Both ends of the guide shaft 12 are fixed to the support bracket 16.

  FIG. 4 is an enlarged cross-sectional view showing a main part of the rotation mechanism 6 in the state of FIG. FIG. 5 is a plan view of FIG. 4, and FIG. 6 (a) is a cross-sectional view taken along the line AA of FIG. 4 and 5, the drive member 13 is formed in a rectangular parallelepiped shape, and the lower surface thereof is disposed at a predetermined interval from the upper surface 2 a of the substrate 2 and is close to the upper surface of the rotary slider 14. Are arranged to be. Further, the center line Z extending in the longitudinal direction of the drive member 13 is orthogonal to the axes X and Y in the plan view of FIG. 5 and is disposed at the same height as the axes X and Y in the cross-sectional view of FIG. Yes. Female screw holes 13a and insertion holes 13b are formed at both ends of the drive member 13 in the center line Z direction. The male screw portion 11b of the drive shaft 11 is screwed into the female screw hole 13a. The guide shaft 12 is inserted through the insertion hole 13b, and the drive member 13 is attached to the guide shaft 12 so as to be relatively movable in the axis Y direction. A long hole 13 c extending in the center line Z direction is formed at the center of the drive member 13.

  In FIG. 4, the rotary slider 14 is formed of a strip plate member and is disposed between the substrate 2 and the drive member 13. The lower surface of the rotating slider 14 is a sliding surface 14 a that rotates while sliding on the upper surface 2 a of the substrate 2. In FIG. 1, the base end portion of the rotary slider 14 is rotatably attached to the rotary shaft 9. The tip of the rotary slider 14 is connected to a rotary coupling conductor 5 (conductor body 5a) disposed on the lower surface 2b of the substrate 2 via a pin member 17 inserted into a through hole 2c formed in the substrate 2. Connected to the tip. As shown in FIG. 2, the through hole 2c is formed in an arc shape having a radius r3 (> r2) with the center point C as the center.

  In the state of FIG. 1, the rotary slider 14 is at a position immediately below the drive member 13 and at a position orthogonal to the drive shaft 11 and the guide shaft 12, and the right direction in FIG. Or it rotates to the left. Further, the distal end portions of the rotary sliders 14 of the first distribution phase shifter A1 and the second distribution phase shifter A2 are respectively connected to both ends of the connection member 18 via the pin members 17. . Thus, when the rotary slider 14 of the first distribution phase shifter A1 is rotated around the center point C, the rotary coupling conductor 5 of the first distribution phase shifter A1 rotates via the pin member 17. At the same time, the rotary slider 14 and the rotary coupling conductor 5 of the second distribution phase shifter A2 are rotated in conjunction with each other via the connecting member 18.

  4 and 5, the engagement pin 15 is formed in a columnar shape, and a lower end portion (one end portion) thereof is fixed to an upper surface of a substantially central portion in the longitudinal direction of the rotary slider 14. The outer peripheral surface of the upper end portion (the other end portion) of the engagement pin 15 is an engagement portion 15 a that is engaged with the drive member 13. As shown in FIG. 4, the engaging portion 15 a is a surface that includes the axis X of the drive shaft 11 and is displaced from the orthogonal surface S that is a surface orthogonal to the substrate 2 toward the guide shaft 12. The drive member 13 is inserted into the long hole 13 c so as to engage with the drive member 13.

  Thus, when the drive shaft 11 is rotationally driven to rotate the male screw portion 11b, the drive member 13 is linearly moved in the axis X direction relative to the male screw portion 11b while being guided by the guide shaft 12. At this time, the engaging pin 15 moves relative to the driving member 13 in the direction of the center line Z along the long hole 13 c, so that the rotary slider 14 slides on the upper surface 2 a of the substrate 2 together with the engaging pin 15. It rotates around the center point C while moving. Then, by rotating the rotary slider 14, the rotary coupling conductor 5 disposed on the lower surface 2 b of the substrate 2 rotates about the center point C.

As described above, according to the distribution phase shifter according to the first embodiment of the present invention, the rotary coupling conductor 5 is moved via the engagement pin 15 and the rotary slider 14 by moving the drive member 13 in the direction of the axis X. Can be rotated. Thereby, the rotation coupling conductor 5 can be rotated with a simple configuration without using a gear.
Further, since the engaging portion 15a of the engaging pin 15 is a surface including the axis line X of the drive shaft 11 and deviated from the orthogonal surface S orthogonal to the substrate 2, the engaging portion 15a and the drive shaft 11 can be avoided from being arranged on the orthogonal plane S. Therefore, the rotation mechanism 6 can be compactly arranged in the direction orthogonal to the substrate 2.

Further, since the movement of the drive member 13 is guided by the guide shaft 12, the drive member 13 can be smoothly moved in the direction of the axis X even when the engagement pin 15 is displaced from the orthogonal plane S.
Further, since the rotary slider 14 is arranged so as to slide on the upper surface 2 a of the substrate 2, the rotation mechanism 6 can be arranged more compactly in a direction orthogonal to the substrate 2.

Further, since the lower end portion of the engagement pin 15 is fixed to the rotary slider 14 and the upper end portion of the engagement pin 15 is engaged with the drive member 13, the engagement is performed as shown in FIG. Compared with the case where the upper end portion of the pin 15 is attached to the drive member 13 and the lower end portion is engaged with the rotary slider 14, the vertical distance L1 to the axis X of the drive shaft 11 can be shortened (FIG. 6 (a)). As a result, the magnitude of the moment generated in the drive member 13 can be reduced with the distance L1 as the length of the arm.
Specifically, in FIG. 6A, when the driving member 13 moves to the left along the axis X, for example, the lower right portion of the long hole 13c pushes against the engaging portion 15a of the engaging pin 15. Hit. At this time, when the frictional resistance between the sliding surface 14a and the upper surface 2a of the substrate 2 is large, the driving member 13 is rotated counterclockwise in FIG. 6A with the intersection 13d of the driving member 13 with the axis X as a fulcrum. There may be moments that try to rotate in the direction. In the present embodiment, since the distance L1 is short, the magnitude of the moment can be reduced even if the moment is generated. Therefore, the drive member 13 can be smoothly moved in the direction of the axis X of the drive shaft 11.

Further, since the drive member 13 is disposed close to the rotary slider 14, as shown in FIG. 6A, the sliding surface of the rotary slider 14 from the engaging portion 15 a of the engaging pin 15. The vertical distance L2 up to 14a can be shortened. Thereby, the magnitude | size of the moment which generate | occur | produces in the rotary slider 14 can be reduced by making this distance L2 into the length of an arm.
Specifically, in FIG. 6A, when the drive member 13 moves to the left along the axis X, for example, the lower right portion of the long hole 13c is engaged with the engaging portion 15a of the engaging pin 15 as described above. Pressed against. At this time, when the frictional resistance between the sliding surface 14a and the upper surface 2a of the substrate 2 is large, the rotary slider 14 is turned counterclockwise in FIG. 6A with the left edge 14a1 of the sliding surface 14a as a fulcrum. There may be moments that try to rotate in the turning direction. In this embodiment, since the distance L2 is short, the magnitude of the moment can be reduced even if the moment is generated. Therefore, the rotary slider 14 can be smoothly rotated following the movement of the drive member 13.

  Further, since the output side conductor 3, the input side conductor 4, and the rotary coupling conductor 5 are disposed on the lower surface 2b of the substrate 2, and the rotation mechanism 6 is disposed on the upper surface 2a of the substrate 2, the output side conductor 3, the input side conductor The rotating mechanism 6 can be prevented from adversely affecting the 4 and the rotary coupling conductor 5.

It is constituted by. Each engagement piece portion 25 b is engaged with each recess portion 23 a of the drive member 23.

As a result, when the drive member 23 is linearly moved in the axis X direction, the engagement piece portion 25b moves relative to the drive member 23 along the recess portion 23a in the center line Z direction, thereby rotating and sliding. The child 14 can be rotated around the center point C. At that time, the engaging piece portion 25b rotates about the axis W with respect to the rotary slider 14 via the rotating plate portion 25a.
