Latest Patents

Among his latest inventions is an image reading apparatus, along with its shading correction method and the corresponding program for implementation. This novel image reading apparatus integrates a shading correction mechanism that minimizes the number of component parts when compared to conventional designs. By increasing the design’s degree of freedom, Tsutaoka's invention enables a notable reduction in both size and weight. The device features a contact glass that guides the original document to the image reading position, while a glass holding member securely maintains the glass in place. A line image sensor reads the image of the original document conveyed to this position through the contact glass. Importantly, a reference member is placed at a different location on the contact glass. The system includes a moving mechanism that allows relative movement between the line image sensor and the reference member, facilitating the alternating reading of the original and reference. A drive section externally directs the moving mechanism to adjust the positioning of both the line image sensor and the reference member as needed.
