Abstract

PURPOSE:To enable printing of a slip to be continued by a simple operation even though printing operation is interrupted by detection for no paper with a slip sensor in printing operation by a method wherein slip paper is set under a state in which a printing data of one sheet content of slip paper is stored in a slip buffer. CONSTITUTION:When a printing data for a credit slip is generated by input of a data from a keyboard 5, a host computer 8, and a card reader 16, the printing data of said credit slip one sheet content is prepared to be stored in a slip buffer 31. When the credit slip is correctly set in a slip insertion opening 24 of a slip printer 10, the printing data in the slip buffer 31 is successively read out to a printing buffer 33 by one line unit. A printing mechanism 11 and a paper feed mechanism are operated each time, and a content in the printing buffer 33 is outputted by printing to the credit slip. At that time a number of printed lines on the credit slip is counted with a printed line number counter (n).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slip printing device that prints on a sheet of slip paper.

[Prior Art] Generally, this type of slip printing device is equipped with a slip sensor for detecting the presence or absence of a slip. The printer is configured to control the printing operation to stop when the slip paper is removed from the detection position of the sensor and the output of the sensor changes to an output of no paper. In this case, since the print data is stored in the memory, the solution is to set a new slip form in the device and start printing again from the beginning.

[Problems to be Solved by the Invention] In this way, in the past, for example, if the slip paper was set at an angle and the slip sensor detected that there was no paper during the printing operation and the printing operation was stopped, the The slip paper had to be discarded, a new slip paper was used, and the printing operation had to be restarted from the beginning, which not only wasted the paper but also took time to reprint.

Therefore, the present invention provides a solution that even if the slip sensor detects that there is no paper during the printing operation and the printing operation is interrupted,
To provide a slip printing device which can continue printing a slip from an interrupted position by using the slip paper in the middle of printing with a simple operation, and can prevent waste of paper and printing time.

Means for Solving Problem C3 The present invention includes a slip buffer that stores print data for one slip sheet, a slip sensor that detects the presence or absence of a slip sheet,
A slip printing means for sequentially reading the print data in the slip core in response to the paper presence output of the sensor and printing it on the slip paper, and a line number counting means for counting the number of lines printed on the slip paper by this printing means. and an interruption control means for interrupting the printing operation if there is an output of no paper from the slip sensor during the printing operation of the printing means, and an interruption control means for interrupting the printing operation when there is an output of paper from the slip sensor while the printing operation is interrupted by the interruption control means. and a restart control means for restarting the printing operation by the printing means from the interrupted position after blankly feeding the slip paper based on the count value by the line number counting means.

"Function" In the slip printing device with such a configuration, the slip paper 1
When a slip paper is set with the print data for each sheet stored in the slip buffer, the print data in the slip buffer is sequentially read out in response to the paper presence output of the slip sensor.
Printed out on slip paper. At this time, the number of lines printed on the slip is counted by the line number counting means. During this printing operation, if the slip sensor outputs no paper because the slip paper is set tilted, for example, the printing operation is interrupted at that point. Therefore, when the slip paper that is in the middle of printing is reset, the reset slip paper is skip-fed based on the count value by the line number counting means, and then the printing operation is resumed from the interrupted position. the result,
Even if the printing operation is interrupted due to a paper out output from the paper sensor during the printing operation, the printing operation can be continued in a short time by using the slip paper that is being printed as is.

[Embodiment] Hereinafter, an embodiment in which the present invention is applied to a credit slip printing device will be described with reference to the drawings.

FIG. 1 is a block diagram of a credit slip printing device. In the figure, 1 is a CPU constituting the main body of the control unit, and this C'PUI is connected to an RO for storing fixed data such as program data via a pass line 2.

A keyboard/display controller 7 that controls each of the displays 6, a communication interface 9 that sends and receives data to and from a host computer 8 installed at a credit card issuing company as a host model, and prints on a sheet-like credit slip. pickpocket printer 10
a printer controller 13 that drives and controls the printing mechanism 11 and paper feed mechanism 12, respectively; an I10 port 15 that receives signals from the slip sensor 14 provided in the slip printer 10; and a card reader 16 that reads credit card data. I where the data signal is input
10 boats 17 etc. are connected to each other.

Here, in the RAM 4, as shown in FIG.
A slip buffer 31 for storing print data for one credit slip, an area 32 of a read pointer p for this slip/sofa 31, and the slip printer 10.
Print buffer 3 that temporarily stores print data output to
3. A print line number counter n area 34 for counting the number of lines printed by the slip printer 10 is provided.

FIG. 2 is an external perspective view of the slip printer 10, in which a slip table is provided at the front of the casing 21, and a printer cup is provided at the rear of the front. Further, a slip insertion opening 24 is formed in the gap between the slip table 22 and the printer cover 23, and a guide member 25 is attached to one side of the slip insertion opening 24. Thus, the credit slip 26 is set on the slip table 22 by inserting its tip into the slip insertion slot 24 with one side of the credit slip in contact with the guide member 25. As a means for detecting the set state of the credit slip 26, for example, the optical slip sensor 14 is provided.

There is printing on the inside of the printer cover 23.

The printing mechanism 11 such as an ink ribbon, and the paper feeding mechanism 12 such as a step/sopping motor and a feed roller are housed.

When data related to a credit transaction is input from the keyboard 5, the CPUI checks the reliability of the transaction based on the card data taken in from the card reader 16, and also makes inquiries to the host computer 8 as necessary. The program is set to execute the processing routine shown in the flowchart of FIG. 4 when it is determined that the credit transaction has been completed. That is, first, ST (
Step) 1: Create print data for one credit slip based on credit transaction data and card data, and store it in the slip buffer 31. Next, ST2
Read the status of I10 port 15 as
When it is confirmed that the credit slip 26 is set in the slip insertion slot 24 by the paper present output from ST.
3, the read pointer p of the area 32 of the RAM 4 is set to "1".
2, and set the print line number counter n in the area 34 to “
Initial reset to O''. Next, in ST4, one line of print data corresponding to the read pointer p is read from the slip buffer 31 and transferred to the print nozzle 33.After that, in ST5, the printer controller 13 The printing mechanism 11 and paper feeding mechanism 12 of the pick-up printer 10 are driven and controlled via the printer 10 to print one line of print data in the sofa 33 on the credit slip 26. (Print control (Means) When printing of one line on the credit slip 26 is completed in this way, the print line number counter n is incremented by "+1" in ST6. (Means for counting the number of printed lines) Also, read the status of I10 port 15 as ST7,
The state of paper detection by the slip sensor 14 is determined. Here, if the credit/soto slip 26 continues to be detected by the slip sensor 14, the read pointer p is set as ST8.
is incremented by "+1" and returns to ST4, where the one-line printing process for the print data in the slip slip 31 is continued in the same manner as above. Then, in ST9, when the print line number counter n exceeds the maximum line number N of the print data for one credit slip set in the slip buffer 31, printing is determined to be complete, and the ejection process of the credit slip 26 is performed as 5TLO. After doing so, this processing routine ends.

On the other hand, if the output from the slip sensor 14 changes to the paper out output in ST7 during the printing operation, the printing operation is interrupted and the output from the slip sensor °14 changes again to the paper presence output as 5TIL, or the keyboard as 5T12 The printer waits for an instruction to stop printing by key from 5. (Interruption Control Means) If printing is instructed to stop at 5T12, this processing routine is immediately ended.

On the other hand, when the output from the slip sensor 14 changes again to the paper present output at 5Tll, the credit slip 26 has been reset to the slip insertion slot 24, so 5T13
The paper feed mechanism 1 via the printer controller 13 as
2 is driven and controlled, and empty feeding of the credit slip 26 is performed by the number of lines counted by the print line counter n. Also, 5
The print buffer 33 is cleared as T14. moreover,
5T15, set the read pointer p to the print line number counter n
Reset to the value obtained by adding "1" to the count value. After that, the process returns to ST4, reads one line of print data corresponding to the read pointer p, and transfers it to the print buffer 33. Then, as ST5, the printing mechanism 11 of the slip printer 10 and the paper feed a! ! The horizontal axis 12 is driven and controlled to resume printing one line of print data in the print buffer 33 on the credit slip 26 from the interrupted position. (Resume control means) In this embodiment, when print data for a credit slip is generated by data input from the keyboard 5 host computer 8 and card reader 16, print data for one credit slip is created. It is stored in the slip buffer 31. In this state, when the credit slip 26 is correctly set in the slip insertion slot 24 of the slip printer 10, the print data in the slip buffer 31 becomes 1.
The data is sequentially read into the print buffer 33 line by line, and each time the print mechanism 11 and paper feed mechanism 12 are activated, the contents of the print buffer 33 are printed out on the credit slip 26. At this time, the number of printed lines on the credit slip 26 is counted by a printed line number counter n.

During this printing operation, for example, because the credit slip 26 is set at an angle, one side of the credit slip 26 misses the detection position of the slip sensor 14, and the output of the sensor 14 changes to a no-slip output. If so, the printing operation will be temporarily interrupted.

In such a case, the operator temporarily ejects the credit slip 26 from inside the printer cover 23 and checks the printing state. If it is determined that printing can be continued using the credit slip 26 that is currently being printed, the credit slip 26 is reset into the slip insertion slot 24. Then, the credit slip is empty-fed for the number of lines printed so far based on the count value of the number of printed lines counter n, and
Based on the value of the read pointer p, the printing operation is automatically restarted from the interrupted line number. In this way, the printing operation is continued from the interrupted position.

As described above, according to this embodiment, during the printing operation on the credit slip 26, the slip sensor 14 detects the credit slip 26 due to the inclination of the credit slip 26, etc.
6 is not detected and the printing operation is interrupted, the printing operation can be continued from the interrupted position by simply setting the credit slip into the slip insertion slot 24 of the slip printer 10. The slip 26 can now be reused as is. Therefore, there is no need to discard a slip that is being printed and start printing again from the beginning using a new slip as in the past, so that the waste of slips is eliminated and the time required for reprinting can be shortened.

In addition, if the printing condition of the credit slip 26 in the middle of printing is poor and it is impossible to continue printing, a manual key from the keyboard 5 is used to instruct the cancellation and the printing is started from the beginning using a new slip as in the past. It is also possible.

It goes without saying that the present invention is not limited to a slip printing device for credit slips, but can be applied to printing devices for various slips such as order slips used in restaurants, order slips used in retail stores, etc. That's a good thing.

[Effects of the Invention] As detailed above, according to the present invention, even if the slip sensor detects that there is no paper during the printing operation and the printing operation is interrupted, it is possible to remove the slip paper in the middle of printing with a simple operation. It is possible to provide a slip printing device that can be used as is and continue printing slips from the interrupted position, thereby preventing waste of paper and printing time.
