置。 A film information reading device for reading film information formed on a coded cartridge includes a switch means which is activated when the number of film winding frames is less than 1 and is inactivated when it is 1 or more; A reading circuit that reads out data, a latch circuit that latches the output of this reading circuit and sends it to a camera control circuit such as exposure control, and a power supply to the latch circuit that latches the output of this reading circuit and sends it to a camera control circuit such as exposure control. It is characterized by comprising a circuit that sets the device into a latched state depending on the voltage, and returns to the latched state when the power supply voltage falls below a predetermined value and exceeds the predetermined value again even when the switch means is in an inactive state. A device for reading film information.
