Information reader

An information reader, comprising:

• a camera imaging a two-dimensional information code;
• a first code process execution unit configured to perform a first code process, the first code process includes
• a detection process detecting a first relationship information defining a two-dimensional code area of the first information code from an image of a first information code which serves as the information code imaged by the camera;
• a reading process reading information recorded in the first information code based on the first relationship information which has been detected;
• an adjustment unit configured to adjust learning model parameters based on training data including, at least, a plurality of successful cases of the reading process read based on the first relationship information, the learning model parameters being for outputting second relationship information shown by estimated values of information defining a two-dimensional code area of the information code from the information code imaged by the camera;
• and
• a second code process execution unit configured to execute a second code process, the second code process includes
• an acquisition process acquiring inputting, into the learning model, an image of the second information code, which serves as the information code imaged by the camera, and acquire the second relationship information from the learning model;
• a reading process reading information recorded in the second information code based on the second relationship information which has been acquired;
• and
• an output process outputting a reading result of the reading process.
