| 英文摘要 | PURPOSE:To prevent the deterioration of image quality by integrating the laser diodes (LDs) which are the light sources of a laser beam and the driving circuit substrate thereof and outputting the signals corresponding to the screening classes relating to the diversion angles of the laser beams of the LDs from the integrated driving circuit substrate to a light quantity control section. CONSTITUTION:The circuit which outputs the signals corresponding to the classification of shading rates by the fluctuations in the diversion angles, for example, ID2-ID3; for each of the LDs is provided to the LD driving circuit substrate 29. Jumper lines J1-J3 are prepd. for this purpose and the respective jumper lines of terminals 39 and 40, 41 and 42, 43 and 44 are connected or not connected as shown in the figure by dotted lines to output the class of the laser unit 15 as the electric signals (combination of ID1-ID3) via resistors 45-47 to the outside. The shading is equivalently eliminated in this way by executing the light quantity control by the ID signals and the coincidence signal COMS of a comparator 38, by which the image parts are improved. |
