Abstract
Abstract Printing apparatus is provided in which an entire line of print is printed at one time and wherein a sheet of paper is advanced past a printing station so that a series of lines of printing can be successively printed thereon. The printing is effected in a plurality of parallel columns, with which are aligned a like number of belts on which are located the print characters. These belts are driven by one or more drums in repetitive cycles. In one embodiment, each of the belts is brought to a halt with the desired character at the printing line at the printing station and when a line of print has been thusly compiled, a single hammer unit drives the characters against a ribbon to print the line on the paper. The belts are then returned to an initial position of rest in preparation for the next succeeding cycle for the next succeeding line of print. The print hammer may be actuated from the same source of power which drives the drum or drums and there may be related to this source of power a stepping device which steps the paper through the printing station. As an alternative, a plurality of parallel belts are selectively released to be driven by a drum such that the desired characters for a line of print are brought to a printing station in unison.

Claim 1
Independent Claim
213 words
Printing apparatus for printing on a sheet of record medium adapted for being displaced through a printing station in a determinable direction to enable a line-by-line printing on said sheet in lines perpendicular to said direction and in a multitude of parallel columns aligned with said direction, a plurality of belts parallel to said columns and corresponding in number thereto, said belts including like assortments of print characters serially distributed along corresponding lengths of said belts, drive means adapted for driving each of said lengths through said station, locating means operatively associated with said belts to prevent movement thereof through said station but to release the belts selectively so that preselected print characters are brought simultaneously to a printing line at said station in each of said columns to compile a line of print characters, and print means to displace the thusly compiled line of print characters and said sheet together to print an entire line all at one time, said drive means including a drum adapted for driving said belts and said locating means including means releasably engaging the belts to prevent the latter from moving with the drum until respectively and selectively released whereupon the belts move with the drum and the preselected print characters pass through said printing station simultaneously.

Claim 3
Dependent Claim
34 words
Printing apparatus as claimed in claim 14, wherein said locating means includes means controlling the release of the respective belts to enable said compiled line of print characters to reach said print line simultaneously.
Claim 4
Dependent Claim
16 words
Printing apparatus as claimed in claim 2, wherein said belts encircle and frictionally engage said drum.
Claim 5
Dependent Claim
50 words
Printing apparatus as claimed in claim 2, wherein said print means includes anvil means inside said drum and a print roller external of said drum in cooperating relationship with said anvil means, said apparatus further including means to drive the drum and roller with at least substantially equal peripheral speeds.
Claim 6
Dependent Claim
32 words
Printing apparatus as claimed in claim 4 comprising means to displace said roller to an inoperative position spaced from said drum and means for selectively retaining the roller in said operative position.
Claim 7
Dependent Claim
19 words
Printing apparatus as claimed in claim 4 comprising a lobe on said roller to cooperate with said anvil means.
Claim 8
Dependent Claim
29 words
Printing apparatus as claimed in claim 4, wherein said belts include positioning lobes, said anvil means having a shape to accommodate the positioning lobes for accurately positioning the characters.
Claim 9
Dependent Claim
27 words
Printing apparatus as claimed in claim 2, comprising stops on said belts, said locating means including latches corresponding to said stops and solenoids to operate said latches.
Claim 10
Dependent Claim
32 words
Printing apparatus as claimed in claim 8, comprising parallel strips connecting said latches to said solenoids, said solenoids including operating members engaging the strips and reeds supporting the operating members for displacement.
Claim 11
Dependent Claim
54 words
Printing apparatus as claimed in claim 4, comprising means for displacing the print roller to an inoperative position spaced from said drum and for bringing the print roller into cooperating relationship with said anvil means during alternate rotations of the drum between which the belts are reset to starting positions by said locating means.
