Total Claims: 6
Claim 1
Independent Claim
253 words
A signal input sheet comprising: a flexible upper laminate having a lower surface and an upper surface, said upper laminate having one of a conductive layer and a resistive layer on its lower surface as a first layer, said upper surface of the upper laminate being divided into at least one hand-written input area for the input of characters and lines and at least one binary data input area for the input of single depressions; a lower laminate having a lower surface and an upper surface, said lower laminate having one of a conductive layer and a resistive layer on its upper surface as a second layer, where said first layer faces said second layer and at least one of said first layer and said second layer being formed as a resistance layer; a plurality of insulative spacers interposed between said first layer and said second layer, said insulative spacers arranged at intervals such as to allow an electrical connection between said first layer and said second layer, where a depressing pressure on the upper surface of said upper laminate causes the electrical connection between said first layer and said second layer, said insulative spacers having a larger width in said binary data input area and having a larger spacing between adjacent insulative spacers in said binary data input area; a voltage source coupled between said first layer and said second layer; and means for detecting a position at which said depressing pressure is applied on the upper surface of said upper laminate.
Claim 2
Dependent Claim
253 words
A signal input sheet comprising: a flexible upper laminate having a lower surface and an upper surface, said upper laminate having one of a conductive layer and a resistive layer on its lower surface as a first layer, said upper surface of the upper laminate being divided into at least one hand-written input area for the input of characters and lines and at least one binary data input area for the input of single depressions; a lower laminate having a lower surface and an upper surface, said lower laminate having one of a conductive layer and a resistive layer on its upper surface as a second layer, where said first layer faces said second layer and at least one of said first layer and said second layer being formed as a resistance layer; a plurality of insulative spacers interposed between said first layer and said second layer, said insulative spacers arranged at intervals such as to allow an electrical connection between said first layer and said second layer, where a depressing pressure on the upper surface of said upper laminate causes the electrical connection between said first layer and said second layer, said insulative spacers having a larger width in said binary data input area and having a larger spacing between adjacent insulative spacers in said binary data input area; a voltage source coupled between said first layer and said second layer; and means for detecting a position at which said depressing pressure is applied on the upper surface of said upper laminate.
Claim 3
Dependent Claim
21 words
A sheet according to claim 1, wherein said upper laminate further has a non-input area which does not sense an input.
Claim 4
Dependent Claim
42 words
A sheet according to claim 2, wherein the distribution of the insulative spacers on the lower side of the non-input area is equal to or finer than the distribution of the insulative spacers on the lower side of the hand-written input area.
Claim 5
Dependent Claim
17 words
A sheet according to claim 1, wherein the insulative spacers are respectively independently formed from the other.
Claim 6
Dependent Claim
44 words
A sheet according to claim 4, wherein each of the insulative spacers on the lower side of the binary data input area has a shape larger than a shape of each of the insulative spacers on the lower side of the hand-written input area.
