US 5,854,670 A · Image forming device for both unbound and bound originals

Abstract

An image forming device having multiple direction lens system, a presetting system, a page turner, a movable platform to manipulate both unbound and bound originals, an image monitoring unit, a microcomputer-based control system and an image formation unit, is disclosed that provides the capability of automatic and manual image formation from both unbound and bound originals. The automatic image formation from bound originals is enabled in both Flat Open Mode (original 180.degree. face-up opened) and Angled Open Mode (originals less than 180.degree. face-up opened). Unbound documents can also be face-up loaded on the movable platform for the automatic image formation and will never be jammed. While having bound or unbound originals face-up positioned on the 3D-movable frame, the manual image formation in both single and dual projecting direction also becomes much easier and effective with higher copy quality. The page turner is capable of operating with lifting power to turn pages of bound or unbound originals in the automatic and continuous image forming process. The presetting system is able to set up an image field in a desired size for the image formation, eliminate dark edge shadows and tailor off unwanted portion of originals. The image monitoring means is provided to monitor the set-up of originals that enables visible adjustment of orientation, field and size of the originals before starting the image recording process.

Dependent claims

An image forming device for both automatic and manual image formation from both unbound and bound originals thereof, comprising:

image forming means for forming images of the said originals;
image recording means for recording the formed images of the said originals onto recording media;
means, having open and closed positions, for shutting off the image light to an image bearing member in the said image recording means;
means for presetting an image field in a desired size, eliminating any dark edge effect in the formed images of the said originals, preventing dark edge shadows from forming on the recording media with transferred images and avoiding a wasteful consumption of toner and a pollution in the said recording means;
means for monitoring the set-up of the said originals in different sizes so that the orientation, field and size of the images of the said originals can be visibly adjusted before starting an image recording process;
means for loading, positioning and manipulating the said originals;
means for turning pages of the said originals;
and
controlling means, having a microcomputer-based controlling unit, for programming and instructing the said device to perform the said image formation.
