<P>PROBLEM TO BE SOLVED: To provide a reflector device which form the image of a television screen at an optimum position where the elevation angle of sight line is close to 70°, and to provide a dimension calculation method for implementing the same. <P>SOLUTION: The elevation angle of sight line for watching the image of a television screen formed by a reflector device can be set to less than 90°, by locating a reflector 1 above a reflector 2. Furthermore, a dimension calculation method for optimizing the dimensions of the reflector device and the elevation angle of sight line in correspondence with the size of the television or the change in position thereof is established. When using a reflector device configured by using that method, a television viewer can watch the image of a television screen in a comfortable posture with natural sight line. <P>COPYRIGHT: (C)2013,JPO&INPIT |
