Title: Akira Igarashi: Innovator of Thermal Printing Technologies

Introduction

Akira Igarashi, based in Katsuta, Japan, is a notable inventor with two registered patents focusing on advancements in thermal printing technology. His work reflects a commitment to improving the efficiency and functionality of printers, showcasing his inventive spirit.

Latest Patents

One of Igarashi’s recent patents is a multicolor thermal printer recording medium transmission mechanism. This innovative design involves a sheet of recording paper positioned between two drums located on opposite sides of a platen roll, which faces a line-type thermal head. An endless belt, mounted on the outer peripheries of the drums, assists in the paper movement during various printer operations. The implementation of one-way clutches allows the paper to rotate with the drums during the recording process while being driven by the endless belt for feeding and delivery. This intricate mechanism ensures that the sheet of paper is efficiently fed and removed, allowing for seamless printing operations regardless of the sheet length.

His second patent is a paper tension adjusting device and method for printers. This device features tractors equipped with feeding pins capable of changing feeding apertures in the paper, with the ability to adjust paper tension widthwise. By detecting the paper thickness based on hammer flight time, the desired tension can be set accurately. Additionally, the device enables lengthwise tension adjustments through paper clampers, enhancing the precision with which paper is handled during printing.
