Abstract
Abstract A telephoto lens having a long focal distance is disposed at an upper location at the side portion of a camera body, and the light passed therethrough is reflected sidewardly of the camera body by a pivotable first mirror. Disposed at an upper location of an exposure station is a second mirror which redirects the light from the first mirror to a third mirror disposed in front of and to the side of the second mirror. Below the third mirror and in a front part of an exposure station, a pivotable fourth mirror is disposed. Mounted at an upper location of the side portion of the camera body is an L-shaped movable lens barrel, in which an ultra telephoto lens having an exceptionally long focal length, and a fifth mirror for reflecting the light passed through the ultra telephoto lens toward the second mirror are disposed. The movable lens barrel is associated with the first mirror. When the movable lens barrel is adjacent the camera body, the camera is in telephotographing mode, and when the movable lens barrel is horizontally pulled up, the camera is in ultra telephotographing mode. In front of the fourth mirror, there is disposed a wide angle lens having a short focal distance. When the fourth mirror is displaced to be in a horizontal state, the camera is in a wide angle photographing mode.

Claim 5
Dependent Claim
23 words
A camera according to claim 3, wherein said fourth mirror is rotatable about a shaft extending parallel to the front of said camera.
Claim 6
Dependent Claim
22 words
A camera according to claim 4, wherein said shaft is connected to a handle provided on an outer side of said camera.
Claim 7
Dependent Claim
39 words

Claim 8
Dependent Claim
138 words
In a camera having in a central region an exposure station, at one side a film take-up chamber, and at the other side a patrone-accommodating chamber; the improvement comprising: an opening formed at an upper side of said camera; a movable lens barrel pivotally mounted in said opening, said barrel being adapted to pivot between a position adjacent to said camera and a position wherein said barrel extends perpendicularly from said camera, said barrel comprising a first lens having a long focal length and a first mirror disposed behind said first lens for reflecting light passing through said first lens toward the interior of said camera body; and mirror means within the camera body for reflecting light from said first mirror toward a back central region of said camera so that said light exposes film in said camera.
Claim 9
Dependent Claim
138 words
In a camera having in a central region an exposure station, at one side a film take-up chamber, and at the other side a patrone-accommodating chamber; the improvement comprising: an opening formed at an upper side of said camera; a movable lens barrel pivotally mounted in said opening, said barrel being adapted to pivot between a position adjacent to said camera and a position wherein said barrel extends perpendicularly from said camera, said barrel comprising a first lens having a long focal length and a first mirror disposed behind said first lens for reflecting light passing through said first lens toward the interior of said camera body; and mirror means within the camera body for reflecting light from said first mirror toward a back central region of said camera so that said light exposes film in said camera.
