SWITCHING OPERATION DEVICE

PROBLEM TO BE SOLVED: To provide a switching operation device preventing degradation of operability due to adhesion of dust. SOLUTION: The switching operation device for state switching of an apparatus, capable of switching in three states or more by switching two or more components, is provided with operating handles 1, 2 for each component. The operating handles 1, 2 change a component, respectively, by back-and-forth movement between two given positions along a given operating direction, and at the same time, are arrayed in parallel in an opening 3 provided at an outer shell of the apparatus. Furthermore, one end 24 of the operating handle 2 is overlapped with the other operating handle 1, along the operating direction, and at the same time; and a through-hole penetrating through an inside of an end part 14 is provided at an overlapped side, with a channel communicating with the through-hole between the operating handles 1, 2 and the apparatus. As a result of this, operability of the operating handles 1, 2 are improved, and dust adhered to the end part 14 at the overlapped side can be readily removed. COPYRIGHT: (C)2011,JPO&INPIT
