PURPOSE:To suppress the consumption of a battery when a power source is not always turned off and to reduce the capacity of the power source when the power source is backed up by providing a storage means to a liquid crystal display part which is less in current consumption than a main body and storing camera information from the main body, and allowing the main body to read it out. CONSTITUTION:A register 1 for output is provided as the storage means in a liquid crystal display driving part. The main body can store information of, for example, a counter in the output register 7 previously and read the information out of the output register 1 when the power source is turned on. The output register 1 as the storage means is provided not to the main body which is large in current consumption, but to the liquid crystal display driving part which is small in current consumption, so its projection is facilitated and the load on the battery is reduced.
