Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a data processing device such as an electronic register, a POS system, and an office computer.

[Prior Art] In recent years, a hand scanner is equipped with a PLU memory or a registered memory, and based on a bar code read by this hand scanner, the hand scanner itself stores the total number of sales by PLU, etc. Performs registration processing such as storing sales data for one registration, connects this hand scanner to the electronic register body, transmits the contents of one registration memory to the electronic register body, and issues a receipt at the electronic register body. An electronic cash register is being considered.

In such an electronic register, the bar code number, unit price, etc. to be preset in the PLU memory of the hand scanner are supplied from the electronic register body side when the hand scanner is connected to the electronic register body.

[Problems to be solved by the invention] By the way, in stores, for example, prices of a plurality of products may be collectively reduced from the afternoon. in this case,
The unit price of all reduced prices is the PL of the hand scanner
Until it was rewritten on the U memory, no matter how busy I was, I could not perform the registration process using the hand scanner.

The problem of this invention is to input the classification data from the terminal even during the process of changing the preset data for the classification to be set in the terminal, and regarding the classification data,
The data processing can be performed based on the preset data related to the change.

[Means for Solving the Problems] The means of the present invention are as follows.

The data processing device is composed of a host machine such as an electronic register and a terminal machine such as a hand scanner that is detachably connected to the host machine to exchange data. The data transfer is performed, for example, to issue a receipt in an electronic register based on sales data for one registration that is registered by the hand scanner in the non-wearing state.

The supply means of the host machine supplies, to each terminal, predetermined preset data such as a unit price relating to the classified data for each classified data such as a bar code indicating a product classification.

The first storage means of the terminal device stores the classification data and the preset data supplied by the supply means.

The second storage means stores, for the classification-based data in the first storage means, data indicating that the corresponding preset data is not yet rewritten to the preset data related to the change from the supply means.

The input means inputs data by classification and the like.

When the classification data is input from the input means, the processing means accumulates, for example, the total sales amount for each product based on the corresponding preset data in the first storage means, and the bar of the product for one registration. Performs data processing such as registering codes and unit prices.

When the classification data is input by the input device in a state where the terminal device is removed from the host machine, the determination means determines whether or not the preset data corresponding to the classification data is changed. It is determined based on the storage means.

The temporary storage means, when it is determined by the determination means that the preset data has not been changed, temporarily stores the input classification data when the classification data is input by the input means. .

When the determination unit determines that the preset data has not been changed, the control unit controls the classification data stored in the temporary storage unit when the terminal is attached to the host unit. The preset data is inquired to the host machine and written in the first storage means, and the processing means is caused to perform data processing based on the preset data relating to the change.

[Operation] The operation of the means of this invention is as follows.

For example, when the bar code (classified data) of each product and the unit price (preset data) of the product are supplied from the supply device of the host device, the first storage device of the terminal device supplies them by product. Remember.

Further, for example, when the first change unit price is supplied from the supplying unit, when the signal for starting transmission of the change unit price is received from the host machine, the second storage unit is supplied with the change unit price for which product. For the time being, it is unclear whether the unit price change unprocessed flag is set and stored as data indicating that the changed unit price from the supply means has not been rewritten for all the classified data in the first storage means. . This unit price change unprocessed flag is reset when the current unit price is rewritten to the changed unit price, but the unit price change unprocessed flag remains set for all products for which the changed unit price has not been supplied. .

Now, it is assumed that the bar code is input by the input means in a state where the terminal device is detached from the host device. Then, the determination means determines whether or not the unit price change processing of the product corresponding to the barcode has been performed based on the unit price change unprocessed flag in the second storage means. When it is determined by the determination means that the preset data has not been changed, when the classification data is input by the input means, the input classification data is temporarily stored in the temporary storage means. However, when it is determined by the determination means that the preset data has not been changed, the preset data relating to the classification data stored in the temporary storage means when the terminal is attached to the host machine. Is written in the first storage means, and the control means causes the processing means to perform data processing based on the preset data related to the change.

Therefore, even during the process of changing the preset data for each category to be set in the terminal, the data for each category is input from the terminal, and the data for that category is processed based on the preset data related to the change. It can be performed.

[Embodiment] An embodiment will be described below with reference to FIGS. 1 to 9.

FIG. 2 is a circuit block diagram of each hand scanner A. The reading head unit A1 has a light emitting diode group 11, a lens system 12, and a CCD array 13.

In the reading head unit A1, the light from the light emitting diode group 11 is applied to the bar code symbol printed on the wrapping paper of the product, and the reflected light is transmitted through the lens system 12 to the CCD array 13
Then, the CCD array 13 photoelectrically converts the incident light in which the pattern of the barcode symbol is reflected. Then, the recognition unit 14 analyzes the electrical pattern signal as the conversion result, recognizes the content of the barcode (barcode number), and outputs it to the CPU 15.

The key input unit A2 has a number key 2a for inputting the number of sales, a bar code and the like, and a receipt key 2b for instructing receipt printing. The input data from the key input unit A2 is also output to the CPU 15.

When the barcode is input from the key input unit A2 or the recognition unit 14, the CPU 15 performs a predetermined process according to a program stored in the ROM 16 in advance, stores the processing result in the RAM 17, displays it on the display unit A3, etc. Control. Also, CPU15
When the hand scanner A is placed on the scanner table B3 of the repeater B, the control is performed such that data is transmitted and received to and from the repeater B via the optical transmission / reception unit 18.

A PLU file FA and a registered memory MA are formed in the RAM 17.

As shown in Fig. 4, the data items of the PLU file FA record are the bar code of each product, product name, unit price change processing flag, unit price, number of sales under change, total number of sales, total amount of sales. There is.

The unit price change unprocessed flag of each record is set when the first changed unit price from the repeater B is received, and thereafter,
It is reset when the current unit price is rewritten to the changed unit price.

Then, before the transmission end signal of the changed unit price is received from the repeater B, the hand scanner A is set on the scanner table of the repeater B.
When the bar code of a product with the unit price change unprocessed flag set, that is, a product whose unit price has not been changed is input from B3, the sales quantity of the product corresponding to that bar code is It is registered as the number. Then, the total sales amount based on the number of sales under change is updated by inquiring the relay unit B of the unit price for change when the hand scanner A is mounted on the scanner stand B3 of the relay unit B later.

On the other hand, when the bar code of the product for which the unit price change unprocessed flag is reset is entered, the sales quantity of the product corresponding to the bar code is added to the total sales quantity, and at that time, the total sales price is also calculated. Will be updated.

When the barcode is entered, the unit price of the corresponding product is displayed along with the entered barcode on the display unit A3, but when the unit price change unprocessed flag is set,
The unit price before the change and the fact that the unit price may have been changed are displayed.

Further, the secondary battery 19 is charged by the relay device B when the secondary battery 19 is placed on the scanner stand B3 of the relay device B.

FIG. 4 is a circuit block diagram of each repeater B. After the hand scanner A is placed, the CPU 51 supplies the bar code and unit price to the hand scanner A according to a program stored in the ROM 52 in advance. Based on the sales data for one registration from the hand scanner A, control such as receipt printing is performed. Data exchange at this time is performed via the optical transmission / reception unit 53.

A modified PLU file FB is formed in the RAM 55. The modified PLU file FB includes an inline L and a transmission control unit 56.
The bar code transmitted from the register C of the head office via the and the unit price of change of the product indicated by the bar code are stored. This change unit price is the same as the hand scanner A when the hand scanner A is placed on the scanner stand B3 of the repeater B.
Sent to and cleared.

A commercial alternating current is supplied to the power supply circuit 57, which is converted into direct current and supplies a power supply voltage of 5 volts to each circuit. Charging circuit
The reference numeral 58 supplies a charging current to the secondary battery 19 of the hand scanner A when the hand scanner A is placed.

The receipt printing unit B1 prints the sales data for one registration as a receipt content, and the drawer B2 stores the amount of money.

Next, the operation of the embodiment will be described.

First, the process of supplying the changed unit price of the repeater B will be described with reference to FIG.

The CPU 51 of the repeater B changes the bar code and the unit price for change (maintenance information) when the bar code and the unit price for change are transmitted from the register C of the headquarters together with the change command signal.
Store in file FB. Then, it is judged whether or not the hand scanner A is connected (step B1), and when it is connected, the bar code and the change unit price for one record of the change PLU file FB are transmitted together with the interrupt request signal. (Step B2).

Next, it is judged whether or not the hand scanner A is in a state of waiting for the interrupt reception of the maintenance information within a predetermined time (step B3). As a result, when it is not in the state of waiting for the interruption reception of the maintenance information, as will be described later, the hand scanner A is removed from the relay device B or the maintenance information is correctly transmitted to the hand scanner A. Since it is possible that there is no such thing, step B1
Then, the same maintenance information is sent again.

On the other hand, when the hand scanner A is in the state of waiting for the interrupt reception of the maintenance information, the maintenance information transmitted in step B2 is normally transmitted to the hand scanner A and the maintenance is performed as described later. Also means that the maintenance information has been executed (step B4). And the modified PLU file F
It is determined whether or not all the data of B has been transmitted (step B5). As a result, if the transmission has not been completed, the process returns to step B1 to continue the transmission of the maintenance information. When the transmission is complete, send a transmission end signal (step
B6), end.

Next, the interrupt reception process in the hand scanner A
Description will be given with reference to the drawings.

When data is transmitted from the repeater B together with the interrupt request signal, the CPU 15 of each hand scanner A receives the data (step A1) and determines the type of the interrupt request signal (step A2). Then, the interrupt process according to the type is executed.

That is, if it is an interrupt request signal for maintenance, it is judged whether or not the hand scanner A is in a state of waiting for an interrupt reception of maintenance information within a predetermined time (step A3), and the maintenance information interrupt is received. If the status does not wait for the reception of the incoming message, it means that the data just received is the first maintenance information (the bar code of the first record of the modified PLU file FB and the modified unit price), as described later. Therefore, start the unit price rewrite interrupt job (step A4).

On the other hand, when it comes to the state of waiting for the interruption reception of the maintenance information, it instructs to execute the next process in the unit price rewriting interruption job (step A5).

Next, the unit price rewrite interrupt job in the hand scanner A will be described with reference to FIG.

Upon receiving the maintenance information and the interrupt request signal from the repeater B, the CPU 15 of each hand scanner A performs the following interrupt processing.

That is, the unit price change processing flags of all the products in the PLU file FA are set (step A21), and the unchanged flag indicating that there is a product whose unit price has not been changed is set (step A22). Then, the record in the PLU file FA corresponding to the bar code received in step A1 of FIG. 6 is read out and stored in the work area (step A23). Then, the unit price in the record is rewritten to the received changed unit price (step A24), and the unit price change unprocessed flag is reset (step A25). Then, the contents of the record rewritten in the work area are overwritten in the corresponding area in the PLU file FA to be cleared (step A26).

Next, wait for the maintenance information interrupt reception (Step A2
7) When the maintenance information is received by interruption, it is judged whether or not it is a transmission end signal (step A2).
8). As a result, if it is not the transmission end signal, step A
Returning to 23, the unit price rewriting process is continued. If the signal is a transmission end signal, all the unit price change unprocessed flags in the PLU file FA which are still set are reset (step A2
9) Then, the unchanged flag indicating that there is a product whose unit price has not been changed is reset (step A30), and the unit price rewrite interrupt job is ended.

As is clear from the above description, the waiting for the interruption reception of the maintenance information in step A27 is executed after the unit price of at least one product is changed. Therefore, if it is determined in step A3 in FIG. 6 that the interrupt reception waiting state has not been reached within the predetermined time, it means that the maintenance information related to reception is the first information. In step A4, the unit price change interrupt job shown in FIG. 7 is started. When it is determined in step B3 in FIG. 5 that the waiting state for the interrupt reception has not been reached within the predetermined time, the hand scanner A is removed from the relay device B,
Since this means that the maintenance information has not been correctly transmitted to the hand scanner A, the procedure returns to step B1 in FIG. 5 and the maintenance information is retransmitted.

Next, the registration process of the hand scanner A will be described with reference to FIG.

It is assumed that this registration process is performed while not being connected to the repeater B.

Whenever a bar code is entered, the PLU file FA is searched for a record corresponding to the entered bar code (step A41), and it is determined whether or not the unit price change unprocessed flag of the product is set. Yes (Step A4
2). As a result, when the unit price change unprocessed flag is set, the unit price of the corresponding product has not been rewritten to the changed unit price, so the number of works in one registered memory MA is incremented by "1" and the input is made. Only the barcode is registered in one registration memory MA (step A43). And PLU
Increment the number of sales under change of the corresponding product in the file FA by "1" (step A44), and finish.

On the other hand, when the unit price change unprocessed flag of the product corresponding to the input barcode is reset, as usual,
The total sales quantity and the total sales price of the corresponding products are updated in the PLU file FA (step A45), the barcode and unit price are registered in one registration memory MA (step A46), and the processing is ended.

Next, when the registration process for one registration by the hand scanner A is completed and the hand scanner A is connected to the relay device B, the receipt print command process of the hand scanner A is performed.
This will be described with reference to FIG.

When the receipt key 2b is operated in the state of being connected to the repeater B, the CPU 15 of the hand scanner A first determines whether or not the unmodified flag is set (step).
A51). As a result, if the unchanged flag is set, it is determined whether the number of works in one registration memory is "0" (step A52). As a result, if the number of workpieces is not “0”, it means that there are some products that should be printed on the receipt that should have their unit price changed but the unit price has not been changed yet. PLU
Search the products in the file FA for which the number of changed sales is "1" or more and read only one record to the work area (step
A53), the unit price of change of the product is inquired to the repeater B, and the unit price of change obtained by the inquiry is overwritten on the record in the work area (step A54). Then, the number of sales under change is subtracted from the number of works in one registration memory MA (step A55), and for the record in the work area,
The total sales amount is updated based on the changed sales quantity and the changed unit price (step A56), then the changed sales quantity is added to the total sales quantity, and the changed sales quantity is cleared (step A57). Then, the unit price change unprocessed flag is reset (step A58).

Next, the contents of the record that has been rewritten in the work area are overwritten in the corresponding area in the PLU file FA and cleared (step A59). Then, the modified unit price is inserted next to the corresponding bar code in one registered memory MA (step A60), and the process returns to step A52.

If it is determined in step A51 that the unchanged flag has been reset, and if it is determined in step A52 that the number of workpieces is "0", then the process proceeds to step A61, and the receipt print command signal is sent. , 1 transmits the contents of the registered memory MA to the repeater B.

In the repeater B, when the content of the one registration memory MA is received from the hand scanner A together with the receipt print command signal, the receipt printing unit B1 prints the content of the one registration memory MA and issues a receipt. Process.

Further, the hand scanner A waits for an interruption reception of the maintenance information if there is a product for which the unit price change has not been made at the time of issuing the receipt printing command. On the other hand, the repeater B shifts to the flow of FIG. 5 after issuing the receipt, and responds to the interruption reception waiting of the maintenance information of the hand scanner A, and changes the unit price of the product for which the unit price has not been changed yet. To send.

Thus, in the hand scanner A, when the first changed unit price is received, the unit price change unprocessed flag is set for each product in the PLU file FA, and the unit price for the rewritten product is rewritten to the changed unit price. Reset unmodified flag. When the hand scanner A is removed from the repeater B and the scanning operation is performed before all the changed unit prices are received from the repeater B, and the bar code of the product that has not been rewritten for the unit price change is input. , The input quantity is provisionally registered as the sales quantity under change, and for the provisionally registered products, when the hand scanner A is connected to the repeater B, the unit price of the change is inquired to the repeater B and rewritten, etc. Process. Therefore, even when the unit price is being rewritten, the scanning by the hand scanner A can be executed without causing any trouble.

The invention is not limited to the above-mentioned embodiment,
For example, before sending the modified unit price by the relay machine,
The hand scanner may transmit a signal to start the transmission of the changed unit price, and the hand scanner may set the unit price change unprocessed flag of all the commodities when the signal is received. Alternatively, the PLU data may be directly supplied from the head office register C without providing the relay device B. Further, it can be applied to a data processing device other than the electronic register, such as a personal computer or an office computer.

[Effect of the Invention] According to the present invention, even if the preset data regarding the classification data in the terminal is being changed, the classification data is input by the terminal and the preset related to the classification data is changed. The data can be processed based on the data, the customer does not have to wait for a long time for the change processing, and the processing efficiency is improved.
