Optical sensor switch system for a scanner
 An optical sensor switch system is used to effect a selection function of a scanner. The depressed switch for a selected function changes the light intensity incident on the pixels of a light sensitive panel in two steps. This change in light intensity activates the operation of the particular function. The change in light intensity is effected by shuttering the light from a source to the pixels. The pixels of the panel are divided into different sections, each designated to a particular function for the scanner.
