Abstract
An electrically driven zoom lens camera includes a zoom lens barrel having a cam ring, a motor which rotates the cam ring through a gear train including a terminal gear connected to the cam ring, and a pair of component accommodating spaces which are defined by and between a cylindrical portion of the zoom lens barrel and upper and lower wall surfaces of a camera body, so that the motor and the terminal gear of the gear train are located in respective component accommodating spaces.
Claims30
An electrically driven zoom lens camera comprising:
- a zoom lens barrel having a rotatable driving member and a variable lens group which is moved in an optical axis direction by rotation of said driving member,
- a camera body having an aperture which defines a size of a picture to be taken, upper and lower wall surfaces in a elevational view, and a cylindrical portion in which said zoom lens barrel is accommodated, said aperture and said cylindrical portion being arranged along the optical axis direction, and a plurality of component accommodating chambers which are each defined by and between said cylindrical portion and one of said upper and lower wall surfaces of said camera body, said cylindrical portion extending between said upper and lower wall surfaces, a diameter of said cylindrical portion substantially perpendicular to said wall surfaces corresponding to a distance between said wall surfaces, said component accommodating chambers being offset with respect to said diameter, and
- a motor which rotates said rotatable driving member through a gear train, said motor and a terminal gear of said gear train are each housed in individual ones of said component accommodating chambers.
An electrically driven zoom lens camera, wherein a zoom lens barrel of said zoom lens camera has a rotatable driving member and a variable lens group which is moved in an optical axis direction by rotation of said rotatable drive member, and wherein a camera body of said zoom lens camera has an aperture which defines a picture size on an image area of a film and is located on an optical axis of said zoom lens barrel, a motor which rotates said rotatable driving member through a gear train, and a cylindrical portion in which said lens barrel is accommodated, said motor housed in one of a pair of component accommodating chambers which are defined by and between said cylindrical portion and one of said upper and lower wall surfaces of said camera body in a front elevational view, a diameter of said cylindrical portion substantially perpendicular to said wall surfaces corresponding to a distance between said wall surfaces, said component accommodating chambers being offset from said diameter.
An electrically driven zoom lens camera comprising:
- a zoom lens barrel having a rotatable driving member provided with a peripheral gear, so that a zooming operation is carried out by rotation of said rotatable driving member,
- a camera body having a cylindrical portion in which said zoom lens barrel is accommodated, said cylindrical portion having an opening formed thereon in which a drive pinion is provided to engage with said rotatable driving member of said zoom lens barrel,
- said cylindrical portion having a diameter substantially perpendicular to said wall surfaces, said diameter corresponding to a distance between upper and lower camera body wall surfaces, said pinion being contained within a space defined between said wall surfaces, and
- a light intercepting plate which supports said drive pinion and which is arranged on an outside of said cylindrical portion in a manner which prevents harmful light from reaching a film frame defining aperture.
