Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
An improved printer apparatus, comprising: receptor material supply means for supplying a receptor material; ribbon supply means for supplying a ribbon material, the ribbon material including a plurality of different colored sections, reoccurring in a repetitive pattern; a print head and platen arrangement, the receptor material and the ribbon material extending intermediate of the print head and the platen in a juxtaposed relationship with the print ribbon being disposed intermediate of the receptor material and the print head; means for advancing the receptor material; and a ribbon material takeup roller assembly having means to advance the ribbon material, the roller assembly including slip clutch drive means for permitting advancement of the ribbon material during the printing process when tension on the ribbon material is less than a predetermined value and the roller assembly further including direct drive means bypassing the slip clutch means for permitting advancement of the ribbon material from one colored section to the next.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
58 words
An apparatus according to claim 1, wherein the ribbon material takeup roller assembly includes a solenoid motor interconnected to a takeup roller of the ribbon material takeup roller assembly by two different linkages, one of said linkages including the slip clutch means and the other of said linkages including the direct drive means bypassing said slip clutch means.
Claim 4
Dependent Claim
40 words
An apparatus according to claim 1, wherein the ribbon material takeup assembly is driven by a first stepper motor during the printing process and a second stepper motor when advancing the ribbon material form one color section to the next.
Claim 5
Dependent Claim
20 words
An apparatus according to claim 1, including control means for rotating the ribbon material takeup roller assembly at variable speeds.
Claim 6
Dependent Claim
28 words
An apparatus according to claim 4, wherein the ribbon material takeup roller rotation rate is varied as an increasingly greater amount of the ribbon material is taken up.
Claim 7
Dependent Claim
22 words
An apparatus according to claim 5, wherein the rate of advance of the ribbon material is sufficient to takeup the ribbon material.
Claim 8
Dependent Claim
103 words
An apparatus according to claim 4, further including sensor means for sensing speed at which the ribbon material is being advanced by the ribbon material takeup roller when the ribbon material is advanced from one color section to the next, the control means being electrically connected to said sensor means for receiving electrical signals from the sensor means representative of the speed at which the ribbon material is being advanced by the ribbon material takeup roller assembly, the control means including program means for processing the electrical signals and determining the rate at which the ribbon material takeup roller assembly should be rotated.
Claim 9
Dependent Claim
24 words
An apparatus according to claim 1, wherein the print head is adjustably mounted so as to enable dot line adjustment of the print head.
Claim 10
Dependent Claim
42 words
An apparatus according to claim 1, wherein the means for advancing the receptor material includes a generally U-shaped clamp for engaging the receptor material, the U-shaped clamp, being mounted for pivotal motion about an axis extending generally longitudinally of the receptor material.
Claim 11
Dependent Claim
20 words
An apparatus according to claim 1, further including cutter means for cutting off an end portion of the receptor material.
