Abstract: An optical scanner and an optical scanning control method. The optical scanner includes a light source configured to emit light, a light deflector configured to deflect the light emitted from the light source to scan a scanning area two-dimensionally in a main scanning direction and a sub-scanning direction, and a photodetector configured to detect scanning light deflected by the light deflector to perform scanning on a detection field included in the scanning area. In the scanning area, a detection scanning area is formed by the scanning light so as to include an end of the detection field, and a size of the detection scanning area is changed. The optical scanning control method includes forming a detection scanning area by scanning light so as to include an end of a detection field included in a scanning area that is two-dimensionally scanned, and changing a size of the detection scanning area.

Abstract: A system has information processing devices and a server which controls information processing executed by the devices. One of the devices includes a querying part to transmit a query to the server whether the device is permitted to execute the information processing, a notifying part to notify the server of location information indicating a location of the device, and an executing part to execute the information processing in response to an instruction from the server. The server includes a receiving part to receive the query from the device, an identifying part to identify an area in which the device exists according to the information notified by the device which has transmitted the query, and an instructing part to instruct the device which has transmitted the query to execute the information processing based on how many other devices are executing the information processing in the area.

Abstract: An image processing apparatus includes: an image reading unit that reads an image; an input unit that inputs data acquired by reading an image that is read by the image reading unit into a first storage unit; a read-out unit that reads out and transmits the data stored in the first storage unit; an image forming unit that forms an image on a recording medium by using the transmitted data; a measurement unit that measures time relating to the transmission of the data; and a storage control unit that stores a maximum value of the time measured by the measurement unit into a second storage unit.

Abstract: A serial ATA interface interfaces an ASIC with a HDD. A transfer start monitoring unit monitors start of data transfer between the ASIC and the HDD and a transfer completion monitoring unit monitors completion of the data transfer. A power management control unit controls power consumption of the ASIC and the HDD based on monitoring results obtained from the transfer start monitoring unit and the transfer completion monitoring unit.

Abstract: An SD card interface, which is an interface for a detachable SD card requiring an access in sector units (a specific size), has a function to initialize an SD controller, a function to initialize an SD card, and a function to acquire status of the SD card.

Abstract: An image forming system includes a plurality of image forming apparatuses which are connected to each other via a communication line. Each of the image forming apparatuses includes an image reader that reads an image of an original document as image data; an image data storage that stores the image data; an image forming unit that forms an image onto a sheet of paper from the image data; and a communication unit that transmits and receives any one of the image data and control data for controlling an image forming operation. At least one of the image forming apparatuses includes an output timing controller that controls the plurality of image forming apparatuses so that start time of an image forming operation are different among the plurality of image forming apparatuses.
