  However, only one or two emergency stop switches of the shredder are provided at a predetermined position with respect to the opening. Therefore, the emergency stop switch is operated from the side where the emergency stop switch is not provided. However, it was difficult to do.

  Therefore, the present invention relates to an improvement of the conventional shredder, and an object thereof is to provide a shredder capable of easily operating an emergency stop switch from any direction.

In order to solve the above problems, a shredder of the present invention is a shredder that shreds a shredded object inserted from an opening by a shredding mechanism, and a switch for changing the operating state of the shredding mechanism ; A detection unit that detects that the switch has been pressed, and the switch is integrally formed and disposed along the entire circumference of the opening so as to surround the opening. And at least one each on both sides in the width direction across the opening, and the operation state of the shredding mechanism is changed when any of the detection units detects that the switch is pressed. To do.

  In the shredder of the present invention, the switch is a switch for stopping the operation of the shredding mechanism.

  In the shredder of the present invention, the switch is a switch for switching the rotation of the shredding mechanism from normal rotation to reverse rotation.

  The shredder of the present invention is characterized in that the detection unit is arranged so as to be detected even when any part of the switch is pressed.

The shredder of the present invention is characterized in that an end portion on the opening side of the upper surface of the switch protrudes upward from other portions of the upper surface of the switch .

  In the shredder of the present invention, the switch is arranged to be separated from the opening.

  In the shredder of the present invention, the detection unit is a microswitch arranged to detect that the switch is pushed down.

  In the shredder of the present invention, the detection unit is a touch sensor as the switch.

  In the shredder of the present invention, the width of the switch is wider than the width of the opening.

  In the shredder of the present invention, the switch is colored differently from the opening and the housing of the shredder.

  According to the present invention, the switch is arranged so as to surround the opening continuously or intermittently. In other words, emergency stop switches are arranged in the vicinity of the opening and in all directions with respect to the opening. With this arrangement, the emergency stop switch can be easily operated from any direction, and the shredding can be stopped by operating any part of the switch.

  Moreover, since the switch is colored differently from the opening (upper surface member) and the shredder casing, it is possible to alert the user.

  Furthermore, by adopting a simple configuration in which the switch is assembled to the upper surface member via the elastic member, the number of parts necessary for the assembly of the switch can be reduced and can be easily assembled.

  Further, since the ridge is formed on the upper surface of the switch, the effect of preventing the ridge from slipping can be obtained.

  Hereinafter, a first embodiment according to the present invention will be described in detail with reference to the drawings. Here, FIG. 1 is a perspective view showing the configuration of the shredder 10, and FIG. 2 is a plan view showing the configuration of the shredder 10. As shown in FIG. 1 and FIG. 2, the shredder 10 according to the first embodiment has a shredded object (for example, paper, a compact disc, and the like) from an opening 31 (opening 35) disposed in the upper surface cover 12 of the housing 11. A credit card is inserted and shredded using a shredding mechanism (not shown) housed inside, and an emergency stop switch 50 is arranged along the entire circumference of the opening so as to surround the opening. ing. Fine pieces by the shredding mechanism are received in a dust box (not shown) housed in the housing 11. In addition, since a well-known thing is used for a shredding mechanism and a dust box, illustration and detailed description are abbreviate | omitted. As shown in FIGS. 1, 2, 9, 11, and 13, the top covers 12 and 312 are provided with a power switch 15 that switches supply of power to the shredder 10. 7 and 8 is provided with a recess 16 in which the power switch 15 is disposed.

  As shown in FIG. 3, the opening 35 has a longitudinal direction (FIG. 2) in the width direction (depth direction of the top cover 12) (vertical direction in FIG. 2) of the substantially rectangular top surface member 20 forming the top cover 12. The opening forming member 30 is fitted into a through-hole 21 provided so as to extend in the thickness direction (vertical direction in FIG. 3) (vertical direction) of the upper surface member 20. It is formed by joining. Here, FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2, wherein (a) shows a state in which the opening forming member 30 is fitted into the through hole 21 of the upper surface member 20, and (b) is It is a figure showing the state where a part of emergency stop switch 50 was pushed. As shown in FIG. 4, the opening forming member 30 is composed of two symmetrical members 30a and 30b formed by resin molding, and these are fitted into the through holes 21 so that the end surfaces 37a and 37b abut against each other. Thus, the opening 35 is formed. Here, FIG. 4 is an exploded perspective view showing the configuration of the opening forming member 30. As shown in FIGS. 3 and 4, the opening forming member 30 includes a linear portion 31 extending in a horizontal plane so as to form an opening when the corresponding end surfaces 37 a and 37 b are brought into contact with each other, and this line The vertical planar portion 32 that forms a conduction path that extends downward from the ridge portion 31 along the vertical direction (vertical direction in FIGS. 3 and 4), that is, toward the chopping mechanism, and the object to be chopped is drawn into the opening 31. An inclined portion (insertion guide) 33 that is inclined away from the center of the opening 31 as it goes upward is provided so as to form a guide shape. The opening 35 is configured by the opening formed by the linear portion 31 and the guiding shape formed by the inclined portion 33. In the present embodiment, the case where the inclined portion (insertion guide) 33 is provided is described, but the present invention is not necessarily limited to the case where the inclined portion (insertion guide) 33 is provided. .

  Thus, while the through hole 21 is provided in the upper surface member 20, the opening forming member 30 molded separately from the upper surface member 20 is fitted into the through hole 21 to be joined to the upper surface member 20 and the opening 35. Therefore, even when the width of the opening is narrowed and the path to the shredding mechanism is lengthened, the die can be easily removed, and the manufacturing cost can be reduced. In the present embodiment, the through hole 21 is formed in the upper surface member 20, and the opening forming member 30 is fitted and joined to the through hole 21. However, the upper surface member 20 is not provided with the through hole. The opening may be formed by combining and joining the upper surface member and the opening forming member.

  Further, since the inclined portion 33 also serves as a partition wall that separates the emergency stop switch 50 from the opening 31, the shredded object that the user intends to enter into the opening 31 contacts the emergency stop switch 50. By doing so, it is possible to prevent the emergency stop switch 50 from being activated, thereby preventing the emergency stop switch from malfunctioning.

  In addition, if the emergency stop switch 50 and the opening 31 can be separated from each other, the inclined portion 33 as the partition wall portion can be formed to extend upward at a position separated from the opening 31. In this case, the inclined portion 33 may be formed integrally with the upper surface member 20 or may be formed separately and fixed to the upper surface member 20.

  Moreover, it is preferable that the upper end of the inclined portion 33 as the partition wall is at the same height as the upper surface of the emergency stop switch 50 or at a position lower than the upper surface.

  Furthermore, depending on the specifications of the shredder 10, the inclined portion 33 as the partition wall is disposed only in a part between the opening 31 and the emergency stop switch 50 so as to separate the opening 31 and the emergency stop switch 50 from each other. You can also.

  The width W of the opening 31 and the depth of the conduction path 32 (FIG. 6) are preferably set from the viewpoint that nothing other than the shredded object enters.

  In the width direction of the upper surface member 20, two recesses 25 for receiving the detection switches (detection units) 60 are formed on both sides of the opening 31. The concave portion 25 has a shape in which the upper side is opened via a step portion 24 connected from the upper end of the inclined portion 33. In the center of the concave portion 25, a receiving portion 25a to which the lower surface of the detection switch 60 is bonded and fixed is projected upward. A wall portion 26 as a side wall forming the concave portion 25 extends outward (upward) from the housing 11 of the shredder 10 and is disposed so as to surround the detection switch 60. Thus, by surrounding the detection switch 60 with the wall portion 26, it is possible to prevent paper dust and dust from entering and accumulating inside the detection switch 60 and below the emergency stop switch 50. Further, by providing the stepped portion 24, the rigidity around the recessed portion 25 can be improved. Note that the configuration and arrangement of the wall portion can be arbitrarily set as long as foreign matter can be prevented from entering the periphery of the emergency stop switch 50. For example, the wall portion may be a flat plate, the upper portion may be bent toward the emergency stop switch 50, or may be constituted by a columnar member. Further, for example, the emergency stop switch 50 may be provided only on the side of the opening 31 where paper dust is likely to come out. Furthermore, even when surrounding the emergency stop switch 50, in consideration of the surrounding environment including the opening 31, it is possible to arrange a large wall portion in a direction in which a foreign object easily enters, and to arrange a small wall portion in other directions. .

  As shown in FIGS. 2 and 7, the emergency stop switch (switch) 50 is integrally formed in a rectangular shape in plan view by molding resin. Four ridges 53 are integrally formed on the upper surface of the longitudinal portion 51 so as to protrude upward and along the longitudinal direction. The ridge 53 has an anti-slip effect, and thus the emergency stop switch 50 can be reliably operated in an emergency. A columnar support member 54 is provided so as to extend downward from the lower surface of the longitudinal portion 51 of the emergency stop switch 50. Three support members 54 are arranged at equal intervals in the longitudinal direction in each of the two longitudinal portions 51. The end portion of the emergency stop switch 50 forms a switch side wall portion 55 extending downward, and the upper portion of the detection switch 60 is accommodated in a recess 57 formed by the switch side wall portion 55 and opened on the lower side. Here, FIG. 7 is an exploded perspective view showing configurations of the upper surface member 20 and the emergency stop switch 50. The number of ridges 53 can be any number and length according to the size of the emergency stop switch 50 and other specifications. It can also be provided in the width direction portion 52. Furthermore, the support members 54 can be arranged in any number according to the size of the emergency stop switch 50 and other specifications, and can be arranged at any intervals. The emergency stop switch 50 itself can be used as a touch sensor, and the detection switch 60 and the coil spring 70 can be omitted. In this case, it is preferable to adjust the detection level of the touch sensor so that the shredding mechanism is not stopped as long as the shredding object is touched.

  The emergency stop switch 50 is colored differently from the opening 31 (upper surface member 20) and the housing 11 of the shredder 10. For example, when the color of the upper surface member 20 and the housing 11 is white, the emergency stop switch 50 is colored orange or red. Thus, the user can be alerted by setting the color of the emergency stop switch 50 to a color different from that of the surrounding members.

  As shown in FIG. 3, in the state where the emergency stop switch 50 is assembled to the upper surface member 20, the switch side wall 55 extends toward the recess 25. As a result, the detection switch 60 is not only surrounded by the wall portion 26 as described above, but is also surrounded by the switch side wall portion 55. For this reason, it is possible to effectively prevent paper dust and dust from entering and accumulating below the detection switch 60 and the emergency stop switch 50. The switch side wall 55 may be provided so as to cover the outside of the recess 25. Moreover, you may provide the switch side wall part 55 only in the opening 31 side from which paper dust tends to come out, without providing in all the edge parts of the emergency stop switch 50, for example. Further, in the case of providing at all ends of the emergency stop switch 50, in consideration of the surrounding environment including the opening 31, a large switch side wall is disposed in a direction in which foreign matter easily enters, and the other direction is a small switch side wall. Parts can also be arranged.

  The detection switch 60 shown in FIG. 3 is a well-known micro switch, and detects when the top 63 fixed to the tip of the shaft 62 extending upward from the main body 61 is pushed into the main body 61. Output a signal. As shown in FIG. 7, the lower surface of the main body 61 is fixed to the upper end surface of the receiving portion 25 a of the concave portion 25, and the upper surface of the top portion 63 is bonded and fixed to the inner surface of the concave portion 57. On the other hand, a coil spring (elastic member) 70 is externally attached to the support member 54 of the emergency stop switch 50, and the upper end of the coil spring 70 is in contact with the inner surface of the emergency stop switch 50 and the lower end thereof is in contact with the upper surface member 20. Thus, the emergency stop switch 50 is fixed while being urged away from the upper surface member 20. At this time, the upper portion of the inclined portion 33 enters the rectangular through hole 58 in the center of the emergency stop switch 50, and the emergency stop switch 50 is disposed so as to surround the opening 31 in plan view.

  Thereby, it becomes possible to stop shredding by operating any part of the emergency stop switch. Further, the emergency stop switch can be easily operated from any direction. The number and arrangement of the detection switches 60 can be arbitrarily selected, but if there are one or more on both sides of the opening 31, the detection switch 60 can be detected regardless of which direction the emergency stop switch 50 is pressed. preferable. The detection switch 60 can be a switch or a sensor other than the micro switch if it can detect that the user has pressed the emergency stop switch 50. Furthermore, the simple configuration in which the emergency stop switch 50 is assembled to the upper surface member 20 via the detection switch 60 and the coil spring 70 can reduce the number of parts required for the assembly of the emergency stop switch 50. Can be assembled easily.

  The length and elastic force of the coil spring 70 are such that the top 63 of the detection switch 60 is not pushed into the main body 61 and the emergency stop switch 50 is pushed in a natural state where the user does not push the emergency stop switch 50 toward the top member 20. It is set so that the detection switch 60 does not detect that this has been done. Furthermore, it is preferable to set the elastic force of the coil spring 70 according to the detection specifications of the emergency stop switch 50, that is, how much force is applied to the emergency stop switch 50. Moreover, if it can urge | bias with respect to the emergency stop switch 50, elastic members (for example, leaf | plate spring, rubber | gum) other than the coil spring 70 can also be used.

  The four detection switches 60 are connected to a detection circuit (not shown) housed in the housing 11, and when any of the detection switches 60 detects the pressing of the emergency stop switch 50, a detection signal is sent to the detection circuit. . Upon receiving the detection signal, the detection circuit sends a drive stop signal to a drive source (not shown) of the shredding mechanism, so that the drive source immediately stops shredding operation regardless of the operating state of the shredding mechanism. To do. For example, as shown in FIG. 3B, even when a part of the emergency stop switch 50 is pushed by the force F and only the top 63 of one of the detection switches 60 is pushed into the main body 61 side, this detection is also performed. The detection circuit that has received the detection signal from the switch 60 sends a drive stop signal to the drive source of the shredding mechanism to immediately stop the shredding mechanism. In the above description, the operation of the shredding mechanism is stopped by pressing the emergency stop switch 50. However, the emergency stop switch 50 is a switch for changing the operating state of the shredding mechanism. Other operations may be performed. For example, it can also be configured as a switch that switches the rotation of the shredding mechanism from normal rotation to reverse rotation by pressing the emergency stop switch 50.

  Here, in the above-described embodiment, the vertical planar portion 32 of the opening forming member 30 inserted into the through hole 21 forms a conduction path toward the shredding mechanism. Instead, as shown in FIG. In addition, the leading end portion 121a of the through-hole 121 provided so as to extend in the longitudinal direction substantially at the center in the width direction of the upper surface member 20 and penetrate the upper surface member 20 in the thickness direction can also be formed as a conduction path. Here, FIG. 5 is a cross-sectional view corresponding to FIG. 3, wherein (a) shows a state in which the opening forming member 130 according to the modification of the first embodiment is fitted into the upper surface member 120, and (b) is It is a figure showing the state where a part of emergency stop switch 50 was pushed. In addition, the same code | symbol is attached | subjected to the same member as 1st Embodiment, and detailed description is abbreviate | omitted.

  In this modification, the opening forming member 130 is fitted into the through-hole 121 so that the tip abuts the inner surface of the inclined portion 121c extending from the base 121b having a large inner diameter of the through-hole 121 to the tip portion 121a having a small inner diameter. The opening forming member 130 is composed of two symmetrical members formed by resin molding, similar to the opening forming member 30. The opening forming member 130 is inserted into the through-hole 121 and the corresponding end faces are brought into contact with each other. Part 135 is configured. As shown in FIG. 5, the opening forming member 130 has a linear portion 131 extending in a horizontal plane so as to form an opening when corresponding end surfaces are brought into contact with each other, and a vertical direction from the linear portion 131. A vertical planar portion 132 that forms a part of the conduction path toward the shredding mechanism, and an inclined portion that expands toward the top so as to form a guide shape that invites the shredded object to the opening 131. 133 is provided. An opening 135 is formed by the opening formed by the linear portion 131 and the guiding shape formed by the inclined portion 133. The vertical planar portion 132 and the tip portion 121a communicate with each other to form a conduction path toward the shredding mechanism.

  In this way, the opening forming member 130 formed separately from the upper surface member 120 is fitted into the through hole 121 to form the opening 135, thereby opening the conductive path with only the upper surface member. Even if the width is narrowed and the path leading to the shredding mechanism is lengthened, die-cutting is easy, and the cost for manufacturing can be suppressed.

  The members 30a and 30b forming the opening forming member 30 may be asymmetrical as long as the opening 35 can be formed. Alternatively, the opening forming member 30 may be formed by bringing three or more members into contact with each other. Furthermore, you may comprise so that opening may be formed with an upper surface member and an opening formation member.

  Further, the opening forming member 30 and the opening forming member 130 described above are constituted by two symmetrical members, and the corresponding end surfaces are brought into contact with each other when fitted into the through hole 21 or the through hole 121. Alternatively, the opening forming member can be formed as a single member. This eliminates the need to abut the corresponding end face when fitted into the through hole 21 or the through hole 121 as in the opening forming member 30 or the opening forming member 130, so that the top member is fitted into the through hole. Can be easily performed, and the opening and the conduction path can be reliably formed.

  Furthermore, as shown in FIG. 6, the opening 235 can be formed without using the opening forming member. Here, FIG. 6 is a cross-sectional view corresponding to FIG. 3, in which (a) shows a configuration of an upper surface member 220 according to a further modification of the first embodiment, and (b) is a part of the emergency stop switch. It is a figure which shows the state by which was pressed. In addition, the same code | symbol is attached | subjected to the same member as 1st Embodiment, and detailed description is abbreviate | omitted.

  The opening 231 is integrally formed of resin as a part of the upper surface member 220 forming the upper surface cover 12 and penetrates through the center of the upper surface member 20 in the width direction. The opening 231 is connected to a conduction path 232 as a through hole toward the shredding mechanism on the lower side (lower side in FIG. 6). On the other hand, on the upper side (upper side in FIG. 6), the opening 231 is connected to an inclined portion 233 that expands upward so as to form a guide shape that invites the object to be shredded into the opening 231. An opening 235 is constituted by the portion 233. Thus, by forming the opening 235 without using the opening forming member, the work of fitting the opening forming member into the upper surface member becomes unnecessary, so that productivity can be improved.

  In the first embodiment, the shredder having one opening 31 is described. However, the present invention can be applied to a case where there are a plurality of openings. Further, the present invention can be applied to the case where the opening 31 is provided not on the upper surface of the shredder 10 but on another surface.

Next, a second embodiment will be described with reference to FIG.
In the first embodiment, the emergency stop switch 50 is formed by integral molding. However, the emergency stop switch can be divided into a plurality of parts as long as the opening 31 is surrounded. In the second embodiment, like the emergency stop switch 150 of the shredder 110 shown in FIG. 8, two U-shaped switches 151 having a U-shaped emergency stop switch 50 cut at substantially the center in the width direction, Divided into 152. In this case, the ridges 153, the detection switches 160, and the coil springs 170 corresponding to the ridges 53, the detection switches 60, and the coil springs 70 of the above-described embodiment are arranged in the same manner as the ridges 53, the detection switches 60, and the coil springs 70, respectively. . Moreover, it is preferable that at least one detection switch 160 is arranged for each divided switch. This is because an emergency stop is required regardless of which switch is pressed. Here, FIG. 8 is an exploded perspective view showing configurations of the emergency stop switch (switch) 150 and the upper surface member 20 according to the second embodiment.

  In this way, by enclosing the opening 31 intermittently with the emergency stop switch 150 or arranging the switches 151 and 152 so as to sandwich the opening 31, any part of the emergency stop switch is operated to perform shredding. In addition to being able to stop, the emergency stop switch can be operated from any direction.

  Next, a third embodiment of the present invention will be described. Here, FIG. 9 is a perspective view showing configurations of the emergency stop switch (switch) 250 and the top cover 12 of the shredder 210 according to the third embodiment, and FIG. 10 is an emergency stop switch of the shredder 210 according to the third embodiment. It is a side view which shows the structure of 250 and an upper surface cover. In the shredder 210 of the third embodiment, an emergency stop switch 250 is provided instead of the emergency stop switch 50 of the first embodiment. As shown in FIGS. 9 and 10, in the emergency stop switch 250, a substantially square-shaped end portion 259 on the side of the rectangular through hole 258 in which the opening 35 is inserted is formed from other parts of the emergency stop switch 250. Also protrudes upward. Four ridges 253 are integrally formed on the upper surface of the emergency stop switch 250 so as to protrude upward and along the longitudinal direction. The protruding amount of the end portion 259 can be arbitrarily determined. Thus, the emergency stop switch 250 can be easily pushed by projecting the end portion 259.

  Next, a fourth embodiment of the present invention will be described. In the shredder 310 according to the fourth embodiment, a shredding start switch 340 that detects that a shredding object has been inserted into the conduction path and starts shredding of the shredding mechanism is provided. In the shredder 310 shown in FIG. 11 and FIG. 12, no emergency stop switch is arranged to describe the shredding start switch 340 in detail. However, the shredding start switch 340 according to the fourth embodiment is the first shredder 310 described above. It can be applied to the third embodiment. For example, what is applied to the third embodiment is a shredder 410 according to a modification of the fourth embodiment shown in FIG. 13, and a shredding start switch 440 having the same configuration as the shredding start switch 340 is provided. Since the configuration and operation of the shredding start switch 440 are the same as those of the shredding start switch 340, detailed description thereof is omitted. Here, FIG. 11 is a perspective view showing a configuration of a shredder 310 according to the fourth embodiment. 12A and 12B are diagrams showing the configuration of the shredding operation start switch 340 according to the fourth embodiment, wherein FIG. 12A is a cross-sectional view taken along line XIIA-XIIA in FIG. 11, and FIG. 12B is a cross-sectional view taken along line XIIB in FIG. It is sectional drawing along the line -XIIB. FIG. 13 is a perspective view illustrating configurations of an emergency stop switch, a shredding operation start switch, and an upper surface cover of a shredder 410 according to a modification of the fourth embodiment.

  As shown in FIGS. 11 and 12, the shredder 310 according to the fourth embodiment inserts a shredded object through an opening 331 (opening 335) disposed on the upper surface cover 312 of the housing 311 and accommodates the shredder 310 inside. Shredding is performed using a shredding mechanism (not shown). As shown in FIG. 12, the opening 335 extends in the longitudinal direction substantially at the center in the width direction of the upper surface member 320 having a substantially rectangular shape in plan view forming the upper surface cover 312 and penetrates the upper surface member 320 in the thickness direction. It is formed by fitting the opening forming member 330 into the through-hole 321 provided in. The opening forming member 330 is formed by resin molding and extends in a horizontal plane so as to form an opening, and extends downward from the linear portion 331 along the vertical direction, that is, toward a shredding mechanism. A vertical planar portion 332 that forms a conduction path, and an inclined portion 333 that expands toward the top so as to form a guide shape that invites the shredded object to the opening 331 are provided. An opening 335 is formed by the opening formed by the linear portion 331 and the guiding shape formed by the inclined portion 333. The opening forming member 330 may be composed of two symmetrical members like the opening forming member 30 of the first embodiment, or may be composed of an integrated member.

  As shown in FIG. 12A, the opening forming member 330 is provided with a switch insertion portion 338 that is notched along the width direction at the center portion in the longitudinal direction. A distal end portion 342 a of an insertion detection member 342 that can swing around a shaft 341 is inserted into the insertion portion 338. A sensor 343 that detects the swing of the insertion detection member 342 is connected to the insertion detection member 342. The sensor 343 is connected to a driving source (not shown) of the shredding mechanism. When the sensor 343 detects that the insertion detection member 342 has swung, the sensor 343 sends a shredding start signal to the driving source of the shredding mechanism and receives this signal. The drive source starts the operation of the shredding mechanism. When the tip of the shredded object inserted into the vertical planar portion 332 comes into contact with the tip portion 342a of the insertion detection member 342, and the tip portion 342a is further pushed down, the insertion detection member 342 is Swings down to the center. As a result, when the sensor 343 detects the swing of the insertion detection member 342, a shredding start signal is sent to the driving source of the shredding mechanism, and the driving source that receives this starts the operation of the shredding mechanism.

  On the other hand, the shaft 341 also supports the end portion 344a of the lever member 344 so as to be swingable. The other end 344b of the lever member 344 extends to the outside from a through hole 328 penetrating the upper surface member 320 in the vertical direction at a notch 327 formed by notching the substantially longitudinal center of the upper surface member 320. . When the operator operates the end 344b, the lever member 344 swings about the shaft 341, and the sensor 343 that detects this swing sends a shredding start signal to the drive source of the shredding mechanism, The received drive source starts the operation of the shredding mechanism.

  When such a shredding start switch 340 is provided, the shredding mechanism is operated by inserting a shredding object or the shredding mechanism is operated by operating the shredding start switch 340. Is possible.

  Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.
