It has a D driver 7 and a date imprinting LED 12. The date control CPU 5 displays the imprinted data on the LCD display unit 11 according to the clock program, and responds to the operation of the date select switch 8, the mode set switch 9, and the mode changeover switch 10 to display the date, time, and time corresponding thereto. The imprinting data is corrected and the imprinting mode is switched and displayed on the LCD unit 11.

Further, by driving the date imprinting LED 12 in response to the imprinting signal from the camera controlling CPU 3, imprinting data is imprinted on the film surface. Also, when the power supply battery 1 is loaded, the display control of the LCD display unit 11 and the initial setting of the imprinting mode are performed. The date imprinting control CPU 5 does not have a function of backing up the imprinting data. Therefore, if the power supply battery 1 is removed, the previous imprinting data disappears. In this way, when the power supply battery 1 is taken in and out, the date control CPU 5
Are reset, eg date is initial set 9
Set as in 6.1.1. If shooting is performed in this state, a date different from the original date will be imprinted, but in order to prevent this phenomenon, the control shown in FIG. Is going.

FIG. 2 is a flow chart showing the control of the operation of the LCD display section performed by the date imprinting control CPU 5 of this embodiment. First, if the power supply battery is inserted for reasons such as battery replacement, a reset signal is given to the date imprinting control CPU 5 via the trigger circuit when the battery is loaded, and as a result, the date imprinting control CPU 5 is power-on reset. It As a result, the date imprinting control CPU 5 recognizes the loading of the power supply battery.

Upon recognition of this power-on reset, the date and clock correction modes are entered, and the date select switch,
In response to the operation of the date set switch and the date mode changeover switch, correction and mode changeover are allowed. Step 101 is a display when the power battery is loaded, and is in a blinking state with all bar display (date off display). This blinking all-bar display gives a warning to the photographer.

Next, when the date select switch is pressed, the year number blinks, and when the date set switch is pressed, the year number is set (step 102). When the date select switch is pressed, the month number blinks, and when the date set switch is pressed, the month number is set (step 103). Similarly, when the date select switch is pressed, the day number blinks, and when the date set switch is pressed, the day number is set (step 104). In the conventional example, it is necessary to press the date mode switch here to enter the clock correction mode, but in the present embodiment, the clock is corrected following the date correction only in the initial setting (step 105, 106).

As described above, if the date and the clock are corrected, the normal operation is performed.

(Second Embodiment) FIG. 3 is a flow chart showing the operation of the second embodiment of the present invention.

The second embodiment will be described with reference to the flowchart of FIG.
