2. Description of the Related Art Printing an image directly from a film is generally carried out by printing on a photosensitive paper, but this method requires a high degree of specialized skill and special equipment. No one can easily print. On the other hand, in recent years, the technology of color copying machines has advanced, and it has become possible to perform color copying of images recorded on paper with high accuracy.

From the above, an image recorded on various films is projected by a projector, and the projected image is photoelectrically read by an image reading device having a photoelectric conversion element such as a CCD sensor in a color copying machine. In recent years, it has been proposed to obtain an electric image signal and perform a color copy by a copying machine based on the electric image signal (see, for example, Japanese Patent Laid-Open No. 3-46646).

In projecting an image recorded on a film by a projector, the film is mounted on the projector using a film carrier to irradiate light, and the transmitted light is diverted by a mirror unit to produce a film. Project the image on the Fresnel lens on the platen of the color copier,
The film image projected on the Fresnel lens is electrically read by a photoelectric conversion element such as a CCD sensor of a color copying machine. Then, according to the read image, the selection of the paper and the print magnification of the image are determined.

As a conventionally proposed image reading apparatus for printing the film projected by the projector as described above, the target is the 35 mm film most commonly used by ordinary people when taking pictures with a camera. ing.

[0006]

By the way, in recent years, panorama-sized photographs have become widespread, and in this case, 35 mm
It uses pseudo panoramic film that records panoramic images on film. As shown in Fig. 5, the pseudo panoramic film has a normal screen size (24 mm x 36 mm) of 35 mm film.
The upper and lower sides of the screen (13 mm x 36 m)
m).

As described above, the size of the projected image of the pseudo panoramic film is extremely different from the projected image size of the normal 35 mm film in terms of the ratio of the vertical and horizontal lengths, so that it is suitable for reading the image of the pseudo panoramic film. The advent of image reading devices is desired. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an image reading apparatus capable of appropriately determining a sheet, a magnification, or a printing position according to a projected panoramic image.

[0008]

Therefore, in the image reading apparatus according to the first invention, means for detecting the inserting direction of the film carrier for inserting the film recording the panoramic image into the projector, and the detecting means. And a sheet determining unit that determines the sheet on which the panoramic image is printed according to the film carrier inserting direction detected in step S4.

In the image reading apparatus according to the second aspect of the invention, the length of the panoramic image projected by the projector in the longitudinal direction and the length of the panoramic image when the panoramic image is printed on a designated sheet. The print magnification determining means is configured to determine the magnification of the print image based on the length of the side of the paper which is parallel to the direction. The image reading apparatus according to the third aspect of the invention is configured to include print position control means for controlling the print position of the panoramic image on the paper.

Further, the print position control means calculates a number of panoramic images printable on the paper based on the size of the selected paper, and a plurality of images calculated by the calculation means. A configuration is also provided that includes a designating unit that designates the print position of each image on the paper.

[0011]

According to the structure of the first invention, for example, A4
If the size of paper is the default and the insertion direction is parallel to the longitudinal direction of the panoramic image, A4 (horizontal) paper is selected and the insertion direction is parallel to the lateral direction of the panoramic image. A4R for mold insertion
(Portrait) paper is selected, and paper is selected according to the orientation of the panoramic image.

According to the structure of the second aspect of the invention, the panoramic image is extremely long in the horizontal direction with respect to the length in the vertical direction as compared with the print paper, so that the panoramic image is surely prevented from protruding from the print paper. The panoramic image can be printed so that it fits on the paper. Further, according to the configuration of the third invention, it is possible to print at a desired position on the print paper.

Further, when a plurality of panoramic images can be printed on the printing paper, the printing can be performed without forming a blank on the paper, and the waste of the printing paper can be prevented.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an image reading apparatus for a pseudo panoramic film according to the present invention. In FIG. 1, the film insertion detection sensors 1 and 2 are provided in the projector 3, and the film insertion detection sensor 1 is arranged in the longitudinal direction and the main scanning direction of the pseudo panoramic film 21 as shown in FIG. The film insertion detection sensor 2 detects the insertion of the film carrier 22 in the direction in which
As shown in (B), it is detected that the film carrier 22 is inserted in the direction in which the lateral direction of the pseudo panoramic film 21 and the main scanning direction coincide with each other.

The paper size designation operation unit 4 can switch between an automatic mode and a manual mode. In the automatic mode, A4 (horizontally long) paper and A4R (longitudinal) paper are used in the present embodiment, as will be described later. It is selected according to the inserting direction of the film carrier 22. Further, in the manual mode, an arbitrary paper size is selected. In this embodiment, the A4 size is the default, but other paper sizes may be used.

Similarly, the magnification designation operation section 5 can be switched between an auto mode and a manual mode. In the auto mode, as will be described later, it is calculated and set by a predetermined calculation formula according to the inserting direction of the film carrier 22. In the manual mode, any magnification can be input. The print position designation operation unit 6 can select a centering mode for printing in the center of the paper and a frame designation mode for performing a plurality of prints on the paper.

The film / paper size storage unit 7 stores in advance the sizes of various readable films and the sizes of various papers to be used. The paper size holding unit 8, the magnification holding unit 9, and the print position holding unit 10 are configured by RAM, and designated by the paper size designated in the auto mode or the manual mode, the print magnification, the centering designation, and the frame designation. The respective print positions are temporarily stored and held.

The CPU 11 outputs each of the above-mentioned film insertion detection sensors 1 and 2, the paper size designation operation unit 4, the magnification designation operation unit 5, the print position designation operation unit 6 and the storage of the film / paper size storage unit 8. Based on the data, the paper size, the print magnification, and the print position are respectively determined and stored in the paper size holding unit 8, the magnification holding unit 9, and the print position holding unit 10, and the frame specifying mode is set in the print position specifying operation unit 6. The number of images printed on the paper and the position of the frame within the paper when selected are displayed on the print frame number display device 12
To display. Here, the CPU 11 is the film carrier
A sheet determining unit that determines the sheet according to the inserting direction of 22,
A print magnification determining means, a print position control means, a calculating means for calculating the number of panoramic images that can be printed on the paper based on a specified paper size, and a paper for each image when the calculated number of images is plural. It has respective functions as a designating unit for designating a print position in.

Next, the operation of the image reading apparatus of this embodiment will be described. First, a case where both the paper size and the magnification are designated as auto will be described. For example, when the film carrier 22 is laterally inserted as shown in FIG. 2A, the film insertion detection sensor 1 detects this and turns on.
The signal is input to the CPU 11. Then, the CPU 11 selects the sheet size A4, and the selected sheet size A
4 is temporarily stored and held in the paper size holding unit 8.

Further, the CPU 11 reads out the lateral length (longitudinal direction of the film) of the inserted pseudo panoramic film and the lateral length of the selected A4 paper from the film / paper size storage unit 7, respectively, and ) The magnification Z is calculated based on the equation. Z = (horizontal length of paper) / (horizontal length of film projection image) (1) The calculation result is temporarily stored and held in the magnification holding unit 9.

When the paper size and the magnification are auto, the number of images to be put on the paper is one, and the print position designating operation unit 6 designates the centering mode to print the image at the center of the paper. This centering operation is
As shown in FIG. 3, the center Cf of the film image A is the paper B.
The CPU 11 calculates the print position so that it overlaps the center Cp of the print position, and the print position holding unit 10 temporarily stores and holds the print position.

Next, when the film carrier 22 is vertically inserted as shown in FIG. 2B, the film insertion detection sensor 2 detects this and the ON signal is input to the CPU 11.
Then, the CPU 11 selects A4R as the paper size,
The selected paper size A4R is the paper size holding unit 8
Will be temporarily stored in. In addition, the CPU 11 determines the length of the inserted pseudo panoramic film in the vertical direction (longitudinal direction of the film) and the length of the selected A4R paper in the vertical direction.
Read each from the paper size storage unit 7, and use the following (2)
The magnification Z is calculated based on the equation.

Z = (vertical length of paper) / (vertical length of film projection image) (2) The calculation result is temporarily stored and held in the magnification holding unit 9. Then, the print position designation operation unit 6 designates the centering mode, determines the print position of the image in the same manner as described above, and temporarily stores and holds it in the print position holding unit 10.

In this way, the projection image of the pseudo panoramic film is printed on the paper based on the paper size, the magnification and the print position which are respectively determined. When the paper size and the magnification are manually specified, the paper and the magnification as specified by the paper size designation operation unit 4 and the magnification designation operation unit 5 are irrespective of the detection outputs of the film insertion detection sensors 1 and 2. It is selected and stored in each of the holding units 8 and 9. In addition, when a magnification is designated by a manual operation, and an image runs off the paper at the designated magnification, a warning is issued in advance.

Further, for example, the film carrier 22 is shown in FIG.
When the paper size is specified as A4R by inserting it horizontally as shown in (A), the panorama image is extremely long in the lateral direction. Multiple panoramic images can be printed. In this case, when the frame designation mode is selected by the print position designating operation unit 6, the CPU 11 calculates how many panoramic images can be printed on the sheet based on the designated sheet size, and, for example, when three frames are entered. , The calculation result is printed frame position display device
It is displayed in 12 as shown in FIG. Then, the currently projected panoramic image is displayed on the print frame position display device 12
When the print position designation operation unit 6 designates which position among the 1 to 3 frame positions displayed on the print position, the designated position is temporarily stored and held in the print position holding unit 10. For example, if 3 is designated, the third frame at the bottom of the paper B in FIG. 4 is printed.

By doing so, a plurality of panoramic images can be printed on one sheet, the sheets can be saved, and the waste of sheets can be eliminated. Although the present embodiment has been described using the projection type image reading apparatus, it goes without saying that the same effect can be obtained by using the scanner type image reading apparatus.

[0027]

As described above, according to the present invention, it is possible to provide an image reading apparatus suitable for reading an image of a panoramic film which is extremely long as compared with a standard size film. Further, by printing a plurality of images on one sheet, it is possible to effectively print the panoramic image on the sheet without making unnecessary blanks on the sheet, and it is possible to reduce the waste of the sheet.
