Abstract

PURPOSE:To make it possible to reutilize a transfer film and keep the printed content secret by providing a row of ink jet nozzles for applying thermally melting ink to a transfer film after ink transfer and an ink tank for supplying the ink to the row of ink jet nozzles. CONSTITUTION:Transfer film 3 with thermally melting ink applied and paper to which an image is transferred are allowed to come in contact with a printing head 2 consisting of thermal elements. Then the thermal elements are energized and heated in accordance with print data, and the ink on the heated part of the transfer film 3 is melted and transferred to the paper 1. After that, the ink melted by the energized thermal element 2 from an ink tank corresponding to print data is applied to the transfer film 3 from the row of ink jet nozzles 4 of the same length as the width of the transfer film 3. The transfer film 3 is an endless film stretched across paired pulleys and fed in a constant direction.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、感熱式プリンタに関し、特に転写フィルムを

Conventionally, in this type of printer, a print head consisting of a heating element is brought into contact with the transfer film, and the heating element is heated by applying electricity to melt the ink on the film, and the ink in that area is transferred to the transfer paper. The print was formed and then the transfer film was wrapped around the core.

With the conventional printers mentioned above, after printing, traces of the ink being transferred from the transfer film to the transfer paper remain, so if you look at the film after printing, you can decipher the content printed by the printer.
There were disadvantages in that it was difficult to maintain confidentiality, and the transfer film could only be used once, resulting in high costs.
