摘要： A coordinate input apparatus includes a sensor (i.e., a detection unit) for detecting an operation status on an operation surface by a coordinate indicator, and a front light (i.e., a lighting unit) disposed on the sensor, for illuminating the operation surface. In the case where the operation surface of the coordinate input apparatus is illuminated, light emitted from a LED is propagated within the light guide plate and then output from the prism surface. The light is reflected from the reflection plate, and directs toward the operation surface with its direction being changed. Accordingly, the operation surface can be illuminated.
