Description

Description: TECHNICAL FIELD The present invention relates to a film carrier used for printing an image on a film onto a photosensitive material.

(Background technology)

Generally, a film carrier is used when printing a developed image on a photographic paper after developing a negative film.

Among these film carriers, not only long films having a large number of exposures but also short films cut every four to seven exposure images can be quickly arranged on a printing optical axis.

In such a film carrier, the operator selects a printing exposure while moving the negative film in the left-right direction in front of the printing operator, and when the printing exposure reaches the printing position, the pressing plate is brought into close contact with the lower mask to make these exposures. After sandwiching the negative film between them, printing work is performed. When the printing image exposure is half size, the film carrier is rotated by 90 degrees around the optical axis, and the printing operation is performed while moving the negative film from the back side of the worker to the front side or the opposite direction. Become.

However, in such a half-size printing state, the edge of the image exposure arranged at the printing position in the transport state of the negative film in the longitudinal direction is obstructed by the opening edge of the pressure-bonding plate floating apart from the lower mask and visually observed. Can not do it.
Therefore, it is necessary for the operator to adjust the edge of the half-size image exposure to the edge of the lower mask by relying on intuition, which may cause edge printing failure of the image exposure in a printed state.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a film carrier capable of printing both full-size and half-size image exposures, without causing edge breakage even in a half-size printing state.

[Means for solving the problem]

The present invention relates to a film carrier for transporting a film and providing a mask corresponding to the size of a printed image between the film and a photosensitive material on which the image of the film can be printed. An opening enlarging means for partially enlarging the opening edge along the direction is provided, and the position of the film is confirmed through the opening enlarging portion.

For this reason, in the present invention, in the half-size printing state, the half-size edge portion can be visually observed through this opening enlarging means, and the half-size edge portion is surely matched with the printing opening of the lower mask to prevent the edge cutting of the image. can do. Further, since the edge of the portion other than the opening enlarging means corresponds to the edge of the half-size image exposure when the pressure-bonding plate is pressed, the edge can be confirmed even in the pressed state.

As the opening enlarging means, a notch may be directly formed in the printing opening of the crimping plate, or an adapter may be attached to the full-size image printing opening and a notch may be formed in the half-size image opening provided in the adapter. .

The opening enlarging means is not limited to being provided on the pressure-bonding plate, but may be provided on a mask fixedly arranged with respect to the lower mask. In this case, the mask is provided with a pair of arms having a printing opening between the opposing ends, and a notch is formed at the ends of these arms to form the opening enlarging means.

(Example of the invention)

FIGS. 1 to 4 show an embodiment of a film carrier 10 to which the present invention is applied. This film carrier
In 10, a film guide groove 14 having a rectangular cross section is formed at a substantially central portion of the base plate 12, and is used for running the film F. The film F is guided in the direction of arrow A in FIG. The worker is the arrow A in FIG.
The operation is performed in a direction perpendicular to the direction (the direction of arrow S).

As shown in FIG. 4, the base plate 12 has
, The pivot plate 26 is pivotally supported. This swivel plate
A pivot plate 28 is coaxially supported by the pin 24 on the pivot 26. The turning plate 26 is locked to the base plate 12 by a latch 27, and the turning plate 28 is urged upward by a torsion coil spring 29 around the pin 24 in FIG. An upper mask 32 is attached to the tip of the turning plate 28.
The upper mask 32 has a rectangular planar shape and an opening 32A.
Are formed, and support the pressure bonding plate 33. The crimping plate 33 has pins 34 erected from four corners thereof penetrating the upper mask 32, and a stopper 36 is attached to a tip end thereof. A compression coil spring 38 is mounted between the upper mask 32 and the pressure plate 33, and receives a biasing force in a direction in which the pressure plate 33 separates from the upper mask 32, that is, downward in FIGS. .

The solenoid 42 fixed to the turning plate 28 generates an exciting force between the solenoid 42 and a shaft 44 projecting from the turning plate 26. In the traveling guide state of the film F, the first
As shown in FIG. 4 and FIG. 4, since the revolving plate 28 is raised by the urging force of the torsion coil spring 29, the upper mask 32 and the crimping plate 33 are arranged separately from the bottom surface of the film guide groove 14. When 42 generates an exciting force, the revolving plate 28 is separated from the revolving plate 26, and the pressure plate 33 is pressed against the bottom of the film guide groove 14 against the urging force of the compression coil spring 38, and the film F is held therebetween. It is designed to be pinched. The opening 46A of the lower mask 46 has a full-size or half-size printing opening area.
However, FIGS. 1 and 4 show a state in which a half size is selected from the openings 46A.

In this embodiment, as shown in FIG. 3, a cut-out portion 33B is formed in a part of a rectangular half-size printing opening 33A formed in the pressure bonding plate 33, and a part of the printing opening 32A is enlarged (width dimension). W) Yes. The notch 32B is formed at the opening edge of the printing opening 32A along the longitudinal direction of the film F (the left-right direction in FIG. 3). The half-size opening 33A is rotated by 90 degrees in the longitudinal direction with respect to the full-size image exposure. When printing a full-size image exposure, the pressure plate 33
Is replaced with a crimping plate having an opening (33C) of the size of a full-size image exposure, and the lower mask 46 is similarly replaced.

 Next, the operation of the present embodiment will be described.

The film F is transported in the direction of arrow A through the film guide groove 14.

Crimping plate 3 with opening 33C for full size image printing
3 is selected, and the worker can use the film F through the printing opening 33C.
After aligning the image exposure with the printing optical axis P, the solenoid 42
Is applied to bring the pressure bonding plate into close contact with the lower mask 46, and then a printing operation is performed.

Next, when printing a half-size image, the crimping plate having the printing opening 33C for the full-size image is removed.
A crimping plate 33 having an opening 33A is attached to the turning plate 28 as shown in the figure. Then, the film carrier 10 is rotated around the printing optical axis P in the direction of arrow B. For this reason, the notch 33B of the printing opening 33A is arranged on the side of the printing operator.

Here, as shown in FIG. 1, when the film F is transported, the pressure bonding plate 33 is floated together with the revolving plate 28, and the film F can be transported between the film F and the lower mask 46. In this state, the worker moves the arrow L (at an angle of 45 degrees with respect to the horizontal line).
The edge of the half-size image exposure of the film F is securely opened through the notch 33B as shown in FIG.
Can be confirmed, and the edge of the half-size image exposure can be accurately placed in the opening 46A when the pressing plate 33 is pressed by the excitation of the solenoid.

On the other hand, since the notch 33B is not provided in the related art, the edge of the printing opening 33A hinders the edge of the half-size image exposure from being viewed in the arrow L direction. For this reason,
There is a state where the half-size image exposure is not accurately placed on the edge of the opening 46A, and the edge of the image printed on the photosensitive material at the time of printing is not printed accurately, which causes so-called edge breakage.

Next, FIG. 5 shows a crimp plate 33D used in the second embodiment. In this embodiment, a projection 52 corresponding to the cutout 33B protrudes from the printing opening 33A in a direction to reduce the area of the printing opening 33A. The tip of this projection 52 is the projection 5 of the opening 33A.
Opposite one side where 2 is not provided, a space between them is a printing opening for a half-size image. In the printing opening 33A of this embodiment, the portion excluding the projection 52A is the cutout 33 of the above embodiment.
It is equivalent to the longitudinal dimension W including B. Therefore, in this embodiment, the edge of the half-size image can be confirmed through the gap 52A formed on both sides of the projection 52.

 Next, FIG. 6 shows a third embodiment of the present invention.

In this embodiment, a full-size printing opening of the upper mask 33 is used.
Adapter 56 is shown for insertion engagement with 33C. The adapter 56 has a main body 56A having an outer diameter dimension to be engaged with the printing opening 33C. The main body 56A has a dish shape with an open top surface, a rectangular shape in plan view, and a vertical wall from four sides thereof.
58 is projected and fitted into the opening 33C of the upper mask 33. An opening 61 is formed in the center, and this opening 61 is equivalent to the opening 33A in the first embodiment. The opening 61 has a cutout 61A formed in the long side thereof in the direction of increasing the dimension between short pieces, so that the opening 61 has a function similar to that of the above-described embodiment.

The upright wall 58 is inclined so that the facing dimension increases toward the upper end. As a result, the shape does not obstruct printing light that expands from the light source below to the photographic paper above.

The extension plates 63 and 64 protrude from the main body 56A, and come into contact with the crimping plate 33 to prevent the main body 56A from dropping. Connecting portions 63A, 64A of extension plates 63, 64 to standing wall 58
Is engaged with the inclined standing piece 33F of the crimping plate 33 and is held by the crimping plate 33. The arm 65 protrudes from a part of the extension plate 64 and is used for gripping when the main body 56A is taken out.

Therefore, in this embodiment, half-size printing can be performed by simply attaching the adapter 56 to the full-size printing press plate without using a half-size printing press plate. In addition, there is no possibility that the notch 61A may cause the edge to be cut off at the time of half-size printing.

The width of the opening 66 indicated by the imaginary line in FIG. 6 is about half the width of the full-size image, and the longitudinal dimension is the length of the full-size image. So this opening
By attaching the adapter 56 with the 66 formed to the crimping plate 33, the upper and lower sides of the full-size image are covered, so that a printing opening (called a panorama-size image) whose width is much larger than its height can be formed. it can. By using the adapter 56 having such a super-horizontal opening 66, it is possible to print images of various panoramic sizes without providing a special adapter.

Next, FIGS. 7 to 9 show an adapter 67 used in a fourth embodiment of the present invention. Adapter 67 of this embodiment
Is mounted on the revolving plate 26 and is arranged at a constant distance from the lower mask 46 without vertically moving unlike the above-described embodiments.

In the adapter 67, an opening 68A is formed at the center of the rectangular plate 68, and a pair of projections 70 project from the rectangular plate 68 corresponding to the peripheral back surface of the opening 68A. The projections 70 are formed on the back surfaces on both sides of the opening 68A.
Can be engaged with the inner edge of the short piece of the opening 26A.

A pair of arms 72 and 73 are fixed to the surface of the rectangular plate 68 at a portion corresponding to the protrusion 70. The arms 72 and 73 are bent at the middle part, and the tip horizontal parts 72B and 73B are reduced in height and approached to each other so that the opening 26A and the upper mask 3 are formed.
Through the opening 32A of the second, the full size baking opening 33C of the crimping plate 33
Has entered. A notch 73A is formed in the horizontal end portion 73B of the arm 73, and has the same function as the notch 33B and the notch 61A in each of the above embodiments.

Therefore, also in this embodiment, the adapter 67 is
A half-size image printing mask can be formed only by attaching it to the opening 26A, and the notch 73A allows accurate positioning, so there is no risk of edge breakage. In this case, the printing opening is formed between the distal ends of the arms 72 and 73,
The other two sides not defined by these arms 72 and 73 are defined by openings 33C (see FIG. 6) of the pressure plate 33.

〔The invention's effect〕

Since the present invention is configured as described above, the present invention has an excellent effect of preventing the image from being cut off at the time of half-size printing.
