  • Patent number: 11070695
    Abstract: An image reading device includes a reading unit that reads a document sheet and a reading standard surface and outputs read values corresponding to pixels arranged in a main scan direction, a control unit that processes the read values, and a storage unit storing information to be referenced by the control unit. In the storage unit, first data that is read values of the reading standard surface and serves as standards, and second data on ranges of variation, based on a change in a temperature, in the read values are stored. The control unit determines, based on the first data and the second data read from the storage unit and third data obtained by reading the reading standard surface after an acquisition of the first data, whether an abnormality exists in the pixels.

  • Patent number: 10804720
    Abstract: A battery charging apparatus that acquires a remaining battery charge amount by detecting a battery voltage after charging of a battery by a charging circuit has been temporarily stopped and a given wait time has elapsed, wherein, regardless of the temporary stopping of charging by the charging circuit, a charging display control unit that controls display of a charging displaying section causes the charging displaying section to display that charging control is being performed while charging control is being performed.

  • Patent number: 8607975
    Abstract: An electronic device can be inserted into a pocket formed with a main cover through between a side cover and the main cover. A part of the electronic device where an operating stick is formed can be stored in a flap formed with the side cover. The upper end of the flap rim of the side cover is positioned further away from the center line C1 of the case than the lower end is. The pocket rim of the main cover gets closer to the center line C1 of the case as it goes from the upper end to the lower end. According to a case including the main cover and the side cover, insertion/removal work of the electronic device can be facilitated, undesired exposure of the electronic device can be prevented, and a load applied to the operating stick can be readily reduced.

  • Publication number: 20130040088
    Abstract: A film laminate (1) includes a base film (10) and a protection film (2). The base film (10) has positioning parts (11a to 11c) formed thereon that are holes or notches into which operation buttons (91A to 91C) of the electronic device (90) can fit and which is for defining the position of the film laminate (1) on the front surface of the electronic device (90). By the film laminate 1, when a user attaches a protection film to an outer surface of an electronic device, displacement of the film laminate on the outer surface can be prevented, and thereby attachment work of the protection film can be facilitated.
