An automatic teller machine includes a chassis, a user interface module; and a pair of sliding mechanisms. The user interface module is rotatably attached to the chassis. The pair of sliding mechanisms are attached to the chassis and the user interface. Each sliding mechanism includes a first rail and a second rail. The first rail is rotatably secured to the chassis. A second blocking member is located on the first rail. The second rail is rotatably secured to the user interface module and slidable on the first rail. A latch member with a latch portion is rotatably located on the second rail. 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.
