1. A substrate damage detection device configured to be mounted to a substrate transfer robot provided with a slidably-movable substrate support, the substrate damage detection device comprising: an image obtainer for obtaining an image of a periphery of a substrate placed on the substrate support; and a damage detector for detecting damage to the substrate by using the image obtained by the image obtainer, wherein the image obtainer includes an image capturing unit and an image capture controller, the image capturing unit being movable relative to the substrate along the periphery of the substrate, the image capture controller being configured to control movement and image capturing operation of the image capturing unit, and the image capturing unit comprises a camera including a line sensor, the camera being switchable in orientation so as to cause the line sensor to be selectively parallel to one of a first direction and a second direction defined with respect to the substrate support.
