    摘要: A color image scanner and color image scanning method that generates three different colors independently using multiple LEDs and controls the exposure time of a charge coupled device (CCD) and the light emitting time of the LEDs in order to maintain suitable balance and levels for the colors which are generated. A primary timer sets the operation time of the CCD and a secondary timer sets the ON time for each LED. In addition, an LED drive circuit driving the LEDs has two constant current circuits to more evenly read the images of the document to be scanned.

    摘要: An image reading apparatus for reading an image on film which uses a shading correction coefficient computation unit for obtaining a shading correction coefficient in order to correct irregularities in image signals of a photoelectric conversion unit, and a quantity of light ratio measurement unit for obtaining the ratio of the quantity of light of each emission color in order to equalize the quantity of light emitted by a light emission unit. The shading correction coefficient and the quantity of light ratio are obtained immediately before reading of a first original medium, and additional original mediums can then be read using the correction coefficients obtained for the first original. Alternately, the shading correction coefficient and the quantity of light ratio can be obtained immediately before reading each original medium.

    摘要: To provide an illumination device in which there is no variation in light intensity distribution of the illumination device, and in which illumination spots, particularly light intensity spots, are not prone to occur in a read image in an image reading device, by maintaining a constant gap between a light source and an end face of a light guide. The illumination device includes: a light guide having an end face for taking in light, a diffuse reflecting surface for diffusely reflecting the light taken in from the end face, and a light exit surface for emitting the light that is diffusely reflected at the diffuse reflecting surface towards an irradiation surface. The illumination device further include a reflector having a diffuse reflecting surface that reflects light from the light source toward the one end face of the light guide. The light guide has, at the one end, a flange portion that abuts the reflector, the light source is mounted to a circuit board, and the reflector is held between the flange portion of the light guide and circuit board so as to maintain a predetermined gap between the light source and light guide.

    摘要: A laminated sheet is produced by forming an adhesion layer permeable to a liquid component and contactable with a skin on at least one side of a liquid-retention layer comprising a nonwoven structural member and having an ability to absorb the liquid component. The adhesion layer comprises a nonwoven structural member comprising a fiber having a number-average fiber diameter of not more than 10 μm, and the thickness ratio of the adhesion layer relative to the liquid-retention layer is 1/4 to 1/100 as a ratio of the adhesion layer/the liquid-retention layer. The fiber of the nonwoven structural member of the adhesion layer may have a standard deviation of fiber diameter of not more than 5. The nonwoven structural member of the liquid-retention layer may comprise a fiber having a fiber diameter larger than that of the fiber of the adhesion layer. The laminated sheet has a liquid retentivity and a liquid releasability in a well-balanced manner, and has an excellent adhesion and an excellent fit to the skin in the state where the sheet is impregnated with a liquid component.

    摘要: To realize a mechanism that can support an article at a desired position in such a way as to be able to move the article, with a thin, simple configuration.A load support mechanism 1 includes a fixed support section 2, which includes a fixed cam 8; a movable support section 3, which receives a load and can move vertically; a horizontal cam groove 13, which is provided in the movable support section; a cam follower member 15, which can move horizontally along the cam groove; a first spring 4, which is mounted between the fixed support section and the movable support section to support a load; and a second spring 18, which pushes the cam follower member horizontally and presses the cam follower member against a fixed cam surface 9 of the fixed cam. A reaction force of the fixed cam against the cam follower contains a vertical component depending on a height position of the movable support section, and the vertical component assists or reduces the spring's force to push up the load. A cam shape of the fixed cam surface is provided in such a way that the load acting around the cam follower, the spring forces of the first and second springs, and the reaction force applied from the fixed cam are balanced against each other.
