Claim 3

A photographic roll film camera as defined in claim 1, wherein said guiding lever has a free end and is provided on said free end with a rotatable roller.

Claim 4

A photographic roll film camera as defined in claim 2, wherein said rotatable roller of said guiding lever is arranged so as to be associated with a perforation region of the film entering said take-up chamber.

Claim 5

A photographic roll film camera as defined in claim 1; and further comprising spring means arranged to bias said lever arm of said guiding lever to abut against said abutment.

Claim 6

A photographic roll film camera as defined in claim 1, wherein said guiding lever has a free end and a portion adjacent to said free end, said guiding lever being concave relative to said wall of said take-up chamber at least in the region of said portion and having a curvature selected to substantially correspond to the first coil of the film roll in said take-up chamber.

Claim 7

A photographic roll film camera as defined in claim 1, wherein said guiding lever has a surface facing away from said wall of said take-up chamber, said guiding lever having a pivoted end and an end opposite to said pivoted end; and further comprising a guide extending from said opposite end of said guiding lever and arranged for guiding the initial portion of the film into said space.

Claim 8

A photographic roll film camera as defined in claim 6, wherein said guide is arranged so as to be associated with a perforation region of the film.

Claim 9

A photographic roll film camera as defined in claim 1; and further comprising a film gate, a rear wall, and a spring-biased guiding plate closing said take-up chamber from said rear wall and forming together with said film gate an inlet slot for introducing the initial portion of the film.

Claim 10

A photographic roll film camera as defined in claim 8, wherein said guiding plate has a guiding arm extending into said take-up chamber toward said wall of the latter.

Claim 11

A photographic roll film camera as defined in claim 7, wherein said guiding plate is supported so that it can turn; and further comprising means for turnably supporting said guiding plate.

Claim 12

A photographic roll film camera as defined in claim 7; and further comprising at least one slide roller arranged in said wall of said take-up chamber in its region associated with perforations of the film.

Claim 13

A photographic roll film camera as defined in claim 1; and further comprising a slide foil arranged along said wall of said take-up chamber.

Claim 14

A photographic roll film camera as defined in claim 1; and further comprising a slide rib arranged along said wall of said take-up chamber in the region associated with perforations of the film.

Claim 15

A photographic roll film camera, comprising means for accommodating a film supply; means forming a spoolless film take-up chamber; a film gate; a rear wall; a spring-biased guiding plate closing said take-up chamber from said rear wall and forming together with said film gate an inlet slot for introducing the initial portion of the film; a guiding body extending into said take-up chamber downstream of said film gate and having a first surface facing toward said take-up chamber and having a shape of a circular cylinder with a diameter at least corresponding to a whole film roll, and a second surface facing toward said rear wall and forming together with said guiding plate an elongated film passage for deflecting the film into said small space; means for transporting a film between said film supply means and said film take-up chamber; and means for forming a film roll in said film take-up chamber, said take-up chamber having a wall which corresponds to a whole film roll and thereby forms one part of said film roll forming means, said film roll forming means further having a spring-biased guiding lever extending into said take-up chamber and bounding together with said wall a small space in said take-up chamber for forming a first coil of the film roll so that an initial portion of the film can be guided into said small space by said guiding lever and thereafter with increase of a diameter of the film roll during winding of subsequent coils said guiding lever turns and thereby said space expands.

Claim 16

A photographic roll film camera, comprising means for accommodating a film supply; means forming a spoolless film take-up chamber; a film gate; a rear wall; a spring-biased guiding plate closing said take-up chamber from said rear wall and forming together with said film gate an inlet slot for introducing the initial portion of the film; a guiding body extending into said take-up chamber downstream of said film gate and having a first surface facing toward said take-up chamber and having a shape of a circular cylinder with a diameter at least corresponding to a whole film roll, and a second surface facing toward said rear wall and forming together with said guiding plate an elongated film passage for deflecting the film into said small space; means for transporting a film between said film supply means and said film take-up chamber; and means for forming a film roll in said film take-up chamber, said take-up chamber having a wall which corresponds to a whole film roll and thereby forms one part of said film roll forming means, said film roll forming means further having a spring-biased guiding lever extending into said take-up chamber and bounding together with said wall a small space in said take-up chamber for forming a first coil of the film roll so that an initial portion of the film can be guided into said small space by said guiding lever and thereafter with increase of a diameter of the film roll during winding of subsequent coils said guiding lever turns and thereby said space expands.

Claim 17

A photographic roll film camera as defined in claim 14; and further comprising a further wall provided with a depression, said guiding lever having an axle defining its axis of turning and arranged in said depression of said further wall.

Claim 18

A photographic roll film camera as defined in claim; and further comprising an objective and a film gate, said depression in said further wall and thereby said axle of said guiding lever being located adjacent to said objective and opposite to said film gate.

Claim 19

A photographic roll film camera as defined in claim 15; and further comprising an edge forming a stop against which said guiding lever abuts to limit a depth of turning of said guiding lever into said take-up chamber.

Claim 20

A photographic roll film camera as defined in claim 17, wherein said edge is formed between said wall of said take-up chamber and said depression of said further wall.

Claim 21

A photographic roll film camera as defined in claim 14, wherein said guiding plate has a guiding arm extending into said take-up chamber toward said wall of the latter and forming together with said second surface of said guiding body said elongated film passage.

Claim 22

A photographic roll film camera as defined in claim 14, wherein said guiding body is connected with said guiding plate and turnably supported together with the latter.
