The two areas switch between a folded state facing the areas each other and a two-page spread state not facing the areas each other. When an induced current is not detected in the coils of the two areas in the continuous reception state in which the induced current of the coils can be detected, the determination portion determines that the detection portion is in the two-page spread state. When the induced current is detected in the coils of the two areas in the continuous reception state, the determination portion determines that the detection portion is in the folded state, and the switching portion switches the state of the detection portion from a normal state to a power saving state.

  • Patent number: 9671910
    Abstract: An electronic device may include a first controller associated with some channels of a digitizer having channels configured to receive a signal from a stylus, and with each channel having a direction. A second controller may be associated with channels of the digitizer not associated with the first controller. The first controller may scan for the signal at each channel associated with the first controller, and based on acquisition of the signal at a given channel associated with the first controller, calculate a property of the signal. The first controller may send the calculated property and the direction of the given channel to the second controller. The first controller and the second controller may scan for the signal at each channel having the direction of the given channel, at acquisition intervals based upon the calculated property.

  • Patent number: 9645666
    Abstract: A display device equipped with a touch panel includes a touch panel unit, a touch panel control unit, a pen incline information acquiring unit, a coordinate correction unit, and a display panel unit. The touch panel control unit detects a touch upon a touch panel surface, and acquires touch point coordinate information which is information for specifying a location which is touched on the touch panel surface. The pen incline information acquiring unit acquires pen or input member incline information, which is information relating to an angle which is formed by the touch pen and the touch panel surface when the touch pen and the touch panel face are in contact. The coordinate correction unit corrects, on the basis of the pen incline information, the touch point coordinate information when the line is drawn with the touch pen or input member upon the touch panel screen.
