PROBLEM TO BE SOLVED: To enhance the degree-of-freedom in the shape of a flexible substrate, on which a sensor is mounted, without lowering the detection accuracy of a sensor for detecting the type of a switched member, when switching a plurality of types of ND filter by the rotation operation of a rotary dial.SOLUTION: In an electronic apparatus, a sensor 124a arranged on the same circumference as an outer annular rib 109a having four notches 109c formed therein and detecting presence or absence of the notch 109c, and two sensors 124b, 124c arranged on the same circumference as an inner annular rib 109b having a semicircular notch 109d formed therein and detecting presence or absence of the notch 109d are mounted on a flexible substrate 124. When a CPU determines the type of an ND filter switched based on the detection results from the sensors 124a, 124b, 124c, combination of detection results from the sensors 124b, 124c is different at a timing of the sensor 124a for detecting the four notches 109c individually. |
