Abstract
PURPOSE:To enable to determine the degree of floor dirt, by detecting the light amount of reflection on floor and by the measurements independent on the visual feeling only. CONSTITUTION:The light source 2 and the light amount detection element 4 are placed on the upper surface of internal the dark box 1 so that the light from the light source 2 does not directly emit the element 4. The light source 3 is fitted under the dark box and the light from the light source 3 does not directly emit the element 4 by means of the light shield plate 5. The internal surface of the lower cover 6 constitutes the standard white surface 7 for calibration. Inside the upper cover 9, the power supply 10, indicating meter 11, and circuits 12, 13, 14 for measurement, constant voltage and calibration, and on the cover 9, the switches 15, 16, 17 for power supply, measurement of light amount reflected from the mirror surface, and acattered reflection light amount measurement, and the mirror angle reflection light amount measurement calibration dial 18, and calitration dial for scattered reflection light amount 19 are fitted so that they can easily be operated. Thus, the measurements of scattered reflection light amount and mirror surface reflection light amount can be obtained as the relative values taking the standard white surface as the reference value respectively.
