Abstract
Abstract This invention is concerned with a mosaic printer, for example, of the needle print head type which comprises a stationary print head and means for feeding an article, for example a web of paper to be printed, in a direction orthogonal to a row of print devices of the head and in synchronism with operation of the print devices so that, by selective operation of the print devices, the article is provided by the print devices with a pattern which constitutes visual data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
A mosaic printer, comprising, stationary print head means including a plurality of needle print heads arranged in a row, means for feeding a ticket web one ticket length at a time to be printed with equispaced repeat ticket lengths in a direction orthogonal to the row of needle print heads, the print heads being arranged so that impact thereof causes visible dots to be formed on the surface of the web in a pattern which constitutes visual data, the web having holes therein spaced in the feed direction of the web, the feeding means comprising a drive motor, a rotatable drive member driven by the drive motor for engaging the web to thereby feed the web, said drive member comprising a rotatable drive disc having a flange extending radially of a portion of the periphery of the disc, and a one-revolution clutch connected between the motor and the drive member for driving the web for the one ticket length thereof, the clutch being arranged so that the drive disc feeds the web until one of the holes therein is located adjacent the drive disc whereupon the feeding is halted until the flange engages the sides of the one hole to drive the web for the one ticket length thereof.
Claim 2
Dependent Claim
209 words
A mosaic printer, comprising, stationary print head means including a plurality of needle print heads arranged in a row, means for feeding a ticket web one ticket length at a time to be printed with equispaced repeat ticket lengths in a direction orthogonal to the row of needle print heads, the print heads being arranged so that impact thereof causes visible dots to be formed on the surface of the web in a pattern which constitutes visual data, the web having holes therein spaced in the feed direction of the web, the feeding means comprising a drive motor, a rotatable drive member driven by the drive motor for engaging the web to thereby feed the web, said drive member comprising a rotatable drive disc having a flange extending radially of a portion of the periphery of the disc, and a one-revolution clutch connected between the motor and the drive member for driving the web for the one ticket length thereof, the clutch being arranged so that the drive disc feeds the web until one of the holes therein is located adjacent the drive disc whereupon the feeding is halted until the flange engages the sides of the one hole to drive the web for the one ticket length thereof.
Claim 3
Dependent Claim
47 words
A mosaic printer according to claim 1 wherein there is provided a timing device operable in synchronism with the drive disc, the timing device controlling operation of the needle print heads so that operation of the needle print heads is synchronised with feeding of the ticket web.
Claim 4
Dependent Claim
85 words
A mosaic printer according to claim 2 wherein there is provided an ink ribbon, at least a portion of which extends between the web and the print heads across the feed direction of the web, said ink ribbon portion being arranged so that impact of the needle print heads causes patterns of a surface of the web and the ink ribbon to be brought into contact with one another thereby forming dots of ink on the surface of the web which together form the pattern.
Claim 5
Dependent Claim
51 words
A mosaic printer according to claim 3 wherein the longitudinal axis of said portion of the ribbon which extends across the feed direction of the web is diagonal to a plane passing through the portion and extending perpendicular to the upper surface of the portion and transversely of the feed direction.
Claim 6
Dependent Claim
47 words
A mosaic printer according to claim 2 wherein an inked roller which is barrel shaped in cross section is provided on one side of the web and the needle print heads arranged in an arc above the roller are provided on the opposite side of the web.
Claim 7
Dependent Claim
46 words
A mosaic printer according to claim 1 wherein there is provided a guillotine operable in synchronism with the web feeding means and with the needle print heads so that the web may be cut into sheets as the web moves away from the needle print heads.
