Title:
HOLD DETECTOR AND PRESSURE SENSOR
Document Type and Number:
Japanese Patent JP2017215203
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sensor that has a simple circuit configuration yet a wide detection range.SOLUTION: A sensor 20A comprises a lower substrate 22 attachable to a rim 12, an upper substrate 26 arranged above the lower substrate 22, an electrode pair 80 constituted by a lower electrode 50 attached to the top face of the lower substrate 22 and an upper electrode 60 attached to the underside of the upper substrate 26 facing the lower electrode 50, and a substrate spacer 24 arranged in the periphery of the electrode pair 80. The upper electrode 60 and the lower electrode 50 are constituted by a pressure sensitive electrode. The substrate spacer 24 is arranged between the upper substrate 26 and the lower substrate 22. The sensor 20A is provided with electrode spacers 90A-90C arranged on the inside of the substrate spacer 24 so that the lower electrode 50 and the upper electrode 60 are separated. Both of a first distance from one edge of the electrode pair 80 to the electrode spacer 90A and a second distance from the other edge of the electrode pair 80 to the electrode spacer 90C are shorter than any of a plurality of electrode intervals.SELECTED DRAWING: Figure 9
