Claims

[Scope of utility model registration request]

Shine light from a light source onto the floor surface on which guidelines have been laid,
In a self-propelled trolley equipped with an optical guidance sensor that detects the difference in the amount of light reflected from the floor surface and the guideline, the optical guidance sensor is attached to the running wheel so that the guideline is located at a position not in contact with the running wheels of the trolley. A self-propelled trolley, characterized in that the trolley is shifted to either the left or right in the direction of travel of the trolley with respect to the position of the trolley.
