Inking apparatus

In a base-supported printing device for use in a document processor, wherein it is required that a coating of ink be applied to one or more rotatably operable print producing elements of the device for each printing cycle, improved ink applying means comprising:

• (a) an inked roller rotatably mounted within a cutaway cartridge having a central aperture such that a predetermined arcuate portion thereof is exposed,
• (b) means for mounting said cartridge in contiguous relationship with said print producing elements and such that said exposed arcuate portion of said inked roller is limitably disposed in juxtaposed relationship therewith, said mounting means including a cartridge supporting plate pivotally connected along a predetermined side edge thereof to said base of said printing device, said cartridge supporting plate being provided with a cartridge mounting post adjacent the pivotal connection between said plate and said base, a pair of spaced apart cartridge limit pins disposed along the end of said cartridge supporting plate interfacing with said print producing elements, a first arcuate slot disposed adjacent the end of said cartridge supporting plate remote from said interfacing end, a cammable pin disposed adjacent a predetermined end of said first arcuate slot, a second arcuate slot disposed intermediate said first arcuate slot and said cartridge mounting post, and a mounting post fixed to said cartridge supporting plate said post extending coaxially through said central aperture of said cartridge, and
• (c) means for pivotally and retainably adjusting said mounting means relative to said base such that a predetermined minimal frictional contact is established between the exposed arcuate portion of said inked roller and said print producing elements, said frictional contact being effective to deposit a coating of ink on said print producing elements during the terminal phase of their operable rotation in each printing cycle.
