BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a macro strobe photographing apparatus according to the present invention. In FIG. 1, a strobe light emitting means 1 includes a strobe light emitting tube 2 composed of a xenon discharge tube or the like, and a reflector 3 disposed around the tube. The reflective umbrella 3 has a parabolic cross section, and the strobe light-emitting tube 2 is arranged near the bottom of the parabola. The principle of light emission of the strobe light emitting means 1 is well known. A high-voltage DC charge is accumulated in a main capacitor (not shown), and a trigger circuit 4 is operated by a trigger electrode of a strobe light emitting tube 2 in synchronization with an operation of opening a shutter of a camera. A voltage is applied to the strobe light, which triggers the electric charge stored in the main capacitor to be supplied to the strobe light emitting tube 2 to instantaneously discharge and emit light. The trigger circuit 4 is controlled by the control means 5.

FIG. 1 shows a control system built in the camera. In addition to the trigger circuit 4, the control means 5 includes a distance measuring means 6, a power switch 7, a macro mode switch 8, and a diffusion condition. The changing means 12 is connected. The distance measuring means 6 measures the distance to the subject, and the control means 5 performs flashmatic light emission control based on distance information from the distance measuring means 6. That is, the strobe light emitting means 1
The light emission time is calculated from the guide number determined by the light emission amount and the distance measurement information, and the light emission is stopped for the calculated light emission time.

The strobe light emitting means 1 has a liquid crystal diffusing plate 11 arranged in front of the reflector 3. Liquid crystal diffuser 1
Numeral 1 indicates that the diffusion condition of the light can be changed by the diffusion condition changing means 12. In this example, the diffusion rate of the light emitted from the strobe light emitting tube 2 can be changed in two ways, large and small. . The diffusion condition changing means 12 is controlled by the control means 5. When the power switch of the photographing device (camera) is turned on, the control means 5 controls the diffusion condition changing means 12 so that the liquid crystal diffusion plate 11 is set in advance so that the diffusion rate becomes small. By doing so, the diffusion rate is set to be small immediately after the power switch 7 is turned on, regardless of whether the diffusion condition of the liquid crystal diffusion plate 11 is large or small when the power switch 7 is turned off. It is possible to perform normal photographing by intensively irradiating light emitted from the strobe light tube 2 to a subject at a normal photographing distance. In the control means 5 or outside thereof, there is provided a normal shooting guide number table indicating the relationship between the guide number and the light emission time when the diffusion rate of the liquid crystal diffusion plate 11 is small, and based on this normal shooting guide number table. The strobe light emission tube 2 is controlled to emit light only for the light emission time corresponding to the subject distance at that time.

The macro mode switch 8 is a switch for switching the photographing mode of the camera between a normal subject distance photographing mode and a close-up photographing mode. When the macro mode switch 8 is pressed, the mode is changed to the macro mode. It has become so. When the mode is changed to the macro mode, the information is input to the control circuit 5, and the control circuit 5 changes the diffusion rate of the liquid crystal diffusion plate 11 from small to large via the diffusion condition changing means 12. When the flash photography operation starts, the control means 5 calculates an appropriate flash guide number from the distance to the subject measured by the distance measurement means 6 and the F-number (aperture value) of the lens, and calculates the liquid crystal diffusion. The light emission time is determined from the macro shooting guide number table indicating the relationship between the guide number and the light emission time when the diffusion condition of the plate 11 is high, and the strobe light emitting means 1 emits light for the determined time.

When the diffusion condition of the liquid crystal diffusing plate 11 is high, the illumination light emitted from the strobe light emitting tube 2 is diffused over a wide range. Can be avoided, so that flash photography with proper exposure can be performed even in a macro mode short-distance region. In addition, there is an advantage that the illumination light can be uniformly applied to the entire close subject. The macro photography guide number table is also provided inside or outside the control means 5.

Next, another embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. The embodiment shown in FIG. 2 also has a strobe light emitting means 1, a strobe light emitting tube 2, a trigger circuit 4, a control means 5, a distance measuring means 6, a power switch 7, and a macro mode switch 8. The reflector provided around the strobe light emitting tube 2 is a movable reflector 21. As shown in FIG. 4, the movable reflector 21 has auxiliary reflectors 23 and 24 that move relative to the main body of the reflector 21 to change the size of the reflection surface. The auxiliary reflectors 23, 24
As shown in FIG. 4A, from the position where the reflection surface is enlarged by advancing forward from the upper and lower edges of the main body of the reflector 21 as shown in FIG. It is possible to move within the range from the upper and lower edges to the position where the reflection surface is reduced by retreating. In the position where the reflection surface is enlarged as shown in FIG. 4A, the convergence rate of the light emitted from the strobe light emitting tube 2 is increased, and the illumination light can be intensively applied to the subject. In a position where the reflection surface is reduced as shown in FIG. 4B, the light condensing rate of the light emitted from the strobe light emitting tube 2 can be reduced to diffuse the illumination light over a wide range.

As described above, the movable reflector 21 can change the condensing rate of the light emitted from the strobe light emitting tube 2 into two types, large and small, by changing its shape. This change of the light collection rate is performed by the reflector shape changing means 22.
The shape of the movable reflector 21 by the reflector shape changing means 22 is controlled by the control circuit 5 in accordance with the operation states of the power switch 7 and the macro mode switch 8.

Also in this embodiment, a normal photographing guide number table indicating the relationship between the guide number when the light collection rate is high and the light emission time is provided inside or outside the control means 5, and when the light collection rate is small. A macro shooting guide number table indicating the relationship between the guide number and the light emission time is provided.

Now, when the power switch 7 of the photographing device (camera) is turned on, the shape of the movable reflector 21 is set in advance to the large light collection rate by the reflector shape changing means 22 controlled by the control means 5. Is done. by this,
Irrespective of whether the shape of the movable reflector 21 is large or small when the power is turned off, normal imaging can be performed immediately after the power switch 7 is turned on. In normal flash photography, flashmatic control is performed using a normal photography guide number table.

When the macro mode switch 8 is pressed to change the mode to the macro mode, the control means 5 changes the shape of the movable reflector 21 from the large light-collecting rate side to the small side via the reflector shape changing means 22. change. And when you start flash photography,
An appropriate strobe guide number is determined from the distance to the subject measured by the distance measuring means 6 and the lens F value, and the relationship between the guide number and the light emission time when the shape of the movable reflector 21 is on the small light collection rate side. Is determined from the macro photographing guide number table indicating, and light is emitted for the determined time. In a state where the light collection rate is small, the light from the strobe light emitting tube 2 diffuses into a wide range, so that the amount of illumination applied to a subject in a short distance area is suppressed, and thus, a proper exposure is performed even in a macro mode short distance area. Flash photography can be performed. There is also an advantage that illumination light is uniformly applied to a subject in a short distance area.

Next, a third embodiment will be described with reference to FIG. The embodiment shown in FIG. 3 also has a strobe light emitting means 1, a strobe light emitting tube 2, a trigger circuit 4, a control means 5, a distance measuring means 6, a power switch 7, and a macro mode switch 8. The strobe light emitting tube 2 can be moved inside the reflector so that the light collection rate of the strobe light can be changed.

FIG. 5 shows an example of a structure in which the flash tube 2 can be moved inside the reflector. In FIG. 5, the end plate of the reflector 31 disposed around the strobe light emitting tube 2 has a long hole 33 formed in the front-back direction (left-right direction in FIG. 5). The arc tube 2 can move back and forth. As shown in FIG. 5A, when the strobe light emitting tube 2 is retracted to the rear of the reflector 31, most of the illumination light emitted from the strobe light emitting tube 2 is reflected by the reflecting surface of the reflector 31 and condensed. The rate increases. As shown in FIG. 5B, in a state where the strobe light emitting tube 2 has advanced to the front of the reflector 31, the illumination light from the strobe light emitting tube 2 that travels without being reflected by the reflecting surface of the reflector 31 is exposed to light. And the light collection rate decreases.

As described above, the arc tube moving means 32
As shown in FIG. 5, the strobe light emitting tube 2 can be moved within the reflector 31 to change the light collection rate of light emitted from the strobe light emitting tube 2 into two types, large and small. Such movement of the strobe light emitting tube 2 is performed by driving the strobe light emitting tube 2 by the light emitting tube moving means 32. The arc tube moving means 32 can be composed of a motor, a solenoid, and other appropriate actuators. The operation of the arc tube moving means 32 is controlled by the control means 5.

Also in this embodiment, the normal photographing guide number table indicating the relationship between the guide number and the light emission time when the light condensing rate is high, and the control when the light condensing rate is small are provided inside or outside the control means 5. A macro shooting guide number table indicating the relationship between the guide number and the light emission time is provided.

Now, when the power switch 7 of the photographing device (camera) is turned on, the position of the strobe light emitting tube 2 is previously moved by the light emitting tube moving means 32 to the light collection rate large side as shown in FIG. Set. Thus, even if the position of the strobe light emitting tube 2 is high or low when the power switch 7 is turned off, normal shooting can be performed immediately after the power switch 7 is turned on.
In normal flash photography, flashmatic control is performed using a normal photography guide number table.

When the macro mode switch 8 is depressed to change the mode to the macro mode, the control means 5 controls the arc tube moving means 3
The position of the strobe light-emitting tube 2 is changed from the state of high light-collection rate shown in FIG. 5A to the state of low light-collection rate shown in FIG. Then, when the flash photography is started, an appropriate flash guide number is obtained from the distance to the subject measured by the distance measuring means 6 and the lens F value, and when the position of the flash arc tube 2 is on the small light collection rate side. The light emission time is determined from the macro shooting guide number table indicating the relationship between the guide number and the light emission time, and light is emitted for the determined time. In a state where the light collection rate is small, the light from the strobe light emitting tube 2 diffuses into a wide range, so that the amount of illumination applied to a subject in a short distance area is suppressed, and thus, a proper exposure is performed even in a macro mode short distance area. Flash photography can be performed. There is also an advantage that illumination light is uniformly applied to a subject in a short distance area.
