本考案はスケールの回転角度を容易に読定することがで
きる目盛整合手段を具備する自在平行定規に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a universal parallel ruler equipped with scale alignment means that allows the rotation angle of the scale to be easily read.
従来からヘッド部支持側の分度目盛に対してスケール側
のバーニヤ目盛を突合せてスケールの回転角度を読定す

目盛線の整合位置を読定することは必ずしも容易ではな
く、見やすき、迅速性、正確さの点で問題があり、最近
ではスケールの回転角度をデジタル表示する手段も提案
されるに至っている。Conventionally, there is a known method for reading the rotation angle of a scale by aligning the vernier scale on the scale side with the minute scale on the head support side. It is not always easy to read the scale, and there are problems in terms of visibility, speed, and accuracy.Recently, means for digitally displaying the rotation angle of the scale have been proposed.
しかし、上記デジタル表示手段では、ヘッド部支持側と
スケール側との相対回転部にA−D変換する手段を必要
とし、ヘッド部に大改造を加えなければならないばかり
でなく、大型で複雑な構造を余儀なくされ、実用性の面
で更に多大な技術開発を必要とするのが実情である。However, the above-mentioned digital display means requires means for A-D conversion in the relative rotation section between the head support side and the scale side, which not only requires major modification of the head but also requires a large and complicated structure. The reality is that further technological development is required in terms of practicality.
そこで本考案は従来ヘッド部に構造的に簡単な技術手段

As clearly shown in the figure, an extended degree scale 10b is provided on the outside of the degree scale 10a of the protractor plate 10, while a vernier scale plate 1
1 is made of a transparent member, and its vernier scale 11a is provided at a position where it can overlap the extended minute scale 10b.
従って各バーニヤ目盛11aからは延長分度目盛10b
を透視することができる。Therefore, from each vernier scale 11a, there is an extended minute scale 10b.
can be seen through.
実施例の場合、バーニヤ目盛板11は透明なガラス製の
薄板からなり、バーニヤ目盛11aの目盛線は透明にし
ても不透明にしても良い。In the case of the embodiment, the vernier scale plate 11 is made of a thin plate made of transparent glass, and the scale lines of the vernier scale 11a may be made transparent or opaque.
そして、バーニヤ目盛1aを透明にする場合には目盛線

ある。Incidentally, in the above embodiment, the vernier scale plate 11 is made of a thin plate made of transparent glass, but the point is that it is transparent and has light transmittance so that the degree scale 10b where the bent vernier scale 11a overlaps can be visually recognized. Of course, an alternative material such as a transparent plastic plate or the like may be used.

定するときに特に補強板を必要としない長所がある。In addition, the vernier scale plate 1 is made of a thin metal plate such as stainless steel.
1, it is easy to undergo deformation in terms of strength, so
It is difficult to drill the see-through scale all the way to the edge of the vernier scale 11a, and it is necessary to insert a reinforcing plate when fixing it to the substrate 7, but in the case of the vernier scale plate 11 made of glass or plastic of the present invention, This has the advantage that the vernier scale 11a can be provided up to its edge, and that no reinforcing plate is particularly required when fixing as described above.

る。According to the universal parallel ruler of the present invention having the above configuration, each vernier scale 11a is provided superimposed on the degree scale 10b, so for example in the case of FIG.
Since the vernier scale indicator 0' coincides with 0' and 60', and the minute scale 10b is visible from the vernier scale 11a between 0' and 60', it can be immediately read that the rotation angle of the scale is 06. In the case of Fig. 3, the vernier scale indicator O' is located between 5° and 6° of the minute scale 10a in the counterclockwise direction, and the vernier scale indicator O' is located between 5° and 6° of the minute scale 10a in the counterclockwise direction. Since the scale 10b is visible, it can be immediately read that the rotation angle of the scale is 5°40'.
尚、第3図の場合には、バーニヤ目盛で60′隔てた時
計方向20′のバーニヤ目盛からも分度目盛10bが視
認し得るから、これによって目盛の整合を確認すること
ができる。In the case of FIG. 3, the minute scale 10b is also visible from the vernier scale in the clockwise direction 20', which is 60' apart from the vernier scale, so that alignment of the scales can be confirmed.
尚、バーニヤ目盛のバーニヤ目盛11aの周囲、分度′

Of course, it is also possible to provide the scale 10b and its surroundings with appropriate coloring, fluorescent paint, etc. so that the matched minute scale can be read more easily.

上で極めて効果的である。As described above, according to the universal parallel ruler according to the present invention, the extended degree scale 10b is provided outside the degree scale 10a of the protractor board 10, and as a result, the outer diameter of the protractor board 10 can be increased. Even so, the transparent vernier scale plate 11 overlaps the extended minute scale 10b, and the vernier scale 11a abuts against the inner minute scale 10a, as is the conventional configuration. It is possible to prevent the scale from increasing in size, and the rotation angle of the scale can be read by matching the minute scale 10a and the vernier scale 11a as in the conventional case, and at the same time, it can be seen at a glance by overlapping with the extended degree scale 10b. It has the effect of being easy to read, and is extremely effective in making drafting work efficient and smooth.
