摘要： PURPOSE:To detect the position coordinate of a support with high accuracy even when the capacity of the support is large by correcting a contact position coordinate corresponding to the impedance of the support and a calculated contact position coordinate when the impedance of the support exceeds a prescribed value. CONSTITUTION:When a finger 14 is touched on a touch panel 18, either stored impedance exceeds the prescribed value, and the presence of touch is decided, and the impedance observing from each terminal side of L1, R1, U1, and D1 is measured and stored. Next, the coordinate of an indication position is calculated by using the impedance stored before the touch and in touching, and the capacity CB of a human body is found from the impedance in touching measured previously and stored in a memory. When the capacity CB of the human body exceeds a comparatively large prescribed value, the coordinate value (X, Y) is corrected. In such a way, it is possible to detect a found coordinate value with high accuracy.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacture cost and to stabilize the operation. SOLUTION: A power wiring frame 70 is equipped with beltlike wires and when one-end parts of a Y driving circuit board 20B, a control circuit board 50B, and an X common driving circuit board 30B are clamped in common, some of the beltlike wires come into contact with pads on those circuit boards 20B, 30B, and 50B; and those pads are connected to the ground conduction surfaces in those circuit boards 20B, 30B, and 50B. The power wiring frame 70 is provided with substrate insertion slots and after the power wiring frame 70 is fixed to a PDP(plasma display panel) 10, those circuit boards 20B, 30B, and 50B may be inserted into the substrate insertion slots of the power wiring frame 70. Further, the ground conduction surfaces of adjacent circuit boards may be connected by a conduction plate instead of the power wiring frame 70.

摘要： PURPOSE:To detect contact position coordinates even with the quick touch by processing an impedance measurement and a position coordinate operation to use the impedance measured value during the previous contact in parallel. CONSTITUTION:A pair or above of terminals opposite to a resistance film is provided at a touch panel 18, the impedance viewed from one side terminal and the impedance viewed from other side terminal are measured by a microcomputer 44 and this is temporarily stored. The microcomputer 44 reads the impedance value measured before the contact of the instructed matter to the touch panel 18 and during the previous contact, from a memory at the idle time during the impedance measurement, operates the contact position coordinates and outputs the arithmetic result. Thus, since the impedance measurement and the output of the position coordinate operation and the arithmetic result of the previous contact are processed in parallel, the position coordinates of the quick touch can be also detected.

摘要： PURPOSE:To eliminate the danger of disconnections by adding a switching circuit for the detection of coordinates to an area where coordinate input panels are superposed on a leading part at the periphery of an escutcheon. CONSTITUTION:A coordinate input panel 11 is superposed on the surface of a CRT 8 and also on a leading part 10 at the periphery of an escutcheon 7 to form a box. Then a switching circuit 9 is formed in the area of the leading part 10 of said box. In such a way, a stable fixing way is facilitated and no danger of disconnections is produced owing to no use of lead wires.

摘要： PURPOSE:To reduce the load on a host computer by storing key correspondence part coordinate values and blind area coordinate value and transmitting only data values obtained by detecting and computing touched coordinates to a host computer. CONSTITUTION:The arithmetic controller 23 of a coordinate input device is connected to a storage device 25. This storage part is stored with key correspon dence part coordinate values 25-1 and blind area coordinate values 25-2 provided by sectioning a touch panel surface. The arithmetic controller 23 detects the position touched on a touch panel device 11 and compares it with the coordinate values stored in the storage device 25 immediately. Consequently, it is know how the position stands in the key size area or whether it is in the blind area, so a corresponding data value is found by the arithmetic controller 23. This data value is transmitted to the host computer.

摘要： PURPOSE:To evaluate the change of an impedance measurement condition by providing a two-dimensional touch panel where terminals are provided along one pair of first and second sides facing each other and the other pair of third and fourth sides facing each other and repeatedly measuring impedances viewed from terminals of first, second, third, fourth, second, first, fourth, and third sides in this order. CONSTITUTION:A touch panel 1 is provided with terminals along one pair of first and second sides facing each other and the other pair of third and fourth sides facing each other, and impedances CL1, CR1, CU1, CD1, CR2, CL2, CD2 and CU2 viewed from terminals of first, second, third, fourth, second, first, fourth, and third sides are repeatedly measured in this order by an impedance measuring means 2. A measurement abnormality discriminating means 3 discriminates measurement abnormality if an absolute value Z of the difference between the sum of measured impedances viewed from terminals of first and second sides and that viewed from terminals of third and fourth sides is larger than a set value. Thus, the change of the impedance measurement condition is evaluated.
