Abstract

A video camera recorder having a watertight housing including a housing body, a housing bottom and a closure for closing an opening of the housing. The opening is watertightly closed by a watertight structure including an annular bead formed in the housing and a packing provided to the closure. An electronic view finder is watertightly isolated in a space defined between a partition wall, arranged within the housing, and the housing. A cover is provided between the closure and an electronic equipment, such as a video deck, disposed within the housing, and a packing is arranged between the housing and the cover so that the space surrounded by the cover and the housing is held watertightly. Alternatively, the gap between a portion of a video deck disposed in the housing and a housing is watertightly sealed, the portion of the video deck projecting from the housing the opening. A water absorbent or a water sensor is disposed in a recess formed in the housing.

Claims

1. A video camera recorder of the type comprising:

a housing having opening defining means,

a video camera and a video deck placed within the housing,

a partition wall provided within said housing, and

first and second chambers defined by said housing and said partition wall, said first chamber not being provided with said opening defining means and having said video camera placed therein, said second chamber being provided with said opening defining means and having said video placed therein,

wherein said first and second chambers are watertightly enclosed and are watertightly separated from each other, the partition wall including injection hole defining means for defining a through injection hole in the partition wall, and

wherein a plug member is provided for sealing the injection hole.

2. A video camera recorder comprising:

a housing having an opening,

closure means for watertightly sealing the opening of the housing,

a video camera, an electric view finder, a video deck using a video cassette, operating switches for operating the video deck, signal input/output terminals for said video deck, and a battery, all of which are placed within said housing,

a partition wall provided within said housing, and

first and second chambers, said first chamber being sealed without an opening and having one of the video camera and the electric view finder disposed therein, said second chamber being provided with said opening and having at least one of the video deck, said battery, said video operating switches, and the signal input/output terminals placed therein,

wherein said first and second chambers are watertightly enclosed and are watertightly separated from each other,

wherein the partition wall includes injection hole defining means for defining a through injection hole in the partition wall, and

wherein a plug member is provided for sealing the injection hole.
