It is formed at the ends of the suction holes 23 and 23, and when the medium is discharged, the medium is discharged to the suction / discharge port 24, and when the medium is sucked, the customer or the operator can discharge the medium to the suction / discharge port 24. The medium will be inserted. Reference numeral 25 denotes a travel regulation guide, which is operated by a solenoid, which will be described later, so as to draw an arc around the axis of the end portion, and takes either a travel regulation state or an open state.

In this embodiment, the traveling regulation guide 25 is operated around the axis, but if the traveling regulation state and the open state can be reliably set, the traveling regulation guide 25 will be operated in the vertical direction or the horizontal direction. May be. 26 is a shutter,
By the action of the solenoid, which will be described later, the solenoid operates up and down to open and close the conveyance path between the sheet guides 22 and 23.

FIG. 1A shows a state in which a solenoid, which will be described later, is not operating. The traveling regulation guide 25 is in the traveling regulation state, the pressure roller 17 is in a weak pressure state, the shutter 26 is closed, and the pressure roller is closed. 18 is open. FIG. 1B shows a state in which a solenoid, which will be described later, is activated. By the force of this solenoid working by a link mechanism not shown,
The travel regulation guide 25 is in an open state, the pressure roller 17 is in a strong pressure state, the shutter 26 is open, and the pressure roller 18 is in a clamped state.

Reference numeral 27 denotes a stacking unit, which shows a range from the travel regulation guide 25 to the shutter 26 in the transport path between the sheet guides 22 and 23.
The media 7, 8, 9 and 10 will be integrated in 7.
28 is a push-up part, which is a spring material formed in a mountain shape,
The rear ends of the media 7, 8, 9 and 10 conveyed to the stacking unit 27, that is, the inner ends, are pushed up so as to be located above the lower end of the travel regulation guide 25 in the travel regulation state. In the present embodiment, the push-up portion 28 has a chevron shape, but it may have an arc shape, a polygonal shape, or the like, or may be made of plastic or the like as long as the medium can be surely pushed up.

Numerals 29, 30 and 31 are sensors which are provided one above and one below the conveyance path by the sheet guides 22 and 23, detect the passage of the mediums 7, 8, 9 and 10 and transmit them to a control unit which will be described later. It is a thing. FIG. 2 is a simplified block diagram of the embodiment. In the figure, 32 is a control unit and 33 is a solenoid which is a drive source. Although the drive source is a solenoid in this embodiment, a step motor or the like may be used.

The clamped state is released. In this embodiment, the operation of one solenoid 33 is transmitted by a link mechanism so that the travel regulation guide 25, the pressure roller 17, the shutter 26, and the pressure roller 18 are transmitted.
Each member such as is operated, but this may be individually controlled by providing a solenoid for each member.

An example of switching means for switching the pressure roller 17 between a strong pressure state and a weak pressure state will be described below with reference to the drawings. Figure 3
4 is a plan view of the pressure roller 17 of the embodiment, and FIG.
FIG. 3 is an explanatory diagram of a pressure roller 17 of the embodiment. In the figure, reference numerals 34, 35 and 36 denote connecting rods, and the connecting rods 34 and 35 are rotatably connected to each other.
6 is also rotatably connected. The connecting rod 36 is further fixed to a pressure shaft 37, and the pressure shaft 37 is rotatably attached to the apparatus main body.

A pressure arm 38 is rotatably attached to the pressure shaft 37, and the pressure roller 17 is pivotally attached to one end of the pressure arm 38. The other end of the pressure arm has a tension spring 3
Since it is pulled upward by 9, the pressure roller 17 comes into pressure contact with the feed roller 20. This state is a state where the pressure contact force is weak.

Reference numeral 40 is a pin for the pressure shaft 3
It is fixed at 7. Reference numeral 41 denotes a torsion spring, one end of which is fixed to the pin 40 and the other end of which is fixed to the pressure arm 38. When the solenoid 33 operates, the connecting rod 34 is attracted in the direction of arrow C,
The connecting rod 35 is pulled in the direction of arrow C, and the connecting rod 36 and the pressure shaft 37 are moved counterclockwise.

The pin 40 moves with the movement of the pressure shaft 37 to move the end portion of the torsion spring 41 on the pin side counterclockwise, so that the pressure roller 17 side of the pressure arm 38 is attached to the other end of the torsion spring 41. The pressing force acts, and the pressure roller 17 is further pressed against the feed roller 20. As a result, the force of the torsion spring 41 acts on the pressure roller 17 in addition to the force of the tension spring 39. This state is the state of strong pressure contact.

When the operation of the solenoid 33 is stopped, the force of the torsion spring 41 causes the pressure shaft 37 and the connecting rod 36 to move clockwise, and the connecting rod 35.
And 34 will move in the direction of arrow D, and will return to a weak pressure state. In this way, the force of the solenoid 33 is transmitted to the pressure roller 17 by the link mechanism,
The solenoid 33 also acts on the travel regulation guide 25, the shutter 26, and the pressure roller 18 via a link mechanism (not shown).

42 and 43 are drive belts, and 44
Reference numerals 45 denote drive rollers. The driving force of a motor (not shown) works via the driving belt 42 to rotate the driving roller 44. The drive roller 44 drives the drive roller 45 via the drive belt 43, rotates the drive shaft 46, and drives the pressure roller 17.

The pressure roller 17 is not limited to the structure described above, and any mechanism may be used as long as it can switch between a high pressure state and a low pressure state and can drive the pressure roller. The present embodiment having the above-described configuration can be used for both batch discharge of medium and suction of medium. The operation of this embodiment will be described below by dividing it into a batch discharge operation and a suction operation.

Batch Ejecting Operation In FIG. 1A, the media 7 and 8 are accumulated in the accumulating section 27,
Further, the state is shown in which the medium 9 advances to the stacking unit 27. The medium 9 transported in the B direction by a transport unit (not shown) is sandwiched between the pressure roller 16 and the feed roller 19. The feed roller 19 is driven by a motor (not shown) to rotate clockwise, and further conveys the medium 9. The medium 9 advances to the accumulating section 27 through between the travel regulation guide 25 in the travel regulation state and the push-up portion 28.

The media 7 and 8 that have already been conveyed to the stacking unit 27 are sandwiched between the pressure roller 17 and the feed roller 20. The pressure roller 17 and the feed roller 20 are driven by a motor (not shown), the pressure roller 17 rotates counterclockwise, and the feed roller 2
0 rotates clockwise. Since the front ends of the media 7 and 8 are in contact with the shutter 26 and the pressure roller 17 is in a state of weak pressure, the pressure roller 17
Slides on the upper surface of the medium 7 to idle, and the feed roller 20 slides on the lower surface of the medium 8 to idle. This leaves the media 7 and 8 in the stack 27.

The rear ends of the media 7 and 8 are push-ups 28.
It has been lifted by. The medium 9 passes under the travel regulation guide 25, advances along the push-up portion 28, and slides under the medium 8. The end portion of the medium 9 is the feed roller 2
When the medium 9 is nipped by 0, the rotation of the feed roller 20 advances the medium 9 until its end contacts the shutter.
At this time, the upper surface of the medium 9 is in contact with the lower surface of the medium 8, but since the pressure roller 17 is in a state of weak pressure against the feed roller 20, the medium 9 slides under the medium 8 and contacts the shutter 26. You can move on.

After the medium 9 is accumulated in the accumulating section 27, the medium 10 is also similarly conveyed and enters below the medium 9 to be accumulated. When the last one of the mediums to be issued (corresponding to the medium 10 in the figure) is conveyed, passes through the sensor 29 and is accumulated in the accumulating unit 27, the sensor 29 detects the passage of the medium and the control unit 32 determines that all the mediums 7, 8, 9 and 10 to be issued are accumulated in the accumulating unit 27, and actuates the solenoid 33.

The solenoid 33 opens the travel restriction guide 25, sets the pressure of the pressure roller 17 in a strong state, opens the shutter 26, and sets the pressure roller 18 in a clamped state via a link mechanism (not shown).
Since the pressure roller 17 is in a strong pressure state, the media 7, 8, 9 and 10 are not
By the rotation of the feed roller 20 and the feed roller 20, they are collectively conveyed in the state of being gathered toward the suction / discharge port 24, and the shutter 26
It passes under and is sandwiched between the pressure roller 18 and the feed roller 21.

Pressure roller 18 and feed roller 2
1 is in the clamped state so that media 7, 8, 9 and 10
When the trailing ends of the media 7, 8, 9 and 10 pass through the sensor 30, the control unit 32 detects the passage of the medium by the sensor 30, and the control unit 32 stops driving the motor (not shown). And the operation of the solenoid 33 is stopped.

By stopping the operation of the solenoid 33, the traveling regulation guide 25 is in the traveling regulation state, the pressure roller 17 is in a weak pressure state, and the shutter 26 is in the medium 7, 8.
9 and 10 are lightly sandwiched and closed, and the pressure roller 18 is opened. The customer or operator can take out the media 7, 8, 9 and 10 coming out from the intake / outlet port 24 in a collective state.

By taking out the mediums 7, 8, 9 and 10, the shutter 26 is closed and the sensor 31 detects the passage or taking-out of the medium. In the above description, the case where four media are ejected collectively is shown, but the number of media is not limited to four, and a required number of media can be ejected collectively. Further, in the present embodiment, the travel regulation guide 25 is also operated in conjunction with the solenoid 33, but the travel regulation guide 25 may be kept in the travel regulation state at the time of the batch discharge operation. In other words, even if the travel regulation guide 25 is fixed in the travel regulation state, it is possible to perform the batch discharge.

As described above, according to this embodiment, the medium 7,
Since 8, 9, and 10 are discharged in a batch from the top in the order of issue, they are easy to understand and convenient to handle. Further, since the mediums are collectively transported without specially providing a stacker unit for accumulating the mediums, the mounting space can be reduced and the apparatus can be downsized.

Further, by mounting a stapler or other binding tool on the stacking unit 27, it is possible to issue a plurality of media in a bound state. Inhalation Operation FIG. 5 is an explanatory view showing the inhalation operation of the embodiment. FIG. 5A shows a state in which the operator or the customer has inserted the medium 47 from the suction / discharge port 24 in the direction of arrow E.

When the front end of the medium 47 reaches the position of the shutter 26, the sensor 31 detects the presence of the medium, and in response to this, the control section 32 operates the solenoid 33 and drives a motor (not shown). The force of the solenoid 33 operates via a link mechanism (not shown), and as shown in FIG. 5B, the travel regulation guide 25 is opened, the pressure roller 17 is set to a strong pressure state, and the shutter 26 is opened. The pressure roller 18 is clamped.

Further, the driving force of a motor (not shown) is transmitted to the feed rollers 19, 20 and 21 to rotate in the counterclockwise direction and to the pressure rollers 17 and 18 to rotate in the clockwise direction. By setting the pressure roller 18 in the clamped state, the medium 47 is transferred to the pressure roller 1
8 and the feed roller 21 and the pressure roller 1
8 and the feed roller 21 are rotated to be fed into the apparatus.

Since the shutter 26 is in the open state, the medium 47 further advances and is sandwiched between the pressure roller 17 and the feed roller 20. The pressure roller 17 is in a strong pressure state, and the medium 47 is conveyed by the rotation of the pressure roller 17 and the feed roller 20. Since the travel regulation guide 25 is in the open state, the medium 47 further advances and is sandwiched between the pressure roller 16 and the feed roller 19, and the feed roller 19
Is conveyed by rotating. Pressure roller 1
Although the driving force is not applied to 6 but it is rotatable, it comes into contact with the medium 47 to rotate in a clockwise direction to assist the conveyance.

When the rear end of the medium 47 passes through the sensor 29, the sensor 29 detects this passage, and in response to this, the control section 32 stops the operation of the solenoid 33. By stopping the operation of the solenoid 33, the travel regulation guide 25 is in the travel regulation state, the pressure roller 17 is in a weak pressure state, the shutter 26 is closed, and the pressure roller 18 is in the open state, and the suction is completed.

The medium 47 taken in this way is used.
Is further transported to a predetermined position in the medium processing device by a transporting means (not shown). As described above, according to the present embodiment, the medium can be discharged all at once, and the suction process can be performed, and it is not necessary to separately provide a mechanism dedicated to suction.

[0044]

As described above in detail, according to the present invention, it is possible to discharge the media in a piled state from the top in the order in which the media are issued / conveyed. And the effect is particularly effective in a customer-operated device.

Further, since a part of the transport path is used as a medium accumulating section, the medium can be collectively ejected without specially providing a stacker section for accumulating the medium, so that a mounting space can be saved. There is an effect that the number can be reduced and the device can be downsized. In addition, by using a part of the transport path as a medium accumulating section and moving the travel restriction guide, it is possible to perform suction processing without separately providing a mechanism for suction processing or a suction port, and downsizing of the device. And it has the effect of realizing cost reduction.
