Abstract

In a full featured electroreprographic machine, it is known to utilize some form of editing capability to alter the image reproduced on the copy sheet. In many machines an editing pad is used to accomplish the input of editing coordinates. Generally, the editing pads utilize a special stylus or an acoustic measurement system to determine the coordinate information.

In a full featured electroreprographic machine, it is known to utilize some form of editing capability to alter the image reproduced on the copy sheet. In many machines an editing pad is used to accomplish the input of editing coordinates. Generally, the editing pads utilize a special stylus or an acoustic measurement system to determine the coordinate information.

Accordingly, the present disclosure is directed at an editing pad which would be comprised of a two-dimensional array of force sensitive resistors. The force sensitive resistors can be used as tactile sensors because the resistance of the force sensitive resistor is inversely proportional to the force applied thereto. Thus, the change in resistance would not only indicate the X-Y coordinate of the user's finger or editing probe, but the magnitude of the change would also provide a third component based upon the force applied by the user. The information provided by the force (resistance) component could enable additional operations to be performed by the editing pad. For example, the amount of force may be used as an indication of the thickness of a border to be placed around the edit region, as an indication of the contrast level of the edit region, or possibly as an indication of colorization effects for...
