Abstract

PROBLEM TO BE SOLVED: To enable a user to visually confirm the opening/closing state of a barrier just by looking in a finder in a capless camera. SOLUTION: A lens L3 being one of the lenses L1 to L3 constituting the finder is mounted to a lens frame 7 being a other member than a finder frame 6. The lens frame 7 is rotatably supported. A barrier interlocking member 10 linked with a lens cover operating member 2 is provided in the lens frame 7. A housing space 9 for the lens frame 7 and the lens L3 is left between the finder frame 6 and the lens frame 7. When the operating member 2 is pushed up in the case of closing the barrier 3, a sliding member 10 is moved upward and the interlocking member 10 is rotated upward, then the lens frame 7 is turned downward and housed in the space 9 together with the lens L3. Therefore, the optical axis of the lens L3 is deviated from the optical axis of the finder, and a focusing state is not obtained even when the user looks the finder, so that the user visually confirms the closing state of the barrier.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capless camera having a lens cover which is opened / closed in association with the operation of a lens cover operating member and which can display the open / closed state of the lens cover when viewed from a viewfinder.

[0002]

2. Description of the Related Art Various barrier devices have been proposed which can be linked with a lens cover to allow a finder to transmit light or to block light (for example, Japanese Utility Model Laid-Open No. 58-149728). ) However, there is no means for indicating the open state of the barrier in the viewfinder, and even if the user looks into the viewfinder and presses the release button, the shutter may not be released in the closed state of the barrier, and a photo opportunity may be missed. A device that opens and closes the finder by opening and closing the shield in conjunction with the barrier can be considered, but such a configuration requires a place for retracting the shield of the finder when the barrier is opened. However, the capless cameras of recent years have a situation in which there is no room to secure such an evacuation place.

[0003]

In view of such conventional problems, the present invention shifts one or a plurality of lenses constituting the finder from the optical axis of the finder when the barrier is closed, and when the barrier is opened. The retracted lens is returned to the optical axis so that the user can see the open / closed state of the barrier simply by removing the viewfinder, and the retracted position of the lens is placed between the lenses so that no retracted place is needed. The present invention provides a lens cover open / close display device.

In order to achieve the above object, the lens cover opening / closing display device according to claim 1 is a viewfinder in a capless camera having a lens cover which is opened / closed in conjunction with the operation of a lens cover operating member. One or a plurality of lenses among the lenses is a frame separate from the frames of the other lenses, the lens cover operating member is connected to the another frame, and the finder optical axis and the optical axis of the lens held by the separate frame in the closed position. It is characterized in that the optical axis of the finder and the optical axis of the lens held by the separate frame are aligned at the open position so that they are out of focus.

According to a second aspect of the present invention, there is provided a lens cover opening / closing display device which rotatably supports the separate frame and which is linked to the lens cover operating member on the frame so as to interlock with the operation of the lens cover operating member. A barrier interlocking member for rotating the separate frame is provided.

Further, in the lens cover opening / closing display device according to a third aspect, when the separate frame and the lens held by the separate frame are rotated between the frame of the other lens and the separate frame, the separate frame and the lens are provided. It is characterized in that a gap for accommodating is provided.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a lens cover open / close display device according to the present invention will be described below with reference to the drawings. FIG. 1 shows an external appearance of a camera using an embodiment of a lens cover open / close display device according to the present invention. In the following description, the direction is expressed as up or down according to the drawings, but the present invention is not limited to this.

In FIG. 1, there is a lens cover operating member 2 on the front surface of the camera body 1. When this lens cover operating member 2 is operated, the lens cover operating member 2 shown in FIG.
Then, an interlocking member (not shown) is operated, and the barrier (lens cover) 3 is moved to open the window 4 that faces the photographing lens (not shown). In the figure, 5 is a finder window.

FIG. 2 is a front view showing the interlocking of the finder and the barrier for showing an embodiment of the lens cover opening / closing display device according to the present invention, and FIG. 3 is a side view of the same. In these figures, a plurality of lenses L1 to L constituting the finder are shown.
One of the three lenses L3 is attached to a lens frame 7 formed of a member different from the finder frame 6. Although not shown, the lens frame 7 is rotatably supported about a shaft 8. Although not shown in the figure, a spring is linked to the shaft 8 and urges the lens frame 7 so as to be maintained in the state shown by the solid line in FIG. A space 9 for housing the lens frame 7 and the lens L3 is left as it is between the finder frame 6 and the lens frame 7. It should be noted that the number of lenses held by the lens frame 7 which is a separate frame may be plural instead of one.

The lens frame 7 includes a lens cover operating member 2
A barrier interlocking member 10 is provided for linking with
Slide member 1 operated by lens cover operating member 2
It is in contact with a protrusion 12 provided at one end of the No. 1. Further, the other end of the slide member 11 contacts an arm member 13 for moving the barrier 3 up and down, and the arm member 13 has a spring 14
Thus, the barrier 3 side is urged to rotate upward.

Next, the operation of this example will be described. When the lens cover operating member 2 is operated to push up the barrier 3 to close it, the slide member 10 moves upward in conjunction with this, the barrier 3 closes the window 4, and the barrier interlocking member accordingly. 10 is pushed up by the projection 12 and rotates upward, while the lens frame 7 rotates downward and is housed in the space 9 together with the lens L3. As a result, the optical axis of the lens L3 is deviated from the optical axis of the finder, and the user cannot see the finder even when looking into the finder, whereby the user can visually recognize that the barrier is closed.

On the other hand, when the lens cover operating member 2 is operated and pushed down when the barrier 3 is opened, the slide member 10 is not pushed up by the projection 12 and the lens frame 7 and the lens L3 are linked by the spring linked to the shaft 8. By turning back on the optical axis and looking into the finder, the subject comes into focus, so that the user can visually recognize that the barrier is open.

[0013]

As described above, the lens cover open / close display device according to the present invention includes one or a plurality of lenses forming a finder lens in association with the closing operation of the member for opening and closing the lens cover. Since the optical axis is shifted from the optical axis and the subject is out of focus, there is an effect that the user can immediately recognize the opened / closed state of the barrier by looking into the finder.

In the lens cover open / close display device according to the third aspect of the present invention, the gap for displacing the lens displaced from the optical axis and the frame holding it is left between the frame of the lens forming another finder. The effect is that it is not necessary to secure a dedicated space.
