ABSTRACT:
An electric numbering machine which continuously prints a number of large figures by use of a single figure wheel, is compact in size, and reduces the printing operation time. A case of the machine is provided therein with a shaft interposed between a pair of support plates rocked by operation of a solenoid, and rotated by a pulse motor; a figure wheel fitted to the shaft to rotate integrally with same; a ratchet intermittently rotated by operation of the solenoid via a feed mechanism; a brake pawl cooperating with the ratchet to restrict return rotation of the ratchet; a drum cooperating with the ratchet to rotate integrally therewith; and a tensile member having one end fixed to the drum and the other end fixed to a support of the figure wheel. The figure wheel is moved by the tensile member one figure at a time along the shaft against resiliency of an elastic member, and a release member is provided so as to release engagement of the feed mechanism and the brake pawl with the ratchet so as to return the figure wheel to the start position thereof after rocking and movement of the figure wheel is repeated to print the number of digits of predetermined figures and after printing is complete. Various buttons including figure buttons for inputting and setting the number to be printed and instruction buttons for generating various print instructions are disposed on the case.
