Abstract
A two-dimensional code reading device which can prolong the lifetime of the auxiliary light is provided. A two-dimensional code reading device in the present invention includes an image reading unit to acquire an image of a two-dimensional code printed on a ticket medium, a specific pattern detector to detect a specific pattern to identify the two-dimensional code from the image of the two-dimensional code acquired by the image reading unit, a two-dimensional code decoder to read information recorded in the two-dimensional code detected by the specific pattern detector, an auxiliary light to irradiate light on the ticket medium and an auxiliary light controller to control turning on and off of the auxiliary light, wherein the auxiliary light controller turns on the auxiliary light when the specific pattern is detected by the specific pattern detector and the information recorded in the two-dimensional code cannot be read by the two-dimensional code decoder.
