摘要： Laser light emitted from a laser light source is converted into light having a dot pattern by a projection optical system for projection onto a target area. The projection optical system is configured such that the density of dots in a peripheral portion of the dot pattern is smaller than that in a center portion of the dot pattern in the target area. A dot pattern captured by irradiating a dot pattern onto a reference plane is divided into segment areas. A distance to each segment area is acquired by matching between dots in each segment area, and a dot pattern acquired by capturing an image of the target area at the time of distance measurement. The segment areas are set such that a segment area in the peripheral portion of the dot pattern is larger than a segment area in the center portion of the dot pattern.

摘要： An information acquiring device includes a laser light source which emits light in a predetermined wavelength region; a projection lens which projects the light from the laser light source toward a targeted area; an image sensor which receives reflected light reflected from the targeted area to output a signal; and an imaging lens which guides the reflected light to the image sensor; a filter which transmits the light from the laser light source; and an actuator which inclines the filter. A filter controlling circuit inclines the filter in such a direction as to approximate a transmissive wavelength region of the filter to the wavelength region of the light from the laser light source.

摘要： A split seal paper sheet in which the width of split seals composing the split seal paper sheet in the direction of conveyance of the paper sheet is smaller than the print width of a serial head is used. One or more of the split seals is/are positioned in one scanning region of the serial head, to print an image on the split seals. Line feed for printing on one or more split seals in the subsequent line is performed in such a manner that the line feed width is the same as the print width of the serial head. Consequently, the entire image is formed on one split seal without conveying the paper sheet (performing line feed). Even if a pitch between lines becomes non-uniform in conveyance of the paper sheet, the image on the split seal is not degraded.

摘要： A surface lighting device includes a stick type light guide body. The stick type light guide body receives a light emitted from a light emitting surface of an LED fixed on a substrate from a side surface which faces to the LED and emits the received light from a side surface which faces to a light guide plate. The emitted light is incident from a side surface of the light guide plate and is emitted from an upper surface of the light guide plate. Then, the substrate is formed with a through hole, and the stick light guide is formed with a protrude portion on the lower surface thereof. By fitting the protrude portion into the through hole, the LED and the stick type light guide body are relatively positioned such that the light emitting surface of the LED and the side surface of the stick light guide are brought into close contact with each other.

摘要： This invention was made to reduce cost and the number of assembly processes and improve productivity by making viewing angle characteristics of light emitted from a light emitting surface even irrespective of a point in a bar-shaped light guide. A bar-shaped light guide of this invention comprises a light incident surface for receiving light emitted from a point light source, a light emitting surface, which is orthogonal to the light incident surface, for emitting light received on the light incident surface in a form of beam light, and a pattern surface made up of a side of the light incident surface and a side of the light emitting surface and having a plurality of grooves formed thereon. The plurality of grooves are regularly arranged on the pattern surface. An angle formed by the groove 106 and the side of the light emitting surface on a side of the point light source is 35-55°.
