Impact printer having readily replaceable rotary print member.

摘要

An impact printer is provided having a rotatably mounted print member (22) such as a daisy wheel member which has an array of characters (27) arranged around its periphery and a print hammer (32) operable to impact selected ones of said type characters against a printing medium (13) at a selected print position (26). The print member is readily removable and replaceable without moving the print hammer or any other significant portion of the printer apparatus through the expedient of mounting the print member in a position whereat the curve of rotation formed by rotating each selected character through the print position extends above the print position. With this arrangement, the print member may be easily removed and replaced without moving the standard print hammer assembly (31) which does not extend substantially above the print position.
