A measuring ruler device suitable for measuring a human body posture, comprising a ruler unit, a magnifying glass unit combined with the ruler unit, a detection unit located within the ruler, and a processing unit. The ruler unit includes a ruler body, and an elastic piece located within the ruler body. The ruler body uses the fixation force generated by the deformation of the elastic piece to annularly fasten the human body in performing the operation of posture measurement. In comparison with an artificial annular fastener, the measurement error is significantly improved. After the human body is annularly fastened by the ruler body, the magnifying glass unit will magnify the corresponding gradation digitals for easy viewing. In addition, measurement information is sent through the detection unit to a programmed circuit of the processing unit, in conjunction with a variety of posture determination modes, to allow different users to conveniently and efficiently understand their own postures.一種量測尺裝置,適合用來量測人體體位,包含一尺身單元、一與該尺身單元相結合的放大鏡單元,及位於該尺身單元內的一偵測單元和一處理單元。該尺身單元包括一尺體,及一位於該尺體內的彈性片。該尺體藉由該彈性片的形變所產生的固定力道來環束人體做量測體位的動作,和人工環束相比,量測誤差明顯改善。當該尺體環束人體後,該放大鏡單元將相對應的刻度數字放大以方便觀看。此外,透過該偵測單元將量測資訊送至該處理單元之一程式電路,配合多種體位判斷模式,讓不同使用者方便又有效率地了解自身體位。2‧‧‧尺身單元21‧‧‧尺體211‧‧‧基準端212‧‧‧刻度數字22‧‧‧彈性片3‧‧‧放大鏡單元31‧‧‧鏡座311‧‧‧穿孔32‧‧‧放大鏡4‧‧‧偵測單元41‧‧‧發射器42‧‧‧感測器5‧‧‧處理單元51‧‧‧基座52‧‧‧程式電路53‧‧‧輸出器54‧‧‧儲存模組55‧‧‧警示器56‧‧‧切換按鈕
