Abstract
Abstract A photographic camera has a housing, a viewfinder, an objective displaceable between extended and retracted positions relative to the housing, a device for displacing the objective between the extended and retracted positions, a film transporting device, a film take-up spool, an electric motor rotatable in two opposite directions and arranged so that when the electric motor rotates in one of the directions it is coupled with the objective displacing device, and when the motor rotates in the other of the directions it is coupled with the film transporting device and the film take-up spool, a switching element for reversing the electric motor, and a locking device for the film take-up spool, coupled with the switching element so that when the electric motor is switched for rotation in the one direction for displacing the objective and is coupled with the objective displacing device the film take-up spool is locked against rotation, and when the electric motor is reversed and uncoupled the film take-up spool is released.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
162 words
A photographic camera, comprising a housing; a viewfinder; an objective displaceable between extended and retracted positions relative to said housing; means for displacing said objective between said extended and retracted positions; film transporting means; and film take-up spool; an electric motor rotatable in two opposite directions and arranged so that when said electric motor rotates in one of said directions it is coupled with said objective displacing means and when said electric motor rotates in the other of said directions it is coupled with said film transporting means and said film take-up spool; switching means for reversing said electric motor; and locking means for said film take-up spool, coupled with said switching means so that when said electric motor is switched for rotation in said one direction for displacing said objective and is coupled with said objective displacing means said film take-up spool is locked against rotation, and when said electric motor is reversed and uncoupled said film take-up spool is released.
Claim 2
Dependent Claim
162 words
A photographic camera, comprising a housing; a viewfinder; an objective displaceable between extended and retracted positions relative to said housing; means for displacing said objective between said extended and retracted positions; film transporting means; and film take-up spool; an electric motor rotatable in two opposite directions and arranged so that when said electric motor rotates in one of said directions it is coupled with said objective displacing means and when said electric motor rotates in the other of said directions it is coupled with said film transporting means and said film take-up spool; switching means for reversing said electric motor; and locking means for said film take-up spool, coupled with said switching means so that when said electric motor is switched for rotation in said one direction for displacing said objective and is coupled with said objective displacing means said film take-up spool is locked against rotation, and when said electric motor is reversed and uncoupled said film take-up spool is released.
Claim 3
Dependent Claim
50 words
A photographic camera as defined in claim 1; and further comprising means for coupling said electric motor with said objective displacing means, on the one hand, and said film transporting means and said film take-up spool, on the other hand, said coupling means including a transmission and one-way clutch means.
Claim 4
Dependent Claim
55 words
A photographic camera as defined in claim 1, wherein said switching means includes a switching element displaceable between two different positions in dependence upon the switching of the electric motor to a respective one of said directions of rotation, said locking means including a locking element connected with said switching element of said switching means.
Claim 5
Dependent Claim
30 words
A photographic camera as defined in claim 3, wherein said locking element of said locking means is connected with said switching element of said switching means in a frictional manner.
Claim 6
Dependent Claim
29 words
A photographic camera as defined in claim 3, wherein said locking element of said locking means is connected with said switching element of said switching means in interengaging manner.
Claim 7
Dependent Claim
37 words
A photographic camera as defined in claim 3, wherein said switching element of said switching means is formed as a slider, said locking element of said locking means being formed as a lever connected with said slider.
Claim 8
Dependent Claim
37 words
A photographic camera as defined in claim 3, wherein said switching element of said switching means is formed as a lever, said locking element of said locking means being formed as a slider connected with said lever.
Claim 9
Dependent Claim
62 words
A photographic camera as defined in claim 1; and further comprising a cover movable relative to said viewfinder between closed and open positions so as to cover and expose said viewfinder, respectively, said switching means being connected with said cover so that when said cover moves between said closed and open positions, said objective is displaced between said retracted and extended positions.
Claim 10
Dependent Claim
45 words
A photographic camera as defined in claim 8; and further comprising a further switching means arranged so that after terminating the displacement of said objective said first mentioned switching means is returned to its condition in which it is coupled with said film transporting means.
Claim 11
Dependent Claim
19 words
A photographic camera as defined in claim 8, wherein said cover of said viewfinder is formed as a handle.
Claim 12
Dependent Claim
47 words
A photographic camera as defined in claim 1, wherein said film take-up spool has a transmission including a toothed wheel, said locking means having a displaceable member provided with a locking tooth which is engageable with said toothed wheel of said transmission of said film winding spool.
Claim 13
Dependent Claim
29 words
A photographic camera as defined in claim 11, wherein said displacing member of said locking means is formed as a lever, said locking tooth being provided on said lever.
Claim 14
Dependent Claim
29 words
A photographic camera as defined in claim 11, wherein said displaceable member of said locking means is formed as a slider, said locking tooth being provided on said slider.
