Abstract

PURPOSE: To provide a letter selective type printer having an improved safety during an abnormal operation and malfunction with high reliability and maintainability by a mechanism wherein a driving method by a cam and a spring is used as a positioning element to align by a pawl.
CONSTITUTION: On completing the selection of a type similar to the method used by the conventional letter selective printer, a positioning element 14 is moved toward an arrow direction by a spring 15. As a groove is provided between the types 2 and 2, the positioning element 14 is inserted to align forcibly the type position at the same position of the respective figure. As the groove 18 is specially forming a taper shape, the positioning element 14 may be inserted smoothly, even the groove is located at the shifted position. Accordingly, a clear print can be obtained without developing displacement of characters in printing. In case of the type 2 being displaced extremely from the printing position, the spring force of a spring 15 is wound up by a cam to release the spring energy at inserting the positioning element 14, resulting in the protection of the printer.
