发明名称 FILM SENSITIVITY COMPENSATED LIGHT MEASURING NETWORK AND FILM MAGAZINE
摘要 A camera includes a light responsive network having a pair of first and second terminals the resistance between which varies the network sensitivity and which are connected to first and second contact elements exposed in the camera film magazine chamber. A film magazine carries a resistor tape whose value corresponds to the film sensitivity and which is releasably engaged by the contact elements to correspondingly vary the network sensitivity. Alternatively, a plurality of spaced second contact elements are provided which are connected to the second network terminal through respective resistors and the film magazine carries a conductor tape of a shape and position in accordance with the film sensitivity and which engages predetermined second contact elements to provide a resistance between the network terminals to adjust its sensitivity in accordance with the film sensitivity. The resistor or conductor tape is the pressure sensitive tape securing the magazine cover.
