A commodity identification device is provided with: one or more processing devices; and one or more storage devices storing instructions for causing the one or more processing devices to: obtain a taken image; determine whether a commodity is provided with a corresponding mark or not by using a mark detector on the obtained taken image; identify which of a plurality of commodity groups a commodity provided with the mark belongs to by using a first neural network having learned the commodity, on the taken image where the mark is detected; and identify the commodity by using a second neural network having performed learning for each of the commodity groups.

Commodity identification device, non-transitory computer-readable storage medium, and learning method

A pattern phase difference film is manufactured by a process including a laminate body formation step of applying a pattern alignment layer composition on a substrate to form a laminate body, a heat-drying layer formation step of heat-drying the composition to form a heat-dried layer, a pattern alignment layer formation step of irradiating a polarization pattern onto the heat-dried layer to form a pattern alignment layer, and a phase difference layer formation step of forming a phase difference layer including a rod-shaped compound on the pattern alignment layer. During the steps between the heat-drying layer formation step and the phase difference layer formation step, the heat-dried layer and the pattern alignment layer are exposed to the air for four hours or less.

A method for producing an optical orientation film is disclosed, the method being able to realize highly accurate exposure in a pattern, even if a simple device and non-parallel light are used and a long continuous resin substrate is used and fed continuously. The method for producing the optical orientation film includes the steps of: (i) preparing an irradiation target substrate and a long continuous photomask (ii) feeding the irradiation target substrate continuously; (iii) feeding the photomask continuously; (iv) producing a laminate by laminating the photomask fed in step (iii) on an orientation layer of the irradiation target substrate fed in step (ii); (v) exposing the orientation layer in the pattern by irradiating with light, while feeding the laminate obtained in step (iv) in the longitudinal direction of the laminate; and (vi) removing the photomask from the laminate irradiated in step (v).
