Abstract
Abstract A multicolor recording apparatus includes a number of recording sections for applying different colors of inks. A main transport path travels through all recording sections, while bypass paths are provided for recording sheets which are to be recorded monochromatically, for example, so that any one or more of the recording sections may be bypassed. To eliminate wastage of ink donor sheet, the web containing the solid ink is not conveyed in recording sections bypassed by the sheet.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
A multicolor heat-sensitive recording apparatus having a plurality of recording stations, in each of which an ink donor sheet and a recording sheet placed thereon are run between a heat-sensitive recording head and a pressure roll which is turned while abutting said recording head under pressure, and thermally melting or sublimating ink is thermally transferred onto said recording sheet according to image signals applied to said recording head, comprising; a main sheet conveying path extending through said recording sections; bypass sheet conveying paths which selectively allow a recording sheet to bypass any one or more of said recording sections; and switching means for changing the direction of advance of said recording sheet to cause said recording sheet to advance along said either main sheet conveying path or said bypassing sheet conveying paths, as desired.
Claim 2
Dependent Claim
134 words
A multicolor heat-sensitive recording apparatus having a plurality of recording stations, in each of which an ink donor sheet and a recording sheet placed thereon are run between a heat-sensitive recording head and a pressure roll which is turned while abutting said recording head under pressure, and thermally melting or sublimating ink is thermally transferred onto said recording sheet according to image signals applied to said recording head, comprising; a main sheet conveying path extending through said recording sections; bypass sheet conveying paths which selectively allow a recording sheet to bypass any one or more of said recording sections; and switching means for changing the direction of advance of said recording sheet to cause said recording sheet to advance along said either main sheet conveying path or said bypassing sheet conveying paths, as desired.
Claim 3
Dependent Claim
68 words
A recording apparatus as claimed in claim 1, said main sheet conveying path extending through each of said recording sections, said bypass conveying paths allowing said sheet to pass by selected pressure rolls without passing between said pressure rolls and said recording heads associated therewith, whereby the rotation of said pressure rolls and the transport of said ink donor sheet may be halted for any recording section bypassed.
Claim 4
Dependent Claim
48 words
A recording apparatus as claimed in claims 1 or 2, said switching means comprising pivotable levers arranged at intersections of said main conveying path and said bypass paths, said levers being selectively positioned so as to channel a recording sheet through only selected ones of said recording stations.
Claim 5
Dependent Claim
54 words
A recording apparatus as claimed in claims 1 or 2, wherein there are provided recording sections, and 2n-1 switching means, whereby, before each recording section and after each recording section excepting the last such recording section, a recording sheet may be selectively switched from either a main or a bypass path, to the other.
Claim 6
Dependent Claim
29 words
A recording apparatus as claimed in claims 1 or 2, wherein said switching means comprises pivotable plate means, said plates being pivotable in pairs to form shiftable guide channels.
Claim 7
Dependent Claim
34 words
A recording apparatus as claimed in claim 5, said shiftable guide channels being selectively pivotable to allow said recording sheet to pass through a selected one, selected ones or all of said recording sections.
Claim 8
Dependent Claim
29 words
A recording apparatus as claimed in claim 6, wherein at least the ink donor sheet of a bypassed recording section is maintained stationary during transport of said recording sheet.
Claim 9
Dependent Claim
115 words
A multicolor recording apparatus, comprising; a plurality of recording stations, each said station including an ink donor sheet and a recording head, a main sheet conveying path extending through each of said recording stations, a second sheet conveying path extending through none of said stations, a plurality of third sheet conveying paths which selectively allow a recording sheet to bypass any one or more of said recording sections, and means for shifting the direction of advance of said recording sheet from said main path to said second path via one of said third paths, and from said second path to said main path via another of said third paths, respectively, to bypass selected recording stations.
Claim 10
Dependent Claim
115 words
A multicolor recording apparatus, comprising; a plurality of recording stations, each said station including an ink donor sheet and a recording head, a main sheet conveying path extending through each of said recording stations, a second sheet conveying path extending through none of said stations, a plurality of third sheet conveying paths which selectively allow a recording sheet to bypass any one or more of said recording sections, and means for shifting the direction of advance of said recording sheet from said main path to said second path via one of said third paths, and from said second path to said main path via another of said third paths, respectively, to bypass selected recording stations.
Claim 11
Dependent Claim
63 words
A multicolor recording apparatus as claimed in claim 8, wherein a recording sheet is conveyed, in a recording section at least partially by said ink donor sheet, and is conveyed, when bypassing a recording section, by means other than said ink donor sheet, whereby the ink donor sheet of any bypassed recording station is not advanced during the transport of said recording sheet.
