Abstract

PURPOSE:To enlarge and photograph a small object at a close position by closely fixing the focusing position of a photographing lens and setting high magnification. CONSTITUTION:The photographing lens 4 whose focusing position is fixed to a close point and which has the high magnification is incorporated in a camera main body 1. After focusing is performed by recognizing a main body 1, taking an object A through a finder 6 and separating from an object A by a specified distance, a shutter releasing button 2 is depressed. In such a case, a stroboscopic light emission part 8 is allowed to emit light by a changeover switch X.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disposable type film-integrated camera.

[Conventional technology]

Generally, this type of film-integrated camera is constructed by incorporating various photographing functions such as a lens, a shutter release button, and a winding mechanism into a housing in which film is loaded in advance. Since the camera has the characteristics of being small and lightweight and is extremely inexpensive, it has rapidly become popular as a simple disposable camera.

With the spread and expansion of such film-integrated cameras, the need for higher functionality has begun to emerge in recent years. That is, it has become desirable to have a film-integrated camera that has advanced functions such as strobe photography, zooming photography, and wide-angle photography. However, these advanced features are simple and
This is incompatible with the characteristics of film-integrated cameras, which are low cost and versatile, and various development issues have emerged.

[Problem to be solved by the invention]

In order to achieve both the above-mentioned sophistication of photographic functions and the simplicity and low cost that are the characteristics of film-type cameras, it is conceivable to configure the camera as a specialized type of simple camera whose use is limited to specific fields. .

For example, close-up photography that takes macro shots of flowers, insects, still life, etc., belongs to a relatively special type of photography.
On the other hand, it is also an attractive field that doubles the fun of photography. A typical film integrated camera is a disposable type that uses about 10 to 30 frames of film, so if it can be applied to such fields, its convenience will be greatly improved. However, in order to perform close-up photography, a photographic lens must be installed in a macro system, and conventional film-integrated cameras cannot perform such photography.

In view of the above points, it is an object of the present invention to provide a film-integrated camera exclusively for macro photography.

[Means to solve the problem]

In order to achieve the above object, the film-integrated camera of the present invention has a configuration in which the focus position is fixed at close range and is equipped with a photographing lens with a high magnification setting, so that small objects at close positions can be magnified and photographed. It is something.

〔Example〕

Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings.

Figure 1 is an overall perspective view of the film-integrated camera of the present application, Figure 2
Figures (a) and (b) are explanatory diagrams showing the relationship between the subject and the photographic lens, and Figure 3 is a sectional view of the camera body.

In the figure, reference numeral 1 denotes the camera body of the film-integrated camera of the present invention, and the zero body 1 is constructed of a plastic housing, and is provided with a spool chamber S, a battlerone chamber P, and a film F inside. By covering the zero body 1 with a paper carton printed with a predetermined design, a suitable appearance as a disposable camera can be obtained.

Reference numeral 2 denotes a shirt release button, and this button 2 is provided at a suitable position on the upper surface of the main body 1, and is capable of triggering a charged-up shutter (not shown).

Reference numeral 3 denotes a winding knob, and the winding knob 3 is provided on the back surface of the main body 1 (on the photographer's side) so that a portion thereof protrudes.

Reference numeral 4 denotes a photographing lens. The photographing lens 4 is made up of a unit that can be attached to the zero body 1, and its focus position is fixed at a nearby point and is set at a high magnification.

That is, as shown in FIG. 2(a), the camera is configured to take a close-up photograph of the subject A several centimeters to several tens of centimeters in front at a magnification of, for example, 1 to 10 times.

The photographing lens 4 is configured in a barrel so that the entire lens unit can be extended using, for example, a lead mechanism.
The photographing magnification may be selected in several stages.

5 is a counter indicating the number of remaining films.

Reference numeral 6 denotes a finder, and the finder 6 consists of a transparent through hole provided at a suitable position on the upper part of the zero body 1. The finder 6 is configured such that the focus position is the center of its field of view, and its visual axis intersects the photographing optical axis at a larger angle than in a normal film-integrated camera. .

Reference numeral 8 denotes a strobe light emitting section, and the strobe light emitting section 8, including its peripheral circuit 8a, is disposed in a flat space formed by the difference in depth between the Subur room S and the Batrone chamber P of the main body 1 (
Figure 3). The strobe light emitting unit 8 changes its direction and the shape of its reflector as appropriate so that the focus position falls within its irradiation area. Also, it is desirable to configure the irradiation area to be a rectangle that exactly matches the image frame on the film surface, but since the distance to subject A is short, the amount of irradiation light may be small, resulting in a low guide number. There is. Thereby, it is possible to save the strobe light of the light emitting section 8 (and the capacity of its peripheral circuits).

Note that the strobe light emitting unit 8 is rotated around the rotation axis J as shown in FIG. 2(b).
It may be configured to be rotatable around the center, and the light projection angle may be changed as appropriate. 9 is a battery compartment, and X is a strobe changeover switch.

In the above embodiment, the photographer grasps the zero body 1 of the film-type camera of the present invention and captures the subject A through the finder 6. Then, set the photographic lens 4 so that it is separated from the subject A by a preset distance, adjust the focus,
Press shutter release button 2. At this time, the strobe light emitting section 8 can also be caused to emit light by the changeover switch X. As a result, the subject A is magnified by a predetermined magnification, and an image is formed on the surface of the film F, allowing close-up and enlarged close-up of small objects much easier than macro photography with a single-lens reflex camera.

〔Effect of the invention〕

As described above, the film-integrated camera of the present invention is characterized by being equipped with a photographing lens whose focus position is fixed at a close position and set at a high magnification, so that small objects at a close position can be photographed in an enlarged manner.

As a result, even ordinary photographers who are not proficient in the photographic technique can easily take close-up photographs, which has the excellent effect of opening up new fields of application for film-integrated cameras. .
