    • PROBLEM TO BE SOLVED: To significantly improve the measurement accuracy at low cost while reducing an independent optical part as much as possible.
      SOLUTION: In this encoder, two interferable lights 20 and 21 emitted from both end surfaces of a semiconductor laser 16 are incident on a diffraction grating in a scale 2 having the diffraction grating 23 formed thereon, diffracted lights of the two lights diffracted by the diffraction grating are mutually interfered to detect the light intensity of the interfered light, and the signal of the light intensity is outputted as a signal corresponding to the moving quantity of the scale. The thickness direction of an active layer 32 of the semiconductor laser within a plane orthogonal to the propagating direction of the lights emitted from both end surfaces of the semiconductor laser 16 is matched to the moving direction of the scale at the time when the lights are incident on the scale 22.

    • A stroke sensor has two magnets, which are magnetized in a cross-section direction and are displaced in a longitudinal direction, and two magnetism sensitive sections arranged parallel to the longitudinal direction. The magnets have circular-arc-shaped swelling end edges respectively and are magnetized such that the swelling end edges have opposite polarities. Thus, a distribution of a magnetic flux density on an arrangement axis substantially coincides with a sine curve. The magnetic flux having such the distribution is displaced in the longitudinal direction together with the magnets. The magnetism sensitive sections are arranged on the arrangement axis to be distant from each other by a distance of one fourth of a cycle of the sine curve. Thus, the stroke sensor that is not affected by temperature and that has high sensing accuracy can be provided.
    • 行程传感器具有两个在横截面方向被磁化并沿纵向位移的磁体和两个平行于纵向排列的磁感应部分。 磁体分别具有圆弧形的膨胀端边缘并被磁化,使得膨胀端边缘具有相反的极性。 因此,布置轴上的磁通密度的分布基本上与正弦曲线一致。 具有这种分布的磁通与磁体一起在纵向方向上移位。 磁感应部分布置在布置轴上,以相对于正弦曲线的周期的四分之一的距离彼此远离。 因此,可以提供不受温度影响并且具有高感测精度的行程传感器。
