PROBLEM TO BE SOLVED: To make it possible to use a tablet and a display device at a distance from a processor by constituting a transmission device which sends a signal inputted to the tablet by radio and a battery which drives the transmission device in one body and arranging a reception device which receives the signal from the transmission device on the processor. SOLUTION: The transmission device 8 is provided which sends information on a figure image and characters inputted on the tablet 1 in the form of an infrared-ray signal and the processor 3 is provided with the reception device 9 which receives the infrared-ray signal. The signal received from the transmission device 8 is received by the reception device 9 and restored by the processor 3 to information on the figure image and characters, and the information restored by the processor 3 is displayed on a display device 2 as the original figure image and characters. Consequently, a cable connecting the table 1 and processor 3 or display device 2 is not used and the tablet 1 can be placed at a distance from the display device 2 for input to make the device small-sized and also improve the handling. |
