摘要:
A method of controlling operations of a participating controlled device in a network that includes a control device and the participating controlled device, the method including: receiving operation limiting information from the participating controlled device, the operation limiting information including combinations of allowed operations from among a plurality of operations that the participating controlled device is capable of performing, and power consumption levels that are relative amounts of power consumption of the combinations of allowed operations; setting a power consumption level corresponding to the participating controlled device, from among the power consumption levels, based on information regarding time-based price and the operation limiting information; and controlling the operations of the participating controlled device based on the set power consumption level.
摘要:
A printing medium feeding cassette usable with an image forming apparatus includes a first casing including a guide member which extends along a sliding direction, and a plurality of coupling parts arranged in a central area of the guide member to be spaced from each other along the sliding direction, a second casing which forms a printing medium containing space in cooperation with the first casing to slide along the guide member, a stopper to reciprocate in a direction transverse to the sliding direction between a coupling position in which the stopper is coupled with any one of the plurality of coupling parts and a releasing position in which the stopper is released from the coupling part, and a releasing member which is coupled with the second casing to move in the sliding direction in connection with the second casing and is moved by an external force applied thereto in the sliding direction to allow the stopper to move to the releasing position from the coupling position.
