  • Publication number: 20170152118
    Abstract: The present invention is to provide a sheet aligning apparatus that is capable of detecting misalignment. A control portion of a post-processing apparatus causes a front aligning member and a rear aligning member to be moved to an aligning position to align sheets conveyed to a processing tray, causes the front aligning member to be moved from the aligning position to a detecting position, and determines whether an electrostatic capacitance sensor detects misalignment (sheet shifting from a sheet bundle). When it is determined that the senor detects misalignment, the front aligning member is moved from the detecting position to the aligning position so that sheets are realigned.

  • Publication number: 20120231727
    Abstract: An association unit associates earthquake disaster information that a governmental agency, a municipality, or the like publishes with base station data including position information of base stations. A base station priority calculation unit, based on an association result by the association unit and the estimated number of users that are present in coverage of each of the base stations, assigns priority for recovery measures at the time of an earthquake disaster to the base stations, and causes a display unit to display the priority of the base stations thus calculated. Thus, it becomes possible to easily assign the priority of the base stations based on the earthquake disaster information that a governmental agency, a municipality, or the like publishes.
