Latest Patents

One of Ohtani's latest inventions is a photographic processing apparatus. This device is designed to uniformly irradiate the surface of negative film without increasing the size of the mirror tunnel. It also reduces the overall size of the device and minimizes electric power consumption. The invention utilizes a fly eye lens as a diffuser plate, which consists of multiple micro-lenses arranged on a transparent substrate. This configuration helps to lead incident light into the mirror tunnel while reducing light loss. Additionally, the fly eye lens ensures that light is uniformly dispersed onto the photo film surface, even when the incident light is not strongly diffused. The optical path includes first and second fly eye lenses and condenser lenses that work together to create uniform light irradiation onto the negative film.

Another significant patent is a method and device for continuously feeding film. This innovation allows films to be fed to a photographic printing apparatus one after another without splicing them together. The continuous film feed device features a case, a rotatably mounted film core, and film presser arms equipped with presser rolls. This design enables the films to be wound around the film core with their ends overlapping, ensuring a smooth and efficient feeding process.
