As shown in FIGS. 7 and 8, the rotation center X is substantially the center of the raised bottom 18. The raised bottom 18 is horizontally disposed on the upper surface 18e. On the upper surface 71e of the turntable 71, three blades 71h extending radially from the rotation center X in a rotationally symmetrical manner are attached so as to protrude from the upper surface 71e. Further, as indicated by a broken line in FIG. 8, a gear 71 g (second transmission member) is attached to the lower surface 71 f of the turntable 71. Since the rotary table 71 is given a rotational force via the gear 71g, the intersection of the rotary shaft of the gear 71g and the substrate table 71 is the rotation center X.

  The rotary arm 72 (first transmission member) and the gear plate 73 (third transmission member) are mechanisms (power transmission mechanisms) for transmitting power generated by opening and closing the lower door 14 and rotating the rotary table 71. . As shown in FIG. 7, a rotating arm 72 is disposed below the raised bottom 18, and a gear plate 73 is disposed below the rotating arm 72. The rotary arm 72, the gear plate 73, and the lower door 14 are attached to the housing 10 on an axis Y that extends in the vertical direction, and can rotate about the axis Y, respectively.

  FIG. 9 is a perspective view of the raised bottom 18, the rotary table 71, and the lower door 14, and the rotary table 71 configured by the rotary arm 72, the gear plate 73, the arm 142 attached to the lower door 14, and the rod 143 is rotated. It is the figure which paid its attention to the mechanism for this. As shown in FIG. 9, the rotary arm 72 includes an arm portion 721 extending in the left-right direction and a blade portion 722 integral with the arm portion 721. The blade portion 722 extends from the rear surface 721b of the arm portion 721 in the vicinity of the right end 721d of the arm portion 721. The shape of the blade portion 722 is arbitrary, but in the present embodiment, the blade portion 722 has a substantially fan shape in plan view. Yes. The arm portion 721 has a hole 721h in the vicinity of the left end 721c, and the blade portion 722 has a groove 722g. The groove 722g has an arc shape centered on the axis Y.

  The gear plate 73 includes a sector gear 731 and a protrusion support portion 732. The sector gear 731 has gear teeth 731 g on its peripheral wall, and the gear teeth 731 g mesh with the gear 71 g of the rotary table 71. The protrusion support portion 732 has a protrusion 732 p, and the protrusion 732 p is engaged with the groove 722 g of the rotating arm 72.

  On the rear surface 14b of the lower door 14, a lever 142, a rod 143, and a guide plate 144 are provided. The lever 142 is connected to the handle 141 by a shaft extending through the front surface 14 a and the rear surface 14 b of the lower door 14. The rod 143 is a long rod-like member extending substantially in the vertical direction. The rod 143 is rotatably connected to the lever 142 in the vicinity of the upper end, and is slidably held in the hole 144h of the guide plate 144 provided in the rear surface 14b of the lower door 14 in the vicinity of the lower end. According to the above configuration, when the handle 141 of the lower door 14 is rotated, the lever 142 rotates integrally, and the rod 143 rotatably connected to the lever 142 moves in the vertical direction.

  FIG. 10A shows a state in which the lower door 14 with the handle 141 positioned in the vertical direction is viewed from the front side, and FIG. 10B shows the lower door 14 in the same state on the rear side. It shows how it looked more. At this time, the lower end 143f of the rod 143 is positioned above the rotating arm 72, and the rod 143 is not inserted into the hole 721h of the rotating arm 72. If the lower door 14 is opened in this state, the lower door 14 is only rotated.

  FIG. 10C shows a state where the lower door 14 in a state in which the handle 141 is rotated counterclockwise is viewed from the front side, and FIG. 10D shows the lower door 14 in the same state on the rear side. It shows how it looked more. At this time, the lower end 143 f of the rod 143 is positioned below the rotating arm 72. That is, the rod 143 is inserted into the hole 721 h of the rotating arm 72. If the lower door 14 is opened in this state, the rotating arm 72 rotates as the lower door 14 rotates.

  According to the rotating mechanism 7 described above, when the handle 141 of the lower door 14 is operated to open the lower door 14 with the rod 143 being inserted into the hole 721h of the rotating arm 72, the lower door 14 is rotated. The arm 72 rotates and the rotary table 71 rotates. Details of the operation will be described later.

  Next, operation | movement of the shredder 1 of this embodiment is demonstrated.

  When cutting the object to be cut using the shredder 1 of the present embodiment, the object to be cut is input from the input port 11 (FIG. 2). The workpiece to be cut is finely cut by the cutting mechanism 2 and accumulated in the waste bag B as cut waste W (FIG. 2). When the cutting waste W in the waste bag B reaches a predetermined amount, the shredder 1 detects this using a sensor (not shown) and informs the user that the cutting waste W needs to be discarded. This transmission is performed, for example, by displaying a message prompting the operation unit 12 to discard the cutting waste W or sounding an alarm sound. In the following description, the waste bag B in which the cutting waste W reaches a predetermined amount and needs to be discarded is referred to as a waste bag B1.

<Torsion imparting action>
FIG. 11A shows a shredder 1 that houses a waste bag B1 that needs to be discarded. When the shredder 1 is in this state, the user first rotates the handle 141 (FIG. 10A) of the lower door 14 counterclockwise (FIG. 10C). As shown in FIG. 10D, this causes the rod 143 of the lower door 14 to engage with the hole 721 h of the rotating arm 72 of the rotating mechanism 7. When the lower door 14 is rotated about the axis Y in this state and the door is opened, the rotary arm 72 also rotates about the axis Y together with the lower door 14.

  12A and 12B show how the rotary arm 72 rotates. FIG. 12A shows a state before the rotating arm 72 rotates, and FIG. 12B shows a state after the rotating arm 72 rotates. In FIG. 12A, when the rotary arm 72 is rotated integrally with the lower door 14, the rotary arm 72 rotates about the axis Y in the direction of the arrow c. At this time, the groove 722g provided in the blade portion 722 of the rotary arm 72 also rotates about the axis Y. Here, since the groove 722g is formed in an arc shape having a constant distance from the axis Y, if the rotation amount of the rotary arm 72 is small, the protrusion 732p of the gear plate 73 only moves relatively in the groove 722g. Thus, the rotation of the rotary arm 72 is not transmitted to the gear plate 73. However, when the rotating arm 72 rotates beyond a certain amount and the protrusion 732p of the gear plate 73 reaches the right end 722gd of the groove 722g, the protrusion 732p is urged in the rotation direction by the right end 722gd of the groove 722g. When this state is reached, the rotation of the rotary arm 72 is transmitted to the gear plate 73 via the right end 722gd of the groove 722g and the protrusion 732p, and the gear plate 73 also starts to rotate about the axis Y in the direction of the arrow d. .

  When the gear plate 73 rotates about the axis Y, power is transmitted to the gear 71g of the rotary table 71 meshing with the gear teeth 731g of the gear plate 73. Therefore, the rotary table rotates around the rotation center X in the direction of the arrow e.

  As shown in FIG. 11A, since the waste bag B1 containing a large amount of cutting waste W is placed on the rotary table 71, when the rotary table 71 rotates, the waste bag B1 also rotates. By this rotation, the waste bag B <b> 1 is twisted at the bound portion near the throttle mechanism 4. FIG. 11B shows a state where the rotary table 71 is rotated by opening the lower door 14 and the waste bag B1 is twisted. Here, the gear ratio of the sector gear 731 and the gear 71g of the rotary table 71 is determined so that the rotary table 71 rotates twice when the lower door 14 is opened to a position of about 100 degrees with respect to the front surface 10a of the housing 10. It has been. A blade 71h is provided on the upper surface 71e of the rotary table 71 (FIG. 8). The vane 71h prevents the waste bag B1 from sliding on the upper surface 71e of the turntable 71, so that the turntable 71 can efficiently rotate the waste bag B1.

<Aperture application operation>
Next, a description will be given of an operation for further reducing the cross-sectional area of the waste bag B1 in the horizontal plane by further restricting the waste bag B1 to which the to-be-bound portion is twisted. As shown in FIG. 11B, when the waste bag B1 is in a twisted state, the lower door 14 is in an opened state. Here, the user can give the squeeze bag B1 with the front-rear and left-right restrictors by holding the handle 55 of the binding / cutting mechanism 5 and pulling it up.

  FIG. 13 and FIG. 14 show how the aperture mechanism 4 moves by operating the binding / cutting mechanism 5. 13 shows the drawing mechanism 4 and the binding / cutting mechanism 5 from above, and FIG. 14 shows the drawing mechanism 4 and the binding / cutting mechanism 5 seen from the right. 13A and 14A, when the handle 55 of the bundling / cutting mechanism 5 is gripped and pulled in the direction of the arrow f, the bundling / cutting mechanism 5 rotates about the shafts 59c and 59d. . By this rotation, the sector gear 61 of the power transmission mechanism 6 that is integrally attached to the bundling / cutting mechanism 5 rotates in the clockwise direction (arrow f) in FIG.

  The rotational driving force of the sector gear 61 is transmitted within the power transmission mechanism 6 in the order of the sector gear 61, the driving gear 62, the toothed belt 67, the driven gear 64, the shaft 63, and the transmission gear 65 (FIG. 6B). As a driving force for the forward movement of the slide portion 40 of the aperture mechanism 4 via the rack gear 66 (FIG. 6B) provided on the lower surface 45 f of the lower aperture plate 45. More specifically, the sector gear 61 that rotates in the clockwise direction gives the drive gear 62 rotation in the counterclockwise direction, and the rotation of the drive gear 62 in the counterclockwise direction is via the toothed belt 67. It is transmitted to the driven gear 64 as the same counterclockwise rotation. The driven gear 64 that rotates in the counterclockwise direction rotates the transmission gear 65 in the counterclockwise direction via the shaft 62, and the transmission gear 65 moves the slide portion 40 forward via the rack gear 66 ( FIGS. 13B and 14C and FIGS. 14B and 14C.

  As the slide part 40 of the squeezing mechanism 4 moves forward, the waste bag B1 is squeezed in the front-rear direction and the left-right direction. First, in the front-rear direction, the front end 44a of the upper diaphragm plate 44 and the front end 45a of the lower diaphragm plate 45 that move to the front side press the waste bag B1 forward. Thereby, the width | variety of the front-back direction in the vicinity of the expansion mechanism 4 of the waste bag B1 is restrict | squeezed.

  In the left-right direction, the waste bag B <b> 1 is squeezed by the chuck 41 of the squeezing mechanism 4. When the slide portion 40 of the aperture mechanism 4 moves forward, the pin p13 of the chuck 41 fixed to the upper aperture plate 44 of the slide portion 40 and the pin p24 of the chuck 41 fixed to the base 46 are located. The distance in the front-rear direction increases, and accordingly, the pin p12 that connects the first long arm 411 and the first short arm 412 of the chuck 41, and the pin that connects the second long arm 413 and the second short arm 414. The distance in the left-right direction from p34 is reduced (FIG. 13B). The first long arm 411 is attached to the upper diaphragm plate 44 by a pin p13 on the tip 411t side from the pin p12, and the second long arm 413 is disposed on the tip 413t side from the pin p34 by the pin p13. 44 is attached. Therefore, when the slide part 40 moves in the forward direction and the pin p12 and the pin p34 approach each other in the left-right direction, the first long arm 411 and the second long arm 413 rotate around the pin p13, respectively, The distal end 411t of the long arm 411 and the distal end 413t of the second long arm 413 approach each other in the left-right direction. At this time, the waste bag B1 is squeezed in the left-right direction by the first long arm 411 and the second long arm 413 (FIG. 13C). The waste bag B1 squeezed in this way has a cross-sectional shape viewed from above elongated in the front-rear direction in the bound portion and its vicinity.

  FIG. 11C shows a state in which the sliding portion 40 of the throttle mechanism 4 is moved forward by pulling the binding / cutting mechanism 5 forward, and the waste bag B1 is provided with the throttle in the front-rear direction and the left-right direction.

<Bundling / cutting operation>
Next, an operation for binding / cutting the waste bag B1 to which twisting and drawing are applied will be described. As shown in FIG. 11 (c), in a state where the waste bag B1 is twisted and drawn, the slide portion 40 of the drawing mechanism 4 is moved forward, and the binding / cutting mechanism 5 further includes the left frame 53, The right frame 54 (FIG. 14C) is held horizontally. At this time, the left roller 56c and right roller 56d of the slide portion 50, the left guide groove 58cg and right guide groove 58dg of the rotating portion 57, the guide groove 42dg of the slide portion 40, and the guide groove 43cg constitute a moving mechanism. That is, the left guide groove 58cg of the rotating portion 57 of the bundling / cutting mechanism 5 and the guide groove 42dg of the left guide portion 42 of the aperture mechanism 4 are in contact with each other in a straight line in a horizontal plane, and a series of guide grooves 58cg, 42dg. The right guide groove 58dg of the rotating portion 57 of the bundling / cutting mechanism 5 and the guide groove 43cg of the right guide portion 43 of the aperture mechanism 4 are in contact with each other in a straight line in a horizontal plane, and a series of guide grooves 58 dg and 43 cg are formed. Therefore, when the slide part 50 of the bundling / cutting mechanism 5 is moved toward the rear side of the shredder 1 in this state, the left roller 56c and the right roller 56d of the slide part 50 are guided grooves 58cg, 42dg, guide grooves 58dg, 43 cg is rotated and the binders 51 and 51 and the cutter 52 of the slide part 50 are also moved toward the rear of the shredder 1. By this movement, the to-be-bundled portion of the waste bag B1 to which the torsion and the squeezing are applied and the spread in the horizontal plane is reduced is introduced into the introduction grooves 51m and 51m of the advancing binders 51 and 51. They are bundled at a place (first bundled portion, second bundled portion), and then cut by the cutter 52 in the middle of the two bundled portions (see FIG. 5). FIG. 11D shows a state where the waste bag B1 is bound and cut in this way.

<Trash bag discharge operation>
Finally, as shown in FIG. 11 (e), the bound waste bag B 1 is discharged from the lower door 14, and the waste bag B remaining inside the housing 10 is pulled down from the waste bag cartridge 33. Through the above operation, the waste bag B1 filled with the cutting waste W is discharged, and a new waste bag B2 that does not have the cutting waste W is disposed inside the housing 10. When the new waste bag B2 is filled with the cutting waste W again, the above operation is performed again to discharge the cutting waste W.

  The effects of the shredder 1 according to the present embodiment are summarized below.

  The shredder 1 according to this embodiment rotates the rotary table 71 of the rotation mechanism 7 and twists the waste bag B1 containing the cutting waste W. Therefore, the shredder 1 according to the present embodiment can narrow the bound portion of the waste bag B in advance, and can easily and reliably execute the binding of the waste bag B1 by the binder 51. Therefore, there is no need for a complicated and large mechanism for closing the bound portion from four directions, and the entire housing 10 and the shredder device can be made compact.

  The shredder 1 according to the present embodiment uses the movement of the lower door 14 that is always opened when the cutting waste W is discharged from the housing 10 as a driving force for rotating the rotary table 71 of the rotating mechanism 7. ing. Therefore, the shredder 1 of the present embodiment can rotate the rotary table 71 without requiring special labor and power, and can save power and reduce labor for discharging the cutting waste W.

  The shredder 1 according to the present embodiment is configured to be able to select whether or not to rotate the rotary table 71 by opening the lower door 14 by operating the handle 141 of the lower door 14, which is unnecessary. The rotation of the turntable 71 and unnecessary twisting to the waste bag B1 are prevented. Therefore, it is possible to select an operation according to the needs of the user, such as maintenance of the apparatus and disposal of the waste bag. In addition, blades 71h are attached to the rotary table 71 of the rotary mechanism 7, and the rotation of the rotary table 71 can be efficiently applied to the waste bag B.

  The shredder 1 which concerns on this embodiment gives the front-back direction and the left-right direction aperture | throttle using the aperture mechanism 4 with respect to the waste bag B1 which gave the twist. Therefore, the shredder 1 according to the present embodiment can further narrow the bound portion of the waste bag B1 even by the squeezing mechanism 4, and can more easily and reliably bind the waste bag B1 by the binding portion 51. .

  The shredder 1 according to the present embodiment accommodates the bundling / cutting mechanism 5 extending in the vertical direction, and the rotational movement given to the bundling / cutting mechanism 5 is the back-and-forth movement of the slide mechanism 40 of the aperture mechanism 4. It is configured to be transmitted. Therefore, in the shredder 1 according to the present embodiment, when the bundling / cutting mechanism 5 is lifted and rotated to perform the bundling / cutting operation, the shredder B is formed by the upper throttle plate 44 and the lower throttle plate 45 of the throttle mechanism 4. The aperture in the front-rear direction is applied. Therefore, the shredder 1 according to the present embodiment can efficiently use the space in the housing 10 to accommodate the binding / cutting mechanism 5 and make the housing 10 compact. At the same time, the waste bag B1 can be squeezed in the front-rear direction without requiring special labor or power, and the labor for discharging the cutting waste W can be reduced.

  The diaphragm mechanism 4 of the shredder 1 according to the present embodiment is configured such that the first long arm 411 and the second long arm 413 of the chuck 41 approach each other in the left-right direction in conjunction with the movement of the slide mechanism 40 moving forward. It is configured. Therefore, the shredder 1 according to the present embodiment can squeeze the waste bag B1 in the left-right direction without requiring special effort or power, and can reduce the trouble of discharging the cutting waste W.

  The shredder 1 according to the present embodiment uses a waste bag cartridge 33 in which a tube-shaped waste bag B is accommodated. Therefore, in the shredder 1 according to the present embodiment, after binding / cutting the waste bag B1 by the binding / cutting mechanism 5, only the lower end portion of the waste bag B hanging from the waste bag cartridge 33 is pulled down. Next, the waste bag B2 that accommodates the cutting waste W can be disposed inside the housing 10. Therefore, the trouble of discharging the cutting waste W can be reduced.

  Next, a method for manufacturing the shredder 1 according to the present embodiment will be described. When the shredder 1 according to the present embodiment is manufactured, the cutting mechanism 2, the drawing mechanism 4, the bundling / cutting mechanism 5, the power transmission mechanism 6, and the rotation mechanism 7 may be prepared and incorporated in the housing 10. The order of the assembling steps is not particularly limited. In the shredder 1 of the present embodiment, the aperture mechanism 4 and the rotation mechanism 7 are compact, and the binding / cutting mechanism 5 is arranged using the space in the housing 10 efficiently. Therefore, in manufacturing, it is also possible to use a casing that has been used in a conventional shredder that does not have a function of binding / cutting waste bags.

  In the shredder 1 of the present embodiment, it is possible to sufficiently suppress the spread of the waste bag B in the horizontal plane by using only the rotation mechanism 7, and the throttle mechanism 4 can be omitted. In this case, it is desirable to configure the rotary table 71 of the rotary mechanism 7 so that it can rotate more. An increase in the rotational speed of the turntable 71 can be realized by adjusting a gear ratio between the gear 71g and the sector gear 731, for example. By omitting the diaphragm mechanism 4, the housing 10 can be made more compact.

  In addition, in the rotation mechanism 7 of the shredder 1 of the present embodiment, the rotary table 71 may be electrically rotated by a motor. Moreover, it is good also as a structure rotated manually irrespective of the opening operation | movement of the lower door 14 using a pedal or a lever.

  In addition, the rotation mechanism 7 of the shredder 1 according to the present embodiment may have a structure in which the rotary table 71 is alternately moved clockwise and counterclockwise in conjunction with the opening of the lower door 14. Thereby, the waste bag B can be shaken by the opening of the lower door 14, and the cutting waste W in the waste bag B can be leveled.

  Note that the rotation mechanism 7 of the shredder 1 of this embodiment does not have to have the blades 71 h on the rotation table 71. Further, instead of the blades 71h, for example, a rubber layer may be formed on the upper surface 71e or a member having a large friction coefficient may be attached to the upper surface 71e so that the friction coefficient of the upper surface 71e of the turntable 71 is increased.

  It should be noted that the diaphragm mechanism 4 of the shredder 1 of the present embodiment has only one of the chuck 41, the upper diaphragm plate 44, and the lower diaphragm plate 45, and the others may be omitted. Thereby, a more compact shredder 1 can be obtained. Further, the upper diaphragm plate 44 and the lower diaphragm plate 45 do not necessarily need to be plate-like members, and may be arbitrary as long as the waste bag B is provided with a diaphragm in the front-rear direction. For example, the upper diaphragm plate 44 and the lower diaphragm plate 45 may be rod-shaped members passed between the left guide portion 42 and the right guide portion 43, respectively.

  In the shredder 1 of the present embodiment, the power transmission mechanism 6 may be omitted. In this case, the diaphragm mechanism 4 can be configured to be operated electrically by a motor. Moreover, it is good also as a structure which operates the aperture mechanism 4 manually using a pedal or a lever.

  In the shredder 1 of the present embodiment, the bundling / cutting mechanism 5 may not be accommodated in the housing 10. In this case, a holding hook or the like for holding the binding / cutting mechanism 5 may be provided on the outer surface of the housing 10 and the binding / cutting mechanism 5 may be held here.

  In the shredder 1 of this embodiment, the cartridge holding mechanism 3 may be omitted, and a waste bag holding frame such as a ring shape or a square shape that can hold the waste bag in an open state may be provided. In the shredder 1 of such a modified example, the user cuts the object to be cut in a state where the opening portion of the bag-like waste bag used in the conventional shredder is held by the waste bag holding frame. And when the cutting waste W is filled in the waste bag, the rotation mechanism 7 twists the waste bag, binds the waste bag with the binder 51, and packs the cutting waste W. After discarding the cutting waste W, a new bag-shaped waste bag is prepared and held by the waste bag holding frame. As is clear from the above description, the shredder 1 of this modification does not have the throttle mechanism 4, and does not require the bundling / cutting mechanism 5, and only needs to include one bundling device 51. With such a configuration, a more compact and inexpensive shredder 1 can be obtained.

  The shredder 1 of the present embodiment may have a bag-like waste bag or a waste bag holding frame that holds the waste bag cartridge 33 and is rotatable. In this case, the rotatable waste bag holding frame can be configured to be manually rotatable via a lever or the like with the upper door 13 opened. Alternatively, the opening operation of the lower door 14 may be transmitted as power for rotational movement of the waste bag holding frame using an arbitrary power transmission mechanism. By adopting such a configuration, it becomes possible to narrow the bound portion of the waste bag more narrowly, and it is possible to prepare and ensure further binding of the waste bag. The waste bag may be twisted only by the rotatable holding frame without having the rotary table 71, or the waste bag may be twisted by using the rotatable holding frame and the rotary table 71 together. Also good.

  In the shredder 1 of the present embodiment, the diaphragm mechanism 4, the bundling / cutting mechanism 5, and the rotation mechanism 7 may all be electrically driven. Thereby, the shredder 1 in which the waste of the cutting waste W can be more easily obtained can be obtained.

Second Embodiment
Next, a second embodiment of the present invention will be described. The second embodiment is different from the first embodiment in that the throttle mechanism 4 has a throttle bar 48 instead of the chuck 41. In the following, the same structures and elements as those of the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and description thereof is omitted.

  In the second embodiment, as shown in FIGS. 15A and 15B, the diaphragm mechanism 4 includes a left guide part 42, a right guide part 43, an upper diaphragm plate 44, a lower diaphragm plate 45, and a diaphragm rod 48. It is configured.

  The squeezing bar 48 is a device that gives the left and right squeezing to the waste bag B by the left squeezing bar 48c and the right squeezing bar 48d. The left aperture bar 48c includes a base 48c1 and a long bar 48c2 extending forward from the base 48c1. The right aperture bar 48d includes a base 48d1 and a long bar 48d2 extending forward from the base 48d1. The base 48c1 and the base 48d1 are each cylindrical, and a spiral gear is formed on the inner surface.

  The shaft 63 of the second embodiment has substantially the same structure as the shaft 63 of the first embodiment, but is different from the shaft 63 of the first embodiment in that it has spiral gears 63c and 63d on the left and right sides of the gear 65. Is different. The spiral gear 63c meshes with the spiral gear on the inner surface of the base 48c1 of the left throttle bar 48c, and the spiral gear 63d meshes with the spiral gear on the inner surface of the base 48d1 of the right throttle bar 48d.

  Therefore, in the second embodiment, when the slide portion 40 of the aperture mechanism 4 moves forward, the left aperture bar 48c receives power through the spiral gear 63c of the rotating shaft 63 and moves in the right direction. To do. The right aperture rod 48d receives power through the spiral gear 63d of the rotating shaft 63 and moves to the left. As a result, the bar 48c2 of the left throttle bar 48c and the bar 48d2 of the right throttle bar 48d approach each other in the left-right direction, and the waste bag B is squeezed in the left-right direction.

  According to the shredder 1 of the second embodiment, the iris mechanism 4 having a simpler structure is provided, and an inexpensive and compact shredder 1 can be obtained.

  In each of the above embodiments, the cutting mechanism 2 is not limited to the one having only the pair of roller cutters 21 and 22, and has an additional cutter that further cuts an object to be cut cut by the roller cutters 21 and 22. You can also. In this case, for example, after the cut object is cut linearly in the advancing direction by the roller cutters 21 and 22, the cut object can be further cut in a direction orthogonal to the advancing direction by an additional cutter.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. The case 100 of 3rd Embodiment consists of the main body 110 and the door 114 as shown in FIG. 16, and is provided with the rotation mechanism 7 of the structure and operation | movement similar to the housing | casing 10 of the shredder 1 of 1st Embodiment. Therefore, description of the elements of the rotation mechanism 7 described in the first embodiment is omitted.

  The case 100 of the present embodiment is configured to rotate the rotary table 71 through a power transmission mechanism by opening the door 114. Therefore, when taking out the placed object placed inside the main body 110, the placed object can be rotated without requiring any special labor or power.

  The case 100 of this embodiment is provided with a latch mechanism mainly composed of a rod 143 provided in the door 114 and a hole 721 h provided in the rotary arm 72, whereby the rotary table 71 is opened by the opening operation of the door 114.
