A pen tablet capable of detecting a position of a stylus and supplying positional coordinates to an external computer is provided. The pen tablet includes a detector that generates hover coordinates as the positional coordinates in a hover state and generates contact coordinates as the positional coordinates in a contact state. The pen table includes a communicator that performs communication with a device driver and a given application executed by the external computer, a storage device, and a controller. The controller determines whether the communication with the device driver is requested of the communicator, operates in a tablet mode, for supplying the hover coordinates and the contact coordinates to the device driver, when the communication is requested, and operates in a paper mode, for discarding at least part of the hover coordinates and recording stroke data generated based on the contact coordinates in the storage device, when the communication is not requested.
