Zusammenfassung:	The utility model relates to a device for reading an image, in particular to a contact-type image sensor provided with an ultraviolet light linear light source which is a light guide body type. The contact-type image sensor is provided with a frame; a circuit board is arranged under the frame and provided with a photoelectric conversion chip; a lens is installed above the photoelectric conversion chip, and the side of the lens is provided with the light source; and a glass plate is arranged above the frame. The image sensor is characterized in that the side of the lens is provided with the linear light source formed by an ultraviolet LED, a light guide body and the LED circuit board, and the ultraviolet LED is arranged at the end part of the light guide body. The contact-type image sensor has the advantages of low cost and energy consumption, high uniformity and sensitivity for identifying ultraviolet information, and the like.
