Abstract

PURPOSE:To enable the use of a material having no flexibility, by constituting the titled printer so that a transfer material feed path is made linear at a thermal transfer recording part. CONSTITUTION:Thermal transfer guide plates 8, 9 for linearily feeding a thermal transfer material 6 forwardly and rearwardly around a thermal transfer recording part and guide rolls 7 for feeding the thermal transfer material 6 forwardly and rearwardly while pressing the same to the guide plates are provided and a mechanism for feeding the thermal transfer material 6 forwardly and rearwardly by a platen roll 2 and the guide rolls 7 is provided. In order to prevent the thermal transfer material 6 from shifting left and right, both sides of the guide plate 8 are formed into left and right L-shaped shift preventing guides 8a and the support shaft of the aforementioned guide roll 7 is received in the vertical grooves 8b formed to said preventing guides 8a in an up-and-down movable manner. The guide plate 9 is similarly constituted. Because the thermal transfer material is linearily fed, the use of cardboard such as a postcard or a name card, plastic such as a card and a metal etc. having no flexibility as the thermal transfer material is enabled.

。Detailed Description of the Invention (a) Purpose of the Invention [Field of Industrial Application] The present invention is directed to the transfer of a pigment or dye transfer material from a heat-sensitive transfer film to a transfer material by a thermal recording means such as a thermal head. The present invention relates to a thermal printer that performs recording by printing.

［従来の技術］従来から複数の発熱体ドツトからなるサーマルヘッドを
用いたカラー感熱転写記録装置の被転写材料の搬送方法
としては２方式が提案されており。[Prior Art] Two methods have been proposed as a method for conveying a transfer material in a color thermal transfer recording device using a thermal head consisting of a plurality of heating element dots.

簡単に図に基いて説明すると、まず１方式としては第４

位置までフィルム搬送方向とは逆方向に搬送され、色重
ね数だけ以上の動作が繰り返される。To explain briefly based on the diagram, the first method is the fourth method.
As shown in the figure, the thermal transfer film 5 is rolled around the pressing part of the platen roll 2 which presses the thermal transfer film and the thermal transfer material 6 against the thermal head heating part 1 which becomes the thermal transfer recording part. The thermal transfer material 6 is conveyed in one direction to the take-up roll 3, and is transferred to the thermal transfer film 3 by the guide roll 7 and platen roll 2 during thermal transfer recording.
When the recording of the first color is completed, the film is conveyed in the opposite direction to the film conveyance direction to the recording head position, and the operation is repeated for the number of overlapping colors.

命的な欠点を有している。This method can use both cut paper and roll paper as the thermal transfer material, but since the thermal transfer material has a U-shaped conveyance path along the platen roll 2 and thermal transfer recording is performed, the thermal transfer material can be used as a thermal transfer material. Cardboard used for postcards, business cards, etc., and plastics used for plastic cards, etc., have a fatal drawback of being unusable because they do not have flexibility.

料を使用できないという致命的な欠点を有している。Next, as a second method, as shown in FIG. A method has been proposed in which a thermal transfer image is obtained by rotating the paper in the same direction as the direction in which the sheet moves from the take-up roll 4 to the take-up roll 3 of the paper discharge section by the number of overlapping colors. Compared to the first method, this method has the advantage that it is less likely to cause misregistration (misregistration) when overlapping colors because the transfer material 6 rotates integrally with the platen roll. As in the first method, since the material to be transferred is wound around the platen roll, the material to be transferred 6 must be visible, and the material to be transferred may be cardboard such as postcards, business cards, or plastic cards. It has a fatal drawback in that it cannot use non-flexible materials such as plastics used in other products.
