Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film cartridge inspection method and apparatus, and more particularly to a photographic film cartridge inspection method and apparatus for assembling and inspecting a photographic film before storing the photographic film. .

[0002]

2. Description of the Related Art According to U.S. Pat. Nos. 4,834,306, 4,846,418, and Japanese Patent Laid-Open No. 3-37645 by the present applicant, a cartridge is assembled with a resin molded product and a spool is rotated. There is known a photographic film cartridge having a function of sending the photographic film out of the cartridge. This photo film patrone is different from the previous ones, the leader part of the photo film does not protrude from the patrone in both unused and used condition, so that the photo film can be stored more tightly and before and after use. It has the advantage of being easy to handle.

In such a photographic film cartridge,
To prevent the photo film from being sent out by careless rotation of the spool when not in use, there are those with a built-in spool lock mechanism to lock the spool and those with a light-shielding lid member that opens and closes the film passage. is there.

Incidentally, in consideration of manufacturing such a photographic film cartridge, it is necessary to inspect the quality after the completion of the assembly. For inspection, it is common to store the photographic film in the upper and lower cases and then inspect each mechanism.The photographic film cartridge that fails the inspection is disassembled after taking out the photographic film. Even if the malfunction of each mechanism is corrected by mistake, there is a possibility that the photo film may be scratched or damaged when taking out the photo film, and it is impossible to inspect the photo film again, so it should be discarded. Will be done.

Therefore, in the method of manufacturing a photographic film cartridge described in Japanese Patent Laid-Open No. 5-289247, a mechanism that can be incorporated in advance is incorporated into the upper and lower cases of the two parts that make up the cartridge, and then each mechanism is assembled. A method has been proposed in which a spool around which a photographic film is wound is rotatably housed in upper and lower cases after an operation inspection is performed. According to this, since each mechanism can be inspected before fixing the upper and lower cases, it is possible to reduce the number of photographic film cartridges to be discarded.

[0006]

However, in the manufacturing method described in Japanese Patent Application Laid-Open No. 5-289247, there are some cases in which inspection cannot be performed unless the upper and lower cases are combined, and the upper and lower cases are also combined. It is necessary to inspect each mechanism even after it has been completed. For example, since the spool, the lid member and the like are rotatably supported at the joints of the upper and lower cases, it is common to inspect the rotating torque after combining the upper and lower cases. Therefore, the method described in Japanese Patent Laid-Open No. 5-289247 has a drawback that it takes a lot of time for inspection and duplicate inspection occurs, resulting in a decrease in the production capacity of the photographic film cartridge.

Therefore, it is an object of the present invention to provide an inspection method and apparatus for a photographic film cartridge in which inspection is performed efficiently and the production capacity is improved.

[0008]

In order to achieve the above object, according to the present invention, rotation is applied to a spool of a patrone incorporated with a lid member in an open position, and a torque required for rotation is measured. The first step, and the second step of measuring the torque required to rotate the lid member to the closed position,
A third step of rotating the spool in the locked state to measure the spool locking force and a fourth step of rotating the spool in the locked state in the opening position direction to measure the locking force of the lid member
And the fifth step of measuring the torque required to rotate the unlocked lid member to the open position.

As described in Japanese Patent Application Laid-Open No. 6-35123, a photographic film has a tongue-shaped guide plate inserted into the film passage, and the photographic film is used as a guide to guide the photographic film from the rear end side. It can be stored in the cartridge by inserting it inside, engaging the rear end of the photographic film with the spool, and then rotating the spool in the film winding direction. That is, if a lid member, a lid member locking means, a spool locking means, etc. are built in the cartridge in advance and the photographic film is stored after the inspection of each mechanism, the photographic film can be stored without discarding it. It has the advantage of producing Patrone.

Then, as a result of considering that the inspection can be carried out efficiently to increase the production capacity of the photographic film cartridge,
It has been found that it is preferable to configure the steps described in claim 1. That is, according to the first aspect of the invention, the patrone is assembled with the lid member in the open position, and the torque required when the lid member is finally moved to the open position is measured. Since it is in the open position, the photographic film can be stored as it is, the total inspection work can be performed in a short time, and the production efficiency which can improve the quality can be improved.

In view of automatically performing such an inspection, there is a demand for an apparatus that can perform damage without damaging the assembled cartridge. Therefore, according to the device of the fourth aspect, when the drive shaft is not engaged with the spool, it is safe because the drive shaft escapes against the bias of the spring. Needless to say, such a safety mechanism can also ensure the safety of the lid member by providing the drive shaft for rotating the lid member. Further, according to the apparatus of claim 5, the spring that performs the same operation as that described in claim 4 has a buffering effect that alleviates a great rotational impact generated at the moment when the drive shaft and the spool are engaged with each other. Therefore, it is possible to prevent breakage and damage of the spool lock means.

EXAMPLE A photographic film cartridge 10 as described above is
Assemble the Patrone 11 (hereinafter, the state where the photo film 12 is not stored is referred to as "Patrone 11"),
Thereafter, after inspecting the lid member locking mechanism, the spool locking mechanism, etc., the photographic film 12 is stored and shipped as a photographic film cartridge 10. Patrone 11
Indicates that the assembled state is the state in which the lid member 22 is in the open position.

In order to carry out the inspection work efficiently,
Spool rotation torque, bar code reading, lid member closing torque, spool locking force, lid member locking force, and lid member opening torque are performed in this order. The order of this inspection can be freely changed as appropriate.

The spool rotation torque inspection is performed by the device 50 shown in FIG. The spool rotation torque inspection device 50 rotates the spool 13 at a constant torque value and confirms how much the spool 13 has rotated within a constant time. The rotation is preferably carried out by rotating the film in the film feeding direction and the film winding direction opposite thereto. In this embodiment, the constant torque value is 40 g · cm. Therefore, when the torque does not rotate with a torque of 40 g · cm or it is difficult to rotate, the number of rotations within a certain period of time does not reach the specified number of rotations, and therefore the test fails.

The device 50 includes a motor 51 and a torque generator 5.
2. The shafts of the rotary encoder 53 and the inspection drive unit 54 are connected in a straight line by a shaft joint 55. These devices 50 are arranged on a slide table 57 provided on a base 56,
The drive shaft 5 of the inspection drive unit 54 is driven by the motor 58.
9 slides between an engaging position where it engages with the key groove 35 of the spool 13 and a retracted position where it retracts.

When the drive of the motor 51 is input to the input section, the torque generator 52 outputs this drive to the output section by changing the rotation to a constant torque. Then, when a load equal to or higher than a certain torque is applied to the output unit, the input unit and the output unit slip. As this structure, a friction plate method or a hysteresis method combining permanent magnets can be used.

As shown in FIGS. 7 to 9, the drive shaft 59 of the inspection drive portion 54 is formed to have a diameter that fits into the key groove 35 of the spool 13 and is a protrusion that fits into the key receiving portion 35a. The ridge 59a is integrally formed on the outer circumference. By the way, in the assembly of the cartridge 11, since the rotation position of the spool 13 is random, the protrusion 59a of the drive shaft 59 does not fit into the key receiving portion 35a even if the device 50 is simply moved to the engagement position. The drive shaft 59 may push and damage the spool 13. For this reason,
The inspection drive unit 54 has a ridge 59a and a key receiving portion 35a.
A safety mechanism for retracting and preventing damage to the spool 13 when not fitted to a is built in.

The safety mechanism is composed of a holding cylinder 60, a spring 61, and a pin 64. The drive from the output portion of the torque generator 52 is transmitted to the holding cylinder 60, and the protrusion portion 59a is transmitted.
Between the fitting position where the key is fitted to the key receiving portion 35a and the retracted position where the spool 13 is retracted in the axial direction from the drive shaft 5
Hold 9 movably. The spring 61 is arranged in the holding cylinder 60 and biases the drive shaft 59 toward the spool 13. The pin 64 is fixed to the outer periphery of the drive shaft 59,
The drive transmitted to the holding cylinder 60 through the hole 60a formed in the holding cylinder 60 is transmitted to the drive shaft 59. As a result, when the protruding portion 59a of the drive shaft 59 does not fit into the key receiving portion 35a, the drive shaft 59 moves inside the holding cylinder 60 by the spring 61.
The spool 13 is moved to the retracted position against the urging of the spool 13 and does not damage the spool 13. Further, the drive shaft 59 is moved to the fitting position by the bias of the spring 61 at the time when the protruding portion 59a and the key receiving portion 27a coincide with each other due to slight driving of the motor 51. Since the drive shaft 59 moves between the fitting position and the retracted position in this way, the opening 60a is a long hole.

It is desirable that the inspection be performed after the drive shaft 59 and the key groove 35 are securely connected. Therefore, in order to obtain the inspection start timing, an inspection timing measured ring 62 is movably arranged on the outer periphery of the holding cylinder 60. The measured ring 62 is configured to move integrally with the drive shaft 59 by the pin 64.
Is detected by the sensor 63 for detecting the engagement position when is at the fitting position.

The rotary encoder 53 is an optical type,
A magnetic type and a brush type can be used. In either method, the number of output pulses generated during one rotation of the shaft of the rotary encoder 53 is predetermined, and therefore the number of rotations of the drive shaft 59 is calculated by counting the number of output pulses within a fixed time. can do. The rotation of the drive shaft 59 is not limited to the rotary encoder 53. For example, an impeller with a slit is fixed to the drive shaft 59, and the slit is detected by a photo sensor or the like to detect the rotation of the drive shaft. The rotation of 59 may be detected.

The bar code reading / inspection device 70 is a device for reading the information of the bar code 41a printed on the data board 35 and comparing it with predetermined information for inspection, and as shown in FIG. It is composed of a mechanism 71, a reflection type photo sensor 72, a bar code reader section 73, a control section 74 and a RAM 75. In the spool drive mechanism 71, the drive shaft 59 has the key groove 3 of the spool 13.
6 is arranged so as to be slidable between an engaging position for engaging 6 and a retracting position for withdrawing from it, and includes the inspection drive unit 54, the rotary encoder 53, and the motor 76 described with reference to FIGS. 6 to 9. It is configured. In addition,
The spool drive mechanism 71 may be arranged so that the drive shaft 59 engages with the key groove 35 on the opposite side of the spool 13.
The motor 76 drives the inspection drive unit 54 so as to rotate in the film feeding direction. The rotary encoder 53 sends the output pulse to the barcode reader unit 73.

The photo sensor 72 detects the binarized pattern signal of the bar code 41a through the opening 42 of the cartridge 11 while the spool 13 is rotating in the film feeding direction, and the binarized pattern signal is detected by the bar code reader unit. Send to 73. The bar code reader unit 73 replaces the binarized pattern signal fetched from the photo sensor 72 with the bar code waveform of one rotation of the spool 13 based on the output pulse waveform of the rotary encoder 53 and sends it to the control unit 74. The control unit 74 compares the captured bar code waveform with the basic bar code waveform stored in the RAM 75 in advance, and outputs a pass if they match and a fail if they do not match. To do. Then, in the case of failure, retry is performed a plurality of times, for example, about three times.
As a method of forming the bar code waveform by the bar code reader unit 73, in addition to forming based on the output pulse waveform of the rotary encoder 53, a timer is provided in the bar code reader unit 73 and a basic waveform obtained from this timer. You may form based on.

The lid member closing torque inspection device 80 measures the torque when the lid member 22 is rotated from the open position to the closed position, and as shown in FIG. 11, the rotary actuator 81, the torque meter 82, and the clutch. Mechanism 83, drive unit 84 for inspection that engages with the shaft 24 of the lid member 22
The shafts are connected in a straight line by a shaft joint 85. These devices 80 are arranged on the slide table 87 provided on the base 86, and the drive shaft 89 of the inspection drive portion 84 is engaged with the shaft portion 24 of the lid member 22 by the drive of the motor 88. It slides between the position and the retracted position to be retracted. The slide table 87 may be moved by a cam system in which the reciprocating motion of the cylinder is transmitted via a cam.

The rotary actuator 81 is rotationally driven within a fixed angle range in which the lid member 22 rotates between the open position and the closed position. This drive is transmitted to the input part of the torque meter 82. The torque meter 82 is a type that displays the amount of strain of a strain gauge built in between the input unit and the output unit as a voltage, and the torque value (g · cm) can be calculated by converting this voltage value. The output portion of the torque meter 82 is connected to the inspection drive unit 84 via the clutch mechanism 83.
Are connected. The clutch mechanism 83 includes the torque meter 8
This is for protecting the torque meter 82 by slipping when an abnormal force acts on the torque meter 2. In this embodiment, the torque value of the torque meter 82 obtained while the rotary actuator 81 rotates by a certain angle is 55 g.
The case of less than or equal to cm is regarded as a pass, and the case of exceeding this is regarded as a failure. Further, reference numeral 90 is an engagement position detecting sensor, which starts measurement of the torque meter 82 based on a signal obtained from this sensor.

The inspection drive unit 84 is provided with the same safety mechanism as described with reference to FIGS. 7 to 9. The drive shaft 89, as shown in FIG. 12 and FIG.
When engaged with the shaft 24, the protrusions 89a provided on the outer periphery serve to transmit the rotation of the drive shaft 89 to the lid member 22.
Since the lid member opening torque inspection device can also be configured with the same configuration as the lid member closing torque inspection device 80 described above, detailed description thereof is omitted here. In the case of this lid member opening torque inspection device, when the drive shaft 89 is engaged with the shaft 24 of the lid member 22, the protrusion 89a provided on the outer periphery transmits the rotation of the drive shaft 89 to the lid member 22. In addition to performing the action, the tip 40a of the lock pole member 40 is pushed outward from the inside of the C-shaped cross section to release the rotation lock of the lid member 22 at the open position.

FIG. 14 shows a spool lock force inspection device 100.
Indicates. This device 100 has a configuration in which the shafts of a motor 101, a torque generator 102, a rotary encoder 103, and an inspection drive unit 104 are connected in a straight line by a shaft coupling 105, and the motor 101, the torque generation unit 102, and The rotary encoder 103 is shown in FIG.
Since it has the same structure as the motor 51, the torque generator 52, and the rotary encoder 53 described in 1., detailed description thereof is omitted here.

These devices 100 are arranged on the slide table 108 provided on the base 107, and the drive shaft 106 of the inspection drive unit 104 is engaged with the key groove 35 of the spool 13 by the drive of the motor 109. It slides between the engaged position to be retracted and the retracted position to be retracted. The motor 101 is driven so as to rotate the spool 13 in the film feeding direction.
The drive mechanism of the slide table 108 is the drive shaft 1
06 may be arranged so as to engage with the key groove 36 on the opposite side of the spool 13.

In this embodiment, the torque generator 102 is set so as to slip between the output portion of the torque generator 102 and the input portion when a torque of 70 g · cm is applied. The rotary encoder 103 detects the rotation of the drive shaft 106. In the inspection, the spool 13 is rotated with a torque of less than 70 g · cm, and if the spool 13 rotates within a certain period of time, it is rejected, and if it does not rotate, it is output as pass.

FIG. 15 shows the inspection drive unit 104. The drive shaft 106 having a diameter that fits into the key groove 35 is provided with a ridge 106a that engages with the key receiving portion 35a on the outer circumference. The inspection drive unit 104 has a built-in safety mechanism that is substantially the same as the safety mechanism described in FIG. 7, and also has a built-in buffer transmission mechanism that gently transmits the drive of the drive shaft 106 to the spool 13. ing. The safety mechanism and the buffer mechanism are composed of a holding cylinder 110, a spring 111, a fixed ring 112 and the like.

The holding cylinder 110 receives a driving force transmitted from the output portion of the torque meter 102, and has a fitting position where the protruding portion 106a fits into the key receiving portion 35a and a retracted position where the spool 13 is retracted in the axial direction. The drive shaft 106 is movably held between them. The pin 113 is provided inside the holding cylinder 110.
The fixed ring 112 to which the rotation of the holding cylinder 110 is transmitted via
Is built in. The fixed ring 112 and the drive shaft 106 are
A spring 111 is connected inside the holding cylinder 110. The spring 111 is a coil spring and biases the drive shaft 106 toward the spool 13. When the protruding portion 106a and the key receiving portion 35a do not match, the spring 111
The drive shaft 106 is moved to the retracted position against the bias of.
At this retracted position, the concave portion 114 formed at the rear end of the drive shaft 106 and the convex portion 11 formed at the front end of the fixed ring 112.
5, the rotation of the holding cylinder 110 is directly transmitted to the drive shaft 106.

After that, when the projection portion 106a and the key receiving portion 35a are aligned by the rotation of the drive shaft 106,
The drive shaft 106 moves to the fitting position by the bias of the spring 111. At this time, the rotation of the holding cylinder 110 causes the drive shaft 106 to rotate.
If it is directly transmitted to the spool 13, a large moment of inertia acts on the spool 13, the spool lock mechanism jumps, and the spool 13 rotates, which may prevent the spool lock force inspection. Therefore, when the drive shaft 106 is in the fitted position, the engagement between the concave portion 114 and the convex portion 115 is released, and the rotation transmitted from the fixed ring 112 to the drive shaft 106 is twisted by the spring 111. Trying to communicate by. That is, when the drive shaft 106 moves to the fitting position, the engagement between the concave portion 114 and the convex portion 115 is released, and the spring 111 is wound and tightened by the rotation of the fixed ring 112.
Since the rotation is not transmitted to the drive shaft 106 while the spring 111 is wound tightly, a large moment of inertia does not act on the drive shaft 106. After the spring 111 is tightened, the fixed ring 11 is
Two rotations will be transmitted to the drive shaft 106.

A ring to be measured 116 is fixed to the outer periphery of the drive shaft 106 in order to make a timing for inspecting the spool locking force. The measured ring 116 is provided in the engagement position detecting sensor 1 when the drive shaft 106 is in the fitting position.
It is detected by 17, and the timing of starting the inspection can be obtained.

Since 3 has the same structure as the torque generator 102 and the rotary encoder 103 described in FIG. 14, detailed description thereof is omitted here.

These devices 120 are arranged on a slide table 127 provided on a base 126, and a drive shaft 130 of an inspection drive section 125 is engaged with a shaft section 25 of a lid member 22 by driving a motor 128. It slides between the engaging position to be engaged and the retracted position to be retracted.

The inspection drive unit 125 has the same structure as shown in FIGS.
The same safety mechanism as described in 1. is provided. And
The drive shaft 130 has the same structure as described in FIGS. 12 and 13, but engages with the shaft portion 25 on the opposite side of the shaft portion 24. Therefore, even if the drive shaft 130 is engaged with the shaft portion 25, the lock of the lid member locking mechanism is not released.
In addition, the drive shaft 130 is formed with a ridge 130 a on the outer periphery that is inserted into the C-shaped cross section of the shaft 25 in order to transmit the rotation of the drive shaft 130 to the lid member 22.

In this embodiment, the torque generator 122 is set so as to slip between the output portion of the torque generator 122 and the input portion when a torque of 80 g · cm is applied. The rotary encoder 123 detects the rotation of the drive shaft 130. In the inspection, the lid member 22 is rotated with a torque of less than 80 g · cm, and the lid member 22 is rotated within a predetermined time.
When is rotated, it is rejected, and when it is not rotated, it is output as passed.

By the way, when the torque generator 122 slips between the output section and the input section, the rotational positions of the shaft of the rotary actuator 121 and the drive shaft 130 are deviated, and the axis of the rotary actuator 121 is the origin at the next inspection. Even if the drive shaft 130 is returned to the position, the drive shaft 130 still has the protrusion 130a.
Does not enter the C-shaped cross section of the shaft portion 25. Therefore,
At the end of the inspection, the drive shaft origin returning mechanism 124 is operated to return only the drive shaft 130 to the origin position.

The drive shaft origin mechanism 124 includes a cam disc 132.
And a cylinder 133. As shown in FIG. 17 to FIG. 19, the cam disk 132 is
Axis 12 of rotary encoder 123 directly connected to 0
It is fixed to 3a. The cylinder 133 presses the cam surface 132a of the cam disk 132 to push the drive shaft 130 back to the original position. At this time, the drive shaft 130 rotates in the direction opposite to the rotation when the rotary actuator 121 performs the lid member locking force inspection. When the drive shaft 130 rotates in the opposite direction, the torque generator 122 slips, and only the shaft between the output portion of the torque generator 122 and the drive shaft 130 rotates. Thus, even if the rotational positions of the shaft of the rotary actuator 121 and the drive shaft 130 are deviated, only the drive shaft 130 can be returned to the origin position.

Next, the operation of the above configuration will be described with reference to FIG. First, assemble the Patrone 11. In the cartridge 11 that has been assembled, the lid member 22 is in the open position. In this state, the spool lock 47 is moved to the retracted position in conjunction with opening the lid member 22 and the rotation lock of the spool is released.

Thereafter, the cartridge 11 is conveyed to the spool rotation torque inspection device 50 shown in FIG. In the spool rotation torque inspection device 50, the motor 58 is operated and the device 50 slides to the engagement position after the patrone 11 has been positioned in a predetermined posture. At this time, when the protruding portion 59a and the key receiving portion 35a do not match, the drive shaft 59 escapes to the retracted position. The motor 51 is constantly rotating, the drive shaft 59 rotates, and when the protruding portion 59a fits into the key receiving portion 35a, the drive shaft 59 moves to the fitting position and is reliably coupled to the spool 13. . At this time,
The measured ring 62 is detected by the sensor 63, and the inspection start timing signal is output. From the time when this signal is obtained, the number of output pulses of the rotary encoder 53 is counted,
The pass / fail judgment is made based on whether or not the number of revolutions within a fixed time has reached a prescribed number of revolutions. In this embodiment, the number of rotations of the motor is 700 to 1000 rpm, so the inspection time can be 0.5 to 0.7 seconds.

The cartridge 11 that has passed the spool rotation torque inspection is conveyed to the bar code reading / inspecting device 70. The cartridge 11 conveyed to the barcode reading / inspection device 70 is positioned in a predetermined posture, as shown in FIG. Then, the spool drive mechanism 71 moves to the engagement position where it engages with the key groove 36, and the drive shaft 59 rotates the spool 13 in the film feeding direction. During this time, the information of the barcode 41a printed on the data plate 30 is read by the photo sensor 72 and compared with predetermined information to judge whether the information is correct or not. In this embodiment, the rotation speed of the motor 76 is 700 to 1000 rp.
Since it is m, the time required for the inspection can be 0.5 to 0.7 seconds.

The cartridge 11 that has passed the bar code reading inspection device 70 is conveyed to the lid member closing torque inspection device 80. The cartridge 11 conveyed to the lid member closing torque inspection device 80 is positioned in a predetermined posture as shown in FIG. After the positioning of the cartridge 11 in the predetermined posture is completed, the motor 88 operates and the device 80 slides to the engagement position. At this time, the ridge 89a and the shaft 24
If the gap of the C-shaped cross section does not match, the drive shaft 89 escapes to the retracted position. Then, the driving of the rotary actuator 81 is started. The drive shaft 89 slightly rotates and the protrusion 89a enters into the gap having a C-shaped cross section, so that the drive shaft 89 is securely connected to the lid member 22. And the drive shaft 8
The sensor 90 outputs a signal for the timing of starting torque measurement at the time point 9 is moved to the fitting position.

When the drive shaft 89 rotates by a predetermined angle by driving the rotary actuator 81, the lid member 22 moves from the open position shown in FIG. 13 to the closed position shown in FIG. Then, the rotary actuator 81
When the torque value of the torque meter 82 obtained during the rotation by a certain angle is 55 g · cm or less, the result is acceptable, and when the torque value exceeds the value, it is not acceptable. This inspection time is 0.5 to 0.
It can be done in 7 seconds. After the inspection, the motor 88
Operates to move the device 80 to the retracted position. At this time, as the drive shaft 89 retracts from the shaft portion 24, the tip 40a of the lock pole member 40 enters into the gap having a C-shaped cross section, and the lid member 22 is locked in the closed position.

The cartridge 11 that has passed the lid member closing torque inspection device 80 is in a state in which the spool lock mechanism locks the spool 13 in association with the rotation of the lid member 22 to the closed position.

The cartridge 11 in which the spool 13 is locked is conveyed to the spool lock force inspection device 100. The cartridge 11 conveyed to the spool lock force inspection device 100 is positioned in a predetermined posture as shown in FIG. After the cartridge 11 is positioned in a predetermined posture, the motor 109 operates and the device 100 slides to the engagement position. At this time, when the protruding portion 106a does not coincide with the key receiving portion 35a, the drive shaft 106
Is moved to the retracted position, and as shown in FIG.
The concave portion 114 of No. 06 and the convex portion 115 of the fixed ring 112 are engaged with each other. At this time, the motor 101 is constantly rotating, which causes the drive shaft 106 to rotate, and when the protruding portion 106a coincides with the key receiving portion 35a, the drive shaft 106 moves to the fitting position and moves to the spool 13. Securely connected. At this time, the sensor 117 detects the measured ring 116 and the inspection is started.

In the inspection, the number of output pulses obtained from the rotary encoder 103 is monitored within a fixed time, and if the spool 13 is rotated, it is rejected, and if it is not rotated, it is output as pass. In this embodiment, the motor 1
Since the rotation speed of 01 is 700 to 1000 rpm, the inspection time can be performed within 0.6 seconds.

The cartridge 11 that has passed the spool locking force inspection device 100 is a lid member locking force inspection device 12
Transported to 0. The cartridge 11 conveyed to the lid member locking force inspection device 120 is positioned in a predetermined posture as shown in FIG. After the cartridge 11 is positioned in a predetermined posture, the motor 128 operates and the device 120 slides to the engagement position. At this time, the protrusion 130
When the distance a does not match the C-shaped cross section of the shaft portion 25, the drive shaft 130 is moved to the retracted position. afterwards,
The driving of the rotary actuator 128 is started.
The drive shaft 130 pivots slightly, and the ridge 130a moves to the shaft 25.
The drive shaft 130 moves to the fitting position and is securely connected to the lid member 22 by engaging with the clearance having a C-shaped cross section. In this engagement, the tip 40a of the lock pole member 40 is attached to the shaft portion 24.
Since the operation is performed on the side opposite to the side that is locked by entering the C-shaped cross-section of the cross section, even if the drive shaft 130 and the shaft 25 are engaged, the lid member 22 remains locked in the closed position. Has become. Then, when the drive shaft 130 moves to the fitting position, the sensor 134 outputs a signal for the timing of starting the inspection.

The inspection is carried out by the torque generator 122 at 80
The lid member 22 is rotated with a torque of less than g · cm, and the number of output pulses output from the rotary encoder 123 is monitored. If the lid member 22 rotates within a certain time, it is rejected, and if it does not rotate, it is output as pass. To do. This inspection can also be performed in 0.5 seconds to 0.7 seconds. Then, after the inspection is completed, the drive shaft 130 is returned to the origin position by the operation of the drive shaft origin returning mechanism 124.

The cartridge 11 that has passed the lid member locking force inspection device 120 is conveyed to the lid member opening torque inspection device. Since this device has the same configuration as the lid member closing torque inspection device 80, as described above, the same members and reference numerals as those described for the lid member closing torque inspection device 80 will be used in the following description.

The cartridge 11 conveyed to the lid member opening torque inspection device 80 is positioned in a predetermined posture as shown in FIG. After the positioning of the cartridge 11 in the predetermined posture is completed, the motor 88 operates and the device 80 slides to the engagement position. This engagement is performed on the side that locks the lid member 22. Then, the ridge portion 89a and the shaft portion 24
Drive shaft 8 if the gap of the cross section of C type does not match
9 moves to the retracted position. Then, the driving of the rotary actuator 81 is started. The drive shaft 89 slightly rotates, and the protrusion 89a enters into the gap of the shaft portion 24 having a C-shaped cross section and pushes the tip 40a of the lock pole member 40 outward to engage the drive shaft 89, as shown in FIG. Thus, the drive shaft 89 moves to the fitting position and securely engages with the lid member 22. Then, when the drive shaft 89 moves to the fitting position, the sensor 90 outputs a signal for the timing of starting the inspection.

When the drive shaft 89 rotates by a predetermined angle by driving the rotary actuator 81, the lid member 22 moves to the open position shown in FIG. Then, when the torque value of the torque meter 82 obtained while the rotary actuator 81 rotates by a certain angle is 55 g · cm or less, it is determined to be acceptable, and when it exceeds this value, it is determined to be unacceptable.
This inspection time can be 0.5 to 0.7 seconds.

The cartridge 11 that has passed the lid member opening torque inspection device is conveyed to the photo film storing step. In the cartridge 11 conveyed in this step, since the lid member 22 is in the open position, it is not necessary to rotate the lid member 22 one by one. In this photographic film storing step, as described in Japanese Patent Laid-Open No. 6-35123, a tongue-shaped guide plate is inserted into the film passage 21, and the photographic film 12 is guided from the rear end side by using this as a guide. Insert the inside of the Patrone 11 and the rear end 1 of the photo film 12.
After engaging the spool 2a with the spool 13, the spool 13 is rotated in the film winding direction so that the photographic film 12 is entirely stored in the cartridge 11. Then, the photographic film cartridge 10 containing the photographic film 12 is finally packaged and shipped after the lid member 22 is rotated to the closed position to shield the inside.

In this embodiment, in the spool rotation torque inspection device 50 shown in FIG. 6, a torque generator 52 connected to a motor 51 applies a constant torque to the spool, and a rotary encoder 53 causes the spool 13 to rotate.
Although it is assumed that the rotation of the spool 13 is inspected, the present invention is not limited to this, and a torque meter may be used to directly detect the torque required to rotate the spool 13.

The apparatus shown in FIG. 21 shows another embodiment of the spool rotation torque inspection apparatus 150, which is used for directly rotating the spool 13 by using the torque meter 152 to which the AC servomotor 151 is connected. The required torque is detected, and the pass / fail judgment is made based on the detected torque. Reference numeral 153 is a shaft joint with a clutch for protecting the torque meter 152. Torque meter 1
The reference numeral 52 is for detecting torque by slipping between the output section and the input section, and therefore the drive shaft 5 connected to the output section
An origin position returning mechanism 154 is provided to return 9 to the origin position after the inspection.

FIG. 22 shows a spool rotation torque inspection device 1
Fig. 60 shows another embodiment of No. 60, in which the torque required for directly rotating the spool 13 is detected by using the motor-equipped rotary load torque meter 161.
21 and 22, those having substantially the same functions as those described in FIG. 6 are designated by the same reference numerals.

In the above embodiment, the bar code reading inspection is performed after the spool rotation torque inspection, but the order is not limited to this in the present invention, and it may be performed anywhere. However, since it is necessary to rotate the spool 13 at the time of the bar code reading inspection, the inspection may be performed in parallel in a process including a drive unit for rotating the spool 13 like the spool rotation torque inspection device 50. If so, there is an advantage that inspection can be performed efficiently.

By the way, in the lid member closing torque inspection device 80 of the above-described embodiment, the torque when the lid member is rotated toward the closed position is measured by using the torque meter 82 which displays the strain amount of the strain gauge in voltage. Then, the quality of the closing torque is determined by whether or not this value is within a predetermined range. However, this device 80 is expensive and cannot be quickly and accurately performed. This is because an expensive measuring device for converting the voltage obtained from the torque meter 82 into a torque value is required. Further, as a result of performing the torque measurement experiment 100 times, the variation in the measured value is 1
It also produced 00 gcm. This can be accurately measured by calibrating (resetting to 0) the torque meter 82 each time, but if calibration is performed for each measurement, the inspection time becomes long.

When the lid member 22 is opened and closed at high speed, the torque value obtained from the torque meter 82 becomes abnormally high due to the influence of the inertia torque at the initial stage of the rotation of the lid member 22. Therefore, in the inspection device 80, it is necessary to exclude the torque value measured at the initial stage of rotation of the lid member 22 and judge pass / fail according to the subsequent torque value.
As a result, for example, when the photographic film cartridge 10 is loaded into the camera, there is a possibility that a claim may occur in which the lid member 22 cannot be opened and closed by the drive shaft on the camera side.

Therefore, FIGS. 23 to 27 show a lid member closing torque inspection device made in view of eliminating such an adverse effect. In this device, a hysteresis type torque generator incorporating a permanent magnet is used in place of the torque meter based on the strain gauge, and the lid member 22 is rotated to a closed position with a predetermined torque to close the lid member 22. Whether the closing torque is good or not is determined by whether or not the position has rotated.

In the lid member closing torque inspection device 170, the rotary actuator 171, the torque generator 172, and the drive shaft 89 that engages with the shaft portion 24 of the lid member 22 are connected in a straight line by the shaft couplings 173 and 174. , These shafts are supported on the slide table 177 by the two bearing portions 176, and the drive shaft 89 and the torque generator 172 are supported.
A rotational position detector 178 is provided between and. These slide the slide table 177 between an engagement position where the drive shaft 89 is engaged with the shaft portion 24 of the lid member 22 and a retracted position where the drive shaft 89 is retracted by a driving means such as a cylinder (not shown). Note that reference numeral 17
Reference numeral 9 denotes a sensor for detecting an engagement position, which detects an abnormality when the engagement is abnormal. The device 170 detects that it has moved to the front end by the sensor 179, and then starts the torque test based on the fitting normal signal obtained from the sensor 179.

The rotary actuator 171 is shown in FIG.
As shown in FIG. 6, rotation is restricted within a range in which the lever 180 provided on the shaft 171a contacts the stoppers 181 and 182. This drive is transmitted to the input part of the Tokule generator 172. The rotation range of the rotary actuator 171 is about 20% wider than the range in which the lid member 22 rotates between the open position and the closed position. The torque generator 172 changes the drive transmitted to the input shaft to a predetermined torque and outputs the same to the output shaft. When a load of a predetermined torque or more is applied to the output shaft, the torque generator 172 is connected between the input shaft and the output shaft. It is supposed to slip.

As shown in FIG. 25, the drive shaft 89 is provided with a lever 183, and its rotation is restricted within the range in which the lever 183 contacts the stoppers 184, 185. This rotation range is set to be the same as the range in which the lid member 22 rotates between the open position and the closed position.
As shown in FIG. 27, the rotational position detector 178 includes a vane plate 186 that rotates integrally with the drive shaft 89, and an open position where the vane plate 186 is detected when the lid member 22 is in the open position. It is composed of a detection sensor 188 and a closed position detection sensor 187 that detects the blade plate 186 when the lid member 22 is in the closed position.
The quality of the closing torque is determined based on the signals obtained from 87 and 188.

The cartridge 11 conveyed to the lid member closing torque inspection device 170 is positioned in a predetermined posture.
After the patrone 11 is completely positioned in the predetermined posture, the cylinder operates to slide the slide table 177 to the engagement position. When the ridge 89a and the C-shaped cross section of the shaft 24 coincide with each other, a signal is obtained from the engagement position detecting sensor 179, thereby starting the torque inspection.

In the closing torque inspection, driving of the rotary actuator 171 is started first. This rotation is in the direction in which the lever 180 rotates from the stopper 182 toward the stopper 181, and at t0 to t1 shown in FIG.
Will be done in time. This drive is performed by the torque generator 172.
28B, the output shaft is driven to rotate with a predetermined torque as shown in FIG. 28 (B).
The drive of this predetermined torque is performed by the lid member 2 via the drive shaft 89.
2 is transmitted.

The torque required for the initial rotation of the lid member 22 is
As shown in FIG. 28C, a torque equal to or larger than the value set in the torque generator 172 is required. Therefore, at the initial stage of this rotation, the torque generator 172 slips between the output shaft and the input shaft, so that the lid member 22 does not rotate or rotates only slightly. After that, the lid member 22 is set to the time t2.
Start rotating from the position. Therefore, considering this amount, the rotation range of the rotary actuator 171 is set to the cover member 22.
The stroke is over the range of. This makes it possible to absorb the inertia torque at the start of rotation of the drive shaft 89, and control whether or not the drive shaft 89 can be opened / closed by driving with a predetermined torque can be performed from the initial stage to the final stage of the rotation of the lid member.

At time t1, the lever 180 of the rotary actuator 171 is stopped by the stopper 181.
And the drive stops. During this rotation, the detection signal obtained from the closed position detecting sensor 187 is monitored, and when the detection signal is obtained, it can be recognized that the lid member 22 has rotated to the closed position, and it is determined to be good.

After the inspection is completed, the cylinder is operated to slide the slide table 177 to the retracted position. During this movement, the drive shaft 89 comes off the shaft portion 24 of the lid member 22. At this time, the tip 4 of the lock pole 40
0a enters the C-shaped cross section of the shaft portion 24, and the lid member 2
2 is locked in the closed position.

By the way, when the cover member 22 rotates toward the open position by a slight amount when the drive shaft 89 comes off from the shaft portion 24, the tip 40a of the lock pole 40 enters the C-shaped cross section of the shaft portion 24. It will not be able to enter and therefore the lid member 22 will not be locked in the closed position. Therefore, in order to prevent this, when the slide table 177 is slid to the retracted position, that is, the drive shaft 89 is moved to the shaft portion 2.
The rotary actuator 171 is further driven to rotate toward the closing position of the lid member 22 so that the lid member 22 does not reversely rotate in the direction of the open position when the lid member 22 is pulled out. At this time, the drive shaft 89 is stopped by the stopper 184, but by driving the rotary actuator 171 by the amount of overstroke, a predetermined torque can be continuously applied to the lid member 22 toward the closed position direction. Therefore, the rotation of the drive shaft 89 can be restricted, and the lid member 22 can be reliably locked at the closed position by restricting the rotation of the drive shaft within a certain time from the initial stage of the sliding movement.

When the Hysteris clutch brake is used, it is desirable to further rotate the rotary actuator 171 toward the closing position of the lid member 22. In this case, since the lever 180 is in contact with the stopper 181, the drive shaft 89 does not rotate, but a constant torque can be continuously applied to the drive shaft 89. Further, as the drive shaft rotation restricting means, a brake may be applied by a braking means so that the shaft 171a of the rotary actuator 171 or the drive shaft 89 does not rotate.

When a load is generated on the lid member 22 due to a defective assembly or the like, the torque generator 172 slips between the output shaft and the input shaft. Therefore, the drive shaft 8 together with the lid member 22
9 also stops when it receives a load. After that, the rotary actuator 171 is driven until time t1, and the drive of the rotary actuator 171 is stopped when the lever 180 contacts the stopper 181. During this time,
Since the vane plate 186 is also stopped at the position where the drive shaft 89 is stopped, a detection signal cannot be obtained from the closed position detection sensor 187. In this case, it is judged as a failure.

In this device 170, the original point returning operation is performed while moving the slide table 177 toward the retracted position after the drive shaft rotation is restricted within a certain period of time so as to achieve quickness. This work is performed by the rotary actuator 171 until the lever 180 again contacts the stopper 182.
The rotary actuator 1
The shaft 171a of 71 is returned to the initial position. The rotation range of the rotary actuator 171 is wider than the rotation range of the lid member 22, and the drive shaft 89 is restricted to the same rotation range as the lid member 22 by the stoppers 184 and 185. Therefore, the drive shaft 89 can be reliably returned to the initial position regardless of the rotational position. At this time, the open position detection sensor 1
By monitoring the detection signal from 88, it can be recognized whether or not the drive shaft 89 has surely returned to the origin. The inspection can be performed within 0.25 seconds for each Patrone.

Since the torque generator 172 is of a hysteresis type in which a permanent magnet is incorporated, calibration (0 reset) is not performed for each inspection, and there is no measurement error. Further, the strain gauge type torque meter 82 is weak against vibration,
The torque generator 17 lacks in durability and may be damaged if an abnormal load torque is applied.
If 2 is used, it will not be damaged even if an abnormal torque is applied, the life will be semi-permanent, and the cost can be reduced in terms of maintenance such as repair and maintenance. The lid member opening torque inspection device is also the lid member closing torque inspection device 170 described above.
Using the same configuration as the above, the opening torque inspection can be performed by changing the origin position of the drive shaft 89 and the rotary actuator 171 and changing the driving direction of the rotary actuator 171.

In the spool rotation torque inspection devices 50, 150, 160 of the respective embodiments shown in FIGS. 6, 21, and 22, the cartridge 11 is inspected in a horizontal position with the axis of the spool 13 horizontal. ing. However, since the cartridge 11 is used in a vertically installed state in which the shaft of the spool 13 is vertical when loaded in the camera, the rotation torque under actual usage conditions may not always match the inspection result. possible. This is because when the cartridge 11 is placed vertically, each component moves in the vertical direction (the axial direction of the spool 13) by the amount of play required for assembly, or is bent and deformed to interfere with other members. This is because the rotation torque may increase.

In particular, the spool lock 47 is assembled in a deformed state, and a relatively wide space is provided around the spool lock 47 for smooth operation. Therefore, for example, even if the spool lock 47 has an inappropriate dimensional accuracy,
Depending on the degree of deformation, it can be installed at a predetermined position, and when the cartridge 11 is inspected in a horizontal position, it may not be possible to detect an abnormality. However, when the camera is actually loaded vertically and used, the spool lock 47 is moved toward the display plate 29a (see FIG. 1) by gravity, and a load is applied to the display plate 29a by the size error. In extreme cases, the rotation of the spool 13 may be hindered.

Therefore, in order to prevent such a problem, as shown in FIG. 29, the drive shaft 59 of the spool rotation torque inspection device is connected to the spool 13 in the vertical direction with the cartridge 11 placed vertically. Therefore, it is preferable to inspect the spool rotation torque. By doing so, the spool rotation torque can be inspected in accordance with the actual usage conditions, taking into consideration the influence of gravity.

Bar code reading inspection device 7 of the above embodiment
In the case of 0, one reflection type photo sensor 72 is used for the data board 3
The binary pattern signal of the barcode 41a is detected from the reflected light from the barcode 41a marked 0, and the barcode 41a is inspected from the waveform of the binary pattern signal. By the way, in the reflection type photo sensor for reading the barcode 41a provided on the camera side, it is considered that the position facing the barcode 41a is slightly shifted in the radial direction of the data plate 30 for each camera or each camera. To be Therefore, with the photo sensor 72, the barcode 4
A part of 1a (hereinafter referred to as an inspection area) is irradiated with the inspection light, and the reflected light from the inspection area is received to detect the barcode 4.
Even if 1a is read and the inspection is passed, it is conceivable that a portion that does not pass through the inspection area (non-inspection area) has scratches or spot-like stains due to printing mistakes. In this case, there is a problem that the inspection passes but the photo sensor of the camera cannot read it correctly.

Further, even if the inspection area of the photo sensor 72 of the inspection device is widened to inspect all of the bar code 41a exposed in the reading opening 42, the reflected light from the small scratches or stains may cause damage. It is weaker than the reflected light from the correct bar code 41a other than the above. Therefore, the binarized pattern signal from the photo sensor 72 is almost the same as that of the normal barcode 41a, so that it is impossible to detect a partial scratch or the like of the barcode 41a. Furthermore, by expanding the inspection area, 2
Since the rising and falling edges of the digitized pattern signal become unclear, there is also a problem that an accurate inspection cannot be performed.

FIG. 30 shows a bar code reading inspection device for solving such a problem. The bar code reading inspection device 200 includes a spool drive mechanism 71, a photo sensor unit 201 for reading a bar code, and a microcomputer 202 that judges whether the cartridge 11 is acceptable or not based on the output from the photo sensor unit 201. The microcomputer 202 is connected to the line controller 203 which controls the inspection line, and receives the output pulse from the rotary encoder 53. The spool drive mechanism 71 is as described above.

As shown in FIG. 31, the photosensor unit 201 is composed of reflective first photosensors 210 to seventh photosensors 216. The first photo sensor 210 to the fourth photo sensor 213 are arranged in a row along the radial direction of the data plate 30. The fifth photo sensor 214 is provided so as to be in contact with the first photo sensor 210 and the second photo sensor 211 at a position shifted in the rotation direction of the data plate 30. Similarly, the sixth
The photo sensor 215 includes a second photo sensor 211 and a third photo sensor 211.
The seventh photo sensor 216 is provided so as to be in contact with the photo sensor 212 so as to be in contact with the third photo sensor 212 and the fourth photo sensor 213, and the fifth photo sensor 214 to the seventh photo sensor 216 are data plates. They are arranged in a row along the radial direction of 30.

The photo sensor for reading the bar code of the camera, in order to prevent the photo film 12 pulled out from the photo film cartridge 10 from causing fog, the photo film 12 emits infrared rays having a wavelength which is not sensitive. What illuminates is used. Therefore, each of the photosensors 210 to 217 is used to emit infrared inspection light having the same wavelength as that of the photosensor used in the camera, and the bar code 41a is read under actual use conditions.

Each photo sensor 210 arranged in this way
32 to 216 are shown in FIG. The first photo sensor 210 irradiates the circular first inspection area 210 a with inspection light on the surface of the adhesive label 41, and the first inspection area 210 a.
The reflected light reflected by the barcode 41a in a is received. Then, a photoelectric signal having a signal level corresponding to the intensity of the received reflected light is output. Similarly, the second photo sensor 2
The 11th to 7th photosensors 216 include the second inspection area 211.
The inspection light is radiated into the a to seventh inspection areas 216a, and photoelectric signals having signal levels corresponding to the intensities of the reflected light reflected by the barcodes 41a in the respective inspection areas 211a to 216a are output. The diameter R of each inspection region 210a to 216a is set to 1 mm or less in order to inspect the barcode 41a by minutely dividing it.

The arrangement of the inspection areas 210a to 216a is as follows.
It corresponds to the arrangement of each photo sensor 210-216,
The first inspection area 210a to the fourth inspection area 213a are arranged so that the adjacent inspection areas are in contact with each other, and the data board 30.
Are arranged in a row in the radial direction of the fifth inspection region 214a-
The seventh inspection area 216a includes the first inspection area 210a to the fourth inspection area 210a.
The first inspection area 210a to the fourth inspection area 213a are displaced from the inspection area 213a in the rotation direction of the data plate 30.
And the data plates 30 are arranged in a radial direction shifted by 1 / 2.R.

Thereby, for example, the first inspection area 210a
The portion of the barcode 41a that is not inspected by the first photo sensor 210 and the second photo sensor 211 at the boundary between the second photo region 211a and the second photo region 211a passes through the fifth photo region 214a. Checked at 214. In this way, the portions that cannot be inspected by the first photo sensor 210 to the fourth photo sensor 213a are inspected by the fifth photo sensor 215 to the seventh photo sensor 216, and the portion of the barcode 41a exposed in the reading opening 42 is , And at least one of the seven inspection areas 210a to 216a is passed.

Further, since the inspection area is minutely divided and inspected, even if the scratch or dirt is small, the ratio of the scratch or dirt to the inspection area is large. Therefore, when the scratch or dirt passes through the inspection area. A photoelectric signal having a large signal level change is output from the photosensor corresponding to this inspection area. This makes it possible to detect minute scratches and dirt.

FIG. 33 shows a circuit of the inspection device. First photo sensor 210 to seventh photo sensor 216
Each photoelectric signal from is input to the input port 202a of the computer 202. The computer 202 includes an interface (I / F) circuit 220 and a CPU unit 22.
1 is configured as a main circuit. I / F circuit 220
Is inputted with each photoelectric signal from each photosensor 210 to 216 inputted through the input port 202a and an output pulse from the rotary encoder 53. The I / F circuit 220 compares each photoelectric signal with a threshold voltage and converts it into a binarized pattern signal, and based on the binarized pattern signal and the output pulse, based on the detection of each photosensor 210 to 216. Converted to pattern data. The I / F circuit 220 is a line controller 22 that controls the inspection process.
An inspection trigger for instructing the start of inspection is input from 5 to control the operation.

The pattern data is stored in each photo sensor 210.
~ 216 shows the bar types indicating the black bar 230 and the white bar 231 (see FIG. 32) marked on the barcode 41a detected, the width (angle) of each bar 230, 231 and the arrangement thereof. . Therefore, when the normal bar code 41a is inspected, the pattern data is the bar code 4
1a has the same bar type, angle, and arrangement as the bar code 41a, but if the bar code 41a has a scratch or the like, the pattern data converted from one of the photoelectric signals is the bar type, angle. ， The array is wrong. The pattern data thus converted is sent to the CPU unit 221.

The CPU unit 221 has a CPU 221a.
And a RAM 221b connected to this and the RAM 221b as main circuits. The RAM 221b includes the line controller 225 to the interface 226 (for example, RS-232).
Correct pattern data (hereinafter referred to as reference pattern data) of the barcode 41a input via C) is written. The writing of the pattern data is performed only when the information of the barcode 41a to be inspected is changed.

The CPU 221a compares the seven pattern data from the I / F circuit 220 with the reference pattern data. If all the pattern data match the reference pattern data, the CPU 221a passes the test pattern data. 1 of
If even the individual pieces do not match the reference pattern data, it is determined as a failure. The result of the pass / fail judgment is the I / F circuit 2
It is sent to the line controller 225 via 20.
The patrone 11 which is determined to be passed is transported to the next inspection. If it is judged as rejected, it is discharged from the NG gate. It should be noted that the inspection may be retried a plurality of times, for example, three times after it is determined to be unacceptable, and the cartridge 11 that is also determined to be unacceptable after the retry may be discharged from the NG gate. Further, the conversion into pattern data and the determination of pass / fail are processed in real time after the inspection is started.

Next, the operation of the bar code reading / inspecting device configured as described above will be described. Prior to the inspection, the reference pattern data corresponding to the cartridge 11 to be inspected is transferred from the line controller 203 to the computer 2.
02, and this is written in the RAM 221b.
The cartridge 11 conveyed to the bar code reading / inspection device 200 is positioned in a predetermined posture, and then the drive shaft 5
At 9, the spool 13 is rotated in the film feeding direction,
Along with this, the data plate 30 is rotated. At this time, the rotation speed is 1000 r in order to shorten the inspection time.
pm or more. In addition, each photo sensor 210-2
When 16 is turned on, an inspection trigger is input and I
The / F circuit 220 starts to operate.

When turned on, each photosensor 210-216 irradiates the inspection light into each inspection area 210a-216a, and the photoelectric level of the signal level corresponding to the reflectance of the bar code 41a in each inspection area 210a-216a is increased. Output a signal. For example, when there is a white bar 231 having a high reflectance in the first inspection area 210a, the intensity of the reflected light becomes strong and a photoelectric signal of a high signal level is generated by the first photosensor 210.
If there is a black bar 230 that has been output from, and has a low reflectance, the intensity of the reflected light becomes weak and a photoelectric signal of a low signal level is output.

The photoelectric signals from the photosensors 210 to 216 are transferred to the I / F circuit 22 via the input port 202a.
Sent to 0. Each photoelectric signal obtained by one rotation of the data plate 30 is converted into a binary pattern signal by the I / F circuit 220, and then the binary pattern signal and the output pulse from the rotary encoder 53 Is converted into pattern data of type, angle, and array. Therefore,
The pattern data is created for each of the seven inspection areas 210a to 216a. Then, these pattern data are sent to the CPU unit 221 and compared with the reference pattern data.

For example, the bar code 41 free from scratches, stains, etc.
When a is inspected, each photo sensor 210-216
Outputs a photoelectric signal having a signal level corresponding to the correct pattern of the barcode 41a, the reference pattern data and the seven pattern data match. Therefore, in this case, the CPU 221a determines that the result is acceptable,
This judgment result is sent to the line controller 225. Then, the cartridge 11 is sent to the next inspection step.

When the bar code 41 has scratches or stains, at least seven inspection areas 210a-2 having scratches or the like are present.
It will pass any one of 16a. For example,
If there is a scratch 235 in which a part of the black bar 230 is not printed at the position shown in FIG.
5 passes through the sixth inspection area 215a. Accordingly, when the original black bar 230 passes through and outputs a low photoelectric signal level from the sixth photo sensor 215, the scratch 23 is generated.
5, the photoelectric signal of higher signal level is output.

Therefore, this sixth photo sensor 215
The pattern data obtained from the photoelectric signal from
The width of the black bar 230 with 5 becomes narrower than the original width. Of course, the white bar 231 adjacent to this scratch 235
Is wider than it was originally. Further, from the photoelectric signals obtained from the other photosensors 210 to 213, 214, and 216, six pattern data corresponding to the correct barcode 41a can be obtained.

When the seven pattern data thus obtained are compared with the reference pattern data in this way, the pattern data obtained from the sixth photosensor 215 do not match, so that the cartridge 11 fails. Therefore, it is discharged from the NG gate.

Further, as shown in FIG. 35, a white bar 231
Minute stains on a part of the ink (for example, ink attached during printing)
If there is 236, the dirt 236 causes the white bar 236 to be in the inspection area, that is, the second inspection area 21 in the illustrated example.
When passing 1a, the signal level of the photoelectric signal of the second photo sensor 211 changes from a high state to a low state and then to a high state again. Therefore, when this photoelectric signal is converted into pattern data, the pattern data, which should be originally expressed as one white bar, becomes a black bar arranged between two narrow white bars. Therefore,
It no longer matches the reference pattern data and is judged to be unacceptable. It should be noted that it is possible to detect the case where there is white stain in the black bar or the scratch in which a part of the black bar is projected on the white bar. Of course, barcode 41
Needless to say, even when the cartridge 11 having a different pattern a is inspected, the cartridge 11 is discharged from the NG gate.

In this way, the portion of the bar code 41a exposed in the reading opening 42 is divided into the inspection areas 2
A bar code 41 that can be read by inspecting 11a to 216a so that at least one of them passes.
Even if there are scratches or dirt on any position of a, these are detected,
This cartridge 11 can be rejected.

In the above embodiment, each photoelectric signal is converted into pattern data and compared with the reference comparison data. However, the binarized pattern signal is compared with the set signal waveform to judge the pass / fail. You may do it. Further, the number of photosensors and the arrangement of the inspection areas are not limited to the above. For example, the inspection areas may be arranged in a line while being radially offset from the rotation direction of the data plate 30. Furthermore, the inspection areas may be arranged so as to partially overlap each other.

In the above embodiment, the lid member locking force inspection is performed after the spool locking force inspection. However, the present invention is not limited to this, and the spool member locking force inspection is performed after the lid member locking force inspection. The third step may be performed after the fourth step described in 1. According to this, the drive shaft of the lid member locking force inspection device engages with the shaft portion 25 on the opposite side of the shaft portion 24 of the lid member 22 with which the drive shaft of the lid member closing torque inspection device engages. The lid member locking force inspection device can be installed in the same process as the member closing torque inspection device, which shortens the transportation time and saves space on the inspection line. Further, not only for inspection, but also as a mechanism for opening and closing the lid member 22 without causing deformation or bending of the C-shaped section of the shaft portion 24 of the lid member 22, it can be used in other steps.
