PURPOSE:To secure the easy program loading with various types of recording styles by using a readable/writable nonvolatile memory and adding a loader to this nonvolatile memory. CONSTITUTION:An initialized program to be loaded is stored to a readable/ writable nonvolatile memory 3. A style identifier is first written to the memory 3 via a style control part 5, etc. by an initial loading command given when a electric power supply is applied. When a style identifier of A is stored in the memory 3, the identifier A read out via a memory reading part 8, etc. is loaded by a basic program loader 10 stored in an ROM1. In case of a style indentifier B is set, this identifier B is read via a loader reading part 9 and can be loaded by an extended program loader 11. Thus the automatic initial loading is possible by a prescribed loader after the style is once set. This ensures loading of various types of programs. |
