In addition, if the key is lost, even a legitimate right holder can not access the key. In case of the password input method, there is a disadvantage that the password may be lost or leaked out by an unauthorized method by others. As biometric and recognition processing technology is required, it has a disadvantage that it is difficult to apply in a real market because the manufacturing cost is increased when it is applied to a door lock device.

In addition, when the door is to be opened in a state in which the door is unlocked, the door is opened when the door is first opened by rotating the handle in one direction and then pushing or pulling the door continuously. In other words, the door must be opened by pushing or pulling the door while the user holds the door handle by the hand and rotates, thereby making it difficult to open the door.

Particularly, the continuous operation in which the door is pushed or pulled in a state in which the handle of the door is rotated by one hand while being held by the hand is difficult for the child, the elderly, and the disabled to rotate the door handle, When a user holding a goods wants to access, there is an inconvenience that the carrying object should be lowered on the floor, then the door should be opened, and then the object should be carried in or out again.

Recently, an opening / closing device for opening and closing the door by simply pushing or pulling the handle has been proposed without rotating the door handle, but most of the structure is complicated, many parts are used and it is difficult to assemble, The operation is not smooth and the accuracy of opening and closing is reduced.

In addition, the structure for opening and closing the door by pushing or pulling the handle has a problem that the door is locked by only the latch bolt, so that the security is poor and the door is not suitable for the entrance for the outsider.
