Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a portable data terminal device used in, for example, route sales, store inventory, and the like, and particularly to data for a card type external storage device such as an IC card. The present invention relates to a portable data terminal device that enables input.

[Technical Background of the Invention and Problems Therefor] A portable data terminal device conventionally used for inventory of stores such as route sales and supermarkets has a key-in content from a keyboard or a content read from a barcode. Is stored in an internal storage device such as RAM, and the stored contents are read into a central computer through a communication line such as RS232C to perform data aggregation processing.

However, in this type of portable data terminal device, when the amount of data of the contents of the key-in from the keyboard or the contents read from the bar code becomes enormous, the RMA, which is the internal storage device, has a capacity to store such data. There is a limit, and it is impossible to follow the increase in stored data. In addition, since the communication line is connected and the data is read from the terminal device each time the central computer performs the data totalization process, the portable data terminal device that requires the data totalization process. However, if the number of data is large, it is very difficult to handle, even though it is portable, and it takes a considerable amount of time to process the data. In such a situation, in most fields of use such as route sales and store inventory, the data read time from the portable data terminal device to the central computer tends to be concentrated, especially in the case of route sales. For example, since the salesmen return to their offices almost at the same time and it is necessary to process the data in a short time even for inventory, it is inevitable that the data aggregation process will be concentrated, and the problems described above will become noticeable. It is the actual situation.

[Object of the Invention] The present invention has been made to solve the above problem, and its object is to increase the storage capacity by following the increase in the number of data and exchanging the storage capacity with a non-input card. (EN) It is possible to provide a portable data terminal device capable of inputting data to an external storage device, which facilitates handling at the time of data aggregation processing by a central computer and shortens time.

[Summary of the Invention] In order to achieve the above object, according to the present invention, a display unit provided at one end of a main body case, a keyboard unit provided in the vicinity of the display unit, and at least a main body case provided therein. In a portable data terminal device comprising a CPU, an internal storage device, a power supply and various control units, a card reading / writing unit is provided at the other end of the main body case in proximity to the keyboard unit, and the card reading / writing unit is at least

When it is ON, it changes to a secret key-in message. This secret key-in message may be necessary or unnecessary depending on the purpose of use. For example, in the case of money receipt, the secret key-in message is used for confirming that the correct card is written. In this example, the case where it is not necessary will be omitted and the case will be described.

Next, it is confirmed that the power supply of the I / F control unit 11 in FIG. 1 is turned on to start communication control, and then the communication circuit with the IC card 22 is connected. Next, the password key-in is accepted, and this is collated with the password inside the card. Then, as a result of this collation, if the two do not match, the secret key-in message is returned, and if the two match, the message indicating that data is being written is displayed, and the data is actually written subsequently.

Next, it is determined whether or not an error has occurred during the data writing, and if an error occurs as a result, the power of the I / F control unit 11 is turned off and an error message is displayed. When ending here, it is ended by pressing the end key 18, and when writing is redone, the key 17 is pressed again to return to the card set message and try again. On the other hand, when it is determined that the error does not occur in the above, it is determined whether or not the data has ended. If the result is that there is data, the data is written again, and if the data has ended, the I / F controller 11 Turn off the power of and turn off the write completion message. After that, by pressing the end key 18, the writing is completed, and by the above operation, the writing of the data to the IC card 22 is completed.

In the above, the case of writing data to the IC card 22 is described, but it is also possible to read data from the IC card 22. In this case, the second
