<p>PROBLEM TO BE SOLVED: To always keep the distance between an operator and a display constant and to prevent the deterioration of eyesight of the operator by automatically measuring the distance between the operator and the display and moving back and forth the position of the display. SOLUTION: An information processing main body has a display containing an optical sensor 2 and mounted on its front face and also includes a control part 3, a drive part which actuates a motor 4, a target value input part 1 which contains a target value setting keyboard on its front face against an operator, and a driving belt at its upper part respectively. The target value inputted from the part 1 is stored in the part 3. The sensor 2 measures the distance between the operator and the display and inputs this measurement result to the part 3. The part 3 compares the target value with the measured value, drives the motor 4 so as to minimize the difference between the target and measured value and actuates the driving belt where a display device is mounted to move the display back and forth. Thus, the display is always placed at the position optimum to the operator.</p> |
