Description

The present invention relates to a receipt issuing device used in a product sales registration device such as an electronic cash register.

[Prior Art] Conventionally, for example, roll paper is set in an electronic cash register, and when sales data of a product purchased by a customer is registered, the sales registration data is printed by the printer while feeding the roll paper, When the registration of the sales data is completed and the registration operation is closed, the printer prints the total of the customers or the roll paper is cut by a cutter and a receipt is issued. In addition, the roll thickness of the roll paper is detected by a sensor, and when the roll thickness becomes thin near the core, it detects that there is no paper and cuts the paper to stop the printing operation of the printer and replace the roll paper with a new one. There is. Then, the stop control of the printing operation is performed at that time when the absence of paper is detected even when the printing of all sales data of a series of products purchased by the customer is not completed.

[Problems to be Solved by the Invention] However, as described above, even when the sales data of the customer's product is being printed, if a paper empty is detected, the paper is cut and printing is stopped at that point. There is a problem that when the paper is exchanged with another one, the remaining sales data is printed on the paper and the receipt is handed to the customer in a form separated into two sheets.

Therefore, according to the first aspect of the present invention, even if a paper absence is detected during printing of a customer's sales registration data, all the remaining sales registration data of the customer is printed and a receipt is issued, and then printing stop control can be performed. It is an object of the present invention to provide a receipt issuing device that can always hand one receipt to a customer even when paper is exhausted.

Further, since the leading end of a new roll paper is not cut cleanly, conventionally, when a new roll paper is set, it is troublesome to perform some operation of feeding and cutting the roll paper.

Therefore, a second aspect of the present invention is to provide a receipt issuing device that can automatically feed and cut a new roll paper when a new roll paper is set, and can easily replace the paper.

[Means for Solving Problems] A first aspect of the present invention is to issue a receipt for printing customer sales registration data in sequence while feeding roll paper with a printer, and cutting the paper with a cutter when printing is finished to issue a receipt. In the device, a sensor for detecting the paper empty state of the roll paper, a detection unit for detecting whether or not the customer's sales registration data is printed, and a detection unit for detecting the paper empty state when the sensor detects the paper empty state When not detected, the remaining sales registration data is printed, a receipt is issued, and then the printer print stop control is performed. When the detection means detects the print end, the printer print stop control control means is provided immediately. It is a thing.

Further, the second invention further comprises an automatic paper cutting means for feeding the roll paper by a predetermined amount and driving the cutter to cut the paper when the paper non-detection state is released after the sensor once detects the paper no-state. It is a thing.

[Operation] In the first invention having such a configuration, when the sensor detects that the roll paper is out of paper, the detection means detects whether or not the customer's sales registration data has been printed, and the printing is completed. If not, the remaining registered sales data is printed on the roll paper by the printer, the receipt is cut, and then the printing operation of the printer is stopped and controlled. When the roll paper is replaced with a new one in this state, the sensor no-paper detection state is released, and the roll paper is automatically fed by a predetermined amount and cut by the cutter.

Embodiments Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, the invention is applied to a single electronic cash register.

FIG. 1 is a perspective view showing the external appearance of an electronic cash register. 1 is an operation unit provided with keys for registering product sales data, 2 is a display unit for displaying registration data, and 3
Is a storage unit in which the receipt issuing device is stored, 4 is a receipt issuing port for taking out the receipt issued by the receipt issuing device to the outside, and 5 is a drawer.

FIG. 2 shows a schematic structure of a mechanical section of the receipt issuing device stored in the storage section 3. Roll paper 11 is set in the storage section 3, and the roll paper 11 is used in a stamp printing machine.
12, it is sent to the receipt issuing port 4 via the printer 13 and the cutter 14.

The stamp printer 12 stamps a message such as "Thank you every time." On the paper, and the printer 13 prints the sales registration data of the product on the paper.

The roll paper 11 is provided with a micro switch 15 as a sensor that detects the winding thickness of the roll and turns on and off.

FIG. 3 is a block diagram showing a circuit configuration. 21 is a CPU that constitutes the main body of the control unit, 22 is a ROM in which program data for the CPU 21 to control each unit is stored, and 23 is registered as shown in FIG. RAM with memory 23a, print buffer 23b, display buffer 23c, printing flag 23d, no paper flag 23c, etc.
Is. Further, 24 is an operation unit controller for taking in and controlling key signals and the like from the operation unit 1, 25 is a display unit controller for controlling output of display data to the display unit 2, and 27 is for controlling the printer 13 to print data. Along with the operation to close the customer registration with the operation unit 1, the CP
A printer / drawer controller that controls the drawer opening device 26 in response to a command from U21. Further, 28 is an I / I for input-processing the switch operation signal of the micro switch 15.
An O port, 30 is an I / O port for outputting a drive signal to the buzzer 29.

The CPU 21 is electrically connected to the ROM 22, RAM 23, each controller 25, 27, 28 and each I / O port 28, 30 via a bus line 31.

The CPU 21 constitutes a part of the receipt issuing device together with the printer 13 and the printer / drawer controller 27, and performs print control without paper as shown in FIG. That is, the sales registration data registered in the registration memory 23a is edited into print data and stored in the print buffer 23b. If the data is the customer's first sales registration data, the printing flag 23d is set.

Next, the printer 13 prints the data in the print buffer 23b on the roll paper 11. Then, the switch operation signal of the micro switch 15 is read to check whether or not there is paper. If there is no paper, then the no-paper flag 23e
Check whether or not is set, and the paper empty flag 23
If e is not set, the print data is stored again in the print buffer 23b and printing is performed.

During such printing operation, the micro switch 15
Detects that there is no paper, the buzzer 29 is operated via the I / O port 30. To stop the operation of this buzzer, for example, the clear key is operated on the operation unit 1.

Then, the no-paper flag 23e is set. Then, it is checked whether or not the printing flag 23d is set. If the customer's sales registration data remains unprinted, the print flag 23d is set.At this time, the printer 13 is driven while sequentially setting the remaining data in the print buffer 23b, and the data is transferred to the roll paper 11. Print it. When the registration is closed in the operation unit 1 and the total data is set and printed in the print buffer 23b and the print data is the last print data, the printing flag 23d is reset and the printer 13 is controlled to stop printing.

When the roll paper 11 is replaced with a new one, the switch operation signal from the micro switch 15 is first read.
Then, when the replacement is performed, since there is paper, it is subsequently checked whether or not the paper-free flag 23e is set. When the roll paper is exchanged without paper, the paper no flag 23e is set. Therefore, the paper no flag 23e is reset, the roll paper 11 is fed for five lines, and the cutter 14 cuts the paper to align the leading ends.

In the present embodiment having such a configuration, when the registration operation of the products purchased by the customer is sequentially performed on the operation unit 1, the sales data is sequentially registered in the registration memory 23a. Then, the sales registration data at this time is displayed on the display unit 2 via the display buffer 23c, and
The printer 13 sequentially prints on the roll paper 11 via 23b.

When the micro switch 15 detects that the roll paper 11 is empty during the product registration process as described above, the buzzer 29 operates to notify the operator and the operation unit 1 closes the customer registration. Printing of sales registration data is continued until. When the operation for closing the customer registration is performed in the operation unit, the total number of customers is printed on the roll paper 11 by the printer 13 via the print buffer 23b, the paper 11 is fed and cut by the cutter 14, and the receipt is issued. Be seen. When the receipt is issued, the printing operation of the printer 13 is controlled to stop. Therefore, after that, the printing of the sales registration data is prohibited.

When the operator replaces the roll paper with a new one in this state, the micro switch 15 detects the paper present state, and the paper non-existence flag 23e is set. After being fed for five lines, the cutter 14 cuts the ends to align them. In this way, the print stop state of the printer 13 is released, and the next customer waits for product registration.

When the roll paper 11 is detected to be empty during the customer product registration in this way, the sales registration data is validly printed on the paper until the registration is completed for that customer. When the final printing is completed, the cutter 14 cuts the paper to issue a receipt and then controls the printing stop. Therefore, the receipt to be delivered to the customer is not divided into two and is always one. Therefore, there is no risk of complaints from customers.

Further, when the roll paper 11 is replaced with a new roll paper, the paper is automatically fed by five lines and cut by the cutter 14 so that the leading ends are aligned, so that the conventional operation for aligning the leading ends is not necessary. Exchange work becomes easy.

It should be noted that the above-mentioned embodiment has been described by applying the present invention to a single electronic cash register, but the present invention is not necessarily limited to this, and is also applicable to a type in which a printer device and a data processing unit are separated. It is possible.

Further, in the above-mentioned embodiment, the one using the microswitch as the sensor is described, but the invention is not necessarily limited to this. For example, a mark is preliminarily attached to a sheet, and it is detected by an optical sensor or a magnetic sensor. Of course, various modifications are possible.

[Effects of the Invention] As described in detail above, according to the first aspect of the invention, even if a paper empty is detected during printing of a customer's sales registration data, all of the customer's remaining sales registration data is also printed and a receipt is printed. It is possible to provide a receipt issuing apparatus that can control printing stop after issuing, and therefore can always hand one receipt to a customer even if paper is lost.

According to the second aspect of the invention, when a new roll paper is set, the roll paper can be automatically fed and cut, and a receipt issuing device can be provided which simplifies the paper replacement work.
