Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a video camera in which a grip integrally formed with a finder is rotatably attached to a side surface of a main body case.

[Conventional technology]

Among recent compact video cameras, there is a video camera in which a grip is rotatably attached to a side surface of a camera body and a finder is integrally incorporated in the grip. According to this, for example, when shooting at a low angle, by setting the rear end of the grip upward depending on the shooting posture, not only can the camera be held easily, but also the viewfinder image can be easily observed in a comfortable posture. Was very convenient.

[Problems to be solved by the device]

However, if the finder is integrated into the grip as described above, the grip tends to become large in the thickness direction,
The width of the entire video camera becomes large.
In addition, a stopper is required between the camera body and the grip in order to regulate the rotation end of the rotatable grip. However, in the case where this stopper is provided near the rotation center axis of the grip, Requires considerable strength, which is disadvantageous in terms of structure and cost.

[Purpose of device]

The present invention was made in consideration of the technical background as described above, and the entire structure is compact while using a grip with a built-in viewfinder, and the stopper structure for regulating the turning end of the grip is also simplified. It is an object of the present invention to provide a video camera which is advantageous in terms of cost.

[Means for solving problems]

In order to achieve the above object, the present invention has a mechanism in which a grip incorporating a finder is rotatably provided on a side surface, and a part of a mechanism incorporated in a camera body is projected from the side surface apart from a rotation center of the grip. The grip is provided with a locking portion that engages with a cover formed on the camera body to protect the protruding part or the part, and restricts the range of rotation of the grip.

[Action]

According to the above configuration, since the camera body is formed by projecting a part of the mechanism from the side surface, it is possible to reduce the thickness of the camera body. Since the grip integrally provided with the finder is rotatably attached to the portion where the thickness is reduced, the lateral size of the video camera is not increased.
Also, the locking portion provided at a position away from the center of rotation is locked to a part of the mechanism or the cover with a small force,
The range of rotation of the grip part is restricted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

〔Example〕

In FIG. 2 showing an embodiment of the present invention, a main body portion 3 of a video camera 2 is provided with a photographing lens 4 on the front surface thereof and a rotatable grip portion 5 on one side surface thereof. Further, a cassette loading door 6 that opens and closes when the video cassette is attached and detached is provided on the upper portion of the main body 3. The photographing lens 4 is moved along the photographing optical axis 7 by a well-known autofocus device, and is automatically focused.

A band 8 is provided on a side surface of the grip portion 5, a seesaw knob 9 is provided on an upper portion thereof, and a recording button 10 and an L button are provided on a front side thereof.
Lock knobs 12 fitted in the V-shaped slots 11 are provided respectively.

The finder unit 15 has a small CRT monitor 1 for displaying a finder image obtained by the taking lens 4.
6 is incorporated, and a finder image can be observed through an eyepiece lens 17 formed of a convex lens. In addition,
This finder unit 15 is an action finder, and even if it is observed at a position about 50 cm away from the eyecup 18, the entire viewfinder image can be observed without omission. Reference numeral 19 indicates the finder optical axis.

In FIG. 3 showing the main part of the grip part 5 in an exploded manner, the main body part 3 is integrally formed with a cylindrical mount 26 in which a cylindrical body 25 is provided in the central part. The mount 26 has a cord lead-in port 27 and three bosses 28. In addition, around the mount 26, for example, the chassis 2 that holds the imaging circuit unit in the main body 3 is provided.
9 projects to the grip portion 5 side. Although the chassis 29 is projected from the side surface of the main body 3 in this embodiment,
A part of the mechanism built in the main body 3 may be projected from the side surface.

A grip base 32 in which the finder portion 15 is integrally incorporated is rotatably mounted on the mount 26.
For this reason, the grip base 32 is integrally formed with the gap portion 33, and as shown in FIG.
It is fitted to the outer circumference of 6. An opening 35 is formed in the cap portion 33, and a rim 36 is provided so as to surround the opening 35. Step portions 37 and 38 are formed on the cap portion 33, and the step portions 37 and 38 contact the chassis 29 to prevent the grip portion 5 from rotating.

The three bosses 28 planted in the mount 26 are inserted through the openings 35. The bosses 28 have an opening 39 formed in the center and a rubber ring 40 on the outer periphery.
The reinforcing plate 41 to which is fixed is fixed by the screw 42. Since the outer diameter of the reinforcing plate 41 is larger than the outer diameter of the rim 36, by fixing the reinforcing plate 41 to the boss 28, the grip base 32 does not fall off the mount 26.
A cutout portion is provided in a part of the rim 36, and the cutout portion has a withdrawal cord 43 from the operation detection circuit of the seesaw knob 9, a withdrawal cord 44 from the ON / OFF detection circuit of the recording button 10, and Has a withdrawal cord 45 from the CRT monitor 16.

A leaf spring 51 is attached to the boss 50 of the cap portion 33. The leaf spring 51 has a semi-circular shape as shown in the drawing, and several projections 52 are formed inside the leaf spring 51, and a click plate 53 is integrally formed. When the finder optical axis 19 and the photographing optical axis 7 are parallel to each other at the tip of the click plate 53, the click hole 5 formed in the reinforcing plate 41.
Fit in 4. A connecting member 55 is attached to the free end of the leaf spring 51, and the lock knob 12 is connected to the connecting member 55 through the slot 11.

The operation of the thus constructed video camera of the present invention will be described. In FIG. 1, when a finger is passed under the band 8 and the grip portion 5 is grasped with the right hand, the recording button 10 and the lock knob 12 are thumbs, and the seesaw knob 9 is the index finger or the middle finger as shown in FIG. Operation becomes possible.

When the lock knob 12 is lowered along the slot 11 with the thumb and moved to the lock release position, the leaf spring 51 separates from the rubber ring 40, and thus the grip base 32 can be rotated with respect to the mount 26. When a small child is the subject, the main body 3 is kept horizontal and the grip 5 is rotated clockwise, as shown in FIG. Then, when the lock knob 12 is raised in the slot 11 and moved to the lock position, the leaf spring 51 is wound around the rubber ring 40, the frictional force is increased, the rotation of the grip base 32 is prohibited, and a state in which photographing is easy is performed. The grip part 5 is fixed to the main body part 3.

When the grip portion 5 rotates clockwise and the chassis 29 and the step portion 37 come into contact with each other as shown in FIG. 1, the grip portion 5 is prevented from rotating. Further, when the grip portion 5 rotates counterclockwise, the chassis 29 and the step portion 37 come into contact with each other to prevent the rotation.

At the time of the rotation, the cords 43 to 45 are pulled,
Although it comes to wind around the outer peripheral surface of the tubular body 25, in FIG. 1 showing the end of the rotation, since the cords 43 to 45 are not in the extended state, an unreasonable force such that the connecting portion is peeled off is generated. It does not affect 43 to 45.

In parallel with the above operation, distance measurement is performed by the autofocus device. When the record button 10 is operated, the video image taken by the taking lens 4 is recorded in the video cassette loaded from the cassette loading door 6.

Although the present invention has been described above according to the illustrated embodiment, the present invention is not limited to the electronic finder using the CRT monitor, but can be applied to the one using the optical finder.

[Effect of device]

As described above, in the video camera of the present invention, a part of the mechanism built in the camera body, which is rotatably provided on the side with a grip incorporating a finder, is separated from the center of rotation of the grip. Since the grip is provided with a locking portion that projects from the side surface and engages a cover formed on the camera body to protect the projected part or this part, and restricts the range of rotation of the grip, the camera The main body can be formed to have a small thickness, and since the grip is attached to the reduced thickness portion, the lateral size of the video camera can be reduced. Further, since a part of the mechanism or the cover is used as a part of the stopper, it is possible to save parts and reduce the manufacturing cost.
