Abstract
Abstract A thermal printer, particularly for labels, of the type using a continuous band of heat-sensitive material (19) to print on a paper web (5), the band of heat-sensitive material (19) and the paper web (5) being made to pass between a thermal head (10) and a print roller (9), and being driven by separate motors, so that feeding of the band of heat-sensitive material (19) can be stopped at the end of each printing phase, means being provided to move the head (10) away from the roller (9) each time the band of heat-sensitive material (19) is stopped.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
68 words
A process for optimizing use of a band of heat-sensitive material (19) in a thermal printer in which said band of heat-sensitive material and a web of the material to be printed (5) are fed between a thermal head (10) and a print roller (9), characterized in that provision is made for the band of heat-sensitive material (19) to be stopped at the end of each printing phase.
Claim 2
Dependent Claim
68 words
A process for optimizing use of a band of heat-sensitive material (19) in a thermal printer in which said band of heat-sensitive material and a web of the material to be printed (5) are fed between a thermal head (10) and a print roller (9), characterized in that provision is made for the band of heat-sensitive material (19) to be stopped at the end of each printing phase.
Claim 3
Dependent Claim
29 words
A process according to claim 1, characterized in that the band of heat-sensitive material (19) and the web of material to be printed (5) are driven by separate motors.
Claim 4
Dependent Claim
39 words
A process according to claim 1 or 2, characterized in that provision is made for the thermal head (10) to be moved away from print roller (9) each time feeding of the band of heat-sensitive material (19) is stopped.
Claim 5
Dependent Claim
19 words
A process according to claim 3, characterized in that the head (10) is driven by a stepping motor (40).
Claim 6
Dependent Claim
90 words
A thermal printer, of the type using a band of heat-sensitive material (19) to print on a web (5), of paper for example, the band of heat-sensitive material (19) and the web (5) being passed between a thermal head (10) and a print roller (9), characterized in that two separate motors (26, 14) are provided to feed the band of heat-sensitive material (19) and the paper web (5), the motor (26) being blocked to stop feeding of the band of heat-sensitive material (19) at the end of each printing phase.
Claim 7
Dependent Claim
90 words
A thermal printer, of the type using a band of heat-sensitive material (19) to print on a web (5), of paper for example, the band of heat-sensitive material (19) and the web (5) being passed between a thermal head (10) and a print roller (9), characterized in that two separate motors (26, 14) are provided to feed the band of heat-sensitive material (19) and the paper web (5), the motor (26) being blocked to stop feeding of the band of heat-sensitive material (19) at the end of each printing phase.
Claim 8
Dependent Claim
46 words
A printer according to claim 5, characterized in that means are provided for driving the head (10), in particular to move the head (10) away from the print roller (9) each time the motor (26) controlling feeding to the band of heat-sensitive material (19) is stopped.
Claim 9
Dependent Claim
23 words
A printer according to claim 6, characterized in that said means of driving the head (10) are controlled by a stepping motor (40).
Claim 10
Dependent Claim
52 words
A printer according to any one of claims 5 to 7, characterized in that the head (10) is mounted at the end of a lever (32) pivoted around spindle (33) at the other end of which a cam (38) of said stepping motor (40) is brought into engagement by elastic means (35).
Claim 11
Dependent Claim
70 words
A printer according to any one of claims 5 to 8, characterized in that locators (42, 43) are provided to bring the stepping motor (40) into the reset position, these locators consisting in particular of a permanent magnet and a Hall effect sensor, one made fast to the shaft (39) of the stepping motor (40) and the other made fast to the fixed structure of the printer, or vice versa.
Claim 12
Dependent Claim
41 words
A printer according to any one of claims 5 to 9, characterized in that provision is made for a cam (44) acting on a lever (32), that can be operated manually to move the head (10) away from the roller (9).
Claim 13
Dependent Claim
26 words
A printer according to any one of claims 1 to 10, characterized in that the band of heat-sensitive material (19) is loaded into a re-usable cartridge.
Claim 14
Dependent Claim
89 words
A printer according to any one of claims 5 to 11, characterized in that the head (10) is supported on a plate (33) of the lever (32) pivoted around said spindle (31), the bond between the head (10) and the supporting plate (33) being such that the axis of the head can be adjusted in two planes at right angles to each other and both parallel to the axis of the print roller (9), so that it can be brought perfectly parallel to the axis of the roller (9).
Claim 15
Dependent Claim
81 words
A printer according to claim 12, characterized in that a slit (48) is made in said plate (33) parallel to the axis of the print roller (9), open at one end and widening at the other end (50), said skit defining a protruding block (49), to which the head (10) is hinged, the position of the block (49) and thus of the head (10) being adjustable relative to the body of the plate (33) by means of an adjusting screw (51).
