Abstract: An input device includes an insulation substrate, a switch element, and a detection portion. The switch element includes a fixed electrode portion that is provided on the substrate, and a movable electrode portion that is provided on a main surface side of the substrate, at least part of the movable electrode portion being elastically displaceable toward a direction approaching and leaving the fixed electrode portion. The movable electrode portion is displaceable toward a direction approaching the fixed electrode portion due to pressure from an object to be detected that is an electric conductor. The detection portion is capable of detecting a capacitance change caused by the object to be detected approaching and leaving the movable electrode portion and a capacitance change between the movable electrode portion and the fixed electrode portion produced by displacement of the movable electrode portion due to pressing.

Abstract: An input device 1 includes a panel unit 10, a pressure-sensitive sensor 60 which detects a pressing force applied through the panel unit 10, a seal member 70 which is disposed outside the pressure-sensitive sensors 60, and a support member 80 which supports the panel unit 10 through the pressure-sensitive sensors 60 and the seal member 70. The thickness of the pressure-sensitive sensors 60 is relatively thinner than the thickness of the seal member 70, a space which is formed between the panel unit 10 and the support member 80 includes a first part S1 where the pressure-sensitive sensors 60 are arranged and the second part S2 where the seal member 70 is arranged, and the distance of the first part S1 is relatively narrower than the distance of the second part S2.

Abstract: An electronic apparatus (1) includes a touch panel (40), pressure-sensitive sensors (60), and a control device (90) which is connected to the touch panel (40) and the pressure-sensitive sensors (60). The control device (90) includes a touch panel control unit (91) which outputs a detection signal on the basis of an output value of the touch panel (40), a setting unit (94) which sets, as a reference value (OP0), an output value (OPn) of the pressure-sensitive sensors (60) at a predetermined timing in a case where a detection signal is input from the touch panel control unit (91), and a first calculation unit (95) which calculates, as a first pressure (fn) of the pressure-sensitive sensor (60), a difference between an output value (OPn) of the pressure-sensitive sensor (60) after a predetermined timing and the reference value (OP0). The setting unit (94) individually sets the reference value (OP0) with respect to each of the pressure-sensitive sensors (60).

Abstract: A method for producing a pressure detection device (1) includes a first process (S10) of preparing a pressure-sensitive sensor (2) which includes a first circuit (91) and a second circuit (92) electrically connecting each other in series, the first circuit (91) including a pressure-sensitive body (4) of which an electrical resistance value is consecutively changed according to a pressure, the second circuit (92) including a fixed resistor (5) of which an electrical resistance value can be adjusted to be a desired value; and a second process (S20) of adjusting the electrical resistance value of the fixed resistor (5) on the basis of a ratio (R2:R1) between an electrical resistance value (R2) of at least pressure-sensitive body (4) in the first circuit (91) and an electrical resistance value (R1) of at least fixed resistor (5) in the second circuit (92) in a case where a predetermined pressure is applied to the pressure-sensitive body (4).

Abstract: A switch sheet is used in combination with a substrate having a first contact and a second contact. The switch sheet is comprised of an elastically deformable dome of a conductive material; and a sheet covering the dome and including an embossment projecting from a top of the dome. The sheet is so dimensioned as to have the dome suspended over the first contact and in contact with the second contact.

Abstract: A switch sheet and switch utilizing the switch sheet are provided, wherein the switch sheet utilizes a dome shaped spring, and is structured such that the dome shaped spring can be definitively clicked in the center part and operate effectively even when the dome shaped spring is miniaturized. In addition to having long-lasting, superior durability, this switch sheet provides an improved click ratio enabling miniature devices with a good clicking sensation to be achieved. This switch sheet comprises a dome shaped spring, resin sheeting adhered to the external surface of this dome shaped spring via an adhesive agent, and a rigid member positioned on the outside of this resin sheeting, having a downward facing protrusion part formed to oppose the center part of said dome shaped spring.
