Title:
DOOR LOCKING DEVICE
Document Type and Number:
Japanese Patent JP2023066911
Kind Code:
A
Abstract:
To provide a door locking device capable of reducing the number of wirings.SOLUTION: An electrode 21 detects an operation on a door handle 19 by a user when locking or unlocking a door lock 12. An electrostatic detection module 27 inputs the electrostatic capacity of the electrode 21 and detects the operation of the user from changes in the electrostatic capacity. A wiring 30 for the electrostatic detection module 27 to output the detection result to a control unit 8 is constituted of only a single wire. The electrostatic detection module 27 outputs an operation detection notification Sk as the detection result to the control unit 8 via the wiring 30 no matter which electrode 21 detects the operation of the user. The control unit 8 controls at least one operation of the locking and unlocking a door 11 based on the operation detection notification Sk input from the electrostatic detection module 27.SELECTED DRAWING: Figure 1
