Abstract: PROBLEM TO BE SOLVED: To suppress the idling torque of a torque limiter to a low degree so as to improve the durability of a retard roller. SOLUTION: A sheet material feeding device for separatively feeding sheet material sheet by sheet in order has a feed roller 1 for conveying the sheet material, and a retard roller 2 rotated in a reverse direction to the rotating direction of the feed roller 1 so as to separate one sheet material. A driving force transmission device 40 for transmitting driving force to the retard roller 2 includes a torque limiter 46 with its output side connected to the retard roller 2. The torque limiter 46 is so constituted that idling torque is smaller in the case of the output side (output part) being rotated than the case of the output side being stopped.

Abstract: PURPOSE: To measure an output of laser beam without lowering rigidity of a case by leading the laser beam to a sensor on a circuit board with a mirror as an optical path revision means and measuring the output of the laser beam with the sensor. CONSTITUTION: When the laser output is adjusted, a lever 49 is operated, and the mirror 46 is inserted onto an optical path 01. Then, when a laser beam source 35 is emitted, the laser beam from the laser beam source 35 is reflected by the mirror 46 after transmitting through a lens barrel 36, a diaphragm plate 37 to be made incident on the sensor 51 through a hole 50. The output of the sensor 51 is outputted to a tester, and the output of the laser beam is measured. A detector adjusts the output of the laser beam so as to become a prescribed value while viewing the measurement value. After adjustment, the detector releases a service mode, and operates the lever 49 to retreat the mirror 46 from the optical path 01. Thus, the necessity that a large hole for inserting a measuring sensor into a laser beam path from the outside of the device is provided when the laser output is adjusted is eliminated.

Abstract: PURPOSE:To eliminate such a trouble that the central part of a picture becomes darker by providing a correcting means which corrects the luminance distribution of an object image made incident to an image pickup means between the image pickup means which is held within a prescribed crose range against an object placing section and takes the image of the object and lighting means which illuminates the object placed on the object placing section. CONSTITUTION:This image pick up device is provided with an object placing section on which an object is placed, image pickup means 11 which is held within the prescribed crose range against the object placing section and takes the image of an object, lighting means 42 which illuminates the object placed on the object placing section, and correcting means 35 which corrects the luminance distribution of an object image made incident to the means 11. Accordingly, a light source can produce such luminance distribution that can compensate a decline in the peripheral light quantity at the image pickup time. Therefore, such a trouble that the central part becomes darker at the time of negative-positive inversion can be eliminated.

Abstract: PURPOSE:To easily and accurately perform close-up of a camera film by providing a placing base, on which an object is to be placed, between a light source part and a camera setting part and illuminating the placed object by the light source to photograph it by a camera. CONSTITUTION:This device essentially consists of a camera setting part 22, to which an electronic still camera 1 is set, and a light source part 23, and a camera film 24 is held by a film holding member 25 and is inserted between them in this state. That is, a film placing base 36 is provided under the camera setting part 22 and a prescribed space apart from the camera setting part 22, and the film 24 held by the film holding member 25 is inserted to the upper face of the placing base 36 in the longitudinal or transverse direction. The light source part 23 placed under the camera setting part 22 is provided with a light source 40 facing an aperture part 37 of the placing base 36. Thus, close-up of the camera film 24 is easily and accurately performed.

Abstract: PURPOSE:To provide the degree of freedom in the arrangement of a device in a camera so that the constitution of the camera is facilitated by forming a transparent protecting plate as wedge-shaped whose photographing lens side is thick. CONSTITUTION:An electric still video camera 1 is constituted of a photographing system provided with a photographing lens 2, an optical lowpass filter 3 and a photographing element CCD 4. In addition, a real image type of a second image forming method finder is constituted of an object lens 5, a primary focal plane 6, a secondary image forming lens 7, a secondary focal plane 8, and an ocular lens 9. Here, the parallax of a finder system is comparatively inconspicuous, whereas, the parallax of a stroboscopic light emitting system is large so that correction is needed. In order to perform the correction, the protecting plate 10a is formed as wedge-shape having the angle of thetap, and a stroboscopic light emitting tube 11a and a reflector 12a can be arranged perpendicular to a photographing optical axis. Therefore, the degree of freedom is provided on the arrangement of the stroboscopic light emitting system, so that the constitution of the camera is facilitated.

Abstract: PURPOSE:To obtain a legible display in a photographing range with a variety of focal length without parallax and an unnecessary frame display by varying the position of a finder visual field frame in a finder according to information from a means calculating the parallax of the finder based on information on the distance of an object. CONSTITUTION:A range finding circuit 12 measures a distance up to an object, and simultaneously a focal length detecting circuit 11 detects the focal length of a photographing lens. Then information from these circuits is transmitted to a parallax calculating circuit 13. When the circuit 13 obtains parallax at this time from information on the distance of an object and information on focal length, a pulse corresponding to the calculated parallax is transmitted to a pulse motor M through a motor driver circuit 14. When the pulse motor M drives to rotate a gear 4, a frame member 1 moves. At such a time, the moving amount of a visual field frame 1a (opening part) 1a becomes smaller if a focal point is shorter, whereas if it is longer, the 1a becomes greater. Thus, a range when photographing with a variety of focal length can be displayed visibly without parallax and an unnecessary frame display to inform a photographer.
