ABSTRACT:
A copying machine has a platen glass on which a document to be copied is set. An automatic document feeder (half ADF) and a platen cover (half platen cover) are positioned over opposite halves of the platen glass. The half ADF and the half platen cover can be connected to each other by a lock member so that the half ADF and the half platen cover open and close together against the platen glass. For copying a letter-size document, the half ADF is mainly used to automatically feed the document. For copying a ledger size document, the half ADF and the half platen cover are connected to each other and the document is set on the platen glass manually.
