Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small pan head device, and more particularly to a structure for controlling a pan head for directing a photographing camera or the like in an arbitrary direction by remote control.

[0002]

2. Description of the Related Art ITV (Industrial Television), C
In shooting with a TV camera in CTV (Closed-Circuit Television), TV broadcasting, etc., the shooting camera is remotely operated in order to properly display a target subject or to capture an image of a predetermined area. A pan head device is used to change the direction of the photographing camera.

In this pan head device, two drive shafts orthogonal to the pan head are arranged, and a photographing camera or a support wall can be connected to a support disk connected to the drive shafts.
A control unit is connected to the platform with a cable. Therefore, when the two drive shafts are rotated based on the operation of the control unit, the photographing camera is driven to pan (horizontal direction) and tilt (vertical direction), whereby the photographing camera can be set in a desired area. it can.

[0004]

By the way, the above-mentioned conventional pan head is relatively large (it is about 10 cm in length and width for ITV) and is heavy, but in recent years, the size of the photographing camera is small. Since the reduction in size, weight, and simplification are progressing, the applicant of the present application proposes downsizing of the platform in order to cope with this.

In such a small platform, it is conceivable that the platform is controlled not only by the control unit cable-connected to the platform as described above, but also by operating the remote controller. According to this remote controller control, there is an advantage that it is not necessary to connect a cable, and there is no limitation of movement by connecting the cable. Therefore, it would be convenient if both the control of the control unit and the remote control can be performed.

However, when both the member connected to the control unit and the member connected to the remote controller control are provided, the structure is duplicated and there is a waste of cost. Also, in the case of remote control, it is necessary to install the battery as a power source so that it is integrated with the platform, so the weight of the platform itself becomes heavy and unnecessary load is applied to the motor when controlling from the control unit. Will be costly.

The present invention has been made in view of the above problems, and an object thereof is that the control by a cable-connected control section and the remote control can be selected, and the structure of the entire apparatus is simplified and is easy to use. It is to provide a good compact pan head device.

[0008]

In order to achieve the above object, the present invention provides a small pan head having two drive shafts orthogonal to each other with one connector member for connecting a cable to a control unit, and a remote controller. The receiver unit that receives a signal transmitted from the operation unit is provided with the other connector member that connects to one connector member of the platform, and this receiver unit is configured to be connectable so as to be integrated with the platform. It is characterized in that control by the control unit and control by a remote controller can be selectively performed.

[0009]

According to the above construction, when the control of the control section is selected, the cable from the control section can be connected to one connector on the camera platform side by the other connector while the receiver unit is not attached. The operation of the control unit drives the tripod head. On the other hand, when the remote controller control is selected, the receiver unit may be integrally mounted and fixed by the mounting member while the other connector of the receiver unit is connected to the one connector, and the platform is controlled by the remote controller operation. . Therefore, the control of the control unit and the remote control are selectively switched.
