It is the figure which showed the case where 1 line part of this print image for receipts was latched.
[0051]
By executing the receipt / journal printing process as described above, the receipt and the journal shown in FIG. 10A can be divided and printed simultaneously in one system of thermal printer. At this time, since the print item of the receipt is different from the print item of the journal, when the receipt / journal print process is executed by the single receipt printer, the blank of the journal increases. However, as shown in FIG. 10B, the same print data is enlarged in the vertical direction and printed in a predetermined print area of the journal, so that a blank can be filled. For example, in the case of the receipt shown in FIG. 9, since the receipt is 14 lines and the journal is 9 lines, the print on the journal side is enlarged 14/9 = 1.555, that is, about 1.6 times in the vertical direction.

[0052]
As described above, the ECR 10 according to the first embodiment of the present invention has a function of enlarging the print on the journal side in the vertical direction in accordance with the number of print lines on the receipt side, so that unnecessary blank space is left in the journal. Without making it, you can use the printed sheet effectively. Further, as the same transaction content, journal printing with uniform line width is possible. Furthermore, since the size of the character is different for each transaction content, when looking at a series of journal prints, the separation for each transaction becomes clear. In addition, for example, by having a function to enlarge only the important information on the journal side in the vertical direction according to the number of print lines on the receipt side, it is easy to describe the position and amount of important information when looking at a series of journal prints. Can be recognized.

[0071]
In the above-described embodiment, the printing mechanism that prints the receipt and the journal at the same time is not specifically shown. For example, a printing mechanism and a spool mechanism as shown in FIG. 16 can be used.
[0072]
FIG. 16 is a plan view mainly showing the drive mechanism of the thermal head portion in the thermal printer mounted on the case and the drive mechanism of the spool. FIG. 16 shows a case where the receipt roll paper 17a is set on the left side of the figure and the journal roll paper 17b is set on the right side thereof.
[0073]
In FIG. 16, reference numeral 71 denotes a thermal head for printing on the receipt roll paper 17a, and 17h denotes a thermal head for printing on the journal roll paper 17b. Each of the thermal heads 17g and 17h has a printing surface fixed to a driving end portion of a plunger driven in two sets of solenoids (not shown), and a receipt roll paper 17a conveyed on the rubber roller 17j. And at the time of each printing on the journal roll paper 17b, the corresponding solenoid is driven, and each printing surface is pressed against each roll paper surface. When the drive for the solenoid is released, the plunger is returned to the non-drive position by the action of a return spring provided in each solenoid, and the thermal heads 17g and 17h are returned to the print standby position.
[0074]
Therefore, by performing printing control to print the receipt roll paper 17a and the journal roll paper 17b when they are pressed against the rubber roller 17j by the thermal heads 17g and 17h, two roll papers are provided by one rubber roller 17j. It becomes possible to control the conveyance of each of them separately. FIG. 16 shows a case where the thermal head 17g is pressed by the comb roller 17j and is in the printing position, and the thermal head 17h is in the printing standby position.

Further, in FIG. 16, a spool 17f has a pressing plate 17c attached according to the paper width of the journal roll paper 17a, and is rotated by a winder motor 17d. The spool 17f is driven to rotate when the journal roll paper 17a for which journal printing has been completed is taken up.
[0077]
Therefore, the ECR 10 has a receipt print thermal head 17g and a journal print thermal head 17h for the receipt roll paper 17a and the journal roll paper 17b conveyed by a single roll paper conveyance mechanism. Since the thermal head drive mechanism capable of independently controlling printing is installed, it is possible to efficiently use the receipt roll paper 17a and the journal roll paper 17b that are printed simultaneously during the transaction.
[0078]
In the ECR 10 of the above embodiment, the receipt roll paper 17a is set on the left side, the journal roll paper 17b is set on the right side, and the end sensor for detecting the receipt roll paper 17a is attached to the sensor mounting plate. The roll paper setting position is not limited to this. When the roll paper setting position is reversed, a near-end sensor for detecting the journal roll paper 17b may be attached to the sensor mounting plate. .

Next, FIG. 17 is an enlarged cross-sectional view of a roll paper feed section. As shown in FIG. 6A, the roll paper feed section is composed of the rubber roller 17j and the paper holder attachment 17n shown in FIG. The paper holder attachment 17n is a bristle that is aligned in a certain direction, and applies a certain pressure to the roll paper to send it to the paper feed port of the rubber roller 17j and hold it.
[0080]
Thereby, it is possible to prevent the roll paper from being detached from the rubber roller 17j due to reverse feed of the printing device 17 or the like. Further, as shown in FIG. 5B, even when the roll paper is removed from the rubber roller 17j, the roll paper can be held in the forward rotation direction of the rubber roller 17j. Furthermore, the roll paper can be smoothly inserted into the rubber roller 17j.
