Latest Patents

Among Yonemoto's notable inventions are two groundbreaking patents. The first is an **automatic focusing device for camera**, designed for automatic focusing cameras of the double image coincidence focusing type. This device employs a coupling mechanism that enables a focus detecting movable mirror to perform a scanning motion corresponding to the stroke of the shutter release operation. This allows for dynamic focus detection while indicating and memorizing the distance from the focal plane to the photographing objective. The device innovatively enhances the photography experience during shutter operation by interlocking focus detection and lens adjustments with the shutter mechanism itself.

The second significant invention is an **electromagnetic shutter controlling device for camera**. This innovative device releases the shutter to start exposure when energized and completes exposure when de-energized. It features a complex system including a shutter blade, driving springs, an electrical delay circuit, and an electromagnetic device that ensures precision in controlling exposure times. This advancement not only improves the speed of the shutter operation but also enhances the reliability of camera exposure mechanisms, making it a key development in modern photography.
