(57) [Summary] [Objective] Conventionally, there was a caliper as a measuring instrument for measuring precise dimensions, but the scale 4 engraved on the main scale 3 and the vernier scale 6 engraved on the vernier 5 were used. It was so precise and detailed that it was not easy to check the scale for people with weak eyesight or presbyopia, so I used a magnifying glass to check the matching points on the scale. [Structure] The vernier caliper to which this invented scale magnifying lens is attached is as shown in FIG. 1 in which a lens fixing frame 8 is provided on the vernier 5 so that the coincidence point of the scale can be easily confirmed by the magnifying lens 9. It is a vernier caliper.
Description
精密に物の外径や内径を測る為の計測器ノギス。 A caliper measuring instrument for precisely measuring the outer and inner diameters of objects.
【０００１】[0001]
従来精密な寸法を測る為の計測器にノギスが在ったが、図１に示すように外径 計測用１又は内径計測用２により、測った寸法は本尺３に刻まれた目盛り４と バーニャ５に刻まれた副尺目盛り６の合致点を読み取る事により物の寸法を計 測していた。 Conventionally, there was a caliper in measuring instruments for measuring precise dimensions, but as shown in Fig. 1, by measuring 1 for outer diameter or 2 for inner diameter measurement, the measured dimensions are the scale 4 engraved on the main scale 3. The size of the object was measured by reading the matching points on the vernier scale 6 engraved on the vernier 5.
【０００２】[0002]
前項に於いての本尺３に刻まれた目盛り４とバーニャ５に刻まれた副尺の目盛 り６が大変精密で細かい為に視力の弱い人や老眼になった人には目盛りを確認 するのが容易では無い為に虫メガネ等を使用して目盛りの合致点を確認してい たが。 The scale 4 engraved on the main scale 3 and the scale 6 on the vernier scale engraved on the vernier 5 in the previous section are so precise and detailed that they should be checked for people with weak eyesight or presbyopia. Since it is not easy to do, I used a magnifying glass to check the matching points on the scale.
【０００３】[0003]
この考案した目盛り拡大視レンズを取り付けたノギスはバーニヤ５にレンズ固 定枠８を設け拡大視レンズ９により目盛りの合致点を容易に確認する事が出来 る要にしたノギスである。 The vernier caliper to which the graduated magnifying lens of the present invention is attached is a vernier caliper in which a lens fixing frame 8 is provided on the vernier 5 so that the matching point of the graduation can be easily confirmed by the magnifying lens 9.
【０００４】[0004]
この考案した目盛り拡大視レンズを取り付けたノギスは拡大視レンズ９により 目盛りの合致点を容易に確認する事が出来るので。 With the magnifying lens 9, the caliper to which this devised scale magnifying lens is attached can easily confirm the matching point of the scale.
【０００５】[0005]
従来のノギスを使用していた時のように、視力の弱い人や老眼になった人は眼 鏡を掛けたり虫メガネ等を使用して精密で細かい目盛りの合致点を確認するの に容易ではなかったが目盛り拡大視レンズを取り付けたこのノギスは片手で目 盛りの合致点を簡単に正確に確認する事が出来るノギスである People with weak eyesight or presbyopia, such as when using conventional vernier calipers, cannot easily check the precise and fine matching points of the scales by using an ophthalmoscope or magnifying glass. This caliper, which was not equipped with a scale magnifying lens, is a caliper that allows you to easily and accurately check the matching point of the scale with one hand.
