Abstract
Abstract A plurality of printing components each are attached to a movable transport means to extend along a line of print with respect to a recording means. A permanent magnet is attached to each of said components and an electromagnet is fixed in spaced relationship to said permanent magnets. The permanent magnets having their polarity varying alternately from component to component. The electromagnet is selectively excited with a given polarity to produce a deflection of one or more permanent magnets in the direction of the recording means to cause the print component to print thereon.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
A printer comprising a plurality of deflectable printing components and a recording means, each of said components being attached to a movable transport means adapted to sequentially carry said printing components in a path extending along a line with respect to said recording means, a permanent magnet attached to each of said components to move conjointly therewith and an electromagnet fixed in spaced relationship to the line of movement of said permanent magnets, said permanent magnets being adjacent said recording means, said permanent magnets having their polarity varying alternately from component to component, and means for selectively exciting said electromagnet with a given polarity to produce a force field on at least one permanent magnet to thereby cause deflection of selected printing components in the direction of said recording means to cause said print component to print thereon.
Claim 2
Dependent Claim
138 words
A printer comprising a plurality of deflectable printing components and a recording means, each of said components being attached to a movable transport means adapted to sequentially carry said printing components in a path extending along a line with respect to said recording means, a permanent magnet attached to each of said components to move conjointly therewith and an electromagnet fixed in spaced relationship to the line of movement of said permanent magnets, said permanent magnets being adjacent said recording means, said permanent magnets having their polarity varying alternately from component to component, and means for selectively exciting said electromagnet with a given polarity to produce a force field on at least one permanent magnet to thereby cause deflection of selected printing components in the direction of said recording means to cause said print component to print thereon.
Claim 3
Dependent Claim
59 words
The printer according to claim 1 wherein said electromagnet comprises a pair of spaced poles providing an air gap therebetween in which said permanent magnet may move, said poles having a length such that the gap extends over the permanent magnet of at least one printing component, and an exciter winding arranged about at least one of said poles.
Claim 4
Dependent Claim
21 words
The printer according to claim 2 including means for producing a direct current pulse of selected polarity in said exciter winding.
Claim 5
Dependent Claim
50 words
The printer according to claim 2 wherein said printing components are spaced along said transport means with respect to each other a distance whereby the permanent magents of at least two of said printing components pass through said air gap between the poles of said electromagnet at the same time.
Claim 6
Dependent Claim
42 words
The printer according to claim 1 wherein each of said printing components comprise an elongated resilient arm having printing means at one end and being attached at the other end to said transport means said magnets being arranged between the ends thereof.
Claim 7
Dependent Claim
38 words
The printer according to claim 5 wherein the permanent magnets of said printing components are offset in selected sets between the ends of said arm, and an electromagnet is provided for each of said sets of permanent magnets.
Claim 8
Dependent Claim
34 words
The printer according to claim 6 wherein said electromagnets are arranged in parallel planes between said transport means and said recording means and the magnets of each of the associated sets are coordinated thereto.
Claim 9
Dependent Claim
24 words
The printer according to claim 1 wherein said transport means comprises an endless conveyor and said printing components are circulated past said recording means.
Claim 10
Dependent Claim
32 words
The printer according to claim 1 including an ink carrier arranged between said printing components and the recording means to transfer ink to said recording means on deflection of said printing components.
Claim 11
Dependent Claim
19 words
The printer in accordance with claim 1 wherein each of said printing components is provided with a predeterminEd symbol.
Claim 12
Dependent Claim
32 words
The printer according to claim 10 wherein said recording means comprises an elongated sheet movable in a direction normal to the movement of said transport means and means for moving said sheet.
Claim 13
Dependent Claim
46 words
The printer according to claim 1 including an ink carrier spaced from said recording means along the path of travel of said printing components and one of said electromagnet being operable on excitation to deflect said printing components toward said ink carrier to be inked thereby.
