Upon receiving the control signal, the electric unit 50 drives the motor 52 and rotates the driven body 353 via the drive unit 56. As the driven body 353 rotates, the connection member 375 (see FIG. 1) moves, and as a result, the beam tilt angle of the antenna 1 (see FIG. 1) is changed. That is, the electric unit 50 changes the beam / tilt angle of the antenna 1 electrically.

In the illustrated example, the unit main body 51 has an integrated structure in which a motor 52 and a potentiometer 53 are accommodated. That is, the electric unit 50 has a modularized configuration.
Note that a motor 52 and a potentiometer 53 are arranged in the vertical direction inside the unit main body 51 in the illustrated example. In other words, the motor 52 and the potentiometer 53 are arranged in the vertical direction, so that the cross-sectional area of the unit main body 51 is suppressed, and as a result, the area occupied by the electric unit 50 in the lower lid 115 is suppressed.

<Upper end of electric unit 50>
9A to 9D are explanatory views of the upper end portion of the electric unit 50. FIG. More specifically, FIG. 9A is a perspective view around the drive unit 56 of the electric unit 50, FIG. 9B is a side view of the drive unit 56, and FIG. 9C is viewed from above. FIG. 9D is a front view of the drive unit 56, and FIG. 9D is a perspective view around the unit terminal 55 of the electric unit 50.

Next, the upper end portion of the electric unit 50 will be described with reference to FIGS. 9 (a) to 9 (d). The upper end portion of the electric unit 50 is a tip end portion in the insertion direction of the electric unit 50 from the lower side to the upper side.
First, as shown in FIG. 9A, a drive unit 56 is provided at the upper end of the electric unit 50. As shown in FIG. 9B, the drive unit 56 has a substantially cylindrical shape, and external teeth 561 that mesh with the internal teeth 355 (see FIG. 5A) of the driven body 353 are formed on the outer peripheral surface. Yes. Further, as shown in FIG. 9C, a chamfer 563 is formed on the upper (tip side) end of the external tooth 561.

The drive unit 56 enters the opening 354 (see FIG. 5A) of the driven body 353, thereby meshing with the driven body 353 and transmitting the driving force of the motor 52. In other words, the drive unit 56 and the driven body 353 function as a transmission unit that transmits the output of the motor 52.
More specifically, when the electric unit 50 is inserted, even when the rotation angle between the inner teeth 355 and the outer teeth 561 is deviated, the driving unit 56 is operated in the operation in which the driving unit 56 enters the opening 354. The 56 external teeth 561 push the trapezoidal serration 357 (see FIG. 5A) of the internal teeth 355. Along with this, the driven body 353 passively rotates, and the angles of the internal teeth 355 and the external teeth 561 are matched. As a result, the inner teeth 355 and the outer teeth 561 mesh with each other. In other words, the trapezoidal serration 357 adjusts the rotation angle between the inner teeth 355 and the outer teeth 561. In particular, by setting the inclination angle α in the trapezoidal serration 357 to an appropriate value as described above, the drive unit 56 can enter the opening 354 (see FIG. 5A) of the driven body 353 more smoothly. I can do it.

Now, as shown in FIG. 9D, a unit terminal 55 is provided at the upper end of the electric unit 50. The unit terminal 55 is configured by an elastically deformable contact (so-called spring contact).
The unit terminal 55 transmits a control signal for the electric unit 50 to and from the substrate body 391 by contacting the substrate body 391 (see FIG. 7A) of the casing 30.
Further, the unit terminal 55 is elastically deformed, so that the electrical connection with the substrate body 391 is maintained even when the vertical position of the electric unit 50 is changed.

Here, in the present embodiment, when the electric unit 50 is inserted into the main body 31 (see FIG. 3) of the casing 30 (see FIG. 3), the drive unit 56 engages (fits) the driven body 353. In addition, the unit terminal 55 is electrically connected to the casing terminal 39. That is, the electric unit 50 is mechanically and electrically connected to the casing 30 by being inserted into the casing 30.
In the present embodiment, the position of the unit terminal 55 is the upper end of the electric unit 50. However, this position is not limited to the upper end, but may be the upper side surface, the middle of the electric unit 50 in the vertical direction, or the like. May be.

Now, according to the present embodiment, for example, even when the motor 52 included in the electric unit 50 fails after the antenna 1 (see FIG. 1) is installed, it is possible to cope with the failure without stopping the antenna 1. To explain further, the failed electric unit 50 can be pulled out and replaced with a new electric unit 50 while the antenna 1 is operating without removing the entire antenna 1. Furthermore, the motor 52 can be replaced without disassembling the antenna 1.

<Fixed aspect of electric unit 50>
FIG. 10 is an explanatory diagram of a fixing mode of the electric unit 50.
Next, an aspect of fixing the electric unit 50 to the casing 30 will be described with reference to FIG.
As shown in FIG. 10, the electric unit 50 is fixed to the casing 30 via the claw portion 323 of the casing 30 and the bolt 61. More specifically, the flange 58 of the electric unit 50 is pressed by the claw portion 323 and the bolt 61. As a result, the electric unit 50 is fixed (restricted in the vertical direction).

Next, the operation from when the electric unit 50 is inserted into the casing 30 until it is fixed will be described.
First, when the electric unit 50 is inserted, the claw portion 323 retreats from the passage path of the electric unit 50 while being elastically deformed. When the electric unit 50 moves in the insertion direction and the flange 58 passes, the claw portion 323 is engaged with the flange 58. Thus, for example, even when the operator accidentally releases his / her hand, the electric unit 50 is prevented from coming out (falling) out of the casing 30. If it adds, the nail | claw part 323 can be regarded as a fall suppression mechanism which suppresses that the electric unit 50 falls.

In this state, the bolt 61 is fixed to the through hole 59 formed in the flange 58. In other words, after the electric unit 50 is temporarily fixed (simple lock) by the claw portion 323, the fixing is performed in two stages by further fixing with the bolt 61.
Here, when the electric unit 50 is temporarily fixed in the first stage of the two stages, for example, the operator can release his / her hand from the electric unit 50, and the operator can tighten the bolt 61. Can be easy. In addition, when the electric unit 50 receives external force by being fixed with the bolt 61 in the second stage of the two stages, the unit terminal 55 (see FIG. 9D) and the casing terminal 39 (see FIG. 9). Electrical connection with (see (d)) is ensured.

Now, in the example shown in the figure, the claw portion 323 and the bolt 61 are respectively disposed on both ends in the longitudinal direction of the flange 58 formed in a substantially elliptical shape. With this arrangement, rotation of the electric unit 50 inserted into the casing 30 is suppressed. The illustrated flange 58 includes a notch 581 on the outer periphery. This notch 581 is dimensioned to receive the claw portion 323. The notch 581 also prevents the electric unit 50 from rotating.

Further, as shown in FIG. 10, in a state where the electric unit 50 is fixed, the flange 58 and the handle 57 are exposed to the outside of the casing 30. More specifically, the handle 57 protrudes to the outside. This makes it easier for an operator to grip the handle 57 when the electric unit 50 is pulled out.

Furthermore, in the illustrated example, in a state where the electric unit 50 is fixed, the drive unit 56 (see FIG. 9D) and the unit terminal 55 (see FIG. 9D) above the insertion hole 311 of the casing 30. )) Is arranged. Therefore, the drive unit 56 and the unit terminal 55 are suppressed from being affected by water droplets or dust that can enter from between the insertion hole 311 and the electric unit 50. Further, as described above, the electric unit 50 has a waterproof and dustproof structure provided with a gasket 54 (see FIG. 8) and the like. Therefore, the gasket 54 or the like suppresses the components inside the electric unit 50 from being affected by water droplets or dust.

<Manual unit 70>
FIG. 11 is an explanatory diagram of the manual unit 70.
Next, the manual unit 70 will be described with reference to FIG.
As shown in FIG. 11, a manual unit 70 which is an example of a rotation mechanism and a phase shift control device includes a cylindrical portion 71 and a support plate 73 (a plurality of support units 73 provided along the axial direction of the cylindrical portion 71 and supporting the cylindrical portion 71. A first support plate 731, a second support plate 733, a third support plate 735), a fixed plate 74 fixed to the lower surface of the first support plate 731, a handle portion (knob) 75 operated by an operator, A shaft portion 76 provided through the cylindrical portion 71 and having one end connected to the handle portion 75 and a drive portion (external gear) 77 provided at the other end of the shaft portion 76 are provided. In the illustrated example, the manual unit 70 is formed of a resin such as polyoxymethylene (POM), but may be formed of a metal such as aluminum.

The cylindrical portion 71 has a central axis arranged along the vertical direction. The cylindrical portion 71 in the illustrated example is provided with both ends sandwiched between the first support plate 731 and the third support plate 735.
The support plate 73 (the first support plate 731, the second support plate 733, and the third support plate 735) is a substantially elliptical plate member. Further, through holes 7310, 7330, and 7350 are formed in each of the support plates 73, and the cylindrical portion 71 is inserted and fixed with an adhesive or the like.

The support plate 73 has a shape corresponding to the unit support portion 313 (see FIG. 3) of the casing 30. More specifically, the outer shape of the support plate 73 is a dimension corresponding to the outer shape of the unit main body 51 of the electric unit 50 (see FIG. 8). Specifically, for example, the length in the longitudinal direction of the support plate 73 and the length in the longitudinal direction in the cross section of the unit main body 51 coincide with each other in the length L1 (see FIG. 8). Further, as described above, the support unit 73 and the cylindrical portion 71 are fixed, so that the manual unit 70 can be smoothly inserted into the unit support portion 313 of the casing 30.

In this way, the electric unit 50 and the manual unit 70 can be exchanged by forming the portions inserted into the casing 30 in the electric unit 50 and the manual unit 70 with corresponding dimensions (same dimensions).
The third support plate 735 includes a mold hole 736 provided coaxially with the through hole 7350 on the upper surface (details will be described later).

The through-hole 740 is formed in the fixing plate 74, and the cylindrical portion 71 is inserted. The fixed plate 74 is a substantially oval plate member. The fixed plate 74 has a size larger than that of the support plate 73. The fixing plate 74 includes a claw portion 732 protruding from the lower surface, a notch 734 formed on the outer periphery, and a through hole 737 provided penetrating in the thickness direction (vertical direction) of the fixing plate 74. Prepare.

The handle portion 75 is a substantially cylindrical member and is provided below the fixed plate 74. The handle portion 75 includes an outer circumferential groove 751 formed along the circumferential direction and a recess 753 provided to be separated from each other in the circumferential direction. The recess 753 is a portion that receives the operator's finger, and in the illustrated handle portion 75, three recesses 753 are formed.

The shaft portion 76 is a substantially columnar member. The shaft portion 76 is provided through the cylindrical portion 71, the handle portion 75 is connected to the lower end portion, and the driving portion 77 is connected to the upper end portion. Here, the shaft portion 76 is formed with a longer dimension than the cylindrical portion 71. More specifically, the shaft portion 76 is longer between the handle portion 75 and the drive portion 77 than the length of the cylindrical portion 71 so that the handle portion 75 and the drive portion 77 can move in the vertical direction. Hold at a distance. That is, the shaft portion 76 is configured to have play in the thrust direction with respect to the cylindrical portion 71.
Further, the shaft portion 76 includes an identification portion 761 (see FIG. 12A described later) formed along the outer peripheral surface of the outer end portion. The identification portion 761 is a portion in which an outer peripheral groove formed in the circumferential direction of the shaft portion 76 is colored.

The drive unit 77 is configured in the same manner as the drive unit 56 (see FIG. 9A) of the electric unit 50 described above. Specifically, the drive unit 77 is a substantially cylindrical shape, and external teeth 771 that mesh with the internal teeth 355 of the driven body 353 (see FIG. 5A) are formed on the outer peripheral surface. Further, a chamfer 773 is formed on the upper (tip side) end of the external tooth 771. The handle portion 75 and the drive portion 77 are an example of a manual rotation mechanism.

When the manual unit 70 is inserted into the main body 31 (see FIG. 3) of the casing 30, the drive unit 77 provided at the front end of the manual unit 70 is connected to the driven body 353 (see FIG. 3) of the casing 30. Engage. Then, when the operator rotates the handle portion 75, force is transmitted through the shaft portion 76 and the drive portion 77, and the driven body 353 rotates. As the driven body 353 rotates, the connection member 375 (see FIG. 1) moves, and as a result, the beam tilt angle of the antenna 1 is changed. That is, the manual unit 70 manually changes the beam tilt angle of the antenna 1.

Here, the drive unit 77 enters the opening 354 (see FIG. 5A) of the driven body 353 to be engaged with the driven body 353, and the force received by the handle unit 75 is applied to the driven body 353. introduce. In other words, the drive unit 77 and the driven body 353 function as a transmission unit that transmits the force received from the worker.
More specifically, even when the rotation angle between the internal teeth 355 (see FIG. 5A) and the external teeth 771 is shifted, as in the drive unit 56 (see FIG. 9A) described above. When the driving unit 77 enters the opening 354, the driven body 353 passively rotates and the inner teeth 355 and the outer teeth 771 mesh.

<Lock mechanism>
12A and 12B are explanatory diagrams of a lock mechanism in the manual unit 70. FIG. More specifically, FIG. 12A is a diagram illustrating the manual unit 70 in the rotation suppression state, and FIG. 12B is a diagram illustrating the manual unit 70 in the suppression release state.
Next, the locking mechanism in the manual unit 70 will be described with reference to FIGS. 12 (a) and 12 (b).

First, the manual unit 70 is in a state in which rotation of the handle portion 75, the shaft portion 76, and the drive portion 77 is suppressed by the operator moving the handle portion 75 in the vertical direction, that is, a rotation suppression state (FIG. 12 ( a) and a state where the rotation suppression is released, that is, the suppression release state (see FIG. 12B) is switched. Therefore, the manual unit 70 can be locked by a simple operation. Further, this lock can suppress unintended rotation of the handle portion 75 and the like.

Here, the rotation suppression state and the suppression release state will be further described.
As shown in FIG. 12A, in the rotation restrained state, the handle portion 75, the shaft portion 76, and the drive portion 77 are in a state of moving downward (a predetermined direction). In this state, the drive unit 77 engages with the third support plate 735, and the rotation of the drive unit 77 is limited by the third support plate 735 (details will be described later). Further, the claw portion (restriction mechanism) 732 of the fixing plate 74 engages with the outer peripheral groove 751 of the handle portion 75, and the claw portion 732 restricts the movement of the handle portion 75 in the vertical direction (details will be described later).

On the other hand, as shown in FIG. 12B, in the suppression release state, the handle portion 75, the shaft portion 76, and the drive portion 77 are moved upward. In this state, the drive unit 77 is separated from the third support plate 735, and the third support plate 735 allows the drive unit 77 to rotate. Further, the claw portion 732 is disengaged from the outer peripheral groove 751 of the handle portion 75, and the claw portion 732 allows the handle portion 75 to move in the vertical direction.

Here, the drive unit 77, the third support plate 735, the fixed plate 74, and the handle unit 75 function as a lock mechanism for the manual unit 70.
Hereinafter, the operations of the driving unit 77 and the third support plate 735, the operations of the claw unit 732 and the handle unit 75 of the fixed plate 74, and the operations of the driving unit 77 and the driven body 353 (see FIG. 5A) will be described in order. To do.

<Operation of Drive Unit 77 and Third Support Plate 735>
13A to 13C are explanatory diagrams of the operation of the drive unit 77 and the third support plate 735. FIG. More specifically, FIG. 13A is a perspective view of the third support plate 735 as viewed from above, and FIG. 13B is a view showing the drive unit 77 and the third support plate 735 in a rotation-suppressed state. FIG. 13C is a diagram showing the drive unit 77 and the third support plate 735 in the suppression release state.

Next, operations of the drive unit 77 and the third support plate 735 will be described with reference to FIGS.
First, as shown in FIG. 13A, a mold hole 736, which is an example of a recess, is formed in the third support plate 735, which is an example of a restriction mechanism. The inner peripheral surface of the mold hole 736 has a shape that meshes with the external teeth 771 (see FIG. 13B) of the drive unit 77. In other words, inner teeth that mesh with the outer teeth 771 of the drive unit 77 are formed on the inner peripheral surface of the mold hole 736. In the illustrated example, eight convex portions (eight concave portions) are formed along the inner periphery of the mold hole 736. The mold hole 736 has an outer diameter larger than that of the through hole 7350, and the third support plate 735 includes a to-be-abutted portion 738 that is a step between the mold hole 736 and the through hole 7350.

Next, as shown in FIG. 13B, in the rotation restricted state, the drive unit 77 moved downward is in a state of being stuck in the mold hole 736. As a result, the rotation of the drive unit 77 is limited. The drive unit 77 moving downward is abutted against the abutted portion 738 of the third support plate 735 (see FIG. 13A). This suppresses the drive unit 77 from being pulled downward.
On the other hand, as shown in FIG. 13C, in the suppression release state, the drive unit 77 that has moved upward does not mesh with the mold hole 736. As a result, the rotation of the drive unit 77 is not limited.

<Operation of Claw 732 and Handle 75>
14A to 14C are explanatory views of the operation of the claw portion 732 and the handle portion 75. FIG. More specifically, FIG. 14A is a side view of the claw portion 732, FIG. 14B is a view showing the claw portion 732 and the handle portion 75 in a rotation-suppressed state, and FIG. It is a figure which shows the nail | claw part 732 and the handle | steering-wheel part 75 of the suppression cancellation | release state.

Next, operations of the claw portion 732 and the handle portion 75 will be described with reference to FIGS. 14 (a) to 14 (c).
First, as shown in FIG. 14A, the fixing plate 74 includes a claw portion 732 on the outer periphery of the through hole 740. The claw portion 732 includes a top portion 7321 that protrudes toward the center of the through hole 740.

Next, as shown in FIG. 14B, in the rotation restricted state, the claw portion 732 engages with the outer circumferential groove 751 of the handle portion 75. When further described, the top portion 7321 of the claw portion 732 has the outer circumferential groove. 751 enters the state. As a result, the movement of the handle portion 75 in the vertical direction is restricted, and the unintentional release of the rotation restricted state is suppressed.
Specifically, in order for the handle portion 75 to move in the vertical direction, it is necessary to elastically deform the claw portion 732 until the top portion 7321 moves to the outside of the outer peripheral groove 751. Thus, the force to be applied for the movement of the handle portion 75 is increased by the amount of elastic deformation of the claw portion 732.

As shown in FIG. 14B, in the rotation restricted state, the identification unit 761 is visible from the outside as the handle unit 75 moves downward. The operator can recognize that the handle portion 75 is in a rotation restricted state, that is, a locked state, by the operator visually recognizing the identification portion 761.

On the other hand, as shown in FIG. 14C, the claw portion 732 does not engage with the outer peripheral groove 751 of the handle portion 75 in the suppression release state. More specifically, the top portion 7321 of the claw portion 732 is in a state existing outside the outer circumferential groove 751. As a result, the movement of the handle portion 75 is not limited. In the suppression release state, the identification unit 761 is not visible from the outside.

<Operation of Driving Unit 77 and Driven Body 353>
FIG. 15 is an explanatory diagram of the operation of the drive unit 77 and the driven body 353.
Next, operations of the drive unit 77 and the driven body 353 will be described with reference to FIG. In FIG. 15, the drive unit 77 in the rotation restricted state is indicated by a solid line, and the drive unit 77 in the suppression release state is indicated by a broken line.

As described above, the drive unit 77 moves in the vertical direction by switching between the rotation restriction state and the suppression release state. Here, as shown in FIG. 15, the engagement of the drive unit 77 and the driven body 353 is maintained in both the rotation restricted state and the suppression release state.
More specifically, even in the rotation restricted state, the external teeth 771 of the drive unit 77 and the internal teeth 355 of the driven body 353 mesh (see arrow E1 in the figure). In other words, in the rotation restricted state, the chamfer 773 of the drive unit 77 and the trapezoidal serration 357 are not at the same position in the vertical direction.

Here, in the rotation restricted state, that is, in a state where the drive unit 77 is fitted in the mold hole 736, the external teeth 771 of the drive unit 77 and the internal teeth 355 of the driven body 353 mesh with each other, thereby The rotation of the driven body 353 is also suppressed through 77. By suppressing the rotation of the driven body 353, the movement of the connecting member 375 (see FIG. 1) connected to the driven body 353 is limited, and as a result, the beam of the antenna 1 (FIG. 1) is restricted. The tilt angle shift is suppressed.

<Fixed aspect of manual unit 70>
FIG. 16 is an explanatory diagram of a fixing mode of the manual unit 70.
Next, a mode in which the manual unit 70 is fixed to the casing 30 will be described with reference to FIG.
The manual unit 70 is fixed in the same manner as the electric unit 50 using FIG. Specifically, as shown in FIG. 16, the fixing plate 74 of the manual unit 70 is pressed by the claw portion 323 and the bolt 61, so that the vertical direction of the manual unit 70 is fixed (the movement in the vertical direction is limited). It will be in the state.

When the manual unit 70 is inserted and fixed in the casing 30, the claw portion 323 is retracted from the passage path of the manual unit 70 while being elastically deformed, and then the claw portion 323 is engaged with the fixing plate 74. . In this state, the bolt 61 is fixed to the through hole 737 of the fixing plate 74. In other words, the claw portion 323 and the bolt 61 are fixed in two stages.

Further, as shown in FIG. 16, in a state where the manual unit 70 is fixed, the fixing plate 74 and the handle portion 75 are exposed (projected) to the outside of the casing 30. This makes it easier for an operator to grip the fixed plate 74 and the handle portion 75 when the manual unit 70 is pulled out.

Here, the colors of the electric unit 50 and the manual unit 70 will be described with reference to FIGS. 10 and 16.
Although not described above, the electric unit 50 and the manual unit 70 are formed in different colors. For example, the flange 58 and the handle 57 that are exposed to the outside in the electric unit 50 inserted into the casing 30 are formed in black. On the other hand, the fixed plate 74 and the handle portion 75 which are exposed to the outside in the manual unit 70 inserted into the casing 30 are formed in white.
In this way, by forming the electric unit 50 and the manual unit 70 in different colors, it is possible to identify which is inserted into the casing 30 from the outside.

<Modification>
In the above description, the electric unit 50 and the manual unit 70 are exchanged. However, the electric units 50 or the manual units 70 may be exchanged.
In the case of a usage pattern in which only the manual unit 70 is inserted into the casing 30, the casing 30 may not be provided with the casing terminal 39. In other words, by switching between a configuration in which the casing terminal 39 is provided and a configuration in which the casing terminal 39 is not provided, a production line for the casing 30 into which the manual unit 70 and the electric unit 50 (or only the electric unit 50) can be inserted, and only the manual unit 70 are inserted. The production line of the casing 30 to be used can be shared.

Further, when replacing the electric unit 50 with another electric unit 50, the manual unit 70 may be temporarily used. Specifically, the manual unit 70 is inserted into the casing 30 after the electric unit 50 that is already mounted is pulled out. Then, the handle unit 75 of the manual unit 70 is operated to manually set the rotating body 35 (or the beam / tilt angle) to a predetermined angle (for example, zero point), and then the manual unit 70 is pulled out to perform another electric operation. The unit 50 may be inserted. In other words, the manual unit 70 may be used as a jig.

In the above description, the drive units 56 and 77 are provided at the tips of the electric unit 50 and the manual unit 70, but the present invention is not limited to this. As long as the electric unit 50 and the manual unit 70 are inserted into the casing 30, the electric unit 50 and the manual unit 70 may be provided at any position as long as they engage with the driven body 353.

In the above description, the electric unit 50 and the manual unit 70 are fixed by the claw portion 323 and the bolt 61. However, the present invention is not limited to this. The electric unit 50 and the manual unit 70 only need to be able to restrict movement in the vertical direction. For example, the electric unit 50 and the manual unit 70 may be fixed by any one of the claw portion 323 and the bolt 61. Instead of the bolt 61, a spring (not shown) that urges the electric unit 50 and the manual unit 70 upward may be used.

In the above description, the configuration in which the claw portion 732 of the fixing plate 74 is applied to the outer peripheral groove 751 of the handle portion 75 is described, but the present invention is not limited to this. If the movement of the handle portion 75 in the vertical direction can be restricted, other configurations such as a mechanism for restricting the movement while the claw portion 732 of the fixing plate 74 engages with the lower end surface of the handle portion 75 may be used.

In the above description, it has been described that the mold hole 736 has eight protrusions on the inner peripheral surface. However, if the shape changes in accordance with the angle with respect to the center of the hole, that is, a shape other than a circle. Good. As described above, by providing a plurality of protrusions having the same configuration in the circumferential direction, the amount of rotation of the drive unit 77 before the drive unit 77 is fitted (fitted) into the mold hole 736 is small. Become.

In the above description, it has been described that the rotation of the handle portion 75 is moved downward and the rotation of the handle portion 75 is moved upward. In this configuration, if the handle portion 75 (drive portion 77) moves under its own weight, the rotation is suppressed and the lock is applied. Accordingly, when the handle portion 75 moves downward due to external vibrations, unintentional rotation of the handle portion 75 can be suppressed. The direction of movement is not limited to this. A configuration may be adopted in which the rotation is suppressed by moving the handle portion 75 in another direction, such as moving upward or moving in the horizontal direction.

In the present embodiment, the knob clutch 97 and the motor clutch 943 are provided such that their positions in the vertical direction can be moved.
As shown in FIG. 18, the knob clutch 97 and the motor clutch 943 are provided so as to engage with each other.

Specifically, the large-diameter portion 975 of the knob clutch 97 is provided such that both sides in the vertical direction are sandwiched between the external tooth portion 943b and the large-diameter portion 943d of the motor clutch 943. In other words, the external tooth portion 943b and the large diameter portion 943d of the motor clutch 943 are provided in the movement path of the large diameter portion 975.
The knob clutch 97 moves in the vertical direction when operated by the operator. As the knob clutch 97 moves, the motor clutch 943 also moves in the vertical direction.

In addition, as the knob clutch 97 and the motor clutch 943 move in the vertical direction, the drive unit 96 is rotated by being driven by the motor 92 (hereinafter sometimes referred to as an electric state), and the drive by the knob clutch 97 is received. Thus, the state in which the drive unit 96 rotates (hereinafter sometimes referred to as a manual state) is switched.

The knob clutch 97 in the present embodiment is an operation unit that is rotated by an operator in order to supply driving force to the driving unit 96 in the manual state, and is in an electric state (first mode) and a manual state (second state). It can be grasped as a member that also serves as an operation unit that performs switching between the modes.

<Switching between electric state and manual state>
FIGS. 20A and 20B are diagrams for explaining the electric state and the manual state. Specifically, FIG. 20A shows an arrangement around the knob clutch 97 and the motor clutch 943 in the electric state, and FIG. 20B shows an arrangement around the knob clutch 97 and the motor clutch 943 in the manual state.
Next, the electric state and the manual state will be described with reference to FIGS. 20 (a) and 20 (b).

First, the electric state will be specifically described with reference to FIG.
In the state shown in FIG. 20A, the knob clutch 97 and the motor clutch 943 are disposed on the lower side. When the knob clutch 97 is disposed on the lower side, the knob clutch 97 is separated from the drive gear 945. That is, the internal tooth portion 979 of the knob clutch 97 is not engaged with the second tooth portion 945c of the drive gear 945. On the other hand, the external tooth portion 943b of the motor clutch 943 is in a state of meshing with the second tooth portion 945c of the drive gear 945.

As a result, the output of the motor 92 is transmitted to the motor clutch 943. The output transmitted from the motor clutch 943 to the drive gear 945 rotates the drive unit 96 (see FIG. 18) via the drive shaft 947.
On the other hand, the knob clutch 97 is separated from the drive gear 945 and is in a free state. Therefore, even if the operator rotates the knob clutch 97 in this electric state, the knob clutch 97 is idled. And the rotational force of the knob clutch 97 is not transmitted to the drive part 96 (refer FIG. 18).

Next, the manual state will be described with reference to FIG.
In the state shown in FIG. 20B, the knob clutch 97 and the motor clutch 943 are disposed on the upper side. When the knob clutch 97 is disposed on the upper side, the inner tooth portion 979 of the knob clutch 97 is engaged with the second tooth portion 945c of the drive gear 945. On the other hand, the external tooth portion 943 b of the motor clutch 943 is in a state where it does not mesh with the second tooth portion 945 c of the drive gear 945.

That is, the motor clutch 943 is away from the drive gear 945 and is in a free state. Therefore, even if the motor 92 is driven, the motor gear 941 and the motor clutch 943 are idled. And the output of the motor 92 is not transmitted to the drive part 96 (refer FIG. 18).
On the other hand, the output transmitted from the knob clutch 97 to the drive gear 945 rotates the drive unit 96 (see FIG. 18) via the drive shaft 947.

Thus, when the knob clutch 97 and the motor clutch 943 move in the vertical direction, the meshing state of the knob clutch 97 and the drive gear 945 is switched, and the meshing state of the motor clutch 943 and the drive gear 945 is switched. In other words, the object in which the drive gear 945 meshes is switched between the knob clutch 97 and the motor clutch 943 by the movement of the knob clutch 97 in the vertical direction.
In other words, by moving the knob clutch 97 in one predetermined direction, the object with which the drive gear 945 is engaged is switched between the knob clutch 97 and the motor clutch 943.

In the illustrated example, the inner tooth portion 943a of the motor clutch 943 is kept engaged with the outer tooth portion 941b of the motor gear 941 regardless of the vertical movement of the motor clutch 943. In other words, even when the motor clutch 943 moves downward (see FIG. 20A), the inner tooth portion 943a of the motor clutch 943 and the outer tooth portion 941b of the motor gear 941 are not separated from each other. Accordingly, it is possible to prevent the gears (the inner tooth portion 943a of the motor clutch 943 and the outer tooth portion 941b of the motor gear 941) from being engaged with each other when switching to the electric state.

In the illustrated example, the potentiometer 93 (see FIG. 18) includes the potentiometer shaft 951 and the first potentiometer gear regardless of the vertical movement of the motor clutch 943 in either the manual state or the electric state. 949, the drive gear 945, and the drive shaft 947 are connected to the drive unit 96 (see FIG. 18). Therefore, the potentiometer 93 can grasp the rotation angle of the drive unit 96 in both the manual state and the electric state.

To further explain, in the illustrated example, the potentiometer 93 is connected to the drive unit 96 (see FIG. 18) even when switching between the manual state and the electric state. Therefore, unlike the illustrated example, the potentiometer 93 can more accurately grasp the rotation angle of the drive unit 96 as compared with the aspect in which the connected state is not maintained.

In the illustrated example, the potentiometer 93 of the composite unit 90 is operated with the same program as the potentiometer 53 of the electric unit 50 shown in FIG. 8, and the gear reduction of the potentiometer 93 with respect to the drive unit 96 (see FIG. 18). The ratio is matched with the gear reduction ratio of the potentiometer 53 (see FIG. 8) with respect to the drive unit 56 (see FIG. 8).
In the illustrated example, an operator who rotates the drive unit 96 (see FIG. 18) in the manual state can grasp the rotation amount of the drive unit 96 with the slide gauge 373 (see FIG. 6).

Here, in the illustrated example, the operator moves the knob portion 973 in the vertical direction and rotates the knob portion 973 while holding the knob portion 973 of the knob clutch 97. Accordingly, for example, the knob portion 973 can be moved in the vertical direction while rotating.

Therefore, for example, when the knob portion 973 is moved in the vertical direction, depending on the relative angle between the knob clutch 97 and the drive gear 945, the teeth of the inner tooth portion 979 in the knob clutch 97 and the second tooth portion 945c in the drive gear 945 There is a case where the teeth come into contact with each other. In this case, the inner tooth portion 979 and the second tooth portion 945c can be engaged with each other by rotating the knob portion 973.

<Switching operation from electric state to manual state>
FIG. 21 is a diagram for explaining the switching operation from the electric state to the manual state.
Next, the switching operation from the electric state to the manual state will be described with reference to FIG.
First, as shown in FIG. 21A, it is assumed that the composite unit 90 is in an electric state. That is, the motor clutch 943 is disposed on the lower side (right side in the figure), and the motor clutch 943 is engaged with the drive gear 945 while the knob clutch 97 is not engaged with the drive gear 945.

Then, as shown in FIG. 21B, when the operator pushes the knob clutch 97 upward (left side in the figure), the large-diameter portion 975 of the knob clutch 97 causes the external tooth portion 943b of the motor clutch 943 to move. Press upward. As a result, the motor clutch 943 moves upward. Then, the internal tooth portion 979 of the knob clutch 97 starts to mesh with the second tooth portion 945c of the drive gear 945.
As the motor clutch 943 is pushed upward, the large-diameter portion 975 of the knob clutch 97 pushes the external tooth portion 943b of the motor clutch 943 upward.

Then, as shown in FIG. 21C, the motor clutch 943 is further pushed upward (left side in the figure). As a result, the meshing width between the inner tooth portion 979 of the knob clutch 97 and the second tooth portion 945c of the drive gear 945 increases. Further, the large diameter portion 975 of the knob clutch 97 pushes the motor clutch 943 further upward.
Then, as shown in FIG. 21 (d), when the knob clutch 97 completes the upward movement, the composite unit 90 enters the manual state. That is, while the knob clutch 97 is engaged with the drive gear 945, the motor clutch 943 is not engaged with the drive gear 945.

<Switching operation from manual state to electric state>
FIG. 22 is a diagram for explaining the switching operation from the manual state to the electric state.
Next, the switching operation from the manual state to the electric state will be described with reference to FIG.
First, as shown in FIG. 22A, it is assumed that the composite unit 90 is in a manual movement state. That is, the motor clutch 943 is arranged on the upper side (left side in the figure), and the knob clutch 97 is engaged with the drive gear 945, while the motor clutch 943 is not engaged with the drive gear 945.

Then, as shown in FIG. 22B, when the operator pulls the knob clutch 97 downward (right side in the figure), the large-diameter portion 975 of the knob clutch 97 becomes the large-diameter portion of the motor clutch 943. Push 943d downward. As a result, the motor clutch 943 moves downward. Then, the external tooth portion 943b of the motor clutch 943 starts to mesh with the second tooth portion 945c of the drive gear 945.
As the motor clutch 943 is pulled downward, the large diameter portion 975 of the knob clutch 97 pushes the large diameter portion 943d of the motor clutch 943 downward.

Then, as shown in FIG. 22C, the motor clutch 943 is further pulled out downward (right side in the figure). As a result, the meshing width between the external tooth portion 943b of the motor clutch 943 and the second tooth portion 945c of the drive gear 945 increases. Further, the large diameter portion 975 of the knob clutch 97 pushes the motor clutch 943 further downward.
Then, as shown in FIG. 22 (d), when the knob clutch 97 completes the downward movement, the composite unit 90 is in an electric state. That is, while the motor clutch 943 is engaged with the drive gear 945, the knob clutch 97 is not engaged with the drive gear 945.

Now, in the example shown in the drawing, the manual clutch state or the electric state is selected alternatively by switching the position of the knob clutch 97 in the vertical direction. Therefore, it is driven from both the knob clutch 97 and the motor 92 that are driven by both the knob clutch 97 and the motor 92, that is in the manual state and in the electric state, and that is neither in the manual state nor in the electric state. It is avoided that it does not receive.

In the illustrated example, the motor 92 is disconnected from the knob clutch 97 in both the manual state and the electric state.
As a result, when the operator turns the knob clutch 97 in the manual state, it is not necessary to apply a rotational force for turning the motor 92. As a result, the operability of the knob clutch 97 is improved. Further, by rotating the motor 92 in the reverse direction (back drive), for example, an electromotive force is generated in the motor 92 and damage to a commutator (not shown) provided in the motor 92 is suppressed.

Furthermore, the rotation of the knob clutch 97 is suppressed when the motor 92 is driven in the electric state. Further, when the motor 92 is driven in the electric state, even when the knob clutch 97 receives an external force due to an operator touching it, the motor 92 is prevented from being loaded with the external force.

In the illustrated example, the knob clutch 97 receives a downward force due to its own weight, and the lower side (predetermined one direction) is also applied by a leaf spring 955 (see FIG. 18) which is an example of an urging mechanism. Is in the opposite direction). Therefore, in the illustrated example, when the knob clutch 97 is not receiving external force, it is in an electric state. Further, when the force of the direction in which the knob clutch 97 is moved upward is received, the electric state is switched to the manual state.

Here, in the manual state, an operator is always present at the place where the composite unit 90 is installed in order to operate the knob clutch 97. On the other hand, in the electric state, the worker is not always present at the place where the composite unit 90 is installed. Furthermore, it is not necessary to set the manual state when there is no worker.
Therefore, as in the example shown in the figure, when the knob clutch 97 is not receiving external force, it is in an electric state. As a result, for example, even if the operator forgets to return the knob clutch 97 from the manual state to the electric state, the drive unit 96 can be rotated by the motor 92.

Note that here, switching between the manual state and the electric state as the operator operates (pushes in or pulls forward) the knob clutch 97 has been described. However, the present invention is not limited to this, and the knob clutch 97 may be moved by its own weight or the urging force of the leaf spring 955 to switch between the manual state and the electric state.
