Abstract
PURPOSE: To control the alarm time accurately in a simple constitution, by generating reference time signal to start counting by an auxiliary counter through auxiliary switch and unlocking switch which are closed a every just time in synchronism with the hands.
CONSTITUTION: An auxiliary switch N composed of a contact and a cam which turns in synchronism with the hands, slipping at the time of forced turning such as time correction is closed at every just time. By switching operation of switches S1, S2 in succession to the manipulation of the winding crown to set a reset lever 9 to the neutral position, minute digit and 10-minute digit memores 41, 42 are reset, and then the alarm set time is stored. When the winding crown is pulled up two steps to close a switch S3, second, minute, and 10-minute digit counters are reset, so that an unlocking mechanism M and switch N are closed, causing FF 69 to generate set output at the just time. This output becomes reference time signal to open AND gate 71. Conuters 38 to 40 continue conunting until the frequency dividing output from a dividing circuit 22 through this AND gate 71 coincides with the setting of the memories 41, 42, so that the alarm time may be accurately controlled in a simple constitution.
