Document Type and Number:
Japanese Patent JP2021005833
Kind Code:
A
Abstract:
To provide a signal input device capable of suppressing parts cost.SOLUTION: A signal input device 30 includes: a first electrode 32 to which external signals are input; a second electrode 33 arranged so as to face the first electrode 32 with an insulating layer 31 therebetween; a reference signal generation unit 35 that generates a reference signal of a predetermined frequency; a resistance 34 connected between the reference signal generation unit 35 and the second electrode 33; and an input circuit 36 that is connected to the second electrode 33 and detects an external signal input to the first electrode 32 based on the changes the of a reference signal when a reference signal is applied to the second electrode 33 from the reference signal generation unit 35 via the resistance 34.SELECTED DRAWING: Figure 2
