JP 2002-151898 A

  By the way, in the thing of patent document 1, it is necessary to provide a cable bear in a X direction and a Y direction, respectively. For this reason, the number of members for protecting and guiding the cable increases, and the number of steps for attaching these members also increases.

  The present invention has been made in view of such circumstances, and its main purpose is to reduce the installation man-hour of the protection guide member in the attachment structure for attaching the cable protection guide member provided along two directions intersecting each other to the movable member. It is to reduce.

  The present invention employs the following means in order to solve the above problems.

  The first means is a mounting structure for attaching a cable protection guide member provided along a first direction and a second direction intersecting each other to the movable member, and the protection guide member is integrally formed in a long shape with resin. The protective guide member is formed in a rectangular shape having a hollow cross section perpendicular to the longitudinal direction, and slits perpendicular to the longitudinal direction are formed at predetermined intervals in the longitudinal direction. The protective guide member is extended along the first direction to a first folding position that crosses the intersection with the second direction, and the predetermined one surface is formed at the first folding position. Folded to the circumferential side, extended to the intersecting portion along the first direction, and twisted so as to go in the second direction with the predetermined one surface as an inner circumferential side at the intersecting portion, Extended along the second direction Characterized in that attached to the serial movable member.

  According to the said structure, a cable protection guide member is provided along the 1st direction and 2nd direction which mutually cross | intersect, and a protection guide member is attached to a movable member. Here, since the protective guide member is integrally formed in a long shape with resin, the structure of the protective guide member itself is simplified compared to a protective guide member that is assembled by connecting a large number of conventional link members and the like. And the assembly work can be omitted.

  Specifically, the protective guide member has a rectangular shape with a hollow cross section perpendicular to the longitudinal direction, and the protective guide member has a slit perpendicular to the longitudinal direction that cuts three surfaces except for one predetermined surface in the longitudinal direction. They are provided at predetermined intervals. For this reason, the protective guide member can be bent or twisted so that a predetermined one surface where no slit is provided is on the inner peripheral side and the interval between the slits on the outer peripheral side is widened. At this time, an action of maintaining the cross-sectional shape of the protective guide member is generated by a portion other than the predetermined one surface not provided with the slit and the three-surface slit provided with the slit. Therefore, the deformation of the protection guide member can be suppressed and the shape can be stabilized with respect to the weight of the protection guide member and the weight of the cable accommodated in the protection guide member.

  The protective guide member is extended along the first direction to the first folding position beyond the intersection with the second direction, and is folded with the predetermined one surface as the inner peripheral side at the first folding position. , Extending to the intersection along the first direction. That is, the protective guide member can be folded back by bending a predetermined one surface, which is not provided with slits, to the inner peripheral side and widening the gap between the outer peripheral slits.

  Further, the protection guide member is twisted so as to be directed in the second direction with a predetermined surface on the inner peripheral side at the intersection, and is extended along the second direction and attached to the movable member. That is, the protective guide member can be directed from the first direction to the second direction by twisting the predetermined one surface on the inner peripheral side and widening the interval between the slits on the outer peripheral side. When the movable member moves along the first direction, the first folding position moves along the first direction and the protective guide member is sent out, so that the cable can be guided by the protective guide member. it can. As a result, the attachment structure for attaching the protection guide member provided along two directions intersecting each other to the movable member can be realized by the protection guide member integrally formed in a long shape. Can be reduced.

  That is, by adopting the structure of the protective guide member and the mounting structure (bending and twisting with a predetermined one surface not provided with a slit on the inner peripheral side), even one protective guide member intersects 2 It is possible to arrange in one direction. For this reason, both bending with respect to the movement of the movable member along the first direction and twisting with respect to the direction change of the protective guide member from the first direction to the second direction can be achieved.

  In the second means, the protection guide member is twisted so as to be directed in the second direction, and then is extended along the second direction to a second folding position beyond the movable member, In the folded position, the sheet is folded with the predetermined one surface as an inner peripheral side, is extended along the second direction, and is attached to the movable member.

  According to the above configuration, the protective guide member is twisted in the second direction and then extended along the second direction to the second folding position beyond the movable member. One surface is folded back on the inner peripheral side. For this reason, when the movable member moves along the second direction, the cable is guided by the cable protection guide member by moving the second folding position along the second direction and feeding the protection guide member. be able to. As a result, even when the movable member moves in two directions of the first direction and the second direction, the cable can be protected and guided by the protective guide member integrally formed in a long shape.

  In the third means, movement of the protection guide member along the second direction is restricted at the intersection.

  According to the above configuration, since the protection guide member is restricted from moving along the second direction at the intersecting portion, a portion twisted so as to go in the second direction with the predetermined one surface as the inner peripheral side is provided. , Swinging can be suppressed. Even if the movement of the protective guide member along the second direction is restricted at the intersection, the movement of the first folding position and the second folding position is not hindered. Therefore, in the protective guide member, there is no problem in guiding the cable accompanying the movement of the movable member.

  In the fourth means, in the cross section perpendicular to the longitudinal direction of the protective guide member, the predetermined surface is curved inward, and the surface of the protective guide member that faces the predetermined surface is the protective member. It is divided into two along the longitudinal direction of the guide member.

  According to the above configuration, since the predetermined one surface is curved inward in the cross section perpendicular to the longitudinal direction of the protective guide member, the bending resistance of the protective guide member with the predetermined one surface as the inner peripheral side is improved. Can be made. Therefore, the deformation of the protection guide member can be effectively suppressed with respect to the weight of the protection guide member and the weight of the cable accommodated in the protection guide member. As a result, the shape of the protective guide member can be further stabilized.

  In addition, since the surface of the protective guide member that faces the predetermined one surface is divided into two along the longitudinal direction of the protective guide member, the cable can be easily inserted into the protective guide member from the crack.

  When the protective guide member is bent with the predetermined one surface as the inner peripheral side, the predetermined one surface is deformed so as to be extended. For this reason, the surfaces on both sides connected to the predetermined one surface are inclined so as to fall to the predetermined one surface side, and the divided portion of the surface connected to the both surfaces (the surface facing the predetermined one surface) is Then, it approaches the predetermined one side. For this reason, the crack of a protection guide member will be closed and it can suppress that a cable protrudes from the inside of a protection guide member. Therefore, the cable accommodated in the protective guide member can be firmly held even in the portion where the protective guide member is bent.

  In the fifth means, the end portion on the predetermined one surface side of the slit is rounded.

  According to the above configuration, since the end portion on the predetermined one surface side is rounded in the slit, when bending so as to widen the interval between the slits on the outer peripheral side with the predetermined one surface being the inner peripheral side, It can suppress that a crack arises in an end. As a result, the durability of the protective guide member can be improved.

  Hereinafter, an embodiment will be described with reference to the drawings. This embodiment is embodied as an attachment structure for attaching a cable protection guide member to an actuator that is moved by an XY table.

  FIG. 1 is a perspective view showing an attachment structure 10 for a cable protection guide member 30. As shown in the figure, the mounting structure 10 includes an XY table 20, an actuator 25, a cable 41, and a cable protection guide member 30. The XY table 20 is arranged horizontally. Note that the arrangement of the XY table 20 is not necessarily horizontal, and may be inclined or vertical.

  The XY table 20 includes a Y-axis table 21 and an X-axis table 22. The Y-axis table 21 includes a drive motor, a drive mechanism, and a mounting base 23. Then, the Y-axis table 21 moves the mounting base 23 in the Y direction (first direction) by the drive mechanism based on the drive of the drive motor. The X-axis table 22 includes a drive motor, a drive mechanism, and a mounting base 24. The X-axis table 22 moves the mounting base 24 in the X direction (second direction) by the drive mechanism based on the drive of the drive motor. The Y-axis direction and the X-axis direction are orthogonal to each other. Note that the Y-axis direction and the X-axis direction do not necessarily have to be orthogonal to each other as long as they intersect each other.

  An X-axis table 22 is attached to the mounting base 23 of the Y-axis table 21. On the other hand, an actuator 25 is attached to the mounting base 24 of the X-axis table 22. Then, by driving the Y-axis table 21, the entire X-axis table 22 and the actuator 25 attached to the mounting base 23 are moved in the Y-axis direction. On the other hand, the actuator 25 attached to the mounting base 24 is moved in the X-axis direction by driving the X-axis table 22. Therefore, the actuator 25 (movable member) is moved to an arbitrary position in the Y-axis direction and the X-axis direction by the XY table 20.

  A cable 41 is connected to the actuator 25. The cable 41 is an electrical wiring that supplies electric power from the outside to the actuator 25 and transmits a drive signal to the actuator 25. The actuator 25 is driven by electric power supplied through the cable 41 and is operated based on a drive signal transmitted through the cable 41. As the actuator 25, for example, a device for picking up electronic components can be employed.

  A cable protection guide member 30 is attached to the cable 41. The protective guide member 30 is provided along the Y-axis direction and the X-axis direction. The protection guide member 30 protects the cable 41 and guides the cable 41 in the Y-axis direction and the X-axis direction when the XY table 20 is driven.

  Next, the structure of the cable protection guide member 30 will be described in detail. FIG. 2 is a perspective view showing the protection guide member 30 and the cable 41.

  As shown in the figure, the protection guide member 30 is integrally formed in a long shape. The cross section perpendicular to the longitudinal direction of the protective guide member 30 is a hollow rectangular shape. The protective guide member 30 includes a curved surface 33, two side surfaces 34, and a dividing surface 35. The protective guide member 30 is provided with slits 36 perpendicular to the longitudinal direction at predetermined intervals in the longitudinal direction. The slit 36 cuts the dividing surface 35 and the two side surfaces 34 leaving the curved surface 33 (predetermined one surface), and cuts from the dividing surface 35 to the vicinity of the curved surface 33. In the slit 36, the end 36a on the curved surface 33 side is rounded.

  The dividing surface 35 that faces the curved surface 33 is divided into two along the longitudinal direction of the protective guide member 30. That is, a gap 37 extending in the longitudinal direction of the protective guide member 30 is formed on the dividing surface 35. The width of the gap 37 is set to be narrower than the diameter of the cable 41. The distance between the side surfaces 34 is set wider than the total diameter of the two cables 41. The distance between the curved surface 33 and the dividing surface 35 is set wider than the diameter of the cable 41.

  The protective guide member 30 is subjected to a process for forming the slit 36 and the gap 37 after extrusion molding of synthetic resin. For this reason, the length of the protection guide member 30 can be arbitrarily adjusted. As the synthetic resin, it is desirable to employ a resin having high mechanical strength and high molding accuracy. For example, polyolefin resins such as polyethylene and polypropylene, polyester resins, polyacrylic resins, polyvinyl chloride resins, and the like can be used. Here, polypropylene having high extrusion moldability and form stability and capable of elastic deformation is employed. The protective guide member 30 is elastically deformed so as to widen the gap 37, and the cable 41 is inserted into the protective guide member 30.

  The protection guide member 30 forms a straight portion that is linearly arranged, a folded portion that is folded back, and a twisted portion that is twisted when attached to the XY table 20.

  FIG. 3 is a cross-sectional view of the cable protection guide member 30 and the cable 41 in the straight portion. As shown in the figure, in the straight portion (natural portion), the curved surface 33 of the protective guide member 30 is curved inward (dividing surface 35 side). In this state, the two side surfaces 34 are substantially parallel to each other. The curved surface 33 and the side surface 34 are substantially equal in thickness, and the dividing surface 35 is thicker than the curved surface 33. The dividing surface 35 is inclined so that the end on the gap 37 side approaches the curved surface 33 side. For this reason, it is possible to increase the resistance force against the force acting on the dividing surface 35 from the cable 41, and to prevent the cable 41 from being detached from the protective guide member 30.

  FIG. 4 is a cross-sectional view of the cable protection guide member 30 and the cable 41 at the folded portion. At the folded portion, the protective guide member 30 is folded with the curved surface 33 as the inner peripheral side. In the figure, the protection guide member 30 and the cable 41 in the straight line portion are indicated by a two-dot chain line.

  As shown in the figure, when the protective guide member 30 is deformed so that the curved surface 33 is on the inner peripheral side, the curved surface 33 is deformed to be extended. For this reason, the curved surface 33 is deformed into a flat shape, and the two side surfaces 34 connected to both ends of the curved surface 33 in the width direction are inclined so as to fall toward the curved surface 33 side. Thereby, the dividing surface 35 connected to the side surface 34 is also inclined so that the end portion on the gap 37 side approaches the curved surface 33 side. As a result, the width of the gap 37 formed on the dividing surface 35 becomes narrow, and the cable 41 can be prevented from being detached from the protective guide member 30. In addition, since the dividing surface 35 is thicker than the curved surface 33, it is possible to increase a resistance force against a force acting on the dividing surface 35 from the cable 41. Therefore, it is possible to effectively prevent the cable 41 from being detached from the protective guide member 30.

  The cable protection guide member 30 and the cable 41 in the twisted portion are deformed so as to twist the cross section shown in FIG. Also in this case, the same effect as the folded portion can be obtained.

  FIG. 5 is a perspective view showing the cable protection guide member 30 in the vicinity of the folded portion. In the drawing, the cable 41 accommodated in the protection guide member 30 is omitted.

  As shown in the figure, the protective guide member 30 is bent at the folded portion by widening the interval of the slits 36. Here, since the end portion 36 a on the curved surface 33 side is rounded in the slit 36, it is possible to prevent stress from concentrating on the tip of the slit 36 when the interval between the slits 36 is widened. For this reason, it can suppress that a crack arises in the edge part 36a of the slit 36, and the durability of the protection guide member 30 can be improved.

  The function of maintaining the cross-sectional shape of the protective guide member 30 is generated by the curved surface 33 where the slit 36 is not provided, the side surface 34 where the slit 36 is provided, and the portion of the dividing surface 35 other than the slit 36. Furthermore, since the curved surface 33 of the protection guide member 30 is curved inward, the bending resistance of the protection guide member 30 with the curved surface 33 as the inner peripheral side is improved. For this reason, the protection guide member 30 can support the weight of the protection guide member 30 and the weight of the cable 41, and can stabilize the shape of the protection guide member 30.

  The width of the gap 37 formed on the dividing surface 35 is gradually narrowed from the straight portion toward the folded portion. For this reason, it is possible to prevent the cable 41 from being detached from the protection guide member 30 even at the portion where the cable 41 is folded together with the protection guide member 30. Further, the curved surface 33 is deformed so as to extend as it goes from the straight portion to the folded portion, and the end of the dividing surface 35 on the gap 37 side is inclined so as to approach the curved surface 33 side. For this reason, even if force acts on the dividing surface 35 from the cable 41, it can suppress that the cable 41 remove | deviates from the protection guide member 30. FIG.

  The cable protection guide member 30 in the twisted portion has a shape obtained by twisting the protection guide member 30 shown in FIG. That is, in the figure, the horizontal positions of the upper and lower portions of the protective guide member 30 are shifted. Also in this case, the same effect as the folded portion can be obtained.

  Next, returning to FIG. 1, a structure for attaching the protective guide member 30 having such a configuration to the XY table 20 and the actuator 25 will be described.

  The protection guide member 30 is disposed with the curved surface 33 facing upward, and the first end 30 a is fixed to the end of the Y-axis table 21. The protection guide member 30 is linearly extended along the Y-axis direction to the first folding position 31 beyond the intersection 26 between the Y-axis table 21 and the X-axis table 22.

  The protective guide member 30 is folded at the first folding position 31 by bending the curved surface 33 toward the inner circumferential side, that is, toward the X-axis table 22 side so as to widen the interval between the slits 36 on the outer circumferential side. The folded protection guide member 30 is extended to the intersection 26 along the Y-axis direction. At this time, when the distance between the first folding position 31 and the intersecting portion 26 is long, the protective guide member 30 is extended linearly, and when the distance between the first folding position 31 and the intersecting portion 26 is short. That is, the protective guide member 30 is extended in a curved shape.

  The protection guide member 30 is twisted at the intersecting portion 26 so as to be directed in the X-axis direction with the curved surface 33 as the inner peripheral side. At this time, the protective guide member 30 is bent so as to widen the interval between the slits 36 on the outer peripheral side, and the extending direction is changed from the Y-axis direction to the X-axis direction. The intermediate portion 30 b of the protection guide member 30 is fixed to the intersecting portion 26 near the end of the X-axis table 22. For this reason, the movement of the intermediate portion 30b of the protection guide member 30 along the X-axis direction is restricted at the intersection 26. The intermediate portion 30 b is moved in the Y axis direction together with the X axis table 22 as the Y axis table 21 is driven.

  The protection guide member 30 extends linearly along the X-axis direction from the intermediate portion 30b to the second folding position 32 beyond the actuator 25. The protection guide member 30 is folded at the second folding position 32 by bending the curved surface 33 toward the inner circumference side, that is, toward the actuator 25 side so as to widen the gap between the slits 36 on the outer circumference side. The folded protection guide member 30 is extended to the actuator 25 along the X-axis direction. The second end 30 c of the protection guide member 30 is fixed to the actuator 25. For this reason, the second end portion 30 c is moved in the X-axis direction together with the actuator 25 as the X-axis table 22 is driven.

  Next, a mode in which the cable 41 is guided by the cable protection guide member 30 when the XY table 20 is driven will be described with reference to FIG.

  When the X-axis table 22 and the actuator 25 move in the direction of the arrow Y1, the first folding position 31 moves in the direction of the arrow Y1, and the cable 41 is sent out together with the protective guide member 30. On the other hand, when the actuator 25 moves in the direction of the arrow X1, the second folding position 32 moves in the direction of the arrow X1, and the cable 41 is sent out together with the protection guide member 30. Therefore, the protective guide member 30 can guide the cable 41 along the Y-axis direction and the X-axis direction. Here, since the intermediate portion 30b of the protective guide member 30 is fixed to the intersecting portion 26, the movement of the intermediate portion 30b along the X-axis direction is restricted, and the twisted portion of the protective guide member 30 is swung. Can be suppressed.

  The embodiment described above has the following advantages.

  A cable protection guide member 30 is provided along the Y-axis table 21 and the X-axis table 22, and the second end 30 c of the protection guide member 30 is attached to the actuator 25. Here, since the protection guide member 30 is integrally formed in a long shape with resin, the protection guide member 30 itself has a configuration as compared with the protection guide member that is assembled by connecting a number of conventional link members and the like. It can be simplified and the assembly work can be omitted.

  The protective guide member 30 has a rectangular shape with a hollow cross section perpendicular to the longitudinal direction, and the protective guide member 30 has a longitudinal direction in which three surfaces (two side surfaces 34 and a divided surface 35) are cut, leaving the curved surface 33. Slits 36 perpendicular to are provided at predetermined intervals in the longitudinal direction. For this reason, the protection guide member 30 can be bent or twisted so that the curved surface 33 where the slits 36 are not provided is on the inner peripheral side and the interval between the slits 36 on the outer peripheral side is widened. At this time, the function of maintaining the cross-sectional shape of the protective guide member 30 is generated by the curved surface 33 where the slit 36 is not provided and the portions other than the three slits 36 where the slit 36 is provided. Therefore, the deformation of the protection guide member 30 can be suppressed and the shape can be stabilized with respect to the weight of the protection guide member 30 and the weight of the cable 41 accommodated in the protection guide member 30.

  The protection guide member 30 is extended along the Y-axis direction to the first folding position 31 beyond the intersection 26 with the X-axis direction, and folded at the first folding position 31 with the curved surface 33 as the inner peripheral side. Thus, it extends to the intersection 26 along the Y-axis direction. In other words, the protective guide member 30 can be folded back by bending the curved surface 33 not provided with the slit 36 to the inner peripheral side and widening the interval between the slits 36 on the outer peripheral side.

  The protection guide member 30 is twisted so as to extend in the X-axis direction with the curved surface 33 at the inner peripheral side at the intersection 26, and is extended along the X-axis direction and attached to the actuator 25. In other words, the protective guide member 30 can be directed from the Y-axis direction to the X-axis direction by twisting the curved surface 33 on the inner peripheral side and widening the gap between the outer peripheral slits 36.

  When the actuator 25 moves along the Y-axis direction, the first folding position 31 moves along the Y-axis direction and the protective guide member 30 is sent out, so that the cable 41 is guided by the protective guide member 30. can do. As a result, the attachment structure 10 for attaching the protective guide member 30 provided along two directions intersecting each other to the actuator 25 can be realized by the protective guide member 30 integrally formed in a long shape. The mounting man-hour can be reduced.

  That is, by adopting the structure of the protective guide member 30 and the mounting structure 10 (bending and twisting with the curved surface 33 not provided with the slit 36 on the inner peripheral side), even one protective guide member 30 can be used. It can be arranged in two intersecting directions. For this reason, both bending with respect to the movement of the actuator 25 along the Y-axis direction and twisting with respect to the direction change of the protective guide member 30 from the Y-axis direction to the X-axis direction can be achieved.

  The protective guide member 30 is twisted so as to be directed in the X-axis direction, and then is extended along the X-axis direction to the second folding position 32 beyond the actuator 25, and the curved surface 33 is formed at the second folding position 32. Folded on the inner circumference side. Therefore, when the actuator 25 moves along the X-axis direction, the second folding position 32 moves along the X-axis direction and the protection guide member 30 is sent out, so that the cable protection guide member 30 causes the cable to move. 41 can be guided. As a result, even when the actuator 25 moves in two directions, the Y-axis direction and the X-axis direction, the cable 41 can be protected and guided by the protective guide member 30 that is integrally formed in a long shape. .

  Since the protection guide member 30 is restricted from moving along the X-axis direction at the intersecting portion 26, the portion twisted so as to go in the X-axis direction with the curved surface 33 on the inner peripheral side swings. This can be suppressed. Even if the movement of the protective guide member 30 along the X-axis direction is restricted at the intersection 26, the movement of the first folding position 31 and the second folding position 32 is not hindered. Therefore, the protective guide member 30 does not hinder the guide of the cable 41 accompanying the movement of the actuator 25.

  In the cross section perpendicular to the longitudinal direction of the protective guide member 30, the curved surface 33 is curved inward, so that the rigidity with respect to the bending of the protective guide member 30 with the curved surface 33 as the inner peripheral side can be improved. Therefore, the deformation of the protection guide member 30 can be effectively suppressed with respect to the weight of the protection guide member 30 and the weight of the cable 41 accommodated in the protection guide member 30. As a result, the shape of the protection guide member 30 can be further stabilized.

  Since the split surface 35 facing the curved surface 33 in the protective guide member 30 is divided into two along the longitudinal direction of the protective guide member 30, the cable 41 is easily inserted into the protective guide member 30 from the crack. be able to.

  When the protective guide member 30 is bent with the curved surface 33 on the inner peripheral side, the curved surface 33 is deformed so as to be extended. For this reason, the two side surfaces 34 connected to the curved surface 33 are inclined so as to fall to the curved surface 33 side, and a divided portion (a portion of the gap 37) of the divided surface 35 connected to the two side surfaces 34 is curved. It will approach the surface 33 side. For this reason, the crack of the protection guide member 30 is closed, and the cable 41 can be prevented from protruding from the protection guide member 30. Therefore, the cable 41 accommodated in the protection guide member 30 can be firmly held even in the portion where the protection guide member 30 is bent.

  In the slit 36, since the end portion 36a on the curved surface 33 side is rounded, the end portion 36a of the slit 36 is bent when the curved surface 33 is bent so that the interval between the outer peripheral side slits 36 is widened with the curved surface 33 as the inner peripheral side. It is possible to suppress cracks from occurring. As a result, the durability of the protective guide member 30 can be improved.

  In addition, the said embodiment can also be deform | transformed and implemented as follows. About the same member as the said embodiment, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  If the drive of the Y-axis table 21 and the drive of the X-axis table 22 are not hindered, the XY table 20 may be covered with a cover or the like. That is, the cable protection guide member 30 can be provided inside a cover or the like.

  -It is also possible to omit rounding the end 36a of the slit 36.

  In the above embodiment, the slit 36 is cut from the dividing surface 35 to the vicinity of the curved surface 33. However, if the curvature radius of the folded portion or the twisted portion of the protective guide member 30 is large, the slit 36 cuts to the curved surface 33 side. The length may be shortened.

  As shown in FIG. 7, a cable protection guide member 130 in which the facing surface 135 that faces the curved surface 33 is not divided may be employed. In this case, the cable 41 is inserted into the inside from the opening at the end of the protective guide member 130. According to such a protection guide member 130, it is possible to reliably prevent the cable 41 from being detached from the protection guide member 130.

  In the cable protection guide members 30 and 130, the curved surface 33 can be formed into a flat surface.

  In the above embodiment, the intermediate portion 30b of the protective guide member 30 is fixed to the intersecting portion 26 of the X-axis table 22, but the intermediate portion 30b can be freely movable. Even in this case, the cable 41 can be guided in the Y-axis direction and the X-axis direction due to the shape stability of the protective guide member 30 itself.

  As shown in FIG. 8, the protective guide member 30 can be attached to the front side of the X-axis table 22 in the Y-axis direction. In this case, the intermediate portion 30b of the protection guide member 30 is fixed to the front side in the Y-axis direction at the intersecting portion 26 of the X-axis table 22, and the second end portion 30c of the protection guide member 30 is What is necessary is just to fix to the near side of an axial direction. Even with such a configuration, the cable 41 can be guided by the protective guide member 30 when the XY table 20 is driven. Further, in the Y-axis table 21, the protective guide member 30 can be attached to the front side in the X-axis direction.

  In the above embodiment, the actuator 25 can be moved in the X-axis direction by the X-axis table 22, but as shown in FIG. 9, the actuator 25 is fixed near the end of the X-axis table 22. You can also In this case, it is not necessary to provide the second folding position 32 on the protection guide member 30, and the second end 30 c of the protection guide member 30 may be fixed near the end of the X-axis table 22.
