Therefore, according to the above configuration, by connecting the ST unit 13 to the camera body 3, connection for supplying power from the camera body 3 for light emission to the ST unit 13 can be easily performed. By arranging the ST unit 13 near the driving unit in the camera body 3, the drive transmission mechanism for pop-up driving the ST case 13A can be simplified.

By the way, in the camera 1 according to the present invention, even when the ST unit 13 is attached to the camera body 3 as described above, the front cover 4 and the rear cover 5 as the camera exterior members that sandwich the camera body 3 are provided. And the projection position and the storage position during the pop-up operation of the ST case 13A are securely positioned using the camera exterior member (the front cover 4 or the rear cover 5), and the pop-up is performed safely and smoothly. Improvements have been made to perform the operation. Such a configuration example will be described with reference to FIGS.

FIGS. 4 and 5 are enlarged views showing the structure of the drive transmission link mechanism of the ST unit including the above-described pop-up positioning restricting means. FIG. 4 shows the ST case in the storage position (non-photographing position). FIG. 5 shows a case where the ST case is at the protruding position (photographing position).

In this embodiment, in order to securely and smoothly perform the pop-up operation, the projecting position and the storage position during the pop-up operation of the ST case 13A are securely and smoothly performed at a low cost. It is characterized in that positioning restricting means for positioning the protruding position and the storage position are provided at corresponding portions of the front cover 4.

More specifically, as shown in FIG. 4, the storage positioning section 4 for positioning the storage position of the ST case 13A.
a is provided at a predetermined position on the inner portion of the front cover 4 to engage with the ST case 13A. On the other hand, two protruding engagement portions 13g are formed on the bottom surface of the ST case 13A at positions corresponding to the storage positioning portions 4a.
When the ST case 13A is in the storage position, the engagement portion 13g on the bottom surface of the ST case 13A engages with the storage positioning portion 4a of the front cover 4, so that the storage position of the ST case 13A is regulated and positioned. .

Further, as shown in FIG.
A photographing positioning unit 4 that performs positioning at the projecting position of A
b is provided at a predetermined position inside the front cover 4. When the ST case 13A is at the projecting position, the photographing positioning projection 1 provided at the lower portion of the ST case 13A is provided.
3b and the photographing positioning unit 4b come into contact with each other. When the ST case 13A is in the protruding position, the photographing positioning projection 13b provided at the lower part of the ST case 13A is locked by the photographing storage positioning part 4b provided on the front cover 4, so that the ST case 13A The protruding position (imaging position) is regulated and positioned.

Next, the pop-up drive transmission operation of the ST unit utilizing such positioning means will be described.

Now, ST case 13 of ST unit 13
It is assumed that A is in the storage position (non-photographing position).

In this case, the ST case 13A is rotatably attached to one end of the ST link 14 via the ST case shaft 15 and the ST bar spring 17a. Since the case 13A is urged in the direction of the ST link 14 (closing direction) with the ST case shaft 15 as a rotation axis, FIG.
As shown in (1), the engaging portion 13g comes into contact with the storage positioning portion 4a of the front cover 4. Thereby, the position of ST case 13A with respect to front cover 4 at the storage position (non-photographing position) can be regulated.

The other end of the ST link 14 is
ST via T-link jig 13C, ST spring 17b
Since the ST link 14 is constantly urged toward the bottom surface of the ST body 13B by the ST torsion spring 17b, the ST link 14 is rotatably attached to the bearing portion of the main body 13B, as shown in FIG. Reference numeral 14 rotates around the ST link shaft 13C as a rotation axis and is accommodated in the ST main body 13B.

At this time, the storage position of the ST case 13A is regulated and positioned by the engagement of the engagement portion 13g on the bottom surface of the ST case 13A with the storage positioning portion 4a of the front cover 4.

Further, the first S of the pop-up drive transmission mechanism
The T cam lever 25 is urged counterclockwise around the mounting shaft 3c in FIG. 4 by the spring force of the ST springs 17a and 17b. At this time, the ST drive cam portion 24a provided on the outer surface of the ST cam gear 24 interlocked with the drive portion in the camera body 3 has the initial position (the most proximal end side of the cam) of the strobe drive region set to the first ST position. Since the rotational position is such that the contact portion 25b of the cam lever 25 can contact the contact portion 25b, the contact portion 25b of the first ST cam lever 25 contacts the ST drive cam portion 24a at the initial position.

The ST case 13A includes an ST spring 17a,
Since the ST lever 18 and the second ST cam lever 25 are constantly urged to the storage position by the spring force of 17b, the ST lever 18 and the second ST cam lever 25 receive the clockwise rotation force in FIG. . The rotational force is applied to the arm portion 20b of the second ST cam lever 25 and the sliding pin 25a of the first ST cam lever 25.
It is transmitted to the cam lever 25. Therefore, the first ST cam lever 25 is provided with a counterclockwise rotational force in the figure around the mounting shaft 3c.

With this configuration, the ST cam gear 24
5 rotates from the pop-up position shown in FIG. 5 to the pop-down position shown in FIG. 4 in a counterclockwise direction around the mounting shaft 3c, and accordingly, the second ST cam lever. 20 rotates clockwise in the figure around the ST leverage 19.

As the second ST cam lever 20 rotates,
The ST lever 18 pivotally supported via the second ST cam lever 20 and the ST lever 19 also rotates clockwise in the figure around the ST cam lever shaft 19, that is, the drive unit 18a of the ST lever 18 (see FIG. 5). Is rotated toward the bottom surface of the ST main body 13B, so that the ST lift 16 engaged with the ST main body 13B also rotates counterclockwise in the drawing with the ST link jig 13C as a rotation axis.

In this way, the driving portion 16a formed at the tip of the ST lift 16 slides on the bottom surface of the engaged ST case 13A, thereby moving the ST case 13A.
The engagement of the drive unit 16a with A is released, and at the same time, the ST case 13A is housed in the ST body 13B by the urging force of the springs of the ST springs 17a and 17b. In this case, as described above, the storage position of ST case 13A is regulated and positioned by engaging engagement portion 13g on the bottom surface of ST case 13A with storage positioning portion 4a of front cover 4 as described above. By doing
The storage position state is as shown in FIG.

Next, a pop-up operation for moving the ST case 13A of the ST unit 13 to the projecting position (photographing position) from the state of FIG. 4 is performed.

When the main switch (not shown) of the camera 1 is turned on with the movement of the barrier 4A from the closed position to the open position, the lens barrel 11 is moved from the retracted position stored in the camera 1 to the shortest focus position. A motor, which is a drive source (not shown), is driven and controlled to extend to a wide position which is a distance. Then, the ST cam gear 24 connected to the reduction mechanism for transmitting the driving force of the motor to the lens barrel 11 rotates counterclockwise (UP direction) in the figure around the gear shaft 3b.

For this reason, the first ST cam lever 25 engaged with the cam of the ST drive cam 24a is
The mounting shaft 3c is pushed up by the cam shape of a.
Will be rotated by a predetermined amount in the UP direction about
Pop-up position. Along with this, the drive pin 25a arranged at the other base end also rotates in the UP direction, so that the engagement portion of the second ST cam lever 20 attached to the lower part of the ST main body 13B is pushed up by the drive pin 25a, thereby increasing the UP. In this direction. In this case, the drive pins 25a are connected to the ST springs 17a, 17a.
It turns while resisting the urging force of b.

Then, the ST lever 18 pivotally supported via the second ST cam lever 20 and the ST leverage 19 also rotates in the UP direction, that is, the drive unit 18 of the ST lever 18.
A (see FIG. 5) rotates the ST link jig 13C as a rotation axis in the UP direction while pushing up the ST lift 16 that engages with it.

Thus, with the rotation of the ST lift 16 in the UP direction, the driving unit 16a formed at the tip moves rightward in the figure while sliding on the bottom surface of the ST case 13A in contact with the driving unit 16a. By pushing up the ST case 13A, the ST link 14
The ST case 13A rotates clockwise about the ST case jig 15 as a rotation axis. That is, the ST case 13A is rotated by the ST link 14 so that the ST case 13A is rotated about S.
It is projected together with the T case jig 15, and is displaced to the protruding position by the rotation about the ST case jig 15 as a rotation axis.

The ST case 13A projects from the ST case 13A by locking the photographing positioning projection 13b provided at the lower part of the ST case 13A with the photographing storage positioning portion 4b of the front cover 4 as described above. When the position (imaging position) is regulated and positioned, a pop-up state as shown in FIG. 5 results.

Further, with the rotation of the second ST cam lever 20, the ST switch lever 21 provided on the back side of the ST main body 13B rotates to determine whether the ST case 13A is in the protruding position or the storage position. An ST switch 29 (see FIG. 9A), which is a switch for detection, is operated. This makes it possible to detect whether the ST case 13A is at the projecting position or the storage position, and the ST case 1
It is possible to prevent erroneous shooting when 3A is in the storage position.

The displacement of the ST case 13A from the storage position to the protruding position is performed during the operation of extending the lens barrel 11 from the retracted position to the wide position. Therefore, with the operation of opening the barrier 4A by the photographer, the lens barrel 11 is extended to the wide position and the ST case 13
A is also displaced to the protruding position, and the photographing preparation is completed. Further, when the photographer operates the zoom operation button 7 to perform a zoom operation, the ST cam gear 24 rotates during the zoom operation because the ST cam gear 24 is connected to the speed reduction mechanism for driving the lens barrel. In this case, the idle running area (zoom area) that is continuous with the strobe drive area (setup area) of the ST drive cam section 24a is such that the first ST cam lever 25 continues to maintain the position shown in FIG. It is formed so that it may become an arc centering on 3b. Therefore, even during zooming, ST case 13A keeps taking the protruding position.

On the other hand, when the ST case 13A is displaced from the protruding position to the retracted position, the photographer closes the barrier 4A, and the main switch of the camera 1 is turned off. Is carried out to the retracted position. At this time, the ST cam gear 24 is do
wn direction, and as described above, the ST
The ST case 13A is stored in the storage position by the spring forces of a and 17b.

By the way, between the second ST cam lever 20 and the ST cam lever 18, as described above, the ST flat spring 1 is provided.
9a is applied, and an urging force is acting in a direction to open each other. As a result, the second ST cam lever 20 and the ST lever 18 rotate integrally within a predetermined load, but when a further load is applied, the ST flat spring 19a
Oppose to each other, they operate independently of each other. Therefore, when driving the ST case 13A from the storage position to the projecting position, the ST case 13A is driven by the two rotating together. On the other hand, S
When the T case 13A is in the protruding position, the ST case 13A
When the second ST cam lever 20 is engaged with the first ST cam lever 25 and cannot rotate, for example, when a force is applied to push the ST cam lever from the storage position to the protruding position, the ST cam lever 18 cannot rotate due to the ST flickering spring 19a. It is rotatable against the urging force. Thereby, ST case 13A
