To provide a measuring instrument with which it is possible to suppress the blur of the contour of an area that lights up.SOLUTION: A measuring instrument 1 comprises a nameplate 5, a light limiting member 41, an adhesive member 8, and light sources 13, 15, 17. The nameplate includes a permeable area 35 which light can pass through. The light limiting member is arranged closer to the rear side than the nameplate and does not pass light through as easily as the permeable area. The adhesive member adheres the nameplate and the light limiting member together. The adhesive member does not pass light through as easily as the permeable area. First holes 43, 45, 47 constituting a portion of an optical path leading from the light sources toward the permeable area are formed in the light limiting member. Second holes 59, 61, 63 constituting a portion of the optical path are formed in the adhesive member. When seen from the plate thickness direction of the nameplate, the second holes are smaller than the first holes and are included in the first holes.SELECTED DRAWING: Figure 2
【課題】点灯する領域の輪郭がぼやけてしまうことを抑制できる計器を提供すること。【解決手段】計器1は、文字板5と、光制限部材41と、接着部材8と、光源13、15、17とを備える。文字板は、光が透過可能な透過領域35を有する。光制限部材は、文字板よりも背面側に配置され、透過領域よりも光を透過させにくい。接着部材は、文字板と光制限部材とを接着する。接着部材は、透過領域よりも光を透過させにくい。光制限部材に、光源から透過領域に向かう光路の一部となる第1孔43、45、47が形成されている。接着部材に、光路の一部となる第2孔59、61、63が形成されている。文字板の板厚方向から見たとき、第2孔は、第1孔より小さく、第1孔に含まれる。【選択図】図2
