The purpose of the present invention is to provide a barcode interface holding device that can easily read magnetic card data, and includes a photoelectric conversion means for scanning a barcode to obtain an optical signal as barcode data, and a means for reading magnetic card data. and a data conversion circuit for converting the magnetic card data read by the reading means into barcode data, and a switching means for selectively switching between the data converted by the data conversion circuit and the data input by the photoelectric conversion means. It is configured to have the following.

[Industrial Application Field] The present invention relates to a barcode interface holding device having a magnetic card reading function.

[Conventional technology]

In recent years, in supermarkets and the like, product name code numbers, prices, etc. are displayed in the form of stick-shaped barcodes, which are printed on foods, miscellaneous goods, etc., or attached as labels. In industries that process a large number of shopper sales in a short period of time, this barcode is read by a barcode reader and the information recorded there is used for various purposes such as point-of-sale management. . The barcode reading device has, for example, a barcode pen, a barcode interface holding device, etc., and uses an electric signal obtained by scanning a barcode with the barcode pen to read the barcode according to the bar width via the barcode interface holding device. Then, the wide and narrow widths of the black and white bars are sequentially detected using threshold values, and the bit pattern is determined and demodulated into characters and the like. There is a demand for adding a magnetic card reading function to a device having such a barcode interface so as to read the personal identification number of the magnetic card, for example, and process the data together with the barcode data. In this case, it was necessary to provide a new magnetic card interface.

[The problem that the idea aims to solve]

However, in conventional devices with barcode interfaces, adding a magnetic card reading function requires program changes and major changes to connectors, etc., and there is a problem that it cannot be easily added.

This idea was created in view of the above circumstances.
To provide a barcode interface carrying device capable of adding a magnetic card reading function to the barcode interface carrying device without requiring major changes and easily reading magnetic card data.

[Means for solving the problems]

The above problem is solved by a photoelectric conversion means such as a barcode pen that scans a barcode and obtains an optical signal as barcode data, a magnetic card data reading means such as a magnetic card reader, and this reading means. It includes a conversion circuit that converts input magnetic card data into barcode data, and has switching means such as a changeover switch that selectively switches between the data converted by the data conversion circuit and the data input by the photoelectric conversion means. This problem is solved by a barcode interface holding device characterized by the following.

[Effect]

In the present invention, the magnetic card data read by the reading means is converted into barcode data by the data conversion circuit, and the switching means switches between the converted data and the barcode data input by the photoelectric conversion means. There is no need to change the program or connector on the main body of the barcode interface holding device.

Therefore, a magnetic card reading function can be added to the barcode interface carrying device without making any major changes.

Next, the conversion operation of the data conversion circuit of the present invention will be explained.

FIG. 3 is an operation flowchart of the data conversion circuit. In the figure, data is first read from the magnetic card (step ST1). Next, the conversion table is referred to based on the data read from this magnetic card. (Step ST2). As shown in FIG. 4, this conversion table is a table in which barcode formats are stored at addresses corresponding to magnetic card output. This barcode format is, for example, combination data in which the bar widths of a black bar and a white bar constituting a character code corresponding to magnetic card data are changed over time. Next, a barcode format with the corresponding magnetic card data as an address is read from the conversion table (step ST3). The barcode format data converted by this data conversion circuit is given to the barcode interface holding device main body 6 via the changeover switch section 4.
