Abstract: An information processing apparatus includes: an electric-power generating unit that generates electric power; an electric storage unit that stores electric power generated by the electric-power generating unit; and a control unit that, while in an energy-saving waiting mode in which the apparatus is in a waiting state to wait for an input of a job and in which electric power is supplied from the electric storage unit and, when the input job is for a predetermined low operation that has low power consumption, causes electric power to be supplied from the electric storage unit only to a section that is used for the low operation and that, when the input job is a job other than the job of the low operation, selects power being supplied from a commercial power source, and executes the job by using a section to which the selected electric power is supplied.

Abstract: An image processing apparatus included in a system including another image processing apparatus, and configured to transition to a first and a second electric power saving mode when functioning as a main apparatus and a slave apparatus, respectively, in the system where the second electric power saving mode is lower than that of the first electric power saving mode, includes a function determining unit which determines whether the image processing apparatus is to function as the main apparatus or the slave apparatus based on a status of the other image processing apparatus which is obtained when the image processing apparatus is performing a job; and an instruction sending unit which sends an instruction to have the other image processing apparatus function as the slave apparatus or the main apparatus when the image processing apparatus is determined to function as the main apparatus or the slave apparatus, respectively.

Abstract: In an embodiment, provided is a control device that operates: in a second mode where electric power to each of a processing unit and a second storage unit is stopped and is supplied to a first storage unit; and in a first mode where first control information controlling a state of the processing unit is stored in the second storage unit and electric power to each of the processing unit, and the first and second storage unit is stopped. When shifted from the first to second mode, the power supply control unit starts supply of electric power to each of the processing unit and the first storage unit. If the processing unit has been made to be in an operable first state, the processing unit creates and stores second control information in the first storage unit. Then, the power supply control unit stops electric power to the processing unit.

Abstract: An image reading apparatus includes a reading image unit that reads an image data of a document; a memory that writes the image data obtained by the reading image unit in a space region of the memory; a memory managing unit that determines whether the space region larger than a predetermined memory size of the memory exists; and a reading operation control unit that manages reading image operation and interruption of the reading image unit for a reading section of the document having a unit data size corresponding to an amount of the image data being writable in the predetermined memory size; wherein the memory management determines whether or not the space region larger than the predetermined memory size exists in the memory.

Abstract: An image forming apparatus includes an image forming unit configured to form an image on a medium; a control unit configured to control the image forming unit; a power supply unit configured to supply power from a commercial power source; a power generating unit configured to generate power that is separate from the power supplied from the commercial power source; and a secondary battery charged by the power generated by the power generating unit. The control unit switches a power source between the power supply unit and the secondary battery, the power source supplying power to at least the control unit.
