     A processing machine including a safety belt connection portion (locking tool) connecting the safety belt is known as disclosed in PTL 1 described above. The worker connects the safety belt attached to own body to the safety belt connection portion to ensure safety during working at a high place. However, depending on a position where the safety belt connection portion is provided, there is a possibility that it takes an excessive amount of time and effort when the worker uses the safety belt or the safety belt connection portion affects a maximum mechanical dimension of the processing machine. 
     An object of the present invention is to solve the above problems, and to provide a processing machine that has good workability when the worker uses the safety belt and is miniaturized. 
     Solution to Problem 
     A processing machine according to the present invention includes an external cover that forms an appearance of the processing machine and defines and forms an internal space, and a safety belt connection portion that is disposed in the internal space and to which a safety belt is connectable. The external cover includes an openable lid. The safety belt connection portion is exposed to an outside of the internal space through an opening that is generated in the external cover when the lid is in an open state. 
     According to the processing machine configured as described above, when performing an operation such as maintenance of the processing machine, the worker exposes the safety belt connection portion to the outside of the internal space through the opening by bringing the lid into the open state. As a result, the worker can connect the safety belt worn on own body to the safety belt connection portion, so that the workability can be improved when the worker uses the safety belt. In addition, the safety belt connection portion is disposed inside the external cover that forms the appearance of the processing machine, so that the safety belt connection portion is not disposed in the outermost shell of the processing machine. As a result, the processing machine can be downsized. 
     Preferably, the lid is disposed on a ceiling portion of the processing machine. According to the processing machine configured as described above, the safety belt connection portion is disposed inside the external cover in the ceiling portion of the processing machine, so that the safety belt connection portion does not affect a maximum machine height of the processing machine. 
     Preferably, the lid is supported by the safety belt connection portion. 
     According to the processing machine configured as described above, a configuration in which the safety belt connection portion is exposed through the opening that is generated when the lid portion is in the open state can be easily obtained. 
     Preferably, the processing machine further includes a support that rotatably or slidably supports the lid. When the lid is rotated or slid, the opening is generated in the external cover. 
     According to the processing machine configured as described above, the lid can be easily opened and closed, so that the workability can be further improved when the worker uses the safety belt. 
     Preferably, the external cover includes a plurality of lids that is openable and closable independently of each other. 
     According to the processing machine configured as described above, the opening can be provided at an appropriate position by bringing at least one of the plurality of lids into the open state according to a work place in the processing machine. 
     Preferably, the safety belt connection portion includes a frame portion extending in one direction along an opening plane formed by the opening. 
     According to the processing machine configured as described above, the safety belt connection portion can be prevented from largely closing the opening plane of the opening. Thus, the worker can easily perform work such as maintenance of the processing machine through the opening. 
     Preferably, the safety belt connection portion further includes a rope routed along the frame portion. 
     According to the processing machine configured as described above, the worker can connect the safety belt mounted on own body to the rope. 
     Preferably, the frame portion is made of a pipe member having a closed section. 
     According to the processing machine configured as described above, the safety of the worker who uses the safety belt can be enhanced by sufficiently securing rigidity of the safety belt connection portion. 
     Preferably, the processing machine further includes: an additive-manufacturing head that is disposed in a processing area, discharges material powder to a workpiece, and irradiates the workpiece with a laser beam; a line body that extends from the additive-manufacturing head, is drawn from an inside to an outside of the processing area, and supplies the material powder and the laser beam to the additive-manufacturing head; and a line body support that is provided outside the processing area to support the line body. The line body support is exposed to the outside of the internal space through the opening that is generated in the external cover when the lid is in the open state. 
     According to the processing machine configured as described above, the worker can maintain the line body support through the opening generated in the external cover while connecting the safety belt mounted on own body to the safety belt connection portion. 
     Advantageous Effects of Invention 
     As described above, the processing machine that has the good workability when the operator uses the safety belt and is miniaturized can be provided according to the present invention.

Air cylinder  382  includes a pin (not illustrated) movable forward and backward in the Y-axis direction. A state in which tool spindle  121  and line body support  221  are coupled to each other is obtained when the pins of air cylinder  382  is inserted into the pin insertion holes made in block  381 , and a state in which the coupling between tool spindle  121  and line body support  221  is released is obtained when the pins of air cylinder  382  is removed from the pin insertion holes made in block  381 . 
     During the additive manufacturing for the workpiece, tool spindle  121  and line body support  221  are coupled by coupling mechanism  380 , so that line body support  221  can be moved in the Z-axis direction integrally with tool spindle  121  and additive-manufacturing head  131 . During the subtractive manufacturing for the workpiece, when the coupling between tool spindle  121  and line body support  221  by coupling mechanism  380  is released, line body support  221  and additive-manufacturing head  131  can be separated from tool spindle  121 , and tool spindle  121  can be moved alone. 
     Line body support  221  is further configured to be movable in the Z-axis direction in a single state separated from tool spindle  121  (self-traveling mechanism).

While the coupling between tool spindle  121  and line body support  221  by coupling mechanism  380  is released, the pinion receiving the rotation from servomotor  222  rotates in a forward direction or a reverse direction, so that line body support  221  moves in the +Z-axis direction or the −Z-axis direction. 
       FIGS.  5  to  7    are front views schematically illustrating a processing flow of the workpiece in the processing machine in  FIG.  1   . 
     Referring to  FIGS.  5  to  7   , processing machine  100  further includes a laser tool storage portion  191  and a head storage portion  192 . Laser tool storage portion  191  is configured to be able to store a plurality of laser tools  133 . Head storage portion  192  is configured to be able to store additive-manufacturing head  131  separated from tool spindle  121  during subtractive manufacturing for the workpiece. 
     Laser tool storage portion  191  and head storage portion  192  are provided outside processing area  110 . Laser tool storage portion  191  is provided between first workpiece spindle  111  and the standby position of automatic tool changer  141  in the X-axis direction (vertical direction).

     As illustrated in  FIG.  5   , during the additive manufacturing for a workpiece W, additive-manufacturing head  131  is mounted on tool spindle  121 . When tool spindle  121  moves in the X-axis direction, the Y-axis direction, and the Z-axis direction, additive-manufacturing head  131  also moves in processing area  110  integrally with tool spindle  121 . Thus, the processing position of the additive manufacturing by additive-manufacturing head  131  is three-dimensionally displaced. Furthermore, when tool spindle  121  turns about turning axis  504 , additive-manufacturing head  131  also turns about turning axis  504  integrally with tool spindle  121 . Thus, the direction of the additive manufacturing by additive-manufacturing head  131  (the irradiation direction of the laser beam with respect to the workpiece) can be freely changed. 
     When additive-manufacturing head  131  is moved to the position opposite to laser tool storage portion  191  in the Z-axis direction, laser tool  133  mounted on additive-manufacturing head  131  can be replaced with another laser tool  133  stored in the laser tool storage portion  191 . 
     As illustrated in  FIG.  6   , when the subtractive manufacturing for workpiece W is performed subsequent to the additive manufacturing for workpiece W, the connection between tool spindle  121  and additive-manufacturing head  131  is released, and the connection between line body support  221  and saddle  161  is also released. Additive-manufacturing head  131  integrated with line body support  221  is moved from the inside of processing area  110  to head storage portion  192  outside processing area  110  by the self-traveling mechanism provided in line body support  221 . 
     On the other hand, tool spindle  121  from which additive-manufacturing head  131  is separated is turned by 90° about turning axis  504  from the reference posture. Automatic tool changer  141  is moved from the standby position to the internal-side tool changing position in processing area  110 . A tool Ta gripped by automatic tool changer  141  is mounted on tool spindle  121  by automatic tool changer  141 . When automatic tool changer  141  is moved from the internal-side tool changing position to the standby position, the mounting of the tool to tool spindle  121  is completed. 
     The internal-side tool changing position is appropriately set such that a movement amount of tool spindle  121  from the position of tool spindle  121  to the internal-side tool changing position at the start of tool change is shortened. The internal-side tool changing position set in this way may be selected from any coordinate in the Z-axis direction, or selected from a plurality of coordinate candidates in the Z-axis direction. 
     As illustrated in  FIG.  7   , during the subtractive manufacturing for workpiece W, the workpiece is milled by tool Ta held by tool spindle  121  while additive-manufacturing head  131  is stored in head storage portion  192 . 
     During this time, automatic tool changer  141  is moved from the standby position to the magazine-side tool changing position, and tool Tb stored in tool magazine  171  at the magazine-side tool changing position is moved to automatic tool changer  141 . Automatic tool changer  141  holding tool Tb is moved from the magazine-side tool changing position to the standby position to prepare for the next tool change in tool spindle  121 .

     With reference to  FIGS.  13  and  16   , when lid  721 B, lid  721 C, lid  721 H, and lid  721 N are the open state, opening  780  is formed in external cover  710 . Internal space  706  and the space outside internal space  706  communicate with each other through opening  780 . Opening  780  opens in the +X-axis direction (upward) and the −Y-axis direction. 
     Safety belt connection portion  750  is exposed to the outside of internal space  706  through opening  780 . Safety belt connection portion  750  is exposed to the outside of internal space  706  in a part of the length region of first beam  751  and rope  756  in the Z-axis direction. Safety belt connection portion  750  is opposite to an opening plane formed by opening  780  in the Y-axis direction and the X-axis direction. 
     First beam  751  extends in the Z-axis direction along the opening plane formed by opening  780 . First beam  751  is disposed immediately below the opening plane formed by opening  780 . 
     When lid  721 B, lid  721 C, lid  721 H, and lid  721 N are in the open state, line body support  221  is exposed to the outside of internal space  706  through opening  780 . Line body support  221  is opposite to the opening plane formed by opening  780  in the X-axis direction. The space above line body support  221  is opened in the +X-axis direction (upward) through opening  780 . 
     When lid  721 B, lid  721 C, lid  721 H, and lid  721 N are in the open state, footboard  716  is exposed to the outside of internal space  706  through opening  780 . Footboard  716  is opposite to the opening plane formed by opening  780  in the X-axis direction. The space above footboard  716  is opened in the −Y-axis direction and the +X-axis direction (upward) through opening  780 . 
     In top view, line body support  221  is located on the opposite side of footboard  716  across safety belt connection portion  750  (first beam  751  and rope  756 ). 
     With reference to  FIGS.  9 ,  13 , and  16   , there may be a need for maintenance of line body support  221  including tension applying mechanism  335 , coupling mechanism  380 , first guide mechanism  370 , second guide mechanism  360 , and the like. 
     In this case, the worker moves line body support  221  in the Z-axis direction to position line body support  221  immediately below lid  721 B and lid  721 C. The worker stands at the top of ladder  714  through corridor  712  and ladder  714 . 
     When revolving lid  721 H about rotating axis  531  to remove lid  721 N from external cover  710 , the worker opens lid  721 H and lid  721 N. When sliding lid  721 B in the +Z-axis direction to slide lid  721 C in the −Z-axis direction, the worker opens lid  721 B and lid  721 C. 
     The worker hangs hooks  762  of safety belt  761  mounted on own body on the rope  756  of safety belt connection portion  750 . The worker performs maintenance of line body support  221  through opening  780 . 
     In the embodiment, lids  721 B,  721 C,  721 H,  721 N that can be opened and closed are provided in external cover  710 , and safety belt connection portion  750  is provided at the position exposed to the outside of internal space  706  through opening  780  generated when lids  721 B,  721 C,  721 H,  721 N are opened. Thus, when opening lids  721 B,  721 C,  721 H,  721 N, the worker can hang hook  762  of safety belt  761  mounted on own body on rope  756  of safety belt connection portion  750 . Accordingly, the workability can be improved when the worker uses safety belt  761 . 
     In addition, safety belt connection portion  750  is disposed inside external cover  710  that forms the appearance of processing machine  100 . Thus, safety belt connection portion  750  does not affect the maximum mechanical dimension (height) of processing machine  100 , but processing machine  100  can be downsized. 
     In the embodiment, lid  721 B and lid  721 C are slidably supported, and lid  721 H is revolvably supported. With such the configuration, lid  721 B, lid  721 C, and lid  721 H can be easily opened and closed, so that the workability can be further improved when the worker uses safety belt  761 . 
     Lid  721 N is supported by first beam  751  of safety belt connection portion  750 . According to such the configuration, first beam  751  is disposed immediately on the back side of lid  721 N, so that the configuration in which safety belt connection portion  750  is exposed through opening  780  generated when lid  721  N is opened can be easily obtained. In addition, first beam  751  supporting external cover  710  is shared by safety belt connection portion  750  connecting safety belts  761 , so that the number of parts can be reduced. 
     First beam  751  extends in one direction along the opening plane formed by opening  780 . Thus, first beam  751  can be prevented from largely closing the opening plane formed by opening  780 . Accordingly, the worker can easily perform the maintenance of line body support  221  through opening  780 . 
     In the embodiment, although the case where the maintenance of line body support  221  is performed with lids  721 B,  721 C,  721 H,  721 N of the plurality of lids  721  in the open state has been described, this is an example. 
     The maintenance target is not limited to line body support  221 , but for example, may be automatic tool changer  141  or slide cover  351 . Lid  721  excluding lids  721 B,  721 C,  721 H is attached to the main body side of processing machine  100  such as first beam  751  and second beam  746  using bolts. Lid  721  excluding lids  721 B,  721 C,  721 H can be removed from the main body side of processing machine  100  by loosening the bolts. The worker can provide the opening at an appropriate position by bringing at least one lid  721  of the plurality of lids  721  into the open state according to the position of the maintenance target. 
     When the structure of processing machine  100  of the embodiment of the present invention described above is summarized, processing machine  100  of the embodiment includes external cover  710  that forms the appearance of processing machine  100  and defines and forms internal space  706 , and safety belt connection portion  750  that is disposed in internal space  706  and to which safety belt  761  can be connected. External cover  710  includes openable lid  721 . Safety belt connection portion  750  is exposed to the outside of internal space  706  through the opening that is generated in external cover  710  when lid  721  is in the open state. 
     According to processing machine  100  of the embodiment of the present invention configured as described above, the workability can be improved when the worker uses safety belt  761 , and processing machine  100  can be downsized. 
     In the embodiment, the case where the AM/SM hybrid processing machine is configured based on the combined processing machine having the turning function and the milling function has been described. However, the present invention is not limited to such the configuration, and for example, the AM/SM hybrid processing machine may be configured based on a machining center having the milling function. In addition, the present invention is not limited to the AM/SM hybrid processing machine, but may be applied to a lathe, a machining center, or a combined processing machine having a turning function and a milling function. 
     It should be considered that the disclosed embodiment is an example in all respects and not restrictive. The scope of the present invention is defined by not the description above, but the claims, and it is intended that all modifications within the meaning and scope of the claims and their equivalents are included in the present invention.
