A setting of control information changing apparatus having first and second operational components, a setting change device, and a switching device. The setting change device changes the setting of the first control information, for example, in response to the independent operation of the first operational component, and changes the setting of the second control information in response to simultaneous operation of both of the first and the second operational components. The switching device switches the operation of the setting change device between a possible condition in which the setting change of the first control information is possible and an impossible condition in which the setting change of the first control information is not possible. When the setting change device is in the impossible condition, the first control information is not changed if the first operational component is in operation, while the second control information can be changed by the simultaneous operation of the first and the second operational components. Therefore, changing operation of the undesirable control information is certainly prohibited.
