[Detailed description of the invention] <Technical field of invention> The present invention relates to a transfer printing device such as a thermal type.

<Prior Art> A thermal transfer printing device known as a transfer printing device has a storage unit that stores, for example, a TV image-autumnal equinox signal, an ink sheet coated with color ink, and an ink sheet coated with color ink. It comes from the thermal transfer head, which melts it with heat and transfers it to paper.

A conventional example of such an apparatus is shown in FIG. 1. Reference numeral 11 denotes an ink sheet in which yellow (G), magenta dark, and cyan (G1. black side) ink sheet portions are connected in series; 12 is a roller that holds the ink sheet 11; 16 is a photographic paper; 15 is a roller that moves the photographic paper 16; 14 is a fixed thermal transfer head located at one position. It is.

Then, the ink sheet 11 is moved by the rollers 12' and 13.
The ink sheet 11 is sequentially wound and fed, and the photographic paper 16 is moved back and forth by a roller 15 for a number of times in addition to the number of colors of the ink sheet 11, thereby performing color transfer printing.

However, in such a conventional apparatus, a photographic paper 16 for obtaining a large number of images is wound and held around a roller 15, and an ink sheet 11 for obtaining a large number of images is also wound and held. - Because of the structure with 15.13 μm, it is necessary to install these μm 15.13 separately on the device, which is inconvenient to use, especially when you want to quickly obtain a single image. was inconvenient and inconvenient to use.

Moreover, the rollers 15 and 13 each require large diameters due to the above-mentioned construction, and there is a drawback that the apparatus for mounting these rollers 15 and 13 becomes large in size.

<Summary of the Invention> In view of the above-mentioned conventional circumstances, the present invention provides a package in which photographic paper and an ink sheet are stacked and packaged, and a transfer head contacts the ink sheet inside the package. The so-called cassette-type photographic paper and ink sheet attachment structure allows for excellent usability.
It is an object of the present invention to provide a transfer printing device that can also be miniaturized.

<Embodiment of the Invention> Hereinafter, an embodiment of the present invention will be described based on FIGS. 2 to 5.

In these figures, reference numeral 32 denotes a photographic paper to be transferred, which is formed to have a size corresponding to, for example, a photographic cabinet. Reference numeral 33 denotes an ink sheet for transfer printing arranged so as to be superimposed on the bottom surface of the photographic paper 32, and yellow, magenta, cyan, and black inks are sequentially applied to each portion of about the same length as the photographic paper 32. One end in the longitudinal direction except for the overlapping part with the photographic paper 32 is wound around a small roll rod 35. 31t'i, the photographic paper 3
2 and the ink sheet 33, and is made of a hollow, substantially rectangular paper package or the like. 31A is this package 3
This is an enlarged portion formed at one end in the longitudinal direction of the roll rod 1, and is a portion where the small roll rod 35 is positioned. 36 is the package 3
A pull-out opening for the ink sheet 33 is cut out and formed at the opposite end of the enlarged portion 31A of No. 1, and 31 is a pull-out peripheral edge of the ink sheet 33.

Reference numeral 34 designates a window portion cut out and formed on the surface of the package 31 on the ink sheet 33 side, through which a thermal transfer head (to be described later) is inserted into the ink sheet 33 side.
) 33, and is formed in the range of the image printing portion of the photographic paper 32. Here, the above-mentioned photographic paper 32, ink sheet 33, package 31. A film cassette 38 is constituted by the small roll rod 35. In this film cassette 38, when the peripheral end 31 of the ink sheet 33 is pulled out, the small roll bar 3
As the ink sheet 5 rotates, colored portions of the ink sheet 33 such as yellow (Y) and z ink (manufactured by Z Ink Co., Ltd.), which are necessary for color thermal transfer, appear one after another in the window portion 34.

Next, numeral 21 is a roller that presses the package 31 from the photographic paper 32 side, and moves in the longitudinal direction of the film cassette 38. 2
A thermal transfer head 3 presses the package 31 from the ink sheet 33 side, and the tip of this head 23 comes into contact with the ink sheet 33 through the window 34 of the package 31.

The shaft portions of these rollers 21 and head 23 are connected to each other via a fixed arm 22 made of an elastic spring material, etc., and the fixed arm 22 is also connected to the film cassette 38 compressed by the roller 21 and head 23. A solenoid 51 is provided for releasing the pressure or adjusting the pressure during transfer. That is, the solenoid 51 causes the p-ra 21 and the head 23 to
Adjust the gap. Reference numeral 24 denotes a take-up roller to which the peripheral end 37 of the ink sheet 33 is connected and for taking up and pulling out the ink sheet 33.

Next, the operation of such a device will be explained.

Now, while the head 23 moves from the right to the left of the film cassette 38, it heats the ink sheet 33 (for example, yellow V) to the line-shaped dot pattern at each position based on the color image signal. The image is transferred and printed. and ζ, actuate the solenoid 51 to release the pinching pressure of the roller 21 and head 23 on the film cassette 38, and
Return the and to the right end of the film cassette 3B, and
The ink sheet 33 is taken up by the take-up roller 24, and the next color of the ink sheet 333, for example, magenta (
This is done until the portion (to) is located on the underside of the photographic paper 32. Next, the head 23 is moved from right to left to transfer a magenta color image.

Please repeat the above steps for each color in turn.
2, a multicolor image will be printed.

According to the above configuration, the film cassette 3 contains the photographic paper 32 and ink sheet 33 for one image.
8, color printing can be performed for one image by setting the film cassette 38 in the device, and unlike conventional methods, the roller wrapped with photographic paper and the roller wrapped with the ink sheet can be printed separately in the device. There is no need to install it.

Installation can be completed with just one-touch setting of the film cassette 38, making it easy to use and convenient.

In addition, there is no need for rollers that wind and hold ink sheets and photographic paper for a large number of images as in the past, and the photographic paper 32 remains horizontal and has no curvature (because it is configured to be transferred). The roller 21 for holding down the photographic paper 32 can be made of a small diameter, thereby making it possible to downsize the apparatus.

The transfer printing apparatus using the film cassette 38 as described above is extremely effective for printing images of televisions and VTRs, color printing of electronic still cameras, and the like.

Further, in the above embodiments, multi-color transfer printing has been described, but it is of course applicable to single-color transfer printing, and in this case, no means for moving the ink sheet is required.

<Effects of the Invention> As explained above, according to the present invention, a packaging body is provided in which photographic paper and an ink sheet are stacked and packaged, and the transfer head can come into contact with the ink sheet inside this packaging body. The so-called cassette-type photographic paper and ink sheet mounting structure allows photographic paper and ink sheets to be loaded with one touch, making it easy to use and convenient, for example, when you want to quickly print out an image. At the same time,
The compact photographic paper/ink sheet mounting structure allows the device itself to be miniaturized, and is particularly effective for color transfer printing devices for TVs, VTR images, electronic still cameras, and the like.
