に保持している。FIG. 4 shows a general color picture tube, in which an envelope 1 made of glass has a funnel 3 integrally joined to a panel 2, and the funnel 3 is provided with a neck portion 4. An electron gun 6 that emits and focuses a plurality of electron beams 5 is disposed inside the neck portion 4 of the envelope 1, and is mounted on the inner surface of the panel 2 of the envelope 1, facing the electron gun 6. A phosphor screen 7 is formed. The phosphor screen 7 is composed of striped or dot-shaped phosphor layers that emit red, green, and blue colors, respectively. An inner wall of this phosphor screen 7 and a shadow mask structure 8 are provided. In this shadow mask structure 8, a shadow mask 10 having a large number of electron beam passing holes 9 through which the electron beam 5 from the electron gun 6 passes is fixed to the front part of a rectangular bar-shaped mask frame l1.
A frame support 12 is fixed to the outside of the four sides of 1. This frame support 12 engages with a pin (not shown) protruding from the inner wall of the panel 2, and the mask frame 11
is supported in the envelope 1, and a shadow mask 10 is held close to and opposite to the phosphor screen 7 so that a predetermined distance is maintained between the shadow mask 10 and the phosphor screen 7.
また、前記マスクフレーム１１に前記ファンネル３の内
面に沿うほぼ截頭角錐状の磁気シールド体１３が固定さ
れている。Further, a substantially truncated pyramid-shaped magnetic shield body 13 is fixed to the mask frame 11 along the inner surface of the funnel 3 .
なお、図示しないが、前記ファンネル３からネック部４
の外壁にかけて電子ビーム５を偏向走査する偏向ヨーク
が装着されている。Although not shown, from the funnel 3 to the neck portion 4
A deflection yoke for deflecting and scanning the electron beam 5 is attached to the outer wall of the electron beam.
そして、電子銃６から射出された電子ビーム５がシャド

の内面の蛍光体スクリーン７、すなわち、赤、緑、青の
それぞれの色に発光する蛍光体層に射突し、これら各蛍
光体層を発光させて、画像を映出する。After the electron beam 5 emitted from the electron gun 6 passes through the electron beam passage hole 9 formed in the shadow mask 10, a panel 2 is placed opposite to the shadow mask 10.
The light impinges on the phosphor screen 7 on the inner surface, that is, the phosphor layers that emit light in red, green, and blue colors, causing each of the phosphor layers to emit light and projecting an image.
この種のカラー受像管では、良好な色再現を行なうため
に、シャドウマスクＩＯの多数の電子ビーム通過孔９と
これらの電子ビーム通過孔９のそれぞれに対応する３色
の蛍光体層との相対位置を、電子ビーム通過孔９を通過
した電子ビーム５が所定の蛍光体層に正確にランディン
グするように、所定の整合関係を保持するようにしてい
る。In this type of color picture tube, in order to achieve good color reproduction, the relationship between the large number of electron beam passing holes 9 of the shadow mask IO and the three color phosphor layers corresponding to each of these electron beam passing holes 9 is determined. The positions are maintained in a predetermined matching relationship so that the electron beam 5 that has passed through the electron beam passage hole 9 will accurately land on a predetermined phosphor layer.
ここで電子ビーム５のランディングは、地磁気等の外部
磁界の影響を受けると、再生画像の色純度が劣化する。Here, if the landing of the electron beam 5 is affected by an external magnetic field such as earth's magnetism, the color purity of the reproduced image will deteriorate.
このため、シャドウマスク慣体８にファンネル３の内面
に沿って延在する磁性体金属板からなる磁気シールド体
１３を取付けている。For this reason, a magnetic shield body 13 made of a magnetic metal plate is attached to the shadow mask inert body 8 and extends along the inner surface of the funnel 3.
そして、この磁気シールド体ｌ３としては、たとえば、
特公昭６３−６７３０７号公報に示されるようなものが
多く用いられている。すなわち、外部磁界を完全にシー

界によるミスランディングを防止するようにしている。And, as this magnetic shield body l3, for example,
The one shown in Japanese Patent Publication No. 63-67307 is often used. That is, since it is difficult to completely shield the external magnetic field, mislanding due to the external magnetic field is prevented by changing the shape, material, etc. of the magnetic shielding body 13, shadow mask structure 8, etc.
しかし、近年のカラー受像管では、画像の高画質化、高
品位化に伴い、高い解像度特性が要求されている。この

ッチを小さくする必要があり、ランディングエラーが生
じやすくなる。特に、画面周辺部では、ビーム偏向角の
増大に伴い、外部磁界によるランディング移動量が大き
い。However, in recent years, color picture tubes are required to have high resolution characteristics as images become higher in quality and quality. For this reason, it is necessary to reduce the pitch between the many phosphor layers in the phosphor screen 7, making landing errors more likely to occur. In particular, at the periphery of the screen, the amount of landing movement due to the external magnetic field increases as the beam deflection angle increases.
このように、高画質化、高品位化のために蛍光体層のピ
ッチの小さいカラー受像管では、特に画面周辺部におい
て外部磁界によるランディング移動屋が大きく、前記従
来の磁気シールド体！３によっても完全に改善させるこ
とは困難である。As described above, in color picture tubes in which the pitch of the phosphor layers is small in order to achieve high image quality and quality, the landing movement caused by the external magnetic field is large, especially in the periphery of the screen. Even with 3, it is difficult to achieve complete improvement.

界の磁束Ｉ６． １７が集中し、磁界が乱れる現象が生
じる。There are several causes of such landing errors due to external magnetic fields at the periphery of the screen, but one of the main causes is disturbance of the magnetic field at the periphery of the opening l4 on the electron gun 6 side of the magnetic shield I3. be. That is,
Figure 5 shows the magnetic flux 16 of the external magnetic field in the direction perpendicular to the tube axis (center axis) l5, and Figure 6 shows the magnetic flux 17 of the external magnetic field in the direction parallel to the tube axis l5. Since I3 is formed of a magnetic metal plate, the magnetic flux I6 of the external magnetic field is generated near the periphery of the opening 14 on the electron gun 6 side. 17 is concentrated, causing a phenomenon in which the magnetic field is disturbed.
このため、特に、開口部１４の周縁付近を通過する偏向
角の大きな電子ビーム５は、この磁界の乱れにより相対
的に大きなローレンツカを受け、ビーム軌道が変化する
。これにより、特に画面周辺部において局部的に大きな
ランディングエラーが生じる。Therefore, in particular, the electron beam 5 having a large deflection angle that passes near the periphery of the opening 14 is subjected to a relatively large Lorentz force due to the disturbance of this magnetic field, and the beam trajectory changes. This causes a locally large landing error, especially in the periphery of the screen.

域でのランディングエラーが増大し、好ましくない。The opening l of such a magnetic shield body 13 on the electron gun 6 side
In order to eliminate disturbances in the magnetic field at the periphery of the opening 14 and reduce landing errors at the periphery of the screen, the opening 14 should be made larger to move the periphery of the opening 14 away from the passing position of the electron beam 5. In this case, the effect of shielding the external magnetic field by the magnetic shield 13 is reduced, and landing errors across the entire screen are increased, which is not preferable.

肛以上が適当である。In FIG. 3, the magnetic shielding body 13 is integrally formed with a magnetic metal plate into a substantially truncated pyramid shape, and has a frame-shaped mounting side that engages with the inner surface of the mask frame 11 of the shadow mask structure 8. 21, an edge 22 parallel to the tube axis (center axis) 15 is bent on the outside of the attachment side 21, and a slope 23 along the inner surface of the funnel 3 is formed on this edge ridge 22. A curled portion 2 is provided in series and bent outward in an arc shape at the periphery of the opening l4 of the slope portion 23 on the electron gun 6 side.
4 are provided. The radius of curvature of this curled portion 24 varies depending on the size and deflection angle of the color picture tube, but for example, in a 32-inch color picture tube with a 110° deflection, the radius of curvature is approximately 2.

It extends in six directions.

Fig. 3 shows the magnetic flux l6 of the external magnetic field in the direction perpendicular to the tube 1dll5, and the magnetic flux l7 of the external magnetic field in the direction parallel to the tube 1dll5.
Due to the outward curling portion 24 at the periphery of the opening 14, the magnetic flux 1B, IT of the external magnetic field near the periphery of the opening 14 has a gentle distribution, and the opening as shown in FIGS. No disturbance of the magnetic field near the periphery of the magnetic field 14 occurs.

As a result, the electron beam 5 having a large deflection angle that reaches the periphery of the screen is not affected by disturbances in the external magnetic field, and landing errors are significantly reduced.
