Abstract
Abstract A photographic copying apparatus is provided with several document holders for individually carrying separate documents which are to be copied. Use of the copying apparatus involves having a first one of the document holders in a document copying position while a second one of the document holders is in a document loading and unloading position. Each document holder includes a wedge member on a forward portion thereof, which may be slipped beneath a rearward portion of another document holder so as to raise that holder. To interchange the respective positions of the first and second document holders, the second document holder is moved in a forward direction out of the document loading and unloading position, causing a wedge member thereof to slip beneath a rearward portion of the first document holder and to raise that holder out of the document copying position. In this way, the first document holder will be located on top of the second document holder as that holder is moved into the document copying position. Thereafter, the first document holder is moved in a rearward direction into the document loading and unloading position.
