It covers the components such as the window 6 and protects them.

FIGS. 1 and 2 are enlarged views of a main part showing an internal structure of a moving device of the strobe light emitting unit 3, and FIG. 1 shows a case where the strobe light emitting unit is in a storage position (non-irradiation position). FIGS. 2A and 2B are diagrams showing a case where the strobe light emitting unit is at a protruding position (irradiation position).

As described above, the strobe light emitting section 3 is movably supported between the projecting position and the storage position with respect to the camera body. That is, as shown in FIGS. 1 and 2, one end of the strobe light emitting unit 3 is connected by a shaft 8 at one end of a connecting member 7 that supports the strobe light emitting unit 3 movably. Thus, the strobe light emitting section 3 is supported movably.

FIGS. 4 and 5 show the rubber 1 as the thin film member.
FIG. 4 is a perspective view showing the structure of the strobe light emitting unit 3 in a retracted position, and FIG. 5 is a diagram showing a state in which the strobe light emitting unit 3 is in a protruding position. These rubbers 10 (10a, 10b) are provided with folded portions 1 in the middle.
It has a conical shape or a polygonal pyramid shape having 1 a and 11 b, and the opening at the bottom thereof is attached to the fixing portions 12 and 13.

On the other hand, a drive lever 20 which engages with the arm 14 of the strobe light emitting section 3 and moves the strobe light emitting section 3 is rotatable by a shaft 19 to a fixing member (not shown) of the camera body. It is pivoted. The shaft 19 has a cam surface 17a, 17b parallel to the optical axis and a cam surface 17c formed by a slope connecting the cam surfaces 17a, 17b.
Is supported.

On the other hand, a projection 5a is provided on the outer peripheral surface of the lens frame of the photographing optical system 5, and when the lens frame of the photographing optical system 5 is retracted or extended, the photographing is performed. With the straight movement of the lens frame of the optical system 5 in the optical axis direction,
The projection 5a abuts against the cam surface 17c of the cam 17, and the cam 17 rotates by suppressing the cam surface 17c.

The drive lever 20 is biasing means wound around a shaft 19, and is driven in one direction (clockwise in FIG. 1) by the biasing force of an opening spring 18 which constitutes a part of the drive means. The cam 17 is rotated in the direction of rotation of the cam 17 that rotates with the extension operation of the photographing optical system 5, and the biasing force is received by the cam 17 via the drive lever 20. Thus, the drive lever 20
The cam 17 and the cam 17 are integrally rotated in one direction (clockwise in FIG. 1).

Accordingly, the strobe light emitting section 3 is housed in the camera main body 1 in conjunction with the operation of prohibiting photographing of the lens frame of the photographing optical system 5, and the strobe light emitting section 3 is interlocked with the photographing permitting operation. Are projected from the camera body 1 against the urging force of the closing spring 9.

In the arm portion 14 of the strobe light emitting section 3, a pair of lead wires for passing a main current for causing the strobe light emitting section 3 to emit light and a lead wire for sending a trigger signal for starting light emission. A total of 3 leads 1
5 are provided.

When the strobe light emitting section 3 is in the stowed position, the drive lever 20 and the arm section 14 are set so as to be separated from each other so as to form a predetermined gap. The storage position of the strobe light emitting unit 3 is correctly regulated by the position regulating units 1a and 1b provided in the camera body 1.

The relationship between the force of the closing spring 9 and the force of the opening spring 18 is set so that the amount of force of the opening spring 18 is greater than the force of the closing spring 9.

In the camera body 1, there are position regulating portions 1d and 1a for regulating the rotation of the strobe light emitting portion 3 to a position corresponding to the projecting position and the storage position, and a rotating position of the connecting member 7 to the projecting position. And a position restricting portion 1b, 1c for restricting the position to a position corresponding to the storage position.

Next, a description will be given of the operation of moving the strobe light emitting unit 3 in the camera having the above-described configuration. First, as shown in FIG. 1, when the strobe light emitting unit 3 is at the storage position in the camera body 1, for example, the lens barrier 2 is slid in the opening direction or the like, and a power switch (not shown) interlocked therewith. And so on, the strobe light emitting section 3 shifts to the projecting position, that is, the state shown in FIG.

Here, when the strobe light-emitting unit 3 moves from the storage position to the protruding position, first, the strobe light-emitting unit 3 is restricted to a position corresponding to the storage position (position control unit 1a). A first operation in which the strobe light emitting section 3 and the connecting member 7 are integrally moved from the storage position of the position control section 1b to the projecting position of the position restricting section 1c, and then the connecting member 7 is moved by the position restricting section. The second operation is performed in which only the strobe light emitting portion 3 moves from the storage position of the position restricting portion 1a to the projecting position of the position restricting portion 1d while being restricted to the protruding position of 1c.

In the state shown in FIG. 1, the projection 5a on the outer peripheral surface of the lens frame of the photographing optical system 5 is in contact with the cam surface 17a of the cam 17, and the drive lever 20 is It is not rotated.

The stroboscopic light emitting portion 3 is biased in a clockwise direction in FIG. 1 around the shaft 8 by the urging force of the closing spring 9, that is, in a direction in which the stroboscopic light emitting portion 3 is always housed in the main body. I have. At this time, the strobe light emitting unit 3 is in contact with the position control unit 1a, and the position is regulated at the storage position. This restricts the strobe light emitting unit 3 from entering the camera body 1 any more.

On the other hand, the connecting member 7 is connected to the closing spring 9
Is urged through the strobe light emitting portion 3 in the opposite direction, that is, in the counterclockwise direction in FIG. 1 around the shaft 7a. At this time, the connecting member 7 is in contact with the position restricting portion 1b, and its rotation is position-restricted. As a result, the connection member 7 is regulated so as not to rotate any more. Thus, the strobe light emitting unit 3 is accurately positioned at the storage position of the camera body 1.

In this state, the rubber 10 (10a, 10a
As shown in FIG. 1 and FIG. 4, b) is maintained in a state of being bent from the top opening to the bottom opening with the folded portions 11a and 11b as vertices.

On the other hand, when the strobe light emitting unit 3 is in the stowed position and the strobe light emitting unit 3 is forcibly pulled out by hand or the like, the strobe light is pressed against the urging force of the closing spring 9. The light emitting unit 3 projects from the camera body 1, but in this case, no load is applied to components other than the closing spring 9.

When the strobe light emitting unit 3 is in the storage position, the rubber 10 (10a, 10b) is maintained in a bent shape at a position avoiding the connecting member 7. And
When the force for pulling out the strobe light emitting unit 3 is released, the strobe light emitting unit 3 returns to the predetermined storage position by the urging force of the closing spring 9.

Next, the case where the strobe light emitting section 3 is at the projecting position with respect to the camera body 1, that is, the state shown in FIG. 2 will be described. That is, when the lens barrier 2 is slid to the position shown in FIG. 3, the photographing optical system 5 and the like are opened, and the lens frame of the photographing optical system 5 is extended in conjunction with this. Will be

When the lens frame of the photographing optical system 5 is extended, the projection 5a on the outer peripheral surface thereof comes into contact with the cam surface 17c of the cam 17. Then, along with the linear movement of the lens barrel of the photographing optical system 5 in the optical axis direction, the cam 17 rotates around the shaft 19 to the position where it comes into contact with the cam surface 17b in the clockwise direction in FIG. I do.

At this time, the relationship between the force of the closing spring 9 and the force of the opening spring 18 is set so that the force of the opening spring 18 is greater than the maximum force of the closing spring 9 as described above. In conjunction with this, the drive lever 20 rotates clockwise in FIG.

Therefore, the drive lever 20 comes into contact with one end of the arm 14 of the strobe light emitting section 3 and presses it. Then, the strobe light emitting unit 3 rotates counterclockwise about the shaft 8 in FIG. 1 against the urging force of the closing spring 9. Then, the strobe light emitting section 3
Projecting portion 3a comes into contact with the position control portion 1d, and the position is regulated at the projecting position.

On the other hand, the connecting member 7 is rotated clockwise in FIG.
c, and the position is regulated at the projecting position. As a result, the strobe light emitting unit 3 moves in the protruding direction with respect to the camera body 1.

At this time, the rubber 10 (10a, 10b)
When the strobe light emitting unit 3 is sequentially projected, the actual folded portions 11a and 11b are sequentially moved to the top opening side.

When the extension of the lens frame of the photographing optical system 5 is completed, as shown in FIG. 2, the cam 17 and the drive lever 20 are rotated by the projection 5a. At the same time, the opening spring 18 is charged.

In this state, the rubber 10 (10a,
10b), as shown in FIGS. 2 and 5, the vicinity of the top opening is folded back. Then, the folded part 11
As can be seen from FIG. 2, a and 11b are extended in a substantially linear shape. Therefore, the rubber 10 (1
0a, 10b) is maintained in a substantially linear shape from the top opening to the bottom opening.

On the other hand, if the strobe light-emitting unit 3 is forcibly pushed by hand or the like while the strobe light-emitting unit 3 is in the protruding position, the opening spring 18
Is further charged, but in this case, no load is applied to components other than the opening spring 18 and the like.

Therefore, the internal mechanism of the camera and the components of the moving device of the flash light emitting unit 3 are not damaged. Then, when the force for forcibly pushing the strobe light emitting unit 3 is released, the strobe light emitting unit 3 is returned to a predetermined projecting position by the charge of the opening spring 18.

Also, even when the operation of extending the lens frame of the photographing optical system 5 is performed in a state where the strobe light emitting unit 3 is pressed down by hand or the like so as not to protrude, the strobe light emitting unit 3 does not A series of projecting operations as described above, that is, the projection 5a of the lens frame comes into contact with the cam surface 17c of the cam 17 to rotate the cam 17, and the drive lever 10 suppresses the arm 14. Here, since the strobe light emitting unit 3 is pressed so as not to protrude, the opening spring 18
Will be charged.

As a result, no load is applied to components other than the opening spring 18. Also, when the strobe light emitting unit 3 is in the protruding position as described above,
The rubber 10 (10a, 10b) moves to the place where the connecting member 7 was when the strobe light emitting unit 3 was at the storage position. Therefore, it is not necessary to newly secure a space for the rubber 10.

After the completion of the extension operation of the lens frame, if the force by the hand or the like that has held down the strobe light emitting unit 3 so as not to protrude is released, the strobe light emitting unit 3 is opened by the opening spring 18. , It projects to a predetermined projecting position.

In the above-described embodiment, the rubber 10, which is a thin film member, is provided for waterproofing between the strobe light emitting unit 3 and the camera body. It may be provided for the purpose of drip-proof, dust-proof and light-shielding.

Further, in the above-described embodiment, the rubber 10 which is a thin film member is used as the waterproof mechanism of the strobe light emitting section 3, but the present invention is not limited to this.
