Abstract: A coordinate input device includes a flat substrate portion, a plurality of strain gauges formed on one surface of the substrate portion, an operating portion disposed at about the center of the other surface of the substrate portion, and a printed board on which one surface of the substrate portion is mounted. Since a portion of the printed board opposing the strain gauges has a through hole, it is thereby opened. Therefore, even when the substrate portion is bent by tilting the operating portion, the strain gauges will not touch the printed board. Accordingly, it is possible to omit flux cleaning, to shorten the assembly time, and to reduce the cost.

Abstract: A coordinate input device includes a columnar operation member and a printed circuit board to which the operation member is mounted on a major surface thereof. The printed circuit board includes a deformation part which can be deformed when the operation member is tilted or depressed. Deformation detecting elements disposed on one major surface or the other major surface of the deformation part determine the amount of deformation of the deformation part. A substrate such as used in a known coordinate input device is eliminated from the operation member so that the number of components is reduced and the coordinate input device is easily manufactured.

Abstract: A keyboard is constructed so that a ratio of a dimension between a first latching portion of a first lever and a pivotally supporting portion thereof to a dimension between this pivotally supporting portion thereof and a second latching portion thereof is equal to a ratio of a dimension between a first latching portion of a second lever and another pivotally supporting portion thereof to a dimension between this pivotally supporting portion thereof and a second latching portion thereof. Thus, when the key top descends, the second latching portions of the first and second levers are placed outside the first latching portions of the first and second levers. Consequently, reduction in thickness of a keyboard is achieved.

Abstract: There is provided a spin coating process of forming a coating film through spin coating of a solution on a substrate, wherein periphery portions of the coating film are removed. The film forming method comprises the steps of: (a) initiating dropwise dispensing of a first solvent having a relatively low affinity for the coating film at a position slightly insider a periphery of the substrate covered by the coating film; (b) initiating dropwise dispensing of a second solvent having a relatively high affinity for the coating film at a position closer to the periphery of the substrate as compared to the position of the dropwise dispensing of the first solvent, where the dropwise dispensing of the second solvent is initiated simultaneous to or after the initiation of the dropwise dispensing of the first solvent; (c) stopping the dropwise dispensing of the first solvent; and (d) stopping the dropwise dispensing of the second solvent after stopping the dropwise dispensing of the first solvent.

Abstract: A game machine operation device wherein a first grip section and a second grip section have their outer sides curved into the shape of an arc, with the curved surfaces serving as guide sections along which the operator can move his palms. Therefore, the operator is capable of placing his hands or fingers used for operating the device in a comfortable position on the first and second grip sections and freely move his hands or fingers along the curved surfaces. In conventional game machine operation devices, the grip sections are formed so as to extend vertically downward, which prevents the operator from changing the position of his hands, depending on his hand size, so that an operator with large hands cannot operate the operation device easily, causing him to get tired hands or fingers.

The input apparatus includes a tablet having a plurality of X electrodes and Y electrodes arranged in the form of a matrix on the respective top and bottom surfaces of a glass substrate. The input apparatus also has a first oscillation circuit connected to the X electrodes through an analog switch. It is further provided with an input pen containing a second oscillation circuit. When the pen is used to perform the input operation through use of coordinates, the following method of determining the coordinates designated by the pen is employed. A voltage oscillating from the pen is applied to each electrode through capacitance, and the resulting output voltage varies depending on the distance from each electrode to the pen. Based on the varied output voltages, a predetermined computation process is executed to determine the coordinates designated by the pen.
