Abstract

PURPOSE: To constitute a safety device which covers a whole body of an unattended cart by a movable member which is movably supported within a level surface and a detecting body provided on the movable member.
CONSTITUTION: When an obstacle 22 touches a bumper F15, the bumper turns counter-clockwise around a roller 14-b, and optical paths of a photoelectric switch 20-a and a photoelectric switch 20-b are displaced and a reflection band 21-a and a reflection band 21-b become undetectable, so that the obstacle 22 can be detected. When another obstacle 23 comes close to a side surface of an unattended cart 3, the optical path of the photoelectric switch 20-a is interrupted and the switch 20-a becomes unable to detect the reflection band 21-a, so that the obstacle 23 can be detected.
