Claims

[Claims for Utility Model Registration] 1. In a device for detecting whether or not the moving object is stopped at the exit of a moving object conveying device that transports the moving object along a predetermined direction of travel to the exit. , a plurality of photoelectric sensors provided at predetermined height positions above the exit and at predetermined intervals from each other along the traveling direction, and each having an optical axis in a direction substantially perpendicular to the traveling direction; determines whether the optical axis continues to be blocked by the moving object for a predetermined period or more, and when the optical axis continues to be blocked by the moving object for the predetermined period or more; An exit point object stop detection device for a moving object conveyance device, comprising: a determining means for determining that the moving object is stopped at the exit exit. 2. The exit object stop detection device for a moving object transport device according to claim 1, wherein when the moving object is a person, the predetermined height position is a position slightly higher than the ankle of the person. 3. The exit object stop detection device for a moving object transport device according to claim 1, wherein the plurality of photoelectric sensors are attached to handrails provided on both sides of the exit in the traveling direction.
