A
glasses type display that is connected to an information communication terminal via a wire line or a
wireless line, in which the operation by the user is made simple by preventing error operation and the
power consumption is decreased by not consuming the unnecessary power, is provided. The
glasses type display provides lenses, a main frame, side frames, a
microphone, a speaker(s), open and
closed state detecting sensors, wearing state detecting sensors. When the user opened the side frames, the open and
closed state detecting sensors react, and the wearing state detecting sensors become the on state. When the user put on the
glasses type display, the lenses automatically become the on state by that the wearing state detecting sensors detected the wearing state. And when the reaction from a part of the wearing state detecting sensors was turned off, caused by some vibration, the lenses are not immediately turned off. Therefore, an error operation is avoided. When the side frames were closed, the lenses were turned off automatically by the operation of the open and
closed state detecting sensors. Therefore, the unnecessary
power consumption is avoided.
