The invention relates to the technical field of optical micro-imaging, and provides a micro-film rewinding device and a micro-film exposure imaging method. The device comprises a film release shaft used for releasing a micro-film and a film take-up shaft for storing the micro-film. Multiple micro-films are arranged side by side on the film release shaft and the film take-up shaft. An image on a display screen is divided correspondingly to multiple parts side by side. The multi-part image on the display screen is correspondingly exposed onto multiple micro-films. Compared with the prior art, the device provided by the invention has the advantages that the film release shaft and the film take-up shaft can accommodate multiple micro-films, and synchronously wind the micro-films up; the positions of a lens and the display screen are adjusted accordingly, and then the multi-part image on the display screen is correspondingly exposed onto multiple micro-films; simultaneous exposure and imaging of multiple micro-films can be realized; and the work efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of optical microfilm imaging, and in particular relates to a microfilm winding device and a microfilm exposure imaging method. Background technique [0002] The technical application of recording digital images on microfilm is a safe way of off-line heterogeneous preservation of digital images; it is to expose electronic files to microfilm in the form of digital images, and visualize them after developing, fixing, washing and drying The image film can be stored for up to 500 years, which can ensure the safety of important data. At the same time, the image recorded on the film can also be restored to a digital image through the film image restoration imaging device; Safe and effective way. Both the equipment for outputting electronic information to the microfilm and the equipment for restoring the image on the microfilm to electronic information need to be equipped with a winding device that drives the micro...
