Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera equipped with a magnetic head which uses a photographic film having an exposure / photographing section and a magnetic recording section and performs recording / reproducing with respect to the magnetic recording section.

[0002]

2. Description of the Related Art In recent years, a silver salt film having a conventional exposure photographing section and a magnetic recording section capable of magnetically recording photographing data such as exposure data, camera model data and date data on a film surface is used. A camera has been proposed in which shooting data is recorded in an exposure shooting unit corresponding to a shot screen by a magnetic head. Various usages of the photographed data are conceivable, such as when the film is printed at a developing station or when the film is filed.

[0003]

In the above-mentioned conventional camera, when the film is photographed and fed, the film is wound from the patrone (forward) and the film is rewound into the patrone. There are two types: (reverse feed). The magnetic recording on the film is performed during the feeding operation of one frame after shooting.

For this reason, the camera has two types of forward feed and reverse feed.
Even if the feeding can be performed in any direction, if one magnetic head is fixed at a predetermined position, shooting data may not be recorded on the corresponding shooting screen depending on the feeding direction.

When a film used halfway is loaded, if the shooting direction (feeding direction) used before is ignored and shooting is performed, the shooting order is confused in one film. .

Further, when a film that has been used up to the middle is loaded into a camera of the type that is always forward or reversely fed,
If the feeding direction of the camera is opposite to the previously used feeding direction of the film, there is the problem that double-shots will occur.

An object of the present invention is to provide a camera capable of performing proper exposure photographing and magnetic recording without being influenced by the film feeding direction.

[0008]

To achieve the above object, in a camera using a photographic film having an exposure photographing section and a magnetic recording section, the first means of the present invention is to photograph in the film feeding direction. A pair of magnetic heads installed with respect to the magnetic recording unit at positions substantially symmetrical with respect to the screen,

A second means is to use a photographic film, and a pair of magnetic heads installed on the magnetic recording section in the camera in the film feeding direction at positions substantially symmetrical with respect to the photographing screen. A feeding means that allows one screen to be taken in the direction of winding from the patrone and in the direction of rewinding to the patrone, and recording in a magnetic recording unit read by a magnetic head when a photographic film taken halfway is loaded. It is characterized by further comprising: a determining means for determining a film feeding direction for continuing the photographing based on the obtained information, and a switching means for switching a magnetic head to be used according to the determined film feeding direction.

A third means is the above camera, which is provided with a pair of magnetic heads installed on the magnetic recording portion at positions substantially symmetrical with respect to the photographing screen in the film feeding direction. The magnetic head on the winding side in the film feeding direction is used as a recording head, and the magnetic head on the sending side is used as a reproducing head.

The fourth means detects whether or not data is recorded in the magnetic recording section by the reproducing head in the above-mentioned third means, and when the data is recorded, the corresponding feeding means takes a picture. It is characterized in that the recording head is provided with control means for recording the photographing data on the magnetic recording section of the photographing screen after the photographing is completed when the screen is idly fed and is not recorded.

A fifth means is characterized in that, in the above-mentioned fourth means, all the photographic film can be wound around the cartridge in the state where the final photographing portion exists.

A sixth means is an exposure photographing section, a magnetic recording section provided corresponding to a photographing screen, and a film state magnetic recording at least film presence / absence and film state information of a film feeding direction. In a camera that uses a photographic film having a recording section, and also takes pictures one by one while rewinding the photographic film in a cartridge, the magnetic recording section is provided at a position substantially symmetrical with respect to the shooting screen in the film feeding direction. A pair of magnetic heads installed opposite,
Switching means for switching the magnetic head to be used for recording or reproduction, and the photographing data recorded in the magnetic recording section by the magnetic head when a photographic film photographed halfway is loaded, and one screen before the photographed screen is read. And a feeding means for preliminarily winding up to the photographing screen.

A seventh means is the above-mentioned sixth means, wherein the photographing data recorded in the magnetic recording portion of the photographed screen is read at the time of reading the information recorded in the film state magnetic recording portion and at the time of preliminary winding. When reading, the magnetic head on the cartridge side is used as a reproducing head, and at the time of film feeding after photographing, the magnetic head on the cartridge side is used as a recording head to record photographing data.

An eighth means is the above sixth means, wherein when the film-state magnetic recording section is in the non-recording state, the magnetic head on the side opposite to the cartridge is used as a recording head for the film-state magnetic recording section. It is characterized in that the information on the film feeding direction is recorded at the time of winding.

[0016]

According to the above-mentioned first means, since the two magnetic heads can be switched and used by the switching means in accordance with the film feeding direction, either forward feeding or reverse feeding by the feeding means can be performed. On the other hand, magnetic recording can be surely performed on a predetermined magnetic recording portion.

According to the second means, even if the loaded photographic film is already used halfway, the feeding direction at the time of the previous photographing is judged by the judging means based on the already recorded information. And fed in the same direction, but first
Since the magnetic heads can be switched and used by the switching means like the above means, magnetic recording can be surely performed on a predetermined magnetic recording portion.

According to the third means, since the reproducing head can read the photographing data of the next photographing screen while recording the photographing data by the recording head, the re-exposure to the next photographing screen which has been photographed by mistake ( Double shooting) is prevented.

According to the fourth means, by the control means, the photographing screen in which the photographing data is recorded in the magnetic recording portion is fed in a blank manner, and only the non-photographing screen having no data in the magnetic recording portion can be photographed. Since the feeding and recording control are performed as described above, double photographing is prevented regardless of the difference in film feeding.

According to the fifth means, since the photographic film can be taken out from the camera at an arbitrary number of shots, it is possible to use various kinds of films while exchanging several frames by one camera, and to use one film. The film can be used in cameras with different capabilities.

According to the sixth means, when a photographic film which has been used up to the middle is loaded, if there is data in the magnetic recording portion by the magnetic head, this portion is judged as used and only the unused portion is used. Since it is possible to prevent the camera from being pulled out from the cartridge, it takes less time to prepare for shooting, and even if the camera back cover is opened while pulling out from the cartridge, the used (shooting) film part is exposed. It will not be lost.

According to the seventh and eighth means, the magnetic head is switched between the recording head and the reproducing head as needed, and the magnetic head for the recording / reproducing operation in the sixth means is used. The configuration can be simplified.
