<p>PURPOSE:To provide a touch panel which is able to control zooming speed of a picture more finely by putting an auxiliary insulating base plate having an electrode on the surface between insulating base plates. CONSTITUTION:An auxiliary insulating base plate 5 is stuck to and laminated on a lower insulating base plate 1 by an adhesive while having a spacer 8 at the end parts and a plurality of spacers 9 kept in a prescribed distance each other in the center parts between them. The opposite side of the auxiliary insulating base plate 5 is stuck to and laminated on an upper insulating base plate 3 by an adhesive while having a spacer 10 at the end parts and a spacer 11 in the center part between them. When a touching face 13 of the insulating base plate 3 of this touch panel 12 is pushed lightly, only an electrode 4 of the insulating base plate 3 and an electrode 7 of the insulating base plate 5 come in contact each other. When the touching face 13 is pushed strongly, further an electrode 6 of the insulating base plate 5 and an electrode 2 of the insulating base plate 1 come in contact each other while the electrode 4 and the electrode 7 keep the contact. Consequently, different signals are generated in the case of pushing the touching face 13 lightly and strongly.</p> |
