That is, the control signal is outputted until the second hand 18 reaches the 15-second position.

Next, the overall operation of the electronic timepiece with the above configuration will be explained.

Normally, the function mode designation switch S3 is OFF, so the switching circuits 6, 9, and 14 output the frequency-divided signals P3, P2, and Pl, which are input to the input terminal AK, to the clock drive signal P.
J, the minute hand drive signal PF, and the second hand drive signal PB, so the hour hand 8 and minute hand 16 of the display device 7
, the second hand 18 displays the clock time.

Further, the fast-forward switching circuit 26 also has 1 input to the input terminal A.
Since it is controlled so that the frequency divided signal P1 of seconds is output,
A one second signal is input to the hexadecimal counters 29 and 32 of the second counting circuit 28 and counted. At this time, the above 15
The contents counted by the hexadecimal counter 29 and the second hand position storage circuit 30 are the same as the display position of the second hand 18, and the contents counted by the hexadecimal counter 32 and the quaternary counter 33 are also the same, and the coincidence detection circuit A coincidence signal is output from 61.

When the functional mode designation switch s3 is turned ON from this state, the switching circuit 3.9.14 switches the OR gate 23.2.
4.25, and the fast forward switching circuit 26 is also controlled to output the divided signal P5. The second hand 18 is shown in Figure 2 (A).
The hand is fast-forwarded until it reaches the zero position as shown in FIG. At this time, the hour hand 8 and minute hand 13 are in a stopped state.

Next, in order to select a function from this state, when the function selection input circuit 35 outputs a signal once, the second hand control circuit 27 causes the second hand 18 to move to the alarm function mark AL as shown in FIG. The hand is moved in fast forward motion until it reaches the 15 second position, and the second hand position memory circuit 6
0 also performs a counting operation and outputs position information for 15 seconds. When the second hand position storage circuit 30 outputs the 15-second position information, the function selection circuit 34 outputs the function selection signal P]5, so the function control circuit 19 operates the alarm function circuit 20. An output signal from the alarm function circuit 20 causes the hour hand 8 and minute hand 16 to move rapidly up to the alarm setting time.

In this alarm/mode selection state, the function switch S1 can be used to set the alarm, and the function switch S2 can be used to set the sound to ON or -0FF.

From this state, the function selection input circuit 35 further
When the output 0 signal is output, the second hand 18 is rapidly moved to the position shown in FIG. Since the second position information is output and the function selection signal P30 is output from the function selection circuit 64, the function control circuit 19 causes the timer function circuit 21 to
is operated, and the hour hand 8, minute hand 16, and second hand 18 are rapidly moved to the zero position and enter the timer function state. In this timer mode selection state, the timer time can be set by operating the function switch S1, and the timer start and stop can be controlled by the function switch S2. Next, turn off the function mode designation switch S3 once.
When the function mode designation switch S3 is turned on again after the switch is set to F, the second hand 18 is rapidly forwarded to the zero position.

Then, when a signal is output from the function selection input circuit 35 three times and the second hand 18 is moved rapidly to the stopwatch function mark SW position, that is, the 45 second position, as shown in FIG. 2, the second hand position is memorized. Since the circuit 30 outputs the 45 second position information and the function selection circuit 64 outputs the function selection signal P45, the function control circuit 19 operates the stopwatch function circuit 22, and the hour hand 8 and minute hand 16 are activated. , the second hand 18 is moved rapidly to the zero position, and the stopwatch is started.

In this stopwatch 8 mode selection state, the function switch S1 operates as a start/stop switch, and the function switch S2 operates as a set switch.
