Latest Patents

One of Sakurai's latest patents involves a printer designed for printing continuous sheets with position detection marks. This printer features a mark detection function and a feed amount detection function that are typically enabled. Additionally, it includes a mechanism that operates in two modes: a sheet feed mode utilizing the mark detection function and another mode that relies on the set feed amount detection function. In the event of an error with the mark detection function, the printer seamlessly switches to the feed amount detection mode, allowing the printing operation to continue without interruption.

Another significant patent pertains to a ribbon feeder and printer system. This invention includes ribbon tension detecting means, which consist of plate-like lever bodies positioned on both the upstream and downstream sides of a platen. These lever bodies are equipped with rollers that respond to the tension of the traveling ribbon. If the swing of the lever body falls within a predetermined range, it activates either a ribbon feed motor or a ribbon take-up motor. Furthermore, the system incorporates a smoothing member that touches the ink ribbon to eliminate any wrinkles, ensuring a smooth printing process.
