PROBLEM TO BE SOLVED: To simply correct a program for updating OS in the case a problem occurs in the program for updating OS. SOLUTION: A scanner 1 obtains data for updating OS to be replaced with a part or all of OS and the appropriate program for updating OS for rewriting OS by using the data for updating OS from a host device to be connected with outside via a communication I/F to store in a RAM 35. Namely, the program for updating OS is stored in a semiconductor memory device capable of rewriting by only electrical operation. Consequently, Even if a problem occurs in this program for updating OS, the program is simply corrected. |
