In a sliding door apparatus, a first detecting apparatus has: a light emitter that is disposed on a side portion of a doorway; and an imaging means that faces the light emitter from an opposite side of the doorway and captures images of the light emitter, detecting objects that are present in the doorway. A second detecting apparatus has: a light source that emits a light beam along a side portion of the doorway; and a photodetector that receives the light beam from the light source, detecting objects that are present in a vicinity of the side portion of the doorway. A controlling apparatus controls opening and closing of a door based on information from the first and second detecting apparatuses. |
