Although it is not always necessary, if a printing device 6 including a laser printer, an ink jet printer, a thermal transfer printer or the like is provided, it is convenient to check a composition and to prepare a label to be attached to a grip end of a stamp.

[0006] In order to create a stamp composition, a stamp form creating means, a layout creating means, a stamp face creating means,
A stamping surface adjusting means and a composition integrating means are used. The stamp face forming means selects the shape of the stamp face such as square, rectangle, round, oval, and oval, the direction of the stamp face such as vertical writing and horizontal writing, and the size of the stamp face from large to small. This is a means for reading the imprint form conforming to this from the storage device and developing it on the display device. Therefore, the developed stamp form determines the basic elements (shape, direction, size) of the composition. The layout creating means is means for developing a layout for appropriately arranging characters and graphics (including lines, frames, symbols, images, and the like) on the stamp surface form,
A layout patterned in advance to correspond to the stamp face form is registered in the storage device, and when a stamp face shape, a stamp face direction, and a stamp face size are selected, several layouts adapted to these are developed on the stamp face form. In addition, a tool is provided which allows the user to select a desired one or arrange characters and graphics on the stamp surface form. The stamp face creating means is a means for synthesizing a stamp face according to the layout with characters or figures actually input. The stamping surface adjustment means includes changing the typeface of the character, changing the series of the character, changing the aspect ratio of the character, changing the space between the characters, moving the character up, down, left and right
Adjustment means for changing conditions such as a change in line end processing, a change in frame angle processing, and enlargement / reduction of a figure. The composition integration means,
This is a means to integrate multiple composition data after formatting into one batch.

[0007] A flowchart of an example of the composition creation (FIG. 2)
Shown in When an instruction to start the composition is issued with the input device 2 such as a mouse (S101), the processing device 5 reads the program stored in the storage means 4 and displays the stamp type selection screen (FIG. 3) on the display device 3. (S102). The stamp type selection screen allows you to select the stamp face shape such as square, rectangle, circle, ellipse, and oval, the stamp face direction such as vertical writing and horizontal writing, and the stamp face size at a time. When a command is issued with a mouse or the like (S103), a suitable stamp form is read from the storage device based on the determined conditions and is developed on the display device. At this time, since the layout patterned in advance to correspond to the stamp form is registered in the storage device, when the stamp shape, the stamp direction, and the stamp size are selected, several layouts that match the selected stamp form are displayed on the stamp form. Is displayed on the display device, and a layout selection screen (FIG. 4) is displayed so that it can be further selected (S10).
4). Next, when a required layout is selected from a plurality of layouts on the layout selection screen and commanded with a mouse or the like (S105), the processing device 5 creates a field for inputting characters and graphics according to the selected layout. A character input screen (FIG. 5) including a preview area for displaying a preview of the stamp surface to be displayed is displayed (S106). Next, when characters or figures to be stamped are input to the respective fields using the keyboard or the like of the input device 2 (S107),
The processing device 5 develops the characters and graphics in accordance with the layout selected earlier to create a stamp, and displays a preview of the stamp in the preview area (FIG. 6, S108). Next, if you want to modify and change the font, layout, etc., switch to the adjustment screen (Fig. 7), specify the line of the character bar you want to adjust, and change the character series and the aspect ratio of the character. Then, the character is directly designated with a mouse or the like and moved up, down, left, and right to adjust the appearance (S109). The preview is checked again, and if there is no need to readjust the stamp face, the creation of the composition is completed (S110). When the composition is to be saved, a save command is input, the stamp is fixed, and at the same time, the composition is filed and stored in the storage device 4. The file format is a resolution of about 600 to 2400 dpi, such as image file formats such as Microsoft BMP files, ISO standard JPEG files, Compuserve GIF files, Adobe Systems TIFF files, and Apple Computer PICT files. , A file format in which information such as fonts, ruled lines, and arrangements are coded. By repeating the above operation, a plurality of composition can be created.

Next, another example of the composition creation is shown in a flowchart (FIG. 8). When an instruction to start the composition is issued by the input device 2 such as a mouse (S201), the processing device 5 stores the
Is read, and a stamp type selection screen (FIG. 9) is displayed on the display device 3 (S20).
2). The stamp type selection screen allows you to select the stamp face shape such as square, rectangle, circle, ellipse, and oval, the stamp face direction such as vertical writing and horizontal writing, and the stamp face size at a time. When a command is issued with a mouse or the like (S203), a suitable stamp form is read from the storage device based on the determined conditions and is developed on the display device (S204). In the present embodiment, a grid in a grid pattern appears, and the dimensions actually cut and the maximum range in which the stamp surface can be formed are represented by thin lines (FIG. 10). Next, a layout is created (S205). When the drawing mode 7 is selected from the toolbar (FIG. 11) and the start point and the end point are determined on the grid with a mouse or the like, characters and figures can be input. In the present embodiment, a horizontal line or a vertical line can be drawn by selecting the straight line drawing mode 8 and setting the start point and the end point on the grid with a mouse or the like, and selecting the square drawing mode 9 and setting the start point on the grid with the mouse or the like. If the end point is set, a square or a rectangle can be drawn. If the round drawing mode 10 is selected and the start point and end point of the rectangle are set on the grid with a mouse or the like, a perfect circle, an ellipse, and an arc inscribed in the rectangle are drawn. If the character drawing mode 11 is selected and the starting point and the ending point are set on the grid with a mouse or the like, characters can be input in the field. If the start point and the end point are set, a perfect circle or ellipse inscribed in the rectangle can be drawn, and characters arranged along the circle can be input. Next, characters or graphics to be used as a stamp surface are input using a keyboard or the like to actually create the stamp surface, and when the input is completed, a data input completion command is input (S206). Then, the processing device 5 synthesizes the input character or graphic data with a frame line such as a straight line, a rectangle or a circle to create a stamp (FIG. 12), and displays a preview of the stamp (S207). Next, a means for correcting / changing and adjusting the stamp surface will be described (S208). If you want to adjust the line or frame line, re-specify the line or frame line with the mouse or the like, and the properties as shown in Fig. 13 and Fig. 14 are displayed. You can change the line thickness, fill, and round the corners of the frame line. it can.
If you want to adjust the character, re-designate the character or graphic field with a mouse or the like, and the properties shown in Fig. 15, Fig. 16, and Fig. 17 are displayed. , Layout, the starting angle of the circulating character, the orientation of the circulating character, and the like. The preview is checked again, and if there is no need to re-adjust the stamp face such as correction / change, the creation of the composition is completed (S209). When the composition is to be saved, a save command is input, the stamp is fixed, and at the same time, the composition is filed and stored in the storage device 4. The file format is a resolution of about 600 to 2400 dpi, such as image file formats such as Microsoft BMP files, ISO standard JPEG files, Compuserve GIF files, Adobe Systems TIFF files, and Apple Computer PICT files. , A file format in which information such as fonts, ruled lines, and arrangements are coded. By repeating the above operation, a plurality of composition can be created. FIG.
Is an illustration of this embodiment.

[0009] Although the composition outputted to the above-mentioned file can be used one by one, it is preferable to integrate a plurality of composition into one batch because the production efficiency is improved. FIG.
9 is a flowchart of the present invention. When a command to start the composition is input with the input device 2 such as a mouse (S301),
The processing device 5 reads the program stored in the storage means 4, first creates a composition integrated screen (FIG. 20), and displays it on the display device 3 (S302). A grid-like grid is shown on the composition screen. Next, a file reading mode is designated from the toolbar, and necessary composition files are read from the storage device 4 (S303), and a composition list (FIG. 21) is displayed on the display device 3 together with the composition integration screen (S304). Next, the necessary composition is arranged on the composition integration screen by drag and drop (S305). Step S305 is repeated a plurality of times, and the composition files desired to be batched are developed on the composition integration screen (FIG. 22). Next, in order to make effective use of the batch surface, the composition is moved so as to eliminate the margin as much as possible (S306), and the batch is completed. Each of the read composition is activated by selecting and redesignating the composition with a mouse or the like, so that the composition can be freely moved. Here, if you want to modify the stamp, you can use paint software if the composition file is in the image file format, and if the composition file is in the code format, use the mouse to copy the individual composition. If the user selects and re-designates, the program of the first or second embodiment is started, and the font of the character, the top and bottom, right and left of the character string, long / flat body, arrangement, etc. can be adjusted again. Next, the preview is checked again, and if there is no need to modify / change, the creation of the batch is completed (S307). When saving the batch, a save command is input, the stamp face is determined, and at the same time, the composition is filed and stored in the storage device 4. File format is 6.
An image file format of about 00 to 2400 dpi or a file format in which information such as fonts, ruled lines, and arrangements are coded can be used. FIG. 23 shows the output of the batched file to the printer. By making the margins (unnecessary parts) black, it is possible to improve the production efficiency when creating a stamp using the corresponding composition. In addition, since the individual composition is created in an image file format of 600 to 2400 dpi, when the individual composition is displayed on the display device at the resolution at the time of batching, an excessive load is applied to the processing device. In addition, there is a problem in that the process of developing a batch to be composed on the composition integrated screen cannot be performed smoothly, and the processing time becomes longer. Therefore, in the present invention, the resolution (100 dp) specific to the display device is used.
i)) is used for the screen display using the electronically converted composition,
The original resolution composition is temporarily stored in a memory. As a result, a plurality of artworks are displayed on the display device at the resolution of the display device, and the images are developed on an integrated artwork screen, moved freely, and positioned. On the other hand, in the memory, the original resolution composition is arranged at the same position as on the display device, so that batch processing can be performed without reducing the processing speed.

Next, a description will be given of a stamping surface forming apparatus including a control device and a laser processing machine. 501 is a main body,
Inside the laser oscillator 504, dust collector 505, deodorizer 5
06, a suction machine 507 and the like. Reference numeral 502 denotes a cover, which is made of a material that does not allow a laser beam to pass therethrough. The cover 502 is closed during emission of the laser beam. 5
03 is a table, on which rail 511 is X
Two are installed in the axial direction (sideways). Reference numeral 512 denotes an arm, which is installed in the Y-axis direction (vertical direction) perpendicular to the rail 511, and has a shape in which support columns are provided downward from both ends. The arm 512 is movable in the X-axis direction by arranging the support column so as to be movable along the rail. 513
Is a head portion movably supported by the arm 512, and is movable only in the Y-axis direction. The head unit 513 has a nozzle 514 including a fixed mirror 515, a lens 516, and a firing port 517.
The suction hose 515 is also supported and fixed. A reflecting mirror 519 reflects a laser beam emitted from a laser oscillator in parallel to the rail 512 via a plurality of mirrors. Reference numerals 520 and 521 denote a movable mirror A and a movable mirror B provided at the end of the arm. The laser beam reflected from the reflection mirror 519 is reflected by the movable mirror A 520 and the laser beam is reflected by the movable mirror B5.
Then, the laser beam reflected by the movable mirror B 521 is reflected by the fixed mirror 515. In addition, the table 503 has an infinite number of holes formed in the center thereof. After the stamping material is placed thereon, the stamping material is sucked from below the table to fix the stamping material. The table on which the stamp is placed can be moved up and down, and can be moved up and down so that the distance between the ejection opening 517 and the surface of the stamp is maintained at 1 inch. Reference numeral 508 denotes a control device which issues a control command for laser processing, and performs operations such as conversion of the composition data into an executable file, detection of a processing position, laser on / off operation, laser output control, and tuning of various devices involved in processing. In the present embodiment, the control device 508 is connected to the main body 1 by a cable, but may be connected via a network or the like, or may be built in the main body 501.

Next, preparations before starting the laser beam machine will be described. First, the optical axis of the laser beam is adjusted. Each movable mirror is designed so that the mirror itself can be rotated by 360 ° and the column itself that supports the mirror can also be moved in the X and Y directions. First, after the head is moved to one end of the arm, the fixed state of the movable mirror B is released, and then the movable mirror A is adjusted so that the laser beam hits the center of the fixed mirror. next,
The head is moved to the other end of the arm, the movable mirror B is unlocked, and the laser beam is adjusted and fixed so as to hit the center of the fixed mirror. When the adjustment of the mirror is repeated several times while moving the head, the laser beam can be focused on the center of the fixed mirror regardless of the position of the head. If the number of movable mirrors is one as in the related art, the adjustment is extremely difficult, and the center is often shifted depending on the position of the head part, which causes the processing accuracy to be greatly reduced, but the laser beam crosses the movable mirror. By installing two such optical axes, the optical axis can be easily adjusted in a short time.

Next, a method for engraving a stamp surface using a laser beam machine will be described. The composition created by the composition creation device or the composition created in batches is stored on a floppy disk, L
Read into the control device 508 via an AN cable or the like,
The composition data is displayed on the display device 509 as an image. At this time, if necessary, the read image file is enlarged or reduced and displayed. Next, a stamping material (here, a vulcanized porous NBR rubber sheet having a thickness of 2 mm was used) is placed on a table 503 of a laser processing machine, and the cover 502 is closed. Next, when the start of engraving is commanded, the laser oscillator 504, the dust collector 505, the deodorizer 506, and the suction device 50
7. Electric power is supplied to the compressor and the like, and the stamp is fixed to the table by suction from below the table. Next, the control device analyzes the composition data according to the stamp processing control program, and creates an execution file to which a spread angle is added to the outside of the composition. This is the Japanese character No. 54-34651.
This is a measure taken to form a normal typeface so that the divergent angle θ2 of the peripheral edge of the base end portion is larger than the divergent angle θ1 of the peripheral edge of the distal end portion.
The steps are carved in multiple steps as shown to express the spread angle θ2. After the execution file is created, the head unit 513
Is set at the initial processing position, and a portion corresponding to a blank portion (usually a white portion) under the plate is traced on the printing material in the Y-axis direction while setting the laser output to 100%. When the tracing for one dot is completed, the tracing is moved by one dot in the X-axis direction, and the tracing is performed in the Y-axis direction for one dot. When the head 513 approaches the base end, the laser output is reduced so as to form the divergent angle. The laser output is set to 0% in a portion corresponding to a stamped portion (usually a black portion) under the plate. A suction hose 518 is fixed to the head portion 513, and at the time of the above-mentioned processing, the dust burned by the laser beam is immediately sucked to prevent the scattering of the dust and to suck the odor. Through the above steps, a stamp surface having a cross section as shown in FIG. 26 could be engraved.

Next, the engraved sheet is taken out, and the sheet surface and the inside of the sheet are washed with a washing machine to remove rubber dust and carbon dust. Next, after drying the sheet with a dryer, cut it into a required shape with a punching die, impregnate it with an ink with an ink impregnating machine, and assemble it with a holder. Complete.

In the present invention, natural rubber is used as the material of the stamp material.
Various thermoplastics including rubbers such as acrylonitrile butadiene rubber, styrene butadiene rubber, butyl rubber, chloroprene rubber, silicone rubber, thermoplastic resins such as polyethylene and polypropylene, and olefinic thermoplastic elastomers composed of polyethylene and ethylene-propylene rubber An elastomer or the like can be used. In addition, not only a porous material, but also a stamping material (non-porous body) using a stamping material of the above-mentioned material and making it non-porous,
It is also possible to create a stamp face using a plastic board, a wood board, a stone board, or the like. In this case, the stamp is completed by cutting into a required shape after engraving and pasting it on a wood or plastic holder as it is. In addition, the plate making device and the control device can be shared without preparing each.

[0015]

According to the present invention, by using a computer and a laser processing machine in a unified manner, the plate making process and the stamp surface making process can be unified, so even when only one stamp is made, it is quick and inexpensive. , Stamps can be easily manufactured.
