Title: Hironobu Machida: Innovator in Image Forming Technology

Introduction

Hironobu Machida is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of image forming technology, holding a total of 18 patents. His innovative work has advanced the efficiency and performance of image forming apparatuses.

Latest Patents

Among his latest patents is an image forming apparatus and image forming method. In this invention, during the initializing process at the time of switch-on, a scanner CPU sends an initialization command request to a system CPU. Upon receiving this request, the system CPU sends an initialization command back to the scanner CPU. The scanner CPU then executes the initializing process and informs the system CPU upon completion. Once all sub-control units, including the printer CPU and panel CPU, confirm the completion of initialization, the system CPU instructs an LCD to display 'Ready' and enters a standby state. Another notable patent involves the detection of the direction of an original, which is performed not during scanning but while in standby for printing. This innovation helps prevent the deterioration of scanning performance.
