きさから自ずから制限がある。 In Japanese Patent Application No. 59-047934, pores or slits are provided at equal intervals on a circumference centered on the center of the shaft in a light-shielding plate attached to the same shaft on which a movable electrode plate is attached. Two photo sensors are provided at regular intervals on the circumference of a pore or slit to detect the direction and angle of rotation of the movable electrode plate. For the most efficient use of the pores or slits, two photo sensors must be placed between adjacent pores or slits. In order to accurately detect the movement of the movable electrode plate, the distance between the pores or slits must be made small, and on the other hand, the minimum distance between two photo sensors is naturally limited due to the size of the photo sensors.

The figure is a plan view showing a specific example of the capacitor type rotary electrostatic voltmeter of this invention, and 1 and 1' are a pair of movable electrodes provided symmetrically with respect to the axis 3. 2 and 2' are fixed electrodes, each consisting of two metal plates (upper and lower), and the movable electrode plate is designed to be able to fit between the two metal fixed electrode plates without contacting them, so that the fixed electrode plate is not charged. When applied, the Coulomb force causes the movable electrode plate to rotate around the shaft 3 against the drag force of an overwound spring attached to the shaft 3. The movable electrode plates 1 and 1' each have a plurality of gaps A 1 , A 2 , A 3 , ..., A o and
B 1 , B 2 , B 3 , ..., B o are provided on the circumference centered on the center of the shaft 3, and the gaps B 1 , B 2 , B 3 , ..., B o
