Abstract
The image sensorof the information processing apparatuscan capture the retroreflective sheetsubjected to infrared light emitted from the infrared emitting diodessince the retroreflective sheetis exposed when the open-close portionis opened. Therefore, it is possible to detect the input device. On the other hand, when the open-close portionis closed, the image sensorcan not capture the retroreflective sheetsince the reflective sheetis not exposed. Therefore, the input device is not detected.
