Patent ID: 8376220

Claim:
An automatic teller machine comprising: a chassis; a user interface module rotatably attached to the chassis; and a pair of sliding mechanisms attached to the chassis and the user interface module, each sliding mechanism comprising: a first rail rotatably secured to the chassis, and a second blocking member, separated from the first rail; and a second rail rotatably secured to the user interface module, the second rail being slidable on the first rail, and a latch member with a latch portion rotatably located on the second rail; wherein the user interface module is rotatable between a closed position, where the latch portion is located away from the second blocking member, and an open position, where the latch portion engages with the second blocking member; the first rail comprises a base body, a first sliding flange, and a second sliding flange substantially parallel to the first sliding flange; the first sliding flange and the second sliding flange are located on opposite edges of the base body; the second rail comprises a main body, and a pair of guiding flanges located on opposite edges of the main body; and the first sliding flange and the second sliding flange are slidably engaged with the pair of guiding flanges; the second blocking member comprises a third directing edge, and a fourth directing edge connected to the third directing edge and being substantially a straight line; a first space is defined between the third directing edge and the first sliding flange; a second space is defined between the fourth directing edge and the second sliding flange; the first space and the second space are located on opposite sides of the second blocking member; and the first space and the second space is configured for the latch portion passing through; a first blocking member is located on the first rail and comprises a first guiding edge, a second guiding edge, and a third guiding edge; the first guiding edge abuts the second sliding flange of the first rail; and an obtuse angle is defined between the second guiding edge and the third guiding edge; and the second guiding edge of the first blocking member is configured to rotate the latch member to have the latch portion abut the third directing edge of the second blocking member when the user interface module is rotated from the closed position to the open position; and the fourth directing edge of the second blocking member is configured to have the latch portion abut the third guiding edge after passing through the second space.
