Claims

[Scope of Claim for Utility Model Registration] (1) A mirror that reflects the subject light flux incident through the objective lens toward the imaging surface, and the mirror is rotated around the intersection of the optical axis of the subject light flux and the reflecting surface. A camera comprising: a movable mirror adjustment member; (2) A first mirror that is disposed inside the camera body with its reflective surface facing diagonally toward the subject through the objective lens, and bends the incident subject light flux toward the second mirror.
a second mirror that is arranged substantially parallel to the first mirror and guides the bent subject light flux to the imaging plane; and the first mirror or the second mirror,
A camera comprising: a mirror adjustment member that rotates around the intersection of the optical axis of the subject light beam and the reflective surface.
