Abstract

Abstract PURPOSE: To use the whole circumference of a torus-shaped character ring, to openings thereof characters and figures are arranged, by loosely attaching the character ring and an annular operation lever at the outside of a lifting circular body. CONSTITUTION: An annular operation lever 11 is contacted with a torus-shaped character ring 5 to openings thereof characters and figures are arranged, one circular notch 12 is formed to the inner edge, and V-shaped notches 14 are made up in response to each character hole 13 over the whole circumference of an inner surface of the character ring 5. A coil spring 16 and a set pin 17 are inserted into a concave hole 15 formed to a lifting circular body 6, and an edge-shaped nose section 18 of the pin 17 is entered into the notch 12 and the notches 14 in common. The annular operation lever 11 is turned until a colliding and contacting pipes 22 contacts with a stopper 23 spanned over an upper section of the character ring 5, the pin 17 is detached from the notch 12 and pushed down, the pin 17 is kept apart from the notches 14 and made free, the desired character is located just above a boring needle, the lever 11 is returned to the original position, the nose 18 of the pin is fitted to the notches 12, 14 and the character ring is stopped.
