However, IX2
The print service provided by imprinting an optical mark on a 40-type photo film is limited to the creation of three types of print photos as described above. For this reason, it is conceivable to provide a magnetic recording device as described above in order to realize various print services with the lens-fitted film unit. However, the magnetic recording device is expensive and is characterized by low cost. The unit was not really possible. You can also change the size of the exposure area,
Although a switching mechanism for enabling close-up photography is relatively inexpensive, it is difficult to incorporate a more complicated switching mechanism, for example, a mechanism for switching between imaging lenses having different focal lengths.

Further, as described above, a film unit with a lens having a long-focal length photographing lens and capable of performing telephoto photographing does not impair the portability by bending the optical path. It is larger than a film unit with a lens and is not portable. Further, the incorporation of an optical system for bending the optical path has caused an increase in manufacturing cost.

On the other hand, when print production is requested at the same time as development, it is possible to instruct various types of printing conditions to the developing laboratory, but it is troublesome since appropriate instructions must be given. Further, in a photo lab, the printing process must be set in accordance with the printing conditions instructed for each photo film or each photographed frame, which complicates the work.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a film unit with a lens which can suppress a rise in manufacturing cost and can receive various print services with a simple configuration.

As shown in FIG. 1, each photographing frame of the IX240 type photographic film 18 has an exposure range 18a defined by an aperture 21c and a perforation 35 for film feeding at one outer edge of the exposure range 18a. The optical mark area 37 is provided on the other edge. The optical mark area 37 includes a panoramic print photograph (89 × 254 mm) having a different aspect ratio, in addition to an H-size standard print photograph (89 × 158 mm).
This is a well-known area for optically imprinting a print condition designation mark 38 represented by a PAR bit (Print Aspect Ratio) for designating creation of a C-size print photograph (89 × 127 mm).

The range of the optical mark area 37, the size and interval of the bits forming the print condition designation mark 38, and the like are determined by the APS format. Conventionally, the number of bits constituting the print condition designation mark 38 imprinted on the optical mark area 37 has been used as a maximum of two of the first bit 38a and the second bit 38b. 3 bits 38c is 1
One can add up to three images.

The photographic printer performs printing by identifying the printing conditions based on the number of bits constituting the printing condition designation mark 38 imprinted on the optical mark area 37 at the time of printing. As for the size of each bit, the interval between each bit, and the size of the optical mark area 37 on which all the bits are imprinted, the third bit 38c is added as specified in the APS format. It is not necessary to make a significant change on the photographic printer side that reads 38, as long as the change is made on the program.

The print condition designation mark 38 to be imprinted for each photographing frame includes a first bit 38a and a second bit 38b.
And the third bit 38c. For example, the first bit 38a and the second bit 38b are imprinted,
When the print condition designation mark 38 has 2 bits, the print conditions are determined so that the C size print range 41 is trimmed from the exposure range 18a to create a C size print photograph.

Similarly, when only the first bit 38a is imprinted and the print condition designation mark 38 is 1 bit, the P size print range 42 is trimmed from the exposure range 18a and the P size print range is trimmed. If a photo is created and none of the bits are imprinted and the print condition designation mark 38 is 0 bit,
The printing conditions are determined so that an H-size print photograph (standard print photograph) is created with the entire screen of the exposure range 18a as the print range 43.

In addition to such well-known print condition designation, the third bit 38c added in the present embodiment
From the first bit 38a to the third bit 38c
If all the bits are imprinted, the exposure range 18

When the field switching plate 44 is rotated so that the 1.6x telephoto field frame 53 is located in front of the viewfinder 5, the C size field frame 51 is moved downwardly outside the outer peripheral surface of the lens-fitted film unit 2. The front panel 42 and the lower part of the front cover main body 41 are provided with slits (not shown) for retreating the field frame switching plate 44 so that they can escape.

In the film unit with a lens according to the present embodiment, as described above, the photographing lens 4 having a focal length of 24 mm
Is used to convert the image exposed to the entire exposure range 18a into H
The standard mode is a case where the image is enlarged to a print photograph of a size. The objective side window 6 serving as a standard field frame regulates the field of view of the finder 5 so that the photographing range printed in the standard mode is observed by the finder 5. . Therefore, when the notch 54 faces the objective side window 6, the field of view of the finder 5 is set to a range corresponding to the standard mode, that is, the entire range of the exposure range 18a is exposed by the imaging lens 4 having a focal length of 24 mm. The range is a standard visual field range in which the range can be observed.

The viewing range. Then, in the 1.6 times telephoto field range, a photographing range corresponding to the case of using a photographing lens having a focal length of 38.4 mm is observed.

On the outer periphery of the opening 44a of the visual field switching plate 44,
A cam groove 44c having a predetermined shape in which the distance from the center of the opening 44a is changed is formed. This cam groove 44c
One end 56a of a rotation lever 56 rotatably attached to the main body base 21 is inserted into the main body 21. Rotating lever 56
5, is pivotally supported by a pin 21e protruding from the upper surface of the light-shielding cylinder 21d of the main body base 21. One end 56a of the rotating lever 56 is connected to the finder 5 of the exposure unit 22.
Through the finder opening 43 of the front cover body 41.
Is inserted into the cam groove 44c of the visual field switching plate 44 through the notch 43a (see FIG. 4) formed in succession. Thus, when the field switching plate 44 rotates, the rotation lever 56 rotates about the pin 21e according to the shape of the cam groove 44c.

A concave portion 57 is formed below the light-shielding cylinder 21d along the film winding direction.
The print condition designation mark 38 has a photo film 18 inside.
First, second and third openings 58a, 58 for imprinting on the
b, 58c are formed. In the recess 57,
A mark switching plate 61 formed of a light-shielding thin plastic and having openings 61a for opening the openings 58a, 58b, 58c at specific sliding positions is arranged so as to be slidable in the left-right direction. You. A pin 62a formed at one end of the slide lever 62 is engaged with a hole 61b formed at an end of the mark switching plate 61.

On the front side of the mark switching plate 61, an imprinting light guide 63 and a light shielding cover 64 are attached. The slide lever 61 is slidably attached to the front surface of the light-shielding cover 64 in the left-right direction, and is urged rightward in the figure by being hung on one end by a coil spring 66 hung on the light-shielding cover 64. . A fork portion 62b is formed at the other end of the slide lever 62, and the fork portion 62b is engaged with the other end 56b of a rotating lever 56 extended so as to go around the side of the light shielding cylinder 21d. ing. Thereby, the mark switching plate 6
1 is slid in the left-right direction by a slide lever 62 that slides in conjunction with the rotation of the rotation lever 56, and one end 56a of the rotation lever 56 is always placed on the inner wall surface of the cam groove 44c by the bias of the coil spring 66. The rotation of the field switching plate 44 is reliably transmitted to the mark switching plate 61 by the contact.

The light emitted from the imprinting LED 33 mounted on the back side of the printed circuit board 28 passes through the cylindrical portion 64 a of the light shielding cover 64 and the imprinting light guide 6.
3, and is guided by the internal reflection of the light to irradiate light toward each of the openings 58a, 58b, 58c.

The cam groove 44c, the rotating lever 56,
Each opening 58a, 58b, 58c, mark switching plate 61, slide lever 62, light guide 63, light shielding cover 6
4, the coil spring 66 constitutes a mark switching mechanism for changing the printing condition of the print condition designation mark 38 according to the selection by the operation knob 9.

When the operation knob 9 is operated by the mark switching mechanism so that the C size field frame 51 faces the object side window 6, the mark switching plate 61 is moved to the left in FIG.
Withdrawing from the first opening 58a, the opening 61a is set at a position facing the second opening 58b. As a result, the first and second openings 58a and 58b are opened, so that the first bit 38a and the second bit
A 2-bit print condition designation mark 38 consisting of bits 38b is imprinted. Next, when the operation knob 9 is operated so that the P size field frame 52 faces the objective side window 6,
The mark switching plate 61 is moved rightward in FIG.
Are set at a position facing the first opening 58a and closing the second opening 58b. As a result, the 1-bit print condition designation mark 38 of only the first bit 38a is imprinted on the optical mark area 37.

Next, when the operation knob 9 is operated so that the 1.6x telephoto field frame 53 faces the object side window 6, the mark switching plate 61 is slid to the leftmost in FIG.
1a is set to a position facing the third opening 58c, and is set to a position to open all of the openings 58a, 58b, 58c. As a result, all the bits 38a, 38b, 39c from the first to the third are stored in the optical mark area 37.
The print condition designation mark 38 of 3 bits is printed.

Further, when the operation knob 9 is operated so that the notch 54 faces the object side window 6, the mark switching plate 61 is operated.
Is slid to a position where all the openings 58a, 58b, 58c are closed. As a result, no bit is imprinted on the optical mark area 37, and the print condition designation mark 38 has 0 bit.

The film unit with a lens configured as described above is different from the conventional film unit with a lens in which the print condition designation mark 38 is composed of two bits of a first bit 38a and a second bit 38b as a PAR mark. The print condition that can be designated by adding the third bit 38c is increased. Therefore, it is possible to use a common component member with the conventional film unit with a lens, and it is possible to reduce a change in a manufacturing line and an addition of a manufacturing facility, and suppress an increase in manufacturing cost.

In addition to the PAR mark for designating the print size, the 1.6 × telephoto print condition designation mark 38 is printed, so that the focal length of the photographing lens 4 is about 1.6 times that of 24 mm. It is possible to create a print photograph equivalent to photographing with a photographing lens having a focal length of. For this reason, it is not necessary to lengthen the optical path length from the photographing lens 4 to the photographic film 18, and since a complicated mechanism for switching the photographing lens is not required, the configuration of the film unit with the lens is small and thin without complicating the structure. Can be maintained.

Next, the operation of the above configuration will be described. When taking a picture, first, the wind-up knob 14 is rotated to wind up one frame of the photographic film 18 and charge the shutter. The photographer operates the operation knob 9 to set the standard position (index 16b “H”) and the C-size position (index 16a “C”) according to the type of the subject, the subject distance, and the intended style. , P size position (index 16c
"P"), 1.6x telephoto position (index 16d "1.6")
And select the shooting mode.

By operating the operation knob 9, the field switching plate 44 is rotated, and the field of view of the finder 5 becomes the field of view according to the selected photographing mode. Thus, the finder 5 allows the user to observe the photographing range that is actually used as a print photograph. Viewing range 71 (H size print mode), 72 (C size print mode), 73 (P size print mode), 7 corresponding to each shooting mode
4 (1.6 times telephoto mode) are shown in FIGS.
(A), FIG. 8 (A), and FIG. 9 (A).

Further, by the rotation of the field switching plate 44, the mark switching plate 61 is slid via the rotation lever 56 to a position corresponding to the selected photographing mode. The photographer looks at the viewfinder 5 and performs framing, and then presses the shutter button 10 to perform photographing.

If it is necessary to perform flash photography, the charging operation lever 8 is slid to the ON position, and then the display LED 5 is moved through the display light guide 12.
After confirming the lighting of 8, ie, the completion of charging of the main capacitor 50, the shutter button 10 is pressed.

When the shutter button 10 is pressed, the shutter mechanism is operated, the shutter blades are opened and closed, and photographing is performed. The light transmitted through the taking lens 4 reaches the emulsion surface of the photographic film 18 via the aperture 21c. Thus, the entire exposure range 18a is exposed. When the shutter is opened and closed, the synchro switch 32 is turned on, and the imprinting LED 33 emits light. At this time, if charging of the flash has been completed, flash emission is performed and flash photography is performed.

As described above, the imprinting LED 33
Is emitted toward each of the openings 58a, 58b, 58c via the light guide 63 for imprinting. Since the mark switching plate 61 is set between each of the openings 58a, 58b, 58c and the light guide 63 for imprinting, the LED 33 for imprinting from the opening exposed according to the selected photographing mode. The light is applied to the optical mark area 37 below the exposure area 18a of the photographic film 18.
It is reflected on.

As shown in FIGS. 6 (B), 7 (B), 8 (B), and 9 (B), the exposure screen 18a has a single screen size regardless of the shooting mode. Done. On the other hand, in the print condition designation mark 38 imprinted on the optical mark area 37, a bit is imprinted in accordance with each shooting mode. Note that H shown in FIG.
Bits are not imprinted if the size is specified.

In this way, the photographing is performed while selecting the photographing mode for each photographing, and after the photographing of all the photographed frames is completed, the film unit with the lens is submitted to the developing laboratory or the DPE shop. At a photo lab or the like, the taken out photo film 18 is subjected to a development process and then set on a photo printer. In the photo printer, the print condition designation mark 3 in the optical mark area 37
8 based on the print processing.

FIGS. 6, 7, 8, and 9 show print ranges and print examples in which the print range is enlarged and processed under each print condition printed in this manner. The print range 43 when the H size mode is designated is the same as the exposure range 18a, and this print range 43 corresponds to the finder field 71. The print example 81 is printed on H-size photographic paper, as shown in FIG. Further, the print range 41 when the C size mode is designated shown in FIG. 7 is a portion corresponding to the finder visual field 72 in the exposure range 18a, and this print range 41 is enlarged at the same enlargement factor as the H size.
As in a print example 82 shown in FIG. 7C, the image is printed on a C-size photographic paper.

The print range 43 when the P size print mode is designated shown in FIG. 8 is a portion corresponding to the finder field 73 in the exposure range 30, and this print range 43 is enlarged such that the print range 43 is printed on P size print paper. And is printed on a P-size photographic paper as in a print example 83 shown in FIG. 8C.

The print range 44 when the 1.6 × telephoto mode is designated as shown in FIG. 9 is a portion corresponding to the viewfinder field 74 in the exposure range 18a.
The image is enlarged at the same enlargement ratio as the size print, and FIG.
As in a print example 84 shown in (C), printing is performed on H-size photographic paper.

In the above embodiment, as the printing condition assigned to the printing condition designation mark, in addition to the conventional PAR mark, a printing condition for performing pseudo telephoto printing is assigned to the added bit mark. However, the print condition assigned to the print condition designation mark is not limited to the above-described print condition, and in addition to the pseudo-telephoto print designation, for example, printing may be performed in a sepia tone, or all may be assigned as the pseudo-telephoto designation. In this case, it is necessary to set the print conditions assigned to the print condition designation marks in the photo printer in advance.
