Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は可変抵抗装置に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a variable resistance device.
Ｕ従来の技術］
従来、抵抗値の可変範囲が大きく、しかも微調整のきく
ものに、いわゆる多回転型の可変抵抗器がある。これは
、ネジを切った回転軸を回転させることによって抵抗体
上を摺動子を摺動させて調整を行うものである。U. Prior Art] Conventionally, there is a so-called multi-rotation type variable resistor that has a wide variable range of resistance value and can be finely adjusted. This adjustment is performed by rotating a threaded rotating shaft to slide a slider on the resistor.
［発明が解決しようとする問題点］
上記のものでは、調整時間が短くしかも微調整がきくと
いう２つの条件をともに満足させることはできなかった

整を優先してしてつまみが緩かに回転するようにすると
、調整に時間がかかるというものであった。[Problems to be Solved by the Invention] The above-mentioned method cannot satisfy the two conditions of short adjustment time and fine adjustment. In other words, if you prioritize the adjustment time and make the knob turn quickly, fine adjustment will not go well; conversely, if you prioritize fine adjustment and make the knob rotate slowly, it will take longer to make the adjustment. It was said that it would cost.
本発明は、調整時間が短くてすみ、しかも微調整が簡単
に行える可変抵抗装置を提供するものである。The present invention provides a variable resistance device that requires less adjustment time and allows fine adjustment to be performed easily.

The sliding speed of the slider changes as the knob rotates.

The screws are cut. 3 is a slider that slides on the resistor 4 as the rotating shaft 1 rotates. 5 is a large diameter gear for rapid feed of the slider 3, and 6 is a small diameter gear for fine adjustment. 7 is a transmission gear, and 8 is a gear fixed to the shaft of the knob 9. 1
0 is a spring that pushes down the gear 8 to mesh with the gear 7.

軸２は上記より低速で回転し、微調整が行えるのである
。In the above configuration, when making coarse adjustments, use the knob 9.
Rotate as shown. This rotation is transmitted to gear 6 via gear 7, and shaft 2 is rotated at a relatively high speed. Therefore, the slider 3 slides quickly, and the resistance value is roughly adjusted to a value close to the desired resistance value. Then, the knob 9 is pushed in, the gear 8 meshes with the gear 5, and the knob 9 is rotated. therefore,
The shaft 2 rotates at a slower speed than above, allowing fine adjustments to be made.
