    • An EC panel drive unit for a rear-view mirror comprising a timer circuit 2 in which a drive signal is output for a fixed period of time when either a colored state switch SW1 or a colorless state switch SW2 is in the ON position; a D-type flip-flop circuit 9 that sends different output signals, depending on whether the colored state switch SW1 is in the ON position or the colorless state switch SW2 is in the ON position, and a colored/colorless state switching circuit 6 which switches the polarity of DC voltage that is output from a lithium battery based on the output from the D-type flip-flop circuit 9 and then applies the voltage to input terminals Ta and Tb of the EC panel 7. A contact SW2-3 is installed between the two input terminals, Ta and Tb, of the EC panel 7 for providing a short circuit between the two terminals when the colorless state switch SW2 is turned to the ON position. Switching between a colored state and a colorless state by a one-touch operation, and returning the EC panel 7 to the colorless state from the colored state by pressing and holding the colorless state switch SW3 in cases where trouble occurs such as a drop in output voltage from the lithium battery 1 so as to set the contact SW3-3 to a short-circuit state can be achieved.
