DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an index printing apparatus for producing a so-called solid printing positive image used for retrieving a negative image.

[0002]

2. Description of the Related Art In many cases, photographed film is requested to a DP shop for developing and printing the film at the same time.
When reprinting is requested again at a later date, each time the print is viewed, the corresponding image is selected from the negative film, and the screen number to be printed is designated by the screen number.

However, since it is difficult to identify a negative image when there is a similar image, a method has been adopted in which a so-called “solid-state” is used to convert the negative image into a positive image and search for a required screen number.

[0004]

The so-called "solid printing" is one of the simplest means for converting a negative image into a positive image. Even if the negative image can record the photographing conditions simultaneously by, for example, optical or magnetic means, or can additionally record print information, such conditions and information can be displayed on the positive image. It is considered impossible.

As one method for solving such a problem, there is a proposal disclosed in Japanese Patent Application Laid-Open No. Hei 5-11353. In the case of this proposal, first, a positive image is obtained by "solid printing", so that the print size is reduced. In addition to the fact that it is not possible to reduce the size of the negative image, and that the shooting conditions and processing information relating to the negative image are recorded outside the screen of the positive image via the printing device, a printing device is required. However, there is a drawback that it cannot be specifically displayed on the screen.

The present invention has solved and improved the above points,
It is an object of the present invention to provide an index printing apparatus which can obtain a small index print by an extremely simple apparatus and can display conditions and information on photographing and printing directly in a positive image.

[0007]

An object of the present invention is to store trimming information read from a negative film in which a plurality of photographic images and trimming information of each frame are recorded in a control unit, and to store the trimming information and an image of the photographic image. An index printing apparatus, which outputs a signal to a printer, and prints a positive image of the entire negative image on recording paper and a frame line of a trimming range therein, and simultaneously records and displays the image, and a photograph.

Films L1, L2, and L3 are each a lens serving as a projection optical system, and P1, P2, and P3 are used as an index print by reducing and exposing, for example, four positive images of the film F, that is, 24 frames. It is photographic paper as a photosensitive material.

In printing, the film F is intermittently moved in the direction of the arrow for each frame, and correspondingly, each lens or each printing paper is moved in the direction of the arrow, and the print position of each positive image is changed. It is determined. Next, color correction is performed by selecting the filter f, and exposure of a positive image is performed by operating a shutter built in each lens. After the exposure, the photographic paper is developed by a developing unit (not shown) to obtain an index print.

FIG. 1 shows an apparatus for determining the print position of a positive image by moving the lens L1 and the printing paper P1 in the Y and X directions indicated by arrows.

The lens L1 is moved in the Y direction in a plane perpendicular to the direction of transport of the film F including the optical axis of the light source S (indicated by a two-dot chain line), while the photographic paper P

When the first exposure of the film F is completed, the lens L1 is moved one step in the Y direction, and at the same time, the photographic paper P1 is moved in the X direction indicated by the white arrow and returned to the initial position.

Next, by starting the second exposure of the film F, each frame is sequentially exposed by the movement of the photographic paper P1 again in the X direction indicated by the black arrow, and the above operation is repeated. Thus, four frames of the film F can be exposed on one photographic paper.

FIG. 2 shows an apparatus for determining the exposure position of each frame only by moving the photographic paper P2.

The lens L2 is fixed on the optical axis of the light source S (indicated by a two-dot chain line), and the photographic paper P2 is transported in the direction (X direction) of the film F and perpendicular to it in accordance with each frame of the film F and the number thereof. It is moved in two directions (Y direction).

At the time of the first exposure of the film F, the photographic paper P2 is located at the farthest position in the drawing.
.. Are moved by one step each time one frame of the film F is exposed in the X direction indicated by the black arrow, so that the frames 1, 2, 3,...
Exposure is performed as A, 2A, 3A,.

When the first exposure of the film F is completed,
The photographic paper P2 moves in the X direction indicated by the white arrow, returns to the initial position, and is further moved one step in the Y direction.

Next, by starting the second exposure of the film F, each frame is exposed by the movement of the photographic paper P2 again in the X direction indicated by the black arrow, and the above operation is repeated to repeat the index printing. Get.

FIG. 3 shows an apparatus for determining the exposure position of each frame by moving only the lens L3.

The lens L3 is moved in the transport direction (X direction) and the vertical direction (Y direction) of the film F in accordance with each frame of the film F and the number thereof, and the printing paper P3 has its center at the optical axis of the light source S. (Indicated by the dash-double-dot line).

At the time of the first exposure of the film F, the lens L3 is located at the foremost side in the drawing, and

When the first exposure of the film F is completed,
The lens L3 moves in the X direction indicated by the white arrow and returns to the initial position, and then moves one step further in the Y direction to expose the second image on the film F, and repeats this to obtain an index print.

In the above-described embodiment, the index print is formed by using the film cut every six frames. However, a predetermined number of times, for example, six times, can be applied to a so-called long negative film or a film having another number of frames. After the first exposure, the index print may be created by moving the lens or the photographic paper and changing the row of the index print.

In this embodiment, an example is shown in which six frames are exposed in four rows. However, the format can be set arbitrarily, for example, six frames are exposed in six rows.

FIG. 4 shows an embodiment of the index printing apparatus according to the present invention.
