Abstract

PURPOSE: To eliminate a protruded portion on an exterior of a cassette by a method wherein a type wheel is positioned at a home position thereof by an engagement between engaging grooves provided on the casset and engaging protrusions provided at back surface of type portions at finger tips of the type wheel.
CONSTITUTION: When a cassette body 1 is mounted at a predetermined position on a printing device and a shaft 14 of a selection motor 13 is inserted ino the body 1, the shaft 14 is inserted ino a central hold of a type wheel 5. In this case, the shaft 14 pushes a leaf spring 6 and releases a pressing force of the leaf spring 6 against the type wheel 5, concurrently, the type wheel 5 is held at a home position by the shaft 14 due to a function of an engaging protuberance 9 formed at a back surface of a type portion 8 and an engaging groove 7 formed at a wall portion 1a of the body 1, therefore, the shaft 14 and the type wheel 5 can be set in a correct relative position upon mounting the selection motor 13 while a driving pawl 15 and the type wheel 5 are engaged correctly.
