Abstract
Abstract A self-timing shutter release control device comprises a self-timing shutter release setting device for setting the number of repetitions of self-timing shutter releases, a controller for continuously repeatedly operating a shutter drive system and a power-driven film advancing system in accordance with the number of repetitions of shutter releases set by the setting device, and a display controller for displaying the set number on a display member. The self-timing shutter setting device includes an externally operable member which is operated as many times as the desired number of repetitions of self-timing shutter releases to set the number of repetitions of self-timing shutter releases in the self-timing shutter release setting device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
A self-timing shutter release control device for use in a camera which has self-timing shutter releasing means, power-driven film advancing means and display means for displaying the number of film frames available in the camera, said control device comprising setting means including an externally operable member for setting the number of repetitions of self-timing shutter release to be continuously effected; control means for controlling said self-timing shutter release means and the film advancing means to operate continuously as many times as the number of repetitions of self-timing shutter releases set in said setting means; and display control means for changing the display mode of said display means from an ordinary display mode corresponding to the number of film frames available in the camera to a self-timing display mode corresponding to the number of repetitions of self-timing shutter releases set in said setting means.
Claim 2
Dependent Claim
143 words
A self-timing shutter release control device for use in a camera which has self-timing shutter releasing means, power-driven film advancing means and display means for displaying the number of film frames available in the camera, said control device comprising setting means including an externally operable member for setting the number of repetitions of self-timing shutter release to be continuously effected; control means for controlling said self-timing shutter release means and the film advancing means to operate continuously as many times as the number of repetitions of self-timing shutter releases set in said setting means; and display control means for changing the display mode of said display means from an ordinary display mode corresponding to the number of film frames available in the camera to a self-timing display mode corresponding to the number of repetitions of self-timing shutter releases set in said setting means.
Claim 3
Dependent Claim
39 words
A control device as defined in claim 1, wherein said externally operable member is an electric switch which is operated as many times as the number of repetitions of self-timing shutter releases to be set in said setting means.
Claim 4
Dependent Claim
26 words
A control device as defined in claim 2, wherein said display means is changed in display mode upon the first operation of said externally operable member.
Claim 5
Dependent Claim
29 words
A control device as defined in claim 3, wherein said display means changes a displayed number by an increment of one for every operation of said externally operable member.
Claim 6
Dependent Claim
34 words
A control device as defined in claim 4, wherein said setting means is reset when said number of repetitions of self-timing shutter releases exceeds the maximum number of film frames available in said camera.
Claim 7
Dependent Claim
24 words
A control device as defined in claim 3, wherein said display means changes a displayed number by a decrement of one for every exposure.
Claim 8
Dependent Claim
26 words
A control device as defined in claim 3, wherein said display means displays a sign showing said camera in a self-timing shutter release mode of operation.
Claim 9
Dependent Claim
17 words
A control device as defined in claim 3, wherein said display means is an LCD display device.
Claim 10
Dependent Claim
26 words
A control device as defined in claim 1, and further comprising means for indicating that the camera is being operated in a self-timing shutter release mode.
Claim 11
Dependent Claim
28 words
A control device as defined in claim 9, wherein said indicating means is an LED to flash on, blink and then flash off for every self-timing shutter release.
