  • Patent number: 10543995
    Abstract: A sheet conveying apparatus includes a rotation member unit, a supporting shaft, and a moving shaft to detach the rotation member unit supported by the supporting shaft and the moving shaft. The rotation member unit includes a conveyance rotation member to convey a sheet, and a holding member including an engaging portion to engage with an engaged portion provided to a sheet conveying apparatus main body in a direction perpendicular to the supporting shaft axial direction. The supporting shaft supports one end side of the rotation member unit in the axial direction and the moving shaft supports another end side of the rotation member unit in the axial direction and moves in the axial direction. When the engaging portion engages with the engaged portion when the rotation member unit is not supported by the supporting shaft and the moving shaft, the rotation member unit is held by the engaged portion.

  • Patent number: 10486927
    Abstract: A sheet feeding apparatus includes a sheet presence/absence detection sensor configured to detect presence or absence of a sheet on a stacking device, a sheet surface detection sensor configured to detect that a stacking tray is raised to enable a sheet to be fed, a separation cam, and a control unit. The control unit is configured to determine that the mounting state of a feeding holder to a holder support unit is defective when the sheet surface detection sensor detects that the sheet can be fed when the sheet presence/absence detection sensor detects absence of a sheet before sheet feeding processing by a pickup roller.

The noise reducer includes a common-mode choke coil and a smoothing capacitor. The common-mode choke coil includes a loop-shaped core, a first winding wound around the core, a second winding wound around the core, the second winding being spaced apart from and opposed to the first winding, and a loop-shaped conductor that covers the core while extending over the first winding and the second winding. The core includes an exposed portion that is not covered with the conductor. Parts of the conductor that are opposed to each other between the first winding and the second winding are spaced apart from each other.

  • Patent number: 10365871
    Abstract: An information terminal apparatus includes an associating processor, a process execution circuitry, a base detector, and a controller. The associating processor associates each of connection bases with both base identification information and limitation information regarding a data process. The base identification information identifies corresponding one of the connection bases. The process execution circuitry causes an information processing apparatus to execute the data process. The information processing apparatus is connected to at least one of the connection bases. The base detector detects that any of the connection bases becomes a connectable base. The controller causes, when the connectable base is detected by the base detector, the information processing apparatus connected to the connectable base to perform the data process based on the limitation information.

  • Patent number: 9126789
    Abstract: The present invention provides an image forming apparatus that can facilitate a replacement of a sheet feeding portion. When a detecting portion detects that a sheet feeding cassette is mounted, a controller controls a driving portion in such a manner as to lift a sheet supporting plate for the mounted sheet feeding cassette. When the detecting portion detects that a sheet feeding cassette is mounted, the controller controls a driving portion in such a manner as not to lift a sheet supporting plate for the mounted sheet feeding cassette in the case where it is determined that a sheet feeding cassette nearest a feeding roller of the mounted sheet feeding cassette is drawn or detached.

  • Patent number: 8727339
    Abstract: When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.
