摘要:
In a focus demand connected to a lens unit of a television camera, a joystick for designating the direction of movement of an AF area is disposed. A direction change switch for reversing the direction of movement of the AF area with respect to the direction of operation of the joystick is also provided. The focus demand is reversed in vertical and horizontal directions between the case of being mounted to be operated by the right hand and the case of being mounted to be operated by the left hand.

A support stage for a prompter has a bi-divisional structure comprising a first support stage on which an LCD and a semitransparent mirror are supported and a second support stage on which an ENG camera is supported. Because the first support stage and the second support stage are constructed in the manner as to be capable of overlapping with each other by a slide mechanism, the support stage can be compact in size and can have a better weight balance; hence the support stage is easy to carry.

A motor for a focus fine tuning lens is attached to the side of a lens barrel. The motor connects to a lens holding frame of the fine tuning lens via a belt, so that the backlash can be prevented. Because the motor and a belt transmission mechanism are accommodated by a drive unit, the existing drive unit can be used without changing its size and form.

A helicoid is formed at the outer periphery of the front of a body fixing lens barrel, and a helicoid is formed at the inner periphery of the back of the focusing lens barrel in such a manner that these two helicoids can be engaged with each other. A movable focusing lens group is held by the front of the focusing lens barrel so that the helicoid can be pushed to one side and the inaccurateness of the focus can be reduced. A lens hood is attached to a fixed focus lens frame fixed to a focus fixing lens barrel, which is different from the body fixing lens barrel. Thereby, even if the focus fixing lens barrel is deformed by the force generated by the attachment, the deformation does not warp the helicoid.

The present inention proides a focus control apparatus for a television camera comprising a focus adjusting portion for manual focus adjustment of the television camera, an indicating member for use to specify an area desired to be brought into focus within a range of a camera image being picked up by the television camera, an area display deice which displays position of the area specified with the indicating member, on a camera screen and a switch which outputs a command signal to auto-focus on a subject in the area specified with the indicating member, wherein the indicating member and the switch are positioned such that the indicating member and the switch can be operated simultaneously with the focus adjusting portion by the same hand.
摘要:
Two cam pins of the variable magnification lens group and the aberration correction lens group are guided by two side walls of one cam groove. Thus, two cam grooves can deal with three movable lens groups, and there is no need to provide three cam grooves. Consequently, the cam cylinder can be short, and thereby the zoom lens apparatus can be compact. A spring applies force to the two cam pins to separate from one another, so that the cam pins can be pressed against the side walls.

The present invention is a prompter for TV camera allowing it to easily mount a half mirror on a manuscript display with an image memory. The apparatus comprises a support plate swingably supporting the half mirror, operating knobs for securing the half mirror at its operating position and retracted position, and a light shield for shielding the half mirror therearound when the half mirror is positioned in front of the lens assembly, and being foldable. The support plate is mounted on the display unit by mating the half hinges, or by coupling with magnets. When the half mirror is inclined by 45.degree. to its operating position, the image of manuscript is displayed on the half mirror. In retracting, the half mirror is moved to the retracted position and the light shield can be folded.
