    摘要: A compound eye projection device includes a first lens and a second lens equal in shape and power. These two lenses are disposed with their optical axis being coincident with each other and together constitute an element lens system. A plurality of such element lens systems are arranged in a line form in a predetermined direction to thereby form a projection device.

    摘要: When a stationary beam is caused to impinge upon a deflecting mirror surface disposed parallel to the rotation axis of a deflecting mirror, from a finite angle with respect to a plane crossing both the rotation axis and the deflecting mirror at right angles therewith, the path of the scanning beam reflected from the deflecting mirror surface becomes conically shaped. This specification discloses a scanning device including a correcting optical element for changing the conical path of the scanning beam to a linear path.

    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.
