  • Patent number: 9359158
    Abstract: A sheet feeding device includes: a sheet stacking member; an air blowing unit configured to blow air onto the sheet bundle placed on the sheet stacking member to suspend multiple sheets of the sheet bundle; a lifting/lowering unit configured to lift/lower the sheet stacking member; an optical reflection sensor configured to detect a suspended sheet suspended by the air blowing unit; and a control unit configured to control the lifting/lowering unit based on an output value of the optical reflection sensor. The optical reflection sensor is configured to be capable of detecting an area corresponding to multiple sheets in a sheet suspension zone extending between a non-suspended sheet bundle and a conveying member configured to convey an uppermost sheet of the multiple suspended sheets. The non-suspended sheet bundle is made up of sheets not suspended during a period when air is blown by the air blowing unit.

  • Publication number: 20160107853
    Abstract: Provided are a floating restricting member restricting the floating position of a bundle of sheets; and a holding mechanism holding the floating restricting member relative to a side fence. The floating restricting member includes a sheet contact section being brought into contact with the sheets from above; and a sheet-floating restricting section restricting the floating position of the floating sheet that is floated while air is blown thereto. The holding mechanism sets the floating restricting member in the initial state where the sheet-floating restricting section restricts the floating position of the sheet, in the sheet-placing time retracted state where the sheets are pushed against the sheet contact section so that the floating restricting member is retracted, and in the sheet-ejecting time retracted state where, when the sheets are to be removed, the sheet is pushed against the sheet contact section from below so that the floating restricting member is retracted.

  • Publication number: 20150169288
    Abstract: It is difficult to assign a unified index to log data accumulated and managed at individual systems with, for example, different installation ranges and times, a compliance standard, and vendors. Accordingly, it is burdensome to trace a flow of data and operations from the accumulated log data. Furthermore, if granularity of data which are output to logs differs, there is a possibility that data which can hardly be understood or are unnecessary depending on a user might be included even if all the logs are presented to the user. A log is linked to a sequence across nodes and systems by means of a combination of partial link information. Information is presented according to granularity based on the user's view, for example, on a transmitted and received data basis, application data basis, and inter-system data basis by referring to, for example, application data definition information and system configuration information.
