  • Patent number: 10891454
    Abstract: An information reading apparatus includes an information reading section, a communication section, a memory, a first determination section, a second determination section, and a control unit. In the apparatus, every time data is determined to be unread data (i.e., data read by one information reading apparatus but not shared yet by all of a plurality of information reading apparatuses) by the first determination section, the control unit records the unread data in the memory, while transmitting the unread data to other information reading apparatuses through the communication section. The control unit also records data determined to be unread data by the second determination section in the memory. A plurality of such information reading apparatuses are employed in an information reading system in which each information reading apparatus can easily keep track of the entire progress of reading tasks.

  • Patent number: 10878400
    Abstract: In the mobile terminal, a first information code is generated based on a terminal identification information and first determining information. The generated first information code is displayed by display unit provided in the mobile terminal. In the mobile terminal, the first and second determining information are acquired from a payment apparatus through reading a third information code. Based on the second determining information, a second information code is generated. Responsively to this generation, images presented on the display unit's screen are updated from a state where the first information code has been displayed so far to another state where the second information code is displayed. In a payment apparatus, an imaging unit images the second information code providing the decoded second determining information, followed by imaging first information code, further followed by performing a process based on the terminal identification information decoded together with the first determining information.

  • Publication number: 20200393645
    Abstract: An optical information reader includes an imaging lens and a lens retainer retaining the imaging lens and assembled, in this state, into the holder. The lens retainer includes a flange bottom surface and end faces as a reference surface that is parallel to an optical axis of the imaging lens. The holder includes a top surface and edge faces as a guide surface. The guide surface is brought into surface contact with the flange bottom surface and the end faces when the lens retainer is assembled into the holder, and is brought into slidable contact with the flange bottom surface and the end faces when the lens retainer is moved along the optical axis. Thus, influence of one-sided blur is minimized in terms of variation in resolution which is measured when obtaining an optimal focus position by changing relative positions of the area sensor and the imaging lens.

In the apparatus, an axis setting section sets operation axes and control axes from among the axes subjected to angle control, when performing the direct teaching of changing a position of the arm tip, while retaining a posture thereof at a target posture. The operation axes can be dominant factors when determining the position of the arm tip and are allowed to freely move according to an external force, and the control axes can be dominant factors when determining the posture of the arm tip and are controlled by an angle control section. When performing the direct teaching, the angle control section receives an input of current angles of the operation axes and the target posture to calculate command angles of the respective control axes according to inverse kinematics calculation.

  • Patent number: 10769397
    Abstract: An optical code is readable by a generally used reading device, and optically readable as an information code that can appropriately prevent abuse due to duplication. In this optical code, data is recorded with a pattern of a plurality of light-color modules having high visible light reflectance and a plurality of dark-color modules having visible light reflectance lower than light-color modules. At least either the light-color modules or the dark-color modules are configured to include a first module and a second module having reflectances different from each other for invisible light of a predetermined wavelength. Thus, data is recorded as a readable pattern of modules, the pattern being differently observed between when irradiated with visible light and when irradiated with the invisible light of a predetermined length.

  • Patent number: 10762729
    Abstract: A wireless card reader system includes: a card reader terminal that is battery-driven and obtains card data for verification; a high-order host apparatus that verifies the card data, changes an operating state of a target device when a verification result is successful, and sends the verification result; and an interface apparatus that relays communication between the card reader terminal and the high-order host apparatus. The card reader terminal is operable in a normal mode or in a sleep mode. The card reader terminal switches to the sleep mode after sending the card data in the normal mode. The card reader terminal temporarily returns from the sleep mode to the normal mode to perform polling to the interface apparatus, and obtains the verification result. The polling is performed less frequently in a period before a state change than in a period after the state change.

    Abstract: An input/output module includes a control unit and a monitoring unit. The monitoring unit includes a series-connection body including three or more resistors, a comparator, a connection path, and a switch. One of inverting and non-inverting input terminals of the comparator serves as a monitoring terminal, and the other serves as a threshold terminal. Input voltage of the threshold terminal when the switch is turned off is set to a high-voltage-side threshold, and the input voltage when the switch is turned on is set to a low-voltage-side threshold. The control unit makes a diagnosis that an abnormality in which the power supply voltage falls outside of an operable voltage range or an abnormality in the monitoring unit has occurred, when logic of an output signal of the comparator is determined to be unchanged over a determination time that is a longer amount of time than a predetermined amount of time.
