Abstract
In a sliding door apparatus, a first entrance is opened and closed by a first door, and a second entrance that faces the first entrance is opened and closed by a second door. Imaging means that captures images across a space between the first entrance and the second entrance is disposed beside the space. An image processing and determining portion determines presence or absence of an obstruction inside the space based on image data from the imaging means.
