Medium handling apparatus and medium handling method

A medium handling method of a medium handling apparatus, the method comprising:

• during a media counting and rejection process, receiving media from a user into internal space of a deposit/withdrawal unit;
• during the media counting and rejection process, determining normal media and reject medium of the received media by a discrimination unit;
• during the media counting and rejection process, receiving the normal media via a separator/accumulator of a temporary storage unit, the separator/accumulator located below a first fixed plate and located closer to the deposit/withdrawal unit than a rear side of the medium handling apparatus to enable extension of the temporary storage unit to the rear side of the medium handling apparatus;
• during the media counting and rejection process, storing the received normal media between the first fixed plate and a second plate of the temporary storage unit by moving the second plate of the temporary storage unit backward or forward after determination by the discrimination unit, the second plate located further away from the separator/accumulator than the first fixed plate;
• during the media counting and rejection process, returning the reject medium to the deposit/withdrawal unit without storing in the temporary storage unit;
• during a deposit receipt process subsequent to the media counting and rejection process, sending the normal media in the temporary storage unit to recycling cassettes according to types of the normal media;
• receiving a signal for tallying numbers of media stored in each of the recycling cassettes to initiate an internal tallying process;
• during the internal tallying process, separating stored media in the recycling cassette and conveying the separated media from the recycling cassettes to the discrimination unit;
• during the internal tallying process, discriminating the separated media from the recycling cassettes through the discrimination unit, and storing the numbers of the separated media in a controller;
• during the internal tallying process, storing, in the temporary storage unit by moving the second plate of the temporary storage unit backward or forward to accommodate the media between the first fixed plate and the second plate, the media from the recycling cassettes passed through the discrimination unit;
• after storing the media in the temporary storage unit in the internal tallying, sensing the number of media stored in the temporary storage unit by separating and passing the media of the temporary storage unit through the discrimination unit to one or more of the recycling cassettes for storage;
• displaying the numbers of separated media as sensed in the internal tallying;
• receiving first additional media in the temporary storage unit by moving the second plate backward or forward to accommodate the first additional media between the first fixed plate and the second plate;
• and
• sending normal media of the first additional media from the temporary storage unit to the recycling cassettes for refilling the recycling cassettes.
