The present invention relates to receipt and audit paper processing in an electronic cash register, and more particularly, to a method and apparatus for detecting and reporting an ending state of an receipt and an audit paper to a user.

Conventional cash registers require a function to detect the endings of the receipts generated by the buyer and the end of the audit paper stored by the user as transaction data so that the paper (receipt and audit paper) can be exchanged at an accurate time.

The method of using a photo coupler as a means of detecting the ending state (publishing a domestic "teacher", see page 567 of the electronics dictionary) is to install the paper between the photo couplers so that the paper passes through the photo coupler. It has been detecting the paper and state by detecting whether or not through the photosensor. The method of using the micro switch (published in Korea, "Teacher", see Glossary of Electronics, p. 703) is to switch on the paper when the paper is pressed by putting the micro switch where the paper is placed. When consumed, it was turned off to check the Paper Eng status.

As described above, both conventional methods are hardware methods, which not only complicates the configuration but also allows the paper ending state to be known only when the paper is exhausted. There was a problem that could not be.

Accordingly, an object of the present invention is to provide a method and apparatus for allowing the user to know the paper consumption in advance and then replenish the paper ending state in a timely manner so that the user can select the time of paper change due to the paper end at a user's convenient time. have.

The present invention for performing the above object is an input process of inputting the length according to the corresponding use by the receipt and audit paper selection key by inputting the total length value of the paper, and the completion of the receipt and audit paper length input in the input process The paper length calculation and setting process of calculating and setting the length of the received and audited paper by calculating the length of the paper and the setting of the paper length, and the searching and counting of the received and audited feeding extras after completing the paper length setting. And a feedback conversion process for converting the total audit paper and the resin feed distances according to the counting increase value in the feeding process, and comparing the result value and the set value of the feedback conversion process with the total resin and When the feeding length of the audit paper is out of the setting length is characterized in that the output process to display the paper ending state.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The configuration for realizing the present invention is shown in FIG.

A keyboard 13 for generating key data and various commands for the plate activity, a CPU 11 for controlling each part of the system, a ROM 6 for storing various control processing programs and initial data, RAM 4 for storing various processing data in accordance with the occurrence of transaction activity at a time, display unit 12 for displaying data generated during sales activities, printer 10 for recognizing receipts and audit papers, and cash storage cash It consists of a drawer 17.

2 shows an area for storing the receipt and audit paper set lengths calculated from the receipt and audit paper lengths and the extra lengths stored in the RAM 14, and the printing feed from the receipt and audit feedback counting values. Feeding) shows an area for storing the converted values of total receipt and audit feeding distance by multiplying the distance.

3 and 4 are flowcharts of the process according to the present invention, and FIG. 3 is a flowchart for initially setting the length of the resin sheet audit paper in the program mode, and FIG. 4 is the input key for the paper length and the resin or audit Confirm the selection of the paper, set the receipt and audit paper by subtracting from the extra length already stored as data in RAM 14 at the currently input paper length, and informing the ending state according to the use of each function in the set value. It is for.

Looking at the relationship between the embodiments of the present invention are as follows.

Input process of inputting paper length and input length according to use of relevant receipt and audit paper by using receipt and audit paper selection key, and calculating extra length when completion of receipt and audit page length input in the input process Paper set length length and setting process for calculating and setting the length to be set, paper feed process for searching and counting the feeding extras of receipt and audit paper after completing the paper length setting, and counting increase value in the feeding process. According to the feeding conversion process for converting the feeding and feeding distance of the total audit and the receiving resin, and the result value of the feeding conversion process and the set value is compared with the feed length of the total receipt and audit paper It is an output process that displays the paper ending status when it is out of the setting length.

In the present invention, the above-described execution of the procedure was specifically shown by the computer program using the CPU 11, but a person having ordinary knowledge in this field uses the logic gate in the same technical spirit as described above, It can be configured easily.

Of course, the paper length input start key, the resin, the audit paper selection key, the paper length input key, and the paper length input completion keys are already promised.

Referring to the operation according to FIG. 3, in the program board of step (3a), the paper length input start key is pressed in step (3b), and in step (3c) and (3d), the selection of the receipt or audit paper is confirmed. When the paper length is input in step (3e) and the paper length input completion key is input in step (3g), the CPU 11 inputs the paper length already input to the currently input paper length. The extra length already stored in the RAM 16 as data is extracted in the process (3h), and the set length of the receipt and audit paper is stored in the recording section of the ROM 16 or the RAM 14.

When the audit paper selection key is not the receipt paper selection key in step (3e), the audit paper paper length is input in step (3f), and the length of the paper is converted by checking whether the paper length input completion key is checked in step (3i). Set the audit paper length in step (3j). This means that the cash register recognizes the paper length as the original paper length minus the extra length. For example, if the 10m paper has an extra length of 50cm, the paper length is recognized as 10m-50cm = 9.5m, and the paper end state is notified when the paper is consumed 9.5m.

In FIG. 3, a process of setting a substantial paper length, sensing a paper end in FIG. 4, and informing a user of the paper end will be described.

After performing general variable processing in (4a) and checking whether there is a receipt feeding in (4b), the feeding counter of the second degree is increased. In addition, the feeding distance at the time of feeding once, that is, the number of receipts and audit feed counters, should be stored in the RAM 14 of the cash register as data. The total resin feeding distance is multiplied by the printer feeding length by the receiving feed counter and stored in the corresponding area of FIG.

Compare the total Resin Feeding distance you have already calculated with the length of the Receiving Paper Set set in Figure 3 in Program mode. In comparison, if the total feeding distance is larger than the set paper length, the consumption of the paper is displayed.

Receipt paper end (RPE) for the end of the resin paper, and JPE (Jourmal Paper End) for the ending of the audit paper are displayed for the user to know.

This allows the user to see these messages when using the 9.5m of the 10m paper, for example. That is, it checks whether the resin and audit paper feeding in the process (4b), (4g).

In step (4b), the resin feed feeding counter is increased in step (4c), and in step (4g), the audit paper feeding counter is increased in step (4h). The total receipt and audit paper feeding distances are calculated in steps (4d) and (4i) according to the receipt and audit paper feeding, and an increase value of the resin and audit paper feeding counters of the processes (4c) and (4h) is calculated. Multiply the printer feeding distance by the distance of total resin and audit paper, and compare with the set length of the receipt and audit paper in (4e) and (4j).

If the total resin and audit paper feeding distances are greater than the set lengths in the above processes (4e) and (4j), the "RPE" or "JPE" state is displayed in the processes (4f) and (4k).

In the cash register constructed as shown in FIG. 1, the display portion 12 is mostly a liquid crystal display (LCD).

The indication is indicated by the 7-segment. Therefore, the comparator 11 shows that the total resin feeding distance 301 read from the RAM 14 is larger than the length of the receipt paper set 203 as shown in FIG. And the display unit 12 is controlled so that "RPE" is displayed on the 7-segment LCD.

On the other hand, the comparator that the central processing unit (CPU) 11 reads from the RAM 14 in the process (4j) as shown in FIG. 2 shows that the feeding distance 302 is larger than the length of the audit paper feeding set. Display unit 12 is controlled to display " JPE " on the 7-segment LCD.

As described above, since the paper ending is sensed by a program without various circuit devices or mechanical devices, there is an advantage that a cash register manufacturer can easily exchange a missed exchange time as well as a user.
