Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data processing method in a data collection device that sequentially receives input data and sequentially stores it in a storage unit.

In recent years, for example, in department stores or supermarkets, various product data for each product is converted into barcode data and displayed, and if necessary, the barcode data is collected by a data collection device and then displayed. Various systems have been developed and put into practical use for managing product inventory by inputting the collected data into a computer or the like and performing predetermined data processing. A data collection device in such a system generally receives barcode data as input data by manually scanning and reading barcode data with a hand scanner, and sequentially stores the barcode data in a storage unit. However, with this type of data collection device, if the number of digits in the barcode data is relatively small (2 to 3 digits), this problem does not occur much.
For example, when reading multi-digit barcode data as shown in Figure 1a, not only is the reading operation using a hand scanner very troublesome due to the large number of digits, but it also takes a long time to input and collect the collected data. Moreover, it becomes difficult to accurately read and scan barcode data, leading to problems such as misreading and data input errors.

The barcode data shown in Figure 1a is, for example, data used for product management as described above, and includes a 2-digit major classification code representing the product type, a 4-digit code representing the product color, etc. They are distinguished by a medium classification code of digits and a minor classification code representing a product code. Therefore,
In barcode data in this format, the minor classification code changes for each product, the medium classification code changes for each product color, and the major classification code changes for each product type. Become.

The present invention has been made in view of the above circumstances, and its purpose is to enable accurate and easy input of collected data even if the data has many digits, significantly improve operator operability, and reduce data collection time. The purpose of the present invention is to provide a data processing method in a data collection device that can shorten the time required and prevent errors in inputting collected data.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 schematically shows the external appearance of, for example, a portable data collection device according to the present invention, in which a belt 2 for carrying over the shoulder is attached to a portable device main body 1. An operating section 3 is provided on the upper surface of the main body 1. A connector section 4 is provided at the left end of the upper surface of the main body 1, and a keyboard input section 7 is connected to the connector section 4 via cables 5 and 6.
and a hand scanner 8 are detachably connected to each other. The keyboard input section 7 includes a keyboard 9 for inputting collected data, etc., and a display section 1 for displaying input data or output data.
0. Further, the hand scanner 8 can be used, for example, by an operator holding it in his hand and manually scanning the barcode data.
This is a well-known method for optically reading the data.
Although not shown in the drawings, the main body 1 houses an input/output control section, a main control section, a storage section, an input memory, a duplex memory, etc., which will be described later.

FIG. 3 schematically shows the overall configuration of the data collection device configured as described above, and is configured as follows, for example. That is, the hand scanner 8 and the keyboard input section 7 are connected to the input/output control section 11.
performs data input/output control. The input/output control section 11 is connected to a main control section 12 .
The main control section 12 controls the input/output control section 11, and also performs data storage control or readout control for the input memory 13, duplex memory 14, and storage section 15, which will be described later. be. The main control section 12 includes an input memory 13, a duplex memory 14, and a storage section 15.
are connected to each other. Above input memory 13
is a register having a capacity of, for example, 8 digits, in which the input data transferred from the main control unit 12 is set in a predetermined digit direction, and the data transferred from the duplex memory 14 is set in a predetermined digit direction. It is. The duplex memory 14 is, for example, a register having a digit capacity of eight lines, the same as the input memory 13, and data transferred from the input memory 13 is set from a predetermined digit direction. Further, the storage section 15 includes an input memory 13
It is used to accumulate (collect) data supplied from Further, a transmission connector 16 is connected to the main control section 12 . This transmission connector 16 is connected to a data processing device or the like that transfers collected data.

Next, a data processing method according to the present invention in such a configuration will be explained in detail. For example, assume that 8-digit barcode data in a format as shown in FIG. 1A is sequentially read and input and collected. First, barcode data of eight digits, which is the standard number of digits shown in FIG. Then, the read data is supplied to the main control section 12 via the input/output control section 11 as input data. The main control unit 12 discriminates the supplied 8-digit barcode data, and transfers the discrimination result to the input memory 13 and sets it therein. As a result, the contents of the input memory 13 become as shown in FIG. 4a. After setting the input data in the input memory 13, the main control unit 12 determines that the data in the input memory 13 has a predetermined number of digits (8 digits in this case).
Check the input data to see if it is accurate and correct. As a result of the check, if the data is correct, the data in the input memory 13 is transferred to the storage unit 15.
The data is transferred to and stored there, and also transferred to the duplex memory 14 and set there. As a result, the contents of the duplex memory 14 and the storage section 15 become as shown in FIG. 4b. Note that at this time, the data in the input memory 13 may be erased at the same time as the transfer, or may be left as is without being erased.

After inputting the eight-digit barcode data, which is the standard number of digits, thereafter, only the digit data that changes for each data is input sequentially. That is,
Generally, this type of barcode data consists of a major classification code, a medium classification code, and a minor classification code, as described above, and all digits do not change for each data, but only the minor classification code changes for each data. However, the other intermediate classification codes and major classification codes change for each predetermined number of data groups.
Therefore, in this case, the actual barcode data is 8 digits as shown in Figure 1B by broken lines and solid lines, as in Figure 1A, but for example, if only the minor classification code changes, Only the lower two digits of data shown in solid lines in FIG. 1b are read and input. Now, when the two-digit barcode data (minor classification code) shown in FIG. Ru. The main control unit 12 discriminates the supplied two-digit barcode data and stores the discrimination result in the input memory 13.
and set it in the lower two digits. As a result, the contents of the input memory 13 become as shown in FIG. 4c. At this time, the contents of the duplex memory 14 and the storage section 15 are the same as in the state shown in FIG. 4b. After setting the input data in the input memory 13, the main control unit 12 confirms that the data in the input memory 13 is less than or equal to a predetermined number of digits (in this case, 8 digits or less), and sets the data at the time of data setting. For the digits of the input memory 13 (from the 3rd digit to the 8th digit) that have not been set, as shown in FIG. 4d,
By transferring data from each digit (from the 3rd digit to the 8th digit) of the duplex memory 14 corresponding to each digit, the data in the input memory 13 is completed into actual 8-digit data. As a result, the contents of the input memory 13, duplex memory 14, and storage section 15 become as shown in FIG. 4d. Note that at this time, the data in the duplex memory 14 is
It may be erased at the same time as the transfer, or it may be left as is without erasing. When the data in the input memory 13 has been completed into 8-digit data, the main control section 12 performs the same input check as described above. If it is correct, the data in the input memory 13 is transferred to the storage unit 15 and stored there,
The data is also transferred to the duplex memory 14 and its contents are updated. As a result, the contents of the duplex memory 14 and the storage section 15 become as shown in FIG. 4e.

In this way, by sequentially inputting only the lower two digits of data, the input data becomes the actual 8
The digit data is completed and sequentially stored in the storage unit 15. Then, after collecting a predetermined number of data groups, if the middle classification code changes next time, enter only the lower 6 digits of data here, and then enter only the lower 2 digits of data again sequentially. ,
As above, the data is completed into 8 digits and stored in the storage unit 15.
The information is accumulated sequentially. Note that if 8-digit data, which is the standard number of digits, is input midway through, the process returns to the same operation as above and repeats the above operation again.

When 8-digit data, which is the standard number of digits, is input, it is transferred to the input memory 13, set, and checked for input.If the data is correct as a result of the check, the data in the input memory 13 is transferred. is stored in the storage unit 15 and transferred to the duplex memory 14 having the same digit capacity as the input memory and set therein.
When data for a digit is input, it is transferred to the input memory 13 and set from the lower digits, and for each digit in the input memory 13 for which data was not set at the time of data setting, the corresponding digit is set. By transferring data from each corresponding digit of the duplex memory 14, the data in the input memory 13 is completed to the standard number of digits, that is, actual 8-digit data, and this completed data is stored in the storage section 15 and transferred to the duplex memory 14. 14 and is set (updated).

Therefore, according to such a data processing method, the following various effects can be obtained. In other words, even if the barcode data to be collected has many digits, if you first input the standard number of digits data, you only need to input the digit data that changes after that. The number of digits is much smaller than the actual number of digits, which not only greatly simplifies the reading operation with a hand scanner, but also reduces the time required to input and collect data. Furthermore, since the number of digits in the barcode data is small, it is not only extremely easy to print the barcode data and display it on products, but also it is possible to read and scan the barcode data accurately.
Therefore, it is possible to input data accurately without causing misreading.

As described in detail above, according to the present invention, even if the collected data has many digits, it is possible to input the data accurately and easily, significantly improving operability for the operator, shortening the data collection time, and It is possible to provide a data processing method in a data collection device that provides various effects such as preventing data input errors.
