Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera platform for mounting and fixing various cameras such as a video camera and a still camera, and more particularly to a video camera which is firmly fixed. Head for a camera provided with a fixed boss for the camera. 2. Description of the Related Art In general, in a camera head of this type, a camera is mounted on the surface of a camera head body, and a fixing screw is screwed into a female screw portion of the camera to be fixed. By the way, in general, for a specific camera such as a video camera, which is larger and heavier than a still camera, a hole is not formed in the specific camera because the fixing screw alone does not provide sufficient support. On the other hand, a boss that fits into this hole is provided on the camera platform so as to suppress front-back, left-right, and right-hand swings around the fixing screw. Conventionally, in camera pan head having such a boss, for example, as shown in FIG. 4, the boss 2,
When a camera other than the specific camera, such as a video camera, is mounted, the camera is unnecessary, so that the camera is provided so as to be able to protrude and retract from the camera platform 1. That is, a bush in which the boss 2 is formed in a columnar shape having a flange 3 at its lower portion, and a recess 4 in which the boss 2 can be immersed and the flange 3 of the boss 2 can slide up and down in the camera platform 1. 5, a coil spring 6 is inserted into the recess 4 to urge the boss 2 in the protruding direction, and the flange 3 is brought into contact with a stopper 7 formed at the opening of the recess. Alternatively, instead of the coil spring 6, a leaf spring may be housed in the bottom of the concave portion 4. When a specific camera such as a video camera is to be mounted, the boss 2 is fitted in a hole of the camera with the boss 2 protruding and used for the purpose, and a camera other than the specific camera such as a still camera is mounted. In some cases, the boss 2 is immersed by the bottom of the camera against the urging force of the spring 6 so as not to hinder the camera. [0005] However, in the above-mentioned conventional camera platform, the boss 2 is provided in the recess 4.
Are required to have a depth corresponding to the stroke, and also require a stopper 7 of the boss 2 and a space for accommodating the spring 6. As described above, the recess 4 must be formed deeply. For this reason, the thickness of the camera platform 1 must be ensured, and there is a problem that there is a problem when the camera platform 1 is formed thin and the camera camera platform is made compact. Further, since the boss 2 slides up and down, a certain clearance 8 is required between the boss 2 and the concave portion 4, so that the boss 2 is loose and the support of the camera becomes uncertain. Was. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to reduce the depth of a concave portion for accommodating a boss so as to make the head thinner and to make the boss rattle. This is to prevent camera from occurring and ensure the support of the camera. [0007] Means for solving the problems described above is achieved by a camera head having a boss on which a camera is mounted and which is engaged with a specific camera. A recess for receiving the boss is formed on the surface of the camera platform body, and a pair of shafts are provided in a projecting manner on the left and right base ends of the boss, and the boss is housed in the recess. The pivot portion is rotatably supported on the side wall of the concave portion so as to be able to be stopped at two positions, that is, the retracted position and the upright position that can be engaged with the specific camera by standing from the concave portion, and the shaft portion is linked to the boss. A rectangular contact portion is formed, and an elastic member is provided on one side wall of the concave portion to support one end and elastically contact the contact portion. The elastic member is provided on the contact portion at the boss storage position and the upright position. It is provided with a contacting flat surface. According to this means, when a specific camera is mounted on the camera platform, the boss is raised to the upright position and engaged with the camera, while when another camera is mounted, the boss is mounted. Is rotated to the storage position. Since the boss is rotated and accommodated, it is only necessary to make the depth of the recess approximately equal to the diameter of the boss, and it is not necessary to form the boss so deeply. Further, the boss is supported by the shaft portion and the shaft portion is pressed by the elastic member, so that rattling is prevented. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A camera head according to an embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show a camera platform according to an embodiment of the present invention. As shown in FIG. 3, the camera platform 10 is applied to a tripod and is supported by support legs 11. The camera platform 10 is provided with a fixing screw 12 that is screwed into a female screw portion formed in the camera, and is fitted in a hole provided in the vicinity of the fixing screw 12 and provided in a specific camera such as a video camera. A boss 13 is provided. The boss 13 is, as shown in FIGS.
The shaft 15 is formed in a columnar shape, and a shaft 15 extending along an axis Q orthogonal to the axis P of the column is formed on the left and right ends of the column. That is, the boss 13 and the shaft portion 15 are basically in a substantially T shape. The base end of the shaft portion 15 is a leaf spring 1 described later.
7 is configured as an abutting portion 14 having a rectangular cross section with which it resiliently contacts. The contact portion 14 has an upper flat portion 14a and a side flat portion 14b orthogonal to the axis P of the cylinder. A recess 16 for accommodating the boss 13 is formed on the surface of the head body as the head 10. The boss 1 is positioned so that the boss 13 can be stopped at two positions, a storage position A where the boss 13 is stored in the recess 16 and an upright position B where the boss 13 can stand up from the recess 16 and engage with the specific camera.
The third shaft 15 is rotatably supported on the side wall of the recess 16. Further, the recess 16 is provided with a pair of leaf springs 17. One end of each leaf spring 17 is inserted into the side wall of the recess 16 and is cantilevered, and the other end is connected to the boss 13.
Is in elastic contact with the contact portion 14. The leaf spring 17 elastically contacts the upper flat surface portion 14a of the contact portion 14 of the boss 13 at the upright position B of the boss 13. Therefore, according to the camera platform of this embodiment, the boss 13 is housed in the concave portion 16 by rotation, so that the depth of the concave portion 16 only needs to be about the diameter of the boss 13. Get better. Therefore, it is not necessary to form the concave portion so deeply as compared with the conventional concave portion which had to be made deeper than the length of the boss 13.
Can be made thin to make the camera head compact. In addition, as shown in FIG. 2, the concave portion 16 has a bottomed shape, but since the boss 13 is supported by the shaft portion 15, the bottom portion can be made open (unbottomed).
In this case, it is possible to make the head more compact by further reducing the thickness of the head body. Further, a camera head according to this embodiment is
When mounting a specific camera such as a video camera, first, the boss 13 is erected at the erected position B. In this case, the contact portion 14 of the boss 13 rotates together with the shaft portion 15, the corner of the contact portion 14 pushes up the leaf spring 17, and then the upper flat portion 14 a contacts the leaf spring 17 at the upright position B. Touch In the upright position B, even if the boss 13 attempts to rotate toward the storage position A, the upper flat portion 14a of the contact portion 14 is pressed by the urging force of the leaf spring 17, so that it is difficult to rotate easily. Next, with the boss 13 upright, the boss 1

The camera is mounted on the camera and the fixing screw 12 is screwed into a female screw of the camera to fix the camera. In this case, boss 1
3 is supported by the shaft portion 15, so that there is no glitch, and since it is pressed by the leaf spring 17, there is no backlash, and the camera is securely fixed without any backlash. On the other hand, when attaching another camera such as a still camera, the boss 13 is lowered to the storage position A, and the fixing screw 12 is screwed in the camera platform 10. In this case, the boss 13 is at the storage position A and does not protrude above the camera platform 10, so that the boss 13 does not become a hindrance and the camera can be easily attached. in this case,
The boss 13 falls down by 90 degrees and is accommodated in the concave portion 16, where the leaf spring 17 elastically contacts the side flat portion 14b. As described above, according to the camera platform of the present invention, the boss is supported so as to be able to stand up and down (rotate). The boss can be housed in the recess only by making the depth about the diameter. Therefore, it is not necessary to form the concave portion so deeply as compared with the related art in which the concave portion is formed deeper than the length of the boss, and accordingly, the camera platform can be made compact by making the camera platform thinner. The boss is supported by the shaft,
Since the contact part of the shaft part is pressed by the elastic member at the upright position,
With a simple configuration, rattling when the camera is fixed is reliably prevented, the camera can be securely mounted, and the contact portion of the boss is pressed by the elastic member even at the storage position in the concave portion. Also, it can be stored without rattling even during storage. [0019]
