US4388628A — Multi-color thermal transfer recorder

Claim 1

Independent Claim 114 words

A multi-color, thermal transfer, recorder wherein a plurality of single-color images different in color from each other are recorded in superimposed fashion on a recording sheet producing an image in multiple colors, comprising: a thermal recording head; a roll disposed in an opposing relation to said thermal recording head; an ink donor sheet adapted to travel through a contacting portion between said thermal recording head and said roll opposing said recording head; and said ink donor sheet having two or more layers of single-color ink different in color from each other, each of said two or more ink layers having a length equal to a length of an outer circumference of said opposing roll.

Claim 2

Dependent Claim 114 words

A multi-color, thermal transfer, recorder wherein a plurality of single-color images different in color from each other are recorded in superimposed fashion on a recording sheet producing an image in multiple colors, comprising: a thermal recording head; a roll disposed in an opposing relation to said thermal recording head; an ink donor sheet adapted to travel through a contacting portion between said thermal recording head and said roll opposing said recording head; and said ink donor sheet having two or more layers of single-color ink different in color from each other, each of said two or more ink layers having a length equal to a length of an outer circumference of said opposing roll.

Claim 3

Dependent Claim 24 words

The recorder claimed in claim 1 further comprising a clip attached to said opposing roll for winding said recording sheet onto said opposing roll.

Claim 4

Dependent Claim 38 words

The recorder claimed in claim 2 further comprising a stripping finger for separating and removing said recording sheet from said opposing roll after said plurality of single-color images different in color have been recorded on said recording sheet.

Claim 5

Dependent Claim 60 words

The recorder claimed in claim 3 further comprising a supply reel and a take-up reel, said ink donor sheet being transported from said supply reel, through said contacting portion between said thermal recording head and said opposing roll to said take-up reel, and first and second idler means for guiding said ink donor sheet to and from said opposing roll.

Claim 6

Dependent Claim 48 words

The recorder claimed in claim 4 wherein said first and second sets of idler means are adjacent to said opposing roll so that said ink donor sheet passing between said first and second sets of idler means is adjacent to a bottom circumference section of said opposing roll.

Claim 7

Dependent Claim 24 words

The recorder claimed in claim 1 or 5 wherein said opposing roll is covered by a rubber sheet over an entire peripheral surface thereof.

Claim 8

Dependent Claim 48 words

The recorder claimed in claim 1 further comprising a second roll and a belt, said second roll being connected to said opposing roll by said belt, each of said two or more ink layers having a length equal to a length of an outer circumference of said belt.

Claim 9

Dependent Claim 22 words

The recorder claimed in claim 7 further comprising a clip attached to said belt for winding said recording sheet onto said belt.

Claim 10

Dependent Claim 37 words

The recorder claimed in claim 8 further comprising a stripping finger for separating and removing said recording sheet from said belt after said plurality of single-color images different in color have been recorded on said recording sheet.

Claim 11

Dependent Claim 60 words

The recorder claimed in claim 1, 2, 3, 4, 5 or 9 wherein said ink donor sheet has multiple layers of ink formed thereon so that every color has a high melting point allowing the amount of ink being transferred to said recording sheet to vary depending upon the amount of heat energy being applied to said thermal recording head.

Claim 12

Dependent Claim 122 words

A multi-color, thermal transfer, recorder wherein a plurality of single-color images different in color from each other are recorded in a superimposed fashion on a recording sheet producing an image in multiple colors, comprising: a thermal recording head; a roll disposed in an opposing relation to said thermal recording head; an ink donor sheet adapted to travel through a contacting portion between said thermal recording head and said roll opposing said recording head; and said ink donor sheet having two or more layers of single-color ink different in color from each other, said two or more layers of single-color ink being disposed adjacent to one another and each of said layers extending across an entire width portion of said ink donor sheet.

Claim 13

Dependent Claim 122 words

A multi-color, thermal transfer, recorder wherein a plurality of single-color images different in color from each other are recorded in a superimposed fashion on a recording sheet producing an image in multiple colors, comprising: a thermal recording head; a roll disposed in an opposing relation to said thermal recording head; an ink donor sheet adapted to travel through a contacting portion between said thermal recording head and said roll opposing said recording head; and said ink donor sheet having two or more layers of single-color ink different in color from each other, said two or more layers of single-color ink being disposed adjacent to one another and each of said layers extending across an entire width portion of said ink donor sheet.
