Abstract

The present invention relates to a two-stage lock structure of an ATM that can prevent an operator from being injured during the removal of a currency note jam. The two-stage lock structure includes: a temporary stack to be moved upward by rotating about a temporary stack hinge shaft to open a conveyance path when a currency note jam occurs; a protruding member protruding from one surface of the temporary stack; a stopper that includes a first aperture and a second aperture into which the protruding member is inserted to hold the temporary stack rotated about a hinge shaft, and a slide aperture in which the protruding member slides and is rotated about a stopper hinge shaft; and an elastic member provided to pull the stopper in a direction where the protruding member is held in the first or second aperture.

Claims

1. A two-stage lock structure of an automatic teller machine, 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;

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 closed 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.

6. A two-stage lock structure of an automatic teller machine, the two-stage lock structure comprising:

an upper frame that is provided above a lower frame and is moved upward by rotating about a frame hinge shaft, when a currency note jam occurs, in order to open a conveyance path;

a supporting member having one end hinge-connected to the lower frame and the other end provided with a catching portion;

a locking lever having one end hinge-connected to one surface of the upper frame and the other end provided with first and second protrusions, the first or second protrusion being caught by the catching portion of the supporting member so as to prevent the upper frame from descending when the upper frame is moved upward by rotating about the frame hinge shaft; and

an elastic member provided to pull the locking lever in a direction where the first or second protruding member is caught by the catching portion of the supporting member and held.

7. The two-stage lock structure according to claim 6, wherein a gas spring is provided between the upper frame and the lower frame, and

when the upper frame is rotated about the frame hinge shaft, the upper frame does not descend due to a supporting force of the gas spring.

8. The two-stage lock structure according to claim 7, wherein each of the supporting member and the locking lever has a U-shaped cross-section,

a piston rod and a cylinder of the gas spring are provided to pass through the U-shaped cross-sections of the supporting member and the locking lever, and

a direction corresponding to an opening of the U-shaped cross-section of the supporting member is different from a direction corresponding to an opening of the U-shaped cross-section of the locking lever.

9. The two-stage lock structure according to claim 6, wherein each of the first and second protrusions of the locking lever has a shape of a right-angle triangle.

10. The two-stage lock structure according to claim 6, wherein the elastic member is a spring that has one end connected to the locking lever above the locking lever hinge shaft and the other end connected to the upper frame at a predetermined position.

11. The two-stage lock structure according to claim 6, wherein when the first or second protrusion is caught by the catching portion of the supporting member, an upper end of the locking lever protrudes from the upper surface of the upper frame, and

when the upper end of the locking lever is pressed, the first or second protrusion is released from the catching portion against the elastic force of the elastic member.

12. The two-stage lock structure according to claim 6, wherein a separation preventing protrusion protrudes from the catching portion in order to prevent the first and second protrusions of the locking lever from being separated from the catching portion.
