Latest Patents

Printer Having Replaceable Print Head. This invention concerns heat-sensitive label printers. It describes a printer body and print-head housing, with a thermal print head housed inside. A flicking needle base and locking base help secure the assembly, while a fixation component is located within the locking base. The design also includes a mounting box containing a reel and driving gear, with a reel roller and thrust gear arranged within the reel.

Structure for Automatically Measuring Paper Width for Printer. This invention uses a width-adjustment mechanism and at least one restraint arm to position paper. An inductor inside the printer detects contact with the moving mechanism or restraint arm and outputs a displacement signal. The arrangement allows users to adjust the restraint arm manually or through the width-adjustment mechanism so it can clamp the paper appropriately.

Career Highlights

Liu’s listed inventions address practical printer functions: making print heads replaceable and enabling paper-width adjustment through a displacement-sensing structure. Together, they reflect an emphasis on printer maintenance and paper handling.
