<p>PURPOSE:To provide the cathode-ray tube (CRT) suitable for a display device for digitizing input directly formed with a coordinate position detector of an electromag netic guiding system capable of high-accuracy digitizing input and made thin in size and light in weight on the surface of the tube. CONSTITUTION:A projecting part along the peripheral face of the CRT is formed by providing a notched part at one part, and pin frames planting plural pins for sensor line layout are arranged while being respectively faced each other in X axis and Y axis directions on the inner peripheral face of the tube surface at the projecting part. Then, sensor lines provided with insulated cover layers are laid with prescribed patterns in the X axis Y axis directions on the surface of the tube while being successively hung and folded at the pins for sensor line layout, and the respective terminal parts of the sensor lines laid in the X axis and Y axis directions are led out to the outer periphery of the surface of the CRT. Further, a transparent bent insulated protection board is fixed by adhesive from the surface of sensor lines to the projecting part, and the sensor lines are fixed inside a space formed by the surface of the CRT, the projecting part and the transparent bent insulated projection board.</p> |
