Description

上記目的を達成するために本発明は、色インクとオーバーコートとが順に形成されたインクリボンを用いて記録用紙に印画を行うサーマルプリンタであって、サーマルヘッドにより前記記録用紙に前記インクリボンの前記色インクを転写させ、前記色インクの転写後に、前記サーマルヘッドにより前記色インクが転写された記録用紙に前記オーバーコートを転写させる印刷制御手段と、前記サーマルヘッドを、前記インクリボンおよび前記記録用紙を介してプラテンローラに圧接させる印画位置と前記プラテンローラから離間させる退避位置との間を移動させるための移動手段と、前記サーマルヘッドによる転写後の前記インクリボンを前記記録用紙から剥離するための剥離部材であって、前記サーマルヘッドと連動して移動する剥離部材と、を有し、前記移動手段は、前記色インクの転写完了時と前記オーバーコートの転写完了時とで、前記サーマルヘッドおよび前記剥離部材を前記印画位置から前記退避位置へ移動させるタイミングを異ならせることを特徴とする。 In order to achieve the above object, the present invention provides a thermal printer that prints on a recording sheet using an ink ribbon in which color ink and an overcoat are sequentially formed, and the thermal ribbon prints the ink ribbon on the recording sheet. Print control means for transferring the color ink, and after transferring the color ink, transferring the overcoat onto a recording paper on which the color ink has been transferred by the thermal head; the thermal head; the ink ribbon; and the recording peeling a moving hand stage for moving between a retracted position which is separated from the platen roller and the printing position for pressing the platen roller via the sheet, the ink ribbon after transfer by said thermal head from said recording sheet A peeling member for moving in conjunction with the thermal head; Has the moving means, in that during the transfer completion of the overcoat and the time of transfer completion of the color ink, varying the timing of moving to the retracted position the thermal head and the peeling member from said printing position It is characterized by.

Claims

A thermal printer that prints on recording paper using an ink ribbon in which color ink and overcoat are sequentially formed,
Print control means for transferring the color ink of the ink ribbon to the recording paper by a thermal head, and transferring the overcoat to the recording paper to which the color ink has been transferred by the thermal head after the transfer of the color ink;
Said thermal head, and moving the hand stage for moving between a retracted position which is separated from the platen roller and the printing position for pressing the platen roller through the ink ribbon and the recording paper,
A peeling member for peeling the ink ribbon after transfer by the thermal head from the recording paper, the peeling member moving in conjunction with the thermal head,
The moving unit is configured to change the timing of moving the thermal head and the peeling member from the printing position to the retracted position when the color ink transfer is completed and when the overcoat transfer is completed. Thermal printer.

The moving means, when the transfer of the overcoat is completed, at a timing when a predetermined amount has passed after moving the thermal head and the peeling member from the print position to the retracted position when the transfer of the color ink is completed. The thermal printer according to claim 1, wherein the thermal head and the peeling member are moved from the printing position to the retracted position.

The moving means moves the thermal head and the peeling member to the retracted position at the transfer completion timing when the color ink transfer is completed, and when the overcoat transfer is completed, a predetermined timing elapses from the transfer completion. 3. The thermal printer according to claim 2, wherein the thermal head and the peeling member are moved to the retracted position later.

Further, the image forming apparatus further includes conveying means for conveying the recording paper and the ink ribbon at the time of transferring the color ink and the overcoat by the thermal head , wherein the conveying means is configured to transfer the overcoat. After the transfer is completed, the recording paper and the ink ribbon are conveyed, and at the timing when the transfer completion position of the recording paper and the ink ribbon is conveyed to the position of the peeling member, the moving means includes the thermal head and the The thermal printer according to claim 3 , wherein the peeling member is moved to the retracted position.

When the thermal head is in the printing position, the peeling member is in a position to contact the recording paper via the ink ribbon, and when the thermal head is in the retracted position, the peeling member is in the recording position. the thermal printer according to any one of claims 1 to 4, characterized in that in a position separated from the sheet.
