Abstract
Abstract A desk-top and/or hand held thermal printer comprises a main unit having a guide path therein for a moving continuous label strip which includes a backing sheet and discrete labels detachably attached to the backing sheet. The printer has a flat bottom surface for resting on a flat surface; a retaining means for supporting a roll of backing sheet and labels and guiding the labels through a thermal printing device where a bar code or the like is thermally printed on the thermosensitive labels; a label peeling means for peeling the labels from the backing sheet; a label affixing means for affixing the peeled-off labels on objects; a data input means for example a keyboard or a computer input terminal; a data display means; and a controller for controlling the entire printer.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
286 words
A desk-top thermal printer for printing labels, comprising: a housing having outer dimensions which are small enough to enable the printer to be transported and operated by a single operator, the housing having a flat bottom surface for supporting the printer, during use thereof, on a selected flat surface, the printer being operable while being supported on the flat surface; retaining means for supporting a roll of labels which includes an elongate continuous backing sheet and a plurality of discrete unprinted labels which are detachably attached to the backing sheet and which follow one another along the length of the backing sheet; a thermal printer head for printing information on the labels and a defined guiding path in the housing for the backing sheet; a label detector positioned ahead of the printer head for detecting each approaching label; means for transporting the backing sheet through the printer head; peeling means located past the printer head for separating each label from the backing sheet after the passage thereof through the printer head and depositing each printed label outside the housing; label receiving and supporting means for holding each separated label in a manner which is effective to enable the separated label to be applied to an object to be marked by (a) drawing the object against the label supporting means, (b) holding the printer in hand and applying the separated label to the object with the printer or (c) removing the label by hand from the label supporting means and applying same to the object; and control means coupled to the print head, the label detector and to the transporting means for actuating, controlling and coordinating the operation of the printer head, label detector and transporting means.
Claim 2
Dependent Claim
286 words
A desk-top thermal printer for printing labels, comprising: a housing having outer dimensions which are small enough to enable the printer to be transported and operated by a single operator, the housing having a flat bottom surface for supporting the printer, during use thereof, on a selected flat surface, the printer being operable while being supported on the flat surface; retaining means for supporting a roll of labels which includes an elongate continuous backing sheet and a plurality of discrete unprinted labels which are detachably attached to the backing sheet and which follow one another along the length of the backing sheet; a thermal printer head for printing information on the labels and a defined guiding path in the housing for the backing sheet; a label detector positioned ahead of the printer head for detecting each approaching label; means for transporting the backing sheet through the printer head; peeling means located past the printer head for separating each label from the backing sheet after the passage thereof through the printer head and depositing each printed label outside the housing; label receiving and supporting means for holding each separated label in a manner which is effective to enable the separated label to be applied to an object to be marked by (a) drawing the object against the label supporting means, (b) holding the printer in hand and applying the separated label to the object with the printer or (c) removing the label by hand from the label supporting means and applying same to the object; and control means coupled to the print head, the label detector and to the transporting means for actuating, controlling and coordinating the operation of the printer head, label detector and transporting means.
Claim 3
Dependent Claim
51 words
A desk-top thermal printer according to claim 1 in which the transporting means comprises a driver roller which is engageable with the roll of labels for transportation thereof, a stepping motor and a timing belt which couples the stepping motor to the drive roller for effecting rotation of the drive roller.
Claim 4
Dependent Claim
53 words
A desk-top thermal printer according to claim 2 further comprising at least one start switch coupled to the control means, the control means including means for advancing the roll of labels by one label at a time in response to each activation of the start switch and an output from the label detector.
Claim 5
Dependent Claim
25 words
