Title: Tetsuji Shimojo: Innovator in Printing Mechanisms
Introduction
Tetsuji Shimojo is a notable inventor based in Waraishi, Japan. He has made significant contributions to the field of printing technology, holding a total of 2 patents. His work focuses on improving printing mechanisms, showcasing his innovative spirit and technical expertise.
Latest Patents
Shimojo's latest patents include advancements in printing mechanisms and printing head assemblies. The first patent details an improvement upon a cancellation type printing mechanism or a stored energy type printing mechanism that utilizes magnetic members, known as armatures. These armatures are attracted by a permanent magnet while resiliently deflecting resilient members connected to one end. The design incorporates electro-magnets that can be selectively energized to release the magnetic members, allowing them to be actuated by the energy stored in the resilient members, thus driving the printing elements. This construction prevents the magnetic member from striking against the corner of the electro-magnet's core, enhancing the mechanism's reliability.
The second patent describes a printing head assembly that features a permanent magnet to attract magnetic members, such as armatures, to store strain energy in resilient members like leaf springs. The assembly includes electro-magnets that cancel the magnetic flux generated by the permanent magnets to drive the magnetic members. The design aims to equalize the attracting force among multiple armature actuating mechanisms and adjust the height of the second yoke surface, ensuring optimal performance.
