In such a state, the contents of the counters 21-27 are uncertain.

Therefore, the crown 2 (shown in the first diagram) is moved from the second home position to the first position.
Pull out the drawer to the drawer position of the third row, rotate it left and right, and remove the dial from dial 3.
The alarm occurrence time displayed on the window 4 (shown in the first diagram) is set to, for example, 7:00 am.

Next, the crown 2 (shown in the first diagram) is positioned at the second pulled out position.

This turns the switch 32 on.

Therefore, the frequency dividing circuit 17, the drive pulse generation circuit 18, and the counter 2L22 are reset, and the drive systems of the hands 8 and 9 are mechanically disconnected.

In this state, the crown 2 (first illustration) is rotated to set the hour hand 8 and minute hand 9 (first illustration) to 7 o'clock OO minutes.

In this state, when the time reaches 7:00 a.m., the crown 2 (shown in the first diagram) is moved from the second pulled out position to the first pulled out position.

By this operation, when the crown 2 (shown in the first diagram) moves from the second pull-out position to the first pull-out position, the switch 31 is turned ON, the memory circuit 25 is reset, and the converter 19 and the counter 2L22 are turned ON. performs normal operation.

In this case, first pull out the crown 2 (first illustration) to the first pull-out position, rotate the crown 2 to the right, and operate until °3'' is displayed on the window 4 (first illustration). .

As a result, the switch 14 is turned ON eight times, and therefore, the time storage counter 27 stores n 8 yl.

Next, rotate the crown 2 (first illustration) to the left and window 4 (
'15' will be displayed in the first figure).

From this, the switch 15 is ONL three times, and therefore the minute storage counter 26 has a value of ? +311 is stored.

In this way, each memory counter 27, 26 has a
"81+ 11311 is stored, but 1131+ I+ 15N is displayed in the window 4 of the dial 3 (first illustration).

This is because the minute storage counter 26 is composed of a decimal counter (and, furthermore, the minute counter 23 is supplied with pulses with a period of 5 minutes from the front counter 21.
When the count contents of the minute counter 23 and the minute storage counter 26 are 1'', this essentially means the count contents of 5 minutes.

With this configuration, the circuit configurations of the minute counter 23, minute storage counter 26, and coincidence detection circuit 28 can be simplified.

In this state, when the time reaches 3:15 p.m., the count content of the minute counter 23 becomes 3'', the count content of the hour counter 24 becomes 8'', and each memory counter 26 of the memory circuit 25
, 27.

As a result, the coincidence detection circuit 28 outputs a coincidence signal for a certain period of time, and the alarm generation device generates an alarm sound, which is outputted by the speaker 34.

Thus, by setting the crown 2 (shown in the first diagram) to the first regular position, the calendar mechanism can be operated, and by setting the crown 2 to the second regular position, the alarm generating device can be operated. can be done.
