Zusammenfassung:An actuator and a camera shutter apparatus including the same are provided to pick out inferior early since the driving fault can be determined through the assembly of the driving part. A camera shutter apparatus includes a shutter base(100) in which a light through hole(101) the incident light enters is formed on the central part, a plurality of recesses are formed on a part, and a penetration slot is formed on the bottom of the recess; one or more shutter blades positioned in the lower part of the shutter base for blocking the incident light entering through the light through hole of the shutter base; an actuator which comprises a bobbin, a channel type yoke, a rotor, a drive pin and a frame, independently operated to open and close the shutter blade as the rotor rotates at a predetermined angle according to the polarity of the current applied to the coil wound in the bobbin and the drive pin integrally formed on the rotor rotates, and is fixed to the shutter base; a driving part cover(90) which is fixed on the top of the shutter base and fixes the actuator on the settling portion; and an iris cover(80) fixed in the lower part of the shutter base.
