Title: The Innovations of Tadashi Yamamoto
Introduction
Tadashi Yamamoto is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of document reading technology. With a total of 3 patents, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a method for controlling the sub-scanning of document reading apparatus. In this method, the speed, acceleration, or deceleration of the reading section is controlled according to the amount of information stored in a buffer memory. This buffer temporarily stores information read by the reading section. The values of the movement speeds, accelerations, and decelerations are predetermined based on the stored information amount. During the control of the reading section, one of these values is selected according to the currently stored information amount. This innovation helps prevent any vibration in the reading section, thereby eliminating irregularities in the sub-scanning process.
Another significant patent is for a picture data reading device. This device employs a plurality of image sensors for reading separated colors and includes a delay device in the processing circuitry of at least one of the image sensors. The delay device can be set to delay the signal output from the associated image sensor to an arithmetic circuit for a variable time corresponding to a multiple of the line scanning period. This allows the image sensors to be less accurately positioned while still ensuring that picture data signals for the same line can be fed to the arithmetic circuit simultaneously.
