Problems solved by technology

[0004] In the above-mentioned prior art, since the support shaft for hanging down the misoperation prevention plate must be arranged directly above the key, it is impossible to install the misoperation prevention when there is some interfering object such as the communication hole of the external communication device directly above the key. board, that is, there is a problem that it is easy to be restricted by interference around the key when installing the misuse prevention board

Abstract

The invention provides a key misoperation avoiding device capable of easing restriction produced by interference objects around a key when a misoperation preventing plate is installed. The key misoperation avoiding device is provided with the surface of the key (17), the misoperation preventing plate (2) arranged on the surface in the vertical direction, a supporting shaft (16) arranged around the key (17) and rotatably supporting the misoperation preventing plate (2) and a through hole (13) for the supporting shaft (16) to be inserted into the misoperation preventing plate (2), wherein the surface can cover an operating panel of an elevator and output a signal according to press operation. The key misoperation avoiding device is provided with a limiter (4), wherein the limiter (4) defines a rotating angle of the misoperation preventing plate (2) as an angle from the position of the surface covering the key (17), of the misoperation preventing plate (2), to the position where the key (17) is not covered, of the misoperation preventing plate (2), and keeps the angle to be an acute angle.

Description

technical field [0001] The invention relates to a device for avoiding misoperation of keys. Background technique [0002] Generally speaking, a normal button provided on an operation panel related to the operation of a machine outputs a signal to realize an original function in accordance with a pressing operation, but other than such a normal button, it is common to use a button on the operation panel. There is a button that is pressed and operated to output a signal in an emergency (emergency) etc. For example, on an elevator, in addition to the common buttons, the operation panel provided in the car is also provided with a button for the passengers locked in the car to communicate with the outside, that is, an emergency call button. However, since such an emergency call button is arranged on the operation panel side by side with ordinary buttons, misoperation may occur. [0003] In view of this situation, Patent Document 1 (Japanese Patent Application Laid-Open No. 5-19...
