     SUMMARY OF INVENTION 
     Technical Problem 
     In the method of using the blanking die, it needs to prepare an exclusive blanking die for each processing, and it is not easy to change the process. This method requires costs such as a production cost and a safekeeping cost of the die, and setup time costs for attaching and detaching the blanking die to and from an automatic blanking apparatus and adjusting it. Therefore, there is a problem of a large cost. Especially, when a small amount of and many kinds of products are to be processed, the cost increases. And, it is difficult to change the process. 
     Also, in the techniques disclosed in Patent Literatures 1 and 2, one blade is used for the cutting processing, which leads naturally a limit in the speeding-up. 
     An object of the present disclosure is to provide an apparatus of processing a sheet, a method of processing a sheet, and a computer program, in which the process can be easily changed, and be carried out at high speed in low cost. 
     Solution to Problem 
     To achieve the above object, the sheet processing apparatus ( 1 ) according to the present disclosure includes: 
     a first processing section ( 1000 ) which forms a plurality of first processing lines (LX 1 , LX 2 ) extending in a first direction (an X axial direction) on a sheet ( 4200 ) as an object to be processed by selectively making a plurality of tools ( 10 ,  210 ) contact with and release from the sheet, and relatively moving the plurality of tools to the first direction with respect to the sheet, at a first position; 
     a second processing section ( 2000 ) which forms a plurality of second processing lines (LY 1 , LY 2 ), extending in a second direction (a Y axial direction) orthogonal to the first direction on the sheet ( 4200 ) by selectively making a plurality of tools contact with and release from the sheet and relatively moving the plurality of tools to the second direction with respect to the sheet, at a second position; 
     a third processing section ( 3000 ) which forms a third processing line (aslant line, curved line) on the sheet, by selectively making a tool ( 10 ) contact with and release from the sheet ( 4200 ), and relatively moving the sheet and the tool, at a third position; 
     and a conveyance mechanism which conveys the sheet among the first position, the second position, and the third position. 
     For example, the first processing section ( 1000 ) conveys the sheet to the first direction (the X axial direction) in a condition that positions of the plurality of tools ( 10 ,  210 ) are fixed, 
     wherein the second processing section ( 2000 ) moves the plurality of tools ( 10 ,  210 ) to the second direction (the Y axial direction) in a condition that a position of the sheet is fixed, 
     and wherein the third processing section ( 3000 ) moves the tool ( 10 ) to a two-dimensional direction in a condition that a position of the sheet is fixed. 
     For example, the first position to the third position are arranged on a straight line, 
     wherein the first processing section ( 1000 ) conveys the sheet to a direction parallel to the straight line while fixing the positions of the plurality of tools, 
     wherein the second processing section ( 2000 ) moves the tool to a direction approximately orthogonal to the straight line while fixing the position of the sheet, and 
     wherein the third processing section ( 3000 ) moves the tool to a direction orthogonal to the straight line and a direction parallel to the straight line while fixing the position of the sheet. 
     For example, the first processing section carries out first processing while conveying the sheet to the second position or the third position. 
     For example, the tool comprises: 
     a blade ( 10 ) which cuts the sheet; and 
     an angle control mechanism ( 120 ) which controls a direction of the blade, and 
     wherein the processing lines are cutting lines formed by the blade. 
     For example, the tool comprises a creasing member ( 210 ) which forms a crease line, and a direction adjustment mechanism which adjusts a direction of the creasing member pursuantly. 
     For example, a control mechanism which identifies first processing data to form the first processing lines, second processing data to form the second processing lines, and third processing data to form the third processing line, from processing data of the sheet, may be included. In this case, the first processing section forms the first processing lines based on the first processing data, the second processing section forms the second processing lines based on the second processing data, and the third processing section forms the third processing line based on the third processing data. 
     In order to achieve the above object, a method of processing a sheet includes: 
     a first processing step of forming a plurality of first processing lines extending in a first direction on a sheet as an object to be processed in parallel, at a first position, by selectively making a plurality of tools contact with the sheet and release the plurality of tools from the sheet and relatively moving a plurality of tools to the first direction with respect to the sheet; 
     a second processing step of forming a plurality of second processing lines extending in a second direction orthogonal to the first direction on the sheet at, a second position, by selectively making a plurality of tools contact with the sheet and release the plurality of tools from the sheet and relatively moving a plurality of tools to the second direction with respect to the sheet; 
     a third processing step of forming a third processing line on the sheet, at a third position, by selectively making a tool contact with the sheet and release the tool from the sheet and relatively moving the sheet and the tool; and 
     a conveyance step of conveying the sheet among the first position, the second position, and the third position. 
     In order to achieve the above object, a computer program according to the present disclosure makes a computer execute: a step of controlling a driving mechanism for a plurality of tools and conveyance mechanism for a sheet, to form a plurality of first processing lines extending in a first direction on a sheet as an object to be processed, at a first position, by selectively making a plurality of tools contact with the sheet and release the plurality of tools from the sheet and relatively moving the plurality of tools to the first direction with respect to the sheet; 
     a step of controlling a driving mechanism for a plurality of tools and the conveyance mechanism for the sheet to form the plurality of second processing lines extending in a second direction orthogonal to the first direction on the sheet, at a second position, by selectively making the plurality of tools contact with the sheet and release the plurality of tools from the sheet and relatively moving the plurality of tools to the second direction with respect to the sheet; and 
     a step of controlling a driving mechanism for a tool to form a third processing line on the sheet, at a third position, by selectively making the tool contact with the sheet and release the tool from the sheet and relatively moving the sheet and the tool. 
     Advantageous Effects of Invention 
     According to the present disclosure, the processing is possible without using an exclusive blanking die, and the processing shape can be optionally adjusted. And, the setup time can be made small. Also, the processing cost can be restrained. Moreover, since the processing is carried out while using a plurality of tools in parallel, the processing can be sped up.

     DESCRIPTION OF EMBODIMENTS 
     Embodiment 1 
     A sheet processing apparatus and a method of processing a sheet according to an embodiment of the present disclosure will be described below with reference to the drawings. 
     As shown  FIG. 1 , a sheet processing apparatus  1  according to this embodiment is an apparatus which carries out cutting processing and creasing processing to a sheet  4200  as an object to be processed, by using tools (a creasing member  210  shown in  FIG. 2  and a cutter blade  10  shown in  FIG. 3 ). The sheet processing apparatus  1  includes a first processing section  1000 , a second processing section  2000  and a third processing section  3000 . The first processing section  1000  to the third processing section  3000  are arranged on a straight line, and while conveying the sheet  4200  from the first processing section  1000  to the third processing section  3000 , the sheet processing apparatus  1  sequentially processes as a first processing step, a second processing step, and a third processing step. 
     In the following explanation, to facilitate understanding, XYZ coordinates are set as shown in  FIG. 1  and is referred to appropriately. The X axial direction is a conveyance direction of the sheet  4200 , the Y axial direction is a direction orthogonal to the conveyance direction of the sheet  4200  and is parallel to the surface of sheet  4200 , and the Z axial direction is a direction perpendicular to the surface of sheet  4200 . Note that when being merely referred to as the X axial direction, the Y axial direction, and the Z axial direction, the directions contain the + and − directions of X axis, the + and − directions of Y axis, and the + and − directions of Z axis. 
     The sheet conveyance mechanisms of the first processing section  1000  to the third processing section  3000  are formed to be flush, and form one carrying surface as a whole. A table  4100  on which the sheet  4200  has been located is conveyed on the carrying surface in a conveyance step. The conveyance mechanism for conveying the table  4100  may be adopting a known optional structure. For example, the conveyance mechanism includes a rack, which is formed in the sheet processing apparatus  1  to extend in the X axial direction, and a pinion formed in the table  4100 . The pinion and the rack are engaged with each other. As the pinion rotates, the table  4100  moves to the + and − directions of X axis. 
     The sheet  4200  is an object to be processed and is arranged at a predetermined location of the table  4100  in a predetermined direction. An example of the sheet  4200  includes a cardboard, a corrugated paper, a resinous film and the like. The shape, size, and material of sheet  4200  are not limited. The minute holes are opened in the surface of table  4100 , and the table  4100  has a suction mechanism in its inside. The sheet  4200  is absorbed on the surface of table  4100  by suction force. 
     In the first processing section  1000 , six creasing mechanisms  1110 - 1160  and six cutting mechanisms  1210 - 1260  are arranged. The creasing mechanisms  1110 - 1160  and the cutting mechanisms  1210 - 1260  process the sheet  4200  being conveyed at a first position where they are arranged. 
     The creasing mechanisms  1110 - 1160  push the creasing members against the sheet  4200 , to form crease lines (hereinafter, to be referred to as X crease lines) as first processing lines on the sheet  4200  extending in the X axial direction as the first direction. 
     The creasing mechanisms  1110 - 1160  are supported by a fixation frame  1100  extending in the Y axial direction. Each of the creasing mechanisms  1110 - 1160  has a moving mechanism, and is configured to be movable independently to the Y axial direction along the fixation frame  1100 . The moving mechanism comprises a rack-and-pinion mechanism, a linear moving mechanism by using a ball screw, a timing belt moving mechanism and the like. The power source of the moving mechanism includes a stepping motor, a servo motor and the like. 
     The detailed configuration of the creasing mechanisms  1110 - 1160  will be described with reference to  FIG. 2 . 
       FIG. 2  shows the configuration of the creasing mechanism  1110 . The creasing mechanisms  1120 - 1160  have the configuration like the creasing mechanism  1110 . 
     As shown in the figure, the creasing mechanism  1110  includes a frame  201 , a bracket  202 , a creasing member  210 , a roller holding member  223 , a guide member  221 , an up-down moving motor  220 , a slider  222 , a rail  222   a , a lateral moving motor  230 , a pinion  231 , a rack  232 , a slider  240   a  and a rail  240   b.    
     The creasing member  210  has a disk structure. The thickness of this disk becomes thin gradually in the outer edge section, and this disk has a shape of sharp edge. The central shaft  211  of the creasing member  210  is held rotatably by the roller holding member  223 , and the creasing member  210  is possible to rotate to the direction of R 1 . 
     The roller holding member  223  is held by a shaft  224  of the up-down moving motor  220  through the guide member  221 . The roller holding member  223  is rotatable around the rotation shaft  225  which is coaxial with the shaft  224 . Thus, the creasing member  210  changes direction of it freely, as a direction adjustment mechanism which adjusts the direction of the creasing member according to force received by the creasing member  210 . The up-down moving motor  220  has a ball screw mechanism. By rotations of the up-down moving motor  220 , the shaft  224  moves to the Z axial direction (the upper or lower direction). 
     The guide member  221  is fixed to the shaft  224  to extend above along the side surface of up-down moving motor  220 . The slider  222  is fixed on the upper end section of guide member  221 . The slider  222  is slidably attached to the rail  222   a  which is mounted on the side surface of up-down moving motor  220  to extend in the Z axial direction. 
     When the slider  222  is moved to the Z axial direction (the upper or lower direction) along the rail  222   a , the guide member  221  is moved to the Z axial direction, too. When the guide member  221  is moved to the Z axial direction, the creasing member  210  is moved to the Z axial direction, too. 
     The up-down moving motor  220  is fixed to the frame  201  through the bracket  202 . The frame  201  includes an arm section extending in the X axial direction. The lateral moving motor  230  is fixed on this arm section. The pinion  231  is fixed on a rotation shaft of the lateral moving motor  230 . The pinion  231  is fixed on the fixation frame  1100 , and engages with the rack  232  extending in the Y axial direction. The slider  240   a  is installed to the frame  201 . On the other hand, the rail  240   b  is fixed on the fixation frame  1100  extending in the Y axial direction. The slider  240   a  is slidably attached to the rail  240   b . With this structure, by the rotations of the motor  230 , the frame  201  and the creasing member  210  supported by the frame  201  slide to the Y axial direction. 
     Before starting the creasing processing, a control section (not shown) moves the frame  201  to the + or − direction of Y axis by driving the lateral moving motor  230  to rotate the pinion  231 , to arrange the creasing member  210  in the position where the sheet  4200  is subject to the creasing processing. The control section, when starting the creasing processing, drives the up-down moving motor  220  to make the shaft  224  stick out from the main unit of motor  220 , so that the creasing member  210  is pushed to the starting point of the creasing processing of the sheet  4200 . After that, the control section conveys the table  4100  to the + or − direction of X axis in the condition that the position of the creasing member  210  is fixed (while fixing the creasing member  210 ). The sheet  4200  as the object to be processed is moved to the X axial direction with conveyance of the table  4100 , the creasing member  210  rotates according to the movement of the sheet  4200 , to form a crease line on the sheet  4200 . 
     The quantity (the depth) by which the creasing member  210  is pushed into the sheet  4200  needs a fine adjustment depending on the thickness and material of the sheet  4200 . In response to a control signal supplied from outside, the control section can adjust the quantity by which the creasing member  210  is pushed into the sheet  4200  by controlling a rotation quantity of the up-down moving motor  220 . 
     The cutting mechanisms  1210 - 1260  shown  FIG. 1  are arranged to the fixation frame  1200  extending in the Y axial direction. Like the creasing mechanisms  1110 - 1160 , the cutting mechanisms  1210 - 1260  are moved respectively to the position of cutting processing to the Y axial direction along the fixation frame  1200  by the moving mechanism. 
     The detailed configuration of the cutting mechanisms  1210 - 1260  will be described with reference to  FIG. 3 . 
       FIG. 3  shows the configuration of the cutting mechanism  1210 . The cutting mechanisms  1220 - 1260  have the configuration like the cutting mechanism  1210 . 
     As shown in the figure, the cutting mechanism  1210  includes a cutter blade  10 , a cutter folder  30 , a cutter shaft  40 , a sleeve  50 , a pulley  51 , a detection board  52 , a sensor  53 , a housing  55 , an eccentric cam  60 , a compression spring  65 , a vibration motor  110 , an angle adjustment motor  120  as an angle adjustment mechanism, a pulley  121 , and a timing belt  122 . 
     The cutter blade  10  is detachably attached to the cutter folder  30 . The cutter folder  30  is fixed to the cutter shaft  40 . The cutter shaft  40  is held in the sleeve  50  to be able to move in a center axial direction thereof (the Z axial direction) only in a predetermined stroke. The sleeve  50  is rotatably held in the housing  55  around the central axis of the cutter shaft  40 . The pulley  51  is fixed on the sleeve  50  coaxially. The pulley  51  is connected by the timing belt  122  to the pulley  121  which is coaxially fixed to a rotation axis of the angle adjustment motor  120 . The detection board  52  is fixed on the pulley  51 , and the sensor  53  detects the detection board  52 . 
     The rotation of the angle adjustment motor  120  rotates the pulley  121 . The rotation of pulley  121  rotates the pulley  51  and the sleeve  50  fixed to the pulley  51  through the timing belt  122 . The rotation of the sleeve  50  rotates the cutter shaft  40  in the sleeve  50 , and the cutter blade  10  held by the cutter folder  30  around the Z axis. A rotation quantity of the cutter blade  10  can be measured by the sensor  53  detecting the detection board  52 . 
     The vibration motor  110  is fixed to the upper part of the housing  55 . The eccentric cam  60  is fixed to a rotation shaft of the vibration motor  110 . The eccentric cam  60  is arranged at the top of the cutter shaft  40 . The cutter shaft  40  is biased upwardly by a compression spring  65  so that its upper end abuts the eccentric cam  60 . 
     When the rotation of the vibration motor  110  rotates the eccentric cam  60 , the cutter shaft  40  abutting the eccentric cam  60  is moved to the axial direction of itself. Thus, the cutter blade  10  vibrates in the axial direction of the cutter shaft  40 . 
     The housing  55  is fixed to a base  75 . The slider  150   a  is fixed to the base  75 . The slider  150   a  extends in the Z axial direction and is slidably held by the rail  150   b  which is fixed on the frame  151 . The rack  80  is fixed on the base  75 , and extends in the Z axial direction. The pinion  70  engages with the rack  80 . The pinion  70  is driven by the up-down moving motor  130  fixed to the frame  151 . 
     When the rotation of up-down moving motor  130  rotates the pinion  70 , to move the rack  80  to the Z axial direction. The base  75  is moved to the Z axial direction with the movement of the rack  80  to move the cutter blade  10  held by the base  75  to the Z axial direction. 
     The slider  160   a  is fixed to the frame  151 . On the other hand, the rail  160   b  extending in the Y axial direction is fixed on the fixation frame  1200 . The slider  160   a  is slidably attached to the rail  160   b . Thus, the frame  151  is held by the fixation frame  1200  to be movable to the Y axial direction. The rack  100  is fixed on the fixation frame  1200 . The pinion  90  engaging with the rack  100  is connected to the rotation shaft of the lateral moving motor  140  fixed on the frame  151 . 
     The rotation of the lateral moving motor  140  rotates the pinion  90  to move the frame  151  to the Y axial direction along the fixation frame  1200 . 
     Before the cutting processing, the control section (not shown) drives the lateral moving motor  140  to move the frame  151  to the Y axial direction so as to move the cutter blade  10  to a position at which the sheet  4200  is cut. Next, the control section drives the angle adjustment motor  120  to make the direction of the cutter blade  10  matches to a direction of the cutting line to be formed. The control section drives the vibration motor  110  to give the cutter blade  10  a vibration in the Z axial direction. When starting the cutting processing, the control section drives the up-down moving motor  130  to move the cutter blade  10  to the position where the sheet  4200  is cut. After that, the control section moves the sheet  4200  to the X axial direction in the condition that the position of the cutter blade  10  is fixed, so that a cutting line is formed as the first processing line on the sheet  4200  as the object to be processed. 
     The second processing section  2000  shown in  FIG. 1  forms processing lines (hereinafter, to be referred to as Y processing lines) as second processing lines on the sheet  4200  as the object to be processed to extend in the Y axial direction as a second direction. In the second processing section  2000 , the sheet  4200  is processed in the condition of staying at a second position. 
     A couple of fixation frames  2300  and  2400  extending in the Y axial direction are arranged in the second processing section  2000 . 
     The moving frames  2100  and  2200  are arranged to be bridged between the fixation frames  2300  and  2400 . The moving frames  2100  and  2200  are movable respectively to the Y axial direction on the fixation frames  2300  and  2400  by the moving mechanisms  2170  and  2270 . 
     The moving frame  2100  includes six creasing members  2110 - 2160 . Each of the creasing members  2110 - 2160  has the configuration shown in  FIG. 2 . Each of the creasing members  2110 - 2160  pushes the creasing member  210  against the sheet  4200  or releases the creasing member  210  from the sheet  4200 , and moves to the X axial direction along the moving frame  2100 . When the moving frame  2100  moves to the Y axial direction under the condition of pushing the creasing member  210  against the sheet  4200 , a crease line is formed on the sheet  4200  as the second processing line to extend in the Y axial direction. 
     The moving frame  2200  includes six cutting members  2210 - 2260 . Each of the cutting members  2210 - 2260  has the configuration shown in  FIG. 3 , and makes the cutter blade  10  pierce the sheet  4200  or release from the sheet  4200 , and moves to the X axial direction along the moving frame  2200 . When the moving frame  2200  is moved to the Y axial direction, under the condition of the cutter blade  10  piercing the sheet  4200 , a cutting line is formed on the sheet  4200  to extend in the Y axial direction. 
     Note that a processing time can be more reduced, if during the movement of the table  4100  which absorbs the sheet  4200 , the mechanisms which process first the sheet  4200  (for example, the rotation roller mechanisms) at the second processing section  2000 , have been sent to the origin position of the other mechanisms (e.g. the cutter mechanisms). 
     The third processing section  3000  shown in  FIG. 1  is a processing section for forming aslant or curved cutting lines as a third processing lines to the sheet  4200  as the object to be processed. In the third processing section  3000 , the sheet  4200  is processed under the condition of the sheet  4200  stayed at a third position. 
     The rails  3210  are fixed to both sides of the third processing section  3000 . The rails  3210  extend in the X axial direction. 
     A moving frame  3100  is arranged to be bridged between the rails  3210 . The moving frame  3100  includes a driving mechanism  3220 , and is formed to be movable on the rail  3210 . 
     The moving frame  3100  includes two cutting members  3110 ,  3120 . 
     Each of the cutting members  3110  and  3120  has the configuration shown in  FIG. 3 , and drives the cutter blade  10  to pierce the sheet  4200  or release from the sheet  4200 , and to move to the Y axial direction along the moving frame  3100 . 
     Next, the inner configuration of the sheet processing apparatus  1  will be described. 
     The sheet processing apparatus  1  includes a control mechanism  400  to drive each of the above-mentioned motors. 
     As shown in  FIG. 4 , the control mechanism  400  includes a storage section  410 , a first stage driver  420 , a second stage driver  430 , a third stage driver  440 , a conveyance driver  450  and a controller  460 . 
     The storage section  410  stores CAD data which defines the cutting processing and the creasing processing. 
     The first stage driver  420  drives each motor in the first processing section  1000  according to a control of the controller  460 . The motors of the first processing section  1000  include the up-down moving motor  220  and the lateral moving motor  230  of each of the creasing mechanisms  1110 - 1160 , and the vibration motor  110 , the angle adjustment motor  120 , the up-down moving motor  130 , and the lateral moving motor  140  of each of the cutting mechanisms  1210 - 1260 . 
     The second stage driver  430  drives each motor of the second processing section  2000  according to the control of the controller  460 . The motors of the second processing section  2000  include motors which respectively move the moving frames  2100  and  2200  to the Y axial direction, the up-down moving motor  220  and the lateral moving motor  230  of each of the creasing mechanisms  2110 - 2160 , and the vibration motor  110 , the angle adjustment motor  120 , the up-down moving motor  130 , and the lateral moving motor  140  of each of the cutting mechanisms  2210 - 2260 . 
     The third stage driver  440  drives each motor of the third processing section  3000  according to the control of the controller  460 . The motors of the third processing section  3000  include a motor which moves the moving frame  3100  to the X axial direction, the vibration motor  110 , the angle adjustment motor  120 , the up-down moving motor  130 , and the lateral moving motor  140  of each of the cutting mechanisms  3110  and  3120 . 
     The conveyance driver  450  controls a motor of the conveyance mechanism to convey the table  4100 . 
     The controller  460  produces first processing data to third processing data and conveyance data to process the sheet in the first processing section  1000  to the third processing section  3000  and to control the conveyance mechanism, and sends control signals to the first stage driver  420  to the third stage driver  440 , which drive the motors arranged in each processing section, and the conveyance driver  450 . 
     More specifically describing, the controller  460  includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an input/output processor (input/output device) and the like, and is contained in a computer. 
     The ROM stores a control program for the CPU to execute. This control program is to make the CPU execute the operation to analyze CAD data stored in the storage section  410 , and to control each motor of the first processing section  1000  to the third processing section  3000 , and the conveyance mechanism based on the analysis result. The details of the control will be described later. 
     The RAM functions as a work memory of the CPU to store the developed CAD data, a position of the sheet  4200  as the object to be processed, positions of each creasing member  210  and cutter blade  10 , and the like. 
     By executing the program stored in the ROM, the CPU deploys in the RAM, the CAD data stored in the storage section  410 , analyzes the deployed CAD data, and classifies processing lines (cutting lines and creasing lines) into processing lines extending in the X axial direction as first processing lines (hereinafter, to be referred to as X processing lines), processing lines extending in the Y axial direction as second processing lines (hereinafter, to be referred to as Y processing lines), and curved or aslant processing lines as third processing lines. Next, the CPU synchronously controls the motors in the first processing section  1000  and the conveyance mechanism through the first stage driver  420  and the conveyance driver  450  based on the data of the X processing lines as the first processing data to form the X processing lines. 
     Then, the CPU conveys the table  4100  by the conveyance driver  450  based on the conveyance data, to convey the sheet  4200  to the second processing section  2000 . 
     Then, the CPU controls the motors of the second processing section  2000  by the second stage driver  430  based on data of the Y processing lines as the second processing data, to form the Y processing lines. 
     Then, the CPU conveys the table  4100  by the conveyance driver  450  based on the conveyance data, to convey the sheet  4200  to the third processing section  3000 . 
     Then, the CPU controls each motor of the third processing section  3000  by the third stage driver  440  based on the data of the curved or aslant processing lines as the third processing data, to form the curved or aslant processing lines. 
     Next, a method of processing a sheet by the sheet processing apparatus  1  having the above mentioned configuration will be described. 
     To facilitate understanding, as shown in  FIG. 5A , it will be described with reference to an example of forming the cutting processing lines and the creasing lines on the sheet  4200  so as to produce a development sheet  4300  of a box from the sheet  4200 . Note that in  FIG. 5A , the solid lines show the cutting lines, the broken lines show the creasing lines, the whole is equivalent to the development of the box. 
     Also, the U axis and the V axis are set to orthogonalize based on one corner of the sheet  4200  and are referred appropriately. Also, the sheet  4200  is set on the table  4100  such that the U axis is parallel to the X axis and the V axis is parallel to the Y axis. The controller  460  can get a position of each tool of the sheet processing apparatus  1  on the UV coordinates by a sensor detecting a position of sheet  4200  on the XYZ coordinates in the sheet processing apparatus  1 . 
     First, the CAD data is stored in the storage section  410  to define the process of the development sheet. 
     The controller  460  analyzes the CAD data to extract the X processing lines extending in the X axial direction as the first processing lines schematically shown in  FIG. 5B  and the Y processing lines extending in the Y axial direction as the second processing lines schematically shown in  FIG. 5C . The remaining processing lines are curved/aslant processing lines as the third processing lines shown in  FIG. 5D . 
     The controller  460  allocates the creasing mechanisms  1110 - 1160  and the cutting mechanisms  1210 - 1260  in the first processing section  1000  for forming of the creasing lines and the cutting lines shown in  FIG. 5B . In this case, it is supposed that the cutting mechanism  1260  is allocated for forming of a cutting line LX 1  and the creasing mechanism  1160  is allocated for forming of a crease line LX 2 . Also, the controller  460  decides a starting point and a terminal point of each processing line. 
     Next, the controller  460  allocates the creasing mechanisms  2110 - 2160  and the cutting mechanisms  2210 - 2260  in the second processing section  2000  for forming of the Y crease lines and the Y cutting lines shown in  FIG. 5C . In this case, it is supposed that the cutting mechanism  2260  is allocated for forming of the Y cutting line LY 1 , and the creasing mechanism  2160  is allocated for forming of the Y crease line LY 2 . Also, the controller  460  decides a starting point and a terminal point of each processing line. 
     In the same way, the controller  460  allocates a cutting member in the third processing section  3000  for each cutting line shown in  FIG. 5D . Also, the controller  460  decides a starting point and a terminal point of each processing line. 
     The controller  460  determines a position on the XYZ coordinates in the sheet processing apparatus  1  by a sensor for the sheet  4200 . The controller  460 , since grasping a position of each tool on the XYZ coordinates, can determine a position of each tool on the UV coordinates through the coordinate transformation. 
     Next, the sheet  4200  as the object to be processed is arranged on the table  4100 . The sheet  4200  is fixed on the table  4100  by a suction mechanism of the table  4100 . 
     The controller  460  moves each of the creasing mechanisms  1110 - 1160  along the fixation frame  1100  through the first stage driver  420  so as to be positioned on a forming position of a corresponding X crease line in the Y axial direction. In the same way, the controller  460  moves each of the cutting mechanisms  1210 - 1260  along the fixation frame  1200  through the first stage driver  420  to be positioned on a forming position of a corresponding X cutting line in the Y axial direction. In an example of  FIG. 5 , the creasing mechanism  1160  is moved to a position on an X crease line LX 2  in the Y axial direction, and the cutting mechanism  1260  is moved to a position of X cutting line LX 1  in the Y axial direction. 
     On the other hand, the controller  460  drives the conveyance mechanism through the conveyance driver  450 , to convey the table  4100  for the creasing mechanisms  1110 - 1160  and the cutting mechanisms  1210 - 1260 . 
     The controller  460  determines whether or not the start point of each X crease line on the sheet  4200  reached a position of the member  210  of the creasing mechanisms  1110 - 1160  allocated for an X crease line. When judging that it has reached the position, the controller  460  drives the motor  220  of each of the creasing mechanisms  1110 - 1160  to push the creasing member  210  against the sheet  4200 . A direction of the creasing member  210  becomes the X axial direction with conveyance of the sheet  4200 . 
     After that, the creasing member  210  pushes the sheet  4200 , and by conveyance of the sheet  4200  to the X axial direction, a crease line is formed to extend in the X axial direction. 
     The controller  460  determines whether or not a terminal point of each X crease line on the sheet  4200  has reached the position of the member  210  of each of the creasing mechanisms  1110 - 1160  allocated for the X crease line. When judging that it has reached the position, the controller  460  drives the motor  220  of each of the creasing mechanisms  1110 - 1160  to release the creasing member  210  from the sheet  4200 , and moves it to a non-processing position. Thus, the crease line is formed on the sheet  4200  to extend in the X axial direction from the start point to the terminal. 
     In the same way, the controller  460  determines whether or not a start point of each X cutting line on the sheet  4200  has reached a position of the cutter blade  10  in each of the cutting mechanisms  1210 - 1260  allocated for the X cutting line. When judging that it has reached the position, the controller  460  drives the up-down moving motor  130  of each of the cutting mechanisms  1210 - 1260  for the cutter blade  10  to pierce the sheet  4200 . Also, the controller  460  drives the angle adjustment motor  120  to direct the direction of the cutter blade  10  to the − direction of X axis. Moreover, the controller  460  drives the vibration motor  110  to vibrate the cutter blade  10  up and down. 
     After that, the cutter blade  10  cuts the sheet  4200  vibratingly, and the cutting line is formed on the sheet  4200  to extend in the X axial direction. 
     When judging that a terminal point of each X cutting line on the sheet  4200  has reached the position of the cutter blade  10  of each of the cutting mechanism  1210 - 1260  allocated for the X the cutting line, the controller  460  drives the up-down moving motor  130  in each of the cutting mechanisms  1210 - 1260  to release the cutter blade  10  from the sheet  4200 , and moves it to a non-processing position. Thus, the crease line is formed on the sheet  4200  to extend in the X axial direction from the start point to the terminal. Then, the controller  460  stops the vibration motor  110 . 
     In the example of  FIG. 5 , when a start point PX 1  of the cutting line LX 1  has reached a position of the cutter blade  10  of the cutting mechanism  1260 , the controller  460  drives the up-down moving motor  130  for the cutter blade  10  to pierce the sheet  4200 . Note that a direction of the cutter blade  10  is previously directed to the direction of the X axis. Thus, the sheet  4200  is cut by the cutter blade  10 . Thereafter, when a terminal point PX 2  of the cutting line LX 1  on the sheet  4200  has reached the position of the cutter blade  10  of the cutting mechanism  1260 , the controller  460  drives the up-down motor  230  to release the cutter blade  10  from the sheet  4200 . Thus, the cutting line LX 1  is formed on the sheet  4200  to extend in the X axial direction. 
     In the same way, when a start point PX 3  of the crease line LX 2  on the sheet  4200  has reached a position of the creasing member  210  of the creasing mechanism  1160 , the controller  460  drives the up-down moving motor  220  to push the creasing member  210  against the sheet  4200 . Thus, the crease line is formed on the sheet  4200  by the creasing member  210 . On the other hand, when a terminal point PX 4  of the crease line LX 2  on the sheet  4200  has reached the position of the creasing member  210  of the creasing mechanism  1160 , the controller  460  drives the up-down moving motor  220  to release the creasing member  210  from the sheet  4200 . Thus, the crease line LX 2  is formed on the sheet  4200  to extend in the X axial direction. 
     When it finishes conveying the table  4100  on the first processing section  1000 , it completes to form a vertical processing line on the sheet  4200 . 
     In this way, while conveying the sheet  4200  from the first processing section  1000  to the second processing section  2000 , the processing of the sheet  4200  completes. 
     Note that, when all of the crease lines and the cutting lines could not be formed by once conveyance of the table  4100 , the table  4100  is returned to a reference position on the first processing section  1000 , and while moving the table  4100  to the X axial direction, the remaining processing lines are formed. 
     Also, a process may be carried out when conveying the sheet  4200  to the − direction of the X axial. In this case, the controller  460  controls the angle adjustment motor  120  by the first stage driver  420  to direct the cutter blade  10  to the + direction of the X axis. Also, the creasing member  210  rotates according to the movement of the sheet  4200  to change the direction of it. 
     In this way, when the sheet  4200  (the table  4100 ) is moved to a predetermined position of the second processing section  2000 , it completes to carry out the processing of the X crease lines and the X cutting lines on the sheet  4200 . 
     Then, the controller  460  conveys the table  4100  to the reference position of the second processing section  2000 . 
     Then, the controller  460  controls the lateral moving motor  230  of each of the creasing mechanisms  2110 - 2160  through the second stage driver  430  to move each creasing member  210  to a position on the X coordinate of a Y crease line for which the creasing member  210  is allocated. In the same way, the controller  460  drives the lateral moving motor  140  by the second stage driver  430  to move each cutter blade  10  to a position on an X coordinate of a corresponding Y cutting line. 
     Next, the controller  460  drives the moving mechanism  2170  by the second stage driver  430  in the condition of fixing the table  4100 , to move the moving frame  2100  to the − direction of Y axis along the fixation frame  2300 . 
     When judging that each creasing member  210  has reached a start point of the corresponding Y crease line, the controller  460  drives the motor  220  of each of the creasing mechanism  2110 - 2160  to push the creasing member  210  against the sheet  4200 . After that, in the condition of pushing the creasing member  210  against the sheet  4200 , the moving frame  2100  is moved to the − direction of Y axis to form the crease line to extend the Y axial direction. When the creasing member  210  has reached a terminal point of a lateral crease line which is being formed, the controller  460  drives the up-down moving motor  220  to release the creasing member  210  from the sheet  4200 . Thus, the crease line is formed on the sheet  4200  to extend in the Y axial direction from the start point to the terminal. 
     When finishing the formation of crease lines, the controller  460  returns the moving frame  2100  to a home position. 
     Then, the controller  460  drives the moving mechanism  2270  by the second stage driver  430  in the condition of fixing the table  4100  to move the moving frame  2200  to the + direction of the Y axis along the fixation frames  2300  and  2400 . Also, the controller  460  drives the angle adjustment motor  120  of each of the cutting mechanisms  2210 - 2260  to direct the cutter blade  10  to the + direction of the Y axis. 
     When judging that each creasing member  210  has reached a start point of a corresponding Y crease line, the controller  460  drives the up-down moving motor  130  of each of the cutting mechanisms  2210 - 2260  for the cutter blade  10  to pierce the sheet  4200 . Also, it drives the vibration motor  110  to vibrate the cutter blade  10  up and down. 
     After that, in the condition for the cutter blade  10  to pierce the sheet  4200  and move up and down, the moving frame  2200  moves to the + direction of Y axis to form a cutting line to extend in the Y axial direction. When the cutter blade  10  has reached a terminal point of the cutting line, the controller  460  drives the up-down moving motor  130  to release the cutter blade  10  from the sheet  4200 . Also, it stops the vibration motor  110 . Thus, the cutting line is formed on the sheet  4200  to extend in the Y axial direction from the start point to the terminal. 
     The controller  460  returns the moving frame  2200  to a home position, when finished the formation of cutting lines. 
     Referring to the example of  FIG. 5 , when the creasing member  210  of the creasing mechanism  2160  has reached a start point PY 3  of the creasing line LY 2  through the movement of the moving frame  2100 , the controller  460  pushes the creasing member  210  against the sheet  4200 . When the creasing member  210  of the creasing mechanism  2160  has reached a terminal point PY 4  of the creasing line LY 2 , the controller  460  releases the creasing member  210  from the sheet  4200 . Thus, the crease line LY 2  is formed. 
     When completing the formation of the crease lines, the controller  460  moves the moving frame  2200  to the + direction of Y axis. When the cutter blade  10  directing to the + direction of Y axis, of the cutting mechanism  2260  has reached the start point PY 1  of the cutting line LY 1 , the controller  460  controls the cutter blade  10  to pierce the sheet  4200 . When the cutter blade  10  of the cutting mechanism  2260  has reached the terminal point PY 2  of the cutting line LY 1 , the controller  460  releases the cutter blade  10  from the sheet  4200 . Thus, the cutting line LY 1  is formed. 
     When the formation of all of the Y crease lines and the Y cutting lines completes, the table  4100  is moved to the reference position of the third processing section  3000  in the condition of fixing the sheet  4200 . 
     The controller  460  carries out the cutting processing of the aslant cutting lines and the curved cutting lines on the sheet  4200  in the third processing section  3000 . Specifically, the controller  460  drives the moving mechanism  3220  by the third stage driver  440  to move the moving frame  3100  to the X axial direction and to move the cutting mechanisms  3110  and  3120 , which are synchronized with each other, along the moving frame  3100 . Moreover, the controller  460  drives the angle adjustment motor  120  to control the direction of the cutter blade  10  so as to match the inclination of the cutter blade  10  at a current position on the cutting line to be formed. 
     Moreover, the controller  460  pushes down the cutter blade  10  on a start point of the cutting line by the third stage driver  440 , to pierce the sheet  4200 , and draws up the cutter blade  10  on a terminal point to release it from the sheet  4200 . Also, during the cutting, the cutter blade  10  is vibrated. Moreover, during the cutting, the controller  460  drives the angle adjustment motor  120  to control the direction of the cutter blade  10  so as to match the direction of the cutter blade  10  with an inclination at a current position of the forming the cutting line. 
     In this way, through the operation of moving the sheet  4200  relatively to a two-dimensional direction of X and Y, the controller  460  forms the aslant cutting lines and the curved cutting lines. 
     In the example shown in  FIG. 5 , the cutting mechanism  3110  is allocated for the curved cutting lines L 11 , L 12 , L 15 , and L 16  and the aslant cutting lines L 13  and L 14 , and the cutting mechanism  3120  is allocated for the curved cutting lines L 21 , L 22 , L 23 , and L 24 . Next, the controller  460  moves the cutting mechanisms  3120  and  3110  along the moving frame  3100  while moving the moving frame  3100  to the X axial direction, adjusts the direction of the cutter blade  10 , and forms each cutting line by controlling an up and down operation of the cutter blade  10   
     Note that when a process finishes, the sheet  4200  is transferred to the device on the next stage (not shown), and the table  4100  is returned to the home position shown in  FIG. 1 . Alternatively, after the process has finished, the table  4100  is returned to the home position shown in  FIG. 1 , and the processed sheet  4200  is received by the other apparatus. 
     In this way, the sheet processing apparatus  1  of the present embodiment classifies processing lines into processing lines extending in the X axial direction, processing lines extending in the Y axial direction, and the other processing lines, and the processing lines are processed in parallel by a plurality of processing mechanisms. Therefore, the sheet  4200  can be processed at high speed. 
     Note that in this embodiment, only the processing lines extending in the X axial direction are processed at the first processing section  1000 . But, the present disclosure is not limited to this, and aslant processing lines and/or curved processing lines might be formed if an angle between the X axial direction and the processing line is within a predetermined angle, e.g. about 25 degrees or less. For example, the aslant or curved crease lines may be formed, by moving the creasing mechanisms  1110 - 1160  to the Y axial direction while moving the table  4100  to the X axial direction. In the same way, the aslant or curved cutting lines may be formed, by moving the cutting mechanisms  1210 - 1260  to the Y axial direction while moving the table  4100  to the X axial direction. In this case, it is desirable to control a rotation angle of the cutter blade  10  in synchronization (harmonious) with the movement of the cutter mechanisms  1210 - 1260 . 
     Also, in this embodiment, only the processing lines extending in the Y axial direction are processed in the second processing section  2000 . But, the present disclosure is not limited to this, and the aslant processing lines and/or the curved processing lines might be formed if an angle between the Y axial direction and the processing line is within a predetermined angle, e.g. about 25 degrees or less. For example, the aslant or curved crease lines may be formed, by moving each of the creasing mechanisms  2110 - 2160  to the Y axial direction while moving the moving frame  2100  to the Y axial direction. In the same way, the aslant or curved cutting lines may be formed, by moving the cutting mechanisms  2210 - 2260  to the X axial direction while moving the moving frame  2200  to the X axial direction. In this case, it is desirable to control the rotation angle of the cutter blade  10  in synchronization (harmonious) with the movement of the cutter mechanisms  2210 - 2260  to the X axial direction. 
     In this embodiment, crease processing is not carried out at the third processing section  3000 , but it is possible to arrange the creasing mechanism. In this case, a frame is arranged to move on the rail  3210  to the X axial direction, and the creasing mechanism moving to the Y axial direction is arranged at this frame. 
     A sequence is optional in which the first processing section  1000  to the third processing section  3000  are arranged. For example, the sequence may be in the order from the third processing  3000  to the first processing section  1000 . 
     Also, the sheet  4200  is conveyed in the condition of fixing tools (cutter blade  10 , the creasing member  210 ) in the first processing section  1000 , but like second processing section  2000 , the tools may be moved to the X axial direction in the condition of fixing the sheet  4200 . 
     Embodiment 2 
     In embodiment 1, the sheet processing apparatus  1  has been described in which the sheet  4200  is processed in different places such as the first processing section  1000 , the second processing section  2000 , and the third processing section  3000 . The present disclosure is not limited to this. In the identical place, it is possible to form the X processing lines, the Y processing lines, the aslant processing lines, and the curved processing lines. 
     In this case, for example, it is possible to achieve by using only the configuration of the second processing section  2000  in embodiment 1. 
     In this case, the sheet  4200  to be processed as is fixed on the table  4100  which is fixed on the second processing section  2000 . 
     First, the X processing lines (or Y processing lines) are formed. 
     Next, the table  4100  is rotated by 90 degrees, or the sheet  4200  as the object to be processed is rotated by 90 degrees. 
     Next, the Y processing lines (or X processing lines) are formed. 
     Next, the aslant processing lines and the curved processing lines are formed while one or two of the creasing mechanisms and/or the cutting mechanisms are moved to the X axial direction and the Y axial direction. In this way, it completes to process the sheet  4200  as the object to be processed. 
     Modified Embodiments 
     In embodiment 1 and embodiment 2 examples in which the cut sheet  4200  is processed are shown, but a continuous paper may be processed. In case of processing the continuous paper, the X processing lines are formed in the first processing section  1000  while the continuous paper is conveyed; after stopping the conveyance, the Y processing lines are formed in the second processing section  2000 ; moreover, after the conveyance, the aslant/curved processing lines are formed in the third processing section  3000 . 
     In case of processing the continuous paper, in configuration of embodiment 1, the X processing lines are formed in the first processing section  1000  while the continuous paper is conveyed; after stopping the conveyance, the Y processing lines are formed in the second processing section  2000 ; moreover, after the conveyance, the aslant/curved processing lines are formed in the third processing section  3000 . 
     Also, in the above mentioned embodiments, the sheet  4200  is fixed on the table  4100  by absorbing. The technique of fixing the sheet  4200  on the table  4100  is optional. For example, it is possible to adopt techniques of using an adhesion material to fix the sheet  4200  as the object to be processed on the table  4100  or fastening an edge of the sheet  4200  as the object to be processed with a clip formed on the table  4100  to fix the sheet  4200 , and the like. 
     In the above mentioned embodiments, the controller  460  extracts data of processing lines in the X axial direction as first processing data, data of processing lines in the Y axial direction as second processing data, and data of other processing lines as third processing data from CAD data. The present disclosure not being limited to this, and data of previously classified processing lines may be supplied to the controller  460  from outside.
