Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a flash copying method.

[Prior Art] Conventionally, as a method for copying using a flashing device, for example, a translucent stencil master is superimposed on a document and the flashing device is flashed, thereby creating an original image corresponding to the image on the document. The image of the copy original can be copied onto the transparent sheet by forming holes in a stencil master, or by overlaying a transparent sheet on a copy original on which a predetermined image has been copied using an electrostatic latent image and flashing a flashing device. There are ways to do this.

A flash copying device used in such a copying method has a structure in which a rotating case is rotatably attached to a main body, a suppression plate with a cushion material is provided on the main body of the device, and a flashing means is provided on the rotating case. It becomes. In this case, the flash means includes a discharge lamp in a light source chamber of the rotating case, one side of the light source chamber (the surface facing the pressing plate) is opened, and a transparent glass is attached to this opening. Further, the cushioning material is used to uniformly bring the stencil master and the original, or the copy original and the transparent sheet into close contact over the entire surface during copying.

When copying by the former method using such a flashlight copying device, a stencil master is attached to the outer surface of the transparent glass, the original is placed on the cushion material of the pressing plate, and then,
The rotating case is rotated to sandwich the stencil master and the original between the transparent glass and the cushioning material, and in this state, a discharge lamp is flashed to form a hole in the stencil master with an image corresponding to the original image. do. In this case, when the 1-turn case is rotated and the stencil master and the original are sandwiched between the transparent glass and the cushioning material, the entire surface of the stencil plate and the original are brought into close contact with the cushioning material evenly, resulting in copies with uniform a-shading. An image is obtained. In addition, in such a copying method, since the image itself does not become a copy, it is necessary to use a prepared original plate to perform actual transfer onto recording paper or the like. In this case, the ink is squeezed out from an ink tube filled with heat-melting ink and applied to a separate sheet, and this sheet is placed on the inner surface of the original plate and attached to a transparent glass. Place the recording paper, rotate the rotating case in the same way as described above, place the original plate and the recording paper in close contact with the transparent glass and the cushioning material, and flash the discharge lamp in this state. A copy image corresponding to the image of the original print is transferred to recording paper. A copy is thus obtained.

When copying using the latter method, as in the former method described above, attach the copy original with the image formed on the outer surface of the transparent glass, place the transparent sheet on the cushioning material of the suppression plate, and then The rotating case is rotated to sandwich the copy original and the transparent sheet between the transparent glass and the cushioning material, and in this state, the discharge lamp is flashed to copy an image corresponding to the image on the copy original onto the transparent sheet. A copy is thus obtained.

[Problem to be solved by the invention J Among the above-mentioned copying methods, the former copying method in which an original image corresponding to the original image is formed as a hole in a stencil original does not itself become a copy. Therefore, the created original must be used to perform actual transfer onto recording paper or the like, making the copying process complicated and troublesome. In addition, in the latter method of copying an image of a copy original onto a transparent sheet, it is necessary to prepare a copy original on which a predetermined image has been formed using an electrostatic latent image. Furthermore, with any of these copying methods, when copying, the stencil master or copy manuscript must be attached to the transparent glass on the rotating case side. , by placing a stencil original or a transparent sheet on the cushioning material on the device main body side, and rotating the rotating case relative to the device main body in this state, the transparent glass on the rotating case side and the transparent glass on the device main body side are connected. Since the stencil master and the original, or the copy original and the transparent sheet are sandwiched between the cushion material and the transparent sheet is copied, there is a problem that the sandwiching operation is troublesome and the workability is extremely poor. In this case, the method of copying the original image onto a transparent sheet cannot make multiple copies because the image formed each time it is copied fades, and the above-mentioned copying method can only copy onto flat objects. For example, in the former method of copying, when an image of a manuscript is formed on a stencil master and this master is used to transfer it to recording paper, etc., the original is attached to the transparent glass on the rotating case side. attached,
The recording paper is placed on the cushioning material on the side of the main body of the device, so if the recording material has an arc-shaped curved surface during transfer, the original plate will not fit the transfer surface of the recording material, so it is necessary to transfer it to a flat surface. It can only be transferred to vats, vases,
Not only can it not be copied on curved surfaces such as the arcuate or curved surfaces of pencils, but also on bound paper such as notebooks.
Clear copies cannot be made near the side edges of the binding.

The object of this invention is to be able to easily copy images freely drawn by hand, and to copy images not only on flat surfaces but also on curved surfaces such as arcuate surfaces and curved surfaces of bats, vases, pencils, etc. It is an object of the present invention to provide a flash copying device which can perform good copying even in the case of a photocopying machine.

[Means to solve the problem] The flash copying method of this invention is as follows.

a) A step of writing on recording paper such as plain paper with an ink pen containing toner to create a manuscript, where the ink of the ink pen has a melting point of 50 ° C.
It is made by melt-mixing a certain amount of paraffin wax, a small amount of synthetic resin such as polystyrene, and toner such as carbon, carbon black, graphite, etc., and diluting it with a solvent. In order to effectively carry out this invention, it is desirable that the melting point of the ink be 100° C. or lower. Further, the form of an ink pen is usually one that has the same structure as a pen using an ink-impregnated core, such as a magic pen or a felt-tip pen, or a ballpoint pen.

b) A light source chamber having a light transmitting window on at least one side, a light source lamp disposed within the light source chamber, a transparent body provided in the light transmitting window, and fixedly or removably attached to the outer surface of the transparent body. a step of preparing a flash copying device having a light-transmitting elastic sheet and a holding means for holding originals in a layered manner on the outer surface side of the elastic sheet; In the case of a transparent case, the transparent window is formed as an opening, but in the case of a transparent case, there is no need to form an opening. In addition to glass, plastic such as acrylic resin can be used. Also.

As will be understood from the examples of the present invention described below, the transparent body is not limited to a flat one, but may be curved. Also, the transparent elastic sheet may be made of foamed urethane, foamed polyester, etc. The top of the hanger looks white, but when you look through it to the light, it is fine as long as it has enough translucency to make the back side slightly visible.Of course, the higher the translucency, the better for implementing the present invention. Effective. The elastic sheet may be fixed to the outer surface of the transparent body by adhesives, screws, etc., or may be removably attached using a mounting mechanism provided on the main body of the device, and a holding means. In this method, an original plate, which will be described later, is laminated on the outer surface of the transparent body directly or with a reinforcing sheet or the like interposed therebetween.

C) a step of holding the thin sheet by the holding means on the outer surface side of the elastic sheet of the flash copying device, wherein:
As the thin sheet, a transparent resin sheet such as polypropylene is suitable, but the material is not limited to this, and a sheet based on paper such as paraffin paper may also be used.

d) With the flashlight copying device placed on the document and the other side of the thin sheet pressed against the image forming surface of the document in close contact, flash the light source lamp of the flashlight copying device; a copying step of forming a transfer image of the original image on the thin sheet;

Further, the flash copying method according to claim 2 is the flash copying method according to claim 2, which further includes the following steps.

a) When the thin sheet on which the image of the original document has been copied is installed as an original in the flash copying device, at least the portion facing the attachment area of the original is coated with a light reflective layer and the outside of the flash copying device. A process of covering the ink sheet with an ink sheet having a heat-melting ink layer disposed on its side, in which the light-reflecting layer may be formed on the ink sheet, or may be formed on a separate sheet from the ink sheet. If it is made separately from the above-mentioned engaging means, it is effective to connect it to the engaging means so that it moves together with the engaging means when inserting and removing the original. In addition, the ink sheet is
The ink sheet may be attached while the original is being held, or the ink sheet may be attached first and the original may be inserted between the first elastic sheet and the ink sheet. In this case, the ink sheet is It may be covered by attaching it to a flash copying device, but it may also be made into a roll and attached to the flash copying device in advance, and then transported by a suitable feeding mechanism to cover the attachment area of the original.

Furthermore, the ink sheet may not be attached to the flash copying device, but may simply be placed so as to cover the recording medium.

b) With the original plate, light reflective layer, and ink sheet pressed against the recording medium through the transparent body of the flash copying device, the light source lamp of the flash copying device is flashed to apply the original plate onto the recording medium. The process of forming a copy that corresponds to the image.

[Function] According to the flash copying method of the present invention, a manuscript is created by writing on a recording paper such as plain paper with an ink pen containing toner, so that the image of the manuscript can be freely created by writing. It's quick and easy to create. In addition, when copying this original, there is no need to sandwich the original and the thin sheet between the transparent body and the elastic sheet, and the thin sheet can be simply pressed onto the original. The elastic sheet allows the thin sheet to be brought into close contact with the original. Therefore, copying work is easy and clear copies can be made. Furthermore, when the copy obtained in this way is used as an original plate to be transferred to a recording medium, it is not limited to a flat recording medium such as recording paper, but also an arcuate surface such as a vase, a vase, a pencil, etc. Clear copies can be made on curved surfaces such as curved surfaces, or near the side edges of bound sheets of paper such as notebooks.

Next, a case will be described in which the handwritten image 22a of the original 22 is copied onto the thin sheet 19 using the flash copying apparatus 1 configured as described above.

In this case, first, the original 22 is created. That is,
The original 22 is created by writing on a writing recording paper 22b such as plain paper with an ink pen 22c containing toner to form a writing image 22a. The ink of this ink pen 22c is made by melting and mixing paraffin wax with a melting point of 50°C 8JI, a small amount of synthetic resin such as polystyrene, and toner such as carbon, carbon black, graphite, etc., and diluting it with a solvent. In order to carry out this process, it is desirable that the melting point of the ink is 100° C. or lower, and the form of the ink pen 22c is usually a Magic Ben,
It has the same structure as a pen or ballpoint pen that uses an ink-impregnated core called a sainben.

When creating an original plate 24 using such a document 22, first, the holder 3 is removed from the lower part of the apparatus main body 2 as shown in Fig. f5z and Fig. 3.

In this state, operate the operating lever 6.6 of the device main body 2 to push down the holding member 15.15 as shown in FIG.
A thin sheet 19 is set on the lower surface side of a transparent body 17 provided at the lower part of the light source chamber 12.

That is, when the operating button 6a of the operating lever 6 is pressed from the outside, the rotating arm 6b rotates in the direction of arrow X about the pin 6c, and the tip of the rotating arm 6b touches each contact portion 15c of the holding member 15. , 15c are pushed down against the coil spring 20. Then, the holding member 15 has guide portions 15b at both ends thereof.
, 15b are guided by the respective guides @5a, 5a of the lower case 5 and move downward, and the locking portion 15a at the lower end is pushed downward from the cushion material 17a provided at the lower part of the transparent body 17. In this state, the locking portion 1 of the holding member 15
A thin sheet 19 is inserted between the cushion material 5a and the cushion material 17a. In this case, if the thin sheet 19 is bent and difficult to insert, as shown in FIG.
The frame-shaped reinforcing sheet 31, which can be easily handled by bonding and integrating it with the thin sheet 19, has approximately the same external shape as the thin sheet 19, but has an opening in the center. In FIG. 17, the frame-shaped reinforcing sheet 31 is shown to be fixed to the side opposite to the writing image forming surface of the thin sheet 19, but of course, the frame-shaped reinforcing sheet 31 is attached to the side of the thin sheet 19 on which the transferred ink image 19a is formed. The fixing means may be fixed to the forming surface side, instead of using adhesives, by planting pins in the frame-shaped reinforcing sheet 31, making holes in the thin sheet 19, and engaging the two, or reinforcing sheet 31 It is also possible to adopt a structure in which the thin sheet 19 is inserted by providing a slit or an elastic engagement piece. In addition, the reinforcing sheet does not have to be in the shape of a frame, but can be in the form of a rectangle with approximately the same size as the thin sheet (19), and there is no need to provide an opening in the center.
In this case, the reinforcing sheet is a transparent member, and the side of the thin sheet 19 opposite to the side on which the transferred ink image 19a is formed.

In other words, it is necessary to arrange it between the cushion material 17a and the thin sheet 19. Then, when the pressure on the operating lever 6 is released, each holding member 15 is pulled up by the coil spring 20 as shown in FIG.
Press the edge of 9 directly against the edge of transparent body 17. As a result, as shown in FIG. 10, the thin sheet 19 is attached with its entire surface in close contact with the lower surface of the transparent body 17 due to the elasticity of the cushion material 17a. That is, since the size of the cushion material 17a is formed smaller than the distance between the locking parts 15a, 15a, the locking parts 15a, 15a are made of thin sheets.
The edge of the thin sheet 19 is directly pressed and held against the edge of the transparent body 17, and the thin sheet 19 is pulled in from the lower surface thereof. After the thin sheet (19) is attached in this way, as shown in FIG.
Place it on 2. In this case, the original 22 is placed close to a flat i-table 28 such as a tabletop. In this state, the device main body 2
When pressed from above, the cushion material 17a is compressed, as shown in FIG. 11, and the lower surface of the thin sheet 19 is uniformly pressed against the entire image forming surface of the original 22 and comes into close contact with it. In this case, the locking parts 15a, 15a drawn in from the lower surface of the thin sheet 19 are pressed until they come into contact with the original 22, compressing the cushioning material 17a, and uniformly bringing the thin sheet 19 into close contact with the original 22. . In this way, thin sheet 1
9 comes into close contact with the original 22, the safety switch Sc operates and closes the contact Scl. This makes it possible to copy the original 22.

Then, the power switch Sa provided on the top surface of the device main body 2 is set to the on state. Then, as shown in FIG. 8, the contact Sa is closed, charging of the flash capacitor C1 is started, and as the flash capacitor C1 is charged, the voltage VO increases, and at the same time, the input side voltage of the constant voltage detection circuit 25 increases. When Vl reaches a predetermined value, contact La of relay L is opened, charging of flash capacitor CI is stopped, and at the same time, light emitting diode IO lights up. The lighting of the light emitting diode 10 indicates that the flash preparation has been completed. In this state, when the discharge switch Sb is closed, the voltage stored in the flash capacitor CI is supplied to the trigger circuit 27, a high voltage is applied to the trigger electrode of the discharge lamp 13, and the discharge lamp 13 emits a strong flash. emits.

When the discharge lamp 13 emits a flash of light in this way, the light rays are transmitted to the transparent body 17 provided at the lower part of the light source chamber 12, as shown in FIG. The light is irradiated onto the original 22 through the cushion material 17a and the thin sheet 19. Then, since the original 22 is elastically adhered to the lower surface of the thin paper sheet 19 by the cushion material 17a, the upper layer of the written image 22a formed on the surface of the original 22 (that is, the toner contained in the ink) etc.) is transferred onto the lower surface of the thin film sheet 19 as a transfer ink image (copy image) 19a as shown in FIG. This is due to the effect that a material such as toner contained in the written image 22a absorbs the light beam and generates heat, and this heat melts the lower surface of the thin sheet 19 and the written image 22a, thereby fixing them together. As a result, the written image 22a of the original 22 is faithfully and clearly transferred to the thin sheet 19. As a result, a copy of the original 22 is obtained. Moreover, this copy can also be used as the original plate 24.

Next, the case where the thus-copied copy, that is, the transfer ink image 19a transferred using the original plate 24, is transferred to the recording medium 23 will be described.

In this case, first, the reels 21 and 21 on which the ink sheet 18 is wound are placed in each reel storage part 3b of the holder 3.
3b, and this holder 3 is attached to the lower part of the device main body 2. That is, each end of the inksee) 18 is wound around a reel 21, 21, respectively, and as shown in FIG.
The ink sheet 18 in the middle is placed below the holder 3, and the reels 21.21 on both sides are inserted through the sides of the holder 3 from above the reel storage parts 3b, 3b, and each shaft of the reel 21.21 is inserted. 21a... to the shaft support 3f...
Rotatably supported on the shaft. In this state, the holder 3 is aligned with the lower part of the device main body 2, and each hook portion 3c provided at the front and rear of the holder 3 is connected to the device main body 2 (the locking recess 1 of
1c. This allows the holder 3 to be attached to the device main body 2.
is attached to the bottom of the When the holder 3 is attached in this way, as shown in FIG. Inc.) 18 is stretched. The apparatus main body 2 with the ink sheet 18 stretched over it in this manner is placed on the recording medium 23 on the mounting table 28, as shown in FIG. From this state, push down the device main body 2 from above and hold the holding member 15.1 as shown in FIG.
Each of the locking portions 15a, 15a of 5 is pressed against the recording object 23 on the a placement table 28. Then, the cushion material 17a is compressed, so that the original 24 elastically comes into close contact with the upper surface of the ink sheet 1B. At the same time, the ink sheet 18 is placed on the recording medium 23! wear. In this case as well, the safety switch Sc operates to close the contact Set. This results in
Transfer to the recording medium 23 becomes possible.

In this state, when transferring to the recording medium 23,
As in the case of creating the original plate described above, first, the power switch Sa is set to the copying position H. As a result, charging of the flash capacitor C1 is started, and when the flash capacitor CI is completely charged, the light emitting diode 10 is turned on. In this case, the voltages v, , V2 increase as the charging voltage Vo increases, and have a relationship of V+>V2. Therefore, the constant voltage detection circuit 25
When connected to copy position ■, the operation will be delayed compared to when connected to copy position ■. In other words, when the power switch Sa is set to the original production position, the charging time to the flash capacitor C1 is longer than when it is set to the copying position H, and the flash capacitor C1 is charged to a higher voltage. For this reason, copy position 1
When the discharge switch Sb is closed at step m, the discharge lamp 13 emits a weaker flash than when the original was created.

In this way, when the discharge lamp 13 flashes, the light beam passes through the original 24 and irradiates the ink sheet 18 below it, as shown in FIG. When the light beam is irradiated onto the original plate 24 in this way.

Since the original plate 24 has a transferred ink image 19a formed by transferring a part of the written image 22a of the original 22 on the lower surface thereof, light rays do not pass through the transferred ink image 19a.
Moreover, since the transferred ink image 19a contains toner with good heat absorption, the portion of the transferred ink image 19a absorbs light and generates heat, while the other portions transmit heat and generate heat. It won't last, so 1M version 24
Since the light beams that have passed through the area other than the transferred ink image 19a are reflected by the light reflection layer 18b of the ink sheet 18, the ink sheet 18 in this area does not have heat, but the transferred ink image 19a of the original plate 24 The portion absorbs the irradiated light and has heat, and this heat is transmitted to the heat-sensitive ink layer 18c via the light reflection layer 18b and base film 18a of the ink sheet 18, and only the heat-sensitive ink layer 18c of this portion is melted, and this melted portion 18d is thermally transferred to the lower recording medium 23 as shown in FIG. As a result, the colored copy image 18d of the heat-sensitive ink layer 18c is reliably and clearly transferred to the recording medium 23 in correspondence with the transferred ink image 19a of the original plate 24. Note that when transferring again to another recording medium 23, the reel 21 exposed from the holder 3
．． 21 with a finger or the like, pull out and set a new ink sheet 18 necessary for one transfer under the original plate 24, and flash the discharge lamp 13 in the same manner as described above. By re-spelling, it can be transferred to any number of sheets, and it can also be easily transferred to a bound recording medium such as a notebook. In this case, when the transfer ink image 19a transferred to the thin sheet (thin sheet) 19 is thermally transferred to the recording paper via a normal ink sheet, the transfer ink image 19a is transferred to the ink sheet little by little, so several sheets are transferred. However, in the present invention, an ink sheet 18 having a light reflecting layer 18b made of a metal vapor deposited layer formed on the top surface of the ink sheet is used. 19 transfer ink image 19
Since a is in contact with the light reflective layer 18b, the light reflective layer 18b
It can be transferred to an extremely large number of recording media without being transferred at all.

Note that in this embodiment, the holder 3 to which the ink sheet 18 is attached can be replaced without removing it from the apparatus main body 2. That is, in the state shown in FIG. 6, when the operating lever 6.6 is operated, the holding member 15 is pushed down as in the case shown in FIG.
The locking portion 15a that presses the material onto the cushion material 17a
is separated from the original plate 24, and the ink sheet 18 is lifted up, and as shown in FIG. 7, the locking portion 15a and the ink sheet 18 are separated from the cushion material 17a by a large distance. Therefore, the original plate 2 that had been attached to the device main body 2 until then
4 can be removed and another original 24 inserted.

Further, in the above-mentioned flash copying apparatus 1, the transferred ink image 19a of the original plate 24 can also be transferred onto a curved surface such as a vase 30, as shown in FIG. That is, in this case, similarly to the case of transferring to the recording medium 23 described above, the flash copying device H1 in which the ink sheet is stretched over the underside of the original plate 24 is pressed against the outer peripheral surface of the vase 30. Then, the cushion material 17a is compressed and conforms to the arcuate surface of the vase 30, so that the ink sheet 18 adheres not only to the original 24 but also to the outer peripheral surface of the vase 30 accordingly. Therefore, when the discharge lamp 13 is flashed in this state, the light beam is irradiated onto the ink sheet 18 through the original plate 24, as in the case of transfer described above. As a result, the heat-sensitive ink layer 18c of the ink sheet 18 corresponding to the transferred ink image 19a of the original plate 24 is melted, and the melted portion 18d is transferred to the outer peripheral surface of the vase 30. The image transferred in this way is preferably coated with a transparent coating material so that it does not disappear even if the outer peripheral surface of the vase 30 is rubbed. It may be an arcuate surface, a spherical surface, a spherical surface, or a combination thereof such as a pole, a golf club head, or a curved surface such as a hexagonal pencil. With paper that has been printed, clear transfer can be made even near the bound side edges. This also applies to the creation of a master plate; images near the side edges of bound notebooks, wood, etc. can be clearly copied, and the master plate 24 can be created in good condition.

Note that this invention is not limited to the embodiments described above, and can be modified in various ways.

For example, the ink sheet 18 may be one in which a light reflection layer 18b and a heat-sensitive ink layer 18c are sequentially layered on the lower surface of the base film 18a, or only the light reflection layer 18b may be formed on a separate sheet. shows the latter embodiment. In this example, the light reflecting layer 18b is provided on the lower surface (the back surface of the side facing the original 24) of a transparent resin sheet 32 having approximately the same external shape as the original 24, and is attached by an adhesive tape 33. , its-
The original plate 24 and the transparent resin sheet 32 are bonded together at the side edges. In this case, the transparent resin sheet 32 is also used as a reinforcing sheet, and is integrated with the original 24 and attached to the apparatus main body 2 with the original 24 facing the transparent body 17 side. According to this method, the light reflecting layer 18b requires only the same interview as the original plate 24, so that the ink sheet 18 can be made inexpensive. The sheet 32 may be fixed to the locking portions 15a, 15a of the holding member 15 by contact M, etc. In this way, the light reflecting layer 18b covers all the original plates 2.
4 can be used in common, making it even cheaper.

Furthermore, the cushion material 17a is made to have the same external size as the original 24, and is overlapped with the original 24, temporarily bonded as the case may be, and inserted between the transparent body 17 and the locking parts 15a, 15a, and locked. It may also be held by the portions 15a, 15a.

In this case, the cushion material 17a serves as a reinforcing sheet when the original plate 24 is inserted. Of course, the cushion material 17a may be detachably attached using another attachment mechanism (not shown).

Further, the transparent body 17 is not limited to a flat shape, and the outer surface may be formed in advance into a concave or convex curved shape according to the shape of the recording medium. In this case, the transparent body 17 It can also be configured to be removable from the device main body 2.

As already mentioned, the ink sheet 1B has a light reflecting layer 18.
b may be separate, but in either case it is also possible to have a structure in which it is attached directly to the device main body 2 without using the holder 3. Furthermore, if a feeding mechanism for the ink sheet 18 is provided in the main body 2 of the apparatus, it is possible to create an original by simply moving the ink sheet 18 using the feeding mechanism without having to remove the ink sheet 18 from the main body 2 of the apparatus. It can be done.

Furthermore, although it is a little inefficient, the ink sheet 18 (with or without the light reflective layer 18b) can be attached to the recording medium 2 without being attached to the apparatus main body 2.
Alone on top! l! The original plate 24 attached to the main body 2 of the apparatus may be pressed onto the recording medium 23.

In addition, in the above embodiment, the flash energy of the discharge lamp 13 was set to be different when creating the original and when copying, but in actual tests, the same flash energy was sufficient to achieve the purpose. As in the example, the switching circuit can be omitted.

[Effects of the Invention] As explained in detail above, according to the flash copying method of the present invention, a manuscript is created by writing on recording paper such as plain paper with an ink pen containing toner. Images of manuscripts can be created freely and easily by handwriting. In addition, when copying this original, there is no need to sandwich the original and the thin sheet between the transparent body and the elastic sheet, and by simply pressing the PJ leaf receipt original against the transparent body, the transparent sheet is fixed to the transparent body. The elastic sheet allows the thin sheet to be brought into close contact with the original. Therefore, copying work is easy and clear copies can be made. Furthermore, the copy obtained in this manner can be used as an original plate to be transferred onto a recording medium. In this case, it is not limited to flat recording media such as recording paper, but also curved surfaces such as arcuate or curved surfaces of bats, vases, pencils, etc., or the bound side edges of bound paper such as notebooks. G-man copies can also be made near the area.
