In addition,, be provided with and the consecutive base portion 24 of the front end of handle part 20c at the leading section of handle 20 as Fig. 1～shown in Figure 5, with the front end of this base portion 24 mutually continuously to the outstanding protuberance 25 in optical axis direction the place ahead.Protuberance 25 is by forwards constituting with the part of the hollow form of side, left and right sides opening, and microphone 26 has been taken in by portion within it.
And then base portion 24 forms greatlyyer, stretches out to the both sides of the direction of intersecting with optical axis direction, and the depressed part of opening upward is being set.On this base portion 24, cooperate integratedly and fixing lid with the action button group 27 who constitutes by a plurality of action buttons.
Be installed in lid on the base portion 24 above, is forming to the high and tilted rearward in its optical axis direction front side.Thus, before the cameraman lifted health with video camera 10 handfuls, its sight line was subvertical angle with respect to the lid face.As the action button group's 27 who is located at this lid concrete content, for example, can enumerate broadcast button, stop button, put button, backrush button, temporary transient stop button, volume by-pass cock, backlight switch etc. soon.
At a side's of this base portion 24 sidepiece, the plane monitor 13 that the LCD, reflection monitor scope etc. of a concrete example representing first display unit constitute is being set by rotational support portion 30 with can carrying out rotational action and rotary movement.Plane monitor 13 is provided with the display surface 13a of display map and is provided with the monitor case 19 of the peristome 19a that exposes described display surface 13a, and monitor case 19 is connected with rotational support portion 30.With the face of the peristome 19a opposition side of this monitor case 19 non-display surface 13b as plane monitor 13.
First rotation section by: constitute in the pair of bearings portion 31,31 that a sidepiece of base portion 24 is spaced apart with predetermined distance and first rotating shaft 33 that is clipped in the bearing plate 32 between the two bearings portion 31 and runs through described pair of bearings portion 31,31 and bearing plate 32.With the direction of the direction of axis line quadrature of first rotating shaft 33 on, plane monitor 13 can rotated at left and right directions S in the angular ranges of 180 degree roughly.Its result, plane monitor 13 can be taked as shown in Figure 1, with the non-display part 13b of display surface 13a opposition side appear at the display closed condition of face side and plane monitor 13 as shown in Figure 2 to the left and right direction rotate 180 degree and make display surface 13a appear at the display opening of face side.
Second rotation section by: bearing plate 32, founding the second not shown rotating shaft that is arranged on this bearing plate 32, constitute with not shown pivoting friction mechanism, this pivoting friction mechanism makes between this second rotating shaft and the 13b of case portion and produces frictional force, thereby plane monitor 13 can be remained on angle arbitrarily.Second rotating shaft extends on the direction with the direction of axis line quadrature of first rotating shaft 33, as shown in Figure 3, plane monitor 13 is being rotated in the angular ranges of 270 degree roughly at fore-and-aft direction T.
Its result, plane monitor 13 can be taked: as shown in Figure 2, display surface 13a rearward rotates 90 degree from the state that appears at upside, through making the shown in Figure 3 state (common photography state) of display surface 13a further rearward rotate 90 degree towards the back side, make non-display surface 13b appear at the state of upside (display surface 13a down) thus, with rotate round about from this state 270 the degree, make the state (auto heterodyne photography state) of display surface 13a towards the front.
In addition, by plane monitor 13 is spent from the upside state direction rotation to the left and right 180 that makes its display surface 13a that non-display surface 13b is occurred, can obtain as shown in Figure 4, plane monitor 13 is overlapped on base portion 24, make display surface 13a appear at the state of upside.In addition, when the display surface 13a of plane monitor 13 was in state (auto heterodyne photography state) towards subject, image is upset automatically by the action of diverter switch.
Like this plane monitor 13 that is supporting by base portion 24 with can changing attitude near, leading section at the grip part of handle 20 20c, expression is being set is being used to operate the record button 35 of a concrete example of action button of image mechanism and the lens button 36 that expression is used for first concrete example of action button of handling lenses device 12.
And then, from state shown in Figure 2, be that about 90 degree are forwards rotated at the center with second rotation section of rotational support portion 30 with plane monitor 13, thus, can make display surface 13a towards subject.In addition, by plane monitor 13 being rotated towards the rear about 90 degree, can make display surface 13a as shown in Figure 3 towards the cameraman.By as shown in Figure 11 with the video camera 10 of such state, the display surface 13a of plane monitor 13 is set on cameraman's the sight line and is supported, can support video camera 10 with comfortable posture, with eyes observe this display surface 13a and to confirm subject on one side photograph on one side.
In the case, if will set distance L 0 length (L1=L0) about equally for from cameraman's eyes to the distance L 1 of display surface 13a with existing video camera shown in Figure 20, connect cameraman's shoulder joint A and the upper arm line AB and the angle [alpha] 1 that forms from the sagging vertical line AV of shoulder joint A of elbow joint B, the angle beta 1 that forms with the forearm line BC that is connected elbow joint B and wrist joint C and upper arm line AB, can be than under the conventional example situation little.
Under this state, because two arms can be near flank supporting video camera 1, so the adversary can not apply big power, and is can be with less power comfortable and support video camera 1 reliably.Therefore, also can reduce fatigue, can make display surface 13a stable and reduce to rock and carry out good photography even photograph for a long time.
In addition, is that center further rearward rotate about 90 degree with plane monitor 13 with second rotation section of rotational support portion 30 from state shown in Figure 3, make display surface 13a down, then with first rotation section be the center with plane monitor 13 to the left and right direction S rotate about 180 degree, as shown in Figure 4, plane monitor 13 is accommodated in base portion 24, thus, display surface 13a can be overlapped ground with action button group 27 towards the top.
Under this state,, therefore, can easily observe display surface 13a because plane monitor 13 is arranged on the center line of case body 11.And because the two ends of plane monitor 13 are outstanding not too many to the side from the side surface part of case body 11, therefore, plane monitor 13 can not be in the way during photography.
The installation attitude of such plane monitor 13 for example, is suitable for as shown in Figure 12, makes video camera 10 finding a view of the front end of electronic viewfinder 21 do not connect order cover 22 with rocking and is pushed against on the chest, fixes the occasion that video camera 10 is photographed.
Under the stationary state of such video camera 10, the cameraman observes the words of the display surface 13a of LCD 13, the angle γ 1 that horizontal line of sight EH when its eyes are observed to horizontal direction, the display surface sight line ED when observing display surface 13a with eyes form can littler than the occasion of conventional example shown in Figure 21 (γ 1＞γ 0).For this reason, the cameraman can reduce the angle of head in the above-below direction swing in order to observe subject and display surface 13a alternately.Therefore, the swing that not only can reduce head alleviates the fatigue of muscle of head, and can reduce the worry of missing the video tape recorder meeting.
And then the installation attitude of plane monitor 13 shown in Figure 4 is suitable for shown in Figure 13ly, holds under the state that handle 20 hangs down video camera 10 at arm F and to photograph the occasion of promptly so-called low angle photography.This state, the place ahead of holding the arm F of handle 20 is disposing the display surface 13a of plane monitor 13 nearby, and simultaneously, this display surface 13a is tilted rearward slightly, therefore, can sight line be dropped on the display surface 13a.Therefore, can use than the situation comfortable posture of conventional example shown in Figure 22 and observe display surface 13a.
And, under the situation of low angle photography, portion is outstanding significantly to the side from the side not have as shown in figure 22 the occasion of conventional example make the plane monitor like that, therefore, arm line AC that connects cameraman's shoulder joint A and wrist joint C and angle θ 1 from the vertical line AV formation of the vertical decline of shoulder joint A can be than little (θ 1＜θ 0) of the prior art.For this reason, even in order not contact with cameraman's leg G and video camera 10 to be left apart from S1 (S1=S0) from leg G, the angle θ 1 of the arm F of this moment also can reduce, and therefore, can reduce the power that arm F is left from leg G.Like this, can alleviate the uncomfortable attitude of feeling heavy easily, hold in both hands video camera 10 pleasantly.
And then, as shown in Figure 9, because record button 35 and lens button 36 are set near the base portion 24 of the grip part of handle 20 20c, therefore, need not change the posture of holding grip part 20c, under this posture, just can operate record button 35 and lens button 36 with thumb.Therefore, not only can reduce and miss the video recording worry on opportunity, and can carry out zoom operation (ズ one ミ Application グ operation) rapidly.
