Abstract

Disclosed is a detached touch pad allowing for remote programming of a touch screen User Interface (UI) contained on an electrophotographic printing machine. The Light Emitting Diode (LED) array used on the Cathode Ray Tube (CRT) of the UI is duplicated on the touch pad with electrical signals connected in parallel with the UI. For reference, the UI possesses the same log map, only transparent, to help prompt an operator of the touch pad and help guide selection of the required programming available on the UI. The printing machine recognizes a beam interrupting combination on either the UI or the touch pad as a programming input.

DUAL TOUCH SCREEN USER INTERFACE

Disclosed is a detached touch pad allowing for remote programming of a touch screen User Interface (UI) contained on an electrophotographic printing machine. The Light Emitting Diode (LED) array used on the Cathode Ray Tube (CRT) of the UI is duplicated on the touch pad with electrical signals connected in parallel with the UI. For reference, the UI possesses the same log map, only transparent, to help prompt an operator of the touch pad and help guide selection of the required programming available on the UI. The printing machine recognizes a beam interrupting combination on either the UI or the touch pad as a programming input.

The remote touch pad further comprises a flat, panel-type housing having a suitable electrical socket and an LED transmitterh-eceiver printed circuit board, a bezel with key pad, an attached map, and suitable hardware required to hold the assembly together. An interconnecting cable connects the remote touch pad to the UI.

The disclosed touch pad construction and design for functionality eliminates the need for a duplicate UI.
