Latest Patents

One of Kaizaki's latest patents is a multidirectional input device that features a ring-shaped resistance element layer. This device includes first and second conductive layers shaped in arcs that correspond to the resistance element layer, along with a knob that has a ring-shaped protruded section. The resistance element layer is designed with at least a pair of electrodes and is formed on a flexible insulating substrate. When the knob is tilted, it brings the resistance element layer into contact with either the first or second conductive layer. This mechanism allows for the generation of a high-resolution output signal concerning the tilt angle, which is then processed by a microprocessor to detect and recognize the angle or direction.

Another notable patent is an electronic apparatus that facilitates the replacement of an input device. This apparatus is equipped with an input device that allows various input operations. The input device, which includes first signal generators, is positioned by being placed in an opening of a housing from the outside. A detachable cover secures the input device in place, while second signal generators inside the housing work in conjunction with the first signal generators. This design simplifies the replacement process, eliminating the need to open the housing or remove a wiring board during the replacement of the input device.
