<p>PROBLEM TO BE SOLVED: To provide a floor-standing type information code reader capable of keeping the entire thickness of the reader small, easily securing a wide region in which information code can be imaged near a reading port, and more easily reducing the influence of noise light.SOLUTION: If it is assumed that a position symmetrical to a principal point Pa of a visual field range is a first virtual principal point Pb1 while a position of a reflection surface 29a is a center line, a position symmetrical to the first virtual principal point Pb1 is a second virtual principal point Pb2 while a position of a lower surface of a plate 7 is a center line, and a position symmetrical to the second virtual principal point Pb2 is a third virtual principal point Pb3 while the position of the reflection surface 29a is the center line in a cut plane cut by a plane passing through cutting a first optical axis L of a first visual field range AR1 and a second optical axis L2 of a second visual field range AR2, a reader 1 includes a reflector member 29 arranged at a position deviating downward from a first line La1 starting at the third virtual principal point Pb3 as an origin and passing through one opening end portion 5d of a reading port 5.</p> |
