Digital camera with moveable image pickup device

Abstract

A digital camera which includes: a photographic lens movable along an optical axis thereof between a retracted position and a photographing position in front of the retracted position; an image pick-up device on which an object image is formed through the photographic lens, the image pick-up device being guided to be movable between a first position where the image pick-up device is positioned in a photographic optical path of the photographic lens behind the photographic lens and a second position where the image pick-up device is positioned out of the photographic optical path; and a mechanism for moving the image pick-up device between the first position and the second position, wherein the moving mechanism moves the image pick-up device to the first position when the photographic lens is moved from the retracted position to the photographing position, and wherein the moving mechanism moves the image pick-up device to the second position when the photographic lens is moved from the photographing position to the retracted position.

AI Technical Summary

Benefits of technology

[0007]It is an object of the present invention to provide a digital camera having structure which makes it possible to design the camera body to be thin in the direction of the optical axis of the photographic lens of the camera.

Problems solved by technology

In a conventional digital camera, it is difficult to reduce the thickness of the camera body because a bulky image pick-up device is positioned in the camera body behind the photographic lens.

Even if the camera is designed to have a retractable photographic lens for the purpose of reducing the thickness of the camera body when the camera is not in use, it is still difficult to reduce the thickness because a sufficient space in which the photographic lens is to retract cannot be secured in front of the bulky image pick-up device within a thin camera body.
