Abstract:
A resistive film type touch panel comprising two resistive-film sheets, which are disposed in opposition to one another with a minute spacing therebetween, said touch panel further comprising:a prescribed power supply means, which is connected so as to generate a prescribed voltage gradient in a selected first resistive-film sheet, a second resistive-film sheet being provided for the purpose of detecting a voltage which corresponds to a pressed position on said touch panel;a switching circuit;a processing/control circuit;an A-D conversion means; anda prescribed storage means,voltage information which corresponds to said pressed position coordinate values detected from said two resistive-film sheets being transferred via said switching circuit to said analog-digital conversion means, which is arbitrarily controlled by said processing/control circuit, determination being performed of said pressed position coordinate value, based on said voltage value, in said analog-digital conversion means, results of said determination being stored in said storage means, a display region and a non-display region outside said display region being formed on said touch panel, and a prescribed function key being disposed in said non-display region, said touch panel further comprising a non-display region pressing detection means which detects a pressing of said non-display region and a notification means which directly notifies said processing/control circuit of an output from said non-display region pressing detection means, without intervention of said analog-digital conversion means.
