Optical lens system for camera

An optical lens system for a camera for image capturing an object, the optical lens system comprising:

• an object image formation member for forming a captured image or a magnified image corresponding to the object, a light source supplying a light beam to the object when the magnified image is formed, optical lenses arranged in front of the object image formation member, an aperture stop area located in a front space of the optical lenses, a spacing space between the optical lenses, or a rear space of the optical lenses, and a switching aperture disposed in the aperture stop area, wherein the switching aperture includes a base plate having an opening for the captured image at a center thereof, a blade provided in the base plate and having a pin hole for the magnified image at a center thereof which decreases a width of the light beam coming from the object to adjust the light beam to have an increased focal depth so that a magnified image corresponding to the object is formed on the object image formation member, a link member connected with the blade as a body, and an actuator connected via the link member with the blade as a body and rotating the link member according to a power supply state to position the blade in an opening non-formation area for the captured image or an opening formation area for the captured image to guide the light beam from the object to pass through the opening for the captured image and form the captured image or to pass through the pin hole for the magnified image and form the magnified image.
