TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator call button used in an elevator car call device, a hall call device, a door opening / closing device for opening and closing an elevator door, and the like.
[0002]
[Prior art]
2. Description of the Related Art In elevator car call devices, hall call devices, and the like, electrostatic touch buttons have recently been used as call buttons.
[0003]
This electrostatic touch button detects a call by using the change in capacitance between the touch panel and the ground when the elevator user touches the metal touch panel lightly attached to the button surface. It has the characteristic that it can be operated by just touching it lightly without pressing the button, so it is often used to give a sense of quality.

[Problems to be solved by the invention]
However, since such an electrostatic touch button uses a detection principle of detecting a change in the capacitance to the ground, when the human finger is very dry, or when the human shoe is insulated, it is insulated. When a user touches the electrostatic touch button with his / her finger while wearing high-performance shoes or gloves, the change in the ground capacitance is too small to register the call. was there.
[0006]
In this case, no matter how strongly the electrostatic touch button is pressed, the call cannot be registered, and even if the user wants to use the elevator, the user cannot use the elevator.
[0007]
For this reason, a nameplate for calling attention, such as "Please remove gloves near the call button and operate", is called for, or a voice announcement is used. For wheelchair-specific buttons that require more certainty, instead of using electrostatic touch buttons, use push buttons that do not work unless pushed to some extent, or use door-close and door-open buttons. Only with respect to the buttons related to the sex, there are not a few cases where countermeasures such as using a push button which does not operate unless pushed to some extent without using the electrostatic touch button are taken.
