Abstract

Abstract A printer for preparing labels including coded data is provided with an optical scanner having a plurality of spaced parallel slits in fixed registration with said printed coded data, a scanning slit having a substantially different orientation than said fixed slits and means for translating said scanning slits in a first direction to produce a multiplicity of limited distance scans in a second opposite direction.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 154 words
A code scanning mechanism suitable for use in conjunction with a printer for scanning printed coded indicia immediately following printing of the indicia and while the media supporting the indicia is still retained within the media retaining mechanism of the printer comprising: first means in juxtaposition with said media proximate the printing position, said first means including a plurality of parallel spaced translucent slits in fixed orientation with respect to said media; movable scanning means having a translucent slit having a different orientation than the plurality of parallel translucent slits included in said first means; second means for moving said scanning means to produce relative motion between the scanning means and the first means including the parallel translucent slits; and detector means mounted on said scanning means for providing signals indicative of the reflectivity of the media surface simultaneously visible through the slits in the first means and the slit in the scanning means.
Claim 2
Dependent Claim 154 words
A code scanning mechanism suitable for use in conjunction with a printer for scanning printed coded indicia immediately following printing of the indicia and while the media supporting the indicia is still retained within the media retaining mechanism of the printer comprising: first means in juxtaposition with said media proximate the printing position, said first means including a plurality of parallel spaced translucent slits in fixed orientation with respect to said media; movable scanning means having a translucent slit having a different orientation than the plurality of parallel translucent slits included in said first means; second means for moving said scanning means to produce relative motion between the scanning means and the first means including the parallel translucent slits; and detector means mounted on said scanning means for providing signals indicative of the reflectivity of the media surface simultaneously visible through the slits in the first means and the slit in the scanning means.
Claim 3
Dependent Claim 47 words
A code scanning mechanism as set forth in claim 1 in which the slits in the first means are inclined at an angle to the informational direction of the coded indicia on the media and the slit in the scanning mechanism is inclined in a complementary orientation.
Claim 4
Dependent Claim 30 words
A code scanning mechanism as set forth in claim 2 in which adjacent slits in said first means do not overlap in the direction of informational content of the indicia.
Claim 5
Dependent Claim 35 words
A code scanning mechanism as set forth in claim 3 in which the slit in the scanning means is in coincidence at any give time with only one of the slits in the first means.
