Title: Takashi Tomizawa: Innovator in Image Recording Technology

Introduction

Takashi Tomizawa is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of image recording technology, holding a total of 15 patents. His innovative designs have enhanced the functionality and efficiency of image recording apparatuses.

Latest Patents

One of Tomizawa's latest patents is an image recording apparatus equipped with a detecting device. This apparatus forms images using a photo-sensitive sheet housed in a cartridge, which has a bar code attached to one side. The device calculates the remaining amount of the sheet by subtracting the used amount detected by a rotary encoder from the total amount read through the bar code. It displays this information on a screen, allowing users to know when to replace the cartridge. Additionally, the apparatus corrects the remaining amount based on the rewound sheet when a single copy mode is selected. This innovation ensures precise recognition of the remaining sheet amount at any time.

Another notable patent is an image recording apparatus that includes an exposure unit, a pressure developing unit, and a thermal fixing unit. This device utilizes separate image recording mediums, such as a microcapsule sheet and a developer sheet. The thermal fixing unit applies heat to the developer sheet, which carries the output image, without direct contact with the imaging surface. This design enhances the quality and efficiency of the image recording process.
