Abstract

Disclosed is a print (daisy) wheel that has type fonts on both sides of the petals of the print wheel. This will allow multiple fonts on a single wheel, or a replication of the same font on the print wheel. By employing type on both sides of the print wheel, a reduction in manufacturing costs and reduced storage area of the different type wheels and fonts may be attained.

Reversible Print Wheel

Disclosed is a print (daisy) wheel that has type fonts on both sides of the petals of the print wheel. This will allow multiple fonts on a single wheel, or a replication of the same font on the print wheel. By employing type on both sides of the print wheel, a reduction in manufacturing costs and reduced storage area of the different type wheels and fonts may be attained.

Turning now to the drawing, and especially Fig. 1 thereof, a typical print wheel 10 operating in conjunction with a hammer 20, selection motor 30 and indexing platen 35 is illustrated therein. The print wheel 10 comprises a plurality of spokes 11 which radiate from a hub 12 which includes a keyway or the like 13 for receiving a key 31 on the shaft 32 of the selection motor 30.

At the terminal ends of the spokes 11 are type carriers 14 which contain on their forward face 15 a first type font, and on their second face 16 a second type, character or indicia representative of a second type font. Immediately above and below the type carrier 14 are impact receivers 17 and 18, respectively, which are positioned such that the impact by the hammer 20 does not effect an impact upon the character or indicia on the surface 16, which otherwise would make that font unusable.

The design of the hammer 20 is straightforward, and includes a conventional solenoid 21 and shaft 22 with a bifurcated anvil portion 23 having spaced-apart legs 24 and 25 thereon adapted to register with the Impact...
