    摘要: A scanner for reading an object having a width larger than that of the distal end portion of a scanner main body, has an exit opening for outputting a light beam formed at the distal end portion of the scanner main body. An LED for generating a light beam, and a solid-state image pickup element for receiving the light beam which is reflected by the code, are arranged in the scanner main body. A gap portion for increasing the irradiation width of the light beam to be larger than the width of the distal end portion of the scanner main body is formed at the distal end portion of the scanner main body. Therefore, when a code is read by bringing the scanner main body close to or into contact with the code, the gap portion increases the width of the light beam to be larger than that of the distal end portion of the scanner main body, and therefore, a code having a width larger than the width of the distal end portion of the scanner main body can be read.
