PROBLEM TO BE SOLVED: To allow a wheelchair user to make call registration in one action without requiring a circuit modification by applying a wheelchair mark on the surface of a wheelchair user call button. SOLUTION: A general user operates the call button 6 of a general user call button device 5. A call button device 7 is provided with a call button 8 applied with a wheelchair mark. A general user utilizing an elevator pushed the call button 6, and a wheelchair user pushes the call button 8 applied with the wheelchair mark. It is normally inconceivable that the general user pushed the call button 8 with the wheelchair mark by mistake, thereby the erroneous call of the general user can be prevented, and the wheelchair user can make call registration in one action. |
