ABSTRACT:
A case has a front surface facing an image sensing area, a concave formed on the front surface, and an opening on the bottom of the concave. The case accommodates an area image sensor to image-sense the image sensing area through the opening, and an illumination device to illuminate the entire image sensing area. There are provided a photoelectric converting unit converting an output of the area image sensor into an electric image signal, and an output unit outputs an image signal converted by the photoelectric converting unit to an image processing device. The case also accommodates a lens to form an image of the image sensing area on the area image sensor with a depth of field so as to the image processing device obtain a resolution to enable analysis of a code symbol included in the image signal. A lens side limit position of the depth of field corresponds with the position of the front surface of the case.
