FIGS. 3 and 4 are a vertical sectional view around the data imprinting portion in a panorama size photographing state of the camera and a diagram showing an operation state of the mask switching drive portion viewed from the film side. As shown in FIG. 1 and FIG. 3, the camera has a data imprinting unit having a built-in imprinting optical system, and a mask switching drive unit for trimming a normal size and panorama size shooting screen.

The above-mentioned imprinting part is supported by the camera body 10 and houses a case 1 for accommodating the imprinting optical system;
It comprises an LED 2, which is a light source unit of imprint data, which constitutes an imprint optical system, and a separator lens 3. The LED 2 serving as the light source unit may be an LCD having a backlight. The case 1 has a cylindrical shape, and the LED 2 is mounted on the rear opening 1a side so as to emit light toward the front.
Further, on the side of the front opening 1b, the single separator lens 3 for guiding the light emitted from the LED 2 in two directions and further forming an image on the image forming surface of the film 11 is held.

The separator lens 3 separates the projected light emitted from the LED 2 into two optical paths and guides the separated light. One is a lens portion 3a for forming a normal-sized projected data and a lens portion 3a. The other is formed by a lens unit 3b for imaging panorama size imprint data. On the other hand, the camera body 10 has projection openings 10a and 10b of the camera body 10 at data projection positions corresponding to a normal photographing screen and a panoramic photographing screen, that is, a screen without trimming and a screen to be trimmed. Is provided. The lens portions 3a and 3b of the separator lens 3 are respectively provided with a projection opening 10 of the main body 10.
a, 10b. Further, as described later, in order to perform imprinting while the film 11 is running, the imprinting opening 10a or 10b provided in the main body 10 is provided on the side of the main body aperture 10c in the film running direction. (See FIGS. 2 and 4).

As shown in FIGS. 2 and 4, the mask switching drive section mainly includes a photographing screen size operation lever 4 and upper and lower panorama masks 5 and 6. The size operation lever 4 has a fork portion 4 a and is supported by a rotating shaft 7. And it is rotated manually or electrically. A drive pin 6a fixed below the panorama mask 6 described below is fitted into the fork portion 4a.

The upper and lower panorama masks 5 and 6 are slidably supported by a guide shaft 8 supported by the camera body. The sliding direction is a direction crossing the film running direction. The panorama masks 5 and 6 are provided with rack portions 5b and 6b. Then, they are in mesh with each other via the pinion 9, and when the lower mask 6 moves downward, the mask 5 moves upward via the pinion 9. By the movement, on the panorama mask,
Trimming edges 5c and 6c provided on the lower portions 5 and 6 move across the aperture 10c of the camera body 10 to regulate the size of the photographing screen.

Therefore, when the photographing screen size operation lever 4 is at the normal position, the upper and lower panorama masks 5 and 6 are set.
Are located farthest away from each other, and the trimming edges 5c and 6c provided on the upper and lower masks 5 and 6 are located at positions retracted from the aperture 10c of the camera body 10 (see FIG. 2). However, when the operation lever 4 is rotated from the normal position to the panorama position, the panorama mask 6 is driven via the drive pin 6a and moves upward. At the same time, the upper panorama mask 5 moves downward. In this state, the trimming edges 5c and 6c provided on the upper and lower masks 5 and 6 have moved into the aperture 10c, and the photographing screen is trimmed to a panoramic size (see FIG. 4). ).

To switch the photographing screen to the normal size, manually rotate the screen size operation lever 4 to the normal position, and
The lower edges 5 and 6 are separated from each other, and the trimming edges 5c and 6c are retracted from the aperture 10c. In this state, normal-size shooting can be performed. Then, in order to imprint the imprint data, the LED 2 is made to emit light in synchronization with the running of the film 11 during winding up after one frame shooting. Then, the imprint data light guided by the lens portion 3a of the separator lens 3 forms an image at a predetermined position in the screen through the opening 10a, and imprint data such as characters or numerals is imprinted. .

In order to switch the photographing screen to the panorama size, the screen size operation lever 4 is manually rotated to the panorama position, and the upper and lower panorama masks 5 and 6 are moved inward, and the trimming edge is moved. 5c and 6c are positioned at positions corresponding to the panorama size in the aperture 10c. In this state, panoramic-size shooting is possible. Then, in order to imprint the imprint data, the LED 2 is made to emit light in synchronization with the running of the film 11 after the photographing is similarly completed.

And 84b. The liquid crystal shutters 84a and 84b are set in a transmitting state or a blocking state to block two optical paths emitted from the separator lens 83, or
Will be transmitted. Also, the liquid crystal shutters 84a, 8
An instruction signal for switching between the transmission state and the blocking state of 4b uses an on / off signal of a normal / panorama detection switch 87 operated by the operation projection 85a on the panorama mask 85.

FIG. 24 (A) shows the upper and lower panorama masks 85, 8 when the photographing size is set to the panorama size.
6 shows a state of movement, in which the upper end portion 85a of the panorama mask presses the switch 87 to be in the ON state. In this state, the liquid crystal shutter 84b facing the opening 10b side of the camera body 10 becomes transparent by the output signal, and the liquid crystal shutter 84 facing the opening 10a side.
a is in the shielding state. Then, the light emitted from the panoramic size imprinting lens unit forms an image on the film.

FIG. 24B shows the panorama mask upper and lower sides 85 and 86 when the photographing size is set to the normal size.
The moving state of the panorama mask 85 is shown.
a is separated from the switch 87 and turned off. In this state, the liquid crystal shutter 84a facing the opening 10a side of the camera body 10 becomes transparent by the output signal, and the liquid crystal shutter 84 facing the opening 10b side.
b is in the shielding state. Then, the light emitted from the normal-size imprinting lens unit forms an image on the film.

As described above, in the camera of this embodiment, the optical path of unnecessary data imprinting light outside the set size is blocked by the liquid crystal shutter of the liquid crystal plate 84 mounted on the case 81, and Only the data imprinting light reaches the film, and good imprinting is performed.

FIGS. 25 and 26 are a longitudinal sectional view and a view from the exit surface side in each operating state of the photographic portion of the camera capable of imprinting data according to the eighth embodiment of the present invention. In addition,
FIG. 25 shows a state when the shooting screen is set to the panorama size, and FIG. 26 shows a state when the shooting screen is set to the normal size. In the projection unit of the camera according to the present embodiment, an LED 92 that is a light source for data projection is disposed above, and light emitted from the LED
