The first housing 10 and the second housing 50 may have various shapes and are not The first embodiment of the first housing 10 and the second housing 50 can further be provided with a fixed-length push and twist (to fix the linearly extending ruler line without rewinding) and hooking.

如第四圖,該尺線20可被向外線性延伸(如箭頭a),向外線性延伸之尺線20帶動該軸心15以箭頭A之方向旋轉;向外線性延伸之尺線20若未被定止則可因該自動回捲彈簧之作用而被自動回捲於該軸心15(如箭頭b),自動回轉之尺線20帶動該軸心15以箭頭B之方向旋轉。As shown in the fourth figure, the ruler 20 can be linearly extended outward (as indicated by arrow a), and the linearly extending ruler 20 drives the axis 15 to rotate in the direction of the arrow A; If it is not fixed, it can be automatically rewinded to the axis 15 (such as arrow b) by the action of the automatic rewinding spring, and the automatic rotation of the ruler 20 drives the axis 15 to rotate in the direction of the arrow B.
如第五圖,按著一待測物60之一待測長度65向外線性延伸該尺線20,使該尺線20之扣止件25定止在該待測物60之待測長度65的第一端651,接著,將該尺線20平行或沿著該待測長度65延伸,使尺線20與該出口58的交界處對應於待測長度65的第二端652。As shown in the fifth figure, the ruler 20 is linearly extended outward according to a length 65 to be tested of a test object 60, so that the buckle 25 of the ruler 20 is fixed at the length 65 to be tested of the object to be tested 60. The first end 651, then, extends the ruler 20 parallel or along the length 65 to be measured such that the interface of the ruler 20 and the exit 58 corresponds to the second end 652 of the length 65 to be measured.
如第六圖,當該尺線20被向外線性延伸時,連動該軸心15、轉盤25以及該磁性體30同步旋轉,基於該磁性體30的中心點與該軸心15的中心點對應,因此該磁性體30可直接響應該軸心15的旋轉角度。該磁性體30與旋轉角度感測器40產生相對旋轉關係,旋轉角度感測器40感測磁力大小的變化,同時通過X軸和Y軸座標感測旋轉的方向,從而獲取了該磁性體30的旋轉角度和旋轉方向資訊。As shown in the sixth figure, when the ruler 20 is linearly extended outward, the axis 15, the turntable 25, and the magnetic body 30 are synchronously rotated, and the center point of the magnetic body 30 corresponds to the center point of the axis 15 Therefore, the magnetic body 30 can directly respond to the rotation angle of the axis 15 . The magnetic body 30 is in a relative rotational relationship with the rotation angle sensor 40, and the rotation angle sensor 40 senses a change in the magnitude of the magnetic force while sensing the direction of rotation through the X-axis and the Y-axis coordinates, thereby acquiring the magnetic body 30.

According to the operation method shown in FIG. 5, the length of the ruler 20 extending linearly outward is equal to the length 65 to be tested of the object to be tested 60. Therefore, the tape measure has obtained the specific value of the length 65 to be tested. The microprocessor assembly 45 further converts the linear length into a digital display 55 that is readable by the user and displayed on the tape measure.
捲尺使用方法與習知無異,但通過磁性體30旋轉與旋轉角度感 測器40之感測,將捲尺之軸心旋轉量轉換為捲尺拉線延伸位移量,從而得知一待測物兩點之間的線性距離,所量測的線性距離以可供使用者讀取的數值顯示於捲尺之數位顯示器,解決目視尺線刻度而致誤差或判讀不易的問題,量測結果讀取方便,量測精度高,可靠性高。The method of using the tape measure is the same as the conventional one, but the rotation and rotation angle of the magnetic body 30 are sensed. The sensing of the measuring device 40 converts the axial rotation of the measuring tape into the displacement amount of the measuring tape, thereby knowing the linear distance between two points of the object to be tested, and the measured linear distance is available for the user to read. The numerical value is displayed on the digital display of the tape measure, which solves the problem that the visual scale line scale causes errors or is difficult to read. The measurement result is convenient to read, the measurement accuracy is high, and the reliability is high.
