PURPOSE:To update an EDR to a new EDR after confirming that a failure never increases by executing two types of operations, which are the operation of the EDR up to this time and the operation of the new EDR, comparing the operation results, and updating the EDR up to this time to the new EDR after sufficiently evaluating the reliability of the new EDR. CONSTITUTION:When the EDR up to this time is to be updated to the new EDR, while the operation based on the EDR used up to this time is performed in first operation parts, the operation based on the new EDR is performed in second operation parts 4c and 4c'. The operation result in the first operation parts 4b and 4b' and that of the second operation parts 4c and 4c' are displayed on display parts 4d and 4d' and compared with each other. While the title device is moved using the EDR up to this time, the reliability of the operation in the second operation parts 4c and 4c', namely, the reliability of the new EDR, can be grasped. When it can be confirmed that the new EDR is sufficiently reliable, a switching part 4e is switched so that the operation result of the second operation parts 4c and 4c' can be outputted, and after that, real reading and image processing are executed according to reading conditions and image processing conditions based on the new EDR. |
