Field of the Invention The present invention relates to a so-called movie camera such as a movie camera and a video camera, and a device for supporting an article to be used in a specific direction such as a microphone, a speaker, and a light (illumination). ,Especially,
The present invention relates to an article support device suitable for supporting the article so that the position and direction of the article can be freely changed.

[0002]

2. Description of the Related Art The applicant of the present invention has proposed a photographing crane device disclosed in Japanese Patent Laid-Open No. 5-161037 as a device suitable for supporting the above-mentioned movie camera. This device has two sub-beams offset and arranged parallel to each other on one side of one main beam. With these three beams extending in the X direction in the three-dimensional direction, one end, the other end and The configuration is such that the substantially central portion is connected by a bracket via a universal joint having two axes extending in the Y-axis and Z-axis directions. Then, attach a camera and a weight to each bracket at both ends, attach the center bracket to a tripod platform, etc., and align the center of gravity of the whole with the center of gravity of the support bracket to facilitate small-scale crane shooting. It is the one.

In this crane device, not only the position of the camera is moved, but also the Y-axis and Z-axis of the universal joint can be used to pan (horizontal swing) and tilt (vertical swing) the camera. It is like this. The pan is performed by moving the main beam and the sub beam relatively in the longitudinal direction, and the tilt is performed by relatively moving the left and right sub beams in the longitudinal direction.

[0004]

The above-mentioned conventional crane device is capable of panning and tilting by combining one main beam and two sub-beams, but these operations are performed accurately and smoothly. In order to achieve this, the assembling precision such as the parallelism between the beams and the mounting position of each bracket must be high. However, since there are three beams, the structure is complicated and it is difficult to improve the assembly accuracy. In addition, it was found that there are points to be improved, such as an increase in the number of parts, which leads to an increase in manufacturing cost and a deterioration in transportability and assembling due to an increase in weight.

The present invention has been made in view of the above circumstances. By simplifying the structure, the assembling accuracy can be easily increased, and the increase in the number of parts and the accompanying increase in the manufacturing cost and the increase in the weight can be suppressed and used. It is an object of the present invention to provide an article supporting device for direction change that is easy and functionally excellent.

[0006]

The present invention achieves the above object by the following means. That is, in the article supporting apparatus according to claim 1, an operating unit and an operated unit having the same structure are respectively provided at the base end portion and the tip end portion of the beam having a predetermined length, and these units are provided in the beam. A bracket that is rotatably supported via a first rotation shaft that is orthogonal to the longitudinal direction of the, and a bracket that is coaxially arranged with the first rotation shaft and that is rotatably supported by the bracket and the beam. The second rotation axis and the bracket,
A third rotating shaft, which is rotatably supported in a state where its axis line is orthogonal to the first and second rotating shafts, and the third rotating shaft and the second rotating shaft are connected to each other. A rotation transmission mechanism that transmits rotation of one of the rotation shafts to the other is provided, and the operation unit and the operated unit are provided between the first rotation shaft and the second rotation shaft. , The first extending along the beam
The endless belt and the second endless belt are connected to each other by being wound, and the operator is provided on the third rotation shaft of the operation unit, and the article is provided on the third rotation shaft of the operated unit. The feature is that each can be attached.

According to a second aspect of the present invention, the operating element is constituted by a member formed in a rod shape or a long plate shape capable of setting the longitudinal direction, and the longitudinal direction is set parallel to the directing direction of the article. I am trying. According to a third aspect of the present invention, an arbitrary supporting point set between the operating unit and the operated unit in the beam is supported on the supporting member so as to be swingable at least in the vertical direction or the horizontal direction, and the beam is supported by the beam. With the balancer provided, the center of gravity of the whole
It is characterized in that it is located at an arbitrary position on the vertical line passing through the support point. According to a fourth aspect of the present invention, the beam is attached to the support member so as to be rotatable about its own axis.

According to the present invention, when the bracket of the operation unit is rotated about the first rotation axis together with the third rotation axis by using the operator, the rotation causes the first endless belt to rotate. The article, which is transmitted to the first rotation shaft and the bracket of the operated unit via the third rotation shaft, is rotated about the first rotation shaft in the same direction and at the same angle as the operator. To do. Further, when the third rotation shaft of the operation unit is rotated around the shaft by the operator, the rotation is performed from the rotation transmission mechanism of the operated unit through the second rotation shaft to the second endless belt. Further, it is transmitted from the second endless belt to the third rotation shaft via the second rotation shaft of the operation unit and the rotation transmission mechanism. As a result, the article is rotated about the third rotation axis,
It rotates in the same direction and at the same angle as the operator. That is, a remote operation is performed in which the movement of the operator attached to the operation unit at the base end of the beam is transmitted in exactly the same manner to the article attached to the operated unit at the tip of the beam.

Further, an arbitrary supporting point set between the operating unit and the operated unit on the beam is supported by the supporting member so as to be swingable at least in the up-down direction or the left-right direction, and a balancer provided on the beam. By locating the center of gravity of the entire body at an arbitrary position on the vertical line passing through the support point, the beam can be rocked with a very small force, and the burden on the operator is greatly reduced. Further, by attaching the beam to the support member so as to be rotatable about the axis, after rotating the article about the third rotation axis,
By rotating the beam in the direction opposite to the rotating direction of the article, the horizontality of the directivity of the article can be corrected.

That is, the center of gravity of the entire body is located at an arbitrary position on the vertical line passing through the supporting point S of the beam 10. Regarding the position of the support point S, the photographer holds the grip 71 with one hand and the operation plate 5 with the other hand.
1 is the operable range. For example, the operation unit 1
It is preferable that the position is about 1/4 to 1/5 of the length of the beam 10 from 1A.

B-2. Basic posture of the crane device The axial direction of the grip 71 is along the vertical direction, the beam 10 is horizontal, and the direction of the camera C and the operation plate 51 are aligned along this beam 10, and these three directions (when viewed from above) ( Longitudinal direction of beam 10, optical axis of camera C, operation plate 51
Crane device 1 when the longitudinal direction of the
It is defined as the basic posture of.

B-3. Photographing by camera The photographer holds the grip 71 straight with one hand in the vertical direction to float the entire crane apparatus 1 and faces the front of the camera C side, and operates the operation plate 51 with the other hand to change the basic posture from the basic posture. Various images can be taken by moving the camera C or changing the angle. The operation patterns are basically the following five. It should be noted that when taking a picture, the image taken by the camera C is monitored on the monitor M.

(1) Operation pattern 1: Horizontal rotation of camera position From the basic posture, the beam C is horizontally swung together with the operation plate 51 around the grip 71, whereby the camera C horizontally swivels left and right.

(2) Operation pattern 2: Vertical movement of camera position From the basic posture, the beam 10 is moved together with the operation plate 51 with the horizontal pin 66 connecting the fork 68 and the collar 64 as an axis.
By tilting up and down, the camera C
Moves up and down.

(3) Operation pattern 3: horizontal movement of camera angle-pan Using the operation plate 51, the bracket 13 of the operation unit 11A is rotated to the left and right around the first rotation shaft 19 as an axis. The rotation of the bracket 13 of the operation unit 11A is transmitted to the first rotation shaft 19 and the bracket 13 of the operated unit 11B via the first belt 43, and the camera C is in the same direction and at the same angle as the operation plate 51. Swing left or right, that is, pan.

(4) Operation pattern 4: Rotation around the optical axis of the camera The operation plate 51 is rotated clockwise or counterclockwise about the third rotation shaft 30. The rotation of the operation plate 51
In the operation unit 11A, from the bevel gear 31 to the second
Is transmitted to the second belt 44 via the rotary shaft 22 of the driven unit 11B, and is transmitted from the belt 44 to the third rotary shaft 30 via the second rotary shaft 22 of the operated unit 11B and the bevel gear 31. The camera C rotates around the optical axis in the same direction and at the same angle as the operation plate 51 together with the third rotation shaft 30 of.

(5) Operation pattern 5: Rotation around the beam axis of the camera Using the operation plate 51 and the housing 12 of the operation unit 11A, or by grasping the beam 10 itself, the beam 10
Is rotated about the axis by using the collar 64 as a bearing. The camera C rotates about the beam 10 and moves its position within a narrow range. In this operation, the above operation pattern 4
Thus, by rotating the camera C in the direction opposite to the rotating direction of the beam 10, the horizontality of the camera C can be constantly corrected and maintained.

The above is the basic operation pattern of the crane apparatus 1 of the present embodiment. By moving the beam 10 to the left or right or up and down, it is possible to perform moving image capturing in which the position of the camera C is greatly moved (operation patterns 1 and 2). Further, by rotating the beam 10 around the axis, the position of the camera C can be moved within a narrow range (operation pattern 5). Further, the operation is performed by operating the operation plate 51 attached to the operation unit 11A.
It is transmitted in exactly the same way to the camera C attached to the operated unit 11B at the tip of 0. That is, it is possible to remotely operate the camera C, which is located far away from the hand, by the operation plate 51 (operation patterns 3 and 4).

By performing a combination of a plurality of the above five basic operation patterns at the same time or changing the way of holding the grip 71, a complicated operation can be given to the camera C to perform various angle conversions and moving photographing. . Here are some examples.

The beam 10 is rotated about the axis 90 from the basic posture.
Then, the operation plate 51 is rotated about the third rotation shaft 30 in the direction opposite to the rotation direction of the beam 90 by 90 degrees to maintain the horizontality of the camera C. As a result, the operation plate 5
1 rotates up and down, and by this vertical movement operation, the camera C swings up and down, that is, tilts. From the basic posture, the grip 71 is obliquely supported on either the left or right side, and the operation plate 51 is rotated to maintain the levelness of the camera C. In this state, the beam 10 is swung around the grip 71 or the pin 66. The position of the camera C turns diagonally. For example, when a distant fixed point is taken as the subject, the camera 10 is panned so that the camera C is always facing the subject while swinging the beam 10 from the basic posture to the left or right to rotate the camera C. This operation is performed by the beam 10 in the vertical direction.
Is tilted to tilt the camera C.

C. Effects of Crane Device According to the crane device 1 described above, for example, when photographing in a room such as a house, from an upper subject near a ceiling that is out of reach of the photographer to a subject placed on the floor, or When there is a subject in the front and sides, the camera C position can be moved to the subject by turning or tilting the beam 10.
Further, the angle conversion of the camera C can be remotely operated by operating the operation plate 51. As a result, shooting the subject,
In particular, close-up photography can be performed as desired by the photographer. In other words, small-scale crane photography can be performed by one photographer.

Since the camera position is moved by the beam 10 without directly holding the camera C,
The behavior of the photographer is not directly transmitted to the camera C. Moreover, the center of gravity of the crane device 1 including the camera C is the beam 10
It is located at an arbitrary position on the vertical line passing through the upper supporting point S and is balanced. From these things, even when the moving image is taken by the camera C, the taken image is stable without blurring.

Further, as described above, since the center of gravity of the entire crane apparatus 1 including the camera C is located at an arbitrary position on the vertical line passing through the supporting point S on the beam 10, the camera can be operated with extremely slight force. You can move C,
The burden on the operator is greatly reduced, and the overall balance is always kept constant without being affected by its operation. Moreover, since the longitudinal direction of the operation plate 51 and the optical axis of the camera C are set to be parallel to each other, the longitudinal direction of the operation plate 51 coincides with the direction of the camera C. Therefore, the angle conversion operation of the camera C by the operation plate 51 is directly transmitted, and the operability is improved.

The crane device 1 is attached to one beam 10, an operating unit 11A and an operated unit 11B having the same structure, belts 43 and 44 connecting the units 11A and 11B, and units 11A and 11B. Since the camera C and the operation plate 51 are combined, the structure is simpler and more compact than the conventional one. Therefore, the assembling precision of these is improved, and accordingly, the operation becomes accurate and smooth. Further, it has various advantages such as reduction of manufacturing cost and improvement of transportability and assembling due to weight reduction.

D. Modification of One Embodiment The present invention is not limited to the configuration of the above-mentioned one embodiment, and the following modifications are possible. I. Instead of using the grip 71, the grip 7
The 1 or fork 68 is attached to a support such as a tripod to reduce the burden on the photographer. Alternatively, as shown in FIG. 2A, a screw hole 51a is provided on the lower surface of the operation plate 51, and the screw hole 51a is used to support the screw hole 51a on the support base. in this case,
A weight is attached to the rear of the operation plate 51 so as to balance the weight. B. The beam 10 has a telescopic configuration in which the beam 10 is assembled in a plurality of stages, for example, with two or more rods,
Allows length adjustment. If the beam 10 is configured to be extendable and retractable in this way, the camera C can be brought close to the subject without changing the installation position of the crane device 1, and the photographing range can be arbitrarily changed. C. The operation plate 51 is replaced with a member having another shape that can be rotated. For example, it is preferable to use a rod-shaped member or the like in which the longitudinal direction can be set, because the longitudinal direction is aligned with the direction of the camera C and direct operation is provided. D. The operation unit 11A and the operated unit 11B are merely one embodiment, and their structures are arbitrary due to design changes and the like.

E. Application Example of the Present Invention The above-described one embodiment is an example in which the article is used by converting the directivity direction and is used as a camera, and the present invention is applied to a crane device for photography. It can be applied as a device for supporting an article such as a light (illumination) that is used by directing it in a specific direction. Therefore, for example, a light such as a spotlight can be attached to the stay 52 instead of the camera C and used so that the illumination direction of the light can be freely changed.

[0042]

According to the article supporting apparatus of the present invention, it is needless to say that one photographer can easily perform movement and directional conversion of an article within a relatively narrow range.
A simple structure consisting of a beam, an operating unit and an operated unit of the same structure, a belt connecting these units, a camera attached to each unit, and an operating element improves the assembly accuracy, which leads to an accurate and accurate assembly. A smooth pointing conversion operation is realized. Further, since the structure can be made compact due to the simple structure, the manufacturing cost is reduced and the weight is reduced, so that the transportability and the assembling property are improved.
