Claims

[Scope of utility model registration request]

A rail structure laid on an article transfer path along the ceiling, a ceiling self-propelled vehicle supported by this rail structure and running along the rail structure, and a ceiling self-propelled vehicle that controls the traveling of this ceiling self-propelled vehicle. The signal transmitting and receiving device includes a traveling vehicle and a signal transmitting and receiving device provided at each corresponding position of the rail structure, and the signal transmitting and receiving device includes:
It has at least a first sensor that sets a stop position of the ceiling self-propelled vehicle, and a second sensor that sets a destination of the ceiling self-propelled vehicle, and the first and second sensors are connected to a light emitter and a light receiver, respectively. Of these light projector and light receiver, one is mounted on the rail structure and the other is mounted on the ceiling self-propelled vehicle, and a light passage path between the light projector and the light receiver in the first sensor is provided. . An overhead traveling device for transporting articles, wherein a passage path between the light projector and the light receiver in the second sensor is set to be in a non-parallel state.
