Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a photographic printing device that prints an image of an original film onto a photosensitive material, a magazine for photosensitive material that winds up and accommodates a long photosensitive material in layers, and The present invention relates to a photographic printing method that controls printing exposure according to information indicating the characteristics of a photosensitive material.

[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, and serial number. In addition, the lens balance is
This indicates the type of lens, which 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, in conventional photo printing machines, when changing the paper magazine containing photographic paper, the operator has to create an operation panel and manually enter the vapor balance, which is cumbersome and prone to erroneous operation. There is also a fear that

For this reason, when a paper magazine is loaded, it automatically reads the paper balance information indicating the type of photographic paper displayed by a bar code or a combination of unevenness on the boat part formed on this paper magazine, and responds accordingly to this information. It has been proposed to change the printing conditions of printers (Japanese Patent Laid-Open No. 62
(Refer to 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, an incorrect display may be displayed, and the burning conditions may be set incorrectly.

On the other hand, as a technology to specify film characteristics such as film speed, film type, expiry 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 (RBStEA).

The characteristics of the color photographic paper 28 to be read and applied can be recognized.

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
It can be recognized by receiving light with the CD sensor 76. The transmitted light beam received by the CCD sensor 76 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. Further, the film balance and lens balance are set based on the operation positions of the dials 82 and 84 on the operation panel 80.

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, in the control section 66 of the supply magazine 34, the supply magazine 34 and the color photographic paper 2 stored therein are shown.
8 will be explained with reference to FIG.

In step 100, it is determined whether the lid 34A of the supply magazine 34 is opened. Here, if it is determined that the lid 34A is opened, the process moves from step lOO to step 102, and the memory 68 of the control unit 66
Clear the information stored in , and then step 104
The lid 34A is closed and the supply magazine 34 is placed on the stand 4.
If it is determined that the photo printing apparatus 10 has been placed on the printer 2, the process moves to step 108, and the input/output section 75 reads the signal output from the output section 52 of the photo printing apparatus 10. This output unit 52 outputs information that sets the receiving magazine 34 for supply based on the punched hole 62 detected after it is placed on the stand 42 . This will be discussed later.

In the next step 110, the read information is stored in the memory 6.
The information stored in the memory 68 is then displayed on the display section 74 at step 112. 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 this memory 68 is canceled, and the color photographic paper 28 after being loaded into the photographic printer IO is
Since the information is rewritten to correspond to the color photographic paper 28 that has been repacked during transportation, the stored and displayed contents can always match the information on the color photographic paper 28 that is actually stored.

Next, according to the flowchart in FIG. 4, the photo printing apparatus 1
The correspondence between the photoprinting device IO and the supply magazine 34 in the control unit 22 of FIG.

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 it is determined whether the punched hole 62 has been detected by the photoelectric sensor 64. Here, if it is determined that the punched hole 62 has been detected, the process moves to step 204 to search for information on the color photographic paper 28 based on the detected punched hole 62, and output a signal corresponding to this information. After outputting to section 52 (
Step 206), then proceed to step 208.

Further, if the punch hole 62 is not detected in step 202, it is determined that the leading edge of the color photographic paper 28 has already been used and the color photographic paper 28 is in use, and step 207
The reading sensor 7 is output from the input/output section 75 of the control section 66.
2 reads the information stored in the memory 68, and in step 2
Move to 08. In step 208, the photo printing device 1
The information read in step 0 is displayed on the display unit 52, and the process moves to step 210.

In the next step 210, the paper balance is set based on the read information, and then in step 7'212, the film balance and lens balance are read out.

In the next step 214, the film balance, lens balance, paper balance, or rough flint channel is set, and thereafter, the printing process is performed in this print channel until the supply magazine 34 is removed from the pedestal 42 in step 216. .

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 1.
0, the photoprinting device IO side newly detects the bunch hole 62, reads and stores the information, and if the leading edge of the color photographic paper 28 has already been used, it from the magazine 34 to the photo printing device l
Since the information stored in the O memory 68 is output, the information on the color photographic paper 28 loaded in the supply magazine 34 can always match the information recognized on the photo printing apparatus 10 side.

In this embodiment, bunch holes 62 are punched in the color photographic paper 28 and read by the photoelectric sensor 64, but it 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, color photographic paper 2
The paper width dimensions for 8 are 102+mm and 117mm.
, 127mm.

The rotation indicators 91 and 92 are rotated about the shaft 93 in correspondence to the number of swinging movements of the lever 94, respectively. That is, the rotation indicators 91 and 92 are the same as the lever 9.
It is designed to rotate a certain amount with one swing of 4.
The lever 94 is rotated twice as many times as the number of 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. For this reason, the punch hole 62 provided at the tip of the color photographic paper 28
The rotation indicators 91 and 92 are rotated by a predetermined amount depending on the presence or absence of the punch holes 64, and the display of the type and paper width dimension corresponding to the number of punch holes 64 is arranged at a position corresponding to the upper surface of the casing 90. On the upper surface of the casing 90 are the rotation indicators 91 and 92.
Correspondingly, rectangular holes 96 and 97 are provided so that a corresponding display on the upper surface of the casing 90 can be visually observed.

After the leading edge of the color photographic paper 2-8 has passed, the lever 94 is retracted from the conveyance path of the color photographic paper 28. It should be noted that if the operating force of the lever 94 is weakened 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, there is no need to retract the lever 94.

Furthermore, in this embodiment, the bunch 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 the bunch hole 62 may be punched in 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.
