Title: Photographic cameras
IPC: G03B9/70
Filed: 1971-04-19
Abstract: 1346096 Photographic cameras EASTMAN KODAK CO 19 April 1971 [30 March 1970] 25368/71 Heading G2A A camera has an automatic exposure control means 36 for establishing the duration of an exposure interval in response to the intensity of scene illumination detected by a photo-responsive element, auxiliary timing means for terminating an exposure interval a predetermined time after its initiation, and means for changing, on insertion of a flash device, from a first condition in which the exposure aperture is controlled solely by the automatic means to a second condition in which it is controlled by the timing means providing the shorter opening time of the exposure aperture. Operation of camera release 5 allows a pin 4 thereon to move past an arm 6 of a reciprocating member 2 which under the action of a spring 3 moves to the left. With a flash cube 12 inserted in socket 13, a cube sensing plunger 14 is depressed so that a bell crank lever 10 mounted on plunger 14 lies in the path of movement of a lug 9 provided on reciprocating member 2. The flash actuating member 11 is moved upwardly by lever 10 to ignite a flash bulb. The shutter is arranged to open upon energization of an electromagnet and closes upon de-energization of the electromagnet, the power source for the control means 36 being through two serially connected switches 8, 15, the former being closed upon operation of the camera release and the latter closed by contact between 15 and a pin 16 carried on the reciprocating member. The auxiliary timing means operates only upon insertion of a flash cube and arises due to contact between 15, 16 lasting only for a predetermined time, e.g. 1/30 th sec., as the reciprocating member moves to the left. With no flash cube present, contact between 15, 16 is made and retained, the exposure time being determined solely by the light incident upon the photo-cell. Member 2 carries an arm 25 having a lug (26), Fig. 7 (not shown) which engages with recesses (47), Fig. 6 (not shown) provided upon cube socket 13 to provide a cube indexing mechanism which rotates the socket upon movement of member 2 to its initial position. The camera is designed to contain an in-camera processing roller 20 which is coupled to reciprocating member 2 via sprocket 22 and spiral gear 23 so that upon pulling an exposed sheet out of the camera processing is effected and the camera set for the next exposure. Double exposure is prevented by release 5 being held down by engagement of pin 4 with arm 6 until the reciprocating member has been restored to its initial position.
