問題があつた。 However, with recent commercialization trends, as displays have become larger, panels have also become larger, and longer filaments for emitting electrons have been used. In a fluorescent display tube using a long filament, a suspension 9 as shown in Fig. 8 is used to prevent vibration of the filament, but supports 9 and 10 are required to fix the suspension 9. The fixing supports 9 and 10 require extra internal space, which inevitably increases the external dimensions of the fluorescent display tube. The external dimensions may be limited due to the usage set of the fluorescent display tube, and it is unavoidable that the spacer glass component is used.1
In some cases, it may be necessary to reduce the thickness of 2 and 12' and increase the inner dimensions of the spacer glass, resulting in the problem that strength and reliability must be sacrificed accordingly.
本考案の蛍光表示管は、第１図に示す様にフイ

ラス第５図の７を得ることができる。 Figure 1 shows an embodiment of the present invention, with the short side dimension 40.
mm, indicating a fluorescent display tube with long side dimension 250 mm. A phosphor 2 is coated on an anode substrate 1 in a predetermined pattern, and a grid 3 for controlling electrons emitted from a filament 4 is provided on the phosphor 2. The filament 4 is prevented from vibration by a suspension 8, which is fixed by supports 9,10. The spacer glass 7 has supports 9 and 10
A recess 11 is provided at a position corresponding to the supports 9, 1.
It is designed so that 0 does not touch. The spacer glass 7 is made using a carbon mold shown in FIG. The carbon mold has a lower mold provided with a groove 12 into which a glass piece 15 is inserted according to the dimensions of the spacer glass 7, protrusions 13, 13' corresponding to the recesses 11 of the spacer glass 7, and guide pins 14, 14' of the upper mold. It consists of an upper mold 16 that presses a piece of glass 15. Set the glass pieces 15 as shown in Figure 3 (four pieces of glass are set, but their illustration is omitted) 1000
By heating the glass piece to 0.degree. C. to melt the glass piece and pressing it with an upper mold 16 as shown in FIG. 4, a spacer glass 7 in FIG. 5 having a recess 11 can be obtained.

As explained above, in the present invention, by providing the recess 11 in a part of the inner side of the spacer glass 7, the spacer glass 7 does not come into contact with the supports 9, 10 of the suspension 8, and has sufficient strength. This provides a highly reliable fluorescent display tube.
