  • Patent number: 11967294
    Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.

  • Patent number: 9799022
    Abstract: In an information processing device (settlement terminal device), a first main body that accommodates a first information processing unit in a first housing including a first input display unit (first touch panel), and a second main body that includes a second housing from which a seat unit for detachably attaching the first main body extends, and accommodates a secure second information processing unit which includes a second input display unit (second touch panel) disposed in the second housing to be on the same plane as that of the first input display unit of the first main body attached to the seat unit, and which has tamper resistance, are provided. In the information processing device, the first input display unit and the second input display unit are preferably arranged on the same plane. A secure portion can secure physically high tamper-resistance performance and the high robustness of the entire device.

  • Patent number: 9773131
    Abstract: An information processing device includes a non-secure information processor and a secure information processor that are each accommodated in a housing. A first input display and a second input display are each provided on an operational surface of the housing. A boundary is between a first end side of the housing and a second end side of the housing, with the second end side of the housing being opposite to the first end side of the housing across the first input display and the second input display. A color or a surface treatment of a first portion of the first end side of the housing corresponding to the non-secure information processor is distinguishable from a color or a surface treatment of a second portion of the second end side of the housing corresponding to the secure information processor.

  • Patent number: 9607181
    Abstract: An information processing device includes a first information processing unit that is accommodated in a housing, and in which a first input display section is provided on an operational surface of the housing, and a tamper-resistant secure second information processing unit that is accommodated in front of the first information processing unit in the housing gripped by an operator, and in which a second input display section is provided in front of the first input display section on the operational surface. Further, in the information processing device, for example, a secure state display section that indicates a secure mode in authentication input, or indicates a non-secure mode in a case other than the authentication input is disposed on the operational surface. Even when a secure portion and a non-secure portion are present together, security of authentication information is secured, and an operator's mistake or an incorrect operation is suppressed.

  • Publication number: 20110228354
    Abstract: A document reading device (1) comprises: a camera (3) for taking an image of an information recorded surface of a passport (P) on which information that can be read through use of light of a predetermined reading wavelength is recorded; an illumination unit (4) for providing illumination of the reading wavelength toward the information recorded surface; an LED (8) for emitting detecting light for the passport (P) from a back of the information recorded surface, the detecting light being of a detecting wavelength different from the reading wavelength; and a control unit (9) for controlling document detection by the camera (3) and light emission by the LED (8). The document reading device (1) detects that the passport (P) is in place based on a brightness level of the detecting light from the LED (8) at the time of imaging. The detecting light emission from the LED (8) is controlled to turn off once the document is successfully detected.
