Film sensitivity setting device for camera

Claim 2

A film sensitivity setting device for use in a camera which can be loaded with a film cartridge provided with a sensitivity information indicating a film sensitivity and is provided with means for controlling the exposure of said film and a member for being operated to select one of plural predetermined film sensitivities or the film sensitivity indicated by said sensitivity information, comprising: (a) means for detecting said sensitivity information of said film cartridge; (b) a first area in which plural conductors are formed for indicating said plural predetermined film sensitivities; (c) a second area in which plural conductors are formed for electrically transmitting said sensitivity information detected by said detecting means; (d) contact means for contacting at least a part of said plural conductors in said first area in response to the selection of one of said plural predetermined film sensitivities by said member; (e) connection means for connecting said plural conductors in said first area with said plural conductors in said second area in response to the selection of said sensitivity information; and (f) plural terminals connected to each of plural conductors in said first area, said plural terminals supplying, as an input, the electrical signal showing the film sensitivity selected by said member to said means for controlling the exposure of the film when said contact means contacts at least a part of said plural conductors in said first area and said plural terminals supplying, as an input, the electrical signal showing said sensitivity information to said means for controlling the film exposure through said plural conductors in said first area when said connection means connects the plural conductors in said first area with said plural conductors in said second area.

Claim 3

A film sensitivity setting device according to claim 1, further comprising a circuit board for positioning said plural conductors of said first and second areas on a same plane.

Claim 4

A film sensitivity setting device according to claim 1, wherein said plural terminals produce, as an output, first binary signal indicating the film sensitivity selected by said member when said contact means contacts at least a part of said plural conductors in said first area, while said plural terminals produce, as an output, second binary signal showing said sensitivity information when said contact means contacts said plural conductors in said second area; and wherein the device includes means for converting said first and second binary signals into a third binary signal for being supplied to said means for controlling the film exposure.

Claim 5

A film sensitivity setting device for use in a camera which can be loaded with a film cartridge provided with a sensitivity information indicating a film sensitivity by a first binary code and is provided with means for controlling the exposure of said film and a member for being operated to select one of plural predetermined film sensitivities or the film sensitivity indicated by said sensitivity information, comprising: (a) means for detecting said sensitivity information of said film cartridge; (b) a first area in which plural conductors are formed for indicating said plural predetermined film sensitivities by a second binary code; (c) a second area in which plural conductors are formed for electrically transmitting said sensitivity information detected by said detecting means; (d) contact means for contacting at least a part of said plural conductors in said first area in response to the selection of one of said plural predetermined film sensitivities by said member and contacting said plural conductors in said second area in response to selection of said sensitivity information by said member, said contact means producing, as an output, first binary signal indicating said film sensitivity selected by said member according to said second binary code when said contact means contacts at least a part of said plural conductors in said first area, while said contact means producing, as an output, second binary signal indicating said sensitivity information when said contact means contacts said plural conductors in said second area; and (e) means for converting said first and second binary signals into a third binary signal in accordance with a third binary code to supply said third binary signal to said means for controlling said film exposure, said third binary code being different from said first binary code and said second binary code.

Claim 6

A film sensitivity setting device for use in a camera which can be loaded with a film cartridge provided with a sensitivity information indicating a film sensitivity by a first binary code and is provided with means for controlling the exposure of said film and a member for being operated to select one of plural predetermined film sensitivities or the film sensitivity indicated by said sensitivity information, comprising: (a) means for detecting said sensitivity information of said film cartridge; (b) a first area in which plural conductors are formed for indicating said plural predetermined film sensitivities by a second binary code; (c) a second area in which plural conductors are formed for electrically transmitting said sensitivity information detected by said detecting means; (d) contact means for contacting at least a part of said plural conductors in said first area in response to the selection of one of said plural predetermined film sensitivities by said member and contacting said plural conductors in said second area in response to selection of said sensitivity information by said member, said contact means producing, as an output, first binary signal indicating said film sensitivity selected by said member according to said second binary code when said contact means contacts at least a part of said plural conductors in said first area, while said contact means producing, as an output, second binary signal indicating said sensitivity information when said contact means contacts said plural conductors in said second area; and (e) means for converting said first and second binary signals into a third binary signal in accordance with a third binary code to supply said third binary signal to said means for controlling said film exposure, said third binary code being different from said first binary code and said second binary code.

Claim 7

A film sensitivity setting device according to claim 4, further comprising a circuit board for positioning said plural conductors of said first and second areas on a same plane.
