Abstract:
A manually input data display system, comprising:a plurality of coordinate data input devices and at least one display device, each of the coordinate data input devices including: a coordinate data acquisition unit that obtains images manually input from the coordinate data input devices as coordinate data; a coordinate controller that controls processing of the coordinate data obtained by the coordinate data acquisition unit; and a transmitter that transmits the coordinate data; and the display device including: a receiver that receives the coordinate data transmitted from the plurality of the coordinate data input devices; a display controller that controls processing of the coordinate data received through the receiver; and a display unit that displays the manually input images based on the coordinate data; wherein the display controller of the display device divides a display area of the display unit into a plurality of individual display areas corresponding to the plurality of coordinate data input devices, and a selective display area that selectively displays the images displayed in the individual display areas; and wherein each of the coordinate data input devices further comprises: a temporary storage device that temporarily stores the coordinate data obtained by the coordinate acquisition unit; and an erasing unit that performs an erasing operation to erase the coordinate data stored in the temporary storage device; wherein the coordinate controller of each of the coordinate input devices transmits the coordinate data stored in the temporary storage device to the display device, through the transmitter, when the images manually input from the coordinate data input devices are entirely erased by the erasing unit.
