  • Patent number: 9778887
    Abstract: A printer switches between and uses plural communication units according to the operating mode, can switch the operating mode appropriately to the operating conditions, and can improve power conservation. The printer has a network control unit with a first communication unit configured to communicate in a first operating mode; and a main control unit having a second communication unit configured to communicate in a second operating mode. The main control unit limits the power supply to the first communication unit in the second operating mode; and the second communication unit determines whether or not to go to the first operating mode based on content of data received in the second operating mode.

  • Patent number: 9643440
    Abstract: Efficient power conservation is enabled using a configuration having multiple processors. A printing device has a first processor unit that runs a program stored in a first memory, and a second processor unit that runs a program stored in a second memory, and has operating modes including a normal mode in which the first processor unit and the second processor unit operate according to a normal clock, and a first power conservation mode in which, after going to a state enabling the first processor unit to execute some processes of the second processor unit, the first processor unit operates according to the normal clock, and the second processor operates according to a slow clock having an operating frequency lower than the normal clock.

  • Patent number: 7986289
    Abstract: An object of the invention is to repair a drain signal line easily. Each region enclosed by two gate signal lines adjacent to each other and two drain signal lines adjacent to each other that are formed on the liquid-crystal-side surface of one of transparent substrates that are opposed to each other with a liquid crystal interposed in between is made a pixel region. Each pixel region is provided with a switching element that is driven being supplied with a scanning signal from one of the two gate signal lines and a pixel electrode that is supplied, via the switching element, with a video signal from one of the two drain signal lines. A repair conductive layer is formed so as to be contained in each drain signal line when viewed perpendicularly with an insulating film interposed in between.
