Title: Keiichi Ikoma: Patents in Printing and Cash-Register Systems

Introduction

Keiichi Ikoma is an inventor associated with Nara, Japan. His patent work includes inventions addressing printer recovery after power interruptions and data-error detection in electronic cash-register systems. He is associated with Sharp Kabushiki Kaisha, also known as Sharp Corporation. His listed portfolio includes 4 patents.

Latest Patents

One of Ikoma’s listed patents describes a printer with an improved power-failure restart function. The printer detects when power is disconnected and restored, then checks whether any nonblank characters were printed on the line where printing stopped. If characters were printed, the printer marks through that line after power resumes. If only blanks were printed, it reprints the intended contents on the same line rather than advancing to a new one. This approach helps the printer continue interrupted work while accounting for what may already have been printed.

Another listed patent concerns data-transmission error detection in an electronic cash-register system. It describes transmitting and receiving cash registers connected in a loop. Data travels from the transmitting register to the receiving register while corresponding data is sent back in the opposite direction. The system compares the original data with the returned data to identify transmission errors.

Career Highlights

Ikoma’s listed inventions address practical reliability challenges in business equipment. His printer design focuses on recovering from power loss without unnecessarily duplicating or misplacing printed content. His cash-register system uses returned data and comparison to check the accuracy of serial transmissions.
