When the weighing machine 10 receives a maintenance code from the portable data input / output device 20 and inputs a maintenance key using the operation unit 12 (ST3), the weighing machine 10 shifts to a maintenance mode (ST4). After confirming the reception key 25, the error log data stored in the control device 15 of the weighing machine 10 is transmitted from the transmission unit 13 to the portable data input / output device 20 (ST5). The portable data input / output device 20 receives the error log data transmitted from the weighing machine 10 by the receiving unit 22 under the control of the data control unit 30 (ST6), temporarily stores it in the memory 27, and displays it. The data is displayed on the device 28 and recorded on the medium 32 by the reader / writer 31 (ST7). When all the error log data has been transmitted, the portable data input / output device 20 finishes receiving (ST8), and the weighing machine 10 side also ends the maintenance mode by this end (ST9).
[0014]
Subsequently, the medium 32 on which the error log data is recorded is extracted from the reader / writer 31 of the portable data input / output device 20, read by a personal computer terminal installed in a gas station, and transmitted to a maintenance company or the like. It is also possible to connect the data transmission unit 29 of the portable data input / output device 20 to a personal computer terminal via a wired cable, read the error log data recorded in the memory 26 or the medium 27, and send it to the maintenance company. The maintenance company that has received the error log data can quickly take action by analyzing the contents and informing the gas station of the countermeasures.
[0015]
In the portable data input / output device 20 having the above-described configuration, the portable case main body 21 has transmission / reception units 23 and 22 for transmitting / receiving data to / from devices such as the weighing machine 10 installed in the gas station, and data transmission / reception. Transmission / reception keys 24 and 25 for performing the above operations, a numeric keypad 26 for inputting variable setting data, a display 28 for displaying data, and a medium 32 for recording fixed setting data and error log data of the device. By providing a reader / writer 31 for reading and writing and a data control unit 30 for controlling each unit, when initial setting of a device such as the weighing machine 10, fixed setting data among the setting data is recorded in the medium 32 in advance, When the initial setting work is performed, the fixed setting data is read from the medium 32 by the reader / writer 31 and the variable setting data is input by the ten key 26, thereby transmitting and receiving. When the key 24 is operated, the setting data is transmitted from the transmission unit 23 to the device for registration, and when maintenance work is performed, error log data is received from the device from the reception unit 22 by the operation of the reception key 25 and is read by the reader / writer 31. Since the data is recorded on the medium 32, the initial setting data registration work can be simplified, and the maintenance work can be quickly handled because the error log data on the medium 32 can be transmitted to a maintenance company for analysis.
[0016]
In the above embodiment, it is only necessary that data can be transmitted and received between the portable data input / output device 20 and the weighing machine 10 by using radio waves or light such as ultraviolet rays. Moreover, although the example which used the identification number which identifies the weighing machine 10 in transmission / reception was demonstrated, the directivity of the transmission parts 13 and 23 and the receiving parts 14 and 22 of the weighing machine 10 and the portable data input / output device 10 is narrowed. By doing so, it is possible to prevent interference even at a gas station where devices such as a plurality of weighing machines 10 are arranged.
