DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a device 及 imprinting camera for data to exposure data such as date to shoot film
More particularly, the present invention relates to a data printing apparatus applicable to a camera that can be switched between a standard size and a panoramic size.

[0002]

2. Description of the Related Art Conventionally, a data writer for a camera using a liquid crystal display (liquid crystal shutter) is mounted on the back of a film 2 in a camera back cover 1 as shown in FIG. Is exposed to a numerical string of date data. The data imprinting device is about 3c vertically and horizontally.
For example, in a resin case having an outer shape of about 3 mm in thickness, a tungsten lamp 3a as a light source, and light emitted from the light source and traveling along the plane of the case is reflected at right angles to be deflected in the thickness direction of the case. It has a reflective plate 3b, a transmissive liquid crystal display 3c illuminated by the reflected light, and a light-shielding plate 3d for limiting the illumination range of the display. The display 3c forms a data character string. The transmitted light is projected on the back surface of the film 2 as it is.

As disclosed in JP-A-63-139327, the screen size is set to a standard size (36 mm × 24 mm) and a half size (36 mm × 36 mm).
A data imprinting device compatible with a camera switchable to (× 13 mm) is known. This data imprinting device uses a standard liquid crystal display and characters of a different size to equalize the area occupied by imprint data when printed, although the half-size area is half the standard size. The liquid crystal displays for half forming a line are arranged in a line. Therefore, even if the print magnification changes, on the contrary, the area occupied by the imprint data on the negative film is reduced, so it can be said that it is half size,
On a print, the area ratio of the imprint data can be made equal to that of the standard size. Therefore, it is possible to perform proper data display of character balance without a sense of discomfort.

[0004]

In recent years, the screen size has been changed to a standard size (36 mm × 24 mm) and a panoramic size (36 mm × 13 m).
Cameras that can be switched to m) are gaining in popularity. This type of camera mechanically hides the upper part (approximately 5.5mm width) and lower part (approximately 5.5mm width) of the standard film size with a light-shielding plate during panorama shooting, and has an elongated panoramic size ( 36 mm x 13 mm). A standard size negative is printed as a service print plate at a length magnification of about 4 times, but a panoramic print plate is a size in which two service print plates are arranged side by side. Printed as a panoramic print version at 2x.

There is a strong demand for a camera that can switch between the standard size and the panoramic size, as well as to incorporate a data recording device. However, the above-described data imprinting device in a camera that can switch 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, whereas to obtain a panoramic print plate from a panoramic-size negative, the length magnification is about 8 times. It is twice. The print magnification of the panorama 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 size of the data character string to be imprinted beforehand in comparison with that of the standard size. Since the area is enlarged by about 64 times, the size of the character string needs to be considered in addition to the optimization of the size of the character string. Even under recent improvements in film performance (ultra-fine graining), if the enlargement magnification at the time of printing is too large, blurring or thinning of the outline of the data character string becomes apparent, resulting in deterioration of character display quality.

In order to suppress the blurring of the data character string, it is necessary to minimize the diffusion angle (expected angle of irradiation) of the illuminating light beam from the light source to the liquid crystal display, and illuminate the liquid crystal display with a light beam close to a parallel light beam. However, in order to reduce the angle at which the liquid crystal display is viewed 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 is about 3 cm in length and width and 3 mm in thickness.
Since these modules are of the order of magnitude, setting the optical path lengths of both the illumination system for the standard size and the illumination system for the panorama to be long becomes an obstacle to downsizing.

In view of the above-mentioned problems, the present invention provides an independent illumination system for a standard size and a panorama, in which light reflecting means is actively provided, and the optical path lengths of both illumination systems are equivalently set to be longer. Another object of the present invention is to provide a camera data imprinting apparatus that can suppress blurring of a data character string after a panoramic size print and can realize a compact configuration.

[0009]

The projection optical system for the panorama size is arranged on a straight line from the lower left to the upper left in FIG. If the illuminating light beam is deflected, the accuracy of the diffusion angle is degraded due to the assembly accuracy of the deflecting means. Therefore, the illuminating light from the tungsten lamp 51 is introduced into the reflecting mirror 52 without bending. For this reason, the data character string for the panorama size is clear without blur or thinning. On the other hand, the standard size data imprinting optical system has reflecting mirrors 62 and 63 as deflecting means. This constitutes a retroreflective mirror that shifts the light beam emitted from the tungsten lamp 61 backward by shifting it by a distance L. This is for the purpose of diverting light rays around the device for the purpose of making the device compact, and for forming a parallel light beam as much as possible while securing the optical path length. If the two reflecting mirrors 62 and 63 are fixed to each other at right angles, a highly accurate anti-parallel reflected light can be obtained with respect to the incident light. Also, the assembly accuracy is rough. The tungsten lamp 61 is mounted on the liquid crystal displays 50 and 60 in a stacked state. This point also contributes to downsizing of the device.
