- An aperture device using a drive ring is generally used in high-end cameras because of its complicated structure and large size.
- low-cost cameras and digital cameras have become widespread. Therefore, there is a growing demand for a smaller aperture device with a simple structure, with the aperture limited to about two to four steps.
- Patent Document 1 An aperture device that is reduced in size by limiting the number of aperture steps is disclosed in Patent Document 1, for example.
- the aperture device disclosed in Patent Document 1 two small aperture blades having different small aperture holes are arranged so as to be swingable. Then, the two small aperture blades are selectively driven by the drive pins to block the lens aperture, thereby forming a fully open state, a first small aperture state, and a second small aperture state.
- a two-stage small aperture state can be formed with a simple configuration.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2001-188276
- the drive pin is used only to move the diaphragm blade to the lens opening position. Therefore, a return panel for returning the aperture blades to the standby position (or the retreat position) is provided. Further, a determining pin is provided so that the aperture blade which receives the urging force of the return panel stops at a predetermined standby position. In such a configuration, since the return panel force is always applied to the aperture blade, the drive pin is driven. It is necessary to employ a large actuator that operates in consideration of the load. In addition, as described above, it is necessary to provide a determining pin (a positioning member) for stopping the aperture blade at the standby position, so that the number of components increases.

Therefore, a different aperture state can be formed by swinging the small aperture sector without using a return panel. Further, since the small aperture sector can be held at the retracted position by the cam groove, a positioning member is not required, thereby simplifying the configuration and promoting downsizing.
- the drive pin can move to first and second positions located on both sides of the initial position, and when the drive pin moves to the first position, the first The small aperture sector shields the lens aperture to form a first aperture state, and when the drive pin moves to the second position, the second small aperture sector shields the lens aperture.
