<p>PURPOSE:To easily ensure the drawing ability equivalent to the colors which are sprayed by providing an input device which produces the input data from the electromo tive force of different levels which are generated based on the range of irradiation and the luminous intensity of the light irradiating a photodetecting plane containing a photoelectric transducer. CONSTITUTION:A light emitting device 11 emitting the light which is diffused at a fixed angle with operation of a control button 11a, and a photodetecting plane 12 containing many minute light receiving elements distributed evenly on the plane are provided. When the plane 12 is irradiated by the light, the element existing at the irradiating position performs the photoelectric transducing action in response to the luminous intensity and outputs an analog signal. A controller 13 receives the analog signal and converts it into a digital signal to calculate the coordinates showing the irradiated position of the maximum luminous intensity, the contact coordinates between the irradiation range and a circumscribed quadrilateral, etc. Then the controller 13 specifies a range of irradiation and sends the basic data to a computer for calculation of the brush thickness, the color gradation, the angle of irradiation, or the distance from an airbrush, etc. Thus it is possible to obtain an input device which has a func tion equivalent to an airbrush which sprays the colors with high working efficiency and with a simple operation.</p> |
