| PROBLEM TO BE SOLVED: To suppress the radiation of radiant noise generated between wiring patterns formed on the circuit pattern to outside the circuit board and a keyboard device by forming a ground pattern between wiring patterns. SOLUTION: This device consists of wiring patterns 31 led out of solder lands 8 and 9, output terminal parts formed at one-end sides of the wiring patterns 31, an integrated circuit for control which is connected to the solder lands 8 and 9, and the ground pattern 30 for holding an earth potential. Then the ground pattern is formed between the wiring patterns 31. Consequently, the wiring patterns 31 led out of the solder lands 8 and 9 have capacity connections with the ground pattern 30 arranged between the wiring patterns 31, and high frequency noise mixed with signals flowing through the wiring patterns 31 is made to flow to the ground pattern 30 by the capacitive connections. Consequently, the high-frequency noise mixed with the signals can be reduced. COPYRIGHT: (C)1997,JPO | ||||||

| PURPOSE: To dispense with a space for holding a key top switch and miniaturize a key input device by boring a hole in the upper surface of a receiving body for receiving a printed board, catching a key top into this hole to project its upper part from the hole, and energizing the key top in the projecting direction by an elastic member provided on the printed board. CONSTITUTION: A printed board 2 having a plurality of electronic parts 3 for input operation to a body not shown on the lower surface and a plurality of printed electrodes 6 on the upper surface is received in a receiving body 1. A hole 18 slightly larger than the diameter of a key top 4 to be inserted thereto is bored in one wall of the receiving body 1. At the beginning of assembling, the key top 4 having a wide engaging part 15 on the lower surface is inserted into the hole from the lower surface, and the upper surface of the key top 4 is projected while preventing the pass through of the key top 4 by the engaging part 15. Thereafter, the center part lower surface of a contact electrode 7 for the electrode 6 provided on the lower surface of the engaging part 16 is pushed up by a leaf spring 5 mounted on the board 2 to ordinarily bring the electrodes 6, 7 into cut state.

| In a keyswitch structure, a number of recesses are formed in a lower case, and a projection with a flat top surface is formed inside each of the recesses. The recesses communicate with each other by means of grooves formed on the lower case, and fixed contacts are provided on the projections. A pattern is formed on the under surface of a flexible substrate put on the lower case so that movable contacts, included in the pattern, face the fixed contacts. An elastic sheet with a number of buttons is put on the flexible substrate, and the flexible substrate and the elastic sheet are fixedly held between an upper case and the lower case. When any of the buttons of the elastic sheet is pushed, the elastic sheet and the flexible substrate are elastically deformed to bring the movable contacts into contact with the fixed contacts. | ||||||

| An improved flexible substrate for a touchpad (10), with the flexible substrate (10) having conductive ink for forming a sensor array (14). A printed circuit board (26) is also used, but only for the components (16, 18 and 20) which need to connect to the array, and not the array, thus giving a smaller printed circuit board. The printed circuit board (26) can have the components compactly mounted on it taking advantage of the close spacing available in PC board technology. The PC board itself has wider spacing on its contacts at its outer edges, allowing it to be attached by conductive glue to the flexible substrate. | ||||||

| A tactile switch assembly can include a tactile switch structure electrically connected to one end of a flexible circuit. The tactile switch assembly has a first length when the flexible circuit is in an unfolded state and a smaller second length when the flexible circuit is in a folded state. The flexible circuit folds over itself one or more times in the folded state. The tactile switch structure can include a stiffener positioned over a switch. The flexible circuit can extend over at least a portion of a top surface of the stiffener and wrap around the stiffener at a bend region and extend under at least a portion of a bottom surface of the stiffener. One or more component chambers can be created in openings in the stiffener that provide additional locations for one or more electrical components to be electrically connected to the flexible circuit. | ||||||
