DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a photograph with a date and time of photographing, a photograph of an observation record of a plant or an insect in which a place is photographed, and a commented photograph in which a handwritten character or picture is photographed.
The present invention relates to an adapter for imprinting information on a film unit with a lens, which enables production of postcards, picture diary photographs, and the like.

[0002]

Recently, there has been proposed a film unit with a lens which does not require loading of a photographic film and which can easily take a photograph. In general, a film unit with a lens is a patrone in which a photographic film is housed in a box-shaped unit body having a strobe device, a film winding mechanism, and the like in addition to a simple photographing mechanism including a photographing lens, an optical finder, a shutter, and the like. Is built in. The user who has purchased the film unit with the lens does not need to perform a troublesome operation such as hooking the film on the film winding mechanism after mounting the patrone in the camera when shooting because the patrone is already built-in. Simply point the lens at the subject and press the shutter. And after the shooting,
Instead of taking out the photographed photo film, the unit itself can be taken out directly to the developing dealer, and there is no need to perform a troublesome operation such as rewinding the film or taking out the patrone.

[0003] As described above, a film unit with a lens can easily take a photograph without troublesome operations. For example, when observing plants and insects as part of extracurricular activities in the lower grades of elementary school, these plants, It can be used to photograph insects and the like.

When photographing plants, insects, and the like as observation records, it is necessary to record the photographing date, photographing location, and the like. Very convenient. In order to respond to such a demand, for example, it is conceivable to equip a film unit with a lens with optical information imprinting means for imprinting information such as the photographing date and the like optically, but this increases the cost. Above, the information projected by the optical information projection means is limited to the date, etc., and the lens has only the minimum functions necessary for shooting, reducing the manufacturing cost and making it disposable There is a problem that the result is contrary to the original purpose of the attached film unit.

In addition, instead of equipping the film unit with the lens with optical information imprinting means, a transparent film in which information such as the photographing date, photographing location, etc. is written on the photographic paper is exposed when developing after photographing. A method is known in which various information (pictures, handwritten comments, etc.) in addition to the shooting date, shooting location, and the like are transferred to a photograph by operating the operation, but the operation is cumbersome and time-consuming. For a person who does not have a developing facility, there is a problem that a developer must request a developing dealer.

The present invention has been made in view of the above circumstances, and does not increase the cost. In addition to information such as the photographing date, the photographing location, etc., it is possible to easily print a handwritten character or picture. It is an object of the present invention to provide an adapter for imprinting information on a film unit with a lens that can be used.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a film unit equipped with a lens which is detachably attached to a camera, and is capable of not only providing information such as a photographing date, a photographing place, but also a handwritten character or picture.

After the preparation as described above, the photographic film is wound by operating the film winding mechanism 14, the object to be photographed is captured in the fields of view of the viewfinders 27 and 42, and the shutter 13 is pressed.

According to the information imprinting adapter of this embodiment, the lever 35 is operated to operate the close-up lens 3.
By switching between 1, 32, etc., it is possible to set a shooting mode in which information such as a shooting location is imprinted, a close-up shooting mode, and a normal shooting mode.

Further, in the film unit with lens 10, the focal length of the photographing lens is constant and cannot be adjusted, and the film unit with lens 10 itself must be brought into contact with and separated from the subject. With the close-up lens 32, the depth of field is very shallow, and it is difficult to accurately adjust the focal length. However, in this embodiment, when the cover member 50 is opened, the holding arm 51 moves the focus of the close-up lens 32. Since the subject is in contact with the holding arm 51, the focal length is adjusted so that close-up photography can be performed without defocusing.

Further, normal photographing can be performed even when the adapter main body 20 is attached to the lens-fitted film unit 10, and it is not necessary to remove the adapter main body 20 each time, which is convenient.

[0034]

As described above, according to the information imprinting adapter of the film unit with the lens of the present invention, the lens member having the close-up lens for shortening the close-up distance at which the image can be partially photographed is used as the lens holder. The lens-equipped film is provided with a cover arm rotatably equipped with a holding arm for slidably mounting the card piece on which the information to be imprinted is written within the focal length of the close-up lens. Costs are reduced without having to install optical information imprinting means in the unit, or performing complicated development processing such as exposing a transparent film on which printed characters or the like are printed on photographic paper. Information such as the date and time of shooting, location, handwritten characters, pictures, etc. can be imprinted without knowing.
