PURPOSE:To prevent generation of unexpected accidents by judging whether or not an abnormality mode should be reset or not according to content or state of the abnormality. CONSTITUTION:When abnormality is detected, a code for the abnormality is stored in RAM111 and the mode is transferred to the state where no operation is possible by displaying abnormality on a display panel 49. When a trigger at the time of power ON is detected and if the abnormality code stored in the RAM111 is a code where the abnormality is not reset, abnormality display is carried out and the mode is transferred to the operation unable state. When it is a code other than the resettable code, the abnormality display is reset and the operation enable state is made. Thus, unexpected accidents can be prevented. |
