Latest Patents

Yamamoto's latest patents showcase his ingenuity in developing advanced color image recording apparatuses. One of his notable inventions is an apparatus for forming a color image, which features an edge detection device equipped with image sensors that capture longitudinal edges of electrostatic recording paper. This device also includes a mark detection feature that identifies registration marks strategically placed along the edges of the recording medium. By detecting these edges during the initial pass and storing the data, the apparatus ensures precise alignment during subsequent passes, allowing for corrections of any expansion or shrinkage of the recording paper. Additionally, the system can discern oblique motion through timing differences between registration marks, which further enhances accuracy in color image positioning.

Another innovative development is his design of an automatic roll-in take-up reel, which simplifies the winding and unwinding of a continuous sheet-like recording medium. This invention incorporates multiple cams within a hollow cylindrical body to securely hold the recording medium while maintaining alignment, even under oblique conditions. This feature allows for efficient winding of the medium around the take-up roller, driven by a smart guiding unit that directs the recording medium appropriately.
