Document Type and Number:
Japanese Patent JPS6477367
Kind Code:
A
Abstract:
PURPOSE:To properly read out an image even when a large film is used by arranging a light beam dividing means for dividing light projected from a photographing lens into plural beams between the photographing lens and photodetecting elements and arranging the photodetecting elements so as to receive respective divided beams. CONSTITUTION:The photodetecting elements CCD 402, 403 are respectively arranged so as to receive respective two beams divided by a half mirror 401 to be the light beam dividing means. One element 402 is arranged on the back area of the half mirror 401 and the other 403 is arranged on the lower area of the half mirror 401 so that each element receives a part slightly wider than a half of a light beam projected from the half mirror 401. Thereby, an expanded image of a microfilm image is projected to respective effective picture element arrays of respective photodetecting elements 402, 403 so as to be partially overlapped. Consequently, no omission is generated on a reading image in a scanning direction.
