  • Publication number: 20130328965
    Abstract: A liquid discharging apparatus, which discharges liquid from a nozzle of a liquid discharging head on the basis of data, includes a controller and a member. When the controller is in a standby state where the liquid is not discharged from the nozzle on the basis of the data or after the controller has received a power OFF instruction, the controller performs a drawing operation in which the liquid is drawn to a side opposite to a discharge direction in which the liquid is discharged so as to at least form a space at a distal end portion of the nozzle. After the controller has performed the drawing operation, the member covers an opening of the nozzle.

  • Publication number: 20130278497
    Abstract: An attitude information detection unit detects the attitude of a wearer, and an arithmetic processing unit and a device position drive unit, which form an image area position adjustment mechanism, translate a liquid crystal display device that is a light modulating device relative to a light guide section in a plane parallel to a light incident surface of the light guide section based on a detection result from the attitude information detection unit, whereby the position of an image area can be so changed that an image moves in the direction opposite the direction in which the wearer moves. As a result, when the wearer moves, the image does not follow the motion of the wearer as if the image remained still, whereby the wearer who moves will have a reduced amount of unpleasant sensation resulting from the motion.
