PURPOSE:To reduce the installation space and obtain the delux design by using a light source having a low voltage and a low electric current. CONSTITUTION:An elevator operating button device is equipped with an operation part having operation buttons, electrode place 4 which detects the operation of the operation part and sends out a signal, detecting circuit substrate 7, a plurality of luminous diodes 6a which emit orange color, and a plurality of luminous diodes 6b which emit yellow color and arranged alternately with the diodes 6a. Further, the device is equipped with a light source part which is constituted so that all the luminous diodes emit with the nearly equal luminance when the detecting circuit substrate 7 sends out the detection signal, light diffusion plate 9 which diffuses the light of the light source part and uniformly mixes light, and a design frame 3 which is formed in the operation part and generates a put-ON state through the transmission of the light diffused by the light diffusion plate 9. |
