Problems solved by technology

However, in such a camera that transmits power by rotating the motor and gears, there is a problem that the movement is not smooth when the shooting direction is moved in the desired direction.
[0006] In addition, in a camera that has two movable tables, two rotating shafts that are perpendicular to each other, and a mechanism that can set the shooting direction in three dimensions, for example, up, down, left, and right, the load on the circuit is too large depending on the operation control method. become the cause of failure
[0007] In addition, in such a movable table, since the two movable tables can rotate independently around the two rotation axes, they are usually in an unstabl

Abstract

There is provided a turntable drive device (1) capable of returning a position of a movable table to a predetermined direction. An outer movable table (4) is rotatably supported by rotating shafts (2a1 and 2b1), and an inner movable table (5) is rotatably supported by rotating shafts (4a and 4b) provided in the outer movable table (4). The inner movable table (5) is rotated about the rotating shafts (4a and 4b) when a connection plate (30) is linearly moved in the X direction. When a connection plate (40) is linearly moved in the Y direction, the outer movable table (4) is rotated together with the inner movable table (5) about the rotating shafts (2a1 and 2b1), based on the engagement of a rack (40c1) formed in the connection plate (40) with a toothed portion (6b) formed in the outer movable table (4).

Description

technical field [0001] The present invention relates to a rotating table driving device capable of setting the orientation of a fixed camera in multiple directions, and in particular to a rotating table driving device capable of resetting the camera to a preset setting position. Background technique [0002] Patent Document 1 below describes a conventional stationary camera provided with a turntable driving device. The camera is an anti-theft camera device, and the camera is fixed on a first support frame, and the above-mentioned first support frame is rotatably supported on a second support frame. The first support frame and the second support frame are provided with rotation shafts in directions perpendicular to each other, and support the camera rotatably. [0003] Patent Document 1: JP-A-2001-94838 [0004] The camera disclosed in the aforementioned Patent Document 1 is a camera in which a cover member covering the entire camera is attached after adjusting the shooting...
