Abstract
Abstract A camera which has the capability of making exposures according to apertu distance, and exposure-time settings and which can also make flash exposures is provided with a housing which carries an adjustable structure movable with respect to the camera housing to provide one of the above settings, this adjustable structure also having a flash position at which it can be set with respect to the camera housing. An electronic flash device is capable of being removably connected with the camera housing by way of a connecting structure carried in part by the flash device and in part by the camera housing. This electronic flash device has a normally open switch which must be closed to render the electronic flash device operative. A switch-operating member is movably carried by the camera housing for movement with respect thereto between a rest position and a switch-closing position where the switch-operating member cooperates with the switch of the flash device to close the latter switch. The adjustable structure when displaced to its flash position engages the switch-operating member to displace the latter to its switch-closing position so as to render the flash device operative.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
In a camera which is adapted to make exposures according to aperture, distance, and exposure-time settings and which also is adapted to make flash exposures, housing means, adjustable means movably carried by said housing means for providing one of said settings, and said adjustable means having with respect to said housing means a predetermined flash position, electronic flash means and connecting means carried in part by said electronic flash means and in part by said housing means for removably connecting said electronic flash means to said housing means, said electronic flash means having a normally open switch which must be closed to render said electronic flash means operable, and switch-operating means carried by said housing means for movement with respect thereto from a rest position to a switch-closing position where said switch-operating means cooperates with said normally open switch to close the latter when said electronic flash means is connected to said housing means by said connecting means, said adjustable means when displaced with respect to said housing means to said flash position thereof engaging said switch-operating means for displacing the latter to said switch-closing position thereof for rendering said electronic flash means operable when said adjustable means is placed in said flash position thereof.
Claim 2
Dependent Claim
205 words
In a camera which is adapted to make exposures according to aperture, distance, and exposure-time settings and which also is adapted to make flash exposures, housing means, adjustable means movably carried by said housing means for providing one of said settings, and said adjustable means having with respect to said housing means a predetermined flash position, electronic flash means and connecting means carried in part by said electronic flash means and in part by said housing means for removably connecting said electronic flash means to said housing means, said electronic flash means having a normally open switch which must be closed to render said electronic flash means operable, and switch-operating means carried by said housing means for movement with respect thereto from a rest position to a switch-closing position where said switch-operating means cooperates with said normally open switch to close the latter when said electronic flash means is connected to said housing means by said connecting means, said adjustable means when displaced with respect to said housing means to said flash position thereof engaging said switch-operating means for displacing the latter to said switch-closing position thereof for rendering said electronic flash means operable when said adjustable means is placed in said flash position thereof.
Claim 3
Dependent Claim
52 words
The combination of claim 1 and wherein said housing means has an outer wall formed with an opening receiving part of said switch-operating means, and said adjustable means when displaced to said flash position thereof displacing said switch-operating means at said opening in part outwardly beyond said wall of said housing means.
Claim 4
Dependent Claim
25 words
The combination of claim 1 and wherein said switch-operating means is in the form of a lever supported for turning movement by said housing means.
Claim 5
Dependent Claim

The combination of claim 1 and wherein said switch-operating means is in the form of a pin supported for longitudinal movement by said housing means.
Claim 6
Dependent Claim
26 words
The combination of claim 1 and wherein said adjustable means is carried by said housing means for movement with respect thereto along a substantially straight path.
Claim 7
Dependent Claim
22 words
The combination of claim 1 and wherein said adjustable means is carried by said housing means for rotary movement with respect thereto.
Claim 8
Dependent Claim
45 words
The combination of claim 6 and wherein said adjustable means is turnable about an optical axis and carries a cam which engages said switch-operating means for displacing the latter to said switch-closing position thereof when said adjustable means is turned to said flash position thereof.
