  • Publication number: 20200307936
    Abstract: A sheet stacking apparatus includes an ejector, a stacker, a wall, and an upper surface detector. The ejector ejects a sheet, and the stacker stacks the sheet ejected from the ejector. The wall contacts a trailing end of the sheet ejected from the ejector in an ejection direction to align the sheet. The upper surface detector detects an upper surface on a trailing end side of the sheet stacked on the stacker in the ejection direction. When the sheet moves toward the wall, the upper surface detector moves from a home position in which the upper surface detector detects the upper surface of the sheet to a retracted position in which the upper surface detector does not contact the sheet moving toward the wall.

  • Publication number: 20200120751
    Abstract: A User Equipment (UE) transmits a registration request message to an AMF in a registration procedure to a core network, the registration request message including information indicating a request for transmission of LADN information, receives the LADN information from the AMF, performs a PDU session establishment procedure initiated by the UE to establish a first PDU session with a DN different from the LADN, and performs the PDU session establishment procedure initiated by a network to establish a second PDU session with the LADN in a case that the UE moves to an area connectable to the LADN. This provides a control method that should be performed by each apparatus constituting a 5GS for the UE to establish the session to the LADN, and a control method for allowing only the UE connectable to the LADN to establish the session to the LADN.
