APPARATUS FOR DISCRIMINATING BETWEEN PAPER SEPARATOR SHEETS AND EMULSION COVERED COMPUTER TO PRESS PRINTING PLATES |
摘要 |
<p>An apparatus for discrimination between a first (308) and a second surface (304) type based on reflectivity has a light source (416) that illuminates on a media surface. A photosensor (420) receives and measures the reflection value from the surface. A first gain element adjusts a voltage from the photosensor and a second gain element adjusts a current measurement supplied to the light source. A subtractor (530) for subtracting the first adjusted voltage (534) and the adjusted measurement (538) are subtracted to provide an output value close to zero with respect to the second surface and near a maximum with respect to the first surface. The adjusted reflection value and a threshold reference value (428) are compared (124) and indicates whether the first surface or the second surface is present.</p> |
