Title: Light deflecting scanner
Inventor: TANAKA YOSHIHIKO
IPC: B41J2/44
Filed: 2001-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a light deflecting scanner where soiling of a scanning lens due to air flow generated by rotation of a rotating body is remedied. SOLUTION: In the device, space 100 with an opening part opened on a polygon motor side 20 is provided below a scanning lens 30 with a bottom surface of the scanning lens 30 and surfaces 1 and 2 forming an optical box. Therefore, dust and dirt contained in the air flow can be trapped in the space 100 and even when a part of the air flow is flown out of the space 100 and passes by an effective surface 30a of the scanning lens 30, since the passed quantity of air flow is small, the dust and dirt contained in it is minimized. As a result, the soiling of an effective surface 30a of the scanning lens 30 by dust and dirt can be greatly remedied and a bright image without any unevenness in density can be obtained.
