【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an embodiment thereof.

In the drawings, 1 is a mounting plate that is directly or indirectly fixed to a ceiling in a room such as a store, 2 is a small monitor TV / camera 3, a small DC motor 4, a reduction mechanism 5 and the like. The casing 2 is a bottom-cylindrical casing, and the casing 2 is provided on the mounting plate 1 so as to hang down so as to be rotatable about a vertical axis. Reference numeral 6 denotes a machine frame fixed to the cover plate 2A of the casing 2, and the TV / camera 3, the electric motor 4, the reduction mechanism 5 and the like are all assembled in the machine frame 6, and these members are It is made of synthetic resin as an opaque body as a whole and is shielded by a casing 2 which is detachably attached to the lid plate 2A from below. Reference numeral 7 is a pivot that hangs from the mounting plate 1 and supports the casing 2 rotatably around a vertical axis.

The television / camera is fixed to a support shaft S rotatably provided on the machine frame 6, and is tilted about a horizontal axis with the rotation of the support shaft S. . Reference numeral 8 denotes an adjustment screw for adjusting the tilt angle of the television / camera 3 which is attached to one of the attachment members 9A and 9B attached to one side of the machine frame 6 so as to be vertically movable. The support shaft S is screwed with the worm gear 10 fixed to the shaft portion that penetrates the machine frame 6 and projects outward, and the adjustment screw 8 is screwed up and down to move the television The tilt angle of the camera 3 can be freely adjusted.

In the illustrated example, the reduction gear mechanism 5 is configured as a reduction gear train. The first-stage gear 11 meshes with the pinion 12 of the small DC motor 4, and the final-stage gear 13 has It is fixed to the shaft end of a gear shaft 14 penetrating through the machine frame 6 and the cover plate 2A of the casing 2 and protruding upward, and meshes with the sun gear 15 provided on the lower surface of the mounting plate 1 as a planetary gear. And constitutes a planetary gear mechanism.

As described above, the bottomed cylindrical casing 2 is formed as an opaque body as a whole, but a part of the peripheral wall 2B of the casing 2 facing the objective lens 3A of the television camera 3 is formed. A translucent window 16 of a required size is provided, and the television / camera 3 can photograph an outside scene through the translucent window 16.

The TV / camera 3 is electrically connected to a monitor TV receiver (not shown) installed at an arbitrary place through a lead wire, while it is connected to an AC power supply together with the small DC motor 4. These are connected to the remote controller 17 having a known constant voltage device (not shown) built therein by means of conductors. The remote controller 17 is provided with a known switch mechanism (not shown) for switching the rotation direction of the electric motor 4 between normal and reverse directions and a switch lever 20 for operating the switch mechanism.

A pair of micro switches 21, 22 are arranged adjacent to each other on the upper surface of the cover plate 2 A of the casing 2 and the casing 2 is rotated clockwise or half-clockwise over a rotation angle of about 360 °. When it is rotated in the direction, the stop projection 23, which selectively contacts the pair of micro switches 21 and 22 to open the circuit between the electric motor 4 and the power source, is hung on the lower surface of the mounting plate 1. It is set up. In the illustrated example, the operation switch lever 20 of the remote controller 17 described above can be swung left and right about this position with the central portion of the mounting portion as the neutral position. In FIG. 1, when the switch lever 20 is swung right, the forward rotation circuit of the electric motor 4 is turned on, and when it is swung left, the reverse rotation circuit of the electric motor 4 is turned on. Is configured.

In the crime prevention surveillance television / camera device configured as described above, when the operation switch lever 20 of the remote controller 17 is operated to close the forward rotation circuit of the electric motor 4, the electric motor 4 is turned on. The forward rotation is started, and its rotation is transmitted to the speed reduction mechanism 5, and the planetary gear 13 operatively connected thereto revolves around the sun gear 15 that is meshed therewith and revolves. As a result, the casing 2 is rotated about its vertical axis at a low speed in a clockwise direction (as viewed from above) with the pivot 7 as a fulcrum. When the casing 2 is rotated in this manner, the small monitor TV / camera 3 built therein is also rotated together with the casing 2. In this case, since the transparent window 16 is provided on the peripheral wall 2B of the casing which faces the objective lens 3A of the television camera 3, the television camera 3 shoots the outside through the transparent window 16. While rotating, it displays the image on the monitor TV receiver. Then, when the switch lever 20 of the controller is returned to its neutral position, the electric motor circuit is opened, the electric motor 4 and the casing 2, and thus also the television camera 3 are stopped from rotating, and the television camera 3 Will continue shooting at that stop position and will continue to send the video to the television receiver.

Next, while the casing 2 is rotating, if the forward rotation circuit of the electric motor 4 is kept closed without returning the switch lever 20 to its neutral position, the casing 2 continues to rotate, When one of the above-mentioned micro switches 21 comes into contact with the stop projection 23, the micro switch 21 is turned off, and at that position, the electric motor 4 and thus also the casing 2 stop rotating. Next, in this state, when the switch lever 20 is operated to close the reverse rotation circuit of the electric motor 4, the electric motor 4 is rotated in the opposite direction this time, and the casing 2 is rotated in the opposite direction over approximately 360 °. Will be moved. In this case, the method of controlling the rotation and stop of the casing 2 is the same as that in the above-mentioned case, and the description thereof will be omitted to avoid repetition. In any case, in the security surveillance TV / camera device according to the present invention, the rotary caging 2 having the built-in TV / camera 3 is fixed to the ceiling of the room as shown in FIG. Since it is set by suspending it from the mounting plate 1, it is possible to perform bird's-eye view photography in which the camera is viewed from all sides with a camera angle that looks down at the object, so the range that can be monitored is much wider than that of a conventionally known one. .
