Filed: 2022-05-17
Abstract: PROBLEM TO BE SOLVED: To improve user convenience while reducing the size of an operation panel in cases where push buttons and non-contact type detection means are installed in an elevator. 
     SOLUTION: Detection means of an operation device for elevators does not detect the arrival of the fingertip of a user in the space area up to the position separated by a first predetermined distance in the orthogonal direction from the surface of a push button to inhibit the detection means from detecting when the user's fingertip comes in contact with the push button, and the detection means detects that the fingertip of the user has arrived at a space from the position separated by the first predetermined distance in the direction orthogonal to the surface of the push button to a position separated by a second predetermined distance in the direction orthogonal to the surface of the push button.
