PROBLEM TO BE SOLVED: To make intuitively recognizable the turning position of a mount ring and to make rapidly changeable a lens by providing a bayonet mount and the mount ring and giving a click feeling in the case of turning the mount ring to a changeable lens attaching/detaching position. SOLUTION: This device is equipped with the mount ring 4 capable of turning to a 1st position where the changeable lens can be attached to/detached from the bayonet mount 3 and a 2nd position where the changeable lens can be locked. The ring 4 is provided with a circular-arc shaped slot 7 corresponding to its turning range. The mount 3 is provided with a turning position regulating pin 8 which moves in the slot 7 to regulate the turning position of the ring 4 and whose tip part is energized in a projecting direction. The slot 7 is provided with a recessed part 12 in which the tip part of the pin 8 is fit when the ring 4 is turned to the 1st position.
