Description

  The present invention relates to an operation device for a work body that is interlocked and connected to a double-axis motor. More specifically, the present invention relates to a composite device that swings and tilts a work support base on which a work body such as a surveillance camera is mounted in a turning / non-turning state. The present invention relates to a work body operation apparatus capable of performing an operation.

In general, a work body such as a monitoring camera requires a desired operation control in order to monitor a predetermined range of a monitoring area. For example, as disclosed in Patent Documents 1 and 2, a rotation and a predetermined angle range are set in the neck. There are known multipurpose turntable devices and imaging devices that swing and tilt.
In the thing of patent document 1, a pan head (16) is attached to the rotating disk (11) rotated by a motor (5), and a pan handle (22) is manually operated to this pan head (16). A ceiling plate (24) is connected and fixed so as to be variably adjustable at a horizontal or arbitrary inclination angle, and a surveillance camera (39) is attached thereto, and the rotating disk (11) is rotationally driven by a motor (5). (See FIG. 9).
Moreover, in the thing of patent document 2, the frame engaging part (114) which can be rotated in a horizontal direction is provided in a base (110), and the camera (202) is equipped in the frame engaging part (114). The lower part of the cylindrical camera enclosure frame (200) is swallowed so that it can be tilted in the vertical direction, and a tilt rotation gear (by driving a motor (162) provided in the base (110)) 172) and the panning worm gear shaft (173) driven by the motor (160), the camera surrounding frame (200) is tilted in the vertical direction and the frame engaging portion (114) in the horizontal direction, respectively. It is comprised so that rotation operation can be performed (refer FIG. 9, FIG. 10).

However, although the thing of patent document 1 can selectively mount | wear with workpiece | work bodies, such as a monitoring camera and a light projector, there exists a fault that the combined operation | movement of rotation and a tilt cannot be performed since angle adjustment is manual. In addition, in Patent Document 2, although a combined operation of rotation and tilt can be performed, a cylindrical frame casing (210) for swinging and tilting the camera surrounding frame (200) is frame-engaged. Since the feed gear (220) is formed in the lower surface area of the outer periphery swallowed in the part (114), the two independent motors are used for swinging and rotating. It must be constructed as an operating system and must be integrated and assembled with a special structure, resulting in a complicated structure of the device itself, an increase in the number of parts, and a high manufacturing cost. In addition, since the tilting arc angle range is about 45 degrees, it must be accompanied by a turning motion when the monitoring target moves from one side to the other side, and the shooting is interrupted and becomes an intermittent state continuously. In addition, there are disadvantages such as being unable to shoot in the state, and there is a disadvantage that the wiring and piping of the drive source become complicated, and because it is dedicated, it can not be replaced and installed, so it is versatile There is a problem of lacking.
