Abstract

PURPOSE: To obtain the camera which is also able to serve as binoculars by dividing the light passed through an objective lens to two and letting the same pass through separate two eyepieces.
CONSTITUTION: Light entering through an objective lens 1 is first reflected by a mirror 2. Next, this reflected light is passed through focus glass 3 and is reflected by a pentagonal roof prism 4. The light is then divided into two directions by a half mirror 5. Half of the light passes here, reflects on a rectangular prism 6, further reflects on a rectangular prism 7 and passes through an eyepiece 8. Also, the one light divided by the half mirror 5 reflects on the half mirror 5, reflects on a rectangular prism 9 and passes through an eyepiece 10. Controlling the focus of the finder with the focus glass 3 is the same as that with ordinary cameras. Since this camera is so made as to permit viewing the subject with both eyes, it is convenient.
