Abstract A printing apparatus for use in printing with inks having a relatively highly volatile vehicle onto selected areas of a record sheet includes an ink storing means mounted for movement between a normal position and a remote position and comprises a porous absorbent material substantially enclosed in a body portion having a limited access opening disposed therein for admitting a printing means in ink contacting engagements. The printing means is mounted for movement between a normal position and a printing position. An actuating means is operatively associated with the ink storing means and the printing means for producing a coordinated cyclical movement of the printing means and the ink storing means from their normal positions to the respective printing position and the remote position non-interferingly through interfering paths such that the ink storing means moves out of the path of the printing means before the printing means moves from the normal position to the printing position and the printing means returns to the normal position before the ink storing means returns to its normal position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
In a printing apparatus having a frame and a means for supporting a print receiving sheet at a work station: the improvement comprising a substantially closed printing fluid reservoir means; means mounting said reservoir means for pivotal movement about a first axis; a print arm having a printing tip; means mounting said print arm for pivotal movement about a second axis; stop means for determining the normal positions of said reservoir means and said print arm, said positions being such that the printing tip of said arm then extends through an aperture formed in said reservoir means; and drive actuating means for sequentially pivotally actuating said print arm and said reservoir means; said drive means including a linkage for initiating one of said pivotal movements before initiating the other of said pivotal movements.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
41 words
Apparatus as defined by claim 1 wherein said drive actuating means includes a common driven shaft and a plurality of crank means which when operated serve to pivotally actuate said reservoir means before initiating the pivotal actuation of said print arm.
Claim 4
Dependent Claim
17 words
Apparatus as defined by claim 1 wherein said print arm is spring biased to its normal position.
