    摘要: According to the invention, a power supply for an image sensing device is obtained from a printer to prevent consumption of the battery. When the image sensing device is connected to the printer, a power management unit checks if electric power can be supplied from the printer. When electric power can be supplied from the printer, the power management unit switches the power supply from the battery to a power supply receiving/supplying unit that receives electric power from the printer. In this case, if the remaining capacity on the battery is small, the battery is charged by electric power from the printer. Also, the luminance of a display unit is increased, or the operation frequency of a control unit is raised. On the other hand, when electric power cannot be supplied from the printer, the power management unit switches the power supply to the battery. In this case, the power management unit reduces consumption power by decreasing the luminance of the display unit or reducing the operation frequency of the control unit.

    摘要: In a system to which a plurality of devices are connected, each device has heretofore required a connector for an AC adapter and a connector for a signal line. Further, in order to arrange it so that the amount of power supplied to the overall system will not exceed a limit value, it has been required to adjust the amount of power during system use by turning the power source of each device on or off. According to the present invention, a signal line for data transfer and a power line for supply of power in a system connecting a plurality of devices are consolidated in a single cable to make it possible to connect both lines to one connector of each device. The power controller of a certain device acquires the properties of a plurality of devices connected to this device, decides the optimum power distribution and controls the power controllers of each of the other devices.
