Summary of the Invention The invention is directed to an inking mechanism for a printer in which a traveling inker alternately contacts an ink cartridge and the printing members of a print head. The cartridge is yieldably mounted to the movable one of the print head and a cooperable platen. When the inker contacts the ink cartridge, the mounting means for the ink -~
cartridge yields. ~ore specifically the ink cartridge can cant out of its normal disposition so that the inker contacts the cartridge with more unîform pressure than with the inking mechanisms o the prior art. The ink cartridge is contacted by a spring which is preferably a very light spring so that the cartridge will yield readily. According to the invention~
mounting means including supports are formed integrally with the print head in one embodiment and as part of a bracket in another embodiment. In both embodiments, a pair of cutouts are illustrated as being provided for holding the ink cartridge în a home position. The ink cartridge is held captive in the cutouts but a spent cartridge is readily removed and replaceable with a new cartridge. The force of the spring is adjustable by shifting the spring relative to the print head. The novel ;
cartridge is provided with four wall panels and an end wall ;~
panel and ink receptive material in the form of a pad is retained ;
by the body of the cartridge. The body is provided with pro-jections which present a line ) contact to the supports to define the home position of the ink cartridge. The body has a manually graspable handle by which the ink cartridge can be inserted and removed. The body, the projections and the handle ~ `
are of one-piece construction and are composed of molded plastics material.

the mechanism for operating print head 11 and feed ~inger 12.
The feed finger 12 is reciprocated across the web W
of labels L which moves across the top of the platen 13. The print head 11 cooperates with the platen 13 to print successive labels L. A bell crank actuat~ng lever 14 is pivotally connected to the ~eed finger 12 by a pin 15. The lever 14 is alternately pivoted clockwise and counterclockwise by a cam (not shown) as in patent No. 2,696,784. The pln 15 also pivotally mounts an :
inker generally indicated at 17. By operation of a cam (not shown) as in patent No. 2,696,784, the print head 11 is alternately raised and lowered. The print head 11 is shown in FIGURE 1 to be in its initial or home position in which the print head 11 is slightly spaced above the platen 13. By operation o~ a crank wheel 18, the print head 11 is raised and immediatel~- thereafter the lever ~, .
14 drives the feed finger 12 and the inker 17 to the right ~rom the position shown in FIGURE 1. As the feed ~inger 12 moves to . .

another label L between the print head 11 and the platen 13. While the print head ll is raised and as the feed finger 12 moves to the right ~FIGURE 1), the inker 17 also moves to the right between the print head 11 and the platen 13.

After the inker 17 and the feed finger 12 ha~e cleared the print head 11, the print head 11 is dri~en toward the label web W. While the print head 11 is moving toward the platen 13, a cartridge 20 moves into contact with the pad 17' of the inker 17. Continued travel of the print head ~:
11 toward the platen after contact of the cartridge 20 with the pad 17' causes projections 39 and 40 to start moving away from ;
suxfaces 23' and 24' against the action of a spring 43. Printing of the label L takes place at the end of travel of the print head 11 toward the platen 13. In the remainder o the machine cycle, the print head 11 moves away from the platen 13 toward its init al position. During ~he ret~urn of the print head 11 to its initial position, the spring 43 returns the cartridge 20 to the position in which the projections 39 and 40 are in contact with surfaces 23' and 24' of the respective supports 23 and 24.
In the apparatus according to patent No. 2,696,784, the inker was inked by the user who appliea ink from a bottle to the ink pad of the inker. In accordance with the present invention, the ink cartridge generally indicated at 20 is both resiliently and readily remo~ably mounted to the print head 11.
The print head 11 is comprised of a pair of frame members 21 and 22 which mount printing members 19 in the form of endless printing bands. A detailed disclosure of the print head 11 is shown in Canadian patent No. 653,495.
