Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera for photographing a subject and recording the photographed image on a magnetic tape or the like.

[0002]

2. Description of the Related Art Conventionally, a shooting switch operated when shooting with a video camera is provided near the position of a finger of a hand that supports or holds the camera body, and is devised so as to improve operability. There is.

[0003]

By the way, since the shooting switch of the video camera is provided in the state of being exposed in the vicinity of the hand to be gripped as described above, the shooting switch is mistakenly taken when the video camera is handled. Malfunctions of operating the switches are often caused. Therefore, there is a problem that the magnetic tape is wasted. Further, if the camera is in a standby state when the video camera is not shooting, the battery consumption is high, and in this case, the shooting time is shortened. The present invention has been made in view of the above problems, and provides a video camera capable of preventing an erroneous operation of a photographing switch.

[0004]

SUMMARY OF THE INVENTION The present invention is provided with a slide type lid body capable of exposing a key top portion of a photographing switch to an operable state or concealing an inoperable state. The lid is operated at the time of photographing to prevent erroneous operation and reduce battery consumption.

[0005]

The standby state is achieved by the slide type lid which can conceal or expose the key top of the photographing switch, so that it is possible to prevent wasteful consumption of the battery and at the same time prevent erroneous operation. You can also do it.

1 shows an embodiment of a video camera to which the present invention is applied. 2 shows an enlarged plan view of a portion of the switch for photographing and a sectional view taken along the line BB and CC, and FIG. 3 shows a state in which the slide cover is moved. There is. In these figures, 1 is a video camera, 2 is a housing of the video camera 1, and an opening 4 is provided in a grip portion 3. Inside the vicinity of the opening 4, ribs 5 are provided as shown in FIG. Reference numeral 6 denotes a slide cover provided inside the opening 4, and is arranged so as to slide and move on the rib 5 inside the opening 4. As shown in FIGS. 2 and 3, the slide cover 6 has a protrusion 7, an opening 8 formed in the protrusion 7 so that a key top described later is exposed, and both ends of the rib 5. There are provided an elastic projection 9 that is locked by the switch and an operating portion 10 that is a recess for operating the power switch.

Reference numeral 11 denotes a substrate (fixing method is not shown) fixed inside the grip portion 3, a rail 12 for guiding sliding of the slide cover 6, and a photographing switch (hereinafter referred to as a record button). 13), a power switch 15 for turning on a power source such as an electric zoom and an automatic white balance are provided. The record button switch 13 is capped with the key top 14, and the actuator 16 of the power switch 15 is positioned so as to project into the concave portion of the operating portion 10.

Next, the operation of the video camera 1 of the present invention will be described. When shooting with this video camera 1, first, the slide cover 6 in a state in which the recording button 13 is covered with the fingers of the hand holding the video camera 1 as shown in FIG.
2 is pushed up in the direction of arrow A, the projection 9 shown in FIG. 2A receives a pressing force from the rib 5 and is deformed and retracted in the direction of arrow B.
Then, the slide cover 6 is guided by the rail 12 and moves in the arrow A direction. By moving the slide cover 6 in this manner, the key top 14 is exposed in the opening 8,
The actuator 16 is moved upward at the lower end of the operating unit 10 and the power switch 15 is turned on. Therefore, the power of the electric zoom, automatic white balance, etc. is turned on and the standby state of the video camera is obtained.

At this time, since the projection 9 moves to the other end of the rib 5, the projection 9 is projected in the direction of arrow C by its own elastic force and engages with the rib 5. Therefore, the slide cover 6
Is fixed by generating a click feeling, and the record button 13 is positioned below the opening 8, so that the record button 13 can be operated.
The state (b) is reached. Therefore, it is possible to press the key top 14 to operate the recording button 13 and start photographing. When you stop shooting, press the record button 1 again.
It suffices to press 3, and the standby state is maintained at this time.

When the photographing is stopped, if the slide cover 6 is pulled down in the direction of arrow D in the state of FIG. 3, the projection 9 retracts in the direction of arrow B and the slide cover 6 moves in the direction of arrow D as described above. The key top 14 is covered with the slide cover 6, the actuator 16 is moved at the upper end of the operation unit 10, and the power switch 15 is turned off. Therefore, the power supply for the electric zoom, the automatic white balance, etc. is cut off, the standby state is released, and the recording button 13 cannot be pressed in this state.

Further, at this position, the projection 9 moves to one end of the rib 5, and the projection 9 projects in the direction of the arrow C and engages with the rib 5, so that the slide cover 6 is fixed with a click feeling. Button 13 returns to the inoperable state of FIG. Therefore, when the video camera 1 is handled with the slide cover 6 in the state shown in FIG. 2 when the photographing is not performed, the record button 13 is hidden by the slide cover 6, so that the record button 13 is erroneously touched and malfunctions. To stop doing.

Also, an electric zoom driven only at the time of photographing,
The power source for automatic white balance or the like turns on and off the power switch 15 in conjunction with the movement of the slide cover 6, so the problem of forgetting to turn off the power switch 15 after the end of shooting is solved, and as a result, the battery is wasted. The problem of exhaustion also disappears.

FIG. 4 shows a slide cover 6 which constitutes a lid .
Pull out only to show its side sectional view, top view, and perspective view.
The slide cover 6 that constitutes the lid is a base 6
A part of a is used as a protrusion 7, and the inside of the protrusion 7 is a recess.
I am trying to be in between. In addition, an opening is formed on the upper surface of the protrusion 7.
The part 8 is formed.

Then, the slide cover 6 is moved to the exposed position.
When the key top 14 is moved, the opening 8
It is supposed to come from. Also, the slide cover 6
The key top 14 is located when moved to the concealed position
A thick portion 7a is formed on the surface of the protruding portion 7 around the
The portion facing the thick portion 7a of the
The opposing wall portions 7b have almost the same height.

Both sides of the thick portion 7a and both sides of the facing wall portion 7b are
Connected by both sides 7c with slightly recessed center
Therefore, the upper surface of this opening 8 is curved so that a finger can just ride on it.
Will form the surface. Therefore, place your finger in the opening 8.
Then slide the slide cover 6 from the concealed position to the exposed position.
Can be configured to facilitate its movement when riding
You can At the exposed position, the opening 8 is the key top.
Since it will be located on the upper surface of 14,
Press the UP button 14 to operate the record button 13 to enter the recording state.
be able to.

[0016]

As described above, the video camera of the present invention is provided with the lid for setting the photographing switch to the operable state and the inoperable state. Therefore, except when photographing with the video camera. Treats the shooting switch as an inoperable state with the lid, so that the malfunction of the shooting switch can be prevented and the lid can control the video camera to the standby state and the standby state.
There is an advantage that the power consumption of the video camera can be reduced.

[0017] In addition, by forming a protrusion on the surface of the lid,
Make an opening in the protruding part and
The slide cover has a shape that can be put on.
Is easy to move, especially the cover has moved to the exposed position
Sometimes the recording button is exposed from the opening
The effect is that you can immediately enter the recording state.
