Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a thermal transfer serial printer, in particular:
The present invention relates to an ink ribbon feeding method and device in a thermal transfer serial printer in which the entire ink ribbon moves together with the printing section.

Prior Art A printer in which the printing section moves left and right relative to the recording paper and prints by feeding the recording paper in a direction perpendicular to the movement of the printing section is called a serial printer.

These serial printers include the ink type ink ribbon, which prints by hitting the recording paper with type through an ink ribbon, the thermal printer, which uses thermal paper and a thermal head, and the thermal transfer ink ribbon, which is pressed onto the recording paper by a thermal head. There are thermal transfer printers that perform recording by melting ink on a thermal transfer ink ribbon using heat from a heating element of a thermal head.

Among these, in-press type and thermal type serial printers can easily perform bidirectional printing, which prints not only on the outward printing path but also on the returning printing path, so bidirectional printing is generally used as a means of speeding up printing. Many use .

Using Figures 1 (A) and (B), we demonstrated that this bidirectional printing method is effective in improving the average printing speed compared to the unidirectional printing method, which prints only on the outward path of the printing section. explain.

In Figure 1, reference number 1 is the recording paper, arrow 2 is the paper feed direction, solid arrows are the movement of the printing section during printing, and dotted arrows are the movement of the printing section when one line of printing is finished and the next line is moved. Indicates the moving route ◎ For those that can only print in one direction, as shown in Figure 1 (A),
- After printing a line, the printing section must be moved to the left end of the next line. On the other hand, with bidirectional printing as shown in Figure 1 (B), the printing section can be moved to the left or right end of the next line, whichever is closer, so it takes longer to move to the next line. can be minimized. Therefore, even if the moving speed of the printing section is the same, an efficient moving path of the printing section can be taken, so the average speed of printing is greatly improved when bidirectional printing is possible. This printing method is called bidirectional shortest printing.

In an innoguct type printer, the type is ink, ie
The moment when the ribbon is hitting the recording paper through the ribbon is for an extremely short period of time, and the rest of the time the ribbon is away from the recording paper, so the ribbon can be fed during that time.

Therefore, regardless of whether the printing section is moving left or right, bidirectional printing can be easily performed because the unused glue bottle portion can be fed out to the printing section by simply feeding the ribbon in one direction.

Because thermal serial printers don't use ink ribbons? There are no restrictions imposed by the printing process, and bidirectional printing can be easily achieved.

However, with conventional thermal transfer serial printers, bidirectional printing is difficult. This will be explained along with FIGS. 2 to S. There are two types of thermal transfer type serial gritters: as shown in Figure 2, the entire ink ribbon system moves together with the printing section, and as shown in Figure 3, the ink ribbon system does not move and only the printing section moves. be.

In FIGS. 21 and 3, 21 is a thermal head, 22 is a winding ribbon on the sending side, and 23 is a winding ribbon on the winding side.

First, we will explain the movement of the glue bottle in a thermal transfer type serial printer in which the entire ink ribbon moves together with the printing section as shown in FIG.

#¥ - During printing as shown in Figure (A), the thermal head moves in the direction of arrow 24 while constantly pressing the ink ribbon against the recording paper. Since the frictional force between the ribbon and the recording paper is much greater than the frictional force between the saw head, there is no slippage between the tape and the ribbon, but the head slides on the back side of the ribbon. Therefore, the ribbon is sent out from the feed side winding ribbon 22 by the frictional force from the recording paper, and is sent in the opposite direction (arrow 25) to the head movement at the same speed as the head movement, and then to the winding side winding ribbon 23. It is wound up.

Arrows 26 and 27 indicate the rotation direction of the delivery side ribbon and the take-up side ribbon during printing, respectively.

As shown in Figure 1 (A), forward printing is performed from left to right, and when the print reaches the right edge, when the head is released along with the recording paper and the rider from above, frictional force from the recording paper is applied to the bin. The ribbon is no longer fed out, and in this state, move the printing section in the direction of arrow 28 and return it to the left end (Fig. 2 (8)
reference). During this time, paper is fed in the vertical direction. Therefore, no printing is performed on the outward path.

On the other hand, in a thermal transfer printer in which the ink ribbon system does not move as shown in Fig. 3, the head moves in the direction of arrow 31 while pressing the ink ribbon onto the recording paper during forward printing, so the ribbon is not moved during this time. (See Figure 3 (^)).

In the writing path of the printing section, move the head away from the recording paper and move the unused glue back to the left end (arrow 320).
Container 2 that winds the used ink ribbon on the winding side while pulling it out from the winding ink ribbon 2 on the sending side (direction)
3 (see Figure 3 (B)). Therefore, in this case as well, printing cannot be performed because the head is separated from the recording paper on the forward path of printing.

Arrow 33 indicates the ribbon feeding direction, and arrows 34 and 35 indicate the rotating direction of the wound ribbon on the feeding side and the winding side, respectively.

In the method shown in Fig. 2, the movement K of the head during printing on the outward pass is affected, and in the method shown in Fig. 3, the movement of the head during the return pass is affected. is being sent. As explained above with reference to FIGS. 1 and 3, both systems have a configuration in which bidirectional printing cannot be performed.

Next, with reference to FIGS. 7 and 5, problems encountered when bidirectional printing is attempted in a thermal transfer type serial printer having such a conventional glue/pn running path will be pointed out.

Figure 2 shows the system in which the entire cylinder moves together with the printing part as shown in Figure 2, and Figure S shows the system in which the cylinder does not move as shown in Figure 3. This is a schematic drawing of the movement, IJ, and G feed.

1 is a recording paper, 21 is a thermal head, 22 is a winding pin on the sending side, 23 is a winding ribbon on the winding side, the scale on the recording paper l corresponds to the printed part on the recording paper, and the scale on the ribbon corresponds to the printed part. Hail ribbon. Recording paper! The upper hatched area represents the portion printed on the paper, and the front portion of the ribbon represents the used ribbon corresponding to the printed portion.

As shown in Figure 7, in the case of a method in which the entire ribbon moves together with the printing section, when the forward printing is completed and the printing section has reached the right end (see Figure 7 (A)), the length required for the return printing is determined. Feed the unused ink cartridges from left to right (see Figure B).
), you must start printing the outbound route.

For example, if the backward print is to be performed on scale marks 6 to 11 on the recording paper as shown in FIG. I have to keep it.

In the backward printing, the IJs 6 to 11, which were previously wound on the winding ribbon 23 on the winding side, are sent in the opposite direction to that in the forward printing. head t11

Outward printing must be started after the state shown in D) is established.

These ribbon feeds that occur at line breaks must be carried out at high speed, but thermal transfer ink ribbons are extremely thin and can easily break or become tangled, so it is difficult to create a mechanism that can feed them at high speeds. It involves many technical and cost difficulties.

In addition, the mechanism becomes complicated because the ribbon is fed in one direction during printing, and the ribbon needs to be fed while maintaining appropriate ribbon tension in either direction. arise.

On the other hand, when performing bidirectional printing with a method in which the ink ribbon system does not move, as in No. After feeding out the unused ink ribbon for the length necessary to print the row (see FIG. 3(B)), the return printing must be started. After the return printing is completed (see ggS diagram (C)),
Since the ribbon used for the backward printing is wound up (see Figure S (D)), the forward printing must begin. In this case, unlike the system in which the entire ink cartridge moves as shown in FIG. 11, the ribbon is fed in one direction, but at the time of line feed, it is still necessary to feed the pin at I'f+ speed.

As explained above, it is difficult for conventional thermal transfer serial printers to perform bidirectional printing due to the configuration of the paper running system.

OBJECTS OF THE INVENTION An object of the present invention, in view of the problems of the prior art as described above, is to provide an ink ribbon feeding method and device that enables back-and-forth printing in a thermal transfer type serial printer. .

Structure of the Invention According to the ink ribbon feeding method of the present invention, in a thermal transfer serial printer in which the entire ink ribbon moves together with the printing section, λ printing positions spaced apart in the feeding direction of the recording paper are set on the recording paper. The ink ribbon is moved from the ink ribbon feeding side so that the ink layer side of the ink ribbon faces the recording paper side at each of the λ printing positions such that the ink ribbon runs in opposite directions to each other in a direction crossing the feeding direction. An ink ribbon system is formed on the winding side, and one of the two printing positions is selected for each of the forward and backward printing paths.

The ink ribbon feeding device of the present invention is used in a thermal transfer serial printer in which the entire ink cartridge moves together with a printing section, and includes an ink ribbon delivery side winding means, an ink ribbon winding side winding means, and a recording paper feeding direction. Ink cartridges travel from the ink ribbon delivery side winding means to the ink ribbon take-up side winding means at a printing position spaced apart from each other in opposite directions in a direction crossing the feeding direction of the recording paper. an ink ribbon guide means for guiding the ink ribbon so that the ink ribbon can be guided so that the ink layer surface of the ink ribbon is on the recording paper at each of the λ print positions between the two printing positions and the ink ribbon guide means; 11! an ink ribbon folding means for folding the ink ribbon from the ink ribbon delivery side winding means to the ink ribbon take-up side winding means so as to face the ink ribbon; The present invention is characterized by comprising a selection means for selecting one of the two.

Basic Principle of the Invention First, the basic principle of the present invention will be explained with reference to FIGS.

The present invention makes it possible to perform bidirectional printing only by feeding the ribbon by head movement, by devising the ribbon running path, without having to feed the ribbon at high speed or in both directions.

FIG. 6(A) shows the movement of the ink cartridge system on the outward path during ink cartridge feeding according to the present invention, and FIG. 4(B)
shows the movement of the ink ribbon system on the outward path (Fig. 6 (
A) and (B) are views seen from the back side of the recording paper). The ink ribbon coming out from the supply side winding ribbon 67 is placed at λ printing positions 601 and 60 which are spaced apart in the feeding direction of the recording paper.
2, the ink ribbon can run in opposite directions in a direction that crosses the feeding direction of the recording paper, and is folded back so that the ink layer surface of the ink ribbon faces the recording paper side, and is on the winding side? is wound up on winding 66. Reference numeral 21 indicates a thermal head, arrows 62.degree. 63164 indicate the ink cartridge feeding direction, and arrows 65.degree.

This ink printing system, together with the thermal head, moves in the direction of arrow 68 on the outward path of printing;
9, and the entire ink ribbon system moves in the direction of arrow 6.
By moving up and down in the direction of 03, it is possible to select whether the thermal head is placed on the ribbon portion 601 or the 6ozK thermal head is placed on the ribbon portion. 601 is the upper recubin printing position, 6
02 Lower ribbon printing position fT.

7(A) and 7(BJ) schematically show the case where bidirectional printing is performed using the ink ribbon feeding method explained in connection with FIG. 6. Reference number 1 is a recording paper.
A) is forward printing, the thermal head is at the upper printing position, and the ribbon is pressed against the recording paper by the thermal head, so the ribbon moves in the direction of arrows 62, 63, and 64 at the same speed as the thermal head moves. is running on.

When the forward printing is finished and the printing section is at the right end, separate the thermal head from the recording paper, release the ink ribbon that was sandwiched between them, and raise the entire ink ribbon system so that the thermal head is at the printing position above the ribbon. Make it. During this time, the paper is fed in the direction of arrow 2.

Thereafter, the thermal head presses the ink ribbon against the recording paper to start backward printing (see FIG. 7(B)).

When the return printing is completed and the printing section returns to the left edge, remove the thermal head from the recording paper again, open the ink cartridge, and lower the entire ink ribbon running system so that the thermal head is at the printing position above the ribbon. do. Then, the thermal head is lowered again to start forward printing.

As can be seen from FIGS. 7(A) and 7(B), the ink ribbon travels in the same direction during the forward and return passes of printing, so as shown in the examples in FIGS. Bidirectional printing can be performed by simply feeding the ink ribbon using the movement of the thermal head, without having to feed the ink ribbon at high speeds or at high speeds.

Instead, a mechanism for moving the entire ink ribbon system up and down is required, but this can be realized relatively easily as will be explained later in the embodiment of the ink ribbon feeding device of the present invention.

There are problems with the folding of the ink ribbon, such as an increase in the number of bending points in the ink ribbon running system and an increase in running resistance, but these can also be solved by improving the folding method, guides, and rollers, as will be explained later in Examples. This can be solved by

Overall, the present invention has far fewer technical difficulties and problems than the method of feeding the ink ribbon in both directions or at high speed as shown in FIGS. 9 and 3.

As described above with reference to FIGS. 6 and 7, the feature of the present invention is that printing in the direction can be realized with a simple mechanism by adding some ingenuity to the running path of the ink ribbon.

Next, we will explain the consumption of ink cartridge in this method in the third section.
This will be explained in Figures (A) to (D). FIG. 3 is a view from the back side of the recording paper.

FIG. 3(A) shows the state when forward printing is completed, and the shaded area indicates the consumed portion of the ink ribbon.

The ink ribbon has been consumed up to a portion 601.

At the start of the next outward printing, the thermal head is activated as shown in Figure 3 (8).
As shown in 1, printing starts from the bottom printing position 602, but printing can be started from the unused part of the bottom.

The state in which the printing of the rolling path has been completed (see Figure 3 (C))
When attempting to move forward printing from , a used portion remains between the ribbon upper printing position 601 and the ink lower printing position 602 .

Therefore, so that the thermal head can start printing from the unused part of the ribbon, 601 to 6
Printing can be started after feeding the remaining used ribbon by moving the print unit while keeping the head pressed against the recording paper by an extra length d corresponding to 02 (see Figure 3 (D)). .

A specific example of this is shown in FIGS. 7(A) to (D). In Fig. 9, 1 is the recording paper, the solid line arrow XA from right to left is the return printing, the solid line arrow DY from left to right is the outward printing, and the dotted line arrow is the head for sending the remaining used ribbon. The part that moves while being pressed against the recording paper, A is the end position of backward printing, D is the start position of the next line of printing, B is the position where the head is released, and C is the position where the head is pressed.

When A and D are at almost the same vertical position as shown in FIG. 9(A), the ribbon is fed by moving between A and B while keeping the head pressed against the recording paper after completing the return printing.
At the 8th point, the head is released and the recording paper is fed in the vertical direction, and at the 0th point, the head is pressed again and moved between CO to continue feeding the used ribbon, and then from the 0th point, forward printing is started.

At this time, AB=CD and AB+CD=d may be satisfied.

As shown in FIG. 9(B), when point 0 is more than d away from point A, AB separates the head by keeping it at the minimum distance necessary to separate the ribbon.

At this time, A B+CD=d may be satisfied.

As shown in FIG. 9(C), when the 0 point is more than d to the left of the A point, AB==d.

If the return print is followed by the return print as shown in Fig. 9 (0), then what happens? There is no need to send the rest of the used ribbon because the printer moves on to printing the next line without moving the ribbon running system up or down. Therefore, after moving the minimum distance AB necessary to separate the recan, the head is released, the printing section is moved to the 0 point, and printing of the next line is immediately started.

Embodiment of Apparatus Next, an embodiment of the ink ribbon feeding apparatus of the present invention based on the above-described principle will be described with reference to FIGS. 1.theta. to 1g.

FIG. 70 schematically shows an embodiment of the ink ribbon feeding device according to the present invention, and this embodiment has a diameter of 4.5 mm with respect to the running direction of the ink ribbon. A roller 101 with a rotation axis of

Flip O degree and position 601, 6 on the ribbon where the head hits
In 02, the same ink surface falls in the direction of the recording paper,
It was designed to run in opposite directions.

Is 66 winding on the winding side? The numeral 67 is a delivery bong for winding 9111 winds. The rollers 101 and 102 are slightly recessed at the +7 and y portions to prevent the ribbon from shifting. The guide roller 100 has λ printing positions [601
and 602, the side winding ribbon 6 is fed out by the ink ribbon in opposite directions to each other in a direction crossing the feeding direction of the recording paper.
An ink ribbon guiding means is constituted for guiding the ink ribbon from 7 to 5 so that it can travel to the winding side winding ribbon 66.

Figure 1/Figure bends the ribbon in the same way as Figure 10, but
This is an example in which a guide plate 111 is used instead of a roller.

FIG. 12 shows the lithine twisted and folded back by rollers 121. Is the ribbon coming out of the feeding side winding ribbon 67 at the ribbon lower printing position F? After passing 602, it is twisted 90 degrees in the counter-time opening direction toward the running direction and becomes low 7.
Enter -121.

After being turned back by 1gO degrees at 121, it is twisted clockwise by 9θ degrees and passes through guide rollers 122 to form upper printing section tank 601.
The ribbon passes through and is wound onto the winding side ribbon 66. Therefore, the upper and lower ribbons have their ink surfaces facing toward the recording paper and run in opposite directions.

124 is a mounting table on which the entire ribbon running system is placed;
By moving this up and down, it is possible to select whether the upper part or the lower part comes to the head position.

The reason why the lower ribbon protrudes forward by 2 points than the upper ribbon in Figures 1 and 72 is to prevent the lower part of the head from coming into contact with the lower ribbon when the upper ribbon has a head. If it is acceptable for the ribbon to rub against the lower part of the head, or if a head 132 with a protruding heating element part is used as shown in FIG. 73, 2=01, that is, the upper and lower bins may be on the same plane.

FIG. 11 is an example of a selection mechanism for moving the ribbon system up and down in the case shown in FIG. 72. 141 is a platen, and 21 is a head.

FIG. 11I (A) shows when forward printing is being performed, and the upper ribbon is at the position of the head. Figure (B) does not show the state in which the lower ribbon is at the head position during forward printing.

The mounting table 124 on which the bottle system is placed selects the upper and lower printing positions by moving in an arc at an angle θ about point P. If this is done, it is a fairly simple mechanism, and the upper and lower positions of the bottle system can be selected. is possible.

To strictly maintain the parallelism of the head and bottle during printing, do as shown in the first diagram on the left.

151 moves horizontally with the head but is fixed vertically.

The links QR and ST are links that move in an arc around points Q and S, respectively, and the entire ribbon system moves in parallel in an arc, so the parallelism between the head and the ribbon is always maintained.

Figure 76 shows the angle θ between the upper daily bottle and the lower ribbon.
By adding , the heads and the bins are made parallel during printing even if the ribbon traveling system is moved up and down in an arcuate motion within the range of angle θ.

FIG. 77 shows the top and bottom of the ribbon system in this case. P is the center point of the arc motion.

The angle formed by the upper and lower ribbons is the angle θ of the circular arc motion of the gun system.
By making it the same, the ribbon and head can be made parallel in both forward and outward printing.

Next, the case of using a thermal transfer ink ribbon that can be used several times will be explained using FIG. 7g.

(Figure 1g is a view from the back side of the recording paper.) Since the ribbon feed direction is always in one direction, the entresive ribbon shown in Figure 1g (both ends are connected to form a ring)
can be used.

If the endless ribbon is long, it is stored with slack in the portion shown at 180.

Rollers 181 and 182 sandwich the endless ribbon,
It rotates at the same peripheral speed as the head movement speed. Therefore, the endless ribbon circulates in the direction of arrow 183 at the same speed as the head movement speed.

That is, it is pulled out from the supply side exit 184, passes through the lower printing position 602, is turned back at the 1850 part, passes through the upper printing position 601, is collected through rollers 181 and 182, follows the storage part 180, and returns to the supply side exit 184. appear. The reason why the endless ink ribbon is twisted by 7 g and 0 degrees around the direction of travel at the part 186 is to correspond to the folded part 185 so that the ink layer surface of the endless ribbon faces the recording paper side at each of the upper and lower printing positions. This is for the purpose of

In the case of this endless ribbon, Fig. 6 to Fig. g, M/
It is considered that the take-up side winding ring 66 and the delivery side winding groove 767 in Figures θ to 72 and FIG. 16 are replaced with a continuous ring. Follow me? The vertical mechanism of the running system is the same as that explained in FIGS. 7q to 77.

Effects of the Invention Since the ink ribbon feeding method and device of the present invention are based on the above-mentioned principle, even in thermal transfer serial printers, it can be used in both directions with a relatively simple mechanism without losing the reliability of the ribbon feeding system. The shortest possible printing speed can be achieved, and printing speeds can be significantly improved.
