    摘要： Apparatus for controlling pivotal movement of a pivotal member on a water closet includes a casing mounted on the water closet, a rotor rotatably mounted in the casing and viscous material interposed between the rotor and the casing providing relative rotational resistance between the rotor and the casing. A joint member coaxial with the rotor is provided and a spring clutch is operably disposed between the rotor and the joint member and operable to drive the rotor in one direction when the joint member is rotated in one direction while permitting the joint member to rotate in an opposite direction without driving the rotor member in such opposite direction. A shaft is connected to the pivotal member, the shaft being coaxial with the joint member. An interplay is interposed between the shaft and the joint member operable to permit the shaft to rotate a first angular amount in such one direction without driving the joint member and operable such that when the shaft continues to rotate further beyond such angular amount in such one direction, the shaft drives the joint member, whereby the pivot member attached to the shaft is freely rotatable in such one direction such first angular amount and thence further rotatable in such one direction to a closed position while being restrained by the viscous material, the pivot member being rotatable in such opposite direction from such closed position to an open position without being restrained by the viscous material.

    摘要： In a slit exposure type copying machine, a projection device basically includes transmission type element lens systems each including a lens having a great length in the direction of the optic axis thereof as compared with the effective diameter thereof. A part area of an original is projected upon a predetermined part area on an image plane and the light intensity distribution of the projected part area has a predetermined central area controlled by lens aperture eclipse and extending diametrically from at least the optic axis and a marginal area lying outwardly of the central area and weak in light intensity. A plurality of such element lens systems are substantially equidistantly arranged in the lengthwise direction of the slit in a plane perpendicular to the optic axis so that the marginal areas in at least the element lens systems are superposed upon one another. Further, the element lens systems are arranged in a plurality of rows so that each row is positioned just intermediate the adjacent row, whereby even if there is an error in the arrangement interval of the element lens systems, the uniformity, in the slit area, of the exposure amount time-integrated in the original scanning direction is maintained.

    摘要： This specification discloses a compact projection device in which lens systems extending in the direction of the optic axis for projecting a part area of an object upon a predetermined part area on an image plane (hereinafter referred to as element lens systems) are initially set by a lens holding member having groove portions or hole portions extending in the direction of the optic axis, the distributions of intensity of light of the element lens systems on the image plane are controlled by an aperture eclipse such that the intensity of light is weaker in the marginal area than at least in the central area, a plurality of such element lens systems are arranged in a predetermined direction in a plane perpendicular to the optic axis and the distributions of intensity of light of the element lens systems are suitably superposed upon one another at least in the marginal area to provide uniformity of the distribution of the exposure amount integrated in the scanning direction with respect to the lengthwise direction of the slit of a copying machine of the slit exposure type. The element lens system each comprises two bar lenses each having a great length in the direction of the optic axis thereof as compared with the effective diameter thereof, and an intermediate image is once formed between the bar lenses and finally, a one-to-one magnification image is provided. The element lens systems are arranged in more than two rows in a honeycomb-like fashion such that the element lens systems of each row are positioned intermediate the element lens systems of the other row as viewed in the direction of the optic axis, whereby the uniformity of the distribution of the exposure amount integrated in the scanning direction with respect to the lengthwise direction of the slit is improved.
