After the work is completed, the microfilm 204 is rewound into the cartridge 202 again, and the apparatus main body 20
It is separated from 0. During this rewinding, the pulleys 207, 2
08, the drive roller 210, and the belt 209 are retracted to the positions indicated by solid lines.

23 and 24 show a third conventional example.
Reference numeral 500 denotes a cartridge, and a circular reel 501 is rotatably accommodated in the cartridge 500. The microfilm 502 is wound around the reel 501 in a roll shape.

A coupling plate 504 is provided at the center of the reel 501, and the coupling plate 504 is provided with a plurality of locking holes 505 on the same circumference.

Device main body 5 for mounting the cartridge 500
On the 08 side, there is provided a reel drive shaft 503 that reciprocates in the arrow X direction along the axis. A magnet 506 is attached to the center of the end surface of the reel drive shaft 503, and a plurality of locking claws 50 are provided on the same circumference around the magnet 506.

[0024]

However, in the above-mentioned first conventional example, the index label 102 cannot be confirmed with the cartridge 100 mounted in the apparatus main body 103.

As a result, one microfilm 101
However, there is a problem in that the workability is deteriorated when the image information recorded in the above is temporarily copied from a plurality of places.

In the second conventional example, during rewinding,
A space for moving the pulley 208 and the driving roller 210 exists below the guide roller 211. For this reason, the rewound microfilm 204 becomes the guide member 2
When passing through between the guide roller 13 and the guide roller 207a, the joint portion of the leader tape is bent and caught in the space, or its end portion is swung toward the space due to its own weight and rigidity.

As a result, there is a problem that the end portion of the microfilm 204 is caught in the vicinity of the outlet 205 to cause conveyance failure (rewinding failure) or scratch the microfilm 204.

In the third conventional example, the locking claw 507 is used.
And the locking hole 505 are aligned with each other, the reel drive shaft 50
It just reverses 3 once. Therefore, in the case of the cartridge 500 in which the load for starting the rotation of the reel 501 is small, the friction resistance between the locking claw 507 and the coupling plate 506 and the attraction force between the magnet 506 and the coupling plate 506 are combined, so that the reel 501 is a reel. In some cases, the locking claws 507 do not go into the locking holes 505 because they rotate with the drive shaft 503.

As a result, even if the reel drive shaft 503 is rotated in the forward direction, the rotational force is not transmitted to the reel 501, and the microfilm 502 is not drawn out.

The present invention is to solve the above-mentioned problems of the first conventional example. A first object of the present invention is to provide a film transport apparatus capable of reading the contents display section of a cartridge from the outside of the apparatus body while being mounted on the apparatus body. To provide.
Another object is to make the content display unit easy to read. Another object of the present invention is to provide a film transport device that can be easily read by mounting a cartridge. Still another object is to provide a film transport device having a compact structure and easy to read.

The second invention is to solve the problem of the second conventional example, and an object thereof is to provide a film transporting device capable of preventing the film from being bent or shaken when the film is returned to the cartridge. I am trying. Another object is to prevent the film from being bent or shaken with a simple structure.

The third invention is to solve the problem of the third conventional example, and is independent of the reel rotation start load and the frictional resistance between the reel and the retaining claw, and the retaining claw of the reel drive shaft. It is an object of the present invention to provide a film transport device capable of surely inserting the film into the locking hole.

[0033]

In order to achieve the above-mentioned first object, a first invention is an apparatus main body to which a cartridge accommodating a film is attached and detached, and a conveyance for conveying the film in the cartridge attached to the apparatus main body. And a reading unit for reading the content display section of the mounted cartridge from the outside of the apparatus body.

Further, the device body of the first invention is provided with an illumination means for illuminating the content display section.

Further, the illuminating means of the first aspect of the invention has a structure that lights up when the cartridge is mounted in the apparatus main body.

Furthermore, the apparatus main body of the first invention is mounted on an image forming apparatus having an illumination mechanism for illuminating a film, and the light source of the illumination mechanism and the light source of the illumination means are made common.

In order to achieve the second object, a second invention is to provide an apparatus main body for attaching and detaching a cartridge accommodating a film, to which the film is drawn out from an outlet of the cartridge and In the film transporting device provided with the transporting means for returning to the cartridge, the guiding means for imparting the directionality to the film returning to the cartridge is provided in the main body of the apparatus in the vicinity of the outlet of the mounted cartridge.

The guide means of the second invention is attached to the conveying means.

Further, in order to achieve the third object, a third invention is to provide a reel driving shaft with a locking claw to be inserted into a locking hole of a reel wound with a film, and to drive the reel driving shaft from the reel. In a film transporting device configured to rotate forward in order to transport a film, the reel drive shaft is configured to repeat reverse rotation and stop a plurality of times before normal rotation, and the driving force of the reel drive shaft at each reverse rotation is The driving force during the reverse rotation just before was set to be different.

Further, the reel drive shaft is so constructed that its drive force increases as the number of times of reverse rotation increases.

Further, it has a drive source for operating the reel drive shaft to rotate in the reverse direction, and a detection means for detecting the time until the drive source operates a predetermined amount for each reverse rotation, and the operation time of the drive source. In this configuration, the driving force of the driving source for the next reverse rotation is set in correspondence with.

[0042]

According to the first aspect of the present invention having the above structure, the content display section can be read from the outside of the apparatus body by the reading means while the cartridge is mounted on the apparatus body.

Further, if the content display section is illuminated by the illumination means, it can be read more clearly.

When the cartridge is mounted on the main body of the apparatus, the illumination means is turned on to illuminate the content display section.

Further, the light source of the illumination means is common to the light source of the illumination mechanism of the image forming apparatus, and the structure can be simplified.

In the second invention, the film is pulled out from the cartridge and returned by the transporting means. Then, at the time of returning the film, since the guide means gives directionality to the film, the film is regularly returned to the drawing outlet.

Further, since the guide means is attached to the conveying means, the structure is simple.

In the third aspect of the invention, first, the reel drive shaft is repeatedly rotated and stopped a plurality of times by different driving forces. Then, the rising acceleration of the reel drive shaft during reverse rotation changes. Therefore, when the rotation start load of the reel is small,
Even when the frictional resistance between the locking claw and the reel is large, the reel does not rotate, only the reel drive shaft rotates in the reverse direction, and the locking claw is reliably inserted into the locking hole.

After that, the reel drive shaft rotates forward and the film is conveyed from the reel.

Also, since the reel drive shaft has a faster rising acceleration as the number of reverse rotations increases, even if the reel has a small rotation start load or a reel having a large frictional resistance with the locking claws, only the reel drive shaft can be used. Rotates in reverse, and the locking claw is securely inserted into the locking hole.

Further, when the drive source operates, the reel drive shaft rotates in the reverse direction. The detection means detects the time until the drive source operates a predetermined amount. Then, the operating force of the drive source is increased or decreased according to the length of time.

Next, the operation of the above embodiment will be described.

Prior to mounting the cartridge 302, the swing arm 385 is stopped at the initial position biased clockwise. Then, when the cartridge 302 is mounted on the apparatus main body 300, the detection unit detects this and the motor is driven, and the reel shaft engages with the reel 303 and rotates clockwise.

When the drive shaft 380 rotates clockwise, the guide rollers 316 and 317 and the drive pulley 3 are rotated.
18 rotates in the same direction, and the rotation of the drive pulley 318 causes the belt 323 to rotate in the clockwise direction.
0, transmitted to the idler pulley 321. The rotation of the drive pulley 320 is transmitted to the drive roller 324 via the gears 384 and 325, and rotates the drive roller 324 counterclockwise.

On the other hand, the rotation of the drive shaft 380 is transmitted to the swing arm 385 through the roller 387a and the slip mechanism, the swing arm 385 is also displaced to the cartridge 302 side, and the upper end side of the lead-out plate 322 pulls the cartridge 302. Approaching the exit 305.

As a result, the shaft 381 is displaced toward the upper left in the drawing, the link 329 operates counterclockwise by a predetermined angle with the support plate 328 side as a fulcrum, and the film guide 326 moves in the same direction about the shaft 381. Rotate to Figure 13
As shown in (B), the tip is oriented substantially right below. At the same time, the drive roller 324 contacts the microfilm 304 and promotes the rotation of the reel 303.

Then, the leading edge of the microfilm 304 is separated from the reel 303 and enters between the guide roller 306 and the belt 323, and is conveyed rightward in the drawing along the conveying path M.

As the film is conveyed, the microfilm 304 passes between the glass plates 310 and is wound up on the reel 312a which rotates counterclockwise.

On the other hand, at the time of rewinding, the reel shaft rotates counterclockwise, the reel 303 rotates in the same direction, and the drive shaft 380 also rotates reversely.

Microfilm 303 as described above
Is extracted from the cartridge 302 or returned from the cartridge 302 to search for a predetermined image frame, and the image frame is stopped between the glass plates 310. Then, an image frame is illuminated by a lamp (not shown) and projected on the screen, or copied by a printer. After completion of the search, the reel 303 is rotated again counterclockwise, and the microfilm 304 is returned into the cartridge 302 again.

When the microfilm 304 is rewound, the driving roller 324 also rotates clockwise because the belt 323 also circulates counterclockwise. Further, the swing lever 385 operates clockwise by the rotation of the roller 387a and the slip mechanisms 388 and 389, and returns to the initial position and stops.

Then, the upper end side of the swing lever 322 is separated from the outlet 305, and the drive pulley 320 is also displaced to the lower right in the figure as shown in FIG. 13 (A). As a result, the film guide 326 is pushed up by the link 329 and the shaft 38
It rotates clockwise about 1 by a predetermined angle, its tip is directed to the outlet 305 side, and enters the cartridge 302.

Since the conveying path of the microfilm 304 rewound as described above is curved upward near the guide roller 306, the guide member 308 is formed.
The joint portion or the end portion of the microfilm 304 passing between the guide pulley 316 and the guide pulley 316 and 317 tends to bend or swing downward due to its own weight and rigidity, but the film guide 326 is present in the lower space. ..

The motor 634 is a motor for driving 1 and the motor 634 is a motor for driving the pulley 629. The motors 633, 634 and the motor 608 are connected to the control circuit 635.

Further, a detecting means 636 for detecting the mounting of the cartridge 600 is provided in the apparatus main body 601, and the detecting means 636 is connected to the control circuit 635.

In the control circuit 635 of the present invention, when the detecting means 636 detects the cartridge 600, first, the operation of rotating and stopping the drive shaft 609 of the motor 608 in a predetermined angle direction is repeated a plurality of times, and then the arrow V A control program for rotating in the direction is stored. The rotation angle of the drive shaft 609 is detected by detecting the encoder blade 637 attached to the drive shaft 609 by a photo interrupter 648 as a detection unit.

Further, when rotating in the direction of the arrow U,
The voltage applied to the motor 608 is changed so that a driving force different from that at the immediately preceding rotation is generated for each rotation.

Next, the operation of the above embodiment will be described. First, when the cartridge 600 is attached to the apparatus main body 601, the detection means 636 detects this and the motor 608 and the reel drive shaft 607 move to the cartridge 600 side as shown in the timing chart of FIG. Then,
The shaft head 612 contacts the coupling plate 604 by the attraction force of the magnet 613.

At this time, if the pin 614 and the locking hole 605 are aligned, the pin 614 is the spring 6 as shown in FIG. 18 (A).
It is inserted into the locking hole 605 by the elastic force of 16. If there is a mismatch as shown in FIG.

Then, the motor 608 repeats the operation of rotating the drive shaft 609 in the direction of arrow U for a minute time T ₁ and then stopping it for a predetermined time t _{2 a} plurality of times based on the above-mentioned control program. Further, the drive voltage of the motor 608 is made different from the drive voltage immediately before each rotation.

Therefore, the reel drive shaft 607 rotates in the reverse direction,
That is, intermittent rotation and stop in the direction of arrow W are repeated.
Here, if the pin 614 is inserted into the locking hole 605, the reel drive shaft 607 and the reel 604 rotate integrally.

Further, in the state of FIG. 18B, only the reel drive shaft 607 rotates in the direction of the arrow W, and the pin 614 is rotated.
Are inserted into the locking holes 605.

Further, the rotation load of the reel 602 is small, the attraction force of the magnet 613 is strong, the pin 6
When the frictional resistance between the connection member 14 and the coupling plate 604 is large, the reel 602 may rotate together with the reel drive shaft 607. However, in the present invention, the reel drive shaft 6
Since the driving force of 07 is changed, the rising acceleration at the time of reverse rotation is also increased when the driving force is large, and the reel drive shaft 6
07 rotates by itself. Therefore, the pin 614 can be surely inserted into the locking hole 605.

Thereafter, the reel drive shaft 607 is further rotated a predetermined amount in the reverse direction to adjust the winding state of the microfilm 603, and this time, the drive shaft 609 is rotated in the V direction and the reel drive shaft 607 is normally rotated in the arrow Z direction. And microfilm 6
03 is transported to the downstream side.

As described above, in the present invention, the reel 60
Even if the rotation start load of 2 is small and the frictional resistance between the pin 614 and the reel 602 is large, only the reel drive shaft 607 can be rotated and the pin 614 can be reliably inserted into the locking hole 605.
Therefore, the positive rotation force of the reel drive shaft 607 is efficiently transmitted to the reel 602, and the transportability of the microfilm 603 is improved.

A second embodiment of the third invention will be described. In the second embodiment, the drive shaft 609 of the motor 608 is moved to the arrow J
Motor 608 when rotating and stopping in multiple directions.
The voltage applied to the circuit is configured to increase over time as shown in the timing chart of FIG. Other configurations and operations are similar to those of the first embodiment.

According to the second embodiment, the reverse rotation of the reel drive shaft 607 a plurality of times causes the acceleration to increase with time, so that the independent rotation of the reel drive shaft 607 can be further promoted, and the pin 614 and The insertability with the locking hole 605 can be improved.

FIG. 19C is a timing chart showing the third embodiment of the third invention. In the third embodiment, while the encoder 638 measures the rotation amount of the drive shaft, the control circuit 635 detects the time taken until the predetermined rotation amount is reached.

[0122] Then, first to drive the motor 608 at voltages V ₁ to rotate the drive shaft 609 in the direction of arrow U, the time until the output of the encoder 638 is changed is assumed to be T _a, the next rotation time Is applied. That is, if the frictional resistance between the coupling plate 604 and the pin 614 took time T _a with larger voltage V _1, can rotate reel drive shaft 607 faster than this by applying a high voltage V _2.

Then, the time T _b becomes shorter than T _a . Further, next time, a voltage V ₃ lower than V ₂ corresponding to a short time T _b
Is applied, only the reel drive shaft 607 rotates and the pin 6
14 can be inserted into the locking hole 605. Other configurations and operations are similar to those of the first embodiment.

With such a structure, the acceleration force can be adjusted according to the actual magnitude of the frictional resistance between the pin 614 and the reel 604, which is more effective.

For the reference values of time and voltage, values obtained experimentally according to the characteristics of each device are used as the control circuit 6.
It should be set within 35.

[0126]

As described above, according to the first aspect of the present invention, the contents display section can be read from the outside of the apparatus body while the cartridge is mounted in the apparatus body.

Further, if the content display section is illuminated by the illumination means, the readability is further improved.

Further, since the illumination means is turned on when the cartridge is mounted, the workability is good.

Furthermore, since the illumination means of the apparatus main body and the light source of the illumination mechanism of the image forming apparatus are common, the structure is simplified. Therefore, there are effects such as reduction of manufacturing cost, reduction of troubles, and maintenance unnecessary.

According to the third aspect of the invention, the reel drive shaft is independently rotated in the reverse direction regardless of the conditions such as the frictional resistance between the locking claw and the reel and the load for starting the rotation of the reel to lock the locking claw on the reel. Can be inserted securely into the hole.

Therefore, the positive rotation force of the reel drive shaft is efficiently transmitted to the reel, and the transportability of the film is improved.
