In the same figure (B), the time data is converted into a code by converting it into a 24-hour representation and performing 16 evolutions. For example, as shown in the figure, in the case of PM5: 05, it is set to 17:00 in the 24-hour representation, set to "11" in the hexadecimal (HEX) display, converted into 8-bit data (binary number), and converted into a key code. Do

The code transmission process will be described with reference to FIG. 8. First, the reproduction (PLAY) and recording (REC) keys are turned on.
It is judged whether or not it is N (step S111), and if it is ON, the second of the code is transmitted (step S112), and then the minute, hour, day and month data of the code are sequentially transmitted. (Steps S113 to S116). Next, the upper data and the lower data of the code year are transmitted (steps S117 and S11).
8) Transmit the code key mode (step S11)
9) Return to main routine. Also, step S111
If the reproduction or recording key is not ON in step S111, the process proceeds to step S119.

Next, the remote controller input processing on the main body side will be described with reference to FIG. First, with reference to the remote control reception buffer (step S121), it is determined whether or not there is buffer data (step S122). If there is, the clock RAM data of the CPU 233, which is the time-related data setting means.
The data is rewritten (step S123), the code data is referred to (step S124), and the mode is changed by the code key.
The switching flag is set to ON (step S125), and the process returns to the main program. In step S122, even if there is no buffer data, the process returns to the main program. Here, in the RAM of the CPU, a recording area of 8 bits for the upper 2 digits and 8 bits for the lower 2 digits is allocated to the year (YEAR), and the month (MONTH), day (DAY), and hour (HO)
8 for each of UR, minutes (MIN), and seconds (SEC)
A bit recording area is allocated. When this flow is performed, the clock processing of the main flow may be omitted.

As described above, in the time-related data automatic setting device in the camera-integrated image recording device according to the present embodiment, the time and date on the main body side are received by receiving the data on the time and date from the remote controller. The settings can be set quickly and automatically with a simple operation.
