Manual information input device
First Claim
1. A manual information input device comprising:
- a substrate supporting electrodes on one surface thereof;
a resilient input panel disposed in facing relation to said substrate and supporting electrodes in confronting relation to said electrodes on the substrate;
a spacer disposed between said substrate and said flexible input panel and defining a closed space therebetween;
an electrically insulating, flowable, viscous material sealed in said space;
said electrodes on said substrate and said input panel jointly constituting a pixel matrix; and
said electrically insulating material comprising a group of particles and/or a liquid, said liquid filling said space when it is sealed in said space either singly or in combination with said group of particles.

Abstract
A manual information input device allows the user to manually enter desired information using a readily available writing instrument such as a pencil rather than a specially designated input stylus such as a light pen or an electromagnetic pen. The manual information input device comprises a substrate supporting electrodes on one surface thereof, an input panel disposed in facing relation to the substrate and supporting electrodes in confronting relation to the electrodes on the substrate, a spacer disposed between the substrate and the flexible input panel and defining a closed space therebetween, and an electrically insulating material sealed in the space. The input panel is resilient. The electrodes on the substrate and the input panel jointly constitute a pixel matrix. The electrically insulating material comprises a liquid and/or a group of particles.

9. A manual information input device comprising:
-
a substrate and a resilient input panel which are substantially coextensive and parallel but spaced from each other to define an interior space between them; first electrodes which are supported on the substrate and face the panel and second electrodes which are supported on the panel and face the substrate, wherein said first and second electrodes are normally out of electrical contact with each other; electrically insulating, viscous flowable material which is enlcosed in said interior space between the substrate and panel and (i) comprises electrically insulating particles having a dispersion rate greater than 10 particles per square mm and size of 0.1 micrometes to 2 mm, and (ii) has flow properties which allow the material to flow away from the pressed area when the panel is pressed toward the substrate with a pointed instrument to permit ohmic contact between a first electrode and a second electrode but not when the input panel is pressed toward the substrate with a user'"'"'s hand or finger. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A manual information input device comprising:
-
a substrate and a resilient input panel which are substantially coextensive and parallel but spaced from each other to define an interior space between them; first electrodes which are supported on the substrate and face the panel and second electrodes which are supported on the panel and face the substrate, wherein said first and second electrodes are normally out of electrical contact with each other; electrically insulating, non-gaseous material which is enclosed in said interior space between the substrate and panel but is not affixed to the substrate or panel and flows away from the pressed area when the panel is pressed toward the substrate with a pointed instrument to permit ohmic contact between a first electrode and a second electrode but not when the input panel is pressed toward the substrate with a user'"'"'s hand or finger, said material comprising electrically insulating particles having a dispersion rate greater than 10 particles/mm2 and size of between 0.1 micrometer and 2 mm. - View Dependent Claims (20)
