Title (EN) INK DELIVERY APPARATUS FOR A DOT MATRIX PRINTER
(FR) APPAREIL D"APPROVISIONNEMENT D"ENCRE POUR UNE MATRICE IMPRIMANTE A POINTS
Abstract: front page image
(EN)A matrix printer having reciprocating print wires (12). The printing tips are arranged within a bearing (22). Ink is stored within a container (4) below the print heads. Wicks (44, 74, 75) deliver the ink from the container to the print wires by capillary action, depositing ink upon the sides of the print wires. The ink moves through the jewel bearing (22) and on to the printing tips and is transferred to the paper (15) by the tips. Porous absorbers (78, 79) expand upon wetting, to engage the print wires to regulate the flow of ink and prevent dripping or dribbling of the ink and to prevent the ink from travelling rearwardly along the print wires toward the print wire actuating means. The wicks are mounted in a holder (73) removably inserted into the nose (13) facilitating assembly and disassembly for replacement of the wicks (74, 75) and the porous absorbent means (78, 79). A separator tool (81) retains the wicks (74, 75) in position for proper insertion. The disposable container (40) is releasably mounted on a support (30) adjacent to the print head for ease of removal and replacement.
(FR)Une matrice imprimante possede des fils imprimants alternatifs (12). Les extremites imprimantes sont contenues dans une portee (22). L"encre est emmagasinee dans un reservoir (4) sous les tetes imprimantes. Des meches (44, 74, 75) amenent l"encre du reservoir aux fils imprimants par capillarite, deposant l"encre sur les cotes des fils imprimants. L"encre passe au travers des portees a rubis (22) puis sur les pointes imprimantes et est transferee sur le papier (15) par ces pointes. Des corps absorbants poreux (78, 79) se gonflent en s"humidifiant pour engager les fils imprimants afin de regler le debit d"encre et eviter qu"elle ne bave ou s"egoutte et l"empecher de revenir en arriere le long des fils imprimants vers les moyens d"actionnement des fils imprimants. Les meches sont montees dans un porte-meche (73) insere dans le nez (13) de maniere amovible a fin de faciliter le montage et le demontage lors du changement des meches (74, 75) et des moyens absorbants poreux (78, 79). Un outil separateur (81) maintient les meches en position afin de faciliter leur insertion correcte. Le recipient jetable (40) est monte de maniere liberable sur un support (30) adjacent a la tete imprimante afin d"en faciliter le demontage et le remplacement.
