Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data imprinting device for a camera whose photographing screen size can be changed.

[0002]

2. Description of the Related Art In recent years, many cameras for taking panoramic photographs have been released. This camera for panoramic photography usually creates a horizontally long screen size by blocking a part of the shooting screen size such as 35 mm film in the up and down direction with a mask, and enlarges and prints the filmed film in a pseudo manner. This is a camera for paramount photography. Full-size (normal screen size: 2
4 x 36 mm) and panoramic screen size (13 x 36 m
A camera that can switch m) has also been released.

On the other hand, there is a camera provided with a data imprinting unit that imprints data such as the photographing date on the edge of the screen, and this camera is widely used. In addition, the actual development Sho 55-1334
No. 30 and Japanese Utility Model Laid-Open No. 55-133431 describe a data imprinting device for a camera that selectively imprints data such as characters at different positions on the film surface in the same size. Furthermore, JP-A-62-103625, JP-A-63-139327, and JP-A-63-139.
Japanese Patent No. 328 describes a data imprinting device for a camera that selectively imprints data at different positions on a film surface by using light emitting members of different sizes.

[0004]

In the above-mentioned camera capable of switching between the full size and the panoramic screen size, data such as the shooting date is dropped from the screen when the panoramic screen size is shot. Then, leaving the data such as the shooting date imprinted on the screen is not considered.
In the data imprinting device of the camera described in Japanese Utility Model Laid-Open No. 55-133430 and Japanese Utility Model Laid-Open No. 55-133431, the data such as characters are selectively made the same at different positions on the film surface. Since the image is imprinted in the size, there is a problem that the characters and the like on the print are not properly sized in the panoramic screen size in which the enlargement ratio at the time of printing is larger than that of the full size.

Further, in the data imprinting device of the camera described in the above-mentioned JP-A-62-103625, JP-A-63-139327, and JP-A-63-139328, different sizes are used. Since the data is selectively imprinted at different positions on the film surface by using the light emitting member, there is a problem that the configuration is complicated due to the need for a plurality of light emitting members.

The present invention solves the above-mentioned drawbacks and provides a data imprinting apparatus for a camera having a simple structure capable of imprinting data on a film in an appropriate size in both a normal screen size and a panoramic screen size. The purpose is to
