Abstract

PURPOSE:To manufacture easily an original plate which is excellent in shelf life and fidelity in human handwriting by a method wherein a transfer sheet having a light reflection layer and a heat sensitive ink layer is laminated on the original plate, and the heat sensitive layer of a part corresponding an ink image of the original plate is transferred to paper to be recorded by flashing a light source lamp. CONSTITUTION:Sheet paper 15a having a transparent property is prepared, and ink images 15b, 15c are formed on both up and down faces. The ink image 15b on the front face side is also formed in handwriting with a writing tool. The ink image 15c on the bank surface side is formed by thermal transfer with a thermal transfer apparatus or the like. When a discharge lamp 9 emits an intensive flash, a thermal transfer sheet 14 under an original plate 15 is irradiated thereby through the original plate 15. When the original plate 15 is irradiated thus by light, the ink image 15b, 15c parts absorb the light to generate heat. Since the light is reflected by a light reflection layer 14b of the thermal transfer sheet 14 for parts other than said part, the sheet 14 generates no heat. This heat is transmitted to a heat sensitive ink layer 14c via the light reflection layer 14b and a paste film 14a of the thermal transfer sheet 14 to fuse the heat sensitive ink layer 14c of this part, and this fused part 14d is thermally transferred to paper to be recorded 18 on the down side.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a thermal transfer method and apparatus.

[Prior Art] Conventionally, heat-sensitive type and stencil type methods are known as thermal transfer methods. The heat-sensitive type is a method in which a heat-sensitive sheet is brought into close contact with the ink image forming surface of the document and heat energy such as light is applied to cause the coloring layer of the heat-sensitive sheet to develop colors corresponding to the ink image on the document. In addition, with the stencil type, a stencil printing master is placed on the original, and a light beam is irradiated from above to transfer the image of the original onto the stencil printing master, creating an original. Apply the
This is a method in which images of the original plate are sequentially transferred onto recording paper such as postcards.

[Problem to be solved by the invention 81 However, the former heat-sensitive type method uses a heat-sensitive coloring layer, so if it is stored for a long time, external light will accumulate and cause the entire coloring layer to develop color. However, it has the disadvantage of poor storage stability. In addition, with this method, if there are thick and thin lines in the ink image of the original, the heat energy absorbed by the thick lines is greater, so the coloring layer corresponding to the thick lines is Furthermore, since this method uses thermal energy to color the coloring layer of the heat-sensitive sheet, it is difficult to create an original plate by hand.

Furthermore, in the latter stencil type method, holes are made in the stencil printing original plate by irradiation with light, and ink soaks into the recording paper through these holes, so the original plate coated with ink cannot be used for long periods of time. If left unused, the ink will ooze out, resulting in poor preservation and poor fidelity. Further, since this method involves creating a master plate by perforating a stencil printing master plate by irradiating it with light, it is difficult to create the master plate by hand. If the original plate is created by hand using a pen or the like, it is necessary to write off the rows, etc. of the original plate for stencil printing with a uniform force, and it may not be possible to write them off neatly, making it difficult to create the desired original plate. is difficult.

An object of the present invention is to provide a thermal transfer method and an apparatus therefor, which have excellent storage stability and fidelity and can easily create an original plate by hand.

[Means for Solving the Problems] The thermal transfer method of the present invention involves preparing a transparent thin paper, forming an ink image on the surface of the thin paper to create an original plate, and using the original plate on which the ink image has been formed. The ink image forming surface is fixedly held in a flash device having a transparent member and a light source lamp so as to face the transparent member, and a transfer sheet having a light reflective layer and a heat-sensitive ink layer is attached to the original plate fixedly held in the flash device. A recording paper is placed in close contact with the heat-sensitive ink layer, and the light source lamp is flashed while the heat-sensitive ink layer is pressed against the recording paper by the transparent member of the flash device. This is a method of transferring a portion of the heat-sensitive ink layer corresponding to the ink image of the original onto the recording paper. In this case, the ink image formed on the thin paper may be printed by electrostatic copying or thermal printer. In addition to being formed by one or more of these methods, such as handwriting with a writing instrument, it is also formed by thermally transferring an image of a document. Moreover, the ink image is formed on one or both sides of the tissue paper.

Further, the thermal transfer device of the present invention includes a case body having a light source chamber and a power source chamber, a light source lamp disposed in the light source chamber, a light reflecting plate disposed on the back side of the light source lamp, and the light reflecting plate. a transparent member provided facing the transparent member; a power supply device that flashes the light source lamp housed in the power supply room; a light reflective layer and a heat-sensitive ink layer; the light reflective layer is provided facing the transparent member; An ink image is formed on the surface of a transparent thin paper, and the transparent member and the transfer sheet are attached with the ink image forming surface facing the transparent member. The original plate is held in between.

[Function] According to the thermal transfer method of the present invention, since a translucent sheet of paper is used as the original plate sheet, there is no element that changes over time, such as penetration of coloring agent or ink, so that the preservability is improved. Good quality and excellent fidelity. Moreover, in addition to electrostatic copying and printing with a thermal printer, thin paper allows easy formation of ink images by hand, making it possible to easily create an original. Further, according to the thermal transfer method of the present invention, when a light beam is irradiated from the thin paper side, the light beam is transmitted through a portion of the original plate other than the ink image on which an ink image is formed on the surface of the thin paper, and the light beam that has passed through this portion is is reflected by the light-reflecting layer of the transfer sheet, but the ink image absorbs the light and generates heat, and this heat is transmitted to the heat-sensitive ink layer via the light-reflecting layer of the transfer sheet, causing the ink image and The corresponding portion of the heat-sensitive ink layer is melted, and this melted portion is transferred to the recording paper. In this case, since the heat-sensitive ink layer of the transfer sheet and the recording paper are in pressure contact, the transfer of the fused portion to the recording paper becomes more reliable, and clear transfer can be performed.

Further, according to the thermal transfer device of the present invention, the original plate on which the ink image is formed on the surface of the transparent 1 #j sheet is fixedly held on the transparent member by the holding member, and the transparent member transfers the original plate through the original plate. Since the configuration is such that the light source lamp is flashed while the heat-sensitive ink layer of the transfer sheet and the recording paper are in pressure contact,
The thermal transfer method described above can be carried out efficiently.

Next, using the thermal transfer device 1 configured as described above,
The case where the original plate 15 is created and transferred onto the recording paper 18 will be explained.

When creating the original plate 15, first, a transparent thin paper 15a is prepared, and ink images 15b and 15c are formed on both the upper and lower surfaces of the thin paper 15a as shown in FIG.

The ink image 15b on the upper surface side is formed not only by electrostatic copying, printing by a thermal printer, etc., but also by handwriting with a writing instrument. Further, the ink image 15c on the lower surface side is thermally transferred from an ink image of a normal electronic manuscript (not shown) using the above-mentioned thermal transfer device 11 or the like. That is,
This thermal transfer is performed on a thin paper 13 on a transparent glass 13 provided at the lower part of the light source chamber 8 of the apparatus main body 2, similar to the original plate 15 described later.
5a, the device body 2 is placed on a document on which an ink image has been formed, and the thin paper 15a is brought into pressure contact with the ink image formation surface of the document.In this state, the discharge lamp 9 in the light source chamber 8 will be described later. By flashing the light, at least the upper layer of the ink image of the document is transferred onto the thin paper 15a. As a result, an ink image 15c on the lower surface side is obtained. p like this
Training vapor or Japanese paper can be used as the J-leaf paper. However, paraffin paper is recommended as the paper that can most effectively carry out the present invention. JIS
According to Z 1510, paraffin paper is made by uniformly coating or impregnating glassine paper or kraft paper with a coating agent mainly containing paraffin.

Here, paraffin refers to methane series hydrocarbons or paraffin wax. However, the above definition
It should be interpreted as broadly as is consistent with the embodiments and objectives of the invention. That is, the object of the present invention is achieved by using paper as the base and uniformly coating or impregnating at least one surface with a coating agent having properties equivalent to paraffin. Since ink images produced by writing instruments have a low heat absorption rate, if the purpose is to thermally transfer handwritten ink images, it is desirable that the thin paper be extremely thin, and the
It is recommended that it be about 30 ILm. Such ultra-thin tissue paper also has sufficient light transmission. Further, the ink images 15b and 15c may be formed on either the upper or lower surfaces of the thin paper 15a, but in order not to stain the ink @ 15c that has been thermally transferred in advance when forming the ink image 15b by handwriting etc. In addition, it is desirable to form the ink image 15b on the upper surface by handwriting or the like so that it does not overlap the ink image 15c that has been thermally transferred in advance.In such a case, paraffin paper is coated with paraffin on both sides. The one coated with is suitable. It should be noted that the ink images 15b and 15c are preferably those made by mixing carbon powder with good heat absorption rate into resin, and since the thin paper 15a is thin and difficult to attach to the main body 2 of the apparatus, the ink images shown in FIG. It is preferable to attach the frame-shaped support 19 shown in FIG. An elastic sheet (not shown) may be provided under the recording paper 18.

Original plate 1 on which ink images 15b and 15c are formed in this way
5 into the main body 2 of the device. In this case, first remove the holder 3 from the lower part of the device main body 2 as shown in FIG. The holding member 11.11 is pushed down and the original plate 15 is set on the lower surface of the transparent glass 13 provided at the lower part of the light source chamber 8. That is, when the operating button 4a of the operating lever 4 is pushed from the outside, the rotating arm 4b rotates in the direction of the arrow X around the bin 4C, as shown in FIG.
The tip of this rotating arm 4b is connected to each contact portion 1 of the holding member 11.
1c and 11c are pushed down against the coil spring 16. Then, the holding member 11 has guide portions flb and l at both ends thereof.
lb is guided by the guides yt2h, 2h of the lower case 2b and moves downward, and the locking part 11a at the lower end is pushed out downward from the transparent glass 13 provided at the lower part of the light source chamber 8. In this state, the original 15 is supported by the frame-shaped support 19 and inserted between the locking portion 11a of the holding member 11 and the transparent glass 13. in this case.

If necessary, the original 15 may be glued to the frame-shaped support 19, and when the control lever 4 is released, each holding member 1 is moved by the coil spring 16 as shown in FIG.
1 was raised respectively.

A locking portion 11a at the lower end holds the edge of the original 15 in a recess 13a provided at the edge of the transparent glass 13.

Thereby, the original plate 15 is mounted in close contact with the lower surface of the transparent glass 13.

After the original plate 15 is mounted in this way.

The reel 17° 17 on which the thermal transfer sheet 14 is wound is stored in each reel storage part 3b, 3b of the holder 3, and the holder 3 is mounted on the lower part of the main body 2. That is, each end of the thermal transfer sheet 14 is wound around a reel 17.17, and as shown in FIG. 2, the intermediate thermal transfer sheet 14 is placed below the holder 3, and the reels 17.
17 respectively through the sides of the holder 3 into the reel storage section 3.
b, 3b from above, and each shaft portion 17a of the reel 17, 17 is rotatably supported by the shaft support 3f. In this state, the holder 3 is aligned with the lower part of the device main body 2, and each hook portion 3c, 3c provided at the front and rear of the holder 3 is
and the locking recess 2j on the main body z side. Thereby, the holder 3 is attached to the lower part of the device main body 2. When the holder is attached in this way, the transparent glass 1 of the light source chamber 8
Only the original 15 held on the bottom surface of 3 is in the opening 3 of the holder 3.
It protrudes downward from a, and the thermal transfer sheet 14 is stretched over the lower surface thereof. The apparatus main body 2 with the thermal transfer sheet 14 stretched over it is placed on the recording paper 18, and the thermal transfer sheet 14 is brought into pressure contact with the recording paper 18 via the original plate 15 by the transparent glass 13. This makes it possible to transfer the image onto the recording paper 18. In this case, thermal transfer sheet) 14
The image transferred to the original plate 15 is transferred to recording paper 1B such as plain paper.
As shown in FIG. 7, the total thickness is about 3 to 50 ILm, and the upper surface of a transparent or opaque base film 14a such as polyester is coated with nickel (nickel).
A light reflecting layer 14b made of a metal vapor deposited layer such as aluminum (AI), copper (Cu), etc. is formed, and a heat-sensitive ink layer 14c made of heat-melting color ink or the like is formed on the lower surface of the base film 14a. The structure is as follows.

When transferring to the recording paper 1B, the charging switch Sa provided on the top surface of the apparatus main body 2 is set to the on state. Then, charging starts, and when charging is completed, the light emitting diode 7 lights up. In this state, when the discharge switch Sb is operated, the discharge lamp 9 emits a strong flash of light. When the discharge lamp 9 emits a flash in this way,
As shown in FIG. 7, the light beam is irradiated onto the original 21 through the transparent glass 13 provided at the bottom of the light source chamber 8 and the original plate 15 below it. Then, as shown in FIG. 7, the light beam passes through the original plate 15 and onto the thermal transfer sheet 1 below.
4. When the light beam is irradiated onto the original plate 15 in this way, the original plate 15 forms the ink images 15b and 15 as described above.
c is provided, these ink images 15b and 15c
The light rays do not pass through the part, and this ink image 15b,
Since the ink image 15c contains black carbon, etc., which has good heat absorption, the ink images 15b and 15c absorb the light rays and have heat, while the other parts have heat because the light rays pass through them. Therefore, the light beams that have passed through the parts of the original plate 15 other than the ink images 15b and 15c are reflected by the light reflection layer 14b of the thermal transfer sheet 14, so the thermal transfer sheet 14 in these parts does not have heat. , original version 15
The parts of the ink images 15b and 15c have heat due to the irradiated light beam, so this heat is transmitted to the heat-sensitive ink layer 14C via the light-reflecting layer 14b and the base film 14a of the thermal transfer sheet 14, and the heat-sensitive ink in these parts is heated. The layer 14c is melted, and the melted portion 14d is thermally transferred to the lower recording paper 18 as shown in FIG. As a result, images corresponding to the ink images 15b and 15c on the original plate 15 are reliably and clearly transferred to the recording paper 18.

When transferring again to another recording paper 18, rotate either one of the reels 17 (17) exposed from the holder 3 with your finger or the like to remove the thermal transfer sheet (1) necessary for one transfer.
4 and set it under the original plate 15, and flash the discharge lamp 9 in the same manner as described above.By repeating this, it is possible to transfer as many sheets as you like, and it is also possible to transfer notes etc. It can also be easily transferred to recording paper. In this case, when the transfer ink image 15b transferred to the original plate 15 is thermally transferred to the recording paper via a normal ink sheet, the transfer ink image 15b is transferred to the ink sheet little by little, so the transfer ink image 15b is transferred to the recording paper on several sheets. However, in this invention, a light reflecting layer 1 made of a metal evaporation layer is added to the top surface of the ink sheet.
4b is used, and the original plate 1
Since the ink image 15b on the lower surface side of No. 5 is in contact with the light-reflecting layer 14b, it is not transferred to the light-reflecting layer 14b at all, and can be transferred onto an extremely large number of recording papers 18...

On the other hand, when replacing the original plate 15, the operating lever 4.4
When the operating buttons 4a, 4a are pressed from the outside, the locks 11a, lla of the holding member 11.11 are pushed down below the transparent glass 13, as shown in FIG.
Since the thermal transfer sheet 14 is separated below the transparent glass 13 by a and 11a, there is no need to remove the holder 3 from the apparatus main body 2, and the original plate 15 can be replaced simply and easily.

Note that the frame-shaped support 19 may be provided on either the upper surface or the lower surface of the original 15, and does not necessarily have to be frame-shaped, but may be planar. In particular, the ink image 15b formed on the original 15 If the ink image 15b comes into direct contact with the transparent glass 13, the ink image 15b will adhere to the transparent glass 13, so in such a case, it is recommended to place a transparent planar support sheet between the original 15 and the transparent glass 13. Reflective layer 14b
The thermal ink layer 14c and the thermal ink layer 14c may be formed on different base films and laminated.

[Effects of the Invention J] As explained in detail above, according to the thermal transfer method of the present invention, since a translucent paper was used as the original plate sheet, there were no problems such as penetration of the coloring agent and ink. Since there are no elements that change, it has good storage stability and excellent fidelity. Moreover, F! In addition to electrostatic copying, printing with a thermal printer, etc., ink images can be easily formed on J-sheets by hand, and original plates can be easily created. Further, according to the thermal transfer method of the present invention, when a light beam is irradiated from the thin paper side, the light beam is transmitted through a portion of the original plate other than the ink image on which an ink image is formed on the surface of the thin paper, and the light beam that has passed through this portion is is reflected by the light-reflecting layer of the transfer sheet, but the ink image absorbs the light and generates heat, and this heat is transmitted to the heat-sensitive ink layer via the light-reflecting layer of the transfer sheet, causing the ink image and The corresponding portion of the heat-sensitive ink layer is melted, and this melted portion is transferred to the recording paper. In this case, since the heat-sensitive ink layer of the transfer sheet and the recording paper are in pressure contact, the transfer of the fused portion to the recording paper becomes more reliable, and clear transfer can be performed.

Further, according to the thermal transfer device of the present invention, the original plate on which the ink image is formed on the surface of the translucent FM paper is fixedly held on the transparent member by the holding member, and the transparent member transfers the ink image through the original plate. Since there is no need to flash the light source lamp while the heat-sensitive ink layer of the sheet and the recording paper are in pressure contact, the above-described thermal transfer method can be carried out efficiently.
