Title: Hiroshi Sotokawa: Innovator in Printer Technology
Introduction
Hiroshi Sotokawa is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of printer technology, holding 2 patents that showcase his innovative approach to data transmission and processing.
Latest Patents
One of his latest patents involves a printer that detects data precisely in response to changes in data transmission speed. This printer, connected to a host computer, features a synchronizing signal output section that sends a synchronizing signal to the host computer. It also includes a data detection section that detects print data received from the host computer using a sampling signal. The print processing execution section performs print processing based on the detected print data, with the sampling signal having a frequency higher than that of the synchronizing signal. Upon detecting a change command for altering the clock rate of the synchronizing signal from the host computer, the printer instructs the host computer to stop transmitting data and change the synchronizing signal to the specified clock rate. After the clock rate change is complete, the printer signals the host computer to resume data transmission. A timer counts values sequentially, and upon expiration, a data output command signal is sent to a data transmission section, allowing data of a predetermined length to be transmitted from the data transmission section to the host computer.
