In the above embodiment, the shift register 2 is used as the memory.
Although the case of 9 was explained using 0, it is of course possible to use other storage means such as a cascade of flip-flops and a 9 counter, and the stored contents may also include, for example, alarm setting time, timer setting time, time difference time, etc. etc., and need not be used in this embodiment.

Further, in the above embodiment, the case is shown in which it is implemented in a clock device that only displays the time as an external device, but it can also be implemented in the same way as in the above embodiment in a clock device equipped with a clock function such as a calendar function. It is.

Furthermore, in the above embodiment, data is input using two sets of photocouplers, but the number of photocouplers is not limited to two, and can be set to any number as necessary. be.
