Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-integrated camera in which a film cartridge is loaded in advance at the time of assembling, the photographic film is wound up for each photographing, and the photographed photographic film is taken out.

[0002]

2. Description of the Related Art A film-integrated camera is a simple camera in which a film cartridge is loaded in advance at the time of assembling, the photographic film is wound up each time a picture is taken, and the taken photographic film is taken out. Some film-integrated cameras also include a strobe device that causes a discharge tube to emit light by a voltage charged in a main capacitor from a power supply battery.

[0003]

Thus, in the film-integrated type camera having the strobe device as described above, an actual flat screen camera 4-12
The device disclosed in Japanese Patent No. 0960 is miniaturized by disposing a main capacitor in the upper part of the film chamber and a power supply battery in the lower part of the optical path of the lens so that their longitudinal directions are parallel to the film feeding direction. The main capacitor has been arranged in the lower part of the optical path of the lens so as to be parallel to the film feeding direction, and the power supply battery has been arranged beside the spool chamber perpendicularly to the film feeding direction to reduce the size.

By the way, in the case of further miniaturization of the camera for easy carrying, resource saving, cost reduction, etc., when the power supply battery is arranged vertically to the film feeding direction, the vertical length of the camera is increased. Does not become smaller due to the height of the battery, and if the main condenser is placed in the upper part of the spool chamber so that the longitudinal direction is parallel to the film feeding direction, the viewfinder and release mechanism are arranged when the horizontal direction of the camera is shortened. I can't take up space.

On the other hand, in a conventional film-integrated camera having a strobe device, an AA battery is used due to problems such as the charging time of the strobe device. The size and weight of the camera are greatly affected by the power supply battery and the main capacitor of the strobe device, which are relatively large in shape.

[0006] In the pursuit of downsizing and weight saving of the camera for easy carrying and resource saving, the size of the AA dry battery as the power source battery and the main capacitor of the strobe device became a problem. Further, if the power source battery is changed to the AAA dry battery with the conventional strobe device, the charging time becomes long. Further, if the F number of the photographing lens used conventionally and the guide number of the strobe device are lowered, the reaching distance of the strobe light becomes short.

The present invention has been made in view of the above point, and the inventions according to claims 1 and 2 are further miniaturized by improving the arrangement of the main capacitor and the power supply battery of the strobe device. It is intended to provide an integrated camera. It is another object of the present invention to provide a film-integrated camera which is equipped with a strobe device and which can be further reduced in size and weight for easy carrying and resource saving. .

[0008]

In order to solve the above-mentioned problems and to achieve the object, the invention according to claim 1 is a strobe device for causing a discharge tube to emit light by a voltage charged in a main capacitor from a power supply battery. In the film-integrated camera in which the film cartridge is preloaded at the time of assembling, the longitudinal direction of the main condenser and the power supply battery is arranged below the lens optical path of the taking lens so as to be parallel to the film feeding direction. I am trying.

It is characterized by using AAA batteries.

According to a fourth aspect of the present invention, in the film-integrated camera, the guide number of the strobe device is 9 or less,
In addition, it is characterized in that the capacity of the main capacitor is 120 μF or less.

According to a fifth aspect of the present invention, in the film-integrated camera, the guide number of the strobe device is 9 or less,

FIG. 3 is an exploded perspective view of a film-integrated camera.

The film-integrated camera 1 is a simple camera that is commercially available with a photographic film loaded, and the photographic film is loaded in the camera assembling process so that the user can load or rewind the photographic film. Since the operation of is unnecessary, the user can immediately take a picture.

The film-integrated camera 1 includes a main body 2

A photographic film F wound around a spool 9 is stored in the film roll chamber 7, and the photographic film F is wound around a film cartridge 8 by a winding mechanism 10 at the time of photographing.

The hoisting mechanism 10 is composed of a hoisting knob and the like (not shown), is arranged from above the cartridge chamber 6 to above the photographing frame 5, and a photographing lens 11 is provided on the front side of the photographing frame 5. . A finder 12 is arranged above the photographing frame 5.

The film-integrated camera 1 is equipped with a strobe device 13. The strobe substrate 14 of the strobe device 13 is attached to the front side of the film roll chamber 7. A circuit element 15 is wired on the strobe substrate 14, and a discharge tube 16 is connected to an upper position thereof, and the discharge tube 16 faces a strobe window 17 of the front cover 3. Further, a main capacitor 18 is connected to a position below the strobe board 14, and a power battery 19 is connected to the strobe board 14 by a lead plate 20. Power battery 1

Further, when the size and weight of the film-integrated camera 1 are sought, the size of the power supply battery becomes a problem. Therefore, the size and weight of the film-integrated camera 1 can be reduced by using a small and relatively inexpensive AAA battery. ing.

If AAA batteries are used as the power source battery, the charging time of the main condenser 18 of the strobe device 13 becomes long, so the guide number of the strobe device 13 is lowered to 9 to 5.5, and the main condenser 18 is reduced. By setting the capacity of 120 μF to 50 μF, the charging time can be shortened. Set the capacity of the main capacitor 18 to 1
When the size is set to 20 μF to 50 μF and the AAA dry cell is used, about 80 μF is preferable in view of the charging time of the main capacitor 18.

If the guide number of the strobe device 13 is lowered to 9 to 5.5, the reaching distance of the strobe light when using the strobe becomes short. Therefore, the F of the shooting lens
By setting the value to 9 to 5.6 and making it brighter, the possible shooting distance when using the flash was extended.

When the F-number of the taking lens is increased,
Since overshooting during daytime shooting is possible, the strobe device 13 is configured to switch the shutter speed and aperture between the used state and the unused state. The shutter speed switching value is
The shutter speed SV when the strobe is not used is ISO400
Is about 1/100, the shutter speed SV when using a strobe is about 1/60, and the F value when switching the aperture is about 10.5 when the strobe is not used.
An aperture F value of about 8 when using a flash is desirable. Also, I
For a photographic film of SO800, it is desirable to set the aperture F value to about 14 to 15 when the strobe is not used. This makes it possible to remedy undershoot when shooting with a flash and overshoot when using a flash.
