Description

Description: (a) Field of Industrial Application The present invention relates to an electronic cash register (hereinafter referred to as ECR) having a plurality of selection keys corresponding to a plurality of sales items.

(B) Prior art This type of ECR, as disclosed in Japanese Patent Laid-Open No. 57-111662, performs a sales registration operation by inputting a sales item desired by a customer with a selection key. .

(C) Problems to be Solved by the Invention However, when such an ECR is used in a store with a prepaid sales form, even if the sales item to be registered is sold out or the sales are stopped, the operator can If you do not notice it, there is a problem that it will be registered incorrectly. Further, even in the case of the post-payment sales form, when a sales item whose sales is stopped is mistakenly selected, the sales item whose sales is stopped is registered as it is.

Therefore, the present invention provides an ECR by making it possible to set the sold-out for each sales item so that the sales registration operation is not performed for the sales item set to be sold-out even if the selection key is operated. .

(D) Means for Solving the Problems In order to solve the above-mentioned problems, the electronic cash register according to the present invention has a plurality of selection keys provided corresponding to a plurality of sales items and a plurality of the sales items, respectively. A plurality of sold-out lamps provided corresponding to the sold-out setting key, and a sold-out setting mode is set in response to the operation of the sold-out setting key, and the sold-out flag is set for the corresponding product by operating the selection key. Check the set of sold-out flag for the corresponding sales item by setting the sold-out setting means to turn on the corresponding sold-out lamp and operating the selection key in the state where the sold-out setting mode is released. If the sold-out flag is set, the sales control means for making an error in the sales registration operation for the sales item is provided.

(E) Action By operating the sold-out setting key, the sold-out setting mode is entered, and when the sold-out setting means is subsequently operated by the selection key,
The sold-out flag is set for the corresponding product and the corresponding sold-out lamp is turned on. As a result, the sold item of this selection key becomes a sold-out setting, which can be visually confirmed by the sold-out lamp. When the sold-out setting mode is released and the selection key is operated, the sales control means determines whether the sold-out flag is set for the sales item corresponding to this selection key, and the sold-out flag is set. In this case, the sales registration operation for the sales item is set to an error.

(F) Embodiment FIG. 2 is a perspective view showing an ECR according to an embodiment of the present invention. A keyboard (4) is provided on the front surface of a housing (17) and above the keyboard (4). An indicator (15) for displaying the sales amount, total amount, etc. of the registered sales items and a receipt issuing port (18) are provided. And the housing (1
Below the 7) is a cash drawer (5). In addition, an indicator (1
6) is provided.

The keyboard (4) has various keys (FIG. 3) having the following functions.

(1) Selection key (7): Directly input the codes and prices of 30 kinds of preset products.

(2) Department key (8): Each is an independent sales item classification key, and a preset classification code is input.

(3) Numeric keypad (9): Enter the price of the sales item and the deposit amount from the customer.

(4) Clear key C: Used to correct the input on the numeric keypad (9).

(5) Subtotal key (10): Used to enter the price of a sales item using the numeric keypad (9).

(6) Total key (11): Used as a command to end the sale. When the total key (11) is operated when the total sale amount is received from the customer, the sale ends.

(7) Cash key (12): Operate when opening the cash drawer (5).

(8) Sold-out setting key (13): Operates when the sold-out item for each selection key (7) is set to be sold out.

Further, the keyboard (4) has a sold-out lamp (14) corresponding to each selection key (7).

Figure 1 shows the configuration of the ECR in blocks.
2) consists of CPU (1), ROM (2), RAM (3)
Reference numeral (1) is connected to a data bus (21) with a keyboard (4), a sold-out lamp driving section (19), a display (6) and a journal printer (20) for printing out receipts. The sold-out lamp driving section (19) is connected to the sold-out lamp (14) and drives the sold-out lamp (14) in response to a drive signal from the CPU (1). And the display (6) is CPU
The amount data given by (1) is displayed on the display (15), (1
Display in 6). Further, the CPU (1) connects the cash drawer (5) to the signal line (23) and gives a drive signal in response to the operation of the cash key (12) of the keyboard (4).

In the above-described configuration, the sold-out setting and the operation of the CPU (1) which causes the sales registration operation to be an error when the sold-out item set to the sold-out is selected will be described with reference to the flowcharts of FIGS. 4 and 5. To do. In this example, the CPU (1) operates as the sold-out setting means by performing the processing of the flowchart of FIG. 4, and operates as the selling control means by performing the processing of the flowchart of FIG.

The CPU (1) determines whether the sold-out setting key (13) has been turned on when step S1 is entered from the standby state, and if it is not turned on.
Performs other processing in ECR to return to the standby state. If the sold-out setting key (13) is turned on, the sold-out setting mode is set and the process proceeds to step S2. This step S2
Then, it is determined whether or not the selection key (7) is turned on, and if it is turned on, the process proceeds to the next step S3, and the sold-out flag is set by addressing the storage area corresponding to this sale item in the RAM (3). It is determined. If the sold-out flag is not set, the sold-out flag is set in the next step S4, and the drive signal of the sold-out lamp driving section (19) is driven so as to drive the corresponding sold-out lamp (14) in step S5. give. As a result, the sold-out flag is set in the RAM (3) for the sold item corresponding to the selection key (7) that is turned on, and the sold-out lamp (14) is also turned on to set the sold-out condition. When it is detected in step S2 that the selection key (7) has been operated again, the sold-out item is set for the sales item corresponding to the selection key.

Then the RAM (3) addressed in step S3
When it is detected that the sold-out flag is set in the storage area of, the CPU (1) clears the sold-out flag in the next step S6. Therefore, in order to cancel the sold-out of the sales item that is set to be sold-out, the selection key (7) corresponding to this sold-item may be operated in the same manner as when the sold-out is set.

When the selection key (7) is not detected to be ON in step S2, the process proceeds to step S7. When the sold-out setting key (13) is detected to be ON in this step, the CPU (1) exits the sold-out setting mode and Proceed to the routine for processing. Therefore, if the sold-out setting key (13) is operated once, it becomes the sold-out setting mode, and if it is operated a second time, the sold-out setting code is released.

When the CPU (1) goes from the standby state to step S10, it determines whether or not the selection key (7) is turned on, and when it is turned on, the sales registration operation for the sales item corresponding to this selection key is performed. First, in step S11, the CPU (1) executes the RAM
The storage area corresponding to this sales item in (3) is addressed to determine whether the sold-out flag is set. And if the sold-out flag is set, proceed to step S12,
Make the sales registration operation an error. However, if the sold-out flag is not set in the memory area of the RAM (3) addressed, the process proceeds to the next step S13, and the sales registration operation for this sales item is performed. Therefore, since the sales registration operation is performed on the condition that the sales item is not sold out, only the sellable sales item is registered.

(G) Effect of the Invention According to the present invention, a sold-out item can be set to be sold-out, so that it is not erroneously registered.
ECR function is improved.
