Latest Patents
Among his latest inventions is the microfilm reader-printer. This device features a reader mode that projects images from microfilm onto a screen, as well as a printer mode that prints these images onto copy paper. The screen includes indexes that indicate various sizes of copy paper. For larger sizes, the index shows a smaller size than the actual paper size. The device utilizes a variable magnification lens, ensuring that the projection magnification for the reader mode is smaller than that for the printer mode when a larger copy paper is selected. Conversely, when a smaller or equal size paper is chosen, the magnifications for both modes are equalized.
Another significant invention by Otsuki is a microfilm camera designed to photograph multiple originals onto a microfilm. This improved camera is equipped with a display lamp that indicates when an original remains unphotographed, along with a buzzer that sounds an alarm in such cases. This feature prevents originals from being left in a non-photographed state for extended periods.
