CONSTITUTION:When a lengthwise print, for instance, is designated and photographed, a lengthwise print setting lever 4 is shifted to the right, and a finder field switching member 16 is pushed through a leading edge 4a and slid to the right against a spring 18. When the member is slid by a whole stroke, a fixing lever 19 is turned clockwise by a spring 21 to fit the one end 19a of the lever 19 into the notched part 16c of the member 16. In such a way, a visual field frame for a lengthwise print 16b is fitted to the position of a finder 11, which is switched for a lengthwise print, and simultaneously a detecting switch 23 is turned on. If a release button 3 is pushed in that state, a light emitting member (not shown in figure) instantaneously lights up to expose a part facing film, and a desired lengthwise video can thereby be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera that records aspect ratio information of prints.

[Prior Art] In recent years, a so-called simultaneous printing system has become widely used, which prints one frame for each frame if you request simultaneous printing when sending photographed film to a processing laboratory. However, the print size, print aspect ratio, etc. are fixed and are called the so-called service size. For example, in the case of landscape photos (photos of mountain ranges, photos of the horizon, etc.), you may want to print them horizontally (so-called cinescope size).To do this, look at the photos that were printed at the same time and then print them horizontally. This requires the hassle of requesting the processing from a photofinishing laboratory.

Also, from the perspective of printing processing, in a simultaneous printing system, many negative films are connected and printing is performed automatically and in a connected manner, so printing can be done at a very low cost, but in the case of reprints. In order to do this, it is necessary to input information such as the negative film, which is usually cut short into 6-frame units, the selection of the negative to be printed, and the print size, into the processing device, which significantly increases the number of man-hours compared to simultaneous printing. The cost per piece is high. In particular, in the case of horizontally long prints as described above, because the size of the photographic paper is special, it cannot be printed using normal printing processes, and the current situation is to print by hand, making the prints increasingly expensive.

[Problem to be solved by the invention] In order to solve the above-mentioned problems, it is necessary to determine the desired aspect ratio of the print at the time of shooting, and to print at the desired aspect ratio when simultaneously printing. do it.

However, with conventional cameras, even if it is known at the time of shooting that a landscape print is required, there is no way to record the aspect ratio information on the film surface, so when printing simultaneously, it is necessary to order landscape prints of the necessary frames. I couldn't find anything or get anything.

[Means for Solving the Problems] The present invention aims to solve the above problems, and allows the photographer to record print information of a desired aspect ratio on the film surface at the time of shooting. The aim is to provide a camera that can do this.

The camera of the present invention includes means for setting aspect ratio information of a desired print, and recording means for recording the set aspect ratio information on the film surface.

[Example] Next, embodiments of the invention will be described.

Fig. 1 is an external view of a camera embodying the present invention, and the main components are: l the camera body, 2 the photographing lens, and 3 the release button.

4 is a landscape print setting lever. 5 is a cancel button for landscape print settings, and is configured to be pressed with a fingernail to prevent it from being pressed by mistake. Figure 2 is a front view of the camera as seen from the back cover side, with the back cover removed. To explain each member, 6 is a cartridge chamber for storing a cartridge, 7 is an inner rail that regulates the position of the film in the optical axis direction, and 8 is an outer rail that regulates the position of the film in the vertical direction. 9 is a spool chamber for winding the film, and 10 is a spool for winding the film. 11 is a finder, and 12 is a back cover groove that fits into a back cover (not shown). Further, 13 is an aperture.

Reference numeral 14 denotes a light emitting member such as a light emitting diode, which is used to imprint landscape print information onto the film.

FIG. 3 is a diagram showing the internal structure of the camera, and shows the above-mentioned landscape print setting lever 4. Indicating the interlocking relationship between the cancel button 5 and the finder 11, l is the camera body, which is shown here in a partial cross section. Reference numeral 4 designates the above-mentioned horizontally long print setting lever, which can be slid in the left and right direction by means of a fixing pin 15. 16 is a finder field of view switching member; 1 finder field of view frame 16a for normal printing;
A viewfinder field frame 16b for horizontal printing is also provided. The finder field of view switching member 16 is slidable in the left and right direction by means of a fixing pin 17, and also has a wing 18.
is constantly biased to the left. Reference numeral 19 denotes a tensioning lever, which is rotatably supported by a fixed shaft 20, one end 19a of which can be engaged with a notch 16c of the finder field switching member 16, and which is always rotated clockwise by a spring 21. Rotationally biased. The other end 19b of the tension lever 19
is opposite to the tip of the cancel button 5 mentioned above, and
It also faces a lever 22 that is interlocked with a film winding mechanism (or release mechanism) not shown. 23 is a detection switch that detects the landscape print setting, and the switching member 16
The protruding portion 16d is configured to be turned off during normal printing and turned on during landscape printing.

In the camera configured as described above, the operation when specifying landscape print and photographing will be described below. When specifying landscape print, first operate the landscape print setting lever 4 to the right in FIG. 3. Then, the setting lever 4
The tip 4a pushes the finder field switching member 16,
The switching member 16 slides to the right against the spring 18.

When sliding the full stroke, the tension lever 19 is rotated clockwise by the spring 21, and one end 19a of the tension lever 19 engages with the notch 16c of the switching member 16, resulting in the state shown in FIG. 4. . In this state, the horizontal printing field frame 16b of the switching member 16 matches the position of the finder 11,
The finder is set for landscape printing and the detection switch 23 is turned on. When the release button 3 is pressed in this state, the shutter is released by known means (not shown). When the shutter release is performed while the detection switch 23 is on, the light emitting member 14 lights up momentarily by a circuit (not shown).

Then, as shown in FIG. 5, the light emitting member 1 of the film 24
4 is exposed, and the horizontal print information 14a
recorded on film.

Lever 2 is activated by film winding operation after shutter release.
2 rotates clockwise by a mechanism (not shown) and pushes one end 19b of the tensioning lever 19.

Then, the tensioning lever 19 rotates counterclockwise against the spring 21, and is brought into and out of engagement with the switching member 16. Then, the switching member 16 is slid leftward by the spring 18 and returns to the state shown in FIG. 3, that is, the finder 11 and the viewfinder field frame 16 for normal printing are aligned and the detection switch 23 is turned off. If you accidentally move the landscape print setting lever 4, or if you want to cancel it after operating the landscape print setting lever 4, you can press the cancel button 5.
When you press the cancel button 5 in the state shown in the figure, the tip of the cancel button 5 presses one end 19b of the tension lever 19, so the tension lever 19
Then, the tip 19a of the tensioning lever 19 and the notch 16c of the switching member 16 engage and disengage, returning to the state shown in FIG. 3, and the landscape print setting is released.

To take a picture in the normal print size, the shutter release can be performed without operating the setting lever 4 in the state shown in FIG. In this case, since the detection switch 23 is off, the light-emitting member 14 does not light up, so no landscape print information is recorded on the film. From the above, when shooting with normal print and when shooting with landscape print set, the film frames are 24a and 2, respectively.
It becomes 4b.

FIG. 6 is a diagram schematically showing a printing device for film taken with a camera embodying the present invention.

A negative film 31 is sent out from a film delivery section 32 and wound up by a film winding section 33. A light source section 34 consisting of a lamp, a condenser lens, a diffusion plate, and a mixing box is provided in the center. negative film 3
1 has an information reading section 35 and a zoom lens 3 for printing.
6. A focusing motor 37 for focusing the zoom lens 36 is provided. The information reading section 35 has a sensor for reading the above-mentioned landscape print information. Negative film 31, film feeding and winding section 32,
33, a light source section 34, an information reading section 35, a zoom lens 36, and a focusing motor 37 are housed in a housing and constitute a head section 38 of the printing device. This head portion 38 is attached to the main body of the printing apparatus (not shown) so as to be slidable in the vertical direction. Reference numeral 39 denotes a head section sliding motor, which can slide the head section 38 in the vertical direction with respect to the normal position. Below the zoom lens 36, there is a photographic paper feeding section 40 and a photographic paper winding section 41.

Photographic paper 42 is sent out from the delivery section 40 and wound up by the winding section 41. Further, in front of the printing zoom lens 36, a shutter 43 is provided near the surface of the photographic paper.

Next, to explain the operation of the printing apparatus configured in this way, when the negative film 31 comes to the printing position, a known frame edge detector (not shown) detects the edge and stops the negative film 31 at the normal position. . Next, the sensor of the information reading section 35 reads the presence or absence of the above-mentioned landscape print information 14a recorded on the film. In the case of photographing a normal print without any information (corresponding to 24a in FIG. 5), printing is performed in the normal print size as shown in FIG. 6.

When the information reading unit 35 detects the horizontal print information 14a, the control circuit of the printing device (not shown) rotates the zoom motor 23, and the head sliding motor 39 rotates the zoom motor 23 so that the screen size is enlarged compared to the normal print. The head portion 38 is moved upward. Furthermore, focusing is performed at the position moved by the focusing motor 37.

In addition, the opening shape of the shutter 43 is changed to an opening shape for horizontally long prints, and trimming for horizontally long prints is performed.
The size of the trimming is set to the size indicated by the two-dot chain line in FIG. After that, baking is performed. When printing is performed as described above, printing is performed on the roll of photographic paper as shown in FIG. In other words, there are 42 normal prints on the photographic paper 42.
Print 42b with landscape print settings for a
or printed. After the fixing process is completed, use the cutter to remove the seventh
By cutting the photographic paper 42 along the broken line in the figure, it is possible to obtain a print according to the settings. The enlarged size of landscape print is
The length of the short side of the landscape print should be approximately the same as the length of the short side of the regular print. Then, as can be seen from FIG. 7, normal prints and landscape prints can be efficiently laid out on the same roll of photographic paper.

In the above-mentioned embodiment, in the case of landscape printing, it was possible to cope with printing by simply moving the head section upward, or by moving the head section upward and rotating the head section 90'' to perform printing. As shown in FIG. 8, a horizontal print 142b can be printed on a roll of photographic paper 142 with a horizontal print 142b shifted by 90'' from a normal print 142a. in this case,
The enlarged size of the horizontally long print is such that the length of the short side of the horizontally long print is approximately equal to the length of the long side of the normal print. Then, as can be seen from FIG. 8, normal prints and landscape prints can be efficiently laid out on the same roll of photographic paper.

Note that the aspect ratio of the horizontally long print according to the present invention may be determined uniquely, for example. In addition, in order to be able to select from two or more types of aspect ratios, it is sufficient to increase the number of detection switches and the number of light emitting members and determine the aspect ratio for each piece of information. Although it has been explained that the finder field frame is switched by a mechanical structure, it goes without saying that the present invention can also be implemented by using an element such as a liquid crystal.

[Effects of the Invention] As described above, according to the present invention, by pressing the landscape print setting button on the camera at the time of photographing and then photographing, it is possible to obtain a landscape print of the photographed frame even during simultaneous printing. Therefore, compared to the conventional method of simultaneously printing and then reprinting landscape prints, this not only reduces the number of trips the user makes to the camera store, but also
It also eliminates the waste of creating two horizontal prints (reprints) and regular prints (simultaneous prints) on the same frame.

Furthermore, according to the present invention, the same roll of photographic paper can be used for normal size prints and landscape size prints.
There is no need to treat landscape size as a special size, and landscape prints can be obtained at a very low cost.
