求の範囲第(1)項記載の文字読取装置。[Claims for Utility Model Registration] (1) In a character reading device that reads information with a camera using a two-dimensional solid-state image sensor, an annular fluorescent tube that illuminates a recording surface on which the information is written is connected to the recording surface. A character reading device characterized in that the character reading device is arranged at a position surrounding an optical axis connecting the lens of the camera. (2) The annular fluorescent tube is arranged so that its center position is offset from the optical axis by a predetermined distance, and the distance between the plug and the optical axis is greater than the distance between the light emitting part and the optical axis. A character reading device according to claim (1) of the utility model registration claim.
