IPC: G02B6/28
Filed: 1980-07-02
Abstract: PURPOSE:To allow an allocation ratio to be changed easily and to improve the productivity by arranging a parallelogram prism in a part of light flux. CONSTITUTION:When a corner part 18a of a parallelogram prism 18 is interposed partially to light flux 30 from a focusing type lens 12, a part of the light flux enters the interior of the prism 18 from a long side 18a near the corner part 18e, reflected totally at short sides 18c and 18d and guided to a focusing type lens 14 passing through a long side 18b. The remaining light flux 32 among the light flux 30 that does not enter the prism 18 is led to a focusing type lens 13. When the parallelogram prism is shifted in the direction perpendicular to a light axis of the light flux 30, an amount of interposition of the corner part 18e to the light flux 30 can be changed and an allocation ratio of the light flux can be easily varied.

Title: Method and apparatus for formation of image
Inventor: ANDO YUJIRO
IPC: H04N1/23
Filed: 1992-04-10
Abstract: PURPOSE:To form images in high density at high speed by a method wherein the position of a microspotlight is placed approximately in the middle of two lines when the images are formed to pixels in the two lines in parallel in the horizontal scanning direction, and is placed approximately at the center of the image line when the images are formed to either one of the pixels and at the same time, exposure is decreased. CONSTITUTION:In scanning in the horizontal scanning direction, the scanning is made simultaneously for two lines. As operation for image formation starts, a control device reads write-in information about two pixels adjoining each other in the vertical scanning direction out of pixels in two lines from an image storing means, and executes fine controls, through a vertical scanning polarization element 3, on the position of a microspotlight in the vertical scanning direction in accordance with the write-in information of each of the pixels, and also controls the state of emission from a semiconductor laser 1. Namely, in the case where both of the two pixels in two adjacent lines are written in, the semiconductor laser 1 is put in the state of continuous emission, and the microspotlight is placed approximately in the middle of the two lines. In the case where either one of the two adjacent pixels is written in, the semiconductor laser is put in the state of pulsative emission, and the microspotlight is placed at the center of the pixel for which writing-in is executed.
