REMOTE CONTROL SYSTEM FOR PHOTOGRAPHIC APPARATUS
First Claim
1. In combination with photographic apparatus having a control system actuable to serially perform operational events in a predetermined order from first to last defining a photographic cycle and first switch means adapted to actuate said control system;
- means for bypassing said switch means and actuating said control system from a location remote from said photograph apparatus, including;
first plural electrical contacts;
second switch means for serially opening and closing said first plural electrical contacts; and
means for delaying the opening of said contacts by said second switch means for a predetermined interval following the closing of said contacts.

Abstract
Photographic apparatus and a remote control system therefor which functions to carry out a series of operational events in response to the brief manual depression of a remote start switch. The control system incorporates an electronic latch which is activated only after select initial ones of these operational events are carried out. Additionally, the control system incorporates a feature insuring the successful commencement of a photographic cycle by delaying the deactuation of the start switch after a brief depression thereof.

-
2. The invention as described in claim 1, wherein said control system is adapted to discontinue said serial operational events when actuated by said first switch means for a predetermined time interval less than said delay interval effected by said delaying means.
-
3. The invention as delineated in claim 2, wherein said first plural electrical contacts are connected in parallel with said first switch means and further including second plural electrical contacts and means for serially connecting said first and second plural electrical contacts.
-
4. The invention according to claim 3 wherein said serially connecting means comprises a conductive cable and plug assembly with said plug adapted to engage said first plural electrical contacts and said cable being connected to said second plural electrical contacts.
-
5. The invention as recited in claim 4, wherein said second switch means includes electrically conductive means movable between first and second positions whereat it is engaged and disengaged, respectively, with said second plural electrical contacts.
-
6. The invention pursuant to claim 5, wherein said second switch means includes means for manually engaging and automatically disengaging said second plural electrical contacts engaging means.
-
7. The invention according to claim 6, further including means for moving said electrically conductive means whilst it remains in engagement with said second plural electrical contacts.
-
8. The invention as delineated in claim 7, wherein said predetermined delaY interval is determined by the length of said electrically conductive means and its rate of movement whilst engaging said second plural electrical contacts.
-
9. The invention pursuant to claim 8, further including a housing and a wheel member rotatably secured within said housing and wherein said electrically conductive means is disposed about a predetermined portion of the periphery of said wheel member.
-
10. The invention as recited in claim 9, wherein said second plural electrical contacts are adapted to be resiliently urged into contact with the periphery of said wheel member to control the rate of rotation of said wheel member.
-
11. The invention pursuant to claim 10, additionally including a shaft slideably disposed within said housing;
- a rack member slideably disposed along said shaft; and
a pinion coaxially fixed to said wheel member for rotation therewith and adapted to engage said rack member such that movement of said rack member along said shaft will effect rotation of said wheel member.
- a rack member slideably disposed along said shaft; and
-
12. The invention as recited in claim 11, further including an actuator spring adapted to be loaded, upon movement of said shaft in a first direction from an initial position to a first predetermined position, so as to urge said rack member in said first direction;
- first latch means for retaining said rack member at an initial position until said shaft reaches said first position;
return spring means for biasing said shaft toward said initial position;
second latch means for securing said shaft in said first position against the bias of said return spring means; and
release means for disengaging said second latch means and permitting said shaft to return to said initial position.
- first latch means for retaining said rack member at an initial position until said shaft reaches said first position;
