Claims

[Scope of utility model registration request]

(1) In a photographic camera having an objective optical axis and a finder optical axis, a first objective lens, a second objective lens, and a corresponding first finder lens and second finder lens are provided, and at one point in time, one of the two objective lenses and one of the two finder lenses
selectively move each objective lens and each finder lens between a retracted position in which they are out of alignment with their respective optical axes and an actuated position in which they are aligned with their respective optical axes, such that only one of the objective lenses and each finder lens is selectively placed in an actuated position; Each of the finder lenses has two pivot arms protruding in opposite directions along one side thereof, and the pivot arms allow the viewfinder lens to move between the retracted position and the operating position about the pivot arm. each finder lens is provided with an engaging pawl spaced parallel from one of its two pivot arms, the first finder lens and the second finder lens;
the optical axis of the finder lens to rotate the first and second finder lenses about their respective pivot arms; an elongated lens actuating slide movable longitudinally parallel to the lens, extending between the two objective lenses and the lens actuating slide, and coupling means operatively engaged with the objective lens and the slide; is provided, and when the first objective lens is moved to its operating position, the coupling means moves the lens actuating slide in a first longitudinal direction, thereby engaging the first objective lens through the engagement pawl. d When the second finder lens is pivoted about its respective pivot arm into the operating and retracted positions, respectively, and the second objective lens is moved into its operating position, the coupling means longitudinally move the lens actuating slide. and configured to move the second and first viewfinder lenses in a second opposite direction' of the direction, thereby pivoting the second and first viewfinder lenses via the engagement pawls about their respective pivot arms to the actuated and retracted positions, respectively. A camera featuring a thousand features.

(2) The camera according to claim 1, wherein each of the finder lenses, their pivot arms, and engaging claws are formed as one piece of the same material.

(3) The 17th eye is attached to one end of the operating slide.
A slot is formed for receiving the engaging claw of the first finder lens, and when a force is applied through the slot to pull or push the engaging claw of the first finder lens in a direction parallel to the optical axis of the lens. 2. The camera according to claim 1, wherein the first viewfinder lens is configured to be rotated to its operating position or storage position.

(4) Spring-biasing the second finder lens to one of its operating position and retracted position, whereby the lens actuating slide causes the finder lens to move toward the engaging claw of the second finder lens. The second viewfinder lens is configured to be rotated from one of its operating position and storage position to the other position when a pressing force is applied in a direction parallel to the optical axis of the lens. A camera according to claim 3 of the utility model registration claim, characterized in that:

(5) The coupling means further includes a series of interengaging link members for securing the first and second objective lenses to the mounting member, the first of the series of link members
a second link member of the series of link members is engaged with the mounting member to be driven by the mounting member;
a link member is drivingly engaged with the actuating slide, so that when the positions of the two objective lenses are switched, the actuating slide is moved via the series of link members. A camera according to claim 1 of the utility model registration claim.

(6) The mounting member consists of a rotatably mounted plate member, the first and second objective lenses are fixed to the plate member, and when the plate member is rotated in one direction, the first objective lens While the cash register is moved to its operating position, the second objective lens is moved to its storage position, and when the plate part is rotated in the other direction, the first objective lens is moved to its storage position, and the second objective lens is moved to its storage position. The camera according to claim 5, wherein the second objective lens is moved to its operating position, and the first link member includes a cam member protruding from the plate member. . □
