  • Patent number: 10040647
    Abstract: When a paper feeding ray is set, an arm of a one-armed pinion makes a contact with an abutting member formed in a main unit to which the paper feeding tray is attached. When the paper feeding tray is pushed in, the arm is pushed by the abutting member, the one-armed pinion rotates as the rack member moves, and the one-armed pinion moves in a direction into the paper feeding tray. When a spring is stretched, a bottom plate push-up member rotates up on its rotation center and rises by a predetermined angle to press a bundle of stacked paper sheets against a feed roller, so that the paper sheets can be fed.

  • Patent number: 9979643
    Abstract: A communication apparatus includes a first storage unit, a second storage, and a first registrator. The first storage stores at least a destination address representing an IPv6 address that is a destination of a packet and a next hop address representing an IPv6 address of a next hop representing the next destination to which the packet is transferred in association with each other. The second storage stores an IPv6 address of a default router to which the packet is transferred when it is not possible to determine the next hop address by using the first storage. When a second RA packet representing an RA packet other than first RA packets representing a RA packet for 6LowPAN is received, the first registrator registers an IPv6 address from which the second RA packet has been transmitted as an IPv6 address of the default router.
