Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a color printer capable of printing a plurality of screens on one sheet of photographic paper.

[Conventional technology]

Using the power of rolled photographic paper, the method of printing different images on a rolled I-sheet as photographs of different sizes has been used for souvenir photographs of tourist spots and the like.

In that case, the group photo of people is generally 7' in large size.
It is a set of IJ images, landscapes, etc. in oval size, and has been compiled into a single commemorative photo.

Methods for creating such photographs include setting multiple lenses on the printer and printing each screen at the same time, or moving the same lens and sequentially printing at different positions on the photographic paper. Alternatively, for small-sized photographs, there is a method of contact printing 3 using a separate light source, without using a printer.

[Problem that the invention seeks to solve]

However, with the methods described above, such as using multiple lenses or simply moving them two-dimensionally, there are restrictions on the layout and magnification, which limits the print position and size, making it impossible to create prints in a free format. .

In addition, the method of contact printing using a separate light source has the disadvantage that light control and color balance adjustment must be performed separately from the printer, requiring much labor and time for setup and work.

The present invention solves and improves this point, and as a result, it is possible to efficiently print multiple images on one sheet of photographic paper using a free format by utilizing the functions of conventionally used color printers. The aim is to provide a color printer that can.

[Means for solving problems]

The above objects are (a) a means for moving the projection lens position in a direction other than the photographic paper feeding direction, (b) a means for moving the projection lens position in a direction substantially perpendicular to the photographic paper surface, and (c) a photographic paper surface or film surface. means for moving the projection lens in the optical axis direction;
(d) It has a means for minutely feeding the photographic paper in the feeding direction, and inputs the setting conditions for printing in (a), (b), (c), and (d) above into a control section, and This is achieved by a color printer characterized in that printing is performed according to set conditions.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 to 6.

(As shown in Fig. 1, a fixed negative film N is illuminated from below by a light source 2, and the image is stored in a lens deck 3, which is placed above through a projection lens 3a. The image is projected onto the sheet surface 4b of photographic paper 4a in the paper deck 4, and the image is printed by opening and closing the shutter 3 in the lens deck 3.

Additionally, this color printer is equipped with an automatic focus adjustment function for the projected image to be printed, and when the projection magnification is selected prior to printing, the pulse motor Ml ,M
The lens deck 3 and the paper deck 4 are respectively moved up and down to set a predetermined magnification and imaging position.

Further, in the present invention, the projection lens 3a and the shutter 3b are housed in a lens unit 5, and the lens unit 5 is configured to be movable relative to the lens deck 3 in the width direction of the photographic paper 4a, that is, in the direction of the arrow AA force. .

Figure 2 shows an example of the mechanism, in which the lens unit,
5′? r: The attached support plate 6 is supported so as to be able to slide only in the direction of arrow AA force with respect to a pair of guide rails 7 fixed to the lens deck 3, and is attached to a pulley 9a and a floating pulley 91' that are integrated with the pulse motor M3 shaft. The support plate 6 is connected to the wound timing belt 10.
It is designed to be transported together with the

Also, the guide rail 7 uses a photoelectric device to detect the lens position? A lens position detection plate (81) fixed on the support plate 6 is read to detect the movement position in the AA force direction.

Therefore, when the pulse motor M3 is energized and the timing held 10 is driven, the lens unit 5 moves in the direction of the arrow AA force, and the optical axis of the projection lens 3a moves in the width direction of the photographic paper 4a. is detected by the lens position detector 8a that reads the mark on the lens position detection plate 8b, and the signal is sent to the control section, and when the preset movement amount is reached, the pulse motor M3 is de-energized and the projection lens is moved. The movement of 3a is stopped.

Next, the printing operation by the color printer of the present invention will be explained.

FIG. 3 shows an example in which two types of images P1 and P3 with a magnification of m1 and an image P2 with a magnification of m2 are successively projected and printed on one sheet of photographic paper 4a according to the illustrated layout. The image is the center line XX in the width direction of the photographic paper 4a
and the intersection CI with the center iYY of each sheet perpendicular to it
The photographic paper 4a is placed at a distance specified in the figure from (c2), and is sequentially projected and printed onto the print sheet by intermittently conveying the photographic paper 4a in the direction of arrow B using a pulse motor or the like as a power source. do.

This is a perspective view showing each part of the photographic paper 4a. First, the center C3 of the negative film N1 and the center CI (c2
), the projection lens 3a occupies a position L2 in the optical axis direction in order to adjust the size of the image P1 to the magnification m1 by the above-mentioned automatic focus adjustment function, and also illuminates the photographic paper 4a in the same way. The image P1 is moved to the position 4a2 in the axial direction to satisfy the condition 4a2, and then the image P1 is moved by a distance Yb from the center line XX in the width direction of the photographic paper 4a as shown in FIG. 3 using the lens position detection function described above. The projection lens 3a is moved in parallel by an amount corresponding to , and set to the position Ll.

In this state, the photographic paper 4a is exposed and printed by opening and closing the shutter 3b.

Next, a negative film N2 corresponding to the image P2 is sent and placed at the position of the negative film N1, and the photographic paper 4
When a is fed and moved by a distance I'AI in the direction of arrow B, and the projection lens 3a returns to the position L2, the automatic focus adjustment function operates again and the size of the image P2 is adjusted to the magnification m2. The photographic paper 4a is moved to the position 4al in the optical axis direction in order to adjust the position L3, and then the photographic paper 4a is moved to the position 4al in the optical axis direction, and then the lens position detection function described above is used again as shown in FIG. The projection lens 3a is moved in parallel by an amount equivalent to moving the image P2 by a distance Ya from the center line XX in the width direction of the photographic paper 4a, and set to the position L4.

In this state, exposure and printing are performed on the photographic paper 4a by opening and closing the shutter 3b.

By repeating the same action, the image P3 of the negative film N3 is
is projected and printed at the position shown in FIG. 3, but when moving to the next sheet after exposure and printing of one sheet, the photographic paper 4a is moved a distance PA3 in the direction of arrow B as shown in FIG. It will be transported, moved, and carried out.

When carrying out such a print project, the data necessary to control the movement of each part of the printer can be summarized as shown in the table of FIG. 5, and the magnification m'l,
