Abstract

PROBLEM TO BE SOLVED: To improve operability and holdability at the time of use and to improve portability and housability at the time of nonuse by providing the video camera with a hermetic chamber which bulges to the palm side of the hand when gas is filled into a grip part and restores the original shape by shrinking when the gas is discharged. SOLUTION: The outer wall side (the section with which the palm of the hand when the hand clamps the grip part comes into contact) of the hermetic chamber 5 arranged at the grip of a camera body is composed of a sheet material 6 having shrinkability and the inner wall side thereof is composed of a general molded material 7. When a simple pump 8 is manipulated, the hermetic chamber 5 is bulged by filling of the gas into the hermetic chamber and elongation and expansion of the sheet material 6 having the stretchability. Consequently, the grip part is deformed to the shape complying the palm of the user's hand. When the simple pump 8 is further manipulated, the gas is further filled in the hermetic chamber 5 and the sheet material 6 having the stretchability is further bulged. Consequently, the grip part is deformed to the shape complying with the palm of the hand of the user having the large hand such that the user's fingertip comes to the position where the fingertip exactly reaches a trigger button 3 and a zoom button 4.

It is described in (2).

(1) A video camera provided with an airtight chamber in a grip portion, which bulges toward the palm of the hand holding the grip portion when the gas is filled, and collapses and recovers when the gas is discharged.

(2) When the gas is filled, the grip portion is provided with two or more airtight chambers which bulge toward the palm of the hand holding the grip portion, and when the gas is discharged, the airtight chambers are restored. Video camera with adjustable volume.

[0009]

According to the present invention, the grip portion can be adjusted to the shape of the hand by inflating the airtight chamber, so that the video camera can be easily held.

Further, since the swelling of the airtight chamber can be changed by changing the gas filling amount, the size of the grip can be adjusted to the size of the hand of the user, and the zoom button and the trigger button can be used. It is possible to place the finger at a position where the user can easily operate the. Therefore, the operability of the video camera is improved.

When the video camera is not used, by discharging the gas from the airtight chamber, it can be formed into a shape having a small number of projections, so that the portability and the storage efficiency are improved.
