As is well known in Japanese Patent Publication No. 118-118, the film loading operation is performed in a dark room. This operation is completed by drawing out the photo film from the cartridge to form a film roll, loading the cartridge and the film roll into the main body, and then attaching the rear cover.

A built-in flash type film unit requires a power supply battery. Conventionally, the power supply battery is loaded inside the unit main body through an opening on the bottom surface side along the film feeding direction, and the opening is covered with a paper box. For this reason, in the film unit assembling process, a photo film cartridge has been loaded, and then a power supply battery has been installed before shipment. However, in recent years, with the downsizing of the film unit, a thin label has come to be used instead of a paper box for an exterior body. If a label is used, there is a risk that the power battery may be removed and removed improperly. For this reason, the opening at the center of the bottom surface of the unit body is closed by a part of the rear cover.

1 and an image inspection apparatus including a determination unit 102. The CCD camera 100 captures an image of the main body 94 with the back side facing upward from above, and sends this image data to the image processing unit 101. The image processing unit 101 compares the luminance value between the captured image and the reference image and sends the result to the determination unit 102. The determination unit 102 stores determination data for determination in advance, determines the result data sent from the image processing unit based on the determination data, and confirms that the charging indicator lamp 37 is turned off. The projector 104 irradiates a part of the main body 94 with light, the reflected light is captured by the camera 100, the captured data is subjected to image processing, and the image-processed data is determined based on the determination data stored in advance. By doing so, the failure of the CCD camera 100 is detected, and the lighting and blinking of the charging indicator lamp 37 is prevented from being overlooked. If it is determined that the charging indicator lamp 37 is lit and blinking, the NG data is sent to the NG discharging step 92 using the well-known transmission means 103. In the case of a film unit having no built-in strobe unit, the charge indicator lamp inspection is not performed.

The drive shaft phase inspection step 91 is performed to prevent the key portion 59 of the cover member 51 of the cartridge 26 from engaging with the key portion 63a of the drive shaft 63 when the film is loaded. This is a step of inspecting whether or not the position is at a position corresponding to the closing position of the lid member 51. The rotational position of the key portion 63a of the drive shaft 63 of the lid closing mechanism is detected using a laser displacement meter, and pass / fail is determined. put out. Here, NG is not set for the one that does not match the closed position.

The NG discharging step 92 is provided before the film loading step 93 in order to eliminate the need to manually remove the photographic films 28 one by one in the dark room when the film unit 10 after film loading is determined to be NG. Here, NG data is sent from each of the above-described inspection processes 86 to 91 using a known transmission means. The transmission means includes, for example, a photo switch disposed between each process and a shift register corresponding to the photo switch. The photo switch detects supply of the main body 94, and shifts based on the detection. When the register shifts the NG data, the main body 94 which is determined to be NG in each process is shifted.
Can be discharged at the time when it is supplied to the NG discharge step 92.

In 05, the lid member 51 is detected by the reflection-type photoelectric sensor via the film feed port 49, and it is determined whether or not the lid member 51 is in the closed position based on whether or not the detection is possible. And what is not the closed position is NG.

The spool phase inspection step 106 checks whether the rotational position of the spool 31 is constant by confirming the exposed position of the used display component 57 using a reflection type photoelectric sensor. This inspection is performed based on, for example, whether or not the used display component 57 can be detected through the display window 58a indicating an unused state. If the used display component 57 cannot be detected through the display window 58a, it is determined to be NG.

In the film type inspection step 107, the bar code on the label 50 of the cartridge 26 is read by a bar code reading sensor to check the type of the photographic film 28. As is well known, the photographic film 28 loaded in the film unit 10 is determined to match the information input to the input unit 84. By checking whether or not this is the case, before loading the film, the photo film cartridge 25 is loaded into the film unit 10 after loading the film.
It is possible to eliminate the troublesome work of taking out from the device.

In the NG discharging step 108, the inspection results of the respective inspection steps 105 to 107 of the photographic film cartridge 25 are sent, and the photographic film cartridge 25 determined to be NG in each step is discharged when supplied thereto.

As for the rear cover 21, the one that matches the information input to the input section 84 is processed from the molding step 110 to the type inspection step 1.
After that, it is sent to a locking claw inspection step 112 and an NG discharge step 113 in this order, and then supplied to a film loading step 93. The supply mode of the rear cover 21 is such that the pull-top type bottom lids 34 and 35 are kept open.

In the locking nail inspection step 112, the rear cover 21
The presence or absence of a plurality of locking claws is inspected using a laser meter.
In particular, if the locking claws 65 of the bottom lid 34 are damaged,
Since the lid closing mechanism does not operate, such inconvenience must be checked before the film loading step 93.

In the NG discharge step 108, each inspection step 11
1,112 inspection results have been sent,
After being made NG in 112, the cover 21 is discharged when the cover 21 is supplied here.

The film loading step 93 is a dark room. The dark room is provided with three inlets for taking in the main body 94, the photographic film cartridge 25, and the rear cover 21, and an outlet for taking out the film loaded. As described in JP-A-6-332118, these inlets and outlets have a double shutter structure that does not allow light to pass through when taking in and taking out. These shutters operate alternately. The transfer of the taking-in and taking-out uses a pair of robot arms arranged on both outer sides of the double shutter. One of the robot arms is placed in the interior once partitioned by the double shutter in response to the pull of one of the shutters, and after the switching operation of the shutter that closes one shutter and opens the other shutter, the other robot arm is turned off. The object placed inside is taken into the dark room or taken out of the dark room.

As shown in FIG. 13, the rear cover 21
Each of them is taken into the dark room 93a. After being taken in, the cover 21 is arranged in a fixed direction with the bottom lids 34 and 35 kept open, and then placed in order on a plurality of rear cover pallets 116 arranged on the index table 115. Is placed.

The drive shaft 130 is provided along the vertical direction, and its tip projects from the cartridge holder 124. The origin detection unit 125 is for stopping the key unit of the drive shaft 130 at a predetermined rotation position. The pulse encoder 133 is for detecting the rotation amount of the drive shaft 130.

The process controller 128 rotates the drive shaft 130 to the origin position based on a signal obtained from the origin detection unit 125 before the transfer of the cartridge 26 is performed. This origin position is adjusted to the rotational position of the spool 31 inspected in the spool phase inspection step 106 described above. Therefore, when the cartridge 26 is transferred,
The key portion 13 of the drive shaft 130 is inserted into the key groove 59 of the spool 31.
0a is securely engaged.

The film guide section 126 is composed of two guide members 135 and 136 for linearly guiding the front end 41 of the film fed from the cartridge 26. These are arranged in a straight line, and the guide member 135 closer to the film feed port 49 is fixed.
Further, the guide member 136 in the far direction is provided so as to be able to retreat from the film sending locus. If the type of the film unit 10 at that time is of the type with built-in flash, the process controller 128 drives the cylinder 137 to insert the distant guide member 136 on the film sending locus, and the type of the type without built-in flash. In this case, the film is retracted from the film sending locus.

The distance between the cartridge storage chamber 27 and the film roll chamber 29 is adjusted.

After detecting the cartridge 26, the process controller 128 drives the motor 131 to drive the drive shaft 13.
0, and the spool 31 is rotated at a high speed in the film feeding direction. The film tip 41 sent out is
It passes through the guide member 126 and enters the inside of the U-shaped plate member 138 from the open side. Then, the rotation of the motor 131 is reduced when the leading end of the film is detected by the deceleration sensor 141, and the rotation of the motor 131 is stopped when the leading end of the film is detected by the stop sensor 142. This allows
A photo film 28 is pulled out from the cartridge 26 by a length corresponding to the type of the film unit 10. Here, the film leading end portion indicates the edge of the film leading end 41.

During this time, the process controller 128
The number of pulses obtained from the encode pulse 133 is counted, and the key value of the spool 31 at this time is determined from the count value at the time when the film leading end 41 is fed out by a predetermined length, that is, at the time when the driving of the motor 131 is stopped. 60 rotation positions are determined. This position information is sent to the next film roll creation step 122 as spool phase information. When the overrun sensor 143 detects the leading end of the film after stopping the rotation of the motor 131, repetitive control is performed to rewind the photographic film 28 and stop it at the specified length again.

The cartridge 26 from which the film tip 41 has been fed by the specified length is supplied to the film roll preparing / main body inserting step 122 by the transfer machine. This supply is performed by a transfer machine. The transfer machine is a film tip 41
And the cartridge 26 are carried together and lifted along the axial direction of the spool 31, and then supplied to a film roll creation / body insertion step 122. At this time, the member carrying the film leading end 41 is carried at a position slightly closer to the cartridge side from the film leading end. This facilitates the transfer in the next film roll forming step.

Film Roll Creation / Main Body Insertion Step 12
The unit 2 is provided with a unit device that integrates a film roll producing device for producing the film roll 28a and a main unit insertion device for loading the produced film roll into the main unit. This apparatus is provided with a cartridge holder 145, an unwinding shaft 146, a winding shaft 147, and the like, as shown in FIG. These are collectively controlled by the process controller 128.

The cartridge holder 145 is provided with a cartridge detection sensor 148. When the sensor 148 detects the cartridge 26, air suction is started and the cartridge 26 is suction-held. The unwinding shaft 146 is provided with a key portion 146 a at a tip protruding from the cartridge holder 145, and the key portion 146 a is engaged with the key groove 60 of the spool 31.

The unwinding shaft 146 and the winding shaft 147 are arranged at intervals according to the drawing length of the film leading end 41 in the previous step.
The film tip 41 is transferred to the spool 147 from above along the axial direction of the spool 31. Before this transfer, the process controller 128
From the previous film leading end step 121, the cartridge 26
First, the key portion 146 of the unwinding shaft 146
The unwinding shaft phase is adjusted to match the rotational position of the spool 31 when a is pulled out by a specified length.

The unwinding shaft phase adjustment is performed using an origin detection unit, a pulse encoder, a phase adjustment motor 149, and the like. The origin detection unit is a hole 151 provided at one location in the circumferential direction of the disk 150 that rotates together with the unwinding shaft 146.
And a transmission type origin detecting photoelectric sensor 152 for detecting the hole 151 at the origin position of the unwinding shaft 146. The pulse encoder includes a plurality of slits 153 provided at a predetermined pitch on the outer periphery of the disk 150, and a transmission-type rotational position detecting photoelectric sensor 15 for detecting the passage of the slits 153.
4 The motor 149 is a pulse motor and is free except when driven.

The process controller 128 sets the unwinding shaft 146 at the origin position based on a signal obtained from the origin detecting section, and the film leading end step 121 is performed.
In response to the input of the spool phase information, the motor 149 is driven in response to the input, and the number of pulses obtained from the pulse encoder after driving is counted. When the count value becomes a value corresponding to the spool phase information, With motor 149
Of the spool 3 after pulling out the previous film
The unwinding shaft 146 is adjusted to the first rotation position. Thereafter, the transfer machine is controlled to transfer the photographic film cartridge 25 from the film leading end step 121. This ensures that the spool 31 is securely engaged with the unwinding shaft 146 even when the rotation position of the spool 31 when the film leading end 41 is pulled out by the specified length is not always constant in the film leading end step 121. it can.

A split groove 155 for inserting the film tip 41 is formed in the winding shaft 147.
5 is provided with a clip for clipping the film tip 41 inserted from above. The clip is
The film leading end 41 is nipped between the inner wall of the split groove 155 and the inner wall of the split groove 155 by using the bias of a spring. At this time, the film tip 4
Since the drawing-out and the film roll production are performed in separate steps, the leading end of the film can be accommodated in the split groove 155 without protruding from the contour outer diameter.

The origin 155, the joint 157, the motor 158 and the like are connected to the winding shaft 155. The origin detection unit 156 includes a hole 160 provided at one location in the circumferential direction of a disk 159 that rotates together with the winding shaft 147, and a transmission-type origin detection photoelectric sensor 16 that detects the hole 160.
And 1. The motor 158 has a reel 147
To rotate. The joint portion 157 detachably connects a shaft that can be vertically separated from this portion, and performs an operation of transmitting the drive of the motor 158 to the reel 147 when connected.

Before the photographic film cartridge 25 is set, the process controller 128 determines the origin of the reel 147 based on a signal from the origin detecting unit. The winding shaft 147 has the split groove 1
55 is the rotational position along the film tip 41 that has been pulled out.

When the photographic film cartridge 25 is set, the motor 158 is driven in response to the set signal to rotate the reel 147 in the direction of the arrow shown in FIG. This film roll 28a basically includes a winding shaft 147.
And the unwinding shaft 146 is free. However, when the unwinding shaft 146 is free, the film roll 28a is formed in a loosened state, and the roll outer diameter becomes large, which causes a problem that the roll cannot be accommodated in the film roll chamber 29.

Therefore, in this example, a brake mechanism 163 disposed on the opposite side of the cartridge holder 145 with the cartridge 26 interposed therebetween is engaged with the spool 31 to apply a brake to the rotation of the unwind shaft 146 with a predetermined strength. . As the brake mechanism, a mechanism utilizing the moment of inertia of the disk 150 or a mechanism utilizing frictional resistance by a spring may be used. As a result, the film roll 28a is formed while being wound with a predetermined force, and can be formed with a predetermined roll diameter. Further, since the leading end of the film does not protrude from the split groove 155, the leading end of the film is bent out of the cross-sectional profile of the winding shaft 147 during the production of the film roll 28a, so that the film feeding mechanism of the cartridge 26 cannot be reliably moved. Can be prevented.

Between the unwinding shaft 146 and the winding shaft 147,
The transmission type photoelectric sensor 164 sandwiches the film transfer path.
Is arranged. The photoelectric sensor 164 detects the return perforation 48 of the photographic film 28 during the production of the film roll 28a, and sends a detection signal to the process controller 128. Process controller 128
Reduces the driving of the motor 158 when the detection signal is received, and pulls out the photographic film 28 by a length corresponding to two photographing frames from this time. The length of the unwinding shaft 146
Can be managed by using the pulse encoder.

After the photographic film 28 is pulled out for two frames, the driving of the motor 158 is stopped. Thereafter, the motor 149 of the unwinding shaft 146 is driven to drive the photographic film 28.
Slightly into the cartridge 26. In this way, it is possible to prevent the film roll 28a from unwinding due to the loosening of the photographic film 28 wound around the spool 31. As a result, Photo Film 2
8, a film roll 28a is created in a state where it is pulled out from the cartridge 26 by at least one frame from the last photographing frame 47z.

The winding shaft 147 is moved in the film transport direction according to the type of the film unit 10. In this mechanism, the process controller 128 drives the cylinder 166 according to the type of the film unit, so that the motor support plate 165 supporting the motor 158 moves in the film transfer direction, and is provided on the motor support plate 165. The pin 166 is engaged with the support plate 167 supporting the reel 147, and the support plate 167 is moved together with the motor support plate 165 in the same direction. Thus, the interval between the winding shaft 147 and the unwinding shaft 146 can be changed according to the presence or absence of the built-in strobe.

The main unit insertion device uses the unwinding shaft 146 and the winding shaft 147 to form the cartridge 26 and the film roll 2.

And a slide mechanism for moving the unwinding shaft 146 and the winding shaft 147 toward the index table 115.

After the creation of the film roll 28a is completed, the process controller 128 drives the first turning mechanism and the second turning mechanism together. When the first turning mechanism operates, the unwinding shaft 146 and the winding shaft 147 rotate together to a position along the horizontal direction. At this time, the winding shaft 14
7 is separated at the joint 157. When the second turning mechanism is operated, the winding shaft 1 is rotated around the unwinding shaft 146.
47 is rotated upward to be in the state shown in FIG. Thereafter, the slide mechanism is operated, and the cartridge 26 is inserted into the cartridge storage chamber 27 of the main body 94 from the axial direction of the spool 1. At this time, the film roll 28 a on the winding shaft 147 is located at a position separated upward from the main body 94. After the spool 31 is engaged with the winding knob 13, the second turning mechanism is operated, and the unwinding shaft 1 is rotated.
The winding shaft 147 is rotated in the direction opposite to the above-described direction around the film 46, and the film roll 28a is moved to the film roll chamber 29.
