Introduction

Yoshinori Chida is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of printing technology, holding a total of 8 patents. His work has focused on enhancing the functionality and efficiency of printing devices.

Latest Patents

One of his latest inventions is the impact type dot printer. This printer features a print head that reciprocates back and forth in front of a rotationally driven platen, allowing it to print dot matrix characters on a recording medium. The print head includes a single print hammer actuated by an electromagnetic driver. A series of print timing signals are produced in synchronism with the platen's rotational speed, and a home signal is generated each time the print head leaves its home position during the printing of each line. A control circuit initiates the printing of each line in response to the first print timing signal produced after the home signal is generated, ensuring synchronization between the print hammer actuation and platen rotation.

Another significant invention by Chida is the cassette type ink ribbon device. This device comprises a pair of cassette cases that can be mounted in spaced-apart, non-touching relation on a printing apparatus. An endless ink ribbon extends through these cassette cases. A transfer roller and an ink roller are rotatably mounted within one of the cassette cases and are in contact with each other to replenish ink onto the ink ribbon. A slidable tensioner is located within the other cassette case to apply a tensioning force to the ink ribbon. This innovative design allows for minor variations in the spacing distance between the cassette cases when mounted on the printing apparatus, accommodating sliding movement of the guide body.
