Title: Yasuo Nakamura: Innovator in Image Forming Technology
Introduction
Yasuo Nakamura is a prominent inventor based in Toyokawa, Japan. He has made significant contributions to the field of image forming technology, holding a total of 12 patents. His innovative designs have advanced the efficiency and functionality of image forming apparatuses.
Latest Patents
One of Yasuo Nakamura's latest patents is an image forming apparatus that feeds a recording sheet from a sheet feed roller. This apparatus clamps the recording sheet between an image carrier and a transfer roller, transferring a toner image to the recording sheet while conveying it. It also fixes the transferred toner image on the recording sheet. The design includes a mechanism that vertically swings an elevating plate, which stacks the recording sheets. Additionally, a rotation drive mechanism synchronizes the rotation of the sheet feed roller with the elevating plate swinging mechanism. A recording sheet detector is employed to detect the leading edge of each recording sheet fed from the sheet feed roller. The conveyance controller measures the sheet feed time from the start of the sheet feed operation to the detection of the leading edge, setting the sheet feed start timing for the next recording sheet based on this measurement.
Another notable patent is for an image forming apparatus that can stably detect the temperature of a fixing device, regardless of its orientation. This apparatus can be positioned in either a first or second position, with the second position differing in inclination from the first. It includes a fixing unit with a fixing roller and a pressurizing roller, which forms a fixing nip to thermally fix a toner image on a recording sheet. The design features a temperature sensor that detects the surface temperature of the fixing roller without contact. A heater is included to heat the fixing roller, and a controller manages the heater based on the detected surface temperature.
