<p>PURPOSE:To provide functions easily with a simple constitution by providing a device generating the coordinate value of a point indicated on a tablet plate with a means detecting the simultaneous indication of two points or more. CONSTITUTION:The device generating the coordinate value of a point indicated on the tablet is provided with the means detecting that two points or more are simultaneously indicated. For instance, two electrode parts of a tablet 31 are connected to driving circuits 32, 33 and detecting circuits 34, 35 respectively and the coordinates or function of a point indicated by a tablet control part 36 on the basis of a signal between detecting lines detected by the detecting circuits 34, 35 is transferred to a CPU 37. Subsequently, the CPU 37 prepares output information by using information from the tablet control part 36 and transfers the information to a display part 38 to display characters, patterns, etc. When two points are simultaneously depressed, the distance, direction, etc. of the depressed two points are divided into several functions and transferred to the CPU 37.</p> |
