Latest Patents

One of Yanagisawa's latest patents is a printer that avoids exposure of a star wheel. This innovative design features a simple configuration that prevents the media from lifting up when the media conveyance path opens. The platen top unit, which supports the first and second star wheels, is designed to be movable vertically and is separated from the opening and closing platen unit. This mechanism ensures that when the platen unit is moved to the open position to address issues like paper jams, the head elevator raises the platen top unit, retracting the star wheels to a position that minimizes contact with the user's hands.

Another significant patent is an invoice amount calculation method, device, and printer invoicing system. This system includes a manufacturer server that determines a first invoice amount or calculates a second invoice amount for an inkjet printer. It features a billing status acquisition unit that collects billing status information, including the actual print volume. The actual print volume calculation unit assesses whether the print volume is less than or equal to a specific volume, determining a fixed invoice amount or calculating a variable amount based on usage.
