  • Hand-held scanner having a folded optical path providing a compact design
    Patent number: 5489770
    Abstract: In an optical information reading apparatus in which the degree of freedom with which the apparatus is shaped is improved, a mirror for bending a reflected light which has passed through an image forming lens is disposed between the image forming lens and an image sensor, whereby the provision of the image sensor at a position which is not on a line extending between the image forming lens and the mirror is enabled. That is, a space located beyond the line extending between the image forming lens and the mirror can be freely altered, thus increasing the degree of freedom with which a casing is shaped.
