CAMERA BODY, LENS TUBE, AND EXCHANGEABLE-LENS CAMERA |
摘要 |
<p>A camera body, a lens barrel and a lens-interchangeable camera are provided, wherein the lens barrel and the camera body can be reliably prevented from being improperly mounted to each other by a simple structure without incurring a significant increase in cost even in the case where the camera body is miniaturized. A camera body 20 includes a plurality of body-side bayonet lugs 25, 26 and 27 which are provided on the peripheral edge of an opening; and a protrusion 32 which is positioned in a circular-arc opening 28, 29 or 30 formed between adjacent body-side bayonet lugs of the body-side bayonet lugs, the distance between the protrusion and either of adjacent two body-side bayonet lugs of the body-side bayonet lugs being shorter than each of the lens-side bayonet lugs 55, 56 and 57; and a body-side mount surface 24 with which the lens-side bayonet surface comes into contact from the front side when the lens-side bayonet lugs are positioned immediately behind the body-side bayonet lugs.</p> |
