DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register which is installed in various stores and registers sales information such as the sales volume and sales amount of goods.

[0002]

2. Description of the Related Art Conventionally, an electronic cash register (hereinafter referred to as ECR) has been used.
), A master reset is executed as necessary. The master reset is to erase (clear) various setting conditions necessary for registration set by the operator in the ECR and to set them to an initial state. This master reset is required when the usage environment of the ECR is significantly changed, for example, when the type of product or the price of the product is changed, or when the installation location is changed in a large store, or when the type of the product is increased. This is executed when a memory is added to increase the storage capacity.

FIG. 5 is a flowchart for explaining the operation after a master reset in the conventional ECR. After the master reset is performed in step a1, step a
Each of the operations 2 to a4 can be arbitrarily executed according to the operation of the operator. In step a2, a date such as the current date and time is set for the clock circuit built in the ECR. In step a3, a registration process executed when selling a product to a customer is performed. In step a4, the date setting in step a2 and step a2
Various processing operations other than the registration processing of No. 3 are executed.

FIG. 6 is a flowchart for explaining a registration process in the conventional ECR. When there is a key input in step b1, the sales information input in step b2 is registered. In step b3, the registered sales information is printed on the receipt, and the process returns to step b1 to wait for the next key input.

[0005]

In the conventional ECR, registration processing can be performed even when the clock circuit is reset by a master reset. The clock circuit in this case has an initial value preset for the clock circuit,
For example, clocking is started from the manufacturing date set at the time of manufacturing the ECR or “0”, and the clocking result is output as a date, or the clocking operation is not performed.

Therefore, sales information may be registered on an incorrect date, and the sales information may be printed on a receipt. This is because it is not confirmed whether the date has been set after the master reset.

An object of the present invention is to provide an electronic cash register that can prevent forgetting to set an initial value for a timer after initialization.

[0008]

According to the present invention, a plurality of operating states are set including a predetermined initial state by a master reset and a registration operating state for registering sales information including an input sales quantity and a sales amount. In an electronic cash register, a clocking means for performing timekeeping operation and outputting time information including at least the date and time, an initial value setting means for setting an initial value to the timekeeping means after a master reset, and a master reset A flag which becomes one predetermined logical value, and which becomes another predetermined logical value by the initial value being set by the initial value setting means after the master reset, a detecting means for detecting the logical value of the flag, In response to the output, when the flag is the other logical value, the input sales information includes a total at the time of inputting the sales information. And registration process by adding the time information by means an electronic cash register which comprises a registration means does not execute the registration process when the flag is the one logic value.

[0009]

According to the present invention, when the electronic cash register is set to the initial state by the master reset and the clocking means is also set to the initial state, the flag is set to one logical value, for example, in the embodiment described later. At this time, the time information output from the clock means is not accurate time information, and the detecting means detects that the flag is one of the logical values, and executes the registration processing by the registering means. Don't do it. After the master reset, when the initial value, which is the current accurate time information, is set in the timekeeping means by the initial value setting means, the flag becomes the other logical value, for example, logical "1". ,
Since the flag is the other logical value, the input sales information is added with the time information at the time of inputting the sales information, and is registered. By setting the initial value in the timekeeping means in this manner, registration of sales information becomes possible, and accurate time information is added to sales information and registration processing is performed.

FIG. 1 is a block diagram showing an electrical configuration of an electronic cash register (hereinafter, referred to as ECR) 1 according to an embodiment of the present invention. The ECR 1 includes a control unit 2 realized by a microcomputer or the like. The control unit 2 is connected to a key input unit 3, a display unit 4, a clock circuit 5, and a processing unit 6.

The key input unit 3 includes a plurality of key switches, which will be described later, and is operated when instructing input of sales information, setting of an operation state of the ECR 1, and the like. The display unit 4 displays α
-It is composed of a numeric tube, a liquid crystal display device, etc., and displays input sales information, ECR1 operation information, and the like. The clock circuit 5 executes a timekeeping operation from the initial value set by the control unit 2 and outputs time information such as date and time such as date.

The processing unit 6 is controlled by the control unit 2,
A program for controlling various operations of the ECR 1 is read from a read only memory (ROM) 7, and a sales information registration process or the like is performed based on the read program using a work area set in a random access memory (RAM) 8. Run. The processing unit 6 controls the print control unit 9 to print the receipt and the journal by the printing unit 10. Further, the processing unit 6 controls opening and closing of the drawer 11.

FIG. 2 is a plan view showing a key arrangement of the key input section 3. As shown in FIG. The key input unit 3 includes a function changeover switch 23
The operation state of the ECR 1 is stopped by using a key (key) held by the operator, the responsible person or the administrator,
Necessary for two types of program operation states for entering the product name and unit price of the traded goods handled, time operation state for enabling time and date setting change, registration operation state for executing normal cashier operations, and management of ECR1 It can be switched to any of a management operation state for inputting / outputting various kinds of data and an inspection / payment operation state for executing the inspection and registration contents of the ECR 1 on a daily and monthly total.

The key input unit 3 includes a numeral key 24,
A transaction mode key 25 for inputting transaction modes such as credit sales and credit sales, and a cash / exchange key 26 operated for cash sale registration, deposit calculation (change calculation) or currency exchange are arranged.

The key input unit 3 further includes a plurality of department keys 28 for designating a department to which the product belongs when the product is registered, and a PLU.
(Price Look Up) code, PLU key 29 used to register sales, JAN (Japanese Article Numbe)
r) JAN used when registering sales by code
The key 30 is arranged.

FIG. 3 is a flow chart for explaining the operation after a master reset in ECR1. When the master reset is performed in step n1, the date setting flag F is set to 0 in step n2. Thereafter, each of the operations in steps n3 to n4, step n5, and step n6 is arbitrarily executed according to the operation of the operator.

In step n3, a date is set from the key input unit 3. The date is set, for example, by inserting the above-mentioned key into the function changeover switch 23 and turning it to the position of “time” to set the time operation state, and inputting the date and time from the numeral key 24. At step n4, the date setting flag F = 1 is set. By reading the date setting flag F, it can be determined whether the date and time, which are the initial values for the clock circuit 5, have been set.

At step n5, sales information registration processing is performed. In step n6, processing other than the above-described date setting and registration processing is executed.

FIG. 4 is a flowchart for explaining the registration processing of sales information in ECR1. If there is a key input from the key input unit 3 in step m1, the process proceeds to step m2. At step m2, it is determined whether or not the date setting flag F = 1. If the flag F = 1, the process proceeds to step m3, where sales information is registered. At step m4, the registered sales information is printed on a receipt. If the flag F is not 1 in step m2, a miss operation process is performed in step m5,
That is, it is determined that the key input is incorrect and the key input is not accepted. Thereafter, the process returns to step m1, and waits for the next key input.

As described above, according to this embodiment, ECR1
If the date is not set in the clock circuit 5 after the master reset is performed on the clock circuit 5 and the clock circuit 5 is reset, the registration processing of the sales information is not executed.
This prevents registration of sales information and printing on a receipt on an incorrect date, and allows the operator to easily know that the date has not been set after the master reset. Therefore, the convenience and operability of the ECR 1 are remarkably improved.

[0021]

According to the present invention, after the electronic cash register is set to the initial state by the master reset and then the initial value of the clock means is set by the initial value setting means, the flag is changed from the one logical value to the above-mentioned one. On the other hand, it changes to a logical value,
The registering means adds the time information by the timekeeping means at the time of inputting the sales information to the input sales information when the other logical value, and performs the registration processing when the flag is the one logical value. Since the processing is not executed, it is possible to reliably prevent the registration of sales information due to an incorrect date. As described above, according to the present invention, for example, when it is desired to correctly reset the time information of the timekeeping means in the electronic cash register, for example, a master reset is performed, and an initial value is set. When a logical value is reached, registration processing can be executed for the first time, so that accurate time information can be added to input sales information without fail.
