• a platen interposed between said upper cover and said front cover;
• means to selectively mount one or more of a group of components including a sound absorber, a printing sheet guide, a noise silencing cover and a page feeder;
• a pair of brackets each removably inserted in one of two engaging holes formed on opposite sides of said upper cover, each of said brackets having a first engaging portion located on an inner side of said bracket and a second engaging portion located on an outer side of said bracket;
• said sound absorber detachably inserted along said platen;
• said printing sheet guide releasably brought into engagement at corners on opposite sides with said first engaging portions of said brackets so that the printing sheet guide can be set in a predetermined position or brought to a lying position when not in use;
• said noise silencing cover releasably brought into engagement at forward ends of arms located on opposite sides of said noise silencing cover with said second engaging portions of said brackets to thereby cover a printing section in a manner to be freely opened and closed;
• and
• said page feeder including engaging portions located on opposite sides of said page feeder which are inserted in positions at the front cover outwardly of the sound absorber and the noise silencing cover and inwardly of said hinged portions in such a manner that said engaging portions are releasably brought into engagment with a shaft of said platen;
• wherein said components to be optionally mounted on the printing apparatus can be mounted either singly or plurally in any arbitrarily selected combination as desired, and the front cover can be brought to an open position without removing the optionally mounted component or components for replacing a ribbon or a printing wheel with a new one.
