D, GND, video terminal section VIDEO, V. GND, various key signal terminal section SERIA from IC circuit 25 for controlling key operation
L, and a function terminal unit RECSTS for instructing a function such as recording or zooming.

As shown in FIG. 4, the pantilter 30 has a video camera 32 mounted on a pedestal 31, and the pedestal 31 tilts in the vertical direction and pans in the horizontal direction. A connection terminal portion 33 to which the connection cord 22 is connected is provided, and the connection terminal portion has a terminal portion corresponding to the connection terminal portion 28.

On the side of the puncher 30 is also provided a signal processing IC circuit 34 for storing each signal, and a motor drive IC circuit 35 which is driven and controlled by the signal processing IC circuit. The motor driving IC circuit 35 selectively drives the tilt driving motor 36 and the panning driving motor 37.

It is connected to 2. The rank signal is also input from the signal processing IC circuit 34 as a key signal, processed, and then output.

The pedestal 31 is rotated in a predetermined direction by driving the drive motor 37 by the panning. In this case, the left and right can be rotated within an angle range of about 140 °, and the rotation angle is set and detected by the optical detecting means 3.
Performed by 8.

That is, as shown in FIG. 5, the optical detecting means 38 comprises a disk 39 of a predetermined size which rotates together with the pedestal 31, and the surface of the disk 39 is black by means such as painting. The angle detecting reflection member 40 having a predetermined size (preferably a square shape) is disposed on the surface at a constant angular interval over the predetermined angle range. The angle intervals are, for example, 10 ° intervals, and the angle detecting reflection members 40 are attached so that the central portions thereof are located across the angle line. The angle range is, for example, 280
°.

Then, when the central reflecting members 40 in the range of 280 ° arranged at equal intervals are set at the left and right central portions to be 0 °, the angle detecting reflecting members 40 at the central portions are shifted 140 ° to the right and left. As a result, the rotation detection range can be set or detected from +10 to + 140 ° on the right side and −10 to −140 ° on the left side as viewed from the center of the disk 39.

Further, in the angle range of 140 ° on one side, for example, in the range of 0 to −140 ° on the left side, a strip-shaped reflecting member 41 is arranged in series inside the angle detecting reflecting member 40 to turn. It is for returning the corner to 0 °. The 0 ° returning reflection member 41 is formed so that one end thereof is located on the line of 0 ° and the other end is located on the line of 140 °. The reflecting members 40 and 41 are made of aluminum foil.

The row of the angle detecting reflection members 40 and 0 °
A first photosensor 42 and a second photosensor 43 are arranged at 0 ° positions respectively corresponding to the rows of the return reflection members 41. Then, each of the photosensors performs angle setting and rotation angle detection by irradiation and reflection of light.

For example, the angle detecting reflection member 40 is used for setting the shake angle of the video camera when the automatic tracking function as the surveillance camera is exerted. In that setting, for example, when a range of 120 ° is to be monitored, it is sufficient to set an angle range of 60 ° on both sides from 0 °, and in this case, a +6 signal and a -6 signal are set. it can.

Further, the shake angle is not always set around the video camera direction of 0 °, so that
For example, if the range is shifted from + to + side by 10 °, by setting the signals of +7 and -5, +10 is shifted to + side by 12 °.
The monitoring in the range of 0 ° can be set. By setting in this way, when the video camera 32 swings to the left or right,
The reflected light from each reflection member 40 is counted, and the rotation is repeated within the set range.

The 0 ° returning reflection member 41 is used to return the camera to the 0 ° position when the camera swing angle is not 0 °, and when the camera is not at the 0 ° position, the reflected light is reflected. It is ready to receive all or no light. Therefore, when it receives a signal for returning to 0 °, it rotates to the right if it is in the light receiving state and rotates to the left if it is not in the light receiving state.
At any position of 0 ° regardless of the direction of rotation, the amount of light received is halved or enters the light receiving state, the position of 0 ° is confirmed, rotation stops, and the position of 0 ° in the semi-light receiving state. Correctly set to. It should be noted that both a battery power source and a commercial power source using an AC adapter can be used for driving the device.

When is turned on, the video camera 32 at a remote position is driven, and the image captured by the video camera is displayed on the display unit 9.

When it is desired to correct the attitude of the video camera while watching the display, the pantilter keys 5 to 8 are selectively pressed to drive the pantilter 30. For example, the tilt can be arbitrarily corrected by pressing the up key 5 or the down key 6, and the panning can be corrected by pressing the right key 7 or the left key 8.

When it is desired to change the angular velocity and the rotation angle in driving the pantilter 30, that is, in operating the camera, when the display key 11 is pressed, the mode of the display unit 9 is changed from the image display to the character generator display, that is, the operation mode. In addition, from the characters in the operation mode displayed on the display unit, select any character with the selection key 12, press the setting key 13 to set, and then the transmission key 1
The signal of the operation mode selected and set by pressing 4 is transmitted to the side of the pantilter 30. The angular velocity and the rotation angle can be set separately or simultaneously and transmitted. Then, when the display key 11 is pressed after the transmission, the display mode is changed to the video display mode.

In the character generator display in the above operation mode, driving and recording of the video camera 32 can be preset. Also in this case, it is possible to perform time setting while viewing the display unit by the above-mentioned operation, confirm, transmit, preset, and automatically drive and record.

Further, while watching the image on the display unit, for example, when it is desired to record, the recording is started by pressing the recording start / stop button 19, and the display lamp 21 is turned on at the same time. When it is desired to stop the recording, the button 19 can be pressed again, and the indicator lamp 21 is also extinguished.
