Double-side printing system
First Claim
1. A double-side printing system comprising:
- a printer section having a first printing assembly for printing first images with a first ink ribbon on a record medium, and a second printing assembly for printing second images on the record medium with a second ink ribbon; and
a turning section for turning over the record medium sent out from said printer section and sending back the record medium to said printer section wherein said turning section comprises a rotary body rotatable on a turning axis, said rotary body including roller units with feed rollers being in contact in pairs on said feed passage;
a feed means including at least one axial pulley disposed on said turning axis for transmitting rotational motion produced by said feed means to at least one of said feed rollers to move the record medium held between said feed rollers;
means for turning said rotary body; and
a rotation switch means for selectively transmitting the rotational motion of said feed means to said at least one feed roller.

Abstract
A double-side printing system has a printer section for printing images on the obverse side of a card, and a turning section for turning over the card sent out from the printer section and sending back the inverted card to the printer section so as to print various images on the reverse side of the card. The printer section performs printing of smooth color gradation images such as photographs with dye-sublimation color inks, and binary gradation images such as bar code patterns and letters with monochromatic thermal wax-transfer ink. The card having its obverse side printed with images is sent to the turning section and turned over 180° so as to print other images on the reverse side of the card.

9. A double-side printing system comprising:
-
a printer section having a feed passage along which a record medium is fed, a first printing assembly for printing multiple gradation images with dye-sublimation color inks on one side of the record medium, and a second printing assembly for printing binary gradation images on said one side of said record medium with monochromatic thermal wax-transfer ink, said first and second printing assemblies being placed on one side of said feed passage; and a turning section for turning over the record medium sent out from said printer section and sending back the record medium to said printer section wherein said turning section comprises a rotary body rotatable on a turning axis, said rotary body including roller units with feed rollers being in contact in pairs on said feed passage;
a feed means including at least one axial pulley disposed on said turning axis for transmitting rotational motion Produced by said feed means to at least one of said feed rollers to move the record medium held between said feed rollers;
means for turning said rotary body; and
a rotation switch means for selectively transmitting the rotational motion of said feed means to said at least one feed roller. - View Dependent Claims (10, 11, 12, 13, 14)

15. A double side printing system comprising:
-
a printer section having a feed passage along which a record medium is fed, a printing assembly including an ink ribbon coated with dye-sublimation color inks and/or a transparent protective layer and a thermal print head for thermally printing multiple gradation images with dye-sublimation color inks on the record medium and thermally transferring said transparent protective layer onto said record medium; and a turning section for turning over the record medium sent out from said printer section and sending back the record medium to said printer section, said turning section including a rotary body having roller units with feed rollers being in contact in pairs on said feed passage;
a feed means including at least one axial pulley disposed on said turning axis for transmitting rotational motion produced by said feed means to at least one of said feed rollers to move the record medium held between said feed rollers;
means for turning said rotary body; and
a rotation switch means for selectively transmitting the rotational motion of said feed means to said at least one feed roller.
