<p>PROBLEM TO BE SOLVED: To restrain device constitution from becoming complicated by fitting a guide rail with detected bodies with the upper face side or lower face side as detected faces to be detected by detecting sensors provided at an article carrier. SOLUTION: A guide rail 8 is formed by connecting a plurality of rail parts 8a. A lateral pair of recessed grooves 82 extended along the longitudinal direction or the guide rant 8 are formed in the lateral end side positions of the upper face of the guide rail 8, and bolt-like magnets 47 are fitted into the recessed grooves 82, in the posture with the vertical direction as the direction of the magnetic field. A lateral pair of magnetic sensors 48, detecting sensors for the magnets 47 to be detected bodies ST, are provided in the rear end position of a support body 36 on the body rear side, in correspondence with a lateral pair of magnets 47. Each magnetic sensor discriminatingly detects a magnetic pole of N-pole or S-pole appearing on the upper face of the magnet 47 with the upper face of the magnet 47 as a detected face.</p> |
