この考案は、平板状のデジタル表示管を用いて収るデジ
タルタイマーやデジタルテスター等の表示装置に係り、
特に前面パネル板に穿設した表示窓に平板状のフィルタ

部の部品が不必要に見えるのを抑制する構造に関するも
のである。[Detailed description of the invention] This invention relates to display devices such as digital timers and digital testers that use a flat digital display tube.
In particular, it relates to a structure that allows a flat filter to be tightly fixed to a display window drilled in a front panel plate with a simple operation without distorting the filter, and that prevents parts inside the main body from being unnecessarily visible from the outside through the filter. It is something.
従来の前面パネル板に穿設した表示窓をその内方側から
フィルター53で閉塞してなる表示装置では(第4図参
照)、フィルター53は表示窓52の枠部に直接接着剤
で接着あるいはネジ54により締付は固定されていた。In a conventional display device in which a display window formed in a front panel plate is closed from the inside with a filter 53 (see FIG. 4), the filter 53 is directly attached to the frame of the display window 52 with adhesive or Tightening was fixed by screws 54.
しかし前者の接着剤による接着では一度取付は固定され

4図に示すようにフィルター53がネジ54の締付位置
付近で変形し、表示管(図示せず)からの光線が局部的
に歪んで屈折され表示文字が不鮮明になるうえに、表示
窓の寸法誤差によりフィルターを通して外部からケース
内の他の部品が見えるという欠点があった。However, with the former method of adhesive bonding, once the installation is fixed, not only is it impossible to replace the defective product due to damage, etc.
There is a disadvantage that the adhesive protrudes from the frame part during adhesion, making it difficult to assemble, and the latter method of fixing with the screws 54 is difficult to work with and is expensive, and since the filter 53 is plate-shaped and long, the screws 54 are difficult to assemble. If the tightening strength is not properly controlled, a gap will be created and the filter 53 will become loose, and if it is over-tightened, the filter 53 will be deformed near the tightening position of the screw 54, as shown in Figure 4, and the display tube ( In addition, light rays from the casing (not shown) are locally distorted and refracted, making the displayed characters unclear, and due to dimensional errors in the display window, other parts inside the case can be seen from the outside through the filter.

を防止するものである。In order to solve the above-mentioned drawbacks, this invention provides a pair of opposing standing walls protruding from the upper and lower parts of the front panel board, a display window is bored on the upper side between these standing walls, and the lower periphery of the window is The lower end of the flat filter is secured to the recessed step provided in the cross section.
With the notch on one side of the letter-shaped mounting bracket in contact with the longitudinal end surface of the upper end of the filter, install and position the mounting bracket on the upper vertical wall, and then insert the tongue piece from the middle side of the mounting bracket. vertically to position the rear surface of the filter, and then fix the printed circuit board to the other side of the mounting bracket and the lower standing wall parallel to the front panel board to cover the rear surface of the filter. The letter-shaped mounting bracket allows for easy positioning of the flat filter without distorting it, and this same mounting bracket can also be used as a member to fix the printed circuit board parallel to the panel board, and also to fix the printed circuit board in parallel. By doing so, the rear side of the filter is covered and the internal structural components of the device are prevented from being unnecessarily transmitted through.
