Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data imprinting apparatus for a camera and a camera for exposing data such as date on a photographic film, and more specifically, data applicable to a camera capable of switching between standard size and panoramic size. Regarding the imprinting device.

[0002]

2. Description of the Related Art Conventionally, a camera data imprinting device using a liquid crystal display (liquid crystal shutter) is mounted on the back of a film 2 in a back cover 1 of a camera, as shown in FIG. The number string of the date data is exposed on the back side of. The data imprinting device is about 3c vertically and horizontally
For example, a tungsten lamp 3a, which is a light source, and light emitted from the tungsten lamp 3a and traveling along the plane of the case are reflected at a right angle and deflected in the thickness direction of the case in a resin case having an outer shape of m and a thickness of about 3 mm. It has a reflection plate 3b, a transmissive liquid crystal display 3c illuminated by its reflected light, and a light-shielding plate 3d for limiting the illumination range of this display, and the like is formed as a data character string on the display 3c. The transmitted light thus obtained is directly projected onto the back surface of the film 2.

As disclosed in Japanese Patent Laid-Open No. 63-139327, the screen size is standard size (36 mm × 24 mm) and half size (36 mm).
There is known a data imprinting device that can be adapted to a camera that can be switched to × 13 mm). Although this data imprinting device has a half-size area that is 1/2 of the standard size, the imprinted data occupies the same area when printed, so the standard liquid crystal display and characters of a different size are used. This is a line-up of liquid crystal displays for halves that form rows. Therefore, even if the print magnification changes, the area occupied by the imprinted data is reduced on the negative film, so even if it is half size,
The area ratio of the imprinted data on the print can be made equal to that of the standard size. Therefore, it is possible to display data in which the character balance is appropriate without causing any discomfort.

[0004]

In recent years, the screen size is standard size (36 mm x 24 mm) and panoramic size (36 mm x 13 m).
Cameras that can be switched to m) are gaining popularity. This type of camera mechanically hides the upper part (about 5.5 mm width) and the lower part (about 5.5 mm width) of the standard film size with a light shielding plate during panoramic shooting, and an elongated panorama size (in the center part) 36mm x 13mm) is limited. A standard size negative is printed as a service print plate with a length magnification of about 4 times, but since the panorama print plate has two service print plates side by side, the panorama size negative has a length magnification ratio of about 8 Doubled and printed as a panoramic print version.

Even in such a camera capable of switching between the standard size and the panoramic size, there is a strong demand for incorporating a data imprinting device. However, the data imprinting device in the camera capable of switching between the standard size and the half size cannot be applied as it is. To obtain a service print plate from a half size negative, the length magnification is 4 × 2 ^0.5 ≈5.6 times, whereas to obtain a panorama print plate from a panorama size negative, the length magnification is It is about 8 times. The print size of the panoramic size is ^20.5 times that of the half size and about twice that of the standard size. Therefore, as in the case of the half size described above, it is necessary to reduce the imprinted data character string in advance compared to that of the standard size, but the size of the data character string imprinted on the panoramic size film. Since the area is enlarged to about 64 times, it is necessary to consider the sharpness of the character string in addition to the optimization of the size of the character string. Even with the recent improvement in film performance (ultra-fine graining), if the enlargement ratio at the time of printing is too large, the blurring or thinning of the outline of the data character string becomes apparent, and the character display quality deteriorates. Further, in the case of panoramic photography, the upper and lower parts of the film are hidden by the light-shielding plate, and therefore the position where the character string is to be imprinted must be on the center side of the film.

In order to suppress the blurring of the data character string, the divergence angle (irradiation angle) of the illuminating light beam from the light source to the liquid crystal display body is made as small as possible and the liquid crystal display body is illuminated with a light beam close to a parallel light flux. However, in order to reduce the viewing angle of the liquid crystal display from the light source, the optical distance between the light source and the liquid crystal display must be set long.

However, the data imprinting device is generally mounted in the back cover of the camera and has a length and width of about 3 cm and a thickness of 3 mm.
Since it is a module of a certain degree, setting the optical path lengths of both the standard size illumination system and the panoramic illumination system to a large length is an obstacle to compactness.

Therefore, in view of the above problems, the present invention proactively provides light reflecting means in independent illumination systems for standard size and panorama to equivalently set the optical path lengths of both illumination systems to be long. Another object of the present invention is to provide a data imprinting device for a camera capable of suppressing blurring of a data character string after a panorama size print and enabling a compact structure.

[0009]

In order to solve the above problems, the present invention provides a first light source, a first reflector for reflecting light emitted from the first light source in the thickness direction of the device, and a first reflector for receiving the reflected light. A standard size data imprinting optical system having one transmissive liquid crystal element array, a second light source, a second reflecting plate for reflecting light emitted from the light source in the thickness direction of the apparatus, and a second reflecting plate for receiving the reflected light. a data imprinting device for a camera and a data imprinting optical system for panorama size having a light transmitting type liquid crystal element array, the first and second light transmission type liquid crystal
Short side direction defined as the direction in which the short side of the element array extends
In, the first transmissive liquid crystal element array is arranged outside the second transmissive liquid crystal element array with respect to the center of the device in the short side direction , and the first transmissive liquid crystal element array and the second reflective liquid crystal element The directions of incident light with respect to the reflecting plate are antiparallel to each other, and the light traveling on the plane of the device is guided between the optical paths of the first light source and the first reflecting plate of the standard size data imprinting optical system. It is characterized in that a deflecting means for deflecting the light in a plane and introducing it into the first reflecting plate is provided.

As described above, the first and second transmissive liquid crystal elements
In the direction of the short side specified as the direction in which the short side of the child row extends
Oite, first light transmission type liquid crystal element array distribution outside with respect to the short side direction center of the apparatus than the second light transmission type liquid crystal element array
Is location, conversely, for the second light transmission type liquid crystal element array disposed inside relative to the short side direction center of the apparatus than the first light transmission type liquid crystal element array, in case of the panoramic photographing Allows data to be imprinted without the second transmissive liquid crystal element array being hidden by the light shielding plate. Further, the directions of the incident light with respect to the first reflecting plate and the second reflecting plate are made antiparallel to each other, and the light traveling on the device plane is deflected in the plane between the optical paths of the standard size data imprinting optical system. Since the deflecting means is provided, the deflecting means detours the optical path and increases the optical path length, so that the device can be made compact and the diffusion angle of both data imprinting optical systems can be suppressed. Here, it should be noted that the deflecting means is essentially unnecessary unless the device is made compact, but under a limited device space (device plane area), the light source, the reflecting mirror, and the liquid crystal The imprinting system consisting of the element array cannot be freely arranged. The problem is whether to interpose a deflecting means that substantially secures the optical path length in the panorama size data imprinting system or to interpose the deflecting means in the standard size data imprinting system. Also, it should be taken into consideration that the diffusion angle of the illumination light flux increases due to the mounting accuracy. Since the panorama size has a higher print magnification than the standard size, it is necessary to suppress the diffusion angle as much as possible. From this point of view, in the data projection system for panorama size, the light source and the direct illumination light from this are introduced to the second reflecting mirror without using the deflecting means. Further, in the standard size imprinting system, the precision of the diffusion angle is relatively low, so that the device is made compact by interposing the deflecting means.

The long sides of the first and second transmissive liquid crystal element arrays are
In the long side direction defined as the stretching direction, the first

By setting the side closer to the center of the long side direction, the data position of the panoramic size and the data position of the standard size on the print can be adjusted to substantially the same position.

Further, the present invention is a standard size data imprint having a first light source, a first reflecting means for reflecting light emitted from the first light source, and a first transmissive liquid crystal element array for receiving the reflected light. An optical system, a second light source, a second reflecting means for reflecting light emitted from the second light source, and a panorama size data imprinting optical system having a second transmissive liquid crystal element array for receiving the reflected light. In addition, the standard size data imprinting optical system is provided above the panorama size data imprinting optical system. Since the second transmissive liquid crystal element array of the panorama size data imprinting optical system is located below the first transmissive liquid crystal element array of the standard size data imprinting optical system, the central portion of the film Therefore, data can be imprinted on the horizontally long panorama size area in the center of the film. In such a configuration, there is provided means for switching between the light of the standard size data imprinting optical system and the light of the panorama size data imprinting optical system, and the operating means of the means for switching is a manual switch. Also,
When the light of the standard size data imprinting optical system and the light of the panoramic size data imprinting optical system are imprinted on the film, there is provided means for preventing the light of the panoramic size data imprinting optical system from imprinting on the film.

Here, the projection optical system for panorama size is arranged on a straight line from the lower left to the upper left of FIG. When the illumination light beam is deflected, the precision of the diffusion angle deteriorates due to the assembling precision of the deflection means, so the illumination light from the tungsten lamp 51 is introduced into the reflecting mirror 52 without being bent. Therefore, the data character string for the panorama size is clear without blurring or thinning. On the other hand, in the standard size data imprinting optical system, reflecting mirrors 62 and 63 as deflecting means are interposed. This constitutes a retrodirective mirror that shifts the light beam emitted from the tungsten lamp 61 by the distance L and moves backward. This is for the purpose of diverting light rays around the apparatus to make the apparatus compact and for ensuring an optical path length and forming a parallel light flux as much as possible. If the two reflecting mirrors 62 and 63 are mutually fixed at a right angle, it is possible to obtain a highly accurate anti-parallel reflected light beam with respect to the incident light beam. Also, the assembly accuracy is rough. The tungsten lamp 61 is mounted in a stacked state on the liquid crystal display bodies 50 and 60. This point also contributes to downsizing of the device.
