Abstract
To simplify a data reading apparatus for two-dimensional code data, a line sensor detection unit (30) for reading two-dimensional data includes an optical fiber band cable (3) bundling multiple optical fibers (31) of specified diameter in a band, and an upper end of the fibers is connected to a line sensor element (2) unit incorporated in the reading apparatus (S), and a lower end of the fibers is disposed opposite to an opening (11) of a specified size in the region of one or more two-dimensional code data in the bottom of the reading apparatus (S). The line sensor detection unit (3) including the optical fiber band cable (3) is disposed reciprocally parallel along the surface to be detected in an orthogonal direction, and the line sensor detection unit (30) is set movable within the range of the opening (11). A detection unit moving device (4) is disposed so as to read the two-dimensional code data. As a result, recorded two-dimensional code data can be read by a line sensor for reading one-dimensional data, so that high reading precision can be maintained and the product cost of the reading apparatus of the two-dimensional data can be reduced.
