この考案は螢光表示管に関し、特に高密度のプ
リントを必要とするドツト表示用基板の製作に有
効な構造に関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a fluorescent display tube, and particularly to a structure effective for manufacturing dot display substrates that require high-density printing.
以下図面を参照しながら説明する。 This will be explained below with reference to the drawings.

プリント精度の観点から2層以上の絶縁層を形成
した方が製造し易い。すなわち、プリント線間を
狭くし、線幅を細くすること、シヨートや断線が
多発し、歩留が低下する。 FIG. 1 shows a partially cutaway perspective view of a fluorescent display tube with a 5.times.7 dot display. That is, for example, the airtight container 1 along with the exhaust pipe 1 and the cover glass 2
For example , as shown in FIG .
The filament supports 6 1 , 6 2 (not shown) are formed by forming dot display electrodes of phosphor in the format and feeding power from external power supply terminals 8 1 , 8 2 , . . .
In the meantime, the electrons emitted from the suspended filaments 7 1 , 7 2 are accelerated and controlled by the grits 5 1 , 5 2 , and so on and impact the dot display electrodes to select alphabets, kana letters, numbers, symbols, etc. When using the thick film printing method, when the distance between the displayed dots is 1.2 mm or less for a fluorescent display tube that displays
From the viewpoint of printing accuracy, it is easier to manufacture if two or more insulating layers are formed. That is, by narrowing the distance between printed lines and making the line width thinner, shots and wire breaks occur frequently, resulting in a decrease in yield.
そこで、プリントの工程毎に基板を点検するこ
とが必要になる。 Therefore, it is necessary to inspect the board at each printing process.

でなく、検査端子を作るのにも複雑となる。 In the conventional configuration, wiring was performed as shown in Fig. 3. In order to electrically detect this, the points connecting the external power supply terminals 8 1 , 8 2 , ... and the dot display electrodes (usually , 9 1 , 9 2 , ..., 9 8 (hereinafter referred to as through holes) need to be contacted with the terminals of the equipment that inspects shorts and disconnections, but the through holes are usually as thin as the wiring width. Because of this requirement, not only can it be destroyed by mechanical contact, causing shorts or disconnections, but it is also complicated to make test terminals.
この考案の目的は、第4図に示すように検査専
用の端子101,102,…,108を設けること
により従来の配線構成による上記問題点を解決す
る螢光表示管を提供することにある。 The purpose of this invention is to provide a fluorescent display tube that solves the above-mentioned problems caused by the conventional wiring configuration by providing terminals 10 1 , 10 2 , . . . , 10 8 exclusively for inspection as shown in FIG. It is in.

を特徴とする螢光表示管が得られる。 According to the present invention, glass forms a power supply line, an insulating layer, a base electrode, a display electrode, etc. on an insulating substrate such as ceramic, and forms part of the envelope of a vacuum-tight container containing a filament, a grid, etc. A fluorescent display tube is obtained, which is characterized in that a terminal is provided at a point on the power supply line connected to the display electrode or at a point other than the external power supply terminal.
以下に第4図を参照して本考案の一実施例を説

08が外部給電端子から最も離間した位置で従来
の給電線に新たに付加されている。 Figure 4 shows the substrate of a fluorescent display tube, in which a power supply line printed with silver, an insulating layer made of glass, a base electrode made of graphite, etc. are formed on an insulating substrate made of glass or ceramic, and display electrodes made of phosphor are formed. This shows the power supply line structure, and shows an example of a dot display board that requires particularly high-density printing .
08 is newly added to the conventional power supply line at the farthest position from the external power supply terminal.
すなわち、検査端子101,102,…,108

することができる利点もある。 That is, the test terminals 10 1 , 10 2 ,..., 10 8
is a valid terminal only for this printed layer, so
Even if a product is destroyed during inspection, it is covered with an insulating layer in the next process to eliminate its function, or is left completely unattended, so not only does it not cause problems like in the past, but it can also be inspected in areas that are easy to inspect. Another advantage is that it can be easily formed into an array.
