Abstract: PURPOSE: To enable all the input means to control a single cursor by connecting the plural input means to a computer system with a single input port. CONSTITUTION: A selective controller 50 connected with at least two cursor controllers 10 is included so that each cursor controller may transmit a control signal to the selective controller and the selective controller may send a cursor moving signal corresponding to the control signal from the cursor controllers to the computer system. When a presently selected cursor controller is in an active state through a delay period longer than a periodical period between the transmission of the control signal, the selective controller 50 release the selection of the cursor controller to transmit the cursor movement signal to the computer system from another cursor controller coming into an active state to be selected.

Abstract: PROBLEM TO BE SOLVED: To provide a sure method and a device for detecting 'selection depressing' in a graphic input device for integrating a position input function and a selection input function. SOLUTION: When selection or selection cancellation by a user is identified, a threshold value identification filter circuit 20 compares the amplitude of the output of the graphic input device and the change rate of the amplitude with threshold value reference signals and corrects the output of the graphic input device based on the previously stored samples. Such a graphic input device is provided with an equal angle joy stick provided with a distortion gauge and a fixed resistor in a hierarchical voltage divider or the like. The output of the graphic input device is directly provided to the CPU 25 of a data processor during a masking period and the graphical operation of dragging or the like is executed while masking the unintentional change of a specified display position during the selection and the selection cancellation.

Abstract: PURPOSE: To improve a pressure sensor used for a keyboard by bending a base part having distortion sensing patterns so that it rises from the plane of a base, adhering it by making it lean on respective faces of the members so that it detects force given to the members and arranging it in a right-angle direction. CONSTITUTION: The patterns 102-108 which are formed by the distortion sensing transmission materials and which wind are formed on a plastic sheet 110 which is flexible to winding. Both ends of the distortion sensing patterns 102-108 are connected to lead terminal lines 112-126. Thus, the effect of circuit resistance depending on the patterns 102-108 is enlarged and the sensitivity of the distortion of the patterns is increased. One set constituted of the patterns 102 and 106 is orthogonal with the other set of the patterns 104 and 108. The rectangular part of a sheet 112 is divided by an X-form pattern and consequently the respective patterns 102-108 form different triangular pieces. The patterns 102-108 are triangles and they use a space at maximum as pieces.
