An electronic device, which can charge a battery selected from a plurality of batteries and can drive the battery as a power feeding source, includes a control unit and a display unit. When a remaining power of a second battery that does not correspond to a first battery selected as a battery to be charged or the power feeding source among the plurality of batteries is higher than or equal to a predetermined threshold value, the control unit causes the display unit to display a remaining power of the first battery from among the remaining power of the first battery and the remaining power of the second battery, and when the remaining power of the second battery is lower than the threshold value, the control unit causes the display unit to display the remaining power of the first battery and the remaining power of the second battery.

Electronic device, battery condition display method, and printing apparatus

In a scanner, a medium transport apparatus includes an apparatus main body including a medium transport path from a supply unit, which supplies a medium, to a discharge unit, which discharges the medium, a switcher that switches an attitude of the apparatus main body with respect to a mounting surface on which the apparatus main body is mounted, and a controller that, when the attitude of the apparatus main body with respect to the mounting surface is switched, performs control in accordance with the attitude after the switching.

Medium transport apparatus and image reading apparatus

If data, which is irrelevant to recording data, is stored in a lower address of head word data of the run length compressed recording data stored in a receiving buffer unit, the irrelevant byte data of the lower address of the word data including the head byte data is nullified by masking to be developed by a decode circuit. Otherwise, in regard to a bitmap area of a local memory which is a DMA transfer destination, transfer addresses are individually set by a development processing controller in a DECU per one word of the developed recording data stored in the line buffer in order that data of one line is arranged and stored in a vertical direction, or data of one line is stored in imageand imagein turn. Otherwise, in regard to the development processing controller, when the recording data developed by the decode circuit is stored in the line buffer, it is stored from a first byte in a state where a 0-th byte of the line buffer is vacant.

Data transferring apparatus for transferring liquid ejection data and a liquid ejecting apparatus

Compressed recording data is DMA-transferred to a receiving buffer unit via a system bus one word each. It is DMA-transferred from the receiving buffer unit to a DECU via the system bus. It is developed based on hardware by a decode circuit in the DECU, and stored in a line buffer. It is DMA-transferred to a local memory via a local bus when it reaches predetermined bytes. The recording data stored in the local memory is DMA-transferred to the DECU via the local bus, DMA-transferred to a head controlling unit and DMA-transferred to a recording head.
