Abstract
An information-code-image capturing apparatus operates for emitting light toward an article moving along a carry path, and receiving reflected light and capturing an image of an information code on the article. The information-code-image capturing apparatus includes a detecting device for detecting that the article reaches a predetermined position in the carry path. An image capturing device operates for capturing the image on the basis of the reflected light when a time interval has elapsed since a moment at which the detecting device detects that the article reaches the predetermined position. A positional information calculating device n operates for calculating positional information on the basis of the image captured by the image capturing device. The positional information enables an area of the information code to be determined in the captured image. A capture timing correcting device operates for correcting the time interval on the basis of the positional information calculated by the positional information calculating device.
