Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the detection of the type of attached enlargement lens in a photographic processor.

[0002]

2. Description of the Related Art As is well known, in a photographic processing apparatus (photographic printing apparatus), it is possible to mount a stretching lens having various focal lengths (stretching magnifications) according to a film (negative) size and a print size. is there.

As a method of automatically identifying the type of the enlargement lens mounted in the photo processing apparatus,
Conventionally, for example, a code (a black-and-white reflection pattern or a hole for transmitting light) for specifying the type of the expansion lens is provided in the case of the expansion lens, and the code can be read using a plurality of photosensors. Has been done. If the number of arrayed photosensors is 7, for example, 128 types of enlargement lenses can be identified as a 7-bit binary code by high or low (1 or 0) of the output of each photosensor.

In the conventional photographic processing apparatus, the lens data of all the enlargement lenses usable in the photographic processing apparatus are registered in the ROM or the like from the shipping stage, and the read binary code is used to read the ROM or the like. The data of the enlargement lens is read from, and the exposure time is adjusted and the color balance is corrected based on the read data.

[0005]

Conventionally, a large number of types of photographic processing apparatuses, such as those having different specifications or improved specifications, have been supplied to the market. Plural kinds of enlargement lenses such as a zoom lens and a single focus lens having different focal lengths are supplied to each of these photographic processing apparatuses. Further, the enlargement lens is also replaced by an improved product and supplied. Therefore, many kinds of enlargement lenses are supplied to the market,
It is currently used in developing laboratories and DPE shops.

The applicant has adopted a so-called latest version compatible policy in which all the lenses sold in the past can be used in the latest photographic processing apparatus currently sold. However, in recent years, the cumulative number of types of enlargement lenses is a number that can be identified by a photosensor (for example, 1 above).
(28 types) and will overflow soon. In the future, the number of types of enlargement lenses will continue to increase.

In order to deal with this, it is technically possible to deal with the problem by increasing the number of photosensors arranged. For example, if the number of photosensors is 8 and the conventional 7
8 if a bit enlargement lens is attached
The photo sensor of the bit may be configured to always output "0". However, an increase in the number of arrays of photosensors and an increase in lens data to be registered require a design change of sensor parts and an increase in memory capacity, which leads to an increase in cost of the photo processing apparatus. On the other hand, from the user's point of view, the data regarding the enlargement lens which he does not own is unnecessary, and the increase in the cost of the photographic processing apparatus cannot be accepted due to the unnecessary data.

The present invention has been made in order to solve the above-mentioned problems of the conventional example, and the user desires it without increasing the number of photosensor arrays or the memory capacity such as ROM of the conventional photoprocessing apparatus. An object of the present invention is to provide a photographic processing device capable of automatically identifying all enlargement lenses (including new enlargement lenses to be sold in the future).

[0009]

In order to achieve the above object, the photographic processing apparatus of the present invention can select and install any one of a plurality of enlargement lenses, and the attached enlargement lens can be used. In a photographic processing device that can identify the type of lens by reading a code provided on the enlargement lens with a sensor, the code is variable, and the enlargement lens selected by the user can be registered with an arbitrary code. It is characterized by

In the above arrangement, the code may be registered in advance for the enlargement lens group which is frequently used, and the other enlargement lenses may be arbitrarily registered.

Further, the sensor is an array of a plurality of photosensors, and an opening for transmitting light is provided at each position corresponding to each photosensor on the general-purpose stretchable lens mounting substrate, and the opening is appropriately shielded. It is also possible to form an arbitrary cord by closing with.

Alternatively, the sensor is formed by arranging a plurality of mechanical switches, and protrusions for appropriately turning on the switch are attached to respective positions on the general-purpose stretchable lens mounting substrate corresponding to the respective switches. By doing so, an arbitrary code may be formed.

When the lens mounting area 601 of the lens moving deck 600 is at the retracted position (see FIG. 3), the second direction Y− that is adjacent to the lens mounting area 601 and is substantially orthogonal to the first direction XX ′. It is composed of a lens storage deck 700 for storing the zoom lens 500 provided in Y ′.

The lens moving deck 600 is bidirectionally moved in the first direction XX 'between the position shown in FIG. 2 and the position shown in FIG. 3 by a drive mechanism (not shown). In the state shown in FIG. 2, the zoom lens 500 is at the exposure position and the mirror 403 is retracted. Therefore, in this state, by controlling the light source 111, the image on the film can be enlarged and projected on the photosensitive material (printing paper) to expose the photosensitive material. On the other hand, in the state shown in FIG. 3, the zoom lens 500 is retracted onto the lens storage deck 700, and the single focus lens 550 is mounted in the lens mounting area 601. Further, the mirror 403 is at the exposure position, and the light transmitted through the film is reflected by the mirror 403, and the light sensor 4

As is clear from each figure, the zoom lens 5
00 is the lens mounting area 601 of the lens moving deck 600
Also, it is attached to or housed in any one of the lens housing deck 700 and is always located inside the enlarging lens unit 400. On the other hand, as shown in FIG. 5, the single focus lens 550 can be mounted in the lens mounting area 601 of the lens moving deck 600 only when the zoom lens 500 is stored in the lens storage deck 700. In the photographic processing apparatus of this embodiment, the zoom lens 500 is normally used as the enlargement lens, and the single focus lens 550 is used.
Are stored outside the photographic processor.

The enlargement lens unit 400 is shown in FIG.
It is provided inside the housing 120 shown in FIG. The film holder 402 is located below the mirror unit 112. In the present embodiment, since the zoom lens 500 needs to slide in the second direction Y-Y ', the first direction X-X' and the second direction Y-Y 'are each relative to the ground. It is adjusted to be parallel (horizontal). Therefore,
The optical axis of the zoom lens 500 or the single focus lens 550 is perpendicular (vertical) to the ground. In addition, the housing 120 includes a stretching lens unit 40 inside the housing 120.
The door 121 is provided so that the lens mounting area 601 of the 0 lens moving deck 600 faces the retracted position. By opening the door 121, the zoom lens 500 is manually slid in the second direction YY ′ from the lens mounting area 601 of the lens moving deck 600 to the lens storage deck 700, or the single focus lens 550 is attached. It can be mounted in the lens mounting area 601 of the lens moving deck 600.

Generally, the size of the film to be printed is overwhelmingly 135 size film and APS film, and standard shooting and panoramic shooting, as well as APS
In the case of a film, there may be a mixture of high-definition images, so the zoom lens 500 is mounted as an enlargement lens of the photographic processing apparatus 1 shown in FIG. In this way, by making the angle of view of the lens changeable,
You can print pictures of more than one size with one lens without changing the enlargement lens.

When a stretching magnification larger than usual is designated or when printing a negative film of a size other than 135, it is necessary to replace the zoom lens 500 with the single focus lens 550. In that case, for example, the operation panel 113 shown in FIG. 1 is operated to drive a drive mechanism (not shown) to move the lens mounting area 601 of the lens moving deck 600 to the retracted position.

Next, the door 121 shown in FIG. 1 is opened, and the handle 520 is manually pushed in the Y direction to move the zoom lens 50.

13 is an arm 615 rotatable about an axis 614.
Is rotatably supported by the arm 615, and the arm 615 is urged in the X'direction by a spring or the like (not shown). In addition, guide portions (for example, concave portions) corresponding to the rollers 611 to 613 are formed on the side surface of the base 510 of the zoom lens 500 (obviously not shown). Guides on the side of the zoom lens 500 and rollers 611-613
By engaging with and, the zoom lens 500 is positioned in the horizontal direction (first direction XX 'and second direction YY'). In addition, in the center of the lens mounting area 601 of the lens moving deck 600, the zoom lens 500
Alternatively, an exposure window 660 for projecting an image on the negative film magnified by the monofocal lens 550 onto a photosensitive material is provided. Further, in the lens mounting area 601 on the lens moving deck 600, two parallel rails 621 and 622 for positioning the zoom lens 500 in the vertical direction.
Are formed in the second direction Y-Y '.

Next, the positioning of the single focus lens 550 in the lens mounting area 601 on the lens moving deck 600 will be described. As shown in FIG. 5, a single focus lens 550
Is composed of a lens barrel portion 551, an expansion lens mounting substrate (hereinafter, simply referred to as a lens substrate) 552 for holding the lens barrel portion 551, and the like. Further, the lens substrate 552 has the first and second engagement holes 553.
And 554, and a guide 55 protruding in a direction parallel to the optical axis.
5, 556, 557 and the like. The first engagement hole 553 is substantially rectangular including an end surface 553a parallel to the guide 555, and the second engagement hole 554 is substantially triangular or trapezoidal including at least two end surfaces 554a and 554b forming a V shape. . Further, the guide 556 is provided with a notch 560 representing a code for specifying the type of the single focus lens 550, at a position facing a sensor 670 described later.

On the other hand, as shown in FIG. 4A, the lens mounting area 601 of the lens moving deck 600 is brought into contact with the back surface of the lens substrate 552 of the single focus lens 550 to position the single focus lens 550 in the vertical direction. A plurality of (for example, three) protrusions 631, 632, and 633 for performing the above are formed. Further, in the lens mounting area 601, the single focus lens 5
Of the three guides of 50, two guides 555 and 55
Two guide grooves 634 and 636 are formed to fit with each other. A recess 635 is formed in a portion of the single focus lens 550 corresponding to the remaining guide 556.
35 is provided with a sensor 670.

In the vicinity of the guide groove 636, permanent magnets 671 and 672 for attracting and holding the guide 557 of the single focus lens 550 when the single focus lens 550 is mounted in the lens mounting area 601 are provided. . Further, the projection 663 is a permanent magnet in order to attract and hold the flange 552 of the single-focus lens 550. Alternatively, the protrusion 66
A magnet may be adhered to the back side of 3. In this case, the lens substrate 552 is formed by pressing a magnetic metal material such as iron.

Further, in the lens mounting area 601, the first
Positioning pins 637 and 638 that engage with the second engagement holes 553 and 554 are formed. The single focus lens 550 includes a guide 555, a guide groove 634, and a guide 55.
6 and the guide groove 635, and the guide 557 and the guide groove 636 are fitted to each other, and the positioning pin 637 and the first engaging hole 5
It is obliquely loaded in the Y direction from the front in FIG. 4A so that the 53 and the positioning pin 638 and the second engagement hole 554 are engaged with each other. At this time, the guides 555 to 557 are arranged so as not to interfere with the bottom surface of the lens mounting area 601, as shown in FIG.
Hatched areas 641, 642 and 6 of (a)
43 is a slope. Second direction Y of single focus lens 550
The positioning of −Y ′ is performed by bringing the positioning pin 637 into contact with the end surface 553a of the first engagement hole 553.
Further, the positioning of the single-focus lens 550 in the first direction XX ′ is performed by setting the positioning pin 638 to the V of the second engagement hole 554.
It is performed by abutting on both of the two end faces 554a and 554b forming the letter.

As is apparent from FIG. 4B, the tips of the pins 637 and 638 for positioning the single focus lens 550 are formed to be lower than the rails 621 and 622. The positioning pins 637 and 6 of the base 510 of the zoom lens 500 are arranged so that the zoom lens 500 and the positioning pins 637 and 638 do not interfere with each other.
It goes without saying that a notch is formed at a position corresponding to 38.

Similarly, in the lens mounting area 601 of the lens moving deck 600, the guide grooves 634 to 636 are formed inside the rails 621 and 622, respectively.
Correspondingly, the width of the lens substrate 552 of the single focus lens 550 is also formed to be shorter than the distance between the rails 621 and 622. Therefore, the single focus lens 5
50 is a lens mounting area 601 of the lens moving deck 600
When mounted on, the single focus lens 550 does not interfere with the rails 621 and 622.

Next, the type identification of the enlargement lens, particularly the single focus lens 550, in this embodiment will be described. The sensor 670 is for detecting that the single-focus lens 550 is mounted in the lens mounting area 601, and is an optical sensor including, for example, a light emitting element 670a and a light receiving element 670b (see FIG. 6B. )), Photosensors each including a light-emitting element 670a and a light-receiving element 670b are arranged in parallel, for example, in a direction perpendicular to the 7-sheet surface.

As shown in FIGS. 6A and 6B, when the single focus lens 550 is mounted in the lens mounting area 601, the guide 556 of the single focus lens 550 is guided by the sensor 67.
It is interposed between the light emitting element 670a of 0 and the light receiving element 670b. As described above, since the notch 560 is appropriately formed in the guide 556 at a position facing the seven light emitting elements 670a, the light receiving element 670b facing the notch 560 receives light from the light emitting element 670a. Incident. On the other hand, the light from the light emitting element 670a is blocked and the light does not enter the light receiving element 670b facing the portion where the notch 560 is not formed. In this way, the seven light receiving elements 670b each output a high level signal or a low level signal.
A combination of 0b output signals makes it possible to identify 7 types of enlargement lens types, that is, 128 types of enlargement lenses. In addition, the notch 5 formed in the guide 556
60 represents a substantially 7-bit binary code.

As is apparent from FIG. 6B, the sensor 6
70 is a recess 635 formed in the lens moving deck 600.
Since the sensor 670 does not spatially interfere with the zoom lens 500, that is, the sensor 670 is positioned below the bottom surface of the zoom lens 500, between the lens mounting area 601 of the lens moving deck 600 and the lens storage deck 700. It does not hinder the movement of the zoom lens 500. Further, when neither the zoom lens 500 nor the single focus lens 550 is mounted in the lens mounting area 601, or when the zoom lens 500 is mounted, the light from the light emitting element 670a of the sensor 670 is received without being blocked. Element 6
Since it is incident on 70b, it is not erroneously determined that the single focus lens 550 is attached.

Next, a procedure for registering the enlargement lens selected by the user with an arbitrary code will be described.

It has been nearly 40 years since the present applicant commercialized the first photographic processing apparatus,
During that time, many types of enlargement lenses have been developed. Conventionally, the first enlargement lens that can automatically identify the type of enlargement lens is given a code of "1" in decimal system and "0000001" in binary system, and the code numbers are increased one by one. Then, the 128th enlargement lens has "128" in the decimal system and "111" in the binary system.
It has been set so as to give a code of 1111 ". In this method, there is a problem that there is no code to give to the 129th lens and thereafter.

On the other hand, the object of the present invention is to deal with the 129th and later newly developed enlargement lenses without increasing the number of bits of the sensor 670. For that reason, firstly, for the 129th lens and thereafter, 10
The code number is increased one by one in order from "1" in the base system and "0000001" in the base system, and the code numbers are given in duplicate. Secondly, instead of registering (storing) the data of all the enlargement lenses in the memory etc. of the photo processing device 1,
A predetermined number (for example, 60) of expanding lenses (for example, relatively new products) predicted to be frequently used are picked up, and only those data are registered in advance. If the code is duplicated, register new product data.

When the enlargement lens desired by the user is not registered, the operation panel 113 is used to
By inputting the code number described in the enlargement lens, the data concerning the enlargement lens stored in the floppy disk, the CD-ROM or the like is transferred to the memory of the photographic processing apparatus 1.

Generally, a user who newly purchases the photographic processing apparatus according to the present invention can obtain only the enlargement lens to be released thereafter and a relatively new product in the market at the time of purchase, so that the old product can be used. There is no particular confusion if the code for the latest code and the code for the latest product are duplicated.

On the other hand, when a user who has been using the photo processing apparatus for a long time purchases the photo processing apparatus according to the present invention,
Most likely you have an older stretch lens with duplicate code. In that case, change the code number of the old enlargement lens and register it.
Specifically, the lens substrate 552 originally attached to the stretching lens 550 is removed and replaced with a general-purpose lens substrate 552 '. Then, any one of the code numbers not registered in the photo processing apparatus 1 is selected and the binary code of the general-purpose lens substrate 552 'is set so as to correspond to the code number.

A general-purpose lens substrate 552 'is shown in FIG. As is apparent from the figure, the guide 556 of the general-purpose lens substrate 552 'has a plurality of openings 558 formed therein. Each opening 558 is formed by the light emitting element 67 in the sensor 670 described above.
0a and the light receiving element 670b are formed so as to be orthogonal to the optical path of each photo sensor, and in that state, light from all the light emitting elements 670a is made incident on all the light receiving elements 670b. In the present embodiment, the opening 558 of the general-purpose lens substrate 552 'is appropriately closed by, for example, a black resin light-shielding cap 560, so that the user can set an arbitrary code number.

The cap 560 may be configured such that the user inserts it into the opening 558 of the general-purpose lens substrate 552 'one by one, or the opening 558 may be formed in a groove shape and the slide type cap 560 is fitted in advance. You can leave it. Alternatively, the opening 580 may be easily closed with an adhesive tape.

Next, the procedure for registering the enlargement lens that the user desires to use will be described. First, the operation panel 113 is operated to display the “lens number registration” menu screen shown in FIG. 8 on the monitor display device 114. In FIG. 8, the numeral 901 on the left end represents the number in the lens number registration frame, which is 1 by the scroll key operation.
Up to 128 registered frames, any 10 continuous frames are displayed. The "lens number" 902 in the center is
For example, of the product number (model number) of each enlargement lens,
The last 4 digits are displayed. When the user registers, he / she inputs using the ten keys. The "setting code" 903 on the right end is a 7-bit binary code assigned to each enlargement lens displayed in black and white dots, and is conventionally uniquely set for the serial number of the enlargement lens. It is a thing. In the present embodiment, regarding the enlargement lens that is registered in advance at the time of shipment from the manufacturer, the binary code assigned to the enlargement lens is preferentially registered. Of the lenses arbitrarily selected by the user, for those lenses whose binary codes do not overlap, the binary code of the enlargement lens is automatically registered. Also, if the binary code of the lens selected by the user is duplicated with the one already registered,
The user arbitrarily selects and inputs the binary code from unregistered binary codes. The last 4 digits and the binary code of the input product number of the enlargement lens are displayed in the area 904 at the bottom of the screen. As an example of the binary code input, for example, the dots are sequentially blinked from the left end of the screen, and "Y" is input for whitening and "N" for blackening. In addition, the cap 5 of the general-purpose lens substrate 552 '.
It goes without saying that the position of 60 is made to coincide with the position of the black dot of the binary code selected by the user.

When the user selects the enlargement lens, the storage medium (C which stores data on all the enlargement lenses usable in the photographic processing apparatus 1).
D-ROM or the like) is loaded into the reading device 122. A control circuit (not shown) reads out data regarding a newly registered enlargement lens using the operation panel 113, for example, a focal length (shooting magnification), an open aperture value of the lens, a color balance, etc. from a recording medium, a memory, etc. Transfer to.
This completes the registration of the enlargement lens by the user. When the sensor 670 detects that the newly registered enlargement lens is mounted, the control circuit reads the data stored in the memory or the like and corrects the exposure time, the color balance, or the like based on the data. .

As described above, for example, lenses 1 to 60, which are expected to be frequently used, are registered in advance at the time of shipment from the manufacturer so that the user can arbitrarily register the empty frames 61 to 128. It may be configured to.
Alternatively, leave all empty frames at the time of manufacturer shipment, 1
The user may register in order from.

Further, although the optical sensor is used as the sensor 670 in the above embodiment, the invention is not limited to this, and a mechanical sensor such as a limit switch may be used. In that case, a projection member for turning on / off the mechanical sensor may be attached to the general-purpose lens substrate 552 ′ instead of the cap 560. In addition, the sensor 670
The position of is not limited to the inside of the concave portion 653 of the lens moving deck 600, and may be any position as long as the movement of the zoom lens 500 is not hindered and the mounting of the zoom lens 500 is not detected.

[0049]

As described above, in the photographic processing apparatus of the present invention, any one of the enlargement lenses can be selected and attached from a plurality of types of enlargement lenses, and the type of the attached enlargement lens is In the photographic processing device that can be identified by reading the code provided on the enlargement lens with a sensor, the code is variable and the enlargement lens selected by the user can be registered as an arbitrary code. If the number of codes exceeds the number of codes that can be read by the sensor, the same code can be assigned to multiple types of enlargement lenses, and if one code is duplicated, one of the codes can be changed. The existing system can be used as is without changing the code system or the code system. It is possible to prevent the cost of the physical device. In addition, since it is practically rare for the user to own all of the enlargement lenses that can be identified by the sensor, the same code is assigned to multiple types of enlargement lenses, and if the codes are duplicated, either It can be configured to change the code in.

In addition, the code of the expanding lens group which is frequently used is registered as the code in advance,
By configuring the other enlargement lenses so that they can be arbitrarily registered, a user who does not use a special enlargement lens can immediately use the photo processing device without performing the enlargement lens registration work. It will be possible.
