Zusammenfassung: | PURPOSE:To discriminate whether or not a cartridge is a film cartridge provided with code parts by allowing 2nd-6th code parts selectively to conduct or not to conduct to a 1st code part corresponding to the apex value of the sensitivity of a film housed in the film cartridge. CONSTITUTION:The code parts 1-6 are set on the back cover side of the plane part of the drawing part of the film F in the cartridge P and electrodes group S1-S6 corresponding to the code parts are provided on the back cover. Signals are outputted from the electrodes S1 and S4 of the electrodes group corresponding to the conductive parts 1 and 4 of the code parts. On the other hand, a circuit which reads the outputted signals and makes the read value displayed on a display part 51 and communication pins S7 and S8 for simultaneously transmitting the value to a camera body side are provided on the back cover. Therefore, the read information is transmitted to the camera side and processed as exposure information on the camera side. Thus, the sensitivity of the film F loaded in the cartridge P can be automatically detected and it can be discriminated that the cartridge is not the film cartridge P provided with the code parts when there are not any code parts 1-6 which conduct to the 1st code part. |
