Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to printing resetting, and relates to a printing device that performs white printing as a bold printing method for emphasizing specific characters.

According to the following, bold printing methods for emphasizing specific characters include: [1] changing the printing color of specific characters to distinguish them from others (for example, printing in red), and 2) adding symbols to the characters. For example, as shown in Figure 1a, add parentheses, under fins, dots, or surround it with a frame. After printing, shift the pitch slightly and then double print. For example, as shown in Figure 1b, the letter A is printed twice or more with a slight shift, or the pitch of the '41 character interval is changed, for example, as shown in Figure 1c, only the letter is printed A method of printing with a larger spacing than that of
As shown in Figure d, a method of printing using Gothic or italic type; t6} A method of printing by slightly shifting the line by slightly feeding the paper, e.g., as shown in Figure 1 e. As shown, there are methods of printing only the letter A by shifting the lines, methods of printing by changing the shading of the '7 leg, for example, a method of striking only a specific character twice, and a method of using a specific typeface with a leg "L" shape. , after creating a solid area by printing with a shift of 1/120 inch,
There is a white printing method in which character shapes are removed using correct tape. These bold printing methods can be used effectively depending on the type of printer.

However, the number of characters that can be accommodated is limited (approximately 100 characters) in type-type impact serial printers, especially in types outside of type printers that transfer characters by hitting the type housed in a print wheel. Unlike wire dot printers, it is not possible to freely change the size of characters or increase the width of lines. Also, if a large number of different typefaces for emphasis are accommodated in the same wheel, the number of typefaces will inevitably increase, so the diameter of the wheel should be increased or
Two or more wheels must be provided, and the increased rotational inertia makes it difficult to control the positioning of type selection.
The structure becomes complex and large. Therefore, as a method of emphasizing printed characters using the same printing hole, the above-mentioned '
The method of changing the printing color in 1' and the method of using a different typeface in [5] cannot be adopted. However, the aforementioned ■～■,■,
Since the degree of emphasis on specific characters is low in , it is desirable to at least change the print color as described above, or use a printing method with a high degree of emphasis similar to the method using SU typeface. . Therefore, the above-mentioned {8) white printing method is attracting attention, but it requires shifting in 1'120 inch increments using a specific "L"-shaped typeface.
The drawback is that it takes too much time to form a solid black color.

In view of the above-mentioned situation, an object of the present invention is to provide a printing device that can print both normal characters and highly emphasized white characters with a simple structure using the same printing wheel. It's about doing. Furthermore, another object is to form a continuous background portion long enough to print a plurality of characters and perform whiteout printing, thereby achieving more emphasized and beautiful whiteout printing. In order to achieve the above objectives,
The printing device of the present invention is a serial impact printer having a printing element with a plurality of printed characters. A tape having a magnetic property, a rod-shaped or rectangular type provided on a printing element, and a width wider than the width of the rod-shaped or rectangular type by shifting the position and impacting the ink ribbon with the rod-shaped or rectangular type. The present invention is characterized in that after forming a background portion having a background portion on a printing paper, characters are printed on the background portion through a tape having pre-adhesive properties, and a control means is provided for peeling off the ribbon ink from the background portion. be.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a side view of the printer of the present invention. When performing normal printing, the printing type 2' housed on the outer periphery of the type wheel 2 is hit from behind with the printing hammer 3 using the ink ribbon 1 as a medium.
The print is transferred onto the surface of the print paper 4 wound above.
Further, an adhesive tape 5 is arranged below the ink ribbon 1, and both are wound up by a winding mechanism (not shown) and moved up and down by a shift mechanism, so that they are placed in front of the type portion 2'. The position can be changed freely. Figure 3 shows the type of the present invention.
It is an explanatory view of a wheel and white printing.

The type wheel has fingers 2 extending radially, as shown in FIG. Type 2' is selected.

In the present invention, a type body 8 is provided on the wheel 2 so that a solid black portion can be printed in one printing.

The solid black transferred by the typeface 8 becomes the base for white printing. When printing with white outline,
First, the solid black type 8 is selected in the state shown in FIG. 2, and then solid black is printed on the surface of the printing paper 4 by striking the black type 8 through an ink ribbon.

Next, rotate finger 2 to select the desired type 2' to be emphasized.
At the same time as selecting , the shift mechanism is operated to shift the adhesive tape 5 upward and the ink ribbon 1 downward, and then the selected type 2' is struck from the rear of the adhesive tape 5. Only the protruding parts of the letters on the adhesive tape 5 are adhered to the black part of the surface of the printing paper 5. Note that a space operation is performed after normal printing, but in the present invention, a space operation is not performed after printing the solid black characters 8. Therefore, when the adhesive tape 5 is hit, the solid black characters 8 are printed in the same manner as the black areas. You will have to hit the position. As a result, the ink from the solid black part to the area of the type becomes sticky. It transfers to the surface and is peeled off. As a result, the ink on the protruding portions of the letters to be emphasized runs out, and the paper surface bulges out in those portions of the solid black portion, making it possible to form white print. In FIG. 3b, in order to print the emphasized word "tioe", the above-described operation is repeated in the line direction one character at a time, thereby printing an outline.

By performing white printing as described above, emphasized characters can be expressed by only adding one solid black type character 8 and by performing two operations for each character.

Note that as for the adhesive tape 5, a conventionally used correction tape can be used as is. FIG. 4 is a control system block diagram of the printing apparatus of the present invention, and FIG. 5 is an explanatory diagram of selection data transferred to the printing apparatus of FIG. 4.

In FIG. 4, the character selection portion of the type wheel and the carriage movement portion are shown. Selection data is sequentially transferred from the CPU I to the interface unit 12 in correspondence with the characters to be printed.

These selection data are directly converted into a dress indicating the position of the type on the wheel section and input. Since the number of characters in the case of a normal petal-shaped wheel is 96 to 10 characters, 7 bits are sufficient as an address code. In data transfer from the CPU II, 8 bits are treated as the minimum unit, so in the present invention, 7 bits are used for character selection, and the remaining 1 bit is used as a bold flag to cancel spaces after printing, and to cancel the space above and below the adhesive tape. Used for control.

In FIG. 5, the wheel address "0000000" is an address in solid black type, and addresses in other type are shown in parentheses, such as (t), for simplicity. As shown by “tMe” in Figure 3b,
When performing black and white inverted bold printing, the selection data shown in FIG. 5 is sequentially transferred from the CPU 1 to the interface unit 12 starting from the right column. First, the black type is selected by "00000000" in the right column, and the black part is printed, but since the bold flag of the next selection data is "1", the space operation after printing is It won't happen. Next, the character t is selected by the wheel address of (t), but since the last bit is "1", the adhesive tape is shifted up and the character t is hit, so that the character t is selected. Outline characters are formed. The next bold flag is “01, so
A space motion is performed. Next, the black type is selected again, and after printing, the spaces remain canceled,
By hitting the letter i from above the adhesive tape,
An outline character "i" is formed. These operations are repeated in the same way. In FIG. 4, the CPU 11
The selection address information transferred from the interface section 12 is temporarily stored in the buffer 22 of the interface section 12, and is transferred to the selection buffer 13 by the selection start signal NI.
2 requests the next selection address information from the CPU
I and stores the next information in the buffer 22.

On the other hand, the character counter 15 is incremented or decremented by a direction signal (not shown) in synchronization with the excitation counter 16.

That is, when the character selection motor 9 rotates as the excitation counter 16 advances and the reference position is detected, the character counter 15 is reset by the detection signal N2.
This character counter 15 is always type. It is synchronized with the rotation of the wheel. When new information is stored from the buffer 22 into the selection buffer 13 in response to the selection start signal NI, the match circuit 14 determines whether the contents of the selection buffer 13 match or do not match the contents of the character counter 15, and outputs N3. occurs.

When there is a mismatch, N3 is "0", and by opening the gate of the clock through the inverter G2, the gate output N4 counts up or down the character counter 16 and the excitation counter 6 at the same time.
Counting is continued until the match circuit 14 detects a match. The character selection motor 9 continues to rotate and the wheel continues to rotate until a match is detected. Matching circuit 1
If a match is established at 4, N3 becomes "1", so the character counter 15 and excitation counter 16 stop counting, the wheel rotation also stops, and the interface unit 12 is notified that the selection operation has been completed. Then, control moves on to the next hammer operation, bong operation, etc. The basic operation of an impact type serial printer is to perform a space operation after a printing operation and move the carriage to the next printing position, which is a repetition of printing and spacing. Therefore, after the printing operation, a space start signal N5 is generated. The space motor 10 is driven by the space control circuit 18.

In the case of normal printing, the above operation is repeated, but
In the case of black and white reversal pole printing according to the present invention, in addition to this operation, an operation of driving the lift magnet of the adhesive tape TP is added.

When the data string shown in FIG. 5 is transferred, first, by setting the wheel character address "00000001" in the selection buffer 13, it matches the character counter 15 and prints black characters. Since the character address t to which the bold flag "1" has been added is set in the buffer 22, the space start signal N5 is canceled through the inverter G4, and no space operation is performed after solid black printing. , move on to the next t printing cycle. When the t-print address with the bold flag is transferred to the selection buffer 13, the bold flag output signal N6 drives the magnet driver 17, and the tape lift magnet TP is
, the adhesive tape is selected in place of the printing ribbon.

- By performing the printing operation via the adhesive tape, only the character t is peeled off from the previous solid black printing surface, and black and white reversal printing is realized. The space operation at this time is
Since the content of the buffer 22 is the next black print address (0) and the bold flag is "0", the space control circuit 18 drives the space motor 10 without being canceled. rotates and the carriage moves directly to the next printing position. Similar operations are performed for i, t,
By repeating steps ``a'' and ``e,'' the outline characters shown in FIG. 3b can be expressed. In the above explanation, white printing is performed using solid black type for each character, and the spacing operation is performed in the same way as normal printing, so the spacing distance cannot be adjusted arbitrarily.

In other words, as shown in FIG. 6a, the white characters printed by the wheel in FIG. 3a have spacing between the solid black characters because the amount of spacing There is. In the present invention, it is assumed that the required minimum width of solid black type is 10/120 inches, and that the minimum spacing resolution, that is, the minimum amount of space available, is 1/I20 inch. Now, in order to further increase the emphasis level of continuous white characters, when trying to express white print with continuous solid black parts as shown in Figure 6b, the spacing amount x that does not overlap the solid black parts is
is 10/120 inches.

Furthermore, as shown in FIG. 6c, the spacing amount when the character spacing is increased in the space direction with continuous solid black portions is 10/120×n inches. therefore,
When using the wheel shown in Figure 3a to widen the character spacing in the direction of spacing to form a lotus-based evening black part, the amount is 10
/120×n (n is an integer), which is fixed to some extent. Therefore, in the present invention, as shown in FIG. 8, the standard black type 8, the minimum line width black type 8', and the 1/Z standard black type 8 are housed in the wheel.

Here, the minimum line width is the core line width of 1/120 inch corresponding to the minimum disassembly of the carriage, and the 1/2 standard black width is 10/120 inch x 1/2. These three types of black print 8, 8', 8^ are [1], [2], [3]
If so, by combining them singly or alternately, it is possible to arbitrarily specify the character spacing as well as the printing, and it is possible to form any continuous solid black area.
FIG. 7 is a diagram showing an example of white characters printed by a combination of three types of solid black type.

In FIG. 7a, the character spacing is specified as 13/120 inches, and solid black type [1] and evening black type [2] are printed to form a lotus and evening black part. In addition, in Fig. 7b, when the character spacing is specified as 16/120 inches, solid black characters [1], [2], and [3] are printed in combination to form a dark area. There is. Here, [3]
The reason for having 1/Z standard black type is to ensure high speed printing and beautify solid black areas, which cannot be achieved with only 4 line width and black type in [2]. be.

In this way, by providing one or more rod-shaped type bodies having a core line width that is an integral multiple of the scanning resolution of the standard black type and the carriage body as the type body for solid black printing disposed in the wheel. , it is possible to realize the Yukurobe text with arbitrary character spacing.

The above is a case where multiple solid black type characters are combined to form a dark black part, but if you form a solid black part in an unbroken band, it becomes possible to beautify the solid black part, and it is possible to Since only one operation is required, it is possible to shorten the time required for printing white outlines.

This case will be explained below. Fig. 9a shows a case where white inversion printing is performed using the solid black type shown in Fig. 3a, and Fig. 9b shows a case where white inversion printing is performed using the same flat black type to further increase the degree of emphasis. FIG. 12 is a diagram showing a case where words and sentences are printed in white uniformly in one solid black band in a band-like manner according to the length.

FIG. 10 is a block diagram of a CPU and a print control circuit for explaining the print control method shown in FIG. 9b.

The information transferred from the CPU II to the print control circuit 19 basically consists of a function code meaning printer operation and data discrimination, and data information corresponding to the function code.

The print control circuit 19 is provided with a register 190 for storing a function code, a register 191 for storing the amount of space for space operation after printing, and a register 192 for storing print character information, and the output of the register 192 is sent to a code converter. 193, it is converted into a printed address of the wheel.

First, normal printing operation will be explained.

CPUI I program counter register 118
The system sequence operation progresses according to the contents of A and after the printer section setup arrow is completed.
A code specifying the data register 191 to the print control circuit 19 from the register 113 is transferred to the register 191, followed by the character pitch information at that time.

Next, in preparation for transferring the print character information, the CPU II sets the address where the print information in the memory 20 is stored in the X register 116 and the Y register 117 and reads it from the memory 20. The read head information is transferred to the A register 113 via the data bus 21.
Immediately after this, the X, Y registers 116 and 117 are incremented. When the ready signal from the print control circuit 19 turns on, it is paired with the function code that specifies the data register 192 and the A register 1 1
The printing operation is executed by transferring the information No. 3 to the data register 192 and simultaneously transferring the print start information to the function register 190.

The contents of the registers 191 and 192 remain unchanged unless they are re-specified from the CPU II.

Therefore, in the case of continuous printing at the same pitch, information specifying the register 192, character information, and print start information are transferred in synchronization with the ready signal.
Printing continues. Furthermore, when only printing start information is transferred, the same pitch and the same characters are continuously printed. Next, a black and white interpolation printing operation as shown in FIG. 9b will be explained.

Now, assume that the normal printing pitch is 12/120 inches, and the width of the total black type on the wheel at that pitch is 10/120 inches.

CPUI I program counter register 118
When the printing operation specified by the system sequence is started, the printer section is set up, and then
The contents of the addresses designated by Y registers 116 and 117 are transferred to A register 113.

At this time, the least significant bit (MSB) of the character information is used as a bold flag specifying reverse printing as described above, and this bold flag is detected in the A register 113. FIG. 11 is a diagram showing the contents of the memory in the case of reverse printing. Character information for t is stored at address X, character information for i is stored at address X+1, and character information for t is stored at address x12.

Assuming that address (t) is now transferred to the A register 113, the bold flag BOLDFLG is detected here and the next task is executed based on the program sequence.

In addition, each register 110, 111 of S1, S2, S3,
112 is set to an initial value of 0. [1] Add "12" to SI register 11.

■ Add "10" to the S2 register 111. '3
Add “1” to the 1S3 register 112. '4' Set '10' in the register 191 of the print control circuit. {51 Peta After setting the black print information in the register 192, print start information is set in the register 190.

'61 (After the second time, {
41 and '5} registers are not required).

When the bold flag (BOLDFLG) becomes "0", the following operation is performed.

[7' Add "10" to the S2 register 111.

'81 Set print start information to register 19. [9} Compare the contents of the SI register 110 and the contents of the S2 register 111, and in the case of SIZS2, the above '
71 to '9} are repeated, and in the case of SISS2, move to the next operation.

00 The A register 113, the arithmetic unit 115, and the carry/borrow 114 are used to calculate (S2-SI)÷S3, and the result is set in the A register 113.

Here, S3 is the number of characters to be printed in reverse, and the calculation result is rounded to the first decimal place, so how much should be added to the standard "12" for the space between characters for white printing? I am deciding what to do. (11) Store (contents of 120A register 113) in S3 register 112.

(Set the back space of 1 no print in the register 190, and set the print start information in the register 190.)
'Set this.

At the same time, "10" is subtracted from the contents of the S2 register 111. When this is continued until S2 becomes 0, the print head returns to the beginning of the evening black belt and waits. (13 Next, the X register 116 is decremented, and at the same time "12" is subtracted from the SI register 110.
This continues until the value becomes 0, and when the X register 116 is decremented once, the address in the memory 20 returns to the address x in FIG. (Specify 1-core forward printing and adhesive tape and set the contents of S3 register 112 in register 191.

(15) The A registers 1 to 3 of the CPU I perform normal printing operations while detecting the bold flag BOXDFLG. In the example of white printing shown in FIG. 9b, the calculation result of the above-mentioned (10) is as follows.

{70(S2)-60(SI)}÷5(S3)=2(A
register)...t1) Therefore, the character pitch of the printing operation in (15) is 122=14, and continuous white characters are expressed at a pitch of 14/120 inches. By the way, the white-out printing of the present invention that has been explained so far is performed by repeating a white-out operation after printing solid black, or a continuous white-out operation after printing a lotus-like evening black. .

Normally, in such printing devices, printing quality is given top priority, so a method is adopted in which the printing energy is changed according to the type area and the pressure applied per unit area is constant. Small “M”, “W” etc.
The printing energy is changed depending on the character in about 6 to 8 steps up to the period. According to this idea, the area of a solid black area is much larger than that of "M", "W", etc., and therefore requires a correspondingly high amount of printing energy, which leads to smaller hammer shapes and lower cost drive circuits. This is an extremely disadvantageous condition for Therefore, in the present invention, by performing continuous impact multiple times with a printing energy of about "M" or "W", the same effect as printing with a high printing energy can be obtained.

This increases the reliability of solid black printing and improves printing quality. FIG. 12 is a block diagram of the peripheral circuit of the hammer part in the printing device of the present invention.
FIG. 3 is an operation time chart in FIG. 12.

The operation of each component in the printer's printing operation,
For example, the operations of the carriage feed mechanism, character selection mechanism, hammer, ribbon, line feed, etc. are executed serially or in parallel by the print control circuit 19 according to the CPU II sequence shown in FIG.

FIG. 12 shows the circuit of only the hammer portion in each component. By command of CPUI I, HMI~
Hammer-on signal HM-ON along with printing information of HM3
When is issued, the bold flag 80LDFLG is "0" (low level) in the case of normal printing, so
Monostable circuits 32 and 33 are in the reset state and node N
1 and N3 are fixed at the /.i level.

Therefore, the hammer-on signal HM-ON is input to the printing pressure control circuit 34 through the inverter G1 and the NOR gate G3, and a predetermined voltage is applied to the node N2 to turn on the transistor Tr and cause current to flow through the hammer magnet. Perform normal hammer action. The ready signal control to the CPU II is controlled by the monostable circuit 31 only by the hammer operation stabilization time signal N4.

On the other hand, during the black printing operation, the bold flag BOLDFLO becomes "1" (high level) and the reset state of the monostable circuit 32 is released, so that the A terminal of the monostable circuit 32 becomes high level. When the reset output NI falls from the low level to the low level, the reset output NI becomes "0" (low level) and drives the printing pressure control circuit 34.

That is, as shown in FIG. 13c, the bold flag BOLDFLG for specifying solid black printing becomes "1", and while the printing pressure information HMI to HM3 is valid (VALID),
When the hammer-on signal HM-ON in FIG. 13b becomes "1", the printing pressure control circuit 34 is immediately driven through the inverter GI and the gate G3, and the node N2 in FIG. 13e goes high. Set it to level and apply current to the hammer magnet. The monostable circuit 31 is set by the hammer-on signal HM-ON, and the set output is kept high for a certain period of time.
After setting the level, the monostable circuit 32 is set at the same time as the monostable circuit 31 is reset, and the reset output NI is set to "0".
” (low level), /A Gate G
3, the printing pressure control circuit 34 is again driven to apply current to the hammer magnet.

After the monostable circuit 33 is in the set state for a certain period of time,
Along with the reset, a ready signal is sent to the CPU II, and at the same time the hammer magnet current is stopped.

As shown in Figure 13e, one hammer-on signal HM
-ON automatically causes two hammer pulses to be output to node N2.

During this period, the ready signal READY is off and the CP
The UII is in a standby state.

In FIG. 12, two hammer operations are performed by one hammer command, but it is also possible to perform two or more hammer operations.

In addition, the operation of these monostable circuits 31, 32, and 33 is
It is also possible to realize this by program control of the PU. In addition, as a solid black typeface, bar-shaped typefaces with the same width (3/100 inch) as the spacing are spaced narrower than the standard black typeface (for example, 3'100 inch) and shaped into the tooth shape of a geta. First, the first printing operation prints the teeth of the geta, then the pitch is shifted by the distance (3/I00 inch), and the second printing operation fills in the gaps between the teeth of the geta. A complete pot is formed. In addition, it is also possible to provide three or more stick-shaped type characters in the tooth shape of geta in succession.

With this configuration, the printing area for one printing is small, so 1
Sufficient energy can be obtained by rotating the printing operation, and there is no need to degrade solid black printing quality. As explained above, according to the present invention, a solid black printing type is provided in the type housed in the wheel, and after printing a solid black part, emphasized characters are added to that part via an adhesive tape. Since printing is performed, outline characters can be printed at high speed without significantly increasing the number of printed characters accommodated in the wheel.
In addition, standard solid black type and narrower bar-shaped type are provided in the type housed in the wheel, or multiple bar-shaped type is shifted and printed twice to form a solid black area and then adhesive By printing the highlighted characters through the tape, it is possible to express white characters on the dark black part of the screen having arbitrary character spacing, thereby making it possible to further increase the degree of emphasis. Furthermore, according to the present invention, a command from the CPU to the print control circuit prints the length of a black and white inverted word or sentence in a continuous black band shape, and arranges each character evenly within the black band. It is possible to further increase the emphasis of words or sentences, improve printing speed, and improve the beautification of dark areas. Furthermore, in the present invention,
Since multiple hammer operations are performed during one solid black printing operation, solid black printing can be reliably performed without degrading the print quality as a typeface serial printer.
It is possible to realize white characters.
