Abstract: 1310026 Photographic shutters POLAROID CORP 29 June 1970 [30 June 1969] 31406/70 Heading G2A Shutter blades 18, 26 are moved from the initial position shown to a terminal position to control the passage of light through an exposure aperture 22, the blades being returned to their initial positions by a reciprocably movable engaging member 150 which is reciprocably driven by a motor between first and second positions, the motor being rendered effective to drive the engaging member upon the blades reaching their terminal positions, and being rendered ineffective to drive the engaging member when the member returns to its first position. Both blades are  pivoted at 20 and urged towards their terminal  positions by springs 30, 40 respectively. The blades are held in their initial positions by latches 48, 50 which each carry armatures 66, 84 abutting electromagnets 68, 86 respectively. Depression of release button 132, pivoted at 102, closes a switch S 1  to energize the electromagnets via a photo-sensitive control circuit, and pivots a latch 120 which prior to exposure holds a loading arm 100 so that the armatures abut the electromagnets. Release of arm 100 allows camera operations as described in Specification 1310027 after which electromagnet 68 is de-energized to disengage portions 56, 60 and blade 18 pivots to uncover the exposure aperture. Blade 18 rotates until a striking surface 352 thereof comes into contact with a striking tip 318 of a resiliently mounted arm 304 which pivots about 306 until a push stud 310 mounted thereon enters a slot 162. Lever assembly 280 then pivots clockwise about 284 and the blade is resiliently brought to rest until tab 350 contacts tab 354. Rotation of assembly 280 causes a bearing member 294 to close flash synchronizing contacts S 3  and also motor switch contacts 334, 336. Blade 26 is freed to terminate the exposure upon de-energization of electromagnet 86. The motor circuit is completed when switch S 1  is opened by release of button 132. An engaging member 154 is then driven reciprocatlngly via a shaft 152 from a first position shown in a counter-clockwise direction to restore blade 18, and hence blade 26 by virtue of mutual contact at 62, 64, to its initial position. At the same time a ram 210 moves loading arm 100 to a position where latch 120 remakes. Upon return of engaging member 154 to its first position, a surface 160 pivots assembly 280 counter-clockwise until stud 310 moves out of slot 162 and contacts 334, 336 are opened whereupon the motor is de-energized and dynamically braked by closure of contacts 332, 336. An embodiment is described in which an alternative simplified construction is given in place of assembly 280.
