     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.  FIGS. 1 to 2B  show work device  1  according to an embodiment of the present disclosure. Work device  1  is a device that transmits data to feeder carriage  10  of component mounter  2  shown in  FIG. 3  as a work object. First, a configuration of component mounter  2  will be described. 
     In  FIG. 3 , component mounter  2  includes base  11 , board transport device  12  provided on base  11 , feeder carriage  10  connected to base  11 , parts feeder  13  installed on feeder carriage  10 , and installing head  14 . Board transport device  12  is configured of a pair of conveyor mechanisms, and transfers board KB supplied from an upstream process to be positioned at a predetermined position. Parts feeder  13  supplies component BH to component supply port  13 K in a state in which feeder carriage  10  is connected to base  11 . Installing head  14  has nozzle  15  for sucking component BH, and reciprocates between parts feeder  13  and board KB to install component BH supplied by parts feeder  13  on board KB. When all components BH to be installed on board KB are installed by installing head  14 , board transport device  12  transfers board KB to a downstream process. 
     In component mounter  2  having such a configuration, feeder carriage  10  is used as a support base for parts feeder  13 . As shown in  FIGS. 4A and 4B , feeder carriage  10  has base part  22  provided with four wheels  21  on front, rear, left, and right sides. Feeder base  23  is provided above base part  22 . 
     In  FIGS. 4A and 4B , feeder base  23  has left and right side plates  23 S on right and left sides, and has back plate  23 H on a back side (a side close to base  11  in a case where feeder carriage  10  is connected to base  11 ). A plurality of parts feeders  13  can be installed on feeder base  23 . Left and right handles  24  operated by worker OP shown in  FIG. 3  are provided on the left and right sides of base part  22 , worker OP can make feeder carriage  10  travel on floor surface FL shown in  FIG. 2B  by operating left and right handles  24 . 
     As shown in  FIG. 3 , base  11  is provided with connector  11 K. In  FIGS. 3 and 4B , connector  25  fitted to connector  11 K is provided on base-facing surface  22 F on the back side of base part  22 . When feeder carriage  10  is connected to base  11 , worker OP operates left and right handles  24  to make feeder carriage  10  travel on floor surface FL in a state in which base-facing surface  22 F faces base  11 . Then, feeder carriage  10  is brought close to base  11  after making connector  25  face connector  11 K. When feeder carriage  10  is located within a certain range with respect to base  11 , the approach of feeder carriage  10  is detected by a sensor (not shown), and feeder carriage  10  is connected to base  11  by a connection mechanism (not shown). When feeder carriage  10  is connected to base  11  in this manner, connector  25  is fitted to connector  11 K ( FIG. 3 ). 
     When feeder carriage  10  is connected to base  11  and connector  25  is fitted to connector  11 K, controller  10 C provided in feeder carriage  10  and control device  11 C of base  11  are electrically connected to each other, and data can be transmitted between controller  10 C and control device  11 C. In addition, by separating feeder carriage  10  connected to base  11  from base  11  and pulling out connector  25  from connector  11 K, the electrical connection between controller  10 C of feeder carriage  10  and control device  11 C of base  11  can be released. 
     Feeder carriage  10  can be connected to and separated from base  11  by worker OP operating left and right handles  24  as described above, or by using automated guided vehicle  30  shown in  FIGS. 5A and 5B . In a case where automated guided vehicle  30  is used, unmanned work is performed without human intervention. 
     As shown in  FIGS. 5A and 5B , automated guided vehicle  30  has traveling body  31  that travels on floor surface FL and top plate  32  that can be raised up and lowered with respect to traveling body  31 , and is wirelessly controlled by a traveling controller (not shown) to autonomously travel on floor surface FL and raise and lower top plate  32 . When automated guided vehicle  30  lifts and supports feeder carriage  10 , automated guided vehicle  30  travels on floor surface FL to enter space below bottom  10 S of feeder carriage  10  (arrow A shown in  FIG. 5A ), raises top plate  32  (arrow B shown in  FIG. 5B ), and lifts and supports feeder carriage  10  ( FIG. 5B ). Automated guided vehicle  30  that lifts and supports feeder carriage  10  autonomously travels on floor surface FL, and connects feeder carriage  10  to base  11  by bringing feeder carriage  10  close to base  11  after making connector  25  face connector  11 K ( FIG. 6A  to  FIG. 6B ). 
     As feeder carriage  10  connected to component mounter  2 , one of two types of feeder carriages  10  having different horizontal dimensions is used according to a type of component mounter  2 . In the present embodiment, of the two types of feeder carriages  10 , feeder carriage  10  having a larger horizontal dimension is referred to as wider carriage  10 A shown in  FIG. 7A , and feeder carriage  10  having a smaller horizontal dimension is referred to as narrower carriage  10 B shown in  FIG. 7B . 
     Next, work device  1  will be described. As described above, work device  1  is a device that transmits data to feeder carriage  10  as a work object. Specifically, the work of transmitting data to feeder carriage  10  through connector  25  of feeder carriage  10  is performed. Here, L-axis, W-axis, and Z-axis as shown in  FIG. 1  are defined as coordinate axes for convenience of describing a configuration of work device  1 . The L-axis is an axis extending in a front-rear direction of work device  1 , and the W-axis is an axis extending in a horizontal direction of work device  1 . The Z-axis is an axis extending in a vertical direction of work device  1 . 
       FIGS. 1 to 2B , work device  1  has main body  41 , left and right guides  42 , and data transmitter  43 . Main body  41  is formed in a box shape as a whole, and has connector part  41 K fitted to connector  25  of feeder carriage  10  on a front surface. Left and right guides  42  are provided so as to project from the front surface of main body  41  in a substantially horizontal direction. Guide  42  guides feeder carriage  10  so that connector  25  is fitted to connector part  41 K when feeder carriage  10  is brought close to main body  41  while making connector  25  face connector part  41 K (details will be described later). Therefore, connector  25  can be reliably fitted to connector part  41 K. Connector part  41 K may be disposed in an optimum direction (longitudinal direction, diagonal direction, or the like) according to a shape of connector  25 . In addition, connector part  41 K may be provided so as to be housed inside main body  41  without projecting from main body  41 . 
     Data transmitter  43  is provided in main body  41  and transmits various items of data (for example, work data of parts feeder  13 ) to feeder carriage  10  through connector  25  fitted to connector part  41 K. Connector part  41 K is configured to be able to be fitted to both connector  25  of wider carriage  10 A and connector  25  of narrower carriage  10 B. 
     As shown in  FIG. 1 , connector lock  41 L is provided in the vicinity of connector part  41 K on the front surface of main body  41 . Connector lock  41 L operates so that connector  25  is locked to main body  41  when connector  25  is fitted to connector part  41 K. 
     In  FIGS. 1 to 2B , main body  41  has bottom floor  51 , intermediate floor  52 , upper frame  53 , four pillars  54 , horizontal crosspiece  55 , two vertical crosspieces  56 , two guide attachment plates  57 , wheel stop base  58 , and a plurality of wheel stops  59 . Bottom floor  51 , intermediate floor  52 , and upper frame  53  each have a rectangular shape, and are disposed in this order from the lower side. Four corners of bottom floor  51 , intermediate floor  52 , and upper frame  53  are supported by four pillars  54  extending vertically. 
     In  FIGS. 1 to 2B , upper frame  53  has two left and right front-rear bars  53   a  extending along the L-axis, two front and rear horizontal bars  53   b  extending along the W-axis, and two intermediate front-rear bars  53   c  provided between two front-rear bars  53   a  along the L-axis. Data transmitter  43  is attached to intermediate floor  52 . Connector part  41 K is electrically connected to data transmitter  43 , and opens forward from a region between intermediate floor  52  and upper frame  53 . 
     In  FIGS. 1 to 2B , horizontal crosspiece  55  is located between intermediate floor  52  and front horizontal bar  53   b , extends along the W-axis, and both ends thereof are supported by two front pillars  54 . Two vertical crosspieces  56  extend along the Z-axis, and upper and lower ends thereof are respectively supported by vertical crosspiece  56  and front horizontal bar  53   b . As shown in  FIG. 8 , two guide attachment plates  57  have upper edges supported by intermediate front-rear bars  53   c  and front edges supported by vertical crosspieces  56 . 
     In  FIGS. 1 to 2B , wheel stop base  58  extends from bottom floor  51  to the front side and is located on floor surface FL. Each of the plurality of wheel stops  59  is provided on an upper surface of wheel stop base  58 . The plurality of wheel stops  59  have left and right outer wheel stops  59   a  compatible with wider carriage  10 A and left and right outer wheel stops  59   b  compatible with narrower carriage  10 B. Since a distance between left and right wheels  21  of wider carriage  10 A is larger than a distance between left and right wheels  21  of narrower carriage  10 B, a (horizontal) distance between left and right outer wheel stops  59   a  along the W-axis is larger than a distance between left and right inner wheel stops  59   b  along the W-axis. 
     In  FIGS. 1 to 2B , left and right guides  42  are compatible with two types of feeder carriages  10  (wider carriage  10 A and narrower carriage  10 B) having different horizontal dimensions, and have two types (outer guide  61  and inner guide  62 ) having different horizontal distances. Of these two types of left and right guides  42 , a pair of left and right outer guides  61  disposed on the left and right sides is compatible with wider carriage  10 A having a larger horizontal dimension, and a pair of left and right inner guides  62  disposed on the left and right sides is compatible with narrower carriage  10 B having a smaller horizontal dimension. In this way, work device  1  is compatible with wider carriage  10 A and narrower carriage  10 B having a horizontal dimension smaller than that of wider carriage  10 A as feeder carriage  10 . 
     Left and right outer guides  61  have a distance slightly larger than a distance between left and right side plates  23 S of wider carriage  10 A, and guide left and right side surfaces (outer surfaces of left and right side plates  23 S) of wider carriage  10 A so that connector  25  of wider carriage  10 A is fitted to connector part  41 K of work device  1  when wider carriage  10 A is brought close to main body  41 . In addition, left and right inner guides  62  have a distance slightly larger than a distance between left and right side plates  23 S of narrower carriage  10 B, and guide left and right side surfaces of narrower carriage  10 B so that connector  25  of narrower carriage  10 B is fitted to connector part  41 K of work device  1  when narrower carriage  10 B is brought close to main body  41 . 
     In  FIGS. 1 to 2B , left and right outer guides  61  and left and right inner guides  62  are respectively disposed such that intermediate positions of lengths (horizontal length) along the W-axis coincide with the center of a length of main body  41  along the W-axis. Each of left and right outer guides  61  has a rear portion fixed to two front and rear pillars  54  of main body  41  and extends in a substantially horizontal direction, and has a front end (tip end) projecting and extending to the front side of main body  41 . The tip end of each of left and right outer guides  61  is located at a height of each of left and right side plates  23 S of feeder carriage  10 . 
     In  FIGS. 8 to 9B , inner guide  62  is attached to each of two guide attachment plates  57  of main body  41  via linearly extending guide rail  71  and slider  72  moving freely on guide rail  71 . Guide rail  71  is attached to an inner surface side of guide attachment plate  57  (a side directed to the center of main body  41 ), and slider  72  moves (slides) freely on an inner surface side of guide rail  71 . Guide rail  71  and slider  72  are configured as a unit (slide pack). 
     Inner guide  62  is attached to slider  72 . Therefore, inner guide  62  can move (slide) along guide rail  71  integrally with slider  72 , and can move between a position at which inner guide  62  project forward from main body  41  (projection position.  FIG. 9A ) and a position at which inner guide  62  are stored in main body  41  (storage position.  FIG. 9B ). 
     As shown in  FIGS. 8 to 9B  and  FIG. 10 , each of left and right guide rails  71  is provided in an inclined manner so that the tip end (front end) thereof is directed downward. Each of left and right inner guides  62  is located at the projection position by self-weight in a state in which the tip end thereof is not pressed toward main body  41 . The tip end of each of left and right inner guides  62  located at the projection position is located at a height of each of left and right side plates  23 S of feeder carriage  10 . 
     In  FIGS. 10 to 11B , roller  73  as an abutting member is attached to the tip end of each of left and right inner guides  62 . Roller support shaft  73 J is provided at the tip end of inner guide  62  so as to extend substantially vertically, and roller  73  is inserted into roller support shaft  73 J. Therefore, roller  73  is rotatable around roller support shaft  73 J at the tip end of inner guide  62 . 
     In  FIGS. 12A and 12B , inner guide  62  extends along the L-axis. Elongated hole  62 K extending along the L-axis is provided at the tip end of inner guide  62  (the end on the upper side of the paper in  FIGS. 12A and 12B ) (see also  FIGS. 11A and 11B ), and roller support shaft  73 J is inserted into elongated hole  62 K. Therefore, roller  73  can move a little with respect to the tip end of inner guide  62  together with roller support shaft  73 J within a range where roller support shaft  73 J can move within elongated hole  62 K. 
     In  FIGS. 10 to 12B , link mechanism  74  and lock pin  75  are provided on a lower surface side of each of left and right inner guides  62 . Link mechanism  74  is connected to roller support shaft  73 J, and lock pin  75  extends along the W-axis and moves in an axial direction thereof by link mechanism  74 . That is, lock pin  75  moves along the W-axis. 
     In  FIGS. 10 to 12B , link mechanism  74  has main arm  81  and sub arm  82 . The center of main arm  81  is supported by swing support shaft  81 P. Swing support shaft  81 P is provided at the center in a lengthwise direction on the lower surface side of inner guide  62 . That is, swing support shaft  81 P is provided at the center of inner guide  62  along the L-axis. Main arm  81  is swingable around swing support shaft  81 P in a plane parallel to the lower surface of inner guide  62 . 
     In  FIGS. 10 to 12B , one end side of sub arm  82  is pivotably connected to roller support shaft  73 J, and the other end side thereof is pivotably connected to a front end of main arm  81  by pivot shaft  82 P. As shown in  FIGS. 12A and 12B , main arm  81  extends substantially along the L-axis, and sub arm  82  extends obliquely with respect to the L-axis (that is, with respect to main arm  81 ). 
     In  FIGS. 12A and 12B , lock pin  75  is pivotably connected to a rear end of main arm  81  by lock pin attachment shaft member  75 P. Lock pin guide  62 H (see also  FIG. 8  and  FIGS. 10 to 11B ) extending downward from a side surface of inner guide  62  is formed on inner guide  62 . 
     In  FIGS. 12A and 12B , lock pin  75  penetrates lock pin guide  62 H toward the outside (the direction away from the center of main body  41 ) along the W-axis. Hereinafter, of left and right ends of lock pin  75 , an end that penetrates lock pin guide  62 H is referred to as outer end  75 T. 
     In  FIGS. 11A to 12B , spring pressing member  76  is provided on the lower surface of inner guide  62 . Spring pressing member  76  has flange  76 F extending downward, and flange  76 F is located facing lock pin guide  62 H along the W-axis ( FIGS. 12A and 12B ). 
     In  FIGS. 11A to 12B , return spring  77  is inserted into a position near flange  76 F of lock pin  75 . Return spring  77  is contracted between main arm  81  and flange  76 F, and lock pin  75  is in a state of being biased by return spring  77  to the outside on left and right as viewed from main body  41  (toward the left side of the paper in  FIGS. 12A and 12B ). 
     In a state in which inner guide  62  is located at the projection position and no rearward pressing force is applied to roller  73  (this state of inner guide  62  is referred to as an “initial state”), outer end  75 T of lock pin  75  is located at a position protruding outward from a side surface of slider  72  (overhanging position) ( FIG. 12A ). Outer end  75 T of lock pin  75  located at the overhanging position abuts on front edge  57 E of guide attachment plate  57  of main body  41  from the front ( FIGS. 10 and 13 ), and inner guide  62  is locked to main body  41 . 
     As described above, sub arm  82  extends obliquely with respect to main arm  81 . Therefore, when roller  73  of inner guide  62  in the initial state is pressed to the rear side (arrow P shown in  FIG. 12B ), roller support shaft  73 J moves rearward in elongated hole  62 K, and pivot shaft  82 P moves along the W-axis by sub arm  82  (arrow M shown in  FIG. 12B ). Accordingly, main arm  81  swings around swing support shaft  81 P (arrow R shown in  FIG. 12B ), so that lock pin  75  moves in a direction opposite to a direction in which pivot shaft  82 P moves while pressing and contracting return spring  77  (arrow D shown in  FIG. 12B ), and outer end  75 T of lock pin  75  is located at a “non-overhanging position” not protruding outward from the side surface of slider  72  ( FIG. 12A  to  FIG. 12B ). 
     When outer end  75 T of lock pin  75  is located at the non-overhanging position by pressing roller  73  of inner guide  62  in the initial state to the rear side, the lock of inner guide  62  with respect to main body  41  is released. Therefore, inner guide  62  slides rearward on guide rail  71  in accordance with the pressing thereof ( FIG. 9A  to  FIG. 9B , and is located at the storage position ( FIGS. 9B and 14 ). 
     In addition, when the pressing of inner guide  62  is released from the state in which inner guide  62  slides rearward, inner guide  62  moves forward by self-weight ( FIG. 9B  to  FIG. 9A ) and returns to the projection position ( FIG. 9A ). When inner guide  62  returns to the projection position, lock pin  75  is located at the overhanging position by a biasing force of return spring  77  until then, and outer end  75 T abuts on front edge  57 E of guide attachment plate  57 . Therefore, inner guide  62  is locked again ( FIGS. 9A, 10, and 13 ). 
     As described above, in the present embodiment, each of left and right inner guides  62  located at the projection position is locked to main body  41  by lock pin  75  provided on inner guide  62 , and when roller  73  provided at the tip end of inner guide  62  as an abutting member is pressed toward main body  41 , lock pin  75  operates in a direction of releasing the lock and sliding of inner guide  62  to the storage position is possible. 
     In a case where data is to be transmitted to feeder carriage  10  by work device  1 , feeder carriage  10  is brought close to main body  41  after connector  25  is placed in a posture to face connector part  41 K. In this case, worker OP or automated guided vehicle  30  brings feeder carriage  10  close to main body  41 . 
     Here, in a case where feeder carriage  10  that is brought close to main body  41  is narrower carriage  10 B ( FIG. 15A  to  FIG. 15B ), further approach to main body  41  is restricted when rear left and right wheels  21  ride on left and right inner wheel stops  59   b . At the same time, connector  25  is fitted to connector part  41 K ( FIG. 16A  to  FIG. 16B ). When connector  25  is fitted to connector part  41 K, narrower carriage  10 B is in a state of being connected to work device  1  ( FIGS. 15B and 16B ). When narrower carriage  10 B is brought close to main body  41 , the left and right side surfaces thereof (outer surfaces of left and right side plates  23 S) are guided by left and right inner guides  62  ( FIG. 16A  to  FIG. 16B ), so that connector  25  of narrower carriage  10 B is reliably connected to connector part  41 K of work device  1 . 
     On the other hand, in a case where feeder carriage  10  that is brought close to main body  41  is wider carriage  10 A ( FIG. 17A  to  FIG. 17B ), further approach to main body  41  is restricted when rear left and right wheels  21  ride on left and right outer wheel stops  59   a . At the same time, connector  25  is fitted to connector part  41 K ( FIG. 18A  to  FIG. 18B ). When connector  25  is fitted to connector part  41 K, wider carriage  10 A is in a state of being connected to work device  1  ( FIGS. 17B and 18B ). When wider carriage  10 A is brought close to main body  41 , the left and right side surfaces thereof (outer surfaces of left and right side plates  23 S) are guided by left and right outer guides  61  ( FIG. 18A  to  FIG. 18B ), so that connector  25  of wider carriage  10 A is reliably connected to connector part  41 K of work device  1 . 
     When feeder carriage  10  that is brought close to main body  41  is wider carriage  10 A, wider carriage  10 A moves to the side of main body  41  while pressing roller  73  provided at the tip end of each of left and right inner guides  62  rearward by back plate  23 H. Accordingly, link mechanism  74  of each of left and right inner guides  62  operates so that outer end  75 T of lock pin  75  is located at the non-overhanging position ( FIGS. 12A to 12B ), and the lock of left and right inner guides  62  to main body  41  is released. Therefore, left and right inner guides  62  are pressed by back plate  23 H of wider carriage  10 A to move rearward from the projection position ( FIG. 9A  to  FIG. 9B ), and are located at the storage position when connector  25  is fitted to connector part  41 K. Therefore, left and right inner guides  62  do not hinder the progress of wider carriage  10 A brought close to the side of main body  41 . 
     When connector  25  is fitted to connector part  41 K of work device  1  as described above, controller  10 C of feeder carriage  10  and data transmitter  43  of work device  1  are electrically connected to each other, and data transmission from data transmitter  43  to the side of feeder carriage  10  is possible. When the data transmission becomes possible, data transmitter  43  waits for the operation by worker OP (or automatically) and transmits required data to feeder carriage  10 . The data transmitted from data transmitter  43  is stored in a memory (not shown) of controller  10 C of feeder carriage  10  (or parts feeder  13 ). 
     When the data transmission to the side of feeder carriage  10  by data transmitter  43  is completed, feeder carriage  10  is separated from main body  41 . In this case, worker OP or automated guided vehicle  30  separates feeder carriage  10  from main body  41 . When wider carriage  10 A is separated from main body  41 , each of left and right inner guides  62 , which has been pressed rearward by wider carriage  10 A until then and located at the storage position, slides forward by self-weight and returns to the projection position. Then, when inner guide  62  returns to the projection position, lock pin  75  projects to the non-overhanging position by return spring  77  and abuts on front edge  57 E of guide attachment plate  57 , so that inner guide  62  is locked to main body  41  again. 
     As described above, in work device  1  according to the present embodiment, connector  25  can be fitted to connector part  41 K by bringing feeder carriage  10  close to main body  41  in a state of making connector  25  face connector part  41 K. In this case, since the left and right side surfaces of feeder carriage  10  are guided by left and right guides  42  that are provided so as to project from main body  41 , connector  25  is reliably fitted to connector part  41 K. Therefore, there is no need for worker OP to manually connect the connectors to each other, which is conventionally required, and workability of the work of transmitting data to the side of feeder carriage  10  (data transmission work) can be improved. 
     Work device  1  according to the present embodiment includes two types of left and right guides  42  (outer guide  61  and inner guide  62 ) compatible with two types of feeder carriages  10  (wider carriage  10 A and narrower carriage  10 B) having different horizontal dimensions, and even in a case where whichever of the two types of feeder carriages  10  is brought close to main body  41 , feeder carriage  10  is properly guided by guide  42  (outer guide  61  or inner guide  62 ) compatible with feeder carriage  10 . Therefore, the work (data transmission) can be performed on the two types of feeder carriages  10  having different horizontal dimensions in spite of single work device  1 , and workability of the data transmission work can also be improved in this aspect. In addition, since it is not necessary to prepare a plurality of work devices  1 , it is advantageous in terms of cost. Furthermore, there is no need for worker OP to manually connect the connectors to each other, so that, in a case where feeder carriage  10  is transferred by automated guided vehicle  30  and feeder carriage  10  is automatically connected to and separated from base  11  of component mounter  2  and work device  1  (in an unmanned manner), a greater effect is obtained. 
     Although the embodiments of the present disclosure have been described so far, the present disclosure is not limited to those described above, and various modifications and the like can be made. For example, in the above-described embodiment, left and right guides  42  that guide the left and right side surfaces of feeder carriage  10  brought close to main body  41  have left and right outer guides  61  and left and right inner guides  62 . This is because two types of feeder carriages  10  having different horizontal dimensions are work objects of work device  1 . Accordingly, when there is one type of feeder carriage  10  as a work object, work device  1  needs only have one type of left and right guides  42  compatible with the horizontal dimension of feeder carriage  10 .
