Abstract
Abstract A portable television camera is equipped with an additional electronic view finder having an eyepiece arranged to project outside the camera body in a direction perpendicular to a longitudinal center axis of the camera body. The electronic view finder is pivotally mounted on the top of the camera body to be horizontally rotated causing the projecting eyepiece to be positioned above the the top of the camera body when unused. In one a mounting member having two L-shaped arms is employed for the attachment of the electronic view finder, utilizing a threaded hole at the bottom of the camera body which is not originally designed to carry an electronic view finder thereon. The electronic view finder may be used with or without a shouldering aid which can be attached to the bottom of the camera body.

Total Claims: 16
Claim 1
Independent Claim
279 words
A television camera assembly comprising: (a) a television camera body having a top and two sides which are substantially parallel to a camera axis passing through a lens attached to said television camera body and a subject to be viewed by said television camera; (b) an electronic view finder having a body mounted on or above the top of said television camera body, an eyepiece portion attached to one side of a body of said electronic view finder; and (c) means for pivotally mounting said body of said electronic view finder on or above the top of said television camera body so that said electronic view finder can be rotated between a position of use and a position of non-use through substantially 90 degrees in a plane parallel to the camera axis and perpendicular to said two sides of said television camera body, the electronic view finder including the eyepiece portion having a length less than its width in the direction of the camera axis, when in said position of use, said eyepiece portion projecting from one side of said television camera body when said electronic view finder body is rotated to said position of use whereby a user can readily look into said eyepiece portion when using said television camera assembly, and said eyepiece portion being positioned above and substantially contiguous with said television camera body when said electronic view finder body is rotated to the position of non-use whereby said eyepiece portion does not project substantially beyond the sides of said television camera body when viewed from the top, thereby reducing the effective width of said television camera assembly when altering it to the position of non-use.
