Abstract

PURPOSE: To obviate stopping of clocking of clocking circuit groups for imprinting by charging the secondary battery for data imprinting circuits by the other power source provided in combination in the camera.
CONSTITUTION: The clocking pulses generated by the oscillator OS and dividers BN1 thru BN3 driven by a secondary battery NB are counted in clocking circuit groups CN1 thru CN3, whereby counting of the year, month, date, etc. is accomplished. This clocking data are displayed by 7-segment display elements SE1W SE3 and are imprinted in the film at the time of photographing. On the other hand, the output of the NAND gate NA1 to which the divided output of the divider BN1 is added inverts to a low level during the time of a fixed period out of one month, etc., to conduct a transistor 21 which in turn causes the battery NB to be so charged by way of power source batteries BT1, BT2 provided in combination to the camera as not to be overcharged thereby obviating the stoppage of the clocking circuit groups CN1 thru CN3 being driven by the battery NB. Hence, the operations for adjusting these counters at every photographing are not required.
