Description

  The present invention relates to a paper magazine for storing recording paper, and more particularly to a paper magazine for conveying recording paper and sending it to an image recording apparatus such as a printer.

  In a printer that prints an image from a negative film onto a photosensitive material such as photographic paper, a paper magazine containing a photosensitive material wound in a roll shape in a paper tube is loaded in advance, and the photosensitive material is drawn out from the paper magazine. Then, the sheet is cut into a desired size by a cutter, the cut photosensitive material is conveyed to a printer, and an image is printed on the photosensitive material. The photosensitive material on which the image is printed is sent to a developing device subsequent to the printer for development processing.

  Such a paper magazine is provided with a conveying device for drawing out the photosensitive material. As a conveying device, a driving roller and a nip roller that sandwiches the photosensitive material together with the driving roller at a position facing the driving roller are provided in the paper magazine, and the driving roller is rotated by a driving source provided in a processing device body such as a printer. In addition, a photosensitive material is conveyed by holding the photosensitive material between a driving roller and a nip roller (Patent Document 1).

  On the other hand, in order to increase the conveyance stability of the photosensitive material, it is sufficient to increase the nip pressure of the photosensitive material by the nip roller. However, if this nip pressure is too high, the photosensitive material may be fogged or have a nip mark. There is a fear. For this reason, there is also a transport device that is provided with a pair of nip rollers and applies the desired nip pressure to the photosensitive material as a whole even if the nip pressure of each nip roller is reduced, thereby improving the transport stability of the photosensitive material. Are known. Note that the transport apparatus described in Patent Document 1 also uses a pair of nip rollers to improve the transport stability of the photosensitive material.

  Further, in an image recording apparatus such as a printer, when the size of a photosensitive material to be used is different, it is necessary to replace it with a paper magazine loaded with the photosensitive material of the different size. At this time, if the photosensitive material is pulled out from the paper magazine, the front end of the photosensitive material is exposed. For this reason, when processing such as development of the photosensitive material is completed, the driving roller is rotated in the reverse direction, the photosensitive material is rewound, and the leading end thereof is accommodated in the paper magazine. The exposure of the material tip is prevented.

JP-A-7-114108

  The drive roller and nip roller are always in pressure contact with the photosensitive material in a linear contact in the width direction. Therefore, if the drive roller and the nip roller are not used for a long period of time, a linear mark due to the nip will be left on the tip of the photosensitive material. In addition, since the surfaces of both rollers are made of a flexible rubber material or the like, the surfaces of both or one of the rollers may be deformed. Also, the drive roller and nip roller, when using a paper magazine for a long time, changes in the shape due to the adhering material such as paper dust generated from the photosensitive material, the plastic deformation described above, or the deterioration of the material properties of the roller surface. This may reduce the frictional resistance of a part of the surface. In this case, the conveying force of the driving roller varies, and there is an inconvenience such as an error in the feed length of the photosensitive material and a shift in the position where the photosensitive material is cut. Further, the drive roller and the nip roller are configured to always nip both ends in the width direction of photosensitive materials having different sizes. For this reason, a large amount of paper dust is generated from both ends of the photosensitive material, which promotes the above-mentioned disadvantages.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a paper magazine that can prevent the deformation of the surface of the drive roller and can accurately manage the feeding length of the photosensitive material in the long term. . Another object of the present invention is to prevent a decrease in frictional resistance on the surface of the driving roller without generating paper dust.

  The paper magazine of the present invention comprises: a belt wound between a plurality of belt wheels provided at predetermined intervals; and a driving roller that rotates by a driving force transmitted from the outside of the paper magazine; The recording paper is sent out by press-contacting the recording paper on the outer peripheral surface of the belt wound between the plurality of belt wheels. The belt is configured to follow the rotation of the drive roller. As the belt, any belt such as a rubber belt or a leather belt can be used as long as it is made of an elastic material. As the belt wheel, a flat belt is desirable when a roller or roller shape is used. In addition, you may use not only a flat belt but a toothed belt, a V belt, etc. FIG. In this case, a belt wheel having teeth or V-shaped grooves may be used.

  A plurality of belts and driving rollers may be provided side by side in the width direction of the recording paper. In this case, the belts on both sides are arranged so that the nipping range between the belts arranged on both sides in the width direction and the driving rollers in pressure contact with the belts is an interval that does not reach both ends (edges) in the width direction of the recording paper. It is desirable to do so because it is difficult for paper dust to be generated.

  The tension applied to the belt is determined by the distance between the belt wheels, the diameter of the belt wheel, and the belt circumference. However, when used for a long time, the tension of the belt gradually decreases due to the stress relaxation of the belt due to environmental changes. For this reason, it is preferable to provide a tension applying mechanism that applies tension of the belt to at least one of the plurality of belt wheels.

  In the paper magazine of the present invention, the driving roller is pressed against the outer circumference of the belt between the plurality of belt wheels, so that the belt is in close contact with the outer circumference of the driving roller so as to surround the arc, and the driving roller faces the recording paper. Pressure contact. For this reason, there is no variation in the pressure contact force to the drive roller, and the pressure contact is made uniformly, so that the recording paper feed accuracy is improved. In addition, since the driving roller and the belt are in surface contact, even if the leading end of the recording paper is nipped for a long time, it is difficult for the recording paper to have a pressure contact mark. Furthermore, since an endless circulation belt is used, the guide plate on the belt side can be omitted. Further, in the invention in which the belt and the drive roller are configured not to nip both ends (edges) of the recording paper, the generation of paper dust can be reduced, so that a reduction in conveying force (decrease in frictional resistance) is prevented. be able to.

  As shown in FIGS. 1 and 2, the paper magazine 10 includes a box-shaped magazine main body 13 in which a roll core 11 on which a roll-shaped photosensitive material (recording paper: not shown) is supported can be loaded from an opening portion 12. A lid 15 is attached to one end of the magazine body 13 via a hinge 14. And the cover part 15 rotates centering on the hinge 14, The opening part 12 can be sealed.

  The magazine body 13 and the lid portion 15 are formed with bearing portions 16 that hold both ends of the core 11. The bearing portion 16 has an octagonal shape so as to be fitted to the holding portions 17 provided at both ends of the winding core 11, so that when the winding core 11 is loaded into the paper magazine 10, the holding portion 17 rotates. The bearing 16 is held in an impossible state.

  The winding core 11 includes a center core 20 and a pair of flange portions 21 and 22, and the width of the conveyance path (recording paper passage) of the paper magazine 10 is centered in the width direction of the roll-shaped photosensitive material by the flange portions 21 and 22. The photosensitive material is held in a roll shape by being regulated so as to match the center of the direction. The holding portion 17 is attached to both ends of the core 20 so as to be rotatable with respect to the core 20. A friction member 23 such as a felt is attached between the holding portion 17 and the core 20. Accordingly, a certain amount of frictional force is generated when the core 20 is rotated with respect to the holding portion 17, and therefore, when the core 11 is loaded in the paper magazine 10, the core 11 is not subjected to a certain amount of rotational force. As a result, the winding core 11 is prevented from rotating unnecessarily. The photosensitive material is wound around the outer periphery of the core 20 between the flange portions 21 and 22.

  The magazine body 13 is provided with a drive roller unit 25, a detection lever 26, a pair of guide portions (paper guides) 27 and 28, and a roller roller 29. The pair of guide portions 27 and 28 is provided so as to be movable in the width direction of the photosensitive material, and is attached at a position suitable for the width of the photosensitive material to be used so that the guide interval is adapted to the width of the photosensitive material. is there. The lid portion 15 is provided with a driven belt unit 30.

  FIG. 3 shows a state in which the paper magazine 10 is set in the loading chamber 33 of the image recording apparatus 32 with the magazine body 13 facing up and the lid portion 15 facing down. The photosensitive material 31 is guided by the roller 29 through the flange portions 21 and 22, and further guided in the width direction by the guide portions 27 and 28, and further between the driving roller unit 25 and the driven belt unit 30. Then, the photosensitive material 31 is fed from the front end to the inside of the image recording device 32 through the opening 34 formed at the joint of the magazine body 13 and the lid 15.

  The magazine body 13 is provided with a shutter mechanism (not shown) for blocking light from entering the paper magazine 10 from the opening 34. The shutter mechanism includes a set completion detection pin and a shutter body that opens the recording paper path in the opening 34 by the displacement of the set completion detection pin. The shutter body is normally set at a closed position by spring biasing, and blocks light from entering the paper magazine 10 from the opening 34. When the paper magazine 10 is set in the loading chamber 33 and the opening 34 faces the recording paper path in the image recording apparatus, the setting completion detection pin is pushed and displaced, and this displacement causes the shutter body to move from the closed position. By moving to the opening position, the recording paper can be taken in and out from the opening 34. The set completion detection pin is provided so as to protrude in the recess so as not to be pushed and displaced in normal handling. In addition, the shutter main body is set to the open position in a state where light does not enter the paper magazine 10 even if the paper magazine 10 is securely set in the loading chamber 33 and the shutter main body is opened. Note that the shutter mechanism may be one that opens and closes the shutter body using a solenoid or a motor instead of the one interlocked with the set completion detection pin.

  The drive roller unit 25 is provided with a pair of drive rollers 35 and 36 and a joint portion 37 (see FIG. 1) at the end of a shaft 40 that fixes the rollers. When the paper magazine 10 is set in the loading chamber 33, it is jointed to a drive mechanism 38 provided in the image recording device 32. The drive mechanism 38 includes a pulse motor 39, a driver 42, and a control unit 43 that controls the pulse motor 39. The control unit 43 controls forward / reverse rotation of the drive rollers 35 and 36 and stop of the drive.

  The detection lever 26 rotates between a position where the detection lever 26 can project into the conveyance path of the photosensitive material 31 and a position where it can be retracted from the conveyance path. The detection lever 26 is moved to the retractable position during conveyance of the photosensitive material 31, but protrudes into the conveyance path when the photosensitive material 31 is exhausted. Therefore, if it is detected that the detection lever 26 protrudes into the conveyance path, it is possible to detect the out of sheet of the photosensitive material 31. The position of the detection lever 26 is detected by a sensor provided in the image recording device 32. A signal output from the sensor is input to the control unit 43 of the drive mechanism 38, and thereby the rotation of the pulse motor 39 and thus the drive rollers 35 and 36 is controlled.

  As shown in FIG. 4, the drive roller unit 25 is formed by fixing a plurality of rubber rollers to the shaft 40 with a predetermined interval therebetween, and the plurality of rubber rollers are arranged on the left and right sides with respect to the center in the width direction of the conveyance path. . A pair of rollers disposed near the center of the plurality of rubber rollers are drive rollers 35 and 36, and the other is a sub drive roller 41. A joint portion 37 is fixed to one end of the shaft 40. The detection lever 26 is disposed between the pair of drive rollers 35 and 36. Guide portions 27 and 28 are disposed upstream of the drive rollers 35 and 36 in the pulling direction, and roller rollers 29 are disposed upstream of the guide portions 27 and 28.

  The driven belt unit 30 includes a first belt wheel unit 44, a second belt wheel unit 46, a pair of flat belts 47 and 48, and a pair of coil springs 60 and 61 (tension applying mechanism). The first belt wheel unit 44 has a configuration in which a pair of first belt wheels 49 and 50 and a plurality of driven rollers 51 are provided on a shaft 52. The first belt wheels 49 and 50 are crown-shaped rollers whose peripheral surfaces swell in a barrel shape in order to prevent the flat belt from being biased, and the center of the conveyance path in the width direction so as to correspond to the drive rollers 35 and 36. Are arranged symmetrically. The first belt wheels 49 and 50 are provided with a bearing between the shaft 52 and are rotatable with respect to the shaft 52. The plurality of driven rollers 51 are provided in the same number as the sub drive rollers 41 and spaced apart from each other, and are rotatable with respect to the shaft 52. Even when set to 1, the both ends (edges) in the width direction of the photosensitive material serve as guide rollers so as not to be caught inside the paper magazine. The shaft 52 is supported by the lid portion 15. That is, the sub drive roller 41 and the driven roller 51 are not in pressure contact with each other and are separated from each other. The sub drive roller 41 and the driven roller 51 constitute a guide roller of the present invention.

  The second belt wheel unit 46 is arranged on the upstream side in the pulling direction with respect to the first belt wheels 49 and 50, and is composed of a pair of second belt wheels 53 and 54 and a shaft 55 that supports them. ing. The pair of second belt wheels 53 and 54 are also crown-shaped rollers whose peripheral surfaces swell in a barrel shape to prevent the flat belt from being biased, and are arranged symmetrically with respect to the center in the width direction of the transport path. ing. The second belt wheels 53 and 54 are provided with a bearing between the shaft 55 and are rotatable with respect to the shaft 55. Further, the shaft 55 is rotatably held with respect to the lid portion 15.

  The flat belt 47 is wound around the first and second belt wheels 49 and 53, and the other flat belt 48 is wound around the first and second belt wheels 50 and 54, respectively. As shown in FIG. 5, the drive rollers 35 and 36 are in pressure contact with the outer circumference between the first belt wheels 49 and 50 and the second belt wheels 53 and 54 of the flat belts 47 and 48. Specifically, they are pressed against the outer peripheries of the flat belts 47 and 48 excluding the range wound around the first and second belt wheels 49, 50, 53 and 54, respectively. The shaft 55 that supports the second belt wheels 53 and 54 is biased by the coil springs 60 and 61 in a direction away from the first belt wheels 49 and 50. The urging directions of the coil springs 60 and 61 are opposite to the pulling direction (winding direction).

  As a result, a predetermined tension is applied to the pair of flat belts 47 and 48, and when the lid portion 15 is closed with respect to the magazine body 13, the driving rollers 35 and 36 press the flat belts 47 and 48 against each other. Thus, the flat belts 47 and 48 are bent. With such a configuration, even if the pressure contact of the lid portion 15 with respect to the magazine body 13 changes, the tension applied to the flat belts 47 and 48 is automatically adjusted by the expansion and contraction of the coil springs 60 and 61. Therefore, the pressure contact between the flat belts 47 and 48 and the drive rollers 35 and 36 is always constant.

  The photosensitive material 31 has different types. The two flat belts 47 and 48 and the driving rollers 35 and 36 arranged in the width direction of the photosensitive material 31 are within a range where both ends (edges) of the photosensitive material with the shortest width are pressed to reduce the generation of paper dust. It is placed at a position where it does not take.

  Next, the operation of the above configuration will be described. First, an operation for setting the photosensitive material 31 in the paper magazine 10 is performed. At this time, the lid portion 15 is opened with the magazine body 13 in a downward position, and the core 11 is removed. The flange portions 21 and 22 are removed from the winding core 11, the photosensitive material 31 is set on the center core, and the flange portions 21 and 22 are attached to both sides again. The core 11 on which the photosensitive material 31 is set is stored in the magazine body 13. At this time, the front end of the photosensitive material 31 is drawn out to the length exceeding the driving rollers 35 and 36 via the roller 29. Thereafter, when the lid 15 is closed, the leading end of the photosensitive material 31 is nipped between the driving rollers 35 and 36 and the flat belts 47 and 48.

  The completed paper magazine 10 is set in the loading chamber 33 of the image recording device 32. With this set, a drive system connection and an electrical connection are made between the paper magazine 10 and the image recording device 32, and the drive from the drive mechanism 38 of the image recording device 32 can be transmitted to the joint portion 37. The position of the lever 26 can be detected by the sensor of the image recording device 32.

  When the paper magazine 10 is set in the loading chamber 33, a preparatory operation for cutting the leading end of the photosensitive material 31 that has been drawn out is automatically performed. In this operation, the driving mechanism 38 of the image recording apparatus 32 rotates the driving rollers 35 and 36 in the feeding direction so that the front end of the photosensitive material 31 niped with the flat belts 47 and 48 faces the opening 34. Send it out. At this time, the driving rollers 35 and 36 are pressed so as to bend the flat belts 47 and 48, and the flat belts 47 and 48 are wound around a part of the outer periphery of the driving rollers 35 and 36 in an arc shape. It has become. For this reason, the drive rollers 35 and 36 can send out the photosensitive material 31 in surface contact with the flat belts 47 and 48. This is because the pressure contact force is averaged even if there is a factor that reduces the frictional resistance on a part of the outer periphery of the drive rollers 35 and 36, so that the photosensitive material 31 can be fed out with high accuracy. Moreover, the tensions of the flat belts 47 and 48 vary because the shafts 55 of the second belt wheels 53 and 54 are moved by the expansion and contraction of the coil springs 60 and 61 to change the distance between the shafts of the first belt wheels 49 and 50. Prevented and kept constant.

  As shown in FIG. 3, the image recording apparatus 32 is provided with a cutter mechanism 70 on a conveyance path through which the photosensitive material 31 is conveyed. Driving during the preparatory operation of the drive mechanism 38 is a rotation amount (time) that stops when the leading edge of the photosensitive material 31 passes through the cutter mechanism 70. Thereafter, the cutter mechanism 70 is operated to cut off the excessive tip of the photosensitive material 31. After the cutting, the driving mechanism 38 inputs reverse driving, rotates the driving rollers 35 and 36 in the winding direction, and rewinds the photosensitive material 31. As a result, the front end of the photosensitive material 31 is reversely conveyed from the cutting position of the cutter mechanism 70 toward an arbitrary return position in the pressure contact range between the driving rollers 35 and 36 and the flat belts 47 and 48.

  When the front end of the photosensitive material 31 reaches the return position, the detection lever 26 protrudes into the conveyance path because it passes through the detection lever 26. Thereby, the drive mechanism 38 recognizes that the front end of the photosensitive material 31 has reached the return position, and stops the reverse rotation drive. Thereby, the preparation of the image recording apparatus 32 is completed. At the time of rewinding, since the transport path length between the cutter mechanism 70 and the return position is short, the photosensitive material 31 is not rewound by rotating the winding core 11 in the winding direction. 10 is slackened inside.

  When a print instruction is input to the image recording device 32, as described above, the drive of the drive mechanism 38 is transmitted to the drive rollers 35 and 36, and the drive rollers 35 and 36 send out the photosensitive material 31. After a desired amount of the photosensitive material 31 is conveyed from the cutter mechanism 70, the drive mechanism 38 temporarily stops driving, and the cutter mechanism 70 is operated to cut the photosensitive material 31 into a sheet shape corresponding to the size. At this time, the leading end of the photosensitive material 31 is nipped by a conveying roller pair 71 provided inside the image recording apparatus 32. The cut photosensitive material sheet 31a is conveyed to a recording unit and a developing unit in the subsequent stage by a conveying roller pair 71, and an image is recorded and developed. Then, by repeating the above operation, a desired number of photosensitive materials 31 are conveyed to the exposure unit by the conveying roller pair 71.

  At this time, when the photosensitive material 31 runs out, the detection lever 26 protrudes into the transport path as shown by the dotted line in FIG. 3, so that the drive mechanism 38 stops driving and displays an indication that the paper is out. Do. The operator can load the photosensitive material 31 into the paper magazine 10 by looking at this display.

  When the feeding of the predetermined number of photosensitive materials 31 is completed, the driving mechanism 38 inputs reverse driving to the driving rollers 35 and 36. As a result, the drive rollers 35 and 36 are reversely rotated so as to wind the photosensitive material 31 into the paper magazine 10. As a result, the front end of the photosensitive material 31 is reversely conveyed from the cutting position of the cutter mechanism 70 to the return position, and the drive mechanism 38 stops reverse rotation driving in response to the detection lever 26 protruding into the conveyance path. As a result, the tip of the photosensitive material 31 is nipped within the pressure contact range between the drive rollers 35 and 36 and the flat belts 47 and 48.

  In this state, the front end of the photosensitive material 31 is not exposed because the front end of the photosensitive material 31 is completely accommodated in the paper magazine 10. Further, since the leading end of the photosensitive material 31 is pressed in a plane shape instead of a linear shape between the driving rollers 35 and 36 and the flat belts 47 and 48, a linear nip mark is attached to the leading end of the photosensitive material 31. There is nothing.

  In the above-described embodiment, the conveyance device that conveys the photosensitive material 31 has been described. However, the present invention is not limited to this, and a recording sheet for recording an image such as plain paper or thermal paper may be used.

  In each of the above embodiments, two sets of the drive rollers 35 and 36 and the flat belts 47 and 48 are provided side by side in the width direction of the photosensitive material 31, but may be one or three or more.

  In each of the above-described embodiments, the paper magazine 10 is set in the loading chamber 33 in a posture in which the flat belts 47 and 48 are positioned under the driving rollers 35 and 36. You may make it set with the attitude | position facing upward.

  In each of the above embodiments, the photosensitive material 31 that has been rewound is slackened inside the paper magazine 10. However, the photosensitive material 31 may be wound around the core 20 by rotating the winding core 11 only during rewinding. Good.

  In each of the above embodiments, the belt wheels 49, 50, 53, 54 are attached to the shafts 45, 40 via bearings. However, since the flat belts 47 and 48 also receive a pressing force, a radial load is applied to the shafts 45 and 40 and the bearings of the bearings, and slip occurs between the inner ring of the bearing and the shafts 45 and 40, so that the shafts 45 and 40 are moved. There is a risk of inconvenience of wearing. Therefore, it is desirable to provide a bearing made of resin between the shafts 45 and 40 and the bearing so that the bearing and the shafts 45 and 40 do not directly contact each other.

  Further, in each of the above embodiments, the flat belt 47 is wound around the two belt wheels 49 and 53, and the flat belt 48 is wound around the two belt wheels 50 and 54, respectively. The number of belt wheels around which the belt is wound may be three or more. Further, the tension applying mechanism is not limited to the coil springs 60 and 61, and known urging means such as an elastic member can be used. In addition, two coil springs 60 and 61 are provided for applying tension to the belts 47 and 48, but the present invention is not limited to this, and only one is provided so as to apply belt tension to at least one belt wheel. But you can.

  In the above embodiment, the joint portion 37 is provided at one end of the shaft 40 of the drive roller unit 25, and a driving force is applied from the outside of the paper magazine 10 through the joint portion 37. In this case, a motor may be built in, so that the driving rollers 35 and 36 may be rotated. Furthermore, although the belt wheels 49, 50, 53, 54 and the belts 47, 48 are attached to the lid portion 15 and the drive rollers 35, 36 are attached to the magazine body 13, they may be attached in reverse.
