Abstract
Abstract A camera includes a video camera unit to shoot a movie image and a still camera unit to shoot a still image so as to permit the movie and still images to be shot at the same time. The still camera unit has a unit to wind up a film, and a driving force is imparted to the windup unit by means of two rotational force impart units respectively having smooth surfaces to contact with each other. Consequently, when a still image is shot while movie image shooting is taking place, noise produced by winding up the film can be minimized.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
A camera for shooting movie and still images comprising: a video camera unit including an imaging optical system for imaging an object, said imaging optical system outputting signals representative of a movie image of the object which are recorded on a magnetic tape; and a still camera unit for recording a still image of said object on a photographic film, said still camera unit including, windup means for winding up the film, motor drive means for supplying a driving force causing said windup means to wind up the film and driving force imparting means for imparting the driving force from said motor drive means to said windup means, said driving force imparting means including at least two rotational force imparting members each having smooth surfaces contacting each other so as to impart a rotational force to said winding means through a contact between said smooth surfaces.
Claim 2
Dependent Claim
146 words
A camera for shooting movie and still images comprising: a video camera unit including an imaging optical system for imaging an object, said imaging optical system outputting signals representative of a movie image of the object which are recorded on a magnetic tape; and a still camera unit for recording a still image of said object on a photographic film, said still camera unit including, windup means for winding up the film, motor drive means for supplying a driving force causing said windup means to wind up the film and driving force imparting means for imparting the driving force from said motor drive means to said windup means, said driving force imparting means including at least two rotational force imparting members each having smooth surfaces contacting each other so as to impart a rotational force to said winding means through a contact between said smooth surfaces.
Claim 3
Dependent Claim
23 words
A camera in accordance with claim 1, wherein said video camera unit and said still camera unit are arranged in a unitary housing.
Claim 4
Dependent Claim
37 words
A camera in accordance with claim 1, wherein said video camera unit and said still camera unit are respectively arranged in independent cabinets, said still camera unit cabinet being detachably mounted on said video camera unit cabinet.
Claim 5
Dependent Claim
20 words
A camera in accordance with claim 3, wherein said motor drive means is disposed in said video camera unit cabinet.
Claim 6
Dependent Claim
35 words
A camera in accordance with claim 1, wherein said driving force imparting means includes a plurality of rims having smooth surfaces, the surfaces of adjacent rims contacting each other to impart said rotational force therebetween.
Claim 7
Dependent Claim
43 words
A camera in accordance with claim 1, wherein said driving force imparting means includes a plurality of pulleys and a belt applied to said pulley, said belt also connected to said motor drive means to impart said driving force to said pulleys therefrom.
Claim 8
Dependent Claim
161 words
A camera for shooting both movie and still images of an object simutaneously, comprising: a video camera unit for recording said movie images and associated soundtrack on a magnetic recording medium; and a still camera unit for recording said still images on a photographic recording medium, said still camera unit including, advance means for advancing said photographic medium upon the recording of a still image thereon, motor drive means for supplying a driving force to drive said advance means, and driving force imparting means for imparting said driving force from said motor drive means to said advance means; said driving force imparting means including at least two rotational members having smooth surfaces contacting each other so as to impart said driving force from said motor drive means to said advance means with a minimum of noise, thereby enabling said still images to be recorded during the recording of said movie images and associated soundtrack without introducing undesired noise onto said soundtrack.
Claim 9
Dependent Claim
161 words
A camera for shooting both movie and still images of an object simutaneously, comprising: a video camera unit for recording said movie images and associated soundtrack on a magnetic recording medium; and a still camera unit for recording said still images on a photographic recording medium, said still camera unit including, advance means for advancing said photographic medium upon the recording of a still image thereon, motor drive means for supplying a driving force to drive said advance means, and driving force imparting means for imparting said driving force from said motor drive means to said advance means; said driving force imparting means including at least two rotational members having smooth surfaces contacting each other so as to impart said driving force from said motor drive means to said advance means with a minimum of noise, thereby enabling said still images to be recorded during the recording of said movie images and associated soundtrack without introducing undesired noise onto said soundtrack.
Claim 10
Dependent Claim
