Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to an optical apparatus to be used in a lens apparatus for television image-taking, a television lens equipped with camera apparatus that is connected to a lens apparatus, etc. 
   2. Description of Related Art 
   An image-taking (camera) apparatus used for television image-taking comprises a main TV camera body and a TV lens, and is used by mounting the TV lens onto the TV camera. Of these components, the TV lens is largely divided into a main lens body part and a drive unit, and the main lens body part has an image-taking optical system and manual rings for manual operation of the image-taking optical system. The drive unit has, housed in the interior thereof, motors, control boards, and a CPU for electromotive drive of the manual rings and is provided on the external surface with various switches and operating members for instructing electromotive control. 
   With regard to the TV lens, though manual zooming and iris operations were carried out in the majority of cases of image-taking in the past, image-taking using electromotive servo has come to be carried out frequently recently, and various functions have been added to the drive unit as well. These include for example, a preset function, with which once an arbitrary zoom position is stored, a motor is driven to the stored zoom position by the pressing of a switch, and a function, by which a user can freely assign this preset function to a switch at a position of choice among the plurality of switches provided on the drive unit. 
   As a means of setting such various functions, a DIP switch is provided inside the drive unit and a cameraperson removes a rubber cap provided on the external surface of the drive unit and sets the DIP switch according to the image-taking circumstances. Such functions that can be set thus enable the scope of image-taking by a cameraperson to be widened and optimal camera work to be realized in accordance with various image-taking circumstances. 
   However, with the conventional TV lens, since the function setting part for the lens is provided inside the drive unit, the setting circumstances of the functions cannot be viewed at a glance, and there is also the troublesomeness of operation of having to remove the rubber cap each time to check the setting state. The act of looking into a small DIP switch provided inside the drive unit is poor in terms of visual recognizability, instant check of the setting state is difficult, and the act of switching the small DIP switch of the operating part with a fingertip is also difficult in terms of operation. The act of operating a DIP switch while checking it is extremely difficult, especially under an environment of inadequate light. Also, in an usage environment unique to TV lenses wherein a single image-taking equipment is shared by a plurality of camerapersons, it is extremely important that it be possible to readily and instantly check the setting circumstances of the cameraperson using the equipment priorly, and such a need could not be answered readily by the conventional TV lens. The enabling of instant check of the setting circumstances of TV lenses, which will become even more complex in the future, and the provision of a setting means which is even better in operability are issues for TV lenses.

In these figures, Reference Numeral  301  denotes a main lens body having an image-taking optical system in its interior and having manual rings for manual operation of focus, zoom, and iris. Reference Numeral  302  denotes a drive unit, which is detachably mounted to the main lens body  301  and has, housed in the interior thereof, motors, control boards, CPU, memory, etc., for electromotive driving of the manual rings. Reference Numeral  303  denotes a seesaw switch, which is operated for servo zoom drive, and when this switch is depressed in the direction of T or in the direction of W in the figure, the zoom is changed in the telephoto direction or the wide direction at a speed corresponding to the amount of depression. Reference Numeral  304  denotes a return switch, which returns signals to the camera in accordance with switch operations. Reference Numeral  401  denotes a VTR switch, which serves as a trigger for recording.

   Though in the present embodiment, just the respective functions shown in  FIG. 121  to  FIG. 134  are customized inside the startup menu, it is obvious that function settings across all tiers may be customized inside the startup menu. 
   By thus providing the TV lens with the display panel  118  for displaying setting lens operation characteristics and the function setting switch  119 , a user is freed of the troublesome operation of the conventional lens, with which a rubber cap provided on the drive unit is removed and then settings are changed by means of a DIP switch inside the drive unit. Also, since functions can be set in accordance with the character information on the display panel, function setting, which is easy to understand and excellent in operability, is enabled, and at the same time, the setting circumstances can be recognized visually even under a dark environment. 
   Furthermore, even in the usage environment unique to TV lenses, wherein a plurality of camerapersons share a single image-taking equipment, function setting can be carried out in accordance with the image-taking circumstances since a plurality of function settings can be stored in the memory, and since the setting circumstances of a cameraperson using the equipment priorly can be checked readily and instantly, the risk of running into an unforeseen problem due to use without check of the setting circumstances of the functions can be avoided. 
   Though with the present embodiment, an example of use of a cross key as the function setting switch was described, any setting switch, such as a jog shuttle switch, etc., may be used as long as it enables functions to be set according to the display flow of the display panel. 
   Furthermore, though with the present embodiment, the display panel and the function setting switch are provided on the drive unit, these may be disposed at any other part of the TV lens that comprises the main lens body and the drive unit. 
   Though a form, in which such a function setting switch and display device are connected separately as accessories to the drive unit via cables, may be considered, since with television image-taking, the image-taking equipment may be set on a tripod or carried on a shoulder depending on the image-taking circumstances and camerapersons desire to take the minimum necessary equipment arrangement in view of maneuverability, it is preferable for the abovementioned function setting switch not to be provided as accessories but to be equipped constantly in the TV lens. Also in comparison to a case where separate units are arranged as accessories, the merit of keeping down the total cost is provided. 
   While preferred embodiments have been described, it is to be understood that modification and variation of the present invention may be made without departing from scope of the following claims.
