At this time, each unit base 12a, 15
Since the plurality of mounting screw insertion holes 22 of a, 17a, and 18a are arranged at equal intervals P, as shown in FIG.
These connector unit 12, control unit 15, and accessory unit 17 are oriented at 45 ° and 90 °.
The angle can be freely changed to an angle according to the interval between the plurality of mounting screw insertion holes 22, such as 180 ° or 180 °. Note that FIG.
Then, although the accessory unit 17 is illustrated, the same applies to the connector unit 12 and the control unit 15.

[Shooting style and layout change of each unit]
Next, the shooting style of the portable TV camera 1 and the layout change of each unit will be described.

First, FIG. 6 shows the most standard shooting style in which the portable TV camera 1 is used by being put on the shoulder of the cameraman by the shoulder rest portion 4. At this time, the accessory unit 17 is used as the portable TV camera. 1 is rearranged on the upper side of the back surface 1d, or is newly attached to attach the battery pack 30 and
Another accessory unit 17 is rearranged on the front side of the lower surface 1f of the portable television camera 1 or is newly attached to attach the chest pad 31, the wireless microphone or the like to improve the balance between the front and rear of the portable television camera 1. Then, the control unit 15 is rearranged or newly attached to the left side surface 1b side of the portable television camera 1 so that a third party can easily operate the switches 13 and the volume type 14 from the left side surface 1b side. Furthermore, the connector unit 15 is rearranged downward on the lower side of the rear surface 1d of the portable TV camera 1,
Attach it anew and pull out the connection cable 32 with the camera controller downwards.
It is possible to prevent the connectors 11 from being stressed by the gravity.

Next, FIG. 7 shows a case where the portable television camera 1 is mounted on the tripod 33 and used as a studio camera. At this time, the cameraman operates from the rear of the portable television camera 1.
Therefore, the control unit 15 is rearranged on the back surface 1d of the portable television camera 1 or newly attached to make it easy for the cameraman to operate the switches 13 and the volumes 14. Also, the accessory unit 1
7 is rearranged on the rear side of the upper surface 1e of the portable TV camera 1 or newly attached to attach the 5-inch viewfinder 34 so that the cameraman can easily see the 5-inch viewfinder 34. In addition, the connector unit 12 may be rearranged on the rear side of the lower surface 1f of the portable TV camera 1 or may be newly attached so that the connection cable 32 with the camera controller is directed downward from the portable TV camera 1 near the center of the tripod 33. Thus, when the pan (rotation) or tilt (up / down) operation of the portable television camera 1 is performed, the connection cable 32 thereof can be prevented as much as possible.

When the portable TV camera 1 is used by suspending it from the ceiling of the studio, the accessory unit 17 is attached to the upper surface 1e of the portable TV camera 1.
The portable TV camera 1 can be attached to the camera suspension unit on the ceiling with one touch. Further, the control unit 15 can be rearranged on the lower surface 1f of the portable TV camera 1 or newly attached so that the switches 13 and the volume 14 can be easily operated from below the portable TV camera 1.

As explained in FIG. 5, the reason why the orientations of the connector unit 12, the control unit 15 and the accessory unit 17 can be changed to 45 °, 90 °, 180 °, etc. is as follows. Switch 13 and volume 1 according to the change of the pull-out direction of the angle type connector used and the placement of the cameraman with respect to the portable TV camera 1.
It is possible to improve the convenience such as changing the orientation of 4 or the like and changing the orientation of the 5-inch viewfinder 34.

As described with reference to FIG. 4, by providing two types of units having different structures on the front and back of each unit base 12a, 15a, 17a and 18a,
Two unit bases 12a, 15a, 17a and 18a
The two types of units can be selectively used, and it is convenient to configure a multifunctional unit while reducing the number of parts.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made based on the technical idea of the present invention.

For example, although the above embodiments have been described with respect to the unit device of the portable TV camera, the present invention can be applied to the unit device of the studio TV camera and various other TV cameras.
