It connects to a second access point 43 different from the first access point 42. Normally, X-ray imaging information including patient information is communicated between the hospital network 100 and the first access point 42 connected to the hospital network 100. Therefore, when the maintenance computer 102 is connected to the first access point 42 connected to the hospital network 100, there is a risk of leakage of patient information to the maintenance computer 102. According to the mobile X-ray imaging apparatus according to the present invention, the maintenance computer 102 is not connected to the first access point 42 connected to the hospital network 100, but to the first access connected to the hospital network 100. By connecting to the second access point 43 different from the point 42, the usage history of each part of the device is transmitted to the maintenance computer 102 without risk of leakage of patient information to the maintenance computer 102. It becomes possible.
