Abstract
In a camera which is provided with a clock which operates according to electrical power supplied from a battery, the date and time of photography are imprinted based upon the date and time output from the clock. When the changeover of the battery is detected, the recording of the date and time of photography is prevented, and when the date and time of the clock have been reset the prevention of recording of the date and time of photography is ceased. Further, in a camera which is provided with a clock which operates according to electrical power supplied from a battery, and with a display device which alternatively displays either the date and time output from the clock or the film frame number, when the changeover of the battery is detected, forcibly the date and time output from the clock are displayed on the display device.
