    摘要： At both sides of a pair of doors 10L, 10R, a pair of television cameras (two-dimensional image sensors) 18A, 18B for detecting a moving object, and a pair of spare infrared ray sensors 20A, 20B are provided. A central control unit 16 calculates the position and moving direction of moving object by image processing of outputs of television cameras 18A, 18B, and predicts the passing position of moving object on the vertical plane P when the moving object approaches, thereby calculating the target opening degree of a pair of doors 10L, 10R individually, and determines the target opening degree of doors in full closing when the moving object leaves away, and thus outputs move command signals to motor controllers 14L, 14R so that the pair of doors 10L, 10R may be set at the target opening degree.

    摘要： A spacer for a linear motion apparatus (1) is to be interposed alternately between balls arranged in an endless circulation passage of the linear motion apparatus (1). The spacer has a body portion comprising spherical retaining surface portions formed for supporting the balls (4) on both end portions thereof in an advancing direction of the spacer when moving in the endless circulation passage and a circumferential surface portion constituting an outer peripheral portion of the spherical retaining surface portions. The spherical retaining surface portion has a radius of curvature smaller than a diameter of the ball and the circumferential surface portion is provided with a groove extending in the circumferential direction thereof so that one of the spherical retaining surface portions is elastically deformable towards another one thereof. The spacer is preferably applicable to various kinds of linear motion apparatus. Further, rollers as rolling members may be utilized in place of the balls.
