A power supply device installed in an electronic apparatus includes a first power supply outputting power upon a plug being connected to a system power supply, a second power supply outputting power upon receiving of a power supply control signal, a third power supply outputting power from a battery, a controller operating using the power from the second power supply and configured to control the electronic apparatus, a flip-flop configured to operate using the power from the third power supply and configured to store, upon activating the electronic apparatus, first logic data or upon shutting down the electronic apparatus, second logic data, and a power supply control switch operating using the power from the first power supply, to output the power supply control signal to the second power supply, in response to activating the electronic apparatus or in response to storing the first logic data in the flip-flop.

Power supply device configured to automatically restore power after recovery from a power failure, image forming apparatus, and control method

A recording apparatus includes a head unit, which includes a driver, and a recording data transmitter that transfers recording data to the head unit via a signal line. The recording apparatus further includes a switching unit in the head unit that switches a driving signal applied to the driver between conductive and nonconductive states based on the transferred recording data, a partition signal output unit in the recording data transmitter that outputs a partition signal that partitions a data signal of the recording data to the head unit in response to switching by the switching unit, and a data selector in the head unit that selects data to be discarded from the transferred recording data based on the partition signal.

Recording apparatus and recording apparatus control method

An information processing apparatus includes a receiver configured to receive a packet via a communication line, an operating processor configured to suspend an operation thereof when the information processing apparatus is in an energy saving mode, a first storage configured to store the packet received by the receiver, a determining unit including a table in which different operations of the operating processor are recorded in association with different patterns of packets and configured to determine whether to restart the operating processor when the information processing apparatus is in the energy saving mode based on a pattern of the packet stored in the first storage and the patterns of the packets in association with the operations of the operating processor recorded in the table, and a power manager configured to supply power to the operating processor based on a result determined by the determining unit to restart the operating processor.

Information processing apparatus and method for saving energy in an image processing apparatus

An information processing apparatus includes a receiving part receiving a packet from a communication line; an arithmetic processing part configured to stop an operation in an energy conservation mode, a filter part configured to allow a response required packet to pass through the filter part; a packet retaining part retaining the packet passing over the filter part; and a power source administrating part activating the arithmetic processing part by supplying electric power when the packet is received by the receiving part, wherein if the packet retaining part retains an incomplete packet at a time of activating the arithmetic processing part, the arithmetic processing part generates a packet information piece associating the incomplete packet and a corresponding complete packet as a list and stores the packet information piece to a list storing part.

Information processing apparatus, information processing method and information processing program

A discharge energy recovery device to recover discharge energy discharged from a piezoelectric element when the piezoelectric element is driven includes a drive voltage generator to generate a voltage to drive the piezoelectric element; a discharge voltage monitoring unit to monitor a discharge voltage discharged from the piezoelectric element when the piezoelectric element is driven by the drive voltage generator; a plurality of charge accumulating devices to accumulate a charge corresponding to a voltage monitored by the discharged voltage discharge voltage monitoring unit; and a selection unit to select one or more charge accumulating devices from the plurality of charge accumulating devices having capacity sufficient to enable accumulation of the charge corresponding to the voltage monitored by the discharge voltage monitoring unit.
