たことを特徴とするドアロツク装置。 Switch 1 and switch from the OFF state to
a first pulse that outputs a first pulse when switching to the N state;
a monostable multivibrator 2, a second monostable multivibrator 3 that outputs a second pulse when the switch 1 is switched from an ON state to an OFF state, and the first and second monostable multivibrator 2. , 3 for unlocking or locking the door lock body by means of the first and second pulses from the door lock device.
A reference value is provided between the switch 1 and the first monostable multivibrator 2, and when the potential difference between the terminals of the switch becomes smaller than the reference value,
A pulse is supplied to the first monostable multivibrator 2 when a current is supplied to the switch and the potential difference is maintained smaller than the reference value, and a pulse is supplied to the first monostable multivibrator 2 when the potential difference becomes larger than the reference value. A door lock device characterized in that a judgment circuit 11, 12, 14, 16, 17 for stopping the supply of pulses to a monostable multivibrator 2 is inserted.
