Abstract:
A shutter and lens apparatus, which comprises:a lens housing having a cavity; a multi-function support placed in the cavity, having a lens seat and a plurality of extrusions around the cavity in a bottom surface of the multi-function support; a lens positioned in the lens seat; a shutter slice having a shutter aperture, and pivoting on a shaft of the multi-function support for allowing the shutter aperture passing light through the lens by pivoting to the shaft; a diaphragm having a first ape and a second aperture, and pivoting on the shaft for allowing the first aperture or the second aperture to pass the light path; a first solenoid valve attached on a bottom of the multi-function support for controlling the shutter slice pivoting to the shaft; a second solenoid valve attached on the bottom of the multi-function support for controlling the diaphragm pivoting to the shaft; focus adjustment having a focus adjusting gear with a plurality of inclines, the extrusions resting on and moving along the inclines thereby changing altitudes of the multi-function support; a sensor chip base; a sensor chip coupling with the sensor chip base for transforming light passing through the lens into electric output signals; a spring mounted on the multi-function base; and a housing cover encasing the spring, the lens, and the multi-function support in the lens housing, the spring stressed between the housing cover and the multi-function support keeping the extrusions contacting with the inclines while focusing the lens.
