Abstract
Abstract A striker unit is disclosed for use in the firing of percussionignitable photoflash lamps. During striking operation the unit actuates operation of a shutter and moves into percussion contact with a flashlamp. One embodiment disclosed utilizes a two-part striker unit which provides for withdrawal of the striker unit to a noninterfering position spaced from the lamp firing station.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
In a camera having a shutter and means for receiving a flash lamp fireable by striking an impact receiving element located at a firing site, a combination shutter and flash actuating mechanism comprising: a shutter operating member mounted for movement from a first position to a second position to actuate said shutter; a stop positioned to engage and abruptly stop said shutter operating member; a striking member resiliently coupled to said shutter operating member for movement therewith until said shutter operating member contacts said stop and movable after such contact against the bias of said resilient coupling into striking engagement with an impact receiving element located at said firing site and further movable by said resilient coupling to a position spaced from said firing site after such striking contact; and means for moving said shutter operating member from said first position to said second position.
Claim 2
Dependent Claim
145 words
In a camera having a shutter and means for receiving a flash lamp fireable by striking an impact receiving element located at a firing site, a combination shutter and flash actuating mechanism comprising: a shutter operating member mounted for movement from a first position to a second position to actuate said shutter; a stop positioned to engage and abruptly stop said shutter operating member; a striking member resiliently coupled to said shutter operating member for movement therewith until said shutter operating member contacts said stop and movable after such contact against the bias of said resilient coupling into striking engagement with an impact receiving element located at said firing site and further movable by said resilient coupling to a position spaced from said firing site after such striking contact; and means for moving said shutter operating member from said first position to said second position.
Claim 3
Dependent Claim
81 words
In a camera having an electrical switch and a shutter timed by an electronic timing circuit actuable by closing of said switch, the improvement comprising: means for receiving a photoflash lamp fireable by striking an impact receiving element located at a firing site; means movable into striking engagement with an impact receiving element located at said firing site for firing said lamp; and means movable with said firing means for closing of said switch in timed relation with said striking engagement.
Claim 4
Dependent Claim
81 words
In a camera having an electrical switch and a shutter timed by an electronic timing circuit actuable by closing of said switch, the improvement comprising: means for receiving a photoflash lamp fireable by striking an impact receiving element located at a firing site; means movable into striking engagement with an impact receiving element located at said firing site for firing said lamp; and means movable with said firing means for closing of said switch in timed relation with said striking engagement.
Claim 5
Dependent Claim
159 words
In a camera having an electrical switch and a shutter timed by an electronic timing circuit actuable by closing of said switch, the improvement comprising: means for receiving a photoflash lamp fireable by striking an impact receiving element located at a firing site; firing means including, a timing circuit switch closing member mounted for movement from a first position to a second position for closing said electronic timing circuit switch; a stop for stopping such motion of said closing member; a striking member resiliently coupled to said switch closing member for movement therewith until said switch closing member contacts said stop and movable thereafter against the bias of said resilient coupling into striking engagement with an impact receiving element located at said firing site and further movable by said resilient coupling to a position spaced from said firing site after such striking contact; and means for moving said switch closing member from said first position to said second position.
Claim 6
Dependent Claim
159 words
In a camera having an electrical switch and a shutter timed by an electronic timing circuit actuable by closing of said switch, the improvement comprising: means for receiving a photoflash lamp fireable by striking an impact receiving element located at a firing site; firing means including, a timing circuit switch closing member mounted for movement from a first position to a second position for closing said electronic timing circuit switch; a stop for stopping such motion of said closing member; a striking member resiliently coupled to said switch closing member for movement therewith until said switch closing member contacts said stop and movable thereafter against the bias of said resilient coupling into striking engagement with an impact receiving element located at said firing site and further movable by said resilient coupling to a position spaced from said firing site after such striking contact; and means for moving said switch closing member from said first position to said second position.
