Claims

[Scope of utility model registration request]

In a traveling body equipped with a photoelectric switch having a light emitting part and a light receiving part, the light receiving part is configured so that the light receiving part does not receive light from the light emitting part reflected from a light modulation means fixed to an unnecessary object to be detected. The safety device for a traveling object is characterized in that the light receiving section is configured to receive light from the light emitting section reflected from an object to be detected.
