The structure of the entire color sorting apparatus is the same as that of the conventional color sorting apparatus shown in FIG. Therefore, the description will be omitted and the holder part will be described. Reference numeral 4 denotes a plate-like holder for attaching and holding the color selecting device inside the tube of the color cathode ray tube, which is attached by electric welding to each of the opposite sides 1A and 1B on which a large number of filaments 10 of the frame 1 are stretched. ing. This plate-shaped holder 4 is composed of two elongated plates 4
a and 4b are integrated by welding so as to form an "L" shape. One plate 4a of the holder 4 is made of bimetal, and its ends are opposite sides 1A, 1B of the frame 1.
Is electrically welded to each outer side of the welding regions 8a and 8b which form a pair along the extending direction of the frame 1. The other elastic plate 4b is attached to the free end of the plate 4a by welding. A through hole 4c is formed in the other plate 4b.

１１を設ける。In this embodiment, the plate 4a of the plate holder 4 is
Outside the opposite sides 1A and 1B of the frame 1 of the opposite side 1
Although the welding is performed with two even welded areas 8a, 8b substantially along the extending direction of A, 1B, between the welded areas 8a, 8b paired with the opposite sides 1A, 1B of the frame 1,
The length L in the direction substantially orthogonal to the direction connecting the paired welding regions 8a and 8b is such that the paired substantially circular welding regions 8 are formed.
A cutout 11 is provided, that is, a cutout portion 11a, 8b longer than the diameter Φ.

くなり、カラー画像の画質低下は生じ難くなる。By providing the notch 11 as described above, when the holder 4 is electrically welded to the opposite sides 1A, 1B of the frame 1, the current flowing between the frame 1 and the holder 4 becomes smaller than that in the conventional example. Therefore, heating of the opposing side of the frame 1 in the vicinity of the mounting portion of the holder 4 of the frame 1 is less than in the conventional example, and the tension of the filament 10 in the vicinity is less likely to decrease. Further, since the notch 11 is provided in the holder 4, that is, the plate 4a, the holder 4, that is, the plate 4a,
Since the rigidity of the plate 4a is reduced, the material of the frame 1 is less likely to deteriorate in the heat treatment process of the color cathode ray tube as compared with the conventional example, and the tension of the filament 10 near the mounting portion of the holder 4 is less likely to be reduced. . Therefore, as is clear from the curve T 2 in FIG. 5, the tension of the filament 10 in the vicinity of the plate-shaped holder 4 on the opposite sides 1A, 1B of the frame 1 is less likely to decrease, and the image quality of the color image is deteriorated. Is less likely to occur.

In, the plate-shaped holder for mounting and holding the color selecting device in the tube body of the color cathode ray tube is a color selecting device which is attached by electric welding, respectively,
Since a notch (a notch or a through hole) extending in a direction substantially orthogonal to a direction connecting the paired welding regions is provided between the paired welding regions with respect to the opposite sides of the frame, the notch satisfies the above-mentioned condition. At the time of electric welding, the current flowing between the opposing sides of the plate-shaped holder and the frame is reduced, the heating of that portion is reduced, and the tension of the filaments in the vicinity is less likely to decrease. In addition, since the rigidity of the plate-shaped holder near the frame mounting portion is reduced, the material of the frame is less likely to deteriorate during the heat treatment process of the color cathode ray tube, and the tension of the filament near the plate-shaped holder mounting portion is less likely to be reduced. Therefore, it is possible to obtain a color selecting device in which the deterioration of the image quality of the screen of the color cathode ray tube due to the partial decrease in the tension of a large number of filaments is improved. According to the color cathode ray tube of the second aspect of the invention described above, by including the color selecting apparatus of the first aspect of the invention, the deterioration of the image quality of the screen due to the partial tension reduction of a large number of filaments in the color selecting apparatus is improved. It is possible to obtain a color cathode ray tube.
