<p><P>PROBLEM TO BE SOLVED: To provide an optical information reader automatically stopping the outgoing of a laser beam while the optical information reader does not perform a reading operation. <P>SOLUTION: When whether the optical information reader is in an incident state in which an external light from the outside of a casing 11 is made incident on a plurality of opening parts 51 to 57 formed in a grip part 50 of the casing 11, is detected for each of the opening parts, a gripping state in which the grip part 50 is held is estimated on the basis of each of the incident states. When it is not determined that the reader is performing a reading operation on the basis of the estimated gripping state and an outgoing direction detected by an outgoing direction detection mechanism 70, the outgoing of a laser beam Lf by a light source 21 is stopped. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
