Abstract
A resistive film type input device includes: a resistive film which is formed on a surface of the first insulating substrate opposed to the second insulating substrate; feeding electrodes which apply a voltage to the resistive film on the first insulating substrate; a detecting electrode films which are formed on a surface of the second insulating substrate are in an electrically floating state; and a potential detecting unit which detects a potential of a contact location of the resistive film through the detecting electrode film contacted to the resistive film among the detecting electrode films by pressing against.
Claims10
A resistive film type input device comprising:
- a first insulating substrate;
- a second insulating substrate which is disposed opposite the first insulating substrate with a gap interposed therebetween;
- a resistive film which is formed on a surface of the first insulating substrate opposed to the second insulating substrate;
- feeding electrodes which apply a voltage to both end portions of the resistive film on the first insulating substrate;
- a plurality of detecting electrode films which are formed on a surface of the second insulating substrate opposed to the first insulating substrate and are in an electrically floating state;
- and
- a potential detecting unit which detects a potential of a contact location of the resistive film through the detecting electrode film contacted to the resistive film among the plurality of detecting electrode films by pressing against the first insulating substrate or the second insulating substrate.
