Abstract

PURPOSE:To use an information reading device such as a scanner, for plural purposes at a same time by controlling reading information to be given to either a first processing means or a second processing means on the basis of the instruction of an instructing means when the information to be needed for processing are read by a reading means. CONSTITUTION:For example, when a commodity code, which is read by a scanner 1 and corresponds to a bar code, is not set to a RAM 10, such a condition is discriminated as an error and error display is executed by a CRT display 7. When the error display is not executed, normal registration processing is executed. When there is a commodity to be next registered and processed, the bar code of the commodity is read by the scanner 1 and the registration processing is continued. When there is not commodity to be registered and processed, a total sum key to be provided in a keyboard 6 is pushed down and a sales total amount is operated. Then, a receipt is issued by a printer continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing device, and particularly to a data processing device that can simultaneously use information read by a reading means for a plurality of purposes.

[Conventional technology] As everyone knows, supermarkets etc. have P.

S (point of sales) system was installed,
Sales information at the time of sale is immediately processed by a computer. When performing sales processing, the store operator sets the POS terminal device to registration mode and causes the scanner provided in the PO8 terminal device to read the barcode attached to the product. Then, based on the product identification information corresponding to the barcode, the unit price information of the product stored in the memory in advance is read out and registered. If the corresponding product identification information is not stored in the memory, an error message is displayed, and the product identification information and unit price information manually input by the operator are registered. After the store closes, the operator returns to PO8.
The terminal device was set in a setting mode, and necessary information such as product identification information and unit price information for the product was set and stored in the memory using a keyboard or the like.

[Problems to be Solved by the Invention] As described above, while the scanner in the conventional PO8 terminal device is being used for registration processing in registration mode, it cannot be used for setting mode or return processing mode at the same time.

Therefore, a main object of the present invention is to provide a data processing device that allows an information reading device such as a scanner to be used for multiple purposes at the same time.

[Means for Solving the Problems] A data processing device according to the present invention includes a reading device for reading information necessary for processing, and a device for performing a predetermined first process based on the information read by the reading device. a first processing means, a second processing means for performing a second process different from the first process in parallel with the processing of the first processing means, based on the information read by the reading means, and a reading means. When information necessary for processing is read by the reading means, the read information is sent to the first processing means and the second processing means based on the instruction from the instruction means. and a control means for controlling such that it is given to either one of the two.

[Operation] When the reading means reads information necessary for processing, the data processing device according to the present invention transmits the read information to the first processing means if the first processing means is designated as the data destination. and when the second processing means is instructed, the reading information is given to the second processing means.

[Embodiment of the Invention] FIG. 1 is a diagram for explaining an outline of an embodiment of the invention. In FIG. 1, a scanner 1 as a reading means
The barcode is read and the read data is given to the control means 2. The control means 2 supplies the read data to the registration processing means 3 or the setting processing means 4 according to instructions in area b of the RAM 10 in FIG. 2, which will be described later. Specifically, if the registration mode is set, the read data is used for registration processing, and if the setting mode is selected, the read data is used to set the necessary data. It will be done.

Note that the reading means is not limited to a scanner for reading barcodes, and for example, a tag pen reader for reading character information attached to a label of a product may be used. The tag pen reader may be one that reads text information optically or may be one that reads text information magnetically. Further, a data queue 31 (not shown) is provided corresponding to the registration processing means 3, and a data queue 41 (not shown) is provided corresponding to the setting processing means 4. The data is given to the data queue 31, and when the setting mode is selected, the read data is given to the data queue 4.
1 may be given.

FIG. 2 is a schematic block diagram showing the main electrical configuration of an embodiment of the present invention. In FIG. 2, the PO8 terminal device 20 is provided with a CPU5.

The CPU 5 has a keyboard 6, a CRT display 7,
Interface 8. ROM9. RAM10 and 11
is connected. The keyboard 6 includes numeric keys for setting monetary data, various instruction keys for total calculations and payment processing, and a mode changeover switch a for switching operation modes. The CRT display 7 displays a screen corresponding to the registration mode or setting mode. The interface 8 is for providing a read signal from the scanner 1 to the CPU 5.

The ROM 9 stores an operating program for the CPU 5, which is summarized in a flow diagram as shown in FIG. 3, which will be explained later. RAM 10 is for registering sales data, and includes areas in which product name data, department codes, and unit price data are stored for each product code. Further, the RAM 10 is provided with an area b for storing which mode the device is currently in. If the code in area b is 0, it indicates the registration mode, and if it is 1, it indicates the setting mode. RAM II is a work memory and includes an area C for temporarily storing data to be set.

FIG. 3 is a flow diagram for explaining the operation of one embodiment of the present invention. Next, referring to Figures 1 to 3,
The operation of one embodiment of this invention will be explained. Below, we will explain how to load two programs in registration mode and setting mode to perform processing. The registration processing program and the setting processing program are multitasked.

The data read by the scanner 1 is then given to a routine that executes a selected operating mode, that is, a mode corresponding to the screen displayed on the CRT display 7, as will be described later.

When the operator turns on the power of the PO8 terminal device 20, the operator operates the mode changeover switch a to start the registration processing program and the setting processing program. In the PO8 terminal device 20, the registration mode is preferentially selected in step S1, and the code "0" corresponding to the registration mode is R.
It is stored in area b of AMl0 and displayed on CRT display 7.
A screen for registration processing is displayed, and the scanner 1 is in a state of waiting for data input from the scanner 1. Step S2
When a barcode is read by the scanner 1, the product code corresponding to the barcode is given to the CPU 5, and the area of RAM 10 corresponding to the product code is accessed to read product name data, department code, unit price data, etc. Then, registration processing is performed. At this time,
If the product code corresponding to the barcode read by the scanner 1 is not set in RAMl0, it is determined in step S3 whether there is an error, and the CR
An error message is displayed on the T-display 7, and the process advances to step Sll. If no error is displayed, normal registration processing is performed, and if there is a product to be registered next in step S4, the process returns to step S2, the barcode of that product is read by the scanner 1, and registration processing is performed. If there is no product to be registered, the process proceeds to step $5. In step S5, a total key (not shown) provided on the keyboard 6 is pressed, and in step S6, the total amount of sales is calculated, and then in step S
At 7, a receipt is issued by a printer (not shown).

On the other hand, if it is determined in step S3 that an error has occurred and an error display is performed, step S1
1, the operator presses the mode changeover switch a on the keyboard 6. As a result, in step S12, the operation mode is switched from the registration mode to the setting mode. That is, by operating mode selector switch a,
The code stored in area b of RAMl0 is “0”
The display changes from "1" to "l", and a screen display for performing setting processing is displayed on the CRT display 7.

In step 313, the barcode information read by the scanner 1 is read as a code in the setting mode based on the code stored in area b of RAM10. In step 514, the operator inputs missing data for the barcode information, such as product name data, department code, and unit price data, and makes settings in the memory. In step S15, it is determined whether or not the data setting has been completed. If not, the process returns to step S14 and data input is continued; if it has been completed, the mode selection switch a is switched again in step S15.
Operate to switch the operation mode. By switching to the registration mode, the registration process can be performed again.

Note that the data input in the setting mode is
The data stored in area C of RAMII is stored as transaction information for one transaction, and in response to the code "0" being set in area b of RAM10, the data stored in area C of RAMII is read out and sent to the CRT. displayed on display 7. In the subsequent registration process, when the product set in the setting mode is registered, the registration process is performed based on the data set in the setting mode, so there is no need to input the same data again.

Since multitasking is performed, for example, even when a setting operation is performed by interrupting the registration process, the registration process based on the data read before the interruption is performed in parallel with the setting operation.

As described above, in this embodiment, it is possible to simultaneously read the barcode with the scanner for two processes for a transaction, thereby eliminating the need to manually input the necessary data for each transaction as in the conventional case.

[Effects of the Invention] As described above, according to the present invention, the processing by the first processing means and the processing by the second processing means are performed in parallel, and the information necessary for the processing is read by the reading means. If the first processing means is designated as the data destination in accordance with the above, the reading information is given to the first processing means;
Since reading information is given to the second processing means when the second processing means is instructed, the reading means can be used for a plurality of purposes at the same time by switching the instruction as necessary.
