Abstract:
1. An intermediate adapter, comprising: a first mount unit having a first mount center point, at which a camera body, with twelve body connector terminals disposed near a camera body mount unit at the camera body, is mounted; a body-side connector terminal holding portion where twelve body-side connector terminals, each connected to one of the twelve body connector terminals and each including a contact area to come into contact with one of the body connector terminals, are disposed; a second mount unit having a second mount center point, at which a camera accessory is to be detachably mounted, wherein: the twelve body-side connector terminals are: an interior angle formed by the contact area of the first body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is largest among interior angles, each formed by contact areas of any two body-side connector terminals among the twelve body-side connector terminals at the first mount center point; an interior angle formed by the contact area of the eleventh body-side connector terminal and the contact area of the twelfth body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal through the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the third body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal and the fourth body-side connector terminal through the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the fourth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal and the fifth body-side connector terminal through the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the fifth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal and the sixth body-side connector terminal through the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the eighth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal, the sixth body-side connector terminal, the seventh body-side connector terminal, the ninth body-side connector terminal and the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the ninth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal, the sixth body-side connector terminal, the seventh body-side connector terminal and the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the tenth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal, the sixth body-side connector terminal and the seventh body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the sixth body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of any body-side connector terminal among the first body-side connector terminal, the second body-side connector terminal and the seventh body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; an interior angle formed by the contact area of the seventh body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of either the first body-side connector terminal or the second body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point; and an interior angle formed by the contact area of the second body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point is smaller than an interior angle formed by the contact area of the first body-side connector terminal and the contact area of the eleventh body-side connector terminal at the first mount center point.
