This creation is related to a kind of industrial introscope scale bar structure,It is by one with visualization unit processing host,One transfer tube and a camera lens,The transfer tube both ends are separately connected the processing host and the camera lens,The characteristic of this creation matches the measurement group formed with the probe for setting up camera lens separately by the ruler plate that plural number sets up visualization unit separately in what,And respectively the ruler plate surface has a Scale,And respectively the Scale specification of the ruler plate respectively corresponds matching probe length,Thereby,Enable introscope utilize matched as probe with ruler plate made of measurement group,And can use in groups,Electronic type is not had because of misalignment caused by handoff error and inconvenient,Simultaneously can general precision require when,There can be reduction purchasing price,To improve the competitiveness of entirety.本創作涉及一種工業用內視鏡比例尺結構，其係由一具有顯像單元之處理主機、一傳輸管及一鏡頭，該傳輸管兩端分別連接該處理主機與該鏡頭，本創作的特色在於由複數分設顯像單元之尺板與分設鏡頭之探針所匹配組成的量測組，且各該尺板表面具有一刻度尺標，而各該尺板之刻度尺標規格分別對應與之匹配的探針長度，藉此，使內視鏡能利用由探針與尺板所匹配而成的量測組，而能成組運用，不會有電子式因切換錯誤所造成的失準與不便，同時能在一般精度要求時，可以有降低購買價格，從而提高整體之競爭力。
