ことができる。 In this improved display device, the outer shape of the display window member 26 (corresponding to the hole 22) on the front side of the camera exterior cover 20 becomes the display area as it is, and the problem with the appearance of the conventional device shown in FIG. 1 can be solved. .
In addition, since the peripheral protrusion 28 is formed as an adhesion margin on the display window member 26, which can be formed into any shape using transparent plastic, etc., the step (peripheral protrusion 28) for adhesion is not so thick. ), and the camera exterior can be made thinner than the one shown in FIG.

When viewing the display, the outer peripheral surface 26a of the display window member 26
The problem arises that the image becomes unsightly as it shines white. or,
As shown in the figure, when there is a strong light source such as the sun from behind the user (photographer), the outer peripheral surface 26a
The white reflection will appear as a white band on the display surface of the liquid crystal display 32, making the display very difficult to read if the contrast is weak in a light-receiving display such as a liquid crystal.

といえる。 In order to prevent reflections on the outer circumferential surface 26a of the display window member 26, it has been proposed that the outer circumferential surface 26a be painted black. It is difficult to perform smear painting, and in reality, it has to be done manually using a brush, which is difficult to implement due to cost issues and yield issues. Also,
Even if the above-mentioned smear painting is performed, it is necessary to form a film in such a way that light is absorbed by the smudges, and it can be said that there are quite a number of restrictions on the implementation of this proposal.
本考案は上記の改良された従来の問題を解決

された液晶表示器である。 FIG. 3 shows a display device as an embodiment of the present invention. Similar to the conventional structure described above, this display device is also arranged at the exterior cover of the camera in order to display camera information. A display window member 46 made of transparent acrylic resin or the like is fitted and adhered from the back side of the camera exterior cover 40. That is, the camera exterior cover 40 is formed with an inclined hole 42 and a large hole 44, and the display window member 46 is also formed with an outer peripheral surface 46a that coincides with the inclined hole 42 and a peripheral protrusion 48 for adhesion. Note that 50 is a low-reflectance black masking print attached to the periphery of the back surface of the display window member 46, and 52 is a liquid crystal display disposed inside.
第４図には表示窓部材４６の外周縁部の拡大図
が示され、次に第４図を含めて本考案の特徴事項
を説明する。 FIG. 4 shows an enlarged view of the outer peripheral edge of the display window member 46. Next, the features of the present invention will be explained with reference to FIG.
すなわち、本考案の特徴は表示窓部材４６の表

効視野角θ1との関係にて決定されるべきである。
すなわち、表示窓部材の材質の空気に対する屈折
率をｎとすると、表示の有効視野角θ1に対し、
nsinθ2＝sinθ1（θ2＝θ−90゜）で定義される傾角θ
（θ2＋90゜）以上の傾斜を表示窓部材４６の外周面

45゜程度あれば実用上充分であり、実施例で表示
窓部材４６の材質をアクリル樹脂としたので屈折
率ｎ≒1.5とすれば、傾角θは次式にて求められ
る。 That is, the feature of the present invention is that the outer circumferential surface 46a is formed at an obtuse angle θ with the display plane of the display window member 46 as a reference plane.
The light directly reflected by the liquid crystal display 6a and the light once reflected from the display surface of the liquid crystal display 52 and reaching the outer peripheral surface 46 are not reflected in the eyes of the user (photographer). The method of determining the inclination angle θ here should be determined in relation to the effective viewing angle θ 1 of the present display device.
That is, if the refractive index of the material of the display window member with respect to air is n, then for the effective viewing angle θ 1 of the display,
Inclination angle θ defined by nsinθ 2 = sinθ 1 (θ 2 = θ−90°)
It is sufficient to form an inclination of (θ 2 +90°) or more on the outer circumferential surface 46a of the display window member 46. To explain specifically, the effective viewing angle of the normal liquid crystal display 52 is
Approximately 45 degrees is practically sufficient, and since the display window member 46 is made of acrylic resin in the embodiment, assuming that the refractive index n≈1.5, the inclination angle θ can be determined by the following equation.
θ2≒28.5゜となり、θ＝（θ2＋90゜）なので、∴
θ≒118.5゜となる。 Since θ 2 ≒28.5° and θ = (θ 2 +90°), ∴
θ≒118.5°.
したがつて、実施例での傾角θは約118.5゜以上
とすれば本考案の効果が得られることになる。な
お、この程度の傾角θの形成であればカメラ外装
カバー４０の傾斜孔４２及び表示窓部材４６の外
周面４６ａは鋭いエツジもしくは傾斜面とはなら
ない為、製造上の問題が生じないことは容易に理
解される。 Therefore, the effects of the present invention can be obtained by setting the inclination angle θ in the embodiment to approximately 118.5° or more. Note that if the inclination angle θ is formed to this extent, the inclined hole 42 of the camera exterior cover 40 and the outer circumferential surface 46a of the display window member 46 will not have sharp edges or inclined surfaces, so it is easy to avoid manufacturing problems. be understood.
又、実用上傾角θを上記の計算値よりも少なめ
に設定したとしても、有害な光の反射により白く
光つて見える光の幅は、第２図に示した従来構造
のものに比べて極めて狭いものとなり、大きく改
善されたことになる。 Furthermore, even if the inclination angle θ is set to a value smaller than the calculated value above, the width of the light that appears white due to the reflection of harmful light is extremely narrow compared to the conventional structure shown in Figure 2. This is a huge improvement.
なお、表示窓部材４６の外周面４６ａに鈍角な
傾角θを設けることにより、外側の開口視野に比
べて内部視野が広くなるが、これはマスキング印
刷５０により適位に視野規制する為、何ら問題は
生じない。 Note that by providing the obtuse inclination angle θ on the outer circumferential surface 46a of the display window member 46, the internal field of view becomes wider than the outside aperture field of view, but this does not pose any problem because the field of view is properly regulated by the masking printing 50. does not occur.
第５図は本考案の他の実施例を示すもので、黒

施例は上述第３図に示した実施例と上記枠６０以
外はほぼ同構造であり、本考案としての効果等も
同様な為、同符号を用いて詳しい説明は省略す
る。 FIG. 5 shows another embodiment of the present invention, in which a display window member 46 is fitted and adhered to the camera exterior cover 40 through a black frame 60 to create contrast in color around the outer periphery of the display surface. It is. This embodiment has almost the same structure as the embodiment shown in FIG. 3 above except for the frame 60, and the effects of the present invention are also the same, so the same reference numerals will be used and detailed explanation will be omitted.
第５図の実施例において、枠６０は特に別体と
して形成する必要はなく、カメラ外装カバーでの
２色形成もしくはホツトスタンプ等にて形成して
も同様な効果が導けるものである。 In the embodiment shown in FIG. 5, the frame 60 does not need to be formed as a separate body, and the same effect can be achieved by forming it in two colors on the camera exterior cover or by hot stamping.
なお、上述した２つの実施例においての表示窓
部材４６の外周面４６ａに形成された傾斜面は、
特に全周に形成する必要はなく、カメラのように
使用者（撮影者）がカメラを持つ形態が決まつて
いるものにあつては、表示装置の配置位置での使
用者の目の位置に応じて特定な面のみ形成すれば
よいことになる。 Note that the inclined surface formed on the outer circumferential surface 46a of the display window member 46 in the two embodiments described above is as follows.
It does not need to be formed around the entire circumference, but in the case of a camera where the user (photographer) holds the camera, it is necessary to form it around the user's eye position when the display device is placed. Accordingly, only a specific surface needs to be formed.
以上、説明したように本考案は従来構造のよう
な表示窓部材の外周面にスミ塗りを必要とせず、
単に外周面を鈍角に形成するだけにて、有害な光
の反射による表示の見にくさを無くした、極めて
低コストにて大量生産に適したカメラ等の光学機
器の表示装置の構造を提供することができる。 As explained above, the present invention does not require smearing on the outer peripheral surface of the display window member as in conventional structures.
To provide a structure of a display device for an optical device such as a camera, which is suitable for mass production at extremely low cost and eliminates the difficulty of viewing the display due to the reflection of harmful light by simply forming the outer peripheral surface at an obtuse angle. Can be done.
