PURPOSE:To surely check each person by properly holding the height of a device for checking a lift ticket or the like in a skiing area and opening/closing a gate by simple operation. CONSTITUTION:Lifting mechanisms are built in the right and left parts of opposed gate bodies 19, 20 and operating positions are arranged on movable parts. For instance, a movable side chain A and a fixed side chain B are included in each gate body, a slide case is vertically moved by driving the chain B by the rotation of the chain A to ascend and descent the movable part of the gate body. A locking mechanism is arranged in each fixed interval of vertical strokes. An antenna unit 23 is fixed in the vicinity of a flapper 22 and its angle is turned to a part just before the flapper 22. Two passage check sensors 24 each, tour sensors in total, are arranged front and behind the flapper 22. |
