CROSS-REFERENCE TO RELATED APPLICATIONS 
     This U.S. National Stage Application claims priority under 35 U.S.C. §119(a) to Japanese Patent Application No. 2009-272686, filed in Japan on Nov. 30, 2009. The entire disclosure of Japanese Patent Application No. 2009-272686 is hereby incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to a folding system for a fabric product. 
     BACKGROUND ART 
     A variety of “folding devices for automatically folding a fabric product such as a shirt” have been proposed so far. 
     Depending on folding methods, the folding devices are roughly classified into slide type folding devices (see Japan Laid-open Patent Application Publication Nos. JP-A-H08-215500, JP-A-H08-215499, JP-A-H08-215498, JP-A-H08-215497, JP-A-2008-18100, JP-A-2000-202200 and JP-A-H05-294552), a flip-up-to-the-bottom type folding device (see Japan Laid-open Patent Application Publication Nos. JP-A-H06-304399 and JP-A-H10-218485), a flip-up-to-the-top type folding device (see Japan Laid-open Patent Application Publication Nos. JP-A-H07-61703, JP-A-2008-264316, JP-A-2003-532451, JP-A-2003-181200 and JP-A-2002-119800) and a rotary type folding device (see PCT International Application Publication No. WO2008/032826). 
     The folding devices as described above are mutually provided with a platen for putting a fabric product thereon. Every time the fabric product size is changed, the platen width is required to be suitably adjusted to the changed fabric product size. For example, the following methods are required for implementing the above. Every time the fabric product size is changed, a platen is replaced with another one with a width suitable for the fabric product size. Alternatively, the platen width is adjusted by means of a width adjusting mechanism as described in a brochure of International Patent Application Publication No. WO2008/032826 and etc. The latter method is herein preferable in consideration of a workload imposed on a worker. 
     Now, there exist a variety of fabric products for a variety of age groups (e.g., clothing of a grandfather, a grandmother, a father, a mother, a child and etc.) at home. Therefore, frequent width adjustment is required for the platen when the folding device as described above is installed in a home. A workload imposed on a worker is accordingly increased. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to reduce worker&#39;s workload required for adjusting the platen width in a folding system for a fabric product. 
     A folding system for a fabric product according to a first aspect of the present invention includes an information obtaining device, a folding device and a width controlling device. The information obtaining device is configured to obtain first information held by the fabric product. It should be noted that the term “first information” may herein refer to identification information (including image information, identification number information, etc.), or alternatively, “information of the width directional length of a platen member”. When the first information is the identification information, “information of the width directional length of a platen member” is required to be derived from the identification information. Further, the first information may be obtained from an information medium fixed to the fabric product. Examples of the information medium herein include a RFID tag, a barcode (e.g., one-dimensional barcode, two-dimensional barcode, further, a barcode made of fluorescent paint), fluorescent paint (forming information, for instance, by means of emission wavelength when being irradiated by black light), a metal piece (forming information depending on metal elements contained therein) and a magnetic recording medium. Alternatively, the first information may be data of the shape, the pattern, etc. of the fabric product (corresponding to the identification information in this case), in other words, imaging data (note the information obtaining device is herein an imaging device, i.e., a camera). The folding device includes a platen member, a width adjusting mechanism and a folding mechanism. It should be noted that examples of the folding mechanism include a rotary type folding mechanism as described in the brochure of PCT International Application Publication No. WO2008/032826, a flip-up-to-the-bottom type folding mechanism as described in Japan Laid-open Patent Application Publication Nos.

It should be noted in the present exemplary embodiment that the first nuts are configured to be slid and moved in opposite directions due to the structure that the first nuts are respectively screwed onto the right-handed thread ball screw portion and the left-handed thread ball screw portion of the first ball screw  531 . In other words, the first nuts are configured to be slid and moved closer to or away from each other. Further, the platen plate attachment member serves to fix the platen plates  501  to the first nuts. Yet further, the platen plate attachment member includes a rail engaging portion (not illustrated in the figures) on the back face thereof. The rail engaging portion is meshed with the rail portion of the first rail member. The first ball screw driving motor  532  is coupled to an end of the first ball screw  531  while the shaft thereof is arranged along the axis of the first ball screw  531 . 
     A pair of the folding plate sliding mechanisms  540  is disposed correspondingly to the dual nested shaft rotary mechanisms  520  in the right-and-left direction. As illustrated in  FIGS. 4 to 6 , the folding plate sliding mechanisms  540  mainly include the third ball screws  541   a  and  541   b , third nuts (not illustrated in the figures), third rail members  543 , third ball screw driving motors  545 , 31 st  pulleys  546 , 32 nd  pulleys  547  and third pulley belts  548 . Further, in the following explanation, the third ball screws with reference numerals of  541   a  and  541   b  may be respectively referred to as “a 31 st  ball screw” and “a 32 nd  ball screw”. As illustrated in  FIGS. 4 to 6 , two third ball screws  541   a  and  541   b  are disposed in roughly parallel to the first ball screw  531 . The third nuts are screwed onto two third ball screws  541   a  and  541   b , respectively. The dual nested shaft rotary mechanisms  520  are attached to the third nuts, respectively. Each 31 st  pulley  546  is fitted onto the tip of each third ball screw driving motor  545 . Each 32 nd  pulley  547  is fitted onto the base end of each third ball screw  541   a / 541   b . Each third pulley belt  548  is stretched over each 31 st  pulley  546  and each 32 nd  pulley  547 . Each third pulley belt  548  serves to transfer rotary power of each third ball screw driving motor  545  to each third ball screw  541   a / 541   b  through each 31 st  pulley  546  and each 32 nd  pulley  547  in order to rotate each third ball screw  541   a / 541   b . Each third ball screw driving motor  545  is forwardly and reversely rotatable. 
     (6-3) Transporting Mechanism 
     As illustrated in  FIGS. 4 to 6 , the transporting mechanism  600  mainly includes a pull-out plate  601 , a pull-out plate up-and-down transporting mechanism  610 , a pull-out plate rotary mechanism  620  and a pull-out plate back-and-forth transporting mechanism  630 . Elements of the transporting mechanism  600  will be hereinafter respectively explained in detail. 
     The pull-out plate  601  is a roughly rectangular plate member. It should be noted that the pull-out plate  601  includes two protrusions  603  and a rotary bar  602  as illustrated in  FIG. 6 . The protrusions  603  are backwardly extended, while the rotary bar  602  is fixed to the protrusions  603 . Further, a 21 st  pulley (not illustrated in the figure) is attached to the rotary bar  602 . 
     As illustrated in  FIGS. 4 to 6 , the pull-out plate up-and-down transporting mechanism  610  mainly includes a fourth ball screw  612 , a fourth ball screw driving motor  611 , a fourth nut  614 , an attachment plate  613 , an 11 th  pulley  615 , a 12 th  pulley belt  616  and a 12 th  pulley  617 . As illustrated in  FIGS. 4 to 6 , the fourth ball screw  612  is disposed while the axis thereof is arranged along the vertical direction Dv. The fourth nut  614  is screwed onto the fourth ball screw  612 . The fourth nut  614  is configured to be moved along the axial direction of the fourth ball screw  612  in conjunction with driving of the fourth ball screw driving motor  611 . The fourth nut  614  is fixed to the attachment plate  613 . Further, the attachment plate  613  includes rail portions  613   a  and  613   b  on the both ends thereof. It should be noted that the rail portions  613   a  and  613   b  are fitted onto the second pillar members  451  of the rear frame  450 . Therefore, the attachment plate  613  is configured to be moved up and down along the second pillar members  451  when the fourth nut  614  is moved up and down along the fourth ball screw  612 . Further, the pull-out plate  601  is attached to the front face of the attachment plate  613  through the pull-out plate rotary mechanism  620 . As illustrated in  FIGS. 4 to 6 , the 11 th  pulley  615  is attached to the shaft of the fourth ball screw driving motor  611 . As illustrated in  FIG. 4 , the 12 th  pulley  617  is attached to the bottom end of the fourth ball screw  612 . The 12 th  pulley belt  616  is stretched over the 11 th  pulley  615  and the 12 th  pulley  617 . In other words, in conjunction with driving of the fourth ball screw driving motor  611 , rotational power of the fourth ball screw driving motor  611  is transferred to the fourth ball screw  612  through the 11 th  pulley  615 , the 12 th  pulley belt  616  and the 12 th  pulley  617 . As a result, the fourth ball screw  612  is rotated about the axis thereof. The attachment plate  613  is consequently moved up and down along the second pillar members  451 . 
     As illustrated in  FIG. 6 , the pull-out plate rotary mechanism  620  mainly includes rotary bar support bodies  622   a  and  622   b , a 22 nd  pulley  623 , a 22 nd  pulley belt  624  and a rotary bar driving motor  621 . The rotary bar support bodies  622   a  and  622   b  support the rotary bar  602  disposed rearwards of the pull-out plate  601  for allowing it to rotate. The 22 nd  pulley  623  is attached to the shaft of the rotary bar driving motor  621 . The 22 nd  pulley belt  624  is stretched over the 22 nd  pulley  623  and the 20 pulley attached to the rotary bar  602 . In short, in conjunction with driving of the rotary bar driving motor  621 , rotational power of the rotary bar driving motor  621  is transferred to the rotary bar  602  through the 22 nd  pulley  623 , the 22 nd  pulley belt  624  and the 21 st  pulley. As a result, the pull-out plate  601  is upwardly pivoted and lifted up. In reverse driving of the rotary bar driving motor  621 , by contrast, rotary power of the rotary bar driving motor  621  is transferred to the rotary bar  602  through the 22 nd  pulley  623 , the 22 nd  pulley belt  624  and the 20 pulley. As a result, the pull-out plate  601  is downwardly pivoted and tilted downwards. 
     The pull-out plate back-and-forth transporting mechanism  630  is disposed for implementing back-and-forth movement of the transporting mechanism  600 . As illustrated in  FIG. 5 , the pull-out plate back-and-forth transporting mechanism  630  mainly includes a back-and-forth driving motor  631 , a wire (not illustrated in the figure) and a wire support portion  632 . In conjunction with driving of the back-and-forth driving motor  631 , the wire is configured to be moved along the wire support portion  632 . In conjunction with the wire movement, the transporting mechanism  600  is configured to be moved back and forth. 
     (6-4) Actions of Folding Device 
     Actions of the folding device  400  will be hereinafter explained with reference to  FIGS. 4 to 14 . 
     In the folding device  400 , the folding mechanism  500  is firstly set to be in a state illustrated in  FIG. 5 . In other words, the folding device  400  is set to be in a state (initial state) that the folding plates  511  to  514  are hung down roughly in the vertical direction in a front view. In the state, a laundry LD is put on the platen plates  501 . It should be noted that the width between the platen plates  501  is adjusted by the inter-platen-plate distance adjusting mechanism  530  as described above. 
     Next, the inner shaft rotary motor  522  of the dual nested shaft rotary mechanism  520  rotates the second folding plate  512  leftward (clockwisedly) at an angle of roughly 90 degrees in  FIG. 7  (see an arrow R 1  in  FIG. 7 ). The second folding plate  512  is thereby set to be in a state illustrated in  FIG. 7  (a second state). In other words, the second folding plate  512  is disposed adjacent to the bottom face of the platen plate  501 . It should be herein noted that a part of the laundry LD, hung down from the right side of the platen plates  501  in  FIG. 7 , is interposed and folded between the second folding plate  512  and the platen plate  501 . 
     Next, the inner shaft rotary motor  522  of the dual nested shaft rotary mechanism  520  rotates the first folding plate  511  rightward (counterclockwisedly) at an angle of roughly 90 degrees in  FIG. 8  (see an arrow R 2  in  FIG. 8 ). The first folding plate  511  is thereby set to be in a state illustrated in  FIG. 8  (a third state). In other words, the first folding plate  511  is disposed adjacent to the bottom face of the second folding plate  512 . It should be herein noted that a part of the laundry LD, hung down from the left side of the platen plates  501  in  FIG. 8 , is interposed and folded between the first folding plate  511  and the second folding plate  512 . 
     Next, the outer shaft rotary motor  523  of the dual nested shaft rotary mechanism  520  rotates the fourth folding plate  514  leftward (clockwisedly) at an angle of roughly 90 degrees in  FIG. 9  (see an arrow R 3  in  FIG. 9 ). The fourth folding plate  514  is thereby set to be in a state illustrated in  FIG. 9  (a fourth state). In other words, the fourth folding plate  514  is disposed adjacent to the bottom face of the first folding plate  511 . It should be herein noted that a part of the laundry LD, hung down from the right side of the first folding plates  511  in  FIG. 9 , is interposed and folded between the fourth folding plate  514  and the first folding plate  511 . 
     Next, the outer shaft rotary motor  523  of the dual nested shaft rotary mechanism  520  rotates the third folding plate  513  rightward (counterclockwisedly) at an angle of roughly 90 degrees in  FIG. 10  (see an arrow R 4  in  FIG. 10 ). The third folding plate  513  is thereby set to be in a state illustrated in  FIG. 10  (a fifth state). In other words, the third folding plate  513  is disposed adjacent to the bottom face of the fourth folding plate  514 . It should be herein noted that a part of the laundry LD, hung down from the left side of the fourth folding plate  514  in  FIG. 10 , is interposed and folded between the third folding plate  513  and the fourth folding plate  514 . 
     Next, the pull-out plate up-and-down transporting mechanism  610  lifts up the pull-out plate  601  to a predetermined height as illustrated in  FIG. 11  (a second state). The pull-out plate back-and-forth transporting mechanism  630  then forwardly moves the pull-out plate  601  to a predetermined position as illustrated in  FIG. 12  (a third state). It should be noted that the pull-out plate  601  is herein positioned while the plate face thereof is arranged along the vertical direction Dv. The pull-out plate rotary mechanism  620  then rotates the pull-out plate  601  to a position where the pull-out plate  601  is disposed roughly in parallel to the third folding plate  513  as illustrated in  FIG. 13  (a fourth state). 
     Subsequently, the right-side folding plate sliding mechanism  540  rightwardly slides and moves the right-side dual nested shaft rotary mechanism  520  in  FIG. 10 , while the left-side folding plate sliding mechanism  540  leftwardly slides and moves the left-side dual nested shaft rotary mechanisms  520  in  FIG. 10  (see arrows L 1  and L 2  in  FIG. 14 ). The folding device  400  is thereby set to be in a state illustrated in  FIG. 14  (a sixth state). The folding plates  511  to  514  are herein removed from the laundry LD, and the laundry LD can be easily pulled out by means of the pull-out plate  601 . 
     Then, the pull-out plate  601  is lifted down by the pull-out plate up-and-down transporting mechanism  610 , while being backwardly moved by the pull-out plate back-and-forth transporting mechanism  630 . The pull-out plate  601  is thereby set to be in a state illustrated in  FIG. 4 . 
     Subsequently, the pull-out plate rotary mechanism  620  rotates the pull-out plate  601  to a position where the pull-out plate  601  is downwardly tilted. With the action, the folded laundry LD on the pull-out plate  601  slips down to a sorting table  720  disposed below in a stand-by state.

     When receiving the identification number data D 0 , the control device  900  is configured to check the identification number data D 0  against the matching table Tr stored in the storage unit  930  and derive the platen plate width data D 1  and the storage position data D 2 , both of which are associated with the identification number data D 0 . Subsequently, the control device  900  is configured to send the platen plate width data D 1  to the folding device  400 , and simultaneously, send the storage position data D 2  to the sorting device  700 . 
     When receiving the platen plate width data D 1  and a fourteenth command signal, the folding device  400  is configured to adjust the width between the platen plates  501  based on the platen plate width data D 1 . When completing the width adjustment, the folding device  400  is then configured to send an adjustment completion notifying signal to the control device  900 . When receiving the adjustment completion notifying signal, the control device  900  is configured to send the fourteenth command signal to the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320 . When receiving the fourteenth command single, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  are configured to put the laundry LD on the platen plates  501  of the folding device  400 . 
     After unclamping the laundry LD, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  are subsequently configured to send a laundry release notifying signal to the control device  900 . When receiving the laundry release notifying signal, the control device  900  is then configured to send a fifteenth command signal to the folding device  400 . 
     When receiving the fifteenth command signal, the folding device  400  is configured to fold the laundry LD and transport the folded laundry LD to the sorting table  720  of the sorting device  700 . When completing transportation of the laundry LD to the sorting table  720 , the folding device  400  is configured to send a transport completion notifying signal to the control device  900 . When receiving the transport completion notifying signal, the control device  900  is configured to send a tenth command signal to the dried laundry transporting robot arm  320 . When receiving the tenth command signal, the dried laundry transporting robot arm  320  is configured to pick up one of the dried laundries LD from the drying machine  250  and halt at a predetermined position. The aforementioned processing will be subsequently repeated as described above. 
     Next, the control device  900  is configured to send a sixteenth command signal to the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  and send a seventeenth command signal to the drying machine  250 , when a sensor value of the second weight sensor (see  FIG. 2 ) embedded in the drying machine  250  reaches a fourth threshold (i.e., when the dryer drum becomes empty). When receiving the sixteenth command signal, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  are configured to automatically stop. When receiving the seventeenth command signal, on the other hand, the drying machine  250  is configured to close the lid thereof. 
     Meanwhile, when receiving the storage position data D 2  and an eighteenth command signal, the sorting device  700  is configured to cause one of the sorting table detection sensors corresponding to the storage position data D 2  to execute a sensing processing (i.e., cause the light emitter thereof to irradiate light to the light receiver thereof) and cause the other sorting table detection sensors to stop executing a sensing processing (i.e., cause the light emitters thereof to stop irradiating light). Accordingly, the sorting table  720  is configured to stop in front of one of the transporting tables  810   a  to  810   d  corresponding to the storage position data D 2 . 
     Next, the sorting device  700  is configured to send a detection notifying signal of the sorting table detection sensor to the control device  900 . When receiving the detection notifying signal, the control device  900  is configured to send a nineteenth command signal to the sorting device  700 . 
     Next, when receiving the nineteenth command signal, the sorting device  700  is configured to cause the 90-degree rotary mechanism to rotate the platen plate  730  at an angle of 90 degrees (see the platen plate  730  depicted with a broken line in  FIG. 15 ) and then cause the tilting mechanism to tilt the platen plate  730  so that the plate face of the platen plate  730  is downwardly tilted towards the corresponding one of the platen plates  840   a  to  840   d  of the transporting tables  810   a  to  810   d . Accordingly, the laundry LD slides down onto one of the transporting tables  810   a  to  810   d  corresponding to the storage portion data D 2  from the platen plate  730  of the sorting table  720  (see  FIG. 15 ). 
     When the laundries LD are thus laminated on each of the transporting tables  810   a  to  813   d  to a predetermined height, the top one of the laundries LD is detected by the level sensor. When confirming detection by the level sensor, the transporting device  800  is configured to send a detection notifying signal to the control device  900 . When receiving the detection notifying signal, the control device  900  is configured to send a twentieth command signal to the transporting device  800 . When receiving the twentieth command signal, the transporting device  800  is configured to drive one of the transporting tables  810   a  to  810   d  corresponding to the aforementioned level sensor by means of the corresponding one of the transporting mechanisms  820   a  to  820   d . Further, the transporting device  800  is configured to cause the corresponding one of the transporting tables  810   a  to  810   d  to stop in front of one of the storage spaces corresponding to the storage position data D 2  and then push the piston for moving the laundry LD to the storage space corresponding to the storage position data D 2 . 
     &lt;Features of Automatic Wash-Dry-Fold System&gt; 
     (1) 
     The automatic wash-dry-fold system  100  according to the present exemplary embodiment is configured to completely automatically wash, dry, fold, sort and store laundries. Therefore, the automatic wash-dry-fold system  100  only requires a worker to put laundries on a laundry basket. Therefore, it is possible to remarkably reduce worker&#39;s workload required for washing, drying and folding laundries. 
     (2) 
     In the automatic wash-dry-fold system  100  according to the present exemplary embodiment, the RFID tag reader  332  is configured to obtain the identification number data D 0  from the RFID tags and the control device  900  is configured to check the identification number data D 0  against the matching table Tr. Accordingly, the platen plate width data D 1  and the storage position data D 2  are derived based on the matching. Therefore, the RFID tags are required to hold a less amount of information in the automatic wash-dry-fold system  100 . As a result, the automatic wash-dry-fold system  100  can reduce the cost required for the RFID tags and reduce chances of causing troubles, for instance, in repurchase of fabric products (e.g., clothing). 
     (3) 
     The automatic wash-dry-fold system  100  according to the present exemplary embodiment is provided with the sorting device  700 . Further, the sorting device  700  is configured to sort the laundries LD based on the storage position data D 2 . Therefore, the automatic wash-dry-fold system  100  can sort the laundries LD based on owners of the laundries LD or storage positions. Therefore, the automatic wash-dry-fold system  100  can eliminate sorting-related workload of a worker. 
     (4) 
     The automatic wash-dry-fold system  100  according to the present exemplary embodiment is provided with the transporting device  800 . Further, the transporting device  800  is configured to move the laundries LD to the storage spaces based on the storage position data D 2 . Therefore, the automatic wash-dry-fold system  100  can eliminate a storage-related workload of a worker. 
     (5) 
     In the present exemplary embodiment, all the laundries LD include the passive-type RFID tags (not illustrated in the figures) attached thereto at two predetermined positions (e.g., “a shoulder part” for a shirt, “a waist part” for pants, etc.). Further, the automatic wash-dry-fold system  100  according to the present exemplary embodiment is provided with three RFID tag readers  331  to  333  configured to detect the positions of the RFID tags by means of the triangulation method. Yet further, the automatic wash-dry-fold system  100  is provided with the laundry transporting robot arm  310 , the dried laundry transporting robot arm  320  and the control device  900 . Therefore, the automatic wash-dry-fold system  100  can cause the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  to easily clamp the laundry LD at appropriate clamping positions. Therefore, the automatic wash-dry-fold system  100  can properly put the laundry LD on the platen plates  501  of the folding device  400 . 
     &lt;Modifications&gt; 
     (A) 
     In the aforementioned exemplary embodiment, the RFID tags contain the identification number data D 0 . However, the RFID tags may contain the platen plate width data D 1  and the storage position data D 2  instead of the identification number data D 0 . With the configuration, the matching table Tr and the matching processing are not required. 
     (B) 
     The automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment uses the RFID tags as the storage media of the identification number data D 0 . However, a barcode (e.g., a one-dimensional barcode, a two-dimensional barcode, etc.) may be used as the storage medium of the identification number data D 0 . It should be noted that a barcode reader is herein required instead of the RFID tag readers  331  to  333 . Further, the positional detection of the barcode is herein very difficult. Therefore, the positional detection is not herein executed and a worker is required to manually cause the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  to clamp the laundry LD. Yet further, the barcode is herein preferably attached to the lining of the laundry LD without being outstandingly visible to the outside. 
     Moreover, the platen plate width data D 1  and the storage position data D 2  may be converted into barcodes without using the identification number data D 0 , as described in the aforementioned exemplary modification (A). 
     (C) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, the identification number data D 0  of the RFID tags is configured to be checked against the matching table Tr and the platen plate width data D 1  and the storage position data D 2  are configured to be derived therefrom. However, the following configuration may be employed instead of the above. 
     First, an imaging device such as a camera is configured to preliminarily obtain the imaging data of the laundry LD or the imaging data of a distinctive part of the laundry LD. Then, a matching table is preliminarily created by associating the imaging data with the platen plate width data D 1  and the storage position data D 2 . It should be herein noted that the imaging data may be obtained by irradiating light or the like from the back of the laundry LD. 
     Next, the imaging device such as a camera images the laundry LD, and the control device  900  checks the imaging data (either partially or entirely) against the aforementioned matching table and derives the platen plate width data D 1  and the storage position data D 2  therefrom. 
     It should be herein noted that the imaging device used for creating the matching table and the imaging device used for checking the matching table may be identical to or different from each other. When the imaging data of the entirety of the laundry LD is used for creating the matching table, positional detection is quite difficult. Therefore, a worker is required to manually cause the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  to clamp the laundry LD without executing positional detection. By contrast, when the imaging data of the distinctive part of the laundry LD is used for creating the matching table, positional detection of the distinctive part may be executed and the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  may be caused to clamp the distinctive part of the laundry LD. 
     (D) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, the RFID tags are used as the storage media of the identification number data D 0 . However, fluorescent paint of a variety of colors may be used as the storage media of the identification number data D 0 . It should be herein noted that a black light and an imaging device are required instead of the RFID tag readers  331  to  333 . Further, barcodes may be herein formed using the fluorescent paints. 
     In this case, a matching table is preliminarily created by associating the data of colors and/or shapes of the fluorescent paint with the platen plate width data D 1  and the storage position data D 2 . Further, the laundry LD is imaged while being irradiated by a black light. The control device  900  checks the color and/or the shape of the fluorescent paint in the imaging data (either partially or entirely) against the aforementioned matching table and derives the platen plate width data D 1  and the storage position data D 2  therefrom. 
     It should be herein noted that the fluorescent paint may be applied to two predetermined positions (e.g., “a shoulder part” of a shirt, “a waist part” of pants, etc.) and positional detection of the fluorescent-paint applied parts may be executed. Further, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  may be caused to clamp the fluorescent-paint applied parts of the laundry LD. 
     Moreover, the platen plate width data D 1  and the storage position data D 2  may be converted into barcodes without using the data of the color and/or the shape of the fluorescent paint, as described in the aforementioned exemplary modification (A). 
     (E) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, the RFID tags are used as the storage media of the identification number data D 0 . However, metal pieces made of a variety of metal elements may be used as the storage media of the identification number data D 0 . It should be herein noted that a metal detector is required instead of the RFID tag readers  331  to  333 . 
     In this case, a matching table is preliminarily created by associating the data such as detection sensitivity with the platen plate width data. D 1  and the storage position data D 2 . Further, the metal detector is actuated with respect to the laundry LD, and the control device  900  checks the detection sensitivity of the metal detector against the matching table and derives the platen plate width data D 1  and the storage position data D 2  therefrom. 
     It should be herein noted that two metal pieces may be disposed on two predetermined positions (e.g., “a shoulder part” of a shirt, “a waist part” of pants, etc.) and positional detection of the metal pieces may be executed. Further, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  may be caused to clamp the metal piece embedded portions of the laundry LD. 
     (F) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, the RFID tags are used as the storage media of the identification number data D 0 . However, magnetic recording media may be used as the storage media for the identification number data D 0 . It should be herein noted that a magnetic recording reader is required instead of the RFID tag readers  331  to  333 . 
     It should be herein noted that two magnetic recording media may be disposed on two predetermined positions (e.g., “a shoulder part” of a shirt, “a waist part” of pants, etc.) and positional detection of the magnetic recording media may be executed. Further, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  may be caused to clamp the magnetic recording media embedded portions of the laundry LD. 
     Moreover, the platen plate width data D 1  and the storage position data D 2  may be stored instead of the identification number data D 0 , as described in the aforementioned exemplary modification (A). 
     (G) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, the transporting device  800  is configured to move the laundry LD sorted by the sorting device  700  to one of the storage spaces corresponding to the storage position data D 2 . Alternatively, an automatic wash-dry-fold system  100   a  may be structured as illustrated in  FIG. 17 . In the automatic wash-dry-fold system  100   a , the laundry LD sorted by the sorting device  700  is transported by means of free fall. 
     It should be noted that the automatic wash-dry-fold system  100   a  as described above includes falling spaces  870   a  to  870   d  for the sections  850   a  to  850   d , respectively, and each of the storage spaces is provided with a pull-in slide plate  880 . In response to a command from the control device  900 , a driving device (not illustrated in the figure) is configured to drive the pull-in slide plates  880  to protrude towards the falling spaces for receiving the falling laundries LD and then retract the pull-in slide plates  880  for pulling the received laundries LD into the storage spaces. The configuration is expected to contribute to energy saving. 
     (H) 
     In the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment, laundries are completely automatically washed, dried, folded, sorted and stored. However, laundries may be manually washed and dried. In this case, the laundry LD may be manually taken out of the drying machine  250  and may be manually passed over the RFID tag readers  331  to  333 . Subsequently, the laundry transporting robot arm  310  and the dried laundry transporting robot arm  320  may be manually caused to clamp the laundry LD. Even in this configuration, a worker is only required to execute a work for assisting input of the identification number data D 0  into the control device  900  (e.g., a work for taking a fabric product closer to the control device  900 ). Therefore, it is possible to reduce worker&#39;s workload required for width adjustment of the platen plates  501 . 
     The washing machine  200  as described above is employed in the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment. However, any other washing machines may be employed without departing from the scope of the present invention.

However, any other robot arms may be employed without departing from the scope of the present invention. 
     (L) 
     The flip-up-to-the-bottom type folding mechanism  500  is employed for the folding device  400  in the automatic wash-dry-fold system  100  of the aforementioned exemplary embodiment. However, a rotary type folding mechanism, a flip-up-to-the-top type folding mechanism or a slide type folding mechanism may be employed as the folding mechanism of the present invention.
