Claims

[Scope of utility model registration request]

(1) In a keyless entry device that inputs a coded signal in the form of Morse code to a control circuit using an outer handle switch activated by operating the outer handle of the door in the unlatching direction, a power supply circuit that supplies current from the power supply to the control circuit. A switching element for controlling the power supply circuit on and off is provided, and a holding device is provided for turning on the switching element simultaneously with the operation of the outer handle switch and keeping the switching element in the on state for a predetermined period of time. A power control device for a keyless entry device for automobiles.

(2) The holding device consists of a capacitor that is charged when the outer handle switch is turned on, a resistor provided in the discharge circuit of the capacitor, and a power supply that conducts by conducting the discharge current of the capacitor via the resistor. A power supply control device for a keyless entry device for a motor vehicle according to claim 1, characterized in that the device comprises a second switching element that turns on a switching element of the circuit.

(3) The operation of the outer handle switch is such that an input is input to the holding device by the on/off operation of another switch that is linked to the outer handle switch. A power supply control device for an automotive keyless entry device according to item 1 or 2.
