Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a microfilm retrieval device for retrieving a desired image from among images recorded on a microfilm. The present invention relates to a microfilm retrieval device equipped with an autoloading mechanism that feeds the microfilm from a cassette reel and winds it onto a take-up reel.

[Prior Art] A league printer has been proposed that can search for a desired image from among images recorded on microfilm, display it, and copy the image if necessary.

In this league printer, a cartridge containing wound microfilm is loaded into the loading section,
The leading end of the microfilm wound on the cassette reel is automatically sent out from the cartridge by a conveyance means, and by so-called autoloading, the leading end passes through an image retrieval device and is wound onto the take-up reel.

In this redubtor, a detector for detecting the presence or absence of microfilm is disposed between the image retrieval device and the microfilm feeding portion of the cartridge, and detects whether or not the microfilm is fed out from within the cartridge. If the microfilm is not detected by the detector, the operation of once rewinding the microfilm to the cassette reel inside the cartridge and sending out the microfilm from the cartridge again is repeated multiple times.

However, if the microfilm cannot be fed out to the take-up reel even after repeating this feeding operation several times, that is, if the tip of the microfilm is not detected by the detector, the transport means for feeding out the microfilm should not be activated. It's stopped.

[Problems to be Solved by the Invention] However, after the microfilm is sent out from the cartridge and detected by the above-mentioned detector, the microfilm is transferred between the detector and the take-up reel or between the image retrieval device. The leading edge of the microfilm may get caught and may not reach the take-up reel.

In this case, the leading end of the microfilm cannot be wound onto the take-up reel. Furthermore, if an attempt is made to send out the microfilm again in this state, there is a risk that the leading end of the microfilm will be damaged.

As described above, in the conventional feeding of microfilm onto a take-up reel, it has not been possible to reliably detect the microfilm and wind it onto the take-up reel without damaging it.

In consideration of the above facts, the present invention is capable of reliably detecting the leading edge of the microfilm during autoloading, and winding the microfilm onto the take-up reel without damaging the leading edge of the microfilm even when autoloading fails. The purpose is to obtain a microfilm retrieval device that can perform the following steps.

[Means for Solving the Problems] In the present invention, a first method detects whether or not microfilm is fed out from the cassette reel and sent to the take-up reel side by the conveyance means after the cassette reel is loaded.
a second detection means arranged downstream of the first detection means in the microfilm transport direction to detect the presence or absence of the microfilm; When the feeding of the microfilm is not confirmed, the microfilm is rewound once to the cassette reel side, and then the microfilm is fed out again to the take-up reel side.If feeding of the microfilm is not confirmed even after repeating the feeding operation a predetermined number of times, it is activated. a control means for controlling the conveying means so as to stop the conveying means, and controlling the conveying means so as to stop the operation if the macro film is not detected by the second detector after being detected by the first detector; It is characterized by being prepared.

[Function] In the present invention having the above configuration, when the IJ-le is loaded into the loading section with the microfilm wrapped in the cassette,
The transport means starts feeding out the leading end of the microfilm from the cassette reel.

The microfilm sent out from the cassette reel is detected by the first detector as being sent out from the IJ-reel, and is further transported by the transport means to the second
After the microfilm is detected by the detection means, the tip is wound around and held on the take-up reel side, and the desired image can be retrieved by winding the microfilm onto the cassette reel and sending it out to the take-up reel. state.

If the leading edge of the microfilm is not detected by the first detector during feeding of the microfilm, the control means operates the conveying means to temporarily sag the cassette reel, rewind the microfilm, and rewind the microfilm again. Feed the film out of the cassette reel. In this case, if the microfilm is not detected by the first detector, this feeding operation is repeated multiple times, and if the leading end of the microfilm is not detected by the first detector, the control means Deactivate the means.

Further, if the microfilm is not detected by the second detector after being detected by the first detector, that is, if the microfilm is clogged between the first detector and the second detector, the control means After activating the means to rewind the microfilm onto the cassette reel, the transport means is deactivated.

[Effects of the Invention] According to the present invention configured as described above, the feeding of the microfilm to the take-up reel side is ensured by the detection by the first detection means.
When the microfilm is not fed out even after repeating the feeding operation of rewinding the microfilm to the cassette reel side and then sending it out again to the take-up reel side up to a predetermined number of times, the operation is stopped and the first If the macrofilm is not detected by the second detector after being detected by the first detector, the operation of the conveying means is stopped, which has the excellent effect of not damaging the leading end of the microfilm.

An endless belt 198 is inserted into a groove provided in the middle of the conveyance roller 196.
is wound around a film damage prevention roller 200 (see FIG. 5) disposed above the conveyance roller 196. This fill major damage prevention roller 200 is pivotally supported by a shaft 204 protruding from a common guide 202. As a result, the rotational force of the conveyance roller is transmitted to the film damage prevention roller 200 by the endless belt 198 and rotated.

Further, as shown in FIGS. 5 and 6, the common guide 202 includes a guide bent to close the gap between the film damage prevention roller 200 and the lower surface of the cartridge 22B loaded in the loading section 26. A section 202A is provided. Further, on the side of the film damage prevention port 202, there is a guide 206 that regulates the width direction of the film transport path.
is attached to the common guide 202.

Therefore, the microfilm 24 fed from the cassette reel 30 is inserted between the endless belt 166, the free rollers 174 and 176, and the conveyance roller 196 while being guided by the film damage prevention roller 200 and the common guide 202.

Furthermore, when the cartridge 22A is loaded into the loading section 26, no gap is created between the film damage prevention roller 200 and the bottom of the cartridge 22A, but when the cartridge 22B is loaded, a gap is created. Although there is a possibility that the leading end of the microfilm 24 may be inserted into this gap, since it can be closed by the guide part 202A of the shared guide 202, there is no possibility that the leading end of the microfilm 24 will be inserted into the gap.

Further, when the cartridge 22A is loaded in the shared guide 202, a notch (not shown) may be provided at the bottom of the cartridge 22A, and the guide portion 202A may be inserted into this notch.

By doing so, when a cartridge with a large opening is supplied and used and loaded into the loading section 26, the gap at the bottom of the cartridge can be reliably closed.

flange roller> In addition, as shown in FIGS. 5 and 6, the drive arm 1
A flange roller 208 is disposed at the bottom of 36. The flange roller 208 and the seven-leaved roller 174.
A guide plate 210 is arranged below 176. The microfilm 24 fed from the cassette reel is guided onto this guide plate 210.

A flange roller 214 having a smaller diameter than the flange roller 208 is disposed on the take-up reel side of the flange roller 208 . The upper part of the flange roller 214 is located above the tip of the guide plate 210. Therefore, the microfilm 24 guided by the guide plate 210 is sent onto the flange roller 214. In conveying this microfilm 24, the flange roller 208.2
Movement of the microfilm 24 in the width direction is restricted by flanges 208A and 214A formed on the microfilm 14. Therefore, the microfilm 24 does not tilt in the width direction around the flange roller 208, and does not move in the width direction.

Further, a guide roller 216 is disposed downstream of the flange roller 214 in the transport direction of the microfilm 24 .

The guide roller 216 is provided at the same height as the small-diameter flange roller 214, and the microfilm 24 is conveyed substantially horizontally when supported by the flange roller 214 and the guide roller 216. Further, a guide roller 220 is arranged above the guide roller 216.

Further, the angle of the microfilm 24 wound around the flange rollers 208 and 214 is set to be at least 10 degrees or more.

<Take-up Reel> As shown in FIG. 4, the take-up reel 28 is rotated by the conveyance of the endless belt 222, with the outer periphery of the endless belt 222 being brought into contact with the microfilm winding section. Endless belt 2
A microfilm 24 is wound up between the microfilm winding section 22 and the microfilm winding section. The endless belt 222 has a driving roller 226 rotated by the driving force of a take-up motor 224.
The take-up reel 28, which is wound around and transported by the driving force of the take-up motor 224, is rotated. In this case, the take-up reel 28 is always pressed toward the axial center by the endless belt 222.

As shown in FIG. 10, the take-up creel 28 has two discs 228 and 230 supported by a fixed shaft 232 facing each other. This fixed shaft 232 has one end supported by the side plate 231 and a side plate (not shown), and has a fixed shaft 232A in the center.
A winding member 234 is supported by a bearing 236 .

Further, a disk support member 238 is supported by a fixed shaft 232B at both ends via a bearing 236. This disc support member 2
Discs 228 and 230 are respectively supported on 38 so as to face each other. Protrusions 228A and 23OA are provided on opposite sides of the discs 228 and 230, respectively,
It has elasticity. The outer periphery of the disc support member 238 corresponds to the lower portions of the protrusions 228A and 23OA, and a slight gap S is provided. This gap S is set to be larger than the thickness of the microfilm 24. Furthermore, the fixed shaft 232B is provided with an outward taper. Therefore, the discs 228, 230 are able to swing relative to the fixed shaft 232B.

The discs 228 and 230 are biased toward each other by a compression coil spring 240. Therefore, the microfilm 2 inserted between the discs 228 and 230
4 is a protrusion 228A provided on the disk 228, 230;
23OA and both sides abut, and when the microphone n film 24 is further pressed by the endless belt 222 toward the winding member 234, the discs 228 and 230 resist the biasing force of the compression coil spring 240 and move away from each other. oscillate. Due to this swinging, both ends of the microfilm 24 in the width direction are separated from the disk support member 238 and the protrusions 228A, 23O.
A, and the middle part in the width direction is the winding member 234.
The macro film 24 is deposited onto the winding member 234 in contact with the macro film 24 .

Detector> The loading drive system for the microfilm 24 configured as described above includes the flange roller 208 and the free roller 1.
74 and 176, a first detector 212 is arranged as shown in FIG. This first detector 21
2 is a flange roller 208 and a free roller 174.17
6 is detected.

Further, between the guide roller 216 and the flange roller 214, there is a third roller corresponding to both ends of the microfilm 24 in the width direction.
A detector 218 is provided.

This third detector 218 is provided at both ends of the microfilm 24 in the width direction, detects blip marks corresponding to the image position on the microfilm 24, and searches the image position when searching for a desired image. . Also, the position of the microfilm 24 in the width direction is at the flange roller 208.214.
Since it is regulated by the law, it can be detected reliably. Furthermore, the flange roller 208 and the flange roller 2
14 and the guide roller 216, the microfilm 24 is always conveyed at the same distance to the third detector 218, so that the blip marks on the microfilm 24 can be reliably detected. The first detector 212 and the third detector 218 are connected to a control device 242 .

Further, a light source 36 for irradiating light onto the image recorded on the microfilm 24 is arranged below the transport path on the downstream side of the guide roller 220 in the microfilm transport direction, and a lens 34 is arranged above.

Further, on the downstream side of the light source 36, a second detector 213 having the same configuration as the first detector is arranged below the microfilm transport path. This second detector 213 is connected to the control device 24
Connected to 2.

As shown in FIG. 11, the control device 242 is connected to a supply motor 172, a solenoid 190, a motor 155, a motor 94, and a pickup motor 224.
The operation of each is controlled.

Next, the search drive system will be explained.

Take-up reel 28 side 8 As mentioned above, the take-up motor 2
The microfilm 24 is rotated by the endless belt 222 conveyed by the endless belt 24 and wound up between the endless belt 222 and the winding member 234.

On the other hand, the driving force of the supply motor 172 is transmitted to the force set reel 60, and the force setting reel 60 is biased in the direction of winding the microfilm 24 onto the cassette reel 60. Therefore, the microfilm 24 is maintained under tension by the supply motor 172 and the pick-up motor 224.

From this state, take up the microfilm 24 onto the reel 2.
By winding the microfilm 24 toward the cassette reel 30 or rewinding the microfilm 24 to the cassette reel 30,
A desired image can be searched from among the images recorded in 4.

Next, the operation of this embodiment will be explained using the timing chart shown in FIG. 12 and the flow chart shown in FIG. 13.

First, the case where the cartridge 22B is loaded into the loading section 26 will be explained, and then the case where the cartridge 22A is loaded will be explained.

In the loading section 26 into which the cartridge 22B is loaded, the auxiliary arm 126 is maintained in a vertical state by a moving plate 156, as shown by the two-dot chain line in FIG. Furthermore, the drive arm 136 resists the biasing force of the torsion coil spring and is on standby at the position shown by the two-dot chain line in FIG.

From this state, the cartridge 22B is inserted into the loading section 26 and detected by a detector (not shown). In this state, the cartridge 22B is compressed by the compression coil spring 1.
The back contact member 110 is brought into contact with the biasing force 16 and is pressed toward the side plate 78. When the cartridge 22B is pressed toward the side plate 78, the motor 94 operates to cause the reel shaft 74 to protrude from the through hole 78A of the side plate 78 (position A in FIG. 12). The head 106 of the abutting member 96 is a semicircular hole 66 with a bottom.
68.

When a predetermined period of time (between A and B in FIG.
Figure B position>. The reel shaft 74 rotates counterclockwise in FIG. 6 by this driving force, rotates the cassette reel 60 in the same direction, and starts winding the microfilm 24.

This rotation also ensures that the engagement pins 106 are inserted into the respective bottomed semicircular holes 66, 68. In the engaged state in which the engagement bins 106 are inserted into the bottomed semicircular holes 66 and 68, the cartridge 22B is held between the back contact member 110 and the contact member 96 by the biasing force of the compression coil spring 102 and the compression coil spring 116. be done.

When a predetermined time (between B and C in FIG. 12) has elapsed, the motor 15
5 starts operating (position C in Figure 12).

The operation of this motor 155 causes the disk cam 154 to move to the sixth position.
In FIG. 6A, it rotates clockwise around the rotation support shaft 153 to move the moving plate 156 to the right side of the paper in FIG. 6A. As a result, the auxiliary arm 126 is inserted into the cartridge 22B through the slit 64 provided in the side wall of the cartridge 22B, and the drive arm 136 is also inserted from inside the opening 62.
contacts the outermost layer of the microfilm 24. Further, the peeling claw 144 also comes into contact with the outermost layer of the microfilm 24.

After a predetermined time period (between C and D in FIG. 12) has elapsed, the solenoid 190 is actuated to swing the conveying arm, the gears 178 and 180 are engaged, and the conveying roller 196 and free rollers 174 and 176 are in contact with each other.Furthermore, the reel The reverse rotation of the shaft 74 is stopped, and the tightening of the microfilm 24 is completed.Thereby, the microfilm 24 is wound tightly inside the cartridge 22B.

At the same time, the driving force of the supply motor 172 is transmitted to the shaft 118 by a clutch (not shown).
position), rotate the pulley 123, and rotate the endless belt 12.
4 is conveyed, and the roller 128 is rotated counterclockwise in FIG. 6 (in the direction of arrow C). Further, the driving force of the drive shaft 170 and the brake motor 172 is transmitted and rotated by a clutch (not shown), and the drive pulley 168 is rotated clockwise in FIG. Rotate. When the pulley 142 rotates, the drive roller 140 is rotated counterclockwise in FIG. 6 by a gear (not shown).

As a result, feeding of the microfilm 24 in the six directions shown by the arrows is started. In this state, the driving force of the supply motor 172 is transmitted by a clutch (not shown), so the free rollers 174, 176 and the conveyance roller 196 are rotationally driven.

On the other hand, the tip of the microfilm 24 wound onto the cassette reel 60 is in close contact with the outermost layer due to static electricity, poor drying, or the like. In this state, the microfilm 24 is driven by the rotation of the roller 128 and the drive roller 140, and the tip of the microfilm 24 comes into contact with the tip of the peeling claw 144. Further, when the microfilm 24 is fed out by the roller 128 and the drive roller 140, the leading end of the microfilm 24 is peeled off from the outermost layer by a peeling claw 144. The peeled tip is a peeling claw 144
The film is guided downward by the guide portion 144B, further guided by the film damage prevention roller 200 and the shared guide 202, and inserted between the free rollers 174, 176 and the conveyance roller 196 (FIGS. 12E-F). The microfilm 24 inserted between the free rollers 174, 176 and the transport roller 196 is fed onto the guide plate 210.

When the microfilm 24 is sent out from within the force↓ trifuji 22B, the leading end of the microfilm 24 is detected by the first detector 212 (position F in FIG. 12).
.

When the first detector 212 detects the microfilm, the motor 155 is activated to move the moving plate 156 to the right side of the paper in FIG.

This movement causes the drive arm 136 and the auxiliary arm 12 to
6 is extracted from the cartridge 22B. Then,
The take-up reel 28 is driven by an endless belt conveyed by a tick-up motor 224 (position G in FIG. 12) and waits for the leading end of the microbuoy film 24 to arrive.

The leading end of the microfilm 24 whose delivery from the cartridge 22B has been confirmed by the first detector 212 is guided by the guide 210 and wound around the flange roller 208. After being wound around the flange roller 208 , the leading end portion of the microfilm 24 is wound around a small-diameter flange roller 214 and then around a guide roller 216 . After being wound around the guide roller 216, the leading end of the microfilm 24 is wrapped around the guide roller 220.
wrapped around. The microfilm 24 whose passage was confirmed by the first detector 212 is transferred to the second detector 213.
detected. The leading end of the microfilm 24 is fed onto the outer periphery of the winding member 234 of the winding reel 28 and is pressed by the endless belt 22 to form the protrusion 228.
It is held between A and 23OA and the winding member 234, and is sequentially wound onto the winding member 234.

When detected by the second detector 213 (position H in Figure 12)
After a predetermined period of time has elapsed, the operation of the solenoid 190 is stopped, and the forward rotation of the supply motor 172 is stopped.

In this state, the take-up reel 28 is connected to the take-up motor 22.
Although the microfilm 24 is trying to rotate with the driving force of 4, since the cassette reel 60 side has stopped feeding, the microfilm 24 remains stationary. After a predetermined period of time has elapsed, the tick-up motor 224 is stopped and the microfilm 24 is in a state where it can be searched. Through the above operations, loading is completed.

Here, from inside the cartridge 22B, remove the microfilm 24 from inside the cartridge 22B.
Supply motor 172 and conveyance roller 1 in case the tip part is not fed out due to static electricity, curling, etc.
The control of 96 will be explained according to the flowchart shown in FIG.

When the cartridge 22B is loaded into the loading section 26, the number of normal rotations of the supply motor 172 is increased to 3 in step 300.
It is determined whether or not the number of times is less than or equal to the number of times. If it is three times or less, the supply motor 172 is rotated in the normal direction in step 302, and the leading end of the microfilm 24 is fed out. Step 3
At step 04, it is determined whether a predetermined period of time has elapsed. If the predetermined time has not elapsed, the supply motor 172 continues to operate. When the predetermined time has elapsed, the first
It is determined whether the leading end of the microfilm 24 has passed through the detector 212, that is, whether the microfilm 24 has been fed out from the cartridge 22B. 1st-
After the tip is detected by the second detector 212, the second detector 213 detects the microfilm 24 in step 308, the supply motor 172 is activated, and after a predetermined period of time, the supply motor 17 is activated in step 310.
2 stops working. In this state, the macro film 24
The tip of the winding is wound onto the winding creel 28,
It is in a searchable state by the search drive system.

When the microfilm 24 is not detected by the second detector 213 in step 308, the supply motor 172 is driven in reverse in step 318. By reversely driving the supply motor 172, the microfilm 24
is wound onto a cassette reel. In this state, the drive of the supply motor 172 is stopped in step 320.

If the leading end of the microfilm 24 is not detected by the first detector 212 in step 306, that is, if the leading end of the microfilm 24 is not fed out from inside the cartridge 22B due to static electricity, curling, etc., the supply motor 172 is driven in the reverse direction, the reel shaft 74 is driven in the reverse direction, and the microfilm 24 is rewound onto the cassette reel 60. In step 314, it is determined whether or not a predetermined period of time has elapsed during the reverse rotation, and when the predetermined period of time has elapsed, the number of times N is counted in step 316.

Then, the process returns to step 300, and it is again determined whether the number of times N of normal rotation operation is 3 or less. When the number of normal rotation operations N exceeds 3, the process proceeds to step 310, where the supply motor 172 is stopped.

As described above, in this embodiment, when the feeding of the microfilm 24 from the cartridge 22B is not confirmed, the operation of rewinding the microfilm 24 to the cassette reel 60 and feeding it out again is performed a predetermined number of times, and the microfilm 24 is detected by the first detector. If the tip portion is not detected by the second detector after the tip portion of 24 is detected,
Since the supply motor 172 is stopped after the microfilm 24 is rewound to the cassette reel, the microfilm 24 is not damaged.

In this embodiment, the operation of rewinding and feeding out the microfilm 24 was performed three times, but the operation is not limited to this and may be performed multiple times.

Furthermore, in this embodiment, the second detector 213 is connected to the guide roller 2.
20, but the present invention is not limited thereto, and it may be placed anywhere downstream of the first detector 212, preferably on the take-up reel side in the transport direction of the microfilm.

Further, in this embodiment, in addition to the first detector, a second detector 21 is used.
3 on the downstream side of the first detector, the tip of the microfilm 24 can be reliably detected, the microfilm 24 is not forced to be fed out, and the second detector
If the microfilm 24 is not detected by the detector 213, the feeding is stopped, so that the microfilm 24 is not damaged.

Furthermore, since the feeding operation is repeated three times, the microfilm 24 can be fed out reliably.

Next, the case where the cartridge 22A is loaded into the loading section 26 will be explained.

When the cartridge 22A is loaded into the loading section 26, the motor 155 is activated to rotate the disc cam 154. As a result, the moving plate 156 moves to the right side of the paper in FIG. 6A. However, since the side wall of the cartridge 22A is not provided with a slit, the contact portion 126 of the auxiliary arm 126
B is pressed by the side wall of the cartridge 22A and the sixth
As shown in the figure, it becomes approximately vertical. At this time, since the contact portion 126B contacts the side wall of the cartridge 22A,
The roller 128 does not come into contact with the side wall of the cartridge 22A.

The drive arm 136 operates in the same manner as when loading the IJ screw 22B, and is inserted into the cartridge 22A through the opening 44 and operated.

Therefore, in the case of the cartridge 22A, the leading end of the microfilm 24 is fed out by the drive roller 140.
This is done by the conveyance rollers 196.

Next, a case will be described in which a desired image is searched from among images recorded on microfilm.

When the order of blip marks corresponding to a desired image is designated, the supply motor 172 is driven to rotate the cassette reel 60 to rewind the microfilm 24, and the tick-up motor 224 is driven to rotate the take-up reel 28. Winding F)! By winding up the microfilm 24 onto the roller 28, the third detector 218 detects the blip mark corresponding to the desired image, and searches for the desired image.
