Title: Optical scanner
Inventor: HATTORI YUTAKA
IPC: H04N1/113
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To accurately and distinctly acquire image information by providing such an image formation means that the beam diameter of reflected light by a detection means is made an optional diameter less than or equal to the width of a detection surface. SOLUTION: As for respective photodetector parts; light receiving area is made small in order to secure the high speed responsiveness of a photodiode, and detection lenses are respectively arranged between an original and the photodiodes 7a... in order to efficiently make the reflected light from the original incident on the photodiodes. As for the detection surface of the photodiode 7a; its length (detection surface width) in a direction orthogonal to the operating direction of a spot is set longer than its length (detection surface length) in a scanning direction. To put it concretely, the detection surface width is set to be nearly equal to a spot diameter (w) in order to obtain the optimum detection surface. Namely, the detection surface of the photodiode is arranged only in an area where the spot scans.
