Claims

[Scope of utility model registration request]

A close-up photographing device to be attached to a rectangular parallelepiped-shaped fixed-focus camera, which includes an auxiliary lens for close-up photography that focuses on a subject at a predetermined close-up distance when attached to the front of the photographing lens of the camera; The objective window and the eyepiece window of the finder section are integrated with an auxiliary lens, and when the optical axis of the auxiliary lens is aligned with the optical axis of the photographing lens of the attached camera, the photographic field of view is directed to the subject at the predetermined close distance. a reflective mirror for focus detection in the center of the objective window, and a total reflection mirror on the side of the objective window at a predetermined distance from the mirror for directing light from the subject to the reflective mirror for focus detection. A distance-measuring finder section that superimposes light from two directions from the subject and directs it to the center of the eyepiece window is attached to a frame that is slidable in the left and right directions on the camera body, and the light from the auxiliary lens is attached to the camera body. When the axis coincides with the optical axis of the photographing lens of the camera, the objective window of the range finder section matches the finder objective window of the camera, and the eyepiece window of the range finder section matches the finder eyepiece window of the camera, and the A close-up photographing device characterized in that the auxiliary lens and the distance measuring finder section are integrally formed so that the frame body can be held in the camera body when the auxiliary lens and the distance measuring finder section are respectively retracted from the front surface of the photographing lens and the finder section of the camera.
