About.

  Conventionally, in order to save the trouble of adhering stamp ink to the stamp surface each time a stamp is printed, a stamp in which sponge rubber is used as a stamp and impregnated with ink in advance is known.

  For example, a stamp in which a printing plate (printing surface material) made of a porous sheet is attached to a rootstock is fixed on a plate making apparatus, a thermal head is pressed against the surface of the porous sheet and moved, and the heating element of the thermal head is moved. There has been proposed a manufacturing apparatus that selectively heats and forms a printing surface comprising a melt-solidified portion through which ink does not pass and a non-melted portion through which ink passes through the printing plate. (For example, refer to Patent Document 1.)

Japanese Patent Laid-Open No. 10-100144

  By the way, the technique described in Patent Document 1 uses a carriage as a drive mechanism for the thermal head. However, the mechanism for driving the thermal head by the carriage has a large structure and has recently responded to the demand for downsizing of the apparatus in the market. Can not.

  Further, as apparent from FIG. 4 of Patent Document 1, an end face head is used as the thermal head.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Example 1]
FIG. 1 is a block diagram of a system configuration of a thermal printer for plate making (hereinafter, simply referred to as a printer) that detects the size of a marking material of a medium holder according to the first embodiment of the present invention and performs appropriate plate making.

  As shown in FIG. 1, the printer 1 includes a central control circuit 2. The central control circuit 2 includes a sensor 3, a thermal head 4, a power supply circuit 5, a motor driver 6, a display screen control circuit 7, and a memory control circuit 8. , A UI (User Interface) control circuit 9, a USB control circuit 10, a Bluetooth (registered trademark) module / wireless LAN module 11.

  A stepping motor 12 is connected to the motor driver 6, a display device 13 is connected to the display screen control circuit 7, and a PC (personal computer) 14 is connected to the USB control circuit 10.

  In the case of this example, the sensor 3 is composed of a reflective optical sensor. In addition, the display device 13, the display screen control circuit 7, the UI control circuit 9, the USB communication control circuit 11, the Bluetooth (registered trademark) module / wireless LAN module 11, and the like are not necessarily required.

  In FIG. 1, a central control circuit 2 controls the entire system. In this figure, most of the circuits are connected only to the central control circuit 2, but it is of course possible for the circuits to perform data communication through the bus. The central control circuit 2 is a circuit including a CPU (central processing unit), and when the CPU reads and executes a computer program as necessary, a later-described XX means (for example, a conveyance amount detection means, a dimension setting) Means, dimension determination means, position detection means, etc.).

The memory control circuit 8 includes devices such as a ROM (read only memory) and a RAM (Random Access Memory) and controls them. The display device 13 indicates a display device such as an LCD (Liquid Crystal Display), for example, and the display image control circuit 7 controls data transfer to the display device 13 and lighting / extinguishing of the backlight.
Various correspondence tables (correspondence tables) to be described later are stored in a ROM or the like, and are written and referred to in a RAM and used as needed. This stamp plate making apparatus is installed with driver software installed on the personal computer side and operates in cooperation with a USB connection or the like. Therefore, it is possible to place the correspondence table on the personal computer side without placing it on the stamp plate making apparatus side.

  For example, in the case of a model in which connection to the PC 14 or wireless connection is indispensable, the user performs an operation on the GUI (Graphical User Interface) such as the PC 14 or a mobile phone terminal (not illustrated), and thus the display screen control is performed on the hardware side. The circuit 7 and the display device 13 are not essential.

  The UI control circuit 9 controls menu screen display and the like based on information input from an input device such as a keyboard, mouse, remote controller, button, or touch panel. The power supply circuit 5 includes a power supply IC (integrated circuit) or the like, and generates and supplies necessary power to each circuit.

  Porous ethylene vinyl acetate copolymer (hereinafter referred to as EVA) in contact with the head by receiving the data and print signal output from the thermal head 4 and the central control circuit 2 and controlling the energized dots by the driver IC inside the head. Printing (plate making or printing, the same shall apply hereinafter) is performed on the stamp material such as.

  In the configuration example of this system, other circuits receive only data and signals from the central control circuit 2, and power necessary for printing is obtained from the power supply circuit 5. Incidentally, in the apparatus of this example, the thermal head 4 has an effective print width of 48 mm with a resolution of 200 dots / 25.4 mm.

  The motor driver 6 is a driving circuit that drives the stepping motor 12, receives a signal output from the central control circuit 2, and supplies a driving pulse signal and electric power to the stepping motor 12. Note that only the excitation signal is received from the central control circuit 2, and the actual drive power is obtained from the power supply circuit 5.

  The central control circuit 2 accurately counts how many steps the stepping motor 12 has rotated by counting the number of pulses of the signal output to the motor driver 6, that is, how many mm the print medium (medium holder described later in this example) has been conveyed. Can be grasped.

  The printer 1 in this example employs 1-2 phase excitation drive, and the gear ratio is configured to be 16 steps per line (0.125 mm). That is, conveyance of 0.0078 mm is performed in one step.

  FIG. 2 is an external perspective view showing the printer 1 together with the medium holder. FIG. 2 shows a state in which the medium holder 16 is inserted into the print medium insertion port (plate making insertion portion) 15 of the printer 1 and the leading end 16 a is exposed to the outside from the discharge port 17. A stamping material 18 is held at 16.

  3A is a plan view of FIG. 2A, and FIG. 3B is a sectional side view of FIG. 3A and 3B show a state immediately after the medium holder 16 is inserted into the print medium insertion port 15 of the printer 1. The tip 16a of the medium holder 16 is inserted to the vicinity of the position where the sensor 3 is disposed. A thermal head 4 and a platen roller 19 are disposed in front of the conveyance path.

  4A is a plan view of the medium holder 16 that holds the stamp material 18, FIG. 4B is a cross-sectional view taken along the line AA ′, and FIG. 4C is the back surface of FIG. 4A. FIG.

  As shown in FIGS. 4A and 4B, the medium holder 16 holds the stamp material 18 in a fixed position. An arrow a shown in FIG. 4A indicates the conveyance direction of the medium holder 16 in the printer 1.

  The medium holder 16 is configured by bonding two thick paperboards 21 (upper thick paperboard 21a and lower thick paperboard 21b) made of coated balls. A cutout 22 is formed in accordance with the position detected by the sensor 3 on one side (right in FIG. 4A) of the medium holder 16 (see also FIG. 3A).

  The printer 1 detects the notch 22 along the detection scanning line 23 indicated by a one-dot chain line by using the sensor 3, as will be described in detail later, and the vertical and horizontal dimensions of the stamp material 18 and printing (plate making). The same applies to the following).

  A positioning hole 24 for fixing the position of the stamp material 18 is provided in the upper thick paperboard 21a. The marking member 18 is fitted into the positioning hole 24 at its lower portion and fixed in position.

  Here, the upper surface of the stamp material 18 is configured to slightly protrude from the upper surface of the upper thick paperboard 21a. In this example, the thickness of the stamp material 18 is 1.5 mm, but the thickness of the upper thick paperboard 21a is designed to be 0.79 mm.

  This is because the thermal head 4 enables stable plate-making control by performing heat treatment (printing and plate-making) while crushing the EVA of the stamp material 18 slightly.

  The lower cardboard 21b has the same outer shape as the upper cardboard 21a, and the entire inner surface is flat. The lower cardboard 21b and the upper cardboard 21a are integrated by bonding, and the lower cardboard 21b is in contact with the lower surface of the stamp material 18 and holds the stamp material 18 from below.

  As shown in FIG. 4C, the lower thick paperboard 22b is provided with perforations 25 along the positioning holes 24 shown in FIG. 4A. The upper part of the perforation 25 forms a perforation 25a that extends right and left to both end portions of the lower cardboard 22b.

  The marking member 18 held by the medium holder 16 is composed of a porous sponge body that can be impregnated with ink. As the material of the sponge body, for example, ethylene vinyl acetate copolymer is used.

  Then, as shown in FIG. 4B, the surface of the upper cardboard 21a and the surface and side surfaces of the stamp material 18 exposed to the outside from the positioning holes 24 of the upper cardboard 21a are covered with a film 26.

  The film 26 is made of PET (Polyethylene Terephthalate) or polyimide as a base material, and has heat resistance, heat conductivity, and surface smoothness. Regarding heat resistance, a material having heat resistance at a temperature higher than the melting point of the stamp material 18 is used.

  FIG. 5 is an enlarged view of a portion surrounded by a broken-line circle b in FIG. As shown in FIG. 5, the upper cardboard 21a and the lower cardboard 21b are bonded by a double-sided adhesive sheet 27b.

  Further, the film 26 is adhered to the surface of the peripheral portion of the medium holder 16, that is, the peripheral surface of the upper cardboard 21 a positioning hole 24 into which the stamping material 18 is fitted, by the double-sided adhesive sheet 27 a, The surface of the part is covered.

  The film 26 further covers the side surface 18b and the surface 18a of the stamp member 18 exposed to the upper part from the positioning hole 24, but is not bonded. Therefore, after the plate making of the stamping material 18 is completed, the lower thick paperboard 21b is folded back along the perforations 25a shown in FIG. 4C, and the portion surrounded by the perforations 25 and 25a is the upper thick paperboard 21a. When it is separated from the marking member 18, the marking member 18 can be easily taken out from the medium holder 16.

  Here, the principle of making the stamp surface of the stamp by heating the surface of the porous EVA constituting the stamp material 18 with a thermal head will be briefly described. First, since porous EVA (hereinafter, porous EVA is simply written as EVA) has innumerable bubbles, liquid such as ink can be impregnated inside like a sponge.

  Further, since EVA has thermoplastic properties, for example, when heated with heat of 70 to 120 degrees, a portion where heat is applied is softened, and once softened, the portion is cured when cooled. The hardened portion is filled with bubbles and made non-porous, and the portion cannot pass liquid such as ink.

  Therefore, by utilizing this characteristic, when an arbitrary portion of the EVA surface is heated by the thermal head for about 1 to 5 milliseconds, the arbitrary portion of the EVA surface is made non-porous, and the ink in that portion is made. Can be prohibited.

  That is, in the imprint of the stamp to be created, an ink transmitting portion corresponding to the imprint can be formed by saying that “a portion that transmits ink is not heated and a portion that does not transmit ink is heated”.

  When the operation of the heating process by the thermal head is replaced with the operation of the printing process of the conventional thermal printer, the white and black of the print data representing the imprint are reversed. Further, since it is an imprint on the seal surface, the print data is mirror surface data of the seal image data created by the user.

  Using this principle, the surface of the EVA is reversed in black and white according to the desired imprinting and selectively heated, thereby prohibiting the passage of the ink in the heated portion and forming the ink impregnated in the non-heated portion. It can be extruded according to the seal.

  By the way, in the heat treatment of the EVA surface, the ink oozes out from the portion that is not heated. Therefore, the portions other than the seal image intended by the user must be heated so that ink does not come out from the portions.

  However, it is inevitable that the position of the center of the EVA is slightly deviated from the design value with respect to the center line of the thermal head due to assembly errors in the mass production process. In this state, ink leaks from a location (for example, an end portion of EVA) that is not intended by the user.

  As a specific example, for example, it is assumed that the imprint data created by the user is 30 mm × 30 mm. On the other hand, it is assumed that the portion where the thermal data is heat-treated by the thermal head is also 30 mm × 30 mm.

  Here, when the position of the EVA is shifted by 1 mm in the scanning direction due to an assembly error, not only the center of the printing surface is shifted by 1 mm but also 1 mm at the end is not heated, so that ink leaks from the end. A malfunction occurs.

  In order to avoid this problem, in the heating process by the thermal printer of this example, black solid print data is added to set a heating margin area for prohibiting ink leakage outside the imprint data edited by the user. The print data is used for imprint printing that is actually executed.

  For this reason, for example, when the size of the marking surface is displayed for 30 mm × 30 mm and the medium holder is provided to the user, the actual size of the marking surface material is (30 + L) × (30 + L) mm. L is, for example, 1 mm to 2 mm.

  Of course, what the user creates / edits is imprint data after imprinting on the object to be imprinted. Therefore, data obtained by mirror-inversion of desired imprint data created by the user is actually made on EVA.

  To summarize the above, the imprint data created and edited by the user is subjected to “black and white reversal” and “mirror reversal” processing, and the black solid data for the heating margin is added to the surrounding area to produce the final thermal data. Print data to be input to the head.

  By using this print data to heat the EVA surface with a thermal head, it is possible to easily make a plate having a user's own impression on the stamp material. In order to take out the stamping plate made by making the stamping material from the medium holder 16, it is only necessary to separate the lower cardboard 21b from the upper cardboard 21a along the perforations 25 and 25a as described above.

  By the way, EVA is a member having a thickness of 1.5 mm, and has high elasticity and friction coefficient. For this reason, even if EVA is inserted into a thermal printer as it is and transported, the frictional force between the thermal head and EVA is large, and stable straight transport cannot be performed.

  In other words, EVA has a large frictional force and is soft like rubber. Even if a guide for obtaining straight running stability is attached on the thermal printer side, EVA can bend even a little during transportation. Will bend, and as a result, skew will occur immediately.

  The difficulty in transporting the EVA described above is a phenomenon that occurs even in a non-heated state where the thermal head is not generating heat. However, when the thermal head generates heat, the thermal head is about 200 in a few milliseconds after the start of heat generation. Since the temperature rises to a degree close to that, the surface softens at the moment when the EVA surface is heated, and the thermal head is buried in the softened portion, and the EVA cannot be transported at all.

  In the case of a method using an end face head or a method in which a carriage is incorporated to move and drive the head, the above problem does not occur. However, this method causes an increase in the size of the mechanism and a significant increase in the cost of the member used. As mentioned above, there are disadvantages.

  In the present invention, the above-described printer 1 shown in FIGS. 1 to 3 (a) and 3 (b) using a normal thermal head is used without causing an increase in the size of the mechanism and a significant increase in cost. The medium holder 16 shown in FIGS. 2 to 5 is used in order to perform plate making using EVA having difficulty in transportability as a printing plate.

  First, the four sides of the stamp material 18 held in the positioning holes 24 of the medium holder 16 are cut by a thermal cutting machine. Thereby, the ink impregnated inside does not ooze from the four sides of the stamp material 18.

  Further, the stamping material 18 is fixed in position by the positioning hole 24 of the upper cardboard 21a, held from the lower surface by the lower cardboard 21b, and covered with the film 26 on the upper surface, so that it is held by the medium holder 16. It cannot be transformed no matter how external force is applied.

  Therefore, the medium holder 16 is conveyed as it is conveyed. If the medium holder 16 is transported straight, the stamp material 18 is also transported straight. Further, the film 26 has heat resistance at a temperature higher than the melting point of the stamp material 18, that is, EVA.

  Therefore, even if the surface of the stamp material 18 is melted by the heat generated by the thermal head 4, the film 26 is not melted. That is, the covering property as a film is not lost. Further, the frictional force between the film 26 and the thermal head 4 is extremely low.

  For this reason, the thermal head 4 is not buried in the stamping material 18 which has been melted and softened due to the covering property of the film 26, and along the surface of the film 26 due to low friction with the film 26. Can easily continue exothermic printing (plate making). In this way, the plate making to the stamp material 18 is completed.

  FIG. 6 is a diagram illustrating a state in which the stamp plate after completion of the plate making and taken out from the medium holder 16 is attached to the rootstock of the stamp stand and completed as a seal stamp. As shown in FIG. 6, the stamping material 18 is attached to the lower surface of a rootstock 30 composed of a spherical handle 28 and a pressing portion 29 with a double-sided adhesive sheet 31, with the stamping face facing down as a plate-making stamping plate. ing.

  If the printing surface is immersed in ink for a certain time, the ink is impregnated into the printing plate. After the user wipes off excess ink stains on the surface of the stamping surface, the user holds the handle 28 with his / her finger and presses the pressing portion 29 against the object to be stamped, so that the impregnated ink is pushed out from the stamping surface and the imprint is imprinted.

  4A is a square and the medium holder 16 is a rectangle. However, the shape and dimensions of each are not limited to those shown in FIG. The shape and dimensions of the medium holder 16 are arbitrary as long as they are within the width that can be inserted into the printer 1 shown in FIGS. 2 and 3A, 3B, and within the dimensions that can be held by the medium holder 16. For example, the shape and dimensions of the stamp face material 18 are arbitrary.

  FIGS. 7A to 7F are diagrams showing the front and back of only three examples of various shapes and dimensions of the medium holder and the stamp material as a reference. FIGS. 7A and 7B show an example in which a vertically long rectangular printing medium is held on a vertically long rectangular medium holder.

  FIGS. 7C and 7D show an example in which a vertically long rectangular printing face material is held on a substantially square medium holder, and FIGS. 7E and 7F show a square printing face material on a square medium holder. The example which hold | maintained is shown. As described above, the shape and dimensions of the medium holder and the stamp material are arbitrary.

  The configuration of the medium holder for the control unit of the printer 1 to detect the size of the stamping material having an arbitrary size and shape and the print start position will be described again with reference to FIG. As shown in FIG. 4A, the medium holder 16 can show three values of α, β, and γ by the notch 22.

  α is the length from the leading end in the insertion direction along the detection scanning line 23 indicated by the alternate long and short dash line of the medium holder 16 to the starting end of the notch 22, for example, “(1 / α) × a” (a is a constant), Alternatively, the length of the marking material 18 can be expressed by a correspondence table of α and the vertical length of the marking material.

  β is the length from the start end to the end of the notch 22, for example, “β × b” (b is a constant), or a correspondence table between β and the width of the marking material, and represents the width of the marking material 18. it can. γ is the length from the end of the notch 22 to the tip of the marking member 18 and corresponds to the length from the sensor 3 to the thermal head 4 and can indicate the print start timing.

  The printer 1 uses the sensor 3 to detect the leading end portion on the insertion direction detection scanning line of the medium holder 16 and the start and end of the notch portion 22 along the detection scanning line 23 indicated by the alternate long and short dash line. The length is measured by the number of steps of the stepping motor 12, and on the one hand, the vertical and horizontal dimensions of the stamp material 18 are calculated or obtained from the correspondence table, and on the other hand, the print start timing is obtained.

  FIG. 8 is a flowchart for explaining the operation of the plate making process performed by the central control circuit 2 (hereinafter simply referred to as a control unit) of the printer 1. This process is started when the printer 1 is powered on and imprint data is transmitted from the PC 14.

First, the control unit waits for the medium holder 16 to be inserted from the print medium insertion port 15 (step S1). And it is discriminate | determined whether the front-end | tip on the detection scanning line of the medium holder 16 by the sensor 3 was detected (step S2), and if not detected (determination of step S2 is No), it will wait until it detects.

  If the tip of the medium holder 16 on the detection scanning line is detected by the sensor 3 (Yes in step S2), a pulse signal is supplied to the stepping motor 12 via the motor driver 6 to rotate it, and the stepping motor 12 Measurement of the number of steps of the pulse signal supplied to is started (step S3). Subsequently, the control unit rotates the stepping motor 12 by one step and conveys the medium holder 16 by the amount corresponding to the one step rotation (step S4).

  Next, the control unit determines whether or not the notch start end of the notch 22 has reached the position of the sensor 3 (step S5). If not reached (No in step S5), the process returns to step S4, and the processes in steps S4 and S5 are repeated.

  Eventually, if the sensor 3 detects that the notch start end (notch start portion) of the notch portion 22 has reached the position of the sensor 3 (Yes in step S5), the control unit scans the medium holder 16. A conveyance distance from the front end of the line to the notch start end of the notch 22 is calculated by calculation based on the number of steps measured by the stepping motor 12 (step S6). This calculation result is stored in the storage area of a predetermined memory device via the memory control circuit 8 as the first transport distance α.

  Subsequently, the control unit restarts measurement of the number of steps of the stepping motor 12 from step 0 (step S7). Subsequently, the control unit rotates the stepping motor 12 by one step and conveys the medium holder 16 by the amount corresponding to the one-step rotation (step S8).

  Next, the control unit determines whether or not the notch end of the notch 22 has reached the position of the sensor 3 (step S9). If not reached (No in step S9), the process returns to step S8, and the processes in steps S8 and S9 are repeated.

  Eventually, if the sensor 3 detects that the notch end of the notch 22 has reached the position of the sensor 3 (Yes in step S9), the control unit will transfer the transport distance from the start end to the end of the notch 22 ( The length of the notch 22 is calculated by calculation based on the number of steps measured by the stepping motor 12 (step S10). This calculation result is stored in the storage area of a predetermined memory device via the memory control circuit 8 as the second transport distance β.

Here, the control unit reads the first transport distance α stored in the memory device. Then, based on, for example, “(1 / α) × a” (a is a constant) set in advance or a correspondence table of α and the vertical length of the stamping material, the length of the stamping material 18 is determined.

  Further, the control unit reads the second transport distance β stored in the memory device. Then, based on, for example, “β × b” (b is a constant) set in advance or a correspondence table between β and the width of the marking material, the width of the marking material 18 is determined.

  Then, the control unit determines whether or not the length and width obtained by removing the heating margin region from the determined length and width of the stamping material 18 match the length and width of the imprint data transmitted from the PC 14 (step S1). If they match (Yes in step S11), printing is started (step S12). When printing is completed, the plate making process is terminated.

  The thermal head 4 at the time when the sensor 3 detects that the notch end of the notch 22 has reached the position of the sensor 3 is located immediately before the front end of the stamping material 18. Plate making starts when the end of the notch is detected. In this plate making, print data in which a predetermined heating margin area is added to the front, back, left and right of the seal impression data transmitted from the PC 14 is used.

  If the length and width obtained by removing the heating margin area from the determined length and width of the stamp material 18 do not match the length and width of the imprint data transmitted from the PC 14 in step S11, The determination in step S11 is No), the printing process is stopped without starting, and the discrepancy error is displayed on the display device 13, or the PC 14 is notified via the USB control circuit 10, and the plate making process is immediately terminated. To do.

  As described above, according to the embodiment of the present invention, it is held in the medium holder 16 only by changing the position and length of the notch 22 provided on one side of the medium holder 16 for each dimension of the marking material 18 to be held. Thus, the size of the stamping material 18 can be detected correctly. Thereby, the plate-making mistake by the mistake of the stamping material size by a user can be prevented.

  Further, the initial investment for that purpose is only the cutting blade type when the medium holder 16 is produced, and can be realized at a very low cost. For example, the cutting blade mold is at most about 50,000 to 100,000 yen per type, and is very inexpensive as compared with a mold for a molded product.

  Hereinafter, an example is shown about the shape of the notch part of a medium holder.

[Example 2 wedge-shaped notch]
FIG. 9 is a diagram illustrating the shape of the medium holder according to the second embodiment (wedge shape). FIG. 9A shows the surface side, that is, the side on which the stamping material is placed. FIG. 9B shows an AA ′ cross section. FIG. 9C shows the back side. As shown in FIG. 9, the medium holder is the same as that shown in FIG. 4 except for the shape of the notch.
As shown in FIG. 9, the shape of the notch is a triangle (wedge shape) that bites inward. In the case of this shape, similarly to the case of the rectangular notch, a cutting blade mold having the notch at the end as the shape can be made and cut by press-type pressing or the like. However, the limit of pressing is one to several cuts.
In the case of this triangle (wedge shape), since the cut line of the notch part is two straight lines that intersect at the back side, a medium holder without a notch part is prepared, and for example, a straight line with a device such as a yarn saw machine It is possible to cut and form a notch. With this method, it is sufficient to prepare only one type of cutting blade mold for producing a medium holder by press-type pressing or the like without a notch. Furthermore, if it is an apparatus like a yarn saw machine, it is possible to stack a larger number of sheets and collectively cut the cut-out portion, so that the manufacturing efficiency is very good.

[Example 3 U-shaped notch]
FIG. 10 is a diagram illustrating the shape of the medium holder according to the third embodiment (U-shaped). FIG. 10A shows the surface side, that is, the side on which the stamping material is placed. FIG. 10B shows an AA ′ cross section. FIG. 10C shows the back side. As shown in FIG. 10, the medium holder shown in FIG. 4 is the same as the medium holder except for the shape of the notch.
As shown in FIG. 10, the shape of the notch is a round shape (U-shape) on the inner side. In the case of this shape, similarly to the case of the rectangular notch, a cutting blade mold having the notch at the end as the shape can be made and cut by press-type pressing or the like. However, the limit of pressing is one to several cuts.
In the case of this round shape (U-shape), a medium holder having a shape without a notch is prepared, and can be formed by milling using an end mill blade in an apparatus such as a milling machine. With this method, it is sufficient to prepare only one type of cutting blade mold for producing a medium holder by press-type pressing or the like without a notch. Furthermore, if the device is a milling machine, it is possible to stack a larger number of sheets and collectively form the cutout portion, so that the manufacturing efficiency is very good.

Example 4 Cutout Structure
FIG. 11 is a diagram illustrating the shape of the medium holder according to the fourth embodiment (folding structure). A cut line of perforation is provided in advance in the cutout portion, and a necessary portion is cut out (broken and cut off). In the case shown in FIG. 11, the three places of the folding parts 41, 42, and 43 can be broken by perforations. There are three ways to break only one of the three breakers, three ways to break two, and one way to break three, so there are seven variations. Accordingly, it is possible to cope with the seven sizes of the stamp material.

Example 5 Insertion / Removal Structure
FIG. 12 is a diagram illustrating the shape of the medium holder according to the sixth embodiment (insertion / removal structure). Like a jumper pin, it is a structure that can be inserted and removed as many times as necessary.
The plugs 51, 52, 53 are provided so that they can be connected by pins 61, 62. Therefore, the insertion / extraction portions 51, 52, and 53 can be extracted and inserted any number of times. The connection pins are embedded in the insertion / extraction portions 51, 52, 53, and a structure in which notches of any combination can be formed and changed can be formed by inserting / removing a member for closing the connection pins.
The length of the pins 61 and 62 is set to a length that does not affect the detection by the sensor 3, or only a hole for inserting a pin on the medium holder side and embedding a connection pin on the side of the insertion and removal portions 51, 52, and 53. It is also possible to shorten the depth of the member to be closed by providing. As shown in FIG. 12, in the configuration in which three plug-out portions are provided as shown in FIG. 12, variations in which seven cutout portions are formed as in the fifth embodiment are obtained. In addition, in the case of the fifth embodiment, the take-off portion once broken can not be attached again, but in the sixth embodiment, repeated insertion and removal is possible.

  In the above embodiment, the medium holder is described as two thick paperboards. However, the present invention is not limited to this, and the medium holder may be provided with a positioning recess for fixing the stamping material. Alternatively, if the position can be fixed at the time of plate making, it does not have to be a hole or a recess. The position may be fixed.

  The material of the medium holder is not limited to the coated ball described in the above embodiment, and may be appropriately changed as long as the stamp face material can be fixed in position and can be stably conveyed during plate making.

  Furthermore, the film covering the surface of the medium holder is not limited to covering the entire surface of the medium holder as described in the above embodiment, and the stamp material can be fixed in position and can be stably conveyed during plate making. If present, only a part of the stamping material and only a part of the periphery of the stamping material may be covered. And in the said Example, although it is supposed that a film is adhere | attached with the double-sided adhesive sheet on the whole surface surrounding a printing material of a medium holder, it is not restricted to this, For example, the film to the conveyance system front half part is a printing surface. Adhering to the surface of the material with a double-sided adhesive sheet, the remaining film in the latter half is covered but not adhered, so that the stamping material can be freely attached and detached over and over again.
