at least one processor communicatively connected to the at least one memory device of the first network device and configured by the first set of instructions to:
display at least some of a plurality of types of IPv6 addresses as available for user designation for registration in the DNS server;
receive a user instruction selecting, from the display of the at least some of the plurality of types of IPv6 addresses available for user designation for registration in the DNS server, a type of IPv6 address to be registered in the DNS server, wherein a user is permitted to select by the user instruction less than all of the plurality of types of IPv6 addresses;
determine whether or not a dynamic DNS function has been enabled;
determine at least one IPv6 address of the plurality of IPv6 addresses associated with the first network device, the at least one IPv6 address corresponding to the type selected in accordance with the user instruction; and
request, via the network, the DNS server to register a host name of the first network device and the determined at least one IPv6 address, at least in a state in which the dynamic DNS function has been enabled, and
wherein the second network device comprises:
at least one memory device that stores a second set of instructions; and
at least one processor communicatively connected to the at least one memory device of the second network device and configured by the second set of instructions to:
obtain at least a particular IPv6 address having been registered in the DNS server based on the host name of the first network device; and
transmit a packet to the particular IPv6 address.

BELT TRANSPORTING DEVICE AND IMAGE FORMING APPARATUS

Canon Kabushiki Kaisha, ...

1. A belt transporting device comprising:an endless belt configured to rotate;
a first stretching member configured to stretch the belt;
a second stretching member configured to stretch the belt; and
a belt adjusting unit configured to adjust movement of the belt with respect to a widthwise direction of the belt perpendicular to a movement direction of the belt by tilting the first stretching member with respect to the second stretching member,
wherein the belt-adjusting unit includes:
a first adjustment member provided at one end side of the first stretching member with respect to the widthwise direction, wherein the first adjustment member is rotatable relative to the first stretching member to change a position of an end portion of the first stretching member,
a second adjustment member provided at another end side of the first stretching member with respect to the widthwise direction, wherein the second adjustment member is rotatable relative to the first stretching member to change a position of another end portion of the first stretching member,
a first frictional surface configured to cause friction against the first adjustment member,
a second frictional surface configured to cause friction against the second adjustment member, and
an interlocking device configured to rotate the second adjustment member with respect to the second frictional surface according to a rotation of the first adjustment member with respect to the first frictional surface, in a case where the first adjustment member receives a force from the belt when the belt is shifted in the widthwise direction of the belt.

SHEET CONVEYING APPARATUS

Canon Kabushiki Kaisha, ...

1. A reading apparatus comprising:a document placement table on which a document is placeable;
a reading unit configured to read the document placed on the document placement table;
a first conveying unit configured to load a plurality of documents and to convey the loaded documents individually toward the reading unit, the first conveying unit being capable of moving to a first position located above the document placement table and a second position rotated from the first position; and
a second conveying unit configured to be capable of moving to a third position and a fourth position rotated from the third position, the third position being a position to which a conveyed document from the first conveying unit in the first position is conveyed,
wherein when the first conveying unit is in the second position, the conveyed document from the first conveying unit is conveyed to the reading unit without passing through the second conveying unit.
