Abstract

A rotatable print wheel has a character petal which is to be printed positioned one petal position prior to its print position for application of ink to the petal by an ink applicator pivoted into engagement with the petal. The petal is then moved to the print position with the ink thereon and prints the selected character. (Image Omitted) A printer 1 (Fig. 1) includes a carriage 2 having a rotatable print wheel 3 with character petals 4 thereon. Prior to the selected character petal 4 reaching its print position 5 (Fig. 2), it is disposed at an inking position 6, which is offset one petal position from the print position 5, in front of an ink sponge applicator 7 of a pivotally mounted, ink reservoir applicator 8. The applicator 8 is preferably a cartridge 9 (Fig.

Operator-Insertable Ink Reservoir-Applicator System

A rotatable print wheel has a character petal which is to be printed positioned one petal position prior to its print position for application of ink to the petal by an ink applicator pivoted into engagement with the petal. The petal is then moved to the print position with the ink thereon and prints the selected character.

A printer 1 (Fig. 1) includes a carriage 2 having a rotatable print wheel 3 with character petals 4 thereon. Prior to the selected character petal 4 reaching its print position 5 (Fig. 2), it is disposed at an inking position 6, which is offset one petal position from the print position 5, in front of an ink sponge applicator 7 of a pivotally mounted, ink reservoir applicator 8. The applicator 8 is preferably a cartridge 9 (Fig. 3) mounted on a support shaft 10, which has bearings 11 at its opposite ends for pivotally mounting the support shaft 10 on the carriage 2 (Fig.
1). The cartridge 9 (Fig. 3) has wicking material 12 between a pair of parallel walls 13 and 14. The wicking material 12 includes ink, and transports the ink to the ink sponge applicator 7. The walls 13 and 14 can be ultrasonically welded to seal the ink and the wicking material 12. One of the walls 13 and 14 is preferably integral with the remainder of the cartridge 9 rather than being ultrasonically welded. When the petal 4 (Fig. 1) of the wheel 3 is at the inking position 6 (Fig.
2), a solenoid 15 (Fig. 1) is energized to pivot the support shaft 10 (Fig. 3) of the pivotally mounted applicator 8 about the bearings 11 so that the ink sponge applicator 7, which has a support shoe 16 (Fig. 1) on its side remote from the petal 4, engages the petal 4. If desired, a...
