Therefore, as shown in FIG. 5, in the printed matter W held by the left and right paper receiving portions 28, 28 above the secondary holding means 24, the distance between the left and right belts 27, 27 is larger than the width of the printed matter W. Since it is quite large, there are variations in the position in the width direction. However, when the belt 27 is driven and the printed matter W held by the paper receiving portion 28 moves downward, the interval between the pair of belts 27, 27 holding the printed matter W gradually narrows, and the held printed matter is held. The position of W in the width direction is corrected. Then, the secondary holding means 24
When the printed material W separates from the paper receiving portion 28 under the belt 27, the distance between the belts 27 and 27 and the width of the printed material W are the same. Therefore, the position where the printed matter W separates from the belt 27 and falls is constant in the width direction of the printed matter W. Therefore, the dropped printed matter W is accurately stored in the discharge tray 40, which will be described later, below the secondary holding unit 24.

The right rotary shaft 21 rotates counterclockwise in synchronization with each other.

Here, the rotary shaft 21 and the rotary shaft 20 are interlocked via gears 29, 31, 32, and the angular velocity ratio between them is:
The rotating shaft 21 is set to "2" while the rotating shaft 21 is set to "1", and the rotating shaft rotates twice while the rotating shaft makes one rotation. These rotary shafts 20 and 21, gears 30 and 3
1, 32, the down motor M2, etc., the primary holding means 2
3 and the drive means of the secondary holding means 24 are constituted.

It should be noted that these may be set to "1: 3". In this case, the interval between the paper receiving portions 28 is 90 degrees,
On the other hand, the distance between the paper receiving portions 28 is set to the pulleys 25, 26.
The rotation angle may be set to 30 degrees, which is 1/3 of the rotation angle on the circle. In addition to this, the angular velocity ratio and the interval (angle) of the paper receiving portion 28 can be appropriately set so as to correspond to each other.

As shown in FIG. 3, a down sensor 35 is provided on the side plate 1b of the frame. The down sensor 35 detects the number of rotations of the rotary shaft 20 by detecting the slit of the rotary plate provided at the end of the rotary shaft 20. The rotation speed of the rotary shaft 20 is determined by the secondary holding means 2.
4 shows the driving amount, that is, the descending amount.

However, the length of the printed matter W is increased between the upper and lower rotary shafts 21 and 22 corresponding to one side edge of the printed matter W. One belt having a sufficient length in the vertical direction may be provided, and a pair of left and right belts may support both side edges of the printed material W.

In the secondary holding means 24 of this embodiment, the diameter of the lower pulley 26 is larger than that of the upper pulley 25. However, the diameter of the upper pulley 25 and the diameter of the lower pulley 26 are the same, and the interval between the pair of left and right rotating shafts 21 and 21 on the upper side is set to be equal to the pair of left and right rotating shafts 22 and 22 on the lower side.
By making it larger than the interval of 22, the interval between the pair of belts 27, 27 corresponding to the left and right side edges of the printed matter W becomes wider than the width of the printed matter W above the belt 27 that receives the printed matter W, and The width of the printed material W may be substantially the same at the lower portion of the belt 27 that discharges W.

Next, the paper discharge tray 40 as a paper stacking / storing device, which is a storage unit for printed matter, will be described.

One outer end of the fence width adjusting plate 46 protrudes from the opening of the guide groove 45 to the side wall 43 side of the box 41 as an operating knob 46a. A pinion 48 is rotatably supported at the center of the bottom surface of the bottom wall portion 42 near the rear wall portion 44. Each fence width adjustment plate 46, 47
Racks are formed at the other inner ends of
The pinions 48 are engaged with each other from opposite sides.

On the bottom wall portion 42, a pair of side fences 49, 49 for guiding both side edges of the printed matter W are installed in parallel with the left and right side wall portions 43, 43, respectively. The side fences 49 are connected to the fence width adjusting plates 46 and 47 via pins 50, respectively. Pin 50
Is inserted through a guide groove (not shown) provided in the bottom wall portion 42 along the left-right direction.

In the above structure, the fence width adjusting plate 4
If you grasp the knob 46a of 6 and put it in and out in the left and right direction,
This fence width adjusting plate 46 and the other fence width adjusting plate 4
7 are interlocked via the pinion 48 and move in opposite directions. Therefore, the pair of side fences 49, 49 connected to the fence width adjusting plates 46, 47 come close to or away from each other in the left-right direction, and thus the pair of side fences depending on the width of the printed matter W to be stored. The interval of 49, 49 can be set arbitrarily.

On the bottom wall portion 42 of the box portion 41, a front fence 51 is provided. Front fence 51
Has a fence plate 52 that guides the front edge of the printed matter W, and a bottom plate 53 that contacts at least a part of the bottom surface of the printed matter W placed in the box portion 41. The fence plate 52 and the bottom plate 53 are integrally formed and intersect at a right angle. Figure 6
In the use state shown in FIG.
And the bottom plate 53 is in contact with the bottom wall portion 42 of the box portion 41.

The front fence 51 includes the side fences 49,
It is attached to the box portion 41 so as to be movable in a direction parallel to the surface of the side wall 49 and rotatable in a plane parallel to the surface of the side fences 49, 49. ing.

The front fence 51 can move back and forth along a rail 54 provided on the bottom wall 42. As shown in FIG. 7, the slider 5 is slidably mounted on the rail 54.
5 is attached. A substantially U-shaped attachment fitting 56 is attached to the slider 55. Slider 5
5 and the mounting member 56 can move together in the longitudinal direction of the rail 54 and can move relative to each other in the vertical direction. A prism 57 is rotatably provided on the upper end of the mounting member 56 via a shaft 58, and a plate spring 59 is provided on the lower end of the mounting member 56. The plate spring 59 is attached from the lower side to the rail 54. The bottom surface of is being pressed.
Therefore, the slider 55 is constantly pressed against the upper surface of the rail 54 by the biasing force of the leaf spring 59.

As shown in FIGS. 7 to 8, a substantially square groove-shaped fixing portion 60 is provided between the fence plate 52 and the bottom plate 53 of the front fence 51. The fixing portion 60 is fixed to the prism 57 of the mounting bracket 56. At the lower corner of the fixed portion 60, the chamfered portion 6 that is approximately 45 ° with respect to the plane of the bottom plate 53 is provided.
1 is formed.

The box portion 41 of the front fence 51 as described above
According to the structure of the holding means, that is, the structure of the rail 54, the slider 55, the mounting bracket 56, the plate spring 59, and the like, the front fence 51 can be moved back and forth along the rail 54, so that the paper discharge tray is provided. It can be set at a position that matches the size of the printed matter W stored in 40 in the front-rear direction. Further, as shown by an arrow A in FIGS. 7 to 8, if the fence plate 52 of the front fence 51 is rotated forward about the shaft 58, the front fence 51 causes the chamfered portion 61 to move to the upper surface of the slider 55. It is stable and can stand still when it is in contact with.

This operation will be described with reference to FIG. 9. From the state shown in FIG. 9A, the shaft 5 is moved to the state shown in FIG. 9B.
The fence plate 52 is rotated counterclockwise in FIG. Since the rail 54 is fixed, the slider 55 provided on the rail 54 cannot move vertically. Therefore, when the chamfered portion 61 of the front fence 51 presses the slider 55, the leaf spring 59 is compressed and the attachment fitting 56 moves upward. Then, the front fence 51 is moved to the slider 5 by the restoring force of the compressed leaf spring 59.
It becomes stable when the chamfered portion 61 is in contact with 5. Inclining the front fence 51 in this way makes it possible to lift the printed matter W placed on the bottom plate 53 of the front fence 51 upward by 45 °, making it easier to take it out.

As described above, the paper discharge tray 40 of the paper discharge device 1 of the present embodiment includes the pair of side fences 49, 49 whose distance can be freely adjusted, and the front fence 51 whose front and rear positions can be freely adjusted. With this, it is possible to set a storage area in the discharge tray 40 that matches the size and shape of the printed matter W to be discharged. Therefore, the printed matter W stored in the paper discharge tray 40 is hard to move in the paper discharge tray 40, and there is no possibility that the printed surface is rubbed and soiled.

Further, it is expected that it is difficult to take out a large number of printed materials W from the storage area in the fence which is set according to the size and outer shape of the printed material W. Since the space between the side fences 49, 49 can be easily widened by operating the fence width adjusting plate 46, and the front fence 51 can be tilted by a simple operation with one hand, it is loaded in the paper discharge tray 40. The printed matter W can be easily taken out.

As shown in FIGS. 3, 4 and 10, an abutting device 70 is provided on the side plate 1b of the frame of the paper discharge device 1. The butting device 70 has a butting plate 71 that is elongated in the longitudinal direction and is substantially rectangular. The lower half of the butting plate 71 is parallel to the vertical plane, and the upper half of the abutment plate 71 constitutes an inclined surface that is slightly inclined upward from the vertical plane with respect to the approach direction of the printed matter W. The printed matter W sent on the endless belt 7 and fed into the apparatus 1 hits the abutting plate 71 and its tip position is regulated, and then rides on the primary holding means 23.

The upper half of the butting plate 71 is inclined because the printed matter W sent from the endless belt 7 of the conveying path 6 is printed.
This is to prevent the rear part from riding on the side plate on the endless belt 7 side as in the printed material W1 shown in FIG.

In this embodiment, the abutting plate 7 is used as described above.
Since the upper half of No. 1 is inclined, the printed matter W that abuts and bounces back tends to be lowered like the printed matter W2 shown in FIG. Similar to the principle that the incident angle and the reflection angle of a sphere hitting a wall are equal, when the printed matter W strikes the inclined butting plate 71 from the horizontal direction, the tip of the printed matter W is slightly recoiled upward. For this reason, the rear part of the printed matter W is lowered, and it is possible to prevent the printed matter W from riding on the transport path 6.

On the back side of the butting plate 71, a pair of left and right arms 72 is provided vertically. One end of an L-shaped link 73 is rotatably connected to a tip of each of the upper and lower arms 72 with a shaft 74. The other end of the link 73 has a shaft 75 and a side plate 1 of the frame.
It is rotatably connected to the b side.

A fan-shaped gear 76 is fixed to each of the upper and lower links 73. A gear 77 meshes with each fan gear 76. Each gear 77 is interlocked with a drive gear 79 via a timing belt 78. The drive gear 79 is driven by an abutting motor M3 provided on the side plate 1b of the frame.

A butting switch 80 is provided below the butting plate 71. When the butting device 70 moves forward and the butting switch 80 comes into contact with the fence plate 52 of the front fence 51 provided on the paper discharge tray 40, the driving of the butting motor M3 is stopped.

As shown in FIGS. 4 and 10, the home sensor 8 is struck at a predetermined position inside the side plate 1b of the frame.
1 is provided. When the abutting plate 71 retracts and returns to the home position, the detection plate 71a provided at the lower end of the abutting plate 71 actuates the abutting home sensor 81, and the abutting home sensor 81 outputs an abutting signal. The driving of the motor M3 is stopped.

In the above structure, the butting motor M3
Driving, the fan gear 76 rotates and the link 73 swings, so that the abutting plate 71 connected to the link 73 is moved to the position shown in FIG.
You can move to the position shown in phantom. The position of the front fence 51 of the paper discharge tray 40 is set variously according to the size of the printed matter W to be stored. According to the abutting device 70, the position of the front fence 51 is detected by the abutting switch 80. Therefore, the abutment plate 71 can always be set accurately at the front end of the storage area set in the paper discharge tray 40.

The printed matter W that has entered from the conveying path 6 hits the inclined abutting plate 71 and therefore does not bounce back and ride on the conveying path 6, and the position in the lengthwise direction is regulated to a predetermined position, and the primary holding means is provided. It is housed in 23.
