Abstract
Abstract A label printer (1) of the type including two printing devices (2,3) which can issue a label (10) and record paper (29) adjacent each other with printed faces thereof directed forwardly is realised by a specific arrangement of two printing devices and two supply devices without increasing the overall size of the printer. The label printer comprises a first printing device (2) including a first print head (6) mounted for reciprocal pivotal motion and for engagement with an upper face of a first platen (4), a second printing device (3) located within the same vertical planes and generally below the first printing device and including a second print head (9) mounted for reciprocal pivotal motion and for engagement with a lower face of a second platen (7), a first supply means (12) located behind the first printing device (2) for holding a carrier sheet (11) in the form of a roll to which a plurality of labels are applied and for supplying the carrier sheet (11) to the first printing device (2) with the labels (10) directed upwardly, and a second supply means (3) for holding a record paper (29) in the form of a roll with a printing face thereof directed outwardly and for supplying the record paper (29) to the second printing device (3) with the printing face of the record paper directed, downwardly.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
233 words
A label printer (1), comprising: a first printing device (2) including a first print head (6) mounted for reciprocal pivotal motion toward and away from engagement with a face of a first platen (4); a second printing device (3) including a second print head (9) mounted for reciprocal pivotal motion toward and away from engagement with a face of a second platen (7); a first carrier sheet supply means (12) located adjacent said first printing device for holding a carrier sheet (11) in the form of a roll to which a plurality of labels (10) are applied, and supplying the carrier sheet (11) to said first printing device (2) with the labels (10) orientated for printing and dispensed at a first port (28), a second supply means (13) for holding a record paper (29) in the form of a roll with a printing surface, and supplying the record paper (29) to said second printing device (3) with the printing surface of the record paper correctly orientated for printing by said device (3) and dispensed at a second port; characterised in that the first and second printing devices are contained generally within the same vertical planes and in that the first printing device is positioned superior to and displaced relatively rearwardly of, the second printing device, whereby the first and second ports can dispense printed media which is readily viewed from a common viewpoint.
Claim 2
Dependent Claim
233 words
A label printer (1), comprising: a first printing device (2) including a first print head (6) mounted for reciprocal pivotal motion toward and away from engagement with a face of a first platen (4); a second printing device (3) including a second print head (9) mounted for reciprocal pivotal motion toward and away from engagement with a face of a second platen (7); a first carrier sheet supply means (12) located adjacent said first printing device for holding a carrier sheet (11) in the form of a roll to which a plurality of labels (10) are applied, and supplying the carrier sheet (11) to said first printing device (2) with the labels (10) orientated for printing and dispensed at a first port (28), a second supply means (13) for holding a record paper (29) in the form of a roll with a printing surface, and supplying the record paper (29) to said second printing device (3) with the printing surface of the record paper correctly orientated for printing by said device (3) and dispensed at a second port; characterised in that the first and second printing devices are contained generally within the same vertical planes and in that the first printing device is positioned superior to and displaced relatively rearwardly of, the second printing device, whereby the first and second ports can dispense printed media which is readily viewed from a common viewpoint.
Claim 3
Dependent Claim
58 words
A label printer according to claim 1 characterised in that the first and second ports are arranged such that the direction of issuing a label from said first label issuing port and the direction of issuing a record paper (29) from said second record paper discharging port are such that they intersect at a point adjacent the viewpoint.
Claim 4
Dependent Claim
27 words
A label printer according to claim 1 or claim 2 characterised in that the second supply means (13) is located between said first and second printing devices.
Claim 5
Dependent Claim
36 words
A label printer according to any preceding claim characterised in that the first and second platens (4,7) are each respectively driven by the same motor (17) via a respective one-way clutch (20,21) which transmits rotation thereto.
Claim 6
Dependent Claim
30 words
A label printer according to claim 4 characterised in that the one-way clutches 20,21) are located in a coaxial relationship with a rotary drive shaft (18) of the motor (17).
Claim 7
Dependent Claim
53 words
A label printer according to any preceding claim, characterised by a take-up shaft (15) for winding thereon the carrier sheet (11) after it has passed said first printing device (2) which shaft is driven via a torque limiter at a driving force which cannot exceed the driving force driving said first platen (4).
Claim 8
Dependent Claim
