Latest Patents

Oosake holds a patent for a film positioning mechanism for a microfilm camera. This mechanism includes a movable platen that mounts a rotary shaft member and brake means for selectively locking the shaft member against rotation. When the brake means is engaged, a film strip held to the platen by vacuum pressure is advanced along with the platen by a drive motor. Conversely, when the brake means is disengaged, the film driving roller is driven by the motor via the shaft member and a belt, allowing the film to advance while the platen remains stationary. This innovative design enables a single motor to both feed the film and move the platen, operating in both roll-to-roll and roll-to-sheet modes.
