Abstract: In an information reader, a first relationship information, which defines the two-dimensional area of a first information code (e.g., the position coordinates of the four corner points), is detected from a first information code image. The first information code is subjected to reading information, based on the detected first relationship information. Parameters of a learning model are then adjusted based on training data including multiple successful cases of a reading process using the first relationship information. A second information code image captured by a camera is inputted to the learning model. A second relationship information, which is an estimated value of the information that defines the two-dimensional region of the second information code, is obtained from the learning model. The information recorded in the second information code is read based on the acquired second relationship information, thus reading results being outputted.

Abstract: A motor includes: a rotating shaft; a motor portion; a circuit board; a case having a circuit housing recess portion for housing the circuit board; and a cover made of a synthetic resin and sealing the opening portion of the circuit housing recess portion. The cover has an outer circumference rib and an inside rib. The outer circumference rib is located on the outer circumferential side from the opening end surface of the circuit housing recess portion and projects from the outer circumferential edge of the cover toward the front surface side of the cover and the rear surface side of the cover. The inside rib is located inside from the opening end surface and projects at least either on the front surface side of the cover or on the rear surface side of the cover.

Abstract: A two-dimensional code that is capable of suppressing unnecessary code detection processes related to detection of a code area is provided. Among outer edges of a rectangular code area, a first edge that is composed of a plurality of types of cells arrayed in a single row is configured such that a specific pattern that is composed of an array of two or more differing cells is repeated in at least an intermediate portion. A second edge composed of the plurality of types of cells arrayed in a row such as to oppose the first edge is configured such that the specific pattern is repeated in at least an intermediate portion.
