Title: Laser scanning system
Inventor: SHIRAISHI TAKASHI
IPC: G02B26/10
Filed: 1987-05-01
Abstract: PURPOSE:To prevent a laser beam which is reflected by the photodetection surface of a photodetecting element from striking a photosensitive body stray light by slanting the photodetection surface at a specific angle in the opposite direction from the scanning system side of a laser printer. CONSTITUTION:It is assumed that the laser beam l1 which is reflected by a return mirror 56 for horizontal synchronism is incident on the photodetection surface of the photodetection part 84 and the laser beam l2 is reflected by the photodetection surface returns to the mirror 56. When the angle between those laser beam l1 and l2 is denoted as theta, the surface of the photodetection part 84 is slanted to the housing side wall side of the return mirror 56 by >=theta/2 based upon the surface of the photodetection part in the state wherein the laser beam l2 returns to the mirror 56. Consequently, the laser beam l4 which is reflected by the photodetection part 84 is incident on the side wall side of the housing without returning to the return mirror 56, and is prevented from impinging on a photosensitive body as stray light.

A multiplier means 2 multiplies a prescribed coefficient with a picture data outputted from the matrix means 1. When the monochromatic color edit processing is not commanded by the control signal, a coefficient to bring the toner signal outputted from the matrix means 1 to 'through' state is multiplied and when the monochromatic color edit processing is commanded by the control signal, four coefficients corresponding to the color commanded by the control signal are multiplied with the inputted luminance signal L* to generate four toner color signals Y, M, C, K. The four coefficients have a data form of coverage of the Y, M, C, K signals.

This is easily formed by separately shifting the centers 0, 0', of the groove 2 and the ring 3. Then, the metallic fine grain 8 is fed from the side of larger sectional area into the forming path 7, and is taken into the side of smaller sectional area, depending on the friction between the metallic fine grain 8 and the internal wall of the groove 2, being caused by the rotation of the wheel 1 in the arrowed direction; through this process, the metallic fine grain 8 is compressed to form a long, flat type wire material. Hereupon, the angle of bite, dicided depending on the relation among the groove 2, the ring 3 and the fine grain 8, becomes large structurally.
