Title: Laser beam scanning device
Inventor: OMOTO SHUHEI
IPC: G03G15/04
Filed: 1989-08-25
Abstract: PURPOSE:To prevent a fault in detecting the write starting position of printing by forming the reflecting surface of a detecting mirror which reflects a part of laser beam reflected by a polygon mirror toward a photodetecting element to a concave surface having curvature with which the photodetecting element is brought into focus. CONSTITUTION:A part of reflected laser beam is made incident on the concave reflecting surface 19a of the detecting mirror 19 and reflected toward a photodiode 8. Therefore, the laser beam reflected in parallel with the exiting optical path of a laser diode 4 by the mirror 19 is made incident on the photodiode 8 to detect the write starting position of printing. When the optical path of the reflected laser beam made incident on a mirror 15 from a mirror 11 is deviated because of the face wobbling of a motor 10 or the surface inclination of the mirror 11, the incident light on the mirror 19 is also deviated. Since the reflecting surface 19a of the mirror 19 is formed of the concave surface having the curvature with which the diode 4 is brought into focus, the laser beam reflected by the mirror 19 is focused by the light receiving part of the photodiode 8 having the highest sensitivity.

Abstract: PURPOSE:To reduce the variation of beam width by the consumption of an electrode by nearly conforming the width of one electrode between two electrodes to the discharge width, and also arranging conductors on right and left both sides of the electrode in the longitudinal direction of, at least, one electrode. CONSTITUTION:The upper side is made a cathode electrode 12, which has a circular opposed face 12a, and the lower side is made an anode electrode 13, whose opposed face 13a is made in elliptic shape. In this case, metallic structures 14 are arranged on right and left both sides of the columnar electrode 13 for electric field relaxation are arranged at the cross section perpendicular to the longitudinal direction of the laser chamber of the electrode 13. By this electrode 14 for electric field relaxation, the electric field at the center of the anode electrode 13 or its vicinity is relaxed. Moreover, defining the short/long diameter ratio of the ellipsoid of the opposed face 13a of the anode electrode 13 that r=3, the electric field becomes uniform over the electrode width, and the discharge width approximately as long as the electrode width can be gotten. Accordingly, when laser operation is performed, the discharge widens approximately all over the surface of the elliptic part 13a of the electrode, and the consumption progresses at the same time. Therefore, for a long period, the uniform electric field can be maintained in the region prescribed by the electrode width.
