Abstract
A reproduction apparatus having a logic and control unit (LCU) and selectable copy sheet supply units includes a mechanism for determining the sheet weight of copy sheets to be handled therein. The mechanism includes a platform for supporting one such sheet on a desired surface, and a proximity sensor that is connected to the LCU and mounted at a predetermined height above the sheet supporting surface. The mechanism also includes a variable voltage sheet buckling device for creating a buckle in the supported sheet sufficient to actuate the proximity sensor. Means are provided in the logic and control unit for reading the voltage level of the sheet buckling device at the actuation of the sensor, and for correspondingly reading from a truth table a predetermined sheet weight for the read voltage level.
