unit configured to control the liquid-jet head and thereby to form a test pattern composed of separate liquid droplets on a water-repellent part; a detecting unit including a light-emitting element configured to illuminate the test pattern on the water-repellent part and a light-receiving element configured to receive specularly reflected light from the illuminated test pattern and to output a detection signal proportional to the received specularly reflected light; and a landing position adjusting unit configured to adjust landing positions of the liquid droplets based on the detection signal from the light-receiving element.
