Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film for correcting the curl of a photographic film that occurs when the photographic film is stored in a patrone that accommodates the photographic film wound in layers around the axis. A curl correction device.

[0002]

2. Description of the Related Art A negative film that has been photographed is loaded in a state of being housed in a cartridge, and the negative film is pulled out from the cartridge and processed for development, and the entire pull-out from the cartridge is detected. In a developing device for so-called strips processing in which the end of a negative film is cut and processing is continued, a guide member called a short leader is attached to the leading end portion of the negative film, and while the short leader is guided and conveyed, development processing and Photosensitized. In this strips process, the leading edge of the negative film is freed from the curl due to the short leader.
The negative film has the strongest curl in the lowermost layer (that is, the end portion) when wound on a spool. Therefore, if the curl has a loop shape, this loop is crushed by the roller, and the negative film is It may be bent.

In particular, in recent years, it has been proposed to rewind the negative film that has been subjected to the development processing, onto the cartridge and return it to the customer. In this case, by rotating the spool shaft for accommodating the negative film, so-called bellows can be easily carried out. In the case of requesting additional printing, this cartridge is loaded into the printing apparatus and the printing process is carried out.

The negative film wound on such a cartridge has a stronger winding tendency at the terminal end thereof.

It has been considered that a negative film is accommodated in a small cartridge in accordance with the miniaturization of the camera. In such a small cartridge, the curling tendency becomes strong similarly to the above.

For this reason, it is conceivable that the curl habit such as attaching the short leader to the rear end portion of the negative film is corrected in advance and the developing process is performed. However, it must be handled in a state with a strong curl during the baking process.

In order to eliminate this curl, the negative film is once drawn out from the cartridge, and the negative film is heated while being bent in the direction opposite to the curl during the drawing to correct the curl. It has been proposed (Japanese Patent Application No. 4-99448).

Generally, a drum is applied in a state of being bent in a direction opposite to the curl of the negative film. A pair of flanges is formed on the drum to stably convey the negative film, and the negative film is guided and conveyed by the pair of flanges.

In order to reduce the axial torque of the drum and to accommodate the heating means in the drum, it is preferable to bring the driving roller into contact with the outer periphery and rotate it by driving the driving roller.

If dust adheres to the peripheral surface of the drum, especially the surface around which the negative film is wound, the negative film may be damaged or stable heat treatment may not be possible. Therefore, it is considered that the peripheral surface of the drive roller is made to have an adhesive force to remove (adhere) the dust adhering to the peripheral surface of the drum according to the rotation of the drive roller. When a predetermined amount of dust has been removed from the drive roller, this drive roller may be replaced.

However, since the driving roller has the flange formed on the drum, a part of the driving roller is housed in the space between the flanges, and the drum must be detached during the replacement work when a predetermined amount of dust is removed. And the workability is poor.

In consideration of the above facts, the present invention provides a photographic film curl correction device which can be easily attached / detached to improve maintenance workability without interfering with a member for removing dust. That is the purpose.

[0013]

SUMMARY OF THE INVENTION According to the invention described in claim 1, the curl of the photographic film caused when the photographic film is stored in a patrone containing the photographic film wound in layers around the spool axis is generated. A photographic film curl correction device for straightening, wherein a loading section in which the cartridge is loaded, and a photographic film pulled out from the cartridge loaded in the loading section are guided between a pair of flanges to the cartridge. A heat roller for heating the wound photographic film by heating the wound surface by a heating means so as to be in a direction opposite to the winding direction, and a part of the heat roller is housed between a pair of flanges of the heat roller. And a first roller having an adhesive force for adhering dust adhering to the peripheral surface of the heat roller in contact with the peripheral surface of the heat roller, and arranged between the pair of flanges. It has a dust removing means for removing an adhesive to dust the first roller, the.

According to a second aspect of the present invention, the dust removing means is constituted by a second roller which is in contact with the peripheral surface of the first roller and has a stronger adhesive force than that of the first roller. The second roller is characterized in that it is detached by moving it in the axial direction.

[0015]

According to the invention described in claim 1, the photographic film wound around the shaft of the cartridge has a curl. The longer this state is, the stronger the curl is. In particular, the trailing end portion is greatly curled, which causes conveyance failure in a splicer, a developing machine, a printer, or the like. Therefore, a cartridge is loaded in the loading section, the photographic film is pulled out, bent in a direction opposite to the curl and wound around a heat roller, and heated. Thereby, the curl can be corrected.

Here, dust may adhere to the peripheral surface of the heat roller. If this dust adheres, the negative film may be damaged during winding the negative film, or the negative film may not be uniformly heated, resulting in local deformation or uneven density. Therefore, the peripheral surface of the heat roller can be kept clean by adhering this dust to the first roller. here,
The dust adhered to the first roller increases with time, and it is necessary to remove this dust.

By the way, since the first roller is partially housed between the pair of flanges of the heat roller,
It cannot be removed easily. Therefore, in the invention of claim 1, the dust removing means removes the dust adhering to the first roller. The dust removing means can be attached and detached without interfering with the heat roller and the first roller. Therefore, when a predetermined amount of dust is accumulated in the dust removing means, replacement and cleaning work can be facilitated.

According to the second aspect of the present invention, the dust removing means is composed of the second roller which rotates together with the first roller in contact with the peripheral surface of the first roller. The peripheral surface also has a strong adhesive force of the first roller, and the dust adhered by the first roller can be removed by the second roller. Therefore, no dust remains on the peripheral surface of the heat roller and the peripheral surface of the first roller.

Further, since there is no member (for example, a flange of the heat roller) that interferes with the second roller in the axial direction, it is not necessary to attach and detach the heat roller and the first roller at the time of attaching and detaching work. , Workability is improved.

It is supposed to be supported by 4.

When the support shaft 24 rotates, the cylinder portion 16 is rotated in a state of being housed in the cylinder loading portion 18. A lock lever (not shown) is provided at the tip of the support shaft 24. By operating the lock lever while the cylinder portion 16 is housed in the cylinder loading portion 18, axial movement of the cylinder portion 16 is blocked. It has become so.

On one end surface of the cylinder portion 16, ten cartridge loading grooves 26 are provided at the same radial position around the axis, and they are evenly arranged.

The wall forming the inner periphery of the cartridge loading groove 26 has substantially the same shape as the outer periphery of the cartridge 12, and a guide passage 28 for passing the negative film is tangentially formed from a part of this wall. It is provided. This guideway 28
The negative film 20 is extended to the outer circumference of the cylinder portion 16 and can be sent to the outer circumference of the cylinder portion 16 from the negative film 20 drawn from the cartridge 12 loaded in the cartridge loading groove 26.

As shown in FIG. 4, a gear 30 is attached to the bottom of the cartridge loading groove 26, and the shaft portion 30A of the gear 30 and the spool shaft 12A of the cartridge 12 are fitted to each other. There is. By rotating the gear 30, the spool shaft 12A is rotated and the negative film 20 can be pulled out from the cartridge 12.

As shown in FIG. 10A, a circular groove 110 having a diameter smaller than the external dimensions of the cartridge 12 is formed at the bottom of the cartridge loading groove 26, and the circular groove 110 is further formed.
A through hole 112 is provided at the bottom of the. Through hole 11
The peripheral edge of 2 extends in the direction of the cartridge loading groove 26, whereby a cylindrical portion 114 is formed in the circular groove 110.

Inside the cylindrical portion 114, an intermediate portion of the shaft portion 30A is axially supported via a collar 116. As a result, the shaft portion 30A is rotatable as described above and is also movable in the axial direction.

A male screw is formed at the tip of the shaft portion 30A in the direction of the cartridge loading groove 26, and washers 118 and 120 having a larger diameter than the shaft portion 30A are inserted. A nut 122 is screwed onto the male screw, whereby the washers 118 and 120 are fixed.

The shaft portion 30A has a compression coil spring 124 between the bottom portion of the circular groove 110 and the washer 118.
Is installed. The shaft portion 30A is axially moved in the direction of the cartridge loading groove 26 by the biasing force of the compression coil spring 124. In addition, this movement amount is
The gear 30 is restricted by abutting the bottom of the circular groove 110.

Here, when the cartridge 12 does not exist in the cartridge loading groove 26 (state of FIG. 10A), the tip of the shaft portion 30A is projected into the cartridge loading groove 26. However, when the cartridge 12 is loaded into the cartridge loading groove 26, the movement of the cartridge 12 in the loading direction causes the shaft portion 30A to move toward the bottom of the circular groove 110 against the biasing force of the compression coil spring 124. (Fig. 10
(B) state).

In the cylinder loading groove 26, the cartridge 1
2 is loaded, the patrone pressing lever 1 described later

A cartridge detector 128 is arranged in the. The cartridge detector 128 is composed of a bifurcated photoelectric sensor 132 attached to a bracket 130 and a lever 134 that can be retracted between the bifurcated portions.

The lever 134 is attached so as to project tangentially from the outer periphery of the gear 136, and the rotation of the gear 136 causes the photoelectric sensor 132 to project and retract between the two forks. The gear 136 is biased and rotated by a biasing force of a biasing means (not shown) in a direction in which the lever 134 enters between the two forks. In a normal state, the lever 134 turns off the photoelectric sensor 132 (non-conductive state).
I am trying.

The gear 136 meshes with a gear 140 on which a shaft detecting lever 138 is formed so as to project in the tangential direction.
The tip of the shaft detecting lever 138 has the cylinder portion 16
The position is such that it interferes with the shaft portion 30A in the cartridge loaded state during rotation. Therefore, even if the cylinder portion 16 rotates in the state of FIG. 10A, the shaft portion detection lever 138 and the shaft portion 30A do not interfere with each other, and the position of the lever 134 does not change. However, when the cylinder portion 16 rotates in the state of FIG. 10B, the shaft portion 30A interferes with the shaft portion detection lever 138, and the gear 140 is rotated clockwise in FIG.
In response to this, the gear 136 is rotated counterclockwise, and the lever 134 is disengaged from the fork of the photoelectric sensor 132 (the photoelectric sensor is in the ON state).

With the photoelectric sensor 132 in the on / off state, it is possible to determine whether or not the cartridge 12 is present in the cartridge loading groove 26 passing over the cartridge detector 128.

As shown in FIG. 8, the cartridge pressing lever 126 is attached to each of the cartridge loading grooves 26 (not shown in FIGS. 1 and 3).

The Patrone presser lever 126 has a substantially V shape and its bent portion 126A is axially supported by the cylinder portion 16 via a shaft 142. The shaft 142 supported by the cylinder portion 16 is rotated clockwise in FIG. 8 by the urging force of a torsion coil spring (not shown).

One end of the cartridge pressing lever 126 can be retracted into and out of the opening of the cartridge loading groove 26 by rotation about the shaft 142. Here, in the normal state, since it is located above the opening by the biasing force of the torsion coil spring, the cartridge 12 housed in the cartridge loading groove 26 is pressed from above, and the biasing force of the compression coil spring 124 is resisted. Then, the cartridge 12 can be held in the cartridge loading groove 26.

The other end of the cartridge holding lever 126 extends to the vicinity of the outer circumference of the cylinder portion 16.
The leading edge is a protrusion 144 that is protruded to the front side of the paper surface of FIG.
Are formed.

The projecting portion 144 corresponds to the pressing release mechanism portion 146 shown in FIG. As shown in FIGS. 7 to 9, the pressing release mechanism portion 146 is attached to a lid body (not shown) provided on the cylinder portion 16 via a bracket 148.

The pressing release mechanism section 146 is composed of a substantially L-shaped release lever 150 and a substantially Y-shaped limiting lever 152, and their bent portions are coaxially supported by a shaft 154. .

A notch 156 is provided at one end of the release lever 150 and at the center in the width direction, and a hook 158 corresponding to the protrusion 144 of the patrone holding lever 126 is accommodated therein. The hook 158 is the shaft 1
The release lever 150 is pivotally supported by one end of the release lever 150.

A circular hole 162 is provided at the other end of the release lever 150, and one end of the first tension coil spring 164 is locked. The other end of the first tension coil spring 164 is locked to the vertical wall portion 148A of the bracket 148, so that the release lever 150 causes the shaft 154 to move.
The configuration is such that it is rotated clockwise around FIG.

On the other hand, in the limit lever 152, a stopper shaft 166 is attached to a first fin 152A extending along the end of the release lever 150 to which the hook 158 is attached, and the release lever 150 is provided with the stopper shaft 166. The amount of biasing rotation by the first tension coil spring 164 is limited.

The position of the stopper shaft 166 is such that the second fin 152B extending in the diametrical direction with respect to the first fin 152A in the counterclockwise direction in FIG.
Stopper plate 148B formed by bending from 48
Is restricted by abutting against. Also, the first
Release lever 15 to which the tension coil spring 164 of FIG.
The second extension coil spring 168 is provided at the tip of the third fin 152C extending in the diametrical direction with respect to the other end portion of 0.
One end of is locked. This second tension coil spring 1
68 has a biasing force set to be larger than that of the first tension coil spring 164.

Therefore, the release lever 1 which is in contact with the stopper shaft 166 by the urging force of the first tension coil spring 164.
The movement of 50 is restricted by the biasing force of the second tension coil spring 168, and the rotation in the clockwise direction of FIG. 7 is restricted.

The pressing release mechanism section 146 having such a configuration
The lid 158 is arranged on the cylinder portion 16 so that the hook 158 can move the patrone holding lever 126.
It is arranged on the movement locus of the protruding portion 144 (due to the rotation of the cylinder portion 16).

For this reason, as shown in FIG.
When the 44 and the hook 158 are not interfered with each other, the patrone pressing lever 126 moves the patrone loading groove 26.
When the protrusion 144 and the hook 158 interfere with each other as shown in FIG. 9, the cartridge holding lever 126 is rotated about the shaft 142 in the counterclockwise direction of FIG. The pressed state of can be released.

When the release lever 150 interferes with the cartridge 12 protruding from the cartridge loading groove 26, the release lever 150 resists the urging force of the second tension coil spring 168, and the release lever 150 rotates about the shaft 142. Since it rotates in the clockwise direction, damage to the cartridge 12 is avoided. When the cylinder portion 16 rotates in the opposite direction, the release lever 15 is resisted against the biasing force of the first tension coil spring 164.
0 rotates counterclockwise around the shaft 142,
The pressed state of the patrone 12 by the patrone pressing lever 126 is maintained.

As shown in FIG. 1, a sprocket 32 is coaxially attached to the base of the support shaft 24. An endless belt 34 is wound around the sprocket 32. Further, the belt 34 is a drive shaft 36A of a motor 36 provided adjacent to the cylinder loading portion 18.
It is also wound around the sprocket 38 attached to the. By the driving force of the motor 36, the support shaft 2
4 is rotated so that the cylinder portion 16 can be rotated.

The motor 36 is controlled so as to rotate the cylinder portion 16 in steps of 36 °. That is, one rotation (360 °) of the cylinder portion 16 is rotated at each angle divided by the number of mountable cartridges 12, whereby the cartridge 1 while the rotation of the cylinder portion 16 is stopped.
The positions of 2 are the same position.

A guide portion 40 for forming a negative film conveying path corresponding to a part of the cartridge 12 at the same position.
Is provided. The negative film transport path formed by the guide portion 40 is adapted to coincide with the guide path 28 formed in the cylinder portion 16. Therefore, the negative film 20 that has been pulled out from the cartridge 12 and guided to the guide path 28 to reach the outer periphery of the cylinder portion 16
Will be delivered to the transport path formed by the guide portion 40.

As shown in FIG. 5, about 2/3 of the upper end of the tip end of the guide passage 28 on the side of the cylinder portion 16 is projected toward the guide portion 40 and is stepped (hereinafter, it is projected. The side is referred to as the tongue portion 28A and the lower portion is referred to as the base portion 28B.).

The negative film 20 pulled out from the cartridge 12 loaded in the cartridge loading groove 26 is formed with a leader portion 20C having a so-called hooked shape at its tip, and this leader portion 20C serves as a guide path 28. Base 28
Corresponds to B.

On the other hand, the guide portion 40 has a stepped portion similar to the guide path 28 in that a portion facing the guide path 28 (about 1/3 of the lower portion in FIG. 5) is projected corresponding to the base portion 28B. (Hereinafter, the protruding side is referred to as the tongue portion 40A, and the upper portion not formed is referred to as the base portion 40B.).

As a result, the tongue portions 28A and 40A are alternately formed on the guide path 28 and the guide portion 40, and the tongue portions 28A and 40A are arranged so as to mesh with each other.

Tongue portion 40A and base portion 40B of the guide portion 40
6 is inclined downwards in FIG. 6, whereby the guideway 2
A step is formed between the base portion 28B on the eighth side and the tongue portion 40A on the guide portion 40 side.

The negative film 20 immediately after being drawn out from the cartridge 12 has a strong curl, and has a base 28.
When it passes B, it is displaced in the thickness direction with respect to the normal transport path (the lower side of FIG. 6).

Here, the tongue portion 28A of the guide path 28 is
The tongue portion 4 of the guide portion 40 interferes with the oblique side 20D of the leader portion 20C and has a role of limiting the displacement in the thickness direction.
OA has a role of receiving the leader portion 20C that passes through the guide path 28 first and making it climb up by sliding on the slope of the tongue portion 40A, although the leader portion 20C has a strong winding tendency. .

That is, these two tongue portions 28A, 40A

It is configured to smoothly deliver to 0.

The gear 30 of the cartridge loading groove 26 positioned at a position corresponding to the guide portion 40 is adapted to mesh with the gear 42 as shown in FIG. The gear 42 is connected to the drive transmission unit 44.

The gear 42 and the gear 30 are composed of the cylinder portion 16
It is configured to mesh by rotating the
If the shaft rotation of both the gear 42 and the gear 30 is stopped, the rotation of the cylinder portion 16 may be impacted at the time of meshing, and the motor 36 may be out of synchronization. Therefore, in this embodiment, the gear 42 is rotated in the negative film winding direction by the driving force from the driving force transmission portion 44 when the cylinder portion 16 is rotated. As a result, the meshing with the gear 30 is smoothly performed, and the step-out of the motor 36 is prevented.

The drive transmission unit 44 includes three sprockets 4
6, 48 and 50, and an endless belt 52 wound around these in a loop shape.

The gear 42 is coaxially fixed to the sprocket 46. Therefore, when the drive belt 52 is driven, the spool shaft 12A is rotated and the negative film 20 can be pulled out or wound up. it can.

The drive transmission section 44 is constructed so as to be driven by the driving force of the motor 54. A gear 56 is attached to a drive shaft 54A of the motor 54, and the gear 56 meshes with a gear 58A of a clutch portion 58. A substantially V-shaped lever 60 is swingably attached to the gear 58A of the clutch portion 58. At both ends of the lever 60,
A shaft 59 is attached to each of the two gears 60A, 61A and 60B, 61 in the axial direction with the friction member 92 interposed therebetween.
B is attached, and gears 60A and 60B mesh with the gear 58A of the clutch portion 58, respectively. The friction member 92 has a role of lowering the rotational torque of the spool shaft 12A and the drum 78 with respect to the rotational torque of the heat roller 62, which will be described later, and when the negative film 20 is applied with a predetermined tension, The gears 60A and 60B and the gears 61A and 61B are relatively rotated.

One gear 61A at the tip of the lever 60
Are selectively meshed with gears 48A and 50A coaxially attached to the sprockets 48 and 50, respectively.

Here, the sprocket 48 and the sprocket 50 have different winding diameters of the belt 52, and when the motor 54 is rotating at a constant speed, the gear 61A and the gear 4 are rotated.
The feed speed of the belt 52 when meshed with the gear 8A is slower than the feed speed of the belt 52 when meshed with the gear 61A and the gear 50A.

When the motor 54 rotates in the normal direction (rotation when pulling out the negative film 20 from the cartridge 12; clockwise direction in FIG. 1), the lever 60 is swung in the direction opposite to the clockwise direction, and the gear 61A is a gear 48A
Are engaged with each other (state shown by the solid line in FIG. 4). In addition, the lever 54 that causes the motor 54 to rotate in the reverse direction (the rotation when the negative film 20 is wound on the cartridge 12 and the direction opposite to the clockwise direction in FIG. 1) is swung clockwise, and the gear 61A is It is adapted to mesh with the gear 50A (state of imaginary line in FIG. 4).

As shown in FIG. 1, a heat roller 62 is disposed downstream of the negative film transport path formed by the guide portion 40. Heat roller 62

The heat roller 62 is provided with a heat source 62A composed of a halogen lamp or the like at the axial center thereof, and the surface thereof is heated by the heat from the heat source 62A.

Driving rollers 64 and 65 are in contact with a part of the outer circumference of the heat roller 62 which is divided into two parts. A sprocket 93 is attached to one end (lower end in FIG. 4) of the rotary shafts of the drive rollers 64 and 65, and an endless belt 66 is wound around the sprocket 93. The belt 66 is wound around a sprocket 58B that is coaxially attached to the gear 58A of the clutch portion 58.
The heat roller 62 is rotated by the driving force of the motor 54.

The rotation speed of the heat roller 62 is constant, and the negative film 20 can be conveyed at a constant speed. Further, the linear velocity V by the heat roller 62 is faster than the feed velocity V ₁ from the spool shaft 12A of the negative film 20 by the shaft 30A rotated via the gear 48A (V> V ₁ ). This speed difference is absorbed by the relative rotation of the gears 60A and 61A by the friction member 92, and the negative film 20 is conveyed while maintaining a predetermined tension state (tension).

The peripheral surfaces of the drive rollers 64 and 65 have a relatively weak adhesive force, and can be removed by the adhesive force with dust adhering to the peripheral surface of the heat roller 62.

Further, dust removing rollers 94 and 96 are in contact with part of the peripheral surfaces of the drive rollers 64 and 65, respectively. The peripheral surfaces of the dust removing rollers 94 and 96 have a relatively strong adhesive force, and can remove dust from the peripheral surfaces of the heat roller 62 attached to the drive rollers 64 and 65.

That is, the dust removing rollers 94 and 96 are
It is possible to indirectly remove dust attached to the peripheral surface of the heat roller 62. Here, the outer shapes of the drive rollers 64 and 65 are the flanges 62 of the heat roller 62 in plan view.
B and 62C, but the dust removing rollers 94 and 96 are separated from the flanges 62B and 62C. That is, when it is necessary to replace the dust removing rollers 94 and 96, the dust removing rollers 94 and 96 can be easily attached and detached by moving the dust removing rollers 94 and 96 in the axial direction along the shaft 98 without removing other parts.

In the vicinity of the drive roller 64, the temperature sensor 6
8 is provided to detect the surface temperature of the heat roller 62. Here, in the control device 70, the surface temperature of the heat roller 62 is feedback-controlled to the heat source 62A based on the detection signal from the temperature sensor 68, and the temperature of the glass transition point (for example, 70 to 80 ° C.) of the negative film 20 or higher. Hold on.

An endless belt 72 is wound around the outer circumference of the heat roller 62 over a half circumference. The belt 72 is formed in a loop shape by a plurality of rollers 74 and is driven according to the rotation of the heat roller 62.

Here, when the negative film 20 reaches the outer circumference of the heat roller 62, it is sandwiched between the heat roller 62 and the belt 72 and wound around the heat roller 62 over a half circumference to form a substantially U shape. It is designed to be transported.

In addition to this, the belt 72 prevents the evaporation of water from the emulsion layer. If the belt 72 is smaller than the film width, the portion not covered by the belt 72 contracts due to dehydration and deforms like a toy. Therefore, it is preferable that the belt width is slightly wider than the film width.

The negative film 20 is heated by being wound around the heat roller 62, but since the surface temperature of the heat roller 62 exceeds the glass transition point of the negative film 20, it is wound around the spool shaft 12A. This is a configuration in which the curl caused by being taken is eliminated.

As shown in FIG. 3, a pair of belts 72 are provided, one having a role of holding the negative film 20 together with the heat roller 62, and the other having a role of reliably receiving the rotational force of the heat roller 62. ing. by this,
Even when the negative film 20 is sandwiched, the belt 72 is rotated with the rotation of the heat roller 62.

The flange 62B formed on the heat roller 62 guides the width of the negative film 20.

A winding portion 76 is provided on the downstream side in the transport direction of the negative film 20 wound around the heat roller 62 and turned in a substantially U shape. The winding unit 76 is provided with a rotatable drum 78, and the negative film 20 delivered from the heat roller 62 is wound around the outer periphery of the drum 78 in layers. A sprocket 78A is coaxially fixed to the drum 78, and an endless belt 80 is wound around the drum 78. The belt 80 is also wound around a pair of sprockets 82, 84 provided so as to sandwich the gear 60B provided at the other end of the lever 60 of the clutch portion 58. Gears 82A and 84A are coaxially attached to these sprockets 82 and 84, respectively, and a gear 61B is selectively meshed with either of them by rocking of a lever 60.

Therefore, the drum 78 is rotated in the winding direction and the unwinding direction of the negative film 20 according to the forward rotation and the reverse rotation of the motor 54.

Here, when the motor 54 rotates forward,
The linear velocity V generated by the rotor 62 is rotated via the gear 82A.
Winding speed V of the negative film 20 by the drum 78
₂Is faster (V <V₂). This speed difference is
Relative rotation of the gears 60B and 61B by the friction member 92.
Negative film 20 is absorbed by rolling and the negative film 20 is in a predetermined tension state.
It will be transported while maintaining the (tension).
On the other hand, when the motor 54 rotates in the reverse direction, the line formed by the heat roller 62
The speed V is applied to the drum 78 rotated through the gear 82A.
Winding speed V of negative film 20₂Faster than
(V> V ₂). This speed difference is also due to the friction member 92.
Absorbed by the relative rotation of gears 60B and 61B
The negative film 20 is in a predetermined tension state (tension).
Will be transported while maintaining.

That is, when the negative film 20 is pulled out (the gear 61A meshes with the gear 48A, and the gear 61B moves to the gear 8).
The relationship between the linear velocity V ₁ due to the spool shaft 12A, the linear velocity V due to the heat roller 62, and the linear velocity V ₂ due to the drum 78 (in the state of meshing with 2A) is V ₁ <V <V ₂ , and the negative film When the coil 20 is wound (the gear 61A meshes with the gear 50A and the gear 61B meshes with the gear 84A when the lever 60 swings), the linear velocity V ₁ by the spool shaft 12A, the linear velocity V by the heat roller 62, and the drum 78 The relationship of the linear velocity V ₂ is V ₁ >V> V ₂ .

As a result, the negative film 20 is conveyed without slack, and a predetermined tension state (tension) is brought about by the relative rotation of the gear 60A and the gear 61A by the friction member 92 and the relative rotation of the gear 60B and the gear 61B. It is transported while maintaining it.

In the middle of the conveying path between the heat roller 62 and the winding section 76, the light projecting section 86A of the sensor 86 and the light receiving section 8 are provided.
6B are arranged so as to sandwich the transport path. The sensor 86 is adapted to detect the perforations 20A provided on the negative film 20, and the controller 70 detects the detected perforations 2A.
Counting 0A. Here, negative film 2
If the length of 0 is constant, the number of perforations 20A is also constant. Therefore, the number counted when the negative film 20 is completely pulled out from the cartridge 12 is stored in advance and compared with the number counted by the sensor 86. By doing so, it is possible to recognize all the withdrawals of the negative film 20.

The rotation direction of the motor 54 is changed from the normal rotation to the reverse rotation by detecting the full withdrawal. By the reverse rotation of the motor 54, the drum 78 is rotated clockwise, and the heat roller 62 is rotated counterclockwise. In this case, the negative film 20 is pulled out from the winding section 78, and passes through the same route as the conveying route when the film is pulled out from the cartridge 12, and then the cartridge 1
The configuration is returned to 2.

A magnetic head 88 is attached to the heat roller 62 side of the sensor 86 in the middle of the conveying path between the heat roller 62 and the winding section 76. In this magnetic head 88, the magnetic recording layer 2 of the negative film 20 is used.
The information recorded in 0B is read and / or the magnetic recording layer 2
Information can be recorded in 0B.

Heat roller 62 and negative film loading section 1
The cool air from the sirocco fan 90 is fed into the conveyance path between the No. 4 and the No. 4 (arrangement position of the guide section 40). The sirocco fan 90 is controlled so as to be driven only when the negative film 20 is returned to the cartridge 12, and the negative film 20 heated by the heat roller 62 is transferred to the cartridge 12 while being cooled by the cold air. Will be returned. By this cooling, the negative film 20 (support) is cooled to the glass transition temperature or lower. This is because if it is not cooled below the glass transition temperature, it will have a curl again when it is housed in a cartridge.

Therefore, the negative film 20 is accommodated in the cartridge 12 in a state in which the negative film 20 has a winding tendency caused by being wound around the heat roller 62.

Since the winding direction around the heat roller 62 and the winding direction around the spool shaft 12A of the cartridge 12 are opposite to each other, the negative film 20 rewound around the spool shaft 12A is the spool shaft. The winding habit is offset by the winding on 12A.

As described above, when all the negative film 20 is pulled out from the cartridge 12 and the winding is finished again,
The motor 36 is driven to rotate the cylinder portion 16 by 36 °, and the same work is repeated for the next cartridge 12. As a result, the winding habit of the 10 shafts 12 is corrected by the spool shaft 12A, the cylinder portion 16 is removed, the cartridges 12 are removed, and the cartridges 12 are conveyed to the next step (for example, development processing and baking processing). .

The operation of this embodiment will be described below. The cartridge 12 is loaded into each cartridge loading groove 26 of the cylinder portion 16 removed from the cylinder loading portion 18. At this time, the patrone pressing lever 126 is retracted from the opening of the patrone loading groove 26. The shaft portion 30A retracts against the biasing force of the compression coil spring 124, and the cartridge 1
2 is completely contained in the cartridge loading groove 26. As a result, by releasing the retraction of the cartridge holding lever 126, the cartridge holding lever 126 is moved onto the cartridge loading groove 26, and the housed state of the cartridge 12 is maintained.

The cylinder portion 16 in which the cartridge 12 has been loaded is accommodated in the cylinder loading portion 18, and the support shaft 2
The lock lever attached to the tip of the cylinder 4 is operated to prevent axial movement of the cylinder portion 16. This completes the loading of the cylinder portion 16.

When the cylinder portion 16 is rotated,
The cartridge loading groove 26 sequentially reaches the cartridge detector 128. At this time, in the state of FIG. 10A, that is, in the state where the cartridge 12 is not housed, the shaft portion detection lever 138 and the shaft portion 30A do not interfere with each other even if the cylinder portion 16 rotates, and the position of the lever 134 changes. There is no change. As a result, the photoelectric sensor 132 is maintained in the ON state, and the absence of the cartridge 12 can be detected.

In the state of FIG. 10B, that is, in the state where the cartridge 12 is accommodated, the cylinder portion 1
When 6 rotates, the shaft portion 30A and the shaft portion detection lever 138 interfere with each other, the gear 140 is rotated clockwise in FIG. 10, and the gear 136 is rotated counterclockwise in response to this, and the lever is rotated. Therefore, 134 is disengaged from the fork of the photoelectric sensor 132 (the photoelectric sensor is in the ON state). As a result, the presence of the cartridge 12 can be detected.

In the patrone loading groove 26 in which no patrone is detected, the negative film pull-out and winding operations for correcting the curl are canceled, and the next patrone loading groove 26 is positioned at a predetermined position.

When the cartridge loading groove 26, which is detected as having a cartridge, is positioned at a predetermined position, the gear 30 and the gear 42 mesh with each other.

At this time, since the gear 42 is rotated in the direction in which the negative film 20 is wound, the gear 42 can be smoothly meshed with the gear 30 approaching by the rotation of the cylinder portion 16. As a result, it is possible to prevent step-out due to the meshing shock between the gear 30 and the gear 42 of the motor 36 of the cylinder portion 16, and the cylinder portion 16 can be accurately rotated stepwise at predetermined angles (36 °). The rotation of the gear 42 is preferably slightly higher than the moving speed of the gear 30 according to the rotation of the cylinder portion 16 of the gear 30.

When the motor 54 is normally driven in this state, the lever 60 of the clutch portion 58 is swung counterclockwise, and the gear 61A meshes with the gear 48A. As a result, the driving force of the motor 54 is increased by the sprockets 46, 4
It is transmitted to the gears 42 and 30 through the belts 8 and 50 and the belt 52 to rotate the spool shaft 12A at a low speed in the negative film drawing direction (linear velocity V ₁ ).

As a result, the negative film 20 is pulled out from the cartridge 12, guided by the guide portion 40, and comes into contact with the outer periphery of the heat roller 62. At this time,
The sirocco fan 90 is not operated. Here, when the negative film 20 is transferred from the guide path 28 to the guide portion 40, the negative film 20 has a strong curl, and is moved in the direction (thickness direction) into the gap between the guide path 28 and the guide portion 40. Displacement force works.

However, in this embodiment, since the tongue portion 28A is formed in the guide path 28, the oblique side 20D of the leader portion 20C interferes with the tongue portion 28A and limits the above displacement, so that the displacement amount is reduced. .

The distal end of the leader portion 20C whose displacement amount is reduced passes the base portion 28B of the guide path 28 by a slight displacement, and then moves diagonally downward in FIG. However, since the tongue portion 40A of the guide portion 40 is extended to the movement path of the leader portion 20C and has a slope shape, the tip of the leader portion 20C abuts the tongue portion 40A and slides on the slope surface. Climb up. Thereby, the guide path 2 of the negative film 20
8 and the guide portion 40 are prevented from falling off, and can be smoothly transferred from the guide path 28 to the guide portion 40.

Driving force is transmitted to the heat roller 62 through the belt 66 by the normal rotation of the motor 54, and
Is rotated clockwise (linear velocity V).

The negative film 20 reaching the outer periphery of the heat roller 62 is guided between the heat roller 62 and the belt 72.
It is wound half way around in a state where it is sandwiched by 2 and is in contact with the outer circumference of the heat roller 62.

In this case, the heat roller 62 has a collar 6
Since 2B is provided, there is no meandering of the negative film 20, and the negative film 20 is wound linearly.

Since a pair of belts 72 are provided and wound around the heat roller 62 independently of each other,
On the other hand, even if the negative film 20 is sandwiched, the other is maintained in contact with the heat roller 62. Therefore, the belt 72 can be reliably driven by receiving the driving force of the heat roller 62.

Here, the linear velocity V ₁ of the negative film 20 pulled out from the spool shaft 12A and the linear velocity V of the negative film 20 wound around the heat roller 62 are V ₁ <
Since the relationship is V, no slack is generated, but if it is left as it is, a large tension is applied to the negative film 20. However, in this embodiment, the gear 60A and the gear 61
Since the friction member 92 is interposed between A and A, this speed difference is absorbed by the friction member 92, and the negative film 20 is conveyed while maintaining a predetermined tension.

The surface temperature of the heat roller 62 is detected by the temperature sensor 68 and is maintained at a temperature equal to or higher than the glass transition point (70 to 80 ° C.) by feedback correction (on / off of the heat source 62A). This temperature exceeds the glass transition point of the negative film 20, so that the negative film 20 is wound around the heat roller 62, so that the winding habit due to the spool shaft 12A is eliminated.

The sensor 86 detects the perforations 20A of the negative film 20 which has been conveyed in a substantially U shape by the heat roller 62 and sent out. A detection signal from the sensor 86 is supplied to the control device 70, and the control device 70 counts the number of detections of the perforations 20A.

Further, since the magnetic head 88 is provided near the sensor 86, the information recorded on the magnetic recording layer 20B of the negative film 20 is read or new information is recorded during the transportation. You can

The negative film 20 which is conveyed while the perforations 20A are being counted is once taken up by the winding section 76.
It is wound up on the drum 78 and temporarily stored. In this drum 78, since the gear 61B meshes with the gear 82A, the driving force of the motor 54 is at a linear velocity V ₂ faster than the linear velocity V by the heat roller 62 via the gears 60B and 61B at the tip of the lever 60. It is rotated (V <V
₂ ). As a result, the negative film 20 is conveyed without slack, but if it is left as it is, a large tension is applied to the negative film 20. However, in this embodiment, since the friction member 92 is interposed between the gear 60B and the gear 61B, this speed difference is absorbed by the friction member 92 and is conveyed while maintaining the predetermined tension of the negative film 20. It is wound up on the drum 78.

When the control device 70 determines that the count number of the perforations 20A has reached a predetermined numerical value, the negative films 20 are all in the cartridge 1
It is recognized that the motor 54 is pulled out from the motor 2, and the rotation direction of the motor 54 is changed from the normal rotation to the reverse rotation. Due to the reverse rotation of the motor 54, the drum 78 moves clockwise in the heat roller 62.
Is rotated counterclockwise and the spool shaft 12A is rotated in the winding direction of the negative film 20. Further, the lever 60 is swung, and the gear 61A changes to the gear 50A.
The gear 61B meshes with the gear 84A. As a result, the linear velocity V ₂ of the drum 78 becomes low (V> V
₂ ), the linear velocity V ₁ of the spool shaft 12A becomes high (V
<V ₁ ).

As a result, the negative film 20 is wound in the winding section 7
It is unwound from the drum 78 of No. 6 while maintaining a predetermined tension, and is guided again to the outer circumference of the heat roller 62. Here, in a state of being sandwiched by the heat roller 62 and the belt 72, the heat roller 62 is wound around the semicircle and wound around the spool shaft 12A of the cartridge 12 through the guide portion 40 with a predetermined tension.

At the time of rewinding the negative film 20, the sirocco fan 90 is driven, and cold air is applied to the negative film 20 passing through the guide portion 40. For this reason, it is wound around the spool shaft 12A in the cartridge 12 in a state in which a winding habit generated by being wound around the heat roller 62 is attached. However, this spool shaft 12
Since the curl caused by A and the curl caused by the heat roller 62 are in opposite directions to each other, the curl of the negative film 20 is canceled by being wound around the spool shaft 12A.

The cartridge 12 of the negative film 20 described above.
When the drawing and rewinding are completed, the motor 36 is driven and the cylinder portion 16 rotates 36 °. By this rotation, the next cartridge 12 is made to correspond to the guide portion 40, and the same processing is performed 10 times thereafter.

Further, the patrone loading groove 26 into which the patrone 12 for which the curl correction process has been completed is loaded reaches the installation position of the press release mechanism 146 by the rotation of the cylinder 16.

Here, when the cylinder portion 16 rotates from the state shown in FIG. 8 and the protrusion 144 and the hook 158 gradually approach each other, and the protrusion 144 and the hook 158 interfere with each other, the cartridge holding lever 126 FIG. 9 focusing on the shaft 142
By rotating the cartridge 26 in the counterclockwise direction, the pressed state of the cartridge 26 can be released.

When the pressing state by the patrone pressing lever 126 is released, the patrone 12 is
The projecting state is brought about by the biasing force of the compression coil spring 124 attached to 0A. As a result, it is possible to discriminate between the cartridge before processing and the cartridge after processing at a glance.

Here, the cartridge 12 protruding from the cartridge loading groove 26 may also interfere with the hook 158 by the rotation of the cylinder portion 16. But this hook 1
When 58 interferes with the cartridge 12 protruding from the cartridge loading groove 26, the second tension coil spring 168
The release lever 150 rotates in the clockwise direction around the shaft 142 against the biasing force of, and damage to the cartridge 12 or the hook 158 can be avoided.

The curl correction process is carried out in the normal loading order, but when a cartridge which is to be processed urgently occurs,
The cylinder portion 16 is rotated in the reverse direction, and the cartridge 12 which needs the emergency processing is loaded into the cartridge loading groove 26 which is then positioned at a predetermined position. Thereby, the processing can be performed quickly. Even in such a reverse rotation, the hook 158 and the protruding portion 144 interfere with each other, but the cylinder portion 1
If 6 rotates in the opposite direction, the first tension coil spring 1
The release lever 150 rotates counterclockwise around the shaft 142 against the urging force of the shaft 64, so that the patrone 12 is kept pressed by the patrone pressing lever 126. Therefore, the untreated cartridge 12 does not jump out from the cartridge loading groove 26.

When the negative film 20 is pulled out and rewound 10 times, the cylinder portion 16 is removed from the cylinder loading portion 18, and the cartridge 12 is removed. When the extracted cartridge 12 is conveyed to the next step (for example, development processing or baking processing) in a short period of time and the negative film 20 is pulled out to perform the respective processing, the winding tendency of the negative film 20 due to the spool shaft 12A is reduced. Processing can be done without it. Therefore, since a large curl does not particularly occur at the rear end portion, there is no problem such as uneven development processing,
Further, since the leading end portion does not have a large curl, the negative film 20 can be stably transported.

Here, dust carried by the negative film 12 or dust inside the apparatus may adhere to the heat roller 62. If such dust or dirt adheres, the negative film 12 is scratched. In some cases, stable heat treatment cannot be performed. Therefore, the drive rollers 64, 65 are given a relatively weak adhesive force to remove dust and dirt. Further, the drive rollers 64 and 65 are in contact with the dust removing rollers 94 and 96 having relatively strong peripheral surfaces, and the heat roller 6 removed by the drive rollers 64 and 65.
Adhere the dust on the peripheral surface of 2. As a result, the drive rollers 64 and 65 are free of dust and dirt, and the drive rollers 64 and 65 can always maintain the adhesive force.

On the other hand, the dust removing rollers 94 and 96 need to be replaced when a predetermined amount of dust or the like adheres thereto. However, since the outer shapes of the dust removing rollers 94 and 96 are off from the flanges 62B and 62C of the heat roller 62 in a plan view, even if the dust removing rollers 94 and 96 are moved in the axial direction along the shaft 98, no member interferes with them. Without, it can be easily removed.

As described above, in the present embodiment, the device for correcting the curl of the negative film 20 is separate from the developing device and the printing device. The curl can be corrected even before the second baking process.

Further, since 10 cartridges 12 can be loaded at one time and the loaded cartridges 12 will automatically perform work until all curl habits have been corrected, a new work process is added. However, there is no major loss of work efficiency. On the contrary, the workability is improved as compared with the case where the developing treatment or the baking treatment is performed while keeping the curl.

Further, since the linear velocity of the negative film 20 is increased on the downstream side of the conveyance to eliminate the slack, and the predetermined tension is maintained by absorbing the friction member, the linear velocity by the heat roller 62, which is high torque, The negative film 20 is conveyed in accordance with
The heating of the negative film 12 by means of can be made uniform from the front end to the rear end.

By uniformly heating the negative film 12, some damage (change in density, etc.) to the negative film 20 caused by heating is evenly generated in the entire negative film 20, so that there is no problem in practical use.

In order to remove dirt on the peripheral surface of the heat roller 62, the drive rollers 64 and 65 directly contacting the heat roller 62 are made to have a weak adhesive force, and the drive roller 64,
Since the dust removing rollers 94 and 96 having a strong adhesive force are brought into contact with 65, when the dust removing rollers 94 and 96 are exchanged, there is no interfering substance on the axial movement locus, and the dust removing rollers 94 and 96 can be easily attached and detached.

In this embodiment, the cartridge 12 is set to 1
Although 0 pieces of the cartridges 12 are collectively loaded into the cylinder portion 16 and automatically processed, the cartridges 12 may be arranged one by one directly in the vicinity of the guide portion 40.

Further, in this embodiment, the drive rollers 64, 6 are
Each drive roller 6 is used to remove dust from the
Although the dust removing rollers 94 and 96 are provided for the drive rollers 64 and 65, as shown in FIG. The contact position with 65 may be changed.
According to this, the replacement period can be extended.

Further, as shown in FIG. 12, the scraper 102 may be brought into contact with the driving rollers 64 and 65 to scrape off dust and the like adhering to the driving rollers 64 and 65. Further, as shown in FIG. 13, the belt 104 having a strong adhesive force may be driven according to the rotation of the driving rollers 64, 65.

Further, in this embodiment, the tongue piece 28A and the tongue piece 40A are provided on the guide path 28 and the guide portion 40, respectively,
Guide path 28 for the curl of leader 20C of negative film 20
The tongue piece 28A on the side of the guide portion 40 reduces the movement and the tongue piece 40A on the side of the guide portion 40 smoothly guides the leader portion 20C. However, as shown in FIG. You may make it incline in the same direction at an angle larger than the angle.

Further, as shown in FIG. 15, the facing surfaces of the guide path 28 and the guide portion 40 may be formed into a sloped surface having an angle θ in accordance with the angle θ of the oblique side 20D of the leader portion 20C of the negative film 20. At that time, the tip of the guide portion 40 may be lowered in the curl direction from the tip of the guide path 28 (see FIG. 1).
5), the transfer of the negative film 20 becomes smoother.

Further, in the present embodiment, the pressing release mechanism 146 for releasing the accommodation and holding of the cartridge 12 in the cartridge loading groove 26 is arranged above the cylinder portion 16. However, as shown in FIG. The release lever 170 may be arranged in the radial direction of the cylinder portion 16.

As described above, the photographic film curl correction device according to the present invention can be easily attached and detached without interfering with the other members for removing dust to improve maintenance workability. It has an excellent effect that it can be done.
