PROBLEM TO BE SOLVED: To provide a composite copying machine capable of suppressing the increase of the scale of the whole device by making an operation surface laminated being free to select in accordance with the functions of the device, reducing the number of arrays of arrayed keys on the operation surface, and executing the operation of coping with multiple functions without misoperation. SOLUTION: A key unit 20 provided with key tops 20a of the first functions of the device on the surface is attached freely openably/closably to the operation surface provided with key tops 21a of the second functions of the function part main body case 1 of the device. The opening/closing of the key unit 20 are detected by a changeover switch 51 to switch the setting of the first and second functions. Thus, the multiple functions are fulfilled with excellent operability, without expanding a key array surface at the time in use, a function part is miniaturized and the number of components are reduced. Further, the manufacturing costs can be reduced. |
