Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a magazine for a photosensitive material in which a long photosensitive material is wound up and stored in layers.

[Prior art]

Photo printing equipment has a large number of print channels prepared in advance, and determines the coefficients and constants of the exposure calculation formula according to the selected print channel, and prints photos with appropriate density and good color balance. The exposure amount is controlled to achieve the perfect finish. This print channel is determined by a combination of paper balance, lens balance, film balance, etc. The vapor balance represents the type of photographic paper, and is determined by a combination of sensitivity, emulsion type, surface type, manufacturer, serial number, etc. Further, the lens balance represents the type of lens, and is determined by a combination of printing magnification, aperture F value, etc. Film balance represents the type of photographic film, for example, color negative film, and is determined by a combination of manufacturer, sensitivity, size, etc.

However, with conventional photoprinting machines, when changing the vapor magazine containing photographic paper, the paper balance must be manually adjusted by manually creating one t'A print, making the input operations cumbersome. There is also a risk of erroneous operation.

For this reason, when a vapor magazine is loaded, the paper balance information indicating the type of photographic paper displayed by a combination of barcodes and unevenness on the boat part of this vapor magazine is automatically read, and the paper balance information indicating the type of photographic paper is automatically read. It has been proposed to change the printing conditions of printers (Japanese Patent Application Laid-open No. 6L-
(See Publication No. 106448). According to this, since manual operation is not necessary, operability is improved.

However, with the above configuration, if the magazine is a packaging container or a special magazine, the display and the photographic paper inside will not differ, but if it is a refillable magazine, the photographic paper loaded may be incorrect or the display If you forget to change it, you may receive an incorrect display, which may cause you to set the burning conditions incorrectly.

On the other hand, as a technology to identify all film characteristics such as film speed, film type, expiration date, sensitivity, latitude, etc., a binary code representing the above characteristics is punched along the edge of a 35 mm roll film between the edge sprockets. It is known to be applied in combination with and without RESEAR.
CHDISCLO3URE Apri11980 No

ilm coding).

This technology was applied to display information on photographic paper, and numbers set for each type of photographic paper, such as photosensitive characteristics, image quality, manufacturer, size, etc., were displayed on the leading edge of the paper in a form that could be converted into electrical signals. It has been proposed to attach a bunch mark, automatically read this mark, store it in advance, and perform the optimal processing for the type of photographic paper according to certain data (Japanese Patent Application Laid-Open No.
2-286040). According to this, since information about the photographic paper is written on the photographic paper itself, there will be no erroneous display even if the paper is refilled.

[Problem to be solved by the invention]

However, with this configuration, information about the photographic paper can only be applied to the leading edge of the photographic paper, so if the magazine is replaced with a magazine loaded with a different type of photographic paper during use, the photographic paper that is in the middle of use may be reloaded. When using a magazine, for example, the middle of the photographic paper becomes the leading edge, so information about the photographic paper cannot be obtained, and it is necessary to devise a way to match the loaded photographic paper with the magazine.

In consideration of the above facts, the present invention provides a magazine for photosensitive materials that can identify information regarding the photosensitive materials loaded in the loaded magazine even if the magazine is replaced or the photosensitive materials are refilled during use. That is the purpose.

Note that the driving of the pull-out roller 46 and the feeding roller 48 is controlled by signals from the control section 22 via drivers 43 and 47, respectively. In addition, the reel 4 of the winding magazine 36
0 is rotated by the driving force of a driver 41 connected to the control section 22, and sequentially winds up the color photographic paper 28 corresponding to the exposure amount.

As shown in FIG. 2, a punch hole 62 is provided at the leading end of the color photographic paper 28 to indicate characteristic information of the color photographic paper 28, such as the type, size, serial number, manufacturer, etc. . A plurality of rows of punch holes 62 are provided in the width direction of the color photographic paper 28, and each punch hole 62 is provided in a plurality of rows in the width direction of the color photographic paper 28.
It corresponds to the serial number and manufacturer. Further, the type, size, serial number, and manufacturer of the punched holes 62 are specified by the number of consecutive punch holes 62 in the longitudinal direction of the color photographic paper 28.

A light projecting section 64A and a light receiving section 64B of the photoelectric sensor 64 are arranged in the supply magazine 34 so as to sandwich the passage path of the bunch hole 62 therebetween.

The photoelectric sensor 64 is connected to a control unit 66 installed in the supply magazine 34. Control section 6
6 is equipped with a memory 68. Here, when the color photographic paper 28 is conveyed and its leading end passes between the light projecting section 64A and the light receiving section 64B, the punched holes 62 are detected by the photoelectric sensor 64, and the number of punch holes 62 is counted by the control section 66. The data is stored in the memory 68.

This photoelectric sensor 64 is set to operate only for a predetermined period of time during which the leading edge of the color photographic paper 28 in the initially installed supply magazine 34 passes.

Also, the color photographic paper 2 in this supply magazine 34 is

An opening/closing sensor 70 for detecting the open/closed state of the lid 34A is attached near the lid 34A that is opened during refilling, and its signal line 72 is connected to the control section 66. When the opening/closing sensor 70 detects the open state of the lid 34A, the contents stored in the memory 68 are erased.

The control section 66 is also provided with a display section 74, which has the role of displaying the contents stored in the memory 68. Further, the control section 66 is provided with an information output section 75, and the receiver of the supply magazine 34 is adapted to correspond to the reading sensor 72 connected to the control section 22 when it is placed on the stand 42.

In the control unit 22, when the supply magazine 34 is placed on the tray 42, the reading sensor 72 reads the information stored in the memory 68 of the control unit 66, and determines the characteristics of the color photographic paper 28 to be applied. It is now possible to recognize it.

The operation of this embodiment will be explained below.

When a light beam is emitted from the white light source 12, the light beam is diffused by passing through the diffusion tube 18 and reaches the printing position. One frame of a negative film 16 held by a negative carrier 14 is positioned at the printing position, and the light beam passes through this negative film 16. The transmitted light beam is focused by the lens 26 and formed into an image on the color photographic paper 28 when the shutter driver 32 opens the shutter 30.

Also, when it comes to the exposure time of each color, each filter 2
0 is inserted onto the optical path by the filter driver 24, and the color corresponding to the inserted filter 22 is cut.

When a predetermined exposure time has elapsed, the shutter drive unit 32 inserts the shutter 30 onto the optical path to block the optical path. Thereby, the image recorded on the negative film 16 can be printed onto the color photographic paper 28.

Here, the exposure time is calculated based on image density, lens balance, film balance, and paper balance. That is, the coefficients and constants of the arithmetic expression differ depending on the lens balance, film balance, and paper balance.

The image density is defined as C
By receiving the light with the CD sensor 76, it is possible to understand the words. The transmitted light beam received by the CCD sensor 761 is photoelectrically converted and supplied to the control section 22 . The control unit 22 calculates the exposure time of each color based on the supplied signals. The balance, film balance and lens balance can be set using the dials 82 and 84 on the operation panel 80.
is set based on the operating position.

The paper balance differs depending on the supply magazine 34 placed on the tray 42. The paper balance setting procedure will be explained below according to the flowcharts of FIGS. 3 and 4.

First, the correspondence between the supply magazine 34 and the color photographic paper 28 stored therein will be explained with reference to FIG.

In step 100, the lid 34A of the supply magazine 34
It is determined whether or not it has been released. In case of negative judgment,
It is determined that the color photographic paper 28 in the supply magazine 34 has not been refilled, and a standby state is entered until an affirmative determination is made. Here, when the lid 34A is opened, the process moves from step 100 to step 102, the information stored in the memory 68 of the control section 66 is cleared, and the process moves to step 103. In step 103, when it is determined that the refilling of the color photographic paper 28 into the supply magazine 34 is completed and the lid 34A is closed and the receiver is placed on the stand 42, the color photographic paper 28 is pulled out by the bowing roller 46. Then, in step 104, the punched hole 62 is detected by the photoelectric sensor 64. In the next step 106, information corresponding to the number of detected bunch holes 62 is read out and stored in the memory 68.

In the next step 108, the stored information is displayed on the display section 74.
will be displayed. Thereby, the paper balance of the color photographic paper 28 in the supply magazine 34 can be specified. Furthermore, when the lid 34A is opened, the information stored in the memory 68 is canceled and is rewritten with information corresponding to the color photographic paper 28 that was refilled when the color photographic paper 28 was transported after being loaded into the photoprinting device 10. Therefore, it is possible to always match the stored contents and displayed contents with the information on the color photographic paper 28 actually stored.

Next, according to the flowchart in FIG.
The correspondence between O and the supply magazine 34 will be explained.

First, in step 200, it is determined whether the supply magazine 34 is placed on the tray 42 or not.

When it is determined in step 200 that the supply magazine 34 has been placed on the tray 42, the process proceeds to step 202, where the control unit 22 reads information stored in the memory 68 of the control unit 66. Then, in step 204, a paper balance is set based on the read division.

In the next step 206, the film balance and lens balance are read out, and then the process moves to step 208, where the print channel is set from the film balance, lens balance, and vapor balance. The printing process is performed in this printing channel until the receiver is removed from the stand 42.

In this way, the supply magazine 34 stores information about the stored color photographic paper 28 until the color photographic paper 28 in the supply magazine 34 is refilled. Even after replacement, the new receiver can read information on the color photographic paper 28 stored in the supply magazine 34 placed on the stand 42. In addition, since the supply magazine 34 displays the characteristics of the color photographic paper 28 stored in its display section 74,
It becomes easy to select the supply magazine 34 that stores the color photographic paper 28 having the required characteristics from among the plurality of stocked supply magazines 34.

On the other hand, the contents stored in the memory 68 of the supply magazine 34 are cleared by opening the lid 34A, and the contents stored in the memory 68 of the supply magazine 34 are cleared by the next printing device l.
Since the punch holes 62 are newly detected and the information is stored during transportation after being attached to the O, there is no possibility that erroneous information will be stored.

In this embodiment, a punch hole 62 is punched in the color photographic paper 28 and is read by a photoelectric sensor 64, but the punch hole 62 may be read by a mechanical sensor such as a counter. In addition, a bar code or a mark with unevenness may be used as a mark corresponding to information. In the case of a bar code, a bar code reader is installed in place of the photoelectric sensor 64, and in the case of an uneven pattern, a limit switch is installed, and each All you have to do is detect the mark.

Further, the display on the display section 74 may be an electrical display such as an LCD display or an LED display, and as shown in FIG.
It may be displayed mechanically. That is, the sixth
As shown in the figure, the display unit 74 has two drum-shaped rotary indicators 91 and 92 housed in its casing 90.
It is pivotally supported by the casing 90 via a shaft 93. The type of color photographic paper 28 that can be loaded into the supply magazine 34 is displayed in advance on the circumferential surface of the rotation indicator 91. Here, the types of color photographic paper 28 include glossy, silk, raster matte, metallic, and crystal. On the other hand, a plurality of paper width dimensions of the color photographic paper 28 that can be loaded into the supply magazine 34 are displayed on the circumferential surface of the rotary display 92. Here, the paper width dimensions of the color photographic paper 28 are 102 mm and 117 mm.
, 127mm, etc.

The rotation indicators 9192 are rotated about the shaft 93 in correspondence with the number of swing movements of the lever 94, respectively. That is, the rotation indicators 91 and 92 are connected to the lever 94.
The lever 94 is rotated by a certain amount with one swing, and the lever 94 is rotated by the number of times the lever 94 swings. A roller 95 is attached to the tip of the lever 94, and is normally placed on the conveyance path of the color photographic paper 28. Therefore, depending on the presence or absence of the punch holes 62 provided at the tip of the color photographic paper 28, the lever 94 is activated, and depending on the number of activations, the rotation indicators 91, 92 are rotated by a predetermined amount, and the number of punch holes 64 is determined. Displays of the corresponding types and paper width dimensions are arranged at corresponding positions on the upper surface of the casing 90. A rectangular hole 96.97 is provided on the upper surface of the casing 90 to correspond to the rotation indicator 91.92.
You can visually see the corresponding display on the top surface.

After the leading edge of the color photographic paper 28 has passed, the lever 9
4 is retracted from the conveyance path of the color photographic paper 28. Note that the lever 9 should be adjusted to such an extent that the color photographic paper 28 will not be damaged even if it comes into contact with the color photographic paper 28.
If the operating force of 4 is weakened, there is no need to evacuate.

Furthermore, in this embodiment, the punch holes 62 are formed on the color photographic paper 28.
However, as shown in FIG. 5, a leader 80 may be attached to the leading end of the color photographic paper 28, and a punch hole 62 may be punched into the leader 80. In this case, it is possible to remove only the leader 80 and reuse the same information on the color photographic paper 28, and it is also possible to handle the color photographic paper 28 without having to punch holes 62 in all of it.

〔Effect of the invention〕

As explained above, the magazine for photosensitive materials according to the present invention is
Even if the magazine is replaced or the photosensitive material is refilled during use, it has the excellent effect of being able to specify information regarding the photosensitive material loaded in the magazine.
