Claims

[Scope of utility model registration request]

(1) A step motor that is composed of a rotor magnetized in the radial direction, a plurality of stators in which a plurality of magnetic pole portions facing each other are formed on the outer periphery of the rotor, and a coil that excites the stator, and that can be controlled to rotate in forward and reverse directions. , a plurality of sectors forming a lens aperture, a sector drive member for driving the sectors, the step motor and the sector drive member,
In a shutter that has a transmission means such as a connected gear train or the like to control the opening/closing operation of the sector, a determination part that regulates the operating range in the opening and closing directions of the sector is connected to the sector drive member or the transmission means. The step motor is provided in a static stable position where the rotor stops when the coil is de-energized due to the magnetic coupling force between the poles of the rotor and the magnetic pole portion of the stator, and a dynamic stable position where the rotor stops when the coil is energized. and a sector opening/closing device configured such that the rotor stop position, the static stable position, and the dynamic stable position match when the closing direction is regulated by the determining part. .

(2) In the utility model registration claim (1), when the closing direction is regulated by the determining portion before and after the operation of the sector, a predetermined position of the rotor with respect to the coil is regulated. A sector opening/closing device characterized by energizing to maintain a stopped state.

(3) Utility model registration Claim (1) provides an adjusting section for adjusting the phase relationship between the step motor and the sector driving member, and the adjusting section adjusts the phase relationship between the member provided with the determining section and the sector driving member. A sector opening/closing device configured between a sector driving member and a sector driving member.
