Heat transfer system, winding device, heat transfer method, and winding method

A winding device that winds therearound an ink ribbon including a base layer, an ink layer on one surface of the base layer, and a back surface layer on the other surface of the base layer after ink in the ink layer is transferred to a transfer-receiving body in a first pattern, the winding device comprising:

• a winding part winding the ink ribbon having ink transferred therein therearound in such a manner that the back surface layer is positioned outside the ink layer;
• a heating element heating the ink ribbon having ink transferred therein from the back surface layer side near the winding part to transfer ink in the ink layer to the back surface layer inside the ink layer in a second pattern that is different from the first pattern;
• and
• a controller controlling the heating element, wherein
• the controller controls the heating element so that heat is generated at a temperature at which ink corresponding to the second pattern is transferred with the ink layer as a whole,
• the back surface layer contains phosphate ester,
• the base layer includes a primer layer that is in contact with the ink layer,
• the primer layer contains inorganic fine particles enhancing adhesiveness of the ink layer to the base layer,
• the controller controls the heat element to cause migration of the phosphate ester from a back surface layer of an inner ink ribbon to a primer layer of an outer ink ribbon,
• the migration of the phosphate ester causes the ink of the second pattern in the ink layer of the outer ink ribbon to be transferred to the back surface layer of the inner ink ribbon with the ink layer as a whole, adhesiveness of the ink of the second pattern to the base layer of the outer ink ribbon being enhanced by the inorganic fine particles, and
• an ink omission part in the second pattern is formed in the layer of the outer ink ribbon to disturb an ink omission part in the first pattern by the transfer of the ink of the second pattern.

A heat transfer method of transferring ink to a transfer-receiving body by using an ink ribbon including a base layer, an ink layer on one surface of the base layer, and a back surface layer on the other surface of the base layer, the heat transfer method comprising:

• sending the ink ribbon;
• heating the sent ink ribbon with a first heating element from the back surface layer side to transfer ink in the ink layer to the transfer-receiving body in a first pattern;
• winding the ink ribbon having ink transferred therein in such a manner that the back surface layer is positioned outside the ink layer;
• and
• heating the wound ink ribbon having ink transferred therein with a second heating element from the back surface layer side to transfer ink in the ink layer to the back surface layer inside the ink layer in a second pattern that is different from the first pattern, wherein
• transferring in the first pattern is performed by transferring ink corresponding to the first pattern by transferring a portion of the ink layer, and
• transferring in the second pattern is performed by controlling the second heating element so that heat is generated at a temperature at which ink corresponding to the second pattern is transferred with the ink layer as a whole,
• the back surface layer contains phosphate ester,
• the base layer includes a primer layer that is in contact with the ink layer,
• the primer layer contains inorganic fine particles enhancing adhesiveness of the ink layer to the base layer,
• heating with the second heating element causes migration of the phosphate ester from a back surface layer of an inner ink ribbon to a primer layer of an outer ink ribbon,
• the migration of the phosphate ester causes the ink of the second pattern in the ink layer of the outer ink ribbon to be transferred to the back surface layer of the inner ink ribbon with the ink layer as a whole, adhesiveness of the ink of the second pattern to the base layer of the outer ink ribbon being enhanced by the inorganic fine particles, and
• an ink omission part in the second pattern is formed in the layer of the outer ink ribbon to disturb an ink omission part in the first pattern by the transfer of the ink of the second pattern.
