  • Image reading apparatus
    Patent number: 5394205
    Abstract: An apparatus comprises an image sensing optical system including an image pickup element for converting an image to an electrical signal and a projection lens for projecting an image onto a photo-sensing plane of the image pickup element. The image sensing optical system is driven along an optical axis thereof while maintaining a relative positional relationship between the projection lens and the image pickup element to adjust the focal position. An apparatus may also comprise an image sensing optical system including an image pickup element for scanning an image to convert it to an electrical signal and a projection lens for projecting an image onto a photo-sensing plane of the image pickup element, a focus adjusting device for adjusting a focal position of the image sensing optical system and a detector for detecting an in-focus position of the image sensing optical system to the object.
