摘要： PURPOSE:To realize a cost-saving and space-saving device by making one picture recording device have both functions of silver salt recording and non-silver salt recording. CONSTITUTION:A laser beam from a laser light source 8 is reduced to a suitable beam diameter by convex lenses 9, 10, and a beam intensity is modulated by a picture signal by an A/D converter 11. As for this beam, the beam diameter is expanded by an expander 12, and since that which is used for recording generally is a primary light, a zero-order light is eliminated by a light shielding blade 14. The laser beam is further led to a projection lens 6 through a rotary polygonal mirror 7, made incident on a silver salt film 1 and a silver salt film recording is executed. In this case, when a unit 5 is moved to a position shown by 5a, the laser beam is led to a xerography photosensitive drum 4 and a zerography recording can be executed, and a cost-saving and space-saving device can be realized by making it have both functions of silver salt recording and non- silver salt recording.

摘要： PURPOSE:To perform optical scanning roughly from a perpendicular direction and to obtain a distortion-free image with high accuracy, by moving a light source part and a scanning deflector in parallel along the plane of an image storage plate without inclining the shaft of the scanning deflector. CONSTITUTION:The light beam L from a light source 6 is imaged onto an image storage plate 1 by a condenser lens 9, a mask 10, a collimator lens 11, a rotary polyhedral mirror 7 and a lens 8. If a feed shaft 3 is rotated by a driving mechanism consisting of an electric motor 2, a moving base plate 5 moves, for example, downward. Therefore, the optical scanning to the plate 1, i.e., the main scanning in a Y-axis direction is accomplished by the rotation of the mirror 7 and the subscanning in the Z-axis direction of an arrow B is accomplished by the downward movement of the plate 5. Since the incidence of the beam L to the plate 1 projected on the X-Z plane is roughly perpendicular, the distortion- free image is obtainable. The diagonal incidence of the beam L to the plate 1 owing to a change in the angle of deflection with the optical scanning is corrected by the lens 8.

摘要： PURPOSE:To perform optical scanning on an image storage plate from roughly a perpendicular direction and to obtain a distortion-free image with high accuracy, by moving a scanning deflector along the plane of the image storage plate without inclining the shaft thereof. CONSTITUTION:The light beam L from a light source 8 is scanned on an image storage plate 1 by a condenser lens 9, a mask 10, a collimator lens 11, mirrors 12, 5, a rotary polyhedral mirror 6 and a lens 7. As the mirror 6 rotates, the beam scans the surface of the plate 1 horizontally on the X-Y plane. If a feed screw bar 2 is rotated by a driving mechanism in this stage, a base plate 4 moves downward and the optical systems 5, 6, 7 on the plate 4 moves downward as well. The optical system from the light source 8 up to the mirror 12 is fixed but the light are parallel thereafter and therefore even if the distance between the mirrors 5 and 12 changes, the beam L is made incident to the mirror 7 irrespectively of the distance. The main scanning in the Y direction on the plate 1 is accomplished by the mirror 6, and the scanning in the Z direction is moved by rotating a shaft 2.

摘要： PURPOSE:To make it easy to discriminate a focus direction with respect to lenses of all aperture ratios and to drive a lens so that an effective focusing detection can be executed, by adopting the merits of a contrast method and a correlation method. CONSTITUTION:A photographic lens 1 forms an image on a film surface 2. In this case, a focusing detection in a center luminous flux 7 is executed by comparison of a photodetecting quantity of line sensors 5a, 5b of a CCD, etc. provided by shifting front focusing and rear focusing by an equal quantity on a photodetector 5 through a lens 3 and a split prism 4. That is to say, with respect to the center luminous flux, the focusing detection is executed by a contrast method. Peripheral luminous fluxes 8a, 8b are made to go toward an image sensor 5 conjugate with the film surface 2 by rod-like lenses 6a, 6b. The rod-like lenses 6a, 6b form an intermediate inverted image once by power of the first surface of the lens, and form an erect image again by power of the second surface of the lens. In this case, by setting the rod-like lenses 6a, 6b diagonally against the optical axis, an interval of two separated points on the line sensor 5a does not become so large, and as for the size, a line sensor being on the market is enough.

摘要： PURPOSE:To eliminate distortion in a subscanning direction by running a scanning plural times by the rotary movement of one mirror surface and holding the inclination of the subscanning direction of a scanning beam to a scanned surface nearly at the right angles and moving an optical scanning system in the subscanning direction. CONSTITUTION:When the light transmission part of a beam splitter 4 rotates until luminous flux 2 strikes it while the light beam pass through a point 41 to make an ineffective scan, the luminous flux 2 is transmitted through the light transmission part of the beam splitter and reflected by a fixed reflecting mirror 7 to strike a surface 8 of a rotary polygon mirror which still rotates and reflected the luminous flux previously at a different angle again; and the luminous flux is reflected there to form an image on a detection plate 30 through an ftheta lens 9, making the 2nd photoscan. Then, when light forms an image at a point 40 and the 1st photoscan is made toward the right side in a figure, a moving substrate 37 moves continuously at an equal speed in the subscanning direction shown by an arrow by rotating screw 44.

摘要： PURPOSE:To perform plural times of scanning with one turning movement of a specular surface by making the light beam entering a rotary polyhedral mirror incident time dividedly to different beam paths. CONSTITUTION:When laser light is reflected by a beam splitter 4 and advances in a direction 2a, and if the angle between the luminous flux 2a thereof and the face 8 of a rotary polyhedral mirror 6 is 45 deg., the light is reflected by the face 8, advances in a direction 3b and forms its image on an imaging plane O. If the face 8 of the mirror 6 is located at 11 deg. before the same, the image is formed on an imaging plane 12. When the angle between the light 2a and the face 8 advances further from 45 deg. to 56 deg., the image is formed on an imaging plane 13. When the mirror 6 is rotated non-effectively by 8 deg. rotating angle, the light 2b heading through the mirror 7 toward the mirror 6 falls onto the face 8 of the rotary mirror and is reflected in the direction of light 3a, drawing the same main scanning line as the light 2a. The efficiency is higher than in the case in which the light is made incident to the polyhedral mirror from one direction only.
