Latest Patents

One of Tsutomu Iesaka's latest inventions is an **Optical Displacement Measuring Device**. This advanced apparatus increases the valid light receiving area that is struck by light, thereby generating a larger signal. It effectively reduces the effects of unevenness or spottiness in the illuminance of the light source as well as dirt or scratches on the glass scale. The design includes multiple arrays of light-receiving elements that are strategically shifted in relation to the direction of movement of the glass scale. This innovative configuration ensures that the valid light receiving portions surpass the invalid light receiving areas, significantly enhancing measurement accuracy.

Another noteworthy invention is the **Stacker**, designed for efficient handling of printed sheets. This device features a housing with both inlet and outlet ports, and a tray positioned below the outlet port, capable of moving upward and downward. The stacker's transfer mechanism is ingeniously controlled in three stages: an intake speed for taking printed sheets in, a carrying speed for transporting the sheets, and a discharge speed for releasing them onto the tray. This design effectively prevents issues related to loading failures during automatic operations, particularly when dealing with concavely curled papers.
