"￢" type of the first drive gear 118 to stop the rotation of the inner locking device operating lever (5 ') rotated to lock the door lock when the motor 112 is driven under the control of 1). And a second light sensing unit 140 for sensing the protrusion 120.

The automatic and manual combined card key door lock configured as described above will be described as follows.

First, when unlocking the automatic and manual combined card key door locks assigned to the door, the card key 1 that has been magnetized in advance (password input) is inserted into the card insertion unit 204.

At this time, when the password of the card key 1 and the magnet pin 3 set on the magnet housing 4 coincide, the magnetic plate 2 is moved downward by the card key 1.

Accordingly, the micro switch 22 is electrically switched on by the magnet plate 2.

The micro switch 22 sends an electric signal to the control IC 116-1 installed on the printed circuit board 116.

The control IC 116-1 transmits an open driving signal of the door lock to the motor 112 installed at the other side of the battery cover.

Accordingly, the motor 112 is rotated forward.

In addition, the first driving gear 118 connected to the motor 112 is operated, and the second driving gear connected to the first driving gear 118 is operated.

Thus, the inner locking device operating lever 5 'connected to the other side of the first driving gear 118 is operated.

At this time, the "￢" shaped protrusion 120 of the first driving gear 118 is rotated, and the first light sensing unit 130 is configured to stop the rotation of the inner locking device operating lever 5 ′. The “￢” shaped protrusion 120 of the first drive gear 118 is sensed.

Here, when the "￢" type protrusion 120 is sensed by the first light sensing unit 130, the first light sensing unit 130 stops driving the motor 112 by the control IC 116-1. Send a control signal.

On the contrary, when the automatic and manual combined card key door lock is locked, the user presses the lock switch 202.

Accordingly, the control IC 116-1 installed on the printed circuit board 116 transmits the closed driving signal of the door lock to the motor 112 installed on the other side of the battery cover.

Accordingly, the motor 112 is reversed.

In addition, the first driving gear 118 connected to the motor 112 is operated, and the second driving gear connected to the first driving gear 118 is operated.

Thus, the inner locking device operating lever 5 'connected to the other side of the first driving gear 118 is operated.

At this time, the "￢" shaped protrusion 120 of the first driving gear 118 is rotated, and the second light sensing unit 140 is configured to stop the rotation of the inner locking device operating lever 5 ′. The “￢” shaped protrusion 120 of the first drive gear 118 is sensed.

Here, when the "￢" type protrusion 120 is sensed by the second light sensing unit 140, the second light sensing unit 140 stops driving the motor 112 by the control IC 116-1. Send a control signal.

On the other hand, when the door lock is manually unlocked because electric operation of the door lock is not possible in the house, the user grasps and rotates the inner locking device operating lever 5 'by hand.

Accordingly, the second drive gear is operated.

Thus, the locking device and the locking device locked to the door are released.

On the contrary, when the automatic and manual combined card key door lock is locked, the user grasps and rotates the inner locking device operating lever 5 'by hand.

Accordingly, the second drive gear is operated.

Thus, the locking device and the locking device are locked to the door.

On the other hand, when the door lock is unlocked manually because the electric operation of the door lock is not possible outside the house, the card key 1 is inserted into the card insertion unit 204.

At this time, the magnetic plate 2 is moved downward by the card key (1).

Then, the user grabs and turns the external locking device operating lever 5 by hand.

At this time, the second driving gear is operated.

Thus, the locking device and the locking device are released.

On the contrary, when the door lock is manually locked because the door lock is not electrically operated outside the house, the user grabs and rotates the external lock device operating lever 5 by hand.

Accordingly, the second drive gear is operated.

Thus, the locking device and the locking device locked to the door are released.

As described above, the automatic and manual dual-use card key door lock according to the present invention pursues convenience through the electric method of the parts, and the use of the battery consumes, the poor contact of the electronic circuit, the failure caused by moisture, etc. When a problem occurs, it is operated by a simplified mechanical mechanism, which increases the reliability of the security device and has the advantage that the user does not have a problem in use in an emergency.
