Abstract

PURPOSE:To enable recording on not only thin sheets but bound notebooks, paper boards and three-dimensional bodies, by a method wherein a heat-fusible supercoolable substance layer provided on a light-transmitting base sheet is brought into contact with an image surface of an original, and is irradiated with flash light from the base sheet side to form a sticky area corresponding to the original image. CONSTITUTION:A bottom surface of a main body 1 is placed on an original image of an original 2, and is moved in the direction of an arrow A. A heat-sensitive sheet 4 is moved, and while it is passed through the region of a pressing means 9, it remains overlapped on the original 2 without slipping relative to the original 2. A flash light source 7 is momentarily turned ON to illuminate the original 2 from the back side 4a of the sheet 4. The transmitted light is absorbed by an image area to generate heat, and the surface of the sheet 4 in an area corresponding to the image area is melted by the heat, forming a sticky image. While the sticky image remains sticky, an arbitrary recording material is placed on a table 3, the bottom surface of the main body 1 is placed thereon, and is moved in the direction of an arrow B. The sheet 4 is moved along an end bent part 9b of the pressing means 9, and the sticky part of a supercoolable substance 4b is transferred onto the recording material, whereby a corresponding image is formed on the recording material.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a recording method and apparatus for recording an image of a manuscript, such as a manuscript written with a pencil, a newspaper, or a wooden manuscript, on any recording medium. It is something.

More specifically, the present invention is capable of recording not only an image of a manuscript written in pencil, a newspaper, or a wooden manuscript on a sheet of paper, for example, but also on a notebook or cardboard. The present invention relates to an inexpensive and simple recording method and apparatus that can freely and easily record even three-dimensional objects such as wooden boxes, shirts, and clothes.

[Prior Art and Problems to be Solved by the Invention] Conventionally, this type of copying method and apparatus has been used to copy books onto bound notebooks, cardboard, and three-dimensional objects such as wooden boxes, shirts, and clothes. It has not been possible to freely and easily copy images from different manuscripts. Moreover, the mechanism was complicated.

For example, in Japanese Patent Application Laid-open No. 126632/1983, light reflected from a document is received by a charge transfer element as an image sensor, and an array-shaped thermal head is made to generate heat according to this image signal.
A copying machine that colors and records on thermal paper, which is recording paper, has been disclosed. Further, as a prior art, a copying machine has been disclosed which transfers thermal transfer ink on a thermal transfer ink sheet imagewise onto a sheet of paper to record in response to heat generated by an array of thermal heads.

These are all copying machines that record on sheet-like recording paper, and cannot record on recording bodies other than thin sheets such as paper, such as three-dimensional objects such as notebooks and wooden boxes. Furthermore, these require an array-shaped thermal head as a heating element and a charge transfer element array as an image sensor, making them expensive and requiring lenses. For this reason, it was not possible to create an inexpensive and truly simple copying machine.

[Purpose of the invention]

The present invention solves the above-mentioned conventional problems and at the same time.

(1) You can freely and easily record on bound notebooks, cardboard, and even three-dimensional objects such as wooden boxes, shirts, and clothes.

(2) Another purpose is to provide an inexpensive and simple recording method and recording device that can separate the process of reading a manuscript and the process of recording on a recording medium in terms of time. That is.

Of course, this has been possible in the past. It goes without saying that it is also possible to record on sheet-like recording materials such as paper.
Further, according to the wood recording method, it is also possible to simultaneously perform the process of reading the document and the process of recording on the recording medium to be recorded.

[Means to solve the problem]

The present invention for solving the above-mentioned problems provides a heat-sensitive sheet having a heat-melting supercooled material layer on a light-transmissive base sheet, so that the heat-melting supercooled material layer side of the heat-sensitive sheet has an image of the original document. A flash light is irradiated from the base sheet side of the thermosensitive sheet, and the light transmitted through the thermosensitive sheet is absorbed and generated heat in the document image area, so that the supercooled material layer is exposed to the document image area. After forming an image-like adhesive area corresponding to the image, peeling the heat-sensitive sheet from the document, and then contacting the adhesive area of the heat-sensitive sheet against a recording medium while the adhesive area remains sticky. , a recording method characterized in that by peeling the heat-sensitive sheet from the recording body, an image-like adhesive area of the heat-sensitive sheet is transferred to the recording body to record an image on the recording body.

Still another aspect of the present invention is an apparatus for recording an image on a recording medium using a heat-sensitive sheet having a heat-melting supercooled substance as a light-transmitting base sheet, the apparatus comprising: irradiating light from the back side of the heat-sensitive sheet; a flash light source for bringing the heat-sensitive sheet into contact with the document from the back side thereof; This is a recording apparatus characterized by having a heat-sensitive sheet feeding means that moves in a direction opposite to the moving direction.

[Effect]

According to the present invention, good image recording can be performed not only on a sheet-like recording medium but also on a three-dimensional recording medium.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1(a) shows an embodiment in which the process of reading an original and the process of copying onto a recording medium such as paper or a wooden box are delayed in time. Also, Figure 1 (
b) is a cross-sectional view of the heat-sensitive sheet 4 in the thickness direction.

Note that although FIGS. 1(a) and 2 shown below are illustrated with a gap between the original 2 and the heat-sensitive sheet 4 for ease of understanding, they do not come into contact with each other during the recording process. be.

In the figure, l is the main body, and 2 is, for example, a document placed on the top of the desk 3. Further, 4 is a heat-sensitive sheet having a heat-melting supercooled material layer 4b having a thickness of 3 to 200 #Lm on a light-transmitting substrate sheet 4a made of polyester terephthalate, polyamideimide, or the like having a thickness of 3 to 300 pm. Further, 5 is a roller around which the heat-sensitive sheet 4 is wound, and 6 is a take-up reroller for winding up the heat-sensitive sheet 4. 7 is heat sensitive sheet 4
A flash light source, such as a xenon lamp, is used to irradiate light from the back side (substrate sheet 4a side) of the document 2, and reference numeral 8 is a reflecting mirror for effectively irradiating light from the flash light source 7 onto the original 2. Further, reference numeral 9 denotes a pressing means for transmitting the light from the flash light source 7 and for bringing the thermosensitive sheet 4 into close contact with the original 2 from the back side thereof. Note that this pressing means 9 has light transmittance and has approximately the same width as the exposure area of the flash light source 7. Reference numerals 10 and 11 indicate the manuscript 2 or the thermosensitive sheet for moving the thermosensitive sheet 4 in the direction opposite to the moving direction of the main body l by an amount substantially the same as the amount by which the main body l is moved relative to the bell body. It is a means of sending. The heat-sensitive sheet feeding means 10 and 11 have rollers 12Φ13 and 14 and rollers 15, 16 and 17, which have the same diameter and rotate in conjunction with each other, and have a thickness of 50 mm with little mechanical elongation.
・Position control sheet 18/19 from gm to about 300gm
The rollers 20 and 21 are configured to have position control sheet supply rollers 20 and 21 that always have the function of winding up (for example, a polyester sheet, a metal sheet, etc.) using the force of a spring (not shown). Here, the position control sheets 18 and 19 have approximately the same width as the exposure area of the flash light source 7. Further, 221123 is an opening provided on the lower surface of the main body 1 for passing the heat-sensitive sheet 4, and the heat-sensitive sheet 4 that has passed through this opening 23
passes through the lower surface 9a of the presser means 9, passes through the opening 22, and is wound up on the winding roller 6. Further, 24 and 25 are openings through which the position control sheets 18 and 19 pass, respectively.

As mentioned above, the heat-sensitive sheet 4 has a thickness of 3 to 300 g.
A heat-melting supercooled substance is applied in a layer of 3 to 200 gm, preferably 3 to 100 gm, onto a light-transparent base sheet of polyester terephthalate or polyamideimide, preferably 50 to 200 gm. (Fig. 1(a)).

Here, the supercooled substance refers to ink that has supercooling characteristics.
I'm tasting it. In addition, ink with supercooling characteristics refers to a melted or softened state or sticky state that can be transferred to a recording medium even at a temperature below the ink's original melting point or softening point when it is heated to melt or soften and then cooled. An ink that retains water for a certain period of time, and refers to a heat-melting supercooled substance. Of course, an ink having supercooling characteristics may be prepared by dispersing a coloring agent containing dyes and pigments alone or in a mixture of two or more in a thermofusible supercooled substance to such an extent that at least part of the wavelength of visible light is transmitted. In addition, as the supercooling substance, known plasticizers such as N-cyclohexyl-P-1 luenesulfonamide, N-ethyl-p-)luenesulfonamide, dicyclohexyl phthalate, or benzotriazole, acetalinide, etc. , or these derivatives may be used alone or in combination of two or more, or these may be used in thermoplastic resins such as polyamide resins, polyacrylic resins, polyvinyl acetate resins, or copolymers of these, It is also possible to mix a conventional heat-melting binder made of various natural or synthetic waxes, etc. and apply it onto a light-transmitting base sheet as an ink having supercooling properties, and then use the solidified product as the heat-sensitive sheet 4. .

Next, in the above configuration, the original 2 is read and the thermal sheet 4 is read.
The process of forming an image-like adhesive image corresponding to the image of the original document 2 on the thermofusible supercooled material layer 4b on the surface of the original document 2 will be explained.

As shown in FIG. 1, first, the lower surface of the main body 1, that is, the lower surface 9a of the holding means 9 is placed on the original image of the original 2. As shown in FIG. Next, align the position control sheet 18 over the document image area of the document 2 desired to be copied, and place the main body l.Next, the operator places the main body l
, and move the main body l in the direction of arrow A while applying force to press the main body l against the desk 3.

At this time, the operator grasps and presses the end 18a of the position control sheet 18, and then the wide position control sheet 18
Therefore, the main body 1 can move straightly with respect to the original M2.

As the main body 1 moves, the roller 14, which slides on the sheets 18 that are sequentially pulled out from the roller 20, rotates in conjunction with the movement. At the same time, this roller 14 and the roller 12 which is in pressure contact with the position control sheet 18 between them rotate in conjunction with each other, and in conjunction with the roller 12, the roller 13 also rotates. Therefore, the heat-sensitive sheet 4 is taken up and moved by the take-up roller 6 by the amount that the main body 1 moves relative to the original 2. Note that the roller 6 and roller 12 or roller 13 are, for example, a gear train (
(not shown) and interlock with each other. therefore,
At least while the heat-sensitive sheet 4 passes through the region of the holding means 9, the heat-sensitive sheet 4 and the document 2 remain overlapped and the relative speed is zero and there is no deviation. A flash light source 7 is turned on momentarily for each movement unit of the heat-sensitive sheet 4 whose length is slightly smaller than the range width, and the document 2 is illuminated from the back surface 4a of the heat-sensitive sheet 4. In other words, the light source 7
Turn on the flash. This is done, for example, by detecting the rotation of the roller 12 and turning on the light source 7 every time the roller 12 rotates. Therefore, the light from the light source 7 that has passed through the heat-sensitive sheet 4 is absorbed by the image area (for example, a black character area) of the document 2 and generates heat. As a result, the area of the supercooled material layer 4b on the surface of the heat-sensitive sheet 4 corresponding to the image area receives heat and melts, and the pressing means 9 corresponding to the image area of the document 2 is placed on the supercooled material layer 4b. An end bend image-like adhesive image (WI image) is formed.

The adhesive images formed one after another in this way move along the bent end portion 9b of the pressing means 9 and peel off from the original M42.
The adhesive image is sequentially wound onto the roller 6, but in order to allow the adhesive image to be wound onto the roller 6 without being disturbed, a layer 'A' is placed on the surface of the roller 12 and the back of the light-transmissive base sheet 4a of the heat-sensitive sheet 4. It is preferable to provide the # layer, and the distance over which the main body l can be moved for image formation is within the length of the one position control sheet 18, and after the image formation is completed, the sheet 18 can be moved by opening the end 18a. The roller 20 is moved by the spring force mentioned above.
is wound up.

Next, a process of copying the adhesive image formed on the heat-sensitive sheet 4 through the above process onto a recording medium to be copied will be explained. This process will also be explained using FIG.

Through the above process, while the adhesive image formed on the heat-sensitive sheet 4 remains sticky, first place an arbitrary recording material such as a wooden box, notebook, or shirt on the desk 3 instead of the original 2; On top of this, the lower surface 9 of the main body l, that is, the lower surface 9 of the pressing means 9.
0 Next, align the position control sheet 19 on top of this recording medium and place the main body 1. This time, contrary to the above, the main body 1 is moved in the direction of arrow B by holding down the end 19 of the position control seat 19.

At this time, the operator places the upper part of the main body 1 on the recording body (the recording body is not shown, but for example It can be thought of as a sheet-like object similar to document 2), and is moved in the direction of arrow B while pressing strongly. Then,
As in the previous process, the roller 17 rotates as the position control sheet 19 is sequentially pulled out, and as the roller 17 rotates, the rollers 15 and 16 rotate in conjunction with each other, and at least the presser The heat-sensitive sheet 4, which has an image-like adhesive image (latent image) on its surface in the region of the means 9, moves without shifting at a relative speed of zero while overlapping the recording medium, and is sequentially wound around the roller 5. Here, the heat-sensitive sheet 4 has an end bent portion 9 of the pressing means 9.
b, and when it enters the opening 23, it separates from the recording medium. At this time, the adhesive part of the supercooled substance 4b, which is the image-like adhesive image formed in the above step and still has adhesiveness, is transferred to the recording medium, and an image corresponding to the original image of the original 2 is recorded. formed in the body l.

Note that in this step, the lighting circuit of the flash light source is turned off by a switch (not shown).

Next, another embodiment will be explained using FIG. 2.

FIG. 2 shows an embodiment in which the process of copying onto a sheet-like recording medium is performed simultaneously with the process of reading the original.

In the figures, the same parts as those in FIG. 1 are shown in the same figures as in FIG. 1. 26 is a sheet-like recording material (for example, recording paper - OHP sheet, etc.), 27 is an opening for inserting the sheet-like recording material 26, and 28 is a copied sheet-like recording material 26 and a used thermal sheet 4. This is an opening for discharging water.

First, the operator manually inserts the sheet-like recording material 26 through the opening 27, aligns the position control sheet 18 with the document 2, and fixes it.Next, while holding the end 18a of the sheet 18, move the main body 1 in the direction of the arrow 13. 2 along the original 2. Similar to FIG. 1, the roller 14 rotates by sliding on the position control sheet 18 that is pulled out, and as the roller 14 rotates, the rollers 12 and 13 that are in pressure contact with each other rotate in conjunction with the rotation of the roller 14. Therefore, the heat-sensitive sheet 4 having an image-like adhesive image (latent image) on the surface formed in the area of the pressing means 9 irradiated by the light source 7 at the same timing as in the above embodiment, and the recording body inserted through the opening 27 26 are brought together with strong force at the nip portion where the rollers 12 and 13 are pressed against each other.

After that, the heat-sensitive sheet 4 is peeled off from the recording body 26 at the opening 28, and the adhesive part of the supercooled substance, which is an image-like adhesive image, is transferred to the recording body 26, and an image corresponding to the original image of the original 2 is created. It is copied onto the recording medium 26.

In this way, according to this embodiment, the process of reading the document and the process of transferring it to the recording medium can be performed in continuous, ie, almost simultaneous, steps.

Note that the copied images on the recording medium obtained in the embodiments of FIGS. 1 and 2 are not fixed naturally, but may be more firmly fixed by means of heating means, solvent vapor adding means, or the like.

Further, by this means, the adhesive image portion transferred to the recording medium or the color of the paper in the adhesive image portion may be changed in color. For this purpose, for example, a material in which a known thermal coloring agent is mixed into a cooling substance may be used as the supercooled ink.

Alternatively, the adhesive image area transferred to the recording medium may be dyed by attaching a sublimation dye vaporized by heating to change the color of the adhesive image area. In this case, the recording medium such as cellulose or paper may be dyed. It has weak affinity and is not stained.

On the other hand, -OH is added to the above-mentioned hot-melting supercooled substance.

A supercooled substance layer is created using a material mixed with sublimable dyes having a structure of polar groups such as -NH2, -NO2, -302, and hydrophobic polymers such as polyester, acrylic, and acetate, which have affinity and chemical adsorption power. When formed, the adhesive image can be easily dyed with the sublimation dye. Furthermore, a material that changes color by chemically reacting with the sublimable dye may be mixed into the supercooled material layer. Representative examples of the sublimable dye include the following.

Co1or Index DisperseYel
low7 (for example, BAS F's Haranil Yellow 5RX) Color Index Disperseed6
0 (For example, Sumitomo Chemical's Imicalon RED-FBL) Color Index Dispersel 1ue
80 It goes without saying that these means may be provided within the apparatus shown in FIGS. 1 and 2.

For example, in the embodiment shown in FIG. 2, after an image-like adhesive image is transferred to the recording body 26 by passing between the rollers 12 and 13, the recording body 26 having the transferred adhesive image on its surface is transferred to the opening 28. These coloring means may be provided in the path leading to exit from the container.

Furthermore, a filter may be inserted between the flash light R7 and the front side of the pressing means 9 to cut light of a wavelength that is absorbed by the heat-sensitive sheet.

Note that the heat-sensitive sheet described in each of the above embodiments can be replaced with a new sheet at once or replaced with a new sheet after being used several times, depending on the thickness of the supercooled substance attached or the type of recorded original image. It is okay to replace it or as long as it is appropriate.

〔Effect of the invention〕

As explained above, according to the invention, it is possible not only to record a manuscript written with a pencil, or an image of a manuscript such as a newspaper or a wooden manuscript on a sheet-like recording medium, but also on a notebook or on a notebook. It is possible to provide an inexpensive and simple recording method and device that can freely and easily record on cardboard as well as on three-dimensional objects such as wooden boxes, shirts, and clothes. .

Furthermore, in the present invention, by using a flash light source such as a xenon lamp that is turned on only momentarily as a light source, there is a significant difference in temperature rise between the image area and the non-image area of the document, so that a clear adhesive image can be It can be formed on a sheet, thereby making it possible to obtain clear recorded images.
