Image rotation adaptor

An interchangeable servo control circuit module for use in a television camera is adapted to detachably mount to the television camera body, and is responsive to exterior signals for selectively operating either in a speed servo control mode or in a position servo control mode.

Servo control circuit module for use in a television camera

A servo amplifier for a television camera lens for driving a servomotor to control a zooming, focusing and/or iris control is connected with a power source by way of a current limiter to prevent a voltage drop caused by a rush current. The servo amplifier is composed of a pre-amplifier and a power amplifier, in which the power amplifier is supplied with a power by way of the current limiter. The current limiter is composed of a transistor, a zener diode and resistors, and operates to limit the level of the electric current flowing therethrough.

Servo amplifier for television camera lens

A handy type TV camera or motion picture camera with a grip includes a focal length varying means, a diaphragm aperture varying means and a focus adjusting means. One of these means is electrically controlled by use of a servomotor controlled by a potentiometer. Another of these means is manually controlled by use of a manually operable ring mounted on the camera. The remaining of these means is either electrically or manually controlled. The potentiometer for controlling the servomotor is operated by use of a manually operable control member provided on the grip of the camera. The control member is located on the back of the grip at an upper portion so that it is easily operated with the thumb of the hand which is used to hold the grip. The control member is horizontally movable or rotatable and the grip is extended obliquely downward and forward to further facilitate the operation of the control member.
