りするという操作は非常に面倒であった。Conventionally, the so-called T-mount is a system in which a female mount for attaching an interchangeable lens is attached to a main body having a male mount. The positional relationship of the external threads of the lens may vary depending on the state of the threading, so when it is attached to the camera, the indicator mark may not be located on the front of the camera. Therefore, in the past, the female mount was fixed with several setscrews around the periphery, and each of the setscrews was loosened while the female mount was attached to the camera, and after rotating the female mount and aligning the indicator mark to the correct position, The set screws are then individually tightened to fix the device, but the operation of loosening and tightening several set screws is extremely troublesome.

に係合するよう係止片（１３）を設けである。A mounting screw (5) is formed on the inner periphery of the receiving hole (the female mount l□ (61 is rotatably fitted into the female mount θ), and a locking portion (7) of an appropriate shape is formed around the female mount θ. ) (dry, the one shown in the figure is approximately square θ) with a protrusion of approximately 70D.
; The protrusions are provided at intervals of f, and preferably the width run 1 is slightly wider at the distal end than the proximal end of the protrusion; It can also be formed into The female mount is held by a holding plate (9) fixed to the main body from the side with screws (8),
A small gap is provided between the holding plate and the female mount so that the female mount can rotate easily.
0) is provided with a protruding presser spring (see Figure G), and the support portion of the presser spring is provided with a groove t provided with a female mount L-K.
+2) K Insert and urge the female mount toward the male mount. A locking piece (13) is provided on the inner surface of the receiving hole so as to engage with the upper iF locking part.

がある。The one shown in the figure has a substantially rectangular protrusion (141) that engages with the above-mentioned locking portion, but the shape of the locking piece may vary depending on the structure of the locking portion. The first stop piece is pivotally attached to the main body (15), and is preferably biased by a spring (16) so as to always engage with the locking part.One end of the spring is The stop bar (17) ff is formed by raising the tip of the stop piece, and the other end is in contact with the inner wall of the main body (181, shown in the figure f), as well as various biasing forces. In the case shown in the figure, the above-mentioned locking piece 0) and the operation end (19) are almost overlapped, and the two locking pieces are provided facing each other and are almost symmetrical to this. The position y is provided with a connecting piece 11 having almost the same configuration. A push button (2 (++

く形成することもで゛きろ。After screwing the male mount (not shown) of the interchangeable lens into the female mount and attaching the female mount (not shown) of the above-mentioned male mount camera, press the above push button to release the locking piece and the above female mount. When the locking part is disengaged, the female mount 1 becomes rotatable.
The interchangeable lens can be rotated so that the instruction mark (not shown) on the interchangeable lens is in the correct position, and in that state, the above-mentioned locking piece can be engaged with the locking part of the female mount. ,
This can be done by setting the interchangeable lens in the camera in the correct condition. In addition, although the locking piece shown in the figure is operated by a push button, it is possible to simply provide a hole in the main body and use an operating piece with an appropriate pin to operate the operating end of the locking piece. Alternatively, the operating end may be exposed on the outer periphery of the main body and the operating end may be pressed directly with a fingertip. In addition, in the case shown in the figure, the protrusions of the locking piece engage with the locking portion of the female mount at the total position. However, the number of engaging portions may be larger or smaller than that.
