Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic cash register (hereinafter referred to as an ECR), and particularly to an ECR in which predetermined information can be set and stored, for example.

Description of Prior Art In conventional ECR, when inputting the unit price of a product, it was necessary to input the unit price for each product even if there were many products with the same unit price. Therefore, in conventional ECR,
This has the disadvantage of increasing the burden on the operator. In addition, since the same unit price is inputted continuously, users often forget how many times they have inputted it, leading to input errors.

OBJECTS OF THE INVENTION Therefore, the main objective of this invention is to provide an ECR that allows easy key operations when inputting the same amount many times.

Structure and Effects of the Invention To summarize, the present invention provides a method in which only information regarding the amount of money is preset and stored in correspondence with a predetermined key among a plurality of keys included in a key manual means, and when the predetermined key is operated. In this case, information regarding the corresponding amount is read out.

According to this invention, when the same amount is used frequently, key operations for inputting the amount can be simplified. Therefore, the burden on the operator can be reduced, and the occurrence of erroneous input can be reduced.

Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.

including. These storage areas 35a, 35b, . . . are used as areas for setting and storing predetermined amount information in advance (hereinafter referred to as amount setting area). . In this embodiment, the amount setting area 35a is the amount setting key 44 described above.
The amount setting area 35b is an area corresponding to the amount setting key 45 described above.

FIGS. 4(a) and 4(b') are illustrative views showing an example of a key operation procedure for setting the amount setting areas 35a and 35b(7) shown in FIG. In particular, Figure 4 (a
) shows an example of the setting operation for the amount setting area 35a, and FIG. 4(b) shows an example of the setting operation for the amount setting area 35b. FIGS. 5(a) and 5(b) are illustrative views showing an example of the key operation procedure for the amount setting keys 44 and 45 in the registration mode.

6 and 7 are flowcharts for explaining the operation of the embodiment shown in FIG. 1. In particular, FIG. 6 shows the setting operation of the amount setting areas 35a, 35b, . . . in the setting mode, and FIG. 7 shows the registration operation in the registration mode.

The operation of the embodiment shown in FIG. 1 will be described below with reference to FIGS. 4 to 7.

First, the amount information setting operation in the setting mode will be described with reference to FIGS. 4 and 6.

First, as shown in FIG. 4, the operator operates the numeric keys 42 to input amount information to be set.

The input of this amount information is determined in steps 1 and 2 (abbreviated as S in the illustration) shown in FIG. and,
In step 3, the input amount information is stored in the numeric buffer NB. Furthermore, in step 4, a numeric flag FN is set. After that, the operation returns to step 1 again.

Next, as shown in FIG. 4, the amount setting key 44 or 45 is operated by the operator.

The operation of these amount setting keys is performed in step 1 shown in FIG.
．． 2 and 5, and in step 6 it is determined whether or not the 7 lag FN is set. if,
If the number flag FN is not set, it is determined that there is an error in the key operation procedure, and error processing is performed in step 7. On the other hand, if the number flag FN is set, the process advances to step 8. In this step 8, the stored contents of the number buffer NB are transferred to the corresponding amount setting areas 35a, 35b, . That is, if the amount setting key 44 is operated, the contents stored in the number buffer NB (amount information to be set) are transferred to the amount setting area 35m. Further, if the amount setting key 45 is operated, the stored contents of the same number of buffers NB are transferred to the amount setting area 351). Subsequently, in step 9, the number of the amount setting key and the set amount information are printed by the printer 6. And step 10
Proceeds to , the 7 lag FN is reset, and the 7 lag is reset.
NB is cleared.

The above series of operations is repeated, and predetermined amount information is set in the amount setting areas 35a, 35b, . . . .

In this embodiment, since two amount setting keys 44 and 45 are provided, amount information is set in the corresponding amount setting areas 35a and 35b, respectively. Of course, three or more amount setting keys may be provided. Here,
In the example shown in FIG. 4, r500 is set in the amount setting area 35a.
J is set. In addition, in the amount setting area 35b, r
ooOJ is set. Note that this roooJ is treated as rX 1000J in calculation.

Next, the registration operation in the registration mode will be explained with reference to FIGS. 5 and 7. For example, in Figure 5 (a
), when the operator operates the amount setting key 44, this causes steps 11.12 and 1 in FIG.
It will be judged by 5. Then, in step 16, the numeric flag FN is set, and it is determined whether or not it is.

In this case, since no numerical information has been entered, the
Lag FN remains reset. Therefore, proceed to step 17. In step 17, the amount information is read from the amount setting area 35a corresponding to the operated amount setting key 44 and stored in the number buffer NB1\. Then, in step 18, a 7-lag FN is set.

Next, as shown in FIG. 5(a), the operator operates the department key 43 and inputs the department code.

Enter this department code in steps 11 and 12 in Figure 7.
．． Judgments are made in steps 15 and 23, and the process proceeds to step 24. In step 24, it is determined whether the numeric flag FN is set. If the number flag FN is not set, it is determined that there is an error in the key operation procedure, and error processing is performed in step 21.

On the other hand, if the numeral norag FN is set, the process advances to step 25. In step 25, the amount information (r500J in this case) stored in the number of strokes buffer NB is added to the total amount area iM. As a result, the total amount area iM is updated. Subsequently, in step 26, the display 5 displays the amount information of the numeric buffer 7NB. Then, in step 27, the numeric buffer NB
amount information is printed by the printer 6. moreover,
In step 28, the numeric value flag FN is reset and the numeric value buffer NB is cleared.

As described above, when the key operation shown in FIG. 5(a) is performed, the amount r500Jp is added to the area corresponding to the department code DP1 of the total amount area iM.

Next, as shown in FIG. 5(b), the operation when inputting an amount using the amount setting key 45 will be described. In this case, the operator inputs numerical information using the numerical keys 40. The input of this numerical information is determined in steps 11 and 12 of FIG. 7, and the input numerical information is stored in the numeric buffer NB in step 13. Then, in step 14, the numeral nolag FN is set.

Next, as shown in FIG. 5(b), the operator operates the amount setting key 45. The operation of this amount setting key 45 is determined in steps 11.12 and 15 in FIG. Then, the process proceeds to step 16, where it is determined whether the numeric flag FN is set or not. In this case, since the numeric flag FN has already been set in step 14, the process advances to step 19. In this step 19, amount information is read from the amount setting area 35b corresponding to the operated amount setting key 45, and is transferred to the work area WORK. Subsequently, in step 20, the work area W
It is determined whether the stored content of ORK is only 0. if,
If there is information other than O in the storage contents of the work area WORK, error processing is performed in step 21 because the work area WORK stores incorrect information.

On the other hand, if all the stored contents of the work area WORK are O, the process advances to step 22. In this step 22, the contents stored in the number buffer NB are transferred to the work area WOR.
It is shifted to higher order digits by the number of O's stored in K. That is, in this case, the contents stored in the numeric buffer NB will be multiplied by ``x1000''.

Next, as shown in FIG. 5(b), the operator operates the department key 43 and inputs the department code.

Enter this department code in steps 11 and 12 in Figure 7.
．． 15 and 23. The subsequent operation is the fifth
The operation is similar to the operation when the department code is input in Figure <a>.

As explained above, in the above embodiment, predetermined amount information can be generated simply by operating the amount setting key 44 or 45. Therefore, when the same amount of money is often handled, the operator's key operations can be simplified.
