Abstract
A stack height sensor for stacked sheet members includes a switch having an actuator arm positioned adjacent to top edge of the stack at a predetermined level. A flexible 'flogger' or 'scuffer' element is moved along a path which first contacts the top surface of the sheet members, and then slides off the stack edge in the direction of the switch actuator arm. The switch actuator arm is adjusted such that the deflected path of the flexible flogger or scuffer element intercepts the switch for stack heights less than the predetermined value and 'ski jumps' the switch actuator arm for stack heights greater than the predetermined height. The flogger or scuffer elements can be mounted on the disk inverter of a photocopier output section, and the switch output be used to control the position of the stack elevator mechanism. Alternatively a separate hub synchronized for rotation with the disk inverter, can be used to mount the flogger or scuffer elements.
