Output from

The automatic pan head 50 includes a monitor television 58.
Can be connected. The monitor TV 58 is detachable.
The video camera 5 by the existing image signal output code 59
Connected to 1. In addition, the automatic head 50 and the video camera 5
1 is connected by a signal transmission cord 64 . This co
The mode 64 is detachable from the automatic camera platform 50 and the video camera 51, and transmits a signal from the automatic camera platform 50 to the video camera 51.

The remote control apparatus constructed as described above, after mounting the video camera 51 to the automatic camera platform 50, co for signal transmission and automatic pan head 50 and the video camera 51
The connection is made with the mode 64 . Next, an external optical receiver 54 is provided at one end.
Is connected to the automatic camera platform 50, and the image signal output code 59, to which the monitor television 58 is connected at one end, is connected to the video camera 51. Then, the external optical receiver 54 and the monitor television 58 electrically connected to the automatic head 50 and the video camera 51 by the cords 53 and 59, respectively, are arranged at a location away from the automatic head 50.

The photographer of the video camera 51 operates the controller 55 to transmit a light control signal to the external light receiver 54. First, when the power key 56e of the controller 55 is turned on, an optical control signal for starting operation is transmitted from the optical transmitter 57 provided inside the controller 55 to the external optical receiver 54. The video camera 51 enters the table 50, and is transmitted to the video camera 51 via the code 64 , and the video camera 51 shifts to a shooting preparation state. As a result, the video camera 51 enters the observation state in the finder, and the image signal is
9 to the monitor television 58,
8 is displayed on the screen.

The operator of the controller 55 operates the operation unit 56 while watching the screen of the monitor television 58. For example, when the key 56a is pressed, the controller 55 is pressed.
An optical control signal for rotating the automatic head 50 in the left direction is output from the optical transmission unit 57, and the control signal is received by the external optical receiver 54, and from the code 53, the automatic head 50 is transmitted. Then, the horizontal rotation drive mechanism operates to rotate the horizontal rotation unit 50b of the automatic head 50 to the left.

The video camera 51 mounted is rotated with the rotation of the automatic camera platform 50. The operator of the controller 55 checks the image on the monitor television 58 which changes with the rotation of the video camera 51. When the key is pressed and the video camera 51 captures the subject, the key is pressed.
The pressing operation of 56a is released to stop the rotation of the automatic pan head 50.

When the video camera 51 is to be adjusted in the vertical direction, for example, when the key 56c is pressed, an optical controller for rotating the automatic camera platform 50 upward from the optical transmitter 57 of the controller 55 is used. A control signal is output, and the control signal is received by the external optical receiver 54 and taken into the automatic head 50 via the code 53. The vertical rotation drive mechanism of the automatic head 50 is operated by the input of the control signal, and the vertical rotation unit 50c of the automatic head 50 rotates upward.

The operator proceeds with the operation while checking the shooting direction of the video camera 51 on the screen of the monitor television 58, and releases the pressing operation of the key 56c when the video camera 51 captures the subject to release the automatic camera platform 50. To stop rotation.

Similarly, when the key 56b is pressed, the horizontal rotating part 50b of the automatic head 50 rotates clockwise, and when the key 56d is pressed, the vertical rotating part 50c of the automatic head 50 is lowered. Rotate in the direction. In this manner, the automatic camera platform 50 is rotated in the up, down, left, and right directions by remote control so that the shooting direction of the mounted video camera 51 is directed to the subject.

After the video camera 51 is pointed at the subject, the photographing key 56f of the operation unit 56 is turned on.
A light control signal for starting photographing is transmitted from the light transmitting unit 57, and the light control signal is received by the external light receiver 54, enters the automatic camera platform 50 from the code 53, and is transmitted to the video camera 51 by the code 64. Then, shooting by the video camera 51 is started.

When the photographing is to be ended, the key 56f is turned off to terminate the photographing of the video camera 51 by the same remote control as described above. Note that the monitor television 58 described above does not need to be provided particularly when the photographing range of the video camera 51 is determined visually.

FIG. 2 shows a second embodiment of the present invention and is a simplified diagram showing a remote control state of a video camera. In this embodiment, the automatic pan head 50 is remote-controlled by using a relay transmitting tool including an optical transmitting section 61 provided at one end of the cord 60 and an external optical receiving section 62 provided at the other end of the cord 60. It is configured to control. In addition, relay
The transmitter is provided with an amplifier 63, and furthermore, an optical transmitter
