The control means 87 controls the movement of the printing material 13 positioned in front of the thermal ribbon 45 by controlling the movement of the moving rollers 77 and 79 of the moving mechanism 15.

FIG. 5 shows a first example in which the manufacturing date is printed on the substrate 13 using the above-described thermal printer.
In this example, the width W of the printing material 13 is increased to, for example, about 500 mm, and four packing parts 13a, 13b, 13c, and 13d are formed on the printing material 13 at intervals in the width W direction. Yes.

The date of manufacture is printed on the printing unit 13e in the direction perpendicular to the width W direction of the four packing units 13a, 13b, 13c, and 13d.
This printing is performed by sequentially moving the head unit 21 along the slide rail 17 with the substrate 13 stopped in front of the thermal ribbon 45.

That is, in this example, the packing portions 13a, 13b, 13c, and 13d are formed in one stage in the feeding direction of the printing material 13 between the registration marks 13R of the printing material 13, and correspond to the interval L0 of the registration marks 13R. The substrate 13 is sent intermittently by the length.
Then, when the printing material 13 is stopped in front of the thermal ribbon 45 and the printing material 13 is not fed, printing is performed on the one-stage packing portions 13a, 13b, 13c, and 13d positioned between the registration marks 13R. .

  That is, first, the head unit 21 is moved to the position of the first packing part 13a on the left side of FIG. 5 by rapid feed, and the date of manufacture is printed on the first packing part 13a. Next, the head unit 21 is moved to the position of the second packing part 13b adjacent to the first packing part 13a by fast-forwarding, and the date of manufacture is printed on the second packing part 13b. Similarly, printing on the third packing part 13c and the fourth packing part 13d is performed.

Then, after a series of printing is performed on the packing portions 13a, 13b, 13c, and 13d in the width W direction of the substrate 13 in this way, the head unit 21 is moved to the base position.
Further, after printing, the substrate 13 is intermittently sent by a length corresponding to the interval L0 of the registration mark 13R, and new packaging portions 13a, 13b, 13c, 13d of the substrate 13 are supplied in front of the thermal ribbon 45. Is done.
In the same manner, printing on the new packing portions 13a, 13b, 13c, and 13d of the substrate 13 is performed.

  FIG. 6 shows a method of feeding the thermal ribbon 45 in the first example. The feeding of the thermal ribbon 45 is performed by using the ribbon short dimension feeding mode and the ribbon long dimension feeding mode which the control means 87 has.

First, as shown in FIG. 6 (a), with the thermal ribbon 45 stopped, printing is performed at intervals in four locations in the width direction of the substrate 13 so that the thermal ribbon 45 is spaced and unused. Part M is formed.
Next, as shown in FIG. 6B, in order to use the unused portion M, the ribbon feeding mechanism 47 is controlled by the ribbon short feed mode, and the thermal ribbon 45 is fed by one pitch.

Then, in a state where the thermal ribbon 45 is stopped at this position, printing is performed at intervals at four locations in the width direction of the substrate 13.
Next, as shown in FIG. 6C, in order to use the unused portion M, the thermal ribbon 45 is fed by one pitch.
Then, in a state where the thermal ribbon 45 is stopped at this position, printing is performed at intervals at four locations in the width direction of the substrate 13.

Next, as shown in FIG. 6D, in order to use the unused portion M, the thermal ribbon 45 is fed by one pitch.
Then, in a state where the thermal ribbon 45 is stopped at this position, printing is performed at intervals at four locations in the width direction of the substrate 13.
In this state, all unused portions M of the thermal ribbon 45 are used.

Therefore, as shown in FIG. 6E, the ribbon feeding mechanism 47 is controlled by the ribbon long-distance feeding mode, and the used portions of the thermal ribbon 45 are fed together.
Then, as shown in FIG. 6 (f), with the thermal ribbon 45 stopped, printing is performed at intervals in four locations in the width direction of the printing material 13 so that the thermal ribbon 45 is spaced and unused. Part M is formed.

Thereafter, the thermal ribbon 45 is used by repeating the above-described operation.
In the thermal printer described above, the slide rail 17 is arranged in the width direction of the substrate 13 to be supplied, the head unit 21 is moved along the slide rail 17, and the thermal head 19 of the head unit 21 is moved at a predetermined position. Since the printing object 13 is pressed through the thermal ribbon 45 to be printed at intervals in a plurality of positions in the width direction of the printing object 13, the width direction of the printing object 13 is also large. Can be printed quickly and reliably at intervals.

  Further, in the above-described thermal printer, the unused portion M formed at intervals on the thermal ribbon 45 is used in the ribbon short-size feed mode, and the unused portion M is used in the ribbon long-size feed mode after the unused portion M is used. Since the used parts of the ribbon 45 are sent together, the thermal ribbon 45 can be used effectively even when printing is performed at intervals in a plurality of positions in the width direction of the substrate 13.

  FIG. 7 shows a second example in which the date of manufacture is printed on the substrate 13 using the above-described thermal printer. In this example, the packing parts 13a, 13b, 13c, Printing on 13d is performed on the printing unit 13f formed in the width W direction of the substrate 13.

FIG. 8 shows a third example in which the manufacturing date is printed on the substrate 13 using the above-described thermal printer.
In this example, two stages of printing are performed between the registration marks 13R of the substrate 13.
In other words, in this example, the packing portions 13a, 13b, 13c, and 13d are formed in two stages in the feeding direction of the printing material 13 between the registration marks 13R of the printing material 13, and the length corresponding to the interval L1 of the registration marks 13R. Thus, the substrate 13 is intermittently sent.

Then, when the substrate 13 is stopped in front of the thermal ribbon 45 and the substrate 13 is not fed, printing is performed on the two-stage packing portions 13a, 13b, 13c, and 13d positioned between the registration marks 13R. .
In this example, first, as shown in FIG. 8A, printing is performed on the upper packing portions 13a, 13b, 13c, and 13d between the registration marks 13R of the substrate 13 to be printed.

Next, as shown in FIG. 8B, printing is performed on the lower packaging portions 13a, 13b, 13c, and 13d between the registration marks 13R of the substrate 13 to be printed.
At the time of this printing, the pair of moving rollers 77 and 79 of the moving mechanism 15 shown in FIG. 2 are moved downward by the control means 87, and the substrate 13 is moved to the position moved upward by the length L. The

That is, the substrate 13 is moved at the time of non-feeding, and the position of the registration mark 13R of the substrate 13 is stopped at the position moved upward by the length L, and the position of the substrate 13 with respect to the thermal ribbon 45 is changed. The
In this state, printing is performed on the lower packaging portions 13a, 13b, 13c, and 13d between the registration marks 13R of the substrate 13.

  In this example, when the substrate 13 that is intermittently fed is not fed, the control unit 87 controls the moving mechanism 15 to move the substrate 13 to change the position of the substrate 13 relative to the thermal ribbon 45. Thus, the printing position with respect to the printing material 13 can be easily and reliably changed without moving the heavy thermal printer 11.

  In addition, since the substrate 13 is moved once with respect to one intermittent feed of the substrate 13 and printing is performed in two stages in the feed direction of the substrate 13 fed by one intermittent feed. Further, it is possible to increase the number of print locations for one intermittent feed of the substrate 13.

  In this example, the example in which the substrate 13 is moved once for one intermittent feed of the substrate 13 has been described. However, the substrate 13 is moved for one intermittent feed of the substrate 13. You may move multiple times.

FIG. 9 shows a fourth example in which the manufacturing date is printed on the substrate 13 using the above-described thermal printer.
In this example, the thermal ribbon 45 has, for example, a width W1 of about 60 mm, and the upper, middle, and lower stages in the width direction of the thermal ribbon 45 are used for printing, so that the thermal ribbon 45 can be saved. Yes.
That is, in this example, first, as shown in FIG. 9A, printing on the printing material 13 is performed using the lower part of the thermal ribbon 45 in the width direction.

Printing using the lower part of the thermal ribbon 45 in the width direction is performed without moving the substrate 13 sent by intermittent feeding by the moving mechanism 15.
Next, when the substrate 13 is moved intermittently, the intermediate portion of the thermal ribbon 45 in the width direction is used as shown in FIG. Printing on the printed material 13 is performed.

At the time of this printing, the pair of moving rollers 77 and 79 of the moving mechanism 15 shown in FIG. 2 is moved downward by the control means 87, and the substrate 13 has a length corresponding to the width W2 between the lower and middle stages. Stopped at the position moved upward.
That is, the substrate 13 is moved at the time of non-feeding, and the position of the registration mark 13R of the substrate 13 is stopped at a position moved upward by a length corresponding to the width W2, and the substrate 13 with respect to the thermal ribbon 45 is stopped. The position is changed.

In this state, printing on the printing material 13 is performed using the middle part of the thermal ribbon 45 in the width direction.
Next, when the printing material 13 is moved intermittently, the printing material 13 is not used by feeding the thermal ribbon 45 and using the upper part in the width direction of the thermal ribbon 45 as shown in FIG. Printing is performed.

At the time of this printing, the pair of moving rollers 77 and 79 shown in FIG. 2 are moved downward by the control means 87, and the substrate 13 is further moved from the state (b) to the width W3 between the middle and upper stages. It stops at the position moved upward by the corresponding length.
That is, the substrate 13 is moved during non-feeding, and the position of the registration mark 13R on the substrate 13 is stopped at a position where the registration mark 13R is moved upward by the length of the width W2 plus the width W3. The position of the printed material 13 is changed.

In this state, printing on the printing material 13 is performed using the upper stage of the thermal ribbon 45 in the width direction.
In this example, when the substrate 13 is not fed, the substrate 13 is moved and printing is performed by changing the position in the width direction of the thermal ribbon 45. Therefore, the thermal ribbon 45 can be used effectively. it can.

In other words, in this example, printing can be performed using the upper, middle, and lower stages in the width direction of the thermal ribbon 45, so that the thermal ribbon 45 can be effectively used.
Further, in printing using the lower stage of the thermal ribbon 45, for example, the printing part at the lower part of the thermal head 19 is used. In printing using the upper stage of the ribbon 45, for example, the print portion on the upper part of the thermal head 19 is used, and the position of the print portion of the thermal head 19 used is different, so that the life of the thermal head 19 is increased. Can do.

  In this example, the example in which the width direction of the thermal ribbon 45 is divided into three stages has been described. For example, the thermal ribbon 45 may be divided into two stages, or may be divided into four or more stages. Also good.

Further, in this example, the thermal ribbon 45 can be fed using the ribbon short dimension feed mode and the ribbon long dimension feed mode as shown in FIG.
In this case, as shown in FIG. 9C, the thermal ribbon 45 is stopped until there is no unused portion in the width direction of the thermal ribbon 45.
Then, after there is no unused portion in the width direction of the thermal ribbon 45, the thermal ribbon 45 is fed by the ribbon short-distance feed mode, and the unused portion M formed at intervals on the thermal ribbon 45 is used.

And after using all the unused parts of the thermal ribbon 45, the used part of the thermal ribbon 45 is collectively sent by ribbon long dimension feed mode.
Further, in each of the above-described printing examples, the example in which printing is performed by moving the substrate 13 upward from the intermittently fed position is described, but if necessary, the substrate 13 is moved downward from the intermittently fed position. You may move to and print.

Further, in the above-described embodiment, an example in which one head unit 21 is arranged on the slide rail 17 has been described. However, the present invention is not limited to such an embodiment, and for example, a plurality of heads are provided on the slide rail 17. The unit 21 may be arranged.
Further, in the third printing example described above, the substrate 13 is moved with respect to one intermittent feed of the substrate 13, and a plurality of stages are provided in the feed direction of the substrate 13 sent by one intermittent feed. In the fourth printing example, the example in which printing is performed by moving the printing object 13 and changing the position of the thermal ribbon 45 in the width direction has been described in the fourth printing example. The control unit may be controlled to perform printing so that the third printing example and the fourth printing example are performed simultaneously.

  Furthermore, in each printing example mentioned above, although the example which intermittently sent the to-be-printed material 13 was described, this invention is not limited to this example, By controlling the moving mechanism 15, the to-be-printed material 13 is made. The present invention can also be applied in the case of continuous supply.
