PURPOSE: A switch of an optical filter is provided to switch two filters having different characteristics. CONSTITUTION: A filter A(2) and a filter B(3) are stuck to a filter sticking device(1). The filters are connected with moving shafts(7,8) to be moved inside solenoids(4,5). A metal portion(6) is formed between the center of the moving shafts and receives the magnetic force from the solenoids. The metal portion is moved toward the solenoid(4) when the solenoid(4) has the magnetic force by flowing the electricity. Thereby, the filter(2) is located between a lens and a photographing element by moving the filter sticking device. The filter(3) is located between the lens and the photographing element by moving the metal portion toward the solenoid(5) when the electricity flows toward the solenoid(5). |
