PROBLEM TO BE SOLVED: To provide a structure of key operation part for a composite copier which enables a user to switch, without misreading, the operating keys of the composite copier having a facsimile function and a printer function other than a copy function and has a small number of switches for detecting switching thereby enabling cost reduction. SOLUTION: A plurality of key switching panels 2, 3 and 4 pivotally supported by a single guide shaft 9 (three pieces in Figure) are provided at a position of a case main body 1 having a large number of operating keys 8 where the key switching panels are engaged with the keys 8. The base end sides of the key switching panels abut on and engages with a single second switching mechanism part 19 while turning by 90 degrees, and sends a signal for turning on or off to a control part. A first switching mechanism part 18 turned on or off by 180-degree turning toward one direction engages with each key switching panel 2, 3 and 4. The first switching mechanism part 18 does not operate unless the operation of the second switching mechanism part 19 is turned on. |
