A device comprising:
- a main unit which has an arc-shaped groove and a fixed hook formed on and projecting from the groove;
- and
- a plate-shaped bayonet ring which has, on the back face thereof, an arc-shaped projection to be engaged in the groove and a stop hook to go under the fixed hook and stopped by the fixed hook when the projection is engaged in the groove and rotated,
- wherein the bayonet ring has a mark formed in a predetermined position on the front face thereof and the projection has a notch at least in a backside of a portion including the position where the mark is formed so that the backside is isolated from the bottom of the groove, and wherein a part of the bayonet ring which is furthest away from the mark is lifted by pressing the mark in such a state that the bayonet ring is rotated up to a detachment position.
A camera which includes an image-taking lens as well as an image-pickup device and generates an image signal by capturing a subject light coming through the image-taking lens by using the image-pickup device, comprising:
- a camera body which has an arc-shaped groove formed in such a position as to surround the image-taking lens and a fixed hook formed on and projecting from the groove;
- and
- a plate-shaped bayonet ring which has, on the back face thereof, an arc-shaped projection to be engaged in the groove and a stop hook to go under the fixed hook and stopped by the fixed hook when the projection is engaged in the groove and rotated,
- wherein the bayonet ring has a mark formed in a predetermined position on the front face thereof and the projection has a notch at least in a backside of a portion including the position where the mark is formed so that the backside is isolated from the bottom of the groove, and wherein a part of the bayonet ring which is furthest away from the mark is lifted by pressing the mark in such a state that the bayonet ring is rotated up to a detachment position.
