  Next, the operation of the embodiment of the present invention configured as described above will be described with reference to the flowcharts of FIGS. First, the manager inputs from the master management terminal 3 inspection information on which parts and parts are to be inspected in each process for each manufactured automobile. As a result, the inspection information is transmitted to the inspection master database 11 of the server 2 as an inspection job.

 Next, the inspection portable terminal 5 displays an inspection screen on the liquid crystal display 54 based on the inspection job transmitted from the server 2 (step S1). And the inspection result of each process is inputted into the inspection screen.

  That is, an “NG” button and an “OK” button as specific buttons are provided for each inspection item on the inspection screen.

The operator inspects the inspection target part displayed on the inspection screen. If it is determined that there is no problem as a result of this inspection, the operator presses the “OK” button. If it is determined that there is a problem as a result of the inspection, the operator clicks the “NG” button.

  In step S2, it is determined whether the “NG” button has been pressed. When the operator operates the “NG” button, “YES” is determined in the determination in step S2, and the process proceeds to step S3. In this step S3, an inspection phenomenon input mode screen as a specific input screen is displayed on the liquid crystal display 54 of the inspection portable terminal 5.

  On the screen of the test phenomenon input mode, data such as test target, test content, test site, reference, measurement value, and the like are displayed, and a test phenomenon registration window for registering the test phenomenon is displayed. In this inspection phenomenon registration window, an inspection phenomenon, an inspection site, an occurrence state, a handwritten memo, and points (those where the occurrence portion is indicated by points) are displayed. The inspection phenomenon, inspection site, and occurrence status are coded. The specific contents of the inspection phenomenon are listed in the window as candidates for the inspection phenomenon. For example, “−”, “large”, “small”, “adjustment failure”, and “not adjusted” are listed as inspection phenomena. “−” Is a case that does not correspond to “many”, “small”, “adjustment poor”, and “not adjusted”. In addition, candidates for examination sites are listed in this window. In this embodiment, only “-” is displayed in the window. This means that the candidate for the examination site is not listed.

  Furthermore, candidates for occurrence status are listed in another window. For example, “-”, “secondary inspection”, “E / G start-up”, etc. are listed.

  The operator selects the contents corresponding to each item (inspection phenomenon, inspection site, occurrence status,...) Of the inspection phenomenon registration window from the candidates displayed in the above-mentioned window, and presses the add button to select the inspection phenomenon. I am trying to register.

  That is, it is determined whether the add button has been pressed (step S4). If it is determined that the add button has been pressed, the test information (test phenomenon, test site, occurrence status) is input to the test phenomenon registration window. In this way, a plurality of coded examination information can be set by pressing the add button.

  By the way, an input button for inputting a handwritten memo and an input button for inputting an inspection point are displayed at the center on the right side of the screen in the inspection phenomenon input mode.

  Further, a part image list for inputting inspection points is displayed below the input button. From this list, select the part of the vehicle on which the image is to be displayed, such as “MPI E / G”, “front”, “right rear”, and so on. When that part is selected in this list, a request is output so that the server 2 transmits the specified component image. The part image transmitted from the server 2 in response to this request is displayed.

  That is, it is determined whether the inspection point input button has been pressed (step S6). If "YES" is determined in the step S6, the inspection point input screen 70 on which the part image of the part selected in the part image list is displayed is displayed as shown in FIG. 8 (step S7).

  Then, the operator inputs an inspection point on the inspection point input screen 70 with a touch pen or the like. Then, it is determined as “YES” in step S8 in which it is determined whether or not the inspection point has been input, the inspection point is displayed with “×” mark, and the coordinates of the inspection point are stored in the RAM 53 (step S9).

  Next, it is determined whether the OK button 71 has been pressed (step S10). If the operator does not press the OK button 71, “NO” is determined in the step S10, so that the process returns to the step S7 and another inspection point can be input again. That is, a plurality of inspection points can be input for one inspection item.

  On the other hand, when the operator presses the OK button 71, it is determined as “YES” in the step S10, so that the process returns to the above-described step S3.

  By the way, when it determines with "NO" in step S6, it is determined whether the handwritten memo input button was pressed. When the operator presses the handwritten memo input button, a handwritten memo input screen 73 as shown in FIG. 9 is displayed and their image data is stored in the RAM 53 (step S12).

  Then, the operator inputs a drawing of a nut, for example, by pen input, and describes the location where the inspection has occurred by “→”.

  Then, it is determined whether the OK button 74 has been pressed (step S13). If it is determined as “YES” in step S13, the process returns to the above-described step S3, and the examination input display screen is displayed.

  Then, the process proceeds to step S4, and if the add button is not pressed, it is determined as “NO” in this step S4 and it is determined whether the registration button is pressed (step S14). If "YES" is determined in the process of step S14, the inspection information is transmitted to the server 2 (step S15). The inspection information includes inspection information input from the inspection input display screen, information on inspection points input from the inspection point input screen 70, and information on the handwritten memo input screen 73. All the inspection information input from the inspection input display screen is coded information.

  By the way, the server 2 determines whether or not there is a request for transmitting the component image from the inspection portable terminal 5 (step S21). And when it determines with "YES" by this step S21, a components image is transmitted to the portable terminal 5 (step S22).

  Further, it is determined whether the inspection information transmitted from the portable terminal 5 has been received (step S23). If "YES" is determined in the step S23, the inspection information for each inspection item is stored in the inspection result database 12 (step S24).

  As described above, the inspection is stored as a code for each inspection item, and the point where the inspection has occurred is designated with a point on the image data so that it can be visually understood. On the other hand, by transmitting these pieces of information, it is possible to smoothly rework the process.

  Furthermore, since the inspection location can be input by handwriting for each inspection item, it is possible to accurately store the inspection location that is more difficult to understand.

  In the above embodiment, the request for transmitting the component image is output from the inspection portable terminal 5 to the server 2. However, the present invention is not limited to this, and the component image data is stored in the inspection portable terminal 5. By doing so, it is not necessary to output a transmission request to the server 2.

  Further, in this embodiment, the inspection mobile terminal is used as the inspection terminal and communication is performed by the wireless communication method via the server 2 and the access point 4, but the present invention is not limited to this. 2 and an installation type inspection terminal set by the LAN may be used.
