Touch panel apparatus with piezoelectric element
First Claim
1. A touch panel apparatus comprising:
- a touch panel;
a piezoelectric element disposed on the touch panel and capable of expansion and contraction; and
a plurality of support members disposed on a fixing portion and configured to support and allow for flexure vibration of the touch panel, whereinthe support members are disposed in greater number in a direction intersecting an expansion and contraction direction of the piezoelectric element than in the expansion and contraction direction so that a bending direction of the touch panel due to a press matches a flexure direction of the touch panel due to the expansion and contraction of the piezoelectric element, andamong at least the support members disposed in the direction intersecting the expansion and contraction direction, each support member disposed between outermost support members has a larger elastic coefficient than the outermost support members.

Abstract
A touch panel apparatus includes a touch panel (11), a piezoelectric element (12) disposed on the touch panel (11) and capable of expansion and contraction, and a plurality of support members (14a-14f) disposed on a fixing portion (13) and configured to support and allow for flexure vibration of the touch panel (11), such that the support members (14a-14f) are disposed in greater number in a direction orthogonal to an expansion and contraction direction of the piezoelectric element (12) than in the expansion and contraction direction so that a bending direction of the touch panel (11) due to a press matches a flexure direction of the touch panel (11) due to the expansion and contraction of the piezoelectric element (12).

1. A touch panel apparatus comprising:
-
a touch panel; a piezoelectric element disposed on the touch panel and capable of expansion and contraction; and a plurality of support members disposed on a fixing portion and configured to support and allow for flexure vibration of the touch panel, wherein the support members are disposed in greater number in a direction intersecting an expansion and contraction direction of the piezoelectric element than in the expansion and contraction direction so that a bending direction of the touch panel due to a press matches a flexure direction of the touch panel due to the expansion and contraction of the piezoelectric element, and among at least the support members disposed in the direction intersecting the expansion and contraction direction, each support member disposed between outermost support members has a larger elastic coefficient than the outermost support members. - View Dependent Claims (2)

3. A touch panel apparatus comprising:
-
an oblong touch panel; a piezoelectric element disposed along a short side of the touch panel and capable of expansion and contraction in a short side direction; and a plurality of support members disposed on a fixing portion and configured to support and allow for flexure vibration of the touch panel, wherein the support members are disposed at four corner portions of the touch panel and between the corner portions on long sides of the touch panel so that a bending direction of the touch panel due to a press matches a flexure direction of the touch panel due to the expansion and contraction of the piezoelectric element, and among at least the support members disposed in the direction parallel to the long sides of the touch panel, each support member not disposed at the corner portions has a larger elastic coefficient than the support members disposed at the corner portions. - View Dependent Claims (4, 5)
