摘要： PROBLEM TO BE SOLVED: To provide a small portable routing information display system, which can audibly acquire accurate information on the route to a destination without troubling anyone else only by inputting a phone number.
SOLUTION: This portable routing information display system is designed so that first it finds its own current position, memorizes its target position according to the input phone number, and then computes the target position applicable to the input phone number. Additionally, information on the route to the target position associated with the phone number input from the obtained current position will be computed based on the memorized map data, while being output as voice or speech.

摘要： PROBLEM TO BE SOLVED: To provide a display device capable of securing sufficiently enough display luminance even when a light source having a small calorific value is used as a back light device, reducing its cost because it is unnecessary to prepare switching elements for driving liquid crystal correspondingly to respective pixels and instantaneously displaying a clear information picture because pictures can be quickly switched. SOLUTION: This display device is provided with a combiner 4 for changing the optical path of picture display light rays L1 projected from a projecting device so as to lead the light rays L1 to the visual field of an observer A and transmitting light rays radiated from an observer's front visual field. The projecting device has a transmission type monochromatic simple matrix liquid crystal display 11 of which liquid crystal operation mode is a bistable twist nematic(BTN) mode, a back light device 12 capable of changing the light emitting wavelength peak of irradiating light from the display 11 and a means 13 capable of synchronizing the picture display timing of the display 11 with light emission timing based upon the light emitting wavelength peak outputted from the device 12.

摘要： PURPOSE: To enhance working efficiency, to secure safety, and to reduce the fatigue of the eyes by preventing the component members and displayed image of a display device from obstructing the front viewing field of the observer. CONSTITUTION: This head-mounted display device has an image display part 2 and a head-mounted holding part 3 holding the display part 2. The display unit 13 of the display part 2 has a housing 21 secured to the front of the holding part 3, and the housing 21 has a display-system storing part 21a projecting forward from the holding part 3 and a lens-system stoning part 21b extending downward from the front end of the storing part 21a. When the visual line of the observer points to the front, the lens-system storing part 21b is in a position outside the range of the viewing field, whereas when the visual line is pointed upwards of the front (arrow M), the lens-system storing part 21b is located in a position within the range of the viewing field. Thus, when the visual line of the observer points to the front, the image on the display member 2 is out of the range of the viewing field; when the visual line is pointed to other than the front, e.g., upward, the image is within the range of the viewing field; also, the component members of the head-mounted display device 1 are out of the range of the viewing field when the visual line of the observer points to the front.

摘要： PURPOSE: To confirm information in real time and improve operation efficiency by displaying information selected out of piled-up article information as a display image within the visual field range of a person who puts on a head mount type display device. CONSTITUTION: Article discrimination information and article information on a sale quantity, etc., are inputted to each terminal 3 from a bar code stuck on an article through a bar code reader and the inputted article information is stored by a host computer 4. The host computer 4 selects an object to be displayed by the head mount type display device 2 out of the stored article information. The selected article information is transmitted to the head mount type display device 2 from the host computer 4 through a communication interface 5. For example, a worker W of a warehouse who supplies articles to a supermarket puts on the head mount type display device 2 and the selected article information is displayed as a display image within the visual field range of the worker W.

摘要： PROBLEM TO BE SOLVED: To provide a display device which is small-sized and lightweight and which can form a clear enlarged virtual image. SOLUTION: An optical system 40 which forms an enlarged virtual image of a display image formed by a reflection type display element 12 having an image display screen 12a has a prism 40 molded out of a synthetic resin material. The prism 40 is so joined with the display element 12 so that the light emitted by a light source unit embedded in the prism 40 passes through the prism 40 and then enters the prism 40 again after being reflected by the image display screen 12a. The light entering the prism 40 again is guided to the eye of an observer after having its optical path changed by the prism 40, so that the enlarged virtual image is formed farther away from the display element 12 in the view point of the observer.
