  Next, the matching unit 208 of the site specifying unit 206 initializes the initial site number variable N to 1. In step S22 (an example of the part specifying step), the matching unit 208 compares the received captured image with the image of the part N stored in advance, and determines whether or not the two images match. . Here, it is determined whether or not both images match based on the feature of the edge of the part N and the feature of the luminance distribution, but it is determined based on the feature of the edge of the part N or the feature of the luminance distribution. Also good.

  If the two images do not match, the matching unit 208 adds 1 to the part number variable N in step S23, returns to step S22, and repeats the same processing. If the two images match, the matching unit 208 sets the part number to N, and proceeds to step S24.

  In step S24, the size measuring unit 210 of the site specifying unit 206 measures the size of the site in the image and determines the size of the site with respect to a predetermined threshold. If the ratio of the part to be imaged in the image is large, select a more detailed manual. Conversely, if the ratio in the image of the part to be imaged is small, the unit including that part is selected. Select the manual.

  Specifically, the size measuring unit 210 measures the ratio of the part N, which is the object to be imaged, in the captured image and compares it with a predetermined threshold value. For example, it is determined whether or not the ratio of the part N is 50% or more of the area of the captured image.

  If it is smaller than the threshold value, that is, if the part N is photographed away from the ink jet recording apparatus 10, the part number variable is set to the part in step S25 assuming that the requested manual is the manual of the unit including the part N. The unit number is changed to N, and the process proceeds to step S26. On the other hand, if it is equal to or greater than the threshold value, that is, if the part N is photographed close to the inkjet recording apparatus 10, it is determined that the requested manual is the manual for the part N, and the process proceeds to step S26.

  For example, if it is the image image | photographed close to the communication connector mounted in the electric substrate, it will determine with a site | part being a communication connector. Further, when other parts are also reflected around the communication connector, it is determined that the part is a connection portion between the electric board and the communication connector and other parts. By determining the size of the part in this manner, when the part is determined to be a communication connector, the specification of the communication connector is displayed, and the part is a connection part between the electric board and the communication connector and other parts. When the determination is made, the manual selected depending on the size of the part can be varied, such as displaying a connection diagram of the communication connector.

  Subsequently, the part specifying unit 206 stores the state information received from the tablet 130 in the state number variable S in step S26.

  Next, the requester specifying unit 212 of the part specifying unit 206 confirms the requester information received from the tablet 130 in step S27. If the requester is a serviceman of the manufacturer of the inkjet recording apparatus 10, the process proceeds to step S28, and if the requester is an operator who operates the inkjet recording apparatus 10, the process proceeds to step S29.

  In step S <b> 28, the selection condition analysis unit 204 stores the manual number for the serviceman with the part number N and the state number S in the manual number variable M. On the other hand, in step S29, the selection condition analysis unit 204 stores the manual number for the operator of the part number N and the state number S in the manual number variable M. Both step S28 and step S29 shift to step S30.

  In step S30, the selection unit 214 selects the manual data with the manual number M from the manual data 218 of the manual database 216, and transmits it to the tablet 130 via the communication unit 202 (an example of a manual transmission unit). The manual with the manual number M is a manual related to the manual selection condition received in step S21.
