De-coupleable print position indicator

Year	Description
1994	Invention patented by Darrell K. Chan and Chihsin S. Young on June 7th, 1994. Abstract: A print position indicator is coupleable to and uncoupleable from a print head so that the print position indicator can continuously indicate the next print position even when the print head is not adjacent that position. The print position indicator is slidably mounted on the same guide rail that carries the print head for left-and-right movement and includes a coupling mechanism so that the print position indicator can be detached from the print head when the print head returns to a home position, leaving the print position indicator correctly pointing to the next print position. In addition, the print position indicator can include plural laterally extending indicators, such as a row of light-emitting diodes (LED's) which are sequentially activated so as to indicate the next print position when plural characters are input before any of them are printed.
