Abstract

PURPOSE:To avoid a misoperation due to the operation of an unnecessary key as well as the needless print to a receipt, etc. by storing the prescribed contents to the store area of a descriptor corresponding to a prescribed key. CONSTITUTION:The contents corresponding to an operation key are stored in a store area of a descriptor 14 of an RAM 3. Then the contents of the descriptor 14 are printed by a printer 5 in accordance with operation of keys and also displayed to a display device 4. For instance, a department key is operated to print and display the contents (department) of an area 14a. While the contents (cash) of an area 14b are printed and displayed with operation of a cash key. In this case, a user who needs no function of a credit sale key stores previously a space code in an area 14c. Thus the credit sale key is disabled. In other words, a misoperation is displayed when the credit sale key is operated by mistake. Then the subsequent operations are inhibited. This avoid a misoperation due to the operation of an unnecessary key as well as the operation of a needless print.

Description

TECHNICAL FIELD The present invention relates to an electronic cash register, and more particularly to the configuration of an operation process according to key operations.

BACKGROUND ART General-purpose electronic cash registers are equipped with a wide variety of functions, and therefore may include functions that are not necessary for individual users. Keys for such unnecessary functions are all operators accidentally operating the cash registration process?
Sometimes I make mistakes. Additionally, unnecessary printing corresponding to unnecessary functions is performed on receipts and reports.

In order to solve this problem, conventionally, unnecessary keys provided on the keyboard are removed. In such prior art, the keys are removed from the keyboard so that the holes left after the keys are removed are visible and look unsightly. Also, unnecessary characters are still printed on receipts and reports.

In Ike's prior art, the program can be changed to permit or prohibit the use of each key. Although such prior art eliminates the risk of an operator making a mistake by operating an unnecessary key, and avoids unnecessary characters being printed on receipts and reports, the program is complicated. , the programmability setting work is complicated.

Purpose Is the purpose of the present invention to eliminate unnecessary keys? It is possible to easily prevent erroneous operations4 due to unnecessary key operations and avoid unnecessary printing on receipts, reports, etc. with simple operation without removing it from the keyboard and therefore without deteriorating the aesthetic appearance. An electronic cash register? It is to provide.

Structure and Effects of the Invention The present invention provides an electronic cash register which, when a key is operated, reads and prints stored contents from a disk printer having a storage area individually corresponding to each key. A predetermined content is stored in a storage area of a disc libter corresponding to a key, and when the predetermined key is operated, the predetermined content is stored. Is there a disabling process such as reading and displaying an operation that indicates an erroneous operation or prohibiting subsequent operations? What to do? This is a distinctive electronic cash register.

According to the present invention, a predetermined content is stored in a store area corresponding to a predetermined key among the store contents for each key stored in a disc libter, and the predetermined content is read to indicate that an erroneous operation has occurred. Disabling processing such as displaying or prohibiting subsequent actions? I decided to do it, so
No unnecessary keys are removed from the keyboard, so the aesthetics are not degraded. In addition, if the predetermined key is operated by mistake, an inoperable (I) process is performed, so erroneous operations can be avoided.Furthermore, it is relatively easy to store the predetermined contents in the storage area of the disc libter. It is possible to simplify the configuration.

In this example, it is assumed that the credit key IO may or may not be needed depending on the user.

FIG. 8 is a diagram showing the storage status of the disc libter 14 stored in the random access memory 3. When the department key 8 is operated, the printer 5 prints the content "Bumon" in the store area 14B. Further, when the cash key 12 is operated, the contents of the store area 14b are read out and the printer 5 prints "1 Genkin". Store content "Kakeuri" is stored in the store area 14C in correspondence with the credit key IO. By storing such store contents in the disk printer 14, printing is performed by the printer 5, and display is also performed by the display 4.

As shown in FIG. 3(2), by storing predetermined contents, ie, space codes, in the store area 14C corresponding to the credit key 10, the operator can Credit key 10? In case of erroneous operation, a disabling process is performed as described later.

The random access memory 3 also includes a tabulator 15 for each department, a cash tabulator 16, and a credit tabulator 1, as shown in FIG.
7 is provided.

Furthermore, the random access memory 3 is also provided with a number register 18, a data number area 19, and an itemizer 20.

When the mode switch 18 is operated to enter the setting mode, the data number is input using the numeric keypad 7 as shown in FIG. cash key 12ft
Manipulate. In this way, the price of the product corresponding to the data number can be input and set.

It is added to 5. The itemizer 2o has a function of accumulating each customer's monetary registration.

When it is determined in step nto that the subtotal key 11 has been operated and it is determined in step nil that this operation mode is the setting mode, step n1
2, the contents of the numeric register 18 are data number area 1.
It is stored in 9.

When the subtotal key 11 is operated in an operation mode other than the setting mode, the process moves to step nta, where it is determined whether the mode is registration mode, and if the mode is registration mode, the subtotal key stored in the disk printer 14 is pressed in step n14. The contents "Nyoukei" stored in the store area corresponding to No. 11 are read out, and the contents of the itemizer [¥1800J] are displayed.

When it is determined in step n15 that the cash key 12 is operated, the process moves to step n16, and it is determined whether the setting is the same, and if so, in step n17, the entire contents of the register 1/register 18 are converted. and stores it in the area of the disc libter 14 corresponding to each key specified by the data number. If it is determined in step n16 that it is not the setting mode, the process moves to step n18, and it is determined whether the mode is registration mode, and if so, the content "Genkin" is read from the store area 14b of the disc libter 14 and displayed in step n19. At the same time, printing is performed by the printer 5 in step n20. In step n21, the contents of the itemizer are added to the cash totalizer 16, and the itemizer is added to the cash totalizer 16 in step n21.
Cleared at 22.

When the credit key 10 is operated in the registration mode, the process proceeds from step 12B to step 124 and then to step n25. In step n25, it is determined whether the contents of the store area 140 of the disc libter 14 corresponding to the credit key IO are space codes. As shown in FIG. 3 (1), if no space code is stored in the store area 14C and the stored content is "Kakeuri", step n26KK is executed, a message to that effect is displayed and the itemizer content is "¥2000". is displayed, and printing is performed by the printer 5 in step n27. step n28
Then, the contents of the itemizer are added to the credit totalizer 17,
Thereafter, the itemizer is cleared in step n29.

When a space code is stored in the store area 140 corresponding to the credit key IO of the disc libter 14 as shown in FIG. 3(2), error processing is performed after execution of step n25. This error processing involves, for example, displaying on the display 4 that it is an erroneous operation, and prohibiting subsequent operations, thereby performing a disabling process.
