Electronic copying apparatus with trimming function

An electronic copying apparatus comprising:

• an original table for placing thereon an original to be copied;
• original scanning means for optically scanning the original to be copied placed on said original table to obtain an optical image;
• image forming means for receiving the optical image obtained by said original scanning means and transferring an image corresponding to the optical image onto an image recording medium;
• erasure portion designation means, for designating position data corresponding to at least an arbitrary portion to be erased, which is not required to be copied, of the original placed on said original table;
• storage means for storing the position data of the portion to be erased designated by said erasure portion designation means, the position data being stored in units of originals for a plurality of originals;
• readout designation means for designating the position data, corresponding to the portion to be erased of said plurality of originals stored in said storage means, and
• image erasure means for receiving the position data of the portion to be erased read out from said storage means by said readout designation means and erasing a corresponding portion of the image to be formed by said image forming means.
