Image conversion apparatus having scanning mechanism and optical system on single base

摘要

An image conversion apparatus for converting an image recorded on an original into an electrical signal upon reception of illumination light transmitted through the original, includes a moving device for mechanically moving the original while holding the original, an optical device for focusing the illumination light transmitted through the original on a focal plane as an image, and an image sensor device for converting the image focused on the focal plane into an electrical signal. The moving device and the optical device share a single base, and a shielding device for preventing a lubricant from being scattered from the moving device to the optical device is formed between the moving device and the optical device.
