Claims

[Claims for Utility Model Registration] 1. An electro-optical element whose light transmittance changes according to an applied voltage, and whose reflectance is changed by changing its transmittance. A light-receiving element is provided that simultaneously receives transmitted light and light that does not pass through the electro-optical element or light that passes through a portion of the electro-optical element whose transmittance does not change, and a light-receiving signal from this light-receiving element serves as a set value. An anti-glare mirror according to the above-mentioned type, characterized in that it is provided with a control circuit for controlling the voltage applied to the pneumatic element. 2. The control circuit according to claim 1 of the utility model registration claim, characterized in that the control circuit is configured to change the set value in response to a detection signal from a setting change means that detects the brightness of ambient light. Dazzling mirror.
