Abstract

PURPOSE:To save such waste that an enlarged print and a normal print are simultaneously produced by recording information on desired print size on film, reading said information at the time of printing and automatically setting the magnification of a printing lens at an enlarging or reducing one in response to said information. CONSTITUTION:A negative film 16 is positioned at the normal location of a printing device, and a prescribed printing is carried out as follows: enlarged print information 14a and cancel information 15a are recorded in the central play area of each frame of the film 16. If said information is not found, normal printing is carried out according to a frame 16a. When the enlarged print information 14a is detected, an image is enlarged and printed on a frame 16b following the former frame. When two types of information 14a and 15a are detected, the following frame 16c is printed normally. Thus, a normal, enlarged, or reduced image can be obtained in simultaneous printing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing apparatus capable of automatically changing print size.

[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 you request simultaneous printing, each frame will be printed one by one.

However, the print size is constant and is a so-called service size (for example, L size).

In the case of souvenir photos, there are many people on the screen, so you may want to enlarge only that photo (for example, 2L size). It is then necessary to request a photo lab to make a large enlarged print again.

Also, from the perspective of processing, printing can be done at a very low cost in a simultaneous printing system, where many negative films are linked together and printing is done automatically and continuously. In the case of additional printing, the negative film is usually cut into short pieces of 6 frames, and it is necessary to input information such as the selection of the negative to be printed and the print size into the processing device, which is significantly more time-consuming than simultaneous printing. The number of man-hours has increased, and the cost per print has become high.

[Problems to be Solved by the Invention] In order to solve the above-mentioned problems, it is possible to decide the desired print size at the time of shooting, and then print the desired large enlargement during simultaneous printing. good.

However, with conventional cameras, even if it is known at the time of shooting that a large enlargement is necessary, there is no way to transmit the print size information to the printing device, and therefore, when printing simultaneously, orders are made for large enlargement prints of the necessary frames. I couldn't do it or get it.

[Means for Solving the Problems] The present invention aims to solve the above problems, and provides a printing device that can automatically change the print size based on the print size information recorded on the film surface. It provides:

The printing apparatus of the present invention comprises a reading means for reading desired print size information, and a magnification setting means for automatically setting an enlargement or reduction magnification based on the print size information.

[Example] Next, an example of the present invention will be described. Figure 1 shows
This 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 large extension setting button. 5 is a cancel button for the large stretch setting, and 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 seen from the back cover side, showing the state with the back cover removed.To explain each member, 6 is a cartridge chamber that stores the cartridge, 7 is a film in the optical axis direction. An inner rail 8 regulates the position of the film, and an outer rail 8 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. These members are constructed in the same manner as a conventionally known camera.
Both 4 and 15 are light emitting members such as light emitting diodes,
Reference numeral 14 is for imprinting the large-expansion information onto the film, and 15 is for canceling the large-expansion information.

In the camera configured as described above, the operation when specifying a large enlarged print and photographing will be explained.

When specifying a large enlargement print, first press the large enlargement setting button 4, and then the light emitting member 14 lights up momentarily by a circuit (not shown). Then, as shown in FIG. 3, the portion of the film 16 facing the light emitting member 14 is exposed to light, and large enlarged print information 14a is recorded on the film. After that, if you press the release button 3 to take a picture, or if you accidentally press the large stretch print setting button 4, or if the release button 4 is replaced by the release button,
If you want to cancel it, just press the cancel button 5. In this case, when you press the large stretch setting button 4, the light emitting member 14 lights up as described above, and the large stretch print information 14a is displayed on the film surface. is recorded. however,
Next, by pressing the cancel button 5, the light emitting member 15 lights up momentarily by a circuit not shown. Then, as shown in FIG. 3, the portion of the film 16 facing the light emitting member 15 is exposed and the cancellation information 15a is recorded on the film. After this, press the release button 3 to take a picture. If you want to take a picture at the normal print size without doing a large stretch print, press the release button 3 without pressing the large stretch setting button 4 to take a picture. When photographing is performed with a print size of , when photographing is performed with large enlargement print set, and when photographing is performed with large enlargement print canceled, the film frames are 16a, 16b, and 16c, respectively. FIG. 4 is a diagram schematically showing a printing apparatus for film taken with a camera embodying the present invention. 17 is a negative film and is a film feeding section 1
8 and is wound up by a film winding section 19. A light source section 20 consisting of a lamp, a condenser lens, and a diffuser mixing box is provided in the center.

An information reading section 21, a printing zoom lens 22, and a zoom motor 23 for driving the zoom lens 22 are arranged on the lower surface of the negative film 17. Information reading section 21
includes a negative film 17, a film feeding and winding section 18, 19, a light source section 20, an information reading section 21, a zoom lens 22, and a zoom motor 2, which has a sensor for reading the above-mentioned large enlargement print information and cancellation information.
3 is housed in a housing and constitutes a head 24 of the printing machine. This head portion 24 is rotatably attached to a printing machine main body (not shown). Reference numeral 25 denotes a head rotation motor, which can rotate the head 24 by 90' with respect to its normal position. Below the zoom lens 22 there is a photographic paper delivery section 26 and a photographic paper winding section 27, and the photographic paper 28 is transferred to the delivery section 2.
6 and is wound up by the winding section 27. Further, in front of the printing zoom lens 22, a shutter 29 is provided close to the surface of the photographic paper 28.

Next, to explain the operation of the printing apparatus configured in this way, when a negative film is brought into the printing apparatus, a known frame edge detector (not shown) detects the edges, and the negative film 1
7 is stopped at the normal position.

Next, the sensor of the information reading section 21 reads the presence or absence of the aforementioned enlarged print information 14a and cancellation information 15a recorded on the film. In the case of normal print photography with no information (corresponding to film 916a in Figure 3) & σ large stretch print information 14a and cancellation information 1
When the information reading section 21 detects both information 5a (corresponding to the film frame 16c in FIG. 3), as shown in FIG.
When the information reading unit 21 detects only the large enlarged print information 14a for printing in the normal print size, the control circuit of the printing device (not shown) rotates the zoom motor 23, The zoom lens is driven to double the screen size, and the head rotation motor 25 is rotated to rotate the head 90° relative to normal printing. After that, printing is performed. When printing is performed as described above, printing is performed on the roll of photographic paper as shown in FIG. 5. That is, on the photographic paper 28, compared to the normal print 28a and the print 28c in which the large stretch print setting was canceled, the print 28b with the large stretch print setting is twice the size, and the vertical and horizontal directions are reversed with respect to the prints 28a and 213c. printed in shape. After the fixing process is completed, if you cut the photographic paper at the dotted line in Fig. 5 with a cutter, you can obtain a print according to the settings.In the above embodiment, the information reading section 2 of the printing device
! When detects the large enlarged print information 14a,
Both the zoom lens 22 and the head unit 24 were driven to obtain a double-sized enlarged print, but for example, the head unit was not rotated and only the zoom lens 22 was driven by the zoom motor 23 until the zoom ratio was 4x. If the photographic paper 28 is moved in the front-rear direction of the surface of the paper in FIG. It is also possible to efficiently lay out both on the same photographic paper.

In the above embodiments, the case where an enlarged print is obtained from a normal print has been explained, but it goes without saying that the present invention is also applicable to the case where a reduced print is obtained.

Here, the use of reduced prints is for passport photos,
It is used as a driver's license photo, etc.

[Effects of the Invention] As described above, according to the present invention, if you press the large enlargement setting button on the camera before shooting, it is possible to obtain a large enlarged print of the photographed frame even during simultaneous printing. Therefore, compared to the conventional method of simultaneously printing and then reprinting large enlarged prints, the user not only can reduce the number of trips to the camera store, but also
It also eliminates the waste of producing two large prints (reprints) and regular prints (simultaneous prints) on the same frame.
