However, the inspection apparatus of the present invention can collectively manage inspection results and product information by connecting a personal computer to a network. Become. FIG. 9 shows an embodiment of a network configuration using the inspection apparatus of the present invention. In this embodiment, a state is shown in which a plurality of inspection stations corresponding to each inspection item are connected by a network, and each station may be in the same work place or may be completely separated. One station may correspond to a plurality of inspection items.

In such a network configuration, products are managed by product serial numbers, and all inspection results at each station are stored in the database of the network server 901.

For example, when a product is brought into the faulty product receiving station 902, the contents of the report of the fault and the result of the diagnosis at the time of receiving are written together with the product serial number. The data written by the station 902 is sent to the network server 901 and becomes a part of the database. In this station 902, products are classified into items to be inspected according to the contents of the declaration and the contents of the diagnosis at the time of receipt.
For example, depending on whether power system inspection or audio system inspection is required, the station
Convey to 3-905. In each station, the inspection apparatus shown in FIG. 1 is installed, and replacement parts corresponding to the inspection items are prepared. Here, the measurement is started according to the procedure shown in FIG. In this case, if the inspection item (inspection group) is determined by the station, steps 603 to 610 are executed without setting them in step 602. When filling out the report,
Since the contents of the report and the contents of the acceptance diagnosis among the contents of the report are filled out by transferring data from the database, the report can be made by filling in other necessary items.

When the inspection is completed at one station, the result is sent to the database of the server via the network and becomes a part of the database. Therefore, for one product controlled by the product serial number, the results of previous inspections and repair records are stored, and this data can be stored at another station or a remote station 906 connected to the same network connected to the same network. Can also be referenced.

Although the above embodiment has been described with reference to an example of an inspection apparatus in a repair process of a mobile phone, the present invention is not limited to a mobile phone and is applicable to an inspection apparatus of an electronic device requiring a plurality of inspections. it can.
