Display apparatus

A display apparatus for displaying images formed on an image bearing member, comprising:

• a plurality of movable image bearing members;
• image forming means for forming erasable images on said image bearing members;
• display means for simultaneously displaying the images formed on said image bearing members at an observation position;
• erasing means for erasing the images formed on said image bearing members;
• drive means for independently moving each of said image bearing members through said image forming means, said display means and said erasing means;
• and
• drive control means for selectively moving one of said plurality of movable image bearing members through said erasing means, wherein a selected image formed on said one of said plurality of movable image bearing members, and simultaneously displayed at the observation position, is erased.

A display apparatus for displaying images formed on an image bearing member, comprising:

• a plurality of image bearing members;
• reader means for reading an image on an original and for converting the read information into an electric image signal;
• memory means for storing a plurality of said electric image signals corresponding to a plurality of originals read by said reader means;
• image forming means responsive to said image signals stored in said memory means for forming a plurality of erasable images on the image bearing members;
• display means for simultaneously displaying said plurality of images formed on the image bearing members at a display position;
• a plurality of erasing means each corresponding to a respective image bearing member for erasing an image formed on the respective image bearing member;
• drive means for independently moving each of said image bearing members through said image forming means, said display means and said erasing means;
• designating means for designating one of said plurality of images formed on the image bearing members and simultaneously displayed at said display position;
• erasure control means, responsive to said designating means, for selectively erasing the image designated by said designating means, and for preventing erasure of a non-designated image simultaneously displayed on said image bearing members;
• and
• image formation control means, responsive to said designating means, for controlling said memory means, such that said memory means supplies a substitution image to said image forming means thereby forming said substitution image on one of the image bearing members and displaying said substitution image at said display position.

A display apparatus for displaying images formed on a movable image bearing member, comprising:

• a plurality of image bearing members;
• drive means for independently moving each of said image bearing members between a display position and a non-display position;
• image forming means for sectioning each of the image bearing members into a plurality of areas and forming an erasable image on each sectioned area, said image forming means being disposed at the non-display position and selectively forming the images on the plurality of sectioned areas;
• display means for displaying the images formed on the image bearing members at a display position, said display means having a display window allowing the images formed on the sectioned areas on the image bearing members to be simultaneously observed therethrough;
• a plurality of erasing means each corresponding to a respective image bearing member, disposed at the non-display position, for erasing the images formed on the respective image bearing member;
• and
• erasure control means for controlling said drive means and said erasing means, such that an image formed on a selected one of said plurality of sectioned areas of the image bearing member displayed in the display window is erased, and such that erasure of images formed on sectioned areas other than the selected one is prevented.
