Latest Patents
One of Sawada's latest patents is a keyboard device designed to reduce the number of parts required for its construction. This invention features hammers that are rotatably linked to a chassis, with keys also rotatably linked to the hammers. Guiding pins extend in the widthwise direction of the keys and are inserted into a guiding groove on the chassis. This design allows for the downward displacement of the keys to be guided effectively, eliminating the need for additional links and thereby reducing the overall number of parts.
Another recent patent involves a keyboard device that aims to suppress any reduction in key operability. This design includes a rear guiding member with a pair of guiding surfaces that face forward and rearward, formed along an arc that is convex toward the front. The keys are equipped with sliding surfaces that interact with these guiding surfaces. This interaction regulates the key's displacement in the front-rear direction, ensuring that the operability and tactile feedback during key presses are maintained.
