PURPOSE:To eliminate the need of providing separate detection means for detecting a position and switching a photographing area, to simplify constitution and to reduce cost by providing an electric detection means capable of consecutively detecting the movement of a photographing optical system between respective areas. CONSTITUTION:A 1st pattern 63a for grounding, a 2nd pattern 63b for photographing, a 3rd pattern 63c, a 4th pattern 63d, and a 5th pattern 63e are arranged from an inner periphery in a pattern 63 for sliding. The photographing optical system supported on a base plate has a wide angle area being a 1st moving range, a shifting area being a 2nd moving range and a telephoto area being a 3rd moving range. Corresponding to that, the pattern 63 is arranged as a whole in a state where a circumference is divided into the wide angle area W being the 1st area, the shifting area N being the 2nd area, and the telephoto area T being the 3rd area. The electric detection means capable of consecutively detecting the movement of the photographing optical system between the respective areas is provided by such constitution. |
