Description

The present invention relates to technology for pedestals on which cameras are mounted.

Various holding devices have been proposed for use in holding cameras. A pedestal that can change the position in the vertical direction (height direction) while holding the camera is one type of the holding device as described above.

For example, Patent Literature 1 discloses a pedestal that can change the position of the camera in the height direction by expanding and contracting a telescopic pole connected to a camera fixing portion on which the camera is mounted. Then, the extensible pole is expanded and contracted by directly manipulating the extensible pole by means of an extensible means (hydraulic cylinder or ball screw).

Specifically, the camera holding unit 20 is a part for attaching a connecting device (for example, a camera platform or an adapter 212 described later) that is directly connected to the camera, and indirectly holds the camera via the connecting device. It is a mechanism for A specific configuration of the camera holding section 20 will be described later.

The pole portion 30 is a shaft-shaped member extending in the X direction and can be expanded and contracted. Specifically, the pole portion 30 is provided with the camera holding portion 20 at the tip (end portion on the positive side in the X direction). Therefore, by expanding and contracting the pole portion 30, the position of the camera provided on the camera holding portion 20 in the height direction can be changed. Note that the X direction can also be said to be the direction in which the pole portion 30 extends. The pole portion 30 is expanded and contracted by the drive portion 80 . Specific configurations of the pole portion 30 and the driving portion 80 will be described later.

The tripod 50 of the first embodiment is extendable. As illustrated in FIG. 1, the tripod 50 includes three legs 51 and two locking mechanisms L (L1, L2). Each leg 51 includes a first portion 511 , a second portion 512 and a third portion 513 . FIG. 1 illustrates a case where the lengths of the first portion 511, the second portion 512, and the third portion 513 are substantially the same. The lengths of the first portion 511, the second portion 512, and the third portion 513 are, for example, approximately 30 to 100 cm. An end T3 of the leg portion 51 on the side of the camera holding portion 20 is an end portion T1 of the tripod 50, and an end portion T4 of the leg portion 51 on the side opposite to the camera holding portion 20 is an end portion T2 of the tripod 50. can also be rephrased.

The tripod 50 is connected to the pole portion 30 so that each leg portion 51 can move toward and away from the pole portion 30 with the end portion T4 side thereof centering on the end portion T3.

When the tripod 50 is in the extended state (in the case of FIG. 1), the third portion 513 is located on the side of the camera holding section 20, and the first portion 511 is located on the side opposite to the third portion 513. The second portion 512 is a portion located between the third portion 513 and the first portion 511 . On the other hand, when the tripod 50 is in the contracted state (in FIGS. 2 and 3), the first portion 511, the second portion 512 and the third portion 513 are positioned so as to overlap each other. Specifically, the first portion, the second portion 512 and the third portion 513 overlap each other so that the positions in the height direction are the same over the entire length.

The first embodiment exemplifies a configuration in which the first portion 511 includes one shaft member, the second portion 512 includes two shaft members, and the third portion 513 includes two shaft members. When the tripod 50 is in a telescopic state, as illustrated in FIGS. 2 and 3, one shaft member in the first portion 511 is positioned between two shaft members in the second portion 512, The two shaft members in second portion 512 are positioned between the two shaft members in third portion 513 .

As illustrated in FIG. 1, the leg portion 51 can be extended by sliding the second portion 512 relative to the first portion 511 to the side opposite to the end portion T2. After the second portion 512 is slid to an arbitrary position with respect to the first portion 511, the second portion 512 can be fixed with respect to the first portion 511 using the locking mechanism L1. Similarly, by sliding the third portion 513 with respect to the second portion 512 to the side opposite to the end portion T2, the leg portion 51 can be further extended. After the third portion 513 is slid to an arbitrary position with respect to the second portion 512, the third portion 513 can be fixed with respect to the second portion 512 using the locking mechanism L2.

The lock mechanism L1 is provided at one end of the second portion 512 (the end on the dolly 100b side), and the lock mechanism L2 is provided on the other end of the second portion 512 (the end on the camera holding section 20 side). provided in Although the specific configuration of the lock mechanisms L1 and L2 is arbitrary, for example, a mechanism that can fix the positions of the second portion 512 and the third portion 513 by screwing through a knob is appropriately adopted. be done.

As illustrated in FIG. 1, both the second portion 512 and the third portion 513 can be slid from the first portion 511 and the second portion 512, respectively, but the second portion 512 is not slid. It is also possible to slide only the third portion 513 from the second portion 512 . Also, the second portion 512 and the third portion 513 can be slid an arbitrary length (distance) with respect to the first portion 511 and fixed.

A specific configuration of each leg portion 51 is not limited to the above configuration as long as it can be expanded and contracted. However, from the viewpoint of ensuring stability while increasing the extension length, it is preferable that each leg 51 include a first portion 511, a second portion 512, and a third portion.

Dolly 100b is a mechanism that allows pedestal 100a to move, and is connected to end T2 of tripod 50, as described above. The dolly 100b of the first embodiment is detachably connected to the end T2. FIG. 4 is a perspective view of the dolly 100b removed from the tripod 50. FIG. FIG. 5 is a perspective view of the tripod 50 with the dolly 100b removed.

As illustrated in FIG. 4, the dolly 100b of the first embodiment includes three casters 61 and connecting members 62. As shown in FIG. The connecting member 62 includes three shaft members 621 (a, b, c) and three first connecting members 623 . A caster 61 is provided at one end of the shaft member 621 . The other end of the shaft member 621 is interconnected with two other shaft members 621 via a connecting member 625 . Each shaft member 621 is arranged around the connecting member 625 at approximately 120° intervals. For the connecting member 625, it is preferable to use, for example, a mechanism that can be miniaturized so that the other two shaft members 621a and 621b approach one shaft member 621c when the pedestal 100a is not in use.

A first connection member 623 is provided on the surface of the shaft member 621 opposite to the surface on which the casters 61 are provided. The first connecting member 623 is a member for connecting with the end T4 of the leg 51 of the tripod 50 . As illustrated in FIG. 5 , the tripod 50 includes a second connection portion 520 connected to the first connection member 623 on the end T4 side of each leg portion 51 of the tripod 50 . The second connection portion 520 has a shape that fits into the fitting portion P1 of the first connection member 623 . For example, the fitting portion P1 is a shaft-shaped member, and the second connection portion 520 includes a concave portion P2 that fits into the fitting portion P1. The first connection member 623 may include a grip portion R that is gripped when fitting the second connection portion 520 of the leg portion 51 to the first connection portion 623 . The shape of the grip portion R is arbitrary. Note that the configurations of the first connection portion 623 and the second connection portion 520 are not limited to the above examples as long as they can be connected to each other.

By connecting the three first connection members 623 to the second connection portions 520 of the three legs 51, respectively, each of the legs 51 is provided at a position corresponding to the end T4 of each leg 51, as illustrated in FIG. Casters 61 are connected. Since the dolly 100b is detachable from the tripod 50, it can be removed from the tripod 50 when the pedestal 100a is not used.

FIG. 6 is a cross-sectional view focusing on the pole portion 30. As shown in FIG. In FIG. 6, illustration of the tripod 50 and the dolly 100b is omitted for the sake of convenience. As illustrated in FIG. 6, the pole portion 30 of the first embodiment includes a first member 31, a second member 32, a fixed member 33 and a movable member .

The first member 31 includes a side portion 311 and a bottom portion 313 . The side surface portion 311 is a tubular (typically cylindrical) member extending along the X direction. The bottom surface portion 313 is a portion that closes the opening located on the opposite side (the negative side in the X direction) of the side surface portion 311 from the camera holding portion 20 .

The side portion 311 includes a first section K1 and a second section K2 from the negative side to the positive side in the X direction. A bottom portion 313 is positioned at the end of the first section K1 opposite to the second section K2. The length of the second section K2 is sufficiently longer than that of the first section K1, for example 30-80 cm. On the other hand, the length of the first section K1 is, for example, 8-20 cm.

The second member 32 is a tubular (typically cylindrical) member extending along the X direction. Specifically, the second member 32 is movable in the vertical direction (the positive side and the negative side in the X direction) while being inserted inside the second section K2 of the side portion 311 of the first member 31. . Specifically, the second member 32 (the negative end in the X direction) is movable between the negative end in the X direction and the positive end in the second section K2.

A state in which the second member 32 (the end on the negative side in the X direction) is closest to the bottom surface portion 313 of the first portion 511 is a state in which the pole portion 30 is most shortened. On the other hand, when the second member 32 (the end on the negative side in the X direction) is at the farthest position from the bottom surface portion 313 of the first portion 511, the pole portion 30 is in the most extended state. In other words, the first section K1 is a portion of the first member 31 that does not overlap the second member 32 when the pole portion 30 is most shortened (a portion in which the second member 32 is not positioned).

The length of the second member 32 is, for example, 30-80 cm. FIG. 6 illustrates a configuration in which the length of the second member 32 and the length of the second section K2 are the same. The negative end in the X direction of the second member 32 is located above the positive end in the X direction in the first section K1 (for example, in the X direction in the second section K2) when the pole portion 30 is most shortened. (near the negative end of the Note that the length of the second member 32 may be shorter than the second section K2 of the first member 31, but from the viewpoint of sufficiently shortening the pole portion 30 while ensuring the length for extending the pole portion 30. Therefore, a configuration in which the length of the second member 32 is approximately the same as the length of the second section K2 of the first member 31 is preferable.

The fixing member 33 is a tubular (typically cylindrical) member extending along the X direction. Specifically, the fixing member 33 is positioned inside the second member 32 and fixed to the first member 31 . In the first embodiment, it is fixed to a portion of the first portion 511 that does not overlap the second member 32 in the state where the pole portion 30 is most shortened (that is, the state where the second member 32 is positioned on the most negative side in the X direction). Member 33 is fixed. For example, the fixing member 33 (the end on the negative side in the X direction) is fixed to the bottom surface portion 313 of the first member 31 . However, the fixing member 33 may be fixed to the side surface (inner peripheral surface) of the first member 31 in the first section K1.

The length of the fixing member 33 is such that the end of the fixing member 33 on the positive side in the X direction is located on the negative side in the X direction with respect to the end of the first member 31 on the positive side in the X direction. The X-direction negative side end of 33 is set to be positioned within the first section K1 of the first member 31 .

The moving member 34 is a shaft-shaped member extending along the X direction. Specifically, the moving member 34 is vertically movable while being inserted inside the fixed member 33 . The moving member 34 is vertically moved by the drive unit 80 .

The length of the moving member 34 is set, for example, so that the positive end of the moving member 34 in the X direction is substantially at the same position as the positive end of the second member 32 in the X direction. It should be noted that the moving member 34 does not have to be positioned inside the fixed member 33 over the entire length when the pole portion 30 is most stretched. Note that the moving member 34 may be formed by connecting a plurality of members. Further, the length of each member (31 to 34) of the pole portion 30 can be appropriately changed according to the desired length (stroke length) of the pole portion 30 to be extended.

The second member 32 is connected to the moving member 34 and moves vertically in conjunction with the moving member 34 . Any method can be used to connect the moving member 34 and the second member 32 . For example, the moving member 34 and the second member 32 are indirectly connected via the cover member J. The end of the moving member 34 on the positive side in the X direction is connected to the surface of the first member 31 of the cover member J on the side of the bottom surface 313 (negative side in the X direction). The camera holding portion 20 is connected to the surface of the cover member J on the side opposite to the bottom portion 313 of the first member 31 (positive side in the X direction). However, as long as the second member 32 can move vertically in conjunction with the moving member 34, the connection method between the moving member 34 and the second member 32 is not limited to the above example. The two members 32 may be directly connected. The elements of the pedestal 100a (the camera holder 20, the first member 31, the second member 32, the cover member J, etc.) are connected to each other by appropriately using connecting members such as screws.

The driving section 80 expands and contracts the pole section 30 by moving the moving member 34 in the vertical direction (the positive side and the negative side in the X direction). For example, a motor or the like is used as the drive unit 80 . The driving portion 80 and the moving member 34 are connected so that the power of the driving portion 80 can be transmitted to the moving member 34 . In the first embodiment, the driving portion 80 is accommodated inside the first section K1 (that is, the portion where the second member 33 does not overlap) of the first member 31. As shown in FIG.

FIG. 6 illustrates a configuration in which the diameter of the first section K1 in which the drive section 80 is accommodated (the cross-sectional area when viewed from the X direction) is larger than the diameter of the second section K2. For example, the diameter of the first section K1 is about 8-20 cm, and the diameter of the second section K2 is about 8-13 cm. The diameter of the first section K1 may be equal to or smaller than the diameter of the second section K2.

As understood from the above description, the pole portion 30 of the first embodiment includes the first member 31, the second member 32, the fixed member 33, and the moving member 34, and the second member 32 interlocks with the moving member 34. to move up or down. Therefore, for example, the strength of the pole portion 30 can be increased compared to the case where the pole portion is composed of the fixed member 33 and the moving member 34 without the first member 31 and the second member 32 . In addition, in the first embodiment, since the driving portion 80 is accommodated inside the first section K1 of the first member 31 (that is, the portion of the first portion 31 that does not overlap the second member 32), the second member 32 The driving part 80 can be accommodated in the pole part 30 without obstructing the movement of the pole part 30.例文帳に追加However, the specific configuration of the pole portion 30 is not limited to the above examples as long as it can be expanded and contracted.

The drive unit 80 expands and contracts the pole unit 30 according to instructions from the operation device 90 . The drive section 80 of the first embodiment changes the speed at which the pole section 30 expands and contracts according to instructions from the operating device 90 . Details of the operation device 90 will be described later.

In the first embodiment, the pedestal 100a is provided with a bearing 70 for facilitating the movement of the second member 32. As shown in FIG. Specifically, the bearing 70 is provided at a position that contacts the outer peripheral surface of the second member 32 (the surface facing the inner peripheral surface of the first member 31). The bearing 70 is provided at the end of the first member 31 on the side of the camera holding section 20 .

As illustrated in FIG. 6, the bearing 70 is a bearing holder H provided on the outer peripheral surface of the first member 31 so as to pass through the side surface of the first member 31 and come into contact with the outer peripheral surface of the second member 32. Supported by The first embodiment exemplifies a configuration in which a plurality of bearings 70 (70a, 70b) are provided at two different positions in the X direction. Furthermore, two bearings 70a are provided so as to be adjacent along the circumferential direction. Similarly, two bearings 70b are provided adjacent to each other along the circumferential direction. That is, one bearing holder H accommodates a bearing group consisting of four bearings 70 . The bearing groups (bearing holders H) are installed, for example, at three locations every 120° along the circumferential direction of the first member 31 . That is, the pedestal 100a has three bearing holders H and twelve bearings 70 in total.

Note that the number of bearings 70 and the positions where the bearings 70 are installed are not limited to the above examples. However, a plurality of bearings 70 (70a, 70b) are provided at two locations at different positions in the X direction, and the plurality of bearings 70 groups are arranged at a plurality of locations along the circumferential direction of the first member 31 (three locations in FIG. 6). ), the vertical movement of the second member 32 can be made smoother, and the stability of the second member 32 can be improved.

As exemplified in FIG. 1, the camera holding portion 20 is a member at the end of the pedestal 100a on the positive side in the X direction. Specifically, as illustrated in FIG. 6, the camera holding portion 20 is positioned at the end of the second member 32 opposite to the bottom surface portion 313 of the first member 31 (the end on the positive side in the X direction). provided in Any method can be used to connect the camera holding portion 20 and the second member 32 . For example, as illustrated in FIG. 6, the camera holding section 20 is connected via a cover member J that closes the X-direction opening of the second member 32 .

As illustrated in FIGS. 1 and 6, for example, the camera holding section 20 includes a placement section 21 on which the camera is placed at the end on the positive side in the X direction. The mounting portion 21 is a portion for mounting a connecting device (for example, a camera platform or an adapter 212 described later) that is directly connected to the above-described camera. The shape of the mounting portion 21 can be appropriately changed according to the type of camera to be mounted. In the first embodiment, a semicircular (ball-shaped) mounting portion 21 curved toward the negative side in the X direction is illustrated. When a camera (for example, a PTZ (Pan Tilt Zoom) camera) having a flat portion in contact with the mounting portion 21 is held by the camera holding portion 20, the surface of the mounting portion 21 (the positive side in the X direction) surface) should be flat. For example, as illustrated in FIG. 1, by connecting a disc-shaped adapter 212 that closes the opening of the semicircular mounting portion 21 to the mounting portion 21, the surface of the mounting portion 21 is flattened. can do. The adapter 212 is attachable to and detachable from the mounting section 21 . A screw that can be connected to a camera is provided at the center of the surface of the adapter 212 (surface on the positive side in the X direction).

As understood from the above description, the pedestal 100a of the first embodiment can be used for various cameras by changing the shape of the camera holding section 20. FIG. Note that the shape of the camera holding portion 20 is not limited to the above examples. Also, a spirit level (FIG. 6) may be provided in the camera holding section 20. FIG.

The pedestal set 100 of the first embodiment further has an operating device 90 . The operating device 90 is a device for transmitting an instruction to expand and contract the pole section 30 to the driving section 80 according to an operation by a user. The operation device 90 of the first embodiment is a separate device from the pedestal 100a, and is connected to the pedestal 100a by wire or wirelessly (for example, short-range wireless communication). From the viewpoint of not causing a delay in the time from when the user operates the operator 92 to when the pole portion 30 actually expands and contracts, it is preferable to connect the operation device 90 and the pedestal 100a by wire. Note that the operating device 90 and the pedestal 100a may be directly connected, or may be indirectly connected via another member or wiring.

The operating device 90 of the first embodiment transmits to the driving section 80 a first instruction to extend the pole portion 30 and a second instruction to shorten the pole portion 30 . 7 and 8 are diagrams relating to an example of the operating device 90. FIG. FIGS. 7 and 8 show Y, Z and W directions which are orthogonal to each other. 7 is a diagram when viewed from the negative side in the W direction, and FIG. 8 is a diagram when viewed from the negative side in the Z direction.

As illustrated in FIGS. 7 and 8 , the operating device 90 includes, for example, a base portion 91 and an operator 92 provided on the base portion 91 . The base portion 91 has a substantially rectangular parallelepiped shape elongated along the Y direction, for example, so that the user can easily hold it by hand. For example, the operator 92 is provided on the side surface of the base portion 91 on the positive side in the Y direction. As illustrated in FIG. 8, the W-direction negative side surface of the operator 92 and the W-direction negative side surface of the base portion 91 are connected so as to be continuous.

As illustrated in FIGS. 7 and 8, the manipulator 92 is pivotally supported by the base portion 91 so as to be rotatable about the central axis F. As shown in FIGS. Specifically, when the manipulator 92 rotates in one direction (for example, clockwise) about the central axis F, it transmits a first instruction to the drive unit 80, and rotates about the central axis F in the other direction (for example, counterclockwise). clockwise), it transmits a second instruction to the drive unit 80 . Therefore, the pole portion 30 can be extended and contracted by a simple operation of rotating the manipulator 92 in one or the other direction. For example, the manipulator 92 is rotatable in one direction and the other from a reference position. Note that the reference position is a position where the manipulator 92 is not rotated in either direction. 7 and 8 are diagrams showing a state in which the manipulator 92 is at the reference position.

The first instruction in the first embodiment is an instruction to extend the pole at a speed corresponding to the rotation angle at which the manipulator 92 rotates in one direction. Specifically, the first instruction is an instruction to extend the pole at a speed corresponding to the rotation angle at which the manipulator 92 rotates in one direction from the reference position. For example, the larger the rotation angle, the faster the extension speed, and the smaller the rotation angle, the slower the extension speed.

The second instruction according to the first embodiment is an instruction to shorten the pole at a speed corresponding to the rotation angle at which the manipulator 92 rotates in the other direction. Specifically, the second instruction is an instruction to shorten the pole at a speed corresponding to the rotation angle at which the manipulator 92 rotates in the other direction from the reference position. For example, the larger the rotation angle, the faster the shortening speed, and the smaller the rotation angle, the slower the shortening speed. In addition, in the case of adopting the manipulator 92 that can rotate in both directions about the reference position, the manipulator 92 returns to the reference position when the rotation in one direction or both directions is released (when the manipulator 92 is released). It may be pivotally supported on the base portion 91 by an elastic member such as a spring so as to return.

As can be understood from the above description, by operating the manipulator 92 rotatable about the central axis F, it is possible to simultaneously issue an instruction to extend/retract the pole portion 30 and an instruction to specify the speed of the extension/retraction. can. However, the configuration of the operator 92 is not limited to the above example. For example, a disk-shaped operating element that can rotate in both directions around a midpoint may be employed. Also, the manipulator 92 does not have to rotate around the reference position.

The driving section 80 extends and contracts the pole section 30 according to instructions (first instruction, second instruction) from the operating device 90 . Furthermore, the driving section 80 of the first embodiment changes the speed at which the pole section 30 expands and contracts according to instructions from the operating device 90 . That is, the speed at which the pole portion 30 expands and contracts is changed according to the rotation angle of the manipulator 92 . Therefore, there is an advantage that the position in the height direction of the camera can be changed at a speed desired by the user.

Note that the operating device 90 has a surface (the surface on the negative side in the W direction) of the base portion 91 and a A concave portion 93 may be provided over both the surface (surface on the negative side in the W direction).

According to the operating device 90 of the first embodiment, there is an advantage that an instruction for shortening or extending the pole portion 30 and an instruction for the speed of shortening and expanding/contracting can be transmitted to the driving portion 80 by a simple operation. However, the specific configuration of the operating device 90 is not limited to the above examples. For example, a terminal device such as a smart phone may be used as the operation device 90 . Further, for example, when the speed of expansion and contraction of the pole portion 30 is not variable, the operating device 90 can operate the operator for giving the first instruction (extend) and the operator for giving the second instruction (shorten). A configuration including may also be employed.

As can be understood from the above description, in the first embodiment, the pole portion 30 having the camera holding portion 20 at its tip can be expanded and contracted by the drive portion 80 that receives an instruction from the operation device 90 . Therefore, compared with the structure (for example, patent document 1) which expands and contracts a pole part manually, a pole part can be expanded-contracted easily. Further, in the first embodiment, the height position of the camera can be changed by expanding and contracting the tripod 50 connected to the pole portion 30 . Therefore, compared to the pedestal 100a, for example, in which the camera expands and contracts only by expanding and contracting the pole portion 30, it is possible to increase the length of expansion while maintaining stability.

Furthermore, in the first embodiment, by operating the operating device 90 separate from the pedestal 100a, it is possible to transmit an instruction to extend or retract to the drive unit 80, so there is the advantage that the position of the camera in the height direction can be changed by remote control. There is also However, the operating device 90 is not limited to a configuration that is separate from the pedestal 100a. For example, the operating device 90 may be provided integrally with the pedestal 100a (for example, the pole portion 30). However, from the viewpoint of enabling remote control, a configuration that is separate from the pedestal 100a is preferable.

The height of the pedestal 100a of the first embodiment is assumed to be about 100 cm, for example, in the most shortened state of FIG. , in the most extended state of FIG. 1 (that is, the state in which both the pole portion 30 and the tripod 50 are most extended), about 250 cm is assumed.

<Second embodiment>
A second embodiment will be described. In addition, in each embodiment illustrated below, the reference numerals used in the description of the first embodiment are used for elements whose functions are the same as those of the first embodiment, and detailed description of each will be omitted as appropriate.

In recent years, there has also been a desire to use the pedestal 100a as a stationary type (that is, to use the pedestal 100a in a fixed manner) while allowing the pedestal 100a to be freely moved by the dolly 100b. For example, a configuration is conceivable in which the pedestal 100a is fixed by providing stoppers on the casters and stopping the casters with the stoppers. However, when the casters are fixed by the stoppers, there is a problem that the pedestal 100a cannot be firmly fixed and lacks stability.

Therefore, in the pedestal 100a according to the second embodiment, both the dolly 100b and the spreader 100c that allows the pedestal 100a to be fixed are detachable. FIG. 9 is a perspective view of the spreader 100c, and FIG. 10 is a perspective view of the pedestal 100a with the spreader 100c attached. The pedestal 100a in the second embodiment is the same as in the first embodiment.

As illustrated in FIG. 9, it has three shaft members 631 and three first connecting members 633 . Each shaft member 631 is a belt-like member and can be expanded and contracted. After the shaft member 631 is adjusted to the desired length, it is fixed by the fixing portion S. The three shaft members 631 are arranged at approximately 120° intervals around one end of each shaft member 631 . A first connection member 633 is provided at the other end of each shaft member 631 . The first connection member 633 has a fitting portion P1 that fits into the concave portion P2 of the second connection portion 520 of the tripod 50, and a gripping portion P1 that fits into the concave portion P2 of the second connection portion 520 of the tripod 50, similarly to the first connection member 623 that the dolly 100b of the first embodiment has. Part R.

As can be understood from the above description, in the second embodiment, both the pedestal 100a and the dolly 100b can be detachably connected, so that the spreader 100c and the dolly 100b can be appropriately replaced depending on the application. .

In the first embodiment, the pedestal set 100 has the dolly 100b, but the pedestal set 100 may have the spreader 100c instead of the dolly 100b. That is, a pedestal set 100 according to the second embodiment includes a pedestal 100a and at least one of a dolly 100b and a spreader 100c.

The end T2 side of the tripod 50 can extend and contract in a configuration in which both the dolly 100b that allows the pedestal 100a to move and the spreader 100c that allows the pedestal 100a to be fixed are detachably connected. It is not essential that the tripod 50 is provided and that the drive section 80 extends and retracts the pole section according to instructions from the operation device 90 . That is, it comprises a camera holding portion 20 for holding a camera, a telescopic pole portion 30 provided with the camera holding portion 20 at its tip, and a tripod 50 having one end T1 side connected to the pole portion 30. The other end T2 of the tripod 50 can be used as a pedestal 100a to which both a dolly 100b that allows the pedestal 100a to move and a spreader 100c that allows the pedestal 100a to be fixed are detachably connected. I can conceive. The pedestal 100a has the advantage that it can be used by appropriately switching between a movable state and a firmly fixed state.
