  The exclusion members 81 and 82 are rotatably provided on the support shaft 800 of the upper rotary blade 71. That is, the rotation center of the exclusion members 81 and 82 is located in the upper rotary blade 71 when viewed from the width direction, that is, when viewed from the arrow Y direction. The same applies to the cutting machine 7B. Therefore, the exclusion members 81 and 82 can be provided without protruding significantly from the conveyance direction space in which the upper rotary blade 71 is accommodated, and therefore space saving can be realized.

(d-2) Displacement mechanism In the cutting machine 7A, a support shaft 801 and a rotation shaft 802 are provided in parallel with the support shaft 800, and both the shafts 801 and 802 have a cam mechanism 83 for the exclusion member 81, and A cam mechanism 84 for the exclusion member 82 is provided. That is, the displacement mechanism 80 is configured by the support shaft 801, the rotation shaft 802, and the cam mechanisms 83 and 84.

  The cam mechanism 83 includes an eccentric member 831 fixed to the rotation shaft 802 and an arm portion 832 pushed and pulled by the eccentric member 831. The arm portion 832 has a base end 8321 rotatably supported by a support shaft 801, and a tip end 8322 engaged with a pin 8111 on the side surface of the disc body 811. The pin 8111 is inserted into the long hole 8323 of the tip 8322. As a result, the cam mechanism 83 operates as follows. That is, when the rotating body 8324 at the center of the arm part 832 is pushed by the bulging part 8311 of the eccentric member 831, the tip 8322 of the arm part 832 moves downward, and the disk body 811 rotates in the direction of the arrow R 1. The contact portion 812 is a contact position. On the other hand, when the bulging portion 8311 of the eccentric member 831 moves away from the central rotating body 8324 of the arm portion 832, the tip 8322 of the arm portion 832 moves upward and the disk body 811 rotates in the direction of the arrow R <b> 2. Then, the contact part 812 becomes a non-contact position. Here, the contact position of the contact portion 812 is a position where the contact portion 812 contacts the cutting waste on the transport surface 200 from above and guides the cutting waste downward. The non-contact position of the contact portion 812 is a position where the contact portion 812 does not contact the paper on the transport surface 200.

  The cam mechanism 84 includes an eccentric member 841 fixed to the rotation shaft 802 and an arm portion 842 pushed and pulled by the eccentric member 841. The arm portion 842 has a base end 8421 rotatably supported by a support shaft 801 and a tip end 8422 engaged with a pin 8211 on the side surface of the disc body 821. The pin 8211 is inserted into the long hole 8423 of the tip 8422. As a result, the cam mechanism 84 operates as follows. That is, when the rotating body 8424 at the center of the arm portion 842 is pushed by the bulging portion 8411 of the eccentric member 841, the tip 8422 of the arm portion 842 moves downward, and the disk body 821 rotates in the direction of the arrow R1. The contact portion 822 is a contact position. On the other hand, when the bulging portion 8411 of the eccentric member 841 moves away from the central rotating body 8424 of the arm portion 842, the tip 8422 of the arm portion 842 moves upward and the disk body 811 rotates in the direction of the arrow R2. Then, the contact portion 822 becomes the non-contact position. Here, the contact position of the contact portion 822 is a position where the contact portion 822 contacts the cutting waste on the conveying surface 200 from above and guides the cutting waste downward. Further, the non-contact position of the contact portion 822 is a position where the contact portion 822 does not contact the sheet on the transport surface 200.

  As a result, the displacement mechanism configured as described above displaces the operating position of the contact portion 812 of the exclusion member 81 between the contact position and the non-contact position, and the operation position of the contact portion 822 of the exclusion member 82. Also, it is displaced between the contact position and the non-contact position. That is, the displacement mechanism configured as described above is configured to integrally displace the operating positions of the exclusion members 81 and 82.

The displacement mechanism configured as described above is configured so that the operation position X of the contact portion 812 of the exclusion member 81 and the operation position Y of the contact portion 822 of the removal member 82 can be in the following four states. ing.
(1) X is a contact position and Y is a non-contact position (hereinafter referred to as “state 1”),
(2) X is the contact position and Y is the contact position (hereinafter referred to as “state 2”),
(3) X is a non-contact position and Y is a contact position (hereinafter referred to as “state 3”),
(4) X is a non-contact position and Y is a non-contact position (hereinafter referred to as “state 4”).

  The same applies to the cutting machine 7B.

  Specifically, the operating positions X and Y of the exclusion members 81 and 82 are specifically determined by the operating angle α of the bulging portion 8311 of the eccentric member 831, the operating angle β of the bulging portion 8411 of the eccentric member 841, It is determined by the phase difference γ between the protruding portion 8311 and the bulging portion 8411. That is, the operating angle α is an angle of the rotation region of the rotation shaft 802 from when the bulging portion 8311 rotates with the rotation of the rotation shaft 802 until the rotation body 8324 of the arm portion 832 starts to be pushed and finished. is there. The operating angle β is an angle of the rotation region of the rotation shaft 802 until the bulging portion 8411 rotates and starts to push the rotating body 8424 of the arm portion 842 as the rotation shaft 802 rotates. In the displacement mechanism configured as described above, the phase difference γ is set so that the end point of the operating angle α of the bulging portion 8311 coincides with the starting point of the operating angle β of the bulging portion 8411. Thus, when the bulging portion 8311 pushes the rotating body 8324 between the start point and the end point of the operating angle α, the operating position X is in the contact position, but the bulging portion 8411 is within the range of the operating angle β. In other words, since the rotating body 8424 is not pushed, the operating position Y is in the non-contact position. That is, it is in the state 1 described above. Next, when the bulging portion 8311 pushes the rotating body 8324 at the end point of the operating angle α, the bulging portion 8411 also presses the rotating body 8424 at the starting point of the operating angle β. It is in the contact position. That is, it is in the state 2 described above. Next, when the bulging portion 8411 pushes the rotating body 8424 between the start point and the end point of the operating angle β, the operating position Y is in the contact position, but the bulging portion 8311 is within the range of the operating angle α. In other words, since the rotating body 8324 is not pushed, the operating position X is in the non-contact position. That is, it is in the state 3 described above. When the bulging portion 8311 is not within the range of the operating angle α and the bulging portion 8411 is not within the operating angle β, the bulging portion 8311 does not push the rotating body 8324, and the bulging portion 8411 also rotates. Since the body 8424 is not pushed, both the operation position X and the operation position Y are in the non-contact position. That is, it is in the state 4 described above.

As a result, the exclusion member 81 is brought into the contact position. Further, when the first motor 86 is operated and the gear 8831 is rotated by a predetermined amount in the Q2 direction, the exclusion member 81 is moved in the R2 direction via the gear 8821, the rotation shaft 882, the belt transmission mechanism 881, and the rotation shaft 804. As a result, the exclusion member 81 is in the non-contact position.

  In FIG. 11, the exclusion member 82 is provided to be rotatable around the rotation shaft 805. The rotary shaft 805 is positioned parallel to the support shaft 800 of the upper rotary blade 71 and below the support shaft 800 and within the upper rotary blade 71 when viewed from the outside in the width direction, and The upper rotary blade 71 is provided with cantilever support on the outer side in the width direction. The rotating shaft 885 is connected to the rotating shaft 805 via a belt transmission mechanism 884. The rotary shaft 885 is connected to a rotary shaft 886 that receives the drive of a second motor (not shown) via gears 8851 and 8861. Thus, when the second motor is operated and the gear 8861 rotates by a predetermined amount in the Q1 direction, the exclusion member 82 is moved in the R1 direction via the gear 8851, the rotating shaft 885, the belt transmission mechanism 884, and the rotating shaft 805. As a result, the exclusion member 82 is brought into a contact position. When the second motor is operated and the gear 8861 rotates by a predetermined amount in the Q2 direction, the exclusion member 82 passes through the gear 8851, the rotation shaft 885, the belt transmission mechanism 884, and the rotation shaft 805 by a predetermined amount in the R2 direction. As a result, the exclusion member 82 becomes the non-contact position.

  That is, in the present embodiment, the displacement mechanism is constituted by the rotation shafts 804 and 805 and the belt transmission mechanisms 881 and 884, and the displacement drive mechanism is the rotation shafts 882, 85, 885 and 886, gears 8821 and 8831, 8851 and 8861, the 1st motor 86, and the 2nd motor are comprised. The exclusion members 81 and 82 can be independently displaced between the contact position and the non-contact position.

  In the present embodiment, when cutting waste is generated only on the inner side in the width direction of the upper rotary blade 71, the exclusion member 81 is set to the contact position, and the removal member 82 is set to the non-contact position. That is, the state 1 is set. When cutting waste is generated only on the outer side in the width direction of the upper rotary blade 71, the exclusion member 81 is set to the non-contact position, and the rejection member 82 is set to the contact position. That is, the state 3 is set. In addition, when no cutting waste is generated on both sides of the upper rotary blade 71 in the width direction, the exclusion members 81 and 82 are both set to the non-contact position. That is, the state 4 is set. Further, when cutting waste is generated on both sides in the width direction of the upper rotary blade 71, both the exclusion members 81 and 82 are set to the contact positions. That is, the state 2 is set.

According to this embodiment, in addition to the same effects as those of the first embodiment, the following effects can be exhibited.
(I) By appropriately setting the operation amount of the first motor, the contact position of the exclusion member 81 can be finely adjusted, that is, the contact state of the removal member 81 with the cutting waste can be adjusted. The same applies to the exclusion member 82. Therefore, the contact state is changed according to the strength of the paper that becomes the cutting waste, whereby the cutting waste can be removed well and reliably.

<Deformation configuration>
(A) The number of cutting machines included in the cutting unit 51 is not limited to two, and may be one or three or more.
(B) The displacement drive mechanism may be configured to be driven manually without the motor.
(C) The displacement mechanism of the first embodiment may employ another mechanism having the same function, such as a non-circular gear mechanism, instead of the cam mechanism.

(D) The shape of the exclusion member is not limited to the illustrated shape as long as the cutting waste can be guided downward.
(E) The operation panel 60 may not include the display unit 602.
(F) The displacement drive mechanism of the first embodiment may use a cam mechanism or a gear mechanism instead of the belt transmission mechanism.

(G) The displacement mechanism of the second embodiment may use a cam mechanism or a gear mechanism instead of the belt transmission mechanism.
(H) Although it is preferable that the rotation center of the exclusion member is located in the upper rotary blade as viewed from the width direction, it is not always necessary.

(I) The operation position X of the contact portion 812 of the exclusion member 81 and the operation position Y of the contact portion 822 of the exclusion member 82 are at least one of the states 1 and 3 among the above states 1 to 4. It suffices if it can be selectively set to one side and does not necessarily have to be set to state 2 and / or state 4.

  The cutting unit of the present invention can remove cutting waste without moving the cutting machine in the width direction, even if cutting waste is generated on either side of the rotary blade of the cutting machine. Since the cutting waste can be removed immediately after it is generated without moving other members, the industrial utility value is great.
