Abstract

1534082 Camera shutter SEIKO KOKI KK 4 Aug 1976 [6 Aug 1975(2)] 32511/76 Addition to 1534081 Heading G2A A shutter has a drive member 9 coupled by a connecting member 10 to an opening actuator 4 for moving opening blades 3 to initiate an exposure; closing blades 6 movable by a closing actuator 7 to terminate the exposure; means 7c for releasing the connecting member 10 just before, at or after exposure termination; and means 7d for transmitting drive from the closing actuator 7 to the opening actuator 4 to return the opening blades 3 to a position in which they at least partially close the shutter aperture 1a. The engagement of parts 7c, 7d of the closing actuator 7 with the connecting member 10 and opening actuator 4 slows the closing actuator 7 and thereby reduces rebound of the closing blades 6. Also, if the closing blades 6 do rebound, light is blocked by the opening blades 3. In Fig. 4 (not shown), the opening actuator 4 and connecting member 10 are inter-connected by a spring (210f). When the closing blades 6 terminate exposure, projection 7c on the closing actuator 7 releases the connecting member 10, projection 7d turns the opening actuator 4 ACW to partially close the aperture 1a and then the spring (210f) turns actuator 4 further ACW to complete closure. In Figs. 5, 6, 7 (not shown), when the closing blades 6 terminate exposure, projection 7c on the closing actuator 7 pushes the connecting member (310) ACW and a projection (310d) of the connecting member turns the opening actuator 4 ACW. to return the opening blades to the closed position.
