摘要： PURPOSE:To eliminate distortion in a subscanning direction by running a scanning plural times by the rotary movement of one mirror surface and holding the inclination of the subscanning direction of a scanning beam to a scanned surface nearly at the right angles and moving an optical scanning system in the subscanning direction. CONSTITUTION:When the light transmission part of a beam splitter 4 rotates until luminous flux 2 strikes it while the light beam pass through a point 41 to make an ineffective scan, the luminous flux 2 is transmitted through the light transmission part of the beam splitter and reflected by a fixed reflecting mirror 7 to strike a surface 8 of a rotary polygon mirror which still rotates and reflected the luminous flux previously at a different angle again; and the luminous flux is reflected there to form an image on a detection plate 30 through an ftheta lens 9, making the 2nd photoscan. Then, when light forms an image at a point 40 and the 1st photoscan is made toward the right side in a figure, a moving substrate 37 moves continuously at an equal speed in the subscanning direction shown by an arrow by rotating screw 44.

摘要： PURPOSE:To perform plural times of scanning with one turning movement of a specular surface by making the light beam entering a rotary polyhedral mirror incident time dividedly to different beam paths. CONSTITUTION:When laser light is reflected by a beam splitter 4 and advances in a direction 2a, and if the angle between the luminous flux 2a thereof and the face 8 of a rotary polyhedral mirror 6 is 45 deg., the light is reflected by the face 8, advances in a direction 3b and forms its image on an imaging plane O. If the face 8 of the mirror 6 is located at 11 deg. before the same, the image is formed on an imaging plane 12. When the angle between the light 2a and the face 8 advances further from 45 deg. to 56 deg., the image is formed on an imaging plane 13. When the mirror 6 is rotated non-effectively by 8 deg. rotating angle, the light 2b heading through the mirror 7 toward the mirror 6 falls onto the face 8 of the rotary mirror and is reflected in the direction of light 3a, drawing the same main scanning line as the light 2a. The efficiency is higher than in the case in which the light is made incident to the polyhedral mirror from one direction only.

摘要： PURPOSE:To deal with the alteration of information on a latent image in the lapse of time and to compensate it and obtain a desired signal, by generating a reference signal corresponding to the alteration of the information recorded on a detector in the lapse of time. CONSTITUTION:A transparent electrode 801, photoconductor layer 802, insulator layer 803, boundary surface 804 between both layers, and layered electrode 805 are formed in one body to constitute the detector 800. An electrostatic latent image corresponding to the pattern of a negative film 815 is formed on the detector 800. A shielding plate 820 is arranged closely to the detector 800 outside of the range where the electrostatic latent image is formed to cut off incident exposure light 811, placing this area (reference area) of the detector 800 invariably in a dark state. Therefore, charges 821-823 are charged in the shielded area of the detector 800 all the time. Then, the shielding plate 820 is removed and an optical scanner is set in front of the detector 800 to makes a two-dimensional scan by laser spot light, obtaining reference signals 920-924 as shown in a figure. Those reference signals are used to partial waveforms 902-916, obtaining desired signals.

While the X-ray not converted into the light by the phosphor board (A) but reached to the phosphor material layer 3 is converted to the visible light beam near the point Q1 and scattered and a portion of it is reflected at the point (R1) on the surface of the phosphor board (A') to be emitted to the outside. The portion of the light emitted at the point (P) and reached to the point (Q2) on the fluorescent material layer 3 will also be scattered and reflected by the phosphor material layer 3 and a portion of it is reflected at the point (R2) on the surface (A') and emitted to the outside. Consequently the transmitted X-ray and a portion of the converted light not utilized conventionally can be utilized effectively resulting in the improvement of the brightness of the phosphor board (A).

摘要： PURPOSE:To improve electric stability, by providing a detector of multilayered structure with moistureproofing and dustproofing treatment. CONSTITUTION:The multilayered structure 600 uses a resin plate which is a rigid substrate and made of acrylic resin, etc., having superior electric insulation.

For this purpose, end faces of respective layers are sealed with a sealing material 609 of epoxy resin, etc., having high insulating resistance and strength. Further, the surface of a transparent electrode 606 is coated with transparent resin 610 to form a protecting layer, cleaning dust, dirt, etc., easily. Pins 612 and 612' are provided on the left and right sides of the substrate 601 to position the detector itself accurately. An electrode 603 is extended to the rear surface of the acrylic plate 601, so a contact 607 is provided by applying gold by vacuum deposition. An electrode 606 is also provided with a contact 608 with the substrate 601 between as well as the contact 607.

摘要： PURPOSE:To enable the reduction in the size of a detection plate, by forming once the image of an object to be detected by image exposure, forming the image thereof on the detection plate with an imaging means, scanning the same with a beam and detecting the image time-serially. CONSTITUTION:The X-ray 18 transmitted through an object 16 to be examined by image exposure is made incident to a fluorescent plate 22 behind a front plate 19, and the optical image corresponding to the X-ray transmitted section of the bject 16 is formed thereon. The image thereof is formed on a detection plate 7a having sensitivity to visible light by an imaging lens 23. If the projecting magnification to the plate 7a is made smaller than 1, the plate 7a can be made smaller; therefore, the production of the detection plate for which uniformity in flatness, etc. is required is made easiter and further the area of the detection plate is made smaller and the overall scanning time is reduced. If the projecting magnification on the plate 7a is made larger than 1, the image expanded from a part of the object is formed on the plate 7a.
