Abstract

PURPOSE: To accomplish the swift setting of the code number with a less malfunctioning by a mechanism of simultaneously driving the particular rotation part selectively retained and the check digit setting rotation part equipped corresponding thereto.

CONSTITUTION: In the case of the code number (67843), the selective rotation shaft 12 is pulled to retain the code indication 2, and the knob 12A is turned to (00003). The CD indication member 1 rotates together to indicate the numeral (9) corresponding to the code number (3) of the unit digit. In this case, other code indication members 3W6 fail to rotate retained by the indication position specifying mechanisms 17CW17F. The numeral (9) indicated by the CD indication member means the check digit corresponding to the numeral (3) of one figure. Then, after the code indication member 3 is retained to give the numeral (4) of tens digit, it rotates by 8/10 in the positive direction while the indication member 1 rotates by the same degree with the numeral (9) already indicated as the reference to indicate the numeral (7). This means the check digit of the code number (43). The same prosedure is repeated.
