とを企図したものである。[Detailed description of the invention] The present invention is an improvement of the bellows device for close-up photography used in eye reflex cameras, and is designed to be used in close-up photography for various cameras produced by numerous manufacturers. It is intended that the system can be used commonly for different camera mechanisms.
すなわち上記目的を達成するために、蛇腹装置の構造の
一部を各社のカメラに適合するように改良すること、更
に具体的には、蛇腹装置とカメラ本体およびレンズ本体

ブタ取付環２および２′が取付けられる。1. The bellows main body 1 is mounted so that it slides forward and backward by rotating the binion handle 13 on the guide rack 12 to expand and contract the bellows, and faces a camera body and a lens body (not shown), respectively. Swallowtail attachment rings 2 and 2' are attached to the bellows openings, respectively.
従来の接写撮影においては、カメラ本体とレンズ本体と

A concave shape cut into the upper end of the rectangular thin plate-shaped interlocking levers 4, 4/ which stand integrally and parallel to each other from the rectangular fitting frame 6 fitted so as to non-rotately slide against the rectangular fitting frame 6. Depth of cut 5,5'
Since it is inserted into the inside of both adapters i10,10'
It will be appreciated that the rotational movements of can be performed in a one-to-one interlocking relationship.

The aperture operating lever (not shown) and the aperture lever (not shown) of the lens body are in a relationship that engages with and interlocks with the aperture operating lever (not shown).
各アダプタ外側環９．９’の外端面は、各連中カメラに

．． The mounting mechanism with 2' should be marked with an appropriate fitting indicator (for example, a red dot).
They are fitted by aligning them and rotating by a small angle (for example, 60 degrees) in a predetermined direction (for example, as indicated by the red arrow), and when detaching, the operation can be performed in the reverse order.

Having a one-to-one interlocking mechanism between 7' and the adapter 7
．． It can be seen that since the camera body 3 and the lens body are coupled to the outside of the lens body 7', when the shutter of the camera is pressed, the operation of the aperture lever of the camera body, which is linked to this, is linked to the aperture operation of the lens body.

を有するものである。As described above, when taking close-up shots with various different models of single-lens reflex cameras, the present invention enables the bellows to be adjusted simply by replacing the adapter of the present invention, without having to replace the entire bellows device dedicated to that camera each time. The part and its telescopic guide rack stand have the convenience of being commonly used and the practical advantage of saving parts.
