A positioning operation is performed to acquire a positioning result immediately before or immediately after a photographing instruction is given. GPS positioning is performed in response to a positioning start instruction (half depression of the shutter), after which the photographing instruction is issued. GPS positioning and photographing are carried out in order when an operation (full depression of the shutter) serves as both the photographing instruction and the positioning start instruction. When power is on, positioning is performed once and positioning information is held and stored in a saving memory in association with positioning information carried on a photographed image. Alternatively, photographing is performed first and when a power OFF switch is operated after the photographing operation is completed, positioning is performed and positioning information is stored in the saving memory in association with each photographed image. Immediately before series photographing is initiated, GPS positioning is performed and a positioning result is held, and after series photographing is finished, the positioning result is stored in a temporary memory in association with each of serially photographed images stored.

In a battery pack (1), control means (3) reads identification information or operating state detection information out of identification information memory means (4) or battery operating state detection means (10) and inputs it to a modulation circuit (5). The modulation circuit (5) modulates the information into an information signal which can be superimposed on a direct-current power transmission line and sends it to a charging device (20) or a loading device (30) through a positive charge and discharge terminal (11). The charging device (20) or the loading device (30) demodulates the sent information signal to take out the identification information or the operating state detection information and allows power source control means (25, 35) to control the output of charging energy from a charging power source (23) or the output of discharging energy to a load (33). Thus, in addition to the transmission of direct-current power, information can be transmitted only by the connection of two positive and negative terminals.
