Abstract:
1. A mount structure of a touch input device comprising: a touch input device having at least a touch panel, and a pressure sensitive sensor bonded to a lower surface of the touch panel; and a casing dented to have a level difference to allow the touch input device to be externally fitted in, and having a concave part or an opening part for a display device, and a frame-shaped support part to support a back surface peripheral part of the touch input device, in a bottom surface thereof, wherein the pressure sensitive sensor comprises: a first substrate; a second substrate arranged so as to be opposed to the first substrate and bonded to the lower surface of the touch panel; a pair of frame-shaped electrodes arranged on one or both surfaces of a surface of the first substrate opposed to the second substrate and a surface of the second substrate opposed to the first substrate, along an edge part of the first or second substrate; a conductive pressure sensitive ink member arranged on the surface of the first substrate opposed to the second substrate or the surface of the second substrate opposed to the first substrate so as to be apart from at least one of the pair of electrodes, and so as to be along the edge part of the first or second substrate, and having electric characteristics to be changed by a pressed force applied; a gap holding member arranged in a region between the first substrate and the second substrate, to bond the first substrate and the second substrate with its adhesiveness, and hold a gap between the pressure sensitive ink member and at least one of the pair of electrodes; and a pressure concentration member laminated and arranged in a shape of a dot on a surface opposite to the surface opposed to the second substrate, of the first substrate so as to support the pressure sensitive ink member, wherein a frame-shaped gasket is attached between the pressure sensitive sensor and the support part of the casing, and the gasket does not overlap with the pressure concentration member.
