Abstract

A shape detection device which can detect the existence/absence or normal/abnormal state of an object and the shape and movement of the object by directly contacting the object. The shape detection device includes a shape detection section having two substrates on which a plurality of electrodes are formed and which are arranged to face each other or in the same direction with a predetermined space therebetween and bonded together by an insulating adhesive filled into the space between the substrates. The shape detection device is manufactured by forming the plurality of electrodes on the substrates, arranging the substrates to face each other or in the same direction with the predetermined space therebetween, bonding the substrates together by filling the insulating adhesive into the space between the substrates, and grinding edge portions of the electrodes formed on the substrates bonded together. The shape detection device can lengthen its life span and can be manufactured at a low cost with superior productivity.

Dependent claims

A shape detection device comprising:

a first substrate,
a first plurality of electrodes disposed in parallel and spaced in relationship to one another on said first substrate,
a second substrate
a second plurality of electrodes disposed in parallel and spaced relationship to one another on said second substrate,
an adhesive securing said substrates together in parallel relationship to one another with said first and second plurality of electrodes disposed in parallel relationship to one another,
said first and second substrates having edges and first and second plurality of electrodes having ends finished to lie in the same plane as said edges to define a shape discrimination surface for detecting shape and direction of movement of an object across said ends of said first and second plurality of electrodes,
said adhesive being disposed within each of or between said first and second pluralities of electrodes and said first and second plurality of electrodes are disposed on said first and second substrates to hold said electrodes rigid and isolated from one another and individually surrounded by said substrates and said adhesive to render said discrimination surface rigid for detecting an object on said discrimination surface.
