。By the way, a uniform magnetic field is generally known as a deflection magnetic field with little deflection distortion. FIG. 6 shows the effective screen and its beam spot when the horizontal and vertical deflection magnetic fields of the above-mentioned beam index type color picture tube are made into uniform magnetic fields. In this Fig. 6, the beam spot S at the center of the screen
1. Beam spot S2 located at the left and right edges of beam spot S1 and beam spot S3 located at the upper and lower edges of beam spot 31 have their respective longitudinal directions parallel to the Y-axis direction. Although the widths at, a2, and a3 in the Y-axis direction (hereinafter referred to as vertical widths) are approximately equal, the beam spot S4 located at the corner of the screen is tilted diagonally with respect to the Y-axis direction, and its vertical width Width a4 and width b4 are each beam block 1
-31, the vertical width a1 and the horizontal width b1 were wider.

るものを提案せんとするものである。Therefore, at the corners of the screen, the beam spot S4 is tilted with respect to the Y-axis direction as shown in Figures 6 and 7, so the width increases with respect to the color phosphor stripes B1R and G. For example, when the beam switch 1-34 is striking the red phosphor stripe R, it will also strike the blue and green phosphor stripes B and G, and in addition to the red, the blue and green phosphor stripes will also be struck. It had the disadvantage that it emitted light and its color purity deteriorated. - In view of these points, the present invention proposes a device that can obtain a vertically elongated beam spot over the entire screen and can obtain an image with high color purity.

ける磁界が斉一となることが望ましい。First, in the horizontal deflection coil, a bottle cushion magnetic field is effective as a deflection magnetic field in order to make the beam spot S4 at the corner of the screen stand in the Y-axis direction. In this case, the second
As shown in the figure, the widths a2 and a4 of the beam spots S4 and S2 at the corner and the upper edge of the X axis are wider than the width a1 of the beam spot Sl at the center of the screen, so that there is no so-called landing allowance. Also, the vertical widths b4 and b2 of the beam spots S4 and S2 are the vertical width b of the beam spot Sl.
It will be shorter than 1. Also, the neck side of the deflection yoke is effective for focusing the beam spot, and the so-called hot tilt of the beam spot is more effective at the aperture side. In order to make the electron beam stand upright, as shown in Figure 3, the deflection magnetic field on the neck side is made into a barrel magnetic field, and the deflection magnetic field on the opening side is made into a bottle cushion magnetic field, so that the magnetic field received by the electron beam as a whole becomes uniform. desirable.

In this way, when the vertical deflection magnetic field is a binkutsushiron magnetic field, the vertical widths b4 and b3 of the beam spots S4 and S3 at the corners and the upper edge of the Y axis are equal to the vertical width bl of the beam spot 31 at the center of the screen, as shown in FIG. becomes longer than
The widths a4 and a3 of the beam spots S4 and S3 are narrower than the width a1 of the beam spot S1.

Also, the strength of the magnetic field of the horizontal deflection coil H of the horizontal deflection yoke is determined by the vertical width of the beam spot on the 75-1 of bl
00% and the strength of the magnetic field of the vertical deflection coil V is determined by changing the vertical width b1 of the beam spot Sl at the center of the screen to the vertical width b1 of the beam spot on the Y axis at a position of 90% of the effective screen. In other words, the window width W1 on the opening side of the horizontal deflection coil H is set to a predetermined time, for example, 3 to 4 times, compared to the window width W2 on the neck side, and the vertical deflection of the vertical deflection yoke is adjusted so that the length is 100 to 135%. The window width W3 on the opening side of the coil V is set to a predetermined times, for example, 3 to 4 times the window width W4 on the neck side.
Multiply it by 5 times.

18) Sony Corporation Representative Director Norio Ohga 4, Attorney 6, number of inventions increased due to amendment (11 In the specification, the name of the invention is corrected to "Deflection device for color picture tube". (2) Same as above) The claims are amended as shown in the attached sheet. (3) Same, page 1, line 17, page 1, line 20, page 2, line 13, page 4, line 15, page 5, line 15, page 11. The words "color picture tube" in line 20 and line 4 on page 12 are corrected to "deflection device for color picture tube".In the above claims, in a color picture tube designed to obtain a vertically elongated beam spot, The deflection yoke and the vertical deflection yoke are respectively configured in a saddle shape such that a barrel magnetic field is obtained on the neck side and a bottle cushion magnetic field is obtained on the opening side, and the window width on the opening side of the horizontal deflection coil of the horizontal deflection yoke is set as above. The width of the window on the opening side of the vertical deflection coil of the vertical deflection yoke is made a predetermined times larger than the width of the window on the neck side. Features a color picture tube and anal illumination
