MEASURING INSTRUMENT DEVICE

To provide a measuring instrument device with which it is possible to uniformly illuminate a display board without unevenness in luminance.SOLUTION: A measured value display unit comprises: a base part 71 equipped at least with a display part D21 (display part D2) not located on the optical axis of a light source 11, with a cover part located on the optical axis; and an inside enclosure part 73 (enclosure part) provided so as to enclose the base part 71. In the inside enclosure part 73 are formed an open-hole part 76 designed to allow a first illumination light L1, out of illumination lights L emitted from the light source 11, that leads to the display part D21 (display part D2) via the base part 71 and a surface part P of a circuit board 10 to pass through and a shading part 74a for shading a portion of a second illumination light L2 leading to the display part D21 (display part D2) via the inside enclosure part 73 (enclosure part) and the surface part P.SELECTED DRAWING: Figure 4 【課題】表示板を輝度ムラなく均一に照明することが可能な計器装置を提供する。【解決手段】計測値表示部は、光源１１の光軸上に位置していない表示部Ｄ２１（表示部Ｄ２）を少なくとも備え、覆い部は、光軸上に位置する基部７１と、この基部７１を包囲するように設けられる内側包囲部７３（包囲部）とを有し、内側包囲部７３には、光源１１から発せられる照明光Ｌのうち、基部７１並びに回路基板１０の表面部Ｐを経て表示部Ｄ２１（表示部Ｄ２）へと至る第１照明光Ｌ１を通過可能とした貫通孔部７６と、内側包囲部７３（包囲部）並びに表面部Ｐを経て表示部Ｄ２１（表示部Ｄ２）へと至る第２照明光Ｌ２の一部を遮る遮光部７４ａとが形成されている。【選択図】図４
