The CPU 103 constantly monitors the state of the three switches, that is, the switches 6 to 8. When the switches 6 to 8 are pressed, the logic of each switch input terminal to the CPU 103 is "H". It is detected by changing from the level to the “L” level.

FIG. 2 shows a specific example of a perfect synchronous signal and a timing signal transmitting a signal in a unit of time at a certain fixed period. For convenience of explanation, 1 as shown in FIG.
When the period A is divided into M (M is a natural number of 2 or more) with Ta as the period, the divided Ta / M is defined as F. This F
Is composed of N (N is a natural number of 3 or more) frames. Numbers 0 to M-1 are assigned to M obtained by dividing one cycle A into M, A-0, A-1... A- (M-1), and numbers 0 to N-1 are assigned to respective frames. , F-
0, F-1,... F- (N-1).

Each frame in the transmission data has frame identification information of each frame. That is, F = T
Each of f = Ta / M, F-0 and F-1 ‥ · F- (N-1) is Tf / N = (Ta / M) / N. Each individual identification signal and message of the receiver exist in any of frame units = Tf / N units.

FIG. 2 will be specifically described assuming that 15, N = 128. At power-on, when F-64 of transmission data A-1 is detected (see BS timing in FIG. 2), the elapsed time from the start of one cycle is (Tf × 1) + {(Tf / N) × 64}. = ｛(Ta /
M) × 1｝ + [｛(Ta / M) / N｝ × 64)] = 36
0 seconds = 6 minutes. This elapsed time is obtained by adding the start time of one cycle to the current time, and the time setting ends.

In this embodiment, similarly, when F-32 of the transmission data A-7 is detected at the time of turning on the power, the elapsed time from the start of one cycle is (Tf × 7) + ｛(Tf / N ) × 32｝ = ｛(Ta /
M) × 7} + [{(Ta / M) / N} × 32] = 174
