With reference to the figure, a concept for a print wheel and print wheel cartridge is disclosed, which features keyed interlocks for positive print wheel location and

retention while the print wheel is located within the cartridge. One wall of a print wheel cartridge 10 is disclosed in relationship to the print wheel motor shaft 12, mounting hub 14 with integral alignment lug 16, mounting means 18 and the hub

section of a print wheel 20. Either molded or inserted double~actiondetents 22 on print wheel 20, cooperating with corresponding apertures 24 in the wall of print wheel cartridge 10, provide the alignment and locking feature between the print wheel 20 and cartridge 10. Alignment between the print wheel motor shaft 12 and

the print wheel 20 is provided by alignment lug 16 cooperating with aperture 26.

Locking between the print wheel motor shaft 12 and the print wheel 20 is provided by the inter~action of mounting means 18 and spring detent 28 in the hub of print wheel 20,

In operation, the print wheel motor and shaft are moved toward the print wheel 20

located in cartridge 10, whereupon the print wheel 20 is locked to the mounting means 18 on the shaft 12 of the print wheel motor by detent 28. The print wheel 20 is aligned properly by alignment lug 16 cooperating with aperture 26. Upon further movement, the print wheel 20 i...
