Title: Optical beam recording device
Inventor: OKINO YOSHIHARU
IPC: B41J2/44
Filed: 1993-05-24
Abstract: PURPOSE:To obtain an optical beam recording device wherein a part of three- color light sources can take an independent optical path without causing any color shift, and the degree of freedom of the layout of the device can be increased. CONSTITUTION:The optical path of an SHG (a laser beam output element) 16 is different from the optical path of a semiconductor laser 14 and from that (an optical path refracted by a dichroic mirror 34) of an SHG 18 and forms an optical path linearly reaching a polygonal mirror 44. Therefore, a Y-color developed by the laser beam outputted from the SHG 16 may cause a color shift against other colors. However, the Y-color has the nature hardly recognizable with human's visual sensation, and, since the color shift is allowable up to the extent of 60mum, the substantial deterioration of the image quality is not caused by changing the optical path of the SHG 16. On the contrary, the constructional, layout of an optical beam recording device becomes free because the optical path can be changed, and the layout that enables the recording device to reduce its dimensions and improve its maintenance can be designed.

Thus, a common emitter amplifying circuit is constituted; and the resistance R1 is equalized to the resistance R2 and the resistance R3 is set sufficiently large to allow an output voltage V0 to have linear relation to an input voltage VIN. Thus, distortion reduction and stability are realized without providing negative feedback through an open loop.
