Latest Patents

One of Handa's latest patents is a method and apparatus for processing photosensitive material. This invention provides an apparatus designed to process silver salt photosensitive material using a minimal amount of processing solution. The processing solution is engineered to uniformly react with the photosensitive material, ensuring high processing quality. The apparatus features a relatively small process tank and a developer supply roller that is partially soaked in the processing solution. This innovative design allows for the temporary storage of new or unused developer, which is then supplied to the photosensitive material in a controlled manner. As a result, the photosensitive material is processed evenly and efficiently, while also reducing the volume of processing solution needed, thus minimizing sludge accumulation and maintenance efforts.

Another significant patent involves a camera and photosensitive material feed unit. This invention allows for the input of a reproduction magnification, which adjusts the projection optical system accordingly. The system projects image light reflected from an original onto a photosensitive material sheet while synchronously feeding both the original and the photosensitive material. This advancement enhances the precision and quality of image reproduction.
