<p>The rewinding hub 5 of this cartridge is only driven during printing. The printer provides this driving by causing a drive and tension hub 10 to rotate, against which a leaf spring 24 is pressed. This hub 10 causes the rewinding hub 5 to rotate via two pulleys 9, 7 and one belt 8. The traction exerted on the inking ribbon 6, for the purpose of running it past, causes a lever 18 with a tooth 17 to pivot which, other than printing, immobilises the unspooling hub 4 via its engagement in teeth 16 carried by this hub. <IMAGE></p> |
