Abstract

PURPOSE:To reduce an interface terminal and to improve the operability of an input by selecting coordinate data on a tablet to which a coordinate input is designated, adding identifying data to the coordinate data to identify the tablets of more than two number, converting them to serial data are outputting them. CONSTITUTION:Control parts 5 and 6, which are composed of a coordinate converting part 7 to convert position information on the tablet given from a pen and a signal generating part to generate a control signal INF to identify the tablet to designate the coordinate input by the pen or an identification circuit part 8, are provided in each tablet. An interface part 9 selects the coordinate data from the control parts 5 and 6 by the control signal INF and the identifying data are added to the coordinate data to identify two tablets 1 and 2, converted to the serial data and outputted. Thus, the plural coordinate designating tablets of a low cost, a high resolution and a high accuracy can be utilized in a comparatively small area and the input of a number of different coordinate values goes to be possible.
