Abstract
According to a data input system with a pointing device, a keyboard device is provided with a pointing device interface and a key code generator. The keyboard device incorporates a microprocessor for generating a key code corresponding to a depressed key. The key code generator assigns data input through the pointing device interface to a nondefined key code. The data from the pointing device having been assigned a nondefined key code, is supplied as a key code from the keyboard device to a keyboard interface in a data processing device. The data processing device checks a specific bit of the data supplied thereto and determines that the received data is data originally supplied from the pointing device.
