Abstract:
1. A processing apparatus comprising: a plurality of processing units each of which is configured to operate in response to being supplied with electric power; a first detector configured to detect, in response to being supplied with electric power, an object entering a first detection area; a second detector configured to detect, in response to being supplied with electric power, an object entering a second detection area narrower than the first detection area; and a first controller configured to control power supply to the plurality of processing units, the first detector, and the second detector, wherein: the first controller is configured to, at a start of a power-saving mode, stop supplying electric power to the second detector and at least one processing unit among the plurality of processing units and supply electric power to the first detector, the first controller is configured to, after the start of the power-saving mode, restart supplying electric power to the second detector in response to the first detector detecting an object entering the first detection area, and the first controller is configured to, in response to the second detector detecting an object entering the second detection area in the power-saving mode, restart supplying electric power to the at least one processing unit that has not been supplied with electric power so as to cancel the power-saving mode, wherein the plurality of processing units include: a third detector configured to detect, in response to being supplied with electric power, opening and closing of a pressing plate that presses a document positioned on a document scan table of the image scanning unit from above; and a fourth detector configured to detect, in response to being supplied with electric power, whether or not a document is positioned on a document feeder that feeds the document to the document scan table, wherein the first controller is configured to, at the start of the power-saving mode, stop supplying electric power to the second detector, the third detector, the fourth detector, the operation receiving unit, the image scanning unit, the image forming unit, and at least part of the second controller, and the first controller is configured to, after the start of the power-saving mode, the restart supplying electric power to the second detector, the third detector, and the fourth detector in response to the first detector detecting an object entering the first detection area.
