In addition to U, a program memory, a clock oscillator and a counter are built in, a power supply battery 34 is loaded, and power is supplied from a booster circuit incorporated in the circuit board 30 (the manufacturing year recorded in the IC memory 15). From the same day as the month), count the number of clock pulses with a counter. The recording control IC 38 further receives an ON signal of the synchro switch 33 and a signal indicating whether or not stroboscopic photography has been performed. The photo sensor 39 has a light emitting portion and a light receiving portion, detects whether or not the high reflection plate is positioned in front of it, and inputs the detection signal to the recording control IC 38.

On the front surface of the case of the recording control IC 38, DP
A connector 43 is provided as an interface terminal for recording and reading various data from the outside of the lens-fitted photo film unit in the IC memory 15 through the recording control IC 38 at an E dealer, a photo lab or the like. The data recorded in the IC memory 15 at the DPE dealer includes a code indicating that it has been used in the LF, a store code, an order date, and the like. At the photo lab, the data such as the order date, photo lab code, LF type data, and serial number data are input to the IC memory 15. In addition, the IC memory 15
In addition to this, the number of prints, a logo, and the like can be used as the data to be recorded in.

A personal computer 60 as shown in FIG. 1 is prepared at a camera shop, a DPE dealer, a photo lab, or the like. A dedicated expansion board to which a cord 61 and a plug 62 are connected is attached to the expansion slot of the personal computer 60.
After the paper box is peeled from the loaded lens-fitted film unit, the plug 62 is inserted into the connector 43 exposed on the front surface of the unit body 18. And personal computer 60
After operating the keyboard 63 of the above to display the above data on the CRT 64 of the personal computer 60 and then performing the transfer operation,
The data is written in the IC memory 15 of the memory substrate 16 via the code 61, the plug 62, the connector 43, the recording control IC 38, the flexible wiring board 40, and further via the connector, the metal contact piece, the connection pin, and the contact pattern 17 described later. Be done. Although the size of the unit main body 18 is actually much smaller than that of the personal computer 60, the unit main body 18 and the personal computer 60 are drawn in substantially the same size in FIG. 1 for the sake of clarity.

At the tip of the flexible wiring board 40 is provided a plug 41 in which a plurality of connection pins 41a are arranged in a line. The plug 41, as shown in FIG.
0 is connected to the connector 42 incorporated in the upper part of the cartridge chamber 26. A sleeve for bearing the winding shaft 28a of the winding dial 28 is provided on the upper wall of the cartridge chamber 26, and a plurality of elastic and conductive metal contact pieces 45 are radially assembled on the outer circumference of the sleeve. . One end of each metal contact piece 45 is soldered to a pin of the connector 42 via a lead wire.

The other end of the metal contact piece 45 is pressed against the head of a connecting pin 46 arranged so as to surround the winding shaft 28a, and presses each connecting pin 46 into the cartridge chamber. Therefore, when the photographic film cartridge 2 is loaded in the cartridge chamber 26, the connection pin 46 exposes the contact pattern 17 on the upper surface of the cartridge body 5.
Touch the predetermined position of. This electrically connects the IC memory 15 and the recording control IC 38.

Unlike the conventional 135 film cartridge, the photographic film cartridge 2 needs to externally drive the light shielding lid 9 in addition to the drive of the spool 7. Therefore, when loaded in a camera or a film unit with a lens, it is necessary to properly engage an external driving member with both the key groove 7a and the key groove 9a. For this reason, the cartridge body 5 itself is floated in the cartridge chamber 26, the cartridge body 5 is positioned at both ends of the spool 7, and a shell float that gives the cartridge body 5 a degree of freedom in the rotation direction around the spool 7 is used. It is held in a so-called system. By holding the cartridge main body 5 in the cartridge chamber 26 by this shell float system, it becomes easy to engage the opening / closing member of the light shielding lid 9 with the key groove 9a of the light shielding lid 9.

When the loading position of the cartridge main body 5 is determined by the shell float method, if the contact pattern 17 of the memory substrate is provided at a position surrounding the key groove 7a of the spool 7 as described above, each of the connection pins 46 is provided. The contact between the contact pattern 17 and the contact pattern 17 can be maintained in good condition, and the cartridge body 5 can be freely rotated when the key groove 9a and the opening / closing member of the light shielding groove 9 are engaged. Of course, since the amount of rotation at this time is a small amount within the error range, the connecting pin 46 will not be erroneously connected to another portion of the contact pattern 17.

The front cover 23 is assembled so as to cover the front surface of the body base 20. On the front surface of the front cover 23, in addition to an opening for exposing the taking lens and the stroboscopic light emitting section 31 to the front surface, an opening 47 for exposing the connector 43 of the recording control IC 38, and an objective window 4 for defining the view range of the finder system.
8 are formed. The aspect ratio of the objective window 48 is 9:16, which is the same as that of the high-definition TV screen, and this aspect ratio is the standard aspect ratio of the photographic film 6.

A mask plate 49 is slidably incorporated behind the objective window 48. When the mask plate 49 is inserted behind the objective window 48 by operating the knob 50, the viewfinder visual field range is limited to a panoramic range having an aspect ratio of about 1: 2.8. When the mask plate 49 is moved to this position, the signal plate 51 integrated with the mask plate 49 is located in front of the photo sensor 39. Since a highly reflective material is provided on the back surface of the signal plate 51, the mask plate 49 is set at either the standard position or the panoramic position by monitoring the output of the photo sensor 39 at the moment when the synchro switch 33 is turned on. It is possible to identify whether or not the image has been captured. If another visual field range switching mechanism is used instead of the mask plate 49,
In addition to the standard visual field range and the panoramic visual field range, a conventional visual field range corresponding to the aspect ratio of the L print size may be added. Also in this case, the setting position of the switching operation member is electrically or photoelectrically set at the time of photographing. It is possible to detect and identify the selected visual field range.

A shutter button 53 is provided on the upper surface of the front cover 23.
Are provided integrally. When the shutter button 53 is pressed after the completion of the shutter charge, the shutter mechanism incorporated in the exposure unit 21 is activated to take an image. The rear cover 24 covers the back surface and the bottom surface of the body base 20 in a light-tight manner. Bottom cover 54 that covers the bottom surface of the cartridge chamber 26
A boss 55 is projectingly provided on the cartridge, and as shown in FIG. 4, the lower end of the spool 7 is supported to hold the cartridge body 5 in a shell float system.

The unit main body 18 manufactured in this manner is covered with a paper box (not shown) having openings for exposing the photographing lens, shutter button, etc., to complete the lens-fitted film unit. This paper box covers the opening 47,
The connector 43 is invisible to the user.

This lens-fitted film unit is purchased by a general user and used for photographing. When the shooting operation is performed, the synchro switch 33 is turned on once for each shooting regardless of whether or not the flash shooting is performed. When this ON signal is input to the recording control IC 38, the recording control IC 3
Reference numeral 8 identifies whether or not stroboscopic photography has been performed and whether the viewfinder system is set to the standard visual field range or the panoramic visual field range. The presence or absence of stroboscopic photography can be electrically identified by whether or not the main capacitor 32 is discharged, and the set position of the visual field range can be identified by the output of the photo sensor 39.

The recording control IC 38 uses, as exposure data, strobe data representing whether or not stroboscopic photography has been performed.
Further, the identification information of the viewfinder field range is recorded in the IC memory 15 as print format data for each frame, and the data of the number of clock pulses counted by the counter in the recording control IC 38 is also recorded in the IC memory for each frame. Record at 15.

The used lens-fitted film unit is taken out by the user to a DPE dealer as it is. At the DPE dealer, the paper box is peeled off from the lens-fitted film unit for which a print request was received. As a result, the connector 43 is exposed on the front surface of the unit main body 18 through the opening 47. Therefore, as shown in FIG. 1, the plug 62 of the cord 61 connected to the personal computer 60 is inserted into the connector 43. Then, by operating the keyboard 63 of the personal computer 60, data such as a code, a store code, an order date, an underwriting number, etc. indicating that the lens-fitted film unit has been used, the plug 62, the connector 43, the recording control IC 38, and the flexible wiring. Writing is performed on the IC memory 15 of the memory substrate 16 via the plate 40, the plug 41, the connector 42, the metal contact piece 45, the connection pin 46, and the contact pattern 17.

At the photo lab, the DP 43 is attached to the connector 43 of the lens-fitted film unit sent from the DPE dealer.
As with the E dealers, plug in the personal computer, write the order date, the laboratory code, the LF type data, the serial number data, etc. in the IC memory 15, and
The data written in the IC memory 15 at the PE handling shop is read and used as a guide for development and print processing, and is also used for subsequent delivery processing.

After the data input to the IC memory 15 is completed,
The photographic film cartridge 2 is taken out from the lens-fitted film unit, but before that, the winding dial 28 is rotated to wind all the photographic films 6 into the cartridge body 5, and then the light-shielding lid 9 is closed using a dedicated jig. . In order to make the work of closing the light shielding lid 9 efficient,
In conjunction with the opening operation of the bottom lid 61 when taking out the photographic film cartridge 2 from the lens-fitted film unit,
It is also possible to incorporate in the lens-fitted film unit a structure for automatically closing the light-shielding lid 9.

The photographic film cartridge 2 thus taken out is set in a magnetic recording device (not shown). This magnetic recording device electrically reads the data recorded in the IC memory 15 and performs a data transfer process of recording the data in the magnetic recording layer provided in the photographic film 6. The data format at the time of this data transfer processing is based on the binarized recording method as described in, for example, Japanese Patent Application Laid-Open No. 7-219021.

As the data read from the IC memory 15 in this data transfer processing, the LF identification data and the manufacturing date data recorded as basic data at the manufacturer stage and the strobe recorded at each user frame at the user stage. There are data, print format data, clock pulse count data counted by a counter, and the like.
In particular, date data representing the shooting date is calculated for each shooting frame from the manufacturing date data and the number of clock pulses recorded for each shooting frame. Magnetically recorded on the recording layer.

The photographic film cartridge 2 which has completed the data transfer process is sent to the film developing process and the printing process. The cartridge body 5 and the photographic film 6 are separated when the film is developed, but since the ID number recorded in the latent image on the photographic film 6 is revealed, this is attached to the cartridge body 5. If the ID number of the code label 12 is collated, the correspondence will not be confused. Therefore, when a system is adopted in which the developed photographic film 6 is reloaded in the cartridge body 5 and returned to the user, the photographic film 6 is separated from the cartridge body 5 at the time of film development, and thereafter, a DPE dealer. Until the product is delivered, the print processing can be performed by handling only the photographic film 6.

In the printing process, the photographic film 6 is used.
Since the data required for the magnetic recording layer has already been recorded, the cartridge main body 5 to which the IC memory 15 is attached is not required. The photographic film 6 separated from the cartridge body 5 is sequentially applied to the printer, and the print processing is executed from the leading end side of the photographic film 6 for each frame. Since shooting data corresponding to each frame is magnetically recorded in each shooting frame, the printer reads the data to determine whether exposure correction is necessary or performs appropriate exposure correction to perform proper printing. be able to.

For example, when the LF identification data is read from the magnetic recording layer, the exposure correction width at the time of print exposure is set to be wider, or when the strobe data indicating that the stroboscopic photography is performed is read, the central portion of the screen is read. By performing a correction such that the subject (often, a person) has a proper exposure, it is possible to perform printing in consideration of the shooting characteristics of the lens-fitted film unit.

When the read print format data indicates that the panorama is designated, the print magnification, the negative mask, and the photographic paper mask are automatically switched for the panoramic print, and the print processing is made efficient. As a result, it is not necessary to incorporate a mask mechanism for regulating the exposure range of the photographic film 6 into the lens-fitted film unit, which contributes to cost reduction of the lens-fitted film unit. Furthermore,
By operating the date imprinting device attached to the printer according to the date data read from the magnetic recording layer, the date of photography can be overprinted on the print photograph at an appropriate position, posture, size and color. it can.

When the processing at the developing place is completed, the developed photographic film 6 is reloaded into the original cartridge body 5 as it is long and returned to the user via the DPE dealer together with the print photograph. If the exposure correction data and the like obtained at the time of the first simultaneous printing are recorded on another portion of the magnetic recording layer of the photographic film 6, for example, on the film edge on the side where the perforations 6b are formed, it is possible to perform additional printing. This data can also be read and used.

In the embodiment described above, the IC memory for recording various data is provided in the photographic film cartridge, but the IC memory may be provided in the lens-fitted film unit. In this case, as shown in FIG. 5, for example, the IC memory 15 is provided on the circuit board 30, and the recording control IC 3
The recording control IC 38 may be provided in close proximity to the recording control IC 38. This eliminates the need for the flexible wiring board 40 and the plug 41, which can contribute to further cost reduction of the lens-fitted film unit.

In this case, after the photographing is completed, the IC of the film unit with the lens is installed at the DPE dealer or the developing place.
The data is read from the memory 15 and taken out from the unit main body, and magnetically recorded on the magnetic recording layer of the photo film of the photo film cartridge, or the photo film cartridge with the IC memory is used to read from the IC memory 15 of the film unit with lens. The data is read out and transferred to the IC memory of the photographic film cartridge taken out from the unit main body. As a result, the unit main body becomes unnecessary in the subsequent print processing. The IC memory 15 is not limited to being provided on the circuit board 30, but may be provided on the back surface of the front cover, for example, and may be connected to the circuit board 30 by a code line.

Although the connector for exchanging data with the personal computer is hidden by the paper box, an opening may be provided in the paper box and the connector may be exposed through this opening. As a result, data can be input / output without peeling off the outer casing from the unit body, and the camera dealer or the user can add or rewrite data. At a camera store, for example, some option data (for example, store name, cumulative number of sales of the same model, etc.) are prepared in advance, and a selection from these data can be recorded in the IC memory 15. Further, the user can record arbitrary data in the IC memory 15 during shooting by using a personal computer or an electronic notebook.

Further, when the IC memory is provided in the photographic film cartridge, the IC memory is mounted on the peripheral surface side of the cartridge body in the above embodiment, but as shown in FIG. For example, a donut-shaped IC memory 70 may be provided below the contact pattern 17 provided so as to surround the contact pattern 17. In this case, the memory substrate 16 is unnecessary, which is advantageous in terms of mounting space and cost. The IC memory 70 is
For example, it may be fan-shaped.

In the above embodiment, the lens-fitted photo film unit is preliminarily loaded with the photo film.
A general camera with a replaceable film may be used. In this case, an IC provided on the camera body or the photographic film cartridge is provided with a connector or an infrared port on the outer wall of the camera.
Input / output data from a personal computer to the memory. This allows a user having a personal computer or the like or a DPE dealer to input desired data into the IC memory even during shooting. As such data, for example, by inputting personal data of the whole family, for example, birthday, a title such as "HAPPY BIRTHDAY MASAKO" can be burned on the frames photographed on that birthday.
