Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper receiving device, and more particularly, to a paper receiving device that aligns paper discharged from a paper processing machine.
[0002]
[Prior art]
A paper receiving device as shown in FIGS. 1 and 2 is mounted on a paper processing machine such as an image forming machine such as a stencil printing machine or a copying machine, or a cutting machine. (For example, JP-A-11-138966)
[0003]
In the paper receiving apparatus shown in FIGS. 1 and 2, the pair of left and right side guide plates 114 provided on the top plate 110 or the paper receiving base 112 reciprocate left and right in accordance with the timing of paper discharge 109, that is, jogger operation. As a result, the stacked paper discharges 109 are aligned in the paper width direction.
[0004]
In the paper receiving apparatus, the left and right side guide plates 114 themselves reciprocate between the side contact position and the side retracted position as a whole. Therefore, when the side guide plate 114 is in the side retracted position, a wide gap 113 is formed between the side surface of the side guide plate 114 and the side surface of the stacked paper discharge 109. As a result, the paper discharge 109 falls into the gap 113 depending on the type of paper (for example, thin paper that tends to have curl inside) and the printing status of the paper (for example, paper that is solidly printed on the left and right sides of the paper). It may be. Since the next paper discharge 109 is stacked on the paper discharge 109 dropped into the gap 113, the paper discharge 109 dropped into the gap 113 does not return to the normal stacking position by the jogger operation. Therefore, the paper receiving apparatus according to the prior art has a problem that it is impossible to neatly arrange a large amount of paper discharged from the paper processing machine.
[0005]
[Problems to be solved by the invention]
Therefore, a technical problem to be solved by the present invention is to provide a paper receiving device for neatly aligning a large amount of paper discharged from a paper processing machine.
[0006]
[Means / Actions / Effects to Solve Problems]
In order to solve the above technical problem, a paper receiving apparatus according to the present invention includes left and right side guide plates for positioning paper discharge in a paper width direction orthogonal to a paper discharge direction in which paper is discharged from a paper processor. A front stop plate that is provided in front of the paper discharge direction and receives paper discharged from the paper processor, and at least one of the left and right side guide plates has a side regulating plate and a side movable plate, The side regulating plate is positioned at a side abutting position where it abuts on the side surface in the width direction of paper discharge, while the side surface movable plate is positioned outside the side surface abutting position and the side surface abutting position in the paper ejection width direction. It is characterized by performing a jogger operation by reciprocating between the side retracted position.
[0007]
According to the above configuration, the paper discharged from the paper processing machine and flying is conveyed to the front end side in the paper discharge direction while being guided by the side surface regulating members of the left and right side guide plates. The discharged paper is received by a front stop plate provided on the front end side in the paper discharge direction, and then landed on the paper receiving base of the paper receiving device. Since the side end face of the paper discharged on the paper receiving tray is held by the left and right side guide plates, there is no gap between the side end face of the paper discharge and the side guide plate. Accordingly, the discharged paper does not enter the gap. For the paper held by the left and right side guide plates, the side movable plates of the left and right side guide plates reciprocate between the side contact position and the side retraction position to perform a jogger operation in the paper width direction. As a result, the side movable plate has an action of pushing the end face of the discharged paper riding on the side regulating plate in an irregular state into the inside, and the sheets can be neatly aligned. The irregular paper discharge is regulated by the side regulation plate, so the part that contacts the side movable plate seems to be small, but the actual paper is curved flexibly, so only the irregular part is the only part of the side regulation plate. By projecting outward, the side movable plate effectively pushes only that portion, and the paper discharge is neatly aligned. In addition, even when the paper discharge lands diagonally with respect to the paper cradle and the corner of the paper discharge rides on the side regulating plate, the side movable plate will jog. As a result, the discharged paper discharge corner portion is pushed back toward the center, and the side end surfaces of the paper discharge are orderly aligned.
[0008]
Preferably, in the side guide plate having the side regulation plate and the side movable plate, the side regulation plate and the side movable plate are aligned in a straight line in the paper discharge direction at the side contact position, Side movable plates are arranged on both sides of the plate.
[0009]
In the side guide plate, the side regulating plate and the side movable plate are aligned in a straight line in the paper discharge direction at the side contact position, and the side movable plate is arranged on both sides of the one side regulating plate. Therefore, the paper discharge held by the side regulating plate is greatly swung from the central side regulating plate by the side movable plates arranged on both sides thereof, so the jogger operation is more effective Become.
[0010]
The side guide plate and the front stop plate can be configured to extend upward while being disposed on the paper tray on which the paper is stacked.
[0011]
Further, the side guide plate and the front stop plate may be arranged on a top plate arranged directly above the paper cradle and extend toward the paper cradle.
[0012]
In the paper tray in which the side guide plate and the front stop plate are disposed on the top plate, it is preferable that a predetermined discharge stacking level is maintained by appropriately lowering the paper tray.
[0013]
According to the above configuration, since the landing position of the paper discharge is substantially constant, the placement of the paper discharge is stable, and the condition of the paper discharge is further improved.
[0014]
Preferably, the front stop plate includes a front regulating member and a front movable plate, and the front regulating member is positioned at a front contact position where the front regulating member contacts the front surface in the length direction of the paper discharge. A jogger operation is performed by reciprocating between the front surface contact position and a front surface retraction position positioned forward of the front surface contact position in the paper discharge length direction.
[0015]
According to the above configuration, like the side guide plate described above, the front movable plate of the front stop plate reciprocates between the front contact position and the front retraction position to perform a jogger operation in the paper length direction. The front end face of the paper is also neatly aligned.
[0016]
Depending on the size of the paper, the user can manually move the side guide plate and the front stop plate to the predetermined contact positions. Preferably, the side guide plate and the front stop plate are the size of the paper. In response to this, each is automatically moved to a predetermined contact position. Therefore, the user does not have to be bothered by the positioning setting of the side guide plate and the front stop plate, and the convenience for the user is enhanced.
[0017]
In order to move the side guide plate and the front stop plate to a predetermined contact position, the side regulating plate and the side movable plate, or the front regulating member and the front movable plate are respectively separated by a belt wound between a pair of pulleys. Driven by a supported drive mechanism, each of the drive mechanisms has substantially the same configuration.
[0018]
According to the above configuration, since the drive mechanisms of the side guide plate and the front stop plate are substantially the same configuration, simplification of the drive mechanism and common use of the members are achieved. Therefore, it is possible to quickly cope with a design change, it becomes easy to manage the used members, and the cost can be reduced.
[0019]
For example, if the jogger operation is not performed for paper that does not require paper alignment, such as thick paper, the operation sound generated during the jogger operation can be eliminated, so the presence or absence of the jogger operation can be selected. Preferably there is. Therefore, noise reduction of the paper receiving device is realized.
[0020]
When the jogger operation is unnecessary, the movable plate is fixedly positioned at the contact position. Therefore, the paper receiving apparatus according to the present invention can be used as a paper receiving apparatus that does not perform a jogger operation.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the paper receiving apparatus 1 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 3, 4, 6 to 12 and 17.
[0022]
FIG. 3 is an explanatory view of the paper receiving device 1 incorporated in the stencil printing machine 2 which is a paper processing machine as viewed from the side. As shown in FIG. 3, the paper receiving apparatus 1 is disposed adjacent to the right side of the stencil printing machine main body, and the paper 9 sequentially discharged from the paper discharge unit 3 of the stencil printing machine 2 is directed to the paper receiving tray 12. After flying, they land on the paper tray 12 and can be stacked. Note that the paper processing machine is an image forming machine such as a stencil printing machine or a copying machine, a paper cutting machine that cuts continuous paper into paper of a predetermined size, a contact letter manufacturing machine that folds predetermined paper to form a contact letter, etc. It means various machines that sequentially discharge a predetermined size of paper from the paper discharge unit 3.
[0023]
The paper receiving apparatus 1 includes a top plate 10 that is pivotally supported by a shaft 11 at the right end of the stencil printing machine 2 and positioned at a horizontal position (solid line) and an inclined position (two-dot chain line), It has a paper tray 12 on which the paper 9 is loaded and an elevator device that moves the paper tray 12 up and down. Therefore, the paper receiving apparatus 1 according to the first embodiment is of a top plate installation type in which the jogger mechanism is provided on the top plate 10. In addition, the thing of the top plate installation type provided with an elevator apparatus can respond | correspond to the stack | stacking of the continuous and many discharges 9 by lowering an elevator apparatus.
[0024]
The flat top plate 10 having a certain thickness includes a pair of left and right separation-type side guide plates 20 provided at both end portions in the paper width direction orthogonal to the paper discharge direction 90, and a front of the paper discharge direction 90. The provided separation type front stop plate 30 is disposed.
[0025]
The plate-shaped left and right side guide plates 20 extending in parallel along the paper discharge direction 90 extend toward the paper tray 12, that is, substantially vertically downward when the top plate 10 is in the horizontal position. Yes. As shown in FIGS. 3 and 4, the left and right side guide plates 20 include a substantially L-shaped side regulating member 22 in which two narrow side regulating plates 22 a and 22 b are integrally connected at the top, and three wide sides. The side movable plates 24a, 24b, and 24c are formed of a substantially L-shaped side movable member 24 integrally connected at the upper part. The side guide plate 20 shown in FIG. 4 is arranged in the order of the side movable plate 24a, the side regulating plate 22a, the side movable plate 24b, the side regulating plate 22b, and the side movable plate 24c along the paper discharge direction 90. 24 a, 22 a, 24 b, 22 b, 24 c is a five-sheet configuration in which each plate-like body 24 a, 22 a, 24 b, 22 b, 24 c is exposed from the guide groove 15 provided on the lower surface of the top plate 10. ing.
[0026]
The side regulating plates 22 a and 22 b are for regulating the side position of the paper discharge 9, and do not require a particularly wide width. However, the side movable plates 24 a, 24 b and 24 c are provided on the side of the paper discharge 9. Since it is for pushing and aligning, the one where a width dimension is wide is preferable. Further, since the side movable plates 24a, 24b, 24c are arranged on both sides of the side regulating plates 22a, 22b holding the paper discharge 9, the side movable plates based on the side regulating plates 22a, 22b are disposed. Since the moment of oscillation by 24a, 24b, and 24c increases, the jogger operation becomes more effective.
[0027]
The side regulating member 22 and the side movable member 24 are separately supported so as to be movable in a direction orthogonal to the paper discharge direction 90 (the direction perpendicular to the paper surface in FIG. 3), and details of their driving mechanism and operation will be described later.
[0028]
The front stop plate 30 extending in parallel along the direction orthogonal to the paper discharge direction 90 extends toward the paper receiving tray 12, that is, substantially vertically downward when the top plate 10 is in the horizontal position. . As shown in FIGS. 3 and 4, the front stop plate 30 has a substantially L-shaped front surface in which one substantially L-shaped front regulating member 32 and two front movable plates 34a and 34b are integrally connected at the upper part. The movable member 34 is constituted. The front movable plates 34a and 34b are disposed on both sides of the front regulating member 32 disposed substantially at the center in the width direction of the paper discharge 9 in parallel along the direction perpendicular to the paper discharge direction 90, that is, the front movable plate. 34a, the front regulating member 32, and the front movable plate 34b are arranged in an exposed manner from the guide groove 15 provided on the top plate 10. The front regulating member 32 and the front movable member 34 are separately supported so as to be movable in the paper discharge direction 90 (left and right direction in FIG. 3), and details of their driving mechanisms and operations will be described later. Further, a columnar abutting member 13 extending in a substantially vertical direction is disposed at a predetermined position on the stencil printing machine 2 side, and the jogger operation for the front stop plate 30 is performed by the abutting member 13. Done to the standards.
[0029]
The paper receiving tray 12 is a substantially flat plate that is below the paper discharge unit 3 of the stencil printing machine 2 and extends in the paper discharge direction 90 (left-right direction in FIG. 3). The paper receiving tray 12 is connected to an elevator apparatus configured as follows, and can stack a large amount of paper discharge 9.
[0030]
One end of the chain 6 is fixed to the side surface of the paper tray 12. The chain 6 is bent by the sprockets 5 and 7, and the other end of the chain 6 is always pulled by the tension spring 8. The sprocket 5 is rotated by the lift motor 4 and the chain 6 is moved, so that the paper tray 12 can be lifted and lowered. The upper limit position and the lower limit position of the paper tray 12 are detected by an upper limit switch and a lower limit switch, respectively. The paper cradle 12 supported by the elevator device so as to be movable up and down is raised to a position indicated by a two-dot chain line at the start of printing. The level sensor 17 detects the height of the paper discharge 9 loaded on the paper tray 12 (the highest paper discharge stacking position). When the paper discharges 9 are sequentially stacked on the paper receiving tray 12, the paper receiving tray 12 is gradually lowered so that the stacking position of the uppermost paper discharge 9 on the paper receiving tray 12 is within a predetermined range. It is like that.
[0031]
Next, the drive mechanism of the left and right side guide plates 20 disposed on the top plate 10 will be described with reference to FIGS.
[0032]
Both ends of the left and right side guide plate shafts 47 are fixed by shaft fixing members 46, respectively. The slide member 64 is inserted into the side guide plate shaft 47 and slides along the side guide plate shaft 47. The side regulating member belt 41 is wound around a pair of left and right pulleys 49. The rotation shaft of the side regulating member motor 51 (for example, a stepping motor) is meshed with a gear 61 that is passed through a shaft 62 that is disposed adjacently. The shaft 62 is passed through one pulley 49. Therefore, the right side pulley 49 that is rotationally driven by the side surface regulating member motor 51 causes the side surface regulating member belt 41 to circulate between the left and right pulleys 49 in both directions.
[0033]
As shown in FIG. 7, a slide member 64 is connected to the upper part of the side surface regulating member 22 located on the left side. The belt connecting portion 66 at the upper portion of the slide member 64 is connected and fixed to the upper surface of the side regulating member belt 41 wound around a pair of pulleys 49. On the other hand, the slide member 64 is also connected to the upper part of the side surface regulating member 22 located on the right side. The belt connecting portion 66 at the upper part of the slide member 64 is connected and fixed to the lower surface of the side regulating member belt 41 wound around a pair of pulleys 49. Therefore, the movement of the left and right side surface regulating members 22 is interlocked with the movement of the side surface regulating member belt 41. For example, when the side surface regulating member belt 41 rotates clockwise, the left and right side surface regulating members 22 approach each other, When the side regulating member belt 41 rotates counterclockwise, the left and right side regulating members 22 are driven so that the left and right side regulating members 22 are separated from each other.
[0034]
As shown in FIGS. 6 and 7, the drive mechanism of the side regulating member 22 is provided with a rotary encoder. In other words, the rotary slit plate 58 is coupled to the rotating shaft of the side regulating member motor 51, and the photo interrupter 57 is disposed so as to face the rotary slit plate 58. The rotary slit plate 58 has pulse marks arranged radially. The photo interrupter 57 detects the passage of the pulse mark on the rotary slit plate 58 and generates a pulse signal.
[0035]
Further, a light shielding plate 63 is fixed to each of the side surface regulating members 22, and a photo interrupter 56 is appropriately disposed on the top plate 10. The light shielding plate 63 is configured to shield the photo interrupter 56 when the side surface regulating member 22 is at the home position (the outermost position in FIG. 6).
[0036]
When each side regulating member 22 of the left and right side guide plates 20 is located at the home position, when a driving pulse is applied from a driving circuit (not shown), the side regulating member motor 51 rotates at a predetermined rotational speed, Each side regulating plate 22a, 22b moves to a predetermined side contact position while approaching the same distance in the relative direction. As a result, as shown in FIG. 9, the pair of left and right side surface regulating plates 22a and 22b are positioned at a predetermined side surface contact position, that is, at the side end surface position in the width direction of the paper to be used. Temporarily fixed. Accordingly, there is no gap between the side surface of the stacked paper discharge 9 and the inner side surfaces of the side surface regulating plates 22a and 22b of the side guide plate 20, so the paper discharge 9 from the stencil printing machine 2 is the gap. I don't get into it. Note that the side surface regulating plates 22a and 22b are automatically moved to the corresponding side surface contact positions according to the size of the paper 9 to be discharged.
[0037]
Similarly to the side surface regulating member 22, the side surface movable member 24 of the side surface guide plate 20 is driven.
[0038]
That is, as shown in FIG. 6, the slide member 64 is connected to the upper part of the side surface movable member 24 located on the left side. An upper belt connecting portion of the slide member 64 is connected and fixed to the upper surface of the side movable member belt 42 wound between a pair of pulleys 49. On the other hand, a slide member 64 is connected to an upper portion of the side movable member 24 located on the right side. The upper belt connecting portion of the slide member 64 is connected and fixed to the lower surface of the side movable member belt 42 wound between the pair of pulleys 49. Therefore, the movement of the left and right side movable members 24 is linked to the movement of the side movable member belt 42. For example, when the side movable member belt 42 rotates clockwise, the left and right side movable members 24 approach each other, When the side movable member belt 42 rotates counterclockwise, the left and right side movable members 24 are driven so that the left and right side movable members 24 are separated from each other.
[0039]
The drive mechanism of the side movable member 24 is also provided with a rotary encoder. That is, the rotary slit plate 58 is coupled to the rotating shaft of the side surface movable member motor 52, and the photo interrupter 57 is disposed so as to face the rotary slit plate 58. The rotary slit plate 58 has pulse marks arranged radially. The photo interrupter 57 detects the passage of the pulse mark on the rotary slit plate 58 and generates a pulse signal.
[0040]
Further, a light shielding plate 63 is fixed to each of the side surface movable members 24, and a photo interrupter 56 is appropriately disposed on the top plate 10. The light shielding plate 63 is configured to shield the photo interrupter 56 when the side surface movable member 24 is at the home position (the outermost position in FIG. 6).
[0041]
When each side movable member 24 of the left and right side guide plates 20 is at the home position, when a drive pulse is given from a drive circuit (not shown), the side movable member motor 52 rotates in the forward direction at a predetermined number of rotations. Thus, the left and right side movable plates 24a, 24b, and 24c move in a short time to a predetermined side contact position while approaching the same distance in the relative direction. As a result, the left and right side movable plates 24a, 24b, and 24c abut against the both side surfaces of the paper discharge 9 that are already held by the left and right side surface regulating plates 22a and 22b, so that the positional deviation in the width direction of the paper discharge 9 occurs. Will be corrected. At this time, the side regulating plates 22a and 22b and the side movable plates 24a, 24b, and 24c are aligned and arranged in a substantially straight line as seen in a plan view, as shown in FIG. 8B. Note that the side movable plates 24a, 24b, and 24c are automatically moved to the corresponding side contact positions according to the size of the paper 9 to be discharged.
[0042]
When the drive pulse is given from a drive circuit (not shown), the side surface movable member motor 52 rotates in the reverse direction at a predetermined rotation number, and as shown in FIG. 24 move in a short time to a predetermined side retraction position located outside the side surface contact position while being separated by an equal distance (that is, simultaneously). Further, a drive pulse is given from a drive circuit (not shown), and the side surface movable member motor 52 rotates in the forward direction at a predetermined number of rotations, so that each side surface movable member 24 is equidistant as shown in FIG. Is moved in a short time to the original side contact position while approaching in the relative direction. As a result, the left and right side movable plates 24a, 24b, and 24c come into contact with both side surfaces of the paper discharge 9 held by the left and right side surface regulating plates 22a and 22b. The positional deviation in the width direction of the paper 9 is corrected. As described above, the left and right side movable plates 24a, 24b, and 24c reciprocate between the side surface contact position in FIG. 8 and the side surface retracted position in FIG. 9 to perform a jogger operation in the paper width direction. Both end faces of 9 are neatly aligned.
[0043]
In addition, as shown in FIG. 17, the discharge 9 discharged from the discharge direction 90 lands diagonally with respect to the paper cradle, and the diagonal of the discharged paper 9 'lands diagonally. There may be a case where the position corner portion 9'a rides on the side regulating plates 22a and 22b and is largely displaced. Even in this case, when the side movable plates 24a, 24b, and 24c perform the jogger operation in the paper width direction, the discharged paper discharge 9 ′ corner portion 9′a is pushed back toward the center, and the paper discharge 9 The side edges of the are aligned in an orderly manner.
[0044]
When the side guide plate 20 and the front stop plate 30 are automatically moved to predetermined contact positions according to the paper size, for example, the side regulating member 22 and the side movable member 24 of the side guide plate 20 are respectively Simultaneously move from each home position to a predetermined position.
[0045]
Next, the drive mechanism of the front stop plate 30 disposed on the top plate 10 will be described with reference to FIGS.
[0046]
Both ends of the front stop plate shaft 48 extending in parallel to the paper discharge direction 90 are fixed by shaft fixing members 46, respectively. The slide member 64 is inserted through the front stop plate shaft 48 and slides along the front stop plate shaft 48. The front regulating member belt 43 is wound around a pair of front and rear pulleys 49. The rotation shaft of the front regulating member motor 53 (for example, a stepping motor) is engaged with a gear 61 that is passed through the shaft 62. The shaft 62 is passed through a pulley 49 on the rear side. Therefore, the front regulating member belt 43 circulates between the pair of front and rear pulleys 49 in both directions by the rear pulley 49 that is rotationally driven by the front regulating member motor 53.
[0047]
A front regulating member 32 is provided in front of the paper discharge direction 90, and a slide member 64 is connected to the top of the front regulating member 32. The upper belt connecting portion of the slide member 64 is connected and fixed to either the upper surface or the lower surface of the front regulating member belt 43 wound between the pair of pulleys 49. Accordingly, the movement of the front regulating member 32 is interlocked with the movement of the front regulating member belt 43. For example, when the front regulating member belt 43 rotates clockwise, the front side regulating member 32 moves forward in the paper discharge direction 90. When the leading end regulating member belt 43 rotates counterclockwise, the front regulating member 32 moves rearward in the paper discharge direction 90.
[0048]
The drive mechanism of the front regulating member 32 is provided with a rotary encoder. In other words, the rotary slit plate 58 is coupled to the rotating shaft of the front regulating member motor 53, and the photo interrupter 57 is disposed opposite the rotary slit plate 58. The rotary slit plate 58 has pulse marks arranged radially. The photo interrupter 57 detects the passage of the pulse mark on the rotary slit plate 58 and generates a pulse signal.
[0049]
Further, a light shielding plate 63 is fixed to the front regulating member 32, and a photo interrupter 56 is appropriately disposed on the top plate 10. The light blocking plate 63 is configured to block the photo interrupter 56 when the front regulating member 32 is at the home position (the most advanced position in the paper discharge direction 90 in FIG. 6).
[0050]
When the front regulating member 32 is at the home position and a driving pulse is given from a driving circuit (not shown), the front regulating member motor 53 rotates in the positive direction at a predetermined number of rotations, and the front regulating member 32 It moves to a predetermined front surface contact position (front end surface position in the length direction of the used paper) and is temporarily fixed at this front surface contact position. Accordingly, there is no gap between the front surface of the stacked paper discharge 9 and the inner surface of the front regulating member 32 of the front stop plate 30, so that the paper discharge 9 from the sheet processing apparatus 2 enters this gap. There is no. The front regulating member 32 is automatically moved to the corresponding front abutting position according to the size of the paper 9 to be discharged.
[0051]
The front movable member 34 of the front stopper plate 30 is driven in the same manner as the front regulating member 32.
[0052]
That is, as shown in FIG. 6, the slide member 64 is connected to the upper portion of the front movable member 34 located in front of the paper discharge direction 90. The upper part of the slide member 64 is connected and fixed to either the upper surface or the lower surface of the front movable member belt 44 wound between a pair of pulleys 49. The movement of the front movable member 34 is linked to the movement of the front movable member belt 44. For example, when the front movable member belt 44 rotates clockwise, the front movable member 34 is directed forward in the paper discharge direction 90. When the front movable member belt 44 moves and rotates counterclockwise, the front movable member 34 moves rearward in the paper discharge direction 90.
[0053]
The drive mechanism for the front movable member 34 is also provided with a rotary encoder. In other words, the rotary slit plate 58 is coupled to the rotating shaft of the front movable member motor 54, and the photo interrupter 57 is disposed so as to face the rotary slit plate 58. The rotary slit plate 58 has pulse marks arranged radially. The photo interrupter 57 detects the passage of the pulse mark on the rotary slit plate 58 and generates a pulse signal.
[0054]
Further, a light shielding plate 63 is fixed to the front movable member 34, and a photo interrupter 56 is disposed at an appropriate position on the top plate 10. The light shielding plate 63 is configured to shield the photo interrupter 56 when the front movable member 34 is at the home position (the most advanced position in FIG. 6).
[0055]
When each front movable member 34 of the left and right side guide plates 20 is at the home position, when a drive pulse is applied from a drive circuit (not shown), the front movable member motor 54 rotates in the forward direction at a predetermined number of rotations. Thus, the front movable plates 34a and 34b move to a predetermined front surface contact position in a short time. As a result, the front movable plates 34 a and 34 b come into contact with the front surface of the paper discharge 9 already positioned by the front regulating member 32 and the abutting member 13, so that the paper discharge 9 placed on the paper receiving tray 1 is placed. The positional deviation in the length direction is corrected. Note that the front movable plates 34a and 34b are automatically moved to the corresponding front contact positions according to the size of the paper 9 to be discharged.
[0056]
When a driving pulse is given from a driving circuit (not shown), the front movable member motor 54 rotates in the reverse direction at a predetermined rotational speed, and the front movable member 34 at the front contact position is moved from the front contact position. It moves in a short time to a predetermined front surface retraction position located in front of the paper discharge direction 90. Further, a driving pulse is given from a driving circuit (not shown), the front movable member motor 54 rotates in the forward direction at a predetermined number of rotations, and the front movable member 34 moves to the original front contact position in a short time. Moving. As a result, the front movable plates 34 a and 34 b abut on the paper discharge 9 positioned by the front regulating member 32 and the abutting member 13, and thereby the length direction of the paper discharge 9 placed on the paper receiving tray 1. The misalignment is corrected.
