Abstract: An information code reader is capable of readably imaging an information code displayed on a screen, not liming to an information code covered by a covering portion through which visible light cannot be transmitted. In an information code reader, first illumination units to radiate visible light, in which an information code is subjected to image acquisition by a first image acquisition unit. Second illumination units radiate infrared light, in which the information code is subjected to image acquisition by a second image acquisition unit. A visible light cut filter, which does not allow the visible light to pass through, but which allows the infrared light pass through, is arranged depending on a spatial imaging range provided by the second image acquisition unit.

Abstract: In an optical information reader which optically reads an information code, a first polarizing unit arranged on the light-exit side of a lighting unit is configured to polarize illumination light therefrom in a predetermined polarization direction. In addition, a second polarizing unit arranged on the light-reception side of a light receiving sensor is configured as a switchable polarization unit, in which the switchable polarization unit is capable of performing a switchover between a polarized state in which light reflected from the information code is polarized in a direction different from the predetermined polarization direction and a passing state where the reflected light passes therethrough without being polarized.

Abstract: A charging system that performs power supply suitable for charging a capacitor of a portable terminal without being limited by the power supply capability of an external power source. The charging system includes a charging device that charges the portable terminal with power from an external power source such as a personal computer. This charging device includes a secondary battery and a power transmission coil. The charging device also includes a power supply control unit that performs: control of charging of the secondary battery with power from an external power source; and control of charging of the capacitor of the portable terminal via the power transmission coil with power from the secondary battery.

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 system contributing to prevention of unauthorized use of an information code displayed on a screen. In the system, an information code display device cyclically displays a plurality of partial code images on a display screen of a display unit based on a first rule when the first rule is received from a server in response to a first request to the server. Accordingly, an information code reading device captures images of the display screen at imaging intervals according to a second rule which is received from the server by in response to a second request to the server to decode an information code composed of the plurality of images thus captured, according to the second rule.

Abstract: An information reader includes a reader main unit and a case. The case houses therein an inner pad serving as an electrostatic capacity type of switch used by an operator to enable an information reading unit to read information. The inner pad is assembled within the case to be directed toward a touch detection region of the case. A switch unit, which is separated from the reader main unit, is provided with a touch electrode pad to which electrical charge is applied in response to an operator's touch operation, a wiring line one of whose both ends is electrically connected to the touch electrode pad, and a transmission pad to which the other end is electrically connected. The transmission pad is assembled with the case on the outer surface thereof.
