Abstract

PURPOSE:To obtain a transfer image of high quality irrespective of the type of a recording sheet by providing a means for thermally transferring an inverted ink negative image on a film and a means for transferring a positive image through the previous means. CONSTITUTION:An ink ribbon 2 supplied from an ink ribbon supply reel 1 passes between a thermal head 3 and the first platen 4 together with a film base 2A which loses ink 2B to form a positive image 5. The ribbon 2 on which the image 5 is formed passes between a transfer head 6 and the second platen 10 to transfer the image to a record sheet 9. The ribbon 2 loses all ink 2b, then passes again between the head 3 and the first platen 4 together with the ribbon 2 supplied from the reel 1 to form a negative image 7 corresponding to the inverted recorded information to be wound on an ink ribbon winding reel 8.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a thermal transfer recording device that heats a thermal transfer recording medium based on recorded information and transfers the melted portion of ink onto recording paper.

(Prior art) Conventionally, a positive image is formed by once transferring an ink negative image of recorded information reversed on a thermal recording medium to a film with a good surface condition and material, and then the positive image is transferred to recording paper. For example, a heat-transferable recording device that can obtain a high-quality transferred image regardless of the surface condition or material of the recording paper is disclosed in JP-A-57-150587; Apparatuses capable of transferring negative images and positive images of information are disclosed in Japanese Patent Laid-Open No. 57-64595 and Japanese Patent Laid-open No. 57-120455.

However, the former method requires a drum for transferring the ink of the negative image, an ink reheating device, and a remaining ink recovery mechanism as means for removing the ink negative image corresponding to the inverted recorded information. Although this method has advantages such as protection against leakage of confidential information through used thermal transfer recording media, it has drawbacks such as making the device complicated, large-sized, and expensive. In addition, in the latter method, when a positive image and an inverted negative image of recorded information are transferred to a first recording paper and a second recording paper, respectively, a high-quality transferred image can be obtained depending on the type of the first recording paper. There is a drawback that it cannot be done.

(Object of the Invention) The present invention has been made in view of the above-mentioned drawbacks, and provides a thermal transfer type recording device that can obtain high-quality transferred images regardless of the type of recording paper, has a simple structure, and is easily miniaturized. The purpose is to provide equipment.

(Example) Hereinafter, the invention will be described in detail based on an example. FIGS. 1 to 5 show an example of the present invention and a partially enlarged view of the example. will be explained using the same figure numbers.

FIG. 1 shows a schematic configuration diagram of a thermal transfer recording apparatus according to a first embodiment of the present invention, which includes an ink ribbon supply reel 1, a thermal head 3, a first platen 4, a transfer head 6, a second It includes an ink transfer section consisting of a platen 10 and the like.

The ink ribbon 2, which is a thermal recording medium supplied from the ink ribbon supply reel 1, is attached to a film base 2A as shown in FIG.
The ink ribbon 2 is composed of an ink layer 2B formed by coating one side of the ribbon with a heat-melting or heat-sublimating ink that is solid at room temperature. 1st platen 4
A positive image 5 corresponding to the recorded information is created by passing through the
is formed. The ink ribbon 2 on which the positive image 5 has been formed passes between the transfer head 6 and the second platen 10 together with the recording paper 9, whereby the positive image 5 is transferred onto the recording paper 9. The ink ribbon 2 loses all the ink 2B and becomes only the film base 2-A, and its direction is changed by the roll 9 and the ink ribbon 2 is again fed between the thermal head 3 and the first platen 4 together with the ink ribbon 2 supplied from the in-line supply reel 1. The diagram shows a schematic configuration diagram of the recording apparatus, in which the ink ribbon supply reel 1, the thermal head 3, the transfer head 6, the ink ribbon take-up reel 8, the first platen 4 , a second platen 10, a film supply reel 12, a film take-up reel 13, and the like.

The ink ribbon 2 supplied from the ink ribbon supply reel 1 passes between the thermal head 3 and the first platen 4 together with the film 14 supplied from the film supply reel 12, thereby forming a positive image 5 corresponding to recorded information. The ink ribbon then passes between the transfer head 6 and the second platen 10 together with the recording paper 9, thereby transferring the positive image 5 onto the recording paper 9 and winding it up on the ink ribbon take-up reel 8. on the other hand,
A negative image 11 corresponding to the inverted recorded information is formed on the film 14, and the film is wound onto the film take-up reel 13.

FIG. 4 shows a schematic configuration diagram of a thermal transfer recording apparatus according to a third embodiment of the present invention, which includes an ink ribbon supply reel 15, a thermal head 3, a transfer head 6, a platen 16, and a film take-up reel. As shown in FIG. 5, the number 18 number 21 includes a film base 2IC, an ink layer 21B formed by coating one side of the film base 21C with heat-melting or heat-sublimating ink that is solid at room temperature, and the ink layer 2.
Film base 21 of film ribbon 21 on side 1B
A positive image 19 of recorded information is formed on C, and a reversed negative image 20 of recorded information is formed on film 21A.
The ink ribbon C passes between the thermal transfer head 6 and the platen 16 together with the recording paper 9 to transfer the positive image 19 onto the recording paper 9, and then is wound onto the ink ribbon take-up reel 17. On the other hand, the film 21A on which the negative image 20 is formed is wound onto the film take-up reel 18.

(Effects of the Invention) According to the present invention, it is possible to obtain a high-quality transferred image regardless of the type of recording paper, and the drum, ink reheating device, and remaining ink recovery mechanism in the above-mentioned conventional examples are unnecessary. Therefore, it is possible to provide a thermal transfer recording device that has a simple structure, requires no maintenance and inspection, and is small and inexpensive.
