Latest Patents

Among his latest innovations, two patents stand out:

1. **Exposure Controlling Apparatus** - This invention pertains to a color copying machine designed to copy images on photosensitive materials. It features a movable scanning exposure element equipped with a light source that irradiates a document and projects the reflected light through a window. To achieve the desired spectral intensity, at most, two of the three primary color filters can be used. These filters adjust the light path, while the inclusion of a diaphragm regulates the light quantity without affecting the fixed spectral intensity.

2. **Charging Apparatus** - This patent describes a unique charging apparatus where the back plate, forming part of a shielding member around a discharging wire, includes an elongate opening. This design facilitates the maintenance of the cleaning member within the cleaning region of the wire while also allowing for separation via a cam groove. Notably, the distance between the discharging wire and the side plate is greater than that to the back plate, ensuring effective operation.
