DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to an index print sintered TsukeSo location for printing, by exposure, the index print is used as the heading of the frame image of the film on the photosensitive material.

[0002]

2. Description of the Related Art A so-called index print is generally prepared in which a photosensitive material is printed and exposed so that an image recorded on a film can be seen at a glance.

[0003] By giving the index print to the customer, the customer can find the index print immediately by looking at the index print without having to compare and find which frame image of the print corresponds to which frame image, which is very convenient.

In a conventional photographic printing apparatus, a photosensitive material is fed from a magazine to a photographic printing apparatus, the photosensitive material is positioned with a paper mask, and the developed film set on a negative mask is irradiated with a light source of a halogen lamp. Is exposed to a photosensitive material, and the photosensitive material is subjected to a developing process,
After passing through the drying unit, each frame is cut and taken out.

A mechanism for creating an index print with such a photographic printing apparatus sets a film on a special mask (so-called solid printing mask), attaches the special mask to the photographic printing apparatus, and adheres the film so that the film image adheres to the photosensitive material. Exposure (so-called solid printing) is performed to create an index print.

[0006]

However, in the above-mentioned conventional photographic printing apparatus, each time an index print is created, a developed film is set on a dedicated mask each time.
The special mask must be attached to the photo printing device, which makes the work complicated and inefficient, and because the close exposure is used, each frame image of the film is printed with the original size, so index prints of the same size as normal prints And there are various problems such as poor appearance because the edge of the film is also exposed by printing.

The present invention has been made in consideration of the problems of the conventional method of making an index print by a photographic printing apparatus, and prints and exposes a photosensitive material held on a paper mask at a position where a film image held on a negative mask is irradiated. The index print is automatically exposed by moving the lens unit provided in close proximity to the photosensitive material, adjusting the size and position of the paper mask, and printing each frame image of the film. An object of the present invention is to provide an index print printing method and apparatus for efficiently producing an index print with good quality.

[0008]

As a means for solving the above-mentioned problems, the present invention is to print an image of a film held by a negative mask on a photosensitive material held by a paper mask by irradiating the film with light from one light source.

A control unit for changing is controlled to the corresponding magnification provided to move the lens unit for each image of the film each frame according to one light source, an image recorded on one film one or a plurality of the printed circuit In addition, an index print printing apparatus is constructed so as to be freely printed and exposed as an index print.

[0009]

[0010] In addition, as a dual-purpose device capable of obtaining an index print and a normal print, an image of a film held on a negative mask is irradiated onto a film by irradiating light from one light source onto the film to a photosensitive material held on a paper mask. A printing exposure means for printing normally by printing with a lens and a shutter, and a set of lens units provided movably with respect to the paper mask at the same exposure position and in contact with the photosensitive material; Is provided in the mask frame, the paper mask is capable of adjusting the mask position freely, and the mask window plate combined in the vertical and horizontal directions is freely movable in parallel with the film surface by the drive unit so that the mask area can be adjusted freely. The drive unit moves freely along the rod in parallel to the film surface. A control unit that changes the optical magnification freely and controls the exposure magnification to a magnification corresponding to the number of film frames read by an optical reader is provided. During normal printing, the lens unit is moved out of the print frame, and index printing is performed. Sometimes, the lens of the printing exposure means for normal printing is removed outside the optical path, and the image recorded on one film is
An index print printing apparatus may be configured so that printing exposure can be freely performed as an index print on one or a plurality of prints.

In this printing apparatus, the paper mask and the lens unit are provided in a mask frame, and the mask area is freely adjustable by moving a mask window plate combined in a vertical and horizontal direction in parallel with the film surface by a driving unit.

The normal printing is performed by the normal printing exposure unit 10.
N, the number of film frames is first read by an optical reader 31 as shown in FIG.
When the number of film frames is calculated at 0 and an instruction to perform normal printing is received, the dimming filter 12 is controlled, the shutter time is obtained by calculation, the shutter is opened, and exposure for normal printing is performed.

At this time, the lens unit 17 is retracted outside the exposure surface of the paper mask 16. After normal printing is performed for all frames of one film, the process proceeds to index printing.

At the time of index printing, the photosensitive material PC first stops the frame portion on which the index printing is to be performed on the paper mask 16 and feeds the film F backward and forwards the top of each frame of the film to the negative mask 13. Again, the image is sequentially sent for each frame in the same manner as in normal printing.

Further, the lens 14 for normal printing is retracted out of the optical path, and the lens unit 17 is driven by the driving unit 20 for the ball screw at the section position of the index print corresponding to the number of frames read by the optical reader 31. Motor 24a,

The 6X and 16Y are moved by driving the drive motor 22 for the timing belt so as to surround the lens unit 17 and mask other parts.

When the index print is thus prepared, the shutter 15 is opened for a required exposure time to expose the index print. When the index print of the frame number 1 is exposed, the film F is advanced by one frame, and the positions of the lens unit 17 and the paper mask 16 are moved to the division positions on the print corresponding to the next frame number 2,
At that position, the index print of the frame number 2 is exposed. When the above-described exposure is successively performed on all the frames recorded on the film, the exposure of the index print is completed.

At the time of exposing each frame of the index print, the frame number may be simultaneously exposed by the liquid crystal display 28 of FIG. In this embodiment, the method of displaying the coma number is shown by a liquid crystal display. However, for example, a transparent film in which the coma number shown in FIG. 5 is written may be taken in and out of the optical path.

As described above, the lens unit 17
A variable exposure magnification lens is used in this embodiment. Therefore, the size of each section of the index print can be reduced or expanded to any size. With this function, for example, when creating an index print of the same size as one normal print, there are various types of film such as 12, 24, and 36 frames per film. Even if it is impossible to print one sheet when trying to print with the same size as that of 12 frames, it is possible to print one sheet by changing the exposure magnification.
