Abstract: An image forming apparatus includes at least one paper supply portion including a roll paper accommodating portion adapted to accommodate a paper roll constituted by winding long paper around a shaft, a roll paper holding portion on which the paper roll is temporarily put, a paper feeding portion adapted to deliver paper from the paper roll accommodated on the roll paper accommodating portion, a horizontal rotating-shaft adapted to support the paper supply portion in a body of the image forming apparatus, the paper supply portion drawn outwardly from the body of the image forming apparatus by being rotated when change of the paper roll is performed, wherein the change of the paper roll can be performed by rotating the paper supply portion to thereby draw out the paper supply portion.

Abstract: An apparatus for manufacturing a fibrous fish or shellfish neriseihin product comprised mainly of a bundle of fibrous filaments, each of which includes protein or the like being linearly aligned and a thin surface layer covering over the bundle of the filaments. The apparatus includes a twin screw extruder including two screws rotated in the same direction for kneading, pressurizing and thermally fusing a fish and shellfish material as it is forcibly fed by the screws and for extruding the thermally fused material from an outlet of the extruder.

Abstract: An original plate scanning device for a microfilm copying machine has a guide stand and bearings for supporting a straight shaft member which extends parallel with said guide shaft and is movable linearly relative to the bearing. A semi-solid state lubricant which has an unworked penetration between 200 and 230 is disposed in the bearing for providing a braking force to the moving, straight shaft member.

Abstract: A microfilm copier includes a holding device for the aperature card or the like which is rotatable through a 90.degree. angle so that copying can be effected in either the lengthwise or widthwise direction of the sheet roll comprising the copying medium. The copied images may be of differing magnification in order to minimize the creation of blank, unused portions in the sheet.

Abstract: In a copying machine having an optical system for directing an image from a microfilm onto a photosensitive drum either of two fixed focus projecting lenses may be moved into alignment with the microfilm. Each projecting lens is provided with an adjustable drive system for moving the projecting lens along the optical axis thereof to vary the magnification. A plurality of mirrors are provided for reflecting the image received from said projecting lens onto the photosensitive drum. Two of the mirrors are supported at right angles to each other on a support member for reflecting an incident beam of light on one of the mirrors in a direction opposite and parallel to the incident light beam. A drive system is provided for moving the support member parallel to the incident light beam for varying the length of the optical path.

Abstract: A lens focus controlling device for an optical system includes a first cylindrical cam having a cam face formed on at least one end thereof, a second cylindrical cam having a cam face on one end thereof slidably disposed in contact with said first cam face over a predetermined range, a lens group secured to said second cylindrical cam, a stop member operatively engageable with said lens group to prevent rotation while allowing reciprocation of said lens group along the optical axis thereof and a drive system for rotating said first cylindrical cam relative to said second cylindrical cam.

Abstract: A fibrous food product is produced by the steps of: adding salt to fish and/or animal meat; kneading the resulting mixture to prepare a paste; and extruding the paste into an aqueous solution of a protein modifier through a nozzle having fine orifices to produce filaments. By varying the conditions of this process, the food filaments of various textures or mouth feeling can be produced. Further, the filaments can be aggregated in a variety of ways to further increase the variety of textures or mouth feeling and to produce various muscle-like fibrous food products.

Abstract: A magnification enlargement type copying machine in which the image of a picture on a film is projected onto a screen or a photo-sensitive drum by an image enlarging lens to be observed and copied. The size of a picture on a film to be copied and a size of a copying sheet on which an enlarged image of said picture are inputted to the system. An enlargement magnification is then observed and following correct placement on the proposed sheet, the film is moved from the observation position to a scanning start position according to the size of the picture on the film. The film is then scanned at a speed corresponding to a set magnification thereby to form the image of the picture on a photosensitive drum. An arithmetic control unit is used for calculating a distance between an observation position and a scanning start position from a size of a picture on the film and calculates the film scanning speed from a set magnification.

Abstract: A placing stand for use with a microfilm copying device or the like is driven by means of a step motor connected to the stand by wires or the like. A flywheel is coupled to the shaft of the step motor via a one way clutch so as to damp vibrations of the step motor, while allowing the stand to be quickly returned; the flywheel is not a load on the motor in the return direction.
