いる。Conventionally, this type of lens mount mechanism was developed using the
The one disclosed in Japanese Patent No. 9-5519 is known and has a structure as shown in FIG. In Fig. 7, the main body mechanism section (71)
is housed and supported in the outer box (72) so that even if the outer box (72) deforms due to pressure, the deformation does not affect the outer box (72).
72) and the back cover (73), which is pivotally supported, are sealed waterproof by an 0 ring (74).
1) has a mount portion (75) fixed to it. Further, an opening (72a) is provided on the front surface of the outer box (72).

きをする。On the other hand, the lens mechanism section is composed of an outer cylinder part (76) and an inner cylinder part (77), and the inner cylinder part (77) is connected to a photographic lens (78).
It also includes a distance adjustment mechanism, an aperture adjustment mechanism, etc. (not shown). The outer cylinder part (76) consists of a pressure-resistant and waterproof mechanism,
The front opening has a waterproof glass (79) with an O ring (710).
) and sealed waterproof. Furthermore, in the circumferential groove (76a) provided around the rear opening, an O ring (
711) is fitted. As a result, when the lens is attached to the camera, a waterproof seal is created between the lens outer cylinder part (76) and the outer case (72). A lens mount portion (712) is fixed to the inner cylinder portion (77). The lens mount part (712) connects the outer cylinder part (76) to a plurality of axes (713).
It is pivotally supported so that it can move in the optical axis direction. Each axis (71
The spring (71-1 unit) fitted around 3) serves to pull the outer cylinder part (76) toward the mount part (7) 2).

ず、機能を維持することが出来る。When the lens is attached, the lens mount part (712) is attached to the plurality of bayonet claws (75a) of the main body mount part (75).
The bayonet part (712a) of the two meshes with each other, and the lens inner cylinder part (77) is fastened to the main body mechanism part by the biasing force of the spring (71 joint). (77) is not affected by deformation of the outer box part (72) and the lens outer cylinder part (76) by water pressure, and can maintain its function.
しかしながら、上記構成では下記のような問題点が生ず
る。However, the above configuration causes the following problems.

以上だとすると、外筒部(76)は外箱(72)に対し
て傾いてしまう。(11 The fitting part between the lens outer cylinder part (76) and the outer case opening (72a) is simply a waterproof seal structure with an O ring (711), so the optical axis If a force in a right angle direction is applied to the spring (714) and the force is greater than the force of the spring (714), the outer cylinder part (76) will tilt with respect to the outer box (72).

(76)が外箱部(72)から浮上ってしまう、いずれ

完全となり、漏水する虞が生ずる。Furthermore, when the pressure inside the camera is higher than the external pressure and its magnitude exceeds the force of the spring (714), the lens outer cylinder section (76) floats up from the outer box section (72). The waterproof sealing effect of the ring (711) will be incomplete, and there is a risk of water leakage.

形が生じ、ピント精度を悪(しかねない。(2) The attachment of the lens mount part (712,) to the main body mount part (75) is maintained by the urging force of a plurality of springs (714), and if the outer cylinder part (76) is tilted, the springs (714, ) may become uneven depending on the location, and the lens mount portion (712) may become unstable. To achieve this, it is best to increase the force of the spring (714) so that the outer cylinder part (76) is less likely to tilt. However, if the spring force is increased unnecessarily, the main body mount (75) will deform and the focusing accuracy will be adversely affected. There is no other way.

11), the lens mount part (712
) is attached correctly to the main body mount (75) at the specified position.Also, as cameras become increasingly electronic, it is difficult to know whether the lens is properly attached to the main body mount (75). Therefore, if the lens is not properly attached to the camera in a predetermined position, there is a risk of malfunction. Furthermore, if the camera is used with the lens attached incompletely, there is a risk that the lens may fall off from the camera, resulting in a flood accident.

両者の間で弾性変形する。Figure 5 shows the state immediately after the waterproof lens mount part is inserted into the waterproof camera mount part. At this time, the relative relationship of each bayonet claw part is in the position as shown in Figure 3, and the lock pin (15) and the recess ( 13f) is in the disengaged position. In this state, as shown in FIG.
), the outer cylinder mount part (70) of the outer cylinder part (7) is inserted into the outer mount part (2a) of the outer box (2), and the 0 The ring (10) deforms elastically between the two.

全に解消され、防水レンズは回動可能となる。The end surface (13e) of the inner cylinder mount is pressed against the main body mount surface (5C) by the biasing force of the spring (14) and pushes the lock pin (15) to the right in the figure, so the switch (19)
becomes ON. In the state shown in Fig. 5, the outer bayonet claws (2C), (2d) and the outer bayonet claw (7b
) and (7C) interfere with each other in the rotational direction, so it is not possible to turn the waterproof lens to the position shown in Figure 4, but the outer cylinder part (7C)
) is further pushed toward the right in the figure against the spring (14), the interference is completely eliminated at the position where the end surfaces (7e) and (2e) abut, and the waterproof lens becomes rotatable.

保持される。In this example, the rotation angle required to attach the waterproof lens is 9.
0°, and when the waterproof lens is rotated 90° from the state shown in FIG. 3, it becomes the fully installed state shown in FIG. 4. Each bayonet claw part is (13a), (5a), (13b) and (5
b), (7b) and (2C), (7G) and (2d) are engaged with each other, and as shown in FIG.
One end (15a) of the lock pin (15) provided on the inner mount (5) is located in the recess (13f) of the end surface (13e) of 3).
) is depressed by the biasing force of the spring (16) and locks the rotation of the lens. At the same time, the bayonet spring (-6)
As shown in the figure, press the inner bayonet claws (13a) and (13b) to the right in the figure, and
Since the end face (13e) of the inner cylinder mount part (13) is brought into close contact with c), the inner cylinder part (11) and the main body mechanism part (1) are integrated in both the rotational and optical axis directions. Also, the outer cylindrical bayonet (7b), (7C) and the outer bayonet (2c), (2d)
are engaged with each other, and the outer cylindrical portion (7) is engaged and held with the outer case (2).

の信号を本体カメラ機構部(1)に伝達する。Note that when the lens is not attached to the camera, the lock pin (15) protrudes to the position indicated by the broken line in Fig. 6 due to the biasing force of the spring (16), so the switch member (19) is turned OFF.
However, when the lens is inserted into the outer mount part (2a) as shown in Figure 5, the switch member (19)
is in the first ON state, and when it is completely attached as shown in FIG. 6, it is in the second ON state, and each transmits separate signals to the main body camera mechanism section (1).

える。(2) An outer cylinder mount (70) is provided on the outer cylinder part (7), and when the lens is attached, the outer cylinder mount (70)
By engaging with the outer mounting part (2a) of the outer case (2), the outer cylinder part (7) and the outer case (2) are integrated, so that the external force is applied to the outer cylinder part (7). Even if the external cylinder part (7) is exposed to water or the internal pressure increases, the outer cylinder part (7) will not tilt or float, and a waterproof seal can be ensured.
