Abstract
Abstract The body of a still camera has a chamber for a film-containing magazine and a one-piece ejector consisting of elastic synthetic plastic material. The ejector has an actuating arm which is connected to or constitutes a pivotable door serving to expose or to seal the chamber against entry of light, and an ejecting arm which brings about at least partial expulsion of a properly inserted magazine in response to movement of the actuating arm to that position which corresponds to open position of the door. A third arm of the ejector is bonded, glued or screwed to the camera body, and the three arms are integrally connected to each other by elastic hinges which constitute weakened portions of the plastic ejector. The actuating arm can be connected to the ejecting arm by coupling elements which cooperate to move the ejecting arm to operative position during a certain stage of movement of the actuating arm to that position which corresponds to open position of the door.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
106 words
In a photographic apparatus particularly in a still camera, a combination comprising a camera body defining a chamber for reception of a film-containing magazine; and ejector means comprising an actuating portion movable between first and second positions in which said chamber is respectively concealed and exposed, and an ejecting portion disposed in said chamber and movable from an inoperative to an operative position to thereby at least partially expel a magazine from said chamber in response to movement of said actuating portion from said first to said second position, said portions of said ejector means being integral with each other and consisting of synthetic plastic material.
Claim 2
Dependent Claim
106 words
In a photographic apparatus particularly in a still camera, a combination comprising a camera body defining a chamber for reception of a film-containing magazine; and ejector means comprising an actuating portion movable between first and second positions in which said chamber is respectively concealed and exposed, and an ejecting portion disposed in said chamber and movable from an inoperative to an operative position to thereby at least partially expel a magazine from said chamber in response to movement of said actuating portion from said first to said second position, said portions of said ejector means being integral with each other and consisting of synthetic plastic material.
Claim 3
Dependent Claim
41 words
A combination as defined in claim 1, wherein said ejector means further comprises hinge means articulately connecting said portions to each other, said hinge means constituting a weakened portion of said ejector means between said actuating portion and said ejecting portion.
Claim 4
Dependent Claim
28 words
A combination as defined in claim 2, wherein at least said weakened portion is elastically deformable in response to movement of said actuating portion between said positions thereof.
Claim 5
Dependent Claim
27 words
A combination as defined in claim 1, wherein said actuating portion constitutes a door which seals said chamber against entry of light in said first position thereof.
Claim 6
Dependent Claim
28 words
A combination as defined in claim 1, wherein said ejector means further comprises an anchoring portion secured to said body and integral with said actuating and ejecting portions.
Claim 7
Dependent Claim
61 words
A combination as defined in claim 1, further comprising a door movable with reference to said body between open and closed positions to thereby respectively expose and seal said chamber against entry of light, said actuating portion being movable from said first to said second position in response to movement of said door from said closed to said open position thereof.
Claim 8
Dependent Claim
47 words
A combination as defined in claim 1, wherein said ejector means further comprises motion transmitting means provided on at least one of said portions and arranged to move said ejecting portion to said operative position in response to movement of said actuating portion to said second position.
Claim 9
Dependent Claim
28 words
A combination as defined in claim 1, wherein said ejector means further comprises an anchoring portion integral with said actuating and ejecting portions and bonded to said body.
Claim 10
Dependent Claim
28 words
A combination as defined in claim 1, wherein said ejector means further comprises an anchoring portion integral with said actuating and ejecting portions and glued to said body.
Claim 11
Dependent Claim
35 words
A combination as defined in claim 1, wherein said ejector means further comprises an anchoring portion integral with said actuating and ejecting portions and mechanical fastener means for securing said anchoring portion to said body.
Claim 12
Dependent Claim
76 words
A combination as defined in claim 1, wherein said ejector means further comprises motion transmitting means including a first coupling element provided on said actuating portion and a complementary second coupling element provided on said ejecting portion, said first coupling element being arRanged to engage and entrain said second coupling element to thereby move the ejecting portion to said operative position in response to movement of said actuating portion from said first to said second position.
Claim 13
Dependent Claim
47 words
A combination as defined in claim 11, wherein said coupling elements comprise projections which engage with each other at least during a part of movement of said actuating portion to said second position to thereby effect the movement of said ejecting portion to said operative position thereof.
Claim 14
Dependent Claim
60 words
A combination as defined in claim 11, wherein one of said coupling elements comprises male coupling means and the other coupling element comprise female coupling means engaged by said male coupling means at least during a part of movement of said actuating portion to said second position to thereby effect a movement of said ejecting portion to said operative position.
Claim 15
Dependent Claim
24 words
A combination as defined in claim 11, wherein said ejecting portion comprises a projection and said second coupling element is provided on said projection.
Claim 16
Dependent Claim
26 words
A combination as defined in claim 11, wherein said coupling elements of said motion transmitting means are integral with the respective portions of said ejecting means.
Claim 17
Dependent Claim
50 words
A combination as defined in claim 1, wherein said ejecting means further comprises an anchoring portion rigid with said body and elastic hinges articulately connecting said anchoring portion with said actuating portion and said ejecting portion, said anchoring portion and said hinges being integral with said ejecting and anchoring portions.
Claim 18
Dependent Claim
57 words
A combination as defined in claim 16, wherein said ejecting means further comprises cooperating motion transmitting elements integral with said actuating and ejecting portions and operative to move said ejecting portion from said inoperative position to said operative position during a predetermined stage of movement of said actuating portion from said first to said second position thereof.
