When a trouble occurs next time, a change function processing unit (corresponding to a change unit) 10f of the control device 10 that changes the priority of data presentation by the display function processing unit 10b according to the corrected priority is provided. This is different from the first embodiment in the point. Further, the present apparatus has a data storage unit (corresponding to a second memory) 10c for storing error storage data D5 which is history data of data correction by the input unit 12, and a display for presenting the stored error storage data D5. A function processing unit (corresponding to a second presentation unit) 10b may be provided, and this is also different from the first embodiment. The input unit 12, the data storage unit 10c, and the display function processing unit 10b of the apparatus
Although the input unit 12, the data storage unit 10c, and the display function processing unit 10b of the device 1 are also used for simplification of the device, they may be provided separately.

FIG. 13 shows an example of screen output by the display function processing unit 10b. By switching the function of the error cause correction screen of FIG. 8 as shown in FIG. 13, the operator can freely change the data presentation order by selecting the presentation order of the data correction screen with the cursor key of the input unit 12.

In this case, when an error occurs during the production of the mounting board, as shown in FIG. 1 and FIG. 6, related data considered to be the cause of the recognition error is displayed by the display function processing section 10b. The data is displayed on the unit 11 and the operator inputs the data D7 to be corrected from the input unit 12 while viewing the data. Based on the input data D7, the data management function processing unit 10a searches the data structure of the operation data D0 shown in FIG. 7 for relevant data, and stores error correction data D5, which is correction history data. Is stored in the data storage unit 10c of FIG. The error storage data D5 is stored in the display function processing unit 10 in the same manner as the operation data D0.
b can be displayed on the display unit 11. Then, when the same error occurs next time, the operator refers to the error storage data D5 and corrects the data to determine the priority of the display of the corrected data.

As described above, according to the present apparatus, the operator can arbitrarily select the priority of data presentation. For example, the operator can preferentially present data that causes a recurring error. In addition, it is possible to quickly and accurately take measures against errors that are likely to occur inherent in the apparatus.

Further, the operator can refer to the error storage data D5 and select the priority order of the data presentation. In this case, for example, the data causing the repeatedly generated error is objectively determined. By grasping and presenting the information preferentially, it is possible to more quickly and accurately take measures against errors that are likely to occur unique to the apparatus.

In the apparatus shown in the first and second embodiments, the recognition error of the electronic component is exemplified as the trouble of the apparatus main body 1 which occurred during the production of the mounting board. The same measures can be taken for other errors that may occur during operation.

In addition, data correction for trouble
Although the operator performs the operation manually, the data can be automatically restored by providing the actual data accumulated as the error storage data D5 in the data storage unit 10c in FIG. 7 and an appropriate judgment program. In the apparatus according to the second embodiment, the operator manually selects the priority order of data presentation, but the data storage unit 10c in FIG.
By providing the result data stored therein as the error storage data D5 and an appropriate second determination program, it is also possible to automatically select the priority order of data presentation.

Further, the data management function processing unit 10a, the display function processing unit 10b, the update function processing unit 10d, and the change function processing unit 10f of the control device 10 are each embodied by an executable program built in the same device. Be transformed into However, some or all of them may be replaced with hardware. In addition, the data storage unit 10c of the control device 10 is embodied by an internal memory of the device and an external storage device.
