In FIG. 12A, a spool gear 73, which will be described in detail later, is provided on the upper portion of the main body 10, and is integrally formed with the spool shaft 33 to rotate. A pulse generating printed circuit board 41 as shown in FIG. 12C is fixed to the upper portion of the main body 10, and the tip of the contact piece 42 fixed to the lower portion of the spool gear 73 is brought into contact with the pattern of the pulse generating printed circuit board 41. ing. S _U is a pattern of the switch at the reference position, and outputs the same signal as S _D through the OR circuit as shown in the partial circuit diagram of FIG. S _D' s 1 to 11 are patterns of reference pulse switches for generating reference pulses, and G is a ground.

In the present camera, after taking out the photographed cartridge C from the camera, the spool shaft 33 is automatically set to an angle at which the unused and partially used cartridges C can be loaded. . That is, after the film rewinding is completed and the cartridge C is taken out, the feeding motor described later automatically rotates in the rewinding direction again,
When the contact piece 42 detects that the pattern S _U is ON, it stops.
At this time, the spool 2 is in the state shown in FIG. The phase of the spool 2 of the unused cartridge C and the spool 2 of the partially used cartridge C is 180 °.
Both of them can be fitted together with the spool shaft 33 as they are.

At the end of rewinding, the spool shaft 33 is controlled so that the spool 2 of the cartridge C is stopped at the position indicating each usage state. The number of pulses generated from the pulse generation printed board 41 is used for this control. I am using. That is,
The number of S _D pulses is counted from the S _U ON position to stop rewinding. For example, when an unused cartridge C is loaded, when rewinding without shooting: stop at S _U ON, and unused display setting When rewinding without shooting all frames: 6 th S _D ON from S _U ON
Stop at, and rewind after partial frame display setting: Shoot all frames: S _D ON after S _U ON

Next, a feeding mechanism will be described in which the film F is pulled out from the cartridge C and wound up one frame at a time and then rewound into the whole frame cartridge 1. FIG. 14 is a plan view of the film feeding mechanism, and FIG. 15 is a perspective view thereof.

In FIG. 14 (A), a feeding motor 61, which is a drive source for feeding the film, is built in a reel 62 around which the film F fed from the cartridge C is wound.
A motor pinion 63 that is directly connected to the rotation shaft of the feeding motor 61 is provided above the reel 62. The driving force from the motor pinion 63 is transmitted to the second sun gear 70 via the intermediate gears 64 and 65, the first sun gear 66, the intermediate gears 67 and 68, and the fourth sun gear 69, but from the cartridge C to the film. F reel
At the time of winding to wind on 62, the motor pinion 63 rotates counterclockwise and the second sun gear 70 rotates clockwise, so that it carries the second planetary gear 72 meshing with the second sun gear 70. The second planetary lever 71 rotates clockwise, meshes the second planetary gear 72 with the spool gear 73, and rotates the spool gear 73 clockwise. When the film F is rewound from the reel 62 into the cartridge C, the motor pinion 63 rotates clockwise and the second sun gear 70 rotates counterclockwise. The second planetary lever 71 carrying the meshing third planetary gear 74 rotates counterclockwise, meshes the third planetary gear 74 and the spool gear 73, and the spool 2 of the cartridge C together with the spool gear 73 counterclockwise. Rotate in the direction.

On the other hand, the first planetary lever 76, which carries the first planetary gear 75 meshing with the first sun gear 66, rotates clockwise during winding, and the reel gear 77 is rotated by the first planetary gear 75.
Is driven to rotate the reel 62 together with the reel gear 77 in the clockwise direction. Further, during rewinding, the first planetary lever 76 rotates counterclockwise, so the driving force of the first planetary gear 75 is not transmitted to the reel gear 77, that is, the driving force of the film motor 61 is applied to the reel 62. Is not transmitted.

In the film feeding mechanism having such a structure, when the film motor 61 is rotated counterclockwise, the spool 2 in the cartridge C is rotated clockwise, and the tongue end Fd of the film F is illustrated. Send it out between the rail surface of the main body and the pressure plate 81. Further, although the film F is fed by the rotation of the spool 2, the tongue end portion F of the film F is
When d passes between the magnetic head 85 and the camera body, the film F may be deformed in the vicinity of the connecting portion between the spool 2 and the film F due to a feeding load, and stable film feeding may be impossible. is there. Therefore, after the tongue end Fd of the film F is fed out, the film is fed to the reel 62 by the drive roller 78, and the driving force is used to feed the film. Therefore, even when the film F passes between the magnetic head 85 and the camera body, an excessive load is not applied to the vicinity of the connecting portion between the spool 2 and the film F, and stable film feeding is performed.

The pressure plate 81 is pressed against the rail surface by a pressure plate spring 82. A pressure plate roller 83 integrally formed coaxially and a fourth planetary gear 79 face each other substantially at the center of the pressure plate 81 in the film feeding direction, and the fourth planetary gear 79 is the fourth planetary lever 80.
And is meshed with the fourth sun gear 69. The center of the fourth sun gear 69 is provided in the cartridge C direction with respect to the center of the fourth planetary gear 79.

When the film motor 61 rotates counterclockwise, the fourth sun gear 69 also rotates counterclockwise.
The fourth planetary lever 80 also rotates counterclockwise. Therefore, the drive roller 78 feeds the film F toward the reel 62 while sandwiching the film F with the pressure plate 81. The film feeding speed by the drive roller 78 is set higher than the feeding speed by the spool 2, and the spool gear 73 is rotated by the film F faster than the peripheral speed of the second planetary gear 72. Therefore, the second planetary gear 72 rotates counterclockwise and disengages from the spool gear 73, so that the feeding force of the film F is transmitted only from the drive roller 78. Also, the film F
Since the film is fed by the driving roller 78 even if the pressure plate 81 or the magnetic head 85 feeds the film, the film F can be fed without being deformed in the cartridge C.

As a matter of course, the driving roller 78 is provided at one end outside the photographing screen. Drive roller
A pressure plate roller 83 is provided in the pressure plate 81 so as to face 78.

FIG. 14B shows a driving roller during film feeding.
78 is an enlarged view of 78 and the pressure plate roller 83. Clearance (cl) is provided by 0.1 to 0.2 mm and retracted so that the pressure plate roller 83 does not protrude from the surface of the pressure plate 81 due to manufacturing error.

FIG. 14C is an enlarged view of the drive roller 78 and the pressure plate roller 83 when a film is not loaded. The drive roller 78 contacts the pressure plate roller 83 to prevent abrasion.

The tongue end Fd of the film F passing through the pressure plate 81
Passes through the magnetic head 85 and is then wound around the reel 62 by a well-known back cover roller and body roller (not shown). Note that the magnetic head 85 performs at least one of reproduction of film information and recording of photographing information of the camera.

When the tongue end Fd of the film F is wound around the reel 62, the feeding force of the film F is transmitted from the reel 62.
The film feeding speed by the reel 62 is set higher than the film feeding speed by the drive roller 78, and the fourth planetary gear 79 rotates faster than the peripheral speed of the fourth sun gear 69 by the film F. Therefore, the fourth planetary gear 79 rotates clockwise, and the drive roller 78 separates from the film F.

In this way, when the tongue end portion Fd of a predetermined length is fed and the perforation Fc of the first frame is fed to the position of the photoreflector 91 for perforation detection, the feeding is stopped and one frame is stopped. It is possible to shoot the eyes.

In this way, one frame is photographed one by one, and the number of photographed frames of the loaded film is determined by the bar code disc 1
Since the camera reads it in advance and stores it in the E ² PROM, when the shooting is completed up to the predetermined final frame, the feeding motor
61 is driven in reverse. Then, the third planetary gear 74 meshes with the spool gear 73, and the spool 2 rewinds the film F into the cartridge C. Here, since the first sun gear 66 also rotates in the reverse direction, the meshing of the first planetary gear 75 and the reel gear 77 is also released, and the reel 62 does not receive the driving force of the feeding motor 61, so that it can be rewound. Further, since the fourth sun gear 69 also rotates in the reverse direction, the fourth planetary gear 79 rotates in the direction away from the film F, the pinching of the film F by the drive roller 78 and the pressure plate roller 83 is released, and the drive roller 78 rewinds. Does not become a load of.

In the above feeding mechanism, a stopper is naturally provided near the first planetary lever 76, the second planetary lever 71 and the fourth planetary lever 80 so as not to rotate more than a predetermined angle. It is necessary, but omitted in the figure.

Further, in FIG. 15, when the bar code disk 1 is rotated by the rotation of the spool gear 73, the bar code information is read by the photo reflector 34 for bar code reading as described above.
Read by.

Further, two LEDs 93 are provided in the lower center, and optical information Fg is optically recorded on the film F. In this case, 2-bit information can be recorded.

In the camera of this embodiment, when it is desired to use films having different sensitivities, the loaded film is rewound in the middle without shooting all frames, and reloaded at a later date,
Since the presence or absence of shooting is recorded on the magnetic track Fe,
You can automatically wind up to unexposed frames. However, as shown in FIG. 15, since the magnetic head 85 is located on the reel 62 side of the shooting screen Fa, it is overwound when it is detected that it is an unexposed frame, and therefore a predetermined amount is rewound. Must-have. In order to secure the positional accuracy of the shooting screen Fa, in this embodiment, after rewinding by a required amount or more, winding is performed again and stopped at the position of the first unexposed screen.

However, as described above, the reel 62 and the spool 2 are
When the feeding mechanism is switched from rewinding to winding while the film is stretched between the first planetary gear 75 and the reel gear.
If the mesh of 77 is faster than the disengagement of the third planetary gear 74 and the spool gear 73, the film feeding speed by the reel 62 is faster than the film feeding speed by the spool 2, so the reel gear 77
The reel 62 is rotated by the drive of and the film F is wound up,
The film F causes the spool gear 73 to rotate via the spool 2 and the spool shaft 33. As a result, the third
The planetary gear 74 and the spool gear 73 cannot be disengaged from each other and the meshing continues, but since the rotation speed of the spool gear 73 by the film F and the rotation speed of the spool gear 73 by the third planetary gear 74 are different, Eventually, the feeding motor 61 stops.

For this purpose, a play joint as shown in FIG. 16 is used. FIG. 16 (A) is a vertical sectional view thereof. First planetary gear 75
The idle gear 95 is rotatably coaxial with the reel gear 77.
Mesh with. A drive pin 75a is provided upright on the first planetary gear 75, a C-shaped groove 95a is bored on the idle gear 95, and the drive pin 75a is inserted into the groove 95a. As a result, at the time of winding, as shown in FIG. 16 (B), the first sun gear 66 rotates, and even if the first planetary gear 75, that is, the drive pin 75a rotates in the direction of the arrow, it rotates nearly one rotation. Until the idle gear 95 does not rotate,
The idle gear 95 rotates only when the drive pin 75a comes into contact with the side wall 95b of the idle gear 95. Therefore, at the initial stage when the rewinding is switched to the winding and the meshing of the third planetary gear 74 and the spool gear 73 is not disengaged, the reel gear 77, that is, the reel 62.
When the driving force is not transmitted to the reel 62 and the driving force is transmitted to the reel 62, the third planetary gear 74 and the spool gear 73 are disengaged. Note that, contrary to FIG. 16, a groove may be provided in the first planetary gear 75 and a drive pin may be provided in the idle gear 95. Further, since the film feeding speed by the reel 62 is faster than the film feeding speed of the spool 2, the idle joint is not necessary for switching from winding to rewinding.

[Table 3]

First, the main flow chart is shown in FIG.
It will be described based on.

In flow 601, resetting is performed by loading the battery 510, and the program starts. On the 602, reset ports such as switch inputs, flag and R
Clear the contents of AM.

Then, at 603, the flag and R are read from the E ² PROM.
The state before AM reset is read. At 604, it is judged from the flag F _C whether or not the cartridge C is loaded before the reset, and if there is not, the routine proceeds to 605. In 605, the cartridge loading switch S _C is detected, and when not loaded, it is detected in 606 to 608 whether the spool shaft 33 is in the initial position. If it is not in the initial position, the spool shaft 33 is rotated by the rotation of the film feeding motor. , Set to the initial position. At 609, the cartridge lid switch S _B is detected. If it is detected to be open, then at 610 the flag F _B is set. 609
In when it is detected that the lid is closed, the determination of F _B at 611. This is for autoloading. At 612, the main switch S ₀ is detected, and if 0, 613
Turn the power off with 1 and turn it on with 614.

At 615, the opening / closing of the cartridge lid switch S _B is detected, and if it is open, no further operation is performed.

At 616, the rewind switch S _R is detected, and when it is pressed, the rewind is performed halfway only when it is judged at 617 that the cartridge C is present, and when there is no cartridge C, the rewind is not performed. . Release switch S _{1 for} 618
It is determined whether or not is pressed, and if it is pressed, light measurement and distance measurement are performed in 619, it is determined in 620 whether the photometry result is low brightness, and if it is low brightness, strobe charging is performed in 621.

At 622, the opening / closing of the cartridge lid 30 is detected, and if opened, the process returns.

In 623 and 624, the release switches S ₁ and S ₂ are detected, and when S ₂ is pressed, focus adjustment is performed in 625,
The shutter is driven to perform exposure. At the same time, the optical information F _g is optically recorded on the film F by the LED 93 according to the mode selected by S _A. At 626, it is determined whether or not the exposure operation has been correctly performed. If not, at 627, the flag F _SE is set, the flag is stored in the E ² PROM, and then the error routine E2 is executed. If the exposure operation is correctly performed, it is detected at 628 whether the cartridge C is loaded, and if not, the process returns to the original state, and if it is performed, the winding operation is performed after 629. The operations after 629 will be described in detail later.

Next, the auto load routine is shown in FIG.
A description will be given based on the flowchart. In 609 of the main routine, the closed state of the cartridge lid 30 is detected, and
If it is determined that the lid has been opened just before 11, detects whether the cartridge C is loaded in 639 after resetting the flag F _B at 638, loaded before the cartridge cover is opened by 640 if it is loaded Detect whether it has been done.
This is the case when the lid is opened in the middle of shooting with the cartridge C loaded. Here, if it is determined that the cartridge C is newly loaded, the automatic load routine of 641 is entered, and it is determined at 642 whether or not the automatic load is normally performed by the flag F _C. If there is an error, the error processing routine is executed. If not, the flag F _C is set and the process returns.

When the auto load routine is entered, the flag FL indicating that the auto load is being _executed is set at 711, and E ² is set.
After storing in the PROM, the feeding is started at 712, the number of barcode readings is set in R _DX , and the timer t ₁ for detecting the autoload error is set. Here, the number of times the bar code is read is set to 24 because the reference pulse switch consists of 12 patterns per revolution, and the S _D ON-O
This is because if the FF is repeated 24 times, all the barcode blocks can be read in one round.

At 713, this change in the state of S _D is detected, and 714
In subtract one bar code from the read count R _DX, repeated until R _DX becomes 0 at 717. At the same time, at 715, it is detected whether or not the leading edge of the film has passed over the photo reflector 91,
When it is detected, the t ₁ timer is reset at 716. When the bar code has been read, it is detected at 718 whether or not the leading edge of the film has passed. If it cannot be detected within t ₁ hours, it is determined as an autoload error, and an error routine is skipped.

In this system, the first frame faces the photographing frame when the feeding is stopped at the time when two perforations are detected during auto loading, so the number of perforations to be counted at 720 is 2 R
Set to _CP , set the number of frames and film sensitivity obtained from the bar code information to R _EX and R _ISO, and set the flag F _DX indicating that the bar code information reading is completed,
Store in E ² PROM. At 721, the first perforation Fb is detected. Here, if the first perforation Fb cannot be detected within t ₂ within a certain period of time, it is determined as an autoload error.

When the first perforation Fb is detected
Set R _CP and R _SP with 723, store in E ² PROM, 72
Read the magnetic information at 4.

At 725, it is determined whether or not the magnetic information can be correctly read. If the magnetic information cannot be read, the routine proceeds to an error routine E5. At 726, it is determined from the magnetic information whether the loaded cartridge C is unused or partially used. If not partially used, proceed to 727, and within the fixed time t ₃ , the second perforation Fc
There the detectable, R _SP, R _CP, the feed sets F _L stops at 729, the routine returns after storing the E ² PROM. t ₃
If the second perforation Fc cannot be detected within this range, it is determined as an autoload error.

Here, t ₁ , t ₂ , and t ₃ will be described in detail. As shown in FIG. 15, the distance from the center of the cartridge C to the photo reflector 91 is a, and the photo reflector is
The distance from 91 to the center of the reel 62 is P ₁ a, the distance from the photo reflector 91 to the center of the drive roller 78 is P ₂ a,
If the distance from the film tip to the first perforation Fb is r · d and the distance from the first perforation Fb to the second perforation Fc is d, then t ₁ ,
t _2, t ₃ the length a, rd, may be set by the feeding speed time proportional to the ratio of d. However, in the present embodiment, the feeding speed of the cartridge C, the feeding speed of the drive roller 78, and the winding speed of the reel 62 are different from each other, and therefore the speed difference must be taken into consideration. Here, the cartridge C
The feeding speed of the drive roller 78 is q ₂ v, and the winding speed of the reel 62 is q ₁ v, then t ₁ , t ₂ , t ₃
Can be expressed as follows, and it is desirable to set the time by each value.

[0076]

[Equation 1]

However, it is not possible that the delivery speed immediately becomes the speed v at the start of the autoloading, and it is also considered that the leading end of the film is difficult to come out of the cartridge depending on the rising time of the motor and the condition of the film in the cartridge. Therefore, it is more desirable to set t ₁ to be slightly longer than the value obtained by the equation, and the value to be made longer is determined by an experiment or the like.

Further, in this embodiment, the magnetic head 85 is provided in the film path, and when the leading end of the film reaches the magnetic head 85 during auto loading, the film feeding speed may be reduced or the film may be stopped for a moment. Therefore, it is more desirable to set t ₂ slightly longer than the value obtained by the formula in consideration of this. The lengthening value may be set to an appropriate value through experiments or the like.

If it is judged at 726 that the film is partially used, at 731, the number of photographed frames is taken into R _ED from the magnetic information, and the flag F _U indicating that the film is partially used is set.

At 732, the magnetic information is used to determine whether the image was taken in the prewind. When the image is taken in the prewind, it is possible to take the image from the first frame to the frame before the already photographed frame. Therefore, the number of frames that can be photographed is the total number of frames
-Because it is the number of frames that have been photographed, the flag is set together with the flag at 738, and the second perforation F _C is detected at 739. It is the same as 728 that an error occurs if the second perforation F _C cannot be detected within t ₃ here.

When the second perforation F _C is correctly detected, the RAM and flag are set in 741 and 742, the feeding is stopped, the data is written in the E ² PROM, and the process returns.

In the case of non-prewind, the number of photographable frames is the total number of photographed frames-the number of photographed frames, but since the frames that have not been photographed must be fed, the number of perforations to be counted is the number of photographed frames. 2 times +1
Set it to R _CP at 733.

In 734 to 737, R _SP and R _CP are obtained each time the perforation is detected, and stored in the E ² PROM each time, and when R _CP becomes 0, the flag is set to 742 and the feeding is stopped. , E ² PROM and return.

If the leading edge of the film or perforation cannot be detected within the specified time, an error routine is performed. If automatic loading error is detected, skipping the automatic loading error routine 750 in FIG. 20, sets the flag F _AE, flag F _R1 indicating that the rewinding showing the autoload error 751 to reset the F _L, E ² Store in PROM and start rewinding.

If R _SP is not 0 at 752, the process proceeds to 753, where 75
From 3 to 755, count perforations until R _SP becomes 0. When R _SP reaches 0, the 756 detects that the leading edge of the film has passed, and then waits for a predetermined time at 757 to ensure that the leading edge of the film has been wound into the cartridge.
By detecting the reference position S _U at 758, the spool is returned to the state before loading, and at 759, F _R1 is reset and E ² PROM
Then, the rewind is stopped. If the perforation cannot be detected within 75 seconds in 753, it is determined that the rewinding is abnormal, the flag F _RE indicating the rewinding error is set, and the process goes to 757.

Next, the rewinding routine will be described with reference to FIGS. If the number of remaining frames in the film is 1 in 629 in the main flow, the rewind routine of 800 is skipped.

In step 801, F _K is set, R _ED and R _CX are calculated, feeding is started, and the result is stored in the E ² PROM. 802
At 803, magnetic recording is started after the first perforation is detected at. When the magnetic recording is completed at 804, the second frame cannot be detected because the second frame does not have the second perforation, so at 805, the flag F _R1 indicating the rewinding is set,
Store in E ² PROM and start rewinding.

At 806, it is determined whether or not the cartridge lid 30 is opened during rewinding. When opened, at 807, the rewinding is stopped, and at 808, it is determined whether or not the cartridge lid 30 is closed and closed. At 809, rewinding starts again.

At 810, the first perforation is detected after the start of rewinding. Here, it is possible that perforation cannot be detected immediately due to film slack, etc., so the error detection time for the 811 was set to be long.

When the first perforation is detected at 810, R _SP is set at 812, stored in the E ² PROM, and the process proceeds to 813. 814 to 825 detect perforations. 81
At 3, it is determined whether the number of perforations is even or odd. If the number is even, the part where the perforation interval between screens is short is detected. If the number is odd, the part where the perforation interval is long is detected. Therefore, the error detection time when detecting the perforations at 818 and 824 is 819 respectively. , 825 are different.

Reference numerals 814 to 817 and 820 to 823 determine whether or not the cartridge lid 30 is opened during the detection of the perforation during the rewinding. When the cartridge lid 30 is opened, the rewinding is stopped at 815 and 821. At 822, it is determined whether or not the cartridge lid 30 is closed, and if closed, rewinding is started again at 817 and 823.

At 826, R _SP is calculated and stored in the E ² PROM, and at 827 it is judged whether the number of perforations is 0 or not.

Reference numerals 828 to 829 determine whether or not the cartridge lid 30 is opened during the detection of the leading edge of the film. When opened, the rewinding is stopped at 829 and the cartridge lid 30 is opened at 830.
Is closed, and if closed, rewinding is started again at 831.

At 834, it is determined whether R _SP is 1 or not. When the number of perforations becomes 1, the magnetic head reaches the magnetic recording portion of the film tongue end portion F _d .
This is for magnetic recording. In 835, magnetic recording indicating the end of shooting is performed.

At 832, it is detected whether or not the leading end of the film has passed over the detection element, and at 833, a waiting time of 3 seconds is made. After the leading end of the film is securely wound into the cartridge C, the use indications at 841 to 847 are displayed. The spool 2 is stopped at the position indicating that it has been used. First, at 841, the reference position is detected. The used position is 210 degrees from the reference position when loaded as an unused film, and 30 degrees when loaded as a partially used film.
Determine whether it is unused or partially used at the time of loading, and set the number of reference signals to be detected for angle detection in 843 and 844.

In 845 to 847, the switching of the reference signal is detected, and when the switching is performed the specified number of times, each flag is reset in 848 and the rewinding is completed.

At 849, the end of rewinding is displayed on the display unit. When the rewinding is completed, the lid of the cartridge chamber is opened, the camera is not operated until the cartridge is taken out, it is detected at 850 to 853 that the cartridge is taken out, and then stored in the E ² PROM, and the operation is ended.

Next, a case where the midway rewind switch is pressed at 616 will be described. If a midway rewind routine is entered at 860, a flag F _R2 indicating that midway rewind is being performed at 861
Is set, stored in the E ² PROM, and rewinding is started.

862 to 889 perform the same operations as the rewinding routines 806 to 833. However, in the magnetic recording of 891, recording is performed by rewinding midway to the tongue end portion F _d of the film. The recorded contents may be rewinding on the way, normal wind, the number of frames taken, and the like.

When the leading edge of the film is completely wound into the cartridge C at 889, the reference position for performing the usage indication is detected at 894. When it is loaded as an intermediate use film when it is loaded, it jumps to 848 when the reference position is detected at 893 in order to perform the intermediate use display again, and the rewinding is stopped as it is. When it is loaded as an unused film when loaded, the number of switching of the reference pulse to be detected must be R because it must be rotated 180 degrees from the reference position and then stopped in order to display the in-use display.
_{When SD} is set to 12 and signal switching is detected 12 times in 896 to 898, jump rewind is stopped in 848.

Next, various error routines will be described.

First, the autoload error will be described with reference to FIG. When an autoload error occurs in the 641 autoload routine, the flag F _AE indicating the autoload error is set to 1, so 642 jumps to 900. 901
Then, a warning display indicating an autoload error is displayed, and 902 detects whether or not a rewind error has occurred. 903, 904,
The release switch S ₁ and the cartridge lid switch S _B are detected. 907 when the release switch S ₁ is detected
The warning display is canceled with, the flag is reset with 908, and auto loading is performed again. When it is detected that the cartridge lid 30 is opened, the warning display is canceled at 905, the flag is reset at 906, and the process returns to the first loop.

Next, the shutter error routine will be explained.
It will be explained based on 25. When it is detected in 626 that the exposure is not normally performed, a flag F _SE indicating a shutter error is set in 627, a jump to 910 is performed, and a shutter error warning is displayed in 911. Since it is considered that the shutter error does not open the shutter or the shutter opens all the time, the camera does not operate thereafter, and by repairing, F _SE is reset and returns to the original state.

Next, a diagram of the mid-course thrusting routine is shown.
It will be explained based on 26. It is conceivable that the perforations cannot be detected within the specified time at 632 or 634 when the film is wound. It is considered that the cause is that the bar code information or the magnetic information of the tongue end portion is read, the reading error of the specified number of frames, or the deformation of the film F in the cartridge C. In this case, the tension routine at 920 is entered, and at 921, a flag F _FE indicating abnormal winding and a flag F _R1 indicating rewinding are set and stored in the E ² PROM, and rewinding is started. To do. At 922, the first perforation after the start of rewinding is detected, and if it cannot be detected within the specified time, it jumps to the rewinding error routine. If detected, R _SP is decremented by 1 in 924 and stored in the E ² PROM, and then the normal rewinding routine is returned to. In this case, the fact that the tongue portion of the film is tentatively stretched, the number of frames photographed, etc. are recorded, and the spool 2 is stopped at the position where the usage indication is "used".

Next, the rewind error routine will be explained.
It will be explained based on 27. When an abnormality occurs during rewinding and perforation cannot be detected, the rewinding error routine of 930 is entered.

At 931, a flag F _RE indicating a rewinding error is set, at 932 a warning message indicating that there is a rewinding error is displayed, at 933 the rewinding is stopped, and at 934, it is stored in the E ² PROM. The fact that the cartridge C has been taken out is detected in step 936, and the flag F _RE is reset in step 936 to return to the original state. However, when the rewinding actually stops halfway, the film remains out of the cartridge C. , The cartridge C cannot be taken out. Therefore, when a rewind error occurs, the back cover of the camera is opened and the film is taken out.

Next, the magnetic recording / reproducing error routine will be described with reference to FIG. At the time of auto loading, the magnetic information of the tongue end of the film is read by 724.
If it cannot be read by 5, jump to the 940 magnetic recording / reproducing error routine. This camera cannot determine whether the loaded cartridge C is unused or partially used at the time of loading, and it can determine the partial use by reading the magnetic information of the tongue end. Therefore, the magnetic information can be read. If not, the use of the cartridge C is prohibited to prevent double exposure of the partially used film. However, in order to prevent shooting from becoming impossible due to a temporary reproduction error, a flag F _ME indicating that there was a magnetic reading error was set at 941 and after being stored in the E ² PROM, it was once before the first perforation Fb. Rewind to 944, wait for time at 944, reset F _{ME at} 945 and 946, memorize, wind again, detect perforation passage at 947, and read magnetic information again at 950. Although will return from 951 if successful where the reading of the information based on, a warning display of the magnetic information reading failed at 952 if it fails, 953 in F _ME
Is set again and stored in the E ² PROM, and then the film is rewound. Then, after the film front end is completely wound into the cartridge C in 954 to 957, the reference position is detected in 959 to return the use indication to the state before loading, and the rewind is stopped in 960. The magnetic recording / playback section is an indispensable part for distinguishing the partially used film.If the magnetic information cannot be read, double exposure accident of the partially used film may occur, so the warning display is continued on 961. , Do not operate the camera after that. In this case, it does not recover until repair is done. Further, if the perforations are not detected within the specified time in 943, 948, and 955, it goes without saying that each error routine is skipped.

Finally, the initial judgment routine will be described with reference to FIG. If the battery 510 is disconnected during camera operation, is reset to the microcomputer, returns to 601 in the main flow, flag E ² PROM, the contents of the RAM is stored, reads the contents of the E ² PROM in 603 To be done.
If the cartridge C is loaded before the battery 510 is removed, the process jumps from 604 to the initial determination routine.

At 971, it is judged from the flag whether or not the automatic loading is in progress, and if the automatic loading is in progress, jump to 980. In 980, it is determined whether or not the bar code information is read, and if not read, the film is rewound once in 981 and after waiting for 3 seconds so that the film is reliably wound in 982, the auto is restarted. To load, return to the auto load routine.

At 983, the number of times perforation is detected after the start of autoloading is checked. This is because the magnetic information of the film is read after detecting one perforation. If the perforation is not detected yet, the process proceeds to 984, the film feeding is started, and the process returns to the autoload routine. If 983 determines that perforation has already been detected, the battery 510 is
Since it has been removed, the film is rewound once before the perforation at 985 to 987, the film feeding is restarted at 988, and the process returns to the autoload routine.

At 972, it is detected whether or not an autoload error has occurred, and if so, jump to an autoload error routine. At 973, it is determined whether the feeding is in progress. If it is in the middle of feeding, proceed to 989 to determine whether or not the number of perforations to be counted is two. If it is 2, the first perforation has not been detected yet, so feeding is started at 989 and the process returns to the main flow. If the perforation to be counted is not 2, it means that the magnetic recording was in progress, so after rewinding before the first perforation at 990 to 992, feeding again at 993 and returning to the main flow. , Magnetic recording will be performed again.

At 974, it is determined whether or not the rewind is being performed. If rewinding is in progress, rewind starts at 994. 995 measures the number of perforations from the tip of the film.
If this number is 0, only the leading edge of the film should be detected after this, and if it is not 0, the remaining perforations must be detected, so the location of the return to the rewinding routine is different. 975 is a judgment as to whether or not the rewinding is being performed on the way, but it is the same as 994 and 995 except that the place of return is different.

At 976 to 978, the presence or absence of a shutter error, an autoload error, and a rewind error is determined, and if detected, the routine proceeds to each routine. In 979, it is judged whether or not there is a magnetic reading error. If there are errors go to 998, 9
If it is determined in 98 that rewinding is in progress, rewinding is started in 999 and the process returns to the error routine. If the flag is not detected by 979, it is determined that the camera is not operating before the battery 510 is removed, and the process returns to the standby state of the main routine.

Next, the relationship between the film used in this embodiment and the taking lens will be described. Polyethylene naphthalate is used as the base of the film, and polyethylene naphthalate has a characteristic that it mainly reacts with ultraviolet rays of 220 to 380 nm and emits fluorescence. Therefore, due to the ultraviolet rays received at the time of photographing, the fluorescence from the film base continues after the shutter is closed and before the film is developed, so that fogging occurs even if the amount of received ultraviolet rays is small and the amount of fluorescence is very small.

Therefore, at least a photographing lens having an optical component formed of a material that does not transmit ultraviolet rays may be used. That is, PMMA (polymethylmethacrylate) which is a plastic material, SF type glass, or L
An optical system having at least one optical component made of aSF glass may be formed. In addition, in order to expand the degree of freedom of the configuration of the optical system and increase the efficiency of ultraviolet ray cut,
The UV cut coating may be used in combination with the optical component made of the above material, or may be applied to the optical component made of another material. In particular, PMMA cuts ultraviolet rays of 380 nm or less and has good moldability, so aspherical lenses can also be processed.
Most preferred as a material used for an optical system.

FIG. 30 is a diagram of a photographing lens used in this embodiment, in which the first lens L ₁ is LaF01 as a material used.
0, the second lens L ₂ is SFL6, the third lens L ₃ is LaF
05, the fourth lens L ₄ uses PMMA. Therefore, the main photographing lens prevents the transmission of ultraviolet rays by the second lens L ₂ and the fourth lens L ₄ .

Next, the camera and film cartridge having the inspection function of the present invention will be described.

The cartridge C, which is a film cartridge used in the camera of the present invention, has a magnetic storage unit capable of recording film information and shooting information at the time of shooting on the magnetic layer, as described in FIGS. A film,
It is a cartridge used in a camera system that uses a film cartridge having a rotatable bar code disk integrally with a spool for recording film information in a bar code.

Information indicating that the cartridge used for checking the function of the camera is a cartridge for checking the function of the camera. In the cartridge of the present embodiment, the magnetic storage unit at the leading end of the film is magnetic. The information is recorded on the track Ff and / or the bar code disk 1.

Information indicating that this is a cartridge for functional inspection is recorded in digital form on the magnetic track Ff, and on the bar code disk 1, for example, as shown in FIG.
It is recorded with black and white bar code information as indicated by 31. The magnetic information of the magnetic track Ff is recorded by the magnetic head 85.
(See FIGS. 14 and 15). In addition, the bar code information of the bar code disk 1 is the photo reflector 34 (Fig.
15)).

When the camera detects from the read information that the loaded cartridge is a cartridge for functional inspection, the camera automatically switches to the functional inspection mode.

Information indicating that the cartridge is a functional inspection cartridge is a camera which is capable of reading both magnetic information and bar code information in a production process using this cartridge, or only magnetic information or bar information. Depending on the camera that can read only the code information, the cartridge in which the information is recorded according to the camera is used.

In any case, the camera automatically switches to the function inspection mode by loading the cartridge in which the information indicating the function inspection cartridge is recorded into the camera as described above. The inspection mode described will be stably executed.

Next, referring to the flow chart of FIG. 32, the flow in which a cartridge for function inspection is loaded into the camera, the camera automatically switches to the function inspection mode and the inspection of each function is executed will be described.

In FIG. 32, at 201, the main switch button 23 (see FIG. 7) or a switch in place thereof is used to turn on the power of the camera and start the program.

At 202, the cartridge is loaded into the camera, and at 203, the barcode information of the barcode disc is read. When it is found that the cartridge is a functional test cartridge, the process proceeds from 204 to 207.

On the other hand, when the bar code information at 204 cannot be read as a cartridge for functional inspection,
Alternatively, when there is no information that the cartridge is a functional inspection cartridge, the magnetic information is read at 205. Then, when it is determined in 206 that the cartridge is a functional test cartridge based on the magnetic information, the process proceeds to 207. When there is no magnetic information in 205 and there is no information in 206 that it is a cartridge for functional inspection, the process proceeds to the normal photographing modes 217 and 218.

By proceeding to 207 as described above, the camera automatically switches to the function inspection mode.

Next, at 207, for example, the release button S ₁ is pressed. When the release button S ₁ is pressed, the AE inspection mode is executed at 208 in the camera of this embodiment.

The AE inspection mode is the following inspection mode. That is, a light source with a certain brightness, such as LV9
Set the camera toward the light source of. The value or a value corresponding to the value is displayed on the LCD 22 (see FIG. 6) which is the display unit of the camera. If this value is a correct value or within the specified range, it is acceptable, and if it is not the correct value or within the specified range, the photometric circuit is adjusted while looking at the display section.
