ABSTRACT:
The disclosure concerns an index wheel for use in a printing device. The device includes a plurality of type wheels which are coaxially juxtaposed to one another in independently rotatable manner. The outer circumference of each type wheel carries a multiplicity of lands respectively bearing types. The outer circumference of the type wheel also has a multiplicity of engagement grooves, each formed between two adjacent lands. An index wheel of the invention is engageable with each type wheel to rotationally drive the type wheel when the index wheel is manually rotated through a selecting shaft by means of a selecting knob. The index wheel includes a ring-shaped body. A multiplicity of teeth are formed on the outer circumference of the ring-shaped body and are circumferentially spaced such that they engage with the engagement grooves of the respective type wheel. A multiplicity of index letters are respectively borne on the outer circumference of the ring-shaped body between any two adjacent teeth. According to the invention, the index letters are formed by a printing method, including a hot-stamping process.
