Preset counter apparatus for copying machines and the like

Image Number 3 for United States Patent #4491827.

The present invention provides a preset counter apparatus for a copying machine wherein input keys are capable of independently controlling the numerical value of the number of copies to be made and displayed. Thus, an operator can activate one key to change the digit positions of units and another key to change the digit position of tens. The control of the number of copies to be made is specifically designed to facilitate operator use and to avoid operator errors. Simultaneous activation of more than one key prevents any change in any values in both the units and tens positions.
