Has the function of integrating. The operation of the TV screen rotation device with the above configuration is shown in the figure (
This will be explained below along with FIG. 2).

When the screen 103 is viewed from a slightly shifted position, a button on the remote controller 1 is pressed from that position to cause the transmitter 102 to transmit signals such as radio waves and infrared rays. The detector 104 of the input unit 2 detects the angle α of the signal from the transmitting unit and connects the vertical axis of the center of the screen 103 with the human eye 1.
The angle θ of 01 is calculated by the calculation unit, or the predetermined angle α is directly detected. Since there are various methods for detecting and calculating this input section, the details will be explained separately later, and the explanation will proceed here assuming that the detected and calculated angle is θ. The detected and calculated angle θ is converted by the conversion device 105 into a rotation amount of the motor 108 corresponding to the angle θ so that the vertical axis at the center of the screen 103 coincides with the human eye 101, and is stored in the storage device 106 and rotated. The motor 1 is controlled by the quantity control device 107.
Rotate 08. The amount of rotation may be controlled while being detected by an optical sensor 110 as shown in the figure, or the rotation stop may be controlled based on the rotation time of the motor.
