PURPOSE: An apparatus for automatically switching a dual blind is provided to selectively display moving pictures in a holyday, weekdays, daytime or midnight by automatically converting the dual blind depending on quantity of light. CONSTITUTION: An automatic dual blind switching apparatus includes an optical sensor(80) formed at a front of a window in order to measure quantity of light and generate a measured value thereof for switching a blind cloth(52) of a front screen and a blind cloth(51) of a rear screen. A control section receives the measured value from the optical sensor and generates a signal for switching the blind cloth(52) of the front screen and the blind cloth(51) of the rear screen. A reversible motor(100) is provided to switch the blind cloth(52) of the front screen and the blind cloth(51) of the rear screen when the signal is applied thereto from the control section. |
