Abstract

(57) [Abstract] [Purpose] An object is to provide a television camera having a rotation mechanism with a simple structure. A television camera body 1, a plurality of hooks 2 provided on the bottom of the television camera body, a mounting base 3,
A groove 4 formed on the mounting base and formed in a circumferential shape for fitting with the plurality of hooks and rotatably holding the TV camera body, and a fixing member that acts on the hooks and presses the hooks into the grooves. And a screw 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a television camera covered with a cover having a dome shape or the like, and particularly to a television camera having a rotation mechanism.

[0002]

[Prior art]

 For example, a conventional television camera covered with a dome-shaped cover disclosed in Japanese Patent Application Laid-Open No. 2-42876 (H04N 5/225) has a built-in camera body in order to adjust a horizontal shooting range. A mechanism for rotating the lens block was provided, or a mechanism for rotating the mounting base was provided to rotate the entire camera body.

[0003]

[Problems to be solved by the device]

 In the case of a TV camera with a conventional structure, it is necessary to create a dedicated structure for rotating motion, which is disadvantageous in reducing the size of the main body, and when providing a rotating structure inside the main body. , The structure of the internal block becomes complicated, and the reliability of the connection cable becomes poor, for example.

An object of the present invention is to provide a television camera having a rotation mechanism with a simple structure.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a television camera body, a plurality of hooks provided on the bottom of the television camera body, a mounting base, and a mounting base provided on the mounting base. And a groove formed in a circumferential shape that rotatably holds the television camera body, and a fixing screw that acts on the hook and presses the hook against the groove.

[0006]

[Action]

 When the plurality of hooks are fitted in the circumferential groove and are pressed by the fixing screw, the frictional force between the hook and the groove is increased.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an embodiment according to the present invention. In the figure, reference numeral 1 denotes a TV camera body covered with a dome-shaped cover. At its bottom, there are several hooks 2 having elasticity formed by deforming a part of a metal bottom plate (in the embodiment, (4 places). A groove 4 for fitting the hook 2 is provided on the mounting base 3 over the entire circumference without interruption. The TV camera body 1 can be fitted into the mounting base 3 mounted on a wall or ceiling without being aligned by the hook 2 in the lateral direction, that is, in the direction parallel to the contact surface with the mounting base 3. Yes (arrow 6).

Therefore, since the groove 4 into which the hook 2 is fitted is formed over the entire circumference, the elasticity of the hook 2 prevents the TV camera body 1 and the TV camera body 1 from being disengaged while receiving an appropriate frictional force. It becomes possible to rotate and to perform lateral alignment.

The television camera body 1 is fixed to the mount 3 by pressing the hook 2 with the fixing screw 5 toward the groove 4 side. 2A and 2B are cross-sectional views showing a state in which the television camera body 1 is fixed to the mounting base 3, where FIG. 2A is an overall view and FIG. The same reference numerals are given to the same reference numerals as those in FIG. 1, and the description thereof will be omitted. As is clear from (B), since the fixing screw 5 presses the hook 2, the hook 2 does not come off from the groove 4 even if a large external pressure is applied to the TV camera body 1, and the TV camera body 1 Cannot be rotated with respect to the mount 3.

[0010]

[Effect of device]

 According to the present invention, due to the elastic hook 2 and the groove 4 provided on the entire circumference, a portion having a coupling function up to now has a rotating function without changing the size and structure of the portion. I was able to make it. Therefore, it was possible to absorb the rotation-dedicated mechanism that was provided inside the main body or at the bottom of the main body. As a result, the overall size of the TV camera can be reduced, the number of moving parts inside the main body can be reduced, and the reliability of connection cables and other components has improved.
