Abstract

PURPOSE:To cope with printed image frames having different sizes by allowing a lamp case and a character imprinting film to be adhered to a photosensitive material by an elevating mechanism when it reaches a prescribed position and printing a character for the film at the edge of the photosensitive material by a lamp in a lamp case. CONSTITUTION:When a photographic paper F stops at a required position, a motor 34 reversely rotates to lower an elevating bracket 32. The lamp case 44 allows a litho film 52 to be closed to the edge of the photographic paper F and then to be adhered to it. By lighting an image printing light source, an image on a negative film is printed onto the photographic paper F. Simultaneously, the light source 48 in the lamp case 44 is lit to print a character on the litho film 42 onto the edge of an image P. Consequently, the printed image frames having different sizes can be handled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character-inserting photographic printing apparatus that inserts characters into the ends of the printing frames during printing of a photosensitive material.

[Conventional technology]

In a printing device that inserts characters at the edge of the printed image frame,
A character insertion device is attached to a part of a fixed mask that defines the printing range of image frames.

However, since this fixed mask has a fixed size of image frame to be printed, when printing an image of a different size onto photographic paper, it is necessary to replace this fixed mask with a fixed mask having a different printing range. Furthermore, when printing a photograph that does not require character insertion, the character insertion device must be removed from the mask.

[Problem to be solved by the invention]

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to provide a text-embedded photo printing apparatus that can handle printed image frames of different sizes.

[Means to solve the problem]

The present invention provides a variable mask corresponding to an end of a photosensitive material and defining a printing range by coming into contact with and separating from the photosensitive material; a lamp case attached to the variable mask and corresponding to an end of the photosensitive material;
The character imprinting film attached to the end of the lamp case on the photosensitive material side and the lamp case are moved relative to the variable mask, and when the photosensitive material is transported, the character imprinting film is separated from the photosensitive material and transferred to the photosensitive material. The present invention is characterized by having an elevating mechanism that allows the character printing film to be brought into close contact with the photosensitive material during character printing.

For this reason, in the present invention, when the photosensitive material is brought into a conveying state, the letter printing film is moved relative to the variable mask together with the lamp case using a lifting mechanism to convey the photosensitive material. When the photosensitive material reaches a predetermined position, the lamp case and the character-printing film are brought into close contact with the photosensitive material by the lifting mechanism, and the characters on the character-printing film are printed onto the edges of the photosensitive material by the lamp inside the lamp case.

[Embodiments of the invention]

1 to 3 show a photographic printing apparatus 10 to which the present invention is applied.

In this photographic printing apparatus 10, photographic paper F, which is a photosensitive material, is sent in the direction of the arrow from a storage section (not shown), and an image P is printed at a printing position by a printing light source (not shown) and a negative film, as shown in FIG. It has become.

This photographic paper F is formed into a long sheet, on which a plurality of images P are successively printed in the longitudinal direction, and then cut into individual images in the next step (not shown).

Variable masks 12 and 14 are arranged on the transport path of the photographic paper F in the direction indicated by the arrow, corresponding to both ends of the photographic paper F in the width direction. These variable masks 12.14 have step portions 12A, 14
A is a mounting surface that guides the edge of the photographic paper F in the width direction. Further, the variable mask 12.14 has stepped portions 12A, 14A.
The extension parts 12B and 14B are projected substantially parallel to the photographic paper F.
Both widthwise ends can be covered.

That is, the variable masks 12, 14 are moved in parallel in the direction toward each other (direction of arrow B) and in the direction away from each other by a driving means (not shown), and when they move in the direction toward each other, the extension portions 12B, 14B covers the ends of the photographic paper F in the width direction to form a bordered image having an unprinted portion at the end of the printed image of the image P.

Further, a pair of variable masks 16 (however, one variable mask is not shown in FIG. 1) is separably provided on the photographic paper F at the printing position from the upstream and downstream sides of the image P. ing. These variable masks 16 are moved toward and away from each other by driving means (not shown) to determine the printing range of the image P. Therefore, one end of a flexible mask 18 is fixed to the variable mask 16, and the other end of the flexible mask 18 is rolled up and accommodated.

Note that by moving the flexible mask 18 forward or backward by a slight amount in the printing state, it is possible to distinguish between a bordered image and a green-tinted image.

As shown in FIG. 3, the variable mask 12 has a bracket 2.
1.22 is fixed, and a rotary arm 24 is pivotally supported on this bracket 22 via a shaft 23. A vertical wall 26 of a support arm 26 fixed to this rotating arm 24
A support shaft 28 passes through A with its axis perpendicular. An upper flange portion 32A and a lower flange portion 32B of a lifting bracket 32 are fixed to both upper and lower ends of the support shaft 28. As a result, the lifting bracket 32 can be slid in the vertical direction (in the direction of arrow C) by moving the support shaft 28 relative to the vertical wall 26A.

Also, the output shaft 3 of the motor 34 is fixed to the support arm 26.
An eccentric cam 36 is fixed to 4A, and inserted into a horizontally long window 32C formed in the elevating bracket 32.

Therefore, when the motor 34 rotates, the elevating bracket 32 moves up and down.

Both upper and lower ends of a support shaft 38 whose axis is perpendicular are fixed to the upper flange portion 32A1 and the lower flange portion 32B. These support shafts 38 pass through the support bracket 42.

A lamp case 44 is fixed to the support bracket 42, and a compression coil spring 46 is attached between the top of the support bracket 42 and the upper flange portion 32A.

The lamp case 44 has a box shape, and a light source 48 for printing characters is housed therein, and a lithium film 52 on which characters for insertion are previously formed is attached to the lower transparent portion.

This lith film 52 is located at the edge of the photographic paper F on the stepped portion 12A when the elevating bracket 32 is lowered.
By pressing 2 and turning on the light source 48, the characters formed on the lithographic film 52 can be exposed. When the elevating bracket 32 is in the lowered state, the lamp case 44 can be lifted by bending the compression coil spring 46, so that the squirrel film 52 can be brought into close contact with the photographic paper F by the force of the compression coil spring 46.

Next, the operation of this embodiment will be explained.

Since the bracket 22 can be rotated about the shaft 23 in the direction of the arrow in FIG. 1, the operator can attach the lithographic film 52 on which the necessary characters are printed to the lamp case 44.

The bracket 22 is returned to the state shown in FIG. 2.3 by rotating it in the direction opposite to the direction of the arrow.

When the leading edge of the photographic paper F is automatically fed in the six directions of the arrows, the pair of flexible masks 18 are brought close to each other to prevent the leading edge of the photographic paper F from being lifted up due to curling, and the stepped portions 12A, 14A are moved. A transportation path for the photographic paper F is formed between the flexible mask 18 and the lamp case 4 by rotating the motor 34 to raise the lamp case 44 significantly.
Prevent interference with 4.

When the photographic paper F is stopped at the required position, the motor 34 is reversed, the elevating bracket 32 is lowered, and the lamp case 44 brings the squirrel film 52 into close contact with the end of the photographic paper F.

Here, an image on a negative film (not shown) is printed onto photographic paper F by turning on an image printing light source (not shown). At the same time, the light source 48 in the lamp case 44 is turned on to print 520 characters on the lith film onto the edge of the image P.

When the printing operation is completed, the motor 34 is reversed to raise the lamp case 44 by a slight amount to separate the lith film 52 from the photographic paper F. As a result, the photographic paper F can be conveyed again, and the next printing position is selected. Thereafter, the above operations are repeated to sequentially print images and characters.

In the above embodiment, the lamp case 44 is arranged at the end of the photographic paper F via the bracket 22, the rotary arm 24, the support arm 26, etc., but the elevating bracket 32 may be directly fixed to the variable mask 12. You may also do so.

〔Effect of the invention〕

Since the present invention has the above-mentioned structure, it has an excellent effect that it is possible to insert characters into the edge of a photosensitive material even in a printing apparatus capable of changing the size of a printed image.
