<p>PROBLEM TO BE SOLVED: To provide an instruction inputting device by a remote operation which can be substituted for a mouse. SOLUTION: This device is provided with a user instructor 5 for which a recursive reflector 22 is attached to an infrared remote controller 21 for instructing an operation mode by a remote operation, and a control unit 4 equipped with a light transmitting and receiving part having a light emitting element and a light receiving element which receives a reflected light from the recursive reflector 22, a receiving part which receives an instruction from the infrared remote controller 21, and a presenting part which presents the received operation mode. Then, the moving amount of a point mark on the display screen of a monitor device 2 is made correspond to the changing amount of the incident angle of the reflected light from the recursive reflector 22 to the light receiving element, and the menu selection and screen operation of a personal computer 1 are operated.</p> |
