Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film carrier used in a photographic printing apparatus for printing a photo by printing a negative film.

[0002]

2. Description of the Related Art In a photographic printing apparatus for producing a print by performing a photographic printing process from a negative film to photographic paper, the negative film is held by a film carrier at a predetermined position where an image frame overlaps an opening for printing. By irradiating light through the printing opening, the printing paper is printed and exposed to produce a print.

In order to carry out this printing exposure under optimum conditions,
A mask plate having a printing opening of a size (shape) corresponding to a predetermined printing image area (mask area) of the negative film is provided, and this mask plate shields unnecessary peripheral portions of the image frame of the negative film. There is a need. As a result, the photometric data is not affected in parts other than the image to be printed, exposure control is stable, and flare does not occur in the image printed on the photographic paper due to the light in parts other than the image.

By the way, in recent years, the size of the image taken by the camera may be different on one negative film, for example, a panoramic image whose field of view is enlarged in the horizontal direction may be taken. The size of this panoramic image is shortened in the vertical direction (width direction of the negative film), and the ratio of the length in the horizontal direction to the length in the vertical direction is larger than usual (for example, about twice). .. Therefore, even when printing on photographic paper at the same scale for full size and panorama size, the enlargement (zoom) ratio when printing panorama size print frames is larger than the enlargement ratio when printing full size print frames. The mask area of the negative film is also different.
That is, it is necessary to change the mask area of the negative film according to each size.

For this reason, the film carrier used in the conventional photographic printing apparatus (see Japanese Patent Application No. 3-79682) has a main body portion of the film carrier for optimum printing processing corresponding to different print magnifications. A mechanism for changing the opening width of the provided exposure opening is provided, and the mask area of the negative film is changed according to the full size or panorama size.

However, since the mask area is usually fixed depending on the negative size to be printed, in a negative film in which a panoramic image and a full size image are mixed,
When printing a panoramic image, it was not possible to visually judge whether it was a full-size image or a panoramic image because the mask area was small.

Even in a photographic printing apparatus having an automatic determination function, if there is no difference between the base density and the image density (for example, an image of a night view), the determination accuracy of the full size image or the panoramic image is There was a misprint, not 100%.

[0008]

In consideration of the above facts, the present invention enables visual judgment of a panoramic image or a full size image from above a negative mask, and the mask area can be changed by the pressing operation of the negative film. The purpose is to obtain a film carrier that can be used.

[0009]

The film carrier according to claim 1 is for measuring a negative film in a film carrier of a photographic printing apparatus for printing a negative film in which a panoramic image and a full size image are mixed, and for exposing the negative film. When the negative film is pressed in the exposure opening,
It is characterized in that an opening changing means for changing the opening size of the negative mask is provided.

A film carrier according to a second aspect of the present invention is characterized in that the opening changing means operates at the same time when the negative film is pressed.

In the film carrier according to claim 3, the opening changing means sets the opening size of the negative mask to full size when the negative film is in a non-pressed state, and opens the negative mask when the negative film is in a pressed state. The feature is that the size is a panoramic size.

A film carrier according to a fourth aspect is characterized in that the opening changing means is provided on the side where the negative film is pressed to the exposure opening.

[0013]

In the film carrier according to the present invention, the opening size of the negative mask is changed by the opening changing means when the negative film is pressed in the exposure opening for photometric exposure and printing exposure of the negative film. Therefore, by making the opening size of the negative mask before the negative film is pressed larger than the panorama size, the operator can visually judge the image size even in the negative film in which the panoramic image and the full size image are mixed.

Further, since the opening changing means presses the negative film and operates by the pressing operation at the same time, a separate power source is required and the operator does not need to perform an extra operation. Furthermore, since the aperture size when pressed is a panoramic size, it is possible to shield unnecessary peripheral parts of the image frame of the negative film, so that the photometric data is not affected in parts other than the image to be printed, The exposure control is stable, and the deterioration of the finished print can be prevented.

Further, by providing the opening changing means on the side where the negative film is pressed in the exposure opening, it is not necessary to provide a complicated mechanism for changing the mask area in the exposure opening, which requires accurate focus position. Since it is good, the printing accuracy is improved and the cost can be reduced.

On the pedestal 300, a negative film conveying path 304 as a guide path is formed. An exposure opening 306 is provided at the center of the negative film transport path 304 in the longitudinal direction, and serves as an irradiation port for light rays from a light source 38 provided in the printer processor 10.

The size of the exposure opening 306 is the same as that of the full-size image frame 12A of the negative film 12. In the negative film transport path 304, transport rollers 308, 310, and 312 correspond to the back surface (lower surface) of the negative film 12 on the upstream side (left direction in FIG. 1) and the downstream side (right direction in FIG. 1) of the exposure opening 306. Are arranged. The transport rollers 308, 310, 312, 313 are driven in the same rotation direction at the same rotation speed.

The opening / closing cover 302 is pivotally supported by a bar 326 fixed to the pedestal 300 at a lower end of a cover body 324 having a housing shape, and can be opened / closed with respect to the pedestal 300 around the bar 326. ing.

A through hole 328 corresponding to the exposure opening 306 is provided at the bottom of the cover body 324.
In addition, the cover main body 324 is closed and the upper guide base 330 is provided at a position corresponding to the negative film transport path 304.
The negative film guide wall 332 is integrally formed, and a gap is formed between the tip of the negative film guide wall 332 and the bottom surface of the negative film transport path 304. Further, this gap dimension is slightly larger than the thickness dimension of the negative film 12, and secures the transport path at the end portion in the width direction of the negative film.

Between the guide wall 332 and the guide wall 332, the conveying rollers 308, 310, 312 and 31 are provided.
Corresponding to 3, idle rollers 334, 336, 338

An upper mask serving as a negative film holding means, which is relatively movable with respect to the upper guide base 330 and has an opening at a position corresponding to the through hole 328, in the central portion of the upper guide base 330 in the negative film conveying direction. 340 is arranged and attached to the mask base 342.

A bracket 260 is formed at the base end of the mask base 342. This bracket 260 is
The mask base 342 is axially supported by a bar 262 provided on the pedestal 300, and is biased in the opening direction by a torsion spring 264. On the other hand, an insertion groove 268 into which the plate-shaped support piece 266 of the upper mask 340 can be mounted is provided at the tip of the mask base 342. In addition, the mask base 342 is used when the cover body 324 is closed.
It corresponds to the solenoid 350 provided in the. Therefore, when the solenoid 350 is energized, the mask base 342 is attracted by the magnetic force, and the torsion spring 26
The upper mask 340 is brought into close contact with the exposure opening 306 of the negative film transporting path 304 against the biasing force of No. 4 to sandwich the negative film 12 positioned on the optical axis.

On the other hand, the opening 270 of the upper mask 340.
Are sized for full size, and support pins 272 are provided downward at four corners of the opening edge portion thereof to suspend the mask portion 274, as shown in FIGS. 2 and 3. .. The opening 275 of the mask portion 274 is made larger than the panoramic size, and the negative film 1 of the opening 275 is formed.
Bearing portions 276 are provided on both sides of the sheet 2 in the transport direction. The bent portion of the light shielding plate 280, which is substantially L-shaped in a side view, is rotatably supported by the bearing portion 276 so as to be rotatable. As shown in FIGS. 2 and 3, the light shielding plate 280 has a light shielding portion 280A which covers the mask portion 274 with the pin 278 as a fulcrum and is lighter than the weight portion 280B extending obliquely upward. Therefore, as shown in FIGS. 4 and 5, when the energization of the solenoid 350 is stopped and the upper mask 340 is lifted by the urging force of the torsion spring 264, the light shielding portion 280A jumps up in the arrow A direction.
It should be noted that the coil spring 282 inserted into the support pin 272 regulates this bounced state so as not to rattle.

Further, as shown in FIGS. 2 and 3, the upper mask 340 serves as the exposure opening 3 of the negative film transport path 304.
Negative film 12 that is in close contact with 06 and is positioned on the optical axis
The outer surface of the weight portion 280B is pedestal
0 exposure opening 306 abutting on the upper edge of the light-shielding portion 280A
Are closely attached to the mask portion 274, and the opening size thereof is set to a panoramic size.

The operation of the first embodiment will be described below with reference to the flow chart of FIG. It should be noted that this flow chart is applied when only the panoramic image is printed in the negative film in which the full size image and the panoramic image are mixed.

In step 500, the negative film 12 is moved frame by frame to position the image frame of the negative film 12 to be printed at the printing position. Next, step 50
In 2, it is judged whether the negative film 12 has been stopped at the printing position for a predetermined time (about 1 second). If the predetermined time has not elapsed, it is determined in step 504 whether the print start key button has been pressed. This key button is operated by the operator when the image frame is of panoramic size, but since the opening size of the mask is larger than the panoramic size, it is easy to see whether it is a full size image or a panoramic image on the mask. I can judge.

Next, at step 504, if the key button is pressed, at step 505 the solenoid 350 is pressed.
Energizes. As a result, the upper mask 340 is attracted by magnetic force, the weight portion 280B of the light shielding plate 280 contacts the edge portion of the exposure opening 306, and the light shielding portion 280A is brought into contact with the mask portion 2.
It is brought into close contact with 74 and its opening size is set to a panoramic size. Next, in step 506, photometry is performed and step 5 is performed.
The exposure amount is calculated at 08. Next, in step 510,
The printing process is performed, and in step 512, the solenoid 350
1 is stopped, the upper mask 340 is lifted by the urging force of the torsion spring 264 shown in FIG. 1, and the light blocking portion 280A of the light blocking plate 280 jumps in the direction of arrow A (see FIG. 4). As a result, the opening size of the mask portion 274 becomes larger than the panorama size. At step 514, it is judged whether or not one roll of the negative film 12 is finished,
In the case of negative determination, the process proceeds to step 500 to prepare for the next image frame printing. If it is determined in step 514 that the printing process of all the image frames has been completed (affirmative determination), the process ends.

If the print start key button is not pressed in step 502, the process proceeds to step 514.

As shown in FIG. 11, in the automatic determination, when the reject operation for skipping the image frame is not performed in step 501, it is determined in step 503 whether a predetermined time has elapsed and a predetermined time has elapsed. If so, the solenoid 350 is energized in step 505.
If the reject operation is not performed in step 501, the process proceeds to step 514.

As described above, in this embodiment, the types of image frames sequentially conveyed (full size or panoramic size)
Only the panoramic image is selected from the negative film 12
Since the printing opening has a panoramic size in synchronism with the press operation of, the work efficiency of the operator is improved.

Further, the light receiver 254 is used as the film carrier 2
When detecting the density information of the image photographed on the negative film 12 positioned at 20, it is possible to prevent the portion outside the image frame (the so-called blank portion of the negative film 12) from being metered, and the negative film is prevented. It is possible to accurately measure 12 images.

Further, since the light-shielding area for irradiating the negative film 12 is in an optimum state according to the print magnification of the negative film 12, the negative film 12 is exposed by printing under the optimum exposure condition according to the print magnification. Therefore, flare is prevented from occurring and the image quality is improved. Also, the printer dedicated to the panorama is unnecessary.

Next, the film carrier 28 of the second embodiment.
6 will be described. As shown in FIGS. 6 and 7, the second
Example embodiment film carrier 286 upper mask 288
A through hole 289 is formed at the tip of the moving pin 29.
0 is inserted. A stopper 291 is attached to the upper end of the moving pin 290 so that the moving pin 290 does not come out of the through hole 289. A mask portion 291 is suspended at the lower end of the moving pin 290. A spring 292 is arranged between the mask portion 291 and the moving pin 290, and biases the mask portion 291 in a direction away from the upper mask 288. A light blocking plate 293 is rotatably supported on the tip of the upper mask 288, and the tip of the light blocking plate 293 is in contact with the mask portion 291.

Now, the film carrier 2 of the second embodiment.
The operation of 86 will be described. Similar to the first embodiment, when the solenoid 350 shown in FIG. 1 is energized, the mask base 34
2 is attracted by a magnetic force and resists the biasing force of the torsion spring 264 to bring the mask portion 291 into close contact with the exposure opening 306 of the negative film transport path 304, and sandwich the negative film 12 positioned on the optical axis. At this time, the mask portion 291
The upper mask 3 has a face-to-face contact with the edge of the exposure opening 306.
The tip of 40 resists the biasing force of the spring 292,
The light blocking plate 293 is pressed downward. Therefore, the light shield plate 2
In 93, the opening size is reduced to have a panoramic size while the tip end slides on the mask portion 291. Thus, as in the first embodiment, the opening size is changed in synchronization with the pressing operation of the negative film, so that the work efficiency is improved.

In this embodiment, the upper mask 340
Although the mechanism for changing the opening size is provided on the side, it may be provided on the exposure opening 306 side. In each of the embodiments, the opening size is changed in synchronization with the negative press operation, but the opening size may be changed by separately providing driving means.

[0057]

As described above, the film carrier according to the present invention makes it possible to visually judge a panorama image and a full-size image from a negative mask, and the mask area can be changed by the pressing operation of the negative film.
