ABSTRACT:
A printer is provided with carriage having a daisy print wheel supporting type elements at the external circumferential edges of respective spokes that make up the wheel. The printer sequentially performs a printing operation by causing its carriage to move in the direction of a printing row and a hammer to strike the designated type element held by an associated print wheel spoke after rotating the designated type element into the printing position. The daisy print wheel includes a number of spokes each mounting a type element at its external circumferential edge. At least one of these spokes is provided with a pen at the position corresponding to that of the type element held by the remaining spokes, and as a result, by selecting the pen from the type element supported in the remaining spokes, either a picture, diagram, or a graph can be optionally drawn, thus effectively realizing a multifunctional printer.
