[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a viewfinder of a camera capable of internally displaying shooting information.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, there is known a camera capable of displaying camera shooting information such as exposure information and strobe information inside a finder. There are several known methods for displaying in the viewfinder, but generally, a light emitting element such as an LED is arranged in the field frame of the viewfinder, and these light emitting elements are turned on to inform the photographer of various shooting information. ing . However, with this method, when the amount of shooting information increases, a large number of light emitting elements are lit in a narrow field frame, and it is expected that shooting errors will occur due to misreading of information.

There is also a method of displaying the entire viewfinder field in color in order to display particularly important shooting information, for example, various warnings such as an out-of-shootable range (near range) warning and a flash charging warning. In this method, the colored transmission plate and the like are moved forward and backward in the optical path of the finder, so that there is a problem in that the mechanism becomes complicated as the number of colors increases.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object thereof is to make it possible to color the inside of a finder and display a plurality of information with a simple structure.

[0005]

[Means for Solving the Problems]

 A first means of the present invention for solving the above-mentioned problems is to provide a viewfinder of a camera having a reflecting surface in the middle of an optical path, wherein the reflecting surface is composed of a semi-transparent mirror and It is characterized in that a light emitting element for photographing information is arranged in the rear and the light emitting element emits light toward a finder optical path at a predetermined time. A second means of the present invention is characterized in that a plurality of light emitting elements having different emission colors are arranged behind the reflecting surface.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall perspective view of a camera to which the present invention is applied. A camera lens 2 is provided in the center of the front surface of a camera body 1, and a distance measuring window 3, 3, a viewfinder window 4, and a flash are provided above the camera lens 2. A light emitting unit 5 is arranged. A shutter button 6 is provided on the upper surface of the camera body, and a viewfinder window 7 is provided on the rear surface of the camera body.

FIG. 2 is a block diagram of the finder system in which other internal mechanisms are omitted. The light of the subject incident from the finder window 3 is reflected by the reflector 10 through the objective lenses 8 and 9 in the perpendicular direction. To do. This reflected light enters the prism 13 via the objective lens 11 and the focus lens 12, and is refracted in the direction of the finder viewing window 7 there. From the viewfinder window 7, the subject image can be seen through the eyepiece lenses 14 and 15.

The reflector 10 is composed of a semi-transparent mirror, and is supported by a support frame 18 at a predetermined angle with respect to the optical path. A diffusing plate 16 is provided on the supporting frame 18 behind the reflecting plate 10, and a light emitting element 17 such as an LED is arranged behind the diffusing plate 16. As the light emitting element 17, a plurality of light emitting elements 17 having different emission colors are arranged according to the type of photographing information to be displayed. However, when there is little information to be displayed, one light emitting element may be used. The shooting information of the present invention includes various warnings such as out-of-shooting range warning, flash charging warning, camera shake warning, and various information necessary for camera shooting such as exposure information and focus information. ..

According to the configuration described above, when the control unit (not shown) determines that the predetermined photographing condition is not satisfied, the light emitting element 17 of a predetermined color emits light according to the output signal from the control unit. This output light is diffused by the diffusion plate 16, passes through the reflection plate 10, and enters the optical path of the objective lens 11, the focus lens 12, the prism 13 and the like described above. Therefore, when viewed from the viewfinder window 7, The viewfinder field is colored so that the photographer can know various kinds of photographing information according to the color.

The light emitting element 17 may be turned on for a predetermined time, but if the blinking time is changed, one light emitting element can display various kinds of information. When the shooting conditions are such that a plurality of pieces of shooting information are output at the same time, the light emitting elements 17 that should emit light may be prioritized.

The above-described embodiment is an example of the present invention, and the configuration of the finder system and the configuration of the camera body shown in the drawings are shown for the sake of convenience, and all of them have a reflector in the optical path of the finder. It can be applied to all cameras.
