Abstract

PURPOSE:To securely and smoothly send out a film by guiding the tip of the leader tape out of a cartridge by a reel driving mechanism, and then pressing a feeding means against the leader tape and driving the means. CONSTITUTION:When the tip part of the film F in a 3MM type cartridge is sent out, the tip of the leader tape (f) is guided out by the reel driving mechanism 23 and then the roller 50 of the feeding means is pressed against the leader tape (f) and driven. Consequently, the film F is sent out of the cartridge A securely and smoothly with ease. Namely, when the film is sent out, the tip part (f) of the film abuts on a guide 16, etc., and is caught and charged, so that its jam is eliminated. Further, the tip part (f) of the film is enabled by a simple constitution to rotate in the cartridge without being sent out of the cartridge. Thus, the film is sent out securely and smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a roll film feeding device in the rear section of a roll film key A7 used in a film image projector.

For example, roll film is used in reader printers that can view and copy microfilm images, readers that are only for viewing, etc., and is loaded with a cartridge that stores microfilm wound into a reel. This invention relates to a device that constitutes a carrier section and sends out the leading end of this microfilm to the outside.

"Prior Art" Roll films are broadly classified into 3MM type and ANSI standard type. That is, 3M()Iinn shown in FIG.
esota Mining'&)lanufactu
ring) M type cartridge A and the ANS I (American National ring) shown in FIG.
Standards Institute, Inc.
) Standard type cartridge B refers to the number and structure of connection holes 3 and 4 in reels 1 and U2 stored inside, the corresponding structure of its drive shaft, and The presence or absence of the league depth f and the corresponding delivery structure are largely responsible. Note that the leader tape f is the film Fa and the reel 1.
It is wider and is usually wound around the outer circumference of the reel several times, and is made of a strong and hard material with a thick wall.

The present invention is mainly directed to this 3MM type cartridge A. And for this kind of cartridge A,
The film feeding device of the roll film carrier section is
For example, as shown in Japanese Utility Model Application Publication No. 59-71318, it has conventionally been wide.

That is, as shown in FIG. 7, the conventional film feeding device uses a dedicated feeding roller 5, which is driven two rotations to press against the leader tape f of the film F in the loaded cartridge A, and first, the leader tape f is The tip was guided from the outer periphery of reel 1 to the outside l\\ of the cartridge, and was sent out with it.

``Problems to be solved by the invention'' By the way, such conventional roll film feed lil
When we visited the equipment, the following problems were pointed out.

In other words, as described above, for feeding, the feed roller 5 is pressed against the leader tape f in the outside of the cartridge A near the upstream side of the area facing the feeding opening 7 of the cartridge A. A pressing force is applied to the leader tape f toward the reel 1 side, and the leading end of the leader tape f is also pressed against the reel 1 side. Therefore, the leader tape f
Due to the rotational drive of the feed roller 5, the tip of the reel does not proceed outward along a normal trajectory as shown by the imaginary line in FIG. 7, but tends to proceed along a trajectory biased towards the reel 1 side as shown by the solid line. becomes. Therefore, depending on the curl, the leading end of the leader tape f comes into contact with the leading end of the kite board, causing a so-called jam, such as being pulled, jammed, or stuck. Also, depending on the curl, it may progress more toward the reel 1 side, and the opening 7 of the cartridge A may move toward the reel 1 side.
Instead of being guided to the outside, the reel advances into the cartridge A again, and continues to rotate around the outer periphery of the reel 1, sometimes failing to perform its original function as a feeding device.

Such a problem has been pointed out in the conventional example.

In view of these circumstances, the present invention has been made in order to solve the problems of the conventional methods described above.When feeding the leading end of the film of a 3MM type cartridge, the leading end of the leader tape is moved externally by a reel drive mechanism. It is an object of the present invention to propose a roll film feeding device that can reliably and smoothly feed the film from inside the cartridge by driving the feeding means into pressure contact with the leader tape after the film has been guided to the leader tape.

"Means for Solving the Problems" The technical means of the present invention to achieve this objective are as follows.

This roll film feeding device feeds out a film which is wound into a roll on a reel within a cartridge and has a leader tape at its tip.

It also has the following reel drive mechanism and feeding means.

The reel drive mechanism is connected to the connection hole of the reel, rotates the reel in the direction in which the film is fed out, and guides the leading end of the leader tape to the outside.

The feeding means is arranged so as to be able to press against the leader tape wound around the outer periphery of the reel and the leading end of which is led to the outside by means of a force clamping mechanism, and is rotated by a feeding drive mechanism in a direction opposite to the rotational direction of the reel. It consists of a feed-out roller, etc., which are equally driven.

"Function" Since the roll film feeding device according to the present invention is comprised of such means, it functions as follows.

At the time of feeding, the reel is first rotated in a predetermined direction by the reel drive gate mechanism, and the long film wound on this reel in the form of a roll is rotated in the feeding direction, that is, in the direction in which the outer periphery of the film is unwound.

Then, the leader tape at the leading end of the film is made of a thick, strong and hard material, and there is no pressure contact with the feed roller near the upstream area of the area facing the cartridge feed opening. Therefore, due to its own rigidity, the leader tape leaves the outer periphery of the reel from its tip and travels in a substantially tangential direction, following a trajectory toward the opening of the cartridge. The tip is guided to the outside through the opening.

Next, the drive of the reel drive mechanism is stopped and the reel becomes free, but instead the leader tape is further fed by a feeding means such as a feeding roller.

That is, the feeding means is pressed against the leader tape, which is wound around the outer periphery of the reel and whose leading end is led to the outside by the reel drive mechanism as described above, by its urging member. Moreover, since this feeding means is driven by its feeding drive mechanism to rotate in a direction opposite to the rotational direction of the reel, the reel continues to rotate up to that point.

Then, the leader tape and even the film body are further fed by this feeding means, and the leader tape is conveyed and wound onto a spool.

In this way, the film is fed out from inside the cartridge reliably and smoothly.

"Example" The present invention will be described in detail below based on the example shown in the drawings.

First, the roll film carrier section of the reader printer illustrated in FIG. 4 will be outlined.

A long film F1, for example, a roll film, is wound into a roll on reel 1 in a 3MM type cartridge A or reel 2 in an ANSI standard type cartridge B, which is loaded from the left side in the illustrated position. The type of microfilm is sent out to the outside from its leader tape f or its front end f' by the present roll film feeding device 8.

Then, the sheet-like film F is transported by a feed roller 9 degrees and a roller equipped with an encoder 10 degrees. Plate part 11. Guide roller 12
etc., and then wound onto the spool 13 again.

Then, the film F can be transported in forward and reverse directions by the motor connected to the reel 1 or 2 and the motor connected to the spool 13. Note that the encoder of the roller 10 generates a number of pulse signals proportional to the amount of transport of the film F. Further, 14 is a pressure roller placed opposite to the feed roller 9, 15 is an auxiliary roller placed opposite to the encoder-equipped roller 10, and 16 is a guide plate for guiding the film F being conveyed.

When the conveyance of the film F is stopped, the plate part 11
It consists of a pair of glass plates that can hold the film F from above and below. The light from the light source 17 such as a lamp passes through the condenser mirror 18 and then enters the condenser lens group 19.
The light is focused by and irradiates the image of the film F corresponding to the plate portion 11. And the image is projected by the projection lens 20
The image is enlarged and projected on the screen 21 or the like at the upper front of the reader printer. 22 is a reflecting mirror.

Therefore, the operator drives the motor in forward and reverse rotation as appropriate based on a manual search or an automatic search for the image displayed on the screen 21, so that the desired image of the film F is transferred to the plate section 11. By stopping the image at a corresponding position, the image can be projected onto the screen 21 for viewing, or by switching the optical path 19, the image can be projected onto a photoreceptor (not shown) in the image forming section and copied.

For example, the roll film carrier section is like this.

The roll film feeding device 8 will be explained below with reference to FIG.

The feeding device 8 according to the illustrated embodiment is used for both a 3MM type cartridge A and an ANSI standard type cartridge B.

First, reel drive! The lJ mechanism 23 will be described.

The reel drive mechanism 23 is configured to be driven and connected to the reel 1 or 2 when the cartridge A or B is loaded, and is connected to the reel 1 or 2 in the direction in which the film F is fed out.

An output gear 27 meshes with the input gear 26, and a base end 29 of the drive shaft 2B is fixed to the output gear 27. The tip end 30 of the drive shaft 28 is engaged with the connecting hole 3 or 4 provided in the center of the reel 1 or 2. Note that the reel 1 or 2 is urged toward the drive shaft 28 by a suppressing member (not shown).

In this way, the rotation of the first motor 24 is transmitted to the lever 1 or 2. The reel drive mechanism 23 that has been conventionally used for tightening the film F and transporting the film F between the reel 1 or 2 and the spool 13 can be changed by simply reversing its rotation. , it can be easily used for sending out books.

The reel drive mechanism 23 is configured in this manner.

Next, hover the tip 30 of the drive shaft 2B.

When the cartridge A is loaded, the flange portion 304 is rotated and fitted into the recess 3' (see FIG. 8) provided in the center of the side surface of the reel 1, and the drive bins 305, 3o5 is inserted into and engaged with the connecting hole 3.3 in the four parts 3' of the reel, thereby transmitting the rotation of the drive shaft 28 to the reel 1.

When the ANSI drive shaft 303 is loaded with the cartridge B, the flange portion 30. of the 3MM drive shaft 302 is inserted. is in pressure contact with the central part of the side surface of the reel 2 and prevented from further eruption, and can protrude relatively further toward the reel 2 than the flange part 304, and its tip is inserted into the square hole of the reel 2. The reel 2 is fitted into and engaged with the shaped connecting hole 4, thereby transmitting the rotation of the drive shaft 2B to the reel 2. Note that when the 3MM drive shaft 302 is used, the ANSI drive shaft 303 is positioned so as not to protrude beyond the flange portion 304 thereof.

The distal end portion 30 of the drive shaft 28 is configured in this manner.

Next, the first pressing roller 31. The second suppression roller 32 will be described.

The first pressing means, such as the first pressing roller 31, includes a free roller that can press against the film F and applies a pressing force. The second suppressing means such as the second pressing roller 32 is capable of being pressed against the film F, is located adjacent to the first pressing roller 31 on the upstream side, and is further rotated or driven in the same direction as the rotational direction of the reel 2. It is possible to switch between a state in which the front end portion f' of the reel is peeled off and a state in which the front end portion f' of the reel 2 is released and driven by the reel 2 in a free state.

33 is a mounting arm, and this mounting arm 33 includes a first arm 34 having a longitudinal plate shape along a vertical plane;
A second arm 35 inclined with respect to the arm 34, and a second arm 35 inclined with respect to the arm 34;
The connecting arm 36 connects the distal end of the arm 34 and the proximal end of the second arm 35. 1st arm 3
The proximal end of 4 is pivotally supported by a fulcrum 37 on a stationary part (not shown) such as a frame. The first pressing roller 31 is pivoted on one side of the tip of the second arm 35, and on the other side,
A plate body urged substantially downward (in the direction of pressure contact with the film F) within a predetermined range by a spring is pivotally attached, and a second pressing roller 32 is pivotally attached to this plate body.

A pressure mechanism 38 urges the mounting arm 33 toward one surface of the film. A pin 40 is protruded from the tally solenoid 39, a hook 41 is engaged with the pin 40, and the other end extension 42 of the hook 41 is connected to the 17th section 34 of the mounting arm 33. connected to the center.

43 is a rotation drive groove of the second suppression roller 32. A rotation shaft 46 is attached to the motor @45 of the second motor 44 which is a drive source.
are connected to each other, and a feed roller 9 is attached to this rotating shaft 46. Further, a pulley 48 is pivotally mounted between the base end of the second arm 35 and the brackets 1 to 17 protruding from the connecting arm 36. This feed roller 9 and pulley 4
A belt 49 is passed between the roller 8 and the second pressing roller 32. Therefore, the second motor 44 causes the feed roller 9 to
is rotationally driven, the belt 49 is run, and the second pressing roller 32 is rotationally driven.

As the second pressing means, a belt 49 is used instead of the second pressing roller 32, and the second pressing roller shown in the figure is a belt 49.
9 may be configured to function simply as a guide roller.

Also, this rotary drive groove 43 becomes operable when an ANSI standard type cartridge B is loaded, and the 3MM
When a type of car i-ridge A is loaded, the motor shaft 45 and the rotation shaft 46 are disconnected, for example, and the state is switched to the non-operational state, and in this case, the feed roller 9 and the second The pressure roller 32 is in a freely rotatable state.

First suppression roller 31. The second pressing roller 32 is configured in this manner.

Next, the feeding means such as the feeding roller 50 will be described.

The feeding means becomes operable when a 3MM type cartridge A is loaded, and for example, the feeding means is activated by the feeding roller 5.
0 is used, but a belt or the like may also be used.

This feed roller 50 has its tip guided to the outside by a reel drive mechanism 23, and is disposed so as to be able to come into pressure contact with the league tape f wound around the outer periphery of the reel 1 by a biasing mechanism 51. 52, the reel 1 is rotationally driven in a direction opposite to the feeding rotation direction of the reel 1.

First, the bias @ structure 51 is as follows. That is, the feed roller 50 is pivotally attached to the tip of the louver 53, and the proximal end of the louver 53 is pivotally supported by a fulcrum 54 on an immovable part (not shown) such as a frame. The center portion of the lever 53 is pivotally connected to the upper end of a connecting rod 55 by a pin 56, and the lower end of the connecting rod 55 is attached to a plunger 58 of a solenoid 57. A spring 60 is interposed between the vicinity of the center of the first lever 53 and a pin 59 fixed to an immovable part such as a frame, and biases the second lever 53 clockwise.

Then, when the solenoid 570 is turned on, the first lever 53 moves around the fulcrum 54 against the biasing force of the spring 60.
The feed roller 50 rotates clockwise (substantially downward) from the retracted position shown in the figure, and the feed roller 50 also rotates from the retracted position shown to the operating position through the window W of the cartridge A and presses against the leader tape f on the outer periphery of the reel 1. be done. Further, when the solenoid 57 is turned off, the lever 53 rotates counterclockwise and returns to the retracted position, and the delivery roller 50 also returns from the operating position to the retracted position (3) in the figure.

Next, the feed drive mechanism 52 is as follows. An input gear 61 is fixed to a motor shaft 45 of a second motor 44 serving as a drive source, and an output gear 62 meshes with the input gear 61. The output gear 62 is pivotally attached to the base end of the louver 53, and a belt 63 is passed between the output gear 62 and the feed roller 50. Therefore, the second motor 44 operates the input gear 61 . The belt 63 is run through the output gear 62, and the delivery roller 50 is rotationally driven.

The feeding means such as the feeding roller 50 is configured as described above.

Next, let's look at the cartridge identification method.

A pair of upper and lower detection switches SW constitute this discrimination means.
'1. SW2 is the instrumented cartridge A and B.
As shown by the dashed line and the dashed double dot line in FIG.

The upper detection switch SW1 is the cartridge A.

The lower detection switch SW2 is pushed only by the device of cartridge A. The signal from the detection switch SW1.2 is input to the microcontroller for operation control, and it is determined whether cartridge A or B is loaded by checking that the detection switch SW1 is turned on, and by checking that the detection switch SW2 is turned on. It is determined whether the loaded cartridge A or B is of type. Based on this determination result, the reel drive mechanism 23
3MM drive! 1ill1302 and ANSI drive shaft 30
3, movement and rotational drive of the feed roller 50, second pressing roller 32. The rotational drive of the feed roller 9, etc. are controlled.

Note that, in place of the detection switch SW1.2, it is of course possible to employ various detection means.

The cartridge discrimination means is constructed as described above.

Next, the pressure roller 1/1 will be described.

The pressure roller 14 is attached to the tip of the second lever 64.
11, and this second lever 6/1 has its base end at the fulcrum 6.
5 is pivoted to a fixed part such as a frame, and the center part is connected to a plunger 67 of a solenoid 66 by a rod 68.
They are connected via a pin 69. A pin 70 is fixed near the tip of the second lever 64 and to an immovable part such as a frame.
A spring 71 is interposed between the second lever 64 and the second lever 64.
is biased clockwise. Then, when the solenoid 66 is turned on, the second lever 64 resists the biasing force of the spring 71 and rotates counterclockwise (approximately downward) from the retracted position shown in FIG. : and is pressed against the feed roller 9. Here, if ANS I standard type cartridge B is installed in the device, Bell i-4
, the pressure roller 14 is rotated accordingly, and when the film F is fed out on the belt 49, the pressure roller 14. Belt 49. This is sent to the next conveyance system by the feed roller 9 or the like. On the other hand, when a 3MM type cartridge A is loaded, the bell [4] does not run as described above, so both the pressure roller 14 and the feed roller 9 are in a freely rotatable state.

The pressure roller 14 is configured as described above.

This concludes the explanation of the configuration.

Next, the operation mechanism of this roll film feeding device 8 will be explained.

First, a cartridge A or B containing a long film F wound into a roll on a reel 1 or 2 is loaded into a roll film carrier section of a reader printer or the like.

First, the type of cartridge A or B is determined by the cartridge determining means such as the detection switch SW1.2.

Therefore, a case in which a 3MM type cartridge A is installed will be described with reference to FIG. 5 as well.

Based on No. 49 from the cartridge discrimination means, reel drive P! 1 mechanism 23 3MM drive @302 is advanced,
The flange portion 304 is fitted into the recess 3' of the reel 1, and its drive pins 305, 305 are fitted into and engaged with the connecting holes 3, 3 of the reel 1. At this time, the first motor 24 is turned on, each of the above operations is performed while rotating, and the first motor 24 is once turned off when the operation is completed.

Next, as shown in FIG. 5(1), a high-speed winding and tightening operation is performed. There is a possibility that the inside of the fills 1 and \F may be loose, and this is done in order to eliminate such loose winding. That is, the first motor 24 of the reel drive mechanism 23 is turned on and rotates forward at high speed for several seconds, and the reel 1 is rotated by a predetermined amount in a counterclockwise direction opposite to the feeding direction, so that the reel 1 is wound on the reel 1. The film F is further rotated in the winding direction and wound tightly.

Next, as shown in FIG. 5 (2), a low speed winding and tightening operation is performed. That is, the rotational speed of the first motor 24 is reduced, and the film F is further tightened. Note that this low-speed winding and tightening operation is performed by the first suppressing roller 31. The second pressing roller 32 is pressed against the surface of the film F. That is, at the start of the low-speed seaming operation, the rotary solenoid 39 is turned on, and the mounting arm 33 rotates from the retracted position shown in FIG. 1 to the operating position, so that the first pressing roller 31. The second pressing roller 32 is pressed against the film F surface. Here, as mentioned above, since the pressing force of the first pressing roller 31 against the film surface F is based on the rotational force stirring of the rotary solenoid 39, the pressing force against the film 1 surface based on the urging force of the spring of the second pressing roller 32 is also set strongly. Therefore, mainly due to the pressing force applied by the first pressing roller 31, the mutual frictional force inside the film F is further increased, so that the film F is wound tightly from this side as well, while preventing the occurrence of loosening. Note that since the rotational drive mechanism 43 is not driven, the second pressing roller 32 is in pressure contact with the first surface of the film in a freely rotatable state. Therefore, both the first pressing roller 31 and the second pressing roller 32
By pressing against the surface, it is driven to rotate in the opposite direction, that is, clockwise.

When the winding operation is completed, the first motor 24 is temporarily turned off.

Then, as shown in FIG. 5(3), feeding of the leader tape f of the film F is started.

First, the first seventh motor 24 is turned on again, but its rotation is reversed. Therefore, since the reel 1 is rotated in the cutting direction, the film F is rotated in the feeding direction, that is, the direction in which the outer periphery of the film F is unraveled.

] Pressing roller 31. Since the second pressing roller 32 is rotated counterclockwise, the leader tape f is sandwiched between the outer peripheral edge of the reel 1, the first pressing roller 31, and the second pressing roller 32. , thereby the rotational force is transmitted to the leader tape f.

The leader tape f at the leading end of this film F is
Made of sturdy, hard and thick material, and cartridge A
The feed roller 50 is also not pressed near the upstream area of the area facing the opening 7.

Therefore, the leader tape f leaves the outer periphery of the reel 1 from its tip due to its own rigidity, travels approximately tangentially, and reliably follows a trajectory toward the opening 7 of the cartridge A. In this way, the tip of the leader tape f passes through the opening 7,
led to the outside. Note that during this time, the first suppression roller 31 and the like continue to be in pressure contact with the film F.

Now, the leading end of the leader tape r led to the outside is guided by the temporary guide 16, and the free feed roller 9. When the solenoid 66 is turned on, it travels through the pressure roller 14, which is set to the operating position, and the encoder-equipped roller 10 and the auxiliary roller 15.
When the leader tape f moves, the encoder-equipped roller 10 rotates, thereby generating an encoder pulse. In addition, for detecting the leading end of the leader tape f, it is possible to use various other detection means instead of the encoder-equipped roller 10.

Now, when the leading edge of the leader tape f is detected in this manner, the following three operations are performed based on the detection signal, as shown in FIG. 5 (4). First, the first motor 2
4 is off and reel 1 is free to rotate. Second, the pressure applied to the film F by the first pressure roller 31 and the like is released. That is, the three rotary lean lenses are turned off, and the mounting arm 33 returns from the operating position to the retracted position. Thirdly, instead, the Kiseki Organization 51
The solenoid 57 is turned on, and the feed roller 50 is pressed against the leader tape f on the outer periphery of the reel 1. Also, the second motor 44 of the feed drive mechanism 52 is turned on, and the feed roller 5
Since reel 0 is rotated in the opposite direction to the previous rotational direction of reel 1, reel 1 continues to rotate as before.

In this way, the feeding of the leader tape f and furthermore the main body of the film F is performed by the feeding roller 50 from this point on.

Now, the film F is further fed and conveyed, and when the leader tape f reaches the spool 13, the connected motor (
First, this leader tape is wound up by the spool 13 which is rotated at high speed by a roller (not shown). Then, the traveling speed of the film F increases and the number of encoder pulses from the encoder roller 10 changes, so that winding of the leader tape f onto the spool 13 is detected.

Based on the detection signal, firstly, the solenoid 57 is turned off and the delivery convex roller 50 is returned to the retracted position from the actuating device, and secondly, the second motor 44 is also turned off and the delivery roller 50 is turned off.
rotation also stops, and the solenoid 66 is also turned off. Note that a timer is appropriately used for such control.

The post film F is transported in forward and reverse directions by the rotation of the reel 1 and the spool 13.

In this way, the film F can be fed out reliably and smoothly when the 3MM type cartridge Δ is used.

) The case where an ANSI standard type cartridge B is loaded will be described with reference to FIG. 6 as well.

First, based on the signal from the cartridge discriminating means, the flange part 304 of the reel driver @23 is pressed against the central part of the side surface of the reel 2, and the ANSI drive shaft 303 is protruded from the flange part 304 and inserted into the connection hole of the reel 2. 4 and is engaged.

As shown in Figure 6 (1) and (2),
The film F is tightened. This winding and tightening is performed in the same manner as explained in FIG. 5 (1) and (2) above, so the explanation thereof will be omitted.

When the winding operation is completed, the first motor 2/1 is temporarily turned off in the same way as described above, and then, as shown in FIG. 6 (3), feeding of the front end f' of the film F is started. .

First, the first motor 24 is turned on again, but its rotation is reversed as before. Therefore, since the reel 1 is rotated clockwise, the film F is rotated in the feeding direction, that is, in the direction of unwinding its outer circumference.

At the same time, the second motor 4/1 is turned on, the rotary drive groove 43 is activated, the belt/19 is run, and the feed roller 9. It is pressed against the film F in a free state, and when the second pressing roller 32 and the solenoid 66 are turned on, the pressing roller 14 in the operating position is driven to rotate.

Now, since this second pressing roller 32 is rotationally driven in the clockwise direction, the film F is peeled off from its front end f' by this second pressing roller 32, and is reliably guided to the outside through the opening 7. . Note that the first pressing roller 31 is also pressed against the surface of the film F in the same way as in the previous example (E), and while being rotated counterclockwise, it applies a pressing force to the surface of the film F to prevent it from loosening.

Since the first pressing roller 31 and the second pressing roller 32 are arranged adjacent to each other, the occurrence of loops at the front end portion f' is also reduced.

In this way, the film F is moved from its front end f' to the second
It is guided to the belt 49 by the suppression roller 32, placed on the running belt 49, and further sent and conveyed by the feed roller 9 and the pressure roller 14.

In this case, unlike the case of loading the 3MM cartridge A described above, even if the encoder-equipped roller 10 detects that the front end f' of the film F has arrived, no new operation is performed and the previous operation is continued. Ru.

Now, the film F is further fed and conveyed, and the front end f'
When it is wound onto the spool 13, the winding is detected in the same manner as described above. Based on the detection signal, the rotary solenoid 39 is first turned off and the first suppression roller 31 is turned off, as shown in FIG. The second suppression roller 32 releases the pressure contact with the film F and returns from the operating position to the retracted position. Furthermore, secondly, the second motor 44 is turned off and the second pressure roller 32 . Feed roller9. The rotational drive of the pressure roller 145 is also stopped, and the third solenoid 66
Also turns off.

The post film F is transported in forward and reverse directions by the rotation of the reel 1 and the spool 13.

During this time, the feed roller 50 is in the retracted position and is not operated at all.

In this way, the film F can be fed out reliably and smoothly when the ANSI standard type cartridge B is loaded.

Further, the roll film feeding device 8 according to this embodiment has the advantage that it can be used in common with the 3MM type cartridge A and the ANSI standard type cartridge B.

In other words, in the past, it was common practice to use dedicated machines for each, or to replace parts and use them for each, but according to this embodiment, the cartridges are automatically switched and can be used for both types of cartridges. Compatible with A and B loading,
There is no need for troublesome parts replacement work.

"Effect of the invention" Roll film feeding according to the present invention)? As explained above, when feeding the leading edge of the film of a 3MM type cartridge, the reel drive mechanism first guides the leading edge of the league tape to the outside, and then the feeding means is driven into pressure contact with the leader tape. , the film can be easily and reliably and smoothly fed out from within the cartridge. In other words, when the leading edge of the film comes into contact with a guide etc. during feeding, jams caused by getting caught or jammed are prevented, and the situation where the leading edge of the film is not fed out and rotates inside the cartridge is also eliminated. It is realized with a simple structure, and the problems that existed in conventional delivery devices of this type are completely eliminated, and the effects it brings are remarkable and great.
