Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sheet conveyance device used for conveying a sheet of photosensitive film or the like in, for example, a medical image recording device or an image reading device. .

[Prior Art] Fig. 5 shows a conventional example of a sheet conveying device in a recording bag device that optically records an image on a recording sheet, and is disclosed in Japanese Patent Application Laid-Open No. 1983-1989.
This method is proposed in Japanese Patent No.-118550. S denotes stacked unused photosensitive recording sheets, which are stored in the supply magazine 1. A suction cup 3 connected to an air cylinder 2 is provided above the tip of the seat S, and these air cylinder 2 and suction cup 3 are vertically rotatable about a shaft 4, and when descending, the air cylinder 2 The sheet S is sucked by the air suction operation of , and the leading edge of the uppermost sheet S is lifted. The conveyor roller pair 5 has a mechanism that can move in the horizontal direction, and starts rotating in response to a sheet conveyance start signal, moves to the right, and picks up the lifted sheet S.
The sheet S is conveyed onto the holding plate 6 and then stopped.

The bushing lever 7 and the stopper 8 are rotatable about shafts 9 and 10, respectively, and have a mechanism that can move forward and backward with respect to the sheet conveyance path. The sheet S is conveyed by the conveyor roller pair 5.
While being transferred from the supply magazine l to the holding plate 6, the bushing lever 7 is retracted upward from the conveyance path, and the stopper 8 is lowered into the conveyance path. When the sheet S is fed onto the holding plate 6, the bushing lever 7 rotates clockwise and pushes the rear end of the sheet S forward.

At this time, the leading end of the sheet S comes into contact with the stopper 8, and the center portion of the sheet S is bent upward by the biasing force of the bush lever 7. Subsequently, the bushing lever 7 rotates counterclockwise to release the biasing force against the rear end of the seat S. As a result, the sheet S is placed flat on the holding plate 6, and its tip is corrected for inclination by the stopper 8.

Next, the stopper 8 rotates clockwise to retreat from the conveyance path, and the bushing lever 7 rotates clockwise to push the rear end of the sheet S.

As a result, the sheet S slides on the holding plate 6, and the leading end of the sheet 1-S is sandwiched between the rotating sub-scanning drum 11 and the nip roller 12. The sub-scanning drum 11 is continuously rotated counterclockwise during the recording operation, and the nip roller 12
It is always in contact with this sub-scanning drum II and rotates as a result. When the sheet S is sandwiched between the sub-scanning drum 11 and the nip roller 12 at the previous stage, the sheet S is immediately conveyed to the left by the rotational force of the sub-scanning drum 11.

On the other hand, the optical system unit 13 is installed above the holding plate 6, and the laser beam 2 emitted from the laser light source 14 is irradiated between the two nip rollers 12 via the mirror 15. Main scanning is performed on the sheet S being transported above to form a predetermined image. The sheet S on which the image has been formed in this manner is sent out to the left from between the sub-scanning drum 11 and the nip roller 12 at the rear stage, and is sequentially sagged from its leading edge by its own weight, and is stored in the receive magazine 16.

FIG. 6 shows another conventional example proposed in Japanese Patent Application Laid-Open No. 59-64960, in which S is a sheet made of unused photosensitive film, and sheet S is a supply magazine placed upright on the top. The emulsion sheets are stacked and housed in the container 20 with the emulsion photosensitive surface facing toward the bottom. A suction cup 22 connected to an air pump 21 is provided on the side of the tip of the sheet S. This suction cup 22 can move forward and backward with respect to the supply magazine 20, and when it enters, it sucks the uppermost sheet S in the supply magazine 20 by the suction operation of the air pump 21. When the suction cup 22 sucks the sheet S, it leaves the supply magazine 20 and moves to a guide port formed by guide plates 23a and 23b. Then, the suction operation of the air pump 21 is stopped, and the sheet S falls by its own weight between the pair of supply rollers 24a and 24b using the guide plates 23a and 23b as guides.

The pair of supply rollers 24a and 24b sandwich the sheet S,
The sheet S is transferred downward by the rotational drive, and reaches the stopper 28 through the space between the sub-scanning drum 25 and the nip roller pair 26a, 26b, and the guide plates 27a, 27b. The nip roller pair 26a, 26b can be adjacent to the sub-scanning drum 25, and when the sheet S is fed by the roller pair 24a, 24b, they are retracted from the conveyance path as shown by dotted lines. Further, the stopper 28 can move forward and backward with respect to the feeding path, and is arranged in advance in accordance with the size of the sheet s to be fed. When the sheet S reaches the stopper 28, the sheet S has come off the roller pair 24a, 24b, and the upper end of the sheet S is located between the sub-scanning drum 25 and the nip rollers 26a, 26b, and the sheet S
is in an unrestricted state. In this state, the seventh
The width adjustment devices 29a and 29b shown in the figure operate from both sides of the sheet S, and the sheet S is positioned.

Next, the nip roller pair 26a, 26b moves the sub-scanning drum 2
5 to sandwich the sheet s, and the rotation of the sub-scanning drum 25 transports the sheet S from the bottom to the top, that is, in the direction of the guide plates 30a and 30b. During this conveyance process, the optical system 31 irradiates the nip roller pair 26a.
, 26b. During recording, the sub-scanning drum 25 rotates at a constant speed, and the nip roller pair 26a, 26b also rotates at a constant speed.
Press 5 to follow and rotate. In addition, in order to obtain a high-precision image, high-precision constant-speed feeding is required, and the pair of rollers 32a and 32b in front of the sheet S in the feeding direction are marked with dotted lines so that they do not come into contact with the sheet S during recording. As shown, it has been evacuated from the sheet conveyance path.

In this way, the sheet S on which the image is formed is discharged, and the sheet S can be discharged in two directions. In the first discharge direction, after recording is completed, the pair of rollers 32a and 32b come into pressure contact to sandwich the sheet S, drive it to rotate, convey it to the guide plate 33, and then feed it into the insertion opening of an automatic developing device, etc. This is the case. The second discharge direction is the stopper 2
8 is retracted, and the paper is discharged by the conveyance rollers 34a, 34b, etc. provided below the stopper 28. In this case, when the stopper 28 is retracted after recording is completed and the nip rollers 26a and 26b release the sheet S, the sheet S falls under its own weight and passes between the guide plates 27a and 27b, and then the conveyance roller 34a,
34b and is conveyed to the receiver magazine and discharged to a receive magazine or the like.

[Problems to be Solved by the Invention] Generally, in a recording device that requires high-precision images such as medical images, it is permissible for the scanning line during recording to be tilted significantly diagonally with respect to the outer shape of the recording sheet. Not done. However, when storing unused sheets in the supply magazine,
There is a good chance that the sheet is located at an angle inside the magazine. Therefore, if the sheet is conveyed to the recording section as it is, recording will be performed obliquely to the outer shape of the sheet. Furthermore, the sheet may be tilted diagonally during transportation due to conveyance means such as rollers. Therefore, a means for correcting the inclination of the sheet is essential, and the above-mentioned conventional example also includes a correcting means.

However, the conventional position correcting means described above has the following drawbacks. In the conventional example shown in Fig. 5,
The length of the sheet S used in the conveyance direction is limited to one type, and if sheets S of a plurality of lengths are used, a plurality of bush levers 7 are required, which complicates the mechanism. In addition, when the sheet S is straightened by the biasing force of the bushing lever 7, the sheet S is bent upward, and then when the biasing force is released, the sheet S is moved due to the restoring force that causes the sheet S to return to a flat state. Possibly corrected sheet S
There is a risk that it will tilt again.

Further, in the conventional example shown in FIG. 6, when the sheet S reaches the stopper 28, the sheet S is in an unrestrained state. However, in the gaps between the nip rollers 26a, 26b and the sub-scanning drum 25 and the guide plates 27a, 27b, the sheet S can take any position. Here, since the sheet S is located in a substantially vertical direction, the sheet S buckles due to its own weight. Next, the width adjustment devices 29a, 2
Even if 9b operates, it is difficult to correct buckling from the width direction. Therefore, even if the end face on the stopper 28 side is aligned, the other end side is inclined. This tendency becomes more noticeable with long sheets.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet conveying device that eliminates the above-mentioned drawbacks and corrects the inclination of the sheet by aligning the edges of the sheet.

[Means for Solving the Problems J] In order to achieve the above-mentioned object, a sheet conveying device according to the present invention includes a sheet conveying device that takes out sheets from a storage section in which sheets are stacked and conveys them to a recording position or a reading position. , a holding means for holding the sheet taken out from the storage section in equilibrium, and a correction means that is movable forward and backward relative to the sheet while being held by the holding means and presses an edge of the sheet to correct the inclination of the sheet. , and a feeding means for feeding the sheet to a recording position or a reading position after the sheet is corrected for its inclination by the correction means.

[Operation] In the sheet conveying device having the above configuration, the holding means holds the sheet in balance with the sheet's own weight, and in this state, the sheet straightening means presses the edge of the sheet to correct the inclination of the sheet. to correct.

[Example] Hereinafter, the present invention will be described in detail based on the example illustrated in FIGS. 1 to 4, in which the present invention is applied to an image recording apparatus that records an image by scanning a photosensitive sheet with a light beam. .

FIG. 1 is a configuration diagram of an embodiment of the present invention. A laser optical unit 50 disposed above includes a laser light source, a light modulator, a polygon mirror, etc., and a laser beam modulated according to an image signal. The beam β is deflected in the main scanning direction using rotation of a polygon mirror, and the sheet S at the recording position is
Light scans the photosensitive surface of the Note that while the sheet S is being fed, the recording position is not irradiated with the laser beam 2 by a shutter (not shown) or the like. Laser optical unit 5
The sub-scanning roller pair 51 arranged below 0 is a pair of rollers, one of which has a rotational driving force and the other is driven by it,
The sheet S held between two rollers is conveyed at a constant speed to perform sub-scanning for image recording. Note that the laser beam β from the laser optical unit 50 is main-scanned in the vicinity of the sub-scanning roller pair 2. Below the pair of sub-scanning rollers 51, a supply magazine 52 that stores unrecorded sheets S stacked from below and a receive magazine 53 that stores recorded sheets S are arranged vertically in parallel. The upper surfaces of the magazines 52 and 53 each have sheets S
Slide lids 52a, 5 that can be opened and closed for putting in and taking out
3a, and when the slide lids 52a and 53a are closed, the inside of the magazine 52, 53 is shielded from light from the outside. Note that the film emulsion surfaces of the sheets S laminated inside the magazines 52 and 53 both face downward, further enhancing the light-shielding effect.

Further, in the opening of the supply magazine 52, a suction cup 54 that sucks the uppermost sheet S of the supply magazine 52 by a suction operation is located at a position E with respect to the supply magazine 52.
It is provided so that it can freely move forward and backward between F. In order to convey the taken out sheet S, three pairs of conveying rollers 55, 56, 57 are provided in the exit direction of the supply magazine 52.
Each of these rollers includes drive rollers 55a, 56a, and 57a, and driven rollers 55b, 56b, and 57b that do not have rotational driving force. These three drive rollers 55a, 56a,
57a is driven by one motor (not shown) via a chain, and drive rollers 55a, 56a, 57a
The number of teeth on each sprocket is determined so that all peripheral speeds are the same. Note that the first driven roller 55
b is movable between positions G and H, and in position H is urged and abuts against the first drive roller 55a. The second driven roller 56b similarly reciprocates between positions J, and at position J it contacts the second driving roller 56a and rotates as a result. Further, the third driven roller 57b is located at positions P, Q, R,
It can move between positions P, Q, and R in a planetary manner while contacting the third drive roller 57a, and at position S it retreats from the third drive roller 57a. Furthermore, a first conveyance roller pair 55 and a second conveyance roller pair 56
A pair of nipping rollers 58 consisting of two rollers without driving force is provided on the conveyance path between the two. This pinching roller pair 58 pinches the sheet S, and resists the force of the sheet S trying to come off from the pinching roller pair 58 due to its own weight, and holds the sheet S by a weak frictional force to prevent it from falling. ing.

In order to correct and align the inclination of the sheet S sandwiched between the pair of pinching rollers 58, a resist plate 59 is provided below the second pair of transport rollers 56, and this resist plate 59 rotates around a rotating shaft 59a. , as shown by the dotted line in FIG. 1 and the solid line in FIG. The resist surface 59b is pressed against the end of the sheets S to perform a so-called resist operation in which the sheets S are aligned. Moreover, the back surface of this resist plate 59 has a smoothly processed guide surface 59c.
When the resist plate 59 is in the position shown in FIG. 2, the sheet S can slide on this guide surface 59c with almost no friction.

In addition to the above, a sheet guide plate 60 is provided on the conveyance path between the second conveyance roller pair 56 and the third conveyance roller pair 57, and the conveyance path from the third conveyance roller pair 57 to the sub-scanning roller pair 51 includes: A guide roller 61 is provided, and a movable guide plate 62 is attached so as to be able to move up and down between positions V and W. At position W, the placed sheet S is prevented from coming into contact with the third drive roller 57a. ing. Further, a sheet guide plate 63 is provided behind the sub-scanning roller pair 51.

Note that the sheet S taken out from the supply magazine 52
Even when the leading end of the sheet S reaches the pair of sub-scanning rollers 51, the respective members are arranged at such distances that the trailing end of the sheet S is still held between the pair of first conveying rollers 55.

In the following description, the path along which the sheet S taken out from the supply magazine 52 is fed to the guide plate 63 will be referred to as the first conveyance path, and the guide surface 59c of the resist plate 59 located at the position
The path from the lower end to the guide plate 63 will be referred to as a second conveyance path. That is, the first conveyance path is a path through which the sheet S is pulled out from the supply magazine 52 and goes directly to the sub-scanning roller pair 51, and the second conveyance path is a path through which the sheet S once pulled out passes through the first conveyance path. A path that goes back to the sub-scanning roller 51 for recording after going backwards,
These conveyance paths share a path from the position J of the second driven roller 56b to the guide plate 63.

Next, to explain the operation of this image recording apparatus, the supply magazine 52 in which unrecorded sheets S are stacked and stored is installed at a predetermined position in the apparatus main body, and the slide M52 is placed in a state where the inside of the apparatus is shielded from light. A can be opened. The suction cup 54 is operated to lift the topmost sheet S stacked in the supply magazine 52 to position F.

Next, the first driven roller 55b, which is initially at position G, is moved to position H, and the leading edge of the sheet S is moved to the first conveying roller pair 5.
5. Here, when the first drive roller 55a is rotated clockwise, the sheet S is moved in the direction A,
It is inserted into the pinching roller pair 58. After insertion, when the leading edge of the sheet S moves to a predetermined position, the first drive roller 5
When the first driven roller 55a is stopped and the first driven roller 55b is retracted to position G, the sheet S becomes unrestrained, but is held by the weak frictional force of the nipping roller pair 58 and prevented from falling.

When the resist plate 59 is moved to this position in this state, the resist surface 59b presses against the leading edge of the sheet S, and pushes the sheet S back in the direction B against the weak frictional force of the nipping roller pair 58. At this time, the leading edge of the sheet S follows the resist surface 59b, and the inclination of the sheet S is corrected and the position is aligned. After the above resist operation is completed, the resist plate 59
is returned to the initial position M, the first driven roller 55b is moved to position H again, and the first driving roller 55a is driven until the sheet S passes over the second driven roller 56b initially located at position K. , feeds the sheet S in direction A. Here, when the second driven roller 56b is moved from position K to J, the leading edge of the sheet S is held between it and the second driving roller 56a, and the driving rollers 55a and 56a are rotated, the sheet S is moved to the first position.
is conveyed in the direction C along the conveyance path.

Next, when the leading edge of the sheet S reaches the third conveyance roller pair 57, the third driven roller 57b, which is initially at the position Q,
Sheet S4) With the leading end sandwiched in between, the third drive roller 57a rotates, and the sheet S4 rotates planetarily around the third drive roller 57a in a clockwise direction, and moves to position R. Here, when the revolution of the third driven roller 57b is stopped at position R and the third drive roller 57a continues to rotate, the sheet S is conveyed to the right and inserted into the sub-scanning roller pair 51. Continuing to convey the sheet S, when the sheet S is conveyed until the rear end of the sheet S is removed from the nipping roller pair 58, the resist plate 59 is moved to the position again as shown in FIG.
and reverse the driving rollers 55a, 56a, 57a counterclockwise.

Move the sheet S backward in the direction. That is, the trailing end of the sheet S continues to move backward in descending direction p along the guide surface 59c of the registration plate 59, and when the leading end of the sheet S comes off the sub-scanning roller pair 51, the second driven roller 56b is retracted to position K. At this time, since the sheet S is held between the third pair of transport rollers 57, the drive rollers 55a and 55a again
6a.

When 57a is rotated forward, the sheet S moves along the second conveyance path in direction C.
will be transported to.

When the sheet S continues to be conveyed in the direction C, the leading edge of the sheet S reaches the pair of sub-scanning rollers 51 rotating in the forward direction again, and at the point when the leading edge is sandwiched between the pair of rollers 51, the third driven roller 57b At the same time, the third drive roller 57a stops and the movable guide plate 62 moves to the position W. At this time, the sheet S is placed on the movable guide plate 62, and is moved by the sub-scanning roller pair 51 while the film emulsion surface is in contact with the guide roller 61, so that the sheet S is sub-scanned.

In this way, when the sub-scanning on the sheet S is started, the shutter etc. in the laser optical unit 50 are opened and the main scanning of the laser beam e on the sheet S is started,
A latent image is recorded on the emulsion surface on the upper surface of the sheet S.

The sheet S that is sub-scanned along the second conveyance path is curved along the outer periphery of the movable guide plate 62, but the curve in this part is caused by the repulsive force of the bending of the flexible sheet S and the bending of the sheet S. It is best to create a curve that approximates the natural state in which the forces of sagging due to its own weight cancel each other out. Furthermore, if the sheet S is kept in a natural state without being curved in other parts of the second conveyance path, the frictional resistance between the sheet S and each roller and each guide plate can be reduced. In this way, if the second conveyance path with less frictional resistance is used during sub-scanning, the sheet S to be carried out and the other laminated sheets S left in the supply magazine 52, which occur in the first conveyance path, can be avoided. Frictional resistance caused by static electricity etc. can be prevented. Furthermore, if a straight, uncurved second transport path is selected compared to the first transport path, which has a small radius of curvature of the film transport path, the effect of reducing transport resistance will be further increased. In this way, in this embodiment, sub-scanning can be performed at a stable feed speed with little fluctuation, and a high-quality image without uneven feed can be recorded on the sheet S.

Note that when image recording is completed as described above, the sub-scanning roller pair 51 is reversed to convey the recorded sheet S on the sheet guide plate 63 in a direction opposite to the sub-scanning direction during recording. When the trailing edge of the sheet S reaches the third driving roller 57a again, the movable guide plate 62 returns to position 2, and the retracted third driven roller 57b returns to position R to nip the sheet S. Next, the third driven roller 57b moves the sheet S
As the third drive roller 57a rotates in reverse with the third drive roller 57a sandwiching the
It rotates around the drive roller 57a counterclockwise, passes through position Q, and moves to P.

Here, when the revolution of the third driven roller 57b is stopped at position P and the third drive roller 57a continues to rotate, the recorded sheet S is conveyed and fed into the receive magazine 53 according to the rotation. When the conveyance into the receive magazine 53 is completed, the third driven roller 57b returns to the initial position Q.

Note that here, the number of sheets S already stored in the receive magazine 53 is detected by means not shown,
If the height of the laminated sheet S in the receive magazine 53 is estimated based on the number of sheets, and the stopping position P of the third driven roller 57b is determined according to this height, it is possible to The recorded sheet S can be fed into the receive magazine 53 without malfunction. Also, sheet S
While feeding the sheet S into the receive magazine 53, the third driven roller 57b is gradually moved from the position P in the Q direction, and the angle at which the sheet S enters the receive magazine 53 is controlled to be gradually increased. is also possible.

In addition, by changing the stop position of the third driven roller 57b and changing the conveying direction of the recorded sheet S, the sheet S is not stored in the receive magazine 53, but is placed outside the image recording apparatus, for example. It may also be directly fed to an automatic developing device or the like. That is.

After the recording on the sheet S is completed, the third driven roller 57b
is fixed at position R so that the sheet S is conveyed straight to the left, and a guide plate and a discharge port (not shown) are provided.
If the third drive roller 57a continues to rotate counterclockwise, the recorded sheet S can advance along the guide plate and be fed from the discharge port to the automatic developing device directly connected to the side surface.

Regarding this conveying device, FIGS. 3 and 4 (at
, (bl will provide a detailed explanation of the main parts. In FIGS. 3 and 4 fat, one sheet S is taken out from the supply magazine 52 as described above, and the sheet S is held between the first conveying roller pair 55. The sheet S is conveyed and inserted into the front nipping roller engraving 58.Then, the first driven roller 55b retreats and the sheet S is held only by the nipping roller pair 58.At this time, the nipping roller pair 58 is aligned with the center axis of each other. Assuming that T is the clamping force pushing each other in the direction, μ is the static friction coefficient of the pair of clamping rollers 58, and Ws is the force with which the sheet S tends to come off the pair of clamping rollers 58 due to its own weight, the relationship is μT>Ws. Next, the end of the sheet S is pressed by the resist plate 59 and made to follow the resist surface 59b.At this time, the pressing force with which the resist plate 59 presses the end of the sheet S for correction is F, the coefficient of dynamic friction. If μ° is F+Ws>μT
〉μ°T may be satisfied.

On the other hand, in the case of an arrangement in which the force Ws acts in the opposite direction to the pressing force F as shown in FIG. 59 to press the end of the sheet S and perform a registration operation, the relationship is F-Ws>μT>μ°T.

Here, the weight of the sheet S is generally about 40 g in half-cut film size, and the force Ws that tends to separate the sheet S from the pair of pinching rollers 58 due to its own weight is also small.
The force μT for holding the sheet S needs to be slightly stronger than Ws, and the force for pushing against μT also needs to be weaker.
moves smoothly through the gap between the pair of pinching rollers 58 without causing any scratches. Further, the dynamic frictional force μ°·T generated when the sheet S moves is also a small force and does not apply any rotational force to the pair of pinching rollers 58. Therefore, the sheet S moves by an amount corresponding to the amount pushed by the resist plate 59, and the resist surface 59
Inclination correction will be performed with high precision along the lines. However, in order to prevent the sheet S from being bent when the sheet S is pushed by the resist plate 59, it is desirable that the straightening operation be performed near the pair of pinching rollers 58.

Note that the size of the sheet S that can be used by the conveyance device of the present invention is not limited to one type. That is, since the straightening work is performed at one end of the sheet S, the length of the sheet S on the symmetrical side to the resist plate 59 with respect to the pair of nipping rollers 58 does not matter, so sheets S of various sizes can be used. is possible.

Further, in the above embodiment, the pair of nipping rollers 58 is used as the holding means for the sheet S, but the same effect can be obtained by using a pair of blocks whose surfaces in contact with the sheet S are smoothly finished. Furthermore, a better effect can be obtained by using one-way rollers as the pair of pinching rollers 58. That is, the supply magazine 52
The one-way roller is arranged so that it rotates smoothly in the forward direction with respect to the conveyance direction of the sheet S toward the sub-scanning roller pair 51, and locks in the opposite direction, that is, in the direction in which the sheet S is pushed back by the resist plate 59. do.

In this case, since the one-way roller does not rotate during the registration operation, the sheet S slides on the one-way roller and the inclination is accurately corrected. In addition, a pair of conveying rollers 55
．． 56.57, when conveying the sheet S, the one-way roller rotates in the forward direction and does not damage or apply load to the sheet S.

Note that the scope of application of the present invention is not limited to image recording devices as in the embodiments, but is broadly applicable to devices having a sheet conveyance mechanism for conveying sheet-like members, such as image reading devices, copying devices, and image photographing devices. Of course, it can be applied.

[Advantageous Effects of the Invention 1] As explained above, according to the sheet conveying device according to the present invention, the sheet is held by the holding means that holds the sheet in equilibrium with its own weight, and the sheet straightening means presses the edge of the sheet. By correcting the inclination of the sheet, the inclination can be corrected without bending the sheet, which is accurate, and the sheet will not incline again after correction. Furthermore, since the correction is performed at one end of the sheet, it is possible to correct the inclination of sheets of various sizes with the same arrangement, regardless of the length or width of the sheet.
