Abstract

A two-stage lock structure of an ATM is described that can prevent an operator from being injured during the removal of a currency note jam.

Claims

1. A two-stage lock structure, the two-stage lock structure comprising:

a temporary stack to be moved upward about a temporary stack hinge shaft to open a conveyance path when a currency note jam occurs in an automatic teller machine;

a protruding member protruding from one surface of the temporary stack;

a stopper that includes a first aperture, a second aperture formed above the first aperture, and a slide aperture and is moved by rotating about a stopper hinge shaft, the first and second apertures being formed so that the protruding member is inserted into and caught in the first or second aperture to hold the temporary stack rotated about the temporary stack hinge shaft, and the slide aperture being formed so that the protruding member slides in the slide aperture when the conveyance path formed below the temporary stack is opened; and

an elastic member provided to pull the stopper in a direction where the protruding member is held in the first or second aperture.

2. The two-stage lock structure according to claim 1, wherein a handle is formed at a predetermined upper portion of the stopper.

3. The two-stage lock structure according to claim 1, wherein the protruding member has a cylindrical shape, and

the stopper includes:

a first catching portion inclined downward from a round end, which is formed between the slide aperture and the first aperture, toward the first aperture; and

a second catching portion inclined downward from a round end, which is formed between the first and second apertures, toward the first aperture.

4. The two-stage lock structure according to claim 3, wherein a convex guiding portion is formed in the stopper so as to face the second catching portion.

5. The two-stage lock structure according to claim 1, wherein the elastic member is a torsion spring wound around the stopper hinge shaft.
