    摘要: A drawing surface adjusting mechanism for use with a scanning pattern drawing apparatus capable of not only moving a drawing board in a vertical direction but also tilting it, whereby the chance of bringing the drawing surface within the depth of focus of a scanning lens is increased even if the drawing surface has waviness or other flaws within the width of a single storke of scanning. The drawing surface adjusting mechanism of the invention includes a drawing board for supporting a workpiece that is to be scanned with a scanning optical system by means of a unidirectionally tracing light beam, transport means for allowing the drawing board and the scanning optical system to slide relative to each other in a direction that crosses the direction of beam tracing at right angles, a first and a second drive mechanism which are spaced apart in the tracing direction and which move one side of the drawing board in a direction parallel to the direction of the beam, tilt control means for inclining the drawing board with respect to the transport means by making the drive amount of the first drive means different from that of the second drive means, and translation control means for effecting a translational movement of the drawing board with respect to the transport means by making the drive amount of the first drive means equal to that of the second drive means.

    摘要: A scanning optical system has a drawing light source, a rotary scanning deflector, a scanning lens and a detection device for detecting a rotational position of the scanning deflector. The drawing light source is controlled by a timing control signal generated by a timing control device as a function of drawing data. The scanning optical system may have a transmission scale, a scanning light receiving portion and a diffusion plate disposed between transmission scale and scanning light receiving portion and adapted to diffuse the monitor beam made incident to the scanning light receiving portion.

    摘要: A light source control apparatus comprises light source means for producing first and second beams, a first scan surface to which the first beam is applied, a second surface to which the second beam is applied, scanning means for causing the first and second beams to scan the first and second surfaces, respectively, a fluorescent optical fiber disposed along a scanning direction of the second beam for emitting fluorescent light in response to the second beam incident thereto and transmitting the fluorescent light, and photodetecting means for detecting the fluorescent light. A part of the outer surface of the fluorescent optical fiber can be the second scan surface which has alternately arranged transparent regions and opaque regions, thereby further reducing the number of components of the apparatus.

    摘要: A light beam emitted from a light source such as a semiconductor laser, is irradiated onto a recording section such as a photosensitive drum, through a scanning section composed of a rotary polygonal mirror. In a predetermined position in a plane formed by the scanning light beam, a columnar fluorescent optical fiber is arranged perpendicular to this plane, containing fluorescent substances therein. The fluorescent substances generate fluorescent light when the light beam is incident onto these fluorescent substances which is received by the photodetector arranged on the end face of the fluorescent optical fiber. As a result, even when a reflecting face of the rotary polygonal mirror is inclined irregularly, the light beam is incident to the fluorescent optical fiber so that it is not necessary to adjust the position of the fluorescent optical fiber.
