发明名称 POSITIONAL INFORMATION INPUT DEVICE FOR DISPLAY SCREEN
摘要 <p>PURPOSE:To arrange a display on a position apart from an operator by providing the device with a positional information input operation part, an image signalizing means for outputting an operating state at the positional information input operation part as an image signal, and an image signal synthesizing means. CONSTITUTION:The device is constituted of the positional information input operation part 2, a camera (image signalizing means) 3, the image signal synthe sizing part (image signal synthesizing means) 4, and the operation part 2 is provided with a panel electrode and a control circuit for transferring generated positional information to a personal computer 6. While observing the synthesized image of an image displayed on a display 5 and an operator's finger image or the like on the operation face of the panel electrode, an operator determines the depressing position of the panel electrode. The positional information of the depressing point of the panel electrode is transferred from the operation part 2 to the personal computer 6. Consequently, the display 5 displaying an image and the positional information input operation part 2 can be separatively used and the display 5 can be set up on the position separated from the operator inputting the positional information.</p>
