摘要:
An improved screen drum type electrographic apparatus which can obtain a picture image having a correct aspect ratio is disclosed. The apparatus comprises a cylindrical lens arranged in an optical passage including an optical system for scanning a manuscript such as printed matter disposed on a table. The cylindrical lens has such a radius of curvature that an image magnification in the scanning direction only is defined by 1/K (K>1) and a length which is sufficient to optically cover the scanning width of a screen drum or the manuscript. The apparatus is so constructed that the ratio of the peripheral speed of the screen drum to the moving speed of the manuscript table or the optical system for scanning manuscript is defined by 1/K.

[Purpose] To provide a surface illumination fixture using a point light source having strong directivity.[Constitution] In the surface illumination fixture 3 including a surface illumination light-source device 6 converting light from a plurality of point light sources 36 having strong directivity into surface illumination and an illumination fixture main body 41, the surface illumination light-source device 6 includes a casing 30 having a flat plate part 35 being used to attach the surface illumination light-source device to the illumination fixture main body, lateral plate parts standing from the flat plate part, and an opening on a surface opposite to the flat plate part, and includes a light-guide reflection plate covering the opening. The flat plate part 35, the lateral plate parts 32 and 33, and the light-guide reflection plate 40 are formed by members having a high light reflectance and a low light transmittance. The light-guide reflection plate 40 is formed to have a lower light reflectance and a higher light transmittance as the distance from the corresponding point light source increases. The illumination fixture main body 41 having attaching means for attachment to a ceiling or a wall.

A light source device is provided with an LED having strong directivity, a reflective hood which has an interior reflecting surface for reflecting the illumination light from the light source, and a pair of first and second polarizing reflective plates for polarizing the illumination light from the LED in a specific direction. The first and second polarizing reflective plates have a specific length and width, and a back surface formed from a high reflectance plate. The light source is secured to the reflective hood. A specific interval is provided between the first and second polarizing reflective plates and the reflecting surface of the reflective hood, and a specific interval is provided between the two plates with the optical axis passing through the 0° direction angle of the light source in between.

An illumination device includes: a point light source; a substrate; a hollow frame having an engaging bent section at one of its edges; and a bottom surface reflection section, a side surface reflection section, and a light conducting reflection plate that are disposed inside the frame. The light conducting reflection plate is held between the bent section and the side surface reflection section that is held by the other edge of the frame and the bottom surface reflection section fixed to the substrate. The surface of the bottom surface reflection section facing the light conducting reflection plate, the inner surface of the side surface reflection section, and the surface of the light conducting reflection plate facing the bottom surface reflection section have high light reflectivity and low light transmissivity.

In a surface lighting unit comprising a footprint portion, a sidewall portion, and an optical reflector with an opening spaced apart by a predetermined distance from the footprint portion. The opening substantially satisfies a relation A=bx2+c, assuming A is the open area ratio, i.e. the ratio of the opening area in a preset predetermined region to the area of the preset predetermined region, b and c are constants, and x is the distance from the center of the optical reflector. The opening has a circular non-through hole concentric to the center of the optical reflector, a concentric arcuate hole on the outside thereof, and a plurality of round holes farther on the outside thereof.
