Abstract
Abstract A still camera wherein the shutter is propelled to open position by an impeller which is cocked in response to transport of the film by the length of a frame and is free to leave the cocked position under the action of a spring in response to actuation of the camera release. The camera includes a built-in flash unit having a socket for flashcubes which is indexed by the impeller during movement back to cocked position. A blocking member which automatically arrests the film-transporting mechanism when the film is advanced by the length of a frame is disengaged from the transporting mechanism in response to movement of the impeller from cocked position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
133 words
In a photographic apparatus, a combination comprising shutter means movable between a plurality of positions and normally assuming one of said positions; actuating means movable from a cocked position to an uncocked position and including a first portion operative to move said shutter means from said one position in response to movement of said actuating means from said cocked position; film transporting means operable to advance the film lengthwise and to thereby move said actuating means from said uncocked position to said cocked position; and illuminating means including a built-in member indexible between a plurality of successive positions, said actuating means further comprising a driving portion rigid with said first portion and arranged to index said member of said illuminating means in response to movement of said actuating means from said uncocked position.
Claim 2
Dependent Claim
133 words
In a photographic apparatus, a combination comprising shutter means movable between a plurality of positions and normally assuming one of said positions; actuating means movable from a cocked position to an uncocked position and including a first portion operative to move said shutter means from said one position in response to movement of said actuating means from said cocked position; film transporting means operable to advance the film lengthwise and to thereby move said actuating means from said uncocked position to said cocked position; and illuminating means including a built-in member indexible between a plurality of successive positions, said actuating means further comprising a driving portion rigid with said first portion and arranged to index said member of said illuminating means in response to movement of said actuating means from said uncocked position.
Claim 3
Dependent Claim
26 words
A combination as defined in claim 1, wherein said actuating means is an impeller and further comprising means for biasing said impeller to said uncocked position.
Claim 4
Dependent Claim
25 words
A combination as defined in claim 2, wherein said shutter means comprises blade means and means for biasing said blade means to said one position.
Claim 5
Dependent Claim
49 words
A combination as defined in claim 1, wherein said member is indexible about a fixed axis and comprises a plurality of equidistant motion receiving portions one of which extends into the path of said driving portion during movement of said actuating means from said uncocked to said cocked position.
Claim 6
Dependent Claim
77 words
A combination as defined in claim 1 for use with roll film of the type having a row of equidistant perforations, one for each film frame, And further comprising blocking means including a tracking portion arranged to engage the film during operation of said transporting means and to enter an oncoming perforation, said blocking means further comprising an arresting portion arranged to arrest said transporting means in response to entry of said tracking portion into such perforation.
Claim 7
Dependent Claim
47 words
A combination as defined in claim 5, wherein said film transporting means is rotatable in a predetermined direction to advance the film lengthwise and comprises a toothed member which is engaged by said arresting portion in response to entry of said tracking position into an oncoming perforation.
Claim 8
Dependent Claim
36 words
A combination as defined in claim 5, further comprising motion transmitting means operative to urge said tracking portion against the film in response to movement of said actuating means from said uncocked toward said cocked position.
Claim 9
Dependent Claim
44 words
A combination as defined in claim 7, wherein said actuating means comprises a portion which bears against said motion transmitting means during movement of said actuating means toward and in said cocked position thereof, said motion transmitting means being pivotable about a fixed axis.
Claim 10
Dependent Claim
21 words
A combination as defined in claim 5, further comprising resilient means for biasing said motion transmitting means against said actuating means.
Claim 11
Dependent Claim

A combination as defined in claim 9, further comprising release means movable between a first position in which it maintains said actuating means in said cocked position and a second position in which said actuating means is free to move toward said shutter means under the action of said resilient means and by way of said motion transmitting means.
Claim 12
Dependent Claim
38 words
A combination as defined in claim 10, wherein said blocking means is arranged to withdraw said tracking portion from the adjoining perforation in response to movement of said motion transmitting means under the action of said resilient means.
Claim 13
Dependent Claim
20 words
A combination as defined in claim 11, wherein said resilient means couples said motion transmitting means with said blocking means.
Claim 14
Dependent Claim
174 words
In a photographic apparatus for use with roll film of the type having a row of equidistant perforations, one for each film frame, a combination comprising shutter means movable between a plurality of positions and normally assuming one of said positions; actuating means movable from a cocked position to an uncocked position and operative to thereby move said shutter means from said one position; film transporting means operable to advance the film lengthwise and to thereby move said actuating means to said cocked position; illuminating means including a built-in member indexible between a plurality of successive positions, said actuating means comprising a driving portion arranged to index said member of said illuminating means in response to movement of said actuating means from said uncocked position; and blocking means including a tracking portion arranged to engage the film during operation of said transporting means and to enter an oncoming perforation, said blocking means further comprising an arresting portion arranged to arrest said transporting means in response to entry of said tracking portion into such perforation.
