摘要： PURPOSE:To prevent the occurrence of black/white streaks on a copied picture, by constituting the titled device in such a way that the lengthwise direction of the clearance section between transparent electrode groups installed in a matrix form does not coincide with the scanning direction but crosses the scanning direction at a prescribed angle. CONSTITUTION:When a transparent slit pattern SP indicated by the non-hatched parts is formed as shown in the obliquely viewed diagram, only one electrode is isolated out of transparent electrodes 30-1-30-10 consisting a transparent electrode group 30 and the isolated electrode is moved from the 30-1 to 30-10. At the same time, correspondingly to the isolated electrode, transparent electrodes 31-1-31-11 consisting a transparent electrode group 31 corresponding to a part forming a slit pattern SP are synchronously isolated. When, for instance, the transparent electrode 30-5 is isolated, the transparent electrodes 31-6, 31-7, and 31-8 are simultaneously isolated. When this operation is made, a part of the slit pattern SP is formed. Therefore, by successively performing this operation to the transparent electrodes 30-1-30-10 and repeating the successive operations to the electrodes, a normal slit pattern SP is formed.

摘要： PURPOSE:To obtain copy image of high quality by using two cylindrical Fresnel lenses which have an axis perpendicular to a scanning direction and an axis crossing the scanning direction respectively, and arranging those lenses one over another and alloying them to reciprocate at a specific speed. CONSTITUTION:The Fresnel lenses 10 and 11 are arranged in or near the image formation surface of a projection lens 7; enlarged projection light from the projection lens is converged and the resulting converged light is allowed to strike an image forming lens arranged in a copying part 2. The upper Fresnel lens 10 consists of the cylindrical Fresnel lens having the axis perpendicular to the scanning direction (a) and has a relatively large shape to allow the light of the entire picture to be copied at the same time; the lower Fresnel lens 11 consists of the cylindrical Fresnel lens having the axis crossing the scanning direction (a) and is made in a long and thin slit shape to allow the incidence of only part of the entire-picture light. The concatenation surface 1b of the upper Fresnel lens 10 is formed into a diffusing surface, which is rugged finely in conformity to a concatenation surface 1b.

摘要： PURPOSE:To obtain copy images of high quality of arranging plural Fresnel lenses one over another in or near the plane of an air image, and using a cylindrical Fresnel lens having an axis crossing a scanning direction as one of said Fresnel lenses and allowing it to move. CONSTITUTION:Fresnel lenses 10 and 11 are arranged in or near the image formation surface of a projection lens 7 and enlarged projection light from the projection lens 7 is converged to enter an image forming lens 7 arranged in a copying part 2. The upper Fresnel lens 10 consists of the cylindrical Fresnel lens having the axis perpendicular to the scanning direction (a) and is large enough to allow entire-picture light to be copied to strike the lens at the same time; the lower Fresnel lens 11 consists of the cylindrical Fresnel lens having the axis crossing the scanning direction (a) and is formed in a long and thin slit shape to allow the incidence of only part of the picture light. The Fresnel lenses 10 and 11 have the lens surfaces facing each other to reduce the loss of the quantity of transmitted light.

摘要： PURPOSE:To prevent a developer from ununiformly swelling, and to make liquid thickness constant, by slanting the corona discharging wire of an excessive developer removing device in the widthwise direction of a drum, and equalizing the interval size between the drum and discharging wire at at least two positions. CONSTITUTION:The corona discharging wire 4 of an excessive developer removing device is slanted widthwise in three dimensions to a photosensitive drum 1, and the interval between the drum surface and discharging wire 4 is equalized at at least two positions. As a result, an excessive insulating liquid developer is squeezed on one side of the drum 1 and the developer is movable widthwise on the drum surface, so the developer after being squeezed by corona discharge swells uniformly to constant liquid thickness.

摘要： PURPOSE:To obtain a reflection tupe screen for reader printers that can easily detect the density of the image desired to be copied by providing an opaque photoelectric conversion layer on the back of a light transmittable light diffusion layer. CONSTITUTION:A reflection type screen 0 is formed by providing a photoelectric conversion layer 29 and a light transmittable light diffusion layer 30 over the entire surface of a substrate 28. At the time of observation, a microfiche held in a carrier 16 is irradiated with the light from a light source 3, and the transmitted light thereof is reflected by a mirror 8 and is projected to the screen 10, by which the image information is read. On the other hand, if it is desired to copy the image information, the screen 10 is moved to an opening part 18 for observation (broken line position 10'), and copying paper S is set in the position where there had been the screen 10, thereafter the light source 3 is lighted by a prescribed time by the signal from a storage circuit which has held the output of the photoelectric conversion layer 29 of the screen 10, whereby the copying paper S is exposed (however, the value corrected with the output component of the layer 29 by external light is used for the above-mentioned signal).

摘要： PURPOSE:To accomplish reliable location control merely through addition detecting signals to an offering line by impressing the offering signals, which accord to the rise and break of the mark detecting signals of microfilm, upon a computer. CONSTITUTION:Optically detecting signals of the mark b of microfilm F are impressed at one hand upon a differentiation circuit 10 through an AND circuit 6 and an OR circuit 9 and at the other upon the circuit through an inverting circuit 7, an AND circuit 8 and the OR circuit 9. In accordance with the differential outputs of the same polarity of the circuit 10, the inconductions of the circuits 6 and 8 are controlled through a trigger type FF 12. The differential output is impressed as offering signals upon a computer 11. Thus, the computer accomplishes the location, while control words being at a high level, in response to the first differential output, and interrupts the counting operation, while the control words being at a low level, in response to the second differential output. Thus, it is possible to accomplish the reliable location control of the microfilm merely by impressing the detecting signals upon a single offering line.
