Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing apparatus that can automatically change the aspect ratio of prints.

[Prior Art] In recent years, so-called simultaneous printing systems have become widespread, in which when sending film that has been photographed to a processing laboratory, if simultaneous printing is requested, each frame will be printed one by one. However, the print size, print aspect ratio, etc. are constant, and are what is called a service size.

For example, in the case of landscape photos (photos of mountain ranges, horizon photos, etc.), you may want to print them horizontally (so-called cinescope size). It requires the trouble of requesting the printing to a photo lab.

In addition, from the perspective of printing processing, a simultaneous printing system connects a large number of negative films and prints automatically and continuously, making it possible to print at a very low cost. In this case, the negative film is usually cut into short pieces of 6 frames,
It is necessary to input the selection of the negative to be printed, the print size, etc. to the processing device, which significantly increases the number of man-hours compared to simultaneous printing, and the cost per print is high. In particular, in the case of landscape prints like those mentioned above, because the photographic paper is of a special size, it cannot be printed using normal printing processes and is currently printed by hand, making the prints increasingly expensive. Put it away.

[Problems 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 photographing, and to print at the desired aspect ratio during simultaneous 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 it is not possible to order landscape prints of the necessary frames when simultaneously printing. , I couldn't even get it.

[Means for solving the problem] The present invention aims to solve the above problems,
The present invention provides a printing device that can create prints with automatically changed aspect ratios based on print aspect ratio information recorded on a film surface.

The printing apparatus of the present invention comprises a reading means for reading aspect ratio information of a desired print, and a magnification setting means for automatically setting a printing magnification based on the aspect ratio information.

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

FIG. 1 is an external view of a camera embodying the present invention, and its main components are: 1 a camera body, 2 a photographic lens, 3 a release button, and 4 a landscape print setting lever. Reference numeral 5 denotes a cancel button for landscape print settings, which is configured to be pressed with a fingernail to prevent it from being pressed by mistake.

FIG. 2 is a front view of the camera viewed 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 into which a back cover (not shown) is fitted.

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 interlocking relationship of the horizontal print setting lever 4, the cancel button 5, and the finder 11.
is the aforementioned camera body, shown here in partial section. 4 is the above-mentioned landscape setting lever, and the fixed bin 15
This allows it to slide left and right. Reference numeral 16 denotes a finder field switching member, which is provided with a finder field frame 16a for normal printing and a finder field frame 16b for horizontally long prints. The finder visual field switching member 16 is slidable in the left-right direction by a fixed pin 17, and is always biased leftward by a spring 18. 19
is 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. The rotation is energized.

The other end 19b of the tensioning lever 19 faces the tip of the cancel button 5 described above, and also faces a lever 22 that is interlocked with a film winding mechanism (or release mechanism) not shown. Reference numeral 23 denotes a detection switch for detecting landscape print settings, and is configured to be turned off during normal printing and turned on during landscape printing by the protrusion 16d of the switching member 16.

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 tip 4a of the setting lever 4 pushes the finder field of view switching member 16,
The switching member 16 slides to the right against the spring 18. When sliding the full stroke, the tension lever 19 releases the spring 21.
The one end 19a of the tensioning lever 19 is rotated clockwise by
and the notch 16c of the switching member 16 engage with each other, resulting in the state shown in FIG. 4. In this state, the field frame 16b for landscape printing 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 is on, the light emitting member 14 lights up momentarily by a circuit (not shown). Then, as shown in FIG.
The portion facing the light-emitting member 14 is exposed, and horizontal print information 14a is recorded on the film. During the film winding operation after the shutter release, the lever 22 is rotated clockwise by a mechanism (not shown) and pushes one end 19b of the tension lever 19. Then, the tensioning lever 19 rotates counterclockwise against the spring 21, and is disengaged from the switching member 16. Then, the switching member 16 slides in the pressure direction by the spring 18 and returns to the state shown in FIG. 3, that is, the state in which the finder 11 and the viewfinder field frame 16a 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 change your mind after operating the landscape print setting lever 4 and want to cancel it, you can press the cancel button 5. When the cancel button 5 is pressed in the state shown in FIG. 4, its tip presses one end 19b of the tension lever 19.
The tension lever 19 rotates counterclockwise, and the tension lever 19
The engagement between the distal end 19a and the notch 16c of the switching member 16 is disengaged, the state returns to the state shown in FIG. 3, and the landscape print setting is released. In order to take a photograph in the normal print size, the shutter release can be performed without operating the setting lever 4 in the state shown in FIG. 4.

In this case, since the detection switch 23 is off, the light emitting member 1
No. 4 does not light up, and no landscape print information is recorded on the film. As described above, when photographing is performed with normal print and when photographing is performed with landscape print set, the film frames are 24a and 24b, respectively. FIG. 6 is a diagram schematically showing an apparatus for printing film taken with a camera embodying the present invention. 31 is a negative film sent out from the film delivery section 32 and taken to the film winding section 3.
It is wound up in 3. In the center is a light source section 34 consisting of a lamp, condenser lens, diffuser, and mixing box.
is provided. On the bottom surface of the negative film 31, there is an information reading section 35, a printing zoom lens 36, and a zoom lens 36.
A focusing motor 37 is arranged to perform focusing. The information reading section has a sensor for reading the above-mentioned landscape print information. The negative film 31, film feeding and winding sections 32, 33, light source section 34, information reading section 35, zoom lens 36, and focusing motor 37 are housed in a housing, and the head section 3 of the printing device
8. 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. zoom lens 3
6, there are a photographic paper delivery section 40 and a photographic paper winding section 41, and photographic paper 42 is sent out from the delivery section 40 and wound up on the winding section 41. Further, in front of the printing zoom lens 36, a shutter 43 is provided close to the photographic paper surface.

Next, the operation of the printing apparatus configured as described above will be explained. When the negative film comes to the printing position, a known frame edge detector (not shown) detects the edge and stops the negative film 31 at a normal position. Next, the information reading section 35
The sensor reads the presence or absence of the aforementioned 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 section 35 detects the horizontal print information 14a, the control circuit of the printing device (not shown) moves the head section 38 upwards by the head section sliding motor 39 so that the screen size is enlarged compared to the normal print. move in the direction.

Further, the focusing motor 37 performs focusing at the moved position. Further, the opening shape of the shutter 43 is changed to an opening shape for horizontally long printing, and trimming for horizontally long printing is performed. The size of the trimming is set to the size indicated by the two-dot chain line in FIG. After that, it is baked.

When printing is performed as described above, printing is performed on the roll of photographic paper as shown in FIG.

That is, on the photographic paper 42, a print 42b with landscape print settings is printed in contrast to the normal print 42a. After the fixing process is completed, by cutting the photographic paper 42 along the broken line in FIG. 7 with a cutter, a print as set can be obtained.

The enlarged size of the horizontally long print is such that the length of the short side of the horizontally long print almost matches the length of the short side of the normal 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, the print head was simply moved upward, but if the print head was moved upward and rotated 90 degrees for printing, As shown in FIG. 8, a roll of photographic paper 142
Above, the horizontal print 142b is compared to the normal print 142a.
Can be printed with a 90° offset. 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 almost matches 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.

Moreover, in order to be able to select 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 to determine the aspect ratio for each piece of information. In the embodiments described above, the switching of the viewfinder field frame was explained as being performed by a mechanical structure, but it goes without saying that the present invention can also be constructed by using an element such as a liquid crystal or the like.

[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 obtaining landscape prints using reprints after simultaneous printing, the user can not only reduce the number of trips to the camera store, but also make landscape prints (reprints) of the same frame. It also eliminates the waste of creating two normal prints (simultaneous prints).

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.
