Abstract

PURPOSE: To stably operate the watch part even if source voltage fluctuates at the lighting of the light emitting diode of the display part by connecting a filter between the watch part and electric power source in the data imprinting circuit of the camera having the watch part and display part.
CONSTITUTION: Electric power source terminals A, B are divided to the display part 1 which consumes large electric current at the data imprinting and a watch part 2 consisting of a large-scale integrated circuit, so-called LSI, in which microcurrent is flowing at all times. A filter consisting of a resistance R1 and a capacitor C1 is inserted therebetween. Hence, this turns out that the watch part 2 is applied with the voltage of a battery 3 which has been stabilized by the filter, thus even if the voltage of the battery 3 drops owing to the ON of the light emitting diode in the display part 1 at the imprinting of data, it stably operates.
