Abstract
Abstract A control system for entering data into a copier controller relating to the parameters of an original to be copied, having a platen upon which the original is placed for exposure, comprising electrically sensitive membrane strips applied adjacent to the platen, said strips being formed with touch sensitive portions whereupon touching by an operator effects a signal indicative of the location of the touch, and means connecting the strips to the controller for transmitting the signals thereto, the signals being representative of document size. Also included is a special switch to convert the touch sensitive portions of the membrane strips into document editing functions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
In a copier having a controller and a platen upon which an original is placed for exposure, a control system for entering dimensional data into the controller, the control system comprising: a first electrically sensitive membrane strip disposed along one axis of the platen, a second electrically sensitive membrane strip disposed along another axis of the platen, the membrane strips being conterminous with the edges of the platen, said membrane strips being formed with touch sensitive portions such that touching by an operator effects a signal indicative of the location of the touch contact, means connecting said strips to the controller for transmitting said signals thereto as indicative of the dimension of the original along the effected edge thereof, and a third electrically sensitive membrane strip, said third electrically sensitive membrane strip electrically connected to the controller and including a conversion switch, activation of said conversion switch enabling the touching of said touch sensitive portions to selectively edit segments of the document related thereto.
Claim 2
Dependent Claim
164 words
In a copier having a controller and a platen upon which an original is placed for exposure, a control system for entering dimensional data into the controller, the control system comprising: a first electrically sensitive membrane strip disposed along one axis of the platen, a second electrically sensitive membrane strip disposed along another axis of the platen, the membrane strips being conterminous with the edges of the platen, said membrane strips being formed with touch sensitive portions such that touching by an operator effects a signal indicative of the location of the touch contact, means connecting said strips to the controller for transmitting said signals thereto as indicative of the dimension of the original along the effected edge thereof, and a third electrically sensitive membrane strip, said third electrically sensitive membrane strip electrically connected to the controller and including a conversion switch, activation of said conversion switch enabling the touching of said touch sensitive portions to selectively edit segments of the document related thereto.
Claim 3
Dependent Claim
18 words
The control system of claim 1 wherein the third membrane strip cotorminous with one edge of the platen.
Claim 4
Dependent Claim
35 words
The control system of claim 1 including a plurality of switches for operating upon said original to produce a predetermined copy of said original, said plurality of switches being disposed on the third membrane strip.
Claim 5
Dependent Claim
138 words
In a copier having a controller and a platen upon which an original is placed for exposure, a control system for entering data into the controller, the control system comprising: an electrically sensitive membrane strip disposed near the platen and electrically connected to the controller, said membrane strip being formed with a touch sensitive portion such that touching by an operator effects a first control signal indicative of the touch contact, a conversion switch electrically connected to the controller, activation of said conversion switch enabling the touching of said touch sensitive portion of the electrically sensitive membrane strip to selectively effect a second control signal indicative of the touch control, the second control signal being different than the first control signal and means connecting said membrane strip and the switch to the controller for transmitting said signals thereto.
Claim 6
Dependent Claim
138 words
In a copier having a controller and a platen upon which an original is placed for exposure, a control system for entering data into the controller, the control system comprising: an electrically sensitive membrane strip disposed near the platen and electrically connected to the controller, said membrane strip being formed with a touch sensitive portion such that touching by an operator effects a first control signal indicative of the touch contact, a conversion switch electrically connected to the controller, activation of said conversion switch enabling the touching of said touch sensitive portion of the electrically sensitive membrane strip to selectively effect a second control signal indicative of the touch control, the second control signal being different than the first control signal and means connecting said membrane strip and the switch to the controller for transmitting said signals thereto.
Claim 7
Dependent Claim
164 words
In a copier having a controller and a platen upon which an original is placed for exposure, a control system for entering dimensional data into the controller, the control system comprising: a first electrically sensitive membrane strip disposed along one axis of the platen, a second electrically sensitive membrane strip disposed along another axis of the platen, the membrane strips being coterminous with the edges of the platen, said membrane strips being formed with touch sensitive portions such that touching by an opertor effects a signal indicative of the location of the touch contract, means connecting said strips to the controller for transmitting said signals thereto as indicative of the dimension of the original along the effected edge thereof, and a third electrically sensitive membrane strip, said third electrically sensitive membrane strip electrically connected to the controller and including a conversion switch, activation of said conversion switch enabling the touching of said touch sensitive portions to selectively edit segments of the document related thereto.
Claim 8
Dependent Claim
